Abstract

The utility model relates to a miniature three-wheel tractor, a machine frame of which is provided with a front steering wheel, a rear left driving wheel, and a rear right driving wheel. The rear part of the machine frame is provided with a plough body through a lifting-slipping mechanism; the lower end of the plough body is connected with a circular guide rail; the middle part is hinged on a connecting rod, the other end of which is hinged on a crank which is arranged on a quadrate guide rail through a slipping sleeve; the quadrate guide rail is fixedly connected to the other crank which is connected with a lifting drawing rod, and the other end of the lifting drawing rod is connected to an operating rod. The utility model has the advantages of small size, small motive power, flexible turning, convenient operation, and small tillage cross head. The miniature three-wheel tractor can conduct tillage, seeding, and irrigation to small land blocks, orchards, and greenhouses, and the miniature three-wheel tractor can be also used for transportation.

Description

The miniature tri wheel trac.

The utility model relates to field machine, and concrete is a kind of miniature tri wheel trac..

Trac. is main field machine, and the trac. of rural area use now mainly contains three classes; 1, four-wheeled tractor, 2, crawler-tread tractor, 3, walker tractor.Four-wheeled tractor and crawler-tread tractor horsepower are big, (all more than 12 horsepowers), volume is big, the manufacturing cost height, the arable land cross-peen is long, to little plot, the fruit tree garden, booth can't be cultivated, though walker tractor Miniaturizable (below 12 horsepowers) but handle inconvenient, turn by power-transfer clutch, though it be its steamboat of three wheels (during the arable land with two wheels) in drive wheel (chevron tire wheel) back, only play a supportive role, do not play and turn to its fuselage of effect longer, it is inconvenient to turn, also inconvenient to the farming of little plot, and the people is at the heel when ploughing walks, there is not lifting mechanism, lift by manpower when plowing, labour intensity is big, can not sow.

The purpose of this utility model provides a kind of miniature tri wheel trac., and volume is little, and power is little, turn flexibly, and control comfort, the arable land cross-peen is little, can be to little plot, fruit tree garden, booth is ploughed, sows, is irrigated the fields, and also can be used for transportation.

The purpose of this utility model is achieved in that

A kind of miniature tri wheel trac. mainly is made up of frame, wheel, driving engine, speed-changing mechanism, engaging and disengaging gear, braking mechanism, steering hardware, it is characterized in that:

Frame is made of chassis and the place ahead turning sleeve, steering handle, steering handle is housed on the turning sleeve connects the wheel flutter that is loaded in the front fork, and shock absorber is housed on the front fork; Change speed gear box, power-transfer clutch and the back axle that connects driving engine is equipped with at the rear on chassis, and the left and right driving wheel is equipped with at the back axle two ends;

At the rear of frame with lifting--slipping mechanism is equipped with the plough body, the slipping part branch of this mechanism comprises a round guide and a square guide rail, this round guide is contained in the left and right bearing of frame posterior end, and this round guide cylindrical is set with the sliding sleeve that is fixed in the plough body, and sliding sleeve is provided with fixing screw; This square guide rail is contained in its two ends circular shaft in the left and right bearing of frame rear side and turns, and the square guide rail middle part is set with sliding sleeve, and this sliding sleeve has the crank that upwards stretches out, and the hinged connecting rod of this crank, this connecting rod end in addition are articulated in the middle part of plough body;

The operating parts of described lifting part is that a pull bar, this pull bar one end are articulated in a crank, and this crank side of having cover is fixed in described square guide rail; This pull bar is held to be connected in addition and is located at chaufeur joystick at one's side, and when the driver's operation joystick, lifter drawing bar pulling square guide rail rotates, and realizes ploughing the ascending, descending of body by the connecting rod that connects the plough body.

The utility model has following actively useful effect:

1, this machine is the fraction horsepower three-wheel type trac. that declines, and power is below 12 horsepowers, and this machine has designed wheel flutter, shock absorber and steering handle before chevron tire wheel, reached like this turn to flexibly, control comfort.

2, the rack construction of this machine, its front and rear wheel distance and left and right wheelspan are all little, and it is little to have reached turn radius like this, is fit to by dress low-power machine.

3, this machine is provided with lifting mechanism, and chaufeur is seated and drives to plough, and has alleviated people's labour intensity greatly.

4, this machine is provided with slide mechanism, makes these facility have the limit to plough function, so that will plough do not press others' ground during ground.

Generally speaking, this machine is that a kind of volume is little, and power is little, turn flexibly, and control comfort, the arable land cross-peen is little, can plough, sows, can also irrigate the fields, and transportation function is arranged little plot, fruit tree garden, booth.

Now in conjunction with the accompanying drawings:

Fig. 1 is the construction profile scheme drawing of the utility model one embodiment;

Fig. 2 is lifting among Fig. 1--the structural representation of slide mechanism;

Fig. 3 is the structural representation of the underframe of Fig. 1 mid frame;

Fig. 4 is the birds-eye view of Fig. 3.

Accompanying drawing number:

9, crank 901, sliding sleeve

10, connecting rod 11, (lifting) pull bar

12, crank 121, side's cover

Please refer to Fig. 1, miniature tri wheel trac. of the present utility model mainly is made up of frame, wheel, driving engine, speed-changing mechanism, engaging and disengaging gear, braking mechanism, steering hardware.

Frame 1 is made of chassis 101 and the place ahead turning sleeve 102 and sees Fig. 3 Fig. 4, steering handle 2, steering handle 2 is housed on the turning sleeve connects a wheel flutter 3 that is loaded in the front fork, and shock absorber 4 is housed on the front fork; Change speed gear box, power-transfer clutch and the back axle that connects driving engine is equipped with at the rear on chassis, and left and right two drive wheels 5 are equipped with at the back axle two ends;

Please be simultaneously with reference to Fig. 2, at the rear of frame 1 with lifting--slipping mechanism is equipped with plough body 6, the slipping part branch of this mechanism comprises a round guide 7 and a square guide rail 8, this round guide 7 is contained in the left and right bearing 103 of frame posterior end, this round guide cylindrical is set with the sliding sleeve 601 that is fixed in plough body 6, and sliding sleeve is provided with fixing screw 602; This square guide rail 8 is contained in its two ends circular shaft 801 in the left and right bearing 104 of frame rear side and turns, square guide rail 8 middle parts are set with sliding sleeve 901, this sliding sleeve 901 has the crank 9 that upwards stretches out, these crank 9 hinged connecting rods 10, and this connecting rod 10 end in addition is articulated in the middle part of ploughing body 6;
