The utility model discloses an anti-scattering guide chute with a coal recovery function, which relates to the technical field of coal processing and comprises a mounting rack, a shielding frame is fixed at the bottom of the mounting rack, an anti-falling collecting mechanism is arranged on one side of the shielding frame, and a mounting mechanism is arranged on the outer side of the anti-falling collecting mechanism. The anti-falling collecting mechanism comprises a material guide frame fixed to the edge of the bottom of the shielding frame, and a falling-back pipe is fixed to the bottom of the material guide frame. According to the anti-scattering material guide groove with the coal recycling function, the abutting block is attached to the surface of the conveying belt, when the sampling head rotates for sampling, the abutting block is used for shielding, the scattering amount of coal is reduced, and when the conveying belt deforms, a small part of coal is squeezed and discharged into the material guide frame from the bottom of the abutting block and falls into a recycling box through a falling-back pipe; and therefore, the coal is fully prevented from being scattered to the ground, the clean environment is guaranteed, the coal falling from the conveying belt can be conveniently recycled, and the practicability of the device is improved.

The application provides a supporting structure for landslide emergency treatment and a use method, and belongs to the technical field of landslide emergency treatment. The supporting structure comprises an anchor rod, a connecting mechanism is arranged on the anchor rod, the connecting mechanism comprises hollowed-out discs one, two and three which are fixedly sleeved on the anchor rod, the diameters of the hollowed-out discs one, two and three are sequentially reduced, a plurality of connecting rings are fixedly sleeved on the anchor rod, and grooves are arranged on the anchor rod corresponding to the connecting rings. The hollowed-out discs one, two and three and the connecting rings are fixedly sleeved on the anchor rod, the contact area of the anchor rod and the grouting body is increased through the hollowed-out discs one, two and three and the connecting rings, the connecting strength of the anchor rod and the grouting body is improved, the pull-out resistance of the anchor rod is increased, and therefore the support of the side slope is more stable and reliable.

The utility model belongs to the technical field of lifting and locking, particularly relates to a lifting and locking device, and aims to solve the problems that the packaging quality and efficiency are influenced due to position deviation of an existing charging basket in the lifting and packaging processes, the stability of the lifted charging basket is difficult to guarantee, and the packaging requirements of charging baskets with different heights cannot be flexibly met. Two third connecting bases are fixed to the top of the bottom plate, second connecting bases are arranged on the outer sides of the third connecting bases, and first connecting bases are welded to the tops of the second connecting bases. According to the barrel bottom positioning device, the accurate conical positioning table and a barrel bottom groove are matched for positioning, and an anti-inclination backing ring is matched, so that the positioning accuracy is guaranteed; the lifting process is ensured to be stable through stable oil cylinder pushing and guide rod guiding structures, the tray is effectively prevented from falling back through a reliable mechanical self-locking piece, the packaging height is ensured to be stable, and the tray lifting device is suitable for packaging charging baskets with different heights through the design of an adjustable adjusting pad and is high in universality.

This invention provides a ship steel plate sorting and grinding machine with force control compensation function, including a carrier plate; a sorting and gripping robot is installed on the top of the carrier plate, a conveying unit is provided on one side of the sorting and gripping robot, and a turning platform is provided on the other side of the sorting and gripping robot; a grinding robot is provided on one side of the turning platform; the turning platform includes a magnetic suction block; a force-controlled flexible grinding head is installed at the end of the grinding robot; a frame is provided at the bottom of the turning platform, and a cleaning brush is provided inside the frame. The cleaning brush is connected to a translation mechanism; the cleaning brush includes a brush plate and bristles fixed on the brush plate, and the brush plate has a plurality of air blowing holes evenly distributed; an air injection mechanism is installed on the cleaning brush. After the workpiece is ground, it can remove metal debris and dust attached to the ground surface of the ship steel plate. At the same time, the air injection mechanism can inject clean airflow into the gaps between the bristles through the air blowing holes on the cleaning brush, blowing away the debris and foreign objects embedded in the bristles, thereby achieving self-cleaning of the cleaning brush.

The present application relates to a kind of micro-hole machining center with good dust absorption effect, including base, be equipped with driving mechanism a on base and under the driving of driving mechanism a sliding table, base tail end is equipped with stand, be equipped with driving mechanism b on stand and under the driving of driving mechanism b sliding plate, sliding table is equipped with workbench, sliding plate is equipped with machining mechanism, machining mechanism includes drilling assembly and dust absorption component, the bottom of drilling assembly is equipped with pusher assembly, when drilling assembly is carried out drilling to workpiece placed on workbench, dust absorption component is cleaned to the chip generated, the up-down rotation of flap in dust absorption component is realized by pusher assembly, avoid chip back to fall into micro-hole, folding cover in pusher assembly continuously keep the sealing effect of micro-hole, the sealing effect of existing technology is not good enough, the problem that the dust absorption effect of the deeper micro-hole is not good enough is solved, residual is likely to cause, affect workpiece processing quality, still exist the problem of micro-hole blockage.

An excitation fuse structure includes an outer shell, an inner shell with an open end and a hollow interior, and a gas passage communicating with the open end of the inner shell between the outer shell and the inner shell. A piston is disposed in the open end of the inner shell, and an arc-extinguishing structure is disposed in the opposite end of the inner shell. The piston is in sealed contact with the inner wall of the inner shell. A conductive bar passes through the outer shell and the inner shell in a manner located along the piston's displacement path. An ignition device is disposed in the outer shell portion away from the open end of the inner shell, and one end of the ignition device's gas release is connected to the gas passage. The high-pressure gas released by the ignition device drives the piston through the gas passage to move from the open end of the inner shell towards the conductive bar located in the inner shell, thus disconnecting the conductive bar. By modifying the shell structure and lengthening the gas passage, the impact of high-pressure gas on the shell is reduced, thereby lowering the material and structural requirements for the shell.
