Abstract
The utility model is composed of a tractor body, an engine, a gear box, a hitch device. A three-wheel tractor which is ridden and sat through holding handles has the advantages of compact structure and small transition radii. The utility model not only can conveniently and flexibly operate in plastic tunnels, but also can operate between lines of interplanting crops and in glades that steering wheel type tractors and walking tractors can not enter. After back wheels are changed to be blade wheels, the three-wheel tractor can operate in rice fields. After the hitch device at the back of the three-wheel tractor can hang and connect different agricultural implements, a plurality of farmland operation can be completed. When the three-wheel tractor is used, labor intensity is low, and efficiency is high, and the utility model is a miniature agricultural machine with strong practicability.
Description
The utility model belongs to farm machinery, particularly a kind of trac. that articulates multiple work mechanism.
Existing trac., existing steering wheel type and hand-held type.The steering wheel type four-wheeled tractor, horsepower is big, and the power height is suitable for the operation in land for growing field crops very much, but because its complex structure volume is tall and big, can not enter the use in the ranks of hot house, woodland and interplanting crops.Walking tractor is compared with the steering wheel type four-wheeled tractor, and volume is short much smaller, can conveniently enter booth, but the handrail of walker tractor is longer, and turn radius is big, can stay bigger dead angle during operation in the booth, so use still undesirable.Beijing Agricultural University once aimed at operation in hot house and had developed a kind of mini tractor.This trac. has only two-wheeled, and simple in structure, compact, volume is little, operate nimble, but the use of machine will lean on the people walk to grasp at the one skidding, is a kind of manpower power-assist formula machinery.During long working, people's labour intensity is bigger.
The purpose of this utility model is to provide a kind of three wheeled trac.s, with realize can not only be in the paddy field, the nonirrigated farmland operation, can also be nimblely in hot house, the use in the ranks of woodland and interplanting crop, and the people can ride seat operation onboard.
The utility model is by car body, driving engine, change speed gear box, hanging device constitutes, the front-wheel of car body is a single wheel, trailing wheel is a two-wheel, has the wide plane girder of second shape between the front and back wheel, and the front fork that is connected in front-wheel links by thrust bearing and crossbeam, the front fork top extends to the both hands handle, driving engine and change speed gear box are fixed on the crossbeam of car body, between the output of driving engine and the input of change speed gear box, by belt-driving, the outer trailing wheel of also installing of crossbeam is stretched out at the output shaft two ends of change speed gear box thereon, the top of change speed gear box is provided with seat, change speed gear box be provided with shifter bar, hanging device is installed on the aft end face of change speed gear box.During use, the people rides seat on car body, opens engine throttle, and the push-and-pull shifter bar is put into gear and speed governing, two hold handgrip grasps direction, but trac. normal operation just.
The utility model is the handgrip sitting type, does not need the people to grasp at ground running during operation, makes operation easily, reduces labor intensity greatly.During driving, man-machine height is lower than the height of people when upright, maximum width (trailing wheel place) only is 350～650 millimeters, turn radius is about 1 meter, so, not only can operation in hot house easily and flexibly, but also approach axis disc type and the inaccessiable interplanting of walking tractor crop in the ranks with slash in operation.Range of use greatly enlarges.
Below in conjunction with the accompanying drawing embodiment that has a talk.
Structural representation when Fig. 1 is positioned at the crossbeam lower plane for the utility model driving engine.
Structural representation when Fig. 2 is positioned at plane on the crossbeam for the utility model driving engine.
Fig. 3 articulates the scheme drawing that hangs farm implements for the utility model.
Fig. 4 pulls the scheme drawing of farm implements for the utility model articulates.
Fig. 5 is the structural representation of blade wheel for the utility model trailing wheel.
The crossbeam 1 of car body has width and is about 180 millimeters plane, the side is " second " shape, make crossbeam form two planes up and down, front fork 2 passes on the crossbeam place, end, plane and by thrust bearing the two is linked, the lower end of front fork links by front axle and bearing and front-wheel 3, the top links 4 with the both hands that extend to the left and right, and driving engine 5 and change speed gear box 6 are provided with shifter bar 13 by linking for hole and the crossbeam installed and regulate of leaving on the crossbeam on the change speed gear box.For lowering the center of gravity, driving engine can all be installed on the lower plane of crossbeam, as shown in Figure 1 with change speed gear box.When needs enter between crop row or plough in the paddy field when whole, in order not make crop be subjected to the infringement of engine exhaust or not allow water inflow of the engine in the paddy field, also driving engine can be moved on on the last plane of crossbeam, and change speed gear box reach is as shown in Figure 2 relatively.Driving engine can adopt the diesel engine of 165,175 or 180 types.Linked by belt-driving 7 between the output of driving engine and the input of change speed gear box, the output shaft of change speed gear box stretches out outside the casing and trailing wheel 8 links.Seat 9 is installed on the gear box between the trailing wheel, and hanging device 10 is installed on the aft end face of gear box.This hanging device has a mounting plane, with the through hole that has on the ears that this plane links to each other perpendicular to these ears.The form of the connection part of the various agricultural machinery and implement that can need by farming and taking various forms.The hanging device of ears level perforation formula as shown in Figure 3 can articulate as class mounting implements such as plough, rake, cultivator, trench digging ridger, paddy field harrow, field-finishers; The extension of ears vertical perforation formula is as shown in Figure 4 pressed device, can articulate class pull-behing implements such as sower, tractor-propelled harrow, cultivator, motor-driven sprayer-duster, trailer.Trac. is ploughed in the paddy field when whole, is slip-skid prevention, the back rubber tire should be driven, and changes two blades wheels into or only pacifies a blade wheel 12 and increase by one at another side and support 11, as shown in Figure 5.
Claims (4)
1. three wheeled trac.s, by car body, driving engine, change speed gear box, hanging device constitutes, and it is characterized in that: the front-wheel of car body is a single wheel, and trailing wheel is a two-wheel, has the wide plane girder of second shape between the front and back wheel, the front fork that is connected in front-wheel links by thrust bearing and crossbeam, and the front fork top extends to the both hands handle, and driving engine and change speed gear box are fixed on the crossbeam of car body, between the output of driving engine and the input of change speed gear box, tool is by belt-driving, and the output shaft two ends of change speed gear box are stretched out crossbeam and also trailing wheel are installed thereon outward, and the top of change speed gear box is provided with seat, change speed gear box is provided with speed change, and hanging device is installed on the aft end face of change speed gear box.
