Description

Connecting traction structure of agricultural machinery Technical Field The utility model relates to a connect and pull structural technical field, especially relate to a connect and pull structure of agricultural machinery. Background In the working process of agricultural machinery, the tractor is generally pulled by the locomotive to carry out the operation, and the connection between locomotive and the trailer is realized connecting the installation through the bolt and is penetrated through the traction frame installed on locomotive and the trailer, but generally can be connected with the power connecting pipe between locomotive and the trailer and carry out power transmission, but the traction frame installed on locomotive and the trailer can't realize corresponding position spacing to the power connecting pipe now, leads to the working process, because of the random rocking of power connecting pipe position, causes the power connecting pipe to pinch off easily and damages, has the defect not enough. Disclosure of utility model The utility model relates to a connection traction structure of agricultural machinery has solved the unable corresponding position of realization of traction frame installed on present locomotive and the trailer to the power connecting pipe and spacing, leads to in the course of the work, because of the random rocking of power connecting pipe position, causes the problem of power connecting pipe pinch-off damage easily. The utility model provides a connection traction structure of agricultural machinery, specifically include the cooperation connection block, the cooperation connection block is square block structure, is equipped with a spacing annular block directly over the cooperation connection block, and spacing annular block periphery bottom center part is equipped with the extension block that is circular block structure, extension block bottom face axle center part fixed mounting has a spring connector, and spring connector bottom links to each other with cooperation connection block terminal surface welding, a joint opening that is linked together with its inner peripheral face is offered to spacing annular block periphery front side below, and the upper and lower both sides of joint opening are semi-circular structure.
