Description

Technical Field

[0001] The utility model relates to the technical field of four-wheel drive micro-tillage machines, in particular to a vertical transmission four-wheel drive micro-tillage machine. Background Art

[0002] The four-wheel drive tillage machine is a kind of agricultural machinery equipment used for tilling farmland. Its characteristic is that it uses four driving wheels to complete the traction or driving working mode. It has a wide range of applications in agricultural production, such as dry land, paddy fields, orchards in plains, mountainous areas and hills. It can complete operations such as pumping water, generating electricity, spraying pesticides, and spraying, and tow trailers for short-distance transportation. The four-wheel drive tillage machine has become an important tool for farmers to farm with its high efficiency, stability and adaptability.

[0003] As disclosed in a Chinese patent: A direct-connected four-wheel drive micro-tillage machine, application number: CN202323107019.X, including a power unit module, a flange is fixedly installed at the output end face of the power unit module, a gearbox assembly is fixedly installed on the side of the flange away from the power unit module, an armrest control system is fixedly installed on the upper end face of the gearbox assembly away from the flange, and a transfer flange is fixedly installed on the lower end face of the gearbox assembly. For this direct-connected four-wheel drive micro-tillage machine, regardless of the gear position of the shift mechanism on the gearbox assembly, the tillage shift mechanism and the travel shift mechanism in the travel tillage box assembly can be placed in neutral to stop the tillage output and travel output. During the operation process, the operator selects different output speeds by operating the change mechanism and the travel shift mechanism according to the actual use situation. Left or right turns are achieved by operating the travel steering mechanism.

[0004] However, in the above technical scheme, the transmission part of the current four-wheel drive micro-tillage machine mostly adopts a single clutch plate structure. Since the clutch plate needs to be frequently engaged and disengaged, it is subjected to large torque and wear, and is therefore prone to failure. In addition, during the transmission process, due to the friction loss of the clutch plate and the resistance of other components, part of the power will be consumed and cannot be fully transmitted to the output shaft, resulting in low efficiency and large power loss. In addition, when cultivating areas that require high-precision cultivation, it is necessary to increase the reduction ratio to provide a more stable cultivation effect and reduce errors. However, the current four-wheel drive micro-tillage machine cannot change the reduction ratio accordingly according to the use requirements. Utility Model Content
