Description

Technical Field

[0001] The utility model relates to a sampler, in particular to a layered sampler for grain detection. Background Technique

[0002] When storing grains in a warehouse and during the storage process, it is necessary to sample and detect each batch of grains. Currently, the common grain sampler is generally an inserted tube sampler. Each time it is used, it can only sample grains at a single depth, with relatively large limitations.

[0003] After retrieval, the patent with the publication number CN217237364U discloses a layered sampler for grain detection. When in use, the staff can rotate the round tube to make the sampling groove communicate and align with the sampling port, then insert the device into the grains. After insertion, rotate the round tube and the cylinder as a whole, so that the grains enter the sampling groove. Finally, the staff can rotate the round tube again to seal the sampling groove with its inner wall, thus completing the layered sampling of the grains.

[0004] In the above scheme, although it can perform layered sampling of grains during use, when the sampling depth is relatively deep, it is quite laborious to insert the sampler into the grain pile or pull it out from the grain pile, which needs to be improved. Content of the Utility Model

[0005] The purpose of the utility model is to provide a layered sampler for grain detection to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] A layered sampler for grain detection includes a cylinder with a conical bottom end. A plurality of opening grooves are arranged through the outer wall of the cylinder along its length direction. The top end of the cylinder is open, and a conduit is detachably and fixedly connected to the top end of the cylinder. An inner rod is movably inserted through the conduit. A limiting ring is fixedly connected to the outer wall of the inner rod below the conduit. The top end of the inner rod passes through the conduit and is detachably and fixedly connected to a limiting disk. A plurality of holding rods are fixedly connected to the outer peripheral wall of the limiting disk. A plurality of sampling cylinders are arranged in the cylinder from top to bottom. The sampling cylinders correspond to the opening grooves one by one, and sampling ports are arranged through the corresponding positions of the outer wall of the sampling cylinder and the opening grooves. Adjacent sampling cylinders are fixedly connected by connecting rods. The bottom end of the inner rod is fixedly connected to the top of the uppermost sampling cylinder. A sliding sleeve is slidably sleeved on the outer wall of the conduit.

[0008] As a further scheme of the utility model: A connecting seat is fixedly sleeved at the top end of the outer wall of the cylinder. A lower connecting ring is fixedly sleeved at the bottom end of the outer wall of the conduit. The lower connecting ring is fixedly connected to the connecting seat by bolts.

[0009] As a further solution of the utility model: a upper connecting ring is fixedly sleeved at the top end of the outer wall of the conduit. An arc-shaped groove is formed at the top of the upper connecting ring, and a first positioning hole and a second positioning hole communicating with the arc-shaped groove are respectively formed at both ends of the arc-shaped groove at the top of the upper connecting ring. A hand-tightening bolt is inserted through the threaded hole at the top of the limiting disc. The threaded end of the hand-tightening bolt is located in the arc-shaped groove, and both the first positioning hole and the second positioning hole are adapted to the hand-tightening bolt. When the hand-tightening bolt is aligned with the first positioning hole in the vertical direction, the sampling port is aligned with the corresponding opening groove.

[0010] As a further solution of the utility model: a rectangular block is fixedly connected to the top end of the inner rod. The limiting disc is sleeved on the rectangular block through a square groove adapted to the rectangular block. A screw is inserted through the top of the limiting disc, and a threaded hole adapted to the screw is formed at the top of the rectangular block.

[0011] As a still further solution of the utility model: a plurality of guide plates are fixedly connected to the outer peripheral wall of the cylinder body.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] When the utility model is in use, after inserting the bottom end of the cylinder body into the grain pile, quickly slide the sliding sleeve downward on the conduit so that the bottom end of the sliding sleeve impacts the lower connecting ring, then a downward impact force can be applied to the cylinder body, thereby enabling the cylinder body to move downward by a certain distance in the grain pile. By repeating the operation, the cylinder body can be easily inserted to the required depth. Similarly, by simply using the top end of the sliding sleeve to impact the upper connecting ring, the cylinder body can be relatively easily pulled out of the grain pile.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 5 , in the embodiment of the present invention, a layered sampler for grain detection includes a cylinder body 1 with a conical bottom end. A plurality of opening grooves 3 are arranged through the outer wall of the cylinder body 1 along its length direction. The top end of the cylinder body 1 is open, and a conduit 5 is detachably and fixedly connected to the top end of the cylinder body 1. An inner rod 11 is movably inserted through the conduit 5. A limiting ring 12 is fixedly connected to the outer wall of the inner rod 11 below the conduit 5. The top end of the inner rod 11 passes through the conduit 5 and is detachably and fixedly connected to a limiting disc 17. A plurality of grip rods 19 are fixedly connected to the outer peripheral wall of the limiting disc 17. A plurality of sampling cylinders 13 are arranged in the cylinder body 1 from top to bottom. The sampling cylinders 13 correspond to the opening grooves 3 one by one, and a sampling port 14 is arranged through the corresponding position of the outer wall of the sampling cylinder 13 and the opening groove 3. Adjacent sampling cylinders 13 are fixedly connected by a connecting rod 15. The bottom end of the inner rod 11 is fixedly connected to the top of the uppermost sampling cylinder 13. A sliding sleeve 21 is slidably sleeved on the outer wall of the conduit 5. Upper connecting rings 7 and lower connecting rings 6 are respectively fixedly sleeved at both ends of the outer wall of the conduit 5.

[0022] By adopting the above solution, when in use, after inserting the bottom end of the cylinder body 1 into the grain pile, quickly slide the sliding sleeve 21 downward on the conduit 5 so that the bottom end of the sliding sleeve 21 impacts the lower connecting ring 6, then a downward impact force can be applied to the cylinder body 1, thereby enabling the cylinder body 1 to move downward a certain distance in the grain pile 1. By repeating the operation, the cylinder body 1 can be easily inserted to the required depth. Similarly, by simply using the top end of the sliding sleeve 21 to impact the upper connecting ring 7, the cylinder body 1 can be relatively easily pulled out from the grain pile;

[0023] After the cylinder body 1 is inserted to the required depth in the grain pile, rotate the limit disc 17 and the inner rod 11 through the grip rod 19 so that the sampling cylinder 13 rotates until the sampling port 14 aligns with the opening groove 3. Then the grains in the grain pile can fall into the corresponding sampling cylinder 13. After that, rotate the sampling cylinder 13 again so that the sampling port 14 and the opening groove 3 are staggered. In this way, when the cylinder body 1 is pulled out of the grain pile, it can be avoided that the grains spill out of the sampling cylinder 13. When it is necessary to pour out the grains in the sampling cylinder 13, just rotate the sampling cylinder 13 again until the sampling port 14 aligns with the opening groove 3. The operation is simple and convenient.

[0024] Specifically combined with Figure 1 and Figure 2 , in an embodiment of the present invention, a connecting seat 4 is fixedly sleeved at the top end of the outer wall of the cylinder body 1, and the lower connecting ring 6 is fixedly connected to the connecting seat 4 by bolts, so as to facilitate the disassembly and assembly between the cylinder body 2 and the conduit 5.

[0025] Specifically combined with Figure 4 and Figure 5 , in an embodiment of the present invention, an arc-shaped groove 8 is formed at the top of the upper connecting ring 7, and first positioning holes 9 and second positioning holes 10 communicating with the arc-shaped groove 8 are respectively formed at both ends of the top of the upper connecting ring 7. The top of the limit disc 17 is provided with a hand-tightening bolt 20 through a threaded hole in a matching manner. The threaded end of the hand-tightening bolt 20 is located in the arc-shaped groove 8, and both the first positioning hole 9 and the second positioning hole 10 are adapted to the hand-tightening bolt 20. When the hand-tightening bolt 20 is aligned with the first positioning hole 9 in the vertical direction, the sampling port 14 aligns with the corresponding opening groove 3.

[0026] Through the cooperation of the hand-tightening bolt 20 with the arc-shaped groove 8, the first positioning hole 9 and the second positioning hole 10, it is convenient to position the sampling cylinder 13 inside the cylinder body 1. By screwing the hand-tightening bolt 20 into the first positioning hole 9, the sampling cylinder 13 can be locked inside the cylinder body 1, so that the sampling port 14 always aligns with the opening groove 3. By screwing the hand-tightening bolt 20 into the second positioning hole 10, the sampling cylinder 13 can be locked inside the cylinder body 1, so that the sampling port 14 always staggers from the opening groove 3, thereby avoiding relative rotation between the cylinder body 1 and the sampling cylinder 13 due to misoperation.

[0027] Specifically combined with Figure 4 , in an embodiment of the present invention, a rectangular block 16 is fixedly connected to the top end of the inner rod 11. The limit disc 17 is sleeved on the rectangular block 16 through a square groove adapted to the rectangular block 16. A screw 18 is inserted through the top of the limit disc 17, and a threaded hole adapted to the screw 18 is formed at the top of the rectangular block 16, so as to facilitate the disassembly and assembly between the inner rod 11 and the limit disc 17.

[0028] Specifically combined with Figure 1, in an embodiment of the present utility model, a plurality of guide plates 2 are fixedly connected to the outer peripheral wall of the cylinder body 1. By means of the arrangement of the guide plates 2, after the cylinder body 1 is inserted into the grain pile, the cylinder body 1 can be prevented from rotating in the grain pile.

[0029] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
