Description

Technical Field

[0001] The invention belongs to the technical field related to pavement maintenance, and specifically discloses a road sealant processing device for pavement maintenance. Background Art

[0002] With the continuous improvement of the speed and level of highway construction, asphalt pavements are being used more and more widely. After being opened to traffic, pavement diseases such as cracking, rutting, potholes, slurry, and bumps occur, requiring maintenance and repair of the pavement.

[0003] Existing road maintenance will apply road sealant to repair cracks and cracks. The sealant needs to be added with the following materials: Elastomer: Elastomer is the basic material of road sealant. It is usually made of polymer materials such as butyl rubber, styrene-butadiene rubber, and lithium-ion polymer. Elastomer has good elasticity and ductility, and can effectively fill road cracks and increase road durability. Curing agent: Curing agent is the curing agent of road sealant, which is responsible for curing the elastomer into a solid. Common curing agents include magnesium oxide, aluminum oxide, iron oxide and other materials; Fillers: Fillers are mainly used to fill cracks and lines in roads. Usually, fine stones, glass beads, silica sand and other materials are used. Fillers can increase the strength and durability of road sealants and improve their service life. When mixing multiple materials, the existing device cannot ensure the uniformity and consistency of the mixing when adding materials, which increases the time of material mixing and reduces the efficiency. Therefore, we need to improve this. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-Figure 6A road sealant processing device for road maintenance shown in the figure comprises a mixing tank 1, a feeding pipe 3 is connected and installed at the lower part of the mixing tank 1, a heating element is arranged outside the mixing tank 1, a bracket 5 is fixedly arranged on the upper end surface of the mixing tank 1, a motor 6 is fixedly installed on the upper end surface of the bracket 5, a rotating shaft 18 is fixedly arranged on the output end of the motor 6, a ferrule 28 is fixedly sleeved on the lower part of the rotating shaft 18, rotating rods 13 are fixedly arranged on both sides of the outer side of the ferrule 28, transmission components are arranged on the upper end surfaces of the two rotating rods 13, elastic pressing parts are arranged inside the two rotating rods 13, feeding pipes 8 are connected and installed on both sides of the upper part of the mixing tank 1, and centrifugal material throwing parts are arranged outside the two feeding pipes 8 and located in the mixing tank 1; like Figure 1 and Figure 2 As shown, the centrifugal material throwing element can quickly disperse the material added by the feed pipe 8 in the mixing tank 1 in a circumferential direction.

[0020] The heating element comprises a heating jacket 2, and the heating jacket 2 is sleeved on the outside of the mixing tank 1; After the heating jacket 2 is connected to an external power source, the interior of the mixing tank 1 can be heated to ensure the mixing of the materials.

[0021] The transmission assembly includes a gear ring 15 mounted on the upper end surfaces of two rotating rods 13. The inner wall of the mixing tank 1 is fixedly provided with an annular shell 12. The annular shell 12 is provided with an annular groove adapted to slide the rotating rod 13. Slide rods 21 are slidably inserted in the two rotating rods 13. A curved plate 20 is fixedly provided at the end of the slide rod 21. An extrusion spring 19 is sleeved on the outside of the slide rod 21 and located above the curved plate 20. like Figure 2 and Figure 5 As shown, the rotating rod 13 rotates with the installation of the clamping sleeve 28 and the rotating shaft 18 , so that the gear ring 15 can rotate inside the mixing tank 1 .

[0022] A vertical rod 34 is connected to the lower part of the rotating shaft 18 through a rotating joint. A sleeve 16 is slidably sleeved on the outer part of the vertical rod 34. A return spring 27 is arranged inside the sleeve 16 and outside the vertical rod 34. Fixing members are arranged on both sides of the outer wall of the sleeve 16. The fixing members include an inclined rod 14 fixedly installed on one side of the outer wall of the sleeve 16. A ball 29 is fixedly installed on the end of the inclined rod 14 away from the sleeve 16. The ball 29 is in active contact with the lower surface of the curved plate 20. like Figure 2 and Figure 5As shown, under the connection of the rotating joint, the rotating shaft 18 can rotate on the top of the vertical rod 34 by itself. As the rotating shaft 18 rotates, the rotating rod 13 will drive the sliding rod 21 to make a circular motion, so that the curved plate 20 can intermittently contact with the ball 29. The ball 29 and the inclined rod 14 will make the sleeve 16 move toward the lower end of the vertical rod 34, so that the scraper rod 17 can penetrate into the inside of the discharge pipe 3, and then squeeze and contact the material inside, reducing the sedimentation of the material inside the discharge pipe 3. Then, when the curved plate 20 is separated from the ball 29, the return spring 27 drives the scraper rod 17 to move upward; The curved plate 20 is bent outward at both sides in order to prevent it from being stuck when it contacts the abutting ball 29 .

[0023] The centrifugal material-spinning part includes a chuck 22 fixedly sleeved on the outside of the feed pipe 8, a movable frame 9 is rotatably mounted on the outside of the feed pipe 8 and located above the chuck 22, a centrifuge tube 10 is fixedly arranged at the lower end of the movable frame 9, a clamping block 23 is clamped at equal distances inside the centrifuge tube 10 along the circumferential direction, and a plurality of groups of clamping blocks 23 are provided with flow ports 26 inside, a clamping shaft 24 is fixedly arranged at the bottom end of the centrifuge tube 10, a spiral blade 11 is fixedly arranged on the outside of the clamping shaft 24, a gear 25 is fixedly sleeved on the outside of the clamping shaft 24 and located below the spiral blade 11, and the gear 25 is meshedly connected with the ring gear 15; like Figure 2 , Figure 3 and Figure 4 As shown, driven by the gear ring 15, the gear 25 can drive the clamping shaft 24 and the spiral blade 11 to rotate, which can not only throw the material dropped from the feed pipe 8 to various positions of the mixing tank 1 through the rotation of the centrifuge tube 10 to reduce the agglomeration of the material, but also push the material from bottom to top through the push of the spiral blade 11, further accelerating the mixing of the material; Under the connection of the movable frame 9 , the centrifuge tube 10 and the clamping shaft 24 can rotate below the feed tube 8 .

[0024] A scraper rod 17 is fixedly provided at the bottom end of the sleeve 16, and the scraper rod 17 is slidably fitted with the inner wall of the feed tube 3. Mounting seats 4 are provided at equal distances along the circumferential direction on the outside of the mixing tank 1. like Figure 2 and Figure 5 As shown, the scraper rod 17 can be flexibly extended and retracted inside the feeding tube 3 with the pressure of the sleeve 16, thereby ensuring that the materials inside the feeding tube 3 are easily precipitated and blocked inside the feeding tube 3 due to the liquid level difference during mixing, which is not conducive to the discharge of the feeding tube 3 in the later stage; The fixing of the mounting base 4 and the external locking bolts can connect the mixing tank 1 to the external support frame.

[0025] A cladding shell 31 is mounted on the top of the rotating shaft 18, and the upper end of the cladding shell 31 is connected to the top wall of the mixing tank 1 through a fixed mounting head 30. Square tubes 33 are fixedly mounted on both sides of the outer wall of the cladding shell 31. A delivery pipe 7 is installed on the top of the two groups of square tubes 33, and one end of the delivery pipe 7 extends to the outside of the mixing tank 1. Spray heads 32 are installed at equal distances in the vertical direction inside the two groups of square tubes 33. like Figure 6 As shown, the shell 31 is mounted on the outside of the rotating shaft 18 through the mounting head 30, so that the square tube 33 can face the spiral blade 11 and the clamping shaft 24 on one side. Later, the conveying pipe 7 is connected to the external water supply pipeline to flush the materials outside the spiral blade 11 and the clamping shaft 24.

[0026] Working principle: When in use, the material is added through the feed pipe 8, and the material will flow from the inside of the feed pipe 8 to the inside of the centrifuge tube 10. At this time, the motor 6 drives the rotating shaft 18 to rotate, and the rotating shaft 18 drives the two rotating rods 13 to rotate through the external clamping sleeve 28. At the same time, the sliding rod 21 and the ring gear 15 corresponding to the rotating rod 13 also rotate with it, and the ring gear 15 is engaged with the gear 25, thereby driving the clamping shaft 24, the spiral blade 11, and the centrifuge tube 10 to rotate. The spiral blade 11 can continuously transport the material inside the mixing tank 1 from bottom to top, thereby changing the direction of traditional material mixing, and promoting the rapid fusion of the material inside the mixing tank 1. The liquid medium coming down from the feed pipe 8 flows from the flow port 26 inside each group of clamping blocks 23 to the mixing tank 1 under the rotation of the rotating centrifuge tube 10. The mixing tank 1 is arranged at different positions inside the mixing tank 1, so that the added materials can be dispersed when the materials are discharged. In this way, the adhesion between the materials can be reduced, the driving burden of the rotating shaft 18 is reduced, and the mixing time is shortened. During the rotation of the rotating rod 13, the curved plate 20 at the lower end of the sliding rod 21 will be in active contact with the ball 29, so that the sleeve 16 continuously squeezes the return spring 27 below the outer side of the rotating shaft 18 to move downward, and the scraper rod 17 at the bottom end of the sleeve 16 slides and extends to the inside of the feeding pipe 3, thereby moving the internal materials, thereby avoiding the precipitation of the materials inside the feeding pipe 3 due to the liquid difference in the feeding pipe 3 during the mixing process, thereby affecting the later discharging. Finally, after the mixing operation is completed, the conveying pipe 7 is connected to the external water supply pipeline, so that multiple groups of nozzles 32 can flush the inside of the mixing tank 1.
