Traction device for agricultural machinery

Abstract

The invention discloses a traction device for agricultural machinery. The traction device comprises a machine frame and a machine body; and a connecting frame is positioned and connected to the left side of the machine body, a first connecting block is movably arranged in the connecting frame, a connecting rod is positioned and connected to the left side of the first connecting block, a second connecting block is movably arranged at the left end of the connecting rod, a third connecting block is movably arranged at the left side of the second connecting block, a shock absorber is arranged on the outer side of the machine body, and an external frame is arranged on the outer side of the machine body. According to the traction device for agricultural machinery in the invention, the third connecting block which is not matched with the shape of the connecting part of an auxiliary machine body can be replaced at any time by movably installing the third connecting block on the left side of the second connecting block, so that the traction device can be matched with the shape of the connecting part of the auxiliary machine body without the need of replacing the whole traction device, suchthat the use cost can be saved, and the waste of resources is avoided; and the traction device can be matched with a traction machine of the same type through the external frame to achieve butt jointwith a large machine, so that the traction device is more conveniently used.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a traction device for agricultural machinery. Background technique [0002] With the continuous advancement of science and technology, small-scale agricultural production and gardening industries continue to use new mechanical devices for production work. The traction device is often used for the connection between the main body and the auxiliary body to ensure the connection between the main body and the auxiliary body. stability, but the shape of the part connected to the auxiliary body and the traction device is different. There are ring-shaped and hole-shaped ones. Due to structural reasons, the shape of the traction device is relatively simple, and the part connected to the auxiliary body cannot be replaced. , to cooperate with the sub-body that does not match the connecting part, only the entire traction device can be replaced. This method will increase the cost of use...

[0002] With the continuous advancement of science and technology, small-scale agricultural production and gardening industries continue to use new mechanical devices for production work. The traction device is often used for the connection between the main body and the auxiliary body to ensure the connection between the main body and the auxiliary body. stability, but the shape of the part connected to the auxiliary body and the traction device is different. There are ring shapes and holes. However, due to structural reasons, the shape of the traction device is relatively simple, and it is impossible to replace the part connected to the auxiliary body. , if you want to cooperate with the auxiliary body that does not match the connection part, you can only replace the entire traction device. This method will increase the cost of use, cause a waste of resources, and is not convenient for people to use
