Machine shell structure with air inlet compensation function and mower

Abstract

The invention discloses a machine shell structure with an air inlet compensation function. The machine shell structure comprises a machine shell main body and air inlet units, wherein a cavity is formed in the machine shell main body in a penetrating manner, and the machine shell main body comprises a connecting surface and a working surface which are oppositely arranged; and the multiple air inlet units are arranged around the machine shell main body, and air outlets of the air inlet units are located in the end close to the working surface. According to a mower with the machine shell structure, more air inflow can be achieved in the mowing process at a low gear (close to the ground), the total flow of air at a grass outlet of the mower and the air outflow are increased due to the increase of the air inflow at the bottom, air flowing of a motor is accelerated due to the siphonage phenomenon, heat dissipation of the motor is improved, meanwhile, the utilization rate of the volume of the grass frame is increased, and the frequency of cleaning the grass frame by an operator in the using process is reduced.

Description

technical field [0001] The invention relates to the field of weeding mechanical equipment, in particular to a casing structure with air intake compensation and a lawnmower. Background technique [0002] Lawnmower is a kind of most commonly used garden tool, and it uses motor and engine as driving device, drives cutting part to cut and collect operation for grass. The rotating blade of the lawn mower first cuts the grass, and secondly, the blade has a certain curved angle. During the rotation process, it can play the role of a fan. When cutting the grass, the grass can be discharged from the casing by air flow and thrown into the In the collection box, because the lawn mower needs to cut grass of different heights during use, the current lawn mower usually has a mowing height adjustment function. When it is lowered to a certain height, the height of the bottom of the lawn mower casing will When the height of the lawn mower is lower than the actual grass or even level with th...

Problems solved by technology

[0004] However, the structure in Patent Document 1 needs to be used with a blower, which requires a large installation space. At the same time, it does not solve the problem that it is difficult to replenish air at the bottom when the casing is attached to the ground (the blade is close to the ground), and it is not very good. Solve the problem of mowing efficiency and forage collection
