[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] Referring to Figures 1 to 5 A kind of hand-pushed crack pouring machine, including T-shaped bottom plate 1, the rear end bottom of T-shaped bottom plate 1 is equipped with universal wheel 2, the front end bottom of T-shaped bottom plate 1 is equipped with two driven wheels 3, the rear end upper surface of T-shaped bottom plate 1 is fixedly connected with storage tank box 4, gas tank 7 is placed in storage tank box 4, heating assembly 5 is provided on the side of storage tank box 4 and on the front end upper surface of T-shaped bottom plate 1, and blanking assembly 6 is provided on the side of heating assembly 5;

[0026] Heating assembly 5 includes protective shell 501 fixedly installed on the front end upper surface of T-shaped bottom plate 1, heating disc 502 is installed on the bottom of protective shell 501, support ring 503 is arranged on the outside of heating disc 502 and is in abutment with the inner wall of protective shell 501, storage tank 504 is placed on the upper of support ring 503, stirring paddle 505 is arranged in storage tank 504, and stirring paddle 505 is rotatably connected with the upper cover of storage tank 504 by rotating rod 506;

[0027] It needs to be explained that the side wall of the protective shell 501 near the bottom is provided with a ventilation hole, which can ensure that air enters the space between the heating disc 502, the protective shell 501 and the gas tank 7, which is helpful for gas combustion. Secondly, the upper cover of the storage tank 504 can be detached, and the safety valve on the upper cover 504 will automatically release pressure when the storage tank pressure reaches.

[0028] The discharging assembly 6 comprises a discharging elbow 601 mounted on the side wall of the storage tank 504, and a switch 602 mounted on the discharging elbow 601. The end of the switch 602 is hingedly connected with the lower end of a pull rod 603, the upper end of the pull rod 603 is hingedly connected with one end of a pressing rod 604, the middle of the pressing rod 604 is rotatably connected with one end of a connecting plate 605, and the other end of the connecting plate 605 is fixedly connected with the surface of the protective shell 501.

[0029] The T-shaped bottom plate 1 is fixedly connected with two insertion pipes 8 at the front end, the insertion pipes 8 are inserted with adjusting pipes 9, one end of the adjusting pipes 9 is fixedly connected with the upper end of an extension pipe 10, the lower end of the extension pipe 10 is hingedly connected with the upper end of a pull plate 11, the lower end of the pull plate 11 is hingedly connected with the front end of a limiting box 12, the rear end of the limiting box 12 is hingedly connected with one end of a pulling rod 13, the other end of the pulling rod 13 is fixedly connected with a handle 14, the middle of the pulling rod 13 is slidingly connected in a limiting ring 15, and the limiting ring 15 is fixedly connected with the outer wall of the protective shell 501.

[0030] It needs to be explained that the insertion pipe 8 is threadedly connected with a fastening nut, which can tightly press the adjusting pipe 9 inserted in the insertion pipe 8.

[0031] The upper end of the rotating rod 506 is fixedly connected with a stirring handle 16.

[0032] The gas tank 7 is connected with the heating disc 502 through a pipe a 701, and the gas tank 7 is connected with the spray head 17 through a pipe b 702.

[0033] The spray head 17 is fixedly connected with the adjusting pipe 9 through an extension rod 18.

[0034] The lower end of the discharging elbow 601 of the spray head 17 is located above the limiting box 12.

[0035] The storage tank box 4 is fixedly connected with a push rod 18.

[0036] Working principle: before work, the crack pouring machine is moved to the slotting and cleaning road crack slot, so that the two sides of the limiting box 12 are located on both sides of the crack slot, and then the heating disc 502 is ignited. Under the gas supply of the gas tank 7 through the pipe a701, the heating disc 502 will continuously heat the bottom of the storage tank 504 placed on the supporting ring 503, so that the crack pouring material in the storage tank 504 is heated and warmed. While the crack pouring material is heated, the stirring handle 16 can be manually rotated to drive the stirring paddle 505 to rotate through the rotating rod 506, so as to stir the heated crack pouring material. Then stop stirring, press down the pressure rod 604, the middle of the pressure rod 604 will rotate around the rotating connection of the connecting plate 604 as a fulcrum, and the other end will drive the pull rod 603 to move upward, and then the pull rod 603 will drive the switch 602 to rotate upward and open. At this time, the crack pouring material will flow out from the end of the discharge elbow pipe 601 and flow into the cleaned road crack slot. At the same time, the nozzle 17 is supplied with gas through the pipe b702 to ignite, which can heat the crack pouring material flowing out of the discharge elbow pipe 601 again. Since the two sides of the limiting box 12 are located on both sides of the crack slot, it can prevent the crack pouring material in the crack slot from overflowing and flowing to both sides of the road. The side surface of the limiting box 12 plays a blocking role on the overflowing crack pouring material. As the operator slowly pushes the crack pouring machine to drive the limiting box 12 to move forward along the crack slot, the crack pouring material can continuously flow out of the discharge elbow pipe 601 and flow into the crack slot, completing the crack repair. Secondly, considering that the road surface will have a boss, the bottom of the limiting box 12 will be blocked by the boss when sliding forward on the ground. Therefore, when encountering a boss that needs to be passed, the operator can pull the handle 14 with one hand to drive the pull rod 13 to slide in the limiting ring 15, pull the limiting box 12 and the pull plate 11 upward, and smoothly pass through the boss.

[0037] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
