All-terrain flexible rotary tillage knife

Abstract

The invention specifically discloses an all-terrain telescopic rotary tiller, including a cutter disc fixedly connected to the shaft of the rotary tiller, and a rotary tiller blade. There are four rotary tiller blades, and the four rotary tiller blades are fixedly arranged on one side of the disc surface of the cutter disc. , the four rotary tillage blades are evenly distributed along the circumference of the cutter head, the rotary tiller blades are L-shaped, the rotary tiller blades include the tail of the knife and the blade for tilling the land, and the tail of the knife is movably hinged on the cutter head; four The rotary tiller blades are fixedly provided with tension springs between each other. When the rotary tiller is subjected to greater resistance or when the resistance changes due to the unevenness of the land, the rotary tiller blades hinged on the cutter head can offset the changed resistance through stretching springs, thereby enhancing the rotary tillage. The stability of the knife group when working. At the same time, due to the effect of the tension spring, the rotary tiller shaft is not easy to jump.

Description

technical field [0001] The invention relates to the technical field of tillage machines, in particular to an all-terrain telescopic rotary tiller. Background technique [0002] The agricultural micro-rotary tillers in the prior art generally adopt small-sized rotary tillers, which are widely used because of their small size and convenient operation. The rotary tiller drives the all-terrain telescopic rotary tiller group through a power device to complete the work of cultivating the land. The all-terrain telescopic rotary tiller set includes a rotary tiller shaft and rotary tiller blades fixedly arranged on the rotary tiller shaft. At least three rotary tiller blades are evenly arranged in the circumferential direction of the rotary tiller shaft. Complete self-propelled and cultivated land. [0003] The rotary tiller blades of this type of rotary tiller are generally directly fixedly connected to the rotary tiller shaft. Since the rotary tiller blade itself is very long, th...

AI Technical Summary

Problems solved by technology

[0003] The rotary tiller blades of this type of rotary tiller are generally directly fixedly connected to the rotary tiller shaft. Since the rotary tiller blade itself is very long, the following problems occur when the all-terrain telescopic rotary tiller is working: the all-terrain telescopic rotary tiller The stability is extremely poor during work, and the beating is serious, which makes the operator laborious to control

However, the rotary tiller blade should not be too short, because it is easy to cause the rotary tiller blade to be unable to cultivate the land
