Description

Incomplete gear driven cultivating soil beating machine

technical field

The invention relates to an agricultural soil working machine, in particular to an incomplete gear-driven cultivating and beating machine for cultivating and cultivating soil.

Background technique

Cultivation and cultivating soil is a very important field management measure in the process of crop growth. It can improve soil environmental conditions and adjust soil water, fertilizer, air and heat conditions. Increase the air permeability of the soil, improve the oxygen supply of the root system, and ensure the normal physiology of the root system of crops.

Now when most of the rural areas are planting crops, most of them are manually digging and cultivating soil, which is labor-intensive, low in production efficiency, and poor in operation effect. In order to meet the needs of agricultural development, a series of cultivating soil cultivators have gradually appeared. According to the different ditching methods, it can be roughly divided into two categories, one is to use ditching coulters, and the soil is pushed to the ridges on both sides through the side of the coulters, and the other is to use disc-type ditching knives, most of which are single The shaft and the disc ditching knife rotate to cut the soil and throw it outward, and the soil is sent to the ridges on both sides under the guidance of the soil-building board. These two types of models do not compact the ridge surface, and it is easy to collapse and slide in rainy weather, and the crops are easy to fall, which affects the yield of crops, and the single tiller shaft is easy to wrap grass and cause insufficient power to stop.

Contents of the invention
