Embodiment 1

[0031] Such as Figure 1-6 As shown, the purpose of this embodiment is to provide a sampling head, and the sampling head has an integrated structure. figure 1 A schematic diagram of the three-dimensional structure of the sampling head in this embodiment is disclosed. The sample head is made of plastic material or metal material. In some embodiments, a split structure may also be used. The sample head has a body 1 . A cavity 2 , a material outlet 3 and at least one material inlet 4 are arranged on the body 1 . A first external thread 8 is provided on the outer peripheral wall of the upper part of the body 1 . The arrangement of the first external thread 8 facilitates the connection of the sampling head with the feed pipe of the sampling device. In some embodiments, the outlet port 3 of the sampling head is fixedly and through-connected with the feeding pipe of the sampling device by welding. In this embodiment, the cavity 2 is axially disposed in the body 1 and the cavity...

Embodiment 2

[0035] Such as Figure 1-6As shown, the purpose of this embodiment is to provide a sampling head, which has a cylindrical tubular structure as a whole. figure 1 A schematic diagram of the three-dimensional structure of the sampling head in this embodiment is disclosed. The sample head has an integrated structure. The cutting head is made of plastic material or metal material. In some embodiments, a split structure may also be used. The sample head has a body 1 . A cavity 2 , a material outlet 3 and at least one material inlet 4 are arranged on the body 1 . A first external thread 8 is provided on the outer peripheral wall of the upper part of the body 1 . The arrangement of the first external thread 8 facilitates the connection of the sampling head with the feed pipe of the sampling device. In some embodiments, the sampling head can be fixedly and through-connected with the feed pipe of the sampling device by welding. In this embodiment, the cavity 2 is axially disposed...

Embodiment 3

[0039] In this embodiment, the difference from embodiment 1 or embodiment 2 is that concave grooves are evenly and spacedly provided on the peripheral wall surface of the cone head 6 .

Abstract

The invention relates to a sampling head which comprises a body, the body is provided with a discharge port, an axially arranged cavity and at least one feed port, and the feed port is located at the lower part of the body and is communicated with the cavity; the discharge port is located in the upper portion of the body and communicated with the cavity, at least one air inlet is formed in the circumferential outer wall of the top of the body, and the air inlet is connected with an air inlet channel in the body in a communicated mode. The air inlet channel is communicated with the axial cavity. The sampling head is relatively high in working efficiency and does not generate a material blocking phenomenon.

Description

technical field [0001] The invention relates to the technical field of sampling testing equipment, in particular to a sampling head. Background technique [0002] Most of the grain samplers in the prior art are single-layer tube structures and the sampling heads of the grain samplers are mostly single-sided openings, double-sided openings, and bottom openings. During the use of the sampler or the sampler head in the prior art, the phenomenon of material blockage is prone to occur, which affects the operation efficiency of the sampler. In particular, in the process of grain procurement, since most of the purchased grains contain relatively large amounts of water, material blocking is more likely to occur during the process of grain sampling, which affects the efficiency of sampling. In order to overcome the occurrence of the above-mentioned material blocking phenomenon, the prior art often solves the above-mentioned technical problems by blowing back the grain sampler with a...
