Abstract
An automatic moving snow removal device including a moving module, driving a snow blower to move; a working module, including a working motor and a snow throwing mechanism driven by the working motor, the snow throwing mechanism is driven by the working motor to collect accumulated snow and inclusions on the ground and throw out of the snow throwing mechanism; and a control module, configured to control a rotary speed of the working motor to cause a speed when the inclusions depart from the snow throwing mechanism is not higher than 41 m/s.
Claims20
An automatic moving snow removal device, comprising:
- a moving module driving the automatic moving snow removal device to move;
- a working motor having a rotary speed;
- a snow throwing mechanism driven by the working motor to collect and throw accumulated snow and inclusions on the ground out of the snow throwing mechanism in a plurality of snow throwing directions;
- a speed of one or more inclusions departing from the snow throwing mechanism;
- a control module configured to control the rotary speed of the working motor to limit the speed of the one or more inclusions departing from the snow throwing mechanism to be equal to or less than 41 m/s;
- and
- a plurality of obstacle sensors respectively corresponding to the plurality of snow throwing directions, wherein the plurality of obstacle sensors send one or more signals when detecting an obstacle in the plurality of snow throwing directions;
- a signal receiving module configured to receive the one or more signals from the plurality of obstacle sensors;
- a signal processing module connected to the signal receiving module and configured to determine whether there is the obstacle in the plurality of snow throwing directions according to the one or more signals from the plurality of obstacle sensors;
- a signal output module connected to the signal processing module and configured to steer the snow throwing mechanism from a first snow throwing direction of the plurality of snow throwing directions to a second snow throwing direction of the plurality of snow throwing directions, different from the first snow throwing direction, when the signal processing module determines there is the obstacle in the first snow throwing direction and not in the second snow throwing direction, and wherein the second snow throwing direction is an area unprocessed by the automatic moving snow removal device.
An automatic moving snow removal device, comprising:
- a moving module driving the automatic moving snow removal device to move;
- a working motor having a rotary speed;
- a snow throwing mechanism driven by the working motor to collect and throw accumulated snow and inclusions on the ground out of the snow throwing mechanism in a plurality of snow throwing directions;
- an impulse of one or more inclusions departing from the snow throwing mechanism;
- a control module configured to control the rotary speed of the working motor to limit the impulse of the one or more inclusions departing from the snow throwing mechanism to be equal to or less than 0.041 Kg·m;
- and
- one or more obstacle sensors respectively corresponding to the plurality of snow throwing directions, and wherein the snow throwing mechanism is positionable to at least one snow throwing direction of the plurality of snow throwing directions that does not include an obstacle detected by the one or more obstacle sensors and is unprocessed by the automatic moving snow removal device.
