DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: See Figure 1-Figure 5 As shown, the utility model provides a rice batch sample sampling device, comprising an outer tube 1 and an inner tube 2, both of which are hollow tubular structures with pointed bottoms, wherein the inner tube 2 is movably arranged inside the outer tube 1, and the outer side wall of the inner tube 2 is arranged in contact with the inner side wall of the outer tube 1, and the inner tube 2 can rotate circumferentially and slide axially relative to the outer tube 1. Specifically, four outer wire slots 11 are axially opened on the side wall of the outer tube 1, and four inner wire slots 21 are correspondingly opened on the side wall of the inner tube 2. A conical bottom tube 211 is arranged at the bottom of each inner wire slot 21 inside the inner tube 2, and a sealing piece 25 is arranged above the uppermost inner wire slot 21 inside the inner tube 2. An inner discharge port 24 is opened on the side wall of the inner tube 2 and below the conical bottom tube 211. A feed opening 212 is opened at the bottom of the conical bottom tube 211. A feed opening 212 is connected to the inner discharge port 24. The feed opening 212 is composed of a straight tube 213 and a 90-degree elbow 214. An outer discharge port 14 is opened on the side wall of the outer tube 1, an outer tube handle 13 is arranged on the top of the outer wall of the outer tube 1, and an inner tube handle 23 is arranged on the top of the outer wall of the inner tube 2. It should be noted that when the outer slot hole 11 and the inner slot hole 21 are located at the same horizontal height, the outer feed port 14 and the inner discharge port 24 are staggered in horizontal height. According to this arrangement, when the inner tube 2 only rotates circumferentially relative to the outer tube 1, the outer slot hole 11 and the inner slot hole 21 can be adjusted to be in a connected open state or a dislocated blocked state. At this time, the outer feed port 14 and the inner discharge port 24 are staggered and cannot be discharged. This process facilitates sampling. When the inner tube 2 slides axially relative to the outer tube 1, that is, the inner discharge port 24 and the outer feed port 14 are connected by axially pulling the inner tube 2. At this time, the rice sample can be discharged in sequence through the discharge port 212 of the conical bottom tube 211, the discharge tube, the inner discharge port 24 and the outer feed port 14. The discharge process relies on gravity and does not require dumping. There are advantages of convenient discharge and no dead angle for discharge.

[0021] On the basis of the above-mentioned embodiment, a limiting slot 12 is provided on the side wall of the outer tube 1. The limiting slot 12 is an L-shaped structure and consists of a horizontal slot 121 and a vertical slot 122. A limiting rod 22 is fixedly provided on the outer side wall of the inner tube 2. The limiting rod 22 is arranged in the limiting slot 12. When the limiting rod 22 is located at the right end of the horizontal slot 121, the inner line slot 21 and the outer line slot 11 are in a connected state. When the limiting rod 22 is located at the left end of the horizontal slot 121, the inner line slot 21 and the outer line slot 11 are in a staggered state. When the limiting rod 22 is located at the upper end of the vertical slot 122, the outer feeding port 14 is in a connected state with the inner discharge port 24. Before inserting the rice pile, the inner tube 2 is first rotated by the inner tube handle 23 until the limit rod 22 is located at the left end of the horizontal slot hole 121. At this time, the outer line slot hole 11 is blocked by the side wall of the inner tube 2, and it is impossible to feed and sample. After the device is inserted to a predetermined depth, the inner tube 2 is rotated until the limit rod 22 is located at the right end of the horizontal slot hole 121. At this time, the outer line slot hole 11 and the inner line slot are in a connected and open state, and rice is fed and sampled. After the sampling is completed, the inner tube 2 is rotated back along the circumferential direction, and the outer tube handle 13 is used to take the rice. The device is placed roughly horizontally with the outer slot 11 facing upward, the inner tube 2 is rotated until the limit rod 22 is located at the right end of the horizontal slot 121, and some samples are taken out from each outer slot 11 and tested accordingly, and then the inner tube 2 is rotated until the limit rod 22 is located at the left end of the horizontal slot 121, the device is placed vertically above the rice pile, and the inner tube 2 is pulled upward until the limit rod 22 is located at the upper end of the vertical slot 122, and the rice in the inner tube 2 is discharged from the outer feeding port 14. In this embodiment, a downwardly inclined guide eaves (not shown in the figure) can be further provided on the outer side wall of the outer tube 1 and at the lower edge of the outer feeding port 14 to facilitate the rice discharged along the outer feeding port 14 to be guided outward.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
