The right side of the electric push rod is slidably installed inside the electric slide rail. The right side of the dust suction assembly is fixedly installed on the left side of the telescopic end of the electric push rod. The telescopic end of the electric push rod drives the dust suction assembly to move left and right while moving up and down, so that the dust suction assembly can automatically grasp the absorption distance of the material dust. The right side of the convex ball rubber rod is fixedly installed on the left side of the dust suction assembly shaft, and the convex ball on the outer wall of the convex ball rubber rod is penetrated and slidably installed. The rotating shaft of the dust suction assembly drives the convex ball rubber rod to move synchronously while causing the convex ball rubber rod to rotate and rub the material, and the convex ball rubber rod is used to brush the solidified dust on the outer wall of the material.

[0007] The U-shaped telescopic clamp is fixedly mounted on the outer wall surface of the telescopic end of the electric push rod, and the telescopic end of the electric push rod drives the U-shaped telescopic clamp to move synchronously. When the U-shaped telescopic clamp contacts the material and generates a resistance force, the telescopic end itself extends to adapt to the material clamping size. The back side of the arc groove film is fixedly mounted on the back side of the inner wall of the telescopic end of the U-shaped telescopic clamp, and the telescopic end of the U-shaped telescopic clamp drives the arc groove film and the rotating wheel to move synchronously.

The left side of the electric telescopic column is fixedly installed on the left side of the inner wall of the dust clean room. When the electric telescopic column is started, the telescopic end of the electric telescopic column drives the resistance plate to move left and right. The left side of the resistance plate is fixedly installed on the right side of the telescopic end of the electric telescopic column. When the resistance plate moves toward the center of the dust clean room, the resistance spring plate is deformed.

[0010] According to the above technical solution, the anti-dispersion device includes a connecting rod, a cooling water ring and a scraper block. The left side of the connecting rod is slidably installed inside the arc groove of the electric rotating rod. When the electric rotating rod rotates, the arc groove restricts the connecting rod, so that the connecting rod can move forward and backward. The right side of the outer wall of the cooling water ring is slidably installed on the inner wall of the atomizer gun, and the right side of the inner wall of the cooling water ring is fixedly connected to the right side of the connecting rod. The connecting rod drives the cooling water ring to synchronously scrape the inner wall of the atomizer gun. The cooling water ring cools the water source to reduce water source loss. The back of the scraper block is slidably installed on the front of the cooling water ring through a spring. The cooling water ring drives the scraper block to move synchronously to remove scale and avoid scale accumulation.

[0011] According to the above technical solution, the anti-dispersion device further includes a telescopic rod, a reset piece, a hinge plate and a transmission ring. The bottom of the telescopic rod is fixedly installed at the top edge of the cooling water ring, and the top of the telescopic end of the telescopic rod is fixedly connected to the bottom of the filter plate.

When the reset piece deforms, it reduces the internal flow area of the atomizing gun through its own arc surface, increasing the internal pressure of the atomizing gun. The left side of the hinge plate is hinged to the right arc surface of the reset piece.

The bottom of the spring piece is fixedly installed at the top of the outer wall of the convex spherical rubber rod, and the spring piece is located on the moving track of the convex sphere. When the convex sphere in the convex spherical rubber rod touches the material, it slides along the outer wall of the rubber rod towards the dust collection component. The convex sphere touches the spring piece and deforms it. The top of the collecting net plate is fixedly installed at the bottom of the outer wall of the convex spherical rubber rod. The spring piece pushes the convex sphere to reset through elastic force. When the spring piece deforms and recovers, it drives the T-shaped pressing plate to roll and crush the larger dust blocked by the inner wall of the collecting net plate. The top of the T-shaped pressing plate penetrates and is fixedly installed at the concave surface of the inner wall of the spring piece, and the right side of the bottom of the T-shaped pressing plate contacts the right side of the inner wall of the collecting net plate.

The left side of the vertical plate is fixedly installed on the right side of the T-shaped pressing plate. The T-shaped pressing plate drives the vertical plate to move left and right. When the vertical plate drives the rolling wheel to slide along the inner wall of the collecting net plate, friction is generated. The back of the rolling wheel is rotatably installed on the front of the vertical plate, and the outer wall of the rolling wheel contacts the inner wall of the collecting net plate. The rolling wheel starts to rotate through friction to perform more delicate rolling on the solid block dust. The arc-shaped piece is fixedly installed between the right side of the collecting net plate and the left side of the inner wall of the T-shaped pressing plate. The T-shaped pressing plate touches the arc-shaped piece and deforms and recovers synchronously. When the arc-shaped piece recovers, it provides power for the reset of the T-shaped pressing plate. The front of the knocking column is fixedly installed on the back of the arc-shaped piece, and the inner wall of the collecting net plate is located on the moving track of the knocking column.

It has the following beneficial effects: (1) The present invention sets an anti-loosening device, and cooperates with an electric slide rail, an electric push rod, a dust suction component and a convex ball rubber rod, so that the electric push rod drives the dust suction component to move left and right and up and down at the same time, so that the dust suction component can automatically grasp the absorption distance of the material dust, thereby improving the dust suction efficiency and reducing the possibility of dust flying and overflowing; at the same time, the ball rubber rod rotates and rubs the material, which promotes the decomposition of mud and dust, improves the cleanliness of the material and improves the detection accuracy; through the cooperation of the U-shaped telescopic clamp, the arc groove film, the rotating wheel and the L-shaped vibration plate, the U-shaped telescopic clamp can adapt to the material clamping size to avoid the material shaking when the convex ball rubber rod is brushing, thereby reducing the mud and dust removal effect; at the same time, the arc groove film increases the clamping force of the U-shaped telescopic clamp on the material and improves the stability; the rotating wheel also increases the smoothness of the U-shaped telescopic clamp when clamping the material; at the same time, the L-shaped vibration plate promotes the vibration of the U-shaped telescopic clamp through the force transmission effect, weakens the adhesion strength of dirt on the outer wall of the material, and improves the brushing effect of the convex ball rubber rod.

[0015] (2) The present invention sets an anti-adhesion device, and cooperates with an electric telescopic column, a contact plate and a spring plate, so that the spring plate will swing back and forth during the resetting process to flap the splashed solid particles, thereby preventing the solid particles from attaching to the surface of the test material for the second time, increasing the staff's participation time, and avoiding the overall adverse effects on the material detection level; through the cooperation of the twisting plate, the dust-removing water bag, the atomizing gun and the electric rotating rod, the dust-removing water bag sprays the dust-reducing water source through the atomizing gun to wet the cement dust, increase the dead weight of the mud and dust, and avoid respiratory diseases caused by inhalation by the staff, thereby ensuring health; at the same time, the electric rotating rod promotes the outward expansion of the water flow, thereby expanding the dust-reducing range of the water flow, and at the same time shields the mud and dust through the arc surface, thereby reducing the adhesion area of ​​the mud and dust to the inner wall of the atomizing gun.

[0016] (3) The present invention sets an anti-dispersion device, and cooperates with an electric rotating rod, a connecting rod, a cooling water ring and a scraper block, so that the cooling water ring cools the water source, reduces the evaporation content of the water source, and improves the utilization efficiency of the water source; at the same time, the scraper block moves to remove scale, avoids scale accumulation, and improves the scraping force of foreign matter; through the cooperation of the telescopic rod, the reset plate, the hinge plate and the transmission ring, when the reset plate is deformed, the internal flow area of ​​the atomizing gun is reduced through its own arc surface, the pressure is increased, the water source is concentrated, and the water source is prevented from being dispersed and shortening the spraying distance; at the same time, the hinge plate further reduces the flow aperture on the original basis, so as to avoid the twisting plate from squeezing the dust-cleaning water bag insufficiently and reducing the spraying force; and the transmission ring also blocks the connection between the telescopic end of the telescopic rod to prevent solid dirt from getting stuck and making it difficult for the telescopic rod to freely extend and retract.

[0017] (4) Through the setting of the anti-blocking device, the convex spherical rubber rod, the elastic sheet, the collecting net plate and the T-shaped pressing plate cooperate to make the elastic sheet drive the T-shaped pressing plate to roll and crush the larger dust blocked by the inner wall of the collecting net plate, preventing the dust from directly entering the inside of the dust suction component and causing damage. At the same time, the collecting net plate separates the solid block dust and the dust, preventing them from mixing and entering the inside of the dust suction component. Through the cooperation of the vertical plate, the rolling wheel, the arc-shaped sheet and the knocking column, when the rolling wheel rotates, it can roll and crush the solid block dust more finely, improving the crushing effect of the T-shaped pressing plate and preventing the collecting net plate from being blocked. At the same time, when the arc-shaped sheet returns, it provides power for the reset of the T-shaped pressing plate, preventing the reset from getting stuck. It also makes the knocking column repeatedly knock on the inner wall of the collecting net plate to generate vibration, reducing the adhesion strength of the dust, and preventing the dust rolled by the T-shaped pressing plate from adhering to the surface of the inner wall of the collecting net plate.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

The anti-loosening device 4 includes an electric slide rail 41, an electric push rod 42, a dust suction component 43 and a convex ball rubber rod 44. The right side of the electric slide rail 41 is fixedly installed on the left side of the L-shaped plate 3. The right side of the electric push rod 42 is slidably installed inside the electric slide rail 41. The right side of the dust suction component 43 is fixedly installed on the left side of the telescopic end of the electric push rod 42. The right side of the convex ball rubber rod 44 is fixedly installed on the left side of the rotating shaft of the dust suction component 43, and the convex ball on the outer wall of the convex ball rubber rod 44 is penetrated and slidably installed. Place the material on the outer wall of the transmission component 2, and drive the transmission component 2 to operate through the external belt pulley to realize the automatic material conveying process. Start the electric slide rail 41 and the electric push rod 42. The electric slide rail 41 drives the electric push rod 42 to move up and down. The telescopic end of the electric push rod 42 drives the dust suction component 43 to move left and right and up and down at the same time, realizing the automatic control of the absorption distance of the dust suction component 43 for the material dust. The rotating shaft of the dust suction component 43 drives the convex ball rubber rod 44 to move synchronously and at the same time prompts the convex ball rubber rod 44 to rotate and rub the material, and brushes the firmly solidified dust on the outer wall of the material through the convex ball rubber rod 44.

The top of the electric rotating rod 57 is rotatably installed on the bottom of the filter plate in the atomizing gun 56, and the outer wall of the electric rotating rod 57 is provided with an arc groove. The bottom of the outer wall of the electric rotating rod 57 is an arc-shaped surface. When the spring plate 53 swings, it drives the torsion plate 54 to reciprocate and recover. The torsion plate 54 squeezes the dust-removing water bag 55 and contracts synchronously to generate a spray force. The dust-removing water bag 55 sprays the dust-reducing water source through the atomizing gun 56. The dust-reducing water source is used to wet the overflowing cement dust, increase the dead weight of the mud and dust, and prevent the staff from inhaling it into the body and causing respiratory diseases. The electric rotating rod 57 is started. When the electric rotating rod 57 rotates, the arc-shaped surface is used to promote the water flow to expand outward, thereby expanding the dust-reducing range of the water flow to a certain extent.

[0025] When in use, the material is placed on the outer wall of the transmission component 2, and the transmission component 2 is driven to operate through the external pulley to realize the automated material conveying process; the electric slide rail 41 and the electric push rod 42 are started, and the electric slide rail 41 drives the electric push rod 42 to move up and down, and the telescopic end of the electric push rod 42 drives the dust suction component 43 to move left and right while moving up and down, so that the dust suction component 43 automatically grasps the dust absorption distance of the material, improves the dust suction efficiency and reduces the possibility of dust flying and overflowing; the rotating shaft of the dust suction component 43 drives the convex ball rubber rod 44 to move synchronously, and at the same time, the convex ball rubber rod 44 causes the material to rotate and rub, and the convex ball rubber rod 44 is used to brush the solidified dust on the outer wall of the material, so as to decompose the mud and dust, improve the cleanliness of the material and improve the detection accuracy; the telescopic end of the electric push rod 42 drives the U-shaped telescopic clamp 45 to move synchronously, and the U-shaped telescopic clamp When 45 contacts with the material and generates a resistance force, its own telescopic end extends to adapt to the material clamping size, thereby avoiding the material from shaking when the convex ball rubber rod 44 brushes, and preventing the mud and dust removal effect of the material from being reduced; the telescopic end of the U-shaped telescopic clamp 45 drives the arc groove film 46 and the rotating wheel 47 to move synchronously, and the arc groove film 46 increases the clamping force of the U-shaped telescopic clamp 45 on the material through its own arc groove surface, further improving the stability; the arc surface of the rotating wheel 47 contacts with the material and generates friction, and the self-rotation of the rotating wheel 47 increases the smoothness of the U-shaped telescopic clamp 45 when clamping the material; when the rotating wheel 47 rotates, it contacts the L-shaped vibration plate 48 and is deformed. During the recovery process of the L-shaped vibration plate 48, it will swing back and forth to generate vibration, and the force transmission effect will cause the U-shaped telescopic clamp 45 to vibrate, weaken the adhesion strength of dirt on the outer wall of the material, and improve the brushing effect of the convex ball rubber rod 44.

[0026] When the convex spherical rubber rod 44 is brushed, the electric telescopic column 51 is started. The telescopic end of the electric telescopic column 51 drives the contact plate 52 to move left and right. When the contact plate 52 moves towards the center of the dust-free chamber 31, the elastic plate 53 deforms. When the contact plate 52 crosses the elastic plate 53, the contact force disappears and the elastic plate 53 automatically resets by its own elasticity. During the reset process of the elastic plate 53, it will swing back and forth to pat the splashed solid particles, preventing the solid particles from adhering to the surface of the detected material again, increasing the participation time of the staff, and at the same time avoiding adverse effects on the flatness of the material detection; when the elastic plate 53 swings, it drives the torsion piece 54 to deform and recover reciprocally. The torsion piece 54 squeezes the dust-removing water bag 55 to contract synchronously to generate a spraying force.

When the electric rotating rod 57 rotates, it promotes the outward expansion of the water flow through the arc surface, expanding the dust-removing range of the water flow to a certain extent, and at the same time blocking the mud dust through the arc surface to reduce the adhesion area of the mud dust to the inner wall of the atomizing gun 56.

The back of the scraping block 63 is slidably installed on the front of the cooling water ring 62 through a spring. When the electric rotating rod 57 rotates, due to the restriction of the arc-shaped groove on the connecting rod 61, the connecting rod 61 can move back and forth, and the connecting rod 61 drives the cooling water ring 62 to scrape the inner wall of the atomizing gun 56 synchronously. The cooling water ring 62 cools the water source for reducing water loss, and the cooling water ring 62 drives the scraping block 63 to move synchronously to remove scale, avoiding scale accumulation.

[0028] The anti-dispersion device 6 further includes a telescopic rod 64, a reset piece 65, a hinge plate 66 and a transmission ring 67. The bottom of the telescopic rod 64 is fixedly installed at the top edge of the cooling water ring 62, and the top of the telescopic end of the telescopic rod 64 is fixedly connected to the bottom of the filter plate. The left side of the reset piece 65 is fixedly installed between the right side of the telescopic rod 64 and the right side of the telescopic end of the telescopic rod 64. The left side of the hinge plate 66 is hinged to the right arc surface of the reset piece 65. The front surface of the inner wall of the transmission ring 67 is hinged to the front surface of the reset piece 65, and the middle ring of the transmission ring 67 is sleeved and slid on the outer wall surface of the telescopic end of the telescopic rod 64. The cooling water ring 62 drives the telescopic rod 64 to move synchronously. When the telescopic end of the telescopic rod 64 moves up and down, it drives the reset piece 65 to deform and recover. When the reset piece 65 deforms, it reduces the internal flow area of the atomizing gun 56 through its arc surface, increases the internal pressure of the atomizing gun 56. The arc surface of the reset piece 65 drives the hinge plate 66 to move and reset towards the center of the atomizing gun 56, further reducing the flow aperture on the original basis. The reset piece 65 drives the transmission ring 67 to move up and down, and the transmission ring 67 shields the connection part of the telescopic end of the telescopic rod 64.

[0029] The anti-blocking device 7 includes a spring piece 71, a collecting net plate 72 and a T-shaped pressing plate 73. The bottom of the spring piece 71 is fixedly installed at the top of the outer wall of the convex spherical rubber rod 44, and the spring piece 71 is located on the moving track of the convex sphere. The top of the collecting net plate 72 is fixedly installed at the bottom of the outer wall of the convex spherical rubber rod 44. The top of the T-shaped pressing plate 73 penetrates and is fixedly installed at the concave surface of the inner wall of the spring piece 71, and the right side of the bottom of the T-shaped pressing plate 73 is in contact with the right side of the inner wall of the collecting net plate 72. When the convex sphere in the convex spherical rubber rod 44 contacts the material, it slides along the outer wall of the rubber rod towards the dust suction component 43. The convex sphere contacts the spring piece 71 and deforms it. The spring piece 71 pushes the convex sphere to reset through its elastic force. When the spring piece 71 deforms and recovers, it drives the T-shaped pressing plate 73 to roll and crush the larger mud and dust blocked by the inner wall of the collecting net plate 72. At the same time, the collecting net plate 72 separates the solid block mud and dust from the dust, preventing them from mixing and entering the inside of the dust suction component 43.

[0030] The anti-blocking device 7 also includes a vertical plate 74, a rolling wheel 75, an arc-shaped piece 76 and a knocking column 77. The left side of the vertical plate 74 is fixedly installed on the right side of the T-shaped pressure plate 73, the back of the rolling wheel 75 is rotatably installed on the front of the vertical plate 74, and the outer wall of the rolling wheel 75 contacts the inner wall of the collecting mesh plate 72, the arc-shaped piece 76 is fixedly installed between the right side of the collecting mesh plate 72 and the left side of the inner wall of the T-shaped pressure plate 73, the front of the knocking column 77 is fixedly installed on the back of the arc-shaped piece 76, and the inner wall of the collecting mesh plate 72 is located at the movement of the knocking column 77. On the track, the T-shaped pressure plate 73 drives the vertical plate 74 to move left and right, and the vertical plate 74 drives the rolling wheel 75 to slide along the inner wall of the collecting mesh plate 72 to generate friction. The rolling wheel 75 starts to rotate through the friction force to grind the solid block dust more finely, and the T-shaped pressure plate 73 resists the arc piece 76 and deforms and recovers synchronously. When the arc piece 76 recovers, it provides power for the T-shaped pressure plate 73 to reset. When the arc piece 76 is deformed, it drives the knocking column 77 to knock back and forth on the inner wall of the collecting mesh plate 72 to generate vibration and reduce the adhesion strength of the dust.

[0031] When in use, when the electric rotating rod 57 rotates, the arc groove restricts the connecting rod 61, so that the connecting rod 61 can move forward and backward, and the connecting rod 61 drives the cooling water ring 62 to scrape the inner wall of the atomizing gun 56 synchronously. The cooling water ring 62 cools the water source, so that the water source is kept at a low temperature for spraying, the evaporation content of the external high-temperature water source is reduced, and the utilization efficiency of the water source is improved; at the same time, the cooling water ring 62 drives the scraping block 63 to move synchronously to remove scale and avoid scale accumulation; the scraping block 63 is set by the spring, and when it is subjected to the resistance force, it contracts and accumulates force, thereby improving the scraping force against foreign objects; the cooling water ring 62 drives the telescopic rod 64 to move synchronously, and when the telescopic end of the telescopic rod 64 moves up and down, it drives the reset plate 65 to recover its deformation. When the reset piece 65 is deformed, the internal flow area of ​​the atomizer gun 56 is reduced through its own arc surface, the internal pressure of the atomizer gun 56 is increased, the water source is sprayed in a concentrated manner, and the water source is prevented from being dispersed and shortening the spraying distance; the arc surface of the reset piece 65 drives the hinged plate 66 to move toward the center of the atomizer gun 56 and reset, and the hinged plate 66 swings downward and resets due to the impact pressure of the water source, and repeats in this way to further reduce the flow aperture on the original basis, speed up the flow rate of the water source, and avoid the twisting piece 54 from having insufficient squeezing force on the dust-cleaning water bag 55 to reduce the spraying force; the reset piece 65 drives the transmission ring 67 to move up and down, and the transmission ring 67 blocks the connection between the telescopic end of the telescopic rod 64 to prevent solid dirt from getting stuck and making it difficult for the telescopic rod 64 to freely retract.

[0032] When the convex ball of the convex ball rubber rod 44 touches the material, it slides along the outer wall of the rubber rod towards the dust suction component 43. The convex ball touches the elastic sheet 71 and deforms it. Then, the elastic sheet 71 pushes the convex ball to reset through its elastic force. When the elastic sheet 71 deforms and restores, it drives the T-shaped pressing plate 73 to roll and crush the larger dust blocked by the inner wall of the collection net plate 72, preventing the dust from directly entering the dust suction component 43 and causing damage. At the same time, the collection net plate 72 separates the solid block dust and dust, preventing them from mixing and entering the dust suction component 43. The T-shaped pressing plate 73 drives the vertical plate 74 to move left and right. When the vertical plate 74 drives the rolling wheel 75 to slide along the inner wall of the collection net plate 72, friction is generated. The rolling wheel 75 starts to rotate through the friction to roll and crush the solid block dust more finely, further improving the crushing effect of the T-shaped pressing plate 73 on the original basis and preventing the collection net plate 72 from being blocked. The T-shaped pressing plate 73 touches the arc-shaped sheet 76 and deforms and restores synchronously. When the arc-shaped sheet 76 restores, it provides power for the reset of the T-shaped pressing plate 73, preventing the reset from getting stuck. At the same time, when the arc-shaped sheet 76 deforms, it drives the knocking column 77 to reciprocally knock the inner wall of the collection net plate 72 to generate vibration and reduce the adhesion strength of the dust, preventing the dust rolled by the T-shaped pressing plate 73 from adhering to the inner wall surface of the collection net plate 72.
