Combined lawn trimmer dislocated knife

Abstract

The invention pertains to garden machinery fabrication field, especially a combined dislocation knife of lawn trimmer, which comprises a shaft, a shaft sleeve, keys, screws, washers, bolts, cutting blades, bevel fan blades, static blades, a hanging board, stud bolts and so on. A petrol engine or a motor drives the cutting blades to rotate; the cutting blades are dislocated with the static blades so as to form a shearing mechanism to shear grass; the bevel fan blades or centrifuge blades rotates to cast the sheared grass up to grass collection bag through a helical case. The invention has evident energy-saving effect, so a motor is preferably used as the power source; the electric lawn trimmer with a battery can work anywhere outdoor. Because of good obstacle-resistant performance, the invention is more suitable for trimming lawn in our country. The invention also has advantages of environmental protection and energy-saving, and extensive use future.

Description

1. Technical field [0001] The invention belongs to the field of garden machinery manufacturing, in particular to a combined lawn mower dislocation knife. 2. Background technology [0002] At present, in order to purify the air, beautify the environment, and provide a good environment suitable for modern people's life and work, various cities have set up many lawns according to local conditions. At the same time, lawn machines have also emerged as the times require. At present, lawn mowers on the market are powered by internal combustion engines, mainly imported two-stroke air-cooled gasoline engines, equipped with hand throttle casings, blades, walking wheels, handles, height adjustment devices, straw bags, and some with There is a variable speed clutch and self-propelled device. The gasoline engine drives the inclined-plane blade to rotate, and the lower part of the casing generates suction, and the cut grass is blown into the straw bale through the outlet of the upper par...

AI Technical Summary

Problems solved by technology

In addition, the swinging knife will collide with the cut grass during the rotation process and disrupt the cut grass. This process wastes the most kinetic energy, and this process is redundant and has no necessary functions.

During the rotation of the knife, it collides with the cut grass, and a lot of kinetic energy is absorbed and wasted by the cut grass
