Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a crusher with a noise reduction function. Background Art

[0002] There are many types and applications of crushers. However, when ordinary crushers are used, a large amount of dust will be generated during the production process because the materials are dry, causing serious environmental pollution and threatening the health of operators. Sound insulation panels are installed inside the crusher shell to reduce the noise generated by the collision between the material and the shell during crushing.

[0003] For example, Chinese patent publication number CN213050780U describes a "noise-reducing crusher with dust-proof function, belonging to the technical field of crushers, comprising a housing with a roller track disposed therein. The right side of the housing is fixedly connected to the upper and lower surfaces of a dust collecting device via two fixing brackets. A connecting pipe is fixedly connected to the right side of the housing, a mesh box is threadedly connected to the outer surface of the connecting pipe, and sliding grooves are provided on the front and back of the inner wall of the housing."

[0004] The noise reduction crusher in the above-mentioned comparative document, through the mutual cooperation between the first motor, the fan blades, the connecting pipe, the mesh box, the electric push rod and the slider, enables the device to vacuum the material, thereby ensuring the cleanliness of the environment and protecting the health of the workers. In addition, the device can adjust the distance between the two crushing rollers as needed to adapt the crushing effect to the size of the material, thereby facilitating the use of the workers and improving the practicality of the device.

[0005] However, when the above-mentioned crusher with noise reduction function is in use, the sound insulation board installed on the inner wall of the crushing box of the crusher is easily damaged by the impact of the crushed materials. Therefore, the sound insulation board needs to be replaced regularly. The existing crushing box is closed on all sides, and the sound insulation board on the side wall cannot be disassembled and replaced, resulting in the sound insulation board on the inner wall of the crushing box in the crusher cannot be disassembled and replaced. In addition, the inner wall of the crushing box is closed on all sides, and it is very inconvenient to operate when maintaining and repairing the crushing roller inside the crushing box.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4The utility model provides a technical solution: a crusher with a noise reduction function, comprising a crushing box 1, a sound insulation board 12, a crushing roller 4, and a first synchronization mechanism 5. First side panels 2 are symmetrically installed on both sides of the crushing box 1. A sealing block 22 is integrally formed at the bottom of the first side panel 2. Connecting plates 24 are fixedly installed on the outside of the two sets of first side panels 2. A ball screw 25 is symmetrically and rotatably installed on one side of the crushing box 1 close to the connecting plate 24.

[0024] The other two sides of the crushing box 1 are symmetrically installed with second side plates 3, and the two sides of the bottom of the inner wall of the crushing box 1 are symmetrically fixed with guide plates 33. The two sets of crushing rollers 4 are rotatably installed between the two sets of second side plates 3 through the rotating shaft. A second synchronization mechanism 6 is provided on one side of the top of the crushing box 1. A convex plate 64 is fixedly installed on one side of the top of the crushing box 1. A second synchronous motor 61 is installed on the top of the convex plate 64. The output end of the second synchronous motor 61 and the top of the two sets of ball screws 25 are respectively fixed with a synchronous pulley, and the outer fixed sleeve of the synchronous pulley is provided with a synchronous belt 63. The output end of the second synchronous motor 61 is fixedly connected to the synchronous pulley on the same straight line;

[0025] The synchronous pulleys at the output end of the second synchronous motor 61 and the synchronous belt 63 drive the synchronous pulleys at the ends of the two sets of ball screws 25, so that the two sets of ball screws 25 can drive the connecting plates 24 on the outside of the two sets of first side panels 2, so that the two sets of first side panels 2 can slide upward along the longitudinal slide 21, so that the sound insulation panels 12 on the first side panels 2 can be disassembled and replaced, and the two sets of second side panels 3 and the crushing rollers 4 therebetween can slide out from the inner cavity of the crushing box 1 along the transverse slide 31, so that the sound insulation panels 12 on the upper and lower sides of the two sets of second side panels 3 can be disassembled and assembled, realizing convenient disassembly and assembly of the side panels around the inner wall of the crushing box 1, thereby facilitating the disassembly and replacement of the sound insulation panels 12 on the side panels around the inner wall of the crushing box 1, and at the same time, facilitating the maintenance and inspection of the crushing rollers 4 on the inner wall of the crushing box 1.

[0026] Among them, a hopper 11 is fixedly installed on the top of the crushing box 1, and a sound insulation board 12 is integrally formed on the inner side surfaces of the first side panel 2 and the second side panel 3. An installation groove is opened on the inner wall of the first side panel 2 and the second side panel 3, and the sound insulation board 12 is fixedly installed in the installation groove, and the sound insulation board 12 is flush with the inner wall of the installation groove.

[0027] Among them, longitudinal slide grooves 21 are respectively opened on both sides of the crushing box 1, the first side panel 2 slides in the longitudinal slide groove 21, the connecting plate 24 is a U-shaped structure, and the connecting plate 24 and the two sets of ball screws 25 are connected by threads. The synchronous pulleys at the output end of the second synchronous motor 61 and the synchronous belt 63 drive the synchronous pulleys at the ends of the two sets of ball screws 25, so that the two sets of ball screws 25 can drive the connecting plates 24 outside the two sets of first side panels 2, so that the two sets of first side panels 2 can slide upward along the longitudinal slide groove 21, so that the sound insulation board 12 on the first side panel 2 can be disassembled and replaced.

[0028] Among them, sealing grooves 23 are respectively opened on both sides of the bottom of the crushing box 1, and the bottom sealing blocks 22 of the first side panel 2 are respectively inserted into the corresponding sealing grooves 23. The two groups of first side panels 2 can be inserted into the corresponding sealing grooves 23 through the bottom sealing blocks 22, so that the two sides of the inner cavity of the crushing box 1 can be sealed, and the two groups of second side panels 3 can be sealed with the horizontal slide groove 31 through the sealing strip, so that the crushing box 1 can be sealed around by the side panel. In this way, when the crushing roller 4 crushes the internal material, the material can contact the sound insulation board 12 on the side panel, thereby reducing the noise caused by the collision between the material and the material and the crushing box 1.

[0029] Among them, transverse sliding grooves 31 are respectively opened on both sides of the crushing box 1, and fixing bolts 32 are fixedly installed at the inner corner between the second side plate 3 located on the same side of the first synchronization mechanism 5 and the transverse sliding groove 31. By disassembling the fixing bolts 32 on the side of the second side plate 3 close to the first synchronization mechanism 5, the two groups of second side plates 3 and the crushing rollers 4 between them can slide out of the inner cavity of the crushing box 1 along the transverse sliding grooves 31, so that the sound insulation panels 12 can be disassembled and installed on the upper and lower sides of the two groups of second side plates 3.

[0030] Among them, the first synchronization mechanism 5 includes a first synchronous motor 51, the output end of the first synchronous motor 51 is fixedly connected to the rotating shaft at the end of the crushing roller 4 on the same straight line, and a first connecting frame 52 is fixedly installed between the first synchronous motor 51 and the second side plate 3. The crushing roller 4 is fixedly sleeved on the rotating shaft at the end near the first synchronization mechanism 5, and the two sets of synchronous gears 53 are meshed with each other. The two sets of synchronous gears 53 are meshed and transmitted with each other, so that after the output end of the first synchronous motor 51 drives a set of synchronous gears 53, the two sets of crushing rollers 4 can be driven in the crushing box 1 to extrude and crush the imported materials. The transmission between the two sets of crushing rollers 4 is an existing technical solution and will not be elaborated here.

[0031] Among them, a second connecting frame 62 is fixedly installed between the second synchronous motor 61 and the convex plate 64, and the synchronous pulleys at the ends of the two sets of ball screws 25 are driven by the synchronous pulleys at the output end of the second synchronous motor 61 and the synchronous belt 63, so that the two sets of ball screws 25 can drive the connecting plates 24 outside the two sets of first side panels 2.

[0032] Working principle: When in use, the synchronous pulley at the output end of the second synchronous motor 61 and the synchronous belt 63 drive the synchronous pulleys at the ends of the two sets of ball screws 25, so that the two sets of ball screws 25 can drive the connecting plates 24 on the outside of the two sets of first side panels 2, so that the two sets of first side panels 2 can slide upward along the longitudinal slide groove 21, thereby enabling the sound insulation panels 12 on the first side panels 2 to be disassembled and replaced;

[0033] After replacing the sound insulation panels 12 on the two groups of first side panels 2, the two groups of first side panels 2 can be reset, and then the fixing bolts 32 on the second side panels 3 on the same side close to the first synchronization mechanism 5 can be disassembled, so that the two groups of second side panels 3 and the crushing rollers 4 therebetween can slide out from the inner cavity of the crushing box 1 along the horizontal slide groove 31. In this way, the sound insulation panels 12 can be disassembled and assembled on the upper and lower sides of the two groups of second side panels 3, realizing convenient disassembly and assembly of the side panels around the inner wall of the crushing box 1, thereby facilitating the disassembly and replacement of the sound insulation panels 12 on the side panels around the inner wall of the crushing box 1, and at the same time, facilitating the maintenance and inspection of the crushing rollers 4 on the inner wall of the crushing box 1.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to these embodiments without departing from the principles of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
