Description
Technical Field
[0001] This invention relates to the field of agricultural production technology, and in particular to a fruit harvesting and storage device. Background Technology
[0002] In orchards, harvesting ripe fruit from trees is a time-consuming and laborious task, especially picking fruit from the top of the tree. Currently, various fruit harvesters designed for tall fruit trees are available on the market. These harvesters typically have soft fruit bags. However, during harvesting, because the fruit is surrounded by branches, it is easily caught or even damaged. For lighter fruits, such as citrus and lemons, the fruit bag may bump into nearby branches as it approaches the fruit, causing the fruit to move and directly impacting harvesting efficiency. It also makes it difficult to properly pick the fruit and place it in the fruit bag, resulting in inconvenience. Summary of the Invention

[0044] The working principle of this invention is as follows:
[0045] like Figures 1 to 4As shown, during use, the vehicle body 1 is moved to the fruit tree. The height of the fruit picking mechanism needs to be adjusted according to the height of the target fruit. Specifically, the controller first starts the transmission motor 14, which drives the lead screw 13 to rotate and simultaneously drives the screwed connecting block 15 to move upward along the axis of the guide boss 17 from the guide groove block 16, that is, to move upward on the bracket 10. After moving to the appropriate height, the transmission motor 14 is turned off, and then the second telescopic cylinder 12 is started. The extended end of the second telescopic cylinder 12 drives the fruit picking mechanism to move to the target position of the fruit picking. At the same time, the output end of the second telescopic cylinder 12 is also pulled by the front bracket 5 to one end of the snake tube 51. When the output end of the second telescopic cylinder 12 moves into place, that is, the snake tube 51 is in the straightened position, the fruit picking mechanism is located above the snake tube 51.
[0046] Then, based on the image acquired by camera 8, determine the position between the shearing board 37 and the target fruit, such as... Figure 1 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the controller first starts the first telescopic cylinder 11, which drives the cylinder body of the second telescopic cylinder 12 to rotate around the support rod 19. That is, it further adjusts the height of the fruit picking mechanism in the vertical direction. When it reaches the fruit position, the first hollow rotating platform 2 is started according to the position of the branch connected to the fruit. The first flange 21 drives the support frame 20 to rotate, that is, it drives the fruit picking mechanism to rotate in the longitudinal direction of the second telescopic cylinder 12, adjusting the longitudinal angle of the two shears 37 cutting the branches. If the angle between the cutting surface of the two shears 37 and the axial direction of the branch is small, the second hollow rotating platform 3 is started. The second flange 31 drives the mounting sleeve 32 and the mounting cylinder 36 to rotate synchronously, that is, it drives the two shears 37 connected to the mounting cylinder 36 to rotate synchronously, so as to adjust the lateral angle of the two shears 37 cutting the branches.
[0047] Then, the controller starts the first telescopic cylinder 11, and the output end of the second telescopic cylinder 12 drives the two shear plates 37 to move towards the branch position of the target fruit. After the two shear plates 37 move to both sides of the branch position, the first telescopic cylinder 11 is closed. Then, the controller starts the second drive motor 33, which drives the transmission rod 34 to rotate. Since the outer wall of the rotating rod 34 is provided with a corrugated groove 4 along the circumferential direction, the guide post 43 in the corrugated groove 4 moves with the wave and drives the connecting plate 40 and the pull rod 35 connected to it to move synchronously. That is, it drives the pull rod 35 to move back and forth in the axial direction of the mounting cylinder 36, thereby driving the two shear plates 37 to move back and forth at the same time, thus forming a shearing action, which can cut the branch and achieve the purpose of picking the target fruit. Similarly, it can also be used for pruning operations when there is interference with the branch. It is flexible in use and can improve the fruit picking efficiency.
[0048] Among these, such as Figure 8 and Figure 9 As shown, a connecting sleeve 41 is screwed onto the connecting plate 40, and a placement groove 42 is provided on the connecting sleeve 41. The bottom of the placement groove 42 is connected to one side of the compression spring 48, and the other side of the compression spring 48 is connected to one end of the guide post 43. This ensures that the guide post 43 moves smoothly in the corrugated groove 4, that is, it ensures the smoothness of the reciprocating movement of the pull rod 35 and the shearing action of the two shear plates 37.
[0049] It should be noted that, since the snake bone tube 51 is at an angle at this time, the fruit being cut and picked is not directly above the upper end of the snake bone tube 51. That is, the cut fruit cannot accurately fall into the snake bone tube 51 at this time. Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 10 As shown, during the aforementioned operation, the rotation of the second drive motor 33 is controlled, and the two shears 37 are moved to the position to clamp the branch. At this time, the branch is not cut. Then, the first drive motor 22 is started, and the first flange 21 drives the swing shaft 23 to rotate. Simultaneously, the connecting column 26 inserted in the step hole 24 moves along the first positioning groove 29 in the front and back directions. That is, the entire fruit picking mechanism rotates in the front and back directions. This simultaneously drives the two shears 37 to clamp the branch and move the target fruit to the top of the snake bone tube 51. After it is moved into place, the second drive motor 33 is started again to drive the two shears 37 to cut the branch, and the target fruit can fall directly into the snake bone tube 51.
[0050] Repeat the above steps to pick and store the remaining target fruits.
[0051] like Figure 1 As shown, because a net 53 is provided at the gap at the lower end of the snake-bone tube 51, it can prevent fruit from falling out and avoid fruit getting stuck in the gap. Therefore, fruit falling into the snake-bone tube 51 can quickly move down into the flexible tube 52. Since the discharge end of the flexible tube 52 is set vertically, and an airbag 60 is wrapped around the inner wall of the discharge end of the flexible tube 52, the fruit falling into the airbag 60 is wrapped and its free fall speed is slowed down to prevent the fruit from being damaged. Among these, the airbag 60 is wrapped around the flexible tube 52. To prevent the fruit from being tightly wrapped and thus hindering its removal, an air inlet valve 61 connected to an air pump is provided on one side of the flexible tube 52, and an exhaust valve 62 connected to one side of the airbag 60 is provided on the other side. The other side of the airbag 60 is connected to the air inlet valve 61. This allows for timely adjustment of the fruit passage diameter in the position of the airbag 60. Finally, the fruit falling into the inclined discharge cylinder 70 is moved out of the inclined discharge cylinder 70 by gravity along several inclined rollers 74 for collection.
[0052] Throughout the entire process, the image acquired by camera 8 is used to determine the position of the fruit and then to perform precise operations on the controller. Camera 8, which is aimed at the fruit picking mechanism, should be aligned with the shearing plate 37. In order to better determine the spatial position of the fruit and the shape of the branches so as to adjust the angle, it is advisable to set up multiple cameras 8 on the inclined support rod 80.
[0053] It should be noted that the first hollow rotating platform 2, the second hollow rotating platform 3, and the third hollow rotating platform 30 have the same structure and are all existing technologies. Their structure and operating principle are as follows: Figure 12 As shown, it includes a turntable and a servo motor connected to the side of the turntable. The turntable has a hollow structure, and a boss is provided in the hollow structure to engage with the through hole in the middle of the roller bearing. A gear is fitted on the outside of the roller bearing, and the gear is meshed with the transmission gear connected to the output end of the servo motor. A flange is connected to the end face of the roller bearing. The flange is used to connect with the working parts, which will not be described in detail here.
[0054] Therefore, in this embodiment, at the position of the first hollow rotating platform 2, only the support frame 20 is connected to the first flange 21 to drive the entire picking mechanism to rotate along the circumference of the first flange 21. At the position of the third hollow rotating platform 30, only the second telescopic cylinder 12 is connected to the third flange 39, which can drive the picking mechanism to adjust the longitudinal rotation angle twice in one piece, so as to quickly cut off the branches. At the position of the second flange 31, the mounting sleeve 32 is connected to the second flange 31 and passes through the hollow structure of the turntable, that is, it also passes through the inner ring of the roller bearing. In this way, the rotation of the second flange 31 synchronously drives the second drive motor 33, the pull rod 35 and the shear plate 37 to rotate. The two hollow rotating platforms are used together to realize the adjustment of the relevant shearing angles described above. At the same time, it does not affect the second drive motor 33 driving the pull rod 35 and the two shear plates 37 to move back and forth, so as to quickly and effectively pick the fruit.
[0055] After use, remove the threaded hose 52 from the snake-bone tube 51, and then activate the second telescopic cylinder 12 via the controller. The second telescopic cylinder 12 drives the fruit-picking mechanism to move back. At the same time, since there are gaps between each sleeve of the snake-bone tube 51, and the front support 5 is connected to the output end of the second telescopic cylinder 12, and with the rear support 50 hinged to the snake-bone tube 51, the movement of the output end of the second telescopic cylinder 12 also causes the snake-bone tube 51 to bend and retract (e.g., Figure 11 (As shown), to avoid causing movement interference.
[0056] Meanwhile, in this invention, the drive motor, servo motor, transmission motor 14 telescopic cylinder, intake valve 61 and exhaust valve 62 are all connected to the controller.
