A driving motor is started to enable a vertical rod to rotate, when the vertical rod rotates, a rotating plate on the outer surface of the vertical rod rotates along with the vertical rod, the rotating plate interacts with a transverse plate in a gathering assembly, and along with rotation of the rotating plate, the transverse plate drives a movable plate to do reciprocating motion; in the process, when the stirring plate on one side gathers the broken stones on the edge towards the center, the stirring plate on the other side ascends due to the matching of the inclined plate and the trapezoidal plate, and the process is repeated, so that the uniform mixing degree of the materials is ensured, and the stirring efficiency is improved. Therefore, the overall mixing effect is improved.

Description

Technical Field

[0001] The present invention relates to the field of mixing of rubber asphalt and crushed stone raw materials, and particularly to a mixing device for rubber asphalt and crushed stone seal coat raw materials. Background Art

[0002] The mixing of rubber asphalt and crushed stone raw materials is a process of preparing a composite material by stirring and fusing rubber particles, asphalt and crushed stone in a specific proportion. It is mainly used for road paving. Rubber improves the flexibility and crack resistance of asphalt, making the road surface more wear-resistant and fatigue-resistant. Crushed stone provides strength and stability. The road paved with the mixture of the three can enhance the anti-slip property of the road surface, reduce noise, extend the service life of the road, and improve driving comfort and safety.

[0003] In the Chinese patent with the application number CN202011508451.8, a device for mixing rubber asphalt is disclosed, which includes a mixing tank and two mixing units. Each mixing unit includes a rotating pipe, a heat exchange pipe and a number of mixing parts. Each mixing part includes a mixing frame, a baffle, a sliding plate and a pushing plate. One end of the mixing frame is communicated with the rotating pipe, the other end of the mixing frame is hinged to the baffle, the sliding plate is slidably arranged on the mixing frame and penetrates the rotating pipe, one end of the sliding plate is hinged to the baffle, and the other end of the sliding plate can contact the heat exchange pipe. The pushing plate is fixedly connected to the sliding plate. When adopting this technical solution, it is beneficial to improve the mixing effect of crushed stone and asphalt.

[0004] During the operation of the above patent, during the mixing process of rubber asphalt and crushed stone, the liquid rubber asphalt is viscous and can cause the crushed stone to stick to each other. However, it is precisely this viscous characteristic that causes the crushed stone on the inner wall of the mixing kettle to be firmly stuck to the wall. This makes this part of the crushed stone unable to fully participate in the mixing, thereby causing the problem of uneven mixing of materials and affecting the overall mixing effect.

[0005] For this reason, we propose a mixing device for rubber asphalt and crushed stone seal coat raw materials. Summary of the Invention

Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention. Embodiment

[0021] In order to solve the technical problem of how to improve the mixing effect of rubber asphalt and gravel, as Figures 1-7 shown, the following preferred technical solutions are provided: A rubber asphalt chip seal raw material mixing device includes a mixing frame 1. A convex block 14 is fixedly installed on the lower surface of the mixing frame 1. A connecting plate 141 is fixedly installed on the inner wall of the convex block 14. A stirring component 18 for mixing raw materials is fixedly installed on the lower surface of the connecting plate 141. An agglomerating component 13 for gathering raw materials is movably arranged on the top of the mixing frame 1. A base 2 for processing crushed stones is fixedly installed on the upper surface of the mixing frame 1. A top groove 15 is opened on the top of the mixing frame 1. A trapezoidal groove 16 is opened inside the mixing frame 1. A trapezoidal plate 161 is fixedly installed on the inner wall of the trapezoidal groove 16; The stirring component 18 includes a driving motor 181 fixedly installed on the lower surface of the connecting plate 141. A rotating rod 182 is arranged at the output end of the driving motor 181. Stirring rods 183 are fixedly installed on the outer surface of the rotating rod 182. A vertical rod 184 is fixedly installed on the upper surface of the rotating rod 182. A rotating plate 185 is fixedly installed on the outer surface of the vertical rod 184; The agglomerating component 13 includes a movable plate 131 movably arranged on the top of the mixing frame 1. A rectangular groove 132 is opened on the surface of the movable plate 131. Two groups of cross plates 133 are fixedly installed on the inner wall of the rectangular groove 132. The two groups of cross plates 133 are arranged in a mirror image and offset. A vertical plate 134 is movably arranged on the outer surface of the movable plate 131. A dial plate 135 is fixedly installed on the lower surface of the vertical plate 134. The rotating plate 185 is located inside the rectangular groove 132 and is in contact with one side of one group of cross plates 133. An inclined plate 139 is arranged in a fitting manner above the vertical plate 134. The inclined plate 139 is located inside the trapezoidal groove 16. The vertical plate 134 is slidably connected to the top groove 15. By starting the driving motor 181, the rotating rod 182 can mix and stir the raw materials and rubber asphalt. When the vertical rod 184 rotates together with the rotating rod 182, the rotating plate 185 on the outer surface of the vertical rod 184 will drive the cross plate 133 to move. At this time, the moving cross plate 133 will drive the movable plate 131 and the dial plate 135 to bring the materials on the inner wall of the mixing frame 1 to the rotating rod 182. When one group of dial plates 135 brings the materials closer to the rotating rod 182, the other group will move away from the rotating rod 182 due to the movable plate 131. At this time, the inclined plate 139 will move along the gap between the trapezoidal groove 16 and the trapezoidal plate 161. The inclined plate 139 will first move obliquely upward from the inclined surface of the trapezoidal plate 161. At this time, the dial plate 135 will also rise accordingly, so as to separate from the materials being stirred. Until the inclined plate 139 reaches the vertical surface on the other side of the trapezoidal plate 161, the dial plate 135 will drive the inclined plate 139 to descend due to gravity, so that the dial plate 135 can be inserted into the materials again, waiting to drive the materials on the other half of the mixing frame 1 to the center.

[0022] A groove 136 is formed on the upper surface of the vertical plate 134. A tension spring 137 is fixedly installed at the bottom of the groove 136. A convex plate 138 is fixedly installed on the upper surface of the tension spring 137. The convex plate 138 is slidably connected to the groove 136. The lower surface of the convex plate 138 is fixedly installed with the lower surface of the inclined plate 139. When the inclined plate 139 is in the vertical plane of the trapezoidal plate 161 and moves horizontally, the right angle of the vertical plane of the trapezoidal plate 161 can be contacted by the inclined surface on one side of the inclined plate 139 through the tension spring 137, so as to squeeze the tension spring 137, enabling the dial plate 135 to insert into the material and drive the material to move. When the inclined plate 139 comes to the inclined surface of the trapezoidal plate 161, the inclined plate 139 will be ejected, and one side of the inclined plate 139 will contact the inclined surface of the trapezoidal plate 161. When the dial plate 135 is reset, the inclined plate 139 can rise along the inclined surface of the trapezoidal plate 161. Repeating this process can make the materials at the edge be repeatedly mixed. However, the existing conventional technical means is to stir through the stirring rod 183. Sometimes, a relatively long rod is additionally added to stir the peripheral materials. However, this rod also rotates, and the materials still move towards the edge during rotation.

[0023] A fixed plate 11 is fixedly installed on the outer surface of the mixing frame 1. A heating plate is fixedly installed on the top of the mixing frame 1. A base 2 is fixedly installed on the lower surface of the fixed plate 11. A feeding pipe 5 is also fixedly installed on the upper surface of the mixing frame 1. The feeding pipe 5 is located on one side of the processing component 4. A fixed plate 11 is fixedly installed on the upper surface of the base 2. The fixed plate 11 is located below the mixing frame 1. A semi-circular plate 12 is arranged on the lower surface of the mixing frame 1. An outer plate 121 is sleeved on the outer surface of the semi-circular plate 12. An inlet 17 is formed on the upper surface of the mixing frame 1. There are two groups of inlets 17. One group of inlets 17 is communicated with the base 2, and the other group of inlets 17 is communicated with the feeding pipe 5. A flow splitting groove 142 is formed on the upper surface of the connecting plate 141. A side plate 143 is fixedly installed on the other side of the convex block 14. A double-shaft motor 144 is fixedly installed on the upper surface of the side plate 143. Threaded rods 145 are arranged at both output ends of the double-shaft motor 144. The outer plate 121 is sleeved on the outer surface of the threaded rods 145. The rubber asphalt and gravel can be respectively added through the two inlets 17. Then, the heating plate can keep the inside of the mixing frame 1 always warm to prevent the asphalt from solidifying. By starting the double-shaft motor 144, the two semi-circular plates 12 can be opened simultaneously, enabling the fully mixed materials inside the mixing frame 1 to fall into the collection frame 3. However, when discharging the finished materials in the existing method, there is only one opening for discharging the materials. Since there are a large amount of materials, and the asphalt after mixing is in a liquid state and has fluidity, but the fluid asphalt also has viscosity. The conventionally opened discharge port, combined with a large amount of sticky materials, results in poor material discharge.

[0024] Specifically, after the processed crushed stones enter the inside of the mixing box 1, and after the melted rubber asphalt is added into the mixing box 1 through the feeding pipe 5, the rotating stirring rod 183 will mix the rubber asphalt with the crushed stones. Just when the rotating rod 182 drives the stirring rod 183 to mix the rubber asphalt with the crushed stones, the rotating plate 185 on the surface of the vertical rod 184 will contact one group of cross plates 133 and drive the cross plates 133 to move horizontally. When the cross plates 133 move to the right, the baffle 135 on the left will drive the crushed stones on the left half towards the center of the stirring, while the baffle 135 on the right half will move upward along the slope on the left side of the trapezoidal plate 161 due to the inclined plate 139, thus driving the baffle 135 on the right upward. When the lower surface of the inclined plate 139 moves to the upper surface of the trapezoidal plate 161, the right baffle 135 will disengage from the crushed stones and move above the crushed stones until the inclined plate 139 moves to the vertical surface on the right side of the trapezoidal plate 161, and the baffle 135 will re-insert into the crushed stones due to its weight. After the right baffle 135 inserts into the crushed stones, the rotating plate 185 will contact another group of cross plates 133, thus driving the movable plate 131 to move to the left as a whole. At this time, the inclined plate 139 on the right drives the baffle 135 to move to the left along the bottom of the trapezoidal groove 16, gathering the crushed stones on the right half towards the middle. When the movable plate 131 moves to the left as a whole, the baffle 135 on the left half, like the baffle 135 on the right half, rises and disengages from the crushed stones until the inclined plate 139 reaches the vertical surface of the trapezoidal plate 161 and then re-inserts into the crushed stones. At this time, the rotating vertical rod 184 drives the rotating plate 185 to reciprocate the horizontal movement of the movable plate 131, so that the baffle 135 gathers the crushed stones on both the left and right sides fitting against the inside of the mixing box 1 towards the middle, enabling them to be fully mixed with the rubber asphalt. After the rubber asphalt and the crushed stones are mixed, the double-shaft motor 144 is started to rotate the two threaded rods 145 simultaneously. The outer plates 121 sleeved on the outer surfaces of the threaded rods 145 will drive the semi-circular plates 12 to move to both sides respectively. Just when the semi-circular plates 12 start to move, the mixed material inside the mixing box 1 will fall into the pre-prepared collection box 3. Until all the materials inside the mixing box 1 are discharged completely, the semi-circular plates 12 will merge again to mix the next wave of rubber asphalt and crushed stones. Through the stirring of the rotating rod 182, the movable plate 131 can be driven to reciprocate horizontally, enabling the crushed stones on both sides to be fully mixed with the rubber asphalt. Thus, the degree of uniform mixing of the materials is ensured, and the overall mixing effect is improved. Embodiment

[0025] To solve the technical problem of how to further improve the mixing quality of rubber asphalt and crushed stones, as Figures 8-13 shown, the following preferred technical solutions are provided: The processing component 4 includes an outer frame 41 fixedly installed on the upper surface of the mixing frame 1. A feeding hopper 42 is fixedly installed on the upper surface of the outer frame 41. A blanking chute 421 is formed inside the feeding hopper 42. A feeding hopper 422 is fixedly installed on the upper surface of the feeding hopper 42. There are two groups of feeding hoppers 422. One group of feeding hoppers 422 is located on the upper surface of the feeding pipe 5. A turntable 43 is arranged inside the outer frame 41. The lower surface of the turntable 43 is fixedly connected to the upper surface of the vertical rod 184. A screening box 44 is fixedly installed on one side of the outer frame 41. A discharge plate 46 and a triangular guide plate 45 are fixedly installed on one side of the screening box 44. The triangular guide plate 45 is located below the discharge plate 46. A screen 47 is movably arranged inside the screening box 44. A pushing component 48 for pushing materials is fixedly installed on one side of the screening box 44. The triangular guide plate 45 is located on one side of the feeding port 17. After adding crushed stones into the blanking chute 421 through the feeding hopper 422, the blanking chute 421 will introduce the crushed stones into the screening box 44. The crushed stones entering the screening box 44 will fall onto the surface of the screen 47. Subsequently, the vibrating screen 47 will screen the crushed stones. Then, the qualified crushed stones will pass through the screen 47 and fall below the screen 47, while the unqualified crushed stones will remain on the surface of the screen 47. Subsequently, the pushing component 48 is started. The started pushing component 48 will push both the qualified and unqualified crushed stones at the same time. The qualified crushed stones will enter the feeding port 17 through the triangular guide plate 45 and finally fall into the mixing frame 1, while the unqualified crushed stones will be pushed onto the surface of the discharge plate 46 and discharged. However, the existing vibration screening only relies on a vibrator to vibrate the materials up and down. The screening path of the vertically vibrating materials is mainly in the vertical direction, which is relatively short, and the vibration method is relatively single, making it impossible to achieve an ideal screening effect.

[0026] A vertical column 431 is fixedly installed on the surface of the turntable 43. A thin plate 432 is sleeved on the outer surface of the vertical column 431. One end of the thin plate 432 is provided with a short column 433. A horizontal plate 434 is sleeved on the outer surface of the short column 433. A linkage plate 435 is sleeved on the outer surface of the horizontal plate 434. A T-shaped groove 4351 is fixedly installed on one side of the linkage plate 435. One side of the linkage plate 435 is movably connected to one side of the screen 47. Due to the fixed connection between the turntable 43 and the vertical rod 184, when the vertical rod 184 rotates, the turntable 43 will also rotate accordingly. At this time, one end of the thin plate 432 will perform a circular motion, and the other end of the thin plate 432 will drive the horizontal plate 434 to perform a horizontal motion. At this time, the thin plate 432 will drive the horizontal plate 434 to reciprocate horizontally, and the horizontal plate 434 will drive the linkage plate 435 and the screen 47 to move together. At this time, the reciprocating screen 47 will screen the crushed stones.

[0027] A slide bar 471 is fixedly installed on the upper surface of the screen 47. A T-shaped block 472 is fixedly installed at one end of the screen 47. The T-shaped block 472 is slidably connected to the T-shaped groove 4351; One side of the screening box 44 is provided with a discharge port A442, and the discharge port A442 is movably connected to the screen 47. A reciprocating groove 446 is provided at the top of the discharge port A442, and the reciprocating groove 446 is slidably arranged with the sliding rod 471. Through the reciprocating groove 446 and the sliding rod 471, the screen 47 can increase the moving direction again while reciprocating, further improving the screening effect of the screen 47. Since the length of the screen 47 is longer than the length of the discharge port A442, when the screen 47 reciprocates, the crushed stones on the surface of the screen 47 are always inside the screening box 44. However, in the existing simple up-and-down vibration method, some qualified crushed stones may still stay on the surface of the screen 47 for vibration, resulting in low screening efficiency.

[0028] A chamber 441 is provided inside the screening box 44. On the other side of the screening box 44, a discharge port A442 and a discharge port B444 are provided. The discharge port A442 is connected to the discharge plate 46, and the discharge port B444 is connected to the triangular guide plate 45. A bottom groove 445 and a discharge port B444 are provided inside the screening box 44. The chamber 441, the discharge port A442, the communication port 443, the discharge port B444, and the bottom groove 445 are all connected and communicated. Two groups of transverse grooves 447 are provided on both sides of the screening box 44. There are two groups of transverse grooves 447. One group of transverse grooves 447 is located above the communication port 443, and the other group of transverse grooves 447 is located below the communication port 443. Two groups of door grooves 4471 are provided inside the screening box 44, and the two groups of door grooves 4471 are connected and communicated with the transverse grooves 447. An L-shaped groove 4472 and a limiting groove 4473 are also provided inside the screening box 44, and the L-shaped groove 4472 and the limiting groove 4473 are connected and communicated with the transverse groove 447 above the communication port 443. Through the transverse grooves 447, two groups of crushed stones can move simultaneously when the pushing component 48 is started, and different crushed stones can be discharged through the discharge port A442 and the discharge port B444 respectively. However, in the existing situation of up-and-down vibration, one end of the screen 47 is the conveyor belt to discharge unqualified materials, and below the screen 47 is another conveyor belt to convey suitable crushed stones. Since the existing screen 47 is inclined, the crushed stones can move by gravity, but the inclined screen 47 may very likely make some qualified crushed stones also enter the surface of the conveyor belt for discharging unqualified materials, reducing the working efficiency.

[0029] The material pushing component 48 includes an electric push rod 481 fixedly installed on one side of the screening box 44. One end of the electric push rod 481 is fixedly installed with a magnetic plate A482. One side of the magnetic plate A482 is fixedly installed with a C-shaped plate 4821. An inclined groove A4822 is formed on one side of the C-shaped plate 4821. There are two groups of inclined grooves A4822. One group of inclined grooves A4822 is located at the upper end of the C-shaped plate 4821, and the other group of inclined grooves A4822 is at the lower end of the C-shaped plate 4821. An L-shaped plate 4823 is fixedly installed on the upper surface of the C-shaped plate 4821. The L-shaped plate 4823 is slidably connected with the L-shaped groove 4472. A blocking door 484 is movably arranged inside the door groove 4471. There are two groups of blocking doors 484. An inclined groove B4841 is arranged on one side of each of the two groups of blocking doors 484. The inclined groove B4841 is adapted to the inclined groove A4822. A pressure sensor is fixedly installed at the bottom of the bottom groove 445. A weighing plate 486 is fixedly installed on the upper surface of the pressure sensor. A discharge door A485 is movably arranged on the inner wall of the discharge port A442. A discharge door B487 is movably arranged on the inner wall of the discharge port B444. The inner wall of the C-shaped plate 4821 is attached to one side of the screening box 44. One end of the C-shaped plate 4821 is slidably arranged in the transverse groove 447. Through the detection of the pressure sensor, it can be detected how much the weight of this batch of qualified crushed stones is. Subsequently, the started electric push rod 481 moves the magnetic plate A482. At this time, the C-shaped plate 4821 will move together with the slope 4831. Just as the C-shaped plate 4821 moves, the inclined groove A4822 will regularly move the inclined groove B4841, so that the C-shaped plate 4821 can move normally. When the magnetic plate A482 and the push plate 483 push all the crushed stones out, during the reset process, the two groups of blocking doors 484 will fall simultaneously, allowing smaller crushed stones to enter the transverse groove 447. When the L-shaped plate 4823 moves to the outermost end following the C-shaped plate 4821, the L-shaped plate 4823 will cause the discharge door A485 to start flipping, enabling the crushed stones to be discharged from the discharge plate 46. And the magnetic plate A482 will also cause the torsion spring 488 to flip to discharge the crushed stones. When the electric push rod 481 resets, the discharge door A485 and the torsion spring 488 will also start to reset, thereby closing the discharge port A442 and the discharge port B444 to prevent accidental discharge of the crushed stones. Since there is a mixing ratio between the crushed stones and the rubber asphalt, when the existing crushed stones are mixed, a large amount of rubber asphalt is just poured into this batch of crushed stones for stirring, and then it is observed whether to supplement crushed stones or asphalt.

[0030] A magnetic plate B is provided on one side of the discharge door B487. The magnetic plate B is arranged opposite to the magnetic plate A482, and the magnetic plate A482 and the magnetic plate B repel each other magnetically. Rotating shafts are provided on both sides of the discharge door B487, and a torsion spring 488 is sleeved on the outer surface of the rotating shaft. One end of the torsion spring 488 is fixedly connected to the rotating shaft, and the other end of the torsion spring 488 is fixedly connected to the inside of the screening box 44. When the magnetic plate A482 starts to move, the discharge door B487 that repels the magnetic plate A482 will flip, thereby opening the discharge port B444 and allowing the crushed stones to be discharged. When the magnetic plate A482 moves away from the discharge door B487, the torsion spring 488 will drive the discharge door B487 to return together, thereby re-closing the discharge port B444.

[0031] Side rods 4851 are provided on both sides of the discharge door A485. A gear 4852 is fixedly installed on the outer surface of the side rod 4851. A toothed plate 4853 is arranged on the outer surface of the side rod 4851. The toothed plate 4853 meshes with the gear 4852. A limiting plate 4854 is fixedly installed on the lower surface of the toothed plate 4853. A compression spring 4855 is fixedly installed on one side of the limiting plate 4854. The toothed plate 4853 is movably arranged at the bottom of the L-shaped groove 4472. The limiting plate 4854 is movably connected to the limiting groove 4473. One end of the compression spring 4855 is fixedly installed on the inner wall of the limiting groove 4473. When the C-shaped plate 4821 starts to move, the L-shaped plate 4823 will move along the L-shaped groove 4472 until one side of the L-shaped plate 4823 contacts the toothed plate 4853 and drives the toothed plate 4853 to move together. At this time, the moving toothed plate 4853 will pull the compression spring 4855 and also drive the gear 4852 to start rotating, so that the discharge door A485 opens the discharge port A442 and allows the crushed stones to be discharged through the discharge port A442. When the L-shaped plate 4823 resets, the compression spring 4855 will drive the toothed plate 4853 to reset, thereby allowing the discharge door A485 to re-close the discharge port A442.

[0032] Specifically, when it is necessary to mix rubber asphalt and crushed stones, the crushed stones are added into the feeding chute 421. At this time, the crushed stones will roll along the feeding chute 421 into the screening box 44. Since the rotating rod 182 inside the mixing frame 1 is rotating, and because the rotating rod 182 can drive the vertical rod 184 and the turntable 43 to rotate together, when the turntable 43 starts to rotate, the thin plate 432 on the surface of the turntable 43 will move. Since one end of the thin plate 432 is movably connected to the column 431 on the surface of the turntable 43, and the other end of the thin plate 432 is movably connected to the horizontal plate 434, and due to the relationship that the horizontal plate 434 can only move in fragments, when the turntable 43 rotates, one end of the thin plate 432 will perform a circular motion, while the other end will perform a reciprocating translational motion. One end of the horizontal plate 434 is movably connected to the linkage plate 435, and the linkage plate 435 is also movably connected to the screen 47. Therefore, when the horizontal plate 434 starts to reciprocate horizontally, it drives the screen 47 to reciprocate synchronously. When the screen 47 performs a translation, the sliding rod 471 on the surface of the screen 47 will move along the reciprocating groove 446 in a curve, further improving the screening effect of the screen 47. When the screen 47 screens out the qualified crushed stones, the qualified crushed stones will fall onto the surface of the weighing plate 486. Subsequently, the weight of this batch of qualified crushed stones is detected by the pressure sensor. Then, the electric push rod 481 is started, and the electric push rod 481 drives the magnetic plate A482 to move. Since the push plate 483 is fixedly connected to the magnetic plate A482 through the C-shaped plate 4821, the push plate 483 will also move accordingly. While the C-shaped plate 4821 is moving, the inclined groove A4822 will contact the inclined groove B4841, thereby pushing the blocking door 484 upward so that the C-shaped plate 4821 can move normally. When the magnetic plate A482 gradually approaches the discharge door B487, the magnetic plate B on one side of the discharge door B487 will repel the magnetic plate A482, thereby driving the discharge door B487 to flip, allowing the qualified crushed stones to fall through the discharge port B444 into the feed port 17 and finally onto the surface of the semi-circular plate 12. The discharge door A485 will drive the toothed plate 4853 to move because the L-shaped plate 4823 contacts the toothed plate 4853, and the gear 4852 meshing with the toothed plate 4853 will drive the discharge door A485 to rotate, allowing the unqualified crushed stones to move through the discharge port A442 to the discharge plate 46 and finally be discharged. Thus, through the vibration screening of the screen 47 and the detection of the pressure sensor, the weight of the mixed crushed stones this time can be ensured, and the amount of rubber asphalt added can be further ensured, thereby improving the effect of the mixing quality of rubber asphalt and crushed stones.
