Description

Technical Field

[0001] The utility model relates to the technical field of pepper screening and separation equipment, in particular to a multi-layer sorting dry pepper cleaning device. Background Art

[0002] Chili peppers are rich in nutrients and beneficial to human health, and are favored by the general public. With the improvement of the technology of extracting capsanthin from chili peppers, the planting area of ​​chili peppers has been expanding. The traditional method of harvesting chili peppers is mainly manual. After harvesting, the chili products need to be separated from the branches and stems manually. The harvesting efficiency is low and the labor intensity is high. There is an urgent need to realize mechanized operation.

[0003] In view of the above-mentioned problems, a utility model patent with announcement number CN211463918U discloses a pepper sorting and separation device, which puts peppers and mixed branches and debris into a feed hopper, and the flattening plate of the flattening part rotates continuously to flatten the materials, and smaller branches and peppers fall through the comb teeth of the upper separation rack, and larger branches and peppers that have not fallen off pass through the first processing box and are separated by the separation rod, which is conducive to the separation and falling of the peppers. Finally, the larger branches enter the second processing box and are crushed by the crushing teeth and then fall off. The dense teeth on the lower separation rack do not allow the peppers to pass through, and the peppers are carried forward to the first-level lifting and air separation part and the second-level lifting and air separation part, and are transported to the air selection device by the lifting conveyor belt device to take out most of the branches. Finally, the separated peppers are transported to the collection device by the transportation part for later processing.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations on the present invention.

[0034] Please see Figures 1 to 8The utility model provides a multi-layer sorting dry chili cleaning device, comprising an upper separation screen 01, a middle vibrating screen 06, a lower separation screen 02, a pressing and cutting mechanism 03, and an impurity cleaning component 04; the upper separation screen 01 is arranged directly above the lower separation screen 02, and the inlet end of the upper separation screen 01 is lower than the outlet end, so that the upper separation screen 01 is arranged obliquely. The upper separation screen 01 allows chili and small pieces of debris to pass through; the lower separation screen 02 does not allow chili to pass through, and only allows tiny impurities to pass through.

[0035] The middle vibrating screen 06 is tilted between the upper separation screen 01 and the lower separation screen 02. The tilting direction of the middle vibrating screen 06 is the same as that of the upper separation screen 01. The outlet end of the middle vibrating screen 06 is located directly above the lower separation screen 02. The upper separation screen 01, the middle vibrating screen 06, and the lower separation screen 02 can form a top-down separation screening, thereby separating impurities mixed in the pepper.

[0036] The pressing and cutting mechanism 03 is arranged near the inlet end of the upper separation screen 01; the pressing and cutting mechanism 03 is used to press and cut the peppers and the mixed branches and debris on the upper separation screen 01, which can not only flatten the peppers, but also cut the large pepper stalks and plastic films into small pieces. The impurity cleaning component 04 includes a shell 41, a first turning part 42, a second turning part 43, and a cleaning part 44; the shell 41 is arranged on the upper separation screen 01 and is located behind the pressing and cutting mechanism 03, the first turning part 42, the second turning part 43, and the cleaning part 44 are rotatably arranged in the shell 41, the first turning part 42 and the second turning part 43 do not contact the surface of the upper separation screen 01, the cleaning part 44 is arranged above the first turning part 42 and the second turning part 43, and the cleaning part 44, the first turning part 42, and the second turning part 43 are arranged in a herringbone shape. When the cleaning part 44 rotates circumferentially, it can shear and grind impurities attached to the first turning part 42 and the second turning part 43.

[0037] The inlet end of the dust suction mechanism 07 is connected to the housing 41 and the outlet end facing the middle vibrating screen 06. During the sorting process, the dust suction mechanism 07 can suck away the generated dust and plastic film to achieve the purpose of removing impurities and reducing dust.

[0038] When in use, the pressing and cutting mechanism 03 first presses and cuts the peppers and the mixed branches and debris on the upper separation screen 01, which can not only flatten the peppers but also cut the large pepper stems and plastic films into small pieces; then, the cleaning part 44, the first turning part 42, and the second turning part 43 rotate in the circumferential direction, and the first turning part 42 and the second turning part 43 are used to stir the materials, which can not only turn the materials but also stir the mixed peppers into small pieces. The long pepper stems and plastic film are captured, and then the impurities attached to the first turning part 42 and the second turning part 43 can be sheared and ground by the relative rotation of the cleaning part 44 and the first turning part 42 and the second turning part 43, and then the peppers can be sorted by the screening and separation effect of the upper separation screen 01, the middle vibrating screen 06 and the lower separation screen 02; and during the sorting process, the dust and plastic film generated can be sucked away by the dust suction mechanism 07 to achieve the purpose of removing impurities and reducing dust. In use, not only can the plastic film be sorted out from the peppers, but also jamming can be prevented, which effectively ensures the normal operation of the sorting and improves the sorting efficiency.

[0039] In one embodiment, the first turning part 42 and the second turning part 43 have the same structure, and the first turning part 42 includes a turning shaft 421 and a turning rod 422; the turning shaft 421 is rotatably arranged on the housing 41 along the short side direction of the upper separation screen 01, and the turning rods 422 are evenly distributed along the axis direction of the turning shaft 421 at equal intervals, and the turning rods 422 are evenly distributed along the circumferential direction of the turning shaft 421. The first turning part 42 and the second turning part 43 have the same rotation direction.

[0040] Specifically, one end of the turning rod 422 away from the turning shaft 421 is bent, so that the turning rod 422 has an "L" shape as a whole; so that the turning rod 422 can not only stir the material so that the lower layer of material can be turned upward, but also can be used to capture the long pepper stalks and the plastic film mixed in the pepper.

[0041] In one embodiment, the cleaning part 44 includes a cleaning shaft 441 and a cleaning sheet 442; the cleaning shaft 441 is rotatably arranged on the shell 41 along the short side direction of the upper separation screen 01, and the cleaning sheets 442 are evenly distributed along the axial direction of the cleaning shaft 441 at equal intervals, and the cleaning sheets 442 are evenly distributed along the circumferential direction of the cleaning shaft 441, and the cleaning sheets 442 and the turning rod 422 are staggered. When the cleaning part 44 rotates circumferentially, the first turning part 42 and the second turning part 43 also rotate circumferentially, but the rotation direction of the cleaning part 44 is opposite to the rotation direction of the first turning part 42 and the second turning part 43, so that the cleaning part 44 and the first turning part 42 and the second turning part 43 form a counter-cross rotation. When a plastic film is wrapped around the turning rod 422, or a chili stalk is stuck, the plastic film or the chili stalk can be sheared and ground by the counter-cross rotation formed by the cleaning sheet 442 and the turning rod 422, which can not only play the role of cleaning the turning rod 422, but also capture and cut large impurities, so as to facilitate the screening and separation of the impurities.

[0042] Specifically, the end of the cleaning sheet 442 away from the cleaning shaft 441 is bent in an arc shape, and the bending direction of the end of the cleaning sheet 442 is opposite to the bending direction of the turning rod 422. Therefore, during the circumferential rotation of the cleaning sheet 442, a large circumferential rotation force can be formed at the end of the cleaning sheet 442. When the end of the cleaning sheet 442 contacts the plastic film wrapped around the turning rod 422 or the stuck pepper stem, it can have a large impact force, thereby forming a large shear force between the turning rod 422 and the cleaning sheet 442, so as to chop the plastic film or the pepper stem to the maximum extent.

[0043] Specifically, a plurality of convex strips 443 are provided at equal intervals on both sides of the bent portion of the cleaning sheet 442. When the plastic film is wound around the turning rod 422, the rotational force generated by the circumferential rotation of the cleaning sheet 442 will cause the convex strips 443 to have a large tangential force. When the convex strips 443 come into contact with the plastic film, the convex strips 443 and the plastic film on the turning rod 422 will have a large friction force, thereby grinding the plastic film; that is, when the cleaning sheet 442 rotates, it can form a shear force on the plastic film and can use the convex strips 443 to form tangential friction, which can greatly improve the crushing and cleaning effect of the plastic film.

[0044] In one embodiment, the pressing and cutting mechanism 03 includes a flattening shaft 31 and a flattening and crushing plate 32; the flattening shaft 31 is rotatably arranged along the short side direction of the upper separation screen 01, and the flattening and crushing plate 32 is an equilateral triangle structure. The flattening and crushing plates 32 are arranged at equal intervals along the axial direction of the flattening shaft 31, and the flattening and crushing plates 32 are evenly distributed along the circumferential direction of the flattening shaft 31.

[0045] In one embodiment, in order to facilitate the transportation of materials to the upper separation screen 01, a feeding conveyor 05 is also provided. The inlet end of the feeding conveyor 05 is lower than the outlet end of the feeding conveyor 05, and the outlet end of the feeding conveyor 05 is located directly above the inlet end of the upper separation screen 01.

[0046] Specifically, a pressure roller 51 is rotatably provided on the feeding conveyor 05 .

[0047] In one embodiment, the middle vibrating screen 06 includes a screen body 61 and a power unit 62; the screen body 61 is disposed between the upper separation screen 01 and the lower separation screen 02, and a first screen plate 63 and a second screen plate 64 are sequentially disposed from top to bottom in the screen body 61; the inclination direction of the first screen plate 63 and the second screen plate 64 is consistent with the inclination direction of the upper separation screen 01, and the outlet ends of the first screen plate 63 and the second screen plate 64 are located directly above the lower separation screen 02, and the power unit 62 is disposed on the screen body 61 to drive the screen body 61 to vibrate. Among them, the first screen plate 63 and the second screen plate 64 only allow peppers and small particles of impurities to pass through.

[0048] Specifically, the dust suction mechanism 07 includes an exhaust fan 71, and a first pipe 72 and a second pipe 73 are provided at the inlet end of the exhaust fan 71. The first pipe 72 is connected to the top of the housing 41, and the inlet end of the second pipe 73 is directly opposite to the outlet ends of the first sieve plate 63 and the second sieve plate 64. The exhaust fan 71 will suck away the dust generated by the first sieve plate 63 and the second sieve plate 64, as well as the screened plastic film and some impurities of pepper stems and pepper leaves through suction to reduce the dust around the entire device.

[0049] Specifically, a trumpet-shaped air inlet 74 is provided at the inlet end of the second pipe 73. A partition net is provided at the air inlet 74 to prevent the pepper from being sucked in.

[0050] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
