Description

Technical Field

[0002] Rapeseed straw is the stalks left after the rapeseed seeds are harvested. Currently, rapeseed straw is processed through anaerobic fermentation. Anaerobic fermentation is also called anaerobic digestion. It refers to the process in which organic matter (such as human, livestock and poultry feces, straw, weeds, etc.) is decomposed and metabolized by various microorganisms under certain moisture, temperature and anaerobic conditions, and finally forms a combustible mixed gas such as methane and carbon dioxide. However, when fermenting rapeseed straw, users generally place the rapeseed straw directly in the fermentation device for fermentation, or crush it before fermentation and then put it into the fermentation device. The operation is relatively cumbersome. In addition, since the rapeseed straw is not crushed or crushed incompletely before fermentation, and the rapeseed straw is in a static piled state during fermentation, it is easy to lead to low fermentation efficiency.

[0003] After searching, a rape straw anaerobic fermentation treatment device disclosed in the prior art (Announcement No.: CN217709433U) records that "a crushing assembly is provided inside the crushing box; the crushing assembly includes an electric telescopic rod, the electric telescopic rod is arranged on the top of the crushing box, and a movable plate is fixedly provided at the output end of the electric telescopic rod, two fixed plates are provided at the bottom of the movable plate, and a clamping plate is provided on the opposite side of the two fixed plates, a first electric push rod is provided between the fixed plate and the clamping plate, an embedding groove is provided on the surface of the clamping plate, a first motor is provided inside the embedding groove, and a crushing knife is provided at the output end of the first motor"; the device is provided with a crushing assembly, and the electric telescopic rod drives the movable plate to move downward, so that the movable plate drives the fixed plate and the clamping plate to move, and the first electric push rod is used to respectively The corresponding clamping plates are driven to move relative to each other, thereby relatively pushing the rape straw on the surface of the placement plate, and the crushing knife is driven to rotate by the first motor to crush the rape straw between the two clamping plates, thereby improving the fermentation efficiency of the rape straw. However, when the device is actually crushing the rape straw, workers need to adjust the position of the placed rape straw accordingly, which makes the processing efficiency of the rape straw low, and if the cutting direction of the rape straw and the crushing knife are parallel, the crushing effect of the device on the rape straw will be seriously reduced, which will affect the subsequent fermentation efficiency. At the same time, after the device completes the crushing of the rape straw, it lacks a corresponding filtering and screening structure, so that both rape straw fragments of qualified size and rape straw fragments of unqualified size will be sent into the fermentation box, thereby reducing the fermentation efficiency inside the fermentation box.
