Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pumps, in particular to a harvester hydraulic pump. Background Art

[0002] A harvester is an integrated machine for harvesting crops. It completes harvesting and threshing at one time, and concentrates the grains in storage bins, and then transports the grains to transport vehicles via conveyor belts.

[0003] Among the various components of the harvester, the hydraulic pump is a hydraulic system power component that is driven by an engine or an electric motor and converts mechanical energy into hydraulic energy. It generally sucks oil from the hydraulic oil tank and transports it into the pump body to bring about a change in the volume of the pump chamber, thereby compressing the fluid so that the fluid has pressure energy and helps complete the mechanical movement.

[0004] The existing harvester hydraulic pump connects the equipment through the hydraulic rod at the output end to drive the equipment. The output end of the hydraulic pump is generally a rod body with a fixed shape and connection point. In actual use, it cannot adapt to different connection devices, which limits the use of the hydraulic pump. For this reason, we propose a harvester hydraulic pump. Utility Model Content
