[0006] The effect achieved by the above components is: under the action of the anti-blocking device, the injection head will not be blocked when inserted into the soil. When the contaminated soil needs to be pretreated, the injection barrel is placed vertically to the ground, and the pedal is stepped on to insert the injection barrel into the soil through the injection head. Under the action of the anti-blocking device, the injection head will not be blocked by the soil, resulting in the problem that the medicine cannot be injected into the soil. After the slider contacts the ground, the injection barrel is pressed down, so that the baffle is pulled out by the pull rope, and the push rod is pressed down, so that the medicine inside the injection barrel is injected into the soil, thereby achieving the effect of pretreatment of contaminated soil.

When it is necessary to pretreat the contaminated soil, the syringe 1 is placed perpendicular to the ground, and the pedal is stepped on, so that the syringe 1 is inserted into the soil through the injection head 5. Under the action of the anti-blocking device 2, the injection head 5 will not be blocked by the soil, resulting in the problem that the liquid medicine cannot be injected into the soil. After the slider contacts the ground, the syringe 1 is pressed down, so that the baffle 7 is pulled out through the pull rope 8, and the push rod 4 is pressed down, so that the medicine inside the syringe 1 is injected into the soil, thereby achieving the effect of pretreating the contaminated soil.
[0029] Reference Figure 2The anti-blocking device 2 includes a groove 21 formed on the surface of the injection barrel 1. A fixing rod is fixedly connected to the inside of the groove 21. A rectangular plate 23 is slidably connected to the surface of the fixing rod. A traction rope 24 is fixedly connected to the bottom of the rectangular plate 23. The other end of the traction rope 24 is fixedly connected to the side of the injection head 5. A hinge 25 is fixedly connected to the side of the injection head 5. The hinge 25 connects one end of the injection barrel 1 with one end of the injection head 5. Under the action of the anti-blocking device 2, the injection head 5 will not be blocked when it is inserted into the soil. When it is necessary to pre-treat the contaminated soil, the injection barrel 1 is placed vertically to the ground and stepped on. The pedal allows the syringe 1 to be inserted into the soil through the injection head 5. Under the action of the anti-blocking device 2, the injection head 5 will not be blocked by the soil, which will cause the liquid medicine to be unable to be injected into the soil. When the slider contacts the ground, the syringe 1 is pressed down, so that the baffle 7 is pulled out through the pull rope 8, and the push rod 4 is pressed down, so that the medicine inside the syringe 1 is injected into the soil, thereby achieving the effect of pre-treatment of contaminated soil. The inner wall of the injection head 5 is fixedly connected to the first spring 27, and the two ends of the first spring 27 are respectively fixedly connected to the inner wall of the opposite injection head 5. Under the action of the first spring 27, the injection head 5 divided into four petals can be moved in when not in use. The second spring 22 is provided on the surface of the fixing rod, and the two ends of the second spring 22 are fixedly connected to the inner wall of the groove 21 and the bottom of the rectangular plate 23. Under the action of the second spring 22, when the syringe 1 is not in use, the rectangular plate 23 can be reset, so that the injection head 5 is reset, thereby achieving the reset effect. A pad 26 is fixedly connected to the side of the injection head 5. The pad 26 is a rubber pad. Under the action of the pad 26, the injection head 5 does not have a rigid contact with the injection head 5 when it is reset. When the syringe 1 needs to be used, the syringe 1 is placed on the ground. In a vertical state, step on the pedal to insert the injection head 5 into the soil. When the soil contacts the rectangular plate 23, press the injection cylinder 1 again to move the rectangular plate 23 upward, thereby driving the traction rope 24 to pull the injection head 5 open. At the same time, under the action of the pull rope 8 and the slider, the baffle 7 is also pulled out, and the medicine is injected into the soil. After the injection is completed, pull the injection cylinder 1 upward. Under the action of the second spring 22 and the first spring 27, the injection head 5 shrinks into a cone shape. Under the action of the pad 26, the injection head 5 will not be in rigid contact with the injection head 5 when it is reset, thereby achieving the effect of anti-blocking.
[0030] Reference Figure 3-4The dosing device 3 includes an annular groove 32 opened on the surface of the push rod 4, and a snap ring 34 is provided inside the annular groove 32. One end of the injection cylinder 1 is fixedly connected to a rectangular block 31, and the side of the rectangular block 31 is fixedly connected to a telescopic rod 35. The other end of the telescopic rod 35 is fixedly connected to the side of the snap ring 34. Under the action of the snap ring 34 and the annular groove 32, the push rod 4 can be quantitatively moved when pushed, thereby achieving the quantitative effect. A third spring 36 is provided on the surface of the telescopic rod 35. The two ends of the third spring 36 are respectively fixedly connected to the side of the rectangular block 31 and the side of the snap ring 34. Under the action of the third spring 36, the snap ring 34 can be tightly attached to the inside of the annular groove 32, thereby achieving the effect of limiting the push rod 4. The inner wall of the annular groove 32 is provided with a slope 33. The upper and lower inner walls of the annular groove 32 are provided with slopes 33. Under the action of the slope 33, the push rod 4 will not be affected by the snap ring during the pushing process. The positive and negative poles of the magnet 37 and the magnetic block are attracted to each other, so that the two snap rings 34 can form a circular ring and be stuck in the inner part of the ring groove 32. When the push rod 4 is pushed to inject the medicine, the snap ring 34 and the ring groove 32 can be used to inject the medicine in a quantitative manner. Under the action of the third spring 36, the snap ring 34 can be tightly attached to the inner part of the ring groove 32. Under the action of the slope 33, the push rod 4 will not be subjected to the great force of the snap ring 34 during the pushing process, thereby achieving the effect of saving effort. Under the action of the positive and negative poles of the magnet 37 and the magnetic block, the two snap rings 34 can form a circular ring and be stuck in the inner part of the ring groove 32, thereby achieving the effect of quantitative injection.
[0031] Working principle: when it is necessary to use the contaminated soil pretreatment equipment, when it is necessary to pretreat the contaminated soil, the syringe 1 is placed vertically to the ground, and the pedal is stepped on, so that the syringe 1 is inserted into the soil through the injection head 5. Under the action of the anti-blocking device 2, the injection head 5 will not be blocked by the soil, which will cause the liquid medicine to be unable to be injected into the soil. After the slider contacts the ground, the syringe 1 is pressed down, so that the baffle 7 is pulled out through the pull rope 8, and the push rod 4 is pressed down, so that the medicine inside the syringe 1 is injected into the soil, thereby achieving the effect of pretreating the contaminated soil. When it is necessary to use the syringe 1, the syringe 1 is placed vertically to the ground, and the pedal is stepped on, so that the injection head 5 is inserted into the soil. When the soil contacts the rectangular plate 23, the syringe 1 is pressed down again, so that the rectangular plate 23 moves up, thereby driving the traction rope 24 to pull the injection head 5 open. At the same time, under the action of the pull rope 8 and the slider, the baffle The plate 7 is also pulled out, and the medicine is injected into the soil. After the injection is completed, the injection cylinder 1 is pulled out upward. Under the action of the second spring 22 and the first spring 27, the injection head 5 shrinks into a cone shape. Under the action of the pad 26, the injection head 5 does not have a rigid contact with the injection head 5 when it is reset, thereby achieving the effect of anti-blocking. When the push rod 4 is pushed to inject the medicine, under the action of the snap ring 34 and the annular groove 32, the medicine can be injected quantitatively. Under the action of the third spring 36, the snap ring 34 can be tightly attached to the inside of the annular groove 32. Under the action of the slope 33, the push rod 4 will not be subjected to a large force from the snap ring 34 during the pushing process, thereby achieving the effect of saving effort. Under the action of the attraction between the positive and negative poles of the magnet 37 and the magnetic block, the two snap rings 34 can form a circular ring stuck in the inside of the annular groove 32, thereby achieving the effect of quantitative.
