The machine has an inverted U-shaped mainframe that supports subframes that define a harvesting area configured to canopy trees inside .
A pair of picking assemblies supported by subframes each incorporate a crop separation mechanism that attaches a tree canopy and rods configured to separate crops from trees, and a motion guided mechanism that provides a snap-like whip for a short time do .
Rod Relative Movement and Canopy Attachment The mechanism that moves the rod in and out of the canopy. The operator area allows the operator to move the machine along the tree line and operate various systems.
The pomegranate and citrus harvesting and harvesting method of the present invention addresses the above problems and provides the advantages identified above.
Namely, the present invention discloses a new and improved harvester specifically configured to harvest pomegranates and tangerines efficiently and efficiently from rows of trees.
Pomegranate cultivation and fruit harvesting began in ancient Persia and spread to the Mediterranean and Black Sea regions where it has been cultivated for thousands of years and then throughout India to arid regions in Asia, East India and Africa.
Spanish colonists introduced pomegranates around 1769 to the Caribbean, Latin America and California.
Pomegranate production in the United States is primarily harvested in the dry regions of California and Arizona. Pomegranates have been cultivated for thousands of years for both ornamental and religious purposes but have recently grown significantly in popularity and are now widely available the main reason for the soaring popularity of pomegranates in general as a juice or juice extract has to do with its health benefits.
Recent research shows that pomegranates are a good source of vitamins, especially vitamins C and B5, potassium and antioxidants, can lower heart disease risk factors and lower blood pressure other studies have shown that pomegranate juice can reduce the chance of certain cancers and diabetes, and potential antiviral bactericidal effects e.g.
The demand for pomegranate juice and products made from pomegranates would increase, as well as increase the cultivation and production of pomegranates significantly.
pomegranate harvesting machine
A method of harvesting a pomegranate or other crop using a harvester of the present invention includes positioning the harvester so that the harvester is aligned with the tree row in the open (retracted rod) And placing inside the canopy a motion-inducing mechanism that vibrates or strikes provides a short snap-like motion to the rod that separates the crop from the tree, much like a storage container, with a transport assembly, separating the crop from the pit that collects and moves the crop from the transport committee.
Accordingly, the primary objective of the present invention is to provide a harvesting machine and method of harvesting pomegranates and citrus that has the benefits described above and which overcomes the limitations and problems associated with currently available harvesting machines and methods for such crops.
It is a primary objective of the present invention to provide a harvesting machine and method that significantly reduces the amount of labor required to harvest pomegranates and citrus, thereby solving problems related to the supply and cost of such labor.
It is also a primary objective of the present invention to provide a harvesting machine and method that facilitates growing pomegranates in a large-scale commercial manner by significantly reducing the amount of labor, time and cost for harvesting such crop.
It is also an important objective of the present invention to provide a harvesting machine and method of harvesting pomegranates and citrus that does not require the shaking of the tree trunk or the individual grasping and removing of the fruit in order to harvest the fruit.
The above and other aspects and advantages of the present invention are explained in greater detail by reference to the attached figures and the description of the preferred embodiment which follows.
As set forth herein, the present invention resides in the novel features of form, construction, mode of operation and combination of the above presently described and understood by the claims.
The most important types of fruit crops production in many countries such as Egypt are oranges and pomegranates.
Therefore, harvesting machine and technical systems are a partial solution to eliminate and reduce costs in these fields.
In economic and time terms, traditional harvesting methods are inefficient.
Pomegranate trees, which are large, often rounded shrubby small trees, typically reach 12 to 16 feet in height and have one or more stems that produce limbs that typically extend tough, spiny secondary sides Pomegranate fruit grows directly from the secondary side leaf.
As is well known, pomegranates are not easily grown from secondary aspects. For this reason, the stems of pomegranate trees are not very strong so for many types of nuts or trees, shaking the stems in this way is generally not a useful way to harvest pomegranates.
Instead, traditional methods of harvesting pomegranates are very labor intensive.
Consequently, large-scale pomegranate cultivation and commercial harvesting requires a large number of workers to separate the crop from the tree Current pomegranate harvesting methods allow workers to walk through tree rows and into trees to pick individual berries Potentially troublesome for as it is thorny, hard to separate stems from sides As well known in the agricultural industry, there are many problems with availability of workers and costs to be paid to them, many of which were traditionally illegal or in the country without proper documentation You will need to secure a large number of skilled workers when you are ready to harvest.
Crops can be destroyed when necessary. Consequently, the cost and availability of labor for pomegranate harvesting risks limiting the ability to produce commercially viable pomegranates on a large scale.
Production Of Pomegranates Harvesting Machine
Harvest as many citrus fruits with the same qualities and issues identified above for pomegranates.
One difference related to the mechanical collection of citrus fruits, especially oranges, is that care must be taken when separating the fruit from the tree so that the stem does not pull the cap away from the skin, leaving a hole in the fruit .
As a result of this problem, mechanical harvesting of citrus fruits is done mainly on harvested fruit for the juice market or when it is necessary to remove fruit damaged by frost or other events The skin is not removed when separated from the tree.
As well known to those skilled in the art, many different types of mechanical harvesters have been developed to harvest fruit. Due to various limitations and problems, very few of these machines are commercially available or in use by growers.
A successful mechanical harvesting machine for harvesting fruit from trees must be able to move to efficiently and effectively and about the orchard from which the fruit will be harvested, move from one tree to another tree and move from one row of trees to another row.
The harvesting machine must also be able to harvest the fruit from substantially the entire tree, including the top, bottom and middle of the tree, in order to avoid having to hand pick much, if any, of the remaining fruit on the tree.
The harvesting machine must also be configured to not damage the tree, including breakage of limbs and trunks, or the fruit, as applicable, that is removed from tree.
Preferably, a harvesting machine for picking fruit from trees will be able to move along a row of trees and harvest fruit from each tree while stopping for as short of time as possible at the tree so as to limit the amount of time required for harvesting too as little as possible.
The harvesting machine type: Honda, model: small harvest, driven by hand, made in Japan with dimensions of 1650 mm length, 170 mm width, 230 mm height and weight of 10 kg consists of parts. The first is a 2.5 hp two-stroke air-cooled petrol engine that carried on the farmer back.
The engine speed is 1650 -1700 rpm and oil consumption of 0.8 L/h. Also, engine has petrol tank volume about 2 liters.
The second is fixed arm has length of 1500 mm with diameter 18 mm and was made of aluminum pipes that is controlled according to the position of the fruit on the tree. There is transmission shaft inside the fixed arm with diameter of 10 mm for transmit the motion from engine to toothed disc head or scissors harvesting head .
The third is toothed disc that consists of three blades made of steel with 250 mm diameter for cutting crop.
Over the years, various attempts have been made to provide a harvesting machine to mechanically harvest citrus. For instance, U.S. Pat. No. 3,485,025 to Bohannon describes a mechanical citrus fruit harvester having a harvesting head mounted on a support platform with a plurality of harvesting fingers projecting from the harvesting head that are vibrated vertically and horizontally to engage and remove fruit from within a tree.

A telescoping chute transfers the removed fruit to a conveyor mechanism that transfers the fruit to a bin or other container. U.S. Pat. No. 5,666,795 to Wilkinson describes a citrus harvesting machine having a plurality of outwardly extending picking arms carried on a driver bar that is moved toward and away from the tree so the picking arms may selectively penetrate the tree canopy.
The picking arms have a generally hook-shaped picking member at their distal end that separates the fruit from the branch during retraction of the picking arms.
A drive mechanism applies a cyclic motion to the individual picking arms to assist in dislodging the fruit from the tree.
A more recent mechanical citrus harvesting machine, available from Oxbo Corp., is a continuous travel canopy shaker that has a plurality of outward extending tines disposed in a generally circular pattern which are inserted into one side of the tree's canopy and then shaken to dislodge the fruit from the tree.
A pair of the machines are moved along the open spaces on either side of a row of trees to remove fruit from trees in the row by rapidly shaking the tines inside the canopy.
A number of workers, such as 25 to 30, follow behind the harvester to collect the fruit that is knocked onto the ground by the harvester.
It is also a primary objective of the present invention to provide an over-the-row harvesting machine and method of using such machine that imparts a snap-like rapid oscillation motion to a plurality of rods that extend into the canopy of a tree to separate fruit from the tree.
Despite the foregoing, what is needed is a harvesting machine and method of harvesting that effectively separates pomegranate and citrus fruit from the tree without damaging the tree or the fruit so that the pomegranates and citrus can be harvested in a more commercially acceptable and efficient manner.
A desirable harvesting machine and method is one that is particularly beneficial for harvesting crops grown on trees having crops, such as pomegranates, that are generally difficult to remove by hand and cannot be safely, efficiently or effectively removed by shaking the trunk of the tree.
Preferably, a harvesting machine and method would allow harvesting of the crop to take place as quickly and efficiently as possible with a low number of laborers and less wasted time and effort so as to facilitate the commercial cultivation of pomegranates and citrus by reducing the overall cost of such harvesting.
The desired harvester and method of harvesting should be able to harvest virtually all or the vast majority of the crop off of the tree in order to reduce the need for follow-up hand harvesting.
The preferred harvester and method of harvesting should substantially eliminate the need to collect fruit off of the ground.
