Description

Technical Field

[0002] As a component of agricultural machinery, rotary tillers play an important role in the tillage and harrowing operations of farmland. Rotary tillers are driven and pulled by tractors to complete the tillage and harrowing operations. At present, the horizontal rotary tillers commonly used in the farmland industry mainly include side-drive rotary tillers and intermediate-drive rotary tillers. Since side-drive rotary tillers have the advantages of avoiding missed tillage and good soil crushing effect, they are gradually accepted by users. Existing side-drive rotary tillers have the following defects: (1) Because the intermediate gear in the gear box is too large, it is easy to cause the rotary tiller to be uneven on the left and right and the tilled land to be uneven; (2) The side plows on both sides of the rotary tiller are easy to break; (3) The axial positioning of the speed regulating gear is unreasonable, and it is directly limited by the rear cover of the box. During operation, the friction between the end face of the gear and the rear cover of the box increases power consumption, easily generates heat and generates noise; after a long period of operation, the gap between the gear and the rear cover of the box increases, and the gear is easy to move axially, resulting in incomplete meshing of the gear and uneven wear, thereby reducing the strength and service life of the gear.
