Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a soil remediation agent spraying device. Background Technology

[0002] Soil remediation is a technical measure to restore contaminated soil to its normal function. It usually uses soil remediation agents, which include solid and liquid forms. Solid soil remediation agents are applied directly to the soil surface and mixed with soil through tilling. They are used to fix heavy metals or organic pollutants, reduce their mobility and toxicity, adjust soil pH, increase organic matter, or improve soil structure. Liquid soil remediation agents are sprayed, injected, or leached directly into the soil for in-situ remediation (such as chemical oxidation to degrade organic pollutants).

[0003] A search revealed a Chinese patent (application number "201921451345.3") disclosing a "soil remediation agent spraying device." This spraying device includes a base plate with support columns fixedly connected to its four corners. Rollers are engaged at the bottom of the support columns. A mixing tank is fixedly connected to the center of the top of the base plate. Adjustment boxes are fixedly connected to the left and right sides of the top of the base plate. A protective shell is fixedly connected to the top of the mixing tank. A motor is fixedly connected to the center of the top of the mixing tank. A remediation agent placement pipe is fixedly connected to the right side of the top of the mixing tank. A telescopic hose is fitted onto the top of the water pump. A second conduit is fitted to the other end of the telescopic hose. A nozzle is fitted to the end of the second conduit. A fixing rod is fixedly connected to the connection between the second conduit and the telescopic hose. The other end of the fixing rod is fixedly connected to the adjustment rod. However, during use, some liquid soil remediation agent cannot directly contact the soil, resulting in waste of the soil remediation agent and low soil remediation efficiency. Utility Model Content

[0004] This invention provides a soil remediation agent spraying device, which solves the problem that, in the spraying device proposed in the prior art, some liquid soil remediation agent cannot directly contact the soil, resulting in waste of soil remediation agent and low soil remediation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A soil remediation agent spraying device includes a base plate, a storage mechanism on the top of the base plate, the storage mechanism including a water storage cylinder and a cylinder cover bolted to the outer wall of the top of the water storage cylinder, a stirring assembly inside the water storage cylinder, the stirring assembly including a drive shaft passing through and connected to the outer wall of the cylinder cover via a bearing, several stirring frames welded to the outer wall of the drive shaft, a stirring motor, and a rotating shaft connected to the bottom end of the output shaft of the stirring motor via a coupling, a spraying mechanism on the top of the base plate including a delivery pump bolted to the outer wall of the top of the base plate, a distribution pipe and several spray heads respectively fixed to the inner wall of the bottom of the distribution pipe, two soil loosening mechanisms on one side of the base plate, the soil loosening mechanism including a lifting cylinder bolted to the outer wall of the top of the base plate, a connecting plate bolted to the bottom end of the piston rod of the lifting cylinder and several soil loosening cutters respectively welded to the outer wall of the bottom of the connecting plate.

[0007] Preferably, the four corners of the bottom of the base plate are each bolted with a universal wheel with brake, and two handles are welded to the outer wall of the top side of the base plate.

[0008] Preferably, a support frame is welded to the outer wall of the bottom of the water storage cylinder, and the support frame is bolted to the outer wall of the top of the base plate. A feed hopper is provided through and fixed to the outer wall of the cylinder cover, and a drain pipe is fixed to the inner wall of the bottom of the water storage cylinder.

[0009] Preferably, several stirring frames are respectively abutted against the inner wall of the water storage tank. A mounting bracket is welded to the top outer wall of the tank cover, and the stirring motor is bolted to the top outer wall of the mounting bracket. The lower part of the rotating shaft is connected to the top outer wall of the tank cover through a bearing seat, and a driving synchronous belt is connected to the upper outer wall of the rotating shaft through a pin. A driven synchronous belt is connected to the upper outer wall of the transmission shaft through a pin, and the driven synchronous belt forms a transmission engagement with the synchronous belt.

[0010] The above scheme uses the output shaft of the stirring motor to drive the rotating shaft to rotate, which in turn causes the transmission shaft and the stirring frame to rotate via the synchronous belt. The feed hopper delivers the soil remediation agent and clean water into the water storage tank, and the rotating stirring frame mixes the soil remediation agent and clean water.

[0011] Preferably, the inlet end of the delivery pump is connected to the outer wall of one end of the drain pipe via a flange, and the outlet end of the delivery pump is connected to a delivery pipe via a flange. The lower part of the delivery pipe passes through and is fixed to the outer wall of the base plate, and the distribution pipe is fixed to the lower outer wall of the delivery pipe.

[0012] The above method involves using a pump to deliver the diluted soil remediation agent to a distribution pipe, which then delivers the diluted agent to a spray head, which sprays the agent directly onto the soil surface.

[0013] Preferably, two limiting rods are bolted to the top outer wall of the connecting plate, and the two limiting rods are respectively inserted through and slidably installed on the outer wall of the base plate.

[0014] The above method involves lowering the piston rod of the lifting cylinder, which in turn lowers the connecting plate and multiple loosening cutters. The bottom of the loosening cutters penetrates deep into the soil, and then the entire device moves, causing the loosening cutters to loosen the soil and allow the soil remediation agent to come into contact with the deeper soil layers.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The delivery pump delivers the mixed and diluted soil remediation agent to the distribution pipe, which then delivers the diluted soil remediation agent to the spray head. The spray head sprays the diluted soil remediation agent directly onto the soil surface, which avoids waste and improves soil remediation efficiency.

[0017] 2. The piston rod of the lifting cylinder descends, causing the connecting plate and multiple loosening cutters to descend as well. The bottom of the loosening cutters penetrates deep into the soil, and then the entire device moves. The loosening cutters loosen the soil, allowing the soil remediation agent to come into contact with the deeper soil layers. This loosening of the soil allows the soil remediation agent to directly mix with the soil, improving soil remediation efficiency.

[0018] In summary, this invention allows the soil remediation agent to be sprayed directly onto the soil, avoiding waste, and loosens the soil, allowing the soil remediation agent to directly contact and mix with the soil, thus improving soil remediation efficiency. Attached Figure Description
