Turning shovel soil loosening device for sloping field

Abstract

The invention relates to a turning shovel soil loosening device for a sloping field, which comprises a vehicle body, four walking wheels, a first turning shovel and a second turning shovel. The first turning shovel and the second turning shovel are arranged in the vehicle body and extend out of the bottom end face of the vehicle body, and each walking wheel comprises a hollow wheel shell and a radius adjusting unit which is installed in the hollow wheel shell and can increase the radius of the corresponding walking wheel. The first turning shovel and the second turning shovel are installed in the vehicle body through an installation unit with the left-right height adjustable. When the soil loosening device turns soil on an inclined slope, the radius adjusting unit can adjust the size of the wheel on one side according to the gradient and the direction, it is guaranteed that the vehicle body is always kept horizontal and does not turn on one side, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of soil turning, in particular to a turning and shovel loosening device for sloping land. Background technique [0002] According to the "China Statistical Yearbook 2011" data, China's arable land area is 121.72 million hectares, accounting for 12.68% of the country's land area. The total amount of arable land in China ranks fourth among countries in the world, while the per capita arable land is only one-third of the world average. Moreover, the terrain of China is high in the west and low in the east. Mountains, plateaus and hills account for about 67% of the land area. Due to the rugged mountains, inconvenient transportation, and the large slope of sloping terrain, it is not conducive to the development of large-scale agricultural planting and the use of automated agricultural equipment. Most of the widely used agricultural machinery cannot be applied to the steep sloping land, resulting in the slow deve...

Moreover, China's terrain is high in the west and low in the east, with mountains, plateaus and hills accounting for about 67% of the land area. The cultivated land in the hilly areas is rugged due to the mountains, inconvenient transportation, and steep slopes, which are not conducive to the development of large-scale agricultural planting and the use of automated agricultural equipment. Most of the widely used agricultural machinery cannot be applied to steep slopes, resulting in the slow development of agriculture in hilly areas. Although micro-tillage machines are used for farming in some areas, micro-tillage machines are still only suitable for flat farmland, and they are useful on steep slopes. risk of rollover

[0003] Most of the farming machines are rotary tillage. This kind of tillage can achieve the benefits of leveling the surface, finely crushing the soil, and saving time and labor. Therefore, it is widely used. However, the depth of rotary tillage is often too shallow, and the average cultivation layer is less than 20 cm. Moreover, when the soil is too finely divided, the soil aggregate structure is destroyed, the capillary pores in the soil are less, and the ventilation, water permeability, and warming properties are poor. After it rains, it is easy to block the pores and cause the soil surface to crust.
