Abstract
The utility model relates to a mowing knife with a height adjustment mechanism and a corresponding mower. The existing knife of a mower is provided with a height adjustment device. The device has too complicated structure and is not convenient to assemble and adjust; and the device does not have the display function and can estimate the adjustment height only. Therefore, the mowing knife with the height adjustment mechanism comprises a lead screw and a nut. The mowing knife is characterized in that the nut is fixed and can be rotated; the lead screw is provided with an upright guide mechanism; the inner part of the lead screw is a hollow; and a mowing motor can be assembled and matched with the lead screw. By the design, after the mowing knife is assembled on the mower, the nut only needs to be turned so as to conveniently adjust the height of a blade; the mowing motor is matched, so that the mowing knife can move upward and downward synchronously; and no complicated spline structure is needed. The utility model also relates to the corresponding mower. The mowing knife with the height adjustment mechanism has the advantages that the structure is simple, and the adjustment is convenient; the scale display can be seen when the mowing height is adjusted; and the assembled mower is suitable for trimming various lawns.

The utility model content
The technical problems to be solved in the utility model is the above-mentioned defective that how to overcome prior art, and a kind of mowing cutter height adjustment mechanism simple in structure, easy to adjust and corresponding mower are provided.
For solving the problems of the technologies described above, this mowing cutter height adjustment mechanism comprises leading screw and screw, it is characterized in that: described screw is fixed, and rotatable, and described leading screw is provided with vertical guiding mechanism, its inner hollow, and the blade drive motors can be installed.So design, be installed on the mower after, as long as rotate screw, just can regulate blade height easily, the blade drive motors moves up and down synchronously, does not need the spline structure of complexity.
As optimization, described vertical guiding mechanism comprises three leads, and three leads are evenly distributed on around the leading screw, and be fixed on the chassis, be fixed with leading truck on the described leading screw, have three pilot holes on this leading truck, described lead passes a pilot hole respectively.So design, guide frame is simple, easy to assembly, stress equalization.
As optimization, described lead upper end is fixed with a retainer plate, also is provided with a platen on this retainer plate, and described screw excircle is provided with a circle bulge loop, and this bulge loop is clamped between retainer plate and the platen.So design is simple in structure, easy to assembly.
As optimization, described platen top has centre bore, axle center, described screw top is fixed with an external gear, this external gear center is provided with a knob, the external gear outside also is with the internal gear of a concentric, also be provided with two gears on the platen between internal gear and the external gear, two gears are symmetrically distributed in the centre bore both sides, and each gear meshes with internal gear, external gear simultaneously, also being provided with scale on the described internal gear outer rim shows, form dial, the mowing cutter height that different scales are corresponding different.So design, the turn knob, screw together rotates together with the external gear in its axle center, and two gears of drive and its engagement, these two gears further drive internal gear and rotate, and the dial on the internal gear is also in company with rotation, thus the generation Presentation Function.
As optimization, it also comprises the cutter cover, and this cutter cover is fixed on the leading screw bottom, and is positioned at the top of blade.So design, when regulating blade height, blade and the same moved further of cutter cover, the gap between the two can not change.
This mower comprises shell, running gear and mowing system, wherein mowing system comprises blade drive motors and blade, it is characterized in that: described mowing system also comprises the described mowing cutter of claim 1 height adjustment mechanism, described blade drive motors just is installed in the described leading screw, its output shaft stretches out leading screw downwards, and described blade just is fixed on the output shaft of blade drive motors.
The utility model mowing cutter height adjustment mechanism has advantage simple in structure, easy to adjust, can see simultaneously when height is mowed in adjusting that scale shows, with the various lawns of the suitable pruning of the mower of its assembling.
