Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0043] In the present invention, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral body; "connection" can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] As Figure 1 , Figure 2 and Figure 3 shown, in this embodiment, a chili picking and cleaning integrated machine is provided, which includes: a frame 1 provided with a traveling mechanism 2 at the bottom, a picking device 3 provided at the front side of the frame 1, a multi-layer cleaning device 5 provided in the middle of the frame 1, and a chili collecting device 6 provided at the rear side of the frame 1.

[0045] The traveling mechanism 2 can include a motor, a transmission system, multiple pairs of traveling wheels, etc. In a conventional implementation, reference can be made to existing agricultural machinery with traveling functions to achieve the self-traveling function of the overall device. Alternatively, in other embodiments, the traveling mechanism 2 includes multiple pairs of traveling wheels, but there is no power system for driving the travel, and a hand-pushing armrest is provided on the frame 1, and the grower can use the hand-pushing method to move the frame 1.

[0046] As Figure 3 and Figure 6 shown, the picking device 3 includes at least one pair of picking spiral rods 310 and at least two conveyor belts 320 arranged side by side; the conveyor belts 320 are arranged obliquely from the front end of the frame 1 to the middle of the frame 1 from bottom to top and can be driven by a motor to convey materials from bottom to top; a passage for the main stem of the chili to pass through during the picking process is formed between two adjacent conveyor belts 320, and a pair of picking spiral rods 310 are provided in the passage; each pair of picking spiral rods 310 rotates to make the chili break away from the branches and fall onto the conveyor belt 320.

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

[0048] Among them, in this embodiment, each picking screw rod 310 can be made of a flexible material. The picking screw rod 310 includes an inner rod 311 and at least one outer screw rod 312. For example, in this factual example, the number of outer screw rods 312 is two. The outer screw rods 312 are spirally wound around the outer periphery of the inner rod 311 and have a gap with the inner rod 311. The end portions of the outer screw rods 312 are respectively fixed to the end portions of the inner rod 311; the spiral winding direction of the outer screw rods 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 outward spiral protrusion.

[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 a pair of picking screw rods 310 are driven by a motor to rotate in opposite directions to each other. The outer screw rods 312 rotate along with the inner rod 311 so as to be able to separate the peppers from the branches of the plant and throw them onto the corresponding conveyor belt 320. Refer to Figure 2 , the picking screw rod 310 on the left rotates counterclockwise to throw the peppers onto the conveyor belt 320 on the left, while the picking screw rod 310 on the right rotates clockwise to throw the peppers onto the conveyor belt 320 on the right.

[0050] In other embodiments, the picking device 3 can include two pairs of picking screw rods 310 and three conveyor belts 320. There are two channels for the main stems of the pepper plants to pass through during the picking process, and the picking of two rows of pepper plants can be realized. Among them, the inclination angle of the conveyor 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 that are sequentially arranged at intervals from top to bottom; among them, the feeding end of the first cleaning layer 510 is connected to the discharging port of the conveyor belt 320. The first cleaning layer 510 includes a plurality of first cleaning wheels 512 that are horizontally spaced along the front-rear direction. The axes of the plurality of first cleaning wheels 512 are all perpendicular to the advancing direction. The first cleaning wheels 512 can be driven to rotate based on the first direction to clean and convey the peppers, so as to realize that the peppers entering the first cleaning layer 510 can fall from the first gap 511 between adjacent first cleaning wheels 512. Among them, the interval 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 transfer of the first cleaning wheels 512 of the first cleaning layer 510, the peppers fall from the first gap 511, and the branch blocks larger than the picked peppers are screened out.

[0052] The guide plate 520 is inclinedly 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 and can effectively catch the peppers that fall from the first cleaning layer 510. This ensures that the materials after preliminary screening do not directly fall to the ground or other inappropriate areas, avoiding material loss. By designing the guide plate 520 to be in an inclined state, the peppers that fall on it can automatically slide towards the lower end by means of gravity. This design does not require an additional power source to move the materials, simplifies the equipment structure, and improves the processing efficiency at the same time.

[0054] The second cleaning layer 530 includes a plurality of second cleaning wheels 532 horizontally spaced along the front-rear direction. The axes of the plurality of second cleaning wheels 532 are all 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. The peppers that reach the second cleaning layer 530 cannot fall through the second gap 531 between adjacent second cleaning wheels 532. Among them, the interval size of the second gap 531 is adapted to the size of the picked peppers to prevent the peppers from falling and allow the branches and 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 is used to screen and discharge the leaves smaller than the size of the peppers.

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

[0056] When the pepper picking and cleaning integrated machine is operating, the double spiral rods that tilt forward as a whole pick peppers from below the pepper plants upwards to ensure that the whole plant is within the picking range and improve the pepper picking rate. This device not only has a high picking efficiency, but also has a simple structure, is easy to process and produce, and has a low cost. Secondly, using flexible materials to make the double spiral rods reduces the possibility of damage caused when peeling the peppers, reduces the damage rate of pepper fruits, and improves the economic benefits of pepper fruit picking.

[0057] The mixture of picked peppers, branches, and leaves is received by the conveyor belt 320. Side baffles 321 are provided on the outer sides of the conveyor belt 320 to prevent the peppers from flying out during the picking process and slipping to the left and right during the conveying process; the conveyor belt 320 conveys the pepper mixture to the first cleaning layer 510 of the multi-layer cleaning device 5. The mixture of peppers and small branches and leaves after being cleaned by the first cleaning layer 510 falls onto the guide plate 520, and the unqualified large branches are conveyed to the end for discharge.

[0058] The guide plate 520 can collect and guide the pepper mixture processed by the first cleaning layer 510 to the second cleaning layer 530 for the second cleaning. The small leaves in the pepper mixture with a size smaller than the second gap 531 are set to fall onto the working ground, while the peppers with a size larger than the second gap 531 are set to be discharged into the pepper collection device 6, thus realizing multiple tasks such as pepper picking, cleaning, and collection.

[0059] As Figure 11 shown, in this embodiment, the pepper collection device 6 includes: a box body 610 having 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. An outlet 611 is provided on one side of the box body 610, and the lifting door device 620 is arranged at the outlet 611. The lifting door device 620 can be driven to control its lifting to realize the opening and closing of the outlet 611. Among them, the lifting door device 620 is provided with a lifting door driving device 621 and a door panel 622. The lifting door driving device is arranged on one side of the outlet 611 of the box body 610 and is connected to control the door panel 622. The lifting door driving device 621 can be set according to the actual situation, for example, it can be an electric push rod, a 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 reciprocate along the horizontal pushing direction to push the peppers out of the outlet 611.

[0061] When the whole machine returns to the pending area, the pepper unloading work starts. The processed peppers are all collected in the pepper collection device 6. At this time, the lifting door driving device 621 drives the door panel 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 packing bag, and the manual packing and subsequent work processing are carried out to achieve the purpose of pepper collection.

[0062] Optionally, as Figure 11 shown, in this embodiment, the push plate assembly 630 includes a push plate driving device 632 and a push plate 633 erected in the box body 610. A through slot 634 extending along the horizontal pushing direction is provided along the bottom of the box body 610. Among them, the bottom of the box body 610 refers to the bottom plate of the box body 610 or the place near the bottom plate of the side plate of the box body 610.

[0063] The push plate 633 is provided with a connecting member (not labeled in the figure) that cooperates with the through slot 634; the connecting member passes through the through slot 634 and is connected to the push plate driving device 632. 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 member 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, so as to realize the horizontal pushing of the push plate 633.

[0064] Among them, the height design standard of the through slot 634 is that it allows the connecting member to be smoothly connected to the driving pulley set 631 and does not allow the collected peppers to fall out. 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 central area of the back surface of the push plate 633 is connected to the push plate driving device 632. 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 realize pushing the processed peppers out of the outlet 611 from the box body 610.

[0066] In this embodiment, as Figure 9 and Figure 12 shown, the closest gap between the outer surfaces of the wheel bodies of two adjacent first cleaning wheels 512 is the first gap 511. The first cleaning wheel 512 is provided with multiple circles of first protrusions 513 that are axially spaced apart. Each circle of first protrusions 513 includes multiple sub-teeth that protrude from the surface of the wheel body and are circumferentially spaced apart. The interval between two adjacent circles of first protrusions 513 on the same first cleaning wheel 512 is the first interval 515.

[0067] The positions of the first protrusions 513 on two adjacent first cleaning wheels 512 are arranged in an interleaved manner. Among them, the positions of the first protrusions 513 on each first cleaning wheel 512 correspond to the first intervals 515 on the adjacent first cleaning wheel 512. The size of the first gap 511 can be set as needed, and it is used to cooperate with the first protrusions 513 to realize the dropping of peppers and the screening of large branches and leaves. The size of the first interval 515 can be set as needed, allowing peppers to fall while not allowing larger branches and leaves to fall, so as to realize the screening of peppers and large branches and leaves.

[0068] In this embodiment, the positions of a circle of first protrusions 513 on the first cleaning wheel 512 are arranged in an interleaved manner with the positions of corresponding first intervals 515 on the adjacent first cleaning wheel 512; it can also be stated that there is an interleaved fit between a circle of first protrusions 513 on the first cleaning wheel 512 and the corresponding first intervals 515 on the adjacent first cleaning wheel 512. It can be understood that the interleaved fit here means the interleaved corresponding relationship between a circle of first protrusions 513 on the first cleaning wheel 512 and the first intervals 515 of another first cleaning wheel 512 on two adjacent first cleaning wheels 512.

[0069] In a preferred embodiment, the free ends of the teeth of the first protrusions 513 on each first cleaning wheel 512 can extend into the corresponding first intervals 515. When the first cleaning wheel 512 operates, the first protrusions 513 of one first cleaning wheel 512 can pass through the first intervals 515 of another first cleaning wheel 512 in an interleaved manner, and the first protrusions 513 of the first cleaning wheel 512 and the first protrusions 513 of another adjacent first cleaning wheel 512 form a tight and orderly interleaved arrangement state. 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 maximum height d of the teeth of the first protrusions 513 and less than twice the maximum height d; wherein, the maximum height d of the teeth of the first protrusions 513 is the radial distance from the teeth of the first protrusions 513 on the outer surface of the wheel body to the free ends of the teeth. The axial width of the first interval 515 is greater than the axial width of the first protrusions 513.

[0070] Optionally, in Figure 9 In the shown 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 intervals 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 protrusions 513 can be set according to actual conditions, and can be, for example, triangular protrusions, rectangular protrusions, trapezoidal protrusions, circular protrusions, wavy protrusions, or even combined protrusions. In other embodiments, the protrusion structure can also not be used, and bristles can be provided on the first cleaning wheel 512. The bristles replace the protrusions to achieve the function of discharging branches and leaves, and can handle the pepper mixture more gently, reducing the damage to the peppers.

[0072] In this embodiment, the free ends of the teeth of the first protrusions 513 are inclined towards the rotation direction of the first cleaning wheel 512. As Figure 12 and Figure 13As shown, furthermore, in this embodiment, the free ends of the teeth of the first protrusions 513 are all inclined towards the rotation direction of the first cleaning wheel 512; this helps to provide a forward propulsion force when the first cleaning wheel 512 operates, which can effectively separate lighter or smaller impurities from the peppers and push the larger branches to one side, thus achieving a preliminary cleaning effect.

[0073] In this embodiment, as Figure 10 with Figure 13 shown, the closest gap between the outer surfaces of the adjacent two second cleaning wheels 532 is the second gap 531. Preferably, the second cleaning wheels 532 are provided with multiple circles of second protrusions 533 spaced axially, and each circle of second protrusions 533 includes multiple teeth spaced circumferentially. The interval between two adjacent circles of second protrusions 533 on the same second cleaning wheel 532 is the second interval 536.

[0074] Preferably, the positions of the second protrusions 533 on the adjacent two second cleaning wheels 532 are arranged in a staggered manner. Among them, the positions of the second protrusions 533 on each second cleaning wheel 532 correspond to the positions of the corresponding second intervals 536 on the adjacent second cleaning wheel 532, and the free ends of the teeth of the second protrusions 533 on each second cleaning wheel 532 can extend into the corresponding second intervals 536 for staggered engagement. The size of the second gap 531 can be set as needed, and it is used in cooperation with the second protrusions to achieve the purpose of dropping small fallen leaves and screening peppers. The size of the second interval 536 can be set as needed, allowing larger branches and leaves to drop while not allowing peppers to drop, achieving the purpose of screening peppers and small branches and leaves.

[0075] It can be understood that the meaning of the staggered engagement here is that when the second cleaning wheel 532 operates, the second protrusions 533 of one second cleaning wheel 532 can stagger through the second intervals 536 of another second cleaning wheel 532, and the second protrusions 533 of the second cleaning wheel 532 and the second protrusions 533 of the adjacent other second cleaning wheel 532 form a tight and orderly staggered arrangement state.

[0076] In this embodiment, the axial width of the second interval 536 is greater than the axial width of the second protrusion 533. The value of the second gap 531 is greater than the maximum height h of the teeth of the second protrusion 533 and less than twice the maximum height h; wherein, the maximum height h of the teeth of the second protrusion 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 spaced teeth of the second teeth 533 on each second cleaning wheel 532 do not extend into the corresponding second spaces 536, and there is only an interleaved corresponding relationship in terms of position. It can be understood that the interleaved corresponding relationship means that on two adjacent second cleaning wheels 532, a circle of second teeth 533 on one second cleaning wheel 532 and the second spaces 536 of the other second cleaning wheel 532 present an interleaved corresponding relationship in terms of spatial position. Among them, the value of the second gap 531 is greater than twice the maximum height h. The axial width of the second space 536 can be greater than, equal to, or less than the axial width of the second teeth 533.

[0078] The shape of the second teeth 533 can be set according to the actual situation, and can be, for example, triangular teeth, rectangular teeth, trapezoidal teeth, circular teeth, wavy teeth or even combined teeth. In one embodiment, the first cleaning wheel 512 and the second cleaning wheel 532 can be the same. Or, in a preferred embodiment, the number of spaced teeth of each circle of second teeth 533 on the second cleaning wheel 532 is more than the number of spaced teeth of each circle of first teeth 513 on the first cleaning wheel 512, so that the number of contacts with the material to be cleaned is greatly increased, thereby enabling finer screening of the material and significantly improving the purity of the material after cleaning.

[0079] In another embodiment, the second cleaning wheel 532 can also not use a tooth structure, but instead bristles are provided on the second cleaning wheel 532, and the bristles replace the teeth to achieve the function of discharging branches and leaves, and can handle the pepper mixture more gently, reducing the damage to the peppers.

[0080] Optionally, a third comb tooth (not labeled in the figure) is provided on the side plate of the box body 610 close to the tail end of the second cleaning layer 530, and the third comb tooth and the second teeth 533 of the second cleaning wheel 532 are arranged in an interleaved manner. Here, the interleaving means that the third comb tooth can extend into the corresponding second space 536 to prevent peppers from leaking out through the gap between the box body 610 and the second cleaning wheel 532 when the second cleaning layer 530 discharges peppers into the box body 610.

[0081] As Figure 12 and Figure 13 shown, further, in this embodiment, on the outer surface of the wheel body (i.e., at the second space 536) between two adjacent circles of second teeth 533 on the second cleaning wheel 532, a plurality of third teeth 534 extending axially are distributed at intervals in the circumferential direction; the plurality of third teeth 534 can be set according to the actual situation and can be more than two. Specifically, there are three in this embodiment; the height of the second teeth 533 is greater than the height of the third teeth 534. The design of the height difference allows the device to perform more detailed screening according to the different sizes and weights of the materials.

[0082] Specifically, in other embodiments, the height of the second protrusion 533 is 26 mm, and the height of the third protrusion 534 is 10 mm.

[0083] Optionally, in this embodiment, the first direction and the second direction are the same direction (both are clockwise directions based on Figure 3 , and the first cleaning layer 510, the guide plate 520, and the second cleaning layer 530 are arranged in a Z-shape from top to bottom. Further optimize the spatial layout to achieve a compact structure setting.

[0084] As a preferred embodiment of the present invention, a plurality of partition plates 330 are arranged at intervals along the conveying direction of the conveyor belt 320 on the conveying surface of the conveyor belt 320. The partition plates 330 can prevent the peppers from slipping during the upward conveying process.

[0085] Optionally, as Figure 2 shown in Figure 6 , a plurality of first comb teeth 331 are arranged at intervals at the free ends of each partition plate 330, and the positions of the first comb teeth 331 are arranged in an interleaved manner with the positions of the first protrusions 513 on the first cleaning wheel 512 closest to the conveyor belt 320. Here, the interleaving means that the first comb teeth 331 can extend into the corresponding first intervals 515.

[0086] It can be understood that during the operation of the conveyor belt 320, the plurality of first comb teeth 331 arranged at intervals can pass through the first intervals 515 of the first cleaning wheel 512, and the picked pepper mixture can be smoothly conveyed to the multi-layer cleaning device 5.

[0087] Furthermore, in this embodiment, the pepper picking and cleaning integrated machine further includes a discharging device 7, and the discharging device 7 is connected to the discharging end of the first cleaning layer 510; the discharging device 7 includes a receiving plate 710, and the branches are discharged onto the receiving plate 710 by the first cleaning wheel 512 and fall onto the picking land under the action of the discharging device 7.

[0088] Optionally, in this embodiment, a plurality of second comb teeth are arranged at intervals on the first side of the receiving plate 710 close to the first cleaning wheel 512. The second comb teeth are not shown in the figure, and the second comb teeth can be arranged in an interleaved manner with the positions of the first protrusions 513. Here, the interleaving means that the second comb teeth can extend into the corresponding first intervals 515. During the operation, the first protrusions 513 of the first cleaning wheel 512 can pass through the intervals between the second comb teeth.

[0089] As Figure 3 , Figure 4 , Figure 5 and Figure 9As shown, preferably, the first cleaning layer 510 includes a plurality of first rotating rods 514 horizontally spaced along the front-rear direction. The first rotating rods 514 are rotatably mounted on the frame 1 through a pair of bearings. The number of the first rotating rods 514 can be set according to actual conditions, such as two, three or more than three. In this specific embodiment, for example, it is three.

[0090] At least one first cleaning wheel 512 corresponding to the conveyor belt 320 is provided on each first rotating rod 514. In this embodiment, since there are two conveyor belts 320, two first cleaning wheels 512 are provided on each first rotating rod 514. The first cleaning wheels 512 on the first rotating rod 514 located behind the transmission direction of the conveyor belt 320 form a pepper transmission channel. Baffles are provided on both sides of the pepper transmission channel to prevent the material from splashing and escaping, and to limit the lateral movement of the material, forcing the material to flow uniformly along the axial direction of the cleaning wheel, avoiding local accumulation or short circuit, and improving the processing capacity per unit time.

[0091] The plurality of first rotating rods 514 are connected by a transmission belt 821 to achieve transmission and synchronous rotation. Specifically, the first cleaning layer 510 includes a plurality of synchronous belt pulleys 820, a plurality of transmission belts 821 and a first cleaning layer motor 830.

[0092] The first cleaning layer motor 830 is arranged on one side of the frame 1 near the first cleaning layer 510. A synchronous belt pulley 820 is provided at each end of the first rotating rod 514. The first rotating rods 514 are connected by a transmission belt 821 to the synchronous belt pulleys 820 to achieve synchronous transmission. In other embodiments, a tension pulley 822 is further provided between two synchronous belt pulleys 820 connected by a transmission belt 821.

[0093] Specifically, in this embodiment, the transmission method of the three first rotating rods 514 is as follows. The three first rotating rods 514 are numbered as the 1st first rotating rod, the 2nd first rotating rod and the 3rd first rotating rod from front to back.

[0094] The synchronous belt pulley 820 connected to the first cleaning layer motor 830 is connected by a transmission belt 821 to the synchronous belt pulley 820 at the left end of the 1st first rotating rod (the left and right are determined based on Figure 2 the shown orientation) (see Figure 5 ), to achieve connection and transmission. The synchronous belt pulley 820 at the right end of the 1st first rotating rod is connected by a transmission belt 821 to the synchronous belt pulley 820 on the right side of the 2nd first rotating rod to achieve connection and transmission. The left end of the 2nd first rotating rod is then connected by a transmission belt 821 to the 3rd first rotating rod to achieve connection and rotation. The first cleaning layer 510 realizes the power transmission and synchronous control from the first cleaning layer motor 830 to the plurality of first rotating rods 514 through a combination of belt transmission and multi-stage transmission.

[0095] In other embodiments, different numbers of first rotating rods 514 are correspondingly provided for multiple first cleaning wheels 512, and a transmission mode combining belt transmission and multi-stage transmission is also adopted between the different numbers of first rotating rods 514.

[0096] Such as Figure 3 、 Figure 4 、 Figure 5 and Figure 10 As shown, the second cleaning layer 530 includes multiple second rotating rods 535 arranged at horizontal intervals, and the second rotating rods 535 are rotatably mounted on the frame 1 through paired bearings.

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

[0098] Specifically, at least one second cleaning wheel 532 is arranged on each second rotating rod 535, and the multiple second rotating rods 535 are connected by a transmission belt 821 to achieve transmission and synchronous rotation. Specifically, the second cleaning layer 530 includes multiple synchronous belt wheels 820, multiple transmission belts 821 and a second cleaning layer motor 840.

[0099] The second cleaning layer motor 840 is arranged on one side of the frame 1 close to the second cleaning layer 530; a synchronous belt wheel 820 is provided at each end of the second rotating rod 535; the second rotating rods 535 are connected by a transmission belt 821 to the synchronous belt wheels 820 to achieve synchronous transmission; in other embodiments, a tension pulley 822 is further arranged between two synchronous belt wheels 820 connected by a transmission belt 821.

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

[0101] Optionally, in this embodiment, the second cleaning wheels 532 are fully sleeved on the second rotating rods 535 axially, 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 through the second cleaning wheels 532 fully sleeved on the multiple second rotating rods 535 axially.

[0102] Optionally, the length of the pepper fruit of the chili pepper is 35 to 70 mm, and the diameter of the pepper fruit is 10 to 30 mm. The highest 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 fruit from the large branches and leaves, the gap length between adjacent first cleaning wheels 512 is equal to or slightly less than the length of the largest pepper fruit of the chili pepper. Specifically, in this embodiment, the first gap 511 is 70 mm.

[0103] Optionally, in order to separate the pepper fruits from the small branches and leaves, the gap length between adjacent second cleaning wheels 532 is equal to or slightly greater than the length of the smallest pepper fruit of the chili pepper, the maximum height of the second protruding tooth 533 is 26 mm, the maximum height of the third protruding tooth 534 is 10 mm, the axial width of the second protruding tooth 533 is 40 mm, and the axial width of the third protruding tooth 534 is 50 mm. Specifically, in this embodiment, the second gap 531 is 46 mm.

[0104] In a preferred embodiment, both the first gap 511 and the second gap 531 are adjustable. For example, the gap can be changed by manually adjusting the assembly method of the corresponding first rotating rod 514 and the fixing bracket of the second rotating rod 535 or adding a reducing gasket, and the gap can be dynamically adjusted by adding a hydraulic system to control the expansion or swing of the fixing bracket of the corresponding first rotating rod 514 and the second rotating rod 535.

[0105] Furthermore, in this embodiment, if Figure 7 As shown, the first side of the receiving plate 710 is mounted on the frame 1 through a first rotating shaft (not numbered in the figure), and the bottom surface of the second side of the receiving plate 710 opposite to the first side abuts against the first cam 720, and the first cam 720 is rotatably mounted on the frame 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, and can be, for example, an elliptical cam, an asymmetric cam, an involute cam, and a cycloidal cam.

[0106] Specifically, the first cam 720 is connected and fixed on the discharge rotating rod 721, and the discharge rotating rod 721 is rotatably set on the frame 1 and is located under the receiving plate 710. The discharge rotating rod 721 is connected to the receiving cam motor 722 through the transmission belt 821 on the synchronous 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, so that the receiving plate 710 moves up and down along the trajectory, thereby better discharging branches.

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

[0108] Specifically, the second cam 521 is fixedly connected to the guiding rotating rod 522. The guiding rotating rod 522 is rotatably arranged on one side of the frame 1 and below the guide plate 520. The guiding rotating rod 522 is connected to the guiding cam motor 523 through the transmission belt 821 on the synchronous pulley 820. The guiding cam motor 523 outputs power to drive the guiding rotating rod 522, and then drives the second cam 521 to rotate, causing the guide plate 520 to periodically move up and down, summarize the pepper mixture processed by the first cleaning layer 510, and enter the second cleaning layer 530 in batches through the vibration of the guide plate 520. At the same time, anti-blocking is achieved through vibration, further improving the cleaning effect and efficiency.

[0109] Among them, referring to Figure 8 , a pair of guiding side plates 526 are also arranged at the middle position of the upper surface of the guide plate 520 to correspond to the position of the first cleaning wheel 512. After the peppers fall between the adjacent first cleaning wheels 512, they are shunted through the cooperation of the guide plate 520 and the guiding side plates 526 and then fall onto the corresponding second cleaning wheels 532. In addition, a front baffle 524 is arranged on the frame 1, and a bottom side plate 525 is arranged on the front baffle 524. Combining Figure 3 and Figure 8 , it can be seen that the front baffle 524 is located at the feeding end of the second cleaning layer 530. The lower end of the front baffle 524 is bent and inclined backward, and a fourth comb tooth is formed at the lower end of the front baffle 524. The fourth comb tooth can be inserted into the corresponding second interval 536 on the frontmost second cleaning wheel 532. When the peppers fall from the guide plate 520, they will be blocked by the front baffle 524 and redirected to fall onto the second cleaning wheel 532. The bottom side plate 525 can be coplanar with the corresponding guiding 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 invention, the picking device 3 further includes a gathering device 4. The gathering device 4 is triangular in structure and has its tip facing forward and is arranged at the front end of the conveyor belt 320 to gather the branches of the peppers to be picked. Through the physical structure design, the pepper branches scattered in the field are gathered towards the central position, enabling the originally widely distributed crops to be more effectively processed in a specific area.

[0111] When the pepper branches are concentrated in 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 the gathering devices 4 can be set according to actual conditions, for example, two, three or more. Specifically, in this embodiment, the number of the gathering devices 4 is two.

[0112] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.
