Problems solved by technology

[0003] And existing lawn mower, when weeding, when using low-power lawn mower, the rotating speed of motor is less, if grass or other vegetation are more dense in the lawn, the impeller of lawn mower is because rotating speed is less, and power is insufficient. The mowing efficiency is low, and when there is a large resistance when mowing, there is a machine jam, which will cause heat and damage the mowing device; when using a high-power mower, the motor speed is relatively high, due to the dense lawn The area of ​​the mower is small, there is a waste of energy, and when the impeller speed of the lawn mower is too high, the staff is prone to fatigue

Embodiment 1

[0042] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0043] A lawnmower provided by the present invention includes a DC generator, a storage battery, a current control device, a controller, a lawn mowing device, a current detection device and a sound measuring device;

[0044] The DC generator is electrically connected to the battery; the battery is connected to the current detection device through the current control device, the current detection device is electrically connected to the mowing equipment, and the current detection device is electrically connected to the DC generator through the controller; The grass equipment includes a drive motor, and the drive motor includes a speed sensor arranged on its output shaft; the speed sensor is electrically connected to the current control device through a controller, and the controller is used to obtain the speed value of the speed sensor, when the speed value is less than the preset speed threshold, inc...

Embodiment 2

[0048] The difference between the second embodiment and the first embodiment is that a lawn mower further includes an impeller, a coupling, a switch, a humidity sensor and a temperature sensor.

[0049] The impeller includes a power shaft and blades connected to the power shaft;

[0050] The output shaft is connected with the power shaft through a coupling;

[0051] The current control device is electrically connected to the drive motor through a switch;

[0052] A rotational speed sensor is provided on the power shaft, and the rotational speed sensor on the power shaft and the rotational speed sensor on the drive motor are respectively electrically connected to a switch through a controller, so as to be used as a switch between the rotational speed sensor on the power shaft and the rotational speed sensor on the drive motor. When the difference of the rotational speed is greater than the preset threshold, the controller controls the switch to be disconnected;

[0053] The s...

Abstract

The invention provides a mower. The mower comprises a storage battery, a current control device, a controller and mowing equipment, wherein the storage battery is electrically connected with the mowing equipment through the current control device; the mowing equipment comprises a driving motor, and the driving motor comprises a rotation speed sensor which is arranged on an output shaft of the driving motor; the rotation speed sensor is connected with the current control device through the controller; the controller is used for obtaining a rotation speed value of the rotation speed sensor, and when the rotation speed value is smaller than a preset rotation speed threshold value, the output current of the current control device is increased. The mower has the advantages that the mowing efficiency is high, the output power of the mower can be intelligently adjusted, the rotation speed of the driving motor is adjusted, the waste of energy is avoided, and the energy-saving and environment-friendly effects are realized.

Description

technical field [0001] The invention relates to the field of garden tools, in particular to a lawnmower. Background technique [0002] Lawn mower (Lawn mower) also known as weeder, lawnmower, lawn trimmer, etc., a lawn mower is a mechanical tool for trimming lawns, vegetation, etc., which can be divided into diesel engines and gasoline engines. The mowing impeller of the lawn mower is driven by the motor to rotate at high speed, and the output speed is greatly improved, which saves the working time of the weeding workers and reduces a lot of human resources. In countries where the mechanization of animal husbandry is highly developed, the research on new lawn mowers is developing in the direction of high speed and energy saving. [0003] And existing lawn mower, when weeding, when using low-power lawn mower, the rotating speed of motor is less, if grass or other vegetation are more dense in the lawn, the impeller of lawn mower is because rotating speed is less, and power is...
