Energy-saving mower capable of protecting blade and using method of energy-saving mower

Abstract

The invention discloses an energy-saving mower capable of protecting a blade and a using method thereof, and belongs to the field of garden electric tools. The energy-saving mower capable of protecting the blade comprises a mower body, the mower body comprises a main mounting frame, a variable-speed motor is mounted on the side wall of the upper end of the main mounting frame, and the output end of the variable-speed motor is connected with a driving shaft; and a friction sleeve is fixedly connected to the inner wall of the upper end of the main mounting frame, the driving shaft penetrates through the friction sleeve, blades are retracted into a mounting disc to be protected, the blades extend out through centrifugal force in the working process to cut grass, lubricating cotton smears blade protection oil on the two faces of each blade, the blades are prevented from being rusted, in addition, friction heat is generated by additionally arranging the friction sleeve, so that a memory metal supporting rod is subjected to phase change, polishing of the blades is achieved, the sharpness of the blades is kept, and compared with the prior art, self-protection and self-repairing of the blades can be achieved.

Description

technical field [0001] The invention relates to the field of garden electric tools, and more specifically relates to an energy-saving lawn mower capable of protecting blades and a use method thereof. Background technique [0002] The development of agricultural mechanization, the improvement of work efficiency, and the improvement of agricultural production efficiency are very important in a large agricultural country like ours. As a tool that plays an important role in agricultural production, the lawn mower has the most direct impact on the output of crops. Its invention is human A great advance in civilization. Lawn mowers are also called weeders, lawnmowers, lawn trimmers, etc. The lawn mower is a mechanical tool for trimming lawns, vegetation, etc., and can be divided into diesel engines and gasoline engines. It is composed of cutter head, engine, traveling wheel, traveling mechanism, blade, handrail, control and other parts. The blade utilizes the high-speed rotation...

AI Technical Summary

Problems solved by technology

[0003] The blades of existing lawn mowers are all exposed to the external environment. The water droplets on the grass and the air can easily cause the blades to rust, and the blades will touch the soil during the mowing process, causing the soil to adhere to the blades Further deepen the rust. In addition, due to the grassland environment, uneven terrain and human operation, the blade will inevitably hit small stones or branches in the soil, making the blade dull and greatly reducing the service life of the blade. Very troublesome and inconvenient to maintain
