Small vertical shaft type deep cultivator

Abstract

The invention relates to a small vertical shaft type deep cultivator. The cultivator solves the problem of shallow tillage in hilly mountainous areas, has a good effect of upswing and loosening, can break a plow bottom layer uncultivated for many years, and improves the ability of soil water storage and moisture conservation, the energy consumption is low, and the size of a whole machine is small.According to the following scheme, the small vertical shaft type deep cultivator includes a power device, a walking wheel, a transmission box, two vertical shaft segmented non-continuous spiral cutters, a tillage depth adjusting device and the like. The two vertical shaft segmented non-continuous spiral cutters have the same shape and dimensions and are arranged perpendicular to the forward direction of the deep cultivator. The segmented non-continuous spiral cutters consist of blade shafts and three spiral blades which are evenly distributed in the axis. A hexagonal square hole is formed inthe center of a cutter head for connecting the entire cutter head to a power output shaft; three square holes are evenly distributed in the circumferential direction of the cutter head, and the threesegmented non-continuous spiral cutters are fixedly installed on the cutter head through bolts and the three square holes.

Description

technical field [0001] The patent of the invention belongs to the field of agricultural tillage machinery, and in particular relates to a small vertical shaft deep cultivator. Background technique [0002] Deep plowing and subsoiling are one of the important contents of agronomic farming requirements. Deep plowing can provide a deep plow layer for crop growth, accelerate nutrient decomposition and accumulation, promote soil maturation, improve soil water storage and moisture retention capacity, and increase crop yield. Due to terrain constraints, micro-tillers are usually used for farming in hilly and mountainous areas, but the actual plowing depth of most micro-tillers is only 10-15cm. Therefore, long-term shallow plowing and shallow farming have brought new problems: a hard plow layer appears at the bottom of the plow layer, Soil compaction seriously affects the development and rooting of crop roots; due to long-term shallow cultivation, the ability of soil to preserve fer...

Problems solved by technology

Due to terrain constraints, micro-tillers are usually used for farming in hilly and mountainous areas, but the actual plowing depth of most micro-tillers is only 10-15cm. Therefore, long-term shallow plowing and shallow farming have brought new problems: a hard plow layer appears at the bottom of the plow layer, Soil compaction seriously affects the development and rooting of crop roots; due to long-term shallow cultivation, the ability of soil to preserve fertilizer and entropy decreases, and the utilization rate of fertilizer is low; the water storage and water retention capacity of compacted land is weakened year by year, and the ability of crops to resist drought and lodging is poor; soil aeration The temperature is reduced, the aerobic microorganisms are reduced, and the crop diseases and insect pests are increased

However, deep plowing units mounted on large and medium-sized tractors are bulky and heavy, and cannot adapt to the terrain conditions of hilly and mountainous areas.
