Description

A kind of motor-driven brush saw

【Technical field】

The present invention relates to brush cutter technical field, and in particular to a kind of motor-driven brush saw.

【Background technology】

Brush cutter be it is a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., compare it is manual use reaping hook etc. to mow, mow Machine saves the activity duration of weeding workman, reduces substantial amounts of human resourcess.In existing brush cutter, there is cart type brush cutter And knapsack type brush cutter, and have gasoline type and electrodynamic type.The brush cutter pollution of gasoline type is big, and noise is also big, and its structure can be led Cause gasoline combustion not exclusively, cause the wasting of resources；DYN dynamic brush cutter is portable, simple to operate, and working environment flexibly, is carried on the back The motor-driven brush saw of negative formula is more welcome by the vast farmerses masses.But between two handles of existing back-pack electric brush cutter Distance be all changeless, be unfavorable for that arm opens up the use of different people, while there is also a defect, be only provided with one Switch, and switch the position for arranging and be easy to be touched by other objects, if accidentally encountering switch, will start and start Machine, and then the rotation of cutting blade is driven, easily cause the generation of contingency.How motor-driven brush saw is avoided in inoperative shape How accidental activation under state, ensure the comfort level that people operationally wait, and has become topic of concern.

【The content of the invention】

It is an object of the invention to：For the problem of accidental activation under the easy off working state of motor-driven brush saw, there is provided one The motor-driven brush saw with safety switch is planted, the accidental activation problem under off working state will not be occurred, and be can adjust two handss The distance between handle, more hommization.

To achieve these goals, the technical solution used in the present invention is as follows：

A kind of motor-driven brush saw, including electromotor, connecting rod and cutting blade；The electromotor and the cutting blade point Not She Yu the connecting rod opposite end；The electromotor is by the power transmission shaft inside the connecting rod and the cutting Blade connects；The engine housing is provided with the Wiring port of power supply source wire terminal insertion；The shell of the electromotor is arranged There is a first handle, the first handle is internally provided with a microprocessor, and the lateral wall of the first handle is provided with one The groove that individual available slip lid is covered, is provided with controlling switch and safety switch, the peace space outside of the first handle Full switch is located in the groove；The Wiring port is electrically connected with the safety switch, and the safety switch is micro- with described Processor is connected by electronic circuit, and the microprocessor is connected by electronic circuit with the controlling switch, and the control is opened Close and be electrically connected with the electromotor；Second handle and grass guard, the second handle are arranged at intervals with the connecting rod also With the connecting rod by snapping connection and being located between the first handle and the grass guard, the grass guard and the company Extension bar is fixedly connected by change.

Know-why：External power source is powered, and electromotor drives cutting blade rotation by power transmission shaft, can carry out cutting work Make；Safety switch, microprocessor and controlling switch constitute a protection system, only when safety switch and controlling switch simultaneously During unlatching, electromotor could work, and when under working condition, controlling switch disconnects, safety switch also and then disconnects, and restarting is sent out Motivation needs to restart safety switch and controlling switch, and starting safety switch needs to open the slip lid of a groove, it is to avoid The accidental activation of electromotor causes the generation of security incident；Second handle is snapped connection with connecting rod, can be according to user Physical qualification it is different, adjust the distance between first handle and second handle, increased the comfort level during work of user.

In the present invention, it is preferred that described also to include power line and power supply module, connect described in one end connection of the power line Line end mouth, the other end of the power line connect the power supply module.Operating for the motor-driven brush saw provides energy, power supply Component is storage battery.

In the present invention, it is preferred that the controlling switch is provided with one grade and two grades, to adjust the rotating speed of the electromotor, enters And adjust the rotating speed of the cutting blade.The rotating speed of electromotor according to requirements of one's work, can be adjusted, and then adjusts cutting blade Rotating speed, improves cutting speed, time-consuming.

In the present invention, it is preferred that the material of the first handle, second handle and grass guard is plastics, described second Anti-skidding raised line is provided with handle.The setting of anti-skidding raised line meets human body stress, increases the comfort level of work.

In the present invention, it is preferred that the material of the connecting rod is rustless steel or aluminium alloy.Connecting rod made by rustless steel Bonding strength is can ensure that, powerful electromotor is equipped with, it is ensured that the service life of connecting rod；Connecting rod made by aluminium alloy, Quality is light and handy, in the case where ensureing that cutting work can be smoothly completed, can reduce heavy burden, mitigate the burden of user.

In the present invention, it is preferred that the cutting blade is in a word blade or three teeth cutter blades or circular saw blade Kind, and material is 65 manganese steel.Cutting efficiency can be improved according to the different blades of the different replacings of the object of cutting, it is time-consuming Save energy；Meanwhile, cutting blade made by 65 manganese steel is sharp, wear-resisting, superior performance, improves the use longevity of cutting blade Life.

In the present invention, it is preferred that the grass guard is in arc-shaped.The design of circular arc meets what the grass after cutting was spilled over Direction, better ensures that the safety of user.

In sum, as a result of above-mentioned technical proposal, the invention has the beneficial effects as follows：

1st, motor-driven brush saw simple structure of the present invention, easy to operate, and using storage battery energy supply, working environment flexibly, has effect For different terrain, oily formula brush cutter is compared, noise is little, pollution-free, gone out easy to carry, without the need for band gasoline, alleviate heavy burden； Small stems of all kinds of crops, weeds and tree etc. can be cut, save manpower, improve work efficiency, embody agriculture The benefit brought to agricultural production with apparatus.

2nd, the safety switch of motor-driven brush saw of the present invention, microprocessor and controlling switch constitute a protection system, need Safety switch is opened simultaneously and controlling switch electromotor could operate, and safety switch is arranged on a groove with slip lid The inside, it is ensured that safety switch will not be opened because foreign object is touched, and effectively prevent the peace that electromotor is caused because of accidental activation Full accident, it is more safe and reliable；Second handle allows second handle to adjust in connecting rod with snapping connection for connecting rod Position, can be adjusted to the position that allows people to feel the most comfortable, embody hommization according to the demand of user；Controlling switch sets One grade and two grades is equipped with, different power is equipped with according to practical situation, work efficiency can be improved, electricity can be also saved, while It is more safe and reliable.
