Description

Technical Field

[0001] The present invention relates to the technical field of construction site dust reduction, and particularly to a lamp post type spray dust reduction device for environmental protection at construction sites. Background Technique

[0002] During the construction of the construction industry, dust is bound to occur. That is, during the construction process, a large amount of dust will be generated. If the dust is not treated for dust reduction, it will be dispersed into the external environment in large quantities. With the large-scale dispersion of dust, it will seriously endanger the lives and health of people around. Therefore, timely dust reduction treatment is required during construction.

[0003] The patent with the patent announcement number CN114733288A discloses a lamp post type spray dust reduction device for environmental protection at construction sites and its dust reduction method, including a spray assembly for carrying out dust reduction operations at a construction site and an installation assembly for installing the spray assembly. The spray assembly includes a horizontally arranged spray rack and atomizing nozzles installed on the spray rack. The installation assembly includes an installation seat and a main rod vertically arranged above the installation seat. The installation seat has an installation cavity inside, and an installation chute is opened along the vertical direction inside the main rod; wherein, the spray rack is installed on the main rod, and the spray rack can move up and down on the main rod. It also includes a driving lifting assembly for driving the spray rack to move on the main rod, and the driving lifting assembly is arranged in the installation cavity and the installation chute. This patent is applicable to dust reduction operations at construction sites, and the spray dust reduction device of this patent can adjust the spray height according to the dust situation at the construction site, improving the effect of spray dust reduction.

[0004] However, this device still has deficiencies: This device can adjust the spray height according to the actual situation of the construction site for dust reduction, but the water spraying ports of the water spraying equipment are exposed in the open-air environment of the construction site for a long time, and the water spraying ports are easily attached or blocked by the dust dispersed in the air, and the lamp post type dust reduction equipment is relatively high and not easy to maintain frequently. If this continues for a long time, it is easy to cause the dust on the water spraying ports to solidify, thereby reducing the water spraying volume. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a lamp post type spray dust reduction device for environmental protection at construction sites, which solves the problems raised in the above background technique.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A lamp post type spray dust reduction device for environmental protection at construction sites includes a base. At the center of the top of the base, an electric turntable is provided. A stabilizing frame is provided on the top of the base. The top of the conveying end of the electric turntable is provided with an electric push rod. The top of the output end of the electric push rod is provided with a working frame. At the bottom of the inner wall of the working frame, sliding rails are symmetrically provided, and a sliding frame is arranged inside the sliding rails; An anti-blocking device is arranged inside the working frame, an anti-adhesion device is arranged outside the anti-blocking device, and an anti-stuck device is arranged inside the anti-adhesion device; The anti-blocking device includes two fixed rods, which are symmetrical and fixedly installed on one side of the sliding frame close to the center of the working frame. A water supply mechanism is rotatably installed on the fixed rod close to the center of the sliding frame. The water supply mechanism is connected to and fixedly installed with a spray mechanism at the front side, and a filter plate is fixedly installed at the front side of the spray mechanism. An electric rotating rod is rotatably installed on the front side of the water supply mechanism, and the electric rotating rod passes through the outer wall of one end of the filter plate and is fixedly installed with a plurality of scrapers. The outer wall of the electric rotating rod close to one end of the filter plate is equidistantly and fixedly installed with a plurality of spoiler plates, and the inner wall of the spray mechanism is equidistantly and fixedly installed with a plurality of elastic sheets, and a knocking rod is fixedly installed on the side of the elastic sheet away from the electric rotating rod, and a protective arc shell is fixedly installed on the outer wall of the spoiler through a connecting plate.

[0007] According to the above technical scheme, a torsion spring is arranged between the water supply mechanism and the fixed rod, the front end of the electric rotating rod penetrates the inside of the filter plate, the back of the scraper contacts the front outer wall of the filter plate, the elastic sheet contacts the outer wall of the spoiler close to the side of the electric rotating rod, the end of the knocking rod away from the electric rotating rod contacts the inner wall of the spray mechanism, the outer wall of the protective arc shell contacts the inner wall of the spray mechanism, and the electric push rod is driven to rotate by the output end of the electric turntable, and the electric push rod is started. When the telescopic end of the electric push rod pushes the working frame to move upward, the working frame rotates and lifts, and then the stabilizing frame stabilizes the electric push rod during the movement, and at the same time the working frame drives the slide rail and the sliding frame to move synchronously, and the slide rail enables the sliding frame to slide horizontally inside itself, and at this time the sliding frame drives the fixed rod to move horizontally, and the fixed rod drives The water supply mechanism moves synchronously, and a water supply pipe can be installed on the back of the water supply mechanism. When the water supply mechanism moves horizontally, it will drive the spray mechanism to move synchronously, and the spray mechanism will drive the filter plate to move horizontally; start the electric rotating rod, and the electric rotating rod will drive the scraper to rotate when it rotates along the front of the water supply mechanism, and the outer wall of the filter plate will be scraped when the scraper rotates. At the same time, the electric rotating rod drives the spoiler to rotate, and the spoiler performs a revolution disturbance on the water flow flowing inside the spray mechanism. When the spoiler revolves, it will break away from the resistance to the elastic sheet. At this time, the elastic sheet will drive the knocking rod to reciprocate and knock on the inner wall of the water supply mechanism to generate vibration during the process of resetting by its own elastic force, and the filter plate will be slightly vibrated through the transmission of force, and the spoiler drives the protective arc shell to revolve inside the water supply mechanism through the connecting plate. The protective arc shell facilitates the spray to spray outward while blocking the backflow through the arc surface.

[0008] According to the above technical solution, the anti-adhesion device includes an arc panel and a trapezoidal frame, the bottom of the arc panel is fixedly installed at the bottom edge of the inner wall of the working frame, a square groove is opened on the front of the arc panel, and the top of the trapezoidal frame is fixedly installed at the bottom of the spray mechanism. The arc surface of the top of the arc panel is located on the inclined motion trajectory of the trapezoidal frame. When the spray mechanism moves forward horizontally, it drives the trapezoidal frame to move synchronously. The inclined surface of the trapezoidal frame contacts the arc surface of the top of the arc panel to generate a resistance force. As the trapezoidal frame continues to move, the spray mechanism is prompted to generate an upward movement force. At this time, the spray mechanism drives the water supply mechanism to move synchronously, and the water supply mechanism begins to flip upward along the fixed rod with its own hinge axis as the axis.

[0009] According to the above technical scheme, the anti-adhesion device also includes a hollow plate, a sliding plate, a U-shaped plate, a fixed block, a cylinder and two hinged plates. The hollow plate is fixedly installed on the outer wall of the trapezoidal frame near the center of the working frame, and the sliding plate is slidably installed on the inner wall of the working frame away from the trapezoidal frame through a spring. The bottom of the U-shaped plate is penetrated by a spring and slidably installed on the top of the sliding plate. The front side of the fixed block is fixedly installed on the back side of the U-shaped plate. The outer wall of the cylinder is fixedly installed inside the square groove of the arc panel. The two hinged plates are symmetrical and hinged at the outer wall of the cylinder.

[0010] When the cam is in motion, the U-shaped plate is moved in a direction opposite to the vertical axis of the sliding plate, and the U-shaped plate is moved in a direction opposite to the vertical axis of the sliding plate.

[0011] According to the above technical solution, the anti-stuck device includes a cover plate, an L-shaped plate, an inclined plate and a circular plate. The cover plate is fixedly installed on the outer wall of the sliding plate away from the center of the working frame, the top of the L-shaped plate is fixedly installed on the inner wall of the U-shaped plate close to the sliding plate, the bottom of the inclined plate is hinged to the side of the L-shaped plate close to the sliding plate through a torsion spring, and the top of the circular plate is fixedly installed on the bottom of the L-shaped plate.

[0012] According to the above technical solution, the cover plate is located above the sliding rail. The top of the inclined plate contacts the inner wall of the U-shaped plate, and the outer wall of the return plate contacts the outer wall of the sliding plate. When the U-shaped plate moves upward, it drives the L-shaped plate to move synchronously. The L-shaped plate drives the inclined plate to move synchronously. The inclined surface of the inclined plate always shields the connection between the U-shaped plate and the sliding plate. At the same time, the cover plate shields the sliding rail at the bottom within its movement range. And the L-shaped plate drives the return plate to slide upward along the outer wall of the sliding plate, and the return plate scrapes the outer wall of the sliding plate.

[0013] According to the above technical solution, the anti-jamming device further includes a plurality of pulleys, a reciprocating lead screw, a through frame, a vertical rod and a removal plate. A plurality of the pulleys are symmetrically and rotatably installed inside the return plate. The outer wall of the pulley contacts the outer wall of the sliding plate. Both ends of the reciprocating lead screw are fixedly installed on the side of the pulley close to the center of the return plate. The through frame is internally penetrated and movably installed on the outer wall of the reciprocating lead screw. The outer wall of the through frame is slidably connected to the inner wall of the return plate. Both ends of the vertical rod are fixedly installed inside the through frame. The removal plate is internally penetrated and hinged to the outer wall of the vertical rod through a torsion spring. The outer wall of the removal plate contacts the outer wall of the sliding plate. When the return plate drives the pulley to slide upward along the outer wall of the sliding plate, friction is generated. The pulley starts to rotate self in the return plate due to the friction. When the pulley rotates self, it drives the reciprocating lead screw to rotate. When the reciprocating lead screw rotates, through the restriction of the reciprocating spiral groove on its outer wall on the built-in block of the through frame, it prompts the through frame to be able to slide horizontally and reset along the inner wall of the return plate. The through frame drives the vertical rod to move synchronously. The vertical rod drives the removal plate to slide synchronously along the outer wall of the sliding plate to generate friction. At this time, the removal plate starts to rotate along the outer wall of the vertical rod due to the friction, that is, the removal plate contacts the outer wall of the sliding plate in the opposite direction of the movement of the vertical rod. Through the limit of the torsion spring, the removal plate can always closely adhere to the outer wall of the sliding plate for horizontal scraping, ensuring the cleanliness of the sliding plate and thus improving its service life.

[0014] The present invention provides a lamp post type spray dust reduction device for construction site environmental protection. It has the following beneficial effects: (1) Through the setting of the anti-blocking device in the present invention, through the cooperation of the fixed rod, the water supply mechanism, the spray mechanism, the filter plate, the electric rotating rod, the scraper, the spoiler, the elastic sheet, the knocking rod and the protective arc shell, relying on the filter plate to intercept the dust floating in the construction site, preventing the dust from entering the spray mechanism and adhering and blocking, avoiding the spray nozzle of the spray mechanism from solidifying due to the dust and thus reducing the water spray volume. At the same time, it is convenient to adjust the spray height and spray convenience of the spray mechanism according to the actual situation, improving the practicability; at the same time, relying on the vibration force generated when the knocking rod knocks to reduce the adhesion strength of the dust to the filter plate, thereby improving the removal speed of the dust adhered to the surface of the filter plate by the scraper. During the revolution of the scraper, the contact time between the dust and the filter plate is shortened to prevent the filter holes from being blocked and affecting the spray dust reduction. At the same time, while the spoiler revolves and the protective arc shell ensures the internal flow velocity of the spray mechanism, it prevents the dirt carried in the backflow from flowing inside the spray mechanism and polluting its interior.

[0015] (2) Through the setting of the anti-adhesion device, the present invention can continuously change the spraying angle during the movement of the spraying mechanism through the cooperation of the spraying mechanism, arc panel, trapezoidal frame, hollow plate, sliding plate, U-shaped plate, fixed block, cylinder and hinge plate, further expanding the spraying coverage range of the spraying mechanism on the original basis, which is beneficial to improving the dust reduction effect to a certain extent. At the same time, the sliding plate and the U-shaped plate are relied on to shield and protect the spraying mechanism in real time, preventing the spraying mechanism from being more easily attached by dust due to the water mist on its own surface during operation, and synchronously reducing the number of dust attachments to the spraying mechanism during idleness, reducing the maintenance frequency of the spraying mechanism in the open-air environment, further reducing the possibility of blockage of the spray nozzle of the spraying mechanism, and at the same time, the hinge plate can reduce the area of the dust invasion inside the slide rail or the working frame.

[0016] (3) Through the setting of the anti-jamming device, the present invention can, through the cooperation of the U-shaped plate, cover plate, L-shaped plate, inclined plate, return-shaped plate, pulley, reciprocating lead screw, through frame, vertical rod and removal plate, rely on the return-shaped plate to timely remove the dust attached to the surface of the sliding plate for protecting the spraying mechanism. At the same time, the cover plate effectively prevents dust from falling into the slide rail and causing the movement of the sliding frame to be blocked, and the inclined plate always guides the dust floating at the connection between the U-shaped plate and the sliding plate, preventing the U-shaped plate from being difficult to stretch during upward movement and thus reducing the protection effect on the spraying mechanism. At the same time, the friction scraping of the through frame on the whole sliding plate is divided into multiple individual scrapings, so that when the through frame contacts the solidified dirt attached to the surface of the sliding plate, there is always a scraping part in contact with the dirt rather than in a suspended posture. At the same time, relying on the setting of the removal plate and the torsion spring, the scraping frequency of the dirt on the surface of the sliding plate is increased on the original basis, and compared with the forced single scraping of the through frame, the wear phenomenon of the through frame is effectively reduced.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 of the embodiments.

[0020] Please refer to Figures 1-9 , an embodiment of the present invention is: A spray dust reduction device for a lamp post type construction site environmental protection includes a base 1. At the center of the top of the base 1, an electric turntable 2 is provided. A stabilizing frame 21 is provided at the top of the base 1. At the top of the conveying end of the electric turntable 2, an electric push rod 22 is provided. At the top of the output end of the electric push rod 22, a working frame 3 is provided. At the bottom of the inner wall of the working frame 3, slide rails 31 are symmetrically provided. Inside the slide rails 31, a sliding frame 32 is provided; An anti-blocking device 4 is provided inside the working frame 3. An anti-adhesion device 5 is provided outside the anti-blocking device 4. An anti-stuck device 6 is provided inside the anti-adhesion device 5; The anti-blocking device 4 includes two fixed rods 41. The two fixed rods 41 are symmetrically and fixedly installed on one side of the sliding frame 32 close to the center of the working frame 3. On one side of the fixed rod 41 close to the center of the sliding frame 32, a water supply mechanism 42 is rotatably installed. The front of the water supply mechanism 42 is communicatively and fixedly installed with a spraying mechanism 43. A filter plate 44 is fixedly installed on the front of the spraying mechanism 43. An electric rotating rod 45 is rotatably installed on the front of the water supply mechanism 42. On the outer wall of one end of the electric rotating rod 45 passing through the filter plate 44, a plurality of scrapers 46 are fixedly installed. At equal intervals on the outer wall of one end of the electric rotating rod 45 close to the filter plate 44, a plurality of turbulence plates 47 are fixedly installed. A plurality of elastic sheets 48 are fixedly installed at equal intervals on the inner wall of the spraying mechanism 43. On the side of the elastic sheet 48 away from the electric rotating rod 45, a knocking rod 49 is fixedly installed. The outer wall of the turbulence plate 47 is fixedly installed with a protective arc shell 410 through a connecting plate.

[0021] A torsion spring is arranged between the water supply mechanism 42 and the fixed rod 41. One end of the front of the electric rotating rod 45 penetrates inside the filter plate 44. The back of the scraper 46 contacts the front outer wall of the filter plate 44. One side of the elastic piece 48 close to the electric rotating rod 45 contacts the outer wall of the spoiler 47. One end of the knocking rod 49 far from the electric rotating rod 45 contacts the inner wall of the spraying mechanism 43. The outer wall of the protective arc shell 410 contacts the inner wall of the spraying mechanism 43. Through the above cooperation, the filter plate 44 is relied on to intercept the dust floating at the construction site, prevent the dust from entering the inside of the spraying mechanism 43 and causing adhesion and blockage phenomena, avoid the spray nozzle of the spraying mechanism 43 being solidified by the dust and thus reducing the water spray amount, and at the same time, it is convenient to adjust the spray height and spray convenience of the spraying mechanism 43 according to the actual situation, improving the practicability; through the above cooperation, the vibration force generated when the knocking rod 49 knocks is relied on to reduce the adhesion strength of the dust to the filter plate 44, thereby improving the removal speed of the dust attached to the surface of the filter plate 44 by the scraper 46. During the revolution of the scraper 46, the contact time between the dust and the filter plate 44 is shortened to prevent the filter holes from being blocked and affecting the spray dust reduction. At the same time, while the spoiler 47 revolves and the protective arc shell 410 ensure the internal flow velocity of the spraying mechanism 43, the dirt carried in the backflow is prevented from flowing inside the spraying mechanism 43 and polluting its interior.

[0022] When in use, the electric push rod 22 is driven to rotate through the output end of the electric turntable 2, and the electric push rod 22 is started. When the telescopic end of the electric push rod 22 pushes the working frame 3 to move upward, the working frame 3 is rotated and lifted. Then the stabilizing frame 21 stabilizes the electric push rod 22 during the movement. At the same time, the working frame 3 drives the slide rail 31 and the sliding frame 32 to move synchronously. The slide rail 31 enables the sliding frame 32 to slide horizontally inside itself. At this time, the sliding frame 32 drives the fixed rod 41 to move horizontally, and the fixed rod 41 drives the water supply mechanism 42 to move synchronously. The back of the water supply mechanism 42 A water supply pipe can be installed. When the water supply mechanism 42 moves horizontally, it will drive the spray mechanism 43 to move synchronously. The spray mechanism 43 drives the filter plate 44 to move horizontally. Through the above cooperation, the filter plate 44 is used to intercept the dust flying on the construction site to prevent the dust from entering the spray mechanism 43 and causing adhesion and clogging. The nozzle of the spray mechanism 43 is prevented from solidifying due to dust, thereby reducing the water spraying amount. At the same time, it is convenient to adjust the spray height and spray convenience of the spray mechanism 43 according to actual conditions, thereby improving practicality. Start the electric rotating rod 45, and the electric rotating rod 45 drives the scraper to rotate along the front of the water supply mechanism 42 The plate 46 rotates, and the scraper 46 scrapes the outer wall of the filter plate 44 when rotating. At the same time, the electric rotating rod 45 drives the spoiler 47 to rotate, and the spoiler 47 performs a revolution disturbance on the water flow flowing inside the spray mechanism 43. When the spoiler 47 revolves, it is free from the resistance to the elastic sheet 48. At this time, the elastic sheet 48 will drive the knocking rod 49 to reciprocate and knock the inner wall of the water supply mechanism 42 to generate vibration during the process of resetting by its own elastic force. The filter plate 44 is caused to vibrate slightly through the transmission of force, and the spoiler 47 drives the protective arc shell 410 to revolve inside the water supply mechanism 42 through the connecting plate, and the protective arc shell 410 facilitates the spray to be sprayed outward while blocking the backflow through the arc surface. The above cooperation relies on the vibration force generated by the knocking rod 49 when knocking to reduce the adhesion strength of dust to the filter plate 44, thereby improving the scraper 46 The speed of removing dust attached to the surface of the filter plate 44 is improved. During the revolution of the scraper 46, the contact time between the dust and the filter plate 44 is shortened to prevent the filter holes from being blocked and affecting the spray dust reduction. At the same time, the revolution of the spoiler 47 and the protective arc shell 410 ensure the internal circulation speed of the spray mechanism 43 while preventing the dirt carried in the backflow from circulating inside the spray mechanism 43 and causing pollution.

[0023] See also Figures 1-9 , based on the above embodiment, another embodiment of the present invention further includes an anti-adhesion device 5; The anti - adhesion device 5 includes an arc - shaped panel 51 and a trapezoidal frame 52. The bottom of the arc - shaped panel 51 is fixedly installed at the bottom edge of the inner wall of the working frame 3. A square groove is formed on the front surface of the arc - shaped panel 51. The top of the trapezoidal frame 52 is fixedly installed at the bottom of the spraying mechanism 43. The top arc surface of the arc - shaped panel 51 is located on the movement track of the inclined surface of the trapezoidal frame 52. Through the above cooperation, the spraying angle during the movement of the spraying mechanism 43 is continuously changed, and on the original basis, the spraying coverage range of the spraying mechanism 43 is further expanded, which is beneficial to improving the dust - reduction effect to a certain extent.

[0024] The anti - adhesion device 5 further includes a hollow plate 53, a sliding plate 54, a U - shaped plate 55, a fixing block 56, a cylinder 57 and two hinge plates 58. The hollow plate 53 is fixedly installed on the outer wall of the trapezoidal frame 52 on the side close to the center of the working frame 3. The sliding plate 54 is slidably installed on the inner wall of the working frame 3 through a spring on the side away from the trapezoidal frame 52. The bottom of the U - shaped plate 55 is penetrated and slidably installed on the top of the sliding plate 54 through a spring. The fixing block 56 is fixedly installed on the back surface of the U - shaped plate 55. The outer wall of the cylinder 57 is fixedly installed inside the square groove of the arc - shaped panel 51. The two hinge plates 58 are symmetrically hinged on the outer wall of the cylinder 57.

[0025] One side of the back surface of the sliding plate 54 is in contact with the front surface of the hollow plate 53. The U - shaped plate 55 is located above the spraying mechanism 43. The bottom of the fixing block 56 is in contact with the top of the hollow plate 53. One end of the hinge plate 58 away from the arc - shaped panel 51 is hinged on the outer wall of the sliding plate 54 through a torsion spring. Through the above cooperation, the spraying mechanism 43 is shielded and protected in real - time by relying on the sliding plate 54 and the U - shaped plate 55, preventing the spraying mechanism 43 from being more easily attached by dust due to the water mist on its own surface during operation, and synchronously reducing the number of dust attachments to the spraying mechanism 43 during idleness, reducing the maintenance frequency of the spraying mechanism 43 in the open - air environment, further reducing the possibility of the nozzle of the spraying mechanism 43 being blocked. At the same time, the hinge plate 58 can reduce the area of the slide rail 31 or the inside of the working frame 3 invaded by dust.

[0026] When in use, the spray mechanism 43 drives the trapezoidal frame 52 to move synchronously when it moves forward horizontally. The inclined surface of the trapezoidal frame 52 contacts the arc surface at the top of the arc panel 51 to generate a resistance force. As the trapezoidal frame 52 continues to move, the spray mechanism 43 generates a force to move upward. At this time, the spray mechanism 43 drives the water supply mechanism 42 to move synchronously. The water supply mechanism 42 starts to flip upward along the fixed rod 41 with its own hinge axis as the axis. The spray angle of the spray mechanism 43 is continuously changed during the movement of the spray mechanism 43 through the above cooperation. On the original basis, the spray coverage of the spray mechanism 43 is further expanded, which is beneficial to the improvement of the dust reduction effect to a certain extent. When the trapezoidal frame 52 moves horizontally, it drives the hollow plate 53 to move synchronously. The hollow plate 53 pushes the sliding plate 54 to slide synchronously along the inner wall of the working frame 3. The sliding plate 54 drives the U-shaped plate 55 to move synchronously. When the trapezoidal frame 52 moves upward, it drives the hollow plate 53 to move synchronously. The hollow plate 53 contacts the sliding plate 5 4, the fixed block 56 is pushed upward, at this time, the fixed block 56 generates an upward force and pulls the U-shaped plate 55 upward, and the sliding plate 54 will drive the hinge plate 58 to move synchronously during the sliding process, and the hinge plate 58 is limited by the cylinder 57 to cause its own hinge shaft to start rotating, and the hinge plate 58 starts to move in an arc trajectory with the hinge shaft as the axis. After the hinge plate 58 is turned over, it blocks the slide rail 31 and the inside of the work frame 3 through its own inclined surface. Through the above cooperation, the sliding plate 54 and the U-shaped plate 55 are used to block and protect the spray mechanism 43 in real time, so as to prevent the spray mechanism 43 from being more easily attached to dust due to the water mist on its surface when working, and to reduce the amount of dust attached to the spray mechanism 43 when idle, thereby reducing the maintenance frequency of the spray mechanism 43 in an open air environment, and further reducing the possibility of the spray mechanism 43 nozzle being blocked. At the same time, the hinge plate 58 can reduce the area of the slide rail 31 or the inside of the work frame 3 that is invaded by dust.

[0027] See also Figures 1-9 , based on the above embodiment, another embodiment of the present invention further includes an anti-stuck device 6; The anti-stuck device 6 includes a cover plate 61, an L-shaped plate 62, an inclined plate 63 and a circular plate 64. The cover plate 61 is fixedly installed on the outer wall of the sliding plate 54 away from the center of the working frame 3, the top of the L-shaped plate 62 is fixedly installed on the inner wall of the U-shaped plate 55 close to the sliding plate 54, the bottom of the inclined plate 63 is hinged to the side of the L-shaped plate 62 close to the sliding plate 54 through a torsion spring, and the top of the circular plate 64 is fixedly installed on the bottom of the L-shaped plate 62.

[0028] The cover plate 61 is located above the slide rail 31. The top of the inclined plate 63 contacts the inner wall of the U-shaped plate 55, and the outer wall of the return-shaped plate 64 contacts the outer wall of the sliding plate 54. Through the above cooperation, the dust attached to the surface of the sliding plate 54 due to the protective spraying mechanism 43 can be removed in time by relying on the return-shaped plate 64. At the same time, the cover plate 61 effectively prevents dust from falling into the slide rail 31 and causing obstacles to the movement of the sliding frame 32. Moreover, the inclined plate 63 always guides the dust floating at the connection between the U-shaped plate 55 and the sliding plate 54, avoiding the difficulty of stretching during the upward movement of the U-shaped plate 55 and thus reducing the protection effect on the spraying mechanism 43.

[0029] The anti-jamming device 6 further includes a plurality of pulleys 65, a reciprocating lead screw 66, a through frame 67, a vertical rod 68 and a removing plate 69. A plurality of pulleys 65 are symmetrically and rotatably installed inside the return-shaped plate 64, and the outer wall of the pulley 65 contacts the outer wall of the sliding plate 54. Both ends of the reciprocating lead screw 66 are fixedly installed on the side of the pulley 65 close to the center of the return-shaped plate 64. The through frame 67 is internally penetrated and movably installed on the outer wall of the reciprocating lead screw 66. The outer wall of the through frame 67 is slidably connected to the inner wall of the return-shaped plate 64. Both ends of the vertical rod 68 are fixedly installed inside the through frame 67. The removing plate 69 is internally penetrated and hinged to the outer wall of the vertical rod 68 through a torsion spring. The outer wall of the removing plate 69 contacts the outer wall of the sliding plate 54. Through the above cooperation, the frictional scraping of the through frame 67 on the whole sliding plate 54 is divided into multiple individual scrapings, so that when the through frame 67 contacts the cured dirt attached to the surface of the sliding plate 54, there is always a scraping component in contact with the dirt rather than a suspended posture. At the same time, relying on the setting of the removing plate 69 and the torsion spring, the scraping frequency of the dirt on the surface of the sliding plate 54 is increased on the original basis, and compared with the forced single scraping of the through frame 67, the wear phenomenon of the through frame 67 is effectively reduced.

[0030] During use, when the U-shaped plate 55 moves upward, it drives the L-shaped plate 62 to move synchronously. The L-shaped plate 62 drives the inclined plate 63 to move synchronously. The inclined surface of the inclined plate 63 always shields the connection between the U-shaped plate 55 and the sliding plate 54. At the same time, the cover plate 61 shields the slide rail 31 at the bottom within its movement range. And the L-shaped plate 62 drives the loop-shaped plate 64 to slide upward along the outer wall of the sliding plate 54. The loop-shaped plate 64 scrapes the outer wall of the sliding plate 54. Through the above cooperation, relying on the loop-shaped plate 64, the dust attached to the surface of the sliding plate 54 due to the protective spraying mechanism 43 is removed in a timely manner. At the same time, the cover plate 61 effectively prevents dust from falling into the slide rail 31 and causing the movement of the sliding frame 32 to be blocked. And the inclined plate 63 always guides the dust floating at the connection between the U-shaped plate 55 and the sliding plate 54, preventing the U-shaped plate 55 from being difficult to stretch during upward movement and reducing the protection effect on the spraying mechanism 43. When the loop-shaped plate 64 drives the pulley 65 to slide upward along the outer wall of the sliding plate 54, friction is generated. The pulley 65 starts to rotate within the loop-shaped plate 64 by the friction force. When the pulley 65 rotates, it drives the reciprocating lead screw 66 to rotate. When the reciprocating lead screw 66 rotates, through the restriction of the reciprocating spiral groove on its outer wall on the built-in block of the through frame 67, the through frame 67 can slide horizontally along the inner wall of the loop-shaped plate 64 and reset. The through frame 67 drives the vertical rod 68 to move synchronously. The vertical rod 68 drives the removal plate 69 to slide synchronously along the outer wall of the sliding plate 54 to generate friction. At this time, the removal plate 69 starts to rotate along the outer wall of the vertical rod 68 by the friction force, that is, the removal plate 69 contacts the outer wall of the sliding plate 54 in the opposite direction of the movement of the vertical rod 68. Through the limit of the torsion spring, the removal plate 69 can always closely adhere to the outer wall of the sliding plate 54 for horizontal scraping, ensuring the cleanliness of the sliding plate 54 and thus improving its service life. Through the above cooperation, the frictional scraping of the through frame 67 on the entire sliding plate 54 is divided into multiple individual scrapings, so that when the through frame 67 contacts the cured dirt attached to the surface of the sliding plate 54, there is always a scraping component in contact with the dirt rather than in a suspended posture. At the same time, relying on the setting of the removal plate 69 and the torsion spring, the scraping frequency of the dirt on the surface of the sliding plate 54 is increased on the original basis, and compared with the forced single scraping of the through frame 67, the wear phenomenon of the through frame 67 is effectively reduced.
