Description

Technical Field

[0001] This utility model relates to the field of rice milling machine technology, specifically to a multi-channel rice milling machine for removing chaff. Background Technology

[0002] A rice milling machine is a machine that removes the outer husk of grains, also known as bran. It separates the bran from the grain, and the grain and bran are output from two separate outlets. Traditional rice milling machines are not very efficient at removing bran, which affects the collection of grains. For example, when collecting grains, some bran is mixed in, or some rice is mixed in when collecting bran, which affects the efficiency of collecting rice.

[0003] Existing rice milling machines have low bran removal efficiency, affecting rice output efficiency. For example, Chinese Patent Publication No. CN210022234U discloses a rice milling machine with secondary bran removal function, which includes an upper feeding device, a machine casing, a frame, a drive device, a main shaft, a bran screening device, and a rice milling sand roller. The main shaft is installed in the middle of the bran screening device, and a spiral propeller is set on its upper part. A whitening chamber is formed between the rice milling sand roller and the bran screening device, which connects to the bran collection chamber and the rice collection chamber. The left side of the bran collection chamber is a first bran suction pipe, and the lower part is the frame. The left side of the frame is equipped with a secondary bran removal chamber, whose left and right sides are screen plates. The outside of the left side wall is equipped with a second bran suction pipe and connected to the first bran suction pipe. Its bottom surface is a guide grid. Below the rice collection chamber is the rice outlet, which leads to the secondary bran removal chamber. A material accelerator is set at the rice outlet to scatter the rice at high speed, so that the bran powder is drawn out by the negative pressure fan. The rice falls onto the guide grid, where the small amount of bran powder mixed in is sucked away again. The two discharges in this scheme require the use of dual-drive dry mechanisms, which consume a lot of energy. In addition, the two chaff removal processes, which involve scattering, result in a lot of dust in the workshop, affecting the workers' working environment. Utility Model Content

[0004] The purpose of this invention is to provide a multi-channel rice milling machine for removing chaff, so as to solve the problem of low chaff removal efficiency in rice milling machines in the present technology.

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

[0006] A multi-channel rice milling machine for removing chaff includes a feeding port, a feeding bin, and a rice milling mechanism. The top of the feeding port is connected to a feeding channel, and the bottom of the feeding port is equipped with a feeding bin. The bottom of the feeding bin is connected to the rice milling mechanism. A power supply mechanism is provided on the side of the rice milling mechanism. A blower and a fixed roller are electrically connected in the power supply mechanism. A movable roller is provided near the fixed roller. The end of the movable roller is pushed by a cylinder. A buckle is also installed on the cylinder's push shaft. The buckle is sleeved on one side of the movable roller's shaft end. The bottom of the buckle extends into the rice milling channel and connects to the milling roller. The milling roller contacts the screen.

[0007] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0008] This invention uses two rice-milling rollers, one rotating and one stationary. A cylinder drives the rotating roller to move back and forth, initially crushing the grain. The grain is then further crushed by the reciprocating motion of the rotating roller, thus improving crushing efficiency. The rice-milling mechanism has bottom and side outlets to distribute the crushed grain through multiple outlets. These multiple channels increase the contact area with the grain, improving chaff removal efficiency. The specially shaped rice-milling channels provide space for secondary crushing and facilitate grain transport. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figures 1-3The multi-channel rice milling machine for removing chaff shown includes a feeding port 1, a feeding bin 3, and a rice milling mechanism 4. The top of the feeding port 1 is connected to the feeding channel 2, and the feeding bin 3 is installed at the bottom of the feeding port 1. The bottom of the feeding bin 3 is connected to the rice milling mechanism 4. A power supply mechanism 5 is provided on the side of the rice milling mechanism 4. A blower 403 and a fixed roller are electrically connected inside the power supply mechanism 5. A movable roller 6 is provided near the fixed roller. The end of the movable roller 6 is pushed by a cylinder 10. A buckle 7 is also installed on the push shaft 10. The buckle 7 is sleeved on one side of the shaft end of the movable roller 6. The bottom of the buckle 7 extends into the rice milling channel 11 and connects with the milling roller 9. The milling roller 9 contacts the screen 12. The screen 12 is fixedly connected to the opening of the rice milling channel 11, and a discharge plate 13 is also fixedly connected to its opening. A discharge plate 2 14 is connected to the bottom of the rice milling channel 11. The discharge plate 2 14 and the discharge plate 13 have the same inclination angle, and the rice milling channel 11 is S-shaped.

[0018] The entire rice milling mechanism 4 crushes the outer shell of the grain for the first time between two rollers. The uncrushed grain is then transported to the rice milling channel 11 and crushed a second time, which improves the efficiency of rice milling. A rotating iron rod or sand roller increases the resistance of rice milling. The non-rotating roller can be controlled by the cylinder 10 to improve the efficiency of rice milling.

[0019] The milling roller 9 is composed of multiple horizontally arranged rotating shafts, and the milling roller 9 is rotatably connected to the bottom of the rectangular push rod 8. The top of the rice milling mechanism 4 has a feeding port 401, and the bottom and one side of the rice milling mechanism 4 have a discharge port 402. Multiple blowers 403 are installed inside the rice milling mechanism 4. The back of the rice milling mechanism 4 has a bran outlet. The multiple blowers 403 correspond to multiple turning points of the rice milling channel 11, and also correspond to the middle of the discharge plate 13 and the discharge plate 2 14. The discharge plate 2 14 corresponds to the discharge port 402 at the bottom of the rice milling mechanism 4, and the discharge plate 13 corresponds to the discharge port 402 on the side of the rice milling mechanism 4. The screen 12 is a metal mesh and is fixedly installed on the transverse plate of the rice milling channel 11. The longitudinal plate at the top of the rice milling channel 11 divides the grain into two parts, and an opening is opened near the top longitudinal plate of the rice milling channel 11.

[0020] The cylinder 10 controls the back-and-forth movement of the movable roller 6, which drives the movement of the buckle 7 and the push rod 8, causing the milling roller 9 to roll back and forth on the screen 12, crushing the grain a second time. After that, the grain is conveyed to different discharge ports 402. The special shape of the rice milling channel 11 can also buffer the grain well and leave a large space for crushing.

[0021] Working principle of this utility model:

[0022] Refer to the instruction manual appendix Figures 1-3 During operation, the grain is first transported to the positions of each feeding port 1 through the feeding channel 2, and then received by multiple parallel feeding ports 1 before being transported into the rice milling mechanism 4.

[0023] During the process of being conveyed to the rice milling mechanism 4, the grain passes through a rotating roller and a non-rotating roller, namely the movable roller 6. The outer shell of the grain is crushed as it passes between the two rollers. The movable roller 6 is continuously pushed back and forth by the cylinder 10 to improve the efficiency of rice milling.

[0024] Refer to the instruction manual appendix Figures 3-5 The cylinder 10 pushes the buckle 7 and the movable roller 6 back and forth, causing the push rod 8 and the grinding roller 9 to move back and forth on the screen 12. The grain whose outer shell has been crushed by the two rollers is crushed again on the screen 12, reducing the amount of uncrushed grain.

[0025] The grain that has been crushed twice falls down from the screen 12 and is conveyed to the discharge plate 13 and discharge plate 2 14 respectively. During the conveying process, the outer shell is blown out of the rice milling mechanism 4 by multiple blowers 403. The rice with the crushed outer shell is conveyed out from the discharge plate 13 and discharge plate 2 14.

[0026] 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.
