Mouthful mutually stagger with the notch above outer tube, on the outer tube, one in two notch edges upwardly extended along outer axial tube
Bar sets the scraper of protrusion above oriented notch.Further, the tip of the outer tube is provided with tip, is provided with the outside of tip
Screw thread.
Further, the tail end of the outer tube and the tail end of inner tube are respectively arranged with a handle, the hand of the outer tube tail end
Handle length is more than the decreased food of inner tube tail end.
Further, a groove is offered by inner tube front end to inner tube tail end in said inner tube, set inside the groove
There are multiple dividing plates, the groove is isolated into the multiple dividing plate into multiple notches and the notch above the outer tube is mutually corresponding
Groove.
Further, said inner tube tail end is provided with spring holder, and the outer tube tail end corresponds to the position of spring holder
Place is provided with pin-and-hole, and the pin-and-hole offers at least individual in outer tube tail end circumference, relatively rotates said inner tube, can make positioning
Pin coordinates with the pin-and-hole grafting of outer tube tail end successively.
Beneficial effects of the present invention：The two-tube sampler suitable for large volume agricultural product of the present invention includes outer tube and setting
Inner tube in outer tube, cooperation is circumferentially rotated between the outer tube and inner tube；Said inner tube and outer tube are each along itself axial direction
Be installed with multiple grooves, the notch above said inner tube is mutually corresponding with the notch position above outer tube, relatively rotate outer tube with
Inner tube can make the notch above notch and outer tube above inner tube mutually stagger, and on the outer tube, two upward along outer axial tube
A scraper that protrusion above oriented notch is set in the notch edges of extension., can when spun outer tube by setting scraper
Scraper is cut down sample at the solid matter of periphery, and sample was collected in groove, so as to reach using two-tube sampler
The purpose being sampled to solid matter.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram for the two-tube sampler that the present invention is applied to large volume agricultural product；
Fig. 2 is the dimensional structure diagram for the two-tube sampler middle external tube that the present invention is applied to large volume agricultural product；
