Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1-3 The utility model provides a sampler for feed detection, comprising:

[0023] An outer cylinder 1, a protective shell 2 is provided at the upper end of the outer cylinder 1, a conical head 3 is detachably connected to the lower end of the outer cylinder 1, a sampling column 4 is provided in the outer cylinder 1, a plurality of accommodating chambers 5 and a plurality of through holes 6 are provided in the sampling column 4, the accommodating chamber 5 is communicated with the through holes 6, the accommodating chamber 5 is communicated with the outside through the through holes 6, the sampling column 4 abuts against the inner wall of the outer cylinder 1, a rectangular connecting column 7 is fixedly connected to the sampling column 4, a driving mechanism is provided in the protective shell 2, the driving mechanism is transmission-connected with the rectangular connecting column 7, a plurality of first through holes 20 are provided on the outer cylinder 1, the size of the through holes 6 is smaller than the size of the first through holes 20, a handle 8 is fixedly connected to the outside of the protective shell 2, a vibration motor 9 is provided in the conical head 3, a controller 27 is fixedly connected to the protective shell 2, and the driving mechanism and the vibration motor 9 are electrically connected to the controller 27.

[0024] In the present device, the sampling column 4 is located in the outer cylinder 1, and the first through hole 20 on the outer cylinder 1 is convenient for the feed through hole. The feed sample enters the accommodating chamber 5 in the sampling column 4 through the through hole 6. The driving mechanism is used to drive the sampling column 4 to rotate. The conical head 3 facilitates the insertion of the present device into the feed, and the handle 8 facilitates the holding of the present device. Before inserting into the feed, the sampling column 4 is rotated by the driving mechanism so that the through hole 6 and the first through hole 20 are completely staggered to prevent the feed from entering during the insertion process. When sampling, the handle 8 is held to insert the present device into the feed. The conical head 3 makes the insertion of the present device more convenient. After entering to a predetermined depth, the sampling column 4 is driven to rotate by the driving mechanism so that the first through hole 20 and the first through hole 20 are completely staggered. The through holes 6 overlap, and the rotation angle of the sampling column 4 can be set by the driving mechanism, so as to facilitate the feed sample to enter the accommodating chamber 5. During the sampling process, the vibration motor 9 is started, and the vibration of the vibration motor 9 facilitates the feed to quickly enter the accommodating chamber 5. After the sampling is completed, the sampling column 4 is driven by the driving mechanism to rotate, so that the through hole 6 and the first through hole 20 are completely staggered to prevent the feed in the accommodating chamber 5 from mixing with the external feed. Then the device is pulled out from the feed, the conical head 3 is removed, the sampling column 4 is taken out from the outer cylinder 1, and the seeds in the accommodating chamber 5 are poured out to complete the sampling. It is more convenient to control the driving mechanism and the vibration motor 9 through the controller 27.

[0025] A further optimized solution is that the driving mechanism includes a driving motor 10, which is fixedly connected in the protective shell 2. A first gear 11 is fixedly connected to the output end of the driving motor 10, and a second gear 12 is rotatably connected in the protective shell 2. The first gear 11 is meshed with the second gear 12. A rectangular hole is opened on the second gear 12, and a rectangular connecting column 7 is inserted into the rectangular hole. The driving motor 10 is electrically connected to the controller 27.

[0026] The driving motor 10 drives the first gear 11 to rotate, and the first gear 11 drives the second gear 12 to rotate. Since the rectangular connecting column 7 is inserted into the rectangular hole, the second gear 12 can drive the rectangular connecting column 7 to rotate, so that the sampling column 4 can also rotate.

[0027] A further optimized solution is that a first connecting plate 13 is fixedly connected inside the protective shell 2, a first connecting hole is opened on the first connecting plate 13, a round tube 14 is rotatably connected inside the first connecting hole, the round tube 14 is rotatably connected inside the first connecting hole through a first bearing 15, the second gear 12 is fixedly connected to the round tube 14, and the round tube 14 and the second gear 12 are concentrically arranged.

[0028] The round tube 14 is rotatably connected to the first connecting plate 13 via the first bearing 15 , so that the second gear 12 is rotatably connected in the protective shell 2 .

[0029] A further optimized solution is that a second connecting plate 16 is fixedly connected inside the protective shell 2, a second through hole 17 is opened on the second connecting plate 16, the rectangular connecting column 7 passes through the second through hole 17, the outer cylinder 1 abuts on the second connecting plate 16, the second connecting plate 16 is rotatably connected to the first annular plate 18, the first annular plate 18 is rotatably connected to the second connecting plate 16 through a second bearing 19, and the first annular plate 18 abuts against the sampling column 4.

[0030] The first annular plate 18 and the second connecting plate 16 are rotatably connected via the second bearing 19 . When the sampling column 4 is placed into the outer cylinder 1 , the sampling column 4 will abut against the first annular plate 18 , which will make the sampling column 4 rotate more flexibly.

[0031] According to a further optimization scheme, a connecting tube 21 is fixedly connected to the conical head 3, a thread is provided on the outer edge of the connecting tube 21, a thread is provided on the inner edge of the outer tube 1 near one end of the conical head 3, and the connecting tube 21 is connected to the outer tube 1 through threads.

[0032] The connecting tube 21 is detachably connected to the outer cylinder 1 through threads, so that the conical head 3 is detachably connected to the outer cylinder 1 .

[0033] According to a further optimized solution, the connecting tube 21 is rotatably connected to a second annular plate 22 , a top plate 23 is fixedly connected to the second annular plate 22 , the second annular plate 22 is at the inner edge of the connecting tube 21 , and the top plate 23 abuts against the sampling column 4 .

[0034] The second annular plate 22 and the connecting tube 21 are rotatably connected via the third bearing 24. When the conical head 3 is installed in the outer tube 1, the top plate 23 will fit with the sampling column 4 to prevent the sampling column 4 from shaking in the outer tube 1, while also facilitating the rotation of the sampling column 4.

[0035] According to a further optimized solution, a plurality of threaded holes are provided on the protective shell 2 and the outer cylinder 1 , and screws 25 are connected to the threads in the threaded holes. The protective shell 2 and the outer cylinder 1 are connected by the screws 25 .

[0036] The screws 25 make the connection and disassembly of the protective shell 2 and the outer cylinder 1 more convenient.

[0037] According to a further optimized solution, an observation hole 26 is provided on the protective shell 2 .

[0038] The observation hole 26 facilitates observation of the rectangular connecting column 7 being inserted into the rectangular hole of the second gear 12 .

[0039] The method of using the device is as follows: before sampling, the sampling column 4 is driven to rotate by the driving motor 10, so that the through hole 6 and the first through hole 20 are completely staggered to prevent feed from entering during the insertion process. When sampling, the handle 8 is held and the device is inserted into the feed. The conical head 3 makes the insertion of the device more convenient. After entering to a predetermined depth, the first gear 11 is driven to rotate by the driving motor 10, and the first gear 11 drives the second gear 12 to rotate. Since the rectangular connecting column 7 is inserted into the rectangular hole, the second gear 12 can drive the rectangular connecting column 7 to rotate, so that the sampling column 4 can also rotate. The first through hole 20 is overlapped with the through hole 6, so that the feed sample can enter the accommodating chamber 5 through the first through hole 20. During the sampling process, the vibration motor 9 is started. The vibration of the vibration motor 9 facilitates the feed to quickly enter the accommodating chamber 5. After the sampling is completed, the sampling column 4 is driven by the driving motor 10 to rotate so that the through hole 6 and the first through hole 20 are completely staggered to prevent the feed in the accommodating chamber 5 from mixing with the external feed. Then the device is pulled out from the feed, the conical head 3 is unscrewed, the sampling column 4 is taken out from the outer tube 1, and the seeds in the accommodating chamber 5 are poured out to complete the sampling.
