Description

Technical Field

[0001] The invention relates to the technical field of tillage devices, and in particular to a tillage device for repairing cultivated land soil polluted by heavy metals. Background Art

[0002] Heavy metal pollution in farmland is soil pollution caused by excessive deposition of heavy metals in waste. Heavy metals that pollute farmland soil mainly include elements with significant biological toxicity such as mercury, cadmium, lead, chromium and metalloid arsenic, as well as elements with certain toxicity such as zinc, copper and nickel. Heavy metal pollutants have low mobility in the soil, are not easily leached with water, and are not degraded by microorganisms. After entering the human body through the food chain, they have great potential harm. Special attention should be paid to preventing heavy metal pollution of farmland soil.

[0003] Soil contaminated by heavy metals is not suitable for growing crops, so it is necessary to plow the soil contaminated by heavy metals and add corresponding agents to the soil for repair treatment. When plowing the soil, a traction device (such as a tractor) is usually used to pull a plow to plow the soil.

[0004] Most of the existing tillage devices for repairing cultivated land soil are fixed installation structures, which are generally directly fixedly connected to the traction device by bolts, resulting in cumbersome installation and disassembly work with the traction device and inconvenient use. In addition, the plow body on the existing tillage devices for repairing cultivated land soil is mostly not convenient for lifting and adjusting, resulting in the inability to perform tillage operations at a fixed height, and it is also not convenient for adjusting the horizontal position, resulting in the spacing between adjacent plows being fixed and unchanged, and being unable to adapt to different tillage densities and having low applicability. Therefore, the present invention proposes a tillage device for repairing cultivated land soil contaminated by heavy metals to solve the problems existing in the prior art. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to propose a heavy metal contaminated farmland soil remediation tillage device to solve the problem that the existing farmland soil remediation tillage device is generally directly fixed to the traction device by bolts, resulting in cumbersome installation and disassembly work with the traction device, and the plow body is mostly not convenient for lifting and adjusting and horizontal position adjustment.

[0008] A further improvement is that the positioning mechanism comprises a fixing block fixed to the outer walls on both sides of the suspension rod and a positioning bolt with threads passing through the fixing block, and the top end of the positioning bolt is connected to the positioning block.

[0009] A further improvement is that threaded columns are symmetrically fixed to the front and rear outer walls of the support plate, threaded tubes are threadedly sleeved on the threaded columns, a positioning column is fixed to one end of the threaded tube away from the threaded column, and positioning grooves matching the positioning columns are opened on the front and rear inner walls of the tilling frame.

[0010] A further improvement is that a support frame covered on the outside of the threaded plate is fixed to the top of the support plate, and the top of the screw rod passes through the top of the support frame through a bearing and is fixedly connected to the turntable.

When it is necessary to disassemble, the two sets of spring latches 5 are pulled outward from the connecting seat 4 again and the connecting block 2 is taken out from the connecting seat 4.

[0034] When the height of the tillage plow 13 needs to be adjusted to perform tillage operations at different heights, the turntable is first rotated to drive the screw rod 8 to rotate, so that the threaded plate 9 threadedly sleeved on the screw rod 8 is lifted and lowered, and the hanging plate 10 and the bottom plate 11 are driven to lift and lower, and the bottom plate 11 then drives the hanging rod 12 and the tillage plow 13 to be adjusted to an appropriate height, so that the tillage operations at different soil heights can be achieved;

[0035] When the spacing between adjacent plows 13 needs to be adjusted to meet the plowing operations with different densities, first loosen the positioning bolt 17 to release the interference of the positioning block 18 with the base plate 11, and then slide the suspension rod 12 to drive the plows 13 to adjust the horizontal position until the spacing between adjacent plows 13 meets the plowing density requirement (the number of plows 13 can be appropriately adjusted by disassembling and assembling the plows 13), and after the adjustment is completed, tighten the positioning bolt 17 to drive the positioning block 18 to interfere with the base plate 11, thereby positioning the suspension rod 12.
