On the basis of the tail-wheel controlled pedal superposed walking tractor, different connecting bases on the head of a crossbeam, such as fork-shaped, U-shaped and horizontal-groove shaped connecting bases, a tail-wheel deflection axis with lifting function, an H-shaped riding rack assembly, a novel T-shaped pedal and other structures are adopted to form the variant machines for the tail-wheel controlled pedal superposed walking tractor in different types with different performances.

Description

Tail wheel guide pedal front type hand tractor variant machine

Affiliated technical field

The present invention relates to a kind of on the walker tractor basis improved novel walker tractor, the walker tractor of the novel riding-type used in the paddy field district of especially suiting.

Background technology

A few days ago, known walker tractor is not to be with model riding-type and that carry seat, and " tail-operated pedal-front-mounted type walking tractor " of my invention is because distinguish bigger with walker tractor in the past, so need some later-model structure and parts, could improve its performance, to form the novel walker tractor of different model.

Summary of the invention

Be difficult for the difficult problem on the riding-type walker tractor of my invention, used for some parts that overcome existing walker tractor, technical scheme provided by the invention comprises: because use on the existing trac. mainly contain several different crossbeams and handrail stand, the connection mode of change speed gear box, connect as fork-shaped, the U flute profile connects, the traction frame connects, the handrail stand replaces the form of crossbeam, also have on the crossbeam head vertical slot shape connecting rod base directly by bolted connection with the form on the change speed gear box, comprise and directly weld the type that goes up the tail wheel axis of deflection on the crossbeam back, or the additional form that goes up the tail wheel axis of deflection that connects, and the novel draw-in groove Connection Block behind the crossbeam, the tail wheel mounting assembly set of H type, the pedal weldment of the Connection Block of traction frame pattern and T type, to form the multiple later-model tail-operated forward type trac. of stepping on, can make this machine be applicable to various walker tractor remodeling needs by above parts.

The technical solution adopted for the present invention to solve the technical problems is: all there is the crossbeam that connects change speed gear box or handrail stand the tail wheel axis of deflection front on various walker tractors, it can be arc crossbeam, have plenty of and before crossbeam, wear the fork-shaped Connection Block and be connected in the gear box of tractor both sides, as the little hand steered type of 101 types, have plenty of and wear U flute profile Connection Block before the crossbeam and be connected in below the handrail stand, as the type of workers and peasants-81 type, have plenty of direct with handrail stand replacement crossbeam.As workers and peasants-12 type, the farm implements lifting linking member seat that also crossbeam can be welded on vertical slot shape is upwards in the vertical slot of lengthening, directly the farm implements lifting linking member seat with vertical slot shape replaces traction frame, and be connected on 101 types or the little hand steered change speed gear box Connection Block of sweet osmanthus with bolt, certainly on the vertical slot shape farm implements connecting rod base Connection Block plane that cooperates with the change speed gear box bolt hole should be arranged or be connected steel plate, as there is the plane of band screw at the little hand steered boxed rod seat of 101 types that the are connected in back side, be connected in sweet osmanthus little hand steered just go up must have about vertical slot shape connecting rod base with traction frame on identical two be connected steel plate, in order to make tail wheel axis of deflection and this arbor line that certain deflection be arranged, right avertence 5-10cm during just single ploughshare, and left avertence 5-15cm or center during two ploughshare, just crossbeam has certain deflection to connect, if adopt the tail wheel axis of deflection of band elevating function, axle and lifting screw and following tail-wheel fork should be arranged in its axle sleeve, this is a common structure, and pedal and caudal furca interlock, connecting rod vertical pivot on pedal and the caudal furca is longer, connecting rod bearing is longer, and bumping post is also just longer.The semicircle draw-in groove type Connection Block that clamps the tail wheel axis of deflection is generally arranged on common crossbeam head, bolt hole seat and pressing plate, the flute profile deck extended to the left and right add one or more decks, the tail wheel axis of deflection can be offset to the left or to the right, when being single ploughshare to adapt to this machine the tail wheel axis of deflection be positioned at the center or take over, and the tail wheel axis of deflection is taken back or is hit exactly when two ploughshare, the Connection Block of crossbeam back can also adopt and similar Connection Block of traction frame and connector in addition, certainly Connection Block can be two pairs or how right connection jack, can make connector on the Connection Block have linkage function to the left side, trac. axis or the right to adapt to the variation of trac. list ploughshare or two ploughshares, connector is the channel-section steel or the square tube type connector of twin jack.Welding the mounting assembly set of tail wheel axis of deflection on it, and Connection Block can also be welded on the middle pedal axis of deflection front of crossbeam, two parts before and after with Connection Block crossbeam being divided into.The steel plate pedal welding of racket shape or punching press now before the pedal weldment of this machine also comprises except that previously used pedal or bolted connection form T type pedal weldment at one section pipe the right and left, axle bed is one section axle sleeve and the pedal weldment is turned back, steel pipe is passed through on before and after it or one side, round steel or triangle steel plate are welded on the tail wheel axis of deflection front under the crossbeam, empty certain distance between axle sleeve top and the crossbeam, T type pedal shaft upwards is inserted in the axle sleeve like this, T type pedal shaft the higher authorities have jack, latch and having filled up, in succession vertical pivot on the tail-wheel fork of connecting rod vertical pivot and connecting rod is certainly arranged on the T type pedal, tail wheel that can also carry H type on the connector of crossbeam back is taken the frame assembly set, its structure is that pedal axis of deflection fwd crossbeam is clipped, the pedal axis of deflection is prolonged, extend through short beam become can and the vertical pivot that is connected of draw-in groove, take advantage of at the tail that adopts tail wheel will form H shape under can not the situation of lifting structure and to take turns the mounting assembly set.Prolong and add under the situation of tail-gear spindle lifting screw structure at the inclined to one side wheel shaft of tail wheel, the tail wheel that will form anti-h type is taken the frame assembly set, certainly can weld front said translot shape connector on tail wheel axis of deflection or the pedal axis of deflection, connector is the twin jack Connection Block, about the flute profile connector of two perpendicular jacks the jackscrew structure is arranged, similar with the connector on the rake column cap, and the seat straight beam just welds the direction that the tail wheel axis of deflection stretches out backward, similar seat before having on it.

The invention has the beneficial effects as follows: various structures provided by the invention can adapt on the walker tractor of all kinds of types to be used, form the walker tractor of multiple model, make walker tractor have the needs of better adaptation paddy field district heavy duty high load capacity farm work and the load of raising the efficiency and lighten one's labor.
