[0013] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] like Figure 1 and Figure 2 As shown, the adaptive fruit harvesting device for avoiding rigid contact comprises a combing and brushing unit 2 and a vibration unit 1, and the vibration unit 1 is detachably connected to the combing and brushing unit 2.

[0015] like Figures 3 to 6As shown, the brush unit 2 includes a plate-shaped brush base plate 21, and a plurality of parallel base plate guide rails 211 are provided on the inner wall of the brush base plate 21, and a plurality of movable brush rod assemblies 20 are provided between the base plate guide rails 211. The left and right edges of the inner wall of the brush base plate 21 are provided with slot plate guide rails 28, and a movable slot plate 26 is provided between the slot plate guide rails 28. The slot plate 26 is provided with a plurality of penetrating adjustment long grooves 261, and the adjustment long grooves 261 cooperate with the brush rod assemblies 20 and adjust the spacing of the brush rod assemblies 20. A plurality of push plate joints 25 and a push rod frame 24 are provided on the distal side wall of the slot plate 26. A pair of fixed seats 22 are provided on the outer wall of the brush base plate 21, and a hydraulic cylinder 23 is provided between the fixed seats 22. The movable shaft of the hydraulic cylinder 23 is fixedly connected to the push rod frame 24, and a plurality of first connecting screw holes 210 are provided in the middle of the outer wall of the brush base plate 21.

[0016] like Figures 7 to 9 As shown, the brush rod assembly 20 includes a main cross bar 29 in the shape of a long strip, a limiting rod 291 is provided at the end of the upper side wall of the main cross bar 29, a plurality of detachable brush bases 208 are provided on the upper side wall of the main cross bar 29, a rubber base 206 is provided in the brush base 208, a rod body seat 203 is provided in the rubber base 206, a brush rod 201 is provided on the rod body seat 203, a top nut 202 is provided on the top of the rod body seat 203, a spring 207 is sleeved on the tail shaft section of the brush rod 201, a plurality of sliding seats 292 are provided on the lower side wall of the main cross bar 29, and the sliding seats 292 cooperate with the bottom plate guide rail 211.

[0017] One end of the spring 207 rests against the shoulder of the combing brush rod 201, and the other end of the spring 207 rests against the shoulder of the rod body seat 203. The rod body seat 203 is installed in the rubber base 206 through an elastic gasket 205. A bottom nut 204 is provided on the top of the combing brush base 208, and the bottom nut 204 constrains the rubber base 206 in the combing brush base 208.

[0018] It should be noted that the diameter of the shaft section at the tail of the brush rod 201 is smaller than the diameter of the through hole at the bottom of the rod body seat 203. Under the action of a large axial external force, the brush rod 201 can be extended and slid in the rod body seat 203 through the spring 207. The diameter of the middle inner hole of the top nut 202 is larger than the diameter of the shaft section at the front of the brush rod 201, which constrains the brush rod 201 to extend to the left without affecting the extension of the brush rod 201, so that it will not slide out of the rod body seat 203.

[0019] like Fig.10 and Fig.11As shown, the vibration unit 1 comprises a plate-shaped base 15, an outer wall of the base 15 is provided with a mounting frame 18 and a motor base 17, a hydraulic motor 171 is provided on the motor base 17, an output shaft of the hydraulic motor 171 is provided with a crank wheel 16, an inner wall of the base 15 is provided with a pair of parallel guide rails 13, a slidable slide seat 11 is provided between the guide rails 13, a plurality of second connection screw holes 111 are provided on the slide seat 11, and the second connection screw holes 111 are connected to the first connection screw holes 111. The hole 210 is connected by screws, and an eccentric shaft 161 is provided on the crank wheel 16. A connecting rod 14 is provided on the eccentric shaft 161. The other end of the connecting rod 14 is hinged to the connecting rod 12. A pair of sliders 19 and a connecting block 191 are provided on the outer wall of the slide seat 11. A penetrating connecting block hole 192 is provided on the connecting block 191. The slider 19 cooperates with the guide rail 13. The end of the connecting rod 12 penetrates the connecting block hole 192 and is fixedly connected to the connecting block 191.

[0020] It should be noted that the mounting bracket 18 can be connected to an external mechanical device, such as the hydraulic arm 3 .

[0021] The working principle of the vibration unit 1 is described below.

[0022] like Fig.10 As shown, when the hydraulic motor 171 is started, the crank wheel 16 drives the connecting rod 14 through the eccentric shaft 161, and the connecting rod 14 drives the connecting block 191, so that the slide 11 starts to slide back and forth on the guide rail 13. Since the slide 11 is fixedly connected to the combing and brushing bottom plate 21, the combing and brushing bottom plate 21 starts to vibrate back and forth.

[0023] The working principle of the brush unit 2 is described below.

[0024] like Fig.13 As shown, when the vibration unit 1 starts to work, the brush bar 201 of the brush bar assembly 20 of the brush base plate 21 starts to vibrate and comes into contact with the fruits of the target tree 4, causing the fruits to fall.

[0025] It should be noted that when the brush bar 201 is subjected to a large radial external force, the rubber base 206 is deformed, so that the rod body seat 203 can swing the brush bar 201 to a certain extent. In addition, when the brush bar 201 is subjected to a large external force, it can generate a certain amount of expansion and contraction and swing, thereby avoiding damage to the fruit tree caused by rigid contact with the branches, and realizing adaptive brush vibration.

[0026] When it is necessary to adjust the spacing of the combing brush rod assembly 20, the hydraulic cylinder 23 can be started, and the hydraulic cylinder 23 drives the push rod frame 24, the push plate joint 25 and the slot plate 26 to move synchronously, so that the adjustment long groove 261 on the slot plate 26 begins to squeeze the limit rod 291, causing the combing brush rod assembly 20 to start sliding along the bottom plate guide rail 211, thereby making the spacing of the combing brush rod assembly 20 larger or smaller, adapting to the harvesting needs of different fruit trees and fruit varieties, and increasing the adaptability and flexibility of the equipment.

[0027] The adaptive fruit harvesting device that avoids rigid contact realizes the adaptive extension and swinging functions of the combing and brushing rod through a hydraulic system and elastic structure design. The combing and brushing rod can be automatically adjusted according to the shape of the fruit tree branches and the distribution of the fruits, effectively reducing the damage to the fruit trees and fruits caused by rigid contact.

[0028] Obviously, the embodiments described above are only part of the embodiments of the present application, rather than all the embodiments. The drawings provide preferred embodiments of the present application, but do not limit the patent scope of the present application.
