Figure 1-Figure 7 and Fig.11 As shown, the following preferred technical solutions are provided: A road construction crack treatment device comprises a cart 1 and a stirring and heating barrel 2 fixedly mounted on the cart 1, the stirring and heating barrel 2 being used to heat and stir crack filling materials to keep them in a liquid state and in a uniformly mixed state, a pump 3 being fixedly mounted at the front end of the cart 1, the pump 3 being used to extract crack filling materials from the stirring and heating barrel 2 to fill the cracks, the input end of the pump 3 being connected to the stirring and heating barrel 2 through a connecting pipe 4, the output end of the pump 3 being sealed and connected to a multi-directional telescopic pipe 6, the other end of the multi-directional telescopic pipe 6 being sealed and fixedly connected to an outer shell 5, and a movable nozzle 7 being installed in an inner cavity at one end of the lower end of the outer shell 5, and a movable nozzle 7 being installed in an inner cavity at one end of the outer shell 5. A discharge assembly 8 is provided at the end, and the discharge assembly 8 is used for discharging the residual crack filling material in the outer shell 5 to prevent the crack filling material from solidifying in the outer shell 5. A clamping frame 9 is slidably installed at one end of the top surface of the outer shell 5, and a lifting assembly 10 is fixedly installed at the top of the front end of the cart 1.

[0025] The nozzle 73 includes a sealing ring 731 and a third through hole 732 arranged on the sealing ring 731. The sealing ring 731 is sealingly slidably arranged in the annular inner groove 723. The nozzle body 733 is sealingly fixedly installed on the bottom surface of the sealing ring 731, and the nozzle body 733 is sealingly fixedly installed at the lower end opening of the third through hole 732.

[0026] The guiding mechanism 74 includes a connecting plate 741 and a connecting shaft 742 fixedly installed in the middle of the top surface of the connecting plate 741, and the connecting shaft 742 is set in the bottom rotating groove 721 through a ball rotation, and the nozzle body 733 passes through and is fixedly installed at one end of the connecting plate 741, and a pair of long rollers 743 are rotatably arranged side by side on the bottom surface of the other end of the connecting plate 741, and the bottom surface of the long rollers 743 is set lower than the bottom surface of the nozzle body 733, thereby ensuring that when the bottom surface of the nozzle body 733 is set at the opening of the road crack, the lower end of the long roller 743 can be inserted into the road crack.

[0027] Specifically, after the cracks in the road have been grooved, the staff can push the cart 1 to the cracks in the road, and after aligning the long rollers 743 with the initial ends of the cracks in the road, the lifting assembly 10 can be started to drive the multi-directional telescopic pipe 6 to extend and retract up and down, and the multi-directional telescopic pipe 6 will drive the outer shell 5 to move downward, so that the long rollers 743 are respectively inserted into the cracks in the road, and the nozzle body 733 will also move downward to the opening of the cracks in the road. Then the staff pushes the cart 1 forward in a straight line, and the horizontal slide 71 can slide left and right in the bottom groove 51, and the guiding mechanism 74 is arranged on the convex groove 51. The rotation setting at the bottom of the block 72 and the nozzle body 733 can be rotated along the center of the connecting shaft 742, so that the pair of long rollers 743 can roll in the curved road cracks or along the track of the road cracks, thereby ensuring that the nozzle body 733 is constantly located directly above the crack opening and can spray crack filling materials to repair the road cracks. The staff does not need to repair the cracks little by little along the track of the cracks. The operation is convenient and fast, and the practicability is strong. It not only improves the efficiency of repairing road cracks, but also saves manpower and improves the user experience of the device. Furthermore, by providing the transverse slide plate 71 and the sealing ring 731, not only the movable effect of the nozzle body 733 is ensured, but also the connectivity and sealing of the nozzle body 733 during the movement are ensured.

[0028] In order to solve the technical problem of how to facilitate the staff to move the device, such as Figure 1-Figure 4 As shown, the following preferred technical solutions are provided: The movable nozzle 7 includes a transverse slide 71 and a protrusion 72 fixedly installed at the middle of the bottom surface of the transverse slide 71, and the bottom surface of the protrusion 72 is rotatably provided with a guiding mechanism 74 and a nozzle 73, and the guiding mechanism 74 is used to align the nozzle 73 with the road crack.

Through the arrangement of the multi-directional telescopic pipe 6, the up and down and left and right movements of the outer shell 5 can be realized while ensuring the connectivity.

[0030] The lifting assembly 10 includes an electric push rod 101 and a circular collar 102 fixedly mounted on the output end of the electric push rod 101. The electric push rod 101 is fixedly mounted on the trolley 1. The circular collar 102 is fixedly sleeved on the outer peripheral wall of the L-shaped thick tube 62. A transverse telescopic rod 103 is fixedly mounted on the outer peripheral wall of the output end of the electric push rod 101, and the other end of the transverse telescopic rod 103 is fixedly mounted on the L-shaped piston tube 63. By setting the transverse telescopic rod 103, the overall stability of the multi-directional telescopic pipe 6 is improved without affecting the extension and retraction of the multi-directional telescopic pipe 6.

[0031] Specifically, by setting up an electric push rod 101, when the device is not used for grouting, the electric push rod 101 can be started, so that the output end of the electric push rod 101 drives the multi-directional telescopic pipe 6 to move upward as a whole, and the multi-directional telescopic pipe 6 can drive the outer shell 5 to move upward as a whole, so that the movable nozzle 7 will not touch the ground, making it convenient for the staff to move the device as a whole.

[0032] In order to solve the technical problem of how to clean the crack filling material remaining inside the outer shell 5 after the device is used, Figure 4-Figure 9 As shown, the following preferred technical solutions are provided: The discharge assembly 8 includes a pressing plate 81 and a one-way valve 82 fixedly installed through the middle of the pressing plate 81. The pressing plate 81 is sealingly and slidably arranged in the inner chamber 52, and special-shaped frames 83 are fixedly installed at both ends of the top surface of the pressing plate 81. A slot 831 is opened on the surface of one end of the upper end of the special-shaped frame 83, and the special-shaped frames 83 are respectively slidably arranged in the top square hole 55. A roller 84 is rotatably installed on the outer wall of the lower end of the special-shaped frame 83, and the special-shaped frame 83 is elastically slidably installed on the top of the outer shell 5 through the connecting spring 85. When the device performs the highway grouting operation, the roller 84 will contact the bottom surface, so that the pressing plate 81 is driven to the top of the inner cavity of the inner chamber 52.

[0033] The card-jointing frame 9 includes a transverse plate 91 and embedded sliders 92 respectively fixedly installed on both sides of the bottom surface of the transverse plate 91, and the embedded sliders 92 are respectively set in the top slide grooves 56 by ball sliding, and the embedded sliders 92 are made of magnetic metal material, and the position of the card-joining frame 9 can be fixed by cooperating with the magnetic block 57. L-shaped plug rods 93 are respectively fixedly installed at both ends of the top surface of the transverse plate 91.

[0034] Specifically, when the staff uses the device to perform crack filling operation on the road, the outer shell 5 will drive the discharge assembly 8 to move downward together. When the roller 84 contacts the ground, the outer shell 5 will continue to move downward relative to the discharge assembly 8. At this time, the pressing plate 81 will move upward in the inner chamber 52 until it moves to the top of the inner chamber 52. At this time, the outer shell 5 will move downward to a suitable position. When repairing the cracks in the road, the crack filling material can enter the inner chamber 52 through the one-way valve 82, and finally the material is sprayed out through the nozzle body 733. Filling. When the repair is completed, the crack filling materials in each pipeline are all sprayed out from the nozzle body 733 by air pressure, and then the outer shell 5 is driven to move upward by the lifting component 10. During this process, the outer shell 5 will move upward relative to the discharge component 8. Under the elastic force of the connecting spring 85, the pressing plate 81 will press out the crack filling materials in the inner chamber 52 to prevent the crack filling materials from accumulating and solidifying in the inner chamber 52. The up and down movement process of the outer shell 5 is cleverly utilized, which is fully automatic, saves manpower, and prevents blockage in the outer shell 5; Furthermore, when the staff is repairing cracks on an uneven road surface, the discharge assembly 8 can be pulled upward to the extreme position as a whole, and the clamping frame 9 can be pushed in the direction of the discharge assembly 8 so that the front end of the L-shaped rod 93 is inserted into the slot 831, thereby fixing the discharge assembly 8 as a whole. When the road repair is completed, the clamping frame 9 is pushed backward to separate the L-shaped rod 93 from the slot 831. Under the elastic force of the connecting spring 85, the pressing plate 81 will press out the crack filling material in the inner chamber 52 to prevent the crack filling material from accumulating and solidifying in the inner chamber 52, thereby improving the adaptability of the device.
