Flow automatic control multifunctional coarse cereal rice mill

Abstract

The invention discloses a flow automatic control multifunctional coarse cereal rice mill which is applicable to half-polishing and whitening processing of various coarse cereals such as millets, proso millets, sorghums, myotonin, rice and the like. The flow automatic control multifunctional coarse cereal rice mill mainly consists of a feed hopper, a whitening chamber, a rack, a control box and a three-phase asynchronous motor; the feed hopper is fixed at the left upper part of the rack; the whitening chamber is arranged inside the rack; the control box is fixed at the right upper part of the rack; and the three-phase asynchronous motor is fixed on the ground. The feed hopper is provided with a flow automatic control device, so that the automatic control of the feeding speed is implemented; the whitening chamber can be matched with an emery roll or an iron roll for use; and the whitening chamber is also provided with a huller blade gap regulating device for regulating a gap between a huller blade and a roller. According to the invention, a control system which uses a PLC (Programmable Logic Controller) as the core is adopted; the flow automatic control multifunctional coarse cereal rice mill is suitable for milling the coarse cereals with various different shapes; the damage rate of materials is reduced; and the automation degree of equipment is improved.

Description

technical field [0001] The invention is a flow automatic control type multi-functional miscellaneous grain rice milling machine, in particular to a kind of grain machine equipment suitable for millet, large yellow rice, sorghum, job's tears rice, white rice and other miscellaneous grains. technical background [0002] The whitening room of the existing rice mill can only be installed with one of the emery roller and the iron roller, and cannot be compatible with the two, so it can only process certain specific miscellaneous grains. During the rice milling process, the gap between the rice knife and the roller cannot be adjusted, and the inlet gap and the outlet gap are consistent, resulting in the rice grains being easily broken and the rice milling quality not high. The biggest deficiency of the current rice milling machine is that the feeding speed is mainly adjusted manually, and when the current is too large, the feeding valve is manually closed. However, it is difficul...

AI Technical Summary

Problems solved by technology

[0002] The whitening room of the existing rice mill can only be installed with one of the sand roller and the iron roller, and cannot be compatible with the two, so it can only process a certain type of miscellaneous grains

During the rice milling process, the gap between the rice knife and the roller cannot be adjusted, and the inlet gap and the outlet gap are consistent, resulting in the rice grains being easily broken and the rice milling quality not high

The biggest shortcoming of the current rice milling machine is that the feeding speed is mainly adjusted manually. When the current is too large, the feeding valve is manually closed.

However, it is difficult to grasp the strength of manual adjustment. If the valve is closed too small, it will lead to insufficient feeding and the reduction of system current.

It is difficult to achieve the purpose of precise control by manually adjusting the flow rate, and at the same time, manual labor is required to perform repetitive work, resulting in low production efficiency
