Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a device for remediating heavy metal contaminated soil in gardens. Background Technology

[0002] Existing technologies for remediating heavy metal-contaminated soil in gardens often employ a step-by-step operation mode, which involves first tilling the soil separately and then spraying the remediation solution. This process is cumbersome, time-consuming, and inefficient. Furthermore, traditional equipment struggles to adjust the working depth flexibly according to different garden soil conditions and terrain, exhibiting poor adaptability to complex terrains. Additionally, the remediation solution is not sprayed evenly enough and does not mix sufficiently with the soil, affecting the remediation effect. Moreover, the equipment has a complex structure and is inconvenient to maintain, making it difficult to meet the needs of efficient and precise garden soil remediation. This has brought certain adverse effects to users. To address the shortcomings of existing technologies, we propose a remediation device for heavy metal-contaminated soil in gardens. Utility Model Content

[0003] The main purpose of this invention is to provide a soil remediation device for heavy metal contaminated landscaping, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A soil remediation device for heavy metal contaminated landscaping includes an installation plate and connectors fixedly installed on one side of the installation plate. A first servo motor is detachably connected to the top of the installation plate, and a threaded rod is detachably connected to the output shaft of the first servo motor. Two guide rods are symmetrically arranged inside the installation plate, and movable blocks are provided on the outer surfaces of the threaded rods and the two guide rods. An installation block is detachably connected to one side of multiple movable blocks. A liquid storage tank is fixedly connected to the upper end of the installation block, and two liquid injection ports are symmetrically arranged on the top of the liquid storage tank. A rotary tillage bin is fixedly connected to one side of the installation block, and a rectangular frame is fixedly connected to the top of the rotary tillage bin. A diversion bin is provided inside the rectangular frame. A water pump is detachably connected to the upper end of the diversion bin, a suction pipe is detachably connected to one side of the water pump, and a delivery pipe is detachably connected to one end of the water pump. A nozzle is detachably connected to the lower end of the diversion bin.

[0006] A second servo motor is detachably connected to one end of the rotary tiller. The output shaft of the second servo motor passes through the rotary tiller and is detachably connected to a rotating rod. A fixed plate is fixedly connected to the outer surface of the rotating rod, and rotary tiller blades are detachably connected to one side of the fixed plate.

[0007] Preferably, the output shaft of the first servo motor is detachably connected to the threaded rod via a coupling, one of the moving blocks is threadedly connected to the outer surface of the threaded rod, and the other two moving blocks are slidably connected to the outer surfaces of the two guide rods respectively.

[0008] Preferably, one end of the suction pipe is detachably connected to the water pump, and the other end is inserted into the storage tank; one end of the infusion pipe is detachably connected to the water pump, and the other end is connected to the diversion chamber.

[0009] Preferably, the nozzles are linearly distributed at equal intervals at the lower end of the diversion chamber, and the spraying direction of the nozzles is perpendicular to the soil turning path of the rotary tillage chamber.

[0010] Preferably, the output shaft of the second servo motor is detachably connected to the rotating rod via a coupling, and several fixed disks are provided and evenly fixedly connected to the outer surface of the rotating rod.

[0011] Preferably, the rotary tillage blades are provided in a plurality of units and are uniformly and detachably connected to one side surface of the fixed disc by bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This garden heavy metal contaminated soil remediation device, through its first servo motor, causes the threaded rod to rotate when the motor starts. The moving block, which is threadedly connected to the threaded rod, moves axially, thereby driving the installation block and rotary tillage bin to adjust their height. This allows the device to flexibly adjust the distance between the bottom of the rotary tillage bin and the soil surface according to different garden soil conditions and operational needs, greatly improving the device's adaptability to different terrains and soil conditions and broadening its application range.

[0014] This soil remediation device for heavy metal contaminated landscaping uses a second servo motor to drive a rotating rod and rotary tiller blades to rotate at high speed, thus tilling and breaking up the soil. At the same time, a water pump draws remediation solution from the storage tank and sprays it evenly from evenly spaced nozzles along a direction perpendicular to the tilling path through a distribution chamber. This integrated operation mode, which combines tilling and spraying simultaneously, avoids the cumbersome process of traditional step-by-step operations, reduces the number of steps and time required, and significantly improves the efficiency of soil remediation.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a soil remediation device for heavy metal contaminated landscaping includes a mounting plate 1 and a connector 2. The connector 2 is fixedly installed on one side of the mounting plate 1 and is used to mount the device to a tractor or other mobile equipment to enable mobile operation. A first servo motor 3 is detachably mounted on the top of the mounting plate 1 by bolts. Its output shaft is connected to a threaded rod 4 through a coupling. When the first servo motor 3 is started, the threaded rod 4 rotates synchronously. Two guide rods 5 are symmetrically arranged inside the mounting plate 1. Movable blocks 6 are provided on the outer surfaces of both the threaded rod 4 and the guide rods 5. One of the movable blocks 6 is threadedly connected to the threaded rod 4, and the other two movable blocks 6 are slidably connected to the two guide rods 5 respectively. When the threaded rod 4 rotates, the threaded movable blocks 6 will move along the axial direction of the threaded rod 4, thereby enabling the mounting block 7 and the rotary tillage chamber 10 to be adjusted in height.

[0022] Three movable blocks 6 are detachably connected to an installation block 7 by bolts on one side. A storage tank 8 is fixedly connected to the upper end of the installation block 7. The top of the storage tank 8 is provided with two injection ports 9 for injecting heavy metal remediation liquid. A rotary tillage bin 10 is fixedly connected to one side of the installation block 7. A rectangular frame 11 is fixedly connected to the top of the rotary tillage bin 10. A diversion bin 12 is installed inside the rectangular frame 11. A water pump 13 is detachably connected to the upper end of the diversion bin 12 by bolts. One side of the pump is connected to a suction pipe 14, and the other side is connected to a delivery pipe 15. The other end of the suction pipe 14 is inserted into the storage tank 8 for extracting the remediation liquid. The other end of the delivery pipe 15 is connected to the inside of the diversion bin 12 to deliver the remediation liquid to the diversion bin 12. Multiple nozzles 16 are linearly distributed at equal intervals at the lower end of the diversion bin 12. The spraying direction of the nozzles 16 is perpendicular to the soil tillage path of the rotary tillage bin 10 to ensure that the remediation liquid evenly covers the soil surface after tillage.

[0023] One end of the rotary tiller 10 is detachably connected to a second servo motor 17 via bolts. Its output shaft passes through the rotary tiller 10 via a coupling and is connected to a rotating rod 18. Multiple fixed discs 19 are evenly fixed on the outer surface of the rotating rod 18. Multiple rotary tiller blades 20 are detachably connected to one side of each fixed disc 19 via bolts. When the second servo motor 17 is started, the rotating rod 18 drives the fixed discs 19 and the rotary tiller blades 20 to rotate at high speed, thereby turning and breaking up the soil. The detachable design of the rotary tiller blades 20 facilitates quick replacement after wear.

[0024] It should be noted that this utility model is a soil remediation device for heavy metal pollution in gardens. In use, the device is first fixed to a mobile device such as a tractor through the connector 2. The distance between the bottom of the rotary tillage bin 10 and the soil surface is adjusted, and the tightness of the connection of the first servo motor 3, the second servo motor 17 and other components on the mounting plate 1 is checked. Then, the liquid extraction pipe 14, the liquid delivery pipe 15 and the circuit are connected, and the start and stop functions of the first servo motor 3, the second servo motor 17 and the water pump 13 are tested. Then, the heavy metal remediation liquid is injected through the liquid injection port 9 at the top of the liquid storage tank 8, and the sealing cap is tightened. When operating, the mobile device is started, the first servo motor 3 drives the threaded rod 4 to move the moving block 6 and the rotary tillage bin 10 to a suitable position. Then, the second servo motor 17 synchronously drives the rotating rod 18 and the rotary tillage blades 20 to till the soil. At the same time, the water pump 13 draws the remediation liquid in the liquid storage tank 8 and sprays it evenly through the diversion chamber 12 from the equally spaced nozzles 16 along the direction perpendicular to the tillage path, realizing the integrated operation of tillage and spraying.
