Background
China has a large population and a large grain demand. Grain reserves are fundamental guarantees of survival and development of people, and they are related to national security and social stability. Grain surface leveling is the last procedure of grain storage. Among them, standardization management and the application of new technology play an important role in grain storage, wherein the structural characteristics and performance of grain machinery play a vital role in leveling grain surfaces. At present, few machine equipment for leveling grain surfaces at home and abroad are mainly divided into a fixed grain leveling machine and a movable grain leveling machine.
The fixed grain leveling machine is usually fixed at the top of the granary to perform grain leveling work, so that non-grain leveling parts cannot be contacted with grains, the working area is wide, and grain leveling is easy to perform. Because the working steps of the fixed grain flattening machine generally firstly flatten the whole high-protruding grain surface of grains into the low-protruding grain surface, and then flatten the grain surface from the low-protruding grain surface into a plane, but only single working parts are arranged, when the grain surface faces the high-protruding grain surface, grains are contacted less, but all the work is designed according to the low-protruding grain surface, so that the grain flattening efficiency is not high, the grains are contacted continuously when the parts are singly operated, abrasion is easy to cause, failure is generated, dust is possibly caused at high speed, and the grain flattening machine is structurally limited to be very time-consuming and low in precision when the grain flattening machine is used for large grain bins.
The movable grain flattening machine is generally driven by a crawler belt as a chassis, and the upper machine body performs grain flattening. The advantage is that the work is more free, can pass in and out the granary wantonly. The drawbacks are also evident in that it is required to be able to move, resulting in complex structures, high costs and poor stability, and in the case of complex relief of the grain surface, the efficiency of the flat grain is low, and the flat grain components are generally limited to the type of concave push plate and screw shaft.
