Therefore, the utility model provides a small pair of roll crusher to solve the above problems. UTILITY MODEL CONTENTS

[0017] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figs. 1 to 4This utility model provides a technical solution: a small double-roll crusher, including: a frame 1, a fixed plate 14 and a conical part 12. The upper end of the frame 1 is detachably equipped with a feeding hopper 2. When it is necessary to inspect the inside of the frame 1, the feeding hopper 2 can be disassembled to facilitate observation of the internal condition. The lower end of the frame 1 is provided with a discharge port 3. The crushed material will flow out from the discharge port 3. The two sides of the frame 1 are provided with sliding grooves 4. Two adjusting screws 5 are threadedly connected to one side of the frame 1. The distance between the first pressure roller 15 and the second pressure roller 16 can be adjusted through the sliding grooves 4, thereby limiting the size of the crushed material.

[0019] Both pressure roller 15 and pressure roller 2 16 have a rotating shaft 8 fixedly connected to their inner walls. The rotating shaft 8 of pressure roller 2 16 passes through and is rotatably connected to the frame 1. By connecting the rotating shaft 8 to a motor, it is easy to drive pressure roller 2 16 or pressure roller 15 to rotate. The two ends of the rotating shaft 8 of pressure roller 15 are respectively located in the slide groove 4. Two fixing blocks 9 are rotatably connected to the surface of each rotating shaft 8. The fixing blocks 9 can prevent pressure roller 15 or pressure roller 2 16 from directly contacting the frame 1. One side of the fixing block 9 contacts the inner wall of the frame 1. The other side contacts either pressure roller 15 or pressure roller 2 16 to protect the entire device. One side of the fixed block 9 that contacts pressure roller 15 is rotatably connected to one end of the adjusting screw 5. The other end of the adjusting screw 5 passes through the frame 1 and is threadedly connected to a fixing nut 6. The adjusting screw 5 is threadedly connected to the frame 1. By rotating the adjusting screw 5, the rotating shaft 8 can slide along the slide groove 4, thereby changing the distance between pressure roller 15 and pressure roller 2 16. The position of the fixed block 9 can be fixed by the fixing nut 6.

[0020] The feed hopper 10 is fixedly connected to the inner wall of the frame 1. A vibrating screen 11 is detachably installed at the lower end of the feed hopper 10. The surface of the vibrating screen 11 has a large number of mesh holes. Two fixing plates 14 are slidably connected to the lower end of the feed hopper 10. A fixing plate 14 is fixedly connected to each side of the screen plate 13. The height of the conical member 12 can be adjusted through the fixing plates 14. Several conical members 12 are fixedly connected to the upper end of the screen plate 13. The number of conical members 12 is the same as the number of mesh holes on the surface of the vibrating screen 11. There is a conical member 12 directly below each mesh hole. As the conical part 12 rises, it gradually passes through the mesh. At this time, the distance between the surface of the conical part 12 and the inner wall of the mesh gradually decreases, so that the diameter of the particles that can pass through the mesh also gradually decreases, thereby adjusting the diameter of the mesh of the vibrating screen 11. The lower surface of the adjusting rod 7 is threaded, and the adjusting rod 7 is rotatably connected to the frame 1 and threadedly connected to the fixed plate 14. When the adjusting rod 7 is rotated, the height of the screen plate 13 can be adjusted. The upper end of the adjusting rod 7 passes through the upper end of the frame 1, which facilitates adjustment during machine operation.

[0021] When this device is working, the pressure roller 15 is adjusted to the designated position, and the conical part 12 is adjusted to a suitable height by adjusting the adjusting rod 7. The material is then fed into the hopper 2. After crushing, it will be screened by the vibrating screen 11. After screening, non-compliant particles will remain between the conical part 12 and the vibrating screen 11. Then, the container is replaced at the discharge port 3 and the height of the conical part 12 is lowered. At this time, the mesh size increases the particle diameter, and non-compliant particles can flow out through the mesh for further crushing. The device is easy to operate, and the mesh size adjustment of the vibrating screen 11 is simple and convenient to use, which improves the overall working efficiency.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
