Description

Tractor

Technical field

The present invention relates to manufacture of agricultural machinery technical field, especially a kind of tractor.

Background technology

Tractor refers to for drawing, promote, carry or drive outfitting tool to carry out the self-propelled motor machinery of operation, it is that peasant is engaged in Economic development and the main tool of agro-farming operation, a kind of wheeled tractor as shown in Figure 5, Figure 6, include propons, back axle and engine 102, engine 102 is connected with rear axle box 101 by wheel box, and rear axle box 101 is provided with the spline output shaft 103 that the walking power output shaft being connected with rear walking wheel drive unit is connected and the lifting pull bar device 104 being contained in rear axle box driven by lifting drive output shaft with farm implements. In use there is following deficiency in this kind of tractor: 1, the Power output of engine is to rear axle box, the trailing wheel walking of tractor is driven by walking power output shaft, pass through spline output shaft by power transmission to farm implements simultaneously, because the output torque by rear axle box structural limitations spline output shaft is little, power is weak, farm implements once can only be driven to carry out a kind of operation, it is necessary to change farm implements and just can carry out lower step operation, can not integration of operation, working efficiency is low; 2, farm implements lifting and descend through lifting drive output shaft drive promote pull bar device realize, and lifting drive output shaft is one of three power output shaft of rear axle box, therefore often cause because the output torque of lifting drive output shaft is little tractor lifting pull bar device action slowly and sensitivity low.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of tractor with integration of operation function, and it is little that this kind of tractor can solve existing tractor output torque, and function singleness, causes the problem of operation inefficiency.

In order to solve the problem, the technical solution adopted in the present invention is: this kind of tractor, comprise propons, back axle and lifting pull bar device, described propons and back axle are provided with vehicle frame, the front end of described vehicle frame is hinged with and promotes arm by many of the first hydraulic ram lifting, described lifting arm is connected with and cuts leaf device; Described leaf device of cutting comprises bracing frame, the cutter shaft rotated by the first fluid motor-driven, and interval is arranged on the much knives tool on described cutter shaft; The bridge case being in transmission connection by front power input shaft and engine is equipped with in the rear end of described vehicle frame; Described bridge case is hinged with the 2nd hydraulic ram driving described lifting pull bar device lifting; Described lifting pull bar device is connected with farming support, described farming support is disposed with deep soil loosing shovel, scrapes mamoty, boot and by the 2nd fluid motor-driven rotate rotary-blade; Described first hydraulic ram, the first oil motor, the 2nd hydraulic ram and the 2nd oil motor are connected with hydro-pump respectively, and described hydro-pump is connected with engine by transfer gear.

In technique scheme, technical scheme can also be more specifically: is connected with strong beam between described lifting arm, described first hydraulic ram be contained in that the front end with vehicle frame is fixedly connected with between a suspension permanent seat and described lifting arm, support frame as described above comprises crossbeam, described crossbeam is fixed with three Connection Blocks equidistantly arranged, described cutter shaft and three described Connection Blocks are hinged, and have two the first hydraulic rams, and described first hydraulic ram sets up separately in the both sides being positioned at middle described Connection Block; Described crossbeam is fixed with just to two montants, montant described in every root is all hinged with two described lifting arms, between two described lifting arms of top, it is connected with two described strong beams, it is positioned at and is connected by bending bar respectively with the two ends of described crossbeam outside two lifting arms of lower section; Described hydro-pump is toothed gear pump, and the input terminus of described toothed gear pump is in transmission connection by the engine output terminal of transfer gear and described tractor.

Further: described lifting pull bar device comprises the lifting rod being hinged on described bridge case and by the hinged push rod of pull bar and described lifting rod, described 2nd hydro-cylinder is contained between described bridge case and described push rod.

Further: at described farming frame upper, fertilizer storage box being housed, described fertilizer storage box is provided with to be stretched respectively to the soil inlet pipe between described deep soil loosing shovel and described rotary-blade and the plantation inlet pipe stretched to described boot rear.

Owing to have employed technique scheme, the present invention compared with prior art has following useful effect:

1, owing to being provided with vehicle frame on propons and back axle, the bridge case being in transmission connection by front power input shaft and engine is housed in the rear end of vehicle frame, the power of tractor walking separates transmission to the power of input bridge case with driving, not only the moment of torsion of the power output shaft of bridge case is big, powerful also add tractor overall construction intensity, complete machine is not easily damaged, extends work-ing life.

2, driven by the first hydraulic ram owing to being arranged at the lifting arm of vehicle frame front end, cut cutter shaft that leaf device has by the first fluid motor-driven, and the lifting pull bar device being arranged at vehicle frame rear end is driven by the 2nd hydraulic ram, it is connected to the rotary-blade promoted on pull bar device by the 2nd fluid motor-driven; Owing to adopting hydraulic pressure transfer power, expand the variation range of the torque and rotational speed of Power output, to adapt to different operating modes, make engine work under preferably operating mode simultaneously; Fluid motor-driven, it may be achieved speed change, change square, interruption transmission of power, outputting power is strong, when Driven by Hydraulic Cylinder interrupts transmission of power, can make cutter shaft and rotary-blade stopping work, and whole car can be made like this not affected in road driving, temporary shut down and field adjustment.

3, cutting leaf device owing to vehicle frame front end is provided with, rear end is provided with deep soil loosing shovel, rotary-blade, scrapes mamoty and boot; When carrying out tractor-ploughing operation, the Caulis Sacchari sinensis leaf cutting leaf device cut-out field can be set before being arranged on tractor, the deep soil loosing shovel drawn by tractor rear end again, rotary-blade, scrape mamoty and deep ploughed in field by boot, rotary tillage, smooth, start and apply fertilizer, not only decrease the obstruction of Caulis Sacchari sinensis leaf or it is wound around agricultural machinery and implement, make broken soil, Caulis Sacchari sinensis leaf also Tian Gengjia, and disposable complete deep ploughing, rotary tillage, smooth, start and operation of applying fertilizer; Achieve the integration of operation in farmland, the manipulation number of times back and forth when simplifying tractor-ploughing, it is to increase operation efficiency, further mitigate the fatigue strength of officer.

4, the structure of bracing frame and lifting arm then improves the stability cutting leaf device.

5, due to inlet pipe that the top of farming support is provided with fertilizer storage box and is connected with fertilizer storage box, it may be achieved fertilising at once after deep ploughing, and by the rotary tillage carried out subsequently, fertilizer and soil are fully stirred, it is to increase fertilising efficiency.
