[0026] Embodiment 1

[0027] See also Figure 1-6 , a high-efficiency belt cleaner, comprising a first square steel 1, a limit card strip 2, a scraper 3, a gasket 4, a second square steel 5, a sleeve 6, a dial plate 7, a support plate 8, a cover plate 9, a limit plate 10 and a buffer assembly; a limit card strip 2 is fixed to the middle of the upper surface of the first square steel 1 along its length direction, and the limit card strip 2 is in a "T" shape. A card groove 3.1 adapted to the limit card strip 2 is opened at the bottom of the scraper 3 along its length direction. The limit card strip 2 is slidably inserted into the card groove 3.1 at the bottom of the scraper 3. Gaskets 4 are arranged on both sides of the bottom of the scraper 3. The limit card strip 2, the scraper 3 and the two gaskets 4 are fixedly connected by a plurality of bolts; the first square steel 1 is sleeved in the middle of the second square steel 5 and fixedly connected by a plurality of bolts, and sleeves 6 are fixed to the two end portions of the second square steel 5;

[0028] Among them, two shifting plates 7 are symmetrically fixed on the outer surface of each sleeve 6, and the shifting plates 7 are provided with an open groove 7.1 to form a "U" shape; the two ends of the sleeve 6 are divided into a support plate 8 and a cover plate 9, and two connecting blocks 8.1 distributed up and down are fixed on the support plate 8, and two first threaded through holes 8.2 are provided on the connecting block 8.1, and a countersunk hole 9.1 corresponding to the first threaded through holes 8.2 on the two connecting blocks 8.1 is provided on the cover plate 9, and bolts are passed through the countersunk holes 9.1 and the first threaded through holes 8.2 on the connecting blocks 8.1. The support plate 8 and the cover plate 9 are fixedly connected, and a slot 9.2 corresponding to four limit plates 10 is provided on the cover plate 9, and one end of the limit plate 10 is inserted into the slot 9.2. Four limit plates 10 are evenly fixedly provided on the support plate 8 with the sleeve 6 as the center, and a through hole 10.1 is provided on the limit plate 10. The four limit plates 10 correspond to each other in a group, and a buffer component is provided between the two limit plates 10 in each group;

[0029] The buffer assembly includes a guide rod 11, a screw rod 12 and a compression spring 13; the guide rod 11 is inserted into the opening groove 7.1 and two through holes 10.1 located in the vertical direction of the opening groove 7.1, and the middle part of the guide rod 11 is located at the upper and lower sides of the shift plate 7 and is provided with two second threaded through holes 11.1, and the second threaded through holes 11.1 are threadedly connected and penetrated with screw rods 12, and the two screw rods 12 are respectively fitted with the upper and lower surfaces of the shift plate 7, and the two end faces of the screw rods 12 are respectively abutted with the two opposite inner surfaces of the support plate 8 and the cover plate 9; two compression springs 13 distributed up and down are sleeved on the guide rod 11, and the two compression springs 13 are respectively connected between the limit plate 10 and the screw rod 12;

[0030] When the scraper 3 is impacted by the material, the scraper 3 moves and rotates. During the rotation, the scraper 3 also causes the two shift plates 7 on the sleeve 6 to rotate synchronously through the second square steel 5. The shift plates 7 shift the screw 12 to make the guide rod 11 slide up and down in the two through holes 10.1, and as the screw 12 moves up and down, the compression spring 13 is elastically deformed to achieve a certain degree of buffering effect when the scraper 3 is impacted. When disassembling, the cover plate 9 must be removed first, and then the screw 12 on the guide rod 11 is taken out. At this time, the guide rod 11 can be quickly taken out from it, and the compression spring 13 can be replaced.

[0031] The working principle is as follows: after assembly, the two support plates 8 on the sweeper are fixed to the two sides of the bottom of the conveying equipment, so that the blade of the scraper 3 abuts against the lower surface of the belt, so that during the transportation of the material, the material adhering to the surface of the belt is dropped through the scraper 3; the buffer component is used to reduce the impact force of the material on the scraper 3, thereby extending the service life of the equipment.

[0032] Embodiment 2

[0033] See also Figure 4 and Figure 8 Compared with the first embodiment, the second embodiment has substantially the same overall structure and substantially the same working principle. The difference between the two is that the buffer assembly comprises a compression spring 13 and a movable bolt 14; the movable bolt 14 is inserted into the opening slot 7.1 and two through holes 10.1 located in the vertical direction of the opening slot 7.1, and two compression springs 13 distributed up and down are sleeved on the movable bolt 14, and the two compression springs 13 are respectively connected between the limit plate 10 and the dial plate 7;

[0034] When the scraper 3 is impacted by the material, the scraper 3 moves and rotates. During the rotation, the scraper 3 also causes the two dial plates 7 on the sleeve 6 to rotate synchronously through the second square steel 5. The dial plates 7 move up and down, and the hinge bolts 14 do not move. The dial plates 7 cause the compression springs 13 to elastically deform to achieve a certain degree of buffering effect when the scraper 3 is impacted. When disassembling, the compression springs 13 can be replaced by simply pulling out the hinge bolts 14 upwards. Compared with the first embodiment, it is more convenient and quicker.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
