Description

Technical Field

[0001] The invention relates to a harvester with a hydraulic travel system, belonging to the technical field of corn harvesters. Background Art

[0002] The existing corn harvester generally picks corn ears by a cutting platform arranged at the front end of the vehicle body, and then returns the stalks to the field by a field return machine located at the bottom of the vehicle body. The cutting platform is connected to the engine through a transmission system, and the cutting platform is driven by the engine to work.

[0003] For example, the existing patent 202021838447.3 discloses a new type of corn harvester header with double-sided transmission, in which the two ends of the middle rotating shaft of the header respectively drive the assembly of the upper left middle transmission shaft and the upper right middle transmission shaft, and the upper left middle transmission shaft and the upper right middle transmission shaft are respectively connected to the left and right straw choppers through double-row chains, and the upper left middle transmission shaft and the upper right middle transmission shaft respectively drive the lower left middle transmission shaft and the lower right middle transmission shaft through double-row chains, and the lower left middle transmission shaft and the lower right middle transmission shaft are used to connect four ear picking units, two small elevators and two auger combinations; it solves the problems in the prior art that the transmission chain of the corn harvester header is easy to heat up and break, the transmission shaft is easy to bend, and the reliability of the header transmission is not high, so that the transmission layout of the header is more reasonable, the load distribution is uniform, the operation is smooth, and the reliability is improved; it realizes double-sided transmission on both sides of the header, and the transmission components are symmetrically arranged, the parts have high versatility, and maintenance is very convenient. However, the transmission system of the harvester's header is complex, with many transmission stages and low transmission efficiency. It can only harvest ears but not straw. When harvesting corn, an additional straw harvester is still needed to cut the straw. It is not practical. Moreover, the corn stalks are directly crushed by the field returner installed at the bottom of the vehicle body. Since the corn stalks are still growing on the ground, it is inevitable that the straw will be missed and cannot be completely crushed by the field returner, which reduces the field return quality of the field returner.

[0004] For example, the existing patent 201620356184.X discloses a dual-power transmission device for a small corn harvester, including a gearbox, an engine and a transmission shaft, the gearbox includes a travel gearbox and a front transmission gearbox, the engine has a front travel output wheel and a rear power output wheel, the front travel output wheel is connected to the travel gearbox output pulley through a transmission belt, and the rear power output wheel is connected to the front transmission gearbox output pulley through a transmission belt, so as to achieve a uniform distribution of the transmission force of the small corn harvester and reduce the failure rate of the belt and the engine. However, it still adopts the traditional mechanical transmission structure, has high requirements on the installation position and direction of the engine, and needs to set up a large number of power transmission structures, resulting in a more complex overall spatial structure, large space occupation, and also affecting the arrangement and installation of devices such as peeling machines and field return machines on the harvester.

[0005] Therefore, how to provide a harvester with a simple driving structure and high transmission efficiency of the harvesting table is one of the technical difficulties that urgently needs to be solved. Summary of the invention

[0006] In view of the above-mentioned prior art, the purpose of the present invention is to provide a harvester with a hydraulic travel system. The harvester adopts a hydraulic travel system, which avoids the need to set up a large number of transmission structures such as transmission shafts for power transmission. The engine installation position is flexible, and the pipeline is better adapted to the complex spatial structure of the harvester, thereby optimizing the structure of the harvester. In addition, the transmission structure of the harvesting platform is optimized, the number of transmission levels is reduced, and the transmission efficiency is improved. In addition, a straw cutting roller is provided under the harvesting platform to cut the corn stalks in advance, and then the corn stalks are crushed and returned to the field under the action of the field return machine at the lower end of the vehicle body, thereby improving the practicality and field return quality of the harvester.

In addition, the harvester uses a hydraulic travel system to drive, avoiding the space limitation of mechanical transmission. The hydraulic pipeline routing is flexible, and there is no need to set up a large number of transmission shafts for power transmission. The space occupancy is small, and the position and direction of the engine are not restricted, which better adapts to the complex spatial structure of the harvester. The radiator is staggered with the engine to avoid the radiator being affected by the high temperature of the engine. The size of the radiator is not restricted, which can achieve higher heat dissipation efficiency, prevent the hydraulic oil temperature from being too high, and ensure the stability of the hydraulic travel system.
