Abstract
Description
Technical Field
[0001] This invention relates to the field of fruit harvesting, and specifically to an intelligent, efficient, and multifunctional fruit harvesting robot. Background Technology
[0002] In orchards, fruits such as apples, pears, olives, walnuts, and camellia oleifera need to be harvested and collected in a timely manner after ripening to ensure fruit quality, prevent overripeness, rot, or damage from pests, maintain fruit taste and flavor, and meet market supply needs.
[0003] The terrain in which fruit trees grow is mostly rugged and uneven. Due to the limitations of terrain and the spacing between fruit trees, conventional harvesting equipment cannot efficiently pick and collect the fruit. Therefore, the current method of harvesting fruit still relies on manual hand-held harvesting equipment to knock the fruit off the tree to the ground for collection. However, mature fruit usually has a short harvest period, and manual harvesting is labor-intensive. Collecting the fallen fruit by hand further increases the labor intensity of workers and also increases the loss of fruit during harvesting. Therefore, there is a need for equipment that can adapt to different terrains and efficiently complete fruit harvesting to assist manual fruit harvesting and reduce the labor intensity of harvesting. Summary of the Invention

[0034] The present invention will be further described below with reference to the accompanying drawings:
[0035] like Figures 1-11 As shown, an intelligent, efficient, and multifunctional fruit harvesting robot includes a frame 1, a control module (not shown), and a collection trough 31 mounted on the frame 1. The frame 1 moves through the orchard via a walking assembly. The frame 1 is equipped with a vision camera 39, a vibration mechanism, a collection mat 3, and a winding mechanism. These components move synchronously with the frame 1. The vibration mechanism is rotatably connected to the frame 1 and its end can continuously vibrate the fruit trees. The end of the vibration mechanism can connect to the fruit trees to generate vibrations that shake the fruit off the secondary and tertiary branches. The winding mechanism is located below the vibration mechanism and is used to lay the collection mat 3 to collect the fruit shaken off by the vibration mechanism and to wind the collection mat into the fruit. In the collection trough 31, the collection mat 3 can be laid under the canopy of the fruit tree to collect the shaken-down fruits under the action of the winding mat. The collection mat 3 can be wound up and recycled by the winding mechanism. When the collection mat 3 is wound up and recycled, the fruits on the collection mat 3 can fall into the collection trough 31. The vision camera 39 can collect canopy information and the number of fruits on the collection mat 3 and feed it back to the control module. The control module estimates the canopy area based on the canopy information collected by the vision camera 39. Based on the estimated canopy area, the control module controls the area of the collection mat 3 laid under the canopy area through the winding mechanism. Based on the number of fruits on the collection mat collected by the vision camera 39, the control module controls the winding mechanism to wind up the collection mat 3 and collect the fruits into the collection trough 31, thereby completing the harvesting and collection of the fruits.

The control module receives, analyzes and processes the collected tree canopy information. Based on the processed information and the tree canopy area estimation method, the control module estimates the tree canopy area and controls the roll-up blanket structure to extend the collection blanket to the corresponding tree canopy area to complete the laying. The vision camera can also identify and collect parameters of fruits, leaves, flowers, etc. scattered on the collection blanket 3 and feed them back to the control module. The control module analyzes the collected parameters to determine the vibration effect of the fruit harvesting robot.
[0037] In this embodiment, as shown in the appendix Figure 1-11 As shown, the vision camera 39 is fixed to the top of the support 2. It can locate and identify the fruit trees to be harvested, collect canopy information, and feed it back to the control module. The control module receives, analyzes, and processes the collected canopy information. Based on the processed information and the canopy area estimation method, the control module controls the roll-up blanket structure to extend the collection blanket to the corresponding canopy area to complete the laying. The vision camera can also identify and collect parameters of fruits, leaves, flowers, etc. scattered on the collection blanket 3 and feed them back to the control module. The control module analyzes the collected parameters to determine the vibration effect of the fruit harvesting robot, so that the robot can automatically adjust the working parameters of the vibration mechanism according to the fruit scattering state. An electrical control cabinet is fixed on the frame. The electrical control cabinet contains a control module (not shown in the figure). The control module is electrically connected to the electric drive working components in the battery module 30, vision camera 39, walking component, roll-up blanket collection mechanism, vibration mechanism, etc., and can control and drive their movement.
[0038] In this embodiment, as shown in the appendix Figure 1 Appendix Figure 3 Appendix Figure 4Two collection mats 3 are symmetrically arranged on the frame 1. Multiple reinforcing ribs 4 are fixed to the collection mats 3, dividing them into units of different sizes. When the collection mats 3 move, the reinforcing ribs 4 also push the fruit on them to move. Preferably, the reinforcing ribs 4 are made of non-metallic material. Multiple magnetic contacts 5 are fixed to adjacent sides of the two collection mats 3, assisting in the closing of the collection mats 3 and reducing gaps between them. The collection mechanism also includes a laying mechanism that drives the collection mats 3 to extend, assisting in the extension of the collection mats 3 under the fruit trees. The collection mechanism also includes a recycling mechanism that winds up and retracts the collection mats 3, assisting in the recovery of the collection mats 3 and the fruit on them.
[0039] In this embodiment, as shown in the appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 As shown, the laying mechanism includes two rail mounting seats 6 rotatably connected to the frame 1. A bracket 2 is vertically fixed on the frame 1. The top of the rail mounting seat 6 can abut against the top of the bracket 2. When the top of the mounting seat abuts against the bracket 2, the bracket 2 can provide support for the rail mounting seat 6. Multiple connecting rods 7 are fixed between two adjacent rail mounting seats 6. An upper rail 8 is slidably connected to each rail mounting seat 6. The upper rail 8 can slide along the rail mounting seat 6. The upper rail 8 is arc-shaped and has a rack A9 fixed on its top surface. A groove is opened on the bottom surface of the upper rail 8. An arc-shaped lower rail 10 is slidably connected in the groove. The lower rail 10 slides relative to the upper rail 8 along the groove. A rack B11 is fixed on the bottom surface of the lower rail 10. The lower track 10 is fixed at one end to the collecting blanket 3. When the lower track 10 moves, it can drive the fixed collecting blanket 3 to move synchronously. The track mounting base 6 is fixed with a drive motor A12 that drives the upper track 8 and the lower track 10 to move respectively. The drive motor A12 is fixed with a drive gear A13, which meshes with rack A9 and rack B11 respectively. The drive motor A12 can drive the upper track 8 to move through the meshing drive gear A13 and rack A9. The drive motor A12 can drive the upper track 8 to move through the meshing drive gear A13 and rack B11. When the lower track 10 moves, the lower end of the upper track 8 can be locked and fixed to the upper end of the lower track 10. When the lower track 10 moves along the slide groove under the drive of the drive motor A12 until its top end coincides with the bottom end of the upper track 8, the upper track 8 can be locked and fixed when it encounters the lower track 10. Preferably, the upper track 8 and the lower track 10 can be fixed to each other by spring pins. The upper track 8 is provided with a spring positioning pin and a blocking block that can pull the spring pin to compress the spring. The lower track 10 is provided with a corresponding pin hole, thereby realizing the switching between the fixed and sliding connection states of the upper track 8 and the lower track 10.
[0040] In this embodiment, as shown in the appendix Figure 2 Appendix Figure 3 Appendix Figure 4As shown, the recycling mechanism includes a drum 14 rotatably connected to the frame 1. The drum 14 can be used to wind the collection blanket 3. A guide cylinder 15 is arranged parallel to one side of the drum 14. The guide cylinder 15 can guide the movement of the collection blanket 3 when the drum 14 winds the collection blanket 3. The guide cylinder 15 is rotatably connected to the frame 1. The other end of the collection blanket 3 passes around the guide cylinder 15 and is wound around the outer periphery of the drum 14. One end of the drum 14 passes through the frame 1 and is connected to a drive motor B16 fixed on the frame 1. The drive motor can drive the drum 14 to rotate. Mounting plates are also provided at both ends of the drum 14 and the guide cylinder 15. The mounting plates are fixed to the frame 1. The mounting plates can organize and guide the sides of the collection blanket 3 on the drum 14 and the guide cylinder 15 to prevent the collection blanket 3 from deviating when it is wound.
[0041] In this embodiment, as shown in the appendix Figure 2 Appendix Figure 3 Appendix Figure 4 As shown, a rectifier rod 17 is provided between the two collection blankets 3. The bottom of the rectifier rod 17 is fixed to the frame 1. The rectifier rod 17 can straighten the collection blankets 3 when the drum 14 winds and recycles them, so as to avoid the overlapping of the two collection blankets 3 when they touch, which would affect the winding effect of the collection blankets 3 on the drum. A support seat 18 is fixed to the top of the rectifier rod 17. The support seat 18 is rotatably connected to the connecting rod 7 located at the lower end of the track mounting seat 6. The track mounting seat 6 can rotate around the axis of the support seat 18 with the connecting rod 7 at its lower end. The rotation of the track mounting seat 6 can drive the upper track 8 and the lower track 10 to rotate synchronously. The rotation of the upper track 8 and the lower track 10 can raise them to a certain angle so as to better lay the collection blankets 3 on uneven roads.
[0042] In this embodiment, as shown in the appendix Figure 2 Appendix Figure 3 Appendix Figure 4 As shown, a lifting support 19 is fixed on the bracket 2. A lifting arm 20 is slidably connected to the lifting support 19. The lifting arm 20 can slide upward and extend upward.

When the lifting arm 20 slides upward, it can push the connecting rod 7 at the upper end of the track mounting seat 6 to drive the track mounting seat 6 to rotate around the axis of the support seat 18.
[0043] In this embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 As shown, the vibrating mechanism includes a linkage rod 24 rotatably connected to the support 2. The linkage rod 24 extends downward through the support 2 and is hinged at its end to multiple elastic connecting strips 25.

[0044] In this embodiment, as shown in the appendix Figure 1-5 As shown, a collection trough 31 is provided on one side of the guide cylinder 15 of the frame 1. The collection trough 31 can be used to collect the fruits that fall automatically when the collection blanket 3 passes around the guide cylinder 15. A conveyor belt 32 is installed at the bottom of the collection trough 31. The conveyor belt 32 is arranged along the vehicle's travel direction. The conveyor belt 32 can move the fruits in the collection trough 31 along the vehicle's travel direction. A discharge guide plate 33 is fixed at the end of the collection trough 31. A bag hanging rod 34 is symmetrically arranged at one end of the frame 1 near the discharge guide plate 33. A hook 35 is fixed at the end of the bag hanging rod 34. A discharge bag can be hung on the hook 35. The guide plate 33 can guide the fruits conveyed by the conveyor belt 32 into the discharge bag.
[0045] In this embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 7 Appendix Figure 8 As shown, the walking assembly includes a chassis 36 fixed to the top of the frame 1. Multiple walking tracks 37 are provided on the chassis 36. A drive unit 38 is provided inside the walking track 37. The drive unit 38 is electrically connected to the battery module 30 and can drive the walking track 37 to move the chassis 36. The tracked drive method can improve the harvesting robot's passability and adapt to various terrains. A battery box 29 is fixed on the chassis 36. Multiple battery modules 30 are detachably connected inside the battery box 29. Preferably, the side wall of the battery box 29 is provided with a slide rail. The battery module 30 is equipped with a protrusion that matches the slide rail. The battery module 30 and the battery box 29 can also adopt the existing common quick-change structure.
[0046] The working principle of this invention is as follows: Under the remote control of the operator, the chassis 36 of the fruit harvesting equipment moves from between two rows of fruit trees to the side of the fruit tree to be harvested. The vision camera 39 mounted on the frame 1 identifies the canopy of the fruit tree to be harvested and sends the feedback to the control module. The control module estimates the canopy area according to the tree canopy area estimation method. The drive motor A12 drives the drive gear A13, which meshes with the rack B11, to rotate, causing the lower track 10 to extend. When the lower track 10 moves, it will cause the collection blanket 3 to unfold. After the lower track 10 extends to the designated position, the upper track 8 is relatively fixed to the lower track 10. The drive motor A12 drives the drive gear A13, which meshes with the rack B11, to rotate, causing the upper track 8 to extend. The rear end of the lower track 10 is relatively fixed to the front end of the upper track 8. Therefore, the upper track 8 will drive the lower track 10 to extend together. The rack B11 on the lower track 10 disengages from the drive gear A13. Meanwhile, one end of the collecting mat 3 is fixed to the front end of the lower track 10. Therefore, when the upper track 8 and the lower track 10 move, they will drive the collecting mat 3 to unfold. Until the collecting mat 3 is laid, a gap slightly larger than the diameter of the trunk will be left near the base of the fruit tree trunk. The other parts of the collecting mat 3 will automatically close under the action of magnetic materials such as magnetic contact 5 to form a complete collecting mat 3. Rotating the linkage rod 24 will drive the crossbeam 26 to rotate. Adjusting the deflection angle of the crossbeam 26 will cause the electric gripper 28 at the end of the crossbeam 26 to clamp the trunk of the fruit tree or the second and third branches. The vibration motor 27 will generate vibration and transmit the vibration to the top of the fruit tree through the crossbeam 26 and the electric gripper 28, which will vibrate the fruit tree in a continuous manner. The fruit will fall into the collecting mat 3. The vision system will judge the vibration effect from multiple dimensions such as the quantity and duration of fruit, flowers and leaves scattered on the collecting mat 3, and automatically adjust the working parameters of the vibration device according to the pre-set intelligent control target.
[0047] After harvesting, the upper track 8 is retracted first by the drive motor A12, which also drives the lower track 10 to retract together. After the upper track 8 moves into position, the lower track 10 switches to a relative sliding state with the upper track 8. At the same time, the rack B11 of the lower track 10 re-engages with the drive gear A13. The drive motor A12 drives the lower track 10 to retract through the drive gear A13 and the rack B11. The upper track 8 and the lower track 10 collect the blanket 3, which is automatically wound onto the chassis 36 drum 14 by the action of the recovery drum 14. During the recovery process of the collecting blanket 3, the multiple reinforcing ribs arranged on the collecting blanket 3 hold the collecting blanket 3 in place. The fruit is divided into several small sections. In each section, the fruit moves from a lower position to the guide cylinder 15 under the obstruction and movement of the reinforcing ribs. After moving to the highest point of the guide cylinder 15, the fruit falls into the collection trough 31 under its own gravity. The fruit is then transported to the unloading point by a conveyor belt arranged along the vehicle's travel direction. The fruit is automatically loaded into the unloading bag hanging on the bag hanging rod 34. Once the unloading bag is full, it can be removed, and a new unloading bag can be placed on the bag hanging rod 34 to achieve automatic fruit harvesting. The fruit harvesting equipment moves to the next fruit tree to be harvested and repeats the above process, thereby achieving automatic fruit harvesting in the orchard.
[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
