A transmission shaft device for swing arm type machinery

Abstract

The invention discloses a transmission shaft device for swing arm type machinery, relates to the technical field of swing arm type machinery, and solves the problem that the existing swing arm type lawn mower has a circular mowing boundary, which is very inconvenient when mowing grass in a square area ,The problem. A transmission shaft device for a swing arm type machine, comprising an inner arm of a mechanical arm; the inner arm of the mechanical arm is inserted into the shell of the outer arm of the mechanical arm. When the device cuts grass, the mowing radius is square. When the outer arm of the mechanical arm rotates, the inner arm of the mechanical arm can extend outward, so that the mowing path of the inner arm of the mechanical arm can move along a straight line when the outer arm of the mechanical arm rotates. , so that it can better adapt to the harvesting of grass, the harvesting is more thorough, convenient and flexible, and the flexibility and practicability of the device are improved.

Description

technical field [0001] The invention belongs to the technical field of swing arm type machinery, and more specifically relates to a transmission shaft device for swing arm type machinery. Background technique [0002] Swing arm type agricultural machinery, such as lawn mowers, rotary tillers, etc., the angle of the mechanical arm can be adjusted to obtain different working areas or facilitate transportation and transfer. [0003] For example, in the patent with the application number: CN201820322066.6, a swing arm type agricultural machinery transmission shaft device is disclosed, including a suspension frame, a frame, and a transmission shaft. The transmission shaft includes a first transmission shaft, a second transmission shaft shaft, the front end of the first transmission shaft is the power connection end, the rear end of the second transmission shaft is connected to the power input end of the frame, the rear end of the first transmission shaft and the front end of the ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a transmission shaft device for a swing arm type machine to solve the problem that although the mechanical arm of the existing swing arm type lawn mower can rotate the swing arm to mow grass, when the mechanical arm swings, the pin shaft is used as the The center of the circle rotates, and the mowing boundary is circular, which is very inconvenient when mowing a square area. It is necessary to adjust the angle and position of the mowing robot arm many times to mow the grass thoroughly. The steps are cumbersome and the practicability is not high.
