Background

In the powder metallurgy industry, because material particles are fine and have strong floatability and surface activity, when the characteristics of powder materials are detected, the uniformity and representativeness of detection data are ensured necessarily. The powder materials are absolutely uniform and difficult to achieve, and even a large-scale mixing device (such as a double-helix conical mixer, a horizontal ribbon mixer and the like) cannot be guaranteed. Therefore, in a large batch, a small amount of materials are selected, the timeliness, the position property and the like of the selected materials are also guaranteed, and a plurality of common samplers are made of metal materials, the top ends of the samplers are conical, so that the risk of introducing metal foreign matters and the risk of puncturing packaging auxiliary materials are caused.

Patent No. 201922226563.3 discloses a powder sampler, establish the sleeve pipe outside the hollow tube including hollow tube and movable sleeve, set up the first feed inlet of arranging from top to bottom on the hollow tube, set up the second feed inlet that sets up with first feed inlet one-to-one on the sleeve pipe, a locating hole has been seted up on the sleeve pipe, be equipped with the locating piece that a protrusion locating hole set up on the hollow tube, the locating hole includes first vertical section hole, vertical section hole of second and horizontal segment hole, first vertical section hole and sleeve pipe top opening are linked together, first vertical section hole and the vertical section hole of second are connected through obtuse angle turning section, vertical section hole of second and horizontal segment hole are connected through right angle turning section. The patent states that the positioning block is used for clamping the sleeve outside the hollow pipe, and if the positioning block slides out of an opening at the top end of the sleeve, the sleeve has the risk of sliding off the hollow pipe, so that powder materials are poured and scattered. And secondly, the sleeve pipe and the sampling inner cylinder do not form clearance fit, so that the nesting, the plugging and the rotation are not convenient.

In the powder sampler disclosed in patent No. 202021161732.6, the sampler includes an inner tube and an outer tube sleeved on the inner tube. The inner tube is equipped with three sampling chamber including being cylindric interior body, and interior introduction port has all been seted up to every sampling chamber, and three interior introduction port is the sharp setting. One end of the inner tube body is provided with a rotating rod, and the rotating rod is provided with an upper end opening communicated with a sampling chamber closest to the rotating rod. One end of the inner tube body, which is far away from the rotating rod, is provided with inner sample outlets which are staggered with the straight lines of the three inner sample inlets, and the inner sample outlets are communicated with the sampling chambers which are closest to the inner sample outlets. The outer tube comprises an outer tube body, the outer tube body is provided with outer sample inlets in one-to-one correspondence with the three inner sample inlets and outer sample outlets in correspondence with the inner sample outlets, and the outer sample outlets and the three outer sample inlets are arranged in a straight line. In the patent, one end of the inner tube body, which is far away from the rotating rod, extends along the direction far away from the rotating rod to form a conical part, the conical head part of the conical part is made of solid metal, and the risk of introducing metal foreign matters and puncturing auxiliary materials of the package exists.

In addition in the powder sampler that 201721823940.6 discloses, its technical scheme main points are including one end is sealed, one end open-ended outer sampling pipe, and one end is sealed, one end open-ended interior sampling pipe, interior sampling pipe is pegged graft in outer sampling pipe, a plurality of sample grooves have all been seted up on the outer wall of outer sampling pipe and interior sampling pipe, the sample groove sets up along the axis direction of interior sampling pipe, can open or seal the sample groove when interior sampling pipe and outer sampling pipe rotate relatively. The effective area of the powder material entering and exiting the inner cylinder is slightly smaller in the technical scheme; the inner sampling tube and the outer sampling tube do not form clearance fit, and a complex structure is required to be adopted, so that the inner sampling tube and the outer sampling tube can be inserted, pulled out and rotated; the closed ends of the inner sampling tube and the outer sampling tube are conical, so that the auxiliary material in the package can be punctured.

In view of this, further optimization and improvement of the sampler for the powder material are required.

Disclosure of Invention

The utility model discloses a solve the not enough of above-mentioned prior art existence, and propose one kind and optimize the improvement on current common sampler basis, get rid of the worry of introducing the metallic foreign matter and can stop the powder material sampler of the risk that sampler toper top punctures the packing and assists the material.

The utility model discloses a realize through following technical scheme:

the powder material sampler comprises an inner sampling cylinder and an outer sampling cylinder; one end of the sampling inner cylinder is sealed, the other end of the sampling inner cylinder is opened, and a sampling hole close to the sealed end is formed in the cylinder wall; the sampling hole does not exceed 1/2 of the height of the sampling inner cylinder; the outer sampling barrel is of a sleeve structure, the length of the inner sampling barrel is more than 2.2 times that of the outer sampling barrel, and the outer sampling barrel is sleeved with the outer wall of the inner sampling barrel and is in clearance fit with the inner sampling barrel.
