Description

Fruit tree trimmer {A fruit tree trimmer}

The present invention relates to a fruit tree trimmer, and more particularly, by adopting a structure that allows the trimmer part and the electric part to be separated and coupled in a detachable manner to provide ease of maintenance and workability, and to facilitate the coupling. It is about a fruit tree trimmer (red fruit machine) that strengthens product competitiveness, such as improving the trimmer function according to reliable power transmission through structural improvement to ensure that It is a one-touch type fruit tree trimmer that improves the cause of the same work failure.

In general, for pruning various crops or trees for fruit trees, landscaping, forestry, and flowers, pruning means such as pruning shears, pruning saws, knives or trimmers are used.

In general, pruning is performed at appropriate intervals during pruning. If working early, pruning can be performed before flowers bloom, but red pruning is usually performed when fruits start running.

Conventional pruning shears or fruit tree trimmers simply depend only on the manpower of the worker, so it takes a lot of time to work, and the repetitive work increases the fatigue of the worker and inevitably reduces the work efficiency.

For example, fruit trees such as viticulture work standing all year round, and pruning and pruning are repetitive tasks for a long time, which puts a strain on the neck, shoulders, hands, and wrists, and easily causes musculoskeletal disorders.

In particular, grape pruning is a manual operation of the upper extremities, and the rate of complaints of hand and wrist pain due to repetitive hand movements was as high as 41.6%.

Many cases of damage caused by manual work occur in non-automated facility sites.

In the case of the United States, the incidence rate of injuries and diseases per 100 workers in 2001 was 5.7 cases per 100 workers in the entire industry, but 8.1 cases were relatively high for manufacturers where most of the work was done manually.

In addition, 216,400 cases, or 65% of all workplace diseases, are related to repetitive manual work.

Damage in manual work is closely related to the structure of hand tools, and in many workplaces, work is carried out using hand tools designed to be easy and efficient to use.

Nevertheless, many workers are exposed to musculoskeletal disorders due to the use of hand tools, and they complain of pain mainly in areas related to muscles, tendons, and nerves.

One of the causes of hand-related disorders is repetition.

Repetitive upper extremity movement is the most important risk factor for developing cumulative traumatic injury.

Cumulative traumatic injury related to excessive repetition has a high incidence rate in industries or jobs that repeatedly use hand tools, and the cause is due to improper design of tools.

The generally known and recommended hand tool design should fit the shape of the hand and keep the hand ink as straight as possible, and it is desirable to design it as a tool that uses the entire finger to hold it.

On the other hand, frequent wrist movements and work in an inappropriate wrist posture are closely related to upper extremity work-related musculoskeletal disorders.

As for the pressure of the hand on the hand tool, if the handle of the hand tool touches the pressure-sensitive part and puts pressure on nerves and blood vessels, it causes pain and obstructs blood flow. It is preferable to be

In order to improve the above, it is intended to reduce the fatigue of fingers and wrists due to the grape picking operation and ultimately to prevent musculoskeletal disorders such as cumulative traumatic disorders that can occur with a simple repetitive operation on the upper extremity.

There are electric scissors or fruit tree trimmers for viticulture, which have recently increased the workload on farms.

In this regard, many devices related to electric scissors or fruit tree trimmers operating based on the driving force of the motor are being released.

The scissors blade of these electric scissors is composed of a fixed blade fixed to the main body and a movable blade capable of repeatedly moving a predetermined section around a rotational shaft formed on the fixed blade to perform the work.

In recent years, portable electric scissors that are easy to handle and can be used continuously for a certain period of time have been released, and the preference for them is increasing, and there is a trend toward miniaturization and weight reduction of electric scissors or fruit tree trimmers.

However, the conventional fruit tree trimmer has a problem in that, since the electric part and the trimmer part are formed by rotational detachment, there are many difficulties in maintenance such as failure during use or replacement of the trimmer.
