Technical Field

[0001] This application relates to the technical field of road construction, and in particular to a paving device for road base construction. Background Technology

[0002] Currently, road construction is a crucial component of modern urban and rural infrastructure development, aiming to improve traffic conditions, promote economic development, and enhance residents' quality of life. With the acceleration of urbanization and the increasing demand for transportation, road construction technology has made significant progress in material selection, structural design, construction processes, and environmental protection requirements.

[0003] The cement-stabilized crushed stone paving device for road base construction in related technologies generally includes a mobile vehicle, a paving mechanism installed at one end of the mobile vehicle base, a hopper installed at the base of the mobile vehicle, a discharge pipe connected to the bottom of the hopper, and an electric slide valve installed on the discharge pipe.

[0004] However, the materials in the aforementioned silos are prone to stratification during transportation, resulting in unevenly mixed materials being laid, which can easily affect the quality of the road later. Summary of the Invention

[0005] This application provides a paving device for road base construction, which can improve the mixing uniformity of materials in the silo, and adopts the following technical solution:

[0006] A paving device for road base construction includes a mobile vehicle, a paving mechanism installed at one end of the mobile vehicle's base, a hopper installed on the mobile vehicle's base, a discharge pipe connected to the bottom of the hopper, and an electric slide valve installed on the discharge pipe. A mixing mechanism is installed inside the hopper. The mixing mechanism includes a horizontal plate fixed to the top of the hopper, a mixing motor installed on the top of the horizontal plate, a mixing shaft fixed to the output shaft of the mixing motor, and multiple mixing blades fixed to the side wall of the mixing shaft. Turning mechanisms for turning the material are installed on both sides of the hopper.

[0007] By adopting the above scheme, when it is necessary to improve the mixing uniformity of materials in the silo, the stirring motor is started first. At this time, the output shaft of the stirring motor drives the stirring shaft to rotate, and the rotation of the stirring shaft drives the stirring paddle to rotate. The rotation of the stirring paddle can improve the mixing uniformity of materials in the silo. In summary, the stirring mechanism can improve the mixing uniformity of materials in the silo. In addition, the turning mechanism facilitates the turning of materials in the silo, thereby further improving the mixing uniformity of materials in the silo.

[0008] Preferably, the turning mechanism includes a mounting frame installed on the side wall of the hopper, a reciprocating screw rotatably connected to the mounting frame, and a guide rod fixed to the mounting frame; a first gear is sleeved and fixed on the side wall of the stirring shaft, a second gear is sleeved and fixed on the reciprocating screw, the first gear and the second gear mesh, a turning plate is threadedly connected to the reciprocating screw, and the turning plate is slidably connected to the guide rod.

[0009] By adopting the above scheme, the rotation of the stirring shaft drives the first gear to rotate, the rotation of the first gear drives the second gear to rotate, the rotation of the second gear drives the reciprocating screw to rotate, and the rotation of the reciprocating screw enables the tilting plate to move back and forth, thereby facilitating the turning of the material in the hopper; in summary, the tilting mechanism is set to facilitate the turning of the material in the hopper.

[0010] Preferably, a clearing mechanism is installed above the discharge pipe on the side wall of the hopper. The clearing mechanism includes a clearing plate that slides vertically and is connected to the inner wall of the hopper, a reset component installed on the side wall of the hopper for resetting the clearing plate, and a plurality of clearing components fixed to the bottom of the clearing plate. The clearing components are movable within the discharge pipe. A drive rod is fixed to the bottom of the tilting plate. A first through hole is provided at the bottom of the mounting frame for the drive rod to pass through. The end of the drive rod away from the tilting plate abuts against the top of the clearing plate.

[0011] By adopting the above scheme, the downward movement of the tilting plate drives the drive rod to move downward, which in turn drives the unblocking plate to move downward, and the downward movement of the unblocking plate drives the unblocking component to move downward. In addition, the unblocking plate has an upward tendency under the action of the reset component. When the tilting plate moves upward, it drives the drive rod to move upward, and then the unblocking plate resets upward under the action of the reset component, which in turn drives the unblocking component to reset upward. In summary, the unblocking mechanism enables the unblocking component to move vertically within the discharge pipe, thereby facilitating the unblocking of the discharge pipe.

[0012] Preferably, the reset assembly includes a first dovetail groove formed on one side of the inner wall of the hopper, a first dovetail plate slidably connected to the first dovetail groove, and a first reset spring fixed to the top of the first dovetail plate; the first dovetail plate is fixed to one side of the unblocking plate, and elastic sealing strips are fixed to both sides of the first dovetail plate respectively; the ends of the two sealing elastic strips away from the unblocking plate are respectively fixed to the inner walls of both ends of the first dovetail groove, and the end of the first reset spring away from the first dovetail plate is fixed to the top wall of the first dovetail groove.

[0013] By adopting the above scheme, when the unblocking plate moves downward, it drives the first dovetail plate to move downward, and the downward movement of the first dovetail plate stretches the first return spring; when the tipping plate moves upward, the first dovetail plate drives the unblocking plate to return to its original position under the action of the first return spring; in summary, the reset component facilitates the upward reset of the unblocking plate; the elastic strip reduces the amount of material entering the first dovetail groove.

[0014] Preferably, each of the unblocking components includes a fixed pipe fixed to the bottom of the unblocking plate, a vertical groove formed in the inner wall of the fixed pipe, a movable plate slidably connected to the vertical groove along the vertical direction, and a vertical spring fixed to the top of the movable plate; the end of the vertical spring away from the movable plate is fixed to the top wall of the fixed pipe; a unblocking rod is rotatably connected to the bottom of the movable plate, and a conical block is fixed to the bottom of the unblocking rod; a plurality of spiral blocks are fixed to the side wall of the unblocking rod, and a plurality of spiral grooves are formed in the inner wall of the fixed pipe, with the spiral blocks corresponding to and matching the spiral grooves one by one.

[0015] By adopting the above solution, when the material below the conical block is hard, the conical block can be buffered by the action of the moving plate and the vertical spring, thereby reducing the impact force on the conical block and extending its service life. In addition, when the conical block encounters a hard object, the hard object can drive the conical block to move upward. The upward movement of the conical block drives the unblocking rod to move upward. Then, the unblocking rod rotates under the action of the spiral block and the spiral groove, which makes it easier to rotate and push the hard object away, thus facilitating the continued descent of the conical block.

[0016] Preferably, a second through hole is provided on one side of the turning plate, and an extension mechanism is installed in the second through hole. The extension mechanism includes an extension plate slidably connected to the second through hole. A spherical plate is fixedly connected to one end of the extension plate, and the spherical surface of the spherical plate matches the side wall of the stirring paddle. A rack is fixedly connected to the end of the extension plate away from the spherical plate. A second dovetail plate is fixedly connected to the top of the rack. A second dovetail groove is provided on the side wall of the second through hole for the second dovetail plate to slide. A second return spring is fixedly connected to one side of the second dovetail plate, and the end of the second return spring away from the second dovetail plate is fixedly connected to the inner wall of one end of the second dovetail groove.

[0017] By adopting the above scheme, the extended plate can increase the material agitation. When the spherical plate encounters the stirring paddle, the stirring paddle, under the action of the spherical surface of the spherical plate, drives the spherical plate to move away from the stirring paddle. The movement of the spherical plate away from the stirring paddle causes the extended plate to move away from the stirring paddle, which in turn causes the second dovetail plate to move away from the stirring paddle. At this time, the second dovetail plate presses against the second return spring. When the spherical plate separates from the stirring paddle, the second dovetail plate, under the action of the second return spring, drives the extended plate to return to its original position. In summary, the extended mechanism can increase the material agitation, thereby further improving the mixing uniformity of the material.

[0018] Preferably, a vibration mechanism for vibrating the inner wall of the hopper is installed at the end of the second through hole away from the agitator. The vibration mechanism includes a vibrating rod slidably connected to the end of the second through hole away from the agitator, a third dovetail plate fixed to the bottom of the vibrating rod, and a third return spring fixed to one end of the third dovetail plate. A third dovetail groove is provided on one side of the second through hole for the third dovetail plate to slide. The end of the third return spring away from the third dovetail plate is fixed to the inner wall of one end of the third dovetail groove. A drive assembly for driving the vibrating rod to move toward the inner wall of the hopper is installed in the second through hole.

[0019] By adopting the above scheme, the extension plate moves away from the mixing paddle, which in turn moves the rack away from the mixing paddle. Then, the rack, the drive assembly, the third dovetail plate, and the third return spring drive the vibrating rod to move back and forth. The reciprocating movement of the vibrating rod can vibrate the inner wall of the silo, thereby reducing the amount of material adhering to the inner wall of the silo and thus further improving the mixing uniformity of the material in the silo.

[0020] Preferably, the drive assembly includes a vertical shaft rotatably connected to the inner wall of the second through hole, a third gear fixed to one end of the vertical shaft, and a cam fixed to the other end of the vertical shaft; the third gear meshes with a rack, and one end of the vibrating rod abuts against the circumferential surface of the cam.

[0021] By adopting the above scheme, the extension plate moves away from the agitator, which in turn moves the rack away from the agitator. The rack moves away from the agitator, which drives the third gear to rotate. The rotation of the third gear drives the vertical shaft to rotate. The rotation of the vertical shaft drives the cam to rotate. Then, under the combined action of the third dovetail plate and the third return spring, the vibrating rod reciprocates. In summary, the drive assembly is designed to facilitate the movement of the vibrating rod towards the inner wall of the hopper.

[0022] In summary, this application has at least one of the following beneficial effects:

[0023] 1. When it is necessary to improve the mixing uniformity of materials in the silo, the stirring motor is started first. At this time, the output shaft of the stirring motor drives the stirring shaft to rotate, and the rotation of the stirring shaft drives the stirring paddle to rotate. The rotation of the stirring paddle can improve the mixing uniformity of materials in the silo. In summary, the stirring mechanism can improve the mixing uniformity of materials in the silo. In addition, the turning mechanism facilitates the turning of materials in the silo, thereby further improving the mixing uniformity of materials in the silo.

[0024] 2. The downward movement of the tilting plate drives the drive rod downward, which in turn drives the unblocking plate downward. This downward movement of the unblocking plate then drives the unblocking component downward. Additionally, the unblocking plate has an upward tendency under the action of the reset assembly. When the tilting plate moves upward, it drives the drive rod upward, and then the unblocking plate resets upward under the action of the reset assembly. This reset of the unblocking plate also drives the unblocking component to reset upward. In summary, the unblocking mechanism allows the unblocking component to move vertically within the discharge pipe, thus facilitating unblocking of the discharge pipe.

[0025] 3. The extension plate moves away from the mixing paddle, causing the rack to move away from the mixing paddle. Then, the rack, drive assembly, third dovetail plate, and third return spring drive the vibrating rod to reciprocate. The reciprocating movement of the vibrating rod can vibrate the inner wall of the hopper, thereby reducing the amount of material adhering to the inner wall of the hopper and thus further improving the mixing uniformity of the material in the hopper.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0034] This application discloses a paving device for road base construction, such as... Figure 1 and Figure 2 As shown, the device includes a mobile vehicle 1, a material spreading mechanism 11 mounted on one end of the base of the mobile vehicle 1, a hopper 2 mounted on the base of the mobile vehicle 1, a discharge pipe 21 connected to the bottom of the hopper 2, and an electric slide gate valve mounted on the discharge pipe 21. The bottom of the hopper 2 is inclined to facilitate the material in the hopper 2 to slide down to the discharge pipe 21. The bottom of the hopper 2 is embedded in the base of the mobile vehicle 1. The end of the discharge pipe 21 away from the hopper 2 passes through the base of the mobile vehicle 1 and extends toward the road surface. The electric slide gate valve includes a first electric push rod 22 mounted on the base of the mobile vehicle 1 and a slide gate valve body 23 fixed to the output end of the first electric push rod 22. The slide gate valve body 23 is connected to the discharge pipe 21. The material spreading mechanism 11 includes a second electric push rod 111 and a material spreading wheel 112 mounted on the output end of the second electric push rod.

[0035] like Figure 2 As shown, a stirring mechanism 3 is installed inside the silo 2. The stirring mechanism 3 includes a horizontal plate 31 fixed to the top of the silo 2, a stirring motor 32 installed on the top of the horizontal plate 31, a stirring shaft 33 fixed to the output shaft of the stirring motor 32, and multiple stirring paddles 34 fixed to the side wall of the stirring shaft 33. Turning mechanisms 4 for turning the material are installed on both sides of the silo 2. When it is necessary to improve the mixing uniformity of the material in the silo 2, the stirring motor 32 is started first. At this time, the output shaft of the stirring motor 32 drives the stirring shaft 33 to rotate, and the rotation of the stirring shaft 33 drives the stirring paddles to rotate, which improves the mixing uniformity of the material in the silo 2. In summary, the stirring mechanism 3 can improve the mixing uniformity of the material in the silo 2. In addition, the turning mechanism 4 facilitates the turning of the material in the silo 2, thereby further improving the mixing uniformity of the material in the silo 2.

[0036] like Figure 2 As shown, the turning mechanism 4 includes a mounting frame 41 installed on the side wall of the silo 2, a reciprocating screw 42 vertically rotatably connected to the mounting frame 41 via bearings, and a guide rod 43 vertically fixed to the mounting frame 41. A first gear 44 is sleeved and fixed on the side wall of the stirring shaft 33, and a second gear 45 is sleeved and fixed on the reciprocating screw 42. The first gear 44 and the second gear 45 mesh with each other. A turning plate 46 is threaded onto the reciprocating screw 42, and the guide rod 43 passes through the turning plate 46. The turning plate 46 slides vertically and is connected to the guide rod 43. The rotation of the stirring shaft 33 drives the first gear 44 to rotate, the rotation of the first gear 44 drives the second gear 45 to rotate, and the rotation of the second gear 45 drives the reciprocating screw 42 to rotate. The rotation of the reciprocating screw 42 enables the turning plate 46 to move back and forth, thereby facilitating the turning of materials in the silo 2. In summary, the turning mechanism 4 facilitates the turning of materials in the silo 2.

[0037] like Figure 2 and Figure 3As shown, a clearing mechanism 5 is installed on the side wall of the hopper 2 above the discharge pipe 21. The clearing mechanism 5 includes a clearing plate 51 that slides vertically and is connected to the inner wall of the hopper 2, a reset component installed on the side wall of the hopper 2 for resetting the clearing plate 51, and a plurality of clearing parts 52 that are vertically fixed to the bottom of the clearing plate 51. The clearing parts 52 can move within the discharge pipe 21. A drive rod 53 is fixed to the bottom of a flipping plate 46. A first through hole 411 is opened at the bottom of the mounting frame 41 for the drive rod 53 to slide vertically. The end of the drive rod 53 away from the flipping plate 46 abuts against the top of the clearing plate 51. The downward movement of the tilting plate 46 drives the drive rod 53 to move downward, which in turn drives the unblocking plate 51 to move downward. The downward movement of the unblocking plate 51 then drives the unblocking component 52 to move downward. In addition, the unblocking plate 51 has an upward tendency under the action of the reset component. When the tilting plate 46 moves upward, it drives the drive rod 53 to move upward. Then, the unblocking plate 51 resets upward under the action of the reset component, which in turn drives the unblocking component 52 to reset upward. In summary, the unblocking mechanism 5 enables the unblocking component 52 to move vertically within the discharge pipe 21, thereby facilitating the unblocking of the discharge pipe 21.

[0038] like Figure 2 and Figure 3 As shown, the reset assembly includes a first dovetail groove 54 formed on the inner wall of one side of the hopper 2, a first dovetail plate 55 slidably connected to the first dovetail groove 54 in a vertical direction, and a first reset spring 56 vertically fixed to the top of the first dovetail plate 55; the first dovetail plate 55 is fixed to one side of the unblocking plate 51, and elastic sealing strips 57 are vertically fixed to both sides of the first dovetail plate 55 respectively, the ends of the two sealing elastic strips away from the unblocking plate 51 are respectively fixed to the inner walls of both ends of the first dovetail groove 54, and the end of the first reset spring 56 away from the first dovetail plate 55 is fixed to the top wall of the first dovetail groove 54. When the unblocking plate 51 moves downward, it drives the first dovetail plate 55 to move downward, and the downward movement of the first dovetail plate 55 stretches the first return spring 56; when the tipping plate 46 moves upward, the first dovetail plate 55 drives the unblocking plate 51 to return to its original position under the action of the first return spring 56; in summary, the reset component facilitates the upward reset of the unblocking plate 51; the elastic strip reduces the amount of material entering the first dovetail groove 54.

[0039] like Figure 3 and Figure 4As shown, each unblocking component 52 includes a fixed pipe 521 vertically fixed to the bottom of the unblocking plate 51, a vertical groove 522 opened in the inner wall of the fixed pipe 521, a movable plate 523 vertically sliding and connected to the vertical groove 522, and a vertical spring 524 vertically fixed to the top of the movable plate 523; one end of the vertical spring 524 away from the movable plate 523 is fixed to the top wall of the fixed pipe 521; the bottom of the movable plate 523 is vertically rotatably connected to the unblocking rod 525 through a bearing, and a conical block 526 is fixed to the bottom of the unblocking rod 525; multiple spiral blocks 527 are fixed to the side wall of the unblocking rod 525, and multiple spiral grooves 528 are opened in the inner wall of the fixed pipe 521, with the spiral blocks 527 and spiral grooves 528 corresponding and matching one-to-one. When the material below the conical block 526 is hard, the moving plate 523 and the vertical spring 524 can buffer the conical block, thereby reducing the impact force on the conical block 526 and extending its service life. In addition, when the conical block 526 encounters a hard object, the hard object can drive the conical block 526 to move upward. The upward movement of the conical block 526 drives the unblocking rod 525 to move upward. Then, the unblocking rod 525 rotates under the action of the rotating block 527 and the rotating groove 528, which facilitates the rotation and pushing of the hard object away, thus facilitating the continued descent of the conical block 526.

[0040] like Figure 3 and Figure 5As shown, a second through hole 461 is horizontally opened on one side of the turning plate 46. An extension mechanism 6 is installed in the second through hole 461. The extension mechanism 6 includes an extension plate 61 that slides horizontally connected to the second through hole 461. A spherical plate 62 is fixedly connected to one end of the extension plate 61. The spherical surface of the spherical plate 62 matches the side wall of the stirring paddle 34. A rack 63 is horizontally fixedly connected to the end of the extension plate 61 away from the spherical plate 62. A second dovetail plate 64 is fixedly connected to the top of the rack 63. A second dovetail groove 65 is opened on the side wall of the second through hole 461 for the second dovetail plate 64 to slide horizontally. A second return spring 66 is horizontally fixedly connected to one side of the second dovetail plate 64. The end of the second return spring 66 away from the second dovetail plate 64 is fixedly connected to the inner wall of one end of the second dovetail groove 65. The extension plate 61 increases the material agitation. When the spherical plate 62 encounters the stirring paddle 34, the stirring paddle 34, under the action of the spherical surface of the spherical plate 62, drives the spherical plate 62 to move away from the stirring paddle 34. The movement of the spherical plate 62 away from the stirring paddle 34 causes the extension plate 61 to move away from the stirring paddle 34. The movement of the extension plate 61 away from the stirring paddle 34 causes the second dovetail plate 64 to move away from the stirring paddle 34. At this time, the second dovetail plate 64 presses against the second return spring 66. After the spherical plate 62 separates from the stirring paddle 34, the second dovetail plate 64, under the action of the second return spring 66, drives the extension plate 61 to return to its original position. In summary, the extension mechanism 6 increases the material agitation, thereby further improving the mixing uniformity of the material.

[0041] like Figure 2 , Figure 3 and Figure 5 As shown, a vibration mechanism 7 for vibrating the inner wall of the hopper 2 is installed at the end of the second through hole 461 away from the stirring paddle 34. The vibration mechanism 7 includes a vibration rod 71 that slides horizontally to the end of the second through hole 461 away from the stirring paddle 34, a third dovetail plate 72 fixed to the bottom of the vibration rod 71, and a third return spring 73 fixed to one end of the third dovetail plate 72. A third dovetail groove 74 is provided on one side of the second through hole 461 for the third dovetail plate 72 to slide horizontally. The end of the third return spring 73 away from the third dovetail plate 72 is fixed to the inner wall of one end of the third dovetail groove 74. A drive assembly for driving the vibration rod 71 to move toward the inner wall of the hopper 2 is installed in the second through hole 461. The extension plate 61 moves away from the mixing paddle 34, causing the rack 63 to move away from the mixing paddle 34. Then, the rack 63, the drive assembly, the third dovetail plate 72, and the third return spring 73 drive the vibrating rod 71 to reciprocate. The reciprocating movement of the vibrating rod 71 can vibrate the inner wall of the hopper 2, thereby reducing the amount of material adhering to the inner wall of the hopper 2, and thus further improving the mixing uniformity of the material in the hopper 2.

[0042] like Figure 5As shown, the drive assembly includes a vertical shaft 75 rotatably connected to the inner wall of the second through hole 461 via a bearing, a third gear 76 fixed to one end of the vertical shaft 75, and a cam 77 fixed to the other end of the vertical shaft 75. The third gear 76 meshes with a rack 63, and one end of the vibrating rod 71 abuts against the circumferential surface of the cam 77. The extension plate 61 moves away from the stirring paddle 34, causing the rack 63 to move away from the stirring paddle 34. The movement of the rack 63 away from the stirring paddle 34 drives the third gear 76 to rotate. The rotation of the third gear 76 drives the vertical shaft 75 to rotate. The rotation of the vertical shaft 75 drives the cam 77 to rotate. Then, under the combined action of the third dovetail plate 72 and the third return spring 73, the vibrating rod 71 reciprocates. In summary, the drive assembly facilitates the movement of the vibrating rod 71 towards the inner wall of the hopper 2.

[0043] Working principle: When it is necessary to improve the mixing uniformity of materials in silo 2, the stirring motor 32 is started first. At this time, the output shaft of the stirring motor 32 drives the stirring shaft 33 to rotate. The rotation of the stirring shaft 33 drives the stirring paddle to rotate, and the rotation of the stirring paddle can improve the mixing uniformity of materials in silo 2. In summary, the stirring mechanism 3 can improve the mixing uniformity of materials in silo 2. In addition, the turning mechanism 4 facilitates the turning of materials in silo 2, thereby further improving the mixing uniformity of materials in silo 2.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
