The fan 101 is located on one side inside the machine base 1, and the air outlet pipe 102 is located at the air outlet end of the fan 101, with one end of the air outlet pipe 102 penetrating to one side of the machine base 1. This allows for the extraction of dust from inside the pulverizing chamber 2, facilitating dust collection and improving the pulverizer's environment. The pulverizing chamber 2 includes a main shaft 202, a handwheel 203, a rotating shaft 204, a gear 205, and a toothed gear 206. The main shaft 202 is located inside the pulverizing chamber 2. The handwheel 203 is located above the top of the pulverizing chamber 2. The rotating shaft 204 is located at the bottom end inside the handwheel 203 and penetrates into the interior of the pulverizing chamber 2. The gear 205 is located on the rotating shaft 206. At the bottom of 04, the handwheel 203 can drive the gear 205 to rotate via the rotating shaft 204. Multiple sets of teeth 206 are evenly arranged on the outside of the main shaft 202, and the teeth 206 mesh with the gear 205 to realize the transmission of power. The main shaft 202 can be linearly adjusted, and the distance between the moving grinding disc 208 and the fixed grinding disc 201 can be adjusted. The front end of the crushing chamber 2 is provided with a discharge port 103. The top of the crushing chamber 2 and the discharge port 103 are both provided with dust covers 104 to prevent dust and improve the dust prevention effect of the crusher. The front end of the crushing chamber 2 is provided with a fixed grinding disc 201. One end of the crushing chamber 2 is provided with a mounting plate 207. The end of the mounting plate 207 away from the crushing chamber 2 is provided with a moving grinding disc 208. The moving grinding disc 208 is installed on one end of the main shaft 202 through the mounting plate 207.

[0026] Please refer to this carefully. Figure 1 and Figure 4 The crushing chamber 2 is equipped with a transmission component 3 at the end away from the discharge port 103. A motor 301 is provided on one side of the top of the machine base 1 to provide kinetic energy for the crusher. Through the transmission component 3, the moving grinding disc 208 at one end of the main shaft 202 can be driven to rotate, which facilitates the crushing of materials.

[0027] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3The bottom of the crushing chamber 2 is equipped with a connecting pipe that extends into the machine base 1, and one end of the connecting pipe is connected to the exhaust port of the fan 101 to extract and collect dust from inside the crushing chamber 2. The crushing chamber 2 is connected to the machine base 1 by bolts for fixed installation. Multiple bearing seats are located at the rear end inside the crushing chamber 2. The main shaft 202 is rotatably connected to the crushing chamber 2 through the bearing seats, which makes the rotation of the main shaft 202 more stable. A positioning bolt is located on the outer side of the handwheel 203 for positioning, preventing the handwheel 203 from rotating. A positioning mounting hole is provided inside the handwheel 203, and the rotating shaft 204 is detachably connected to the handwheel 203 through the positioning mounting hole, allowing for installation between the rotating shaft 204 and the handwheel 203. Gear 2... 05 is fixedly connected to the handwheel 203 via the rotating shaft 204. The handwheel 203 can drive the gear 205 to rotate. The main shaft 202 is connected to the rotating shaft 204 via the toothed end 206 and the gear 205 to realize the transmission of power. It can drive the main shaft 202 to perform linear motion, thereby adjusting the initial distance between the moving grinding disc 208 and the fixed grinding disc 201. The crushing chamber 2 is equipped with a bearing located at the position of the rotating shaft 204, which makes the rotation effect of the bearing 204 more stable. The fixed grinding disc 201 is connected to the crushing chamber 2 by bolts, which allows the fixed grinding disc 201 to be disassembled and assembled from the crushing chamber 2. The moving grinding disc 208 is connected to the mounting plate 207 by bolts, and the moving grinding disc 208 can be installed on one end of the main shaft 202 via the mounting plate 207.

[0028] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4 Inside the machine 1, below the crushing chamber 2, there is a receiving drawer for holding crushed material, which facilitates the collection of crushed material. The bottom of the crushing chamber 2 has a discharge port that extends into the machine 1 to discharge the crushed material. The transmission component 3 consists of two sets of pulleys, a transmission belt, and a protective cover. The output end of the motor 301 is connected to one set of pulleys, and one end of the main shaft 202 is connected to the other set of pulleys to realize the transmission of power, which enables the motor 301 to drive the main shaft 202 to rotate.

[0029] Working Principle: Before use, the dust collection bag can be connected to the air outlet pipe 102 via a connecting clamp. During use, remove the positioning bolts and manually turn the handwheel 203. This, via the rotating shaft 204, drives the gear 205 to rotate. The gear 205 meshes with the toothed jaw 206, causing the main shaft 202 to move axially in a linear motion. This allows adjustment of the distance between the fixed grinding disc 201 and the moving grinding disc 208, thus adjusting the degree of grinding and improving the performance of the disc crusher. The crushed material can be discharged through the discharge port 103. The material is conveyed into the crushing chamber 2. The motor 301 and the transmission assembly 3 drive the main shaft 202 to rotate, thereby driving the moving grinding disc 208 to rotate. Through the cooperation of the fixed grinding disc 201 and the moving grinding disc 208, the material is crushed. Two sets of dust covers 104 can seal the top of the crushing chamber 2 and the discharge port 103 to prevent dust from escaping. The crushed material can be received by the receiving drawer. The dust in the crushing chamber 2 is extracted into the dust collection bag by the fan 101 and the connecting pipe, so that the crusher can be used more effectively.
