The invention relates to a device for combing and conditioning artificial turf, which comprises a handle (1), a pole (2), a head (3) which houses an electric motor (4), and a pair of brushes (5) driven by the electric motor (4), the brushes (5) being configured for combing and conditioning the artificial turf, and such that the brushes (5) have a helical shape. The device comprises a transmission that comprises a motor output shaft (9) that is associated with a transmission belt (10), which transmits the rotation to a toothed wheel (11), the wheel (11) transmits the rotation to a transmission shaft (12) which ends in a worm screw (13) that transmits the rotation to a transverse shaft (14) via a toothed wheel (15) attached to the transverse shaft (14) that houses the pair of brushes (5).

A backpack tool, a backpack blower and a control handle assembly are provided by the present invention. The backpack tool includes a battery pack for providing electrical energy, a power assembly electrically connected with the battery pack to convert the electrical energy provided by the battery pack into mechanical energy, and a backpack assembly carried on the human back to support the battery pack and the power assembly. Both the battery pack and the power assembly can be carried on the human back using the backpack assembly, so that the weight carried by the arms of the worker can be reduced. The battery pack serves as a power source that reduces the noise and vibration caused by the backpack tool during operation as compared with a gasoline powered backpack tool.

A backpack tool system and a backpack power supply apparatus for use with an electric tool. The backpack power supply apparatus includes a battery pack for providing electric energy, a body for carrying the battery pack, and a wearable device connected to the body and wearable by a user to carry the body. The battery pack is detachably connected to the body. The body defines a plane and a height extending in a heightwise direction. The body is at least partially symmetrical about the plane. The wearable device includes a strap, which includes an upper end connected to an upper portion of the body. The upper end of the strap applies a force to the body when the user wears the wearable device. An included angle between a projection of a direction of the force on the plane and the heightwise direction is greater than or equal to 30 degrees and less than or equal to 50 degrees.

A rolling assembly, the rolling assembly including: a body; one or more surface rollers rotatable with respect to the body; and at least one rotatable sweeping device including: an elongate member rotatable with respect to the body; and a sweeping head located over the elongate member and rotatable with respect to the elongate member, wherein the sweeping head is configured to engage with the one or more surface rollers such that the rotation of the one or more surface rollers rotates the sweeping head.

The invention provides for a method of maintaining artificial turf using a turf maintenance robot. The artificial turf comprises an artificial turf carpet, wherein the artificial turf carpet comprises turf fibers which form an artificial turf surface. The artificial turf fibers have a grain. The artificial turf comprises artificial turf infill distributed between the artificial turf fibers. The turf maintenance robot is a self driving robot, wherein the turf maintenance robot comprises a memory for storing turf grain data, descriptive the grain of the artificial turf fibers. The method comprises brushing the artificial turf surface by the turf maintenance robot. The turf maintenance robot performs the brushing dependent upon the turf grain data.

The present invention relates to a blowing-suction device, selectively operating in a blowing mode or a suction mode, comprising: a main body; a motor located inside the main body, the motor having a motor shaft providing rotational motion; a fan assembly driven by the motor to rotate; and a blowing assembly and a suction assembly connected to the main body; wherein the fan assembly includes an axial fan that, while in the blowing mode, the blowing assembly is connected to the main body, and wherein the axial fan rotates around a first rotary shaft, and, while in the suction mode, the suction assembly is connected to the main body.

The present invention relates to a self-moving device (100). The self-moving device (100) includes a body (20), a walking mechanism (40) disposed on the body (20) and configured to drive the self-moving device (100) to walk, a connecting arm (60) connected to the body (20), and a control module (11) configured to control the walking mechanism (40) to drive the self-moving device (100) to walk within a defined area. The connecting arm (60) is selectively connected to at least one of at least two working heads (200) configured to perform different work tasks. The connecting arm (60) includes a connecting structure (64) configured to be connected to the working head (200) and a connecting component (62) configured to connect the connecting structure (64) to the body (20).

The present disclosure relates to a self-moving device. The self-moving device includes a movement mechanism disposed on a body of the self-moving device and configured to drive the self-moving device to move; a connecting arm connected to the body and at least one working head of a plurality of working heads configured to perform different work tasks; a safety detection module configured to detect whether at least one of the self-moving device or the at least one working head is in a safe working environment; and a controller configured to control a working status of at least one of the self-moving device or the at least one working head based at least in part on a detection result of the safety detection module.
