Description

Technical Field

[0001] This utility model belongs to the field of crusher technology, and specifically relates to a toothed roller crusher. Background Technology

[0002] Toothed roll crushers are a type of crushing equipment widely used in industries such as mining, building materials, and chemicals. They are particularly suitable for coarse and medium crushing of brittle materials with medium hardness or less. They achieve material crushing by shearing, squeezing, and splitting the material through two relatively rotating toothed rolls.

[0003] Existing toothed roll crushers use a drive module to rotate two toothed rollers. Material is then poured into a feed hopper located on the upper side. The material enters from above between the two rollers and is crushed by the squeezing of the rotating rollers and the shearing action of the toothed rollers. Qualified particles are discharged from the roller gap, while oversized materials continue to be crushed until they meet the standard. In actual use, since the materials that toothed roll crushers need to process are usually coal, limestone, coke, etc., these materials are large and brittle. After being poured into the feed hopper, they may get stuck together and block the inside of the feed hopper, affecting the crushing efficiency. At this time, personnel need to use hand tools to assist in feeding the material, which is troublesome, time-consuming and labor-intensive. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a toothed roller crusher, which can assist the smooth feeding of materials by driving the feed hopper in the feed hopper to reciprocate and vibrate, so that the materials can be quickly crushed by the toothed roller in the first time. It is easy to operate and convenient for personnel to use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a toothed roller crusher, including a crushing box, a feeding box on the upper side of the crushing box, a feeding hopper on the upper surface of the feeding box, a discharge hopper on the lower side of the crushing box, symmetrically distributed guide rails inside the feeding box, a movable seat slidably arranged between the guide rails, symmetrically distributed guide grooves on the movable seat, a shaking hopper slidably arranged between the guide grooves, and a control module for driving the shaking hopper to shake on the feeding box; a support is provided on the lower side of the crushing box, and a buffer rubber pad is glued and fixed to the lower surface of the support.

[0006] As a further improvement of this utility model, the control module includes multiple top support rods rotatably mounted on the inner wall of the feed box. The end of each top support rod away from the inner wall of the feed box is rotatably connected to the shaking hopper. A sliding column is provided on the side of the shaking hopper away from the top support rod. The sliding column is slidably connected to the movable seat. A return spring is provided between the movable seat and the shaking hopper. The return spring is sleeved on the outside of the sliding column. The feed box is also provided with symmetrically distributed electric push rods. A U-shaped seat is provided on the side of the movable seat near the electric push rod. The telescopic end of the electric push rod is connected and fixed to the U-shaped seat.

[0007] As a further improvement of this utility model, the crushing box is equipped with symmetrically distributed toothed rollers for rotation, and a mounting box is provided on the outside of the crushing box. The ends of the toothed rollers near the mounting box all extend into the interior of the mounting box, and gears are fixedly sleeved on the ends of the toothed rollers near the mounting box. The gears are meshed and connected. A motor is provided on the mounting box, and the output shaft of the motor is fixed to the adjacent toothed rollers by a coupling.

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

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

[0010] Firstly, the output shaft of the motor drives the toothed roller connected to it to rotate. Through the meshing relationship between the gears, the two toothed rollers rotate synchronously in opposite directions, thus stably crushing the material.

[0011] Secondly, the telescopic end of the electric push rod extends and retracts synchronously in a cyclical manner, thereby driving the shaking hopper to continuously sway back and forth through the movable seat.

[0012] Third, during the reciprocating motion of the hopper, the return force of the reset spring pushes the hopper backward. Since the top support rod is of fixed length, it can drive the hopper to move back and forth during the reciprocating motion.

[0013] Fourth, when crushing materials, the toothed roller can drive the feed hopper in the feed hopper to reciprocate in the front-back and left-right directions to assist the smooth feeding of materials, so that the materials can be quickly crushed by the toothed roller in the first time. It is easy to operate and convenient for personnel to use. 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 , 3 As shown, the device includes a crushing box 102, a feeding box 103 on the upper side of the crushing box 102, a feeding hopper 104 on the upper surface of the feeding box 103, and a discharge hopper 105 on the lower side of the crushing box 102. Symmetrically distributed guide rails 201 are arranged inside the feeding box 103, and movable seats 202 are slidably arranged between the guide rails 201. Symmetrically distributed guide grooves 203 are formed on the movable seats 202, and a shaking hopper 204 is slidably arranged between the guide grooves 203. A control module for driving the shaking hopper 204 to shake is also provided on the feeding box 103. The control module includes multiple [unclear - possibly a component or component] rotatably disposed on the inner wall of the feeding box 103. The top support rod 209 has one end away from the inner wall of the feed box 103 that is rotatably connected to the shaking hopper 204. The side of the shaking hopper 204 away from the top support rod 209 is provided with a sliding column 207, which is slidably connected to the movable seat 202. A return spring 208 is provided between the movable seat 202 and the shaking hopper 204, and the return spring 208 is sleeved on the outside of the sliding column 207. The feed box 103 is also provided with symmetrically distributed electric push rods 206. The side of the movable seat 202 near the electric push rod 206 is provided with a U-shaped seat 205, and the telescopic ends of the electric push rods 206 are connected and fixed to the U-shaped seat 205.

[0022] like Figure 2 , 4As shown, symmetrically distributed toothed rollers 106 are rotatably arranged inside the crushing box 102. A mounting box 108 is provided on the outside of the crushing box 102. The ends of the toothed rollers 106 near the mounting box 108 all extend into the interior of the mounting box 108. Gears 107 are fixedly sleeved on the ends of the toothed rollers 106 near the mounting box 108, and the gears 107 are meshed with each other. A motor 109 is provided on the mounting box 108. The output shaft of the motor 109 is fixed to the adjacent toothed rollers 106 by a coupling.

[0023] like Figure 1 , 2 As shown, a control board 301 is provided on the outside of the crushing box 102, and the electric push rod 206 and the motor 109 are both electrically connected to the control board 301.

[0024] In use, the control board 301 regulates the operation of the electric push rod 206 and the motor 109, so that the output shaft of the motor 109 drives the toothed roller 106 connected to it to rotate, and the two toothed rollers 106 rotate synchronously in opposite directions through the meshing relationship between the gears 107.

[0025] The telescopic end of the electric push rod 206 extends and retracts synchronously in a cyclical manner, thereby driving the movable seat 202 to slide back and forth between the guide rails 201. The movable seat 202 then drives the shaking hopper 204 to continuously sway left and right. During the left and right reciprocating motion of the shaking hopper 204, the return force of the return spring 208 pushes the shaking hopper 204 backward. Since the top support rod 209 is of fixed length, when the movable seat 202 drives the shaking hopper 204 to move to the leftmost or rightmost position, the return force of the return spring 208 drives the shaking hopper 204 to move backward. When the movable seat 202 drives the shaking hopper 204 to move to the middle position, the top support rod 209 drives the shaking hopper 204 to move forward. Thus, through the cooperation of the return spring 208 and the top support rod 209, the shaking hopper 204 can move back and forth during its left and right reciprocating motion, which can drive the reciprocating vibration of the shaking hopper 204 to assist in the smooth feeding of materials.

[0026] The material to be fed is poured into the feed hopper 104, and then the material enters the inside of the shaking hopper 204 through the feed hopper 104. The vibration of the shaking hopper 204 causes the material to fall between the toothed rollers 106, and the toothed rollers 106 rotate synchronously in opposite directions to crush it.

[0027] According to another embodiment of the present invention, such as Figure 1 , 4As shown, a support 101 is provided on the lower side of the crushing box 102, and a buffer rubber pad is bonded and fixed to the lower surface of the support 101. During use, the buffer rubber pad bonded and fixed to the lower surface of the support 101 allows for flexible contact between the support 101 and the ground, thereby effectively preventing damage caused by the support 101 scraping against the ground during use.

[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.
