Description

Technical Field

[0001] This utility model belongs to the technical field of crushing mechanisms, and specifically relates to a hammer crushing mechanism. Background Technology

[0002] A hammer crusher is a mechanical device that uses high-speed rotating hammers to strike and collide with materials to achieve crushing. It is widely used in mining, building materials, chemical, metallurgical and other industries, and is suitable for crushing various medium-hardness and brittle materials, such as limestone, coal gangue and gypsum.

[0003] Existing hammer crushers use a motor to drive a rotor to rotate at high speed. Material enters the machine through the feed inlet and is crushed by the high-speed impact of the hammers. Due to centrifugal force, the material is thrown against the liner on the inner wall of the machine and further crushed by impact, shearing, and friction. After multiple cycles, material meeting the particle size requirements is discharged through the screen, completing the entire crushing process. However, in actual use, because the rotor's position is fixed, some material is broken into small pieces after being crushed by the hammers once. These small pieces may remain between the screen and the hammers, failing to be fully crushed, creating a certain crushing dead zone. This requires personnel to stop the machine and open it to clean the material remaining between the screen and the hammers, which is troublesome, time-consuming, and labor-intensive, placing a certain workload on the processing personnel. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a hammer crushing mechanism that, during the rotation of the rotor, causes the hammers to continuously move closer to and further away from the rotor, enabling the hammers to quickly and thoroughly crush materials, reducing the need for manual intervention and making it easier to use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a hammer crushing mechanism, including a crushing box, a top cover at the top of the crushing box, a liner on the upper inner side of the top cover, multiple crushing teeth on the inner side wall of the liner, an arc-shaped screen plate inside the crushing box, a support rod fixedly installed on one inner wall of the crushing box, a rotor rotatably installed between the support rod and the inner wall of the other side of the crushing box, multiple evenly distributed sliding cylinders on the outer side of the rotor, a sliding frame slidably installed between adjacent sliding cylinders, multiple evenly distributed crushing hammers on the side of the sliding frame away from the rotor, and an adjustment module for controlling the movement of the crushing hammers installed between the rotor and the support rod; a motor installed on the outer side of the crushing box, the output shaft of the motor being fixed to the rotor by a coupling; a bracket installed on the lower side of the crushing box, multiple mounting holes being opened on the lower side of the bracket, and a rubber pad being glued and fixed to the lower surface of the bracket.

[0006] As a further improvement of this utility model, the adjustment module includes drive cylinders evenly arranged on the outside of the rotor. Movable rods are slidably arranged inside the drive cylinders, and the movable rods are respectively connected and fixed to adjacent sliding frames. Reciprocating screws are rotatably arranged inside the drive cylinders, and the reciprocating screws are respectively threaded to adjacent movable rods. Helical gears II are fixedly sleeved on the outer arc surface of the support rod. Helical gears I are fixedly sleeved on the end of the reciprocating screws near the support rod, and helical gears I are meshed with helical gears II.

[0007] As a further improvement of this utility model, a discharge hopper is provided at the lower end of the crushing box, and a feed pipe is provided at the upper end of the top cover.

[0008] As a further improvement of this utility model, a control box is provided on the outside of the crushing box, and the motor is electrically connected to the control box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the motor drives the rotor connected to it to rotate between the support rod and the crushing box, which in turn causes the rotor to drive the crushing hammer to rotate, and the material is crushed by the high-speed impact of the crushing hammer.

[0011] Secondly, the meshing relationship between helical gear two and helical gear one drives the reciprocating screw connected to helical gear one to rotate, thereby causing the moving rod to drive the crusher hammer, which rotates around the transverse center of the rotor, to continuously and steadily approach and move away from the rotor.

[0012] Thirdly, as the rotor rotates, the hammers move closer to and further away from the rotor, allowing the hammers to quickly and thoroughly crush materials, reducing the need for human intervention and making it easier to use.

[0013] Fourth, the bracket can be firmly and stably fixed to the ground by tightening the bolts through the mounting holes with external tools. The rubber pad on the lower surface of the bracket can effectively prevent the bolts from being tightened too much and causing damage to the bracket. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4 As shown, the device includes a crushing box 101, a top cover 102 at the top of the crushing box 101, a liner 107 on the upper side of the inside of the top cover 102, multiple crushing teeth 108 on the inner wall of the liner 107, an arc-shaped screen plate 109 inside the crushing box 101, a support rod 201 fixedly installed on one inner wall of the crushing box 101, a rotor 202 rotatably installed between the support rod 201 and the inner wall of the other inner wall of the crushing box 101, multiple evenly distributed sliding cylinders 203 on the outer side of the rotor 202, a sliding frame 204 slidably installed between the laterally adjacent sliding cylinders 203, multiple evenly distributed crushing hammers 205 on the side of the sliding frame 204 away from the rotor 202, and an adjustment module for controlling the movement of the crushing hammers 205 between the rotor 202 and the support rod 201; a discharge hopper 106 at the lower end of the crushing box 101, and a feed pipe 103 at the upper end of the top cover 102.

[0022] like Figure 2 , 3 As shown, the adjustment module includes drive cylinders 206 evenly arranged on the outside of rotor 202. Movable rods 207 are slidably arranged inside drive cylinders 206. The movable rods 207 are respectively connected and fixed to adjacent sliding frames 204. Reciprocating screws 208 are rotatably arranged inside drive cylinders 206. The reciprocating screws 208 are respectively threaded to adjacent movable rods 207. Helical gears 210 are fixedly sleeved on the outer arc surface of support rod 201. Helical gears 209 are fixedly sleeved on one end of reciprocating screws 208 near support rod 201. Helical gears 209 are meshed with helical gears 210.

[0023] like Figure 1 As shown, a motor 211 is installed on the outside of the crushing box 101, and the output shaft of the motor 211 is fixed to the rotor 202 by a coupling.

[0024] like Figure 2 , 4 As shown, a control box 301 is provided on the outside of the crushing box 101, and the motor 211 is electrically connected to the control box 301.

[0025] During use, the motor 211 is controlled by the control box 301, which drives the rotor 202 connected to it to rotate between the support rod 201 and the crushing box 101. This causes the rotor 202 to drive the crushing hammers 205 installed on the slide 203 to rotate around the transverse center of the rotor 202. The material is crushed by the high-speed impact of the crushing hammers 205. The material is thrown towards the liner 107, and the material is further crushed by the impact, shearing, friction and other forces through the liner 107 and the crushing teeth 108 on the liner 107. After multiple cycles, the material that meets the particle size requirements is discharged through the arc screen plate 109.

[0026] During the rotation of rotor 202, the meshing relationship between helical gear 210 and helical gear 209 drives the reciprocating screw 208 connected to helical gear 209 to rotate. The threaded relationship between reciprocating screw 208 and movable rod 207 drives movable rod 207 to continuously extend and retract from drive cylinder 206. This causes movable rod 207 to drive the crushing hammer 205, which rotates around the transverse center of rotor 202, to continuously approach and move away from rotor 202, so that crushing hammer 205 can quickly and fully crush materials.

[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a bracket 104 is provided on the lower side of the crushing box 101. Multiple mounting holes 105 are provided on the lower side of the bracket 104, and rubber pads are bonded to the lower surface of the bracket 104. Bolts are passed through the mounting holes 105 and tightened using external tools, thus ensuring that the bracket 104 is firmly and stably fixed to the ground. The rubber pads on the lower surface of the bracket 104 effectively prevent excessive tightening of the bolts, which could damage the bracket 104.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
