A drill bit structure of a tiller

Abstract

The invention discloses a subsoiling machine drill structure, which comprises a connecting flange, a drill pipe, a drill body, a plurality of drilling tools and at least one spiral blade, wherein the connecting flange is arranged on one end of the drill pipe; the drill body is arranged on the other end of the drill pipe; the drilling tools are respectively installed on at least one spiral blade; at least one spiral blade is arranged on the periphery of the drill pipe; the diameter of the spiral blade gradually reduces from the drill body to the connecting flange. In the subsoiling machine drill structure disclosed by the invention, at least one spiral blade upwards ridges soil and is cooperated with the drilling tools to cut and rub the soil so as to realize a purpose of soil smashing. In addition, the diameter of at least one spiral blade gradually reduces from the drill body to the connecting flange, i.e. a drilling tool on the lower end of the subsoiling machine drill structure has a high linear speed, and the subsoiling machine drill structure can smash the clumps of special cultivated lands, such as salt and alkali zones and conforms to agricultural requirements.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a drill bit structure of a tiller. Background technique [0002] The traditional deep plowing and deep loosening process is plowing, beating, and harrowing, which is not only laborious, but also complicated and inefficient. Therefore, for large-area land that needs to be plowed loosely, traditional methods have been unable to adapt. For this reason, many automated plow tillers have appeared. [0003] For example, in the patent document whose application number is 201010270614.3, the application date is 2010.9.3, and the authorization announcement date is 2011.2.16, a rotary milling type powder ridge multifunctional machine is disclosed. There is a linkage rotary abrasion drill device, which is equipped with one or more drill shafts, on which a helical leaf is arranged, and the width of the helical leaf is constant, therefore, the crushing effect of the helical leaf on the surface soil ...

Problems solved by technology

[0002] The traditional deep plowing and subsoiling process is plowing, beating, and harrowing, which is not only laborious, but also complicated and inefficient

Therefore, for a large area of ​​land that needs to be plowed, the traditional method has been unable to adapt. For this reason, many automated plowing machines have appeared.

[0003] For example, in the patent document whose application number is 201010270614.3, the application date is 2010.9.3, and the authorized announcement date is 2011.2.16, a rotary milling type powder ridge multifunctional machine is disclosed. There is a linkage rotary abrasion drill device, which is equipped with one or more drill shafts, on which a helical leaf is arranged, and the width of the helical leaf is constant. Therefore, the crushing effect of the helical leaf on the surface soil and deep soil is Consistent, cannot meet the agricultural requirements for surface soil and deep soil thickness

In addition, for some special cultivated lands such as saline-alkaline areas, the hardening below is very serious, and the hardening cannot be broken through the above-mentioned spiral blades.
