[0002] Bucket elevator is a common continuous conveying equipment used for conveying in vertical or near vertical direction. Bucket elevator is suitable for conveying various powdery, granular and small block materials, such as grain, cement, fertilizer, coal, etc., and is widely used in mining, metallurgy, building materials, chemical industry and other industries. It can continuously and efficiently convey in vertical direction, which is suitable for conveying large quantities of materials. Under proper design and use conditions, it has high conveying efficiency and can save energy.

[0003] Bucket elevators are relatively easy to maintain and service due to their relatively simple structure. However, it is also difficult to respond to some problems because of this. If the fluidity of the material itself is poor, such as materials with strong viscosity or materials that are easy to agglomerate, the feed port will be blocked or unable to enter the bucket smoothly. In addition, the height of the feed port device of different specifications of elevators is also different. Therefore, a feeding device for bucket elevators is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a feeding device for a bucket elevator, aiming to improve the problems of feed port blockage due to poor fluidity of materials and different heights of the feed port device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a feeding device for a bucket elevator, comprising a feeding trough, the inner wall of the feeding trough is fixedly connected with a motor trough, the inside of the motor trough is fixedly connected with a first motor, the output end of the first motor is fixedly connected with a disc, the right end of the disc is rotatably connected with a transmission rod, the end of the transmission rod away from the disc is rotatably connected with a force rod, the outside of the force rod is slidably connected with a limit rod, the end of the force rod away from the fixed pin is fixedly connected with a weight block, two top plates are fixedly connected at both sides of the outer wall of the feeding trough, the bottom of the top plate is fixedly connected with a lifting assembly, and the lifting assembly is used to drive the feeding trough to rise and fall;

[0006] As a further description of the above technical solution:

[0007] The lifting assembly includes a telescopic column and a support block, the top of the telescopic column is fixedly connected to the bottom of the top plate, the outside of the telescopic column is slidably connected to a load-bearing column, the bottom of the load-bearing column is fixedly connected to a base, two sliders are slidably connected to the top two sides of the base, the internal threads of the two sliders are connected to a bidirectional threaded rod, the top edge of the base is fixedly connected to a second motor, the output end of the second motor is fixedly connected to the inside of the bidirectional threaded rod, the top of the support block is fixedly connected to the bottom of the top plate, and a support column is arranged between the support block and the slider;

[0021] 1. In the utility model, a motor is provided, and a disc is fixedly connected to the output end of the motor. The disc rotates with the output end of the motor, driving the transmission rod on the motor to make circular motion. At the same time, the transmission rod also drives the force-bearing rod and the weight block to move.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 3The utility model provides an embodiment: a feeding device for a bucket elevator, comprising a feeding trough 1, an inner wall of the feeding trough 1 is fixedly connected with a motor slot 2, a first motor 3 is fixedly connected inside the motor slot 2, a disc 4 is fixedly connected to the output end of the first motor 3, a transmission rod 5 is rotatably connected to the right end of the disc 4, an end of the transmission rod 5 away from the disc 4 is rotatably connected to a force rod 17, an outer sliding connection of the force rod 17 is provided with a limit rod 6, an end of the force rod 17 away from a fixing pin 19 is fixedly connected with a weight block 18, two top plates 7 are fixedly connected to the outer wall of the feeding trough 1 on both sides, a lifting assembly is fixedly connected to the bottom of the top plate 7, the lifting assembly is used to drive the feeding trough 1 to rise and fall, two ends of the limit rod 6 are fixedly connected to the inner wall of the feeding trough 1, the weight block 18 is arranged on the lower side of the inner part of the feeding trough 1, a fixing pin 19 is inserted inside the force rod 17, and the outer wall of the transmission rod 5 is slidably connected to the side of the disc 4 away from the first motor 3.

[0030] Specifically, during use, when the feed trough 1 is blocked due to poor fluidity of the material, the equipment is started, and the output end of the first motor 3 drives the disc 4 to rotate, and the disc 4 drives the transmission rod 5 to rotate around the center of the disc 4. The other end of the transmission rod 5 is connected to the force-bearing rod 17, so the force-bearing rod 17 is also displaced. Because a limiting rod 6 is provided on the outside of the force-bearing rod 17, the force-bearing rod 17 can only move up and down inside the feed trough 1. The force-bearing rod 17 moves up and down with the weight block 18, and the weight block 18 uses its own gravity and the thrust of the force-bearing rod 17 to clear the material blocking the feed trough 1.

[0031] refer to Figure 2-Figure 3 The lifting assembly includes a telescopic column 10 and a support block 8. The top of the telescopic column 10 is fixedly connected to the bottom of the top plate 7. The outside of the telescopic column 10 is slidably connected to the load-bearing column 9. The bottom of the load-bearing column 9 is fixedly connected to a base 14. Two sliders 13 are slidably connected to the top two sides of the base 14. The internal threads of the two sliders 13 are connected with a bidirectional threaded rod 15. The top edge of the base 14 is fixedly connected to a second motor 16. The output end of the second motor 16 is fixedly connected to the inside of the bidirectional threaded rod 15. The top of the support block 8 is fixedly connected to the bottom of the top plate 7. A support column 11 is arranged between the support block 8 and the slider 13. The bottom end of the support column 11 is rotatably connected to the top of the slider 13. The top of the support column 11 is rotatably connected to the bottom of the support block 8. The top of the base 14 is fixedly connected to a fixed block 12. The inside of the fixed block 12 is rotatably connected to the outside of the bidirectional threaded rod 15.

[0032] Specifically, when in use, when the height of the feed trough 1 does not match the feed port, the device is started, the output end of the second motor 16 drives the bidirectional threaded rod 15 to rotate, and the bidirectional threaded rod 15 drives the two sliders 13 to move in opposite directions, and at the same time, the support column 11 and the support block 8 on the top of the slider 13 move with the movement of the slider 13, and the top plate 7 is lifted up or pulled down. The bottom of the top plate 7 is connected to the base 14 through the telescopic column 10 and the load-bearing column 9, so that the feed trough 1 can be moved safely.

[0033] Working principle: When the feed trough 1 is blocked, start the first motor 3, the output end of the first motor 3 drives the disc 4 to rotate, one end of the transmission rod 5 rotates around the center of the disc 4, and at the same time the other end of the transmission rod 5 drives the force rod 17 to move. Because the outer side of the force rod 17 is provided with a limit rod 6, the force rod 17 moves up and down inside the feed trough 1, and because one end of the force rod 17 is connected to the weight block 18, the weight block 18 moves up and down with the force rod 17 to clear the material. When the height of the feed trough 1 does not match the height of the feed port, start the lifting assembly. The output end of the second motor 16 drives the bidirectional threaded rod 15 to rotate, and the two sliders 13 slide toward the opposite or opposite side. When the slider 13 moves, it moves with the support column 11. Because the support column 11 is rotatably connected to the support block 8, the support column 11 moves up and down with the support block 8 to achieve the height adjustment of the feed trough 1.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
