Abstract
A wheeled tractor front lifting device consists essentially of an upper pull rod, a lower pull rod, a lifting oil cylinder, a left lateral plate, a right lateral plate, a suspension shaft, a reinforcing plate and corresponding connectors and pipes. The whole device is disposed on the front bracket of the tractor, wherein the lower pull rod has frame type welded structure and is foldable, and a rapid coupling device is disposed at the front of the device. The device can only swing up and down around the suspension shaft, unable to swing left and right. The lifting oil cylinder can be directly connected on the lower pull rod, and the valve control handle for multi-way hydraulic pressure output controls the retraction of the lifting oil cylinder, so as to lift the entire lifting device.
Description
(1) technical field
The utility model belongs to the tractor field, relates to the preposition lifting device of a kind of wheel tractor.
(2) background technology
At present, at home on the various model wheel tractors of Sheng Chaning, lifting device is all at the tractor rear portion, in the time of need being equipped with as preposition facility such as reaping apparatuses to some, often facility are mentioned by devices such as sprocket wheel, chain, pulley, steel wire ropes, perhaps need to carry on the facility hoisting mechanism, structure is all very complicated, and hoisting depth is also very limited.When tractor carries out multiple operation, facility can only be designed to compound facility, be suspended on the rear portion of tractor, can not make full use of tractor power, the tractor front portion will increase many counterweights simultaneously, and entire job unit weight is increased.Articulate and the lifting problem by using this device can solve the preposition facility of tractor, make things convenient for tractor to carry out front and rear combined multiple operation.
(3) summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, easy accessibility, the preposition lifting device of service-strong wheel tractor, can make things convenient for tractor to carry out front and rear combined multiple operation.
The technical solution of the utility model is: the preposition lifting device of wheel tractor mainly is made up of upper connecting rod, lower link, lift cylinder, lifting support, suspended axle etc.It is characterized in that: left and right sides plate is set on the lifting device and promotes the support connection and be fixed on the front rack of tractor.Left and right two lower links middle part and rear portion be affixed to become tower structure, the front end of lower link is welded with the quick hanging mechanisms of hook-type, the lower link middle part is provided with connecting pin and can folds it, the rear portion of lower link is by lining and suspended axle socket, lower link can not swing, and can only swing up and down around suspended axle.Suspended axle is packed on the left side plate.Be provided with stiffener between biside plate.One end of upper connecting rod one end and lift cylinder all is hinged on and promotes on the support, and the lift cylinder other end is associated on the lower link, and the upper connecting rod other end links to each other with equipped facility.Lift cylinder links to each other with the tractor banked direction control valves by pipe-line system, controls its lifting by the banked direction control valves control crank in the driver's cabin.
(4) description of drawings
Fig. 1 is the front view of the preposition lifting device of the utility model wheel tractor.
Fig. 2 is the vertical view of the preposition lifting device of the utility model wheel tractor.
(5) embodiment
Fig. 1, preposition lifting device shown in Figure 2 mainly are made up of upper connecting rod 1, lower link 2, lift cylinder 3, pipe-line system 4, lifting support 5, stiffener 6, side plate 7, lining 8, suspended axle 9 etc.Wherein, promote support 5 and be installed in tractor front rack front, two blocks of side plates 7 are installed on the tractor front rack left and right side by bolt, are the rigidity that improves entire mechanism, will promote support with bolt again and left side plate links together.Lining 8 is fitted in the hole of lower link 2 back, and suspended axle 9 passes lining 8 and is fixedly supported on the biside plate 7.Two lift cylinders, 3 one ends are installed in the both sides that promote support 5, the other end is vertically mounted on the lower link 2, lifting drive lower link by two lift cylinders 3 swings up and down around suspended axle 9, makes the implement lift of suspension, and the height of implement lift complies with the national standard requirements.Stiffener 6 is installed between the biside plate 7, prevents its torsional deformation.Upper connecting rod 1 one ends are installed on the center line that promotes support 5, and the other end links to each other with the facility that articulated, it and lower link 2 formation spatial triangles, and facility are firm articulates in assurance.The anterior coupling part of upper and lower pull bar size is all by the national standard design, with the versatility that guarantees that facility articulate.For reducing the length of whole preposition lifting device, lower link 2 middle parts are provided with movable connecting pin, and the time spent can not extract connecting pin out, fix with same connecting pin after making lower link folding again.Whole preposition lifting device links to each other by the hydraulic pressure output banked direction control valves of pipe-line system 4 and tractor, and with the interior banked direction control valves joystick control equipment lifting of driver's cabin.
