[0034] like Figures 1 to 9 As shown, a crack grouting repair machine for construction engineering comprises a transport vehicle 1, a stirring tank 2 is arranged on the upper part of the transport vehicle 1, a heater 3 is arranged on the side of the stirring tank 2, a motor 4 is arranged on the top of the stirring tank 2, a stirring rod 5 is fixedly connected to the driving end of the motor 4, a humidifying assembly is arranged on the upper part of the stirring tank 2, a perfusion pipe 7 is arranged and fixedly connected to the lower part of the side of the stirring tank 2, a clutch assembly is arranged inside the perfusion pipe 7, a mixing assembly is arranged inside the stirring tank 2, a heating rod of the heater 3 extends into the interior of the stirring tank 2, the humidifying assembly acts on the interior of the stirring tank 2, a support rod 10 is arranged at the end of the transport vehicle 1, the clutch assembly is movably connected to the support rod 10, three groups of the mixing assembly are issued in a ring matrix with the stirring rod 5 as the center, and the mixing assembly and the humidifying assembly are used in conjunction with each other;

[0035] In the sophisticated process of pouring and repairing cracks in the road surface, the repair material is placed in the mixing tank 2, and the motor 4 drives the stirring rod 5 to rotate and stir the material. To ensure the stirring effect, the mixing component plays a key role. It can effectively break the centrifugal force during the stirring process, and promote the material to flow smoothly in the mixing tank 2, thereby greatly improving the uniformity of heating. At the same time, with the cooperation of the humidification component, the mixing tank 2 can be indirectly humidified while stirring and heating, ensuring the viscosity of the material and avoiding drying due to dehydration. The carefully modulated repair material flows smoothly through the perfusion pipe 7 and is accurately poured into the cracks. The clutch component can be used to control the circulation of the perfusion pipe 7, so that the perfusion no longer requires the drive of the pump, and the motor 4 is used as the driving force to reduce energy consumption.

[0036] like Figures 2 to 5As shown, the humidification assembly includes a water storage tank 601 arranged on the upper part of the stirring tank 2, the bottom end of the water storage tank 601 is fixedly connected to a discharge pipe 602, a driving wheel 603 is fixedly sleeved on the upper part of the outer surface of the stirring rod 5, an extension plate 604 is fixedly connected to the inner wall of the stirring tank 2, a gear 1 605 is rotatably connected to the upper surface of the extension plate 604, a gear 2 606 is arranged on the side of the gear 1 605, a valve stem 610 is movably inserted into the inner wall of the bottom end of the discharge pipe 602, and the driving wheel 603 and the gear 1 60 5 meshes, gear 1 605 meshes with gear 2 606, a shift block 607 is fixedly connected to the upper surface of gear 1 605 and gear 2 606, a slide bar 608 is slidably connected to the upper surface of the extension plate 604, the slide bar 608 is movably connected to the outside of the shift block 607, a push rod 609 is hinged on the upper surface of the slide bar 608, one end of the push rod 609 away from the slide bar 608 is hinged to the bottom end of the valve stem 610, a through hole 611 is opened inside the valve stem 610, and the through hole 611 is set in an I-shape;

[0037] The motor 4 drives the stirring rod 5 to rotate to achieve the stirring effect. Under the precise drive of the driving wheel 603, the gear 1 605 and the gear 2 606 can rotate synchronously and in opposite directions. During the rotation of the two, the gear shifter will rotate around the center of the corresponding gear, and then the slide bar 608 will be driven to make a linear reciprocating motion. The push rod 609 connected to the slide bar 608 moves accordingly, flexibly pulling or pushing the valve stem 610 to achieve the effect of driving the valve stem 610 to reciprocate up and down, and then the clean water flowing into the through hole 611 can flow into the stirring tank 2, achieving the effect of stage humidification, thereby ensuring that the material is at a suitable humidity and viscosity to avoid drying due to dehydration.

[0038] like Figure 3 , Figure 8 and Fig. 9 As shown, the clutch assembly includes a positioning rod 801 movably inserted in the side of the mixing tank 2, a spiral rod 802 movably inserted in the middle of the positioning rod 801, the spiral rod 802 extends into the interior of the perfusion pipe 7, and one end of the spiral rod 802 extending into the mixing tank 2 is fixedly connected with a side bevel gear 803, and a bottom bevel gear 804 is fixedly sleeved at the lower part of the outer surface of the mixing rod 5, and the bottom bevel gear 804 is meshed and connected with the side bevel gear 803. A support 805 is fixedly connected to the lower part of the side of the mixing tank 2, and a seesaw 806 is movably connected to the middle of the support 805. The bottom end of the seesaw 806 is movably connected to the positioning rod 801, and a spring 807 is provided on the upper side of the seesaw 806. A rope 808 is fixedly connected to the top of the seesaw 806, and a cam 809 is movably sleeved in the middle of the handrail 10. A fixed pulley 810 is provided on the edge of the upper surface of the transport vehicle 1, and the rope 808 passes through the fixed pulley 810 and is fixedly connected to the outer surface of the cam 809.

[0039] The rotating cam 809 pulls the rope 808 to wrap around the outer surface of the cam 809. Under the limit of the fixed pulley 810, the rope 808 pulls the upper part of the seesaw 806 to drive the seesaw 806 to rotate around the support 805. The upper part of the seesaw 806 is away from the mixing tank 2 and pulls the spring 807. The lower part of the seesaw 806 is close to the mixing tank 2 and pushes the positioning rod 801 to slide into the inside of the mixing tank 2, thereby driving the side bevel gear 803 to move and mesh with the bottom bevel gear 804. Under the unified drive of the motor 4, the side bevel gear 803 drives the screw rod 802 to rotate. The screw rod 802 rotates in the perfusion pipe 7 to continuously push the repair material in the mixing tank 2 into the perfusion pipe 7, and pressurizes and pushes it out from the bottom, so that the material is accurately filled in the crack. This design not only realizes the unified drive of the motor 4, without the need to use an additional pump to drive the flow perfusion of the material, thereby greatly reducing energy consumption, but also can be accurately controlled according to the actual width and depth of the crack, effectively reducing material waste.

[0040] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the mixing assembly includes a central rod 901 rotatably connected to the inside of the mixing tank 2, a slave gear 902 is fixedly sleeved on the upper outer surface of the central rod 901, an upper bevel gear 903 is fixedly sleeved on the middle outer surface of the mixing rod 5, and the upper bevel gear 903 is meshedly connected with the slave gear 902, a transmission rod 904 is movably inserted through the outer surface of the central rod 901, and transmission wheels 905 are fixedly connected at both ends of the transmission rod 904, and the transmission wheel 905 is meshedly connected with the upper bevel gear 903, and an eccentric wheel 905 is fixedly sleeved in the middle of the transmission rod 904. 06, the outer surface of the eccentric wheel 906 is movably connected with a holder 910, the transmission rod 904 and the eccentric wheel 906 are symmetrically arranged in the middle of the center rod 901, and the upper and lower eccentric wheels 906 are arranged in the same position, the end of the holder 910 is fixedly connected with a threaded rod 909, the outer surface of the center rod 901 is fixedly connected with a bracket 907, the middle of the bracket 907 is movably inserted with a threaded barrel 908, the threaded barrel 908 is threadedly connected to the outer surface of the threaded rod 909, and the outer surface of the threaded barrel 908 is fixedly connected with a stirring blade 911;

[0041] While the mixing rod rotates and stirs, the driving wheel 603 will synchronously drive the slave gear 902 to rotate, and then drive the center rod 901 to rotate. During the rotation, the transmission wheel 905 will indirectly mesh with the upper bevel gear 903, and then drive the eccentric wheel 906 to rotate under the action of the transmission rod 904. The movable clamping connection between the holder 910 and the eccentric wheel 906 can make the eccentric wheel 906 pull the holder 910 to move up and down, and then drive the threaded rod 909 to reciprocate up and down, and further drive the threaded barrel 908 to rotate forward and reverse in a short time. The forward and reverse rotation of the stirring blade 911 can avoid the influence of centrifugal force, and can make the material mixing and flowing in the stirring tank 2 more uniform, ensuring that the material is heated uniformly in the stirring tank 2 and the viscosity is uniform from top to bottom, avoiding stratification.

[0042] The technical solution provided by the present invention is to stir and heat the repair material delivered to the stirring tank 2 in real time through the stirring tank 2, the motor 4, the stirring rod 5 and the heater 3. The specific structure and connection method of the repairing and pouring machine are the existing technologies well known to the staff in this field, and will not be elaborated on here. The motor 4 is started to drive the stirring rod 5 to rotate to achieve the stirring effect. Under the drive of the driving wheel 603, the gear 1 605 and the gear 2 606 can be driven to rotate synchronously in the opposite direction. During the rotation of the two, the speed dial will be driven to rotate around the center of the corresponding gear. Since the speed dial is connected to the The inside of the slide bar 608 will drive the slide bar 608 to make a linear reciprocating motion. During the movement of the slide bar 608, the pull rod is driven, and the push rod 609 pulls or pushes the valve stem 610 to move, so as to achieve the effect of driving the valve stem 610 to reciprocate up and down, so that the clean water flowing into the through hole 611 can flow into the mixing tank 2, achieving the effect of stage humidification, thereby ensuring that the material is at a suitable humidity and viscosity, avoiding the situation of drying due to dehydration. When the stirring rod 5 rotates and stirs, the driving wheel 603 will synchronously drive the gear 902 to rotate, thereby driving the center rod 9 01 rotates, the stirring blade 911 rotates around the central rod 901 to achieve the stirring effect, breaking the centrifugal force generated by the rotation of the stirring rod 5. In addition, the transmission wheel 905 will indirectly mesh with the upper bevel gear 903 during the rotation process, and then drive the eccentric wheel 906 to rotate under the action of the transmission rod 904. The trajectory of the eccentric wheel 906 rotating around the transmission rod 904 is an arc. The movable connection between the holder 910 and the eccentric wheel 906 can make the eccentric wheel 906 pull the holder 910 to move up and down, thereby driving the threaded rod 909 to reciprocate up and down, and the threaded cylinder 908 is supported by the bracket. 907 is limited, and the threaded rod 909 will drive the threaded barrel 908 to rotate inside the bracket 907 during the up and down movement. Since the threaded rod 909 reciprocates up and down, the threaded barrel 908 will rotate forwards and backwards in a short time. The stirring blade 911 achieves a stirring effect as the threaded barrel 908 rotates. The forward and reverse rotation of the stirring blade 911 can avoid the influence of centrifugal force, so that the materials in the stirring tank 2 can be mixed and flowed more evenly, ensuring that the materials are heated evenly in the stirring tank 2 and the viscosity is evenly distributed up and down, avoiding stratification.

[0043] When pushing the transport vehicle 1 to the road section that needs to be repaired, align the bottom of the perfusion pipe 7 with the crack, rotate the cam 809 to pull the rope 808 to wrap around the outer surface of the cam 809, and under the limit of the fixed pulley 810, the purpose of pulling the rope 808 can be achieved. The rope 808 pulls the upper part of the seesaw 806 to drive the seesaw 806 to rotate around the support 805. The upper part of the seesaw 806 moves away from the mixing tank 2 and pulls the spring 807. The lower part of the seesaw 806 approaches the mixing tank 2 and pushes the positioning rod 801 to slide toward the inside of the mixing tank 2, thereby driving the side bevel gear 803 to move and engage with the bottom bevel gear 804. The stirring rod 5 drives the bottom bevel gear 804 to rotate and then drives the side bevel gear The wheel 803 rotates, and the side bevel gear 803 drives the screw rod 802 to rotate. The screw rod 802 rotates in the perfusion pipe 7 to push the repair material in the mixing tank 2 into the perfusion pipe 7 and push it out from the bottom with pressure, so that the material fills the crack. The motor 4 is used as a unified driving force, and there is no need to use a pump separately to drive the flow perfusion of the material, which reduces energy consumption. After the cam 809 is rotated in the opposite direction, the spring 807 retracts to pull the rocker 806 to reset, so that the side bevel gear 803 is separated from the bottom bevel gear 804, thereby achieving the control of the opening and closing of the material flow perfusion. Effective control can be achieved according to the actual situation of the crack, reducing material waste.
