The invention relates to the field of rice processing, in particular to an automatic rice processing production line.

Background

Rice (Rice) is a finished product made from Rice through the processes of cleaning, hulling, milling and finishing, and is a main food for people in most areas of China. The rice contains nearly 64 percent of nutrient substances in the rice and more than 90 percent of nutrient elements required by human bodies, and the rice contains about 75 percent of carbohydrate, 7 to 8 percent of protein, 1.3 to 1.8 percent of fat, abundant B vitamins and the like. The existing rice processing production line mainly comprises equipment such as a ridge rice machine, a rice-husked separator, a rice mill, a polishing machine, a color sorter and the like, and the equipment is transported among the processing equipment by pipelines. However, in the current rice processing process, when a certain device fails, the device of the previous processing procedure is still in operation, and the device needs to be stopped emergently to avoid the accumulation or overflow of the rice processed in the previous processing procedure in the pipeline. At present, after a field worker observes an equipment fault, the equipment is manually closed, the problem of rice accumulation or overflow caused by untimely treatment often occurs in the operation method, and the cleaning cost in the later period is increased.

Disclosure of Invention

The invention aims to provide an automatic rice processing production line to solve the problems that rice is easy to stack or overflow and cleaning cost is increased due to equipment failure in the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: automatic change rice processing lines, include the frame and install the rice processing equipment in the frame in proper order, install transmission pipeline between the adjacent processing equipment, transmission pipeline slope sets up, and the feed end of transmission pipeline and the discharge gate flexonics of preceding processing equipment, the discharge end of transmission pipeline and the feed inlet intercommunication of back processing equipment, the storehouse of keeping in is installed to the below of processing equipment, be provided with on the storehouse of keeping in can with the mouth of keeping in of transmission pipeline intercommunication, install the adjustment mechanism who is used for adjusting transmission pipeline height in the frame, adjustment mechanism adjusts the high position of transmission pipeline according to the gravity of transmission pipeline.
