Abstract

A multifunctional walking tractor is composed of gear-shifting box, engine, frame, steering mechanism and clutch. The gear-shifting box and two drive casings are individually manufactured. A splined shaft sleeve for outputting power is used to conveniently exchange between single and double drive shafts. A single wheel can be installed in a space (350X15) between gear-shifting box and casings for transportation or other jobs. Caterpillar track can also be installed to it. It can operate for different agricultural jobs.

Description

Multifunctional walking-tractor

Scientific development along with mechanization of agriculture, make people pay attention to the status of field machine more, current many advanced persons' machinery is come out one after another, comprising small-sized two-wheel trac., one-wheeled tractor, cultivator, crawler belt Miniature cultivator used on higher etc., but above several vehicle function and usage are more single, generally only have a kind of radical function, relate to multi-functional machinery in addition still in the development phase, remain the improvement of further taping the latent power, and also lack the multi-functional mechanical that is applicable to agricultural production on the market.

The objective of the invention is: improve the weak point of above existing vehicle, a kind of multifunctional walking-tractor is provided.Do power with diesel engine, by change, the shape of change speed gear box, just, and single dual drive wheel mode, the purpose of realization farmland operation complete mechanicalization, and effect is good easy to use.

The object of the present invention is achieved like this:

It is made up of a kind of multifunctional walking-tractor air-cooled water-cooled diesel engine of 170-180 and variable speed drive (VSD) parts.Its major part has driving engine, and functional components such as arm-rest frame, steering hardware, power-transfer clutch, change speed gear box, drive wheel are formed.

Functional component one: gear box casing, bearing hole, drain oil, inspection, mounting hole, speed change, turn to, the backward gear mounting hole forms.

Functional component two: drive in the walking housing three transmission gears are housed, can make two kinds of housings of height as required, to change apart from floor level.

Functional component three: finally drive spline gear, this gear both ends of the surface are longer than other gear, for two side bearings and oil sealing, oil seal cover usefulness are installed, are shaped on splined hole in the middle of the outstanding drive shell of both ends of the surface outer (0.5 millimeter), are used to install axle drive shaft.

Four, two axle drive shafts of functional component, one is shaped on screw thread, spline for changing usefulness at any time, and other has a short spline axle drive shaft, uses for single-wheel.

Functional component five, single rubber wheel (400-8) track sprocket, support wheel, crawler belt, notes (crawler belt is not drawn component diagram separately, has only drawn a crawler vehicle scheme drawing).

The present invention has following functions peculiar.

Use same chassis, can install respectively, single two-wheel and crawler belt carry out farm work and transportation.

1, this change speed gear box drive part, for both sides separate, than other overall height in ground the general trac. of (500) millimeter apart from ground height (175-200) millimeter only.

2, Ben Che can install according to actual needs and drive two-wheel, single wheel, reach crawler belt, can carry out the floods and droughts field and plough, rakes the soil level and transport.

3, the both sides live axle unloaded, single driven wheel be installed, can also can be transported and easy to use in the field normal operation of high section crop at middle empty place.

4, crawler belt is installed and is carried out farm work, also can join small-sized dozer, level land, snow pushing, grain etc.

Multifunction walking machine drawing of the present invention, form,, constitute the trac. (seeing figure) of certain function with following functional component comprising a change speed gear box 10 by driving engine 13 and multifunctional chassis.

Functional component one change speed gear box 1, spline shaft drive gear 2 (this gear is structure as a whole with propeller shaft sleeve, also can the combination of two bodies), bearing 3, oil sealing 4, oil seal cover 5, screw 6, packing ring 7, nut 8, bearing 9, oil sealing 10, oil seal cover 11 are formed, and the propeller shaft sleeve endoporus is a splined hole, sees erection plan 2; Its two ends have bearing (bearing stand) to use for the bearing oil seal cover is installed.The outstanding change speed gear box outsides, its two ends (0.5) millimeter is in case the conversion axle drive shaft behind the fastening nut, rubs mutually with housing.Axle drive shaft 12 is made with ordinary steel, and an end has the Dan Pingjian groove, and an end is shaped on spline spiral shell strand insurance pin-and-hole, can will have spline during use, and an end inserts in the hub splines, installs the pad fastening nut, locks safety plug and gets final product.

Figure (1) single-wheel is made the spline axis with axle drive shaft, whole axle in the grid, during single wheel drive, is installed on and drives in the hub splines two ends installation door 3.

Fig. 2 in the grid, pad can be made with general iron, after installing for single driven wheel; Prevent live axle to string employ, and can be according to the gap needs, the levelling number, 3 grades of lids in the grid, four jiaos respectively are drilled with screw, are fixed in outside the drive shell oil seal cover, prevent that the castellated shaft string from going out.

4 drive wheels in the grid, it by 6 layer lines and rubber make cover tire, the inner tube of a tyre is made with rubber, steel plate is made two bodies with the skin steel, and circular the hole, garden is left in the centre with six sieve silk secure bond, for hub splines usefulness is installed, hub splines, available notes steel are made with 4 screws and are fixed on the steel plate.

More than several parts can be according to practical application at the iron drive wheel that guarantees to make under the situation of safety factor other different shape etc.

Also can change air-cooled liquid-cooled engine as required, also can select for use during two-wheeled work, now the rubber drive wheels of market general-duty (500-10).

When the present invention is two side drives, single-wheel use because of change speed gear box, the center of gravity unanimity, the axle drive shaft both sides are stressed firmer than existing single wheel cycle, and easy to use, during crawler belt work, Yin Benche can use the 180-170 diesel engine, the big crawler belt of horsepower is wide, goes out to possess the outer usefulness of can bulldozing of Miniature cultivator used on higher function.

Fig. 1 is the two-wheel lateral plan of invention, and Fig. 2 two-wheel birds-eye view, Fig. 3 single-wheel lateral plan, Fig. 4 single-wheel birds-eye view, Fig. 5 list two-wheel conversion erection plan, Fig. 6 crawler vehicle lateral plan, Fig. 7 change speed gear box are use up cun a figure and a shape figure substantially.Fig. 8 transmission scheme drawing.

1 is fuel tank, the 2nd among the figure, water tank, the 3rd, silencer, the 4th, sky vapour fil, the 5th, arm-rest frame, the 6th, clutch handle, the 7th, shifter bar, the 8th, steering tiller, the 9th, drawbar frame, the 10th, change speed gear box, the 11st, drive wheel, the 12nd, engine mount, 13 driving engines, 14 frames.

10 change speed gear boxs among the figure, one of power-transfer clutch and I speed II speed gear B wherein is housed, the reverse gear shaft fixed gear wheel that reverses gear, can carry out the speed walking by shift fork, three are equipped with steering gear D, by shift fork tractor are turned to, four are equipped with transmission gear E, five are equipped with transmission gear F, change moving velocity, six driven wheel L by shift fork.
