Description

Technical Field

[0001] The utility model belongs to the technical field of soil remediation, and specifically relates to a multi-directional spraying mechanism for soil remediation agents. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of polluted soil, which is repaired through physical or chemical technologies. The saline soil in Qinghai is widely distributed. Soil salinization will make the soil's water permeability and air permeability worse, and reduce the soil's water and fertilizer retention capacity. It is necessary to repair the salinized soil. Spraying remediation agents is a means of soil remediation. Therefore, a spraying mechanism is needed to spray the remediation agents on the saline land in Qinghai.

[0003] Among them, through retrieval, it is found that there is an application with the application number CN202020565042.0, which discloses a remediation liquid spraying device with good spraying effect for soil remediation, including a support bottom plate. Moving wheels are fixedly installed at the four corners of the bottom of the support bottom plate. The soil remediation liquid is added into the storage tank through the liquid adding port, adsorbed by a water pump and then conveyed to the connection shell through an infusion hose and a connecting pipe. When the remediation liquid needs to be sprayed, the driving motor drives the driving gear to rotate, and the meshing gear ring drives the rotating sleeve to rotate under the connection of the annular plate, thereby driving the connection shell to rotate. The remediation liquid in the connection shell is sprayed from the four liquid spraying heads under the action of centrifugal force. During the spraying process, the air cylinder drives the lifting plate to slowly rise or fall, so as to slowly adjust the spraying range. The remediation liquid spraying device with good spraying effect for soil remediation has a reasonable structural design and is convenient to use. It adopts a semi-automatic spraying method, without too much manual operation, saving time and effort, improving work efficiency, and can ensure the uniformity of spraying, which is beneficial to the rapid repair of soil, meets the multi-directional use requirements. By setting a push handle, the device can be pushed in cooperation with the moving wheels, improving the practicability. By setting a stabilizing shell, the stability of the driving motor during installation is improved, preventing it from falling off. The heat dissipation holes are beneficial to the heat dissipation of the driving motor. By setting rolling balls, the friction between the inner wall of the annular groove and the surface of the annular plate when the rotating sleeve rotates is reduced. By setting a sealing ring, the remediation liquid in the connection shell is prevented from leaking out from the gap between the connecting pipe and it. By setting a reinforcing rib, the fixing degree of the connection between the connecting pipe and the lifting plate is strengthened, preventing the connecting pipe from falling off.

[0004] However, through research, it is found that: this device only drives the driving gear to rotate through the driving motor, and then makes the connection shell rotate to spray the remediation liquid to increase the spraying area. The spraying area is not large enough, the spraying effect is not good enough, and there is no structure for crushing and tilling the soil. The soil is agglomerated together, and it is not easy for the inner layer of the soil to come into contact with the remediation liquid, and the remediation effect on the soil is not good enough. Therefore, a new device is provided to solve this problem. Content of the Utility Model
