  • Publication number: 20240074350
    Abstract: A mower system comprising a powered mower, a connecting device connected to the powered mower and an attachment connected to the powered mower through the connecting device for conducting specified function during the operation of the mower system. The connecting device includes a mounting assembly mounted to the powered mower and a base rotatably mounted to the mounting assembly for driving the attachment being rotated together with the base in a horizontal plane relative to the powered mower. The utilization rate of the powered mower is effectively improved because other working functions can be conducted by the attachment which is connected to the powered mower through the connecting device.

  • Publication number: 20230152354
    Abstract: Adsorbable electromagnetic field auxiliary device for large components, comprises an iron core being adsorbed on the component to be processed with an integral rectangular frame including a pair of lateral sides and a pair of longitudinal sides; lateral sides are installed with electromagnetic coils having opposite magnetic pole pointing to the component. A photoelectric sensor installed on the longitudinal side senses the real-time position of the laser head; the longitudinal opposite sides are each provided with a screw movement device and a brush device; the brush head of the brush device slides on the surface of the component forming a directional electric field; the motor controlled by the central controller adjusts the position of the brush device, so that the two brush heads and the laser head are always in a straight line to ensure the stability of the electric field in the laser processing area and uniformity.

  • Patent number: 9945034
    Abstract: A metal-based/diamond laser composite coating preparation method includes: first selecting high-hardness metal powder and diamond powder of a proper grain size and shape; then uniformly mixing the high-hardness metal powder and diamond powder via a ball-milling method; and finally preparing a composite coating on a substrate by synchronously combining laser texturing technology, laser thermal treatment technology and cold spraying technology. The thickness of the composite coating is greater than 1 mm, and the volume content of diamond in the coating is greater than 45%. A metal-based/diamond laser composite coating is also provided.
