Novel rotary blade

Abstract

The invention provides a novel rotary blade, and relates to the technical field of agricultural machinery. The novel rotary blade is applicable to a rotary cultivator for tilling a thin purple soil slope land and comprises arc-shaped hollowed-out blades, horizontal supports, spud piles, a rotating shaft and mounting holes. The middles of the arc-shaped hollowed-out blades are connected through thehorizontal supports, the arc-shaped hollowed-out blades are connected onto the spud piles through threaded fasteners, the spud piles are connected onto the rotating shaft in a welded mode, the six arc-shaped hollowed-out blades are mounted on the rotating shaft, and the mounting holes are formed in two ends of the rotating shaft. According to the rotary blade, tillage translocation and tillage erosion can be decreased, tillage depth and crushing degree are increased, weathering of deposited loose purple mud shales into soil is promoted, and soil depth and soil productivity are further increased.

Description

technical field [0001] This patent relates to a novel rotary tiller, especially a rotary tiller suitable for tilling thin purple soil slopes. Background technique [0002] The purple mud shale is loosely deposited and easily broken by mechanical force. When the purple soil slope is cultivated, over-cultivation and unreasonable farming methods will aggravate the thinning and poverty of the soil layer, thereby reducing land productivity. In real life, the upper part of most slopes always maintains a soil layer thickness of 10-20cm, which basically depends on the depth of cultivation. The traditional ox-pull plow, hoeing and other plowing processes will cause downhill displacement of the soil, which will aggravate soil erosion; the rotary tiller always produces uphill displacement and downhill displacement during a single tillage process, and uphill displacement Always less than the downslope displacement, a single tillage would produce a net downward displacement, resulting i...

AI Technical Summary

Problems solved by technology

[0003] In view of the above problems in the prior art, this patent provides a new type of rotary tiller, which solves the problem of thinning of the soil layer due to tillage erosion and shallow tillage depth in the existing rotary tiller, and the increase in the number of tillage due to poor crushing effect. , which is not conducive to the problem of soil fertilizer and water conservation and production increase
