A control method and device for feeding and discharging materials in a rice milling chamber

Abstract

The invention discloses a control method and device for rice milling chamber feeding and discharging. The control method includes the steps of (a) early-stage preparation, (b) traction rod position adjustment, (c) rice milling chamber feeding and discharging pre-commissioning, (d) rice milling chamber allocation adjustment, (e) rice milling chamber feeding and discharging regulation and control, and (f) hydraulic device working pressure adjustment. The device comprises a rice milling chamber and control mechanisms. A rice feeding movement valve is arranged at one end of the rice milling chamber, and a rice discharging movement valve is arranged at the other end of the rice milling chamber. Each control mechanism comprises a workbench, a hydraulic device and a traction mechanism. Each hydraulic device is provided with a pushing rod. Each traction mechanism comprises a traction base and a traction rod. The pushing rods are connected with the corresponding traction bases. By means of the control method and device, a feeding inlet meeting the size requirement of rice species and a discharging outlet meeting the size requirement of the rice species are started according to the categories of specific rice species, so that the sizes of the inlet and the outlet are effectively controlled, time and labor are saved, rice losses are reduced, and the head rice rate is increased. The control effect of the device is good, moreover, the control process can be completed only through two persons, and cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of feeding and discharging materials in a rice milling chamber, and in particular relates to a control method and device for feeding and discharging materials in a rice milling chamber. Background technique [0002] Rice is the main resource that our human beings depend on for survival. The endosperm of the grain accounts for about 70%-75% of the whole grain, while the processing rate of "polished rice and flour" is only about 60%. The rollers are lengthened, thickened, and passed through multiple passes, resulting in a huge waste of food resources and the loss of nutrients in the grain cortex. The whole rice milling process has low rice polishing rate, high energy consumption and large loss, so it is difficult to add value in processing. [0003] In view of the problems of low rice milling rate, high energy consumption and large loss in the rice milling process, higher technical requirements are put forwar...

Problems solved by technology

[0004] At present, in the process of rice feeding and rice output in the rice milling room, most of the B-type machines are used. The feeding of this machine is not controlled, and the discharging is controlled by orifice plates with different diameters. Different types of rice need to replace orifice plates with different apertures to control the processing quality. , resulting in cumbersome and time-consuming replacement of various orifice plates, unable to control the feeding and discharging of the rice milling room, and the precision of rice is not easy to control
