Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] refer to Figure 1 to Figure 11 , a disc tractor connecting buckle with a locking function of the present invention, including a head connecting piece 1, an intermediate connecting piece 2 and a trailer connecting piece 3.

[0027] The intermediate connector 2 is rotationally connected with the headstock connector 1 through the first rotating shaft 4 arranged horizontally; the trailer connector 3 is rotationally connected with the intermediate connector 2 through the second rotating shaft 5, and the first rotating shaft 4 and the Reel 5 is always vertical. Specifically, the head connector 1 is plate-shaped and has four sides, two of which are parallel to each other, and one of the other two sides is a circular arc surface, and the other is perpendicular to the two parallel sides. One end close to the arc surface is provided with a head connec...

Abstract

The invention discloses a disc-type tractor connecting buckle with a locking function. The disc-type tractor connecting buckle comprises a tractor head connecting piece, a middle connecting piece anda trailer connecting piece, wherein the middle connecting piece is rotationally connected with the tractor head connecting piece through a horizontally-arranged first rotating shaft; one end of the first rotating shaft is fixedly connected with the middle connecting piece, a regular polygon prism is arranged at the other end of the first rotating shaft, a circular shaft is arranged in the middle end of the first rotating shaft and rotationally connected with the tractor head connecting piece, and the number of the prism edges of the regular polygon prism is even; a position-locking device is mounted on the tractor head connecting piece and comprises a position-fixing assembly and a locking mechanism; the position-fixing assembly comprises a pressing block, a guiding rod and a driving mechanism, wherein the front end of the guiding rod is connected with the pressing block, and the pressing block is used for applying pressure to the regular polygon prism of the first rotating shaft to set the middle connecting piece right, so that the middle connecting piece is parallel to the tractor head connecting piece. According to the disc-type tractor connecting buckle, the first rotating shaft can lose the rotating effect when needed, the degree of freedom during traveling on a level road is decreased, the traveling comfort degree is increased, and abrasion of the first rotating shaft isalso reduced.

Description

technical field [0001] The invention relates to a mechanical part of a disc tractor, in particular to a connecting buckle for a disc tractor with a locking function. Background technique [0002] At present, in addition to being equipped with corresponding agricultural machinery for farmland operations, tractors are also equipped with trailers for transportation operations. Generally, a disc tractor and a trailer need to be connected with a connecting buckle. The connecting buckle often has a rotating shaft to improve the trailer. The relative running dimension of the trailer can avoid rollover or tilting of the trailer with the front of the vehicle. At that time, on flat roads, there was no need for too many degrees of freedom between the disc tractor and the trailer. Too many degrees of freedom would affect the stability and comfort of driving on flat roads, and unnecessarily increased the rotating shaft. of rotational wear. Contents of the invention [0003] The prese...
