Description

Straw collecting briquetting machine Technical Field The application relates to the field of intelligent agricultural power machine manufacturing, in particular to a straw collecting briquetting machine. Background In the field of agricultural straw treatment, a straw collecting briquetting machine is core equipment for realizing straw recycling, and loose straws are processed into high-density blocky materials through procedures such as picking up, conveying, briquetting and the like, so that the straw collecting briquetting machine is convenient to store and transport. In the conveying mechanism of the existing straw collecting briquetting machine, a feeding fork is used as a key component for conveying straws, and a fixed length or single motion track design is adopted, so that the single function of continuous conveying can be realized, and the conveying quantity can not be flexibly adjusted according to the processing rhythm of the straw briquetting mechanism. In the actual operation process, because the pickup amount of the straw has fluctuation (such as uneven density of the straw in the field and fixed rotating speed of the pickup device), when the pickup amount is larger than the instant processing amount of the briquetting mechanism, the fixed-motion feeding fork still can continuously convey the straw to the feeding hole area, so that the straw is continuously piled up at the joint of the feeding hole and the conveying mechanism. Meanwhile, the irregular distribution of the stacked straws can cause uneven raw material supply in the subsequent briquetting process, thereby affecting the density consistency of briquetted products and reducing the overall operation efficiency. At present, aiming at the problem of straw accumulation at a feed inlet which is easy to cause by the existing feeding fork mode, no effective solution capable of realizing dynamic adjustment and self-adaptive matching of the briquetting rhythm is proposed in the industry.
