Abstract

The invention relates to the field of agricultural machinery, in particular to a double-shaft straw cutting and returning machine which can effectively achieve cutting and returning treatment on cornstraw and can cut up a whole plant and cut the whole plant into sections. The double-shaft straw cutting and returning machine comprises a machine frame, the machine frame is provided with a front main shaft and a rear main shaft which are parallel to each other, the front main shaft is provided with a rough cutting device in the circumferential direction, the rear main shaft is provided with a fine cutting device in the circumferential direction, and the rotation direction of the front main shaft is opposite to that of the rear main shaft. The front main shaft is provided with the rough cutting device used for chopping whole or long straw, the rear main shaft is provided with the fine cutting device used for cutting the straw into sections, the front main shaft and the rear main shaft rotate in the opposite directions, the rough cutting device can throw the cut straw sections backwards, and the fine cutting device can cut the straw into the sections more easily.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a biaxial straw cutting segment returning machine. Background technique [0002] Returning corn stalks to the field is the main utilization method of corn stalks in my country, and the quality of corn stalks chopping directly affects the sowing quality and yield of off-season crops. More thorough chopping of the corn stover will aid subsequent sowing. In order to meet the requirements of sowing, the rotation speed of the corn stalk returning machine is usually increased. However, due to the limitation of the chopping principle, the chopped corn stalks are still in the form of filaments, which are connected by fibers, which cannot solve the problem of cutting straws. In recent years, some domestic manufacturers have proposed biaxial shredding of corn stalks, but the working parts of biaxial shredding are still hammer claws or swinging knives, which still cannot solve the pro...
