Description

technical field [0001] The invention relates to a shovel plate of a non-self-driven traction type rolling part used for processing soil surface micro-topography, in particular to a shovel plate with bionic geometric structure characteristics of the rolling part. It can be applied to the soil surface micro-topography processing rolling parts in agricultural machinery to enhance soil water storage and moisture retention capacity and prevent farmland water and soil loss. Background technique [0002] In most of the cultivated areas in my country, the rainfall is unevenly distributed in space and significantly different in time domain. When the rainfall intensity exceeds the soil infiltration intensity, surface runoff will be generated, causing erosion of the surface, and a large amount of sediment in the soil will be lost. , destroy soil structure and fertility and adversely affect crop yields. Soil surface microtopography processing is to process the micropit morphology on the...

Problems solved by technology

However, compared with the convex-tooth compactor, there are the following disadvantages in processing the microtopography of the soil surface with the machine: the machine is a driven tillage component, which requires additional drive output of the traction mechanism, which increases power consumption; The machine also needs to cooperate with complex control circuits and control mechanisms to work effectively, which increases the operating cost and maintenance cost of soil surface micro-topography processing; moreover, the shovel plate structure of the building machine is a regular rectangular steel plate with equal thickness Under hard and dense working conditions, the shovel plate of the construction machine is easy to bend, deform, or even break

More importantly, this operation method has the following problems: the building machine only has the function of processing micro-pits on the soil surface, but does not have the function of compacting the soil, and the excessively soft soil after the building operation will cause the soil moisture to evaporate too quickly , but reduces the ability of the soil to hold water; in addition, because the surface soil surface and the inner wall of the micro-pit processed by the machine are too loose, when rainfall or irrigation water flows into the micro-pit processed by the machine, The water flow will disperse the fine particles and organic matter on the soil surface and deposit them at the bottom of the micro-pits. After the rainfall or irrigation is completed, the soil fine particles and organic matter at the bottom of these micro-pits will gradually dry and harden, and form a thin layer at the bottom of the micro-pits. The dense soil layer will make it difficult for future rainfall or irrigation water to penetrate into the soil from the micro-pit, which will greatly weaken the effect of micro-topography processing on the soil surface to reduce soil erosion.

The machine tool can achieve excellent operating results in the cultivation areas with low soil firmness and soft soil. However, in some cultivation areas where the soil surface microtopography processing technology needs to be promoted, the soil is severely hardened due to drought and water shortage during the cultivation season. The hardened soil has high firmness and serious compaction, and it is difficult for the convex teeth to embed into the soil during operation, which significantly reduces the water storage capacity of the processed micro-pit, which restricts the operation effect of the micro-topography processing of the soil surface

Although increasing the pressure applied vertically to the soil by the convex teeth suppressor can make the convex teeth overcome the hard soil surface and form micro pits on the ground surface, which improves the water storage capacity of the micro pits to a certain extent, however, the firmer the soil The higher the pressure, the greater the pressure that needs to be increased. Excessively increased pressure will aggravate the compaction of the soil, and on the contrary make it difficult for the formed soil surface water to penetrate into the soil, making the formed soil conditions unsuitable for farming

In addition, excessive pressure will disturb the soil excessively, making the inner wall of the micropit easy to collapse, and the fine particles left on the soil surface will make the soil easy to be eroded
