Connecting rod mechanism

Abstract

The invention discloses a connecting rod mechanism, which is used for connecting a powder ridge head with a drill stem and a support table. The connecting rod mechanism comprises a base, an oscillating element, a main connecting rod and a driven connecting rod, wherein the base is arranged on the support table; the oscillating element is rotationally arranged on the base; one end of the main connecting rod and one end of the driven connecting rod are rotationally connected with the oscillating element respectively; the other ends of the main connecting rod and the driven connecting rod are respectively connected with the powder ridge head; the main connecting rod, the driven connecting rod, the oscillating element and the powder ridge head are arranged on four sides of a first parallelogram, respectively; the main connecting rod can rotate relative to the oscillating element; and the drill stem is moved to a preset position in the direction vertical to the operation plane of the drill stem. The connecting rod mechanism disclosed by the invention is simple in structure; the powder ridge head can rotate to the preset position, so that the drill stem arranged on the powder ridge head can carry out linear movement in the direction vertical to the operation plane of the drill stem and is prevented from being damaged when entering into the earth obliquely.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a link mechanism of a subsoiler. Background technique [0002] In the past, loose plowing was achieved by hoes or oxen plowing, but no matter which of the above methods is not only laborious, but also inefficient. Therefore, for a large area of ​​land that needs loose plowing, the traditional method can no longer be adapted. Therefore, , there have been many automated tillers. [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 synergistic effect of the two oil cylinders, the auger rod can be used to plow the soil deeply. When the rod mechanism drives the auger rod to enter the soil obliquely, it is easily bent by the radial force, and i...

[0002] In the past, loose plowing was achieved by hoes or oxen plowing, but no matter which method is used, it is not only laborious but also inefficient. Therefore, for large areas of land that need loose plowing, the traditional method can no longer be adapted. Therefore, , there have been many automated tillers

[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. It is specifically disclosed that a link mechanism is set between the frame and the auger rod. , the connecting rod mechanism includes two oil cylinders, through the synergistic effect of the two oil cylinders, the auger rod can be used to plow the soil deeply. The rod mechanism drives the auger rod to enter the soil obliquely, it is easily bent by the radial force, and in more severe cases, it will break, which will affect the service life of the auger rod. At the same time, the effect of deep plowing is not good
