When the driving rod and the gear rod are in contact, the driving rod drives the rotating rod to rotate. A lower bearing seat is provided at the lower part of the fertilizer water outlet, the lower bearing seat is hinged to the No. 1 shaft on one side of the No. 2 connecting rod, the rotating rod and the No. 2 connecting rod are connected through the No. 1 connecting rod, the three holes on one side of the No. 1 connecting rod are hinged to the No. 2 shaft on the other side of the No. 2 connecting rod, and the two holes in the middle of the No. 1 connecting rod are hinged to the rotating rod shaft on one side of the rotating rod.

[0005] The lower part of the injection seat is provided with two upper and lower guide holes, the injection tube is slidably connected to the guide holes, the retaining ring in the middle of the injection tube is arranged in the middle of the two guide holes, the rotating rod and the injection tube are connected through the No. 4 connecting rod, one side of the No. 4 connecting rod is hinged to the rotating rod shaft on one side of the rotating rod, and the other side of the No. 4 connecting rod is hinged to the injection tube dumpling shaft on the upper part of the injection tube.

The intermediate shaft of the worm 430 is connected to the output shaft of the motor 440, and the motor 440 is fixed to the side of the upper bearing seat 311.

[0022] refer to Figure 8 to Figure 9 A shift rod 333 is provided on the side of the rotating rod 330. When the driving rod 320 and the shift rod 333 are in contact, the driving rod 320 drives the rotating rod 330 to rotate.

[0023] The rotation of the motor 440 drives the worm 430 to rotate, the rotation of the worm 430 drives the turbine 420 to rotate, the rotation of the turbine 420 drives the driving rod 320 to rotate, when the driving rod 320 rotates, the driving rod 320 drives the rotating rod 330 to rotate through the gear lever 333 on the side of the rotating rod 330, the worm 430 and the motor 440 have a large transmission ratio and a self-locking effect, because each time the device applies fertilizer, the rotating rod 330 rotates one circle, and fertilizes once, the device needs to be moved to the next position for fertilization, the large transmission ratio of the worm 430 and the turbine 420 can conveniently control the driving rod 320 to rotate only one circle each time, and the self-locking effect of the worm 430 and the turbine 420 can ensure that when the device moves, the position of the piston 360 and the injection tube 370 will not malfunction.

[0024] refer to Figures 5 to 11 A lower bearing seat 313 is provided at the lower part of the fertilizer water outlet 211, and the lower bearing seat 313 is hinged to the first shaft 351 on one side of the second connecting rod 350. The rotating rod 330 and the second connecting rod 350 are connected through the first connecting rod 340. The three holes 343 on one side of the first connecting rod 340 are hinged to the second shaft 352 on the other side of the second connecting rod 350, and the two holes 342 in the middle of the first connecting rod 340 are hinged to the rotating rod shaft 334 on one side of the rotating rod 330.

[0025] refer to Figures 5 to 13 The lower part of the injection seat 310 is provided with two upper and lower guide holes 314, the injection tube 370 is slidably connected to the guide holes 314, the retaining ring 372 in the middle of the injection tube 370 is arranged in the middle of the two guide holes 314, the rotating rod 330 and the injection tube 370 are connected through the No. 4 connecting rod 390, one side of the No. 4 connecting rod 390 is hinged to the rotating rod shaft 334 on one side of the rotating rod 330, and the other side of the No. 4 connecting rod 390 is hinged to the injection tube dumpling shaft 371 on the upper part of the injection tube 370.

[0026] refer to Figures 5 to 13 A spring 410 is provided between the injection tube 370 and the injection seat 310. The spring 410 is sleeved on the outside of the injection tube 370. The upper part of the injection tube 370 abuts against the upper guide hole 314, and the lower part of the No. 3 connecting rod 380 abuts against the retaining ring 372 in the middle of the injection tube 370.

[0027] refer to Figures 5 to 13The injection tube 370 is internally slidably connected to the piston 360, and the piston 360 and the No. 1 connecting rod 340 are connected by connecting the No. 3 connecting rod 380. One side of the No. 3 connecting rod 380 is hinged to the No. 1 shaft 351 on the upper part of the piston 360, and the other side of the No. 3 connecting rod 380 is hinged to the three holes 343 on the side of the No. 1 connecting rod 340. Since the No. 2 connecting rod 350 is hinged to the injection seat 310, the No. 2 connecting rod 350 is hinged to one side of the No. 1 connecting rod 340, and the rotating rod 330 and the No. 1 connecting rod 340 are hinged in the middle, when the driving rod 320 drives the rotating rod 330 to rotate, the rotating rod 330 drives the No. 1 connecting rod 340 to swing, and when the No. 1 connecting rod 340 swings, the piston 360 is driven up and down through the No. 3 connecting rod 380, and when the No. 1 connecting rod 340 swings, the injection tube 370 is driven up and down through the No. 4 connecting rod 390, and when the No. 1 connecting rod 340 swings, the No. 1 hole 341 and the No. 2 hole 342 are not obtained. The same rotation radius, the rotation radius at the first hole 341 is greater than the rotation radius at the second hole 342, so the piston 360 and the injection tube 370 move different distances, the volume between the piston 360 and the injection tube 370 will change, when the piston 360 and the injection tube 370 move upward, the volume between the piston 360 and the injection tube 370 becomes larger, and the injection tube 370 starts to absorb fertilizer water, when the piston 360 and the injection tube 370 move downward, the volume between the piston 360 and 270 becomes smaller, and the injection tube 370 starts to inject fertilizer water.

[0028] When the piston 360 and the injection tube 370 move upward, the driving rod 320 drives the No. 1 connecting rod 340 to swing upward through the rotating rod 330. At this time, the spring 410 is compressed. When the piston 360 and the injection tube 370 rise to the upper limit position, the rotating rod 330 rotates to the upper vertical direction. At this time, the rotating rod 330 will move downward rapidly under the action of the elastic potential energy of the spring 410, which can ensure that the insertion rod 374 at the lower part of the injection tube 370 is quickly inserted into the soil. At this time, the driving rod 320 and the lower bearing seat 313 are disengaged. When the driving rod 320 continues to rotate, the driving rod 320 will contact the lower bearing seat 313 again. At this time, the driving rod 320 drives the rotating rod 330 to rotate again. At this time, the piston 360 and the injection tube 370 begin to rise. When the rotating rod 330 moves to a certain upper position again, the injection tube 370 is separated from the soil. At this time, the motor 440 stops rotating, and the piston 360 and the injection tube 370 remain in their current position.

[0029] refer to Fig.13 , Figure 3 The first hole 341 and the second hole 342 of the first connecting rod 340 are respectively provided with multiple holes. When the injection depth and the amount of fertilizer and water injection need to be adjusted, different first holes 341, second holes 342 and the third connecting rod 380 and the fourth connecting rod 390 can be hinged.

[0030] refer to Figures 5 to 13The lower part of the injection tube 370 is provided with an insertion rod 374, and fertilizer holes 375 are evenly distributed around the insertion rod 374. The outer side of the insertion rod 374 is slidably connected to the sealing tube 112 at the lower part of the trolley 110. When the injection tube 370 is in the upper position, the fertilizer hole 375 is in the sealing tube 112, and the fertilizer water in the fertilizer hole 375 will not leak out. When the injection tube 370 descends, the fertilizer inlet pipe 375 that leaks out of the sealing tube 112 is inserted into the soil, so that the fertilizer water can only be injected into the soil.

[0031] refer to Figure 4 The front side of the trolley 110 is provided with a fertilizer suction device 200, which includes a fertilizer water bucket 210, a fertilizer water outlet 211 is provided on the lower side of the fertilizer water bucket 210, and an opening and closing valve 220 is hinged on the side of the fertilizer water outlet 211. The outer side of the fertilizer water outlet 211 is connected to the outer cover 230, and the outer cover 230 and the fertilizer inlet pipe 373 at the lower part of the retaining ring 372 are connected by a hose. When the piston 360 and the injection tube 370 move upward, the volume between the piston 360 and the injection tube 370 increases, the injection tube 370 starts to absorb fertilizer water, and the opening and closing valve 220 opens. When the piston 360 and the injection tube 370 move downward, the volume between the piston 360 and 270 decreases, the injection tube 370 starts to inject fertilizer water, and the opening and closing valve 220 closes.

[0032] A method for using a soil remediation fertilization device. When using the device, fertilizer water is placed in a fertilizer water bucket 210, and the device is pushed to move to a position where fertilizer is required, and the motor 440 is started. After the motor 440 rotates, the injection tube 370 moves downward rapidly, and the insertion rod 374 at the lower part of the injection tube 370 is inserted into the soil, and at the same time, it is sucked into the fertilizer water cup between the piston 360 and the injection tube 370 and injected into the soil. After the fertilizer water is injected, the injection tube 370 moves upward, and the insertion rod 374 is pulled out of the soil, pushing the device to the next fertilizer injection position, and repeating the above process. The first hole 341 and the second hole 342 of the No. 1 connecting rod 340 are respectively provided with multiple holes. When it is necessary to adjust the injection depth and the amount of fertilizer water injection, different first holes 341, second holes 342 and the third connecting rod 380 and the fourth connecting rod 390 can be hinged.

[0033] Since the No. 2 connecting rod 350 is hinged to the injection seat 310, the No. 2 connecting rod 350 is hinged to one side of the No. 1 connecting rod 340, and the rotating rod 330 and the No. 1 connecting rod 340 are hinged in the middle, when the driving rod 320 drives the rotating rod 330 to rotate, the rotating rod 330 drives the No. 1 connecting rod 340 to swing, and when the No. 1 connecting rod 340 swings, the piston 360 is driven up and down through the No. 3 connecting rod 380, and when the No. 1 connecting rod 340 swings, the injection tube 370 is driven up and down through the No. 4 connecting rod 390. When the No. 1 connecting rod 340 swings, the first hole 341 and the second hole 342 are not moved. The same rotation radius, the rotation radius at the first hole 341 is greater than the rotation radius at the second hole 342, so the piston 360 and the injection tube 370 move at different distances, the volume between the piston 360 and the injection tube 370 will change, when the piston 360 and the injection tube 370 move upward, the volume between the piston 360 and the injection tube 370 becomes larger, and the injection tube 370 starts to absorb fertilizer water, when the piston 360 and the injection tube 370 move downward, the volume between the piston 360 and 270 becomes smaller, and the injection tube 370 starts to inject fertilizer water. Since the piston 360 and the injection tube 370 move upward or downward synchronously, the insertion and fertilization are carried out simultaneously, the insertion depth and the amount of fertilizer are uniform, and the elastic potential energy of the spring 410 enables the insertion rod 374 at the bottom of the injection tube 370 to be quickly inserted into the soil without external force, thereby increasing the speed of fertilization, achieving good soil repair effect, automatic insertion and fertilization, high fertilization efficiency, and low labor intensity.
