Description

Realize vacuum material loading machine of accurate feed Technical Field The invention relates to the technical field of farm product transportation equipment, in particular to a vacuum feeding machine capable of achieving accurate feeding. Background The vacuum feeder is used as a device for conveying powdery and granular materials by utilizing vacuum negative pressure, and has wide application in the fields of agricultural product processing, food, chemical industry and the like. However, in the prior art, conventional vacuum feeders have revealed significant drawbacks, especially when handling materials such as agricultural products that are not fluid and are prone to stacking or bridging. At present, a fixed-length suction hose is generally adopted, and the position of a suction head of the suction hose is relatively fixed. In actual operation, as the material in the material cylinder or the material pile is continuously sucked away, the material level continuously descends, so that the distance between the suction head and the surface of the material is gradually increased. Once the suction head is separated from the surface of the material or is not tightly attached, a large amount of air can be sucked, the effective vacuum degree of the system is seriously reduced, the suction efficiency is drastically reduced, and even the feeding is completely interrupted. To solve this problem, operators have to frequently perform manual interventions, such as manually pressing down or adjusting the hose position, in an attempt to bring the suction head back into contact with the material. The manual assistance not only greatly increases the labor intensity of operators and reduces the automation level of equipment, but also causes unstable and inaccurate feeding process due to incapability of realizing accurate and continuous following, thereby seriously affecting the continuity and the product quality of the subsequent production process. In addition, agricultural product materials such as beans, powder, crushed aggregates and the like are easy to generate bridging or blocking phenomena at the inlet of the suction head due to negative pressure and material characteristics, so that smooth suction of the materials is further hindered, and the requirement of manual intervention is more frequent.
