A spraying device is installed at the rear end of the frame 1 in the direction of travel, and the spraying device includes a vertical spraying component 7 and a horizontal spraying component 8, and the vertical spraying component 7 and the horizontal spraying component 8 are respectively connected to the infusion pump 10 through a second infusion tube 102 and a third infusion tube 103. The repair agent can be sprayed on the soil by the spraying device through the infusion pump 5 to repair the soil.

[0036] Specific:

[0037] Reference Figure 1 and Figure 2 As shown, the vertical spraying assembly 7 is composed of a first liquid storage pipe 71, a first liquid outlet pipe 72 and a first nozzle 73. The first liquid storage pipe 71 is installed at the rear end of the frame 1. The first liquid storage pipe 71 is connected to the second liquid infusion pipe 102. A plurality of first liquid outlet pipes 72 are distributed on the first liquid storage pipe 71, and the first liquid outlet pipes 72 are horizontally arranged. A plurality of first nozzles 73 are connected below each of the first liquid outlet pipes 72. The repair agent is transported to the first liquid storage pipe 71 by the infusion pump 10, and then the first nozzle 73 sprays the shallow soil surface vertically downward.

[0038] Reference Figures 3 to 6 As shown, the lateral spraying assembly 8 is composed of a second liquid storage pipe 81, a second liquid outlet pipe 82 and a second nozzle 83. The second liquid storage pipe 81 is installed below the rear end of the frame 1 through a telescopic frame 6. The height of the lateral spraying assembly 8 is adjusted by adjusting the height of the second nozzle 83 through the telescopic frame 6, so that soils of different depths can be sprayed horizontally; the second liquid storage pipe 81 is connected to the third liquid infusion pipe 103, and a plurality of second liquid outlet pipes 82 connected to the second liquid storage pipe 81 are vertically and evenly distributed below the second liquid storage pipe 81, and the liquid outlets of the second liquid outlet pipes 82 are all installed with second nozzles 83, as shown in FIG. Figure 4 As shown, the main body of the second nozzle 83 is cylindrical, with an open upper end and a closed lower end. A V-shaped baffle 832 is welded on the outer wall of the second nozzle 83 through a reinforcing rib 8321. The V-shaped baffle 832 can block part of the side wall of the second nozzle 83. When the second nozzle 83 is installed, the V-shaped baffle 832 is always in front of the moving direction of the second nozzle 83. When the device is working, the baffle 832 can push away the soil in front of the second nozzle 83, which makes it convenient for the second nozzle 83 to spray the repair agent while preventing the soil from blocking the nozzle of the second nozzle 83; a plurality of spray holes 831 are evenly opened on the side wall of the second nozzle 83 not blocked by the baffle 832, and a nozzle 9 is installed in each spray hole 831.

[0039] In the present embodiment, the nozzle 9 is composed of a nozzle barrel 91, a fixing ring 92, a filter screen 93, a positioning ring 94, a spring 95, a support rod 96 and a stopper 97, wherein the outer annular surface of the nozzle barrel 91 has the same contour as the inner annular surface of the spray hole 831, the end of the nozzle barrel 91 with a larger diameter faces inward, the end of the nozzle barrel 91 with a smaller diameter faces outward, and the length of the nozzle barrel 91 is greater than the length of the spray hole 831. When installed in the spray hole 831 of the nozzle barrel 91, the excess part of the end with a smaller diameter of the nozzle barrel 91 protrudes and is connected with a fixing ring 92, and the fixing ring 92 is located on the outside of the spray hole 831. Because the outer diameter of the fixing ring 92 is greater than the diameter of the outer end of the spray hole 831, the nozzle barrel 91 can be fixed in the spray hole 831; on the inner wall of the nozzle barrel 91 close to the inner end It is covered with a filter screen 93, and a positioning ring 94 is fixedly installed on the inner wall of the nozzle barrel 91 near the filter screen 93. The positioning ring 94 is provided with two mounting grooves 941 with openings facing outwards. A support rod 96 is fixedly connected in the mounting groove 941 through a spring 95. The ends of the two support rods 96 away from the spring 95 are fixedly connected to a block 97, wherein the block 97 is hemispherical, and the side on which the block 97 is connected to the support rod 96 is arc-shaped, and the diameter of the block 97 is roughly the same as the diameter of the outer end of the spray hole 831. When the block 97 slides outward under pressure, the block 97 can gradually push out the soil blocking the nozzle opening until the block 97 completely slides out of the nozzle opening, which not only cleans the nozzle, but also controls the position of the block 97 by controlling the water flow pressure, thereby controlling the amount of repair agent sprayed.

[0040] The utility model discloses a repair agent spraying device for improving saline-alkali soil. When working, various raw materials of the repair agent are first put into a liquid storage tank 5, and then the stirring device 51 is started to mix the raw materials evenly. Then, the soil turning component is started through the control console 4 to turn and loosen the saline-alkali soil. Then, the spraying device is supplied with liquid through the infusion pump 10, and the repair agent is sprayed on the shallow soil by the vertical spraying component 7. Then, the height of the second nozzle 83 of the horizontal spraying component 8 is adjusted at any time through the telescopic frame 6, and the repair agent is sprayed on different deep soils horizontally. The deep soil can be sprayed by the device, so that the repair agent and the soil are mixed evenly to improve the repair effect.

[0041] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
