[0028] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0029] like Figure 1-5 As shown, this utility model provides a portable in-cell shallow sampler, which mainly includes: a sampling tube 110, a flap 120, a sleeve 130, an insert plate 140, and a pull rod 150.

[0030] The sampling cylinder 110 has a cylindrical structure. The lower end of the sampling cylinder 110 has a grain inlet 111, and the lower side of the sampling cylinder 110 has a grain discharge port 112. The flap 120 is connected to the grain inlet 111 of the sampling cylinder 110 by a hinge 121. The flap 120 can be flipped upward to open the grain inlet 111 or flipped to close the grain inlet 111.

[0031] In this embodiment, the sampling tube 110 is made of stainless steel square tubing, with one end of the tube open as the grain inlet 111. Preferably, the stainless steel square tubing has a cross-sectional side length of 50mm and a length of 200mm.

[0032] The flap 120 is connected to the lower end of the sampling cylinder 110 via a 90° hinge. The two ends of the hinge 121 are connected to the side plates located on the left and right sides of the unloading port 112, and the hinge 121 is positioned close to the unloading port 112. When the sampler is inserted into the grain pile, the flap 120 is pushed upwards to a vertical position by the grain, and the grain enters the sampling cylinder 110 from the inlet 111. When the sampler reaches the required sampling depth, it is pulled upwards. Using the principle of the grain's own weight falling within the sampling cylinder 110, the flap 120 is pushed back to the inlet 111, sealing the inlet 111, allowing the desired sample to be retrieved. Due to the angle limitation of the flap 120, after flipping to the inlet 111, the flap 120 cannot continue to flip downwards.

[0033] As a further preferred embodiment, the length of the flap 120 from one end connected to the hinge 121 to the end away from the hinge 121 is greater than the length of the inner cross-section (in the same direction) of the sampling cylinder 110. The flap 120 will rest against the inner wall of the sampling cylinder 110 before being flipped downwards to its maximum angle to prevent excessive grain pressure from causing the hinge to fail.

[0034] In this embodiment, the hinge 121 is made of stainless steel.

[0035] The lower end of the sleeve 130 is fixedly connected to the upper end of the side of the sampling cylinder 110 where the unloading port 112 is provided, and the sleeve 130 is arranged along the axial direction of the sampling cylinder 110. The insert plate 140 is arranged on the side of the sampling cylinder 110 where the unloading port 112 is provided, that is, on the same side as the sleeve 130.

[0036] A pull rod 150 is disposed within the sleeve 130; the lower end of the pull rod 150 is fixedly connected to the insert plate 140, and the upper end extends above the sleeve 130. The pull rod 150 can reciprocate axially along the sleeve 130, causing the insert plate 140 to close or open the unloading port 112. Because the length of the pull rod 150 is greater than the length of the sleeve 130, when the insert plate 140 closes the unloading port 112, a section of the lower end of the pull rod 150 is exposed outside the sleeve 130, and the length of the exposed section is greater than or equal to the length of the insert plate, ensuring that the insert plate 140 can fully rise above the unloading port 112, thus fully opening the unloading port 112.

[0037] The sampling cylinder 110 has guide grooves 113 on both sides of the side with the unloading port 112, and the two sides of the insert plate are matched and set in the guide grooves 113. By setting the guide grooves 113, the position of the insert plate 140 can be limited, ensuring the stability of the sliding of the insert plate 140.

[0038] In this embodiment, right-angle pressure strips 160 are fixedly connected to the two side plates of the sampling cylinder 110 (stainless steel square tube). A gap is formed between the side plate of the right-angle pressure strip 160 and the side plate of the sampling cylinder 110 (which has a grain unloading port 112), and the gap serves as a guide groove 113. The right-angle pressure strip 160 is made of stainless steel.

[0039] A handle 151 is provided at the upper end of the pull rod 150. The handle 151 is located above the sleeve 130 to facilitate pulling the pull rod 150.

[0040] As a preferred embodiment, a crossbeam 131 is fixedly connected to the upper end of the sleeve 130, and the crossbeam 131 is arranged perpendicularly to the sleeve 130. The center of the crossbeam 131 is connected to the sleeve 130, and a through hole is opened on the crossbeam 131. The through hole is coaxially arranged with the sleeve 130 and communicates with the sleeve 130. The pull rod 150 extends through the through hole to the top of the crossbeam 131 and is connected to the handle 151.

[0041] In this embodiment, both the sleeve 130 and the crossbeam 131 are made of stainless steel tubing, and the tie rod 150 is made of cylindrical stainless steel strip. In one embodiment, the sleeve 130 is made of stainless steel tubing with a length of 1.25m and a thickness of 1mm.

[0042] The flap 120 is made of stainless steel, and its size matches the cross-sectional size of the sampling tube 110, ensuring that the flap 120 can rotate smoothly inside the sampling tube 110 without creating excessive gaps that could cause the grain to fall out.

[0043] As a further preferred option, anti-slip sleeves 170 are fitted at both ends of the crossbeam 131 to facilitate gripping.

[0044] The lower end of the sampling tube 110 has a pointed tip 114 for easy insertion into the grain pile.

[0045] In this embodiment, the side plates on the sampling cylinder 110 located on the left and right sides of the insertion plate 140 each have downwardly protruding pointed corner structures, which serve as the tip 114 for inserting the sampler into the grain pile. The pointed corner structures on the two side plates are symmetrically arranged.

[0046] The portable shallow sampler for warehouses provided by this utility model is lightweight and easy to carry. It can be operated by a single person and can flexibly collect samples from locations such as grain condition inspection platforms, corners, and walls within 1 meter in depth, making it easier to detect changes in shallow grain conditions and take timely measures to deal with them.

[0047] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
