Technical Field
The invention belongs to agricultural machinery, and mainly relates to a quick traction connecting device of a traction type agricultural machine and a traction power machine.
Background
In recent years, with the continuous increase of the area of a single piece of land in China and the improvement of the level of agricultural mechanized operation, various large-scale traction type agricultural machines are successfully researched and developed, are widely popularized and applied in production operation, and play an active role in improving the agricultural mechanized operation efficiency and ensuring the operation quality. However, due to the structural design deficiency, when the large-scale traction type agricultural implement is connected with the traction tractor in a traction manner, the traction frame on the front side part of the large-scale agricultural implement must be manually lifted by manpower and continuously moved to be adjusted so as to align with the traction point on the rear side part of the traction tractor to complete the connection, which is labor-consuming, time-consuming and labor-consuming, i.e. labor waste, low operation efficiency and high labor intensity, is a technical problem to be solved.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and designs a quick traction connecting device for a traction type agricultural implement by combining the actual requirements of the connection of the current large traction type agricultural implement and a traction tractor, so that the aims of high connection operation efficiency, low labor intensity and labor saving are fulfilled.
