Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice mill with a quick-disassembly structure. Background Art

[0002] Rice is the finished product of rice after harvesting, cleaning and milling. Rice needs a professional rice milling machine to transform into rice grains. The working principle of the rice milling machine is to squeeze and grind the rice grains to separate the rice ears and rice grains.

[0003] When processing products, especially large industrial machines, they need to be disassembled and installed during transportation. The parts are relatively complex. Direct transportation is time-consuming and laborious. Therefore, a quick-release assembly that can quickly disassemble and install agricultural tools is needed to greatly save manpower and material resources.

[0004] The existing patent (publication number: CN204865932U) discloses a rice milling machine, including a casing, a feed hopper, a rice roller and a rice sieve, the casing having a cylindrical rice milling chamber, the rice milling chamber being communicated with the feed hopper, and the feed hopper being located at one cylindrical end of the rice milling chamber, the other end of the rice milling chamber having a rice outlet, the rice roller being coaxially arranged in the rice milling chamber, the surface of the rice roller being provided with feeding spiral ribs and rice milling spiral ribs, a section where the feeding spiral ribs are located corresponding to the feeding hopper, the rice sieve being cylindrical, the rice sieve being coaxially sleeved on the rice roller corresponding to a section where the rice milling spiral ribs are provided, the spiral direction of the rice milling spiral ribs is opposite to that of the feeding spiral ribs, and the spiral angle of the rice milling spiral ribs is greater than twice the spiral angle of the feeding spiral ribs. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The rice milling machine is a large-scale equipment commonly used in agriculture. When it is needed in every harvest season, it is troublesome to disassemble, install and transport it; 2. After the rice roller in the rice milling machine separates the rice ears from the rice, it is necessary to use pressure and rotation stirring to screen the rice ears with smaller diameters out of the machine. However, the machine keeps rotating, and a large number of rice ears accumulate on the screen, which will clog the inside of the screen, thereby increasing the processing time. After the processing is completed, the rice and part of the rice ears cannot be separated, which increases the subsequent processes for users. Utility Model Content

Then the transmission belt is put on the transmission wheel 13 and the right end of the rice milling roller 8. After checking that the installation is firm, start the double-axis motor 4;

[0035] The dual-axis motor 4 drives the connecting shaft 12 and the rotating roller 5 to rotate, and the user can pour the rice into the hopper 3. The rotating roller 5 rotates to transfer the rice into the rice milling frame 6 in batches, and the connecting shaft 12 drives the transmission wheel 13 to rotate, and drives the rice milling roller 8 to rotate through the transmission belt to grind the rice inside the rice milling frame 6. Due to the special threaded structure of the outer ring of the rice milling roller 8, the rice is continuously transported to the right and ground. Then the ground rice ears and rice grains fall out along the right end of the rice milling frame 6 and fall onto the top of the rice screening plate 7. The rotation of the rice milling roller 8 drives the striking leather strip 9 to rotate, and intermittently strikes the right end of the rice screening plate 7, so that the rice ears that fall onto the top of the rice screening plate 7 can continue to shake and fall to the bottom of the outer frame 1 of the rice milling machine.
