Ridge crusher for subsoiling and ridge crushing machine

Abstract

The invention discloses a ridge crusher for a subsoiling and ridge crushing machine. The ridge crusher comprises a ridge crushing box with a bottom plate, side plates and a top plate, rib plates are welded among lower bearing seats which are mounted on the bottom plate, a lubricating oil passage is reserved between each rib plate and the bottom plate, and upper bearing seats mounted on the top plate are longer than the lower bearing seats. The ridge crusher for the subsoiling and ridge crushing machine has the advantages that strength of the lower bearing seat can be improved, more bearings can be mounted at high-load-bearing positions while less bearings are mounted at low-load-bearing positions, and accordingly rigidity and transmission stability of a transmission shaft are improved, and cost is reduced; in addition, welding of the rib plates is facilitated, and smooth flow of lubricating oil in the ridge crushing box is guaranteed so as to improve lubrication effects.

Description

technical field [0001] The invention relates to a loose tillage powder ridge machine, especially a powder ridge device. Background technique [0002] The main function of loose plowing powder ridge machine is to loosen and crush the land. In the past, loose plowing and crushing were realized by hoes or cattle plowing, but no matter which of the above-mentioned traditional methods, it is not only laborious but also inefficient. Therefore, For a large area of ​​land that needs to be plowed and crushed, the traditional method has been unable to adapt. For this reason, the current automatic plowing machine has appeared. For example, the application number is 201020514808.9, the application date is 2010.9.3, and the authorization announcement date is 2011 Disclosed in the patent literature on July 20, 2010 is a kind of rotary grinding type deep plowing powder ridge multifunctional machine. Also disclose a kind of spiral type subsoiling cultivator in the patent document that the ...

AI Technical Summary

Problems solved by technology

[0004] When the powder ridge device is used to loosen the powder ridge, the auger rod will be subjected to axial force and radial force, and the auger rod is connected to the transmission shaft of the transmission system, so the lower end of the transmission shaft will also be subject to greater force. Large axial force and radial force, therefore, the general transmission shaft is installed on the fan box through the bearing, the powder box is also used to install the transmission system, and forms a lubricating oil tank, so that it will be on the upper end of the powder box and the lower end are provided with bearing housings respectively, and the existing bearing housings and the powder ridge box have an integrated structure, so it is difficult to manufacture and the cost is high

[0005] In addition, in order to increase the number of supporting points for the transmission shaft and improve the rigidity of the transmission shaft, multiple bearings are usually installed, and sometimes multiple bearings are installed on the same bearing seat. Then, the height of this bearing seat is relatively large, and its strength hard to guarantee

[0006] Most of the cutting tools of the existing tiller are auger rods. During the loosening process, the rotation of the auger rod will be subjected to the reverse resistance of the land. Therefore, power output often occurs, but the auger rod is stuck. It cannot rotate or the speed of rotation is slowed down. In this way, not only can the loose tillage be continued or the effect of loose tillage will be poor, but also the life of the driving mechanism will be shortened or the driving mechanism will be directly damaged.
