Description
Technical field
The present invention relates to field of agricultural machinery, particularly a kind of pressure grass structure of mower and the mower with this pressure grass structure.
Background technology
Mower need regulate the terrain clearance of the blade of mower according to required mowing height when mowing, common way regulates the wheel of mower compared to the height of mower fuselage, owing to rolling on the ground in wheel ground of must fitting, regulate wheel compared to blade terrain clearance after the height of mower fuselage and correspondingly to change, conflict and cause mower to tilt to prevent weed breaker structure lower than the bottom of wheel thus with ground, rigidity occurring or damage, existing mower is after adjustment wheel height, weed breaker structure on wheel moves with wheel simultaneously, thus weed breaker structure may be caused can not to fit careless face, thus affect normal grass cutting action.
Summary of the invention
The object that the present invention will reach is to provide a kind of mower, occurs to guarantee while rigidity is conflicted that cylinder presses grass smoothly avoiding cylinder and bottom surface.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of pressure grass structure of mower, comprises cylinder, handle and two groups of adjusting devices, also comprises the locating shaft fixing with mower body relative position; Often organize the third connecting rod that adjusting device comprises first connecting rod, second connecting rod and bending, the two ends of first connecting rod are rotationally connected with handle, second connecting rod respectively, the two ends of second connecting rod are rotationally connected with first connecting rod, third connecting rod respectively, the two ends of third connecting rod are connected with one end of cylinder, second connecting rod respectively, the bending place of third connecting rod and one end of locating shaft are rotationally connected, the bending place of third connecting rod is higher than the axis of cylinder, and when first connecting rod and second connecting rod are in same straight line, the junction of third connecting rod and second connecting rod is in extreme higher position; Also be provided with between two place's second connecting rods of two groups of adjusting devices, the junction of third connecting rod and parallel with locating shaft heighten bar, heighten bar and second connecting rod is rotationally connected.
When raising wheel, pulling handle makes first connecting rod move to the direction away from cylinder, first connecting rod affects second connecting rod and third connecting rod, the angle of second connecting rod and first connecting rod is made to increase the height also simultaneously raising the junction of second connecting rod and third connecting rod, thus raise the height heightening bar, thus raise wheel, meanwhile, third connecting rod forward rotates, one end height reduction that third connecting rod is connected with cylinder, namely roller height reduces, namely when wheel is raised, cylinder reduces, because the blade terrain clearance being equivalent to mower when wheel is raised reduces, therefore when blade terrain clearance reduces, cylinder terrain clearance is constant, can guarantee that pressure grass is unaffected.Use the operation of contrary to raise cylinder when reducing wheel, when also guaranteeing that blade terrain clearance raises, cylinder terrain clearance is constant, and pressure grass is unaffected.
Further, one end that described third connecting rod is connected with cylinder is provided with through hole, and cylinder is provided with fitting key, and cylinder is connected with third connecting rod through through hole by fitting key, is convenient to take off cylinder and does repairing replacing.
Further, described cylinder comprises main shaft and cylinder face, cylinder surface cover is outer and can around the axis relative sliding of main shaft with main shaft in main shaft, described fitting key is located on main shaft, and fitting key is provided with pin-and-hole, can insert latch in pin-and-hole, described through hole is profiled holes, namely the main shaft of cylinder is relative with third connecting rod fixing, and the cylinder face of cylinder is connected with main axis, thus improves the service life of adjusting device.
Further, also comprise stabiliser bar, stabiliser bar is provided with groove, groove closed at both ends, described bar of heightening also can slide through groove perpendicular to stabiliser bar in groove, when heightening bar and moving with third connecting rod, second connecting rod, heightens bar and slides in the groove of stabiliser bar, stabiliser bar can reduce the vibrations and inclination of heightening bar, guarantees the wheel synchronous coordination of both sides.
Further, described handle comprises lever and stock, stock one end and lever are fixed, the other end and first connecting rod are rotationally connected, be rotationally connected with the fuselage of mower in the middle part of stock, shaft parallel is in locating shaft, lever, locating shaft are positioned at the same side of the junction of stock and first connecting rod, thus reach when handle moves to the direction near cylinder, first connecting rod moves to the direction away from cylinder, and wheel is raised, and vice versa, because operating personnel's general station is in locating shaft side, arranges like this and operating personnel can be made comparatively laborsaving.
The present invention discloses a kind of mower, the body of described mower is provided with above-mentioned pressure grass structure, and mower also comprises two wheels, and wheel and mower body are rotationally connected.
Further, described third connecting rod bending place is to adding that the section radius of cylinder is less than the radius of wheel with the spacing of cylinder junction, preventing the bottom of the cylinder when regulating wheel height lower than the bottom of wheel, preventing cylinder and ground from rigidity occurring and conflicting and cause mower to tilt or damage.
After adopting technique scheme, tool of the present invention has the following advantages:
When wheel is raised or reduces, when namely mower blade terrain clearance reduces or raises, the roller height of weed breaker structure is constant, guarantees to press grass effect to play perfect.
