Soil drilling tool

Abstract

The invention relates to the field of agricultural tools, in particular to a soil drilling tool, which includes a cylindrical cylinder, the end of which is a cone structure, and two Semicircular steel blades, the angle between the two semicircular steel blades is between 30-90°, and the angle between the two semicircular steel blades and the axis of the cylinder is consistent, the two semicircular steel blades There is no staggered area in the projection of the shaped steel blades on the horizontal plane; a handle is arranged horizontally on the top of the cylinder. The obtained soil drilling tool of the present invention, when drilling soil holes, rotate the handle on the tool and give a certain pressure, pull out the tool vertically after rotating two or three times, discard and stick on two semicircular steel blades of soil and continue to repeat the process. This process is especially suitable for drilling soils with high water content or paddy fields. Application of the invention provides a punching tool, and the walls of the drilled soil holes are smooth and uniform.

Description

technical field [0001] The invention relates to the field of agricultural tools, in particular to a soil drilling tool. Background technique [0002] The existing punching tool is mainly used for planting and punching, and the punching depth is shallow. Although there are currently some spiral drilling tools that can drill soil holes of different depths according to requirements, they are mainly used in dryland soil or soil with low soil moisture content, and use the fast rotation power to spin the soil out of the hole. Even this still cannot meet the needs of drilling deeper soil holes (such as 1 meter to 1.5 meters or deeper), because the soil that is drilled too deep cannot be discharged from the hole. Moreover, when the water content of the soil is high and the hardness of the bottom soil is high, there are problems such as wet soil or soil being difficult to spin out and difficult to operate. [0003] Existing tools for punching soil round holes are mainly used for pl...

Problems solved by technology

Even this still cannot meet the needs of drilling deeper soil holes (such as 1m-1.5m or deeper), because the soil is too deep to be discharged out of the hole

Moreover, when the soil water content is high and the bottom soil hardness is large, there are problems such as wet soil or soil are difficult to spin out, and are difficult to operate (such as application number 201420557635.7, see figure 2 )

Application number: 201510489024.2, Invention name A kind of rotary soil hole machine (such as image 3 ) is also a rotary soil punching machine, but its main component 8 (turning plate) is set horizontally and is difficult to screw in. In addition, this punching machine uses the high-speed rotating rotating plate to completely mash the soil, and then reuses The rotary plate drags the crushed soil out of the hole. Since the rotary plate is a semicircular structure, the efficiency of the rotary plate is low when dragging the soil. At the same time, the original structure of the soil is completely destroyed.
