Description

An impact roller crusher Technical Field

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

[0002] The impact roller crusher is a composite crushing equipment that combines the principles of impact crushing and rolling crushing. It is mainly used for medium and fine crushing of medium-hard or brittle materials (such as limestone, sandstone, coal gangue, etc.). Through the synergistic effect of high-speed rotating impact components and relatively rolling rollers, it achieves multi-stage crushing of materials, and has both high crushing efficiency and controllable output particle size.

[0003] In existing impact roller crushers, after material enters the crushing chamber, it is struck by high-speed rotating hammers and thrown onto the impact plate, achieving primary crushing through impact force (for large pieces of material). The crushed material falls into the roller area, where secondary crushing (refining particle size and reducing needle-like and flaky particles) is completed through the squeezing and shearing forces between the rollers. However, in actual use, after the crushed material falls into the roller area, it is evenly dispersed on the filter screen. Since the position of the rollers is fixed, some material is difficult to be crushed by the rollers when they rotate. Personnel need to stop the machine and use hand tools to shovel the material to a position where the rollers can crush it, and then restart the machine to continue crushing. This process is cumbersome, time-consuming, and labor-intensive, affecting the efficiency of crushing. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing an impact roller crusher that can be adjusted and moved during the crushing process, thereby quickly and uniformly crushing the materials to be crushed, ensuring the crushing effect and improving the crushing efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an impact roller crusher, including a roller box, an impact box is provided on the upper side of the roller box, a feed hopper is provided at the upper end of the impact box, symmetrically distributed rotating seats are rotatably arranged inside the roller box, symmetrically distributed sliding cylinders are slidably arranged on the lower side of the rotating seats, and sliding rods are slidably arranged inside the sliding cylinders, an L-shaped seat is provided at the bottom end of the sliding rod on one side, a motor seat is provided at the bottom end of the sliding rod on the other side, and a roller shaft is rotatably arranged between the motor seat and the adjacent L-shaped seat. An adjustment module is also provided on the rotating seat, which is used to adjust the extension length of the sliding rod; a first screen is provided at the bottom inside the impact box, and a second screen is provided at the bottom inside the roller box; both the first screen and the second screen are made of composite ceramic material.

[0006] As a further improvement of this utility model, the adjustment module includes a connecting box symmetrically arranged on the lower side of the rotating seat. The rotating seat has symmetrically distributed sliders that are slidably arranged inside. The lower side of each slider is rotatably arranged with a linkage rod, which is rotatably connected to the adjacent slider. A return spring is arranged inside the slider and between the slider and the slider. The rotating seat has symmetrically distributed adjusting screws that are rotatably arranged inside. The adjusting screws are threadedly connected to the adjacent sliders. The rotating seat has a dual-axis motor inside. The output shaft of the dual-axis motor is fixed to the adjacent adjusting screw through a coupling.

[0007] As a further improvement of this utility model, symmetrically distributed motors are provided on the outside of the roller box. The output shaft of the motor is fixed to the adjacent rotating seat by a coupling. Motors are provided inside the motor seats. The output shaft of the motors is fixed to the adjacent roller shaft by a coupling.

[0008] As a further improvement of this utility model, the impact box is equipped with symmetrically distributed hammer rollers for rotation, and the impact box is equipped with symmetrically distributed motors on the outside. The output shaft of the motors is fixed to the hammer rollers by couplings.

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

[0010] Firstly, the output shafts of the dual-shaft motors drive the adjusting screws connected to them to rotate. Through the cooperation of the linkage rod and the return spring, the slide rod slides inside the slide cylinder, adjusting the length of the slide rod extension and the distance between the drum shaft and the second screen, thereby controlling the degree of material crushing by the drum shaft.

[0011] Secondly, the second motor drives the rotating seat connected to it to swing back and forth, and the output shaft of the third motor drives the roller shaft connected to it to rotate, so that the roller shaft moves continuously in the roller box during the rotation. The output shaft of the dual-shaft motor drives the adjusting screw connected to it to rotate, controlling the distance between the roller shaft and the screen second, so that the roller shaft, which moves continuously in the roller box during the rotation, is in the optimal position for crushing materials.

[0012] Thirdly, by rotating the hammer roller and the drum shaft, the material is further crushed by the drum shaft that moves continuously inside the roller box during the rotation process, thereby effectively ensuring the crushing effect and efficiency.

[0013] Fourth, both mesh one and mesh two are made of composite ceramic materials, which can resist the impact and wear of materials during crushing. 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] As shown in Figures 2 and 4, the system includes a roller box 102, an impact box 103 on the upper side of the roller box 102, a feed hopper 104 at the upper end of the impact box 103, symmetrically distributed rotating seats 201 rotatably arranged inside the roller box 102, symmetrically distributed slide cylinders 202 slidably arranged on the lower side of each rotating seat 201, and slide rods 203 slidably arranged inside each slide cylinder 202. An L-shaped seat 204 is provided at the bottom end of each slide rod 203 on one side, and a motor seat 205 is provided at the bottom end of each slide rod 203 on the other side. A roller shaft 206 is rotatably arranged between the motor seat 205 and the adjacent L-shaped seat 204. An adjustment module is also provided on the rotating seat 201 to adjust the extension length of the slide rod 203. A first strainer 107 is provided at the bottom inside the impact box 103, and a second strainer 108 is provided at the bottom inside the roller box 102. Both strainers 107 and second strainer 108 are made of composite ceramic material.

[0022] As shown in Figures 3 and 4, the adjustment module includes a connecting box 207 symmetrically arranged on the lower side of the rotating seat 201. Symmetrically distributed sliders 208 are slidably arranged inside the rotating seat 201. A linkage rod 209 is rotatably arranged on the lower side of each slider 208. The linkage rods 209 are rotatably connected to adjacent slide rods 203. A return spring 210 is provided between the inside of the slide cylinder 202 and the slide rod 203. Symmetrically distributed adjusting screws 211 are rotatably arranged inside the rotating seat 201. The adjusting screws 211 are threadedly connected to adjacent sliders 208. A dual-axis motor 212 is provided inside the rotating seat 201. The output shaft of the dual-axis motor 212 is fixed to the adjacent adjusting screw 211 via a coupling.

[0023] As shown in Figures 1 and 2, symmetrically distributed motors 212 are provided on the outside of the roller box 102. The output shaft of motor 212 is fixed to the adjacent rotating seat 201 by a coupling. Motors 3 are provided inside the motor seat 205. The output shaft of motor 3 is fixed to the adjacent roller shaft 206 by a coupling.

[0024] As shown in Figures 2 and 4, the impact box 103 is equipped with symmetrically distributed hammer rollers 105, and the impact box 103 is equipped with symmetrically distributed motors 106 on the outside. The output shaft of the motors 106 and the hammer rollers 105 are fixed by couplings.

[0025] In use, motor 106 drives the hammer rollers 105 connected to it to rotate, thereby causing the hammer rollers 105 on both sides inside the impact box 103 to rotate synchronously in opposite directions; the output shaft of motor 3 drives the roller shaft 206 connected to it to rotate, thereby causing the roller shafts 206 on both sides inside the roller box 102 to rotate synchronously in opposite directions.

[0026] Motor 212 drives the rotating seat 201 connected to it to swing back and forth, causing the two rotating seats 201 on both sides to rotate towards each other or away from each other. This causes the rotating seat 201 to drive the rotating roller shaft 206 to swing towards each other or away from each other via the slide rod 203. During the rotation of the rotating seat 201, the output shaft of the dual-axis motor 212 drives the adjusting screw 211 connected to it to rotate. By adjusting the thread relationship between the adjusting screw 211 and the slider 208, the slider 208 is driven to slide inside the rotating seat 201. During the movement of the slider 208: the slider 208 rotates with the linkage rod 209, and the linkage rod 209 rotates with the slide rod 203. The rotation between the two parts causes the return spring 210 to push the slide bar 203 downwards. Through the cooperation of the linkage rod 209 and the return spring 210, the slide bar 203 slides inside the slide cylinder 202. By controlling the forward and reverse rotation of the output shaft of the dual-axis motor 212, the slide bar 203 is extended or retracted. This controls the distance between the drum shaft 206 and the second screen 108 during the swinging of the drum shaft 206 towards or away from each other, so that the drum shaft 206 is in the optimal position for crushing the material. During the crushing process, the degree of material crushing by the drum shaft 206 can be controlled by adjusting the extension length of the slide bar 203 through the dual-axis motor 212, thus better adapting to the needs of material crushing.

[0027] The material is poured from the feed hopper 104 into the impact box 103. The material is initially crushed by the impact force of the rotating hammer roller 105. After crushing, the material is leaked from the screen 107 into the roller box 102. The material is further crushed by the roller shaft 206 that moves continuously in the roller box 102 during the rotation process, which can effectively ensure the crushing effect and efficiency.

[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.
