AI Technical Summary
In existing grain sampling devices, the connection between the sampling probe and the extension steel pipe is unstable, and the probe is easily lost due to increased friction, which affects its use.
The design employs a limiting block, a first spring, a locking block, and a guide groove to ensure a more stable connection between the grain sampling probe and the sampling extension tube. By pressing the limiting block with the spring, the limiting block further restricts the connection as the depth increases, preventing it from falling off.
This makes the connection between the grain sampling probe and the sampling extension tube more stable, avoids probe loss, and improves the reliability of the sampling device.
