Abstract
A single-wheel miniature walking tractor is composed of basket-type frame structure, single-wheel drive mechanism, shoulder walking unit, hand turning unit, and features that the speed of running is about one meter per second. The driving wheel is set near the digging device, the hub is a set of planetary gear hydraulic motor, the special engine outputs hydraulic oil directly, and the three-position two-way reversing valve controls the hydraulic motor to run. A stand is arranged in the machine. The rear part of the machine is provided with a friction block which is connected with the tail end of the V-shaped plate spring and takes the driving wheel as a fulcrum to elastically adjust the tunneling depth. The harrow can be operated by changing the harrow connecting piece.
Description
A kind of agricultural machinery that is used for ploughing whole soil, full name " single-wheel miniature walking tractor ".
The tractor that uses only adapts to farming on smooth ground at present.It is small hand tractor, also be left-right wheeled machinery entirely, can not be in the farming on the ground of scraggly inclined slope, can not walking on the path of labyrinth frustration, (first 32 pages of engineering goods catalogue in June, 86 front pages are compiled by the tool Ministry of Industry according to circumstances, standard book number 150336058), before and after the two wheeled mini tractor patent No.s 962178942, also because of body is too heavy, can not go up a slope pickaback and in the hillside fields farming.A kind of primary tillage equipment that adapts to the hillside fields operation should be arranged.
The utility model purpose provides a kind of single-wheel miniature walking tractor, can plough whole hillside fields in the knob, also can plough leveling ground and rice field, when the labyrinth path can not pass through, and can be pickaback to operating location.
The utility model is a single wheel drive mechanism, basket open frame structure, hydraulic drive.Establish the driving device before the machine, establish driving wheel near the driving device, wheel hub is a cover planetary gear hydraulic motor, also can adopt the alternate manner transmission.Establish the station frame in the machine, land support when resting, pack up backward during walking.Rear lower does not have friction block, connects elasticity fine setting tunnelling footage with the V-type plate spring.Back middle part mounted engine drives hydraulic oil pump output hydraulic oil, and petroleum pipeline is made rack construction simultaneously, constitutes hydraulic circuit with hydraulic motor, drives the hydraulic motor running, establish advance, retreat, 0 third gear, control with three two way selected valves.The carburetor place establishes the adjusting throttle, about one meter of control travel speed each second.Fuel tank storage of fuels oil is established in the upper back.Back top oil transportation pipe end is established cock, takes off cock and adds hydraulic oil.Handrail is established at middle part, top, back, is linked as integral body with arc frame.Arc frame hollow can be walked and portable tune pickaback.To tunnel device during flat rake operation and take off, and flat rake connector will be installed be connected with flat rake, and the V shaped slab spring be taken off again, change retreats to advancing, and both can put down and harrow operation.
Owing to adopted such scheme, satisfied the knob instructions for use.
Drawing explanation: sequence number 1, driving device among the figure, 2, flat rake connector, 3, arc frame, 4, engine, 5, fuel tank, 6, cock, 7, handrail, 8, three two way selected valves, 9, carburetor, 10, friction block, 11, the frame of standing, 12, driving wheel.
Embodiment: driving device 1 is the special-purpose member of soil deeptillage, this part can be taken off when putting down the rake operation.Flat rake connector 2 connects flat rake and main frame, the V shaped slab spring is taken off again, and becomes to retreat to advancing, and both can put down the rake operation, this part can be taken off during ploughing work.Arc frame 3 is linked to be a basket formula overall structure with petroleum pipeline, and frame hollow is convenient to walk pickaback and portable tune.Engine 4 is this mechanomotive force source, is designed to special engine, directly exports hydraulic oil and drives the hydraulic motor running.Fuel tank 5 storage of fuels oil is for engine operation.Cock 6 confining liquid pressure pipe mouths.Handgrip part when handrail 7 is this machine of operation.Three two way selected valve 8 control hydraulic motor rotation directions: a left side pushes away and is that forward gear, the right side push away to retreating retaining, and the centre is a parking position switch.Carburetor 9 sides are established the adjusting throttle: pull out 0 and be the idling retaining, 1,2 are the work retaining.Friction block 10 is connected in the V shaped slab spring end, and the hand handrail is fulcrum with the driving wheel during work, the flexible adjustment tunnelling footage.The frame 11 of standing lands support when resting, pack up backward during work.Driving wheel 12, wheel hub are a cover planetary gear hydraulic motor, also can adopt the cycloid internal gear motor, its petroleum pipeline and three two way selected valves 8, and engine 4 constitutes the loop, is subjected to hydraulic oil effect rotary work.
During this machine of use, check the tightness of bolt everywhere earlier, the requirement of fuel oil, the full scale position of hydraulic oil, lubricating oil is drawn out to throttle the work retaining again, and dextrorotation is depressed with sudden force and can be started after gently pressing starting handle (seeing the engine left side) to feel to enter gear.Unclamp starting handle after the starting, because the pulling force of return spring, starting handle is got back to zero-bit automatically.As required throttle is pulled to 1 grade or 2 grades, a left side pushes away reversal valve (right side pushes away reversal valve when retreating), lifts handrail, and the driving device is gone into ground, and the slow handrail of pressing is to the suitable degree of depth.Need the fine setting direction of advance, frame is banking got final product.During time-out reversal valve is pushed into 0, throttle is pulled to 0, closes the oil circuit switch during shutdown, loosens throttle and promptly shuts down.
Claims (2)
1, a kind of miniature walking tractor with the engine source that is used as power, is used for ploughing the agricultural machinery in whole soil; It is characterized in that a basket open frame structure, single wheel drive mechanism, can walk pickaback and portable tune, establish the driving device before the machine, establish driving wheel near the driving device, wheel hub is a cover planetary gear hydraulic motor, special engine is directly exported hydraulic oil, by the running of three two way selected valve control hydraulic motors, establishes friction block behind the machine, be connected in the V-type plate spring end, the flexible adjustment tunnelling footage carries out farming.
2, mini tractor according to claim 1 is characterized in that the driving wheel wheel hub is a cover cycloid internal gear motor.
