[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] See also Figures 1 to 4 As shown, a bucket elevator cleaning device includes an equipment body 1, a feed port 11, a discharge port 12, a conveying device 2 and a cleaning component 3, wherein the equipment body 1 is a vertically arranged rectangular parallelepiped, and a accommodating space is provided inside the equipment body 1. The feed port 11 is opened on one side of the bottom of the equipment body 1 for receiving materials (grain), and the discharge port 12 is arranged on the other side of the equipment body 1 and is located at the top of the equipment body 1 for discharging materials. The conveying device 2 is rotatably connected in the accommodating space of the equipment body 1 for transferring materials from the feed port 11 to the discharge port 12. The cleaning component 3 is arranged on the conveying device 2 to clean the inner side wall of the equipment body 1 when the conveying device 2 conveys materials.

[0026] It should be noted that the purpose of the bucket elevator is to transport materials to a designated location, and the subsequent process also includes a dust removal process (this process is a prior art and is not within the scope of protection of the present utility model). Therefore, the dust swept out by the cleaning component 3 can be discharged together with the material. The purpose of setting up the cleaning component 3 is to prevent the inner wall of the equipment body 1 from not being cleaned for a long time, causing dust and impurities in the material to adhere to the inner wall of the bucket elevator to form lumps. When the lumps fall into the material, the subsequent dust removal process cannot remove the lumps, thereby affecting the quality of the material.

[0027] In this embodiment, the conveying device 2 includes an active roller 21, a driven roller 22, a belt 23, a bucket 24 and a power unit (not shown in the figure). The active roller 21 is rotatably connected to the upper part of the equipment body 1, and the driven roller 22 is rotatably connected to the lower part of the equipment body 1. The belt 23 is wound around the outside of the active roller 21 and the driven roller 22. The power unit can be a motor in the existing technology, which is used to drive the active roller 21 to rotate, and then drive the belt 23 and the driven roller 22 to rotate together. There are multiple buckets 24, and the multiple buckets 24 are evenly fixed on the outer peripheral surface of the belt 23, and are used to transfer materials from the feed port 11 to the discharge port 12. The cleaning component 3 is arranged on the bucket 24. Preferably, there are multiple cleaning components 3, and the multiple cleaning components 3 are respectively fixed on the multiple buckets 24. It should be noted that the number of cleaning components 3 can be set according to actual needs. For example, in this embodiment, the number of cleaning components 3 is approximately equal to half of the number of buckets 24, and the specific number is not limited.

[0028] In this embodiment, the cleaning assembly 3 includes a convex rod 31, the open end of the convex rod 31 is fixed on the two outer walls adjacent to the bucket 24 and the belt 23, and the other end of the convex rod 31 is fixed with bristles 311, and the free ends of the bristles 311 face the inner wall of the device body 1. Preferably, the bristles 311 are made of nylon, which has strong wear resistance to increase the service life of the cleaning assembly 3. Figure 2 As shown, during implementation, the bucket 24 rotates with the belt 23, thereby driving the U-shaped rod 31 to move. At this time, the bristles 311 fixed at the other end of the U-shaped rod 31 can clean the inner wall of the equipment body 1.

[0029] See also Figure 3 and Figure 4 As shown, preferably, connecting columns 32 are respectively fixed on the two outer side walls of the bucket 24 adjacent to the belt 23, and the open ends of the convex rod 31 are rotatably connected to the two connecting columns 32 respectively. A pull rod 33 is fixed on the side of the open end of the bucket 24 close to the belt 23, and the pull rod 33 is fixedly connected to the convex rod 31 by a tension spring 34. A block 35 for preventing the convex rod 31 from rotating is provided on the side of the open end of the bucket 24 away from the belt 23.

[0030] In this way, when the bevel rod 31 encounters an obstacle (such as material deposited at the bottom of the equipment body 1 or other foreign matter on the side wall of the equipment body 1), the end of the bevel rod 31 close to the bristles 311 can rotate toward the side away from the opening of the bucket 24, that is, the end of the bevel rod 31 close to the bristles 311 can move to the side opposite to the movement direction of the bucket 24 to avoid the bevel rod 31 from rigidly colliding with the material or other foreign matter on the side wall of the equipment body 1, causing damage to the equipment. As the bucket 24 continues to drive the bevel rod 31 to move, the bevel rod 31 will break away from the material and foreign matter interfering with it, and then be reset by the tension spring 34. At this time, the two sides of the bevel rod 31 abut against the block 35, and its bristles 311 continue to clean the inner wall of the equipment body 1.

[0031] Preferably, connecting rods 4 are provided on the two outer side walls of the bucket 24 adjacent to the belt 23. One end of each connecting rod 4 is rotatably connected to a corresponding connecting post 32, and the open end of the convex rod 31 is fixedly connected to each of the two connecting rods 4. The provision of connecting rods 4 facilitates disassembly, repair, or replacement of the cleaning assembly 3. Furthermore, each connecting rod 4 has a slot 41 formed at one end near the convex rod 31. The open end of the convex rod 31 is inserted into the slot 41 of the two connecting rods 4 and fixedly connected by a bolt 5 and a nut 51. This allows for quick connection or disassembly of the convex rod 31 and the connecting rod 4.

[0032] Furthermore, two side walls of the slot 41 are provided with corresponding straight slots 411 extending vertically therethrough. The length direction of the straight slots 411 is parallel to the length direction of the connecting rod 4. A through hole (not shown in the figure) that matches the straight slots 411 is provided on the side wall of the open end of the convex rod 31. The bolt 5 passes through the straight slot 411 on one side of the connecting rod 4, the through hole, and the straight slot 411 on the other side of the connecting rod 4 in sequence and is then screwed into the nut 51. By providing the straight slots 411 and cooperating with the bolt 5 and the nut 51, it is convenient to adjust the depth of the convex rod 31 inserted into the slot 41, thereby adjusting the distance between the bristles 311 and the inner side wall of the device body 1. For example, if the bristles 311 are worn and shortened due to long-term use, the bristles 311 can be made to abut against the inner side wall of the device body 1 by controlling the depth of the convex rod 31 inserted into the slot 41.

[0033] During the specific implementation of the present invention, while the bucket elevator is conveying materials, the bucket 24 of the conveying device 2 drives the cleaning assembly 3 to move. At this time, the bristles 311 of the cleaning assembly 3 clean the inner sidewall of the equipment body 1 to prevent the long-term accumulation of dust and impurities on the inner sidewall of the equipment body 1, which may form lumps and fall off on the inner sidewall of the equipment body 1 and affect the quality of the materials. When the bevel rod 31 encounters an obstacle, the end of the bevel rod 31 closest to the bristles 311 can be rotated toward the side away from the opening of the bucket 24 until the bevel rod 31, which moves with the bucket 24, is free from the interfering materials or foreign objects, thereby preventing the bevel rod 31 from rigidly colliding with the materials or other foreign objects on the sidewall of the equipment body 1 and causing damage to the equipment. By setting the connecting rod 4, the slot 41, the straight slot 411, the through hole, the bolt 5 and the nut 51, the depth of the U-shaped rod 31 inserted into the slot 41 is controlled so that the bristles 311 can abut against the inner wall of the device body 1.

[0034] The above description is only a preferred embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
