However, the existing testing method is to directly take samples from the feed by hand. Sampling the bottom layer of feed is time-consuming and laborious. Furthermore, the sample storage container is fixedly connected to the sampling device and cannot be replaced, which results in sample residue remaining in the sample storage container, leading to inaccurate test results. Utility Model Content

[0004] This invention addresses the problems in the prior art where bottom feed sampling is difficult and the inability to replace sample storage containers leads to sample residue and inaccurate test results. It provides a single-arm rotary feed sampling device.

[0022] Furthermore, multiple sample containers are provided for storing different samples.

[0023] Furthermore, a rotating block is formed on the side of the drive shaft away from the sample container, and a positioning pin is provided on the rotating block;

[0024] The end cap has an outwardly extending flange on the side facing the sampler, and a fixing block is provided on the inner side of the extending flange. The fixing block has a pin hole that cooperates with the positioning pin.

[0057] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0058] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0059] This embodiment provides a single-arm rotary feed sampling device, referring to... Figure 1 and Figure 2 As shown, it includes a drill bit 1, a drill motor 2, a sampler 3, a sample container 4, a drive shaft 5, an end cap 6, a deflection motor 7, and a battery 8. The drill motor 2 is installed inside the sampler 3, and its output end is fixedly connected to the drill bit 1. The drill bit 1 is installed at one end of the sampler 3, and the end cap 6 is installed at the other end of the sampler 3, away from the drill bit 1. The sample container 4 is also installed inside the sampler 3, and one end of the sample container 4 is connected to the drive shaft 5. The drive shaft 5 passes through the end cap 6 and is fixedly connected to the output end of the deflection motor 7. The battery 8 is installed on the top of the sampler 3 to provide power to the drill motor 2 and the deflection motor 7.

[0060] Combination Figure 3 and Figure 4 It can be seen that the main structure of the sampler 3 is cylindrical, with a rotating shaft hole 31 at one end and a partition 32 inside, which divides the interior of the sampler 3 into a motor chamber 33 and a sampling chamber 34. A drill motor 2 is installed in the motor chamber 33. The output shaft of the drill motor 2 passes through the rotating shaft hole 31 and is fixedly connected to the drill bit 1. A spiral discharge groove 11 is machined on the drill bit 1. The drill bit 1 is driven to rotate by the drill motor 2, and the drill bit 1 uses the spiral discharge groove 11 to disperse the feed to the surrounding area of ​​the drill bit 1.

[0061] The sampling chamber 34 contains a sample container 4, one end of which is connected to a drive shaft 5. A first sampling port 35 is provided on the side wall of the sampling chamber 34, and the position of the first sampling port 35 corresponds to the position of the sample container 4.

[0062] like Figure 5 As shown, the drive shaft 5 is cylindrical in shape, with a magnet 51 on one end face and a limiting lug 52 formed on the side wall near the magnet 51. The sample container 4 is also cylindrical with a hollow internal structure. A second sampling port 41 is provided on the side, and a connecting groove 42 is machined on the end facing the drive shaft 5. The connecting groove 42 mates with the limiting lug 52 formed on the end of the drive shaft 5. A magnet 51 is also provided at the bottom of the connecting groove 42. The drive shaft 5 and the sample container 4 are connected by the magnet 51 to achieve quick connection and disconnection of multiple sample containers 4 and the drive shaft 5.

[0063] The outer diameter of the sample container 4 is the same as the inner diameter of the sampling chamber 34, and the first sampling port 35 and the second sampling port 41 are misaligned in the non-sampling state. Therefore, the first sampling port 35 is closed during the insertion of the sampler 3 into the feed, so that the feed cannot enter the sample container 4.

[0064] Thus, one end of the drive shaft 5 with a limiting ear 52 is inserted into the connecting groove 42 of the sample container 4, and the magnet 51 at the end of the drive shaft 5 and the magnet 51 at the bottom of the connecting groove 42 attract each other, realizing a detachable connection between the sample container 4 and the drive shaft 5. The limiting ear 52 engages with the side wall of the connecting groove 42, so the drive shaft 5 drives the sample container 4 to rotate through the limiting ear 52.

[0065] See Figure 6 A rotating block 53 is provided on the side wall of the drive shaft 5 away from the magnet 51. The rotating block 53 has an L-shaped structure and a positioning pin 531 is formed on the rotating block 53. An outwardly extending flange 61 is formed on the side of the end cap 6 facing the sample container 4. A fixing block 63 is provided on the inner side of the outwardly extending flange 61. The fixing block 63 also has an L-shaped structure and a pin hole 631 is opened on the fixing block 63. The rotating block 53 and the fixing block 63 fit together. The position of the positioning pin 531 corresponds to the position of the pin hole 631. The positioning pin 531 is inserted into the pin hole 631 to restrict the axial movement of the drive shaft 5 and to position the sample container 4 so that the included angle between the second sampling port 41 on the sample container 4 and the first sampling port 35 on the sampler 3 is 90°.

[0066] A drive shaft hole 62 is provided at the center of the end cap 6. The drive shaft 5 passes through the drive shaft hole 62 and extends outward to be fixedly connected to the output end of the deflection motor 7. The deflection motor 7 is fixedly connected to the side of the end cap 6 away from the sample container 4. The output end of the deflection motor 7 drives the drive shaft 5 to rotate. The drive shaft 5 is engaged with the side wall of the connecting groove 42 by the limiting ear 52, thereby synchronously driving the sample container 4 to rotate.

[0067] End cap 6 is installed on the end of sampler 3 away from drill bit 1. An outwardly extending flange 61 is formed on the side of end cap 6 facing sample container 4. The outwardly extending flange 61 is inserted into the interior of sampler 3, and its outer diameter matches the inner diameter of sampler 3. A limiting finger 64 is provided on the side wall of end cap 6, and a limiting groove 37 is provided on the side wall of sampler 3 at a position corresponding to the limiting finger 64. End cap 6 fits snugly against the end face of sampler 3, ensuring that the limiting finger 64 is inserted into the limiting groove 37. The rotation of end cap 6 is restricted through the synergistic effect of the limiting finger 64 and the limiting groove 37.

[0068] The deflection motor 7 drives the sample container 4 to rotate via the drive shaft 5. The end cap 6 cannot rotate with the drive shaft 5 due to the action of the limiting finger 64. During the rotation of the drive shaft 5, the rotating block 53 and the fixed block 63 will gradually separate. The sample container 4 rotates 90° under the drive of the drive shaft 5 so that the second sampling port 41 is aligned with the first sampling port 35. The feed outside the sampler 3 overflows into the sample container 4 to achieve sampling.

[0069] A handle 36 is also provided on the side wall of the sampler 3. A first button 361 and a second button 362 are installed on the handle 36. The first button 361 is electrically connected to the drill motor 2, and the second button 362 is electrically connected to the deflection motor 7. A battery holder 38 is provided on the side wall of the sampler 3 opposite to the handle 36. Two parallel slots 381 are machined on the battery holder 38. The slots 381 have an L-shaped cross-section. The bottom of the battery 8 is provided with battery feet 81 that cooperate with the slots 381. The battery 8 is slidably connected to the battery holder 38 via the two battery feet 81, providing power to the drill motor 2 and the deflection motor 7.

[0070] The working principle of a single-arm rotary feed sampling device is as follows:

[0071] First, insert the end of the drive shaft 5 equipped with a magnet 51 into the connecting groove 42 on the sample container 4. The drive shaft 5 and the sample container 4 are connected by the attraction of the magnets 51. Then, a cap 6 is fitted onto the end of the drive shaft 5 away from the sample container 4, and the rotating block 53 on the drive shaft 5 is fastened to the fixing block 63 on the cap 6 to position the sample container 4 so that the deflection angle between the first sampling port 35 and the second sampling port 41 is 90°. The deflection motor 7 is then connected to the drive shaft 5. Finally, the sample container 4 and the drive shaft 5 are installed into the sampling chamber 34 of the sampler 3. The end face of the cap 6 is aligned with the end face of the sampler 3, and the limiting finger 64 is inserted into the limiting groove 37. The battery 8 is installed on the top of the sampler 3.

[0072] Hold the handle 36 of the sampler 3 and press the first button 361 to start the drill motor 2. The output of the drill motor 2 drives the drill 1 to rotate. When the drill 1 rotates, use the handle 36 to press the sampler 3 into the feed. The drill 1 drives the sampler 3 to the bottom of the feed. The first sampling port 35 on the sampler 3 and the second sampling port 41 on the sample container 4 are offset from each other, and the outer diameter of the sample container 4 is consistent with the inner diameter of the sampling chamber 34. This ensures that when the sampler 3 goes deep, the first sampling port 35 is in a closed state, and the feed cannot enter the sample container 4.

[0073] After reaching the required sampling depth, press the first button 361 again to stop the drill motor 2, and then press the second button 362 to start the deflection motor 7. The output end of the deflection motor 7 drives the drive shaft 5 to rotate 90°, and the drive shaft 5 drives the sample container 4 to rotate 90°, thereby aligning the first sampling port 35 with the second sampling port 41. The feed outside the sampler 3 overflows into the sample container 4 through the first sampling port 35 and the second sampling port 41, thus achieving sampling.

[0074] After sampling is completed, the end cap 6 is pulled out of the sampler 3, and the drive shaft 5 is pulled out at the same time. The drive shaft 5 is connected to the sample container 4 through the magnet 51. Thus, the sample container 4 is pulled out by the drive shaft 5. The sample container 4 containing the sample is removed, the empty sample container 4 is connected to the drive shaft 5 and put into the sampling chamber 34. The sampling operation is repeated to achieve sampling of multiple samples.

[0075] The above embodiments are merely a more detailed description of the present utility model. For those skilled in the art, modifications or equivalent substitutions can still be made to the technical solutions in the foregoing embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model patent.
