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 authorization announcement date is 2011.2.16, a rotary milling type powder ridge multifunctional machine is disclosed. There is a linkage rotary grinding drill device, which is equipped with multiple drill shafts. There is only one helical blade on the drill shaft. This single helical blade is relatively easy to uplift large pieces of soil, and another helical blade on the drill shaft is required to cooperate with the crushing Soil, which is not only complex in structure, but also time-consuming

Embodiment Construction

[0019] see figure 1 , in a preferred embodiment of the present invention, a tiller bit structure 100 includes a connecting flange 10, a drill rod 20, a drill bit 30, a left helical blade 40, a right helical blade 50 and several drill bits 60.

[0020] The connecting flange 10 defines a plurality of screw holes 11 and extends downwards with a neck 13 for connecting the drill rod 20 . In one embodiment, the number of the screw holes 11 is two, and the outer diameter of the neck 13 is smaller than the outer diameter of the connecting flange 10 . The connecting flange 10 is locked into the screw hole 11 and the output shaft (not shown) of a powder ridge box through a locking member, such as a screw, so that the tiller drill bit structure 100 is installed on the powder ridge on the box.

[0021] The drill rod 20 is in the shape of a strip, one end of which is fixed to the connecting flange 10 through the neck 13 , and the other end is connected to the drill bit 30 . In this emb...

Abstract

The invention discloses a sub-soiling cultivator drill bit structure which comprises a connecting flange, a drill rod and a drill bit, wherein the connecting flange is arranged at one end of the drill rod, and the drill bit is arranged at the other end of the drill rod. The sub-soiling cultivator drill bit structure is characterized by further comprising a left spiral blade and a right spiral blade which are arranged on the periphery of the drill rod in a staggered manner. The left spiral blade and the right spiral blade simultaneously act and can crush soil to be thin once in the sub-soiling process, the sub-soiling cultivator drill bit structure is simple, and time is saved.

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 grinding drill device, which is equipped with multiple drill shafts. There is only one helical blade on the drill shaft. This single helical blade is relatively easy to uplift large pieces of soil, and another helical blade on ...
