Abstract
The invention relates to a grass trimmer with a height-adjustable blade. The grass trimmer with the height-adjustable blade comprises a support, a motor with a power output shaft extending downwards and an installment seat arranged at the bottom of the motor, wherein the support is provided with a positioning pin, and the installment seat capable of sliding along the positioning pin up and down is arranged on the support. The grass trimmer with the height-adjustable blade further comprises a first cam, wherein the first cam is rotably fixed on the support, the forwards-protruded outline curve portion of the first cam abuts against the bottom surface of the installment seat, teeth are arranged on the rear portion of the first cam, the power output shaft is provided with a drive gear, and the drive gear is connected with the teeth on the rear portion of the first cam through a clutch. The installment seat can be raised or lowered through controlling of the rotating direction of the cam, and therefore the purpose that the height of the motor and the height of the blade are simultaneously adjusted is achieved. Compared with a single cam, a second cam is arranged to provide more stable and more reliable raising force for an installment plate.
Description
Technical field
The present invention relates to a kind of mower, be specifically related to the adjustable mower of a kind of blade height.
Background technology
The height of existing mower blade is regulated to be first removal of inserts substantially and then the mode that blade is installed to differing heights is realized.This method can not be adjusted blade height immediately, can only regulate by the mode of dismounting blade in the mower stopped status.
Summary of the invention
The technical problem to be solved in the present invention is: propose the mower that a kind of blade height can be adjusted immediately.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: the adjustable mower of a kind of blade height, comprise support, motor and the mount pad of being located at described motor bottom with power take-off of downward extension, it is characterized in that: described support is provided with alignment pin, described mount pad can be along on the described alignment pin, being arranged on the described support of lower slider, also comprise first cam, described first cam is rotating to be fixed on the described support, and the lordosis profile curved portion of described first cam is tight against on the bottom surface of described mount pad, the rear portion of described first cam is provided with tooth, described power take-off is provided with driven wheel, and described driven wheel engages by the tooth of clutch with the described first cam rear portion.
Further, also comprise second cam that drives and rotate synchronously with described first cam by connecting rod, the lordosis profile curved portion of described second cam also is tight against on the bottom surface of described mount pad.
The invention has the beneficial effects as follows:
The present invention raises by the rotation direction of control cam and puts end mount pad, thereby regulates the motor height and reach the purpose of regulating blade height simultaneously.The purpose that second cam is set is that single relatively cam can provide a more stable and more reliable lifting power to installing plate.
Description of drawings
Below in conjunction with accompanying drawing to the adjustable mower of blade height of the present invention.
Fig. 1 is the schematic diagram of the structure of the adjustable mower of blade height among the present invention.
Embodiment
Embodiment
According to shown in Figure 1, the present invention includes support 1, have motor 3, first cam 4, second cam 5 of the power take-off of downward extension and be located at the mount pad 6 of described motor 3 bottoms.
Have horizontally disposed driving rotating shaft 8, the first cams 4 on the support 1 and be socketed in and drive in the rotating shaft 8 and under the driving of driving shaft 8, can rotate at support 1, and the lordosis profile curved portion of first cam 4 is tight against on the bottom surface of mount pad 6.
The present invention raises by the rotation direction of control cam and puts end mount pad, thereby regulates motor 3 height and reach the purpose of regulating blade 9 height simultaneously.The purpose that second cam 5 is set is that single relatively cam can provide a more stable and more reliable lifting power to installing plate 6.
The above-described embodiment that is not limited to of the present invention, all employings are equal to replaces the technical scheme that forms, and all drops in the protection domain of requirement of the present invention.
