Rotary tiller with tilting cutter

Abstract

The invention discloses a rotary tiller with a tilting cutter. The rotary tiller comprises a power device, a traction wheel, a rotary tilling knife and a transmission case which is used for receiving power output from the power device and separately transmitting the power to the traction wheel and the rotary tilling knife. The axis of the rotary tilling knife is arranged along the direction of advance of the rotary tiller, the outer end of the rotary tilling knife tilts down so as to enable the axis of the rotary tilling knife to form an included angle with the horizontal plane, and thus the tilth of the rotary tiller is effectively increased; and meanwhile, during the soil cutting of the rotary tilling knife, a counteracting force along the axial direction of the cutter will be generated and has a pushing force enabling the rotary tiller to advance and a lifting force enabling the rotary tiller to rise, so that the rotary tiller can be effectively prevented from being deeply trapped during the tilling of marshy lands or deepwater fields.

Description

technical field [0001] The invention relates to the field of soil tillage machinery, in particular to a rotary tiller with inclined cutters. Background technique [0002] In the prior art, agricultural mechanized production mainly uses plowing, harrowing and rotary plowing for soil cultivation. Plowing mainly uses a traction mechanism to pull the plowshares to turn the land to achieve the purpose of plowing. Harrowing mainly uses traction. The mechanism pulls tools such as disc harrows, spike-toothed harrows, or paddy field star harrows to cultivate the soil surface, which is usually a finely broken and leveled intensive cultivation operation on the land after plowing. Rotary tillage mainly uses the rotation of the cutter to cut the land to complete related operations. In mountainous and hilly areas, small gasoline engines or small diesel engines are usually used as a series of walking farming farming machinery powered by small gasoline engines. This small rotary tiller Gen...

Rotary tillage mainly uses the rotation of the cutter to cut the land to complete related operations. In mountainous and hilly areas, small gasoline engines or small diesel engines are usually used as a series of walking farming farming machinery powered by small gasoline engines. This small rotary tiller Generally, there is no special traction mechanism. When working, the reaction force generated when the tool is rotated to cut the soil is used as the traction force to move forward. This reaction force is relatively small when cultivating muddy land or deep water fields, which is not enough. When the traction machine moves forward, a deep sink will occur. Once a deep sink occurs, there is no other way than manual rescue, and a small number of rotary tillers equipped with traction wheels and other traction mechanisms have the axis of the rotary tiller along the forward direction. It is set horizontally, therefore, the height of the rotary tiller relative to the ground is relatively high. When cultivating the soil, the soil tillage depth is relatively shallow, and it is difficult to reach the tillage depth required for planting. Therefore, it is necessary to use a rotary tiller with a long rotary tiller blade. Only the cutting tool can meet the requirement of plowing depth. In addition, since the rotary tiller cannot provide upward lifting force for the rotary tiller, when the traction wheel is deeply sunken, manual rescue can only be relied on.
