Abstract
The utility model discloses an intelligent variable-speed grass trimmer with a rear-mounted motor. The intelligent variable-speed grass trimmer comprises a trimmer housing, the motor disposed inside the trimmer housing, and a constant-power soft starter. A handle is arranged at the lower end of the trimmer housing. A switch is disposed on the handle. The switch, the motor and the constant-power soft starter are fitly connected through wires. A flexible shaft is mounted on the motor. The flexible shaft penetrating the trimmer housing is connected with a shaft connector. A cutting device is disposed on the shaft connector. Operating noise of the intelligent variable-speed grass trimmer according to the technical scheme can be effectively controlled under safety regulations when the trimmer idles.
Description
Technical field
The utility model relates to a kind of intelligent speed changing grass pruning machine with rear-mounted motor.
Background technology
Mower is a kind of widely used electric garden tool, and because operating efficiency is high, lightweight, volume is little, easy to carry, and consumer's rear love extremely, the huge market demand.Mower is in the market mostly following two kinds of structures: the one, and adopt motor directly to export, no-load speed higher (10000RPM/MIN) noise is larger; The 2nd, adopt motor gear speed changing structure.Though can be effectively by low noise, cost is higher, and assembling is more complicated.
Summary of the invention
When the technical problems to be solved in the utility model is to provide a kind of unloaded operation, the mower of low noise.
For solving technique scheme, the utility model adopts following technical scheme:
A kind of intelligent speed changing grass pruning machine with rear-mounted motor, comprise mower casing, and be arranged on motor and the permanent merit soft starting device in mower casing, described mower casing lower end is formed with lever, on described lever, be provided with switch, described switch, motor and permanent merit soft starting device are connected by lead-in wire, on described motor, are mounted with flexible axle, this flexible axle is connected with shaft coupling through mower casing, and described shaft coupling is provided with cutting equipment.
The utility model is as preferred technical scheme, and described motor is variable speed motor.
Beneficial effect
The rotating speed (6000/MIN in) of permanent merit soft starting device by no-load current (< 2.5A) control motor now can be effectively by noise control in 80dB.When work, the power rising of motor when cutting equipment contact with grass, this electric current by permanent merit soft starting device is understood > 2.5A, and circuit now can be decontroled completely, because the rotating speed of motor under duty now can be less than no-load speed.Noise now will be far smaller than below the 96dB of security regulations.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
Refer to shown in Fig. 1, a kind of intelligent speed changing grass pruning machine with rear-mounted motor, comprise mower casing 1, and being arranged on the motor 2 and permanent merit soft starting device 3 in mower casing 1, described mower casing 1 lower end is formed with lever 4, on described lever 4, is provided with switch 5, described switch 5, motor 2 are connected by lead-in wire with permanent merit soft starting device 3, on described motor 2, be mounted with flexible axle 6, this flexible axle 6 is connected with shaft coupling 7 through mower casing 1, and described shaft coupling 7 is provided with cutting equipment 8.
Described motor 2 is variable speed motor.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
Claims (2)
1. an intelligent speed changing grass pruning machine with rear-mounted motor, it is characterized in that: comprise mower casing, and be arranged on motor and the permanent merit soft starting device in mower casing, described mower casing lower end is formed with lever, on described lever, be provided with switch, described switch, motor and permanent merit soft starting device are connected by lead-in wire, on described motor, are mounted with flexible axle, this flexible axle is connected with shaft coupling through mower casing, and described shaft coupling is provided with cutting equipment.
2. intelligent speed changing grass pruning machine with rear-mounted motor according to claim 1, is characterized in that: described motor is variable speed motor.
