Description

Technical Field

[0001] The utility model relates to the technical field of emery rollers, in particular to an anti-clogging rice milling emery roller. Background Art

[0002] my country has widely adopted mechanical method to whiten brown rice. It uses special equipment (rice mill) to drive the rice milling sand roller to rotate, and uses the pressure between rice grains and the effect of sand roller and fan to make the rice grains rub against the sand roller and screen plate to achieve the effect of removing rice skin. The grinding force mainly comes from the high-speed rotation between the inner roller and the outer cylinder and the sand blades of the diamond grains on the surface. Brown rice is continuously ground as an interlayer in the chaotic movement, causing its skin to crack and fall off, and the brown rice is whitened. The pressure required to remove the rice skin by this method is relatively small, and less broken rice is produced.

[0003] The existing rice milling sand rollers are usually equipped with a spiral rice milling trough. The rice bran formed when the rice skin is crushed in the spiral rice milling trough is easy to adhere to the inner wall of the rice milling trough and gradually accumulate, which will eventually cause the rice milling trough to be blocked, resulting in incomplete rice milling. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an anti-clogging rice milling sand roller in view of the above shortcomings.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A clogging-proof rice milling sand roller comprises an iron core and a rice milling drum, wherein a hollow cylindrical shape is arranged on the outer side of the iron core, and an iron core is fixed on the inner side of the rice milling drum, wherein the iron core comprises an outer ring and an inner ring, a cavity is formed between the outer ring and the inner ring and the outer ring is connected by a connecting column, the outer ring is used for being installed in cooperation with the internal cavity of the rice milling drum, and the inner ring is used for being installed in cooperation with the rotating shaft; a plurality of spiral rice milling grooves are provided on the outer surface of the rice milling drum, a plurality of groups of ventilation holes are provided on the inner side of the spiral rice milling grooves, and each group of ventilation holes is connected with the internal cavity of the rice milling drum.

[0007] Furthermore, each group of ventilation holes includes 4-20 ventilation holes, and a plurality of ventilation holes are arranged side by side along the lower trough edge of the spiral rice milling trough.

[0008] Furthermore, the diameter of the ventilation hole is 8-30 mm.

[0009] Furthermore, an annular groove for reducing the contact area is provided on the inner side of the inner ring.

[0010] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0011] The utility model provides ventilation holes and an internal cavity, so that the flowing air blown by the fan on the rice milling machine flows in the internal cavity and then blows out from the second ventilation hole, so as to blow away the rice bran formed on the surface of the rice grains in time, and avoid the spiral rice milling groove being blocked by excessive rice bran attached to the inner side of the spiral rice milling groove, thereby ensuring sufficient rice milling; by providing an annular groove on the inner side of the shaft hole of the iron core, the contact area between the shaft hole and the main shaft of the machine tool is reduced, and the friction resistance of the sand roller blank to the main shaft of the machine tool during installation is smaller, so that the installation of the sand roller blank is easier.
