[0002] Rice, also known as paddy rice, is a food made from paddy after processes such as cleaning, hulling, rice milling, and finished product finishing. When processing rice, it is necessary to mill and remove the husk from it.

[0003] For example, an efficient rice milling device with the authorization announcement number of "CN208912146U" controls the working space of two rice milling rollers, making the rice milling effect more efficient and of high quality. At the same time, the rice milling chamber can be cleaned regularly, extending the service life of the device and having strong practicability. However, for this efficient rice milling device, when filtering rice with a filter screen, when the filter screen is blocked by the filtered impurities, the filter screen will reduce the filtering speed of rice, thereby reducing the working efficiency. Also, for this efficient rice milling device, when adsorbing metal impurities in rice, if too much rice is fed, the rice will pile up together, resulting in incomplete adsorption of metal impurities in rice, thereby reducing the working quality. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that when the filter screen is blocked by the filtered impurities, the filter screen will reduce the filtering speed of rice, thereby reducing the working efficiency, and if too much rice is fed, the rice will pile up together, resulting in incomplete adsorption of metal impurities in rice, thereby reducing the working quality, and to propose an efficient rice milling device for rice milling.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] Design an efficient rice milling device for rice milling, including a box body. Knocking mechanisms are installed at the front end and the rear end of the box body. A material control mechanism is installed on the left side of the upper end of the box body. A feed inlet is arranged at the upper end of the box body, and a discharge outlet is arranged at the lower end of the box body. The inner wall of the box body is attached to a filter plate through a sealing ring. A vacuum cleaner is installed on the inner wall of the box body. Two rice milling rollers are installed on the upper inner wall of the box body. The inner walls on both sides of the box body are bolted and threaded together.

[0007] Preferably, the material control mechanism includes a first shell. The outer wall of the first shell is fixedly connected to the box body. The first shell is fixedly connected to a first motor through a bracket. The output shaft of the first motor is rotatably connected to the first shell through a bearing. The output shaft of the first motor is connected to a gear through a speed reducer. The gear is rotatably connected to the first shell through a rotating shaft. The upper end of the gear is engaged with a first rack. The right end of the first rack is fixedly connected to a first plate body.

[0008] Preferably, the lower end of the gear meshes with the second rack, the right end of the second rack is fixedly connected to the second plate body, the outer walls of the first rack and the second rack are both slidably connected to the first housing, the outer wall of the first plate body is respectively attached to the first housing and the feed inlet through a sealing ring, and the outer wall of the second plate body is respectively attached to the first housing and the feed inlet through a sealing ring.

[0009] Preferably, the knocking mechanism includes a second housing, the outer wall of the second housing is fixedly connected to the box body, the second housing is fixedly connected to the second motor through a bracket, the output shaft of the second motor is connected to the rotating shaft of the rod body through a coupling, the rod body is rotatably connected to the second housing through the rotating shaft, the end of the rod body is rotatably connected to the roller, and the outer wall of the roller is attached to the cross plate.

[0010] Preferably, a spring is provided on the outer wall of the cross plate, both ends of the spring are fixedly connected to the second housing and the cross plate respectively, and a vertical block is fixedly connected to the upper end of the cross plate.

[0011] Preferably, the right end of the vertical block is slidably connected to the second housing, the outer wall of the vertical block is respectively attached to the second housing and the box body through a sealing ring, and the upper end of the vertical block is attached to the filter plate.

[0012] An efficient rice milling device for rice milling proposed by the present utility model has the beneficial effects that: through the cooperation of the material control mechanism and the box body, the first motor drives the gear to rotate, the gear drives the first rack to move leftward and then drives the first plate body to move. While the first plate body moves leftward, the gear will drive the second rack to move and then drive the second plate body to move rightward. After the first plate body moves to the extreme position, the right end of the second plate body will be clamped with the inner wall of the feed inlet. After the right end of the second plate body is clamped with the inner wall of the feed inlet, turn off the first motor. As the first plate body moves, the rice on the first plate body will be introduced onto the second plate body. After the rice on the second plate body reaches the required amount, reverse the first motor, the second plate body moves leftward and separates from the inner wall of the feed inlet.

After the rice on the second plate body reaches the required amount, the second plate body resets and guides the rice on the second plate body into the box body, and the first plate body blocks the rice in the feed inlet, so that the rice enters the box body quantitatively, thereby preventing the rice from accumulating excessively on the filter plate and affecting the filtering effect of the rice, and thus improving the working efficiency.

[0013] Through the cooperation of the knocking mechanism and the box body, the second motor drives the rod body to rotate. The rod body drives the roller to swing, and the roller drives the cross plate to move downward. The cross plate drives the vertical plate to move downward. When the roller is separated from the cross plate, the spring rebounds to drive the cross plate to move and then drive the vertical plate to move upward. The upper end of the vertical plate contacts the filter plate and then strikes and vibrates it. According to the above method, the vertical plate reciprocates to strike the filter plate, dredge the blocked filter plate, and thus improve the filtering speed of rice, thereby improving work efficiency.

[0028] Working principle:

[0029] When rice needs to be milled, connect the external power supply of the power devices of the two rice milling rollers 6 and start them to make the two rice milling rollers 6 rotate relative to each other (the power devices of the rice milling rollers 6 such as motors or others can be selected according to actual conditions to meet the working needs). Workers introduce the rice into the feed inlet 4 through external equipment. Subsequently, the introduced rice falls on the first plate body 205. Then, connect the external power supply of the first motor 202 and start it. The first motor 202 drives the gear 203 to rotate. The gear 203 drives the first rack 204 to move leftward, thereby driving the first plate body 205 to move. While the first plate body 205 moves leftward, the gear 203 will drive the second rack 206 to move, thereby driving the second plate body 207 to move rightward. After the first plate body 205 moves to the extreme position, the right end of the second plate body 207 will be clamped with the inner wall of the feed inlet 4. After the right end of the second plate body 207 is clamped with the inner wall of the feed inlet 4, turn off the first motor 202;

[0030] As the first plate body 205 moves, the rice on the first plate body 205 will be introduced onto the second plate body 207. After the rice on the second plate body 207 reaches the required amount, reverse the first motor 202. The second plate body 207 moves leftward and separates from the inner wall of the feed inlet 4. As the second plate body 207 moves, the rice on the second plate body 207 will fall onto the two rice milling rollers 6, while the first plate body 205 will be clamped with the inner wall of the feed inlet 4 again to block the rice. After the first plate body 205 is clamped with the feed inlet 4, turn off the first motor 202. Through the above method, the first plate body 205 introduces the rice above the feed inlet 4 onto the second plate body 207. After the rice on the second plate body 207 reaches the required amount, the second plate body 207 resets to introduce the rice on the second plate body 207 into the box body 1, and the first plate body 205 blocks the rice in the feed inlet 4, so that the rice enters the box body 1 quantitatively;

[0031] The outer walls of the two rice milling rollers 6 come into contact with the rice to perform shelling on the rice. The rice after shelling by the rice milling rollers 6 will fall on the filter plate 8. Impurities and rice husks larger than the mesh of the filter plate 8 will be blocked by the mesh in the filter plate 8 and remain on the mesh, while the rice will fall at the discharge port 5 and be discharged outside the box body 1, thereby filtering the rice. Workers use an external box for collecting rice to collect it, and perform rice milling work in the above way;

[0032] After the rice filtering is completed, connect the external power supply of the two vacuum cleaners 7 and start them. The vacuum cleaners 7 start to work. The vacuum cleaners 7 suck the rice husks and impurities that have fallen on the filter plate 8 into an external box for collecting rice husks for collection. After the impurities and rice husks are sucked out, turn off the two vacuum cleaners 7. Clean the rice husks and impurities on the filter plate 8 in the above way.

[0033] When the grid of the filter plate 8 is blocked, turn the bolt 9 to separate it from the filter plate 8. Then the worker removes it outside the box body 1 and turns it 180 degrees. After the filter plate 8 is turned, insert it reversely into the box body 1. After the filter plate 8 is turned and inserted into the box body 1 again, turn the two bolts 9 to make them abut against the filter plate 8, and then turn the filter plate 8 and fix it in the box body 1. Then connect the external power supply of the second motor 302 and start it. The second motor 302 drives the rod body 303 to rotate, the rod body 303 drives the roller 304 to swing, and the roller 304 drives the cross plate 305 to move downward (at this time, the spring 307 is stretched). The cross plate 305 drives the vertical plate 306 to move downward. When the roller 304 is separated from the cross plate 305, the spring 307 rebounds to drive the cross plate 305 to move and then drive the vertical plate 306 to move upward. The upper end of the vertical plate 306 contacts the filter plate 8 and strikes and vibrates it. According to the above method, the vertical plate 306 reciprocates to strike the filter plate 8. When the filter plate 8 vibrates, the impurities in the blocked grid will fall off, thereby dredging the filter plate 8 (since the end of the bolt 9 abuts against the filter plate 8 during work, the position of the filter plate 8 will not move during the striking and vibration of the filter plate 8). The dredged impurities will fall at the discharge port 5 and be discharged outside the box body 1. The worker can collect them with an external box for collecting impurities. After the filter plate 8 is dredged, fix the filter plate 8 in the box body 1 in the positive direction according to the above method. Dredge the blocked filter plate 8 in the above way. After the dredging is completed, draw out the filter plate 8, turn it over and insert it into the box body 1 to resume filtering use.
