The invention discloses a straw returning device which comprises an outer cover, a drive structure, a rotary rod and a plurality of smashing cutters. The drive structure is mounted on the outer cover and comprises a hydraulic motor. The rotary rod is rotatably mounted in the outer cover. The smashing cutters sleeve the outer periphery of the rotary rod. The hydraulic motor can drive the rotary rod to rotate. The smashing cutters can rotate along with the rotary rod to smash straw. The straw returning device has the advantages that the smashing cutters sleeve the rotary rod, the smashing cutters can rotate along with the rotary rod driven to rotate by the hydraulic motor so as to smash the straw; in addition, the straw returning device is simple in structure, the rotation directions of the rotary rod can be adjusted easily due to the fact that the rotary rod is driven by the hydraulic motor, the rotation directions of the smashing cutters can be adjusted therefore, and work efficiency is increased.
Description
technical field [0001] The invention relates to an agricultural machine, in particular to a straw returning device. Background technique [0002] In traditional agricultural production, crops, such as corn, cotton, rape, sorghum, rice, wheat, etc., will have a lot of straw scattered on the ground after harvesting, and the straw needs to be removed from the field so as not to hinder the planting of the next crop. However, crop straw The removal process is time-consuming and laborious, and the removed straw is often discarded or burned nearby, resulting in waste of resources and air pollution. For this reason, a lot of automatic straw returning devices have occurred. [0003] For example, in the patent application document with the application number of 200810024456.6 and the application date of 2008.3.21 and the publication date of August 20, 2008, a straw returning plowing machine is disclosed, which includes a hitch device, an intermediate transmission device, a gear , ch...
