Technical Field

The invention relates to the technical field of rice processing, in particular to a metering device for rice processing.

Background

Rice, also known as rice, is a food made from rice through the processes of cleaning, hulling, milling, finishing and the like. The rice is a main food for people in most areas in China, contains about 75 percent of carbohydrate, 7 to 8 percent of protein, 1.3 to 1.8 percent of fat and rich B vitamins and the like. The carbohydrate in the rice is mainly starch, the contained protein is mainly rice gluten, and the protein is secondly rice collagen and globulin, the biological value of the protein and the composition ratio of amino acid are higher than that of cereal crops such as wheat, barley, millet, corn and the like, the digestibility is 66.8-83.1%, the rice protein is also higher one of the cereal proteins, the last procedure of the rice processing is the packaging of the rice, and a metering device is adopted in the packaging process of the rice to avoid the situation that the weight of the packaged rice is higher or lower.

Patent publication number is CN106218931A discloses a metering device of grain processing, including bottom plate, cylinder one, cylinder two, cylinder three, control box, lower feed bin and controller, its characterized in that: the bottom plate is arranged on the support, the bearing frame, the limiting plate, the positioning plate and the weight sensing plate are arranged on the bottom plate, the limiting plate is provided with a limiting groove, and the first air cylinder and the second air cylinder are both arranged on the limiting plate.

The existing metering device for grain processing has the following defects:

when the existing metering device for grain processing is used, the weight sensing plate arranged on the bottom plate is used for detecting the weight, and when a specified numerical value is reached, the blanking valve is controlled to stop working, but the device is in a continuous blanking state during blanking, and the weight sensing plate can only detect the weight of rice which has been subjected to blanking and enters the container, so that when the weight sensing plate detects that the rice reaches a certain weight and stops working of the blanking valve, the rice which is discharged from the blanking valve but does not reach the container belongs to an excess part and also enters the container, and the accuracy of the device in use is reduced;

the metering device of current grain processing adopts the mode of centre gripping to carry on spacingly to the container, but the container that has been used for holding to put the rice adopts the structure that the flexibility is stronger more, and stability when using mechanical structure to carry out the centre gripping is general.
