[0039] In order to better explain the utility model, so as to facilitate understanding, the following will be combined with the specific embodiments of the utility model, make a detailed description.

[0040] It should be noted that, in the embodiments of the utility model, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship between the components, the movement condition, etc. in a certain specific posture (as shown in the drawings), if the specific posture changes, the directional indication also changes accordingly.

[0041] In addition, in the utility model, the description such as "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can be explicitly or implicitly included at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0042] In the utility model, unless otherwise specifically defined and limited, the terms "connection", "fixing" and the like should be understood broadly, for example, "fixing" 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 intermediate medium, can be the internal communication of two elements or the interaction relationship of two elements, unless otherwise specifically limited. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0043] For example, Figures 1 to 3 Especially Figure 8 And Figure 9As shown, the pepper cleaning and collecting assembly provided in the embodiment includes a rack 1 provided with a walking mechanism 2 at the bottom, a multi-layer cleaning device 5 arranged at the middle of the rack 1, and a pepper collecting device 6 arranged at the other side (the rear side in the embodiment) of the rack 1. The front side of the rack 1 corresponds to a pepper input port to be cleaned, which can be the discharge port of a hopper or other structures.

[0044] In a preferred embodiment, the pepper cleaning and collecting assembly can also integrate the picking function, including a picking device 3 arranged at one side (the front side in the embodiment) of the rack 1. The discharge port of the picking device 3 can be the pepper input port to be cleaned, so as to realize the task requirement of directly inputting the picked peppers into the multi-layer cleaning device 5 for cleaning treatment, without the need for additionally matching the picking equipment.

[0045] The walking mechanism 2 can include a motor, a transmission system, and multiple pairs of walking wheels, etc. In a conventional embodiment, the existing agricultural machinery with walking function can be referred to, so as 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 does not have a driving power system. The rack 1 is provided with a handrail, and the grower can realize the movement of the rack 1 by pushing.

[0046] As shown, Figure 3 As shown, Figure 6 The picking device 3 includes 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 the motor to convey the materials from the lower end to the upper end. The channel formed between the two adjacent conveying belts 320 is used for the main stem of the pepper to pass through during the picking process, and a pair of picking spiral rods 310 is arranged in the channel. Each pair of picking spiral rods 310 rotates to make the peppers fall off the branches and onto the conveying belts 320.

[0047] Optionally, side baffles 321 are arranged on both sides of the conveying belts 320. The conveying belts 320 are controlled by an independent driving system and can work in coordination with the picking spiral rods 310, so as to ensure that the picked fruits can be quickly and stably transported to the collecting 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 to rotate in opposite directions by a motor, and the outer screw rod 312 rotates with the inner rod 311, so that the peppers can be separated from the branches of the plants and thrown onto the corresponding conveying belt 320. Referring to Figure 2 , the left picking screw rod 310 rotates counterclockwise to throw the peppers to the left conveying belt 320, and the right picking screw rod 310 rotates clockwise to throw the peppers to 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 picking, so that two rows of pepper plants can be picked. The inclination angle of the conveying belt 320 can be about 30°.

[0051] Referring to Figure 8 and Figure 9 , 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 input port of the peppers to be cleaned (when the picking device 3 is provided, the outlet port of the conveying belt 320 is connected). 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 forward 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 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 be able to catch the peppers falling from the first cleaning layer 510, and the lower end of the guide plate 520 is located above the feeding end of the second cleaning layer 530.

[0053] Specifically, the guide plate 520 functions as a collection platform to 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 equipment structure and improving processing efficiency.

[0054] The second cleaning layer 530 includes a plurality of second cleaning wheels 532 arranged horizontally and spaced apart in the front-rear direction, 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 based on the second direction to clean and convey the peppers, and the peppers reaching the second cleaning layer 530 cannot fall from the second gaps 531 between adjacent second cleaning wheels 532. Among them, the size of the second gap 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 collecting 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 twice cleaning, has high cleaning efficiency and low impurity content. The overall structure is relatively simple, easy to process, and has low production cost. Overall, the guide plate 520 arranged in the multi-layer cleaning device 5 forms a Z-shaped structure, greatly saving space, making the whole machine small, and making operation control more convenient and small, which can adapt to different working environments.

[0056] When the pepper cleaning and collecting assembly with the pepper picking device 3 is working, the whole machine advances obliquely, and the double helical rods pick 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. Secondly, the double helical rods are made of flexible materials, reducing the possibility of damage when peeling the peppers, reducing the damage rate of the pepper fruits, and improving the economic benefits of the pepper fruit picking.

[0057] The mixture of picked peppers, branches and leaves is received by the conveying belt 320, and the outer side of the conveying 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 conveying 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 the first cleaning layer 510 cleaning treatment falls to the guide plate 520, and the large branches are conveyed to the end and discharged.

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

[0059] As shown in Figure 12 , 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 is provided with 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 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 is started. 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. Manual packaging and subsequent work processing are performed to achieve the purpose of collecting peppers.

[0062] Optionally, as shown in Figure 12 , 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 includes 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 reciprocate along the horizontal pushing direction, the push plate driving device 632 applies a horizontal 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 pushing 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 pushing distance of the push plate 633.

[0065] In other embodiments, the push plate assembly 630 includes 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 perpendicular 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 pushing 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 10 As shown in Figure 13 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 first protruding teeth 513 includes 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 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 to allow 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 10 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 13 and Figure 14As shown, further, in this embodiment, the free ends of the teeth of the first protrusion 513 are all inclined toward the rotation direction of the first cleaning wheel 512; this helps to provide a forward propulsion force when the first cleaning wheel 512 is operating, which can effectively separate lighter or smaller impurities from the chili peppers and push larger branches to one side, thereby achieving a preliminary cleaning effect.

[0073] In this embodiment, as Figure 11 and Figure 14 As shown, the closest gap between the outer surfaces of two adjacent second cleaning wheels 532 is the second gap 531. Preferably, the second cleaning wheel 532 is provided with multiple rings of second protruding teeth 533 distributed axially, each ring of second protruding teeth 533 including multiple circumferentially spaced sub-teeth. The interval between two adjacent rings of second protruding teeth 533 on the same second cleaning wheel 532 is the second gap 536.

[0074] Preferably, the positions of the second protrusions 533 on two adjacent second cleaning wheels 532 are staggered, wherein the position of the second protrusion 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 end of the teeth of the second protrusion 533 on each second cleaning wheel 532 can extend into the corresponding second interval 536 for staggered meshing. The size of the second gap 531 can be set as needed, in conjunction with the second protrusions, to achieve the purpose of removing small fallen leaves and screening chili peppers. The size of the second interval 536 can be set as needed, allowing larger branches and leaves to fall while preventing chili peppers from falling, thus achieving the purpose of screening chili peppers and small branches and leaves.

[0075] It is understandable that the interleaved meshing here means that when the second cleaning wheel 532 is operating, the second teeth 533 of one second cleaning wheel 532 can interleave through the second interval 536 of another second cleaning wheel 532, and the second teeth 533 of the second cleaning wheel 532 and the second teeth 533 of the adjacent second cleaning wheel 532 form a close and orderly interleaved arrangement.

[0076] In this embodiment, the axial width of the second gap 536 is greater than the axial width of the second tooth 533. The value of the second gap 531 is greater than the highest tooth height h of the second tooth 533, but less than twice the highest height h; wherein, the highest tooth height h of the second tooth 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.

[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 folding devices 4 can be set according to actual conditions, for example, two, three, and more than three. In the specific embodiment, the number of folding devices 4 is two.
