[0043] In the present application, unless otherwise explicitly specified and limited, the terms "connection", "fixation" and the like should be understood in a broad sense, for example, "fixation" can be fixed connection, or detachable connection, or integral; "connection" can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship of two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0044] As shown in Figure 1 , Figure 2 and Figure 3 , the present embodiment provides a pepper picking and cleaning integrated machine, which comprises a rack 1 provided with a walking mechanism 2 at the bottom, a picking device 3 arranged at the front side of the rack 1, a multi-layer cleaning device 5 arranged at the middle of the rack 1, and a pepper collecting device 6 arranged at the rear side of the rack 1.

[0045] The walking mechanism 2 can include a motor, a transmission system and multiple pairs of walking wheels, etc. In a conventional embodiment, reference can be made to an existing agricultural machine equipment with walking function to realize the self-walking function of the overall equipment. Alternatively, in other embodiments, the walking mechanism 2 includes multiple pairs of walking wheels, but without a driving power system, a handrail is arranged on the rack 1, and the grower can use the handrail to realize the movement of the rack 1.

[0046] As shown in Figure 3 and Figure 6 , the picking device 3 comprises at least one pair of picking spiral rods 310 and at least two parallelly arranged conveying belts 320; the conveying belts 320 are arranged obliquely from the lower end to the middle of the rack 1 and can be driven by a motor to convey materials from the lower end to the upper end; a channel is formed between the two adjacent conveying belts 320 for the main stem of the pepper to pass during picking and moving, and a pair of picking spiral rods 310 is arranged in the channel; each pair of picking spiral rods 310 rotates to make the pepper fall off the branch and onto the conveying belt 320.

[0047] Optionally, side baffles 321 are arranged on both sides of the conveying belt 320. The conveying belt 320 is controlled by an independent driving system and can work in coordination with the picking spiral rods 310 to ensure that the picked fruits can be quickly and stably transported to the collection area.

[0048] In the embodiment, each picking screw rod 310 is made of flexible material, and includes an inner rod 311 and at least one outer screw rod 312, for example, two outer screw rods 312 in the embodiment. The outer screw rod 312 is spirally wound on the outer periphery of the inner rod 311 with a gap between the inner rod 311 and the outer screw rod 312, and the ends of the outer screw rod 312 are fixed to the ends of the inner rod 311 respectively. The spiral winding direction of the outer screw rod 312 is consistent with the rotation direction of the picking screw rod 310. In other embodiments, the picking screw rod can also be, for example, an outwardly spirally protruding structure.

[0049] The inner rod 311 is rotatably mounted on the frame of the picking device 3 through a bearing, and the two inner rods 311 in the pair of picking screw rods 310 are driven by a motor to rotate in opposite directions. The outer screw rod 312 rotates with the inner rod 311 to enable the peppers to be separated from the branches of the plants and thrown onto the corresponding conveying belt 320. Figure 2 The left picking screw rod 310 rotates counterclockwise to throw the peppers onto the left conveying belt 320, and the right picking screw rod 310 rotates clockwise to throw the peppers onto the right conveying belt 320.

[0050] In other embodiments, the picking device 3 can include two pairs of picking screw rods 310 and three conveying belts 320, and there are two passages for the main rods of the pepper plants to pass through during the picking process, which can realize the picking of two rows of pepper plants. The inclination angle of the conveying belt 320 can be about 30°.

[0051] The multi-layer cleaning device 5 includes a first cleaning layer 510, a guide plate 520 and a second cleaning layer 530 arranged in sequence from top to bottom. The inlet end of the first cleaning layer 510 is connected to the outlet of the conveying belt 320. The first cleaning layer 510 includes a plurality of first cleaning wheels 512 arranged horizontally in the front-rear direction. The axes of the plurality of first cleaning wheels 512 are perpendicular to the advancing direction. The first cleaning wheels 512 can be driven to rotate in the first direction to clean and convey the peppers, so that the peppers entering the first cleaning layer 510 can fall from the first gap 511 between adjacent first cleaning wheels 512. The size of the first gap 511 is adapted to the maximum size of the picked peppers to allow the peppers to fall and not allow larger branches and leaves to fall. Through the cleaning and transmission of the first cleaning wheels 512 of the first cleaning layer 510, the peppers fall from the first gap 511, and the branches larger than the picked peppers are screened out.

[0052] The guide plate 520 is obliquely arranged below the first cleaning layer 510 to catch the peppers falling from the first cleaning layer 510, and the lower end of the guide plate 520 is located above the inlet end of the second cleaning layer 530.

[0053] Specifically, the guide plate 520 functions as a collection platform, which can effectively catch the peppers falling from the first cleaning layer 510. This ensures that the materials after preliminary screening will not directly fall to the ground or other inappropriate areas, avoiding material loss. By designing the guide plate 520 in an inclined state, the peppers falling on it can automatically slide to the lower end by gravity. This design does not require an additional power source to move the materials, simplifying the device structure and improving processing efficiency.

[0054] The second cleaning layer 530 includes a plurality of second cleaning wheels 532 arranged horizontally along the front-back direction, and the axes of the plurality of second cleaning wheels 532 are perpendicular to the advancing direction. The second cleaning wheels 532 can be driven to rotate in the second direction to clean and convey the peppers. The peppers reaching the second cleaning layer 530 cannot fall from the second gaps 531 between adjacent second cleaning wheels 532. The size of the second gaps 531 is adapted to the size of the picked peppers to prevent the peppers from falling and allow the leaves smaller than the size of the peppers to fall. The discharge end of the second cleaning layer 530 is connected to the pepper collection device 6. The second cleaning layer 530 realizes the screening and discharge of leaves smaller than the size of the peppers.

[0055] The multi-layer cleaning device 5 realizes two cleaning processes, has high cleaning efficiency and low impurity content. The overall structure is relatively simple, easy to process, and has low production cost. Overall, the Z-shaped structure is formed by arranging the guide plate 520 in the multi-layer cleaning device 5, which greatly saves space, miniaturizes the whole machine, and makes the operation control more convenient and compact, which can adapt to different working environments.

[0056] When the pepper picking and cleaning all-in-one machine is working, the whole machine advances forward, and the inclined double helical rods pick the peppers from below the pepper plants, ensuring that the whole plant is within the picking range and improving the picking rate of the peppers. This device not only has high picking efficiency, but also has simple structure, easy processing and production, and low cost. In addition, the double helical rods are made of flexible materials, which reduces the possibility of damage when peeling the peppers, reduces the breakage rate of the pepper fruits, and improves the economic benefits of the pepper fruit picking.

[0057] The mixture of picked peppers, branches, and leaves is received by the conveyor belt 320, and the outer side of the conveyor belt 320 is provided with a side baffle 321 to prevent the peppers from flying out during picking and sliding left and right during conveying. The conveyor belt 320 conveys the pepper mixture to the first cleaning layer 510 of the multi-layer cleaning device 5. The pepper and small branch and leaf mixture after cleaning treatment by the first cleaning layer 510 falls to the guide plate 520, and the large branches and stems that do not meet the requirements are conveyed to the end for discharge.

[0058] The guide plate 520 can guide the pepper mixture treated by the first cleaning layer 510 to the second cleaning layer 530 for secondary cleaning. The small leaves in the pepper mixture with a size smaller than the second gap 531 will fall onto the working ground, while the peppers with a size larger than the second gap 531 will be discharged into the pepper collecting device 6, thereby achieving the tasks of picking, cleaning, and collecting peppers.

[0059] As shown in the drawings, Figure 11 The pepper collecting device 6 in the embodiment includes a box body 610 with an inlet and an outlet 611, a lifting door device 620, and a push plate assembly 630. The inlet is connected to the discharge end of the second cleaning layer 530. The box body 610 has an outlet 611 on one side, and the lifting door device 620 is arranged at the outlet 611. The lifting door device 620 can be driven to control the lifting to open and close the outlet 611. The lifting door device 620 is provided with a lifting door driving device 621 and a door plate 622. The lifting door driving device 621 is arranged on one side of the outlet 611 of the box body 610 and is connected to control the door plate 622. The lifting door driving device 621 can be set according to actual conditions, for example, an electric push rod, a pneumatic cylinder, or a hydraulic cylinder.

[0060] The push plate assembly 630 is arranged in the box body 610 facing the outlet 611. The push plate assembly 630 can move back and forth along the horizontal pushing direction to push the peppers out of the outlet 611.

[0061] When the whole machine returns to the standby area, the pepper unloading work starts. The processed peppers are collected in the pepper collecting device 6. At this time, the lifting door driving device 621 drives the door plate 622 to rise. Then, the push plate driving device 632 drives the push plate assembly 630 to push the peppers in the box body 610 out of the outlet 611 into the packaging bag. The peppers are packaged and processed by manual work, achieving the purpose of collecting peppers.

[0062] Optionally, as shown in the drawings, Figure 11 In the embodiment, the push plate assembly 630 includes a push plate driving device 632 and a push plate 633 vertically arranged in the box body 610. A through slot 634 extending in the horizontal pushing direction is arranged along the bottom of the box body 610. The bottom of the box body 610 refers to the bottom plate of the box body 610 or the part of the side plate of the box body 610 close to the bottom plate.

[0063] The push plate 633 is provided with a connecting piece (not numbered in the figure) matched with the through slot 634; the connecting piece is connected with the push plate driving device 632 through the through slot 634, the push plate driving device 632 comprises a push plate driving motor and a driving pulley set 631, the push plate driving motor drives the driving pulley set 631 to rotate, so as to drive the connecting piece on the push plate 633 to move reciprocatingly along the horizontal moving direction, the push plate driving device 632 applies a horizontal moving pushing force to the push plate 633 in the direction of the outlet 611, so as to push the push plate 633 to move along the through slot 634, and realize the horizontal moving of the push plate 633.

[0064] The height of the through slot 634 is designed to allow the connecting piece to be smoothly connected with the driving pulley set 631 and not to make the collected peppers fall out, and the length of the through slot 634 limits the moving distance of the push plate 633.

[0065] In other embodiments, the push plate assembly 630 comprises a push plate driving device 632 and a push plate 633, the push plate driving device 632 is arranged on the side wall of the box body 610 opposite to the outlet 611, the push plate 633 is arranged perpendicularly to the bottom surface of the box body 610, the center area of the back surface of the push plate 633 is connected with the push plate driving device 632, and the push plate driving device 632 applies a pushing force in the direction of the outlet 611, so as to realize the horizontal moving of the push plate 633 and push the processed peppers out of the outlet 611 from the box body 610.

[0066] In this embodiment, as shown in Figure 9 As shown in Figure 12 The first cleaning wheel 512 is provided with a plurality of rows of first protruding teeth 513 distributed along the axial direction, each row of the first protruding teeth 513 comprises a plurality of split teeth protruding from the surface of the wheel body and arranged along the circumferential direction. The interval between the two adjacent rows of the first protruding teeth 513 on the same first cleaning wheel 512 is the first interval 515.

[0067] The positions of the first protruding teeth 513 on the two adjacent first cleaning wheels 512 are staggered with each other, wherein the position of the first protruding teeth 513 on each first cleaning wheel 512 corresponds to the first interval 515 on the adjacent first cleaning wheel 512, and the size of the first gap 511 can be set as needed, matched with the first protruding teeth 513 to realize the falling of the peppers and the screening of the large branches and leaves. The size of the first interval 515 can be set as needed, allowing the peppers to fall while not allowing the larger branches and leaves to fall, so as to realize the screening of the peppers and the large branches and leaves.

[0068] In this embodiment, the positions of the first teeth 513 on the first cleaning wheel 512 and the corresponding first intervals 515 on adjacent first cleaning wheels 512 are staggered; it can also be described as an alternating fit between the first teeth 513 on the first cleaning wheel 512 and the corresponding first intervals 515 on adjacent first cleaning wheels 512. It can be understood that this alternating fit means that on two adjacent first cleaning wheels 512, the positions of the first teeth 513 on the first cleaning wheel 512 and the first intervals 515 on the other first cleaning wheel 512 are alternately positioned.

[0069] In a preferred embodiment, the free end of the first tooth 513 on each first cleaning wheel 512 can extend into the corresponding first interval 515. When the first cleaning wheel 512 is in operation, the first tooth 513 of one first cleaning wheel 512 can interlacedly pass through the first interval 515 of another first cleaning wheel 512, forming a close and orderly interlaced arrangement with the first tooth 513 of the adjacent first cleaning wheel 512. At this time, the value of the first gap 511 between the outer surfaces of the wheel bodies of two adjacent first cleaning wheels 512 is greater than the highest height d of the first tooth 513, but less than twice the highest height d; wherein, the highest height d of the first tooth 513 is the radial distance from the outer surface of the wheel body to the free end of the tooth. The axial width of the first interval 515 is greater than the axial width of the first tooth 513.

[0070] Optionally, in Figure 9 In the illustrated embodiment, the free ends of the teeth of the first protrusions 513 on the first cleaning wheel 512 do not extend into the corresponding first interval 515; the value of the first gap 511 between the outer surfaces of the wheel bodies of two adjacent first cleaning wheels 512 is greater than twice the maximum height d. The axial width of the first interval 515 can be greater than, equal to, or less than the axial width of the first protrusions 513.

[0071] Optionally, the shape of the first protruding tooth 513 can be set according to the actual situation, and can be, for example, a triangular protruding tooth, a rectangular protruding tooth, a trapezoidal protruding tooth, a circular protruding tooth, a wavy protruding tooth, or even a combination of protruding teeth. In other embodiments, the protruding tooth structure may not be used, and bristles may be set on the first cleaning wheel 512. The bristles replace the protruding teeth to realize the function of discharging branches and leaves, and can handle the chili mixture more gently, reducing damage to the chilies.

[0072] In this embodiment, the free ends of the teeth of the first protruding tooth 513 are inclined toward the rotation direction of the first cleaning wheel 512. For example... Figure 12 and Figure 13As shown, the free ends of the teeth of the first protruding teeth 513 are all inclined towards the rotating direction of the first cleaning wheel 512 in this embodiment, which helps to provide a forward pushing force when the first cleaning wheel 512 is in operation, so as to effectively separate the lighter or smaller impurities from the peppers and push the larger branches to one side, thereby achieving a preliminary cleaning effect.

[0073] In this embodiment, as shown in Figure 10 With Figure 13 As shown, the nearest gap between the outer surfaces of the wheel bodies of the two adjacent second cleaning wheels 532 is the second gap 531. Preferably, the second cleaning wheel 532 is provided with a plurality of rows of second protruding teeth 533 distributed along the axial direction, and each row of second protruding teeth 533 includes a plurality of teeth arranged along the circumferential direction. The interval between the two adjacent rows of second protruding teeth 533 on the same second cleaning wheel 532 is the second interval 536.

[0074] Preferably, the positions of the second protruding teeth 533 on the two adjacent second cleaning wheels 532 are staggered with each other, wherein the position of the second protruding teeth 533 on each second cleaning wheel 532 corresponds to the position of the corresponding second interval 536 on the adjacent second cleaning wheel 532, and the free ends of the teeth of the second protruding teeth 533 on each second cleaning wheel 532 can extend into the corresponding second interval 536 for staggered engagement. The size of the second gap 531 can be set as needed to cooperate with the second protruding teeth to achieve the purpose of falling of small fallen leaves and screening of peppers. The size of the second interval 536 can be set as needed to allow the falling of larger branches while preventing the falling of peppers, thereby achieving the purpose of screening of peppers and small branches.

[0075] It can be understood that the staggered engagement here means that the second protruding teeth 533 of one second cleaning wheel 532 can stagger through the second interval 536 of the other second cleaning wheel 532 when the second cleaning wheel 532 is in operation, and the second protruding teeth 533 of the second cleaning wheel 532 and the second protruding teeth 533 of the adjacent other second cleaning wheel 532 form a close and orderly staggered arrangement.

[0076] In this embodiment, the axial width of the second interval 536 is greater than the axial width of the second protruding teeth 533. The value of the second gap 531 is greater than the maximum height h of the teeth of the second protruding teeth 533 and less than twice the maximum height h, wherein the maximum height h of the teeth of the second protruding teeth 533 is the radial distance from the outer surface of the wheel body to the free end of the tooth.

[0077] In other embodiments, the free ends of the second teeth 533 on each second cleaning wheel 532 do not extend into the corresponding second interval 536; there is only an interlaced correspondence in position. This interlaced correspondence means that on two adjacent second cleaning wheels 532, a ring of second teeth 533 on one second cleaning wheel 532 and the second interval 536 of the other second cleaning wheel 532 are spatially interlaced. The value of the second gap 531 is greater than twice the maximum height h. The axial width of the second interval 536 can be greater than, equal to, or less than the axial width of the second teeth 533.

[0078] The shape of the second protruding tooth 533 can be set according to the actual situation, and can be, for example, a triangular protruding tooth, a rectangular protruding tooth, a trapezoidal protruding tooth, a circular protruding tooth, a wavy protruding tooth, or even a combination of protruding teeth. In one embodiment, the first cleaning wheel 512 and the second cleaning wheel 532 can be the same. Alternatively, in a preferred embodiment, the number of teeth of the second protruding tooth 533 per revolution on the second cleaning wheel 532 is greater than the number of teeth of the first protruding tooth 513 per revolution on the first cleaning wheel 512. This significantly increases the number of times the material to be cleaned comes into contact, thereby enabling finer screening of the material and significantly improving the purity of the cleaned material.

[0079] In another embodiment, the second cleaning wheel 532 may not use a toothed structure. Instead, bristles can be provided on the second cleaning wheel 532. The bristles replace the teeth to remove branches and leaves, which can process the chili mixture more gently and reduce damage to the chilies.

[0080] Optionally, a third comb tooth (not labeled in the figure) is provided on the side plate of the box 610 near the tail end of the second cleaning layer 530. The third comb tooth and the second protrusion tooth 533 of the second cleaning wheel 532 are staggered. The staggering here means that the third comb tooth can extend into the corresponding second interval 536, so as to prevent the chili peppers from leaking out from the gap between the box 610 and the second cleaning wheel 532 when the second cleaning layer 530 discharges the chili peppers into the box 610.

[0081] like Figure 12 and Figure 13 As shown, further, in this embodiment, on the outer surface of the wheel body between two adjacent rings of second protruding teeth 533 on the second cleaning wheel 532 (i.e., at the second interval 536), a plurality of third protruding teeth 534 extending axially are distributed at intervals in the circumferential direction; the plurality of third protruding teeth 534 can be set according to actual conditions, and there can be more than two, specifically three in this embodiment; the height of the second protruding teeth 533 is greater than the height of the third protruding teeth 534.

[0094] The synchronous pulley 820 connected to the first cleaning layer motor 830 is connected to the left end of the first rotating rod 1 via a transmission belt 821 (left and right are based on...). Figure 2 (The orientation shown is used to determine) Synchronous pulley 820 (see...)

[0095] In other embodiments, the plurality of first cleaning wheels 512 correspond to different numbers of first rotating rods 514, and the different numbers of first rotating rods 514 also adopt a transmission mode combining belt transmission and multi-stage transmission.

[0096] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 10 , the second cleaning layer 530 includes a plurality of horizontally spaced second rotating rods 535, which are rotatably mounted on the rack 1 through a pair of bearings.

[0097] Optionally, the number of second rotating rods 535 can be set according to actual conditions, and can be two, three, and more than three, for example, and in the specific embodiment, can be four, for example.

[0098] Specifically, at least one second cleaning wheel 532 is provided on each second rotating rod 535, and a plurality of second rotating rods 535 are connected through a transmission belt 821 to realize synchronous rotation. Specifically, the second cleaning layer 530 includes a plurality of synchronous pulleys 820, a plurality of transmission belts 821, and a second cleaning layer motor 840.

[0099] The second cleaning layer motor 840 is arranged on one side of the rack 1 close to the second cleaning layer 530; each end of the second rotating rod 535 is provided with a synchronous pulley 820; the second rotating rods 535 are connected through the transmission belt 821 to synchronize the synchronous pulleys 820, realizing synchronous transmission; in other embodiments, a tension pulley 822 is also arranged between the two synchronous pulleys 820 connected by the transmission belt 821.

[0100] Specifically, in the present embodiment, the transmission mode of the four second rotating rods also adopts a transmission mode combining belt transmission and multi-stage transmission, to realize long-distance, stable and efficient power transmission, while reducing cost and maintenance difficulty, and improving the reliability and adaptability of the equipment.

[0101] Optionally, in the present embodiment, the second rotating rods 535 are axially fully sleeved with the second cleaning wheels 532, and the pepper mixture introduced through the guide plate 520 is input to the second cleaning layer 530, and the pepper and small branches and leaves are cleaned and processed through the second cleaning wheels 532 axially sleeved with the plurality of second rotating rods 535.

The maximum height of the first protruding tooth 513 is 59 mm, and the axial width of the first protruding tooth 513 is 20 mm. In order to separate the pepper fruits and large branches and leaves, the gap length between adjacent first cleaning wheels 512 is equal to or slightly smaller than the maximum pepper fruit length of the bell pepper. Specifically, in the embodiment, the first gap 511 is 70 mm.

[0103] Optionally, in order to separate the pepper fruits and small branches and leaves, the gap length between adjacent second cleaning wheels 532 is equal to or slightly larger than the minimum pepper fruit length of the bell pepper.

For example, the gap can be changed by manually adjusting the assembly mode of the fixed bracket of the corresponding first rotating rod 514 and second rotating rod 535 or adding or reducing shims, and the gap can be dynamically adjusted by increasing the hydraulic system to control the extension or swing of the fixed bracket of the corresponding first rotating rod 514 and second rotating rod 535.

[0105] Further, in the embodiment, as shown in Figure 7 the first side of the receiving plate 710 is installed on the rack 1 through a first rotating shaft (not numbered in the figure), and the bottom surface of the second side opposite to the first side of the receiving plate 710 abuts against the first cam 720. The first cam 720 is rotatably installed on the rack 1 to drive the receiving plate 710 to perform reciprocating arc motion based on the first rotating shaft. Optionally, the shape of the first cam 720 can be set according to actual conditions, which can be, for example, an elliptical cam, an asymmetric cam, a involute cam, and a cycloid cam.

[0106] Specifically, the first cam 720 is connected and fixed on the discharge rotating rod 721, which is rotatably arranged below the receiving plate 710 on the rack 1. The discharge rotating rod 721 is connected to the receiving cam motor 722 through the transmission belt 821 on the synchronous belt pulley 820. The receiving cam motor 722 outputs power to drive the discharge rotating rod 721 to rotate, thereby driving the first cam 720 to rotate and making the receiving plate 710 move up and down along the trajectory, so as to better discharge the branches and leaves.

[0107] As shown in Figure 14As shown, the upper end of the guide plate 520 is rotatably mounted on the rack 1 through a second rotating shaft, and the lower end of the guide plate 520 abuts against a second cam 521 rotatably mounted on the rack 1, so as to drive the guide plate 520 to perform reciprocating arc motion based on the second rotating shaft. The shape of the second cam 521 can be set according to actual conditions, and can be, for example, an elliptical cam, an asymmetric cam, an involute cam, or a cycloid cam.

[0108] Specifically, the second cam 521 is connected and fixed to a guide rotating rod 522 rotatably arranged on one side of the rack 1 and below the guide plate 520. The guide rotating rod 522 is connected to a guide cam motor 523 through a transmission belt 821 on a synchronous belt pulley 820. The guide cam motor 523 outputs power to drive the guide rotating rod 522, and further drive the second cam 521 to rotate, so that the guide plate 520 periodically rises and falls, collects the pepper mixture processed by the first cleaning layer 510, and enters the second cleaning layer 530 in batches through the vibration of the guide plate 520, while preventing blockage through vibration, further improving the cleaning effect and efficiency.

[0109] Referring to Figure 8 , a pair of guide side plates 526 are further arranged at the middle position of the upper surface of the guide plate 520, so as to correspond to the positions of the first cleaning wheels 512, so that the peppers falling between adjacent first cleaning wheels 512 are shunted through the cooperation of the guide plate 520 and the guide side plates 526, and then fall onto the corresponding second cleaning wheels 532. In addition, a front baffle 524 is further arranged on the rack 1, and a bottom side plate 525 is arranged on the front baffle 524. Figure 3 and Figure 8 It can be known that the front baffle 524 is located at the material inlet end of the second cleaning layer 530, the lower end of the front baffle 524 is bent and inclined backward, the lower end of the front baffle 524 forms a fourth comb tooth capable of being inserted into the corresponding second interval 536 of the frontmost second cleaning wheel 532. When the peppers fall from the guide plate 520, they are blocked by the front baffle 524 and change direction to fall onto the second cleaning wheel 532. The bottom side plate 525 can be coplanarly arranged with the corresponding guide side plate 526 to prevent the peppers from falling from the side of the second cleaning wheel 532.

[0110] As a preferred embodiment of the present application, the picking device 3 further comprises a folding device 4 arranged in a triangular structure with a pointed end facing forward at the front end of the conveying belt 320, for folding the support rods of the peppers to be picked. Through the physical structure design, the pepper branches scattered in the field are folded to the central position, so that the originally widely distributed crops can be more effectively processed in a specific area.

[0111] When the pepper branches are concentrated within a certain range, the picking device 3 can focus more on the operation in this area, reducing unnecessary movement and adjustment time, thereby improving the speed and efficiency of the entire picking process. Optionally, the number of gathering devices 4 can be set according to actual conditions, for example, two, three, and more than three. In the specific embodiment, the number of gathering devices 4 is two.

[0112] The above is only a specific application example of the present application, and does not constitute any limitation on the protection scope of the present application. In addition to the above embodiments, the present application can also have other implementation manners. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
