Specifically, the diameter of the cone is not smaller than the inner diameter of the lower opening end.

Specifically, the sleeve, the spring, the push rod and the sampler are made of stainless steel.

The utility model provides a single-point powder sampling device compares with prior art and has following advantage:

1. when sampling, the sampler is pushed out by holding the push rod by hand, the powder enters the groove of the sampler, and the sampler returns to the initial position through the rebound force of the spring, thus completing sampling. The sample taken out can be directly transferred into the sample bottle, so that material adsorption caused by secondary transfer is avoided.

2. The sampler surface is smooth, no dead angle, compares traditional square sampler and easily washs.

Therefore, the utility model provides a utility model, quick, accurate, easy clear powder sampling device.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are only some embodiments, but not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example one

Referring to fig. 1, there is shown a single-point powder sampling device of the present invention, comprising: the upper end and the lower end of the sleeve 2 are provided with openings, and the inner diameter of an upper opening end 21 of the sleeve 2 is larger than that of a lower opening end 22; a spring 3 located within the upper open end 21, the spring 3 being unable to displace downwardly within the sleeve 2 to the lower open end 22; the push rod 1 penetrates through the spring 3 from top to bottom, the push rod 1 is movably inserted into the sleeve 2, the T-shaped hand-holding component 11 at the upper end of the push rod can be clamped outside the spring 3, and the push rod 1 can move along the axial direction of the push rod 1 by compressing the spring 3; with the thin pole 12 of push rod lower extreme can dismantle sampler 4 of being connected, sampler 4 comprises connector 41, connecting rod 42 and the appearance head 43 of inserting of coaxial setting in proper order, and the appearance head 43 of inserting is located the outside of lower open end 22 and can plugs up lower open end 22, and connector 41 and connecting rod 42 are located sleeve pipe 2 to enclose recess 44 in sleeve pipe 2 and be used for holding the powder of waiting to take a sample.

Example two

The detailed procedure for the whole sampling is as follows:

firstly, the operator inserts the single-point powder sampling device into the powder layer in an initial state (as shown in fig. 1 a) in which the connector 41 and the connecting rod 42 are in the casing 2 and the sample inserting head 43 blocks the lower opening end 22;

by the operator exerting a pushing force on the push rod 1, the spring 3 is compressed, the sampler 4 is pushed completely out of the sleeve 2 (fig. 1 b), the powder enters the groove 44;
