Abstract

The utility model discloses a walking tractor which comprises a carriage (22), a power device (5), an operating mechanism (15) and a running gear which comprises a group of front wheels, a group of rear wheels (1 and 11) and two rubber caterpillar bands (8) which are used for joining the front wheels and the rear wheels (1 and 11) together. Tension wheel devices are arranged between the front wheels and the rear wheels. The utility model can solve the problem that a walking tractor is difficult to cultivate at fields after the weather rains. Particularly, when wheat is harvested, a harvester can not harvest at fields under the condition that the fields are wet, and a caterpillar band type walking tractor which is used can solve the problem and protect peasants' labor fruits from losing.

Description

A kind of walker tractor

The utility model relates to a kind of field machine, especially a kind of walker tractor, walker tractor is a kind of little and nimble field machine, generally use in vast rural area, because itself is in the mountain area, to carry out operation be that other large and medium-sized field machine can't replace in places such as hills, orchard, warmhouse booth.But situation about wetting behind rain is descended, even if small hand tractor also is difficult to farming down, results in hand cramps for friend peasant.

The purpose of this utility model provides a kind of situation that can wet and descends the crawler type walker tractor of following ground farming behind rain.

The technical solution of the utility model is: a kind of walker tractor, comprise vehicle frame, engine installation, steering unit and running gear, before above-mentioned running gear comprises, the two groups of wheels in back and two will before, trailing wheel is associated in rubber belt track together, before, trailing wheel comprises wheel shaft and wheel hub, uniform horizontal spoil disposal tooth on the circumference cambered surface of wheel hub, have annular groove at the cambered surface middle part, have the interruption through hole, between two spoil disposal teeth, have mudhole in the bottom of annular groove, the inner face of rubber belt track is the light face, vertically there is projection at the middle part, and the annular groove on this projection and the wheel hub is complementary, the horizontal uniform in-line anti-slop serrations in outside.

Described walker tractor, preceding, an expansion tightening wheel device is respectively adorned at the middle part of the two groups of wheels in back, this device comprises unsteady expansion tightening wheel, expansion tightening wheel support and the pivot shaft of being with damping spring float, before on the arc wheel face of above-mentioned unsteady expansion tightening wheel annular groove being arranged and being equipped with, latter two cleaning shoe, cleaning shoe is a T shape plate, annular groove on its vertical plate face and the expansion tightening wheel cambered surface is complementary, its transverse plate face is fixed on the expansion tightening wheel support that floats, the pivot shaft upper end of band damping spring links with vehicle frame, lower end and unsteady expansion tightening wheel support link, and in the outside of the expansion tightening wheel that floats baffle plate are housed.

Described walker tractor is equipped with the rubber belt track swelling device on the wheel shaft of front-wheel, this device comprises the front-wheel adjusting slider, slide rail and adjusting bolt.

Owing on the wheel of walker tractor, install rubber belt track additional; so just can increase wheel over the ground area of contact and take off power over the ground; reduce the ground pressure of wheel unit plane simultaneously; prevent wheel sinkage, though the situation that behind rain, wets do not influence yet walker tractor descend farming, particularly when wheat harvest; if situation about wetting with running into; reaper can not gather in with descending, uses the crawler type walker tractor just can solve this difficult problem, and protection peasant's work fruit is not suffered a loss.To take off power over the ground big because of crawler belt again, thereby tractive force is increased, and is beneficial to and deep ploughs, and when trac. travelled on the road surface, because rubber belt track is from heavy and light, the area that contacts to earth was big, can reduce the damage and the road maintenance expense of road pavement so greatly.

Below in conjunction with drawings and Examples the utility model is described in further details:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the utility model structural representation;

Fig. 3 is an expansion tightening wheel device scheme drawing;

Fig. 4 is the car wheel structure scheme drawing;

Fig. 5 is the wheel cutaway view.

Structure of the present utility model such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, with shown in Figure 5, comprise vehicle frame 22, engine installation 5, steering unit 15 and running gear, before running gear comprises, the two groups of wheels 1 in back, article 11 and two, with front and

back wheel

1,11 are associated in rubber belt track 8 together, before,

trailing wheel

1,11 comprise wheel shaft 2 and wheel hub 3, uniform horizontal spoil disposal tooth 27 on the circumference cambered surface of wheel hub has annular groove 26 at the cambered surface middle part, has in the bottom of annular groove 26 and is interrupted through hole 30, between two spoil disposal teeth 27, have mudhole 25, the inner face of rubber belt track 8 is the light face, and the middle part has vertical protruding 36, and this projection 36 is complementary with annular groove 26 on the wheel hub.The horizontal uniform in-line anti-slop serrations 10 in outside, preceding, the two groups of wheels 1 in back, an expansion tightening wheel device is respectively adorned at 11 middle part, this device comprises the expansion tightening wheel 21 that floats, expansion tightening wheel support 32 and the pivot shaft 31 of being with damping spring float, float annular groove 26 is arranged on the arc wheel face of expansion tightening wheel 21 and is equipped with before, latter two cleaning shoe 33, cleaning shoe 33 is a T shape plate, annular groove 26 on its vertical plate face and the expansion tightening wheel cambered surface is complementary, its transverse plate face is fixed on the expansion tightening wheel support 32 that floats, pivot shaft 31 upper ends and the vehicle frame 22 of band damping spring link, lower end and unsteady expansion tightening wheel support 32 link, and in the outside of expansion tightening wheel baffle plate 6 are housed, and on the wheel shaft 3 of front-wheel 1 the rubber belt track swelling device are housed, this device comprises front-wheel adjusting slider 20, slide rail 19 and adjusting bolt 18.

Using method of the present utility model is as follows:

Engine installation 5 is contained on the vehicle frame 22, and vehicle frame 22 links with change speed gear box 13, and trailing wheel 11 is passed to after power is passed to change speed gear box 13 again in V-belt 9, and trailing wheel 11 drives rubber belt track 8, and rubber belt track 8 drives front-wheel 1 again makes trac. to overtake.The elasticity of rubber belt track 8 can realize by adjusting adjusting bolt 18 drive front-wheel slide blocks 20.For preventing that stone is clipped in damage wheel and crawler belt in wheel and the rubber belt track, at forward and backward wheel 1, the expansion tightening wheel device is housed between 11, baffle plate 6 is housed outside it, and baffle plate 6 is equipped with on the unsteady expansion tightening wheel 21 in the expansion tightening wheel device, makes baffle plate 6 with its upper and lower activity, in order to avoid baffle plate 6 wearing and tearing rubber belt tracks 8, expansion tightening wheel 21 can't be established mud hole owing to float, and available cleaning shoe 33 scrapes off earth, and earth is discharged by the mudhole on the front and
