Abstract

This utility model discloses a material conveying and feeding device for a hoist, including a support frame. A funnel is fixedly connected to the outer surface of the support frame, a filter screen is fixedly connected to the inner wall of the funnel, and a crushing mechanism is fixedly connected to the inner wall of the funnel. Two sliding rods are fixedly connected to the outer surface of the support frame, and sliding cylinders are slidably connected to the outer surfaces of the two sliding rods. A movable shell is fixedly connected to the outer surfaces of the two sliding cylinders, and a threaded cylinder is fixedly connected to the inner wall of the movable shell.

Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a material conveying and feeding device for a hoist. Background Technology

[0002] A hoist is a mechanical device that transports materials by changing their potential energy. The main components of a hoist include an electric motor, rollers / chains, load-bearing devices (such as buckets, feed belts, or cages), and tracks / guide rails.

[0003] Currently, when using elevators to lift powdery or granular materials, the materials are usually placed directly onto the feeding belt. This results in uneven distribution of the materials on the feeding belt, with materials easily accumulating in a certain area of ​​the elevator. This leads to low space utilization, reduced lifting efficiency, and increased wear on mechanical parts, affecting the service life of the equipment. Therefore, we propose a material conveying and feeding device for elevators. Utility Model Content

[0004] The purpose of this utility model is to provide a material conveying and feeding device for a hoist, so as to solve the problems mentioned in the background art.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] A material conveying and feeding device for a hoist includes a support frame. A funnel is fixedly connected to the outer surface of the support frame. A filter screen is fixedly connected to the inner wall of the funnel. A crushing mechanism is fixedly connected to the inner wall of the funnel. Two sliding rods are fixedly connected to the outer surface of the support frame. A sliding cylinder is slidably connected to the outer surface of each of the two sliding rods. A movable shell is fixedly connected to the outer surface of the two sliding cylinders. A threaded cylinder is fixedly connected to the inner wall of the movable shell. Two first bearings are embedded in the outer surface of the support frame. A reciprocating screw is fixedly connected to the inner ring of each of the two first bearings. The outer surface of the reciprocating screw is threadedly connected to the inner surface of the threaded cylinder. A first motor is fixedly connected to the outer surface of the support frame. The output end of the first motor is connected to the outer surface of the reciprocating screw. A flow limiting mechanism is fixedly connected to the bottom surface of the funnel.

[0007] Preferably, the crushing mechanism includes a connecting frame, a second motor is fixedly connected to the upper surface of the connecting frame, and a conical shell is fixedly connected to the upper surface of the connecting frame.

[0008] Preferably, a second bearing is embedded in the bottom surface of the connecting frame, a rotating rod is fixedly connected to the inner ring of the second bearing, and the output end of the second motor is connected to the upper surface of the rotating rod.

[0009] Preferably, a plurality of crushing rods are fixedly connected to the outer surface of the rotating rod, and a brush plate is fixedly connected to the outer surface of each crushing rod.

[0010] Preferably, the flow limiting mechanism includes a connecting slide, and a flow limiting plate is slidably connected inside the connecting slide.

[0011] Preferably, the flow-limiting plate is rotatably connected to a movable rod, and the outer surfaces of the two movable rods are jointly fixedly connected to an elastic element.

[0012] Preferably, two magnetic strips are fixedly connected to the inner sidewall of the connecting slide, and magnetic blocks are fixedly connected to the outer surfaces of the two moving rods.

[0013] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:

[0014] Firstly, the reciprocating screw is driven by the first motor to rotate. With the limiting and supporting effect of the slide bar and slide cylinder, the reciprocating screw drives the moving shell to reciprocate. The material is put into the funnel. Under the action of gravity, the material will fall into the moving shell, thus evenly spreading the material to the carrying device of the elevator, making the material distribution more uniform, thereby improving the utilization space and reducing mechanical wear caused by uneven weight distribution.

[0015] Secondly, the second motor drives the rotating rod and crushing rod to rotate, which can crush lumpy materials that cannot pass through the filter screen, preventing the lumpy materials from getting stuck on the elevator. By moving the flow restrictor, the flow rate of the hopper can be adjusted, so that the material can be evenly fed into the moving shell, reducing the phenomenon of local accumulation and improving the stability of the conveying.

[0025] Please see Figure 1-5 This utility model provides a technical solution for a material conveying and feeding device for an elevator:

[0026] A material conveying and feeding device for a hoist includes a support frame 1. A funnel 2 is fixedly connected to the outer surface of the support frame 1. A filter screen 3 is fixedly connected to the inner wall of the funnel 2. A crushing mechanism 4 is fixedly connected to the inner wall of the funnel 2. Two sliding rods 5 are fixedly connected to the outer surface of the support frame 1. Sliding cylinders 6 are slidably connected to the outer surfaces of the two sliding rods 5. A movable shell 7 is fixedly connected to the outer surfaces of the two sliding cylinders 6. A threaded cylinder 11 is fixedly connected to the inner wall of the movable shell 7. Two first bearings 8 are embedded in the outer surface of the support frame 1. A reciprocating screw 9 is fixedly connected to the inner rings of the two first bearings 8. The outer surface of the reciprocating screw 9 is connected to the internal thread of the threaded cylinder 11. The outer surface of the support frame 1 is fixedly connected to the first motor 10. The output end of the first motor 10 is connected to the outer surface of the reciprocating screw 9. The bottom surface of the funnel 2 is fixedly connected to the flow limiting mechanism 12. Specifically, the first motor 10 drives the reciprocating screw 9 to rotate. With the support and limiting effect of the slide cylinder 6 and the slide rod 5, the reciprocating screw 9 drives the moving shell 7 to move in a cycle. The material falls into the moving shell 7 through the funnel 2. With the help of the flow limiting mechanism 12, the flow rate of the material is adjusted so that the material can be evenly distributed on the carrying device of the elevator.

[0027] In this embodiment, the crushing mechanism 4 includes a connecting frame 401, a second motor 405 fixedly connected to the upper surface of the connecting frame 401, and a conical shell 406 fixedly connected to the upper surface of the connecting frame 401; a second bearing 402 is embedded in the bottom surface of the connecting frame 401, a rotating rod 403 is fixedly connected to the inner ring of the second bearing 402, and the output end of the second motor 405 is connected to the upper surface of the rotating rod 403; a plurality of crushing rods 404 are fixedly connected to the outer surface of the rotating rod 403, and a brush plate 40 is fixedly connected to the outer surface of each crushing rod 404. 7; Specifically, the second motor 405 drives the rotating rod 403 and the crushing rod 404 to rotate. The crushing rod 404 can crush the agglomerated material blocked by the filter screen 3 to prevent the agglomerated material from affecting the normal feeding. The crushing rod 404 drives the brush plate 407 to rotate, so that the bristles on the brush plate 407 clean the filter screen and prevent the material from clogging the screen 3. The conical shell 406 can isolate the material from the second motor 405. The upper part of the connecting frame 401 is triangular, which can prevent the material from accumulating on the connecting frame 401.

[0028] In this embodiment, the flow limiting mechanism 12 includes a connecting sliding shell 1201, with a flow limiting plate 1202 slidably connected inside the connecting sliding shell 1201; a moving rod 1203 is rotatably connected inside the flow limiting plate 1202, and an elastic element 1204 is fixedly connected to the outer surfaces of the two moving rods 1203; two magnetic strips 1205 are fixedly connected to the inner sidewall of the connecting sliding shell 1201, and magnetic blocks 1206 are fixedly connected to the outer surfaces of the two moving rods 1203; specifically, by moving the flow limiting plate 1202, the flow rate of the funnel 2 can be adjusted so that the material falls evenly into the moving shell 7; the flow limiting plate 1202 can be fixed by the mutual attraction between the magnetic blocks 1206 and the magnetic strips 1205; and the magnetic blocks 1206 and the magnetic strips 1205 can be separated by bringing the moving rods 1203 closer together.

[0029] Working principle: When the elevator is used as a material conveying and feeding device, the user first puts the material into the funnel 2. The lumpy material will be blocked by the filter screen 3, and the remaining material will fall into the elevator through the funnel 2 and the moving shell 7. The second motor 405 is turned on to rotate the rotating rod 403 and the crushing rod 404, so that the crushing rod 404 hits the lumpy material and crushes it, so that it can pass through the filter screen 3. The two moving rods 1203 are brought closer to each other, so that the magnetic block 1206 is separated from the magnetic strip 1205. The moving flow limiting plate 1202 can adjust the flow rate of the material discharged from the funnel 2. When the moving rods 1203 are released, the elastic element 1204 will separate the two moving rods 1203, and the magnetic block 1206 will be attracted to the magnetic strip 1205. The first motor 10 is turned on to drive the reciprocating screw 9 to rotate, so that the moving shell 7 moves in a cycle and evenly sprinkles the material onto the elevator.
