The bottom of the grinding feed box has an integrally formed arc-shaped grinding section and a straight material discharge section. Grinding rollers are symmetrically arranged on both sides of the inner cavity of the arc-shaped grinding section, and grinding rollers are equally spaced below the center symmetry line of the two grinding rollers. Grinding rollers are synchronously connected via a grinding transmission mechanism. A feed inlet communicating with the straight material discharge section is opened on the top wall of the base box. The bottom cavity of the base box is divided by a vertical partition into a storage cavity for undersize material and a storage cavity for oversize material on the left and right sides. A screen plate is installed at the top of the undersize material storage cavity. The top cavity of the base box is a mixing chamber. This technical solution has a simple structure, mixes materials evenly and efficiently, and helps improve mixing quality, thus meeting user needs. However, this device does not completely grind the raw materials, and the raw materials are sometimes compressed into lumps during the grinding process. Summary of the Invention

[0003] The purpose of this utility model is to provide a raw material grinding device that solves the problem that existing raw material grinding devices do not grind and crush raw materials completely, and that the raw materials in the device are squeezed into blocks during the grinding process.

[0004] To achieve the above objectives, this utility model provides a raw material grinding device, including a vessel body. A vessel cover is fixedly connected to the upper end of the vessel body. A motor is fixedly installed in the middle of the upper end of the vessel cover. The output end of the motor passes through the vessel cover and is rotatably connected to the vessel cover. A main shaft is welded to the lower end of the output end. A control mechanism is provided on the main shaft. A cylinder is fixedly sleeved inside the vessel body. A crushing mechanism is provided on the main shaft. A hanging plate is provided on the outer side of the cylinder. The cylinder and the main shaft are rotatably connected. A auger is provided on the outer side of the main shaft. The auger and the cylinder are rotatably connected. A feed inlet is opened inside the cylinder wall. A discharge outlet is opened inside the cylinder wall.

[0005] The principle of this invention is as follows: Raw materials are poured into the reactor body, the motor is started, the motor drives the main shaft to rotate, the main shaft drives the auger to rotate, the raw materials in the reactor body enter the cylinder from the feed port, the auger conveys the raw materials, and the raw materials are screened during the conveying process, so that large particles are thrown out from the discharge port, and then ground again, so that the raw materials are crushed more completely and the particle size is more uniform. The motor drives the turntable to rotate, the turntable drives the hanging plate to rotate, the hanging plate drives the grinding head to rotate. At the same time, the motor starts, the motor drives the gear to rotate, the gear drives the rack to move, the rack drives the turntable to move, the turntable drives the hanging plate to move up, and thus the grinding head moves up until the teeth of the gear and the rack disengage. The grinding head falls under its own weight and hammers the raw materials. During the process of the grinding head and the bottom of the reactor body disengaging, the spring acts on the connecting ring, so that the scraper can slide and extend within the grinding head, thus scraping the raw materials at the bottom of the reactor body, preventing the raw materials from being compacted, and ensuring the crushing effect of the device on the raw materials.

[0006] The beneficial effects of this utility model are as follows: the main shaft is driven to rotate by a motor, which in turn causes the auger to rotate, so that the raw material at the bottom of the vessel is conveyed by the auger. During the conveying process, the raw material is screened, so that large particles are thrown out from the discharge port and ground again, making the raw material more completely crushed and the particle size more uniform. The turntable is driven to rotate by a motor, and the gear is driven to rotate by a motor, which in turn causes the rack to move, so that the crushing mechanism can move up and down to hammer and grind the raw material, thereby improving the crushing efficiency.

[0007] The spring acts on the connecting ring, allowing the scraper to slide and extend within the grinding head, thereby scraping the raw material at the bottom of the vessel, preventing it from being compacted, and ensuring the device's pulverizing effect on the raw material.

[0008] Furthermore, the control mechanism includes a turntable, rack, sliding pin, motor, and gear. The turntable is slidably connected to the outer side of the main shaft, and the turntable is fixedly connected to the hanging plate. The rack is slidably connected to the inside of the vessel lid. The motor is fixedly installed at the rear end of the vessel body, and the motor's rotating shaft passes through the vessel body and is rotatably connected to it. A gear is fixedly connected to the front end of the rotating shaft, and the gear meshes with the rack. The motor drives the main shaft to rotate, which in turn causes the auger to rotate, allowing the raw material at the bottom of the vessel body to be conveyed by the auger. During the conveying process, the raw material is screened, causing large particles to be thrown out of the discharge port for further grinding, making the raw material more completely crushed and the particle size more uniform. The motor drives the turntable to rotate, and the motor drives the lever gear to rotate, which in turn causes the rack to move, allowing the crushing mechanism to move up and down to hammer and grind the raw material, improving the crushing efficiency.

[0009] Furthermore, a sliding pin is fixedly connected to the lower right end of the rack, and the sliding pin is slidably connected to the turntable. The movement of the turntable is controlled by the sliding pin.

[0010] Furthermore, the pulverizing mechanism includes a grinding head, a connecting ring, a scraper, a spring, and a guide rod. The grinding head is fixedly connected to the lower end of the hanging plate, and the connecting ring is movably connected to the outer side of the cylinder. A scraper is welded to the lower end of the connecting ring. The scraper is slidably connected to the vessel body and the grinding head. A spring is provided on the outer side of the cylinder. The spring acts on the connecting ring, allowing the scraper to slide and extend within the grinding head, thereby scraping the raw material at the bottom of the vessel body, preventing compaction, and ensuring the pulverizing effect of the device.

[0011] Furthermore, the grinding head and the cylinder are movably connected, and the grinding head and the reactor body are slidably connected. The grinding head is used to pulverize the raw materials.

[0012] Furthermore, one end of the spring is fixedly connected to the hanging plate, and the other end of the spring is fixedly connected to the connecting ring. The spring design facilitates the repositioning of the connecting ring.

[0013] Furthermore, a guide rod is welded to the upper end of the connecting ring, and the guide rod is slidably connected to the hanging plate. The guide rod guides the movement of the connecting ring. Attached Figure Description

A control mechanism 5 is provided on the main shaft 4. A cylinder 6 is fixedly sleeved inside the vessel body 1. A crushing mechanism 7 is provided on the main shaft 4. A hanging plate 8 is provided on the outside of the cylinder 6. The cylinder 6 and the main shaft 4 are rotatably connected. A auger 9 is provided on the outside of the main shaft 4. The auger 9 and the cylinder 6 are rotatably connected. A feed inlet 10 is opened in the inner wall of the cylinder 6. A discharge outlet 11 is opened in the inner wall of the cylinder 6.

[0021] like Figure 2 As shown, the control mechanism 5 includes a turntable 51, a rack 52, a sliding pin 53, a motor 54, and a gear 55. The turntable 51 is slidably connected to the outer side of the main shaft 4, and the turntable 51 is fixedly connected to the hanging plate 8. The rack 52 is slidably connected to the inside of the vessel cover 2, and the sliding pin 53 is fixedly connected to the lower right end of the rack 52. The sliding pin 53 is slidably connected to the turntable 51. The movement of the turntable 51 is controlled by the sliding pin 53. The motor 54 is fixedly installed at the rear end of the vessel body 1. The rotating shaft of the motor 54 passes through the vessel body 1 and is rotatably connected to the vessel body 1. The front end of the rotating shaft is fixedly connected to... There is a gear 55, which meshes with a rack 52. The motor 3 drives the main shaft 4 to rotate, which in turn drives the auger 9 to rotate. The raw material at the bottom of the vessel 1 is conveyed by the auger 9. During the conveying process, the raw material is screened, and large particles are thrown out from the discharge port 11. The material is then ground again, making the raw material more completely crushed and the particle size more uniform. The motor 3 drives the turntable 51 to rotate, and the motor 54 drives the rod gear 55 to rotate, which in turn drives the rack 52 to move. This allows the crushing mechanism 7 to move up and down to hammer and grind the raw material, improving the crushing efficiency.

[0022] like Figure 2 , Figure 4As shown, the crushing mechanism 7 includes a grinding head 71, a connecting ring 72, a scraper 73, a spring 74, and a guide rod 75. The lower end of the hanging plate 8 is fixedly connected to the grinding head 71. The grinding head 71 is movably connected to the cylinder 6 and slidably connected to the vessel body 1. By setting the grinding head 71, the raw materials are crushed. The outer side of the cylinder 6 is movably connected to the connecting ring 72. The lower end of the connecting ring 72 is welded to the scraper 73. The scraper 73 is slidably connected to the vessel body 1 and the grinding head 71. A spring 74 is set on the outer side of the cylinder 6. One end of spring 74 is fixedly connected to the hanging plate 8, and the other end of spring 74 is fixedly connected to the connecting ring 72. By setting spring 74, the connecting ring 72 can be easily reset. A guide rod 75 is welded to the upper end of the connecting ring 72. The guide rod 75 is slidably connected to the hanging plate 8. By setting guide rod 75, the movement of the connecting ring 72 is guided. By the action of spring 74 on the connecting ring 72, the scraper 73 can slide and extend within the grinding head 71, thereby scraping the raw material at the bottom of the vessel 1, preventing the raw material from being compacted, and ensuring the crushing effect of the device on the raw material.

[0023] The specific implementation process of this utility model is as follows: Raw materials are poured into the reactor body 1, and the motor 3 is started. The motor 3 drives the main shaft 4 to rotate, which in turn drives the auger 9 to rotate. The raw materials in the reactor body 1 enter the cylinder 6 through the feed inlet 10, allowing the auger 9 to convey the raw materials. During this conveying process, the raw materials are screened, causing large particles to be ejected from the discharge outlet 11. The materials are then ground again, resulting in more complete pulverization and more uniform particle size. The motor 3 drives the turntable 51 to rotate, which in turn drives the hanging plate 8 to rotate. The hanging plate 8 then drives the grinding head 71 to rotate. Simultaneously, the motor 54 is started. 54 drives gear 55 to rotate, gear 55 drives rack 52 to move, rack 52 drives turntable 51 to move, turntable 51 drives hanging plate 8 to move upward, thereby causing grinding head 71 to move upward until the teeth of gear 55 disengage from rack 52. Grinding head 71 falls under its own weight to hammer the raw material. During the process of disengagement and retraction between grinding head 71 and bottom of vessel 1, spring 74 acts on connecting ring 72, allowing scraper 73 to slide and extend within grinding head 71, thereby scraping the raw material at bottom of vessel 1, preventing the raw material from being compacted, and ensuring the crushing effect of the device on the raw material.

[0024] The motor 3 drives the main shaft 4 to rotate, which in turn causes the auger 9 to rotate, so that the raw material at the bottom of the vessel 1 is conveyed by the auger 9. During the conveying process, the raw material is screened, so that large particles are thrown out from the discharge port 11 and ground again, making the raw material more completely crushed and the particle size more uniform. The motor 3 drives the turntable 51 to rotate, and the motor 54 drives the gear 55 to rotate, which in turn causes the rack 52 to move, so that the crushing mechanism 7 can move up and down to hammer and grind the raw material, thereby improving the crushing efficiency.

[0025] The spring 74 acts on the connecting ring 72, allowing the scraper 73 to slide and extend within the grinding head 71, thereby scraping the raw material at the bottom of the vessel 1, preventing the raw material from being compacted, and ensuring the crushing effect of the device on the raw material.
