SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the technical problem that the utility model provides a knife edge is polished conveniently, goes out the complete tubulose roughage sampler of filling real drill pipe inner chamber of appearance.

In order to achieve the above object, the utility model provides a tubulose roughage sampler, bore and can dismantle the cavity tubulose drilling rod that the connection sample bored, characterized by including the sample: the drill rod is characterized in that a cutter head section is arranged at the other end of the drill rod, a port of the cutter head section is a round-mouth-shaped cutter head, a cavity of the cutter head section is formed after the cavity of the drill rod is reduced in diameter, and a shell of the drill rod is gradually reduced in diameter after being expanded in diameter to form a shell of the cutter head section.

During the use, the sample drill presss from both sides tight connection lid, then buckles the connecting portion of connecting the lid into the drilling rod, drills into the bale with the drilling rod and takes a sample, and the forage that is cut off is filled in getting into the cavity of drilling rod. Drilling in the forward rotation mode, pulling out the forward rotation mode, detaching the drill rod, and poking out the grass sample by using a cylindrical long stick.

Preferably, the method comprises the following steps:

the inner diameter of the cavity of the drill rod is reduced by 2-4mm to form the cavity of the cutter head section, and the grass sample enters the inner cavity of the drill rod through the cutter head section and then provides a moderate expansion space, so that more grass samples can be conveniently filled into the cavity of the drill rod and the inner cavity of the complete drill rod is filled.

The inner diameter of the cavity of the drill rod is 29mm, the inner diameter of the cavity of the tool bit section is 26mm, and the sampling effect is better under the size.

The shell of the drill rod is expanded by 1-3mm and then gradually reduced in diameter to form the shell of the cutter head section, so that the drill rod can more easily drill into a bale.

Drilling rod one end pipe wall thickening after form connecting portion, connecting portion buckle connect one be used for connecting the connection lid that the sample bored, the thickening pipe wall increases support strength, the drive firmness is higher.

Connecting portion both sides open respectively and have a type of falling T groove, the connection lid include a size and connecting portion cavity assorted cylinder, the cylinder both sides be equipped with a arch respectively, the cylinder top be equipped with a connecting post, two archs of connection lid are embedded into two types of falling T grooves respectively and are carried out the buckle.

The lateral wall of the cylinder is provided with a through ventilation groove, so that a ventilation opening is formed when the grass sample is filled into the cavity, and the grass sample can conveniently enter the cavity.

The utility model provides a tubulose coarse fodder sampler, carry out undergauge or hole enlargement to drilling rod tool bit section inner chamber and outer wall, make the drilling rod bore into the bale more easily, the straw sample fills into the drilling rod cavity more, once sample realizes filling the effect of whole drilling rod cavities; the round-mouth-shaped tool bit is convenient to polish; in addition, independent research and development are realized, and compared with the mainstream products in the market, the product is imported, has low cost and is suitable for popularization and application.
