Description

Technical Field

[0001] The utility model relates to the technical field of crushers, and more specifically, to a crusher for preventing material accumulation. Background Art

[0002] A crusher is a mechanical device that breaks large solid materials into smaller particles or powders. It applies a strong mechanical force to the materials through impact, extrusion, grinding, etc. to break them. Crushers are widely used in multiple fields such as mining, chemical industry, pharmaceutical industry, building materials, etc. In the mining industry, it is used to crush ores; in the pharmaceutical industry, it processes medicinal materials into appropriate particle sizes.

[0003] In the existing situation, when the feeding speed or feeding amount of the crusher is too large, it causes materials to accumulate at the feeding port and cannot smoothly enter the crushing chamber. When the feeding speed exceeds the processing capacity of the crushing chamber, the newly entered materials do not have enough time and space to be timely transported into the crushing chamber for processing, thus forming a blockage and accumulation at the feeding port. Due to the material blockage, the crusher will continue to operate under no-load or overloaded conditions, consuming more electrical energy or other energy sources, but unable to effectively complete the crushing work. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a crusher for preventing material accumulation. The technical problem to be solved by the utility model is: the problem that the crusher has material accumulation due to too fast feeding speed, resulting in no-load or overloaded operation of the crusher.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A crusher for preventing material accumulation includes a crushing box. A material control cylinder is fixedly connected and communicated with the top surface of the crushing box. A material distribution shaft is rotatably connected in the material control cylinder. A plurality of material distribution plates are fixedly installed on the outer side of the material distribution shaft, and the end surface of each material distribution plate is in contact with the inner wall of the material control cylinder. A feeding hopper is fixedly connected and communicated with the top of the material control cylinder. An impact box is fixedly installed on the outer side of the material control cylinder. A rotating shaft is rotatably connected in the impact box. The rotating shaft is rotatably connected in the impact box through a torsion spring. The impact box drives the rotating shaft to swing through a driving mechanism. A plurality of pendulums are fixedly installed on the outer side of the rotating shaft. Two crushing rollers are rotatably connected in the crushing box.

[0007] As Figures 1-5 shown, the specific implementation method is: by setting the material distribution shaft and the material distribution plates, the materials fall between the two material distribution plates, and the raw materials fall into the crushing box for crushing by the material distribution plates rotating one week, slowing down the feeding speed. Through the rotating shaft and the torsion spring, after the rotating shaft rotates a certain angle, it can deflect and reset by itself. Through the driving mechanism and the pendulums, the rotating shaft is driven to rotate a certain angle and reset by itself, and the pendulums strike the material control box.

[0008] In a preferred embodiment, the driving mechanism includes a pivot shaft rotatably connected inside the impact box. A plurality of incomplete gears are mounted on the pivot shaft, and a plurality of driven gears are mounted on the rotating shaft. Each incomplete gear meshes with a corresponding driven gear. The pivot shaft is connected to the material distribution shaft through a synchronization mechanism.

[0009] In a preferred embodiment, the synchronization mechanism includes two synchronous pulleys respectively mounted at one ends of the pivot shaft and the material distribution shaft, and a synchronous belt is sleeved on the two synchronous pulleys.

[0010] In a preferred embodiment, a second motor is fixedly installed on the outer side of the material control cylinder, and an output shaft of the second motor penetrates through the material control cylinder and is connected to the material distribution shaft.

[0011] In a preferred embodiment, a protection box is fixedly installed on the outer side of the crushing box, and a first motor is fixedly installed on the outer side of the protection box. An output shaft of the first motor penetrates through the protection box and is connected to one of the crushing rollers. A transmission gear is mounted at one end of each crushing roller, and the two transmission gears mesh with each other.

[0012] In a preferred embodiment, a discharge hopper is fixedly connected to the bottom surface of the crushing box, and two inclined plates are symmetrically installed inside the crushing box.

[0013] In a preferred embodiment, a filter plate is fixedly installed inside the crushing box, and a plurality of vibration motors are symmetrically installed on the top surface of the filter plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By providing devices such as a material distribution shaft and a material distribution plate, the present utility model realizes cutting and storing the continuously falling materials in the material control cylinder through a plurality of material distribution plates. At the same time, as the material distribution plate rotates, the materials are sequentially dropped into the crushing box, thereby avoiding the purpose of material accumulation caused by too fast feeding speed.

[0016] 2. By providing devices such as incomplete gears, a synchronization mechanism, driven gears, pendulums, torsion springs, etc., the present utility model realizes driving rotation through the synchronization mechanism, driving the rotating shaft to rotate half a week through the incomplete gears and the driven gears, and then driving the rotating shaft to reset through the torsion spring, so that the pendulum strikes the material control cylinder, avoiding the adhesion of materials to the inner wall of the material control cylinder, and at the same time ensuring the continuity and stability of feeding.

[0017] In summary, when the utility model is in use, it is simple to operate. By rotating multiple material distribution plates, the feeding speed can be delayed, thus avoiding material accumulation. At the same time, the pendulum swings back and forth to strike the material control cylinder, preventing materials from adhering to the inner wall of the material control cylinder, and ensuring the continuity and stability of feeding.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

A material distribution shaft 15 is rotatably connected inside the material control cylinder 2. A plurality of material distribution plates 16 are fixedly installed on the outer side of the material distribution shaft 15, and the end surface of each material distribution plate 16 is in contact with the inner wall of the material control cylinder 2. A feed hopper 3 is fixedly connected to the top of the material control cylinder 2. An impact box 4 is fixedly installed on the outer side of the material control cylinder 2.

The impact box 4 drives the rotating shaft 21 to swing through a driving mechanism. A plurality of pendulums 5 are fixedly installed on the outer side of the rotating shaft 21. Two crushing rollers 9 are rotatably connected inside the crushing box 1.

[0026] As Figures 1-5 shown, the implementation method is specifically as follows: By setting the material distribution shaft 15 and the material distribution plates 16, the material falls between the two material distribution plates 16. The raw material falls into the crushing box 1 for crushing after the material distribution plate 16 rotates one week, slowing down the feeding speed. Through the rotating shaft 21 and the torsion spring, after the rotating shaft 21 rotates a certain angle, it can deflect and reset itself. Through the driving mechanism and the pendulums 5, the rotating shaft 21 is driven to rotate a certain angle and reset itself, and the pendulums 5 strike the material control cylinder 2.

[0027] The driving mechanism includes a pivot shaft 19, and the pivot shaft 19 is rotatably connected inside the impact box 4. A plurality of incomplete gears 20 are installed on the pivot shaft 19. A plurality of driven gears 22 are installed on the rotating shaft 21, and each incomplete gear 20 is meshed with the corresponding driven gear 22. The pivot shaft 19 is connected to the material distribution shaft 15 through a synchronization mechanism.

[0028] By setting the incomplete gears 20, when the pivot shaft 19 rotates one week, it drives the driven gear 22 to rotate half a week, which is convenient for the rotating shaft 21 to rotate and then reset.

[0029] The synchronization mechanism includes two synchronous pulleys 18, and the two synchronous pulleys 18 are respectively installed at one end of the pivot shaft 19 and the material distribution shaft 15. A synchronous belt 17 is sleeved on the two synchronous pulleys 18 together.

[0030] By setting the synchronous pulleys 18 and the synchronous belt 17, the number of motors used is reduced, thereby reducing the manufacturing cost of the device.

[0031] A second motor 8 is fixedly installed on the outer side of the material control cylinder 2, and the output shaft of the second motor 8 penetrates the material control cylinder 2 and is connected to the material distribution shaft 15.

[0032] A protection box 6 is fixedly installed on the outer side of the crushing box 1. A first motor 7 is fixedly installed on the outer side of the protection box 6, and the output shaft of the first motor 7 penetrates the protection box 6 and is connected to one of the crushing rollers 9.

[0038] When the utility model is used, the material is first put into the feed hopper 3, and then the material falls into the control barrel 2 by gravity, and then the second motor 8 is started to drive the material distribution shaft 15 to rotate, and then the material that continues to fall into the control barrel 2 is cut and stored through multiple material distribution plates 16. At the same time, as the material distribution plates 16 rotate, the material falls into the crushing box 1 in sequence, thereby avoiding excessive feeding speed and material accumulation;

[0039] At the same time, by starting the first motor 7, the two crushing rollers 9 can be driven to rotate in the opposite direction through the two transmission gears 14, thereby crushing the material, and then the filter plate 10 is vibrated by the vibration motor 11, and the crushed material falls on the filter plate 10 and is discharged from the discharge hopper 12 after being filtered;

[0040] At the same time, when the material distribution shaft 15 rotates, the pivot 19 is driven to rotate through the synchronous belt 17 and the synchronous wheel 18, and the cooperation between the incomplete gear 20 and the driven gear 22 drives the rotating shaft 21 to rotate half a circle. At the same time, the rotating shaft 21 is reset through the torsion spring, and drives the pendulum 5 to knock on the control barrel 2 to ensure the continuity and stability of the feeding.
