Abstract

The utility model provides a rotary tiller matched with a walking tractor with a front-mounted tail wheel control pedal and a matched structure. A fork-shaped rotary tiller connecting seat is arranged on the rotary tiller, so that the rotary tiller can rotate around a power input shaft of the rotary tiller connecting seat to complete the lifting motion of the rotary tiller; and a fork-shaped connecting seat on the head of a girder of the rotary tiller and a double-bolt connecting seat are also arranged on the rotary tiller, so that the tractor improves the performance and is convenient to mount.

Description

The rotovator of tail-operated pedal-front-mounted type walking tractor and supporting structure

Affiliated technical field

The utility model relates to a kind of rotovator that is used and some novel Connection Block structures on tail-operated pedal-front-mounted type walking tractor.

Background technology

At present, there is not supporting rotovator on the known tail-operated pedal-front-mounted type walking tractor, and the rotovator of adapted is fixed on the former hand tractor, can not be with respect to dilatory body lifting, and this machine adopts the tail wheel fixed structure, so must have a kind of novel rotovator and Connection Block, handgrip and this machine that some are novel supporting.

Summary of the invention

In order to overcome the deficiency that existing rotovator can't be used on this machine, the utility model provides a kind of made rotovator power input shaft with U type Connection Block to rotate the rotovator of finishing lifting therein, and the rotovator casing of the box side power input shaft of central transmission type.The Connection Block of the band twin jack on crossbeam or the bow girder head and fork-shaped Connection Block so that this machine crossbeam is connected firmly and narrow meshed farm implements lifting under handle structure, to realize the various performances of this rotovator and this machine.

The technical scheme that its technical problem that solves the utility model adopts is: this tail-operated pedal-front-mounted type walking tractor tail-gear spindle is to fix, can't lift adjustment, therefore must allow the rotovator lift adjustment, and the best approach of rotovator lift adjustment is to allow the rotovator body rotate around its power input shaft, and rotary tiller shaft just can be finished lifting action.Like this can use the rotovator of the little hand steered and gearbox side power input type that 101 little central transmissions on hand steered are box of sweet osmanthus, also adopt chain and gear to combine or the mode of pure chain drive.Rotary tiller shaft, rotovator rotates the interior of gearbox and the change that shift lever mechanism need not be big.In the rotovator casing, adopt two or three chain speed reducing transmission cases, also corresponding speed change, clutch and chain tensioning mechanism should be arranged certainly.Can adopt chain or belt transmission between rotovator power input shaft and the gearbox power take-off, the structure of the chain of this moment or the outer cover of belt is a two halves opposite place cover structure, but, because its twin shaft is not fixed, so it has axle sleeve and the bearing that cooperates with rotovator power input shaft or tractor motive power output shaft on one side, its other side's housing case is a slotted hole so that the axle in the outer cover can move forward and backward.This rotovator power input shaft axle sleeve outer ring is torn rotating shaft open as lifting, and the coaxial another side of the correspondence of the power input shaft of this machine also should be provided with one and tears axle open and change, also can be that the other end of power input shaft and outer shaft thereof are as turning back axle, two bearing blocks of axle by a fork-shaped of turning back are connected on tractor-drawn frame or the farm implements lifting linking member seat, square tube above the bearing block of fork-shaped or channel-section steel by horizontal stroke two jacks or two perpendicular jacks are plugged on the tractor-drawn frame or the connecting rod base of the farm implements lifting connecting rod that is used to peg graft, the rotovator axle bed of turning back is that the circular shaft bearing that two semicircles are combined to form is connected on two jaws, certainly should be useful on bolt hole seat and bolt that clamp shaft holds, under the situation that adopts sliding shaft base, available plastic mattress reduces wear therein between bearing block and the axle, the fork-shaped rotovator is torn open and is held rotovator in the middle of the shaft seat and tear rotating shaft and the speed change or the transmission case first half open, in order to regulate the length of chain, should be with rotovator fork-shaped Connection Block dimidiation formula structure, half is that square tube or channel-section steel are plugged on the connection jack base that forms on traction frame or the connecting rod base, half is the rotovator of the fork-shaped axle bed of turning back, just long steel plate strikes out fork-shaped, add the bearing block of two semicircles at its two, and use oval bolt hole as connection on the fork-shaped bottom surface and between long trough or the square tube shape connection jack base, axle bed can move up and down with tension chain or belt by relative this machine with rotovator so that the fork-shaped rotovator is turned back, this sample rotovator power output transmission case just can be without tensioning or pinch roller, farm implements lifting handgrip and top yoke are connected on the rotovator body, to finish the lifting of rotovator, there is a hole to be used for wearing the root marline on the following handle on the farm implements lifting handgrip, its use is that the handgrip dop is not snapped in the latch, so that handgrip can the free lifting action under the situation of handling farm implements or rotovator.The rotovator casing adopts cast structure or adopts the box-like body structure of drawing.On 101 little hand steered similar or east wind 12 similar hand tractors, the fork-shaped crossbeam Connection Block that is connected with crossbeam is arranged, just the fork-shaped steel plate is connected in the gear box of tractor both sides, on this machine because this machine crossbeam must secundly, so that tail wheel just in time is pressed in the type ditch, so the big yoke on the crossbeam limit is also asymmetric, but secundly specifically is single ploughshare type deflection the right, and two ploughshare types generally are partial to 5-10cm to the left side, just big yoke center axis deviation crossbeam central axis.The traction frame of hanging trailer and farm implements is all arranged on hand tractor, under the situation of this tail-operated pedal-front-mounted type walking tractor of carry mounting sub-assembly, because this machine crossbeam is arc, there is the Connection Block of the single jack that is connected with traction frame at the farm implements lifting linking member seat that vertical slot shape arranged on the crossbeam head and its back side, because single jack needs careful the adjusting, this machine of making crossbeam deflection is as changing single jack into the twin jack structure, because have three holes on the traction frame.Weld two block plates up and down at the farm implements lifting linking member seat back side exactly, two perpendicular jacks about boring on the steel plate.Two kinds of modes that allow this machine crossbeam deflection are arranged, a kind of is to allow two perpendicular jack bases stretch on one side, make this support shelf structure spare with respect to the vertical secundly of a tractor, another kind is with the oblique layout of the jack on two steel plates, make this support frame sub-assembly inclination secundly, the twin jack Connection Block at the farm implements lifting linking member seat back side on this machine of that is to say crossbeam head is flute profile, and two jackscrew structures about also having, like this just be of great benefit to assembling this tractor, needn't worry to adorn not deflection and the farming problem of difficult occurred, if the tractor-drawn frame of shaped as frame can upwards move two jackscrews, allow the jackscrew structure withstand on above the traction frame on the limit, these two kinds of crossbeam head Connection Blocks can make crossbeam firmer, to adapt to the needs of carry rotovator and tractor heavy duty.

The beneficial effects of the utility model are: can allow these facility that the function of rotary tillage is arranged and have a structure of some new more convenient practicalities.
