Abstract
Disclosed is a sampling head which can collect lump materials. A sampling rod connection flange is connected successively with a sampling rod, a diversion-cone and an inner spiral raiser coaxial. An axial direction coaxial of the inner spiral raiser is provided with a sampling helical blade which shows a big top and small bottom in general. The top end tail shrinks properly and the bottom end becomes narrow. A formation bus of a helicoidal surface of the sampling helical blade maintains an acute angle with an axis, forming an inner concave spiral groove. When sampling, the inner spiral raiser enters a material layer vertically, and stops rotating at the set depth. The material sample to be collected is already inside the inner concave spiral groove, the inner spiral raiser lifts vertically taking the collected sample outside the material layer.
Description
Technical field
The utility model relates to the sampling apparatus that a kind of material is gathered, and especially can gather the sampling head of lump material.
Background technology
At present, mainly to construct be by the sampling urceolus and the inside spin lifter is coaxial is formed by connecting to known sampling head.During sampling, reverse rotation or non-rotary sampling urceolus bore down with the inside spin device that is rotated in the forward is synchronously vertical, arrive predetermined depth post-sampling urceolus and the synchronous limit reverse rotation limit vertical-lift of inside spin lifter or do not rotate be lifted out synchronously material bed, sampling head moves to the emptying point with running gear, and the sampling urceolus is rotated in the forward or does not rotate the reverse rotation of inside spin lifter adopting material is thrown away from the below.This sample mode is better for the sample effect of small particles material, can occur that material is adopted to be advanced or adopt the phenomenon of blocking in the helical duct of material by force though adopt lump material, and sampling head bores resistance down and bores difficulty greatly down simultaneously.
Summary of the invention
Adopt the deficiency of lump material difficulty and material landing in order to overcome existing sampling head, the utility model provides a kind of sampling head, and this sampling head can be sampled to lump material, has solved the problem of adopting to advance block material, getting stuck simultaneously.
The technical scheme that its technical matters that solves the utility model adopts is: cancellation sampling urceolus, keep the inside spin lifter and the helical blade of inside spin lifter is adjusted, the helicoid formation bus of helical blade and the right-angle relationship of axis are adjusted into acute angle relation, form an indent helicla flute, its lower end becomes cone tip shape, and thief rod lower end (with inside spin lifter junction) establishes deflection cone.During sampling inside spin lifter clockwise direction rotation as wood screw like a cork vertically " brill " go into material bed, lump material is pushed to former material bed by sampling head through thief rod lower end deflection cone, the arrival predetermined depth is stopped the rotation, the material increment of required collection this moment has been in the indent helicla flute, the vertical-lift of inside spin lifter is with the material increment carry-over bed of material of being gathered, during the carry-over bed of material, upper materials is around thief rod lower end deflection cone is pushed to, can not squeeze out adopting material, move to the emptying point with running gear afterwards, the reverse rotation of inside spin lifter throws away adopting material from the below, finish the collection operation of lump material.
The beneficial effects of the utility model are, can not produce and get stuck, adopted not landing of material when gather lump material, do not destroy the lump material granularity, and sampling head device only adopts sampling inside spin lifter, and is simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is an outside drawing of the present utility model.
1. thief rod joint flanges among the figure, 2. thief rod, 3. inside spin lifter, 4. sampling helical blade, 5. deflection cone.
Embodiment
In the drawings, thief rod joint flange 1 and thief rod 2, deflection cone 5, inside spin lifter 3 are coaxial to be linked in sequence successively, at the axially coaxial sampling helical blade 4 that is distributed with of inside spin lifter 3, sampling helical blade 4 integral body are up big and down small shape, the top afterbody suitably shrinks the lower end and comes to a point gradually, the helicoid of sampling helical blade 4 forms bus and axis keeps acute angle relation, forms an indent helicla flute, and deflection cone 5 is located at thief rod 2 lower ends (with inside spin lifter 3 junctions).
Claims (3)
1. sampling head, the thief rod joint flange with thief rod, deflection cone, the inside spin lifter is coaxial is linked in sequence successively, at the axial coaxial sampling helical blade that is distributed with of inside spin lifter, it is characterized in that: the helicoid of sampling helical blade forms bus and axis keeps acute angle relation, forms an indent helicla flute.
2. sampling head according to claim 1 is characterized in that: the sampling helical blade is whole to be up big and down small shape, and the top afterbody suitably shrinks the lower end and comes to a point gradually.
3. sampling head according to claim 1 is characterized in that: in thief rod lower end and inside spin lifter junction deflection cone is set.
