A vehicular sweeping machine includes a frame and a broom assembly that is mounted to the frame. The broom assembly includes a broom enclosure, a left hub that is mounted on a left hub mount arm, and a right hub that is mounted on a right hub mount arm. A broom is mounted between the left hub and the right hub. An outer tube is attached to the rear of the broom enclosure and to one of the left and right hub mount arms. An inner tube has a fixed end that is attached to the left or right hub mount arm to which the outer tube is not attached. The inner tube also has a free end that is adapted to slide within the outer tube. A linear actuator is attached between the broom enclosure and the left or right hub mount arm to which the fixed end of the inner tube is attached. The linear actuator is adapted to move the hub mount arm to which it is attached between an inner position in which the broom is engaged with the left hub and the right hub and an outer position in which the broom is disengaged from one or both of the left hub and the right hub.

A mobile vehicle, a ground treating equipment and an orientation adjusting method thereof are provided. The ground treating equipment includes a frame, a ground treating unit, a connecting rod set, a connecting rod driving unit, a rotation driving unit, two pressure sensors and a controller. The ground treating unit is mounted at the frame. Two ends of the connecting rod set are connected to the frame and the mobile vehicle. The connecting rod driving unit is mounted at the connecting rod set for adjusting the orientation of the connecting rod set. The rotation driving unit is mounted between the frame and the connecting rod set for driving the frame to rotate relative to the connecting rod set. The pressure sensors are mounted at the frame for sensing two pressure values between the frame and ground, or the pressure sensors are mounted at the rotation driving unit for sensing two pressure values while the frame is driven to rotate clockwise and counter-clockwise. The controller is configured to control the connecting rod driving unit and the rotation driving unit for changing the two pressure values.

A road sweeper machine (1) is provided comprising a vehicle (2) suitable for road transport e comprising an electric motor (3), sweeping elements (4) connected to the vehicle (2) and suitable to remove waste on the ground, a waste collection system (5) placed at the bottom of the vehicle (2), a chamber (6) for containing the collected waste connected to the collection system (5), the electric motor (3) is of brushless type and comprises a hexa-phase system (30), the hexa-phase system (30) comprising a rotor (31) comprising a plurality of magnets of permanent type, two stators (32), two inverter circuits (33), each one connected to one of the stators (32), and each one mutually independent, each inverter (33) being capable of sending a three-phase current to the connected stator (32).

A mobile collection device including a vehicle assisted working device for cleaning surfaces, and an autonomously self-driving robot vehicle. The working device includes a brush for detachment of extraneous material from the surface, a blower configured to provide an underpressure for a suction of the detached material into the air flow from the surface, and a cyclone configured to separate material from the air flow. The blower is configured to provide an overpressure and return of the separated air to the surface. The brush is configured to rotate counter-wise to a forward movement direction of the working device. The working device is configured such that the spot is treated in the following order: the blower provides the underpressure for the suction of the detached materials, the counter-rotating brush brushes the spot, and the blower provides the overpressure and return of the separated air to the surface via an air-knife.

The application provides a multifunctional robotic device including a body, an energy unit installed in the body, a power unit powered by the energy unit, the power unit including an output shaft wherein the output shaft is located at the lower part of the body and exposed from the body, and at least two working units, the working unit is detachably connected to output shaft of the power unit and driven by the power unit.

In accordance with one aspect, a lawn sweeper for being towed by a lawn tractor including a body, a rotatable brush mounted to the body, and a motor for rotating the brush independently of the rotation of at least one wheel of the lawn sweeper. The lawn sweeper further includes a remote control for being operated by a user of the lawn tractor to control the motor. In another aspect, a lawn sweeper having a pair of wheels rotatable about a wheel axis, a body shiftable between raised and lowered positions relative to the wheels, and brush mounted to the body and rotatable about a brush axis.
