[0032] 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.

[0033] Please see Figures 1 to 5The utility model provides an anti-jamming type pepper and pepper stem separation device, including a bracket 01, a feeding conveyor 02, a pepper stem separator 03, a screening drum 04, a lower conveyor 05, and a pepper stem auxiliary discharge mechanism 06; a walking wheel 11 is arranged at the lower end of the bracket 01; the bracket 01 can be pulled by other equipment such as a tractor to achieve movement. The screening drum 04 is rotatably arranged on the bracket 01, and the inlet end of the screening drum 04 is higher than the outlet end, so that the screening drum 04 is arranged in an inclined manner as a whole; the screening drum 04 only allows peppers and small pepper stems to pass through. Guard plates 08 are arranged on both sides of the lower part of the screening drum 04, and the two guard plates 08 are arranged in a V shape on both sides of the screening drum 04, and the lower end of the guard plate 08 is in contact with the upper end of the lower conveyor 05. The peppers leaking from the screening drum 04 can be gathered to the lower conveyor 05 through the guard plate 08 to facilitate the collection of the peppers. The screening drum 04 is driven by a motor arranged on the bracket 01 to realize the circumferential rotation of the screening drum 04. A chute 07 is arranged below the outlet end of the screening drum 04, and the chute 07 is fixed to the front end of the bracket 01; the chute 07 is arranged obliquely, that is, the inlet end of the chute 07 is higher than its outlet end, and the inlet end of the chute 07 is located directly below the outlet end of the screening drum 04, so as to facilitate the conveyance of the pepper stalks discharged from the screening drum 04. The pepper stalk separator 03 is arranged at the front end of the bracket 01, and the outlet end of the pepper stalk separator 03 is connected to the inlet end of the screening drum 04. The feeding conveyor 02 is arranged at the front end of the bracket 01, and the outlet end of the feeding conveyor 02 is connected to the inlet end of the pepper stalk separator 03, and the inlet end of the feeding conveyor 02 is lower than the outlet end of the feeding conveyor 02, so that the feeding conveyor 02 is arranged obliquely as a whole. The lower conveyor 05 is arranged directly below the screening drum 04 to receive the pepper separated by the screening drum 04. The conveyor belt of the lower conveyor 05 is provided with a scraper mechanism 09, which is evenly distributed along the short side direction of the conveyor belt of the lower conveyor 05. The pepper stem auxiliary discharge mechanism 06 is provided at the outlet end of the screening cylinder 04, and the lowest end of the pepper stem auxiliary discharge mechanism 06 does not contact the inner wall of the screening cylinder 04, and is used to push the pepper stems accumulated at the outlet of the screening cylinder 04 outward for discharge.

[0034] When in use, the peppers stacked in rows are transported to the feeding conveyor 02, and the peppers are transported to the pepper stem separator 03 by the feeding conveyor 02. The pepper stem separator 03 separates the peppers from the pepper stems, and the peppers are separated from the pepper stems by the screening cylinder 04. The separated peppers pass through the screening cylinder 04 and fall into the lower conveyor 05 for transportation. The separated pepper stems are transported to the outlet end of the screening cylinder 04 by their own rotation and the principle of high input and low output. The pepper stems accumulated at the outlet end of the screening cylinder 04 can be discharged through the pepper stem auxiliary discharge mechanism 06 and transported out through the chute 07. In the whole process, the pepper stems will not accumulate at the outlet end of the screening cylinder 04, which can prevent the pepper stems from being blocked, and greatly improve the separation efficiency of peppers and pepper stems.

[0035] In one embodiment, the pepper stem auxiliary discharge mechanism 06 includes a rotating shaft 61 and a material shifting rod 62; the rotating shaft 61 is rotatably disposed at the rear end of the bracket 01 and is located at the outlet end of the screening cylinder 04, the material shifting rod 62 is evenly distributed circumferentially along the radial direction of the rotating shaft 61, and the material shifting rod 62 is evenly distributed along the axial direction of the rotating shaft 61.

[0036] Specifically, the length of the material-moving rod 62 gradually increases from the two ends of the rotating shaft 61 to the middle of the rotating shaft 61, so that the material-moving rod 62 in the same plane is distributed in a semicircular shape along the axial direction of the rotating shaft 61. With such a design, the trajectory formed by the material-moving rod 62 during circumferential rotation can be more compatible with the inner wall of the screening cylinder 04, so as to achieve a larger contact area with the pepper stems, thereby being able to discharge the pepper stems in the screening cylinder 04 to the maximum extent.

[0037] Specifically, leak-proof rods 63 are evenly arranged along the axial direction of the material-moving rod 62. The leak-proof rods 63 on two adjacent material-moving rods 62 are arranged in a staggered manner. The relatively short pepper stalks can be moved to the outside of the screening cylinder 04 by the material-moving rod 62, so that more pepper stalks can be discharged to the maximum extent to prevent the pepper stalks from piling up at the outlet end of the screening cylinder 04.

[0038] In one embodiment, the pepper stem auxiliary discharge mechanism 06 also includes a power unit capable of driving the rotating shaft 61 to rotate.

[0039] Among them, the power unit includes a variable frequency motor and a reducer installed on the bracket 01; the output end of the variable frequency motor will be connected to the reducer, and the output end of the reducer will be connected to the rotating shaft 61, so as to provide power for the entire pepper stem auxiliary discharge mechanism 06 to realize the circumferential rotation of the pepper stem auxiliary discharge mechanism 06.

[0040] In one embodiment, a baffle 71 is provided on one side of the chute 07 away from the screening drum 04. When the material-moving rod 62 moves the pepper stalks to the outside of the screening drum 04, the baffle 71 can block the flying pepper stalks to prevent the pepper stalks from falling on the lower conveyor 05.

[0041] In one embodiment, a cylinder 12 is disposed at the front end of the bracket 01 , and the inclination angle of the feeding conveyor 02 can be controlled by the cylinder 12 .

[0042] Please see Figure 6 , Figure 7In one embodiment, the scraper mechanism 09 includes a base plate 91 and a scraper head 92; the base plate 91 is evenly distributed along the short side direction of the conveyor belt of the lower conveyor 05, and the scraper heads 92 are evenly distributed along the length direction of the base plate 91. When the lower conveyor 05 is operating normally, the scraper mechanism 09 will also rotate synchronously with the lower conveyor 05. At this time, the base plate 91 will scrape the peppers that fall on the lower conveyor 05 outward, and the scraper head 92 will hang the peppers and pepper stems clamped on the screening cylinder 04, thereby preventing them from clogging the leakage holes of the screening cylinder to ensure the efficiency and quality of screening. Among them, the upper end of the scraper head 92 is a spherical structure; it can also prevent the scraper head 92 from scraping the peppers.

[0043] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights 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 covered by the utility model.
