Description

Technical Field

[0001] This utility model relates to the field of crack filling machine technology, specifically a crack filling machine with rapid material dispensing function. Background Technology

[0002] Highway maintenance typically refers to the maintenance of highway guardrails and road surfaces, and also includes the inspection and maintenance of highway structures such as bridges, tunnels, and culverts. Crack sealing machines are extremely common road surface machinery in highway maintenance, mainly used for preventive maintenance of road surface defects.

[0003] Most current crack sealing machines use open flames or heating tubes at the bottom for direct heating, resulting in low heat transfer efficiency and significant heat loss into the air. This requires a long preheating time. Furthermore, the open flame directly contacts the bottom of the material tank, causing localized overheating that burns the effective components in the sealant, reducing its performance, adhesion, and elasticity. This complicates subsequent crack sealing operations. Moreover, after crack sealing is completed, a small amount of sealant often remains at the sealing port, dripping onto the ground and causing pollution to the surrounding area. This necessitates manual cleaning by staff, which is quite troublesome. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6 As shown, a grouting machine with rapid material dissolving function includes a trolley 1, a storage tank 2 placed on top of the trolley 1, a motor 3 mounted on top of the storage tank 2, a stirring paddle 4 rotatably connected inside the storage tank 2, and the bottom end of the output shaft of the motor 3 fixedly connected to the top end of the stirring paddle 4. A material dissolving shell 15 is fixed to the surface of the storage tank 2. A heating box 5 is fixed to the left side of the top of the trolley 1, the heating box 5 is filled with heat transfer oil, and heat transfer oil pumps 6 are fixed above and below the right side surface of the heating box 5, and the heat transfer oil pumps 6 are connected to the heating box 5. The right side of the heat transfer oil pumps 6 are respectively... The trolley 1 is connected to an oil inlet pipe 7 and an oil return pipe 8. Heating rods 9 are installed on the upper and lower sides of the back of the heating box 5. A feeding pump 10 is fixed on the right side of the top of the trolley 1 and is connected to the inside of the storage tank 2. A bracket 11 is fixed on the right side of the top of the trolley 1. A feed pipe 12 is connected to the right side of the feeding pump 10 and passes through the bracket 11 and is fixed to the bracket 11. The feed pipe 12 is L-shaped and a grouting nozzle 13 is installed at the end of the feed pipe 12 away from the feeding pump 10. The grouting nozzle 13 faces the ground. A receiving structure 14 is fixed on the right side of the bottom of the trolley 1.

[0016] The oil inlet pipe 7 is located to the right of the upper heat transfer oil pump 6, and the oil return pipe 8 is located to the right of the lower heat transfer oil pump 6. The right ends of both the oil inlet pipe 7 and the oil return pipe 8 penetrate the material shell 15 and extend into its interior. The heating element of the heating rod 9 penetrates the heating chamber 5 and extends into its interior. A temperature sensor 16 is installed on the back of the heating chamber 5, between the heating rods 9. The sensing head of the temperature sensor 16 penetrates into the interior of the heating chamber 5. The temperature sensor 16 works in conjunction with the heating rods 9. When the upper heat transfer oil pump 6 is turned on, the heat transfer oil pump 6... The heated heat transfer oil is drawn into the interior of the melting shell 15 through the oil inlet pipe 7. The melting shell 15 heats and melts the sealant inside the storage tank 2. The motor 3 drives the stirring paddle 4 to rotate, which uniformly melts the sealant inside the storage tank 2. The heat transfer oil pump 6 below is also turned on, and the heat transfer oil below the melting shell 15 is drawn back into the heating box 5 through the oil return pipe 8 for reheating. The temperature sensor 16 monitors the temperature of the heat transfer oil inside the heating box 5, so that the heat transfer oil inside the melting shell 15 is kept at a suitable temperature.

[0017] A thermal insulation protective pad 17 is bonded to the outer surface of the chemical shell 15. The thermal insulation protective pad 17 is an aerogel felt. The thermal insulation protective pad 17 can effectively keep the heat-conducting oil inside the chemical shell 15 warm and prevent workers from getting burned when they accidentally touch the surface of the chemical shell 15.

[0018] The receiving structure 14 includes a mounting frame 141, a cylinder 142, a movable plate 143, a slide 144, and a receiving plate 145. The mounting frame 141 is fixed to the front and rear of the right side of the bottom of the trolley 1. The cylinder 142 is fixed to the bottom of the mounting frame 141. The movable plate 143 is located on the right side of the mounting frame 141, and the output shaft of the cylinder 142 is fixedly connected to the movable plate 143. The slide 144 is formed on the right side surface of the movable plate 143. The receiving plate 145 is slidably connected to the inside of the slide 144, and the top surface of the receiving plate 145 has a groove for receiving dripping sealant. The front and rear of the left side of the receiving plate 145 are provided with slots 18. The front and rear of the right side of the inner wall of the slide 144 are fixed with blocks 19, and the blocks 19 engage with the inner wall of the slots 18. After the crack filling is completed, residue often remains at the filling location, causing a small amount of residual sealant to drip and pollute the surrounding road surface. When the crack filling machine finishes working, the cylinders 142 on both sides below will open, causing the output shaft of the cylinders 142 to push the moving plate 143 to the right, so that the receiving plate 145 moves directly below the filling nozzle 13. The sealant dripping from the filling nozzle 13 will fall into the groove on the surface of the receiving plate 145. The staff can periodically pull the receiving plate 145 out of the slide groove 144 to clean the sealant in the groove on the surface of the receiving plate 145. After cleaning, the receiving plate 145 can be inserted back into the slide groove 144, so that the locking block 19 enters the locking slot 18 to position the receiving plate 145.

[0019] The storage tank 2 has a feed inlet on one side above it, which is used by the staff to pour the sealant into the storage tank 2 and to observe whether the sealant is heated to a suitable state. The motor 3, heat transfer oil pump 6, heating rod 9, feeding pump 10 and cylinder 142 in this technical solution are all manually turned on by the staff according to the processing situation.

[0020] Working principle: First, the heating rod 9 on the back of the heating box 5 is activated to uniformly and efficiently heat the heat transfer oil encapsulated inside the heating box 5. At the same time, the temperature sensor 16 monitors the temperature of the heat transfer oil in real time. When the melting operation needs to begin, the heat transfer oil pump 6 located above is activated, pumping the high-temperature heat transfer oil in the heating box 5 into the melting shell 15 surrounding the outer wall of the storage tank 2 through the oil inlet pipe 7. The high-temperature heat transfer oil circulates in the flow channels of the melting shell 15, continuously and uniformly transferring heat through large-area heat exchange. Simultaneously, as the sealant material is fed into storage tank 2, motor 3 starts and drives the agitator 4 at the bottom of its output shaft to rotate inside storage tank 2. The agitator 4 continuously stirs and agitates the sealant, ensuring uniform heating of the sealant in all areas of storage tank 2. This also effectively prevents material deposition and agglomeration, significantly accelerating its melting rate. After heat exchange, the cooled heat transfer oil is drawn back into heating box 5 via return oil pipe 8 through another heat transfer oil pump 6 located below, for a new round of heating. A closed, efficient heat transfer oil circulation heating loop is formed. After the sealant reaches the preset melting state and optimal injection viscosity, the feed pump 10, fixed on the right side of the top of the trolley 1, is started. The feed pump 10 pumps out the melted sealant from the storage tank 2 and delivers it through the connecting pipe 12. The connecting pipe 12 is designed in an L-shape, passing through and fixed on the bracket 11. Finally, the sealant is precisely injected into the cracks in the road surface through the filling nozzle 13 installed at the end of the connecting pipe 12 and facing the ground. After the main crack filling operation is completed... Workers can activate the cylinder 142 installed at the bottom of the mounting bracket 141. The output shaft of the cylinder 142 then pushes the moving plate 143 to the right, causing the receiving plate 145, which is slidably connected in the groove 144 of the moving plate 143, to move synchronously until the receiving plate 145 and the groove on its top surface are precisely moved to the position directly below the grouting nozzle 13. At this time, the residual sealant dripping from the grouting nozzle 13 will fall completely into the groove of the receiving plate 145 and be effectively collected, thereby completing the grouting operation for the cracks in the ground.
