[0028] The following will, with reference to the drawings, elaborate on some embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0029] Please refer to Figures 1 to 6The embodiment of the utility model provides a bucket elevator and a shot blasting device, including a shell 1, a feed port 2 is opened on the lower side of the shell 1, a feeding mechanism is installed inside the shell 1, a feed port 2 is opened on the lower side of the shell 1, the feeding mechanism includes a rotating shaft 1 6 and a rotating shaft 2 9 rotatably arranged at the upper and lower ends of the shell 1, a symmetrical sprocket 1 7 is connected to the rotating shaft 1 6, a symmetrical sprocket 2 10 is connected to the rotating shaft 2 9, a chain 8 is meshed on the sprocket 1 7 and the sprocket 2 10, a plurality of hoppers 11 are installed on the chain 8, the rotating shaft 1 6 is driven by a motor, and the material is transported to the feed port 2 through a screw conveyor or other feeding mechanism, and the material falls into the circulating hopper 11 one by one, and the material is fed by the rotation of the chain 8, and the material can be discharged through the discharge port opened on the upper side of the shell 1.

[0030] A rotating shaft 3 12 is rotatably provided in the middle position of the outer shell 1, and a tensioning wheel 13 is connected to the rotating shaft 3 12. The tensioning wheel 13 is engaged with the chain 8. The chain 8 is tightened by the tensioning wheel 13, so that the chain 8 and the hopper 11 are concave inward, which not only improves the stability of the chain 8 and the hopper 11 moving, but also makes the unemptied materials in the hopper 11 fall to the bottom of the outer shell 1 and wait for recovery.

[0031] In order to recycle the material at the bottom of the shell 1, a receiving plate 14 is provided at the bottom of the shell 1. The interior of the receiving plate 14 is an inwardly concave arc. The receiving plate 14 is used to receive the material dropped during feeding and discharging. The concave structure is beneficial to prevent the material from overflowing. Tonghua City hinges one side of the receiving plate 14 with the wall of the discharge port opened in the shell 1, and the other end of the receiving plate 14 is hinged to the piston end of the cylinder 20. The cylinder 20 is movably installed at the bottom of the shell 1. Through the pushing of the cylinder 20, one end of the receiving plate 14 can be moved upward, so that the receiving plate 14 is in an inclined state, which is convenient for recycling materials.

[0032] Furthermore, slide grooves 15 are provided on both sides of the material receiving plate 14, and push plates 17 are slidably connected in the slide grooves 15. The bottom of the push plate 17 fits with the inside of the material receiving plate 14. A screw rod 16 is rotatably provided in one of the slide grooves 15. The screw rod 16 is threadedly connected to one side of the push plate 17. The screw rod 16 is driven by a motor, and the motor is embedded in the inner wall of the slide groove 15. When the screw rod 16 rotates, the push plate 17 pushes the material in the material receiving plate 14 downward, thereby promoting material recovery and reducing material waste.

[0033] In addition, a material guide plate 18 is symmetrically arranged at the lower end of the housing 1 . The material guide plate 18 is in an inclined structure, so that all materials dropped from above are urged to enter the receiving plate 14 .

[0034] Since a receiving plate 4 is provided on one side of the discharge port opened at the lower side of the shell 1, the receiving plate 4 guides the discharged material so that the material enters other conveying mechanisms or containers.

[0035] In order to seal the discharge port, a first cylinder 19 is installed on the side wall of the outer shell 1. The piston end of the first cylinder 19 is connected to the upper side of the sealing plate 3. The sealing plate 3 seals the discharge port. When recycling materials, the first cylinder 19 drives the sealing plate 3 to move upward to expose the discharge port. Since clamping grooves 5 are formed on both sides of the receiving plate 4, both sides of the sealing plate 3 are clamped and matched with the two clamping grooves 5 respectively. When the sealing plate 3 moves upward, it needs to be separated from the clamping grooves 5.

[0036] On the other hand, the present application also provides a shot blasting device for a bucket elevator, including: a shot blasting machine 22. A shot and sand separator 23 is installed at the upper end of the shot blasting machine 22. The feeding end of the shot and sand separator 23 is connected to the discharging end of the outer shell 1 through a conveying pipeline 21. The feeding mechanism conveys materials into the shot blasting machine 22 through the conveying pipeline 21 for shot blasting treatment.

[0037] In summary, the working principle of a bucket elevator and a shot blasting device according to an embodiment of the present utility model is as follows: when the first rotating shaft 6 and the first sprocket 7 rotate, the second rotating shaft 9, the second sprocket 10 and the chain 8 are driven to operate, and the chain 8 drives the hopper 11 to move up and down in a cycle to realize the conveying of materials. When the materials are being conveyed, the dropped materials are received by the receiving plate 14. When recycling, the second cylinder 20 drives one end of the receiving plate 14 to move upward, causing the receiving plate 14 to tilt. Combining with the sliding of the pushing plate 17 in the receiving plate 14, the materials are recycled uniformly.

[0038] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes.
