Worm and gear angle adjusting mechanism of plough share

Abstract

A worm and gear angle adjusting mechanism of a plough share comprises a worm and gear shell, a worm gear shaft, a worm gear and the plough share. A first bearing is installed in a bearing hole in the outer end of the right side of the worm and gear shell, and a second bearing is installed in a bearing hole in the outer side of a big end cover of the shell. The two ends of the worm gear shaft are supported through the first bearing and the second bearing respectively. A third bearing is installed in a bearing hole in the right side of the worm and gear shell, a fourth bearing is installed in a bearing hole in the inner side of the big end cover, and the worm gear is supported and positioned through the third bearing and the fourth bearing. The left end of the worm gear shaft is fastened by a shaft fixing cover, a gear gasket is fixed to the bearing hole position of the outer end, close to the right side of the worm and gear shell, of the worm gear shaft, and the outer end of the worm gear shaft is fixedly connected with one end of a connecting lever. The other end of the connecting lever is fixedly connected with the plough share, the worm gear and a worm are mutually meshed, and the two ends of the worm are supported through a fifth bearing and a sixth bearing respectively. The worm and gear angle adjusting mechanism is simple in structure and practical, and the plough share can be adjusted within a certain angle range and can be positioned and locked.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a plow share worm gear angle adjustment mechanism. Background technique [0002] In Northeast China, the traditional farming methods are stubble cutting, stubble breaking, and soil moisture. On hilly slopes, mechanized stubble removal is limited, especially on slopes above 20 degrees. The farmer brothers have created a new farming method, which solves the problem of stubble removal on sloping land, by cutting off the stubble directly and cultivating on the half. [0003] In the past, livestock plows were used for half of the deduction. If a walking tractor was used, people had to be pulled on the hillside, and the slope was too steep to be cultivated. With the promotion and popularization of micro tillage machines, farmers have solved the problem of cultivating hillside land. However, there are still many problems in the existing micro tillage machines. It can not be adjusted inside,...

AI Technical Summary

Problems solved by technology

[0003] In the past, half of the plows were plowed by livestock. If you use a walk-behind tractor, you have to use people to pull it on the hillside. The slope is too steep and cannot be cultivated.

With the promotion and popularization of micro-tillers, farmers have solved the problem of cultivating hillside land. However, there are still many problems in existing micro-tillers. It cannot be adjusted inside, and the plowshare cannot be positioned and locked, which brings a lot of inconvenience to farmers
