Abstract

The utility model provides a technical scheme of a cutter shaft hydraulic driving device of a mixing machine or a rotary cultivator. The technological scheme features that a gear box is installed on the cutter head of blender or the rotary cutter casing of rotary cultivator, the input driving shaft of the gear box is connected to the output shaft of tractor, the output shaft of the gear box is connected to a hydraulic pump, the output oil pipe of the hydraulic pump is connected via regulating valve to a hydraulic motor, the output shaft of the hydraulic motor is connected to the cutter shaft of the blender or rotary cultivator, and the casing has also oil tank with oil pipe connected to the hydraulic pump and the hydraulic motor.

Description

The cutter shaft fluid pressure drive device of mixer or rotovator

The utility model relates to a kind of fluid pressure drive device, especially the cutter shaft fluid pressure drive device of mixer or rotovator.

No. 95234354.1 open by Patent Office of the People's Republic of China and authorize patents, a kind of technical scheme of highway soil stabilizer is disclosed, the driving of cutter shaft is the power that gives by tractor in this scheme, driving the reduction box of being made up of gear through power transmission shaft again slows down power, the output shaft of reduction box then removes to drive cutter shaft and rotates, therefore, the driving of cutter shaft is by machine driving fully, this mechanically operated shortcoming is when the resistance of cutter shaft is excessive, will damage reduction box, power transmission shaft or the driving shaft that is connected with tractor cause the damage of entire machine, and this scheme can only make the cutter shaft folk prescription to rotation, can not realize two-way rotation.

The purpose of this utility model is exactly at the existing in prior technology shortcoming, and a kind of mixer of hydraulic technique driving cutter shaft or cutter shaft fluid pressure drive device technical scheme that rotovator is used of adopting is provided.

For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, the technical characterictic of this programme is described in detail.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment.

By in the accompanying drawing as can be seen, the cutter shaft fluid pressure drive device of mixer of this programme or rotovator, be one gearbox 5 to be housed on the cutter case 7 the cutterhead or the revolving of rotovator of mixer, the input drive shaft 4 of gearbox 5 is connected with the output shaft of tractor, the output shaft 8 of gearbox 5 connects a hydraulic pump 3, the output oil pipe of hydraulic pump 3 connects hydraulic motor 1 through control valve 2, the output shaft of hydraulic motor 1 connects the cutter shaft 11 of mixer or rotovator, on case 7, also have fuel tank 10 in addition, have oil pipe to be connected with hydraulic motor 1 on it with hydraulic pump 3.Described gearbox 5, its the simplest structure is that driving shaft 4 connects a big driven wheel 6, driven wheel 6 and little output gear 9 engagements, the output shaft 8 of 9 connection gearboxes 5 of output gear, so just tractor can be defeated by the low speed of driving shaft 4, become the high speed of gearbox 5 output shafts 8 outputs.Certainly, gearbox 5 adopts other version also can reach same effect.

In this programme, because the existence of gearbox is arranged, the power that tractor can be transported raises speed, then, export to hydraulic pump, make hydraulic pump have high speed power, hydraulic pump makes the hydraulic oil of exporting after the hydraulic oil supercharging, transfer to hydraulic motor through control valve, hydraulic motor rotates under the driving of hydraulic oil, and is subjected to the control of control valve can realize the forward and backward of hydraulic motor.This shows, in this programme, removed the mechanically operated cutter shaft driving mechanism that mixer or rotovator are easy to damage, and can realize that cutter shaft has the forward and backward function, as seen compared with prior art, have substantive distinguishing features and progress, its implementation result also is conspicuous.
