Vertical rotary tiller for promoting rock to form soil on purple soil thin layer slope

Abstract

The invention discloses a vertical rotary tiller for promoting rock to form soil on a purple soil thin layer slope. The vertical rotary tiller comprises a rack and a spiral device, wherein a case is arranged at the top end of the rack, and a generator is arranged in the case; an oil tank is arranged at the top end of the case, and a water tank is arranged at one side of the oil tank; the spiral device is arranged at one end of the rack, and the top end of one side of the spiral device is fixedly provided with a push rod; the bottom of the other end of the rack is welded with a rotating shaft,and the two ends of the rotating shaft are respectively connected with the inner ring of a rolling bearing in a penetrating way. The mud and the shale on the purple soil thin layer slope are spirallyground and crushed by the spiral device to promote the weathering of parent rock into soil and reduce the tillage erosion so that the soil formation rate is greater than the erosion rate and the soillayer thickness is increased, the deep tillage is performed but a soil layer is not disturbed, and a U-shaped groove is formed in a soil deep layer after the tillage is performed by a spiral shaft toeffectively gather interflow. The vertical rotary tiller can complete the traditional plowing, raking and beating operation procedures once, and is favorable for water, gas fertilize balance in the soil through live soil water retention.

Description

technical field [0001] The invention relates to the technical field of agricultural tillage machinery, in particular to a vertical rotary tiller for promoting rock formation on sloping fields with thin layers of purple soil. Background technique [0002] There are more than 20 million hm2 of purple soil resources in my country. Purple soil slope farmland has the characteristics of extremely fast soil formation rate and shallow soil layer. In actual production, the upper part of most slope land always maintains a soil layer thickness of 10-20cm. This thickness basically depends on the cultivation depth. The thickness required for productivity varies widely. Purple soil sloping cultivated land also has the characteristics of short slope and large slope, and the cultivation intensity is high. Intense tillage not only directly causes the loss of soil and its nutrients from the upper part (convex slope) of the sloping farmland, but also transfers a large amount of upslope soil ...

Problems solved by technology

[0003] In order to solve the defect that the existing farming machinery in the prior art can only maintain the balance of the two processes of promoting rock formation and tillage erosion, and it is difficult to break the balance to improve the thickness of the soil layer and the productivity of the land, the present invention provides a purple soil thin layer slope land Vertical Rotary Tiller for Promoting Rock and Soil Formation
