[0020] Next, the technical solution of a cement blanket laying device based on an automatic control system in the embodiments of the present invention will be clearly and completely described in conjunction with the 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0021] As Figures 1-10 shown, the present invention adopts the following technical solution of a cement blanket laying device based on an automatic control system: including a frame 10, and further including: traveling wheels 11 controlled by a cabinet 12 and arranged on the frame 10, and a placement rack 13 on which a cement blanket main body 14 is installed is arranged on the frame 10; A rolling mechanism 20 arranged on the frame 10, the rolling mechanism 20 includes a pair of mounting frames 21 fixedly installed on the frame 10, a first pressing roller 22 is rotatably installed on the mounting frame 21, a slider 23 is slidably installed on the mounting frame 21, a second pressing roller 24 is rotatably installed in the slider 23, a first spring 25 is fixedly installed on the slider 23, and the other end of the first spring 25 is fixedly connected to the mounting frame 21; A watering mechanism 30 arranged on the frame 10, which can cooperate with the adjusting component 40 to uniformly spray water on the cement blanket main body 14 after being rolled by the first pressing roller 22 and the second pressing roller 24.

[0022] The cement blanket main body 14 is unfolded from the placement rack 13, and the starting end of the cement blanket main body 14 is passed through between the first pressing roller 22 and the second pressing roller 24. When the cabinet 12 controls the rotation of the walking wheels 11 to drive the device to move, the first pressing roller 22 and the second pressing roller 24 first roll press the cement blanket main body 14, which can make the cement blanket main body 14 be pushed out smoothly and flatly. It should be noted that the second pressing roller 24 realizes elastic pressing through the slider 23 and the first spring 25, so as to adapt to the cement blanket main body 14 with different thicknesses. At the same time, the first spring 25 buffers to avoid damaging the cement blanket main body 14 due to excessive pressure and improve the laying flatness.

[0023] The rolling mechanism 20 further includes a rotating frame 26 rotatably installed on the mounting frame 21, and a repressing roller 27 for repressing the cement blanket main body 14 is rotatably installed on the rotating frame 26; After the initial rolling of the first pressing roller 22 and the second pressing roller 24, the repressing roller 27 drives and presses down under gravity to perform secondary rolling on the cement blanket main body 14, further eliminating air bubbles and compacting the blanket body, improving the laying density and uniformity, especially suitable for compacting thick cement blanket main bodies 14 or complex terrains.

[0024] A guide plate 28 is fixedly installed on the frame 10, and the guide plate 28 is arranged in a V shape; when the device moves, the V-shaped guide plate 28 first contacts the ground, and the sundries on the forward path of the device are discharged to both sides through the guide plate 28, so as to avoid impurities being located at the bottom of the cement blanket main body 14 and affecting the flat laying of the cement blanket main body 14.

[0025] The watering mechanism 30 includes a placement plate 31 fixedly installed on the frame 10, a water tank 32 is arranged on the placement plate 31, an extension frame 33 is fixedly installed on the frame 10, a pair of chutes 34 are opened on the extension frame 33, sliding rods 35 are slidably installed in the chutes 34, spray heads 36 are fixedly installed on the sliding rods 35, a connecting pipe 37 is fixedly installed on the spray heads 36, and one end of the connecting pipe 37 away from the spray head 36 is fixedly connected to the water tank 32 through a water pump; The rolled cement blanket main body 14 needs to be sprayed with water to accelerate hardening. After the water pump is started, the water flows out of the spray heads 36 through the connecting pipe 37. It should be noted that the staggered spray heads 36 can achieve uniform water spraying to a certain extent, and the water tank 32 provides continuous water source to ensure the continuity of the water spraying process, promote the full hardening of the cement blanket main body 14, and avoid local dry cracking.

[0026] The adjusting mechanism includes a motor 41 fixedly installed on the extension frame 33. A contact plate 42 is fixedly installed on the output shaft of the motor 41. A chamfer is provided at one end of the sliding rod 35 close to the motor 41. The contact plate 42 is matched with the chamfer. A bottom frame 43 is fixedly installed on the extension frame 33. Second springs 44 are fixedly installed at the other ends of the sliding rods 35. The ends of the second springs 44 away from the sliding rods 35 are fixedly connected to the bottom frame 43; The motor 41 drives the contact plate 42 to rotate. The edge of the contact plate 42 periodically presses the chamfered end of the sliding rod 35, pushing the sliding rod 35 to slide in the chute 34. The second spring 44 is compressed to store elastic potential energy. After the contact plate 42 rotates away, the spring releases the potential energy to push the sliding rod 35 to reset. The elastic action of the spring makes the sliding rod 35 slide smoothly. The sliding rod 35 drives the sprinkler head 36 to move left and right, so that the spraying range fully covers the cement blanket main body 14 below, further improving the spraying uniformity and the laying efficiency of the cement blanket main body 14.

[0027] A mixing assembly 50 is arranged in the sprinkler head 36. The mixing assembly 50 includes a cross bar 51 fixedly installed in the sprinkler head 36. A rotating shaft 52 is rotatably installed on the cross bar 51. A spiral stirring bar 53 is fixedly installed on the rotating shaft 52; Retarding agents are usually added to the water tank 32 to assist the further rapid hardening of the cement blanket main body 14. When the water flows through the sprinkler head 36, it impacts the spiral stirring bar 53 to make it rotate. The spiral structure of the spiral stirring bar 53 disturbs the water flow, further mixing the water and the retarding agent evenly, and also making the sprayed water more uniform and fine, improving the efficiency.

[0028] An air blowing assembly 60 is arranged on the double pressing roller 27, which can further evenly distribute the water on the cement blanket main body 14. The air blowing assembly 60 includes an elastic membrane fixedly installed in the double pressing roller 27. A number of air holes 61 are provided on the double pressing roller 27 and are matched with the elastic membrane. A pressing rod 63 is movably arranged in the double pressing roller 27; When the double pressing roller 27 rolls, the pressing rod 63 rotates with the roller body and periodically presses the elastic membrane 62. The elastic membrane 62 is deformed under pressure and ejects air flow onto the surface of the cement blanket main body 14 through the air holes 61. The flexible pressing of the elastic membrane 62 generates pulsed air blowing. The air flow impact further enables the water to evenly cover the cement blanket main body 14, further improving the laying quality.

[0029] A plug block 64 is slidably installed in the air hole 61. An elastic strip 65 is fixedly installed on the plug block 64. The other end of the elastic strip 65 is fixedly connected to the inner wall of the air hole 61. An air inlet gap is provided between the plug block 64 and the air hole 61, which does not affect the movement of the plug block 64 driven by the compression of the elastic membrane 62. The diameter of the air inlet hole 61 is smaller than that of the air hole 61; When the elastic membrane 62 is compressed, the internal air pressure increases, pushing the plug 64 to move out of the air hole 61 against the tension of the elastic strip 65, opening the air outlet channel, and the air flow is ejected. When the elastic membrane 62 returns to its original state, the internal air pressure decreases, and the elastic strip 65 pulls the plug 64 back to its original position. The outside air enters the double-compression roller 27 through the air intake gap to supplement the air source, which can prevent sundries from being sucked into the double-compression roller 27 along the air hole 61 and also prevent impurities from blocking the air hole 61.

[0030] Working principle: The cement blanket main body 14 is unfolded from the placement rack 13, and the starting end of the cement blanket main body 14 is passed through between the first roller 22 and the second roller 24. When the cabinet 12 controls the rotation of the traveling wheels 11 to drive the device to move, the cement blanket main body 14 is first rolled by the first roller 22 and the second roller 24, which can make the cement blanket main body 14 be pushed out smoothly and flatly. It should be noted that the second roller 24 realizes elastic pressing through the slider 23 and the first spring 25 to adapt to the cement blanket main bodies 14 with different thicknesses. At the same time, the first spring 25 buffers to avoid excessive pressure from damaging the cement blanket main body 14 and improves the laying flatness. After the preliminary rolling of the first roller 22 and the second roller 24, the double-compression roller 27 drives and presses down due to gravity to perform secondary rolling on the cement blanket main body 14, further eliminating air bubbles and compacting the blanket body, improving the laying density and uniformity, especially suitable for the compaction of thick cement blanket main bodies 14 or complex terrains. When the device moves, the V-shaped guide plate 28 first contacts the ground, and the sundries on the forward path of the device are discharged to both sides through the guide plate 28 to prevent impurities from being located at the bottom of the cement blanket main body 14 and affecting the flat laying of the cement blanket main body 14. The rolled cement blanket main body 14 needs to be sprayed with water to accelerate hardening. After the water pump is started, the water flows out from the spray head 36 through the connecting pipe 37. It should be noted that the spray heads 36 arranged in a staggered manner can achieve uniform water spraying to a certain extent. The water tank 32 provides a continuous water source to ensure the continuity of the water spraying process, promotes the full hardening of the cement blanket main body 14, and avoids local dry cracking. The motor 41 drives the abutting plate 42 to rotate. The edge of the abutting plate 42 periodically presses the chamfered end of the sliding rod 35, pushing the sliding rod 35 to slide in the sliding groove 34. The second spring 44 is compressed to store elastic potential energy. After the abutting plate 42 rotates away, the spring releases the potential energy to push the sliding rod 35 back to its original position. The elastic action of the spring makes the sliding rod 35 slide smoothly. The sliding rod 35 drives the spray head 36 to move left and right, so that the spraying range fully covers the cement blanket main body 14 below, further improving the water spraying uniformity and the laying efficiency of the cement blanket main body 14. A quick-setting agent is usually added into the water tank 32 to assist the main body 14 of the cement blanket to further harden quickly. When water flows through the water spray head 36, it impacts the spiral stirring bar 53 to make it rotate. The spiral structure of the spiral stirring bar 53 disturbs the water flow, further mixing the water and the quick-setting agent evenly, and also making the sprayed water more uniform and fine, improving the efficiency; When the double pressing roller 27 rolls, the pressing rod 63 rotates with the roller body and periodically presses the elastic film 62. The elastic film 62 is deformed under pressure and ejects air flow to the surface of the main body 14 of the cement blanket through the air holes 61. The flexible extrusion of the elastic film 62 generates pulsed air blowing, and the air flow impact further enables the water to evenly cover the main body 14 of the cement blanket, further improving the laying quality; When the elastic film 62 is pressed, the internal air pressure increases, pushing the plug block 64 to move out of the air hole 61 against the tension of the elastic bar 65, opening the air outlet channel, and the air flow is ejected. When the elastic film 62 returns to its original state, the internal air pressure decreases, and the elastic bar 65 pulls the plug block 64 back to its original position. The outside air enters the double pressing roller 27 through the air intake gap to supplement the air source, which can prevent sundries from being sucked into the double pressing roller 27 along the air hole 61 and also prevent impurities from blocking the air hole 61.
