Description
Technical field
The utility model relates to a kind of mower.
Background technology
The mowing of mower highly is that the ground clearance by cutter decides because the fuselage of mower is mounted on the wheel shaft, so initial mower by changing wheel or the adjusting wheel shaft is regulated, obvious this control method is cumbersome.After this production firm has designed a kind of governor motion comparatively easily, this mechanism is in the inboard pin joint a slice respectively of the wheel shaft of four wheels fork, fulcrum and back fulcrum before being connected with respectively between two forks of front-wheel and trailing wheel, the mower fuselage just is installed on these two fulcrums, and there are two front and back forks of a side L-shaped, be connected with connecting rod between another termination of L shaped fork, be fixed with a slice poke rod on the back fulcrum, be connected with adjusting rod on the poke rod, adjusting rod stretches out body from bottom to top, because the distance between two fulcrum shafts is (because fuselage is installed) of fixing, so upwards extract or be pressed down into adjusting rod, can make fork produce swing, thereby make two fulcrums carry out lifting, reach and regulate promptly the mow purpose of height of cutter ground clearance.But, thisly rotate the back fulcrum by poke rod by adjusting rod, swing fork again, the structure of lifting fuselage relatively require great effort when handling, and the location of adjusting rod is unreliable, and lifting distance is not directly perceived.
Summary of the invention
The purpose of this utility model is: a kind of mower mowing arrangement for adjusting height is provided, and this device has changed existing governor motion, not only handles laborsavingly, easy to use, and the location of adjusting rod is reliably directly perceived, and feel is very light.
The technical solution of the utility model is: a kind of mower mowing arrangement for adjusting height, comprise the fork of pin joint on front axle and hind axle respectively, be connected with preceding fulcrum between two front roll bars, be connected with the back fulcrum between the two back forks, body is installed on preceding fulcrum and the back fulcrum, have at least between front and back two forks of a side and be connected with connecting rod, on two forks with the front and back wheel shaft, three pin joint points of front and back fulcrum and connecting rod are wired to triangle respectively, have on the fork in front and back two forks of described connecting rod pin joint to be connected with upwardly extending adjusting rod, adjusting rod is by the detent mechanism location that is fixed on the body.
The further technical scheme of the utility model is: a kind of mower mowing arrangement for adjusting height, comprise the fork of pin joint on front axle and hind axle respectively, be connected with preceding fulcrum between two front roll bars, be connected with the back fulcrum between the two back forks, body is installed on preceding fulcrum and the back fulcrum, have at least between front and back two forks of a side and be connected with connecting rod, on two forks with the front and back wheel shaft, three pin joint points of front and back fulcrum and connecting rod are wired to triangle respectively, be connected with upwardly extending adjusting rod on the back fork in front and back two forks of described connecting rod pin joint, adjusting rod is by the detent mechanism location that is fixed on the body; Described detent mechanism is the location-plate that is installed on the body, and location-plate is provided with several positioning recess, and the neck of adjusting rod embeds in the positioning recess; The lower end of described adjusting rod is bent into horizontal bearing pin, and the transverse bolt pivot pin is connected on the both sides bent plate of fork; Horizontal bearing pin between the bent plate of described both sides is provided with torsion spring adjusting rod is pressed in the positioning recess; In the limited bayonet on the bending plate of the nearly transverse bolt shaft portion embedding of described adjusting rod fork, limited bayonet is identical with the opening direction of positioning recess.
The more detailed technical scheme of the utility model is: a kind of mower mowing arrangement for adjusting height, comprise the fork of pin joint on front axle and hind axle respectively, be connected with preceding fulcrum between two front roll bars, be connected with the back fulcrum between the two back forks, body is installed on preceding fulcrum and the back fulcrum, have at least between front and back two forks of a side and be connected with connecting rod, on two forks with the front and back wheel shaft, three pin joint points of front and back fulcrum and connecting rod are wired to triangle respectively, be connected with upwardly extending adjusting rod on the back fork in front and back two forks of described connecting rod pin joint, adjusting rod is by the detent mechanism location that is fixed on the body; Described detent mechanism is the location-plate that is installed on the body, and location-plate is provided with several positioning recess, and the neck of adjusting rod embeds in the positioning recess; The lower end of described adjusting rod is bent into horizontal bearing pin, and the transverse bolt pivot pin is connected on the both sides bent plate of fork; Horizontal bearing pin between the bent plate of described both sides is provided with torsion spring adjusting rod is pressed in the positioning recess; In the limited bayonet on the bending plate of the nearly transverse bolt shaft portion embedding of described adjusting rod fork, limited bayonet is identical with the opening direction of positioning recess; Described adjusting rod is connected on the fork of back, is connected with the extension spring with its post-tensioning between this back fork and the body.
The utility model has the advantages that:
1. the utility model directly is connected adjusting rod on the fork, has increased the arm of force of adjusting rod greatly, stirs the upper end swing of adjusting rod during adjusting, and is more laborsaving.
2. adjusting rod of the present utility model lower end is bent into the transverse bolt pivot pin and is connected on the fork of back, adjusting rod can be swung and deviates from positioning recess, and the adjusting rod of deviating from behind the positioning recess could swing be regulated the height of mowing.
Since body of the present utility model be installed in before and after on the fulcrum, and be connected with connecting rod between the fork of front and back, the front and back fork has the interlock effect, lifting simultaneously makes machine make upper and lower translation with noting when lifting and moves, the mowing effect is relatively good.
