[0002] Feed is the general term for food for animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten types of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives, etc.

[0003] Clean feed belongs to a type of feed. When testing clean feed microorganisms, it is necessary to use a detection device. The existing detection device is a near-infrared spectrometer. When testing, the sample feed to be inspected is placed in a measuring cup, and then the measuring cup is placed on the near-infrared spectrometer and tested with its own detection head. However, because the amount of sampling is sometimes large, and the measuring cup of the existing near-infrared spectrometer is matched with it, resulting in a fixed size. Therefore, when sampling a large amount of feed, it is necessary to manually place the feed multiple times and conduct multiple samplings, which is more laborious. Summary of the invention

[0009] Furthermore, the fixing assembly includes a cylinder body fixedly connected to the top of the annular frame, a piston is arranged in the cylinder body, a screw rod is rotatably installed on the top of the piston, the top of the screw rod extends through the top wall of the cylinder body to the outside thereof, a threaded hole cooperating with the screw rod is opened on the cylinder body, an annular airbag is fixedly installed on the inner side of the annular frame, the annular airbag is connected to the cylinder body by a pipe, and the inner wall of the annular frame is provided with a channel for the pipe to pass through.

[0010] Furthermore, a round rod is fixedly installed on the outer side of the top plate, a side plate corresponding to the top plate is fixedly installed on the top of the detector, a second protrusion corresponding to the first protrusion is fixedly installed equidistantly on the inner side of the side plate, and a second arc surface matching the first arc surface is provided at the bottom of the second protrusion.

[0011] Furthermore, the spacing width between adjacent second protrusions is consistent with the width of the top plate, the second protrusions and the first protrusions are arranged alternately, and the second arc surface can contact the round rod.

[0012] Furthermore, the driving assembly includes a pair of second motors, and a slide groove is symmetrically opened on the top of the detector. The second motor is fixed on the side of the slide groove away from the support. The output shaft of the second motor is fixedly connected with a screw, and the other end of the screw is rotatably installed on the inner wall of the slide groove. The external threaded sleeve of the screw is provided with a moving block, and the moving block is fixedly connected to the support.

[0013] The present invention also provides a method for detecting using the clean feed microorganism detection device as described above, comprising the following steps:

[0014] S1. When in use, put the clean feed to be tested in a measuring cup, then put the measuring cup into the ring frame, with the top edge of the measuring cup resting on the top of the ring frame, then fix the measuring cup through a fixing assembly, start the detection head, and detect the feed through the glass plate at the bottom of the measuring cup, and at the same time start the first motor so that its output shaft rotates with the gear, and cooperates with the teeth to rotate the ring frame, thereby cooperating with the fixing assembly to rotate the measuring cup. The position of the detection head does not correspond to the center of the measuring cup. Relative to the eccentric setting of the measuring cup, the detection range length of the detection head is consistent with the radius of the bottom of the measuring cup. Through the rotation of the measuring cup, the detection head can perform a more comprehensive detection of the feed in the measuring cup;

[0015] S2. When it is necessary to replace a measuring cup whose bottom radius is larger than the measuring range of the detection head, the fixing component is used to fix the measuring cup whose bottom radius is larger than the measuring range of the detection head. After the fixing is completed, the above operation is performed for detection. Since the size of the measuring cup has changed, the radius of the bottom of the measuring cup is larger than the measuring range of the detection head. When the measuring cup is rotated for detection, some areas far away from the center point of the measuring cup cannot be detected. At this time, the detection of the detection head and the first motor are suspended, and the support is driven by the driving component to move horizontally with the annular frame and the measuring cup. The lifting component is used to drive the annular frame to lift the measuring cup, so that the measuring cup is lifted while moving horizontally. At this time, the bottom of the measuring cup can leave the top of the detector, so that during the translation process, the fine impurities on the bottom of the measuring cup will not conflict with the top of the detector, thereby grinding the bottom of the measuring cup, so that the bottom of the measuring cup can be protected;

[0016] S3. As the measuring cup translates, the lifting assembly gradually cancels the lifting of the annular frame, causing the annular frame and the measuring cup to drop under the action of gravity and finally reset, so that the bottom of the measuring cup fits the detection head. The above operation can then be repeated for detection, and the feed in the entire measuring cup can be detected. When the amount of feed to be detected is large, a comprehensive detection of the feed can still be performed after switching to a measuring cup with a bottom radius larger than the measuring range of the detection head, thereby reducing the number of detections and saving manpower.

[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention can realize the replacement of the measuring cup, and after the replacement, by adjusting the position of the measuring cup, it is possible to achieve a comprehensive detection of the feed in the measuring cup, and by replacing a large measuring cup with a bottom radius larger than the measuring range of the detection head, the number of operations is greatly reduced, saving manpower, and in the process of adjusting the position of the measuring cup, the bottom of the measuring cup can be protected to prevent the bottom of the measuring cup from being worn;

[0019] 2. The present invention can ensure that the measuring cup can be smoothly lowered and reset during the adjustment process, so that it fits with the detection head, thereby ensuring the smooth progress of subsequent detection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] The present invention provides a clean feed microorganism detection device, such as Figures 1 to 8 As shown, it includes a detector 1, a support 2 is provided on the top of the detector 1, the detector is a near-infrared spectrometer, a detection head 3 is provided on the top of the detector 1, the detection head 3 is the detection head on the near-infrared spectrometer, a measuring cup 5 is a measuring cup used in conjunction with the near-infrared spectrometer, a glass plate is provided at the bottom, an opening is provided in the middle of the support 2, the detection head 3 corresponds to the position of the opening, an annular frame 4 is provided in the opening, a measuring cup 5 is provided inside the annular frame 4, a fixing component for fixing the measuring cup 5 is provided on the annular frame 4, teeth 6 are equidistantly arranged around the outer side of the annular frame 4, a mounting groove is provided on the top of the support 2, a first motor 7 is fixedly installed in the mounting groove, a gear 8 meshing with the teeth 6 is fixedly installed on the output shaft of the first motor 7, a lifting component for driving the annular frame 4 to lift is provided on the outer side of the annular frame 4, a driving component for driving the horizontal movement is provided at the bottom of the support 2, and the thickness of the gear 8 is greater than the thickness of the teeth 6.

[0031] When in use, put the clean feed to be tested in the measuring cup 5, then put the measuring cup 5 into the annular frame 4, the top edge of the measuring cup 5 is placed on the top of the annular frame 4, then the measuring cup 5 is fixed by the fixing component, and the detection head 3 is started to detect the feed through the glass plate at the bottom of the measuring cup 5, and at the same time, the first motor 7 is started to make its output shaft rotate with the gear 8, and the teeth 6 rotate with the annular frame 4, so as to cooperate with the fixing component to rotate the measuring cup 5. The position of the detection head 3 does not correspond to the center of the measuring cup 5. Relative to the eccentric setting of the measuring cup 5, the detection range length of the detection head 3 is consistent with the radius of the bottom of the measuring cup 5. Through the rotation of the measuring cup 5, the detection head 3 can be used to perform a more comprehensive detection of the feed in the measuring cup 5. When it is necessary to replace the measuring cup 5 with a bottom radius larger than the measuring range of the detection head 3, the fixing component is used to fix the measuring cup 5 with a bottom radius larger than the measuring range of the detection head 3. After the fixation is completed, the detection is performed in the same way as above. Due to the change in the size of the measuring cup 5, the radius of the bottom of the measuring cup 5 is larger than the measuring range of the detection head 3. When the measuring cup 5 is rotated for detection, there is a long distance. In the case where some areas away from the center point of the measuring cup 5 cannot be detected, the detection of the detection head 3 and the first motor 7 are suspended, and the support 2 is driven by the driving component to make it move horizontally with the annular frame 4 and the measuring cup 5, and the lifting component drives the annular frame 4 to lift the measuring cup 5, so that the measuring cup 5 moves horizontally while being lifted. At this time, the bottom of the measuring cup 5 can leave the top of the detector 1, so that in the process of translation, the fine impurities at the bottom of the measuring cup 5 will not conflict with the top of the detector 1, thereby grinding the bottom of the measuring cup 5, so that the measuring cup can be protected. 5, as the measuring cup 5 translates, the lifting assembly gradually cancels the lifting of the annular frame 4, so that the annular frame 4 and the measuring cup 5 descend under the action of gravity, and finally reset, so that the bottom of the measuring cup 5 fits with the detection head 3, and then the above operation can be repeated for detection, and finally the feed in the entire measuring cup 5 can be detected, so that when the amount of feed to be detected is large, after switching to the measuring cup 5 with a bottom radius larger than the measuring range of the detection head 3, the feed can still be fully tested, and the microbial content can be detected, thereby reducing the number of tests and saving manpower.

[0032] like Figure 1 and Figure 6 As shown, the lifting assembly includes a swivel 9, an annular groove is provided at the bottom of the side of the annular frame 4, the swivel 9 is rotatably installed in the annular groove, a top plate 10 is symmetrically fixedly installed at the bottom of the swivel 9, the bottom of the top plate 10 is arranged in an arc shape, and a first protrusion 11 cooperating with the top plate 10 is equidistantly provided at the top of the detector 1, a first arc surface 12 is provided on the top of the first protrusion 11, and the inner side of the top plate 10 is in contact with the outer side of the support 2.

[0033] When the annular frame 4 rotates, the swivel 9 cannot rotate due to the fit between the top plate 10 and the outer side of the support 2. Therefore, the annular frame 4 rotates freely relative to the swivel 9. As the support 2 moves, the annular frame 4, the swivel 9, and the top plate 10 move along with it. After the top plate 10 contacts the first curved surface 12, as the top plate 10 translates, its bottom is squeezed by the first curved surface 12, and the swivel 9, the annular frame 4, and the measuring cup 5 are lifted. When the top plate 10 moves to the center of the first curved surface 12, the measuring cup 5 rises to the highest position. Then, as the top plate 10 continues to translate, the top plate 10 descends along the first curved surface 12 under the action of gravity, causing the measuring cup 5 to descend accordingly and finally fit with the detection head 3.

[0034] like Figure 1 As shown, the spacing width between adjacent first protrusions 11 is consistent with the width of the top plate 10 .

[0035] When the top plate 10 starts to move horizontally, it can contact with the first curved surface 12 and rise.

[0036] like Figures 1 to 3 and Figure 7 As shown, the fixing assembly includes a cylinder body 13 fixedly connected to the top of the annular frame 4, a piston 14 is arranged in the cylinder body 13, a screw rod 15 is rotatably installed on the top of the piston 14, the top of the screw rod 15 passes through the top wall of the cylinder body 13 and extends to the outside thereof, a threaded hole matching with the screw rod 15 is opened on the cylinder body 13, an annular air bag 16 is fixedly installed on the inner side of the annular frame 4, the annular air bag 16 is connected to the cylinder body 13 by a pipe 17, and the inner wall of the annular frame 4 is provided with a channel for the pipe 17 to pass through.

[0037] Rotate the screw rod 15 forward to make it rise along the cylinder body 13, thereby raising the piston 14, and then cooperate with the pipe 17 to draw the air in the annular airbag 16 into the cylinder body 13, so that the annular airbag 16 becomes deflated. At this time, the measuring cup 5 can be placed in the annular frame 4. At this time, reverse the screw rod 15 to make it descend, and vice versa to achieve the descending of the cylinder body 13, squeeze the air in the cylinder body 13 outward, and the air enters the annular airbag 16, so that the outer side of the measuring cup 5 is clamped, completing the fixation of the measuring cup 5. When the annular frame 4 rotates, the friction between the annular airbag 16 and the measuring cup 5 can drive the measuring cup 5 to rotate.

[0038] like Figure 1 and Figure 5 As shown, a round rod 18 is fixedly installed on the outer side of the top plate 10, a side plate 19 corresponding to the top plate 10 is fixedly installed on the top of the detector 1, a second protrusion 20 corresponding to the first protrusion 11 is fixedly installed equidistantly on the inner side of the side plate 19, and a second curved surface 21 matching the first curved surface 12 is provided at the bottom of the second protrusion 20.

[0039] As the top plate 10 moves horizontally, when its bottom moves to the middle position of the top of the first curved surface 12, as the top plate 10 continues to move, the round rod 18 contacts the second curved surface 21 of the second protrusion 20, and the round rod 18 is squeezed by the second curved surface 21, causing it to descend, thereby ensuring that the top plate 10 can move downward stably, and then ensuring that the swivel 9, the annular frame 4, and the measuring cup 5 can be smoothly lowered and reset, and there will be no situation where the annular frame 4 cannot naturally descend under the action of gravity due to excessive friction between the gear 8 and the teeth 6 or excessive friction between the annular frame 4 and the support 2, thereby ensuring that the measuring cup 5 can be lowered and reset.

[0040] like Figure 5 As shown, the spacing width between adjacent second protrusions 20 is consistent with the width of the top plate 10 , the second protrusions 20 and the first protrusions 11 are arranged alternately, and the second arc surface 21 can contact the round rod 18 .

[0041] After the bottom of the top plate 10 leaves the middle of the top end of the first curved surface 12 , the round rod 18 can contact the second curved surface 21 , thereby being squeezed and lowered.

[0042] like Figure 1 and Figure 8 As shown, the driving assembly includes a pair of second motors 24, and a slide groove is symmetrically opened on the top of the detector 1. The second motor 24 is fixed on the side of the slide groove away from the support 2. The output shaft of the second motor 24 is fixedly connected with a screw rod 23, and the other end of the screw rod 23 is rotatably installed on the inner wall of the slide groove. The external threaded sleeve of the screw rod 23 is provided with a moving block 22, and the moving block 22 is fixedly connected to the support 2.

[0043] Start the second motor 24 to rotate its output shaft forward and drive the screw 23 to rotate, drive the moving block 22 to move along the slide slot, and thus drive the support 2 to move horizontally. Start the second motor 24 to reverse its output shaft, and vice versa, the support 2 can be reset.

[0044] The present invention provides a method for detecting using the clean feed microorganism detection device as described above, comprising the following steps:

[0045] S1. When in use, put the clean feed to be tested in the measuring cup 5, then put the measuring cup 5 into the annular frame 4, the top edge of the measuring cup 5 is placed on the top of the annular frame 4, then fix the measuring cup 5 through the fixing assembly, start the detection head 3, and make it detect the feed through the glass plate at the bottom of the measuring cup 5, and at the same time start the first motor 7 so that its output shaft drives the gear 8 to rotate, and cooperates with the teeth 6 to drive the annular frame 4 to rotate, so as to cooperate with the fixing assembly to drive the measuring cup 5 to rotate, the position of the detection head 3 does not correspond to the center of the measuring cup 5, and relative to the eccentric setting of the measuring cup 5, the detection range length of the detection head 3 is consistent with the radius of the bottom of the measuring cup 5, and through the rotation of the measuring cup 5, the detection head 3 can perform a more comprehensive detection of the feed in the measuring cup 5;

[0046] S2. When it is necessary to replace the measuring cup 5 whose bottom radius is larger than the measuring range of the detection head 3, the fixing component is used to fix the measuring cup 5 whose bottom radius is larger than the measuring range of the detection head 3. After the fixing is completed, the above operation is performed for detection. Since the size of the measuring cup 5 has changed, the radius of the bottom of the measuring cup 5 is larger than the measuring range of the detection head 3. When the measuring cup 5 rotates for detection, some areas away from the center point of the measuring cup 5 cannot be detected. At this time, the detection of the detection head 3 and the first motor 7 are suspended, and the support 2 is driven by the driving component to make it move horizontally with the annular frame 4 and the measuring cup 5, and the lifting component is used to drive the annular frame 4 to lift the measuring cup 5, so that the measuring cup 5 is lifted while moving horizontally. At this time, the bottom of the measuring cup 5 can leave the top of the detector 1, so that in the process of translation, the fine impurities at the bottom of the measuring cup 5 will not conflict with the top of the detector 1, thereby grinding the bottom of the measuring cup 5, so that the bottom of the measuring cup 5 can be protected;

[0047] S3. As the measuring cup 5 translates, the lifting assembly gradually cancels the lifting of the annular frame 4, causing the annular frame 4 and the measuring cup 5 to descend under the action of gravity and finally reset, so that the bottom of the measuring cup 5 fits the detection head 3. The above operation can then be repeated for detection, and finally the feed in the entire measuring cup 5 can be detected. When the amount of feed to be detected is large, a comprehensive detection of the feed can still be performed after switching to a measuring cup 5 with a bottom radius larger than the measuring range of the detection head 3, thereby reducing the number of detections and saving manpower.

[0048] Working principle: When in use, put the clean feed to be tested in the measuring cup 5, then put the measuring cup 5 into the annular frame 4, the top edge of the measuring cup 5 is placed on the top of the annular frame 4, and the screw rod 15 is reversed to make it descend, so as to realize the descent of the cylinder 13, squeeze the air in the cylinder 13 outward, and the air enters the annular airbag 16, so that the outer side of the measuring cup 5 is clamped, and the fixing of the measuring cup 5 is completed, and the detection head 3 is started to detect the feed through the glass plate at the bottom of the measuring cup 5, and at the same time, the first motor 7 is started to make its output shaft rotate with the gear 8, and the gear 6 rotates with the annular frame 4, and the friction between the annular airbag 16 and the measuring cup 5 rotates with the measuring cup 5. The position of the detection head 3 does not correspond to the center of the measuring cup 5, and is eccentrically set relative to the measuring cup 5. The length of the detection range of the detection head 3 is consistent with the radius of the bottom of the measuring cup 5. Through the rotation of the measuring cup 5, the detection head 3 can be used to perform a more comprehensive detection of the feed in the measuring cup 5. When it is necessary to replace the measuring cup 5 whose bottom radius is larger than the measuring range of the detection head 3, the screw rod 15 is rotated forward to make it rise along the cylinder body 13, thereby bringing the piston 14 up, and then cooperating with the pipeline 17 to draw the air in the annular airbag 16 into the cylinder body 13, so that the annular airbag 16 becomes deflated. At this time, the measuring cup 5 whose bottom radius is larger than the measuring range of the detection head 3 can be placed in the annular frame 4, and the screw rod 15 is reversed to make it descend, and vice versa to achieve the descending of the cylinder body 13, squeezing the air in the cylinder body 13 outward, and the air enters the annular airbag 16, so that the outer side of the measuring cup 5 is clamped, completing the measurement of the measuring cup. 5 is fixed. After the fixation is completed, the above operation is performed for detection. Due to the change in the size of the measuring cup 5, the radius of the bottom of the measuring cup 5 is now larger than the measuring range of the detection head 3. When the measuring cup 5 is rotated for detection, there is a situation where a part of the area away from the center point of the measuring cup 5 cannot be detected. At this time, the detection of the detection head 3 and the first motor 7 are suspended, and the second motor 24 is started to rotate its output shaft forward to rotate the screw 23, drive the moving block 22 to move along the slide groove, thereby driving the support 2 to move horizontally, thereby driving the annular frame 4 and the measuring cup 5 to move horizontally, and then driving the rotating ring 9 and the top plate 10 to move. After the top plate 10 contacts the first curved surface 12, as the top plate 10 moves horizontally, its bottom is squeezed by the first curved surface 12, and the rotating ring 9 and the annular frame are pressed horizontally. 4. The measuring cup 5 is lifted. When the top plate 10 moves to the center of the first arc surface 12, the measuring cup 5 rises to the highest position. Then, as the top plate 10 continues to translate, the top plate 10 descends along the first arc surface 12 under the action of gravity, causing the measuring cup 5 to descend accordingly and finally fit with the detection head 3. Then, the above operation can be repeated for detection, so that the position corresponding to the detection head 3 and the bottom of the measuring cup 5 is adjusted, so that the detection range covers the previously undetected area, and finally the feed in the entire measuring cup 5 can be detected. When the amount of feed to be detected is large, after switching the measuring cup 5 whose bottom radius is larger than the measuring range of the detection head 3, the feed can still be fully detected, thereby reducing the number of detection times and saving manpower. In addition, the measuring cup 5 is lifted during the translation process.The measuring cup 5 is lifted while moving horizontally. At this time, the bottom of the measuring cup 5 can leave the top of the detector 1, so that in the process of translation, the fine impurities at the bottom of the measuring cup 5 will not collide with the top of the detector 1, thereby grinding the bottom of the measuring cup 5, so that the bottom of the measuring cup 5 can be protected. After the detection is completed, the second motor 24 can be started to reverse its output shaft, and vice versa to achieve the reset of the support 2; as the top plate 10 moves horizontally, when its bottom moves to the middle position of the top of the first arc surface 12, as the top plate 10 continues to move, the round rod 18 conflicts with the second arc surface 21 of the second protrusion 20, and the round rod 18 is squeezed by the second arc surface 21, causing it to drop, thereby ensuring that the top plate 10 can move downward stably, and then ensuring that the swivel 9, the annular frame 4, and the measuring cup 5 can be smoothly lowered and reset, and there will be no situation where the annular frame 4 cannot naturally drop under the action of gravity due to excessive friction between the gear 8 and the teeth 6 or excessive friction between the annular frame 4 and the support 2, thereby ensuring that the measuring cup 5 can drop and reset.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.

4. A method for detecting using the clean feed microorganism detection device as described in claim 3, characterized in that: The steps include: S1. When in use, the clean feed to be tested is placed in the measuring cup (5), and then the measuring cup (5) is placed in the annular frame (4), with the top edge of the measuring cup (5) resting on the top of the annular frame (4). Then, the measuring cup (5) is fixed by a fixing assembly, and the detection head (3) is started so that the detection head (3) can detect the feed through the glass plate at the bottom of the measuring cup (5). At the same time, the first motor (7) is started so that its output shaft drives the gear (8) to rotate, and the gear teeth (6) drive the annular frame (4) to rotate, thereby driving the measuring cup (5) in cooperation with the fixing assembly. The position of the detection head (3) does not correspond to the center of the measuring cup (5). With respect to the eccentric setting of the measuring cup (5), the detection range length of the detection head (3) is consistent with the radius of the bottom of the measuring cup (5). Through the rotation of the measuring cup (5), the detection head (3) can perform a more comprehensive detection of the feed in the measuring cup (5). S2. When it is necessary to replace the measuring cup (5) whose bottom radius is larger than the measuring range of the detection head (3), the fixing component is used to fix the measuring cup (5) whose bottom radius is larger than the measuring range of the detection head (3). After the fixing is completed, the detection is performed in the same manner as above. Since the size of the measuring cup (5) has changed, the radius of the bottom of the measuring cup (5) is larger than the measuring range of the detection head (3). When the measuring cup (5) is rotated for detection, some areas away from the center point of the measuring cup (5) cannot be detected. At this time, the detection head (3) is suspended. The detection and first motor (7) drive the support (2) through the driving component to make it move horizontally with the annular frame (4) and the measuring cup (5), and cooperate with the lifting component to drive the annular frame (4) to lift the measuring cup (5), so that the measuring cup (5) moves horizontally while being lifted. At this time, the bottom of the measuring cup (5) can leave the top of the detector (1), so that in the process of translation, fine impurities at the bottom of the measuring cup (5) will not conflict with the top of the detector (1), thereby grinding the bottom of the measuring cup (5), so that the bottom of the measuring cup (5) can be protected; S3. As the measuring cup (5) moves horizontally, the lifting assembly gradually stops lifting the annular frame (4), causing the annular frame (4) and the measuring cup (5) to descend under the action of gravity and finally reset, so that the bottom of the measuring cup (5) fits the detection head (3). The above operation can then be repeated to perform detection, and finally the feed in the entire measuring cup (5) can be detected.
