3.3.3 The heat treatment hardness of the sprocket ring is 40~50HRC. 3.3.4 Plow body
3.3.4.1 There should be a gap of 0.5~1mm between the connecting plate at the lower end of the plow post and the plow handle to ensure that the plow zinc can be disassembled and assembled freely. 3.3.4.2 After the plow post and plow blade are assembled, the angular deviation of the center line should be within the range of ±2°. 3.3.5 Frame
3.3.5.1 The planes on the frame should be in the same plane, with a flatness tolerance of 5mm. The beams should be parallel, with a parallelism tolerance of 3mm. 3.3.5.2
3.3.5.3 The traction point connecting plate and the ground wheel support should be perpendicular to the frame respectively, with a verticality tolerance of 2mm. 3.4 Technical requirements for assembly
Each moving part and component must operate flexibly and smoothly without collision and jamming. The adjustment mechanism should ensure the adjustment range and the adjustment should be flexible. The connectors and fasteners must be firmly and reliably connected. The height difference between the horizontal base surface of each plow tip and the bottom plane of the frame is ±5mm. The horizontal projections of each plow blade should be on the same straight line, and the mutual deviation should not exceed 10mm.

The surface of the whole machine after painting shall be flat and smooth, and no obvious indentation or damage is allowed. 3.6.4
Inspection rules
1 Factory inspection
JB/T7135.1→93
Each submersible tillage plough must be accompanied by the manufacturer's product quality certificate before it can be shipped. Before leaving the factory, each submersible tillage plough should be subjected to an idle running test for no less than 20 minutes and should meet the following requirements: smooth operation without collision or abnormal sound; flexible adjustment mechanism;
Connectors and fasteners must not fall off or loosen; and should comply with the provisions of Articles 3.4.5, 3.5 and 3.6.4 of this standard. Type inspection
Type inspection should be carried out in any of the following circumstances: trial production and identification of new products or old products transferred to other factories; after formal production, when there are major changes in structure, materials, and processes that may affect product performance; during normal production, type inspection should be carried out every 3 years; when the product is resumed after a production stoppage of more than 2 years; when there is a major difference between the factory inspection results and the last type inspection; when the national quality supervision agency proposes a type inspection requirement. The batch for type inspection is 1 to 8 units, and 2 units are randomly selected. The sampling plan and judgment rules are shown in the following table. Item
