Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of mower, particularly a kind of mowing height adjusting mechanism of mower.
Background technology
Mower is widely used in urban afforestation and park and garden design, and using more is pruning to the lawn, and it generally comprises five parts: engine, running gear, blade, handrail and control section.Its operation principle roughly is: the output shaft at engine is equipped with blade, and High Rotation Speed after the launched machine of blade drives is pruned the lawn.
The mowing height of mower is to determine according to the distance between blade and the ground, because the blade of mower is installed between the front and back wheel, and the casing of mower is integral type, and this just requires the mowing height adjusting mechanism of mower should have following characteristics: front and back wheel must be regulated simultaneously and should be kept blade parallel to the ground as far as possible; Regulate should be able to be firm behind the height fixing; Governor motion should be simple in structure, easy to operate.Initial mower height adjusting method is the front and back wheel of changing different-diameter, obvious this method is inconvenient operation in use, drag-line pulling eccentric wheel appears in the later stage, make front and back wheel change eccentric position, thereby change the height between wheel and the ground, this method can not be fixed after regulating the position preferably, also there are some producers and patent documentation to disclose and utilize linkage to regulate the method for wheel height, but, it generally all is to utilize joystick pulling connecting rod, the eccentric shaft that makes the connecting rod pulling connect two front-wheels and trailing wheel rotates, wheel is moved up and down, and there is following problem in this connected mode: 1, the eccentric shaft that connects wheel may be lower than the line of centres of two front-wheels (or trailing wheel), at this moment, fulcrum will touch ground not flat miscellany, can have a strong impact on travelling and the trafficability characteristic of mower; 2, do not cut off the grass or cut off after broken grass can become entangled on the fulcrum, can increase the running resistance of mower.
A kind of cutting height-adjustment device of grass of mower is disclosed in patent (CN 2838240Y), it comprises and can prop up axle system around the front-wheel that front axle swings, can prop up axle system and heighten handle system around the trailing wheel that hind axle swings, heighten handle system and front-wheel props up axle system, trailing wheel props up and is provided with transmission system between the axle system, although this structure all has been arranged on each connecting rod the inside of casing, make attractive in appearance of mower clean and tidy, but front-wheel fulcrum and trailing wheel fulcrum swing around front axle and hind axle respectively, when swinging to a certain position, front-wheel fulcrum and trailing wheel fulcrum can be lower than the line of centres of wheel, at this moment fulcrum will affect trafficability characteristic and the travelling of mower, but also can bring larger resistance to the operator.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, a kind of mowing height adjusting mechanism of mower is provided, and technical problem to be solved in the utility model is the running resistance that does not increase mower under can the prerequisite of front and back wheel adjusted in concert mowing height.
The purpose of this utility model can realize by following technical proposal: a kind of mowing height adjusting mechanism of mower, mower comprises casing and is arranged on two front-wheels and two trailing wheels of casing lower end, the core wheel place of each front-wheel all be plugged with one can with front-wheel front axle in relative rotation, the core wheel place of each trailing wheel all be plugged with one can with trailing wheel hind axle in relative rotation, it is characterized in that, this governor motion comprises front-wheel fulcrum and the trailing wheel fulcrum that is connected with casing, the two ends of described front-wheel fulcrum respectively are hinged with one can be around the front-wheel swing arm of front-wheel fulcrum rotation, described front axle is connected in the front-wheel swing arm, the two ends of described trailing wheel fulcrum respectively are hinged with one can be around the trailing wheel swing arm of trailing wheel fulcrum rotation, described hind axle is connected in the trailing wheel swing arm, also be hinged with a connecting rod that the power between can be transmitted mutually between described front-wheel swing arm and the trailing wheel swing arm, described trailing wheel swing arm or front-wheel swing arm and a regulating handle are connected.
Operation principle of the present utility model is: front-wheel fulcrum and trailing wheel fulcrum in this mowing height adjusting mechanism for mower are fixed on the casing, be hinged with a connecting rod between front-wheel swing arm and the trailing wheel swing arm, at front-wheel swing arm or the trailing wheel swing arm regulating handle that is connected, the pulling regulating handle makes front-wheel swing arm or trailing wheel swing arm rotate around front-wheel fulcrum or trailing wheel fulcrum, wheel shaft and wheel that swing arm that then is pulled is corresponding just rotate around fulcrum, and spurring another wheel, connecting rod rotates simultaneously, this has just realized the adjusted in concert of mower height, and front-wheel fulcrum and trailing wheel fulcrum all can not move with the rotation of regulating handle, makes fulcrum can not increase the running resistance of mower.
In the mowing height adjusting mechanism of above-mentioned a kind of mower, the middle part of described front-wheel swing arm and front-wheel fulcrum are hinged, and an end and the front axle of described front-wheel swing arm are connected, the other end and rod hinge connection.The front-wheel fulcrum is fixed on the casing, and it is hinged on the middle part of front-wheel swing arm, not only can self not turn to the running resistance that increases mower with lower position, ground, and itself larger distance be arranged overhead, can not cause larger resistance to travelling of mower.
In the mowing height adjusting mechanism of above-mentioned a kind of mower, the middle part of described trailing wheel swing arm and rod hinge connection, an end and the hind axle of described trailing wheel swing arm are connected, and the other end and trailing wheel fulcrum are hinged.The trailing wheel fulcrum is fixed on the casing, and it is hinged on the middle part of trailing wheel swing arm, not only can self not turn to the running resistance that increases mower with lower position, ground, and itself larger distance be arranged overhead, can not cause larger resistance to travelling of mower.
In the mowing height adjusting mechanism of above-mentioned a kind of mower, one end and the trailing wheel swing arm of described regulating handle are connected, the other end can with the clamping of a sour jujube dish, described regulating handle also is connected with an end of an extension spring, the other end and the casing of described extension spring are connected.The draw-in groove that even setting is arranged on the sour jujube dish, and have extension spring to be connected between handle and the casing can be fixed on handle in the deserved draw-in groove after regulating mowing height, thereby fixing the mowing height of mower is fixed; Regulating handle is longer, and stretches to the mower handrail place, and this can transfer the operating personnel easily, and can regulate in motion, need not to squat down or mower cuts out.
In the mowing height adjusting mechanism of above-mentioned a kind of mower, described front-wheel fulcrum is on the front-wheel line of centres, and described trailing wheel fulcrum is on the trailing wheel line of centres.Front-wheel fulcrum and trailing wheel fulcrum all overhead have larger distance, make this fulcrum vertical with the mower travel direction can not increase the running resistance of mower.
In the mowing height adjusting mechanism of above-mentioned a kind of mower, mouth is dodged at the middle part of described front-wheel fulcrum upwards one of bent tabs formation.Be provided with the bending of dodging grass at the front-wheel fulcrum, this can prevent grass overwhelmed by the front-wheel fulcrum or promote after can not be cut by mower blade preferably, thereby affect the mowing quality.
Compared with prior art, the utlity model has following advantage:
