The utility model belongs to the technical field of drilling equipment. In view of the problems of dust drifting and inconvenience in cleaning of an existing road and bridge exploration drilling device, the utility model discloses a road and bridge exploration drilling device which comprises a device body, and the device body is characterized in that a shell is arranged at the top of a base; the supporting plate is arranged in the shell; the first motor is arranged at the top of the supporting plate; the drill rod is arranged at the output end of the first motor and penetrates through the supporting plate. A dust removal assembly is arranged on the base, and the dust removal assembly comprises a box body arranged on one side of the base; the dust collection fan is arranged at the top of the box body; the conveying pipe is arranged at the bottom of the dust collection fan and penetrates through the top of the box body; the dust suction port penetrates through the side wall of the base; and the air inlet pipe is arranged between the dust collection fan and the dust collection port. And through the dust removal assembly, it is avoided that powder and dust generated in the drilling process of the drill rod drift around, so that drilling work of workers is affected, the environment is polluted, and the collected dust is convenient to clean.

The utility model relates to the field of digital printing equipment, and discloses a feeding device for digital printing, which comprises a base, a printing machine is fixedly connected to the upper surface of the base, a roller is arranged on the right side of the upper surface of the base, a guide roller is arranged on the right side of the printing machine, and a U-shaped frame is fixedly connected to the center of the upper surface of the base. A limiting roller is rotationally connected to the center of the interior of the U-shaped frame, water absorption cloth is arranged above the limiting roller, a winding unit is arranged on the right side of the interior of the U-shaped frame, and a dehumidification unit is arranged below the limiting roller. According to the printing device, the U-shaped frame, the limiting roller, the water absorption cloth, the winding unit and the dehumidification unit are matched, so that water adhered to the outer side of the guide roller can be absorbed, and the situation that the printing effect is affected due to the fact that the humidity of the cloth is too high or the environment is polluted due to the fact that the water is adhered to the cloth passing subsequently is avoided.

This invention discloses a dust-proof and environmentally friendly construction waste recycling device in the field of construction waste recycling technology. It includes a magnetic mechanism and a crushing mechanism inside the outer shell. The crushing mechanism includes a cylindrical lifting block with multiple open cylindrical lifting block grooves at its bottom. The magnetic mechanism includes a cross-shaped magnetic suction frame. Both the lifting block grooves and the cross-shaped magnetic suction frame have independently controlled electromagnets built into them. This invention uses the magnetic suction mechanism and the crushing mechanism to lift and drop the cylindrical lifting block onto the concrete, effectively crushing it. Then, by raising the cross-shaped magnetic suction frame from the cylindrical lifting block and rotating it, the top layer of concrete is dispersed, and metal waste in the concrete is adsorbed layer by layer. This process is repeated until all the metal waste in the concrete is adsorbed, solving the problem of separating concrete and metal waste through crushing.

The utility model discloses a hardware calendering device relates to hardware calendering technical field, and the calendering device includes: base, is fixed with support on the base, is equipped with multiple groups of the compression roller for carrying out calendering to hardware products on the support through the elevating system, is equipped with the cleaning dust collection mechanism for cleaning the surface of compression roller and hardware products on the elevating system and the lateral side of support, and is equipped with the heating piece elevating system for carrying out heating to hardware products during calendering below the compression roller on the base, and the installation plate is installed through the elevating piece and can go up and down along the vertical direction, and multiple groups of the compression roller of fixed mounting are installed on the installation plate through the fixed frame and are arranged in parallel, and the cleaning dust collection mechanism is equipped on the limiting block. When using the device, the outer wall of the calendering roller is easy to contaminate the metal scrap in the process of carrying out the calendering operation to the steel plate in the prior art, which will affect the quality of the calendering of the steel plate and easily cause the problem of error.

The present invention discloses a cemented carbide reburning device and a cemented carbide reburning method. The cemented carbide reburning device comprises: a graphite box for containing the cemented carbide to be reburned; a filler layer, the filler layer is filled in the gap between the surrounding of the cemented carbide to be reburned and the graphite box shell; wherein the filler layer is formed by mixing Al2O3 powder and TiO2 powder, the mass fraction of the Al2O3 powder is 20-95%, and the remainder is TiO2 powder. It has been verified that the carburization degree of the cemented carbide treated by the cemented carbide reburning device and the cemented carbide reburning method of the present invention is significantly reduced, the magnetic saturation is significantly reduced, and the bending strength is significantly improved. It can be seen that the present invention has a simple structure, is easy to use, has a good decarburization effect, and has strong practicality.
