Description

Technical Field

[0001] The utility model relates to the technical field of road repair, in particular to a novel road crack repairing machine. Background Art

[0002] With the continuous development of urban transportation, the quality and safety of roads have attracted much attention. Long-term use and adverse weather conditions often cause various cracks and damages on roads, which bring many inconveniences and risks to drivers and pedestrians. Therefore, crack repair agents are widely used in municipal engineering;

[0003] When using crack repair agents to repair road cracks, a discharge pipe is usually used to pour the repair agent directly onto the cracks in the road surface. In this way, after the repair is completed, the repaired cracks in the road surface will often bulge due to the accumulation of crack repair agents, which is not conducive to vehicle driving and also affects the appearance of the road.

[0004] In addition, the size of the discharge pipe's opening cannot be changed, resulting in the device being unable to adjust the outflow of the repair agent and the repair width according to the size of the crack. The distance of the discharge pipe from the ground cannot be adjusted at any time. When the discharge pipe is far from the ground, the repair agent flowing out of the discharge pipe cannot completely flow into the crack, causing a waste of the repair agent and affecting the crack repair effect. When the discharge pipe is close to the ground, it is easy to hit the raised part of the road surface and damage the discharge pipe. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a new type of road crack repair machine, which can adjust the outflow speed of the repair agent and the repair width, save the amount of the repair agent, and improve the repair effect and aesthetics.

DETAILED DESCRIPTION

[0026] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0028] Specifically, a discharge pipe 17 is installed at the lower end of the discharge hopper 2, and the storage chamber 1 and the injection chamber 4 are connected to each other through the discharge pipe 17. A throttle valve is installed on the discharge pipe 17, and the flow rate and flow of the repair agent are controlled by the throttle valve, and the flow can be cut off at any time so that the repair agent no longer flows into the injection chamber 4;

[0029] The utility model has an adjustment mechanism installed inside the injection cavity 4, which includes a mounting shell 7 and two nitrogen springs 18. The upper end of the mounting shell 7 is provided with a mounting hole 16, and the mounting hole 16 is slidably matched with the outer wall of the discharge pipe 17. The two nitrogen springs 18 are symmetrically installed on the upper end of the mounting shell 7 along the axis of the mounting hole 16. A connecting ring 19 is detachably installed at the bottom of the discharge hopper 2. The inner diameter of the connecting ring 19 is larger than the outer diameter of the discharge pipe 17. The lower end surface of the connecting ring 19 is fixedly connected to one end of the nitrogen spring 18 away from the mounting shell 7. The connecting ring 19 is arranged at one end of the nitrogen spring 18 and connected to the discharge hopper 2. The entire adjustment mechanism can be disassembled at any time, which is convenient for cleaning the adjustment mechanism.

[0030] Specifically, two rotating shafts 13 are horizontally installed on the inner wall of the mounting shell 7 along the width direction. The two rotating shafts 13 are symmetrical to each other along the symmetry plane of the mounting shell 7. A discharge plate 10 is installed on the rotating shaft 13. Both sides of the discharge plate 10 are against the inner wall of the mounting shell 7. A vertical slide groove 14 is provided on the side away from each other of the two discharge plates 10. The vertical slide groove 14 is located at the upper end of the discharge plate 10. A slider 15 is slidably installed on the vertical slide groove 14. The slider 15 is hinged with a cylinder 12. Two horizontal plates are installed inside the mounting shell 7. 11, the two ends of the horizontal plate 11 are respectively fixed on the inner walls of the two sides where the mounting shell 7 is connected to the rotating shaft 13, the end of the cylinder 12 away from the slider 15 is fixedly mounted on the horizontal plate 11, and the lower ends of the two discharge plates 10 are respectively provided with two closed inclined surfaces 9, and the two closed inclined surfaces 9 can overlap with each other. When the two discharge plates 10 are driven by the cylinder 12 to rotate relatively around the rotating shaft 13 at a certain angle, the closed inclined surfaces 9 on the two discharge plates 10 can overlap with each other, which limits the rotation of the discharge plates 10 and also has a certain interception effect;
