And the sizes of the two driving wheels 1 and the steering wheel mechanism 30 are adjusted to be the same, three wheels are distributed in the same plane at 120 degrees, and the three wheels can be independently driven by adopting Swedish wheels. Then in this embodiment the device may implement omni-directional mobility capabilities.
In another embodiment of the invention, in order to improve the energy-saving effect of the invention, the weeding machine further comprises a storage battery 8, and the storage battery 8 is respectively connected with the main motor 7, the rotary weeding assembly, the rotary motor assembly and the steering motor assembly. The weeder still includes solar panel, and solar panel locates on the top cap, and solar panel is connected with battery 8. Although the whole weight of the equipment is slightly increased by the design, the places such as orchards and lawns used by the equipment are generally full of sunlight, so that better energy-saving and emission-reducing effects can be achieved on the whole.
When the weeding machine is used, when the equipment only needs to clean weeds on the surface, the front cutter head 29 of the rotary weeding assembly is driven to be in a horizontal position by the rotary motor assembly, and the weeds are removed. The fixed weeding assembly and the rotary weeding assembly operate simultaneously to ensure that weeds are removed cleanly.
When the equipment needs to cut off the grass roots of weeds while weeding, the rotating motor 23 which rotates the motor assembly runs to drive the disc rotating wheel 24 to rotate, the cam rotating disc 26 is driven to rotate by a certain angle through the transmission of the middle connecting rod 25, and the circle center of the cam rotating disc 26 is rigidly connected with the rotating weeding assembly, so that the rotating weeding assembly can rotate by a certain angle, the whole front cutter head 29 is in a state of being high in the front and low in the rear, and the weeds at the front end are gradually cut off from high to low along with the advancing of the weeding machine. Meanwhile, the tool tip at the rearmost part can turn over soil, and the working target of cutting off grass roots is achieved.
The above embodiments are merely examples and do not limit the scope of the present invention. These embodiments may be implemented in other various manners, and various omissions, substitutions, and changes may be made without departing from the technical spirit of the present invention.
