Abstract
The utility model relates to a hand tractor, which is characterized in that a primary and a secondary speed change mechanisms, a central transmission mechanism, a steering mechanism and a final transmission mechanism are all arranged in a transmission box; two gears arranged on two haft shafts of two driving wheels are respectively engaged with two gears arranged on the same speed reducing shaft. The transmission mechanisms of the utility model have the advantages of compactness, reasonableness, and improved strength intensity and rigidity and are suitable for the requirement of the transmission of high power. The utility model can be provided with a wide rotary tiller to carry out working for improving the working quality.
Description
The utility model relates to farm power machinery--the walker tractor of a kind of two-wheeled, single shaft driving.
East wind-12 type walker tractor is one of the widest walker tractor of present China production lot maximum, use.It is the S195 diesel engine of 8.8KW (12PS) that east wind-12 type walker tractor adopts power, driving engine is horizontal on frame, its power is passed toward driven pulley by three Type B V bands through driving pulley, driven pulley is the housing of power-transfer clutch, and power reaches change speed gear box by chain after by power-transfer clutch and is divided into two-way: leading up to variable gear, main gear, steering hardware, final transmission etc. reaches drive wheel; Another road passes colter transmission gearbox toward rotovator to coulter shaft from I reverse gearwheel or intermediate gear, and its speed-changing mechanism adopts composition formula, forms by major and minor speed-changing mechanism, gearbox body with about the main box of final transmission case body composition driving system.
The working width of rotovator is determined according to factors such as trac. watt level and unit speed of advances.Because consumption of power is bigger during rotovator work, therefore, east wind-12 type walker tractor is when designing supporting rotovator, the working width of rotovator can only be 600mm, and (640mm) is also narrow than minimum wheelspan, and wheel is walked on ploughing, form very dark rut, influence farmland quality.
The purpose of this utility model promptly is to design a kind of high-power, high efficiency, high operation quality at the problems referred to above, walker tractor that can supporting wide cut outfitting tool.
The purpose of this utility model is realized by the following technical programs:
Feature of the present utility model is that major and minor speed-changing mechanism, central control mechanism, steering hardware and final drive gear all are located in the transmission gearbox, two gears on two drive wheel semiaxis respectively with same deboost axle on two gears mesh.
Driving pulley on the driving engine of walker tractor, be four groove belt pulleys as the driven pulley of clutch-bell cover.
The transmission gearbox back can articulate a rotovator colter is just changeing gear case, just changeing and establishing a duplex gear in the gear case, a gear mesh on intermediate gear in the transmission gearbox and the dual gear, another gear on the dual gear and the engagement of the colter transmission gear on the rotovator.
Transmission gearbox back or articulate a rotovator counter gear case, establish a intermediate gear in double crosslinking gear shaft, dual gear, middle axle of carrier pulley and middle idle wheel, the transmission gearbox and a gear mesh in the dual gear in the counter gear case, on the dual gear another gear and middle idle wheel engagement, the colter transmission gear on middle idle wheel and the rotovator meshes.
Technical characterstic of the present utility model and good effect:
1, the utility model all is located at the Transmission in original gearbox body and the left and right final transmission case body in the same casing, makes structure compact more, and intensity, rigidity are improved, thereby can dispose high-performance driving engine.
2, because configurable high-performance driving engine, thus can supporting wide cut work tool, as the wide cut rotovator, but and the high speed operation, operation quality improves greatly.
3, because transmission gearbox can articulate the forward or reverse gear case, strengthened the distance between transmission gearbox and the rotovator, carried out farming, made trac. can adapt to different edaphic condition so after the tire with trac. changes the outfit into anti sliding wheel, still can load onto rotovator.
4, after transmission gearbox articulates the counter gear case, strengthened the distance between transmission gearbox and the rotovator, the anti sliding wheel that not only can change the outfit, and can make colter counter-rotating stubble-cleaning.
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is done further narration:
Accompanying drawing 1 is the utility model driving system sketch, and 1 is diesel engine, the 2nd among the figure, belt, the 3rd, power-transfer clutch, the 4th, chain gear case, the 5th, transmission gearbox, the 6th, drive wheel, the 7th, rotovator.
Accompanying drawing 2 is that transmission gearbox articulates the scheme drawing that the rotovator colter is just changeing gear case, and 8 is intermediate gears, the 9th among the figure, gear case, the 10th, dual gear, the 11st, middle idle wheel, the 12nd, rotovator colter transmission gear.
Accompanying drawing 3 is scheme drawings that transmission gearbox articulates rotovator colter counter gear case, and 13 is intermediate gears, the 14th among the figure, gear case, the 15th, dual gear, the 16th, rotovator transmission gear.
As shown in Figure 1, the power of tooth oil machine 1 reaches power-transfer clutch 3 by four belts 2, reach gears at different levels in the transmission case body 5 through chain gear case 4, finally drive drive wheels 6 rotations by drive wheel semiaxis 17 and advance, the power of rotovator 7 is imported into by intermediate gear in the transmission gearbox 5 or reverse gearwheel.
Gearbox designs compactness, intensity, rigidity all improve greatly, adapt to driving system and pass high-performance requirement.
As shown in Figure 2, a gear mesh in the dual gear 10 in intermediate gear 8 and the gear case 9, another gear in the dual gear 10 and 11 engagements of the middle idle wheel in the gear case 9, middle idle wheel 11 and 12 engagements of rotovator colter transmission gear.Owing to be provided with and just change gear case 9, enlarged the spacing of transmission gearbox and rotovator, the rubber tire of the trac. nonskid tire that can change the outfit.
As shown in Figure 3, a gear mesh in the dual gear 15 in intermediate gear 13 and the gear case 14, another gear in the dual gear 15 and 16 engagements of the colter transmission gear on the rotovator.So not only interchangeable anti sliding wheel but also can make coulter shaft counter-rotating, stubble-cleaning.
