As one embodiment, as shown in fig. 8, the soil sampling device mounting structure is a mounting hole 110 provided on the drill bit for inserting a connecting column 109 on a barrel of the soil sampling device, and the mounting hole 110 into which the connecting column 109 is inserted is then inserted into a pin hole 112 formed on the connecting column 109 through a pin 111 to achieve mounting.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
