Description

Technical Field

[0001] The invention relates to the technical field of concrete curing, and in particular to a concrete road curing agent spraying device. Background Art

[0002] Concrete road refers to a road surface with cement concrete as the main material. Due to the particularity of concrete materials, in order to improve the coagulation and hardening ability of concrete and ensure the quality of concrete roads, after the concrete road is paved, it is necessary to spray curing agent on the surface of the concrete road. Therefore, a concrete road curing agent spraying device is needed.

[0003] The existing concrete road curing agent spraying device still has the following defects during use: 1. The existing spraying device cannot accurately control the spraying amount of the curing agent according to the travel speed during the spraying process of the curing agent. When the travel speed changes, insufficient or excessive spraying is likely to occur, resulting in uneven spraying and reducing the maintenance effect of the road surface. Before spraying, the curing agent and water need to be mixed in a certain proportion and then put into the spraying device for spraying. This method is cumbersome to operate and reduces the spraying efficiency.

[0004] 2. After concrete is laid, there will be a lot of dust and impurities on the surface. Therefore, after spraying the curing agent, the curing agent will adhere to the dust and impurities, making some of the curing agent unable to react with the road surface, and thus unable to effectively guarantee the maintenance effect. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problems that uneven spraying reduces the maintenance effect of the road surface, the proportioning and mixing operations of the curing agent and water are cumbersome, which reduces the spraying efficiency, and there is a large amount of dust and impurities on the surface of the concrete road, which makes some curing agents unable to react with the road surface, and thus cannot effectively ensure the maintenance effect. The present invention provides a concrete road curing agent spraying device.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A concrete road curing agent spraying device comprises a base frame, wherein the bottom end of the right side of the base frame is symmetrically limited and rotatably connected to a fixed roller, and the bottom end of the left side of the base frame is symmetrically limited and installed with a universal wheel, a spraying control component is arranged between the fixed roller and the inner side of the left side of the base frame, and the spraying control component is used to realize intermittent spraying of curing agent according to the rotation of the fixed roller, and a curing agent adding component is arranged above the spraying control component, and the curing agent adding component is used to realize the addition and stirring of curing agent according to the rotation of the fixed roller, and an injection frame is fixedly installed between the universal wheels at the bottom end of the left side of the base frame.

[0007] Furthermore, the air outlet slot of the jet frame is located on the left side, and the air outlet slot is tilted downward, so that the jet frame can pre-spray the road surface during the process of moving to the left.

[0008] The cam is provided with a toothed wheel which is rotatably connected to the toothed wheel and has a toothed wheel which is symmetrically fixed on the front and rear sides of the outer periphery of the outer periphery of the outer periphery of the outer periphery of the outer periphery of the inner ...

[0009] Furthermore, when the base frame is pushed to the left, the rotation generated by the fixed roller can drive the ratchet and the rotating shaft to rotate through the pulley 2 and the belt. Conversely, through the action of the pawl, the reverse rotation of the pulley 1 will not drive the ratchet and the rotating shaft to rotate. Therefore, only when it is pushed to the left, the rotation of the driving pulley 1 will drive the rotating shaft to rotate.

[0010] Furthermore, the diameter of the pulley 1 is smaller than the diameter of the pulley 2, so through the transmission ratio, the pulley 2 drives the pulley 1 to rotate at an accelerated speed through the belt.

[0011] Furthermore, the curing agent adding component includes a stirring tank, a stirring tank is fixedly installed on the top of the left side of the base frame, the stirring tank is located above the mounting cylinder, a pressure frame is fixedly installed on the bottom end of the stirring tank, the pressure frame is connected to the stirring tank, and the curing agent can be sprayed out by pressurization, the stirring tank and the central limiting rotation inside the pressure frame are connected with a rotating rod, the periphery of the rotating rod inside the stirring tank is provided with a stirring component, a connecting pipe is fixedly installed on the bottom end of the pressure frame, the rotating rod extends downward to the inside of the middle part of the mounting cylinder, a bevel gear 2 is fixedly installed on the bottom end of the rotating rod, and the bevel gear 2 is meshed with the bevel gear 1, so that the bevel gear 1 can drive the bevel gear 2 to rotate when it rotates, and a medicine tank is inserted on the top of the stirring tank.

[0012] Furthermore, the stirring assembly includes a roller, the rotating rod is located at the periphery of the inner area of ​​the stirring tank and the roller is fixedly installed, the periphery of the rotating roller is evenly slidably connected with a stirring blade, and the mixing of the curing agent and water is completed by the rotation of the stirring blade, the stirring blade is located at one end of the roller and is fixedly connected with a spring between the inner wall of the roller, the upper and lower ports inside the stirring tank outside the rotating rod are slidably connected with conical plugs, and a transmission rod is transmission-connected between the conical plugs distributed up and down and the upper and lower sides of the stirring blades, one side of the transmission rod is hinged to the stirring blade, and the other side is hinged to the conical plug. Therefore, when the stirring blade moves outward, the transmission rod can pull the conical plugs on the upper and lower sides closer to the middle.

[0013] Furthermore, the inclination of the conical surface of the upper conical plug is greater than that of the lower conical plug, so that when the upper and lower conical plugs are equidistantly close to each other, the allowed passage area between the upper conical plug and the upper port inside the mixing tank is smaller than the allowed passage area between the lower conical plug and the lower port inside the mixing tank, thereby making the downward outflow of the curing agent and water greater than the downward inflow of the curing agent.

[0014] Furthermore, the bottom end of the connecting pipe is fixedly installed with the top end of the ball valve of the mounting tube, and the top end of the connecting pipe is connected with the pressurizing frame, and the bottom end is connected with the inside of the mounting tube, so that the curing agent and water inside the pressurizing frame can enter the mounting tube through the connecting pipe.

[0015] Furthermore, a push rod is fixedly installed on the top right side of the base frame to facilitate the pushing of the device. An air compressor is fixedly installed on the left side of the push rod at the top right side of the base frame. The air compressor is connected with the jet frame and the pressure frame respectively through an air pipe, which can pressurize the pressure frame and enable the jet frame to spray high-pressure gas. A water storage barrel is placed above the air compressor on the left side of the push rod. The water storage barrel is connected with the mixing tank through a water pipe, so that water can be added to the mixing tank.

[0016] The beneficial effects of the present invention are as follows: 1. In the present invention, through the design of the spray control assembly, the ball valve for controlling the spray head is controlled by the rotation of the fixed roller, so the frequency of intermittent spraying can be changed accordingly according to the speed of movement of the spray device. When the moving speed of the spray device is different, intermittent spraying at equal distances can also be achieved, thereby ensuring the uniformity of spraying and improving the maintenance effect of the road surface.

[0017] 2. The present invention, through the coordinated design of the spray control component and the curing agent adding component, can mix and transport the curing agent and water by pushing the spray device, and can adaptively adjust the transport volume according to the speed of the pushing movement. When it is necessary to stop spraying, the addition of the curing agent and the transport of the mixed solution of the curing agent and water can also be stopped. There is no need to mix the curing agent and water in a certain proportion first, which makes the operation more convenient and improves the spraying efficiency.

[0018] 3. The present invention, through the cooperation of the jet frame at the bottom of the chassis and the air compressor, can first blow away the dust and impurities on the road surface when pushing forward for spraying, thereby avoiding the interference of dust and impurities on the curing agent and ensuring the maintenance effect of the road surface.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] A concrete road curing agent spraying device according to a preferred embodiment of the present invention will be described in detail below. Figure 1-Figure 2 As shown, a concrete road curing agent spraying device comprises a base frame 1, a fixed roller 2 is connected to the bottom end of the right side of the base frame 1 for front-to-back symmetrical limited rotation, a universal wheel 3 is installed at the bottom end of the left side of the base frame 1 for front-to-back symmetrical limited rotation, a spraying control component 4 is arranged between the fixed roller 2 and the inner side of the left side of the base frame 1, the spraying control component 4 is used to realize intermittent spraying of curing agent according to the rotation of the fixed roller 2, a curing agent adding component 5 is arranged above the spraying control component 4, the curing agent adding component 5 is used to realize the addition and stirring of curing agent according to the rotation of the fixed roller 2, a jet frame 6 is fixedly installed between the universal wheels 3 at the bottom end of the left side of the base frame 1, the air outlet slot of the jet frame 6 is located on the left side, and the air outlet slot is tilted downward, so that the jet frame 6 can pre-spray the road surface during the process of advancing to the left.

[0023] A push rod 7 is fixedly installed at the top right side of the base frame 1 to facilitate the pushing of the device. An air compressor 8 is fixedly installed on the left side of the push rod 7 at the top right side of the base frame 1. The air compressor 8 is connected with the jet frame 6 and the pressurizing frame 52 through an air pipe respectively, and can pressurize the pressurizing frame 52, and can also enable the jet frame 6 to spray high-pressure gas. A water storage barrel 9 is placed above the air compressor 8 on the left side of the push rod 7. The water storage barrel 9 is connected with the mixing tank 51 through a water pipe, so that water can be added to the mixing tank 51.

[0024] Furthermore, if Figure 2-Figure 7As shown, the spray control assembly 4 includes a mounting cylinder 41, and the mounting cylinder 41 is fixedly installed on the inner side of the left side of the base frame 1. The internal limit rotation of the mounting cylinder 41 is connected to the rotating shaft 42, and ratchets 43 are symmetrically fixedly installed on the front and rear sides of the outer periphery of the rotating shaft 42. The outer periphery of the ratchet 43 is limited and rotatably connected to a pulley 44, and the internal limit elastic rotation of the pulley 44 is connected to a pawl 45, and the pawl 45 is adapted to the ratchet 43, so that the pulley 44 can only drive the rotating shaft 42 to rotate in one direction, and the center of the adjacent end of the fixed roller 2 Pulley 2 46 is fixedly installed, and a belt 47 is connected to pulley 1 44 for transmission. When the base frame 1 is pushed to the left, the rotation generated by the fixed roller 2 can drive the ratchet 43 and the rotating shaft 42 to rotate through pulley 2 46 and belt 47. Conversely, through the action of the pawl 45, the reverse rotation of pulley 1 44 will not drive the ratchet 43 and the rotating shaft 42 to rotate. Therefore, only when it is pushed to the left, the rotation of the driving pulley 1 44 will drive the rotating shaft 42 to rotate.

[0025] The diameter of pulley 1 44 is smaller than the diameter of pulley 2 46 , so through the transmission ratio, pulley 2 46 drives pulley 1 44 to rotate at an accelerated speed through belt 47 .

[0026] A nozzle 48 is evenly fixedly installed at the bottom end of the mounting cylinder 41, and a ball valve 49 is connected to the mounting cylinder 41 at a position aligned with the nozzle 48 for limited rotation, and the ball valve 49 is fixedly installed between the rotating shafts 42. The nozzle 48 is switched on and off by the rotation of the ball valve 49. A bevel gear 410 is fixedly installed on the periphery of the middle part of the rotating shaft 42, and the bevel gear 410 is located inside the mounting cylinder 41.

[0027] Furthermore, if Figure 3 , Figure 8-Figure 10 As shown, the curing agent adding component 5 includes a stirring tank 51, and the stirring tank 51 is fixedly installed on the top of the left side of the base frame 1, and the stirring tank 51 is located above the mounting barrel 41. A pressurizing frame 52 is fixedly installed on the bottom end of the stirring tank 51, and the pressurizing frame 52 is connected to the stirring tank 51, so that the curing agent can be sprayed out by pressurization. The central limiting rotation inside the stirring tank 51 and the pressurizing frame 52 is connected with a rotating rod 53, and the periphery of the rotating rod 53 inside the stirring tank 51 is provided with a stirring component 54, and a connecting pipe 55 is fixedly installed on the bottom end of the pressurizing frame 52, and the bottom end of the connecting pipe 55 is fixedly installed on the top of the ball valve 49 of the mounting barrel 41, and the top end of the connecting pipe 55 is connected to the pressurizing frame 52, and the bottom end is connected to the inside of the mounting barrel 41, so that the curing agent and water inside the pressurizing frame 52 can enter the mounting barrel 41 through the connecting pipe 55.

[0028] The rotating rod 53 extends downward to the interior of the middle part of the mounting tube 41, and a bevel gear 2 56 is fixedly mounted on the bottom end of the rotating rod 53, and the bevel gear 2 56 is meshed with the bevel gear 1 410, so that the bevel gear 1 410 can drive the bevel gear 2 56 to rotate when it rotates, and a medicine tank 57 is inserted on the top of the mixing tank 51.

[0029] Furthermore, if Fig. 9 , Fig.11 As shown, the stirring assembly 54 includes a roller 541, a rotating rod 53 is located at the periphery of the inner area of ​​the stirring tank 51 and is fixedly installed with the roller 541, and the periphery of the roller 541 is evenly slidably connected with a stirring blade 542, and the mixing of the curing agent and water is completed by the rotation of the stirring blade 542, and the stirring blade 542 is located at one end of the roller 541 and is fixedly connected with a spring 543 between the inner wall of the roller 541, and the upper and lower ports of the stirring tank 51 outside the rotating rod 53 are slidably connected with conical plugs 544, and the upper and lower sides of the conical plugs 544 distributed above and below are transmission-connected with a transmission rod 545 between the upper and lower sides of the stirring blade 542, and one side of the transmission rod 545 is hinged to the stirring blade 542, and the other side is hinged to the conical plug 544. Therefore, when the stirring blade 542 moves outward, the transmission rod 545 can pull the conical plugs 544 on the upper and lower sides to move closer to the middle.

[0030] The inclination of the conical surface of the upper conical plug 544 is greater than that of the lower conical plug 544, so that when the upper and lower conical plugs 544 are equidistantly close to each other, the allowed passage area between the upper conical plug 544 and the upper port inside the mixing tank 51 is smaller than the allowed passage area between the lower conical plug 544 and the lower port inside the mixing tank 51, thereby making the downward outflow of the curing agent and water greater than the downward inflow of the curing agent.

[0031] The working principle of the present invention is: Before spraying, the agent tank 57 containing the curing agent is fixedly plugged into the top of the mixing tank 51, and the aqueous solution is added to the water storage barrel 9, and then the base frame 1 is pushed by the push rod 7 to move the spraying device on the concrete pavement.

[0032] When the spraying device is pushed forward, the friction between the road surface and the fixed roller 2 can drive the fixed roller 2 to rotate, and the fixed roller 2 will also drive the pulley 2 46 to rotate synchronously. During the rotation of the pulley 2 46, the transmission action of the belt 47 can drive the pulley 1 44 to rotate. In the process of moving forward, the ratchet 43 and the rotating shaft 42 can be driven to rotate through the matching design of the internal pawl 45 of the pulley 1 44 and the outer ratchet 43 of the rotating shaft 42.

[0033] When the shaft 42 is pushed forward to rotate, the bevel gear 1 410 and the bevel gear 2 56 are meshed with each other, and the rotation of the shaft 42 can drive the rotating rod 53 to rotate, and then the rotating rod 53 drives the roller 541 to rotate inside the mixing tank 51. During the rotation of the roller 541, the stirring blade 542 on the outer periphery of the roller 541 will stretch the spring 543 to move outward under the action of centrifugal force, and then cooperate with the action of the transmission rods 545 on the upper and lower sides to pull the tapered plugs 544 on the upper and lower sides to move closer to the middle. When the upper tapered plug 544 moves downward, the upper port inside the mixing tank 51 can be opened, so that the curing agent inside the medicine tank 57 can enter the mixing tank 51. At the same time, the aqueous solution in the water storage barrel 9 can also enter the mixing tank 51 through the water pipe, and cooperate with the rotation of the stirring blade 542 driven by the roller 541 to stir and mix the curing agent and water.

[0034] After the curing agent and water are mixed, the lower conical plug 544 moves upward when closing, and the port at the bottom of the stirring tank 51 can be opened, so that the mixed solution of the curing agent and water can enter the pressure frame 52 downward, and then be transported to the installation cylinder 41 through the connecting pipe 55, and finally be sprayed downward through the nozzle 48 at the bottom end of the installation cylinder 41 to complete the spraying, making the loading of the curing agent and water more convenient, and no need for pre-stirring and mixing, and the outward movement of the stirring blade 542 under the action of centrifugal force controls the movement of the conical plug 544. When the forward pushing speed is faster, the speed of driving the stirring blade 542 to rotate will also be faster, so that the stirring blade 542 moves outward more under the action of centrifugal force, and then the distance that the transmission rod 545 pulls the conical plug 544 to move closer to the middle will also be greater, so that the input of the curing agent and the downward outflow of the mixed solution can be increased, so as to ensure the stable transportation of the mixed solution of the curing agent and water when the pushing speed changes.

[0035] When it is necessary to turn around or adjust the position of the spraying device to move the spraying device backward, the cooperation between the internal pawl 45 of the pulley 44 and the outer ratchet 43 of the rotating shaft 42 will not drive the rotating shaft 42 to rotate. Therefore, when the spraying device moves backward or stops, the rotating rod 53 will not be driven to rotate, and the rotating roller 541 will not be driven to rotate, so that the stirring blade 542 will not be affected by the centrifugal force, and will shrink inward under the action of the spring 543, and the transmission rod 545 will push the conical plugs 544 on the upper and lower sides to move to both sides, so as to seal the upper and lower ports inside the stirring tank 51, stop the addition of the curing agent and the downward conveying of the mixed solution, and avoid waste.

[0036] While pushing the spraying device forward, start the air compressor 8, and use the air pipe to pressurize the pressurizing frame 52, so that the mixed solution can be sprayed downward, and the high-pressure gas can also be sprayed from the jet frame 6 to the road surface in front of the spraying device, so as to first remove the dust and impurities on the road surface. At the same time, the forward push can also drive the rotating shaft 42 to rotate, and then the rotating shaft 42 drives the ball valve 49 to rotate. The design of the ball valve 49 between the connecting pipe 55 and the nozzle 48 can be used to switch the delivery of the mixed solution. Therefore, during the rotation of the ball valve 49, The mixed solution can be intermittently sprayed downward from the nozzle 48 onto the road surface, and the rotation of the ball valve 49 is controlled by the rotation of the fixed roller 2. Therefore, when the pushing speed changes, the frequency of intermittent spraying will also change accordingly. When the pushing speed is different, intermittent spraying at equal distances can be achieved, thereby improving the uniformity of spraying. At the same time, when the pushing is stopped or the position is adjusted backward, the ball valve 49 can be pushed and adjusted to the closed state first, and then when the pushing is stopped or the position is adjusted backward, the ball valve 49 will no longer be driven to rotate, and then no spraying will be performed, thereby avoiding the waste of curing agent solution.

[0037] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
