A vibration device for preventing blockage in a mining raw material chute includes a hopper. The hopper is characterized by a detachable mounting plate with two symmetrically welded grooves at intervals. Multiple sets of limiting holes are spaced apart on the grooves. A slider is positioned between the two grooves, and a vibrator is detachably mounted on the slider. Ear plates are provided on both sides of the slider, and the ear plates are adjustable and fixed via first bolts and limiting holes. This invention combines detachability and adjustability. The vibrator position can be precisely adapted to the material blockage situation. The bolted connection and convex groove structure ensure no loosening during vibration, effectively improving hopper unblocking efficiency and reducing maintenance costs.

The utility model discloses an adjustable safety guard rail belongs to safety guard equipment technical field, including telescopic vertical pole group, the number setting of telescopic vertical pole group is multiple groups, and multiple telescopic vertical pole group sets up vertically, telescopic cross bar group is located between two adjacent telescopic vertical pole group, and telescopic cross bar group with telescopic vertical pole group is perpendicular to set up, be equipped with connecting piece between telescopic cross bar group with telescopic vertical pole group to make telescopic cross bar group with telescopic vertical pole group between rotatable adjustable, fixed assembly is located at the bottom of telescopic vertical pole group and is used for with ground fixed connection. The utility model discloses an adjustable safety guard rail can effectively solve the problem that the existing safety guard rail is difficult to adapt to different size shape of the hole, and the installation and removal are complicated, and the safety performance is insufficient.

The utility model relates to the technical field of automobile parts production and assembly, and particularly discloses an automobile front bumper camera assembly structure, which comprises a skin (1), an outer plate (2), a support (3), an inner plate (4) and a headlamp assembly, and the inner plate (4) is fixedly connected with the skin (1), the outer plate (2) and the support (3) to form a channel (8). The automobile front bumper camera assembly structure is novel in design, scientific in design, reasonable in structure, reliable and safe in action, durable, easy to maintain in the future, and accurate in auxiliary positioning during assembly.

The present application belongs to the technical field of crane, and provides a large pin gear follow-up transmission mechanism of a diagonal bracing type mast crane, comprising a chassis, a pin gear slewing ring arranged on the top of the chassis, and a slewing structure arranged on the top of the pin gear slewing ring, wherein the pin gear slewing ring is improved by the reduction device of the diagonal bracing type mast crane, the transmission gear is made to slide up and down on the surface of the reduction machine output shaft by adding a follow-up device, and the transmission gear is made to move in cooperation with the deformation of the pin gear slewing ring by the action of the follow-up spring, so that when the pin gear slewing ring rotates and appears to be disturbed downward or upturned, the follow-up spring will make the transmission gear move adaptively to maintain a normal working state, effectively solving the problems of wear and interference between the transmission gear and the pin gear, thereby prolonging the service life of the whole transmission device, and the device is simple and practical in structure and convenient to disassemble and maintain, thereby greatly reducing the enterprise operation and maintenance cost and improving the equipment operation and maintenance efficiency.
