Abstract
The utility model relates to a double-crawler type miniature hand tractor. A diesel internal combustion engine is arranged in front upper part of a machine frame, a plow share is arranged in front lower part, a handrail and a variable speed transmission box are arranged in back upper part, a disc harrow is arranged in back lower part, and a crawler mechanism is arranged at just lower part. The utility model is superior to common tractors and single-crawler tillers, the stable equilibrium performance of the double-crawler is good, climbing ability is strong, and turning radius is small. The utility model not only can be used in flat area, but also be suitable for the farming in mountain areas, semi-mountain areas, small fields and terraces, and the utility model has multiple functions. Therefore, the utility model can be used as the power of small harvesters and other agricultural machines so as to accomplish agricultural mechanization in mountain areas and semi-mountain areas.
Description
The utility model belongs to agricultural machinery.
How common walker tractor finishes with the rolling of rubber wheel if travelling, because the rotation of wheel is advanced, grade climbing performance is relatively poor, and wheelspan is wide, can not travel on narrow and small road surface or ridge, and Turning radius is bigger.The tiller balance quality of the mono-track that has improved is relatively poor, strap speed varying, and the power transport is low, and transmission stability is poor, and power consumption is bigger slowly and again for ploughing speed.
According to above-mentioned situation, the purpose of this utility model is a kind of double-crawler type miniature walking tractor of design.
The purpose of this utility model is achieved in that colter is equipped with in the front lower place at the front upper place of frame device diesel engine, and transfer gear box is equipped with in the back upper place, speed-changing mechanism and transmission device collection are loaded in the case, handrail also is equipped with in the back upper place, and disc harrow is equipped with in the back lower place, under two crawler belts are housed.
Because said structure, the utility model adopts two crawler belts, the balance of travelling, grade climbing performance is good, can conveniently cross the raised path through fields and ditch in the operation, and can travel on narrow and small road surface or ridge, Turning radius is little, adopt gear, the transmission of chain speed change, transmission performance is good and stable, power transport height, and ploughing speed is fast and energy-conservation.It not only can be used for the region of no relief farming, more is applicable to the farming of mountain area, upper level small size field piece and terraced fields, can be used as the power of small harvester and other field machine again.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1, be the utility model overall schematic;
Fig. 2, be the utility model change gearbox structural scheme of mechanism;
Fig. 3, be the utility model pedrail mechanism scheme drawing.
In conjunction with Fig. 1, (1) is frame of the present utility model, diesel engine (2) device between 3 kilowatts to 6 kilowatts of the rating horsepowers is in the front upper place of machine (1), colter (8) is equipped with in the front lower place, the device of frame (1) back upper place, be that collection dress speed-changing mechanism and transmission device are change gearbox (3), the handrail (7) of one, disc harrow (9) is equipped with in the back lower place, under pedrail mechanism (4) is housed.
In conjunction with Fig. 2, driving gear (10) and intermediate gear (11), engage a gear gear (12), intermediate gear (14), transmission gear (15) coincide respectively and constitute the speed change D Drive, hang up reverse gearwheel (12) and constitute reverse gear.Transmission drive sprocket (16), messenger chain (17) and driven sprocket (18) are formed transmission device jointly.
In conjunction with Fig. 3, roll in chain crawler belt (6) and form pedrail mechanism (4) by cterpillar drive wheel (5), two band pawls.
When starting diesel engine, hang up D Drive, the driving gear (10) that rotates drives intermediate gear (11), (14), engage a gear gear (13), transmission gear (15) rotates, transmission gear (15) and transmission drive sprocket (16) are coaxial fixing, transmission drive sprocket (16) rotates and by messenger chain (17) thereupon, band changes driven sprocket (18), because driven sprocket (18) is coaxial fixing with Athey wheel (5), institute makes trac. to overtake so that Athey wheel (5) rotates thereby band changes crawler belt (6), the colter farming, disc harrow (9) is broken the upturned soil block rake of plough.If hang up reverse gearwheel (12), trac. can travel backward.
Above-mentioned two warm belt miniature walking tractor, manufactured materials is easily purchased, low cost of manufacture, general miniature farm machinery factory can both implement the utility model.
Because characteristics of the present utility model are highly suitable for mountain area, the popularization of upper level rural area, to accelerating mountain area upper level mechanization of agriculture promotional value are arranged.
Claims (2)
1, a kind of double-crawler type miniature walking tractor, by frame (1), diesel engine (2), change gearbox (3), pedrail mechanism (4) is formed, and it is characterized in that:
Collection dress speed-changing mechanism and transmission device in a, the described change gearbox (3);
B, described pedrail mechanism (4) are made of Athey wheel (5) and two band pawl roller chain crawler belts (6);
C, described diesel engine rating horsepower are between 3 kilowatts to 6 kilowatts;
D, described frame (1) front upper place device diesel engine (2), colter (8) is equipped with in the front lower place, back upper place device change gearbox (3), handrail (7), disc harrow (9) is equipped with in the back lower place, under pedrail mechanism (4) is housed.
2, double-crawler type miniature walking tractor according to claim 1, it is characterized in that: by driving gear (10), intermediate gear (11), engage a gear gear (13), intermediate gear (14), transmission gear (15), coincide to constitute the speed change D Drive respectively, hang up reverse gearwheel (12) and constitute reverse gear, by speed change, advance, reverse gear forms speed-changing mechanism, by transmission drive sprocket (16), messenger chain (17) and driven sprocket (18) are formed transmission device jointly.
