Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-2 As shown, a grain sampling device includes a sampling tube 1, which includes an inner sampling tube 102 and an outer sampling tube 101 rotatably sleeved on the inner sampling tube 102. Both the inner sampling tube 102 and the outer sampling tube 101 have sampling ports 3 that communicate with their interiors. When the sampling ports 3 on the inner sampling tube 102 and the outer sampling tube 101 overlap, the grain sample enters the inner sampling tube 102. Thus, before inserting the grain, the sampling ports 3 on the inner sampling tube 102 and the outer sampling tube 101 can be staggered. After the sampling tube 1 is inserted to a specified depth, the sampling ports 3 on the inner sampling tube 102 and the outer sampling tube 101 are overlapped, which facilitates sampling of deep grain and prevents the grain from entering before the sampling ports 3 on the sampling tube 1 reach the specified depth. A conical tip 2 is fixedly installed at one end of the sampling inner tube 102 to facilitate the sampling tube 1 entering the grain to take samples.

[0021] The protective tube 4 is detachably installed on the sampling tube 1, and the protective tube 4 comprises a connecting tube 401 and a sleeve 402 fixedly sleeved on the outer periphery of the connecting tube 401. The inner diameter of the connecting tube 401 is the same as the outer diameter of the sampling inner tube 102, so that the connecting tube 401 is easily sleeved on the outer periphery of the sampling inner tube 102. The inner diameter of the sleeve 402 is the same as the outer diameter of the sampling outer tube 101, so that the sleeve 402 is easily sleeved on the outer periphery of the sampling outer tube 101. The outer periphery of the sleeve 402 is symmetrically and fixedly provided with a handle 9. When the protective tube 4 is installed on one side of the sampling tube 1 close to the conical sharp head 2, the sleeve 402 is threadedly connected with the sampling outer tube 101, and the protective tube 4 covers the conical sharp head 2 in the interior of the protective tube 4, so that the conical sharp head 2 is prevented from easily injuring people or damaging objects when the sampling tube 1 is not used. The sleeve 402 is internally provided with an internal thread 10, and the outer periphery of the sampling outer tube 101 is externally provided with an external thread 11. The sampling outer tube 101 is installed by matching the external thread 11 on the outer periphery of the sampling outer tube 101 with the internal thread 10 in the sleeve 402, so that the detachable installation of the protective tube 4 and the sampling outer tube 101 is realized. When the protective tube 4 is installed on the side of the sampling tube 1 away from the conical sharp head 2, the connecting tube 401 is detachably connected with the sampling inner tube 102 through the bolt 5, so as to increase the length of the sampling tube 1 and facilitate the operator to rotate the sampling inner tube 102 through the protective tube 4. The connecting tube 401 and the sampling inner tube 102 are both provided with threaded holes through which the bolt 5 is penetrated and threadedly connected with the threaded holes. Thus, the detachable installation of the protective tube 4 and the sampling inner tube 102 is realized.

[0022] The sampling inner tube 102 is symmetrically and fixedly provided with a guide block 12 on the side away from the conical sharp head 2. The connecting tube 401 is symmetrically provided with a guide groove 13 slidably matched with the guide block 12. When the guide block 12 is completely entered into the guide groove 13, the threaded holes on the connecting tube 401 and the sampling inner tube 102 are quickly aligned, the bolt 5 is quickly penetrated into the threaded holes on the connecting tube 401 and the sampling inner tube 102, and the connecting efficiency of the connecting tube 401 and the sampling inner tube 102 is improved.

[0023] The bolt 5 is fixedly provided with an indicating needle 6 on the outer periphery. The sampling outer tube 101 is symmetrically and fixedly provided with a handle 7. The handle 7 is provided with an indicating groove 8 matched with the indicating needle 6. When the sampling inner tube 102 is connected with the protective tube 4 through the bolt 5, the direction of the indicating needle 6 is consistent with the axial extension direction of the sampling tube 1. Thus, when the sampling ports 3 on the sampling inner tube 102 and the sampling outer tube 101 are completely overlapped or completely staggered, the indicating needle 6 can respectively point to the corresponding indicating groove 8.

[0024] Working principle:

[0025] In use, the sampling tube 1 is inserted into the grain by holding the handle 9 and the handle 7, and when the sampling tube 1 reaches the sampling depth, the sampling outer tube 101 is kept stationary, and then the protective tube 4 is rotated by holding the handle 9, and the protective tube 4 rotates the sampling inner tube 102, and when the protective tube 4 drives the indicator 6 to point to one of the indicator slots 8, it means that the sampling port 3 on the sampling inner tube 102 is completely aligned with the sampling port 3 on the sampling outer tube 101, so that the grain enters the sampling inner tube 102. If the sampling tube 1 is inserted horizontally into the grain, the sampling tube 1 can be shaken at this time, and the grain sample can flow out of the sampling inner tube 102 and the protective tube 4 into an external sample container.

[0026] If the sampling tube 1 is inserted vertically into the grain, when the grain enters the sampling inner tube 102, the protective tube 4 is continuously rotated, and when the protective tube 4 drives the indicator 6 to point to the other indicator slot 8, it means that the sampling port 3 on the sampling inner tube 102 is completely misaligned with the sampling port 3 on the sampling outer tube 101, and then the sampling tube 1 is taken out of the grain to prevent the grain sample from spilling out of the sampling inner tube 102. Finally, after the sampling tube 1 is taken out of the grain sample, the sampling tube 1 is inverted, and the grain sample flows out of the sampling inner tube 102 and the protective tube 4 into an external sample container.

[0027] When the sampling tube 1 is not in use, the bolt 5 is screwed, the connecting tube 401 of the protective tube 4 is detached from the sampling inner tube 102, and then the sleeve 402 on the protective tube 4 is sleeved on the sampling outer tube 101, and the external threads 11 on the sampling outer tube 101 are connected with the internal threads 10 in the sleeve 402, so that the conical sharp head 2 is covered inside the protective tube 4, and the conical sharp head 2 is prevented from injuring people or damaging objects.

[0028] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
