Background
The corn harvester is an agricultural device for harvesting and accumulating corn ears and straws. Most of the corn harvester travel systems adopt traditional mechanical transmission. Corn harvester is commonly provided with numerous mechanisms such as fruit cluster header, straw header, lift conveyer, peeler, hacking machine, grass case and grain case, adopts mechanical transmission's corn harvester, and mechanical transmission system volume is big, and its drive part is more, and each drive part needs to avoid above-mentioned each functional mechanism, leads to mechanical transmission system to need set up more grades just can transmit to the walking wheel, and the structure is more complicated, and transmission efficiency is low.
The existing hydraulic walking system can not provide excessive torque for the motor vehicle, and the corn harvester just does not need excessive driving torque when walking. Therefore, to avoid the use of complex mechanical traveling systems, some corn harvesters use hydraulic traveling systems. For example, the existing patent ZL201822181440.8 discloses a hydrostatic walking driving system suitable for a corn harvester with both ears and stems, which is directly connected with a gearbox by arranging a quantitative motor, so that a stepless speed change wheel and a clutch are eliminated, and the walking fault is reduced. The control of the opening degree and the direction of the variable pump is realized by controlling the steering oil cylinder through the electric displacement control valve, so that the control of the speed and the direction of the quantitative motor is controlled. But this patent still needs to set up mechanical type braking system alone and brakes, and the structure is complicated and the reliability is lower, and the high-pressure oil pipe of control oil circuit directly comes from the variable pump, and its pressure can not accurate control, and discharge capacity control valve needs higher quality fluid moreover, and the fluid journal in the variable pump is higher, leads to controlling the oil circuit jam easily.
In addition, the transmission system of the straw cutting table and the straw feeding device of the existing corn harvester has the advantages of complex structure, more transmission stages and low transmission efficiency. Moreover, the cutting guide of the straw cutting table and the feeding effect of the straw feeding device are not ideal, so that the straw is easy to miss-cut, for example, the existing patent ZL201310064490.7 discloses a small and medium-sized self-propelled combine harvester for harvesting corn with both ears, and the straw feeding auger adopts a common auger structure, so that the cut straw cannot be accurately guided to the straw feeding device. Secondly, the straw feeding device adopts a front feeding roller, a middle feeding roller and a rear feeding roller which are positioned at the same layer, and the feeding device in the structure has poor feeding effect and part of inaccurate straw can not be normally fed into the hay cutter. Secondly, the feeding speed is low by adopting a row arrangement mode, and the harvesting efficiency is reduced.
Therefore, the hydraulic traveling system with high reliability and the corn harvester with high cutting guiding and feeding efficiency and good quality are provided in time, and the hydraulic traveling system has very important significance.
