This invention relates to the field of blower noise reduction technology, and proposes a noise reduction device for a blower, including a pipeline with a cavity. The pipeline has an air inlet and several exhaust ports, and the cross-sectional area of ​​the exhaust ports is larger than that of the air inlet. The exhaust ports are used to connect to the blower's air outlet. This technical solution solves the problem in existing technologies where blower air outlets are simply protected, or even not protected at all, resulting in high noise levels inside the blower, affecting worker health, and reducing the blower's service life.

The present application relates to a kind of for sundry screen automatic cleaning roller robot system, comprising: robot body, the robot body includes: with the rigid connection of ground fixed base and six-axis mechanical arm;Wherein, six-axis mechanical arm, setting is on fixed base;The end of the six-axis mechanical arm carries cleaning roller device clamp.This application can reduce the exposure time of worker in harsh environment by introducing automation robot and supporting automation system to complete automatic cleaning roller operation, reduce the threat of dust inhalation, mechanical injury, heat radiation and the like to worker health.

This utility model provides a construction waste crusher, belonging to the field of waste treatment. It includes a shell, an adjustable crushing component, a dustproof component, and a compression component. In operation, the adjustable crushing component and dustproof component allow construction waste to be input via an external conveyor belt. A first motor drives a first crushing column to crush the waste. A limit block limits the movement of a nut. Rotating the nut moves a threaded column, a sliding column, a U-shaped plate, the first motor, and the first crushing column, allowing for adjustment of the crushing space according to the size and hardness of the materials to be crushed, preventing jamming. A sliding chamber facilitates the sliding of the first motor. A water tank stores water, which is pumped out by a water pump and sprayed out by a water sprayer to limit dust during the crushing process, achieving environmental protection and worker health protection.

This utility model discloses a feeding device for processing fireproof coatings, including a feeding bin. One side of the feeding bin has an installation port, and the other side has an inlet. A first clamping plate and a second clamping plate are symmetrically arranged on both sides inside the inlet. The first clamping plate is fixedly arranged in an inclined L-shape, and its top is equipped with a first clamping member. The second clamping plate is parallel to the first clamping plate and is movably disposed inside the inlet via a driving mechanism. A cutter perpendicular to the second clamping plate is arranged on one side via a rotating mechanism, and the cutter is located between the first and second clamping plates. This allows for flexible adjustment of the inlet opening size, enabling material bags to be fed into the feeding bin while the inlet is blocked, effectively preventing dust spillage and its adverse effects on the external environment and worker health.

This invention relates to the field of dust collection equipment technology and includes a support frame. The support frame comprises a left column and a right column positioned along the X-axis on either side of the welding station. A translation mechanism is installed between the left and right columns, positioned along the Y-axis. A fume hood is mounted on the translation mechanism. The fume hood includes a top and a curtain surrounding the edge of the top, together forming a dust collection area with an opening at the bottom. A drive motor is mounted on the left column, and the output shaft of the drive motor is connected to the top of the hood via a transmission assembly. One end of a telescopic smoke pipe is fixedly connected to the top of the hood and communicates with the dust collection area, while the other end of the telescopic smoke pipe is connected to a fume purifier. This invention can effectively collect fumes and harmful gases generated during welding within a limited space, improving the working environment and protecting worker health.
