Description

Technical Field

[0001] The present application relates to the technical field of rotary tillers, and in particular to a rotary tiller tool holder structure. Background Art

[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete ploughing and harrowing operations. It has been widely used because of its strong soil crushing ability and flat surface after plowing. It can also cut up the root stubble buried below the surface, which is convenient for the planter to operate and provides a good seed bed for later sowing. At present, when plowing, a rotary tiller mainly breaks up the land through a rotary tiller blade holder. However, in actual use, it is found that most of the existing rotary tiller blade holders are integrated structures, so that the spacing between the rotary tillers on the rotary tiller blade holder is constant, which is not conducive to adjusting the spacing between the rotary tillers, and thus cannot meet the tillage requirements of the land. Therefore, a rotary tiller blade holder structure is proposed to solve the problems described in the above background technology.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0007] Preferably, the plurality of movable rings are sleeved on the knife shaft at equal distances, and the plurality of movable rings are sleeved on the outer sides of the slide grooves on both sides.

[0008] Preferably, the slider and the limiting seat are arranged correspondingly, and the locking bolt fixes the slider on the limiting seat.

[0009] Preferably, the limiting seats on both sides are arranged between a plurality of mounting seats, and the plurality of mounting seats are equidistantly arranged on the movable ring.

[0010] Preferably, the rotary tiller blades are fixed to the mounting bases by bolts respectively.

[0011] In summary, this application includes the following beneficial technical effects:
