[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Combined with attachment Figure 1-4In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a soil solidifying agent spraying device for roadbed construction, comprising a vehicle plate 1, a transport box 3 is connected to the top of the vehicle plate 1, a feed port 23 and a water pipe 24 are connected to the top of the transport box 3, a first water pump 25 is connected to the water pipe 24, a liquid infusion pipe 26 is connected to one side of the bottom of the transport box 3, one end of the liquid infusion pipe 26 extends to the bottom of the transport box 3, and a second water pump 27 is connected to the liquid infusion pipe 26. A nozzle 28 is connected to the infusion tube 26, and a bracket 29 that cooperates with the nozzle 28 is connected upward on one side of the vehicle plate 1. When not in use, the nozzle 28 can be placed in the bracket 29 and fixed in the inner groove of the bracket 29 by snapping. A rubber hose 5 is connected between the nozzle 28 and the infusion tube 26. A fence 2 is connected to the vehicle plate 1. The fence 2 is used to fix the transport box 3, and on the outside of the transport box 3, the fence 2 also has multiple blank areas for placing curing agent tanks, buckets, etc.

[0026] The transport box 3 carried by the vehicle plate 1 constitutes the main body of the soil solidifier spraying equipment, wherein the vehicle plate 1 is installed or directly set on the supporting bottom plate part of the relevant transport vehicle, which belongs to the scope of the prior art. Since this part of the additional existing structural design is not within the scope of the improvement of the technical solution of this application, and no matter which common method is adopted for the vehicle plate 1, transport vehicle and other parts, it will hardly affect and change the use of the device. Therefore, in this specification and drawings, no excessive details are given. The transport box 3 is a water tank for holding the curing agent solution, which can be fixed on the vehicle plate 1 by integral installation or direct welding. It has a feed port 23 and a water pipe 24 on the top, which are convenient for adding soil curing agent powder and clean water made by curing agent solution into the transport box 3 respectively. The curing agent solution used for soil hardening is sprayed toward the external land through the infusion pipe 26 with the No. 2 water pump 27 when the personnel holds the nozzle 28. This is also one of the general uses of soil curing agent spraying equipment. The area on the vehicle plate 1 is larger than that of conventional equipment. These extra areas can be used to carry a certain amount of curing agent raw materials and water on board, so that during the spraying operation, raw materials and water can be added anytime and anywhere to continuously supply curing agent solution.

[0027] Example 2

[0028] Combined with attachment Figure 1-6The top of the transport box 3 is rotatably connected with a support shaft 10, and the bottom end of the support shaft 10 is connected with a support rod 21. The support rod 21 is rotatably connected downwardly away from one end of the support shaft 10 and is provided with a stirring rod 20. A sprocket chain 18 transmission mechanism is commonly connected between the support shaft 10 and the top of the stirring rod 20. The sprocket chain 18 transmission mechanism includes a sprocket 17 and a sprocket 2 19. The sprocket 17 and the sprocket 2 19 are respectively connected to the support shaft 10 and the stirring rod 20. A chain 18 is commonly connected between the sprocket 17 and the sprocket 2 19. A plurality of blades 22 are connected to the bottom of the stirring rod 20. The top of the transport box 3 is connected with a power mechanism for driving the support shaft 10 to rotate and move in the transport box 3. The power mechanism includes a screw 4, which is located in the top of the transport box 3 and is rotatably connected. A motor 6 that cooperates with the screw 4 is connected to one side of the transport box 3. The screw 4 is connected to a driving block 7 containing a threaded structure, and a limiting mechanism for preventing the driving block 7 from rotating is provided in the top of the transport box 3. The limiting mechanism includes a slide rod 8, and the slide rod 8 is arranged in the top of the transport box 3. One side of the driving block 7 is connected with a sliding sleeve 9 that is slidably connected to the slide rod 8. The sliding rod 8 and the sliding sleeve 9 cooperate with each other to form a limiting mechanism, which provides a limiting condition for the driving block 7 to move as the screw 4 rotates. The support shaft 10 is rotatably connected below the driving block 7, and a worm gear 11 is connected to the support shaft 10. A transmission shaft 12 is connected in the top of the transport box 3, and a No. 2 motor 13 that cooperates with the transmission shaft 12 is connected to one side of the transport box 3. A shaft sleeve 14 containing a slide groove is connected to the transmission shaft 12, and a slider 15 that cooperates with the shaft sleeve 14 is connected to the transmission shaft 12. A worm 16 that cooperates with the worm gear 11 is connected to the shaft sleeve 14.

[0029] When the No. 2 motor 13 is operated, the transmission shaft 12 rotates, and the shaft sleeve 14 on it also rotates together. There is a worm 16 structure on the shaft sleeve 14. After rotation, the support shaft 10 is rotated by cooperating with the worm gear 11 on the support shaft 10. The transport box 3 is generally not a regular cylindrical shape. The present application adopts a rectangular container with smaller shape constraints. This type of container is often used in most equipment and is representative. The support shaft 10 is located on the center line of the rectangular container. A stirring rod 20 is arranged parallel to the bottom of the support shaft 10. The stirring rod 20 carries a plurality of blades 22, which stir the solution in the transport box 3 by rotation, so that the newly added curing agent powder is dissolved in the water. It is connected to the support shaft 10 through a support rod 21 and is respectively connected to the two ends of the support rod 21. The difference is that the support shaft 10 and the support rod 21 are fixed, while the stirring rod 20 can be moved at one end of the support rod 21. In addition, a set of sprocket chain 18 transmission mechanisms are connected between the stirring rod 20 and the support shaft 10. Through this mechanism, the stirring rod 20 realizes synchronous rotation with the support shaft 10, which enables the stirring rod 20 to rotate around the support shaft 10 through the extension and connection of the support rod 21, and also rotates at the same time, which complicates the rotation state, is conducive to the full stirring of the solution, and is conducive to the rapid fusion of the newly added curing agent powder and water, and provides materials for spraying curing agent on the soil in real time. In addition, in order to cope with the stirring path with a perfect circle as the trajectory in the rectangular container, it is not easy to make the materials between the various areas in the container fully dissolved, and there are easy to be mixing dead corners. Therefore, through the rotation of the screw 4 and the subsequent movement of the drive block 7, the stirring module is moved back and forth along its center line in the transport box 3, thereby expanding the stirring area and improving the stirring effect. This back and forth state needs to be achieved by using a forward and reverse motor as the No. 1 motor 6.

[0030] During the specific implementation of the present invention, when the device is used to harden the road surface with a soil curing agent solution, the soil curing agent is poured into the transport box 3 through the feed port 23, and an appropriate amount of water is added thereto through the water pipe 24. Under normal circumstances, the material-water ratio is about 1 to 9. The No. 1 motor 6 and the No. 2 motor 13 are operated simultaneously, respectively rotating the screw 4 and the transmission shaft 12. The rotation of the screw 4 causes the stirring mechanism to move in the transport box 3 and enter into various areas to stir the materials. The rotation of the transmission shaft 12 will cause the stirring mechanism to move in the transport box 3 through the worm gear 11 and the worm 16. The transmission system makes the components in the stirring mechanism rotate, and through a special stirring method, the curing agent and water are allowed to merge with each other and accelerate the effect. The mixed solution is output and sprayed on the outside land through a person holding a nozzle 28 on one side of the transport box 3. It penetrates into the soil and undergoes relevant physical and chemical reactions to harden the sparse soil. During the spraying operation, the solution in the transport box 3 naturally decreases. During this period, the soil curing agent solution can be quickly replenished by continuing to add curing agent powder and an appropriate amount of water to the transport box 3 and stirring.

[0031] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
