The invention discloses a sanding device. The sanding device comprises a sand storage device and a control mechanism. The control mechanism comprises a valve element on a valve. The valve element is rotationally arranged in the valve and provided with a first air hole, a second air hole and a third air hole. The positions, corresponding to the first air hole, the second air hole and the third air hole of the valve element, of the valve are provided with a first through hole, a second through hole and a third through hole. The first through hole is connected with the sand storage device. The second through hole is connected with an air pump. The third through hole is used for being connected with an air pipe of a machined workpiece. Connection and disconnection between the first air hole and the first through hole, between the second air hole and the second through hole and between the third air hole and the third through hole are controlled through rotation of the valve element. The sanding device is mainly designed for the problem of removing of rust on the inner wall of a pipe piece, fine sand is driven by airflow to enter from one end of the pipe piece, and when the fine sand passes through the inner diameter part of the pipe piece, the fine sand irregularly impacts on the inner wall of the pipe piece, and therefore the effect of rust removing is achieved.

An industrial derusting device comprises a moving part, a mechanical part, a chemical part and an air blowing and fire spraying part, wherein the lower end surface of a chute plate of the mechanical part is fixedly connected with the upper end surface of a long plate of the moving part; an acidic solution tank of the chemical part is fixedly arranged on the upper end surface of the long plate of the moving part; and a motor B of the air blowing and fire spraying part is fixedly arranged on the upper end surface of the long plate of the moving part. Working position of an electric turntable isadjusted by coordinating work between a steering engine A, a telescopic mechanism B, a steering engine B and a connecting arm A. One of a grinding wheel, a pneumatic needle bundle device and a steel wire brush is selected to carry out work through rotation of the electric turntable. The grinding and derusting of the wheel grind are achieved through a built-in power system; the pneumatic needle bundle device is provided with an air pump and a pneumatic needle, and knocking rust removal is achieved through coordinated work of the air pump and the pneumatic needle; and the steel wire brush utilizes the rotation of the specially-made round steel wire brush to remove iron rust by impact and friction.

The invention relates to a direct-mixing type multi-purpose automatic accurate fertilizer irrigation system which comprises a clean water tank, a raw fertilizer tank, a venturi tube, a fast fertilizer suction electromagnetic valve, an irrigation pump, an automatic control system, an electro connecting pressure gauge and a spherical fertilizer mixer, wherein the venturi tube sucks a raw fertilizer or an acid solution into a pipeline; the fast fertilizer suction electromagnetic valve controls a fertilizer suction amount; the output end of the irrigation pump is connected with the input end of the spherical fertilizer mixer through the pipeline, the pipeline positioned between the irrigation pump and the spherical fertilizer mixer is provided with the electro connecting pressure gauge; the output end of the spherical fertilizer mixer is respectively connected with an irrigation delivery pipeline and a fertilizer suction feedback pipeline; and the irrigation delivery pipeline is provided with an irrigation electromagnetic valve and a pipeline pressure detection device. The direct-mixing type multi-purpose automatic accurate fertilizer irrigation system disclosed by the invention realizes the immediate usage of a water fertilizer after mixing by adopting the independently developed spherical fertilizer mixer, can be used for furthest shortening the mixing time of a fertilizer and water and reducing the oxidation reaction generated because the fertilize contacts with air and can prevent the fertilizer waste generated in a fertilizer mixing process, provide higher output pressure through a direct-mixing type and cover more irrigated area.

The invention provides a friction type wire rod rust removal tool which comprises a main shaft, a plurality of long brushes, an opening groove shaft, a transmission mechanism and a brush inner pressing mechanism. The long brushes are located in the opening of the opening groove shaft, and the main shaft rotates and drives the brush inner pressing mechanism through the transmission mechanism to press the long brushes inwards, so that brush bristles rub a wire rod for rust removal. The tool has the advantages that the steel wire brushes can press the surface of the wire rod at constant pressure while revolving around the axis of a main shaft combined body to form a stable friction state and achieve the aim of rust removal; the tool is stable in operation, high in work efficiency, simple to operate, wide in application range, and capable of totally taking the place of acid pickling to serve as rust removal equipment free of acid pickling in the wire welding industry.

The invention relates to the technical field of iron wire derusting, and discloses a hand-held iron wire derusting device, which includes a handle, the top of the handle is fixed with a horizontal fixing cylinder connected by bolts, and the right end surface of the horizontal fixing cylinder is fixed by bolts A low-speed motor is connected, and the output shaft of the low-speed motor runs through the right side of the horizontal fixed cylinder and is fixedly connected with a torque shaft through a coupling. , the middle position of the top of the horizontal fixed cylinder is fixedly connected with an intermediate fixed bearing by bolts, the inner side of the intermediate fixed bearing is fixedly interspersed with a transverse transmission tube, the torque shaft is fixedly interspersed with two driving wheels, and the transverse transmission tube is fixedly interspersed with two The driven wheel corresponding to the driving wheel. The hand-held iron wire derusting equipment has changed the traditional way of manually derusting the iron wire, and reduced the labor intensity of the iron wire derusting operation.
