a lift system

Abstract

The invention discloses a lifting system for lifting and lowering a powder ridge head with a drill bit, including a bracket, a guiding structure, a sliding structure and a limiting structure, the guiding structure is installed on the bracket, and the limiting structure is installed on the On the sliding structure, the sliding structure is slidingly engaged with the guiding structure, and has a locked state and a free state relative to the guiding structure; when the sliding structure is in the locked state, the limiting structure squeezes Pressing the sliding structure, when the sliding structure is in the free state, the limiting structure releases the sliding structure, and the sliding structure can slide relative to the guiding structure in a direction perpendicular to the working surface of the drill bit . In the lifting system of the present invention, the drill bit can move vertically into the soil along with the sliding structure in the direction of the vertical working surface, and squeeze the sliding structure through the limiting structure to prevent the sliding structure from deviating from the guiding structure, thereby improving the drill bit during the powder ridge process. stability.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a lifting system for a powder ridge head in a subsoiling deep cultivator. 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, a high-speed double-screw deep cultivator is disclosed in the patent document whose application number is 201220013529.3 and the application date is 2012.1.13 and the authorized announcement date is 2012.11.21. , the connecting rod mechanism includes two oil cylinders, through the synergy of the two oil cylinders, the auger bit can deeply plow the soil, however, in the process of deep plowing, the connecting rod mechanism drives the auger...

[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, a high-speed double-screw deep cultivator is disclosed in the patent document whose application number is 201220013529.3 and the application date is 2012.1.13 and the authorized announcement date is 2012.11.21. , the connecting rod mechanism includes two oil cylinders, through the synergy of the two oil cylinders, the auger bit can deeply plow the soil, however, in the process of deep plowing, the connecting rod mechanism drives the auger rod to enter the soil obliquely and is easily subjected to radial force The role of the auger becomes bent, and in more serious cases, it will break, which will affect the service life of the auger bit. At the same time, the effect of deep plowing is not good.
