Problems solved by technology

[0003] Existing lawn mowers generally can only trim the same height during use, or it is more cumbersome to adjust the trimming height, and when the lawn mower is performing positioning operations, it cannot properly mow Placement of the lawn mower will easily cause the overall deflection during the operation process. Therefore, a garden lawn mower mowing height adjustment mechanism is proposed to solve the above problems.

Embodiment 1

[0025] see Figure 1-6 , the present invention provides a technical solution:

[0026] A lawnmower mowing height adjustment mechanism for gardens, including a base 1, a lifting mechanism 3, a lifting box 4 and an adjusting mechanical arm structure 5, the left end of the base 1 is provided with a push handle 8, which is convenient for adjusting The promotion of the base 1, the inner side of the push handle 8 is provided with a positioning structure 9, the inner side of the top of the base 1 is provided with an active mechanism 2, the active mechanism 2 includes a first servo motor 201, a driving gear 202 and a driven gear 203, and the top of the base 1 A lifting mechanism 3 is provided, and the lifting mechanism 3 includes a threaded sleeve 301, a first sliding block 302, a first electro-hydraulic push rod 303, a connecting rod 304, a threaded rod 305, a second sliding block 306 and a second electro-hydraulic push rod 307 , the lifting box 4 is arranged on the top of the secon...

Embodiment 2

[0030] see Figure 1-6 , the present invention provides a technical solution:

[0031] A lawnmower mowing height adjustment mechanism for gardens, the same parts in embodiment 2 as in embodiment 1 will not be repeated in the present invention, and the difference lies in the working process.

[0032] Work flow: the present invention is powered by an external power supply before use, controls the device through the controller 14, starts the third servo motor 12, and makes the third servo motor 12 drive the worm 13 to rotate, and the worm 13 will pass through the worm wheel after rotation. The engagement of the groove 508 drives the main arm 501 to rotate, so that the angle of the main arm 501 can be changed. After the main arm 501 rotates, it will drive the height of the adjustment seat 504 to lift, so that the height of the electric telescopic rod 6 and the mower 7 can be adjusted. Adjustment, the self-locking of the second servo motor 507 makes the third bevel gear 506 rotate...

Abstract

The invention relates to the technical field of mowers, in particular to a mowing height adjusting mechanism for a garden mower. The mowing height adjusting mechanism comprises a base, a lifting mechanism, a lifting box and an adjusting mechanical arm structure, wherein a positioning structure is arranged on the inner side of a pushing handle, a driving mechanism is arranged on the inner side of the top end of the base, and the lifting mechanism is arranged at the top end of the base; and the adjusting mechanical arm structure is arranged at the right end of the lifting box, an electric telescopic rod is fixedly connected to the bottom end of the adjusting mechanical arm structure, and a mowing device is fixedly connected to the bottom end of the electric telescopic rod. The driving mechanism and the lifting mechanism are arranged, so that the height of the lifting mechanism can be increased through operation of the driving mechanism; the height of the lifting box is adjusted, so thatthe adjusting mechanical arm structure drives the electric telescopic rod and the mowing device to adjust the height, the mowing height of the mowing device can be adjusted when the mowing device is used for mowing grass and trees, and the grass and trees with different heights can be conveniently mowed.

Description

technical field [0001] The invention relates to the technical field of lawnmowers, in particular to a mowing height adjustment mechanism for garden lawnmowers. Background technique [0002] A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. It basically consists of a mowing device set on the frame, and the mower is fed by people in the form of pushing, and the grass will follow With the crazy growth of time, the lawn mower plays an extremely important role. Therefore, the demand for a lawn mower mowing height adjustment mechanism for gardens is increasing. [0003] Existing lawn mowers generally can only trim the same height during use, or it is more cumbersome to adjust the trimming height, and when the lawn mower is performing positioning operations, it cannot properly mow The placement of the lawn mower is easy to cause the overall deflection during the operation. Therefore, a lawn mower mowing height adjustment mechanism for gardens is proposed to so...
