Hydraulic generating device and agricultural machine with same

Abstract

The invention discloses a hydraulic generating device and an agricultural machine with the same. The hydraulic generating device comprises a gear pump which is positioned outside an engine of the agricultural machine, and a main shaft of the gear pump is connected with a power output end of the engine through a transmission mechanism. The hydraulic generating device disclosed the invention is applied on the agricultural machine, the gear pump is arranged outside the engine, and the engine is used for supplying driving force to the gear pump, so that the assemble space of the gear pump is enlarged, and the failure rate of the gear pump is reduced; the assembling labor and the assembling time for a workshop are reduced, and the maintenance is convenient and fast; besides, a pressure spring sleeves a connecting rod to form a tension mechanism, so that the pressure spring on the connecting rod is not easy to fall down, and reliable adjustment of the tension is ensured.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular, the invention relates to a hydraulic pressure generating device and an agricultural machinery with the same. Background technique [0002] The purpose of setting the gear pump on the existing agricultural machinery, such as the corn machine, is to generate the hydraulic oil pressure required by the hydraulic system. Specifically, the power of the engine is used to transmit it to the gear pump, which is converted into hydraulic oil pressure by the gear pump, and then used The pressure of the oil circuit promotes the expansion and contraction of the oil cylinder, so as to realize the steering of the corn machine, the lifting of the grain tank, and the lifting of the working parts such as the header and the field returning machine. [0003] Since the work of the gear pump needs to be powered by the engine, the transmission power generally uses the form of gear meshing. ...

Problems solved by technology

Moreover, the gear pump is installed in the engine casing. Because the working environment of the corn machine is relatively harsh, a ridge is generally formed in the corn field to facilitate the irrigation of the corn. This kind of ridge has a great influence on the steering of the corn machine. If the ground is sunken in the ridge, if the direction is too large, it will easily cause the continuous high temperature of the gear pump and damage the gear pump. On other working devices of the corn machine, the lifting of the header, the lifting of the returning machine, and the grain Lifting and lowering of the gear box, etc., if the phenomenon of stagnation occurs, it will also cause high temperature of the gear pump, which will cause the gear pump to hit teeth or leak oil; due to the small assembly space of the gear pump, it is difficult to assemble, once the gear is damaged, it is inconvenient to maintain , the replacement is labor-intensive and time-consuming
