Problems solved by technology

[0003] However, in the above-mentioned prior art, since the clutch is provided at the front portion of the hydrostatic continuously variable transmission, when the clutch is a wet multi-plate clutch with good durability, a clutch case with a built-in clutch other than the gearbox is required. Complicated the structure and increased the cost

Embodiment Construction

[0035] Hereinafter, the description of the present invention will be made with reference to the accompanying drawings showing a rice transplanter as an example of a paddy field operation machine.

[0036] Examples will be described.

[0037] As shown in Figure 1 and Figure 2, this rice transplanter has a left and right pair of driving front wheels (equivalent to front wheels) 1 and a left and right pair of driving rear wheels (equivalent to rear wheels) 2. The rear part of the planting device 4 is connected with a multi-row planting type planting device 4 as an example of a paddy field operation device through a four-bar linkage 5. It is also provided with a lifting hydraulic cylinder 6 and a fertilizing device that utilizes an oil cylinder to lift the planting device 4. 7.

[0038] self-propelled body 3 as image 3 , Figure 4 As shown, there is a gearbox 9 that drives the front wheels 1 through the front axle box 8. At the same time, in the body frame that drives the rear ...

Abstract

The invention relates to a paddy field operation machine, wherein an operation unit is connected with the rear part of the self-moving body with a gearbox and a shaft bearing front wheel. The operation machine is characterized in that, the steering device of the paddy field operation machine comprises a power-assisted moment generator for oil pressure steering connected with the upper surface of the gearbox and a link arm interlinked with the front wheel; a vertical revolving axle interlinked with the output shaft of the moment generator is arranged in the gearbox; the prominent link arm shaft of the link arm is arranged at the lower part of the gearbox; in order to connect the moment generator and the link arm by the vertical revolving axle, the vertical revolving axle is arranged to extend in coaxial status with the link arm; a reducing transmission mechanism is also arranged to reducing transfer an operation force from the vertical revolving axle to the link arm shaft; the reducing transmission mechanism is a gear reduction mechanism. The operation machine has the advantages that, the first drive gear arranged at the lower part of the vertical revolving axle is meshed and interlinked the first driven gear arranged in parallel with the central transmission shaft of the vertical revolving axle; a second drive gear arranged at the lower pat of the central transmission shaft is meshed and interlinked with a second driven gear arranged on the link arm shaft; then reduced transmission is realized.

Description

technical field [0001] The invention relates to a paddy field operation machine such as a rice transplanter equipped with a clutch, a hydrostatic stepless transmission device and a gearbox, and in particular relates to a technology with a simple car body structure and good operability. Background technique [0002] In the past, the transmission device of the paddy field working machine is disclosed in the Japanese Patent Application Publication No. 10-54461, which is equipped with a clutch for connecting and disconnecting the engine power and a hydrostatic continuously variable transmission device that receives the output of the clutch. The output of the continuously variable transmission is transmitted to the transmission body. [0003] However, in the above-mentioned prior art, since the clutch is provided at the front portion of the hydrostatic continuously variable transmission, when the clutch is a wet multi-plate clutch with good durability, a clutch case with a built-...
