Description

Knife Front Round Bundle Form Household Mowing Grass Collection Device

technical field

The utility model relates to a device for home lawn maintenance, in particular to a home mowing and collecting device in the form of a round bundle in front of a cutting knife.

Background technique

With the improvement of people's living standards and aesthetic standards, people are increasingly recognizing the role of lawns in landscape layout and accommodation atmosphere. In particular, the process of industrialization has brought serious pollution, so green plants are becoming more and more popular in modern society. Therefore, lawns gradually show great advantages in areas close to urban life such as garden landscapes and community greening, and the number and area of lawns are constantly expanding. At the same time, the daily maintenance of the lawn has become an urgent problem to be solved, and the most tedious and important part is the mowing process.

Proper and timely mowing behavior not only makes the lawn neat and beautiful, but also allows the grass to grow and renew continuously and maintain good vitality. However, due to the continuous increase in the number and area of lawns, the cost of manual mowing is too high, which is not conducive to standardization. The use of lawn mowers can effectively solve these problems.

Lawn mowers play a very active and indispensable role in the maintenance of landscape lawns, family garden lawns, etc. However, on the one hand, the existing lawn mowers are mostly designed for large areas such as farms, so there are problems such as difficult collection of broken grass and need to cooperate with special machinery for follow-up processing, high cost, and scattered functions; on the other hand, traditional lawn mowers use diesel Or gasoline engine as power, factors such as high noise, high risk and non-environmental protection greatly limit the home use of lawn mowers. This urgently requires a lawn mower that is small in size, high in safety, low in noise and can handle broken grass autonomously.
