[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) The heavy metal contaminated soil remediation machine, through the coordinated use of a water spray pipe, a first motor, a nozzle, a support rod, a fixed plate and a filter plate, can put heavy metal contaminated soil into the installation cylinder through the feed trough. The heavy metal contaminated soil falls above the fixed plate. Chemical leaching agent is introduced into the water spray pipe through the water inlet pipe, so that the nozzle leaches the heavy metal contaminated soil in the installation cylinder. After leaching is completed, the first motor is started, which drives the water spray pipe to rotate forward, driving the support rod, fixed plate and filter plate to rotate.

[0012] (2) This heavy metal contaminated soil remediation machine, through the combined use of a second motor, a rotating rod, a rotating plate, and a shaftless spiral blade, allows wastewater to flow into the discharge box through an opening. Controlling the start of the second motor causes the rotating rod to rotate, which in turn drives the rotating plate to rotate, causing the shaftless spiral blade to rotate and discharge the wastewater. Controlling the start of the first motor causes the spray pipe to reverse, which in turn drives the fixed plate to reverse, allowing the soil on the fixed plate to fall into the discharge box through the space between the two sets of support rods. Controlling the start of the second motor causes the rotating rod to rotate, which in turn drives the rotating plate to rotate, causing the shaftless spiral blade to rotate and discharge the moist soil. The shaftless design of the shaftless spiral blade avoids material accumulation on the central shaft, reduces soil residue in the device, prevents accumulation and blockage in the device, reduces labor burden, saves soil resources, and improves the device's performance and service life.

[0016] Furthermore, the filtration mechanism 2 also includes a first motor 202, a nozzle 203, and a filter plate 206. The first motor 202 is fixedly installed on the outside of the mounting cylinder 1. The output shaft of the first motor 202 is fixedly installed on a water spray pipe 201. Multiple sets of spray nozzles are opened on the outside of the water spray pipe 201. The nozzle 203 is fixedly installed inside the spray nozzle. The filter plate 206 is fixedly installed between the fixing plate 205 and the water spray pipe 201. A water inlet is opened on the outside of the water spray pipe 201. A water inlet pipe is rotatably installed inside the water inlet. Two sets of scrapers 8 are fixedly installed on the outside of the fixing plate 205. The outside of the scrapers 8 is inclined. The soil contaminated with heavy metals can be placed into the installation cylinder 1 through the feed trough 6. The soil contaminated with heavy metals falls above the fixed plate 205. Chemical leaching agent is introduced into the spray pipe 201 through the water inlet pipe 9, so that the spray head 203 leaches the soil contaminated with heavy metals in the installation cylinder 1. After leaching is completed, the first motor 202 is started, which drives the spray pipe 201 to rotate forward, which in turn drives the support rod 204, the fixed plate 205 and the filter plate 206 to rotate. At this time, the fixed plate 205 no longer closes the opening, and the filter plate 206 rotates to a vertical position to separate the soil and wastewater, thereby accelerating the solid-liquid separation speed.

[0017] The discharge mechanism 3 includes a second motor 301, a rotating rod 302, a rotating plate 303, and a shaftless spiral blade 304. The second motor 301 is fixedly installed on the outside of the discharge box 4.

The shaftless spiral blade 304 is fixedly installed on the outside of the rotating plate 303 and rotatably installed inside the discharge box 4, allowing wastewater to flow into the discharge box 4 through the opening. This controls the second motor 301. The starting of motor 301 causes the rotating rod 302 to rotate, which in turn rotates the rotating plate 303, causing the shaftless spiral blade 304 to rotate and discharge wastewater. The starting of the first motor 202 causes the water spray pipe 201 to reverse, which in turn causes the fixed plate 205 to reverse, allowing the soil on the fixed plate 205 to pass through the space between the two sets of support rods 204 and fall into the discharge box 4. The starting of the second motor 301 causes the rotating rod 302 to rotate, which in turn rotates the rotating plate 303, causing the shaftless spiral blade 304 to rotate and discharge moist soil. The shaftless design of the shaftless spiral blade 304 avoids material accumulation on the central shaft, reduces soil residue in the device, prevents blockages, and conserves soil resources.

[0018] Furthermore, a discharge port is provided on the outer side of the discharge box 4, and a discharge plate 7 is fixedly installed on the inner and outer sides of the discharge port.

[0019] Working principle: Heavy metal contaminated soil is placed into the installation cylinder 1 through the feed trough 6. The baffle 5 prevents the heavy metal contaminated soil from falling onto the filter plate 206, allowing it to fall above the fixed plate 205. Chemical leaching agent is introduced into the spray pipe 201 through the water inlet pipe 9, causing the spray nozzle 203 to leach the heavy metal contaminated soil in the installation cylinder 1. After leaching, the first motor 202 is started, causing the spray pipe 201 to rotate forward, which in turn rotates the support rod 204, the fixed plate 205, and the filter plate 206. At this time, the fixed plate 205 no longer closes the opening, and the filter plate 206 rotates to a vertical position to separate the soil from the wastewater, allowing the wastewater to... The wastewater flows into the discharge box 4 through the opening. The second motor 301 is started, causing the rotating rod 302 to rotate, which in turn rotates the rotating plate 303, causing the shaftless spiral blade 304 to rotate and discharge the wastewater. The first motor 202 is started, causing the water spray pipe 201 to reverse, which in turn rotates the fixed plate 205, causing the soil on the fixed plate 205 to fall into the discharge box 4 through the two sets of support rods 204. This causes the scraper 8 to rotate and clean the inner wall of the mounting cylinder 1. The second motor 301 is started, causing the rotating rod 302 to rotate, which in turn rotates the rotating plate 303, causing the shaftless spiral blade 304 to rotate and discharge the moist soil, raising the discharge plate 7 to discharge it to the outside.
