Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a straw crushing device for agricultural machinery. Background Art

[0002] Straw is the main by-product of crops and an important biological resource for industry and agriculture. Crop straw contains rich nutrients and can be used as fertilizer, feed, domestic fuel and raw material for industrial production, etc., referred to as "four materials".

[0003] The patent document with the prior art publication number CN115529949A provides an agricultural machinery straw crushing device, including a crushing box, a left side surface of the crushing box is connected to a feed bin, a plurality of cutting blades are evenly arranged on the outer ring wall of a rotating ring, and the rotating ring is fixedly connected to the end of a rotating shaft, and the plurality of cutting blades are rotatably arranged at the connection between the feed bin and the crushing box, the rotating shaft is rotatably supported on the top wall of the crushing box by a plurality of support rods, and the other end of the rotating shaft passes through the right side wall of the crushing box and is connected to the output shaft of a motor fixed on the crushing box, symmetrical crushing rollers are rotatably arranged inside the crushing box through the rotating shaft, elastic guide plates are arranged above the crushing rollers, elastic screens are arranged below the symmetrical crushing rollers, and the two ends of the elastic screens are respectively connected to the left and right side walls of the crushing box; the present invention can not only prevent the clogging of long green storage straw during direct crushing, but also improve the crushing quality and crushing efficiency of long green storage straw.

[0004] However, during the use of the existing agricultural machinery straw crushing device, since the straw itself contains moisture and is relatively soft, when the crushing device is crushing, part of the straw will follow the crushing knife to rotate, while part of the straw will not be crushed completely. Since the crushing device cannot collect the straw that is not completely crushed for secondary crushing during the crushing process, the straw crushing effect is poor. For this reason, we propose an agricultural machinery straw crushing device. Utility Model Content
