[0037] refer to Figure 19 to Figure 22A swing seat slot 411 is provided on the side of the swing seat 410, a swing seat bearing seat 412 is provided on one side of the swing seat slot 411, a swing seat shaft 413 is provided on the rear side of the swing seat 410, the swing seat shaft 413 is rotatably connected to the No. 3 hole 315 on one side of the jack seat 310, a swing slider 420 is slidably connected in the swing seat slot 411, a swing slider screw hole 421 on the side of the swing slider 420 is threadedly connected to the No. 2 screw 440, the No. 2 screw 440 is rotatably connected to the swing seat shaft 413, a swing slider pin 422 on the upper part of the swing slider 420 is rotatably connected to the middle slider hole 431 in the middle of the middle slider 430, and the middle slider 430 is slidably connected to the swing rod slot 331 on the side of the swing rod 330.

[0038] refer to Fig.10 The outer side of the swing seat shaft 413 is fixedly connected to a pulley, and the pulley is connected to the first pulley 395 through a belt.

[0039] refer to Figure 16 to Figure 17 The lower part of the lifting rod 350 is provided with a plug 360, the screw 351 at the lower part of the lifting rod 350 is threadedly connected to the air inlet 361 in the middle of the plug 360, a group of air outlet holes 362 are evenly distributed on the cylindrical surface of the plug 360, and a cone head 363 is provided at the lower part of the plug 360. When the lifting rod 350 moves up and down, the depth of the plug 360 inserted into the soil changes. The plug 360 and the lifting rod 350 are threadedly connected, and the plug 360 is rotated so that the plug 360 can be completely inserted into the soil, ensuring that the air outlet holes 362 on the plug 360 can be bought into the soil to prevent air leakage.

[0040] refer to Fig.16 , Fig.18 A front slide groove 318 is provided on the front side of the jack seat 310, and a front seat bearing seat 319 is provided on the upper part of the front slide groove 318. The front seat bearing seat 319 is rotatably connected with a No. 1 screw rod 380, and the No. 1 screw rod 380 is threadedly connected with a No. 2 slider screw hole 371 in the middle of the No. 2 slider 370, and the No. 2 slider screw hole 371 is slidably connected with the front slide groove 318, and the upper part of the No. 2 slider 370 is connected with a sensing switch, and a sensing block 353 is provided on the side of the lifting rod 350. When the lifting rod 350 moves up and down, the sensing block 353 triggers the sensing switch.

[0041] The lifting rod hole 354 on the upper part of the lifting rod 350 is connected to the compressed air tank 113 on the rear side of the frame 110 through an air pipe. When the motor 140 rotates, it drives the spline shaft 130 to rotate, and the rotation of the spline shaft 130 drives a group of first pulleys 395 to rotate. Each first pulley 395 rotates and drives the socket seat 310 to rotate through the belt. The swing seat 410 rotates to drive the swing rod 330 to swing. The swing rod 330 swings and the power rod 390 swings. When the power rod 390 swings, the first slider 340 slides along the socket seat 310. The power rod 390 drives the lifting rod 350 to slide back and forth up and down along the socket seat 310. The lifting rod 350 drives the plug 360 to move back and forth up and down. When the plug 360 moves downward, the plug 360 is inserted into the soil. After the plug 360 is inserted into the soil to a certain depth, the induction block 3 53 triggers the induction switch, and the compressed air in the compressed air tank 113 is injected into the soil. The No. 2 screw rod 440 is rotated to drive the middle slider 430 to move up and down. The up and down movement of the middle slider 430 will change the swing angle of the rocker arm 330. The swing angle of the rocker arm 330 changes, which causes the swing angle of the power rod 390 to change. The swing angle of the power rod 390 changes greatly, the reciprocating distance of the lifting rod 350 changes, and the depth of the plug 360 inserted into the soil changes. The depth of air injection is adjusted, and the No. 1 screw rod 380 can be rotated to adjust the position of the No. 2 slider 370 and the induction switch, so that the compressed air is injected into the soil when the plug 360 is fully inserted into the soil.

[0042] A method for operating a soil improvement device comprises the following steps: when using the device, in the first step, a motor vehicle pulls the soil improvement device, starts the motor 140, and when the motor 140 rotates, it drives the spline shaft 130 to rotate, and the rotation of the spline shaft 130 drives a group of first pulleys 395 to rotate, and each first pulley 395 rotates through a belt to drive the socket seat 310 to rotate, and the swing seat 410 rotates to drive the swing rod 330 to swing, and the swing rod 330 swings and the power rod 390 swings, and when the power rod 390 swings, the first slider 340 slides along the socket seat 310, and the power rod 390 drives the lifting rod 350 to slide along the socket seat 310. The lifting rod 350 reciprocates up and down, and the plug 360 moves up and down. When the plug 360 moves downward, the plug 360 is inserted into the soil. In the second step, after the plug 360 is inserted into the soil to a certain depth, the induction block 353 triggers the induction switch, and the compressed air in the compressed air tank 113 is injected into the soil to form soil aeration. The second screw rod 440 is rotated to drive the middle slider 430 to move up and down. The up and down movement of the middle slider 430 will change the swing angle of the swing rod 330. The swing angle of the swing rod 330 changes, which makes the swing angle of the power rod 390 change. The swing angle of the power rod 390 changes, and the lifting rod 350 is lifted. The reciprocating distance of the lowering rod 350 changes, the depth of the plug 360 inserted into the soil changes, and the depth of air injection is adjusted. The position of the second slider 370 and the induction switch can be adjusted by rotating the No. 1 screw rod 380, so that when the plug 360 is fully inserted into the soil, the compressed air is injected into the soil. The rotating pitch shaft 220 drives a group of pitch blocks 230 to move synchronously with the same distance. A group of pitch blocks 230 respectively drives their respective jack devices 300 to move synchronously with the same distance, so that the density of the injected air changes to adapt to the requirements of injecting air in different soils. When the jack device 300 is inserted into the soil, the jack device 3 00 is fixed by the soil. If the device moves forward mechanically, tension is generated between the jack device 300 and the body 100. If the jack device 300 and the floating frame 120 are fixed, the jack device 300 is easily damaged. The frame 110 and the floating frame 120 are connected by a spring 150, so that when the jack device 300 is inserted into the soil, the floating frame 120 can slide relative to the frame 110, so that the device can complete the jacking and air injection actions without stopping, thereby improving work efficiency. If the soil hardness is high, the jacking and air injection actions can be completed when the frame 110 is stopped.

[0043] Rotating the No. 2 screw rod 440 drives the middle slider 430 to move up and down. The up and down movement of the middle slider 430 will change the swing angle of the swing rod 330. The change in the swing angle of the swing rod 330 causes the swing angle of the power rod 390 to change. The change in the swing angle of the power rod 390 changes the reciprocating distance of the lifting rod 350, and the depth of the plug 360 inserted into the soil changes. The depth of air injection can be adjusted. The variable pitch device 200 can change the distance between the jack devices 300, so that the density of the injected air changes. Soil aeration adapts to the density requirements of air injected into different soils. The frame 110 and the floating frame 120 are connected by a spring, so that when the jack device 300 is inserted into the soil, the floating frame 120 can slide relative to the frame 110, so that the device can complete the jacking and air injection actions without stopping. Soil aeration improves work efficiency and avoids damage to the jack device 300. If the soil hardness is high, the jacking and air injection actions can be completed when the frame 110 is stopped.
