[0004] The above-mentioned ridging rotary cultivator needs to be connected with the corresponding engine before it can be used. In this way, the structure of the ridging rotary cultivator must be equipped with a corresponding reduction box, gear box and transmission shaft, which makes its structure more complicated. And the cost is high, which will increase the burden on farmers

The invention discloses a pulling frame of a rotary cultivator. The pulling frame is characterized in that the pulling frame is in a T shape integrally and is formed by a longitudinal rod and a transverse rod, one end of the longitudinal rod is vertically and fixedly connected with the middle of the transverse rod, the other end of the longitudinal rod is used for being connected with a tractor, and the two ends, in the length direction, of the transverse rod are hinged to a rack of the rotary cultivator. The pulling frame is simple in overall structure, by means of the structure of connecting the two ends, in the length direction, of the transverse rod to the rack in a hinge joint mode, the pulling frame adapts to the vertical bumping state in the forward motion process of the tractor on field soil better, and pull force of the forward motion of the tractor can be transmitted continuously and stably through the pulling frame to pull the rotary cultivator to move forward stably and cultivate the soil. In addition, the pulling frame has the advantages of being reasonable in structure, lower in manufacturing cost and convenient to manufacture.
Description
technical field [0001] The invention belongs to the field of tillage machinery, and in particular relates to a support frame of a rotary tiller. Background technique [0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil breaking ability and flat surface after plowing. At the same time, it can chop up the root stubble buried below the surface, which is convenient for the seeder to operate and provides a good seed bed for later sowing. [0003] At present, most of the rotary tillers in the prior art are driven soil tillage machines with rotating cutter teeth as the working parts, such as the ridge rotary tiller disclosed by the patent with the notification number CN203251582U. The ridge rotary tiller includes a frame main body , the reduction box arranged in the middle of the front of the main body of the frame, the gear transmissions arranged symmetrically ...
