[0002] The existing crushing and baling machine that processes field straw into feed includes a straw picker, a straw air conveying device, a straw crushing device, a dust removal device, a straw briquetting device and a baling device. Although the aforementioned baler can crush, briquette and pack the straw on the spot in the field more efficiently. However, it was found during use that there are still shortcomings that need to be improved. The more prominent common problem that the applicant has noticed is that the straw picked up by the straw picker in the existing mechanism crushing and baling machine is mostly transported to the crushing device or dust removal equipment through the air conveying device. Since our company has developed a machine that can crush the straw at the straw picker stage, the use of the existing air conveying device not only has the problem of a large overall baler equipment size, but also has problems such as high energy consumption and uncontrollable transportation process. There is an urgent need for a spiral dust removal and conveying system for straw crushing and baling machines that can effectively solve this problem. Utility Model Content
