The two adjustment plates 202 are symmetrically arranged about each nozzle 105. A driving mechanism for driving the two adjustment plates 202 is provided on one of the two L-shaped plates 201.

[0034] It should be noted here that: through the setting of the adjustment mechanism, under the driving action of the driving mechanism, the two adjustment plates 202 are driven to rotate away from or towards each other, so that the rotation angle between the two adjustment plates 202 is used to adjust the spraying range of the repair agent, so that the repair agent can be dispersed or gathered during the spraying process, thereby changing the spraying amount of the contaminated soil repair agent, and facilitating the adjustment of the spraying concentration of the agent according to the actual pollution situation of the soil to be repaired, thereby meeting the soil remediation needs while improving the efficiency and flexibility of soil remediation.

[0035] It is worth noting that the soil turning device 101 can refer to a rotary tiller, which is a prior art and will not be elaborated on here.

[0036] See also Figure 3-Figure 5 The connecting assembly shown in the figure includes a connecting plate 301 fixedly connected to the two L-shaped plates 201 on one side close to the adjusting plate 202, a connecting shaft 302 is rotatably connected between the two connecting plates 301, and one end of the adjusting plate 202 is fixedly connected to the connecting shaft 302;

[0037] It should be noted here that: through the setting of the connecting assembly, one end of the two adjustment plates 202 is rotatably connected to the L-shaped plate 201.

[0038] See also Figure 5The driving mechanism shown in the figure includes two fixed plates 401 fixedly connected to the side of the L-shaped plate 201 close to the soil, and the opposite sides of the two fixed plates 401 are connected to the racks 402 through the telescopic components, one end of the two connecting shafts 302 is set through the connecting plate 301, and is fixedly connected to the gears 403, the two gears 403 and the racks 402 are meshed with each other, and the L-shaped plate 201 is provided with a pushing mechanism for pushing the two racks 402;

[0039] It should be noted here that: by setting the driving mechanism, it is convenient to drive the two adjustment plates 202 to rotate towards or away from each other.

[0041] It should be noted here that: by setting the telescopic assembly, a guiding and resetting function is provided for the movement of the rack 402 .

[0042] Working principle: When remediating contaminated soil, a tractor is used to drive the soil turning device 101 to move in the farmland. During the movement of the soil turning device 101, the soil is turned while the repair agent is sprayed on the soil by the nozzle 105, so that the contaminated soil is repaired through the repair effect of the repair agent.

[0043] When repairing soil with different degrees of contamination, it is necessary to adjust the spraying amount of the repair agent according to the actual situation. When adjusting the spraying amount of the repair agent for contaminated soil, the two racks 402 are pushed to move closer to or away from each other under the action of the pushing mechanism, so that under the mutual meshing transmission action of the racks 402 and the gears 403, the adjustment plates 202 on the two connecting shafts 302 are driven to rotate away from or closer to each other, so that the rotation angle between the two adjustment plates 202 is used to block the spraying range of the repair agent of the nozzle 105. When the rotation angle of the two adjustment plates 202 is large, the spraying of the repair agent by the nozzle 105 will be expanded. When the rotation angle of the two adjustment plates 202 is small, the spraying range of the repair agent by the nozzle 105 will be reduced, so that the repair agent will be gathered, and the spraying amount of the repair agent on the contaminated soil surface will be increased accordingly. By adjusting the spraying range of the repair agent, the repair agent can be dispersed or gathered during the spraying process, thereby changing the spraying amount of the repair agent for the contaminated soil, making it easy to adjust the spraying concentration of the agent according to the actual pollution situation of the soil to be repaired, thereby meeting the needs of soil remediation while improving the efficiency and flexibility of soil remediation.

[0046] It should be noted here that: through the setting of the pushing mechanism, under the action of the moving component, the conical pushing block 602 will be driven to move up and down. In the process of the conical pushing block 602 moving up and down, through the mutual force and the guiding action of the telescopic component, the two pushing plates 601 will be pushed to move closer to or away from each other, thereby further pushing the two racks 402 to move closer to or away from each other.
