This utility model relates to the field of coal washing and screening, and more particularly to an adjustable vibration frequency coal washing and screening machine. It includes a base, guide rods, a vibrating frame, a first telescopic spring, a vibrating motor, and a screen. Two guide rods are connected to the left and right sides of the base, and the vibrating frame is slidably connected between the guide rods. A first telescopic spring connects each guide rod to the vibrating frame. A vibrating motor is connected to the front of the vibrating frame, and the screen is slidably engaged with the upper and lower parts of the vibrating frame. This utility model installs the screen by engaging it with the vibrating frame and then fixing it with a limiting frame. The vibration frequency of the vibrating motor is then adjusted, and coal is poured onto the screen for washing and screening. This allows for simultaneous installation and fixing of the screen while adjusting the vibration frequency to wash and screen coal of different particle sizes and densities. It facilitates screen replacement, reduces maintenance costs, improves coal processing efficiency, and is easy to use.

A small, adjustable fertilizer spreader for dryland planting, this utility model relates to the field of agricultural fertilization machinery technology; a rotating frame is screwed onto and fixed to the bottom of a discharge frame via bearings, and a conical guide frame is provided at the inner end of the rotating frame, with a discharge hole at the bottom of the rotating frame; a rotating gear is sleeved and fixed to the upper end of the rotating frame; a spreading motor is fixed to the frame via a motor bracket, and the spreading motor is located on the right side of the discharge frame, with the output shaft of the spreading motor passing through the frame and a transmission gear sleeved and fixed thereon, the transmission gear meshing with the rotating gear; a control platform is movably inserted through the bottom of the discharge frame, and the outer ring wall of the control platform is arranged in a conical inclination from top to bottom and from the inside to the outside; a control component is located inside the discharge frame; the purpose of spreading is achieved by driving the fertilizer to rotate horizontally, so that the fertilizer covers the soil surface, and the amount of fertilizer can be adjusted according to the soil needs.

The application discloses a kind of integrated polishing equipment for automobile sheet metal parts, it is related to automobile parts processing field, including polishing box, the inside of polishing box is equipped with rotating polishing head, polishing head is connected in the free end of mechanical cantilever, the free end of mechanical cantilever is equipped with dust collection head in the position close to polishing head, dust collection head is fixedly connected with one end of dust collection pipe, the other end of dust collection pipe is communicated with one end of dust collection box.The wet sponge disc in the application can adsorb these small particles, thereby making the air discharged from the wet sponge disc cleaner and less polluting to the environment.

The utility model discloses extruded sheet cooling forming equipment which comprises a cooling box and supporting legs. By adopting the movable frame, the cooling plates and the air outlet strips, after the extruded sheet is placed, the cooling plates can be driven to move back and forth along the surface of the extruded sheet through the movement of the movable frame, so that the cooling area of the extruded sheet is enlarged; the upper surface and the lower surface of an extruded sheet can be synchronously cooled at the same time, the situation that the product quality is affected by uneven temperature change caused by single-side cooling is avoided, cooling air can be continuously guided in through air outlet strips while cooling nozzles on the surface of the cooling plate conduct water cooling, and the cooling efficiency is improved. Heat on the surface of an extruded sheet is taken away through flowing of air, meanwhile, water vapor in the box body is discharged, the situation that heat discharge is affected by water vapor accumulation is avoided, the cooling structure can be enriched and the cooling effect can be improved through cooperative use of multiple sets of forms, and the beneficial effects of being good in cooling effect, sufficient in cooling and capable of achieving multi-form cooling are achieved.

The application discloses a drought-resistant and flood-draining pump with a buffer base, relates to the technical field of water conservancy projects, and is used for solving the problems that the existing pump body is easily blocked by floating objects during work, is damaged, and is easily deviated due to vibration generated during the work of the pump body, and comprises a pump body, a chassis and a handrail, the pump body is installed at the top of the chassis, the top of the chassis is fixed with the handrail through spot welding, the bottom of the chassis is installed with a supporting assembly, one side of the pump body is installed with a cleaning assembly, the sleeve is communicated with the pump body through bolts, the inside of the sleeve is fixedly connected with a fixing frame, and the fixing frame is movably connected with a first rotating blade on one side through a bearing. Compared with the prior art, the application has the advantages that the pump body can be better damped, floating objects in flowing water can be effectively collected, and the floating objects are prevented from entering the inside of the pump body to affect the work of the pump body.

This utility model discloses a portable environmental multi-parameter detection device, belonging to the field of air detection technology. It includes a housing, an air detector housed within the housing, a pump installed within the housing, an air duct mounted on the housing, and multiple filter plates housed within the housing. It also includes: a rotating cavity within the housing for the movement of the multiple filter plates; a mounting frame rotatably disposed within the housing for the installation and rotation of the multiple filter plates, with the multiple filter plates movably mounted on the mounting frame at equal angles in a ring shape; and an airflow cavity within the housing for guiding and discharging the gas detected by the air detector, which cleans the filter plates during discharge, making the device more convenient and efficient for detection.

The utility model discloses a kind of plastic pipe extrusion devices using PVC waste, belong to plastic extrusion production technical field, including bed, the bed top surface is equipped with machine cylinder, the machine cylinder top surface is equipped with feed hopper, the machine cylinder inside is equipped with screw rod;In the utility model, by setting exhaust component, through the design, it is realized in the process when extruding production, can be through first vent hole, second vent hole and exhaust seat exhaust to machine cylinder inside, and second vent hole can be opened to assist exhaust when first vent hole produces blockage, to reduce the influence caused by vent hole blockage Ensure that gas can be smoothly discharged, simultaneously, if first vent hole and second vent hole all produce blockage, then the position of exhaust seat can be changed first vent hole and second vent hole corresponding to it, and then corresponding adjustment is provided time for staff, to reduce the influence caused by vent hole blockage, guarantee the smooth progress of extrusion production.
