Description

An angle-adjustable hedge trimmer

technical field

The utility model relates to a vegetation hedge trimmer, in particular to an angle-adjustable hedge trimmer.

Background technique

Holly is one of the important plants in garden nursery stock greening. It has luxuriant branches and leaves and is evergreen all the year round. Because of its beautiful tree shape and crisp branches, it is the first choice for park fences and road greening, so it is mostly planted in gardens and roads for beautification and greening purposes. It can be applied to parks, gardens, green walls and central medians of expressways. The growth rate of holly is very fast, especially in summer, when the branches and leaves are lush and green, so it brings the problem of regular pruning. At present, holly pruning can only be done by manpower, which is not only time-consuming and labor-intensive, but also has high cost and low efficiency. Gardeners cause a lot of trouble. The cutting surface of the existing hedge trimmers used to trim spherical vegetation is flat, which can be easily trimmed compared to those flat-shaped holly, but when encountering irregular round or oval holly, when pruning It is more cumbersome. Repeated pruning will not only lead to unsightly pruning radians, but also the grass shoulders will fly around during pruning, affecting the ornamental value of vegetation, and it is time-consuming and laborious. This requires the training of most professional holly pruning personnel. So existing holly trimmer also has certain defectives in structure and design.

Hedge trimmers currently on the market have relatively single functions. For example, hedge trimmers can only trim horizontal holly; Hedge trimmers are mainly handheld devices, which still require a lot of manpower to operate. The power comes from motors or gasoline engines, but they are heavy and inconvenient to carry. When pruning special shapes with high requirements, rich operating experience is required and the work efficiency is very low; it can be seen that for heavy holly pruning work, we urgently need a convenient and fast mechanized equipment that integrates horizontal pruning and surface pruning , to improve work efficiency and quality, while ensuring the personal safety of the operator. Pure electric modular design, the electric motor replaces the gasoline engine to provide power, which greatly avoids the noise generated during work, and finally achieves the purpose of harmonious design and harmonious manufacturing. In addition, we conducted a questionnaire survey on the use and demand of sanitation workers and greening tools for sanitation workers and greening tools. Now we summarize the above surveys:

(1) Most sanitation workers hope to use more efficient greening tools;

(2) Some sanitation workers want to use greening tools with more functions;

(3) Most sanitation workers hope to combine holly pruning tools with hedge pruning tools;

(4) Consumers generally hope that they can buy an angle-adjustable hedge trimmer with complete functions.

According to the investigation and analysis, the following conclusions are drawn: the multi-functionalization and automation of an angle-adjustable hedge trimmer has great market potential, but the current technology is not yet mature. Consumers hope to buy a product with high cost performance, strong operability and high intelligence. In the design of an angle-adjustable hedge trimmer, we have added solutions to the above problems to ensure that the product can be recognized by consumers after it is put into the market.
