Technical Field

[0001] The utility model relates to the technical field of cement pavement crack treatment, in particular to a cement pavement crack filling machine. Background Art

[0002] At present, pavement refers to a layered structure paved with various road construction materials on the roadbed that directly bears vehicle loads. A good quality pavement should have sufficient strength and good stability, and its surface should meet the requirements of flatness, density and anti-slip. The pavement structure consists of a surface layer, a base layer and a cushion layer.

[0003] Among them, as cement pavement is used for a long time, cracks of varying sizes will appear on the surface. In order to prevent the cracks from continuing to expand, maintenance personnel will fill the cracks.

[0004] However, crack filling machines used in the market are prone to asphalt seeping into the cracks after filling them, causing the top of the cracks to remain concave. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] The utility model aims to provide a cement pavement crack filling machine, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cement pavement crack filling machine, comprising a mobile vehicle, a combustion boiler is fixedly installed on one side of the top of the mobile vehicle, an asphalt barrel is fixedly installed on the top of the combustion boiler, a discharge pipe is connected and installed on one side of the bottom of the asphalt barrel, a solenoid valve is fixedly installed on the discharge pipe, a collection box is fixedly installed at the bottom of the discharge pipe, and a quantitative filling mechanism is detachably installed at the bottom of the collection box;

[0007] The quantitative filling mechanism includes a limiting groove opened in the middle of the bottom of the collection box, a sealing plate slidably installed in the limiting groove, a leak-proof cover fixedly installed at the bottom of the collection box, a focusing wheel rotatably installed in the middle of the leak-proof cover, and a concave roller fixedly installed in the middle of the focusing wheel. The side wall of the collection box is fixedly installed on one side of the mobile vehicle.

[0008] As an optional solution of the technical solution of the present application, a spring is fixedly installed on the outer wall of the sealing plate, and the other side of the spring is fixedly installed on the outer wall of the collecting box, so that the sealing plate is automatically reset.

[0009] As an optional solution of the technical solution of the present application, a brake sleeve is fixedly installed on the side wall of the mobile vehicle, and a connecting steel wire is movably installed in the brake sleeve. One side of the connecting steel wire is fixedly connected to one end of the sealing plate, so that the sealing plate can be pulled.

[0010] As an optional solution to the technical solution of the present application, a trolley handle is fixedly installed on one side of the mobile vehicle, and a handle is rotatably installed on one side of the trolley handle. The outer wall of the handle is fixedly installed on the other end of the connecting wire, so that the connecting wire can be pulled.

[0011] As an optional solution of the technical solution of the present application, a booster pump is fixedly installed on the other side of the top of the mobile vehicle. The booster pump is connected to the asphalt barrel through a conduit and can pressurize the interior of the asphalt barrel.

[0012] As an optional solution of the technical solution of the present application, a gas tank is detachably installed on the top of the booster pump, and the gas tank is connected to the combustion boiler through a connecting pipe and can transport gas to the combustion boiler.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The technical solution of the present application opens the valve on the gas tank and ignites the combustion boiler to heat the asphalt barrel, so that the asphalt inside the asphalt barrel is in a high-temperature liquid state, which is convenient for penetrating into the cracks of the cement pavement. At the same time, in conjunction with a quantitative filling mechanism, as the high-temperature asphalt is introduced from the discharge pipe into the aggregate box, the operator will open the sealing plate in the limit groove and continuously introduce the asphalt inside the aggregate box into the leak-proof cover. When the mobile vehicle is pushed to move, the concentrating wheel and the concave roller inside the leak-proof cover rotate together, which can not only effectively concentrate the asphalt inside the leak-proof cover at the top of the crack, but also make the asphalt at the top of the poured crack protrude, avoiding the asphalt from penetrating into the crack and causing depression.

[0015] 2. The technical solution of the present application is that a connecting steel wire is movably installed in the brake sleeve, and one side of the connecting steel wire is fixedly connected to one end of the sealing plate. When the operator presses the handle, the handle will pull the connecting steel wire in the brake sleeve to move the sealing plate in the limiting groove, thereby guiding the asphalt in the aggregate box into the leak-proof cover. Conversely, when the operator releases the handle, the sealing plate will automatically reset through the tension of the spring, which is convenient for the operator to control the leakage of asphalt.

[0021] See also Figure 1-2 The utility model provides a technical solution: a cement pavement crack filling machine, comprising a mobile vehicle 1, a combustion boiler 11 is fixedly installed on one side of the top of the mobile vehicle 1, an asphalt barrel 12 is fixedly installed on the top of the combustion boiler 11, a discharge pipe 13 is connected and installed on one side of the bottom of the asphalt barrel 12, a solenoid valve is fixedly installed on the discharge pipe 13, a collection box 2 is fixedly installed at the bottom of the discharge pipe 13, and a quantitative filling mechanism is detachably installed at the bottom of the collection box 2;

[0022] The quantitative filling mechanism includes a limiting groove 21 opened in the middle of the bottom of the collection box 2, a sealing plate 22 slidably installed in the limiting groove 21, a leak-proof cover 24 fixedly installed at the bottom of the collection box 2, a centralizing wheel 25 rotatably installed in the middle of the leak-proof cover 24, and a concave roller 26 fixedly installed in the middle of the centralizing wheel 25. The side wall of the collection box 2 is fixedly installed on one side of the mobile vehicle 1.

[0023] In this technical solution, by opening the valve on the gas tank 41 and igniting the combustion boiler 11 to heat the asphalt barrel 12, the asphalt inside the asphalt barrel 12 is in a high-temperature liquid state, which is convenient for penetrating into the cracks in the cement pavement. At the same time, in conjunction with the quantitative filling mechanism, as the high-temperature asphalt is introduced into the aggregate box 2 from the discharge pipe 13, the operator will open the sealing plate 22 in the limit groove 21 and continuously introduce the asphalt inside the aggregate box 2 into the leak-proof cover 24. When the mobile vehicle 1 is pushed to move, the concentrating wheel 25 and the concave roller 26 inside the leak-proof cover 24 rotate together, which can not only effectively concentrate the asphalt inside the leak-proof cover 24 at the top of the crack, but also make the asphalt at the top of the poured crack protrude, avoiding the asphalt from penetrating into the crack and causing depression.

[0024] In some technical solutions, a spring 23 is fixedly installed on the outer wall of the sealing plate 22, and the other side of the spring 23 is fixedly installed on the outer wall of the collecting box 2; a brake sleeve 3 is fixedly installed on the side wall of the mobile vehicle 1, and a connecting steel wire 31 is movably installed in the brake sleeve 3, and one side of the connecting steel wire 31 is fixedly connected to one end of the sealing plate 22; a trolley handle is fixedly installed on one side of the mobile vehicle 1, and a handle 32 is rotatably installed on one side of the trolley handle, and the outer wall of the handle 32 is fixedly installed on the other end of the connecting steel wire 31.

[0025] In this technical solution, when the operator presses the handle 32, the handle 32 will pull the connecting steel wire 31 in the brake sleeve 3, causing the sealing plate 22 to move in the limiting groove 21, thereby guiding the asphalt in the aggregate box 2 into the leak-proof cover 24. Conversely, when the operator releases the handle 32, the sealing plate 22 will automatically reset itself through the pulling force of the spring 23, thereby facilitating the operator's control of asphalt leakage.

[0026] In some technical solutions, a booster pump 4 is fixedly installed on the other side of the top of the mobile vehicle 1, and the booster pump 4 is connected to the asphalt barrel 12 through a conduit.

[0027] In this technical solution, the booster pump 4 is driven to increase the pressure inside the asphalt barrel 12, so as to facilitate the discharge of the asphalt inside the asphalt barrel 12.

[0028] In some technical solutions, a gas tank 41 is detachably installed on the top of the booster pump 4, and the gas tank 41 is connected to the combustion boiler 11 through a connecting pipe.

[0029] In this technical solution, the bottom of the asphalt barrel 12 can be heated by continuously inputting gas into the combustion boiler 11 through the gas tank 41.

[0030] When a cement pavement crack filling machine is used, it should be noted that the utility model is a cement pavement crack filling machine, and each component is a universal standard part or a component known to technical personnel in this field, and its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.

[0031] When in use, first open the valve on the gas tank 41 and ignite the combustion boiler 11 to heat the asphalt barrel 12, so that the asphalt inside the asphalt barrel 12 is in a high-temperature liquid state, which is convenient for penetrating into the cracks in the cement pavement. At the same time, cooperate with the quantitative filling mechanism. After the high-temperature asphalt is introduced into the collection box 2 from the discharge pipe 13, the operator will open the sealing plate 22 in the limiting groove 21 and continuously introduce the asphalt inside the collection box 2 into the leak-proof cover 24. When pushing the mobile vehicle 1 to move, the concentrating wheel 25 and the concave roller 26 inside the leak-proof cover 24 rotate together, which can not only effectively collect the asphalt inside the leak-proof cover 24, but also effectively improve the asphalt collection efficiency. At the top of the crack, the asphalt poured on the top of the crack is convex to prevent the asphalt from penetrating into the crack and causing a depression. At the same time, a connecting steel wire 31 is movably installed in the brake sleeve 3, and one side of the connecting steel wire 31 is fixedly connected to one end of the sealing plate 22. When the operator presses the handle 32, the handle 32 will pull the connecting steel wire 31 in the brake sleeve 3 to move the sealing plate 22 in the limiting groove 21, and guide the asphalt in the aggregate box 2 into the leak-proof cover 24. Conversely, when the operator releases the handle 32, the sealing plate 22 will automatically reset through the pulling force of the spring 23, which is convenient for the operator to control the leakage of asphalt.
