Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance, in particular to a sealant pouring device for road maintenance. Background Art

[0002] Sealant injection devices for road maintenance are generally used to fill cracks or joints in roads to prevent moisture penetration and extend the life of the road.

[0003] During use, due to the unevenness of the road surface, the fixed-height injection device cannot maintain close contact with the road surface when encountering cracks of different heights, which will cause uneven sealant injection, and some cracks will be insufficiently filled or even not injected at all.

[0004] Secondly, there are usually dust, sand, dirt and other debris in the cracks. If these foreign objects are not completely removed before pouring, the adhesion of the sealant will be significantly reduced, causing the cracks after pouring to crack again or fail quickly.

[0005] Finally, if the sealant is supplied manually, construction must be interrupted for manual refilling once the supply is insufficient. This operation reduces the continuity of construction and increases the burden on operators. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] See also Figure 1-Figure 5, a sealant pouring device for road maintenance, including a main body 1, an adaptive mechanism, a pretreatment mechanism and a pouring mechanism. The adaptive mechanism includes a spring 2, a support frame 3, a main wheel 4 and a limit block 5. The spring 2 is installed inside the main body 1 and the other end is fixedly connected to the support frame 3. The support frame 3 is installed on the main body 1 and is slidably connected to the main body 1. The main wheel 4 is installed on the support frame 3 and is rotatably connected to the support frame 3. The limit block 5 is arranged on the support frame 3 and slides inside the main body 1. The pretreatment mechanism includes a blower 6, a cleaning motor 7, a belt 8, a driving shaft 9, a driven shaft 10 and a dustproof plate 11. The blower 6 is fixedly installed inside the main body 1, the cleaning motor 7 is fixedly installed inside the main body 1, two ends of the belt 8 are respectively installed on the driving shaft 9 and the driven shaft 10, one end of the driving shaft 9 is fixedly connected to the output end of the cleaning motor 7, and the dustproof plate 11 is fixedly installed at the bottom of the main body 1.

[0031] In this embodiment, the adaptive mechanism includes a spring 2, a support frame 3, a main wheel 4 and a limit block 5. When in use, the operator pushes the main body 1, the universal wheel 18 rotates, and the main body 1 starts to move. When repairing the road, the main wheel 4 is in contact with the ground. When the ground begins to fluctuate, the main wheel 4 is subjected to force and begins to squeeze the support frame 3. At this time, the support frame 3 slides inside the main body 1 and squeezes the spring 2, and the limit block 5 on the support frame 3 slides in the limit slide groove 25, so that the perfusion mechanism can adapt to the ups and downs of the ground and will not be damaged.

[0032] In this embodiment, the pretreatment mechanism includes a blower 6, a cleaning motor 7, a belt 8, a driving shaft 9, a driven shaft 10 and a dustproof plate 11. When in use, the blower 6 is running and absorbs external air through the vent 26 on the main body 1, and then directly sprays air to the road gap that needs to be repaired to blow out the debris inside the road gap. Then the cleaning motor 7 is running, driving the driving shaft 9 to rotate, so that the belt 8 installed in the placement groove 24 of the driving shaft 9 starts to rotate, and drives the driven shaft 10 to be fixed. The base 27 rotates, and when the driven shaft 10 rotates, the rotating plate 29 rotates in the fixed base 27 and is slidably connected with the roller 28, thereby reducing the friction when the driven shaft 10 rotates. While the driving shaft 9 and the driven shaft 10 rotate, the cleaning disc 23 at the bottom cleans the debris blown out on the road, and the dustproof plate 11 installed at the bottom of the main body 1 can block the dust raised on the road, preventing the dust from floating out from the bottom of the main body 1 to block the operator's sight or affect the filling of road cracks.

[0033] In this embodiment, the filling mechanism includes a suction plate 12, a telescopic tube 13, a delivery pump 14, a filling frame 15 and a nozzle 16. When in use, the door panel 17 is opened and the rubber is poured into the storage tank 19 of the main body 1. When the storage tank 19 is filled with the rubber, the door panel 17 is closed and the delivery pump 14 starts to operate. The suction plate 12 can absorb the rubber and transfer it to the delivery pump 14 on the delivery plate of the suction plate 12. When the delivery pump 14 is running, the sealing gasket 21 installed on the delivery pipe 20 blocks the delivery pipe 20, and the rubber entering the delivery pump 14 is transferred by the delivery pump 14 to the telescopic tube 13 and sprayed onto the road gap through the nozzle 16 on the filling frame 15. When the main body 1 moves, the secondary wheel 22 on the filling frame 15 also cooperates with the support frame 3 to slide.

[0034] Example 2:

[0035] In summary, when in use, the operator pushes the main body 1, the universal wheel 18 rotates, and the main body 1 starts to move. When repairing the road, the main wheel 4 is in contact with the ground. When the ground begins to fluctuate, the main wheel 4 is subjected to force and begins to squeeze the support frame 3. At this time, the support frame 3 slides inside the main body 1 and squeezes the spring 2, and the limit block 5 on the support frame 3 slides in the limit slide groove 25, so that the filling mechanism can adapt to the fluctuation of the ground and will not be damaged. Before filling the road gap with glue, open the door at this time. The door 17 is opened, and the rubber is poured into the material storage tank 19 of the main body 1. When the rubber is poured into the material storage tank 19, the door 17 is closed, and the delivery pump 14 starts to operate, and the suction plate 12 can absorb the rubber and transmit it to the delivery pump 14 on the delivery pipe 20 of the suction plate 12. When the delivery pump 14 is running, the sealing gasket 21 installed on the delivery pipe 20 blocks the delivery pipe 20, and the rubber entering the delivery pump 14 is transferred to the telescopic tube 13 by the delivery pump 14, and the rubber is discharged through the delivery pump 14. The nozzle 16 on the injection frame 15 sprays the glue onto the road gap, and when the main body 1 moves, the auxiliary wheel 22 on the injection frame 15 also slides with the support frame 3. Before the road gap is repaired, the blower 6 runs and absorbs the outside air through the vent 26 on the main body 1, and then directly sprays the road gap to be repaired to blow out the debris inside the road gap. Then the cleaning motor 7 runs, driving the driving shaft 9 to rotate, so that the belt 8 installed in the placement groove 24 of the driving shaft 9 starts to rotate, and drives the driven shaft 10 The rotating plate 29 rotates in the fixed base 27. When the driven shaft 10 rotates, the rotating plate 29 rotates in the fixed base 27 and is slidably connected to the roller 28, thereby reducing the friction when the driven shaft 10 rotates. While the driving shaft 9 and the driven shaft 10 rotate, the cleaning disc 23 at the bottom cleans the debris blown off the road, and the dust plate 11 installed at the bottom of the main body 1 can block the dust raised on the road, preventing the dust from floating out from the bottom of the main body 1 and blocking the operator's vision or affecting the filling of road cracks. (The driving shaft 9 and the driven shaft 10 in this device rotate in the same direction, so that foreign objects can be pushed to one side, and foreign objects (stones) will not be bounced off due to reverse rotation, thereby affecting road repair.)

[0036] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
