Spanish colonist introduced the pomegranate to the Caribbean, Latin America and, in approximately 1769, California. Harvest is the time to enjoy the results of your hard work. In order to make better fruit harvesting decisions, the robot needs algorithms capable of learning so that harvesting to be done with fewer errors. Even more specifically, the present invention relates to such mechanical harvesters that utilize a plurality of oscillating rods to separate the crop from the tree and are particularly beneficial for harvesting pomegranates, citrus and the like. Published 4) that is utilized when the user transfers the harvested fruit 14 to bin 34, as shown in FIG. The tapered distal end 118 of rods 26 will help direct the rods 26 around the various limbs 18 in canopy 22 to prevent the insertion of rods 26 from being blocked by such limbs 18. Development of a low-cost tine movement controller to control the movement of the tines of the tractor drawn canopy shaker (TDCS). Adding a special grading conveyor belt to eliminated undersized fruit. Although uniform positioning of the weight members 140 on shafts 136 could provide some of the benefits of the present invention, it is much preferred that there be a mixed oscillation motion to better achieve the snap-like, rapid whipping motion that has been found to be more effective at separating fruit 14 from tree 12. As set fort in the Background above and shown in FIGS. Also, during customization, the digital output from the controller (PIC18F458) has been set such that it can control the tines by communicating with the harvester control system (manual tine controller) directly. See how we display average pricing information, trends and market data. Yield monitors for specialty crops. In a preferred embodiment, the motion inducing mechanism comprises one or more weight assemblies, comprising a weight member attached to a rotating shaft, that are configured to impart the desired whipping motion to the rods.

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. http://edis.ifas.ufl.edu/ae466. In one embodiment, front frame 78 can be fixedly attached to main support frame 28. Evaluation of a self-propelled citrus fruit pick-up machine. Harvesting of citrus as many of the same attributes and issues as identified above for pomegranates. Due to various limitations and problems, very few of these machines are commercially available or in use by growers. Figure A shows a mass removal machine used for harvesting citrus. Find the vendor to meet your needs. A motor supported by the main frame propels the machine along the row of trees. All machines were more effective as the mature fruit abscission force was reduced. FASAE Paper No. Publications, Progress 10/01/11 to 09/30/12OutputsOUTPUTS: The following two specific objectives were pursued for this project: Objective 1: Improve engineering solutions to reduce debris in mechanically harvested fruit: Further improvements were made to the debris removal machine that was redeveloped and modified during previous year. 1, 4 through 8 and 14. If desired, the operator area 40 may be fully enclosed by a shell or like structure. In one arrangement, air at very high speed is discharged from 2 outlets, which is directed towards one side of tree as the machine moves down the row. Regression analysis was performed to find the indirect mass estimation of the trash. ISHS, Acta Horticulturae 824: 267-274.

Once the fruit 14 is received onto the lower conveyors 174, it is directed rearward where, in the preferred embodiment, it is transferred to the pair of rear conveyors 176. As best shown in FIGS. AUTOMATIC TINE CONTROL SYSTEM: 1. 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. Postharvest citrus mass and size estimation using logistic classification model and watershed algorithm. Currently, there is no commercially available yield monitor for citrus harvesting machines. In addition, software was developed to extract field efficiency information from yield data.

Citrus harvesting: Citrus fruit like orange, kinnow, malta and similar such fruits can be harvested by using inertia type limb shakers. As stated above, rear wheels 76 at the back end 44 of harvesting machine 10 are operatively connected to and driven by motor 38 so as to provide the power to move harvester in a forward or rearward direction, as selected by the operator. 2009 Figure A shows a mass removal machine used for harvesting citrus. One pair of Oxbo 3220 harvesters will harvest a million pounds of fruit a day and can replace as many as 120 laborers. Because the transfer conveyor 178 faces forward, generally in-line with the longitudinal length of harvesting machine 10, when not in use, it will be much less likely to contact buildings, telephone poles or other objects that may be along the path that harvesting machine 10 will take as it moves to the orchard. Transaction of Citrus Engineering Conference, V. LV. Bora, G. and R. Ehsani. 2009. As set forth in more detail below, canopy engaging mechanisms 102 of each of the pair of picking assemblies 94/95 move the crop separating mechanism 98 into the harvesting area 60 to insert the rods 26 into canopy 22 of tree 12 (tree engaging position 104), motion inducing mechanism 100 imparts a very short duration, typically approximately four to six seconds per tree 12, snap-like whipping motion to the rods 26 to separate fruit 14 from the tree 12 and the fruit 14 is received by conveying assembly 34 and conveyed to a storage container, such as bin 36. One sliding brace mechanism 172 is also attached to each slider support member 158/160 and configured to allow the slider members 162/164 while allowing them to slide relative to their respective slider support member 158/160. The system is also capable of measuring the amount of trash and yield (based on mass-flow). Evaluating over-the-row harvesting machines for high density and dwarf citrus trees: Diseases such as citrus greening (HLB) or canker have caused Florida citrus growers to consider new alternatives for grove design.

The system is able to float on the ground surface as opposed to digging into and beneath the ground surface. Also several tine modification options have been proposed to reduce tree damage while maximizing the fruit removal. In use, the harvesting machine 10 of the present invention is moved to an orchard having one or more rows 24 of trees 12, such as pomegranate trees, that have fruit 14 thereon that is ready for harvesting. A ram mechanism, disposed between a carrier brace member of the carrier frame and a slider brace member connecting a pair of spaced apart slider support members, is utilized to move the carrier frame and crop separating mechanism. Integrate the machine vision and sensory components with the harvesting gripper, and prototype manipulator under field conditions, employing our visual servo control approaches. The extended de-stemmer removed about 4% more trash (by weight) than the regular de-stemmer. 5) that is useful for moving the harvesting machine 10 to the orchard of trees 12 and, in some circumstances, between rows 24 of trees 12 and for storing harvesting machine 10 when not in use.
