[0002] A crusher-grinder is a device specifically designed for crushing and grinding materials. It usually consists of one or more crushing units and one or more grinding units. Through mechanical force, it breaks large pieces of material into small pieces, and then further grinds the small pieces of material to achieve the desired particle size.

The opposite sides of the two sets of moving blocks are equipped with threaded rods through bearings, and the threaded rods are moved in the sleeve rod by rotating the handle to move the moving block, thereby adjusting the gap between the rolling plate and the crushing roller, so that the crushing intensity of the ore can be adjusted. At the same time, a scale is provided, which can more accurately adjust the gap between the rolling plate and the crushing roller, thereby improving the fineness of ore crushing, so that the crushed ore can be used in different engineering fields.

[0004] While the above technical solution can adjust the crushing force of the ore by adjusting the gap between the rolling plate and the crushing roller, the ore generates vibration when it is squeezed and crushed between the rolling plate and the crushing roller. This vibration may be transmitted to the threaded rod and the sleeve rod through the rolling plate. Consequently, the connection between the threaded rod and the sleeve rod, when subjected to vibration for a long time, may cause increased friction and wear on the threaded surface, thereby reducing the tightness of the connection. This may lead to failure of the connection between the threaded rod and the sleeve rod, thus affecting the normal operation of the entire equipment. Therefore, we provide a crushing and grinding machine that can easily adjust the crushing degree. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] The utility model provides a technical solution: Figures 1-6 As shown, in this embodiment, a crushing and grinding machine that is convenient for adjusting the degree of crushing includes: an adjusting mechanism 1, which includes a crushing box 11, and the threaded grooves on both sides of the crushing box 11 are threadedly connected with adjusting screws 12, and the opposite ends of the two adjusting screws 12 are rotatably connected to rolling plates 13, and the bottoms of the two rolling plates 13 are fixedly connected to four sliders 14, and support platforms 15 are provided on both sides of the crushing box 11. The tops of the two support platforms 15 are provided with a slide groove 16 corresponding to the slider 14, and the opposite sides of the two support platforms 15 are provided with a slide groove 2 18, and a leak plate 17 is provided between the two support platforms 15, and the opposite sides of the two support platforms 15 are fixedly connected to the two sides of the inner wall of the crushing box 11 respectively, and the outer side of the slider 14 is slidably connected to the inner wall of the slide groove 16, and the two sides of the leak plate 17 are slidably connected to the inner walls of the two slide grooves 2 18 respectively. , a plurality of movable rods 19 are provided on one side of the two rolling plates 13 close to the inner wall of the crushing box 11, and a fixed tube 110 is provided on the end of the plurality of movable rods 19 away from the rolling plate 13, one end of the movable rod 19 is fixedly connected to the side of the rolling plate 13 away from the grinding roller 34, the outside of the movable rod 19 away from the end of the rolling plate 13 is slidably connected to the inner wall of the fixed tube 110, the outside of the fixed tube 110 is fixedly connected to the slot opened on the inner wall of the crushing box 11, and a plurality of fixed tubes 110 are provided with spring pieces 111 inside, one end of the spring piece 111 is fixedly connected to the end of the movable rod 19 away from the rolling plate 13, and the other end of the spring piece 111 is fixedly connected to the end of the inner wall of the fixed tube 110 away from the movable rod 19, the inner wall opened at the top of the crushing box 11 is docked with a feed port 41, a collecting mechanism 2 is provided on the bottom side of the crushing box 11, and a crushing mechanism 3 is provided on one side of the crushing box 11.

[0028] In this embodiment, when the staff needs to use the device to adjust its crushing degree, they can rotate the adjusting screws 12 provided on both sides of the crushing box 11. Therefore, when the adjusting screws 12 are rotated, the rolling plate 13 will be driven to move horizontally. At the same time, the slider 14 provided at the bottom of the rolling plate 13 will slide in the slide 16 to ensure that the rolling plate 13 moves more smoothly, thereby changing the distance between the rolling plate 13 and the grinding roller 34, thereby achieving the effect of adjusting the crushing degree. When the ore is crushed between the rolling plate 13 and the grinding roller 34, a vibration will be generated. The vibration force will be transmitted to the movable rods 19 along with the rolling plate 13. Therefore, when the movable rods 19 are subjected to the vibration force, they will slide and sink toward the inner wall of the fixed tube 110, and squeeze the shrapnel 111 at the same time. The shrapnel 111 will release the vibration force slowly to avoid the vibration force causing increased friction and wear at the connection between the adjusting screw 12 and the threaded groove opened in the crushing box 11. When the ore is crushed, it will fall onto the leakage plate 17. Those ores that meet the crushing standards will pass through the leakage plate 17 and fall into the collection box 21, while the ores that have not passed through the leakage plate 17 need to continue to be crushed and ground.

[0029] like Figure 2-Figure 6 As shown, the collecting mechanism 2 includes a collecting box 21, a ramp 22 is fixedly connected to the inside of the collecting box 21, a plurality of pulleys 23 are fixedly installed at the bottom of the collecting box 21, three slide rails 24 are opened on the bottom side of the inner wall of the crushing box 11, and the bottom of the pulley 23 is slidably connected to the inner wall of the slide rail 24.

[0030] In this embodiment, the crushed and ground ores can be collected and processed through the collection box 21, so when the ore falls on the slope 22, the slope 22 can prevent the crushed ores from piling up. When the ore fragments in the collection box 21 need to be used, the pulley 23 and the slide rail 24 can facilitate the staff to more easily take the collection box 21 out of the crushing box 11, reducing the labor intensity of the staff during the operation.

[0031] like Figure 1-Figure 3 As shown, the crushing mechanism 3 includes a motor 31, a support plate 42 is fixedly connected to one side of the crushing box 11, the top of the support plate 42 is fixedly connected to the outside of the motor 31, the output end of the motor 31 passes through a slot opened on one side of the crushing box 11 and is fixedly connected to the inner surface of gear 1 32, the teeth of gear 1 32 are engaged with the teeth of gear 2 33, and the sides of gear 1 32 and gear 2 33 away from the motor 31 are fixedly connected with grinding rollers 34, and the ends of the two grinding rollers 34 away from gear 1 32 are rotatably connected to the side of the inner wall of the crushing box 11 away from the motor 31, and the top side of the inner wall of the crushing box 11 is fixedly connected to a dividing plate 35.

[0032] In this embodiment, the ore to be crushed is fed into the crushing box 11 through the feed port 41, and then the ore is divided to both sides of the crushing box 11 through the dividing plate 35, ensuring that the ore is between the rolling plate 13 and the grinding roller 34. After starting the motor 31, the gear 1 32 and the grinding roller 34 on one side thereof will be driven to rotate. Since the teeth of the gear 1 32 and the tooth grooves of the gear 2 33 are engaged, the gear 2 33 will rotate with the rotation of the gear 1 32, and then the grinding roller 34 on the side of the gear 2 33 will also rotate.

[0033] The utility model provides a crushing and grinding machine which is convenient for adjusting the degree of crushing. The specific working principle is as follows:

[0034] When the staff needs to adjust the crushing degree of the device, it can be achieved by rotating the adjusting screws 12 on both sides of the crushing box 11. The design of these adjusting screws 12 makes it possible for the rolling plate 13 to move horizontally when they are rotated. At the same time, the slider 14 provided at the bottom of the rolling plate 13 will also slide in the slide 16, thereby changing the distance between the rolling plate 13 and the grinding roller 34. This design allows the staff to adjust the crushing degree as needed to achieve the desired effect. When the ore to be crushed is put into the crushing box 11 through the feed port 41, the dividing plate 35 will divide the ore to both sides of the crushing box 11, ensuring that the ore is between the rolling plate 13 and the grinding roller 34. This process ensures that the ore can be evenly crushed, thereby improving the crushing efficiency. Once the motor 31 is started, it will drive the gear 1 32 and the grinding roller 34 on one side of it to rotate. Due to the teeth of the gear 1 32 The teeth of gear 2 33 are meshed with the tooth grooves of gear 2, and gear 2 33 will rotate as gear 1 32 rotates. This mutually meshing design allows the grinding roller 34 on one side of gear 2 33 to rotate as well. When the ore is crushed between the rolling plate 13 and the grinding roller 34, a vibration force is generated. This vibration force will act on these movable rods 19 as it is transmitted by the rolling plate 13. Therefore, when the movable rods 19 are subjected to the vibration force, they will slide and sink toward the inner wall of the fixed tube 110. At the same time, this vibration force will also squeeze the shrapnel 111. The function of the shrapnel 111 is to release these vibration forces to protect other parts of the equipment from excessive vibration. After the ore is crushed, it will fall onto the leakage plate 17. The design of the leakage plate 17 allows only the ore that meets the crushing standards to pass through and fall into the collection box 21, while those ores that have not passed through the leakage plate 17 need to continue the crushing and grinding process.

[0035] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
