Description
Technical Field

[0002] The processing of paddy rice refers to the process of removing the husk (glume) and cortex (bran layer) of paddy rice and finally producing rice with good edible quality. A paddy rice grain consists of a husk, cortex, embryo, and endosperm. The purpose of paddy rice processing is to separate the endosperm from other parts with the least degree of breakage and produce rice with good edible quality. With the development of the times, the development of industry and agriculture has become increasingly modernized. Since the production of paddy rice accounts for a relatively large proportion in agricultural production, the required paddy rice production and processing equipment is also increasing day by day. During the process of paddy rice production and processing, it is usually necessary to remove its husk, and at this time, a rice hulling and milling device for paddy rice is needed.

[0006] The present invention has the following beneficial effects: 1. In the present invention, the rice to be husked and milled is poured onto the rotating paddle by the cooperation of the main box frame, the rice feeding mechanism, the driving mechanism, the rice milling and husking mechanism and the strip through groove. The paddle rotates to quantitatively distinguish the rice to be husked and milled, so that the rice to be husked and milled falls onto the bucket at a constant speed, passes through the rice inlet at a constant speed under the paddle movement, and falls onto the screw pressure roller. After the rice to be husked and milled falls onto the screw pressure roller, it falls under the screw pressure roller as the screw pressure roller rotates, and is squeezed by the screw pressure roller and the inner bottom of the main box frame, thereby achieving the function of rice milling and husking. The husking mechanism rotates and the rice-pulling bars flip and flick the rice grains that are stuck to the husks, so that the rice and the husks in the rice grains are separated, and various impurities such as rice stalks or weed seeds mixed in the rice during the harvesting process are flicked out. At the same time, the thumb wheel flips to turn over the rice that needs to be husked and milled to prevent the accumulation of rice that needs to be husked and milled. When the rice husking effect meets the standard, the rice falls through the bar-shaped through groove, thereby turning and flicking the rice poured in the husking and rice milling process, which is more conducive to husking and rice milling, and can also prevent the equipment from accumulating and clogging during the husking and rice milling process, resulting in equipment failure and inability to work normally.
[0007] 2. In the present invention, through the mutual cooperation of the linkage mechanism, the bottom box, the notch, the through port, the rice screening mechanism and the guiding hopper, the rice falling through the strip-shaped through groove falls into the outer shell through the rice inlet under the guidance of the guiding hopper and lands on the sieve plate. During the falling process, it is blown by the wind blown out from the air outlet, and a certain amount of shells and broken weeds mixed in the falling rice are blown out of the equipment through the lower shell outlet, cleaning the shelled rice. Then, the rice landing on the sieve plate can be cleaned again during the vibration sieving process, and the two sieve plates can perform double sieving, making the cleaning effect better. The shelled rice that meets the standard falls through the sieve plate, slides along the inner wall of the lower side of the outer shell to the rice outlet pipe, and finally slides out along the rice outlet pipe, facilitating collection for subsequent use. The screened impurities remain on the sieve plate and are blown away by the wind blown out from the air outlet, and then are blown away from the equipment along the lower shell outlet. Thus, the shelled and milled paddy is screened, and various impurities such as rice straws or weed seeds mixed in the paddy during the harvesting process are cleaned to a certain extent, improving the quality of rice, ensuring production safety, and preventing harm to human health.

A pulley two 34 is fixedly connected to the side of the pulley three 33 far from the rotating shaft 32. A pulley four 35 is fixedly connected to the end of the main rod 81 close to the pulley one 26. The outer walls of the pulley three 33 and the pulley four 35 are connected by a synchronous belt one 36, and the outer walls of the pulley one 26 and the pulley two 34 are connected by a synchronous belt two 37. Before using this equipment, place this equipment at the required position, start the motor 31, drive the rotating shaft 32 to rotate, drive the pulley three 33 and the pulley two 34 to rotate, and then drive the pulley one 26 to rotate through the synchronous belt two 37, thereby driving the rotating rod 24 and the dial plate 25 to rotate. At the same time, drive the pulley four 35 to rotate through the synchronous belt one 36, thereby driving the rice hulling and milling mechanism 8 to rotate. At the same time, the rotating shaft 32 drives the connecting rod 47 to rotate through the bevel gear one 38 and the bevel gear four 49, and then drives the shaft rod 42 to rotate through the bevel gear three 48 and the bevel gear two 45. Finally, drive the runner 916 and the main shaft 913 to rotate together through the pulley five 43 and the synchronous belt three 44. The main shaft 913 drives the fixed block 914 and the strip-shaped fan blade 915 to rotate together. The fixed block 914 and the strip-shaped fan blade 915 rotate inside the loading shell 912, and then blow out air through the air outlet 9111. When the runner 916 rotates, it drives the linkage rod 918 through the positioning block 917, so that the linkage rod 918 pulls the fixed frame 919 to reciprocate along the sliding groove 9113, thereby driving the sieve plate 9110 to slide reciprocally inside the outer shell 911 through the fixed frame 919, so as to play a role of vibrating and sieving.

The rice falling through the strip-shaped through slot 11 is guided by the guiding hopper 10 and falls into the outer shell 911 through the inlet for rice 9112 and lands on the sieve plates 9110. During the falling process, it is blown by the wind blown out from the air outlet 9111, and a certain amount of shells and broken weeds mixed in the falling rice are blown out of the equipment through the lower outlet 92 to clean the shelled rice. After that, the rice landing on the sieve plates 9110 can be cleaned again during the vibration sieving process, and the two sieve plates 9110 can perform double sieving, making the cleaning effect better. The shelled rice that meets the standard falls through the sieve plates 9110, slides along the inner wall of the lower side of the outer shell 911 to the rice outlet pipe 93, and finally slides out along the rice outlet pipe 93 for convenient collection and subsequent use. The screened impurities remain on the sieve plates 9110 and are blown away by the wind blown out from the air outlet 9111, and then are blown away from the equipment along the lower outlet 92, thereby screening the shelled and milled paddy rice.
[0013] Working principle: before using the device, place the device in the required position, start the motor 31, drive the rotating shaft 32 to rotate, drive the pulley three 33 and the pulley two 34 to rotate, and then drive the pulley one 26 to rotate through the synchronous belt two 37, thereby driving the rotating rod 24 and the dial plate 25 to rotate, and at the same time drive the pulley four 35 to rotate through the synchronous belt one 36, thereby driving the rice milling and shelling mechanism 8 to rotate, and at the same time the rotating shaft 32 drives the connecting rod 47 to rotate through the bevel gear one 38 and the bevel gear four 49, and then drives the shaft rod 42 to rotate through the bevel gear three 48 and the bevel gear two 45, and finally drives the rotating wheel 916 and the main shaft 913 to rotate together through the pulley five 43 and the synchronous belt three 44, and the main shaft 913 drives the fixed block 914 and the strip fan piece 915 to rotate together, and the fixed block 914 and the strip fan piece 9 15 rotates inside the loading shell 912, and then blows out air through the air outlet 9111. When the rotating wheel 916 rotates, it drives the linkage rod 918 through the positioning block 917, so that the linkage rod 918 pulls the fixed frame 919 to reciprocate along the slide groove 9113, thereby driving the screen plate 9110 to slide back and forth inside the shell 911 through the fixed frame 919, thereby playing a role of vibration screening, and the rice to be shelled and milled is poured onto the rotating paddle 25. The paddle 25 rotates to quantitatively distinguish the rice to be shelled and milled, so that the rice to be shelled and milled falls on the bucket 22 at a constant speed, and passes through the rice inlet 28 at a constant speed under the paddle 25, and falls on the screw pressure roller 82. The semi-annular plate 27 can prevent the rice to be shelled and milled from being dumped during the flipping of the paddle 25. The rice is pushed out of the bucket 22, and the rice to be husked and milled falls on the screw pressure roller 82. As the screw pressure roller 82 rotates, it falls under the screw pressure roller 82, and is squeezed by the screw pressure roller 82 and the inner bottom of the main box frame 1, so as to achieve the effect of rice milling and husking. The rice after milling, the rice with relatively ideal husking, falls through the sieve of the strip through groove 11. After milling, some rice and husks in the rice may be adhered to each other and cannot pass through the strip through groove 11. As the screw pressure roller 82 rotates, the rice follows the screw path on the screw pressure roller 82 to reach the range of the rice-pulling bar 83. As the rice milling and husking mechanism 8 rotates, the rice-pulling bar 83 turns over and pulls the rice with the husks adhered to each other, so that the rice and husks in the rice are separated, and the rice stalks or weeds mixed in the rice during the harvesting process are pulled out. The rice that needs to be husked and milled is turned over by the dial wheel 85 to prevent the accumulation of the rice that needs to be husked and milled. When the husking effect of the rice is up to standard, the rice falls through the strip through groove 11, thereby turning and dialing the rice poured in the husking and rice milling process, which is more conducive to husking and rice milling, and can also prevent the equipment from accumulating and clogging rice during the husking and rice milling process, resulting in equipment failure and malfunction. The rice that falls through the strip through groove 11 falls into the outer shell 911 through the rice inlet 9112 under the guidance of the guide bucket 10 and falls on the sieve plate 9110. During the falling process, it is blown by the wind blown out from the air outlet 9111, and a certain amount of husks and broken weeds mixed in the fallen rice are blown out of the equipment through the lower shell outlet 92, so that the husked rice is cleaned.The rice that subsequently falls on the sieve plate 9110 can clean the husked rice again during the vibrating sieving process, and the two sieve plates 9110 can perform double sieving, resulting in a better cleaning effect. The husked rice that meets the standard falls through the sieve plate 9110 and slides along the inner wall of the lower side of the outer shell 911 to the rice outlet pipe 93, and finally slides out along the rice outlet pipe 93 for easy collection and subsequent use. The sieved impurities remain on the sieve plate 9110 and are blown away by the wind blown out from the air outlet 9111, and then are blown away from this device along the lower husk outlet 92. Thus, the paddy after hulling and milling is screened, and various impurities such as rice straws or weed seeds mixed in the paddy during the harvesting process are cleaned to a certain extent, improving the quality of rice, ensuring production safety, and preventing damage to human health.
