Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural machinery technology, in particular to a hydraulic pump connector.

[0002] When the tractor is used with other agricultural tools, it often needs to use the power provided by the external hydraulic pump. The way of connecting the hydraulic pump with the tractor is often to fix the hydraulic pump on the bracket, connect the bracket with the tractor, and connect the hydraulic pump with the rear output shaft of the tractor through the universal joint transmission shaft. The power output by the rear output shaft of the tractor drives the hydraulic pump to provide hydraulic power. This method has the disadvantages of large volume, complex installation and high cost. SUMMARY

[0003] In order to solve the above problems, the present application provides a hydraulic pump connector, which comprises a shaft connecting sleeve, a shaft fixing pin, a fixed arm, a fixed hole, a fixed sleeve, a connecting hole and a bearing. The shaft fixing pin is inserted into the shaft connecting sleeve. The shaft connecting sleeve is rotatably connected to the fixed sleeve through the bearing. One end of the fixed sleeve has a connecting hole. The fixed arm is fixedly connected to the fixed sleeve. The fixed arm has a fixed hole.

[0004] This device has the advantages of small volume, convenient installation and low cost. BRIEF DESCRIPTION OF DRAWINGS
