[0024] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments 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.

[0025] Reference Figure 1 - Figure 4, The utility model provides an embodiment: a buffer crushing device at a transfer point of a belt conveyor, comprising a transfer box 1, a fixed column 2 is fixedly connected to the interior of the transfer box 1, and a screen 3 is rotatably connected to the outer wall of the fixed column 2. The inner wall of the transfer box 1 is fixedly connected to a partition 4, an L-shaped block 5 is fixedly connected to the inner wall of the transfer box 1, and the outer wall of the L-shaped block 5 is fixedly connected to a motor 1 6. The output end of the motor 1 6 is rotatably connected to the interior of the L-shaped block 5 and fixedly connected to a crank 7. The outer wall of the motor 1 6 is fixedly connected to the interior of the transfer box 1, and an impact column 8 is slidably connected to the interior of the L-shaped block 5. The outer wall of the impact column 8 is fixedly connected to a slider 10, and the outer wall of the slider 10 is fixedly connected to a slider 2 11. The outer wall of the L-shaped block 5 is fixedly connected to a rectangular frame 29, and the outer wall of the slider 2 11 is slidably connected to the inner wall of the rectangular frame 29. The outer wall of the impact column 8 is slidably connected to a spring 9. The top of the impact column 8 is in contact with the lower surface of the screen 3, the outer wall of the crank 7 is slidably connected to the outer wall of the slider 10, and a crushing assembly is provided inside the transfer box 1;

[0026] Specifically, the partition 4 divides the transfer box 1 into two parts. The non-crushed part relies on the impact column 8 to intermittently slide inside the L-shaped block 5 and continuously impact the screen 3. The screen 3 will rotate on the outer wall of the fixed column 2 when it is subjected to the impact force. At the same time, when the screen 3 is impacted, it will vibrate to screen out smaller gravel and make it fall into the interior of the transfer box 1. The crushing part crushes the larger gravel that has not been screened out by the screen 3. The spring 9 can reset the impact column 8. When the outer wall of the crank 7 slides over the outer wall of the slider 10, the spring 9 in the contracted state will rebound and push the slider 10 to reset, thereby resetting the impact column 8.

[0027] Reference Figure 1 - Figure 4 The crushing assembly includes a second motor 12, one end of which is fixedly connected to the outer wall of the transfer box 1, and the output end of the second motor 12 is rotatably connected to the inside of the transfer box 1 and fixedly connected to a rotating column 14, the outer wall of the rotating column 14 is fixedly connected to a crushing knife 15, the outer wall of the rotating column 14 is fixedly connected to a gear 16, the outer wall of the gear 16 is meshedly connected to a gear 2 17, the inner wall of the gear 2 17 is fixedly connected to a rotating column 2 18, the outer wall of the rotating column 2 18 is fixedly connected to a crushing knife 2 19, the outer wall of the rotating column 2 18 is rotatably connected to the inside of the transfer box 1, and the outer wall of the rotating column 14 is rotatably connected to the inside of the transfer box 1;

[0028] Specifically, by using the gear 16 and the gear 2 17 , the rotating column 14 and the rotating column 2 18 can rotate in conjunction, and then the crushing knife 1 15 and the crushing knife 2 19 can rotate in conjunction to crush the incoming gravel.

[0029] Reference Figure 1 、 Figure 4 and Figure 5 The outer wall of the transfer box 1 is fixedly connected to a fixed frame 20, and the lower surface of the fixed frame 20 is fixedly connected to a support leg 21; the lower surface of the transfer box 1 is fixedly connected to a fixed cylinder 22, and the inner wall of the fixed cylinder 22 is rotatably connected to a movable cylinder 23; the outer wall of the fixed cylinder 22 is fixedly connected to a motor 3 24, and the output end of the motor 3 24 is fixedly connected to a rotating column 3 25; the outer wall of the rotating column 3 25 is fixedly connected to a gear 3 26, and the outer wall of the gear 3 26 is meshedly connected to the gear ring 13, and the inner wall of the gear ring 13 is fixedly connected to the outer wall of the movable cylinder 23; the outer wall of the movable cylinder 23 is fixedly connected to a limiting ring 28, and a limiting groove 27 is provided on the inner wall of the fixed cylinder 22; the outer wall of the limiting ring 28 is rotatably connected to the inner wall of the limiting groove 27;

[0030] Specifically, the fixed cylinder 22 and the movable cylinder 23 are both used to discharge the crushed and smaller gravel to the rear-end conveying equipment. When the gear ring 13 rotates, it will drive the movable cylinder 23 to rotate on the inner wall of the fixed cylinder 22 and drive the limit ring 28 to rotate on the inner wall of the limit groove 27, thereby realizing the adjustment of the discharge angle.

[0031] When the gear 1 is moved, the impact column 8 is driven by the impactor 2, and the impact column 8 is driven to slide intermittently inside the L-shaped block 5 and continuously impact the screen 3. When the screen 3 is subjected to the impact force, the screen 3 will rotate on the outer wall of the fixed column 2. At the same time, when the screen 3 is impacted, it will vibrate and screen out smaller gravel and make it fall into the interior of the transfer box 1. The remaining larger stones will fall into the side of the partition 4 away from the L-shaped block 5 and be crushed by the crushing knife 1 15 and the crushing knife 2 19. When the motor 2 12 is started during the crushing, the rotating column 14 will drive the crushing knife 15 to rotate and drive the gear 16 to rotate. The rotation of gear 16 will drive gear 2 17 to rotate, thereby causing rotating column 2 18 to rotate on the inner wall of transfer box 1 and driving crushing knife 2 19 to rotate, thereby causing crushing knife 1 15 and crushing knife 2 19 to rotate together to crush larger stones, thereby preventing smaller crushed stones from entering subsequent crushing links and suffering unnecessary secondary crushing, which helps to improve efficiency, reduce energy consumption and equipment wear, and the crushed and screened stones will fall into the fixed cylinder 22 and then be discharged through the movable cylinder 23. When the discharge angle of the movable cylinder 23 needs to be adjusted, it is only necessary to start motor 3 24. When motor 3 24 is started, it will drive rotating column 3 25 to rotate. When rotating column 3 25 rotates, it will drive gear 26 to rotate, thereby causing the gear ring 13 to rotate. When the gear ring 13 rotates, it will drive the movable cylinder 23 to rotate on the inner wall of the fixed cylinder 22, driving the limit ring 28 to rotate on the inner wall of the limit groove 27, thereby realizing the adjustment of the discharge angle, which helps to better connect with the rear-end transportation equipment, ensure smooth transition of materials, and improve the consistency and work efficiency of the entire production line.
