Noise-free cryogenic mower

Abstract

The invention discloses a noise-free cryogenic mower and relates to the technical field of living devices. The noise-free cryogenic mower includes a square shaped installation frame. The left and right two sides of the installation frame are all provided with wheels. The rear of the installation frame is provided with a handrail. The interior of the installation frame is provided with a cryogenicmowing device. The cryogenic mowing device includes a thermal insulation box. Liquid nitrogen is preserved in the thermal insulation box. The bottom wall of the thermal insulation box is a heat conducting plate. The middle of the upper end of the thermal insulation box is connected with a funnel. The top of the funnel is below the top of a protective frame. The outer side of the thermal insulationbox is fixedly connected with a square shaped protective frame in sleeve. The protective frame is connected with the interior of the installation frame by sliding up and down. The left and right twoends of the installation frame are all provided with puller bolts in thread. The noise-free cryogenic mower has the advantages of using extremely low temperature to cause irreversible freezing and brittleness of plant stems and leaves and achieving the mowing effect, low cost and no noise without causing dust raising.

Description

technical field [0001] The invention relates to the technical field of landscaping devices. Background technique [0002] In daily life, it is common to use a lawn mower to correct the lawn during the growth of the lawn to avoid excessive growth. Traditional lawn mowers use high-speed rotating mowing discs to mow the grass, and there are many problems, such as: very noisy Large, high-speed rotation and heavy machine itself cause very loud noise, which is difficult to eliminate, especially in living areas or campuses, where the noise has a serious impact; at the same time, high-speed rotation also causes grass blades and dust to fly, affecting The surrounding breathing environment and the working environment of lawn mowers are relatively harsh. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-temperature lawnmower without noise in view of the above technical deficiencies. Using extremely low temperature to ...
