Description

Technical Field

[0001] The invention relates to the technical field of raw milk detection, in particular to a mixing sampling device for raw milk detection. Background Art

[0002] Raw milk testing covers many aspects, including but not limited to the determination of protein and fat content, as well as the freshness, thermal stability, water content, ash content, temperature monitoring, pH value and conductivity of raw milk. In the dairy cow epidemic prevention work, in order to conduct regular quarantine for infectious diseases such as tuberculosis and brucellosis, it is also necessary to conduct corresponding microbial testing on raw milk samples. These tests are not only related to the basic nutritional components and quality of raw milk, but also to the safety and purity of raw milk, ensuring that the qualified rate of immune antibodies meets national requirements and at the same time reducing the occurrence and spread of diseases.

[0003] During the raw milk testing process, when sampling the raw milk, since the raw milk is easily precipitated at the bottom after being placed for a period of time, in order to ensure the accuracy of the test results, it is necessary to configure not only samplers, sample bottles, etc., but also corresponding stirrers. When sampling from a milk bucket, the stirrer should be rotated up and down more than 20 times. When sampling in a larger milk storage tank, an electric stirrer should be used to stir the raw milk for more than 20 minutes to evenly distribute the various components of the raw milk before sampling the raw milk. In this way, when the raw milk storage container is relatively large, it takes a long time to wait for the raw milk to be stirred evenly, and it is more troublesome for the staff to extend the stirrer into the stirring container and take the stirrer out of the storage container.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The sampling tube is provided with a central tube inside, so that the sampling tube and the central tube can be extended into the raw milk container. Since the sampling tube and the central tube are connected with the outside, and the inside of the central tube is connected with the outside through the connecting groove and the circular groove, the raw milk can be filled into the sampling tube and the central tube. After the bottom surface of the rubber ring contacts the bottom surface of the raw milk storage container, the raw milk inside the sampling tube can be separated from other raw milk by the rubber ring, so that the raw milk in the upper and lower layers can be obtained inside the sampling tube. At this time, the raw milk can flow in the sampling tube by moving the sliding block up and down, so that the raw milk in the sampling tube can be mixed. The sliding block can be moved to the bottom of the central tube, and the sliding block is fitted with the sliding ring, so that the inside of the central tube is blocked by the sliding block. In this way, when the sampling tube is moved upward, the raw milk inside the central tube can be taken out to sample the raw milk. When sampling, the amount of raw milk inside the sampling tube is relatively small. In this way, the raw milk inside the sampling tube can be mixed more quickly. When the volume of the raw milk storage container is relatively large, it does not need to spend a long time to mix all the raw milk in the container, which is conducive to rapid sampling and does not need to be equipped with a large agitator, so it is convenient for the staff to quickly take samples.

[0018] 2. A number of arc grooves are provided on the top surface of the positioning plate. After the sampling is completed and the raw milk is moved into the processing module, the sampling tube can be moved upward so that the sampling tube is attached to the bottom of the positioning plate. At this time, clean water can be transported to the inside of the conveying frame through the conveying pipe. The clean water can pass through the arc groove and enter between the sampling tube and the telescopic sleeve, between the sampling tube and the central tube, and inside the central tube, so as to flush the sampling tube and the central tube. The clean water inside the sampling tube can fall on the sliding block to flush the rotating frame and the sliding ring. After the flushing is completed, the direction of the fixed tube can be adjusted so that the top of the fixed tube corresponds to the air outlet pipe. At this time, air can be supplied to the inside of the sampling tube, so as to dry the water stains on the surface of the sampling tube and the central tube, so as to facilitate the next raw milk sampling.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-11In an embodiment of the present invention, a mixing sampling device for raw milk detection includes a support frame 100, an adjustment module 300 is arranged on the top of the support frame 100, a sampling module 200 is arranged on one side of the adjustment module 300, the sampling module 200 includes a sampling tube 210, a central tube 220 is arranged inside the sampling tube 210, a sliding block 230 is slidably connected to the top of the inner side of the central tube 220, a sliding ring 240 is slidably connected to the bottom of the sliding block 230, a circular groove 232 is opened on the bottom surface of the sliding block 230, and two inner sides of the circular groove 232 are opened to extend to the top surface of the sliding block 230 The connecting groove 231 and the inner side surface of the sliding ring 240 are fixedly connected with two fixed blocks 242, and the corresponding circular grooves 232 on the opposite sides of the two fixed blocks 242 are fixedly connected with blocking rods 241, the bottom of the side of the sampling tube 210 is fixedly connected with a rubber ring 211, and the side of the central tube 220 is fixedly connected with two pad rods 221 fixedly connected to the inner side surface of the sampling tube 210, and the top surface of the fixed block 242 is fixedly connected with a limiting rod 243, and the bottom surface of the sliding block 230 is provided with two limiting grooves 233 corresponding to the limiting rod 243, and the inner side surfaces of the limiting grooves 233 are slidably connected with the sides of the adjacent limiting rods 243.

[0036] Specifically, the sampling module 200 can be moved downward by adjusting the module 300, and the sampling tube 210 and the central tube 220 can be extended into the raw milk container. Since the sampling tube 210 and the central tube 220 are connected to the outside, and the inside of the central tube 220 is connected to the outside through the connecting groove 231 and the circular groove 232, the raw milk can be filled into the sampling tube 210 and the central tube 220, and the raw milk in upper and lower layers can be obtained in the sampling tube 210. After the bottom surface of the rubber ring 211 contacts the bottom surface of the raw milk storage container, the raw milk in the sampling tube 210 can be separated from other raw milk by the rubber ring 211. At this time, the sliding block 230 can be moved up and down to make the raw milk flow in the sampling tube 210, so as to mix the raw milk in the sampling tube 210.

[0037] An annular rubber pad in contact with the central tube 220 is provided on the side of the sliding ring 240. When the sliding block 230 moves upward, the central tube 220 can provide a certain resistance to the movement of the sliding ring 240 through the annular rubber pad, so that the sliding block 230 and the sliding ring 240 can maintain a certain distance. After the top of the limiting rod 243 contacts the bottom of the limiting groove 233, the sliding block 230 can pull the limiting rod 243 and the sliding ring 240 upward through the limiting groove 233, so that part of the raw milk can pass through the connecting groove 231 and the circular groove 232 into between the sliding block 230 and the sliding ring 240, and then pass through the inside of the sliding ring 240. The length of the central tube 220 is less than the length of the sampling tube 210, so that the sliding block 230 can push part of the raw milk to move upward, so that part of the raw milk passes through the top of the sliding block 230 into the sampling tube 210 and the central tube 220, thereby stirring the raw milk through the sliding block 230, and when the sliding ring 240 moves downward, due to the resistance of the central tube 220 to the movement of the sliding ring 240, the sliding block 230 can first be pressed against the top surface of the sliding ring 240, so that the blocking rod 241 is inserted into the circular groove 232, and the connecting groove 231 is blocked by the blocking rod 241, and the sliding block 230 can push the sliding ring 240 to move downward. At this time, the raw milk will no longer pass through the inside of the circular groove 232, and the sliding block 230 and the sliding ring 240 can squeeze the raw milk inside the central tube 220 downward, and the raw milk can pass through the bottom of the central tube 220 to enter between the sampling tube 210 and the central tube 220, and the raw milk between the sampling tube 210 and the central tube 220 can enter the inside of the sampling tube 210 from the top of the central tube 220, so that the raw milk flows up and down, and then the raw milk is stirred;

[0038] The sliding block 230 can be moved to the bottom of the central tube 220 so that the sliding block 230 fits with the sliding ring 240, thereby blocking the inside of the central tube 220 through the sliding block 230. In this way, when the sampling tube 210 is moved upward, the raw milk inside the central tube 220 can be taken out and the raw milk can be sampled. When sampling, the amount of raw milk inside the sampling tube 210 is relatively small, so the raw milk inside the sampling tube 210 can be mixed more quickly. When the volume of the raw milk storage container is relatively large, it does not need to spend a long time to mix all the raw milk in the container, which is conducive to rapid sampling and does not require a large agitator, which is convenient for staff to quickly take samples.

[0041] In a specific implementation, after the sampling module 200 completes sampling of the raw milk, the sampling tube 210 can be moved upwards through the adjustment module 300 and rotated to the top of the processing module 400. At this time, the top cover 440 can be squeezed by the sampling module 200 to rotate the top cover 440 toward the opening groove, and then the sliding block 230 can be moved downwards out of the center tube 220 to make the raw milk fall into the processing cylinder 420. Then the sampling module 200 is removed from the top of the processing module 400. At this time, under the action of the torsion spring 450, the rotating shaft 442 can be rotated, so that the support rod 441 and the top cover 440 are rotated to the original position, so that the top cover 440 blocks the top of the processing tube 420 again, and then the driving shaft 412 can be driven to rotate by the power motor 411, and the driving shaft 412 can drive the gear ring 422 to rotate by the driving gear 413, so that the processing tube 420 can rotate, and the processing tube 420 can stir the raw milk through the stirring plate 421, so as to further process the raw milk, and when it is necessary to take mixed samples, after sending multiple samples into the processing tube 420, the multiple samples can be stirred and mixed inside the processing tube 420.

[0046] In a specific implementation, the adjusting screw rod 333 can limit the height of the lifting block 332, thereby limiting the height of the adjusting seat 331, and maintaining the position of the sampling tube 210 and the sliding block 230. An adjusting motor 314 can drive a transmission shaft 315 to rotate. A transmission shaft 315 can drive a connecting rod 1 311 to rotate through an adjacent connecting gear 313. The connecting rod 1 311 can drive an adjusting screw rod 333 to rotate through a pulley 1 316 and a pulley 2 334. The rotation of an adjusting screw rod 333 can make the position of the sampling tube 210 and the sliding block 230 be maintained. The lifting block 332 at the top moves along the inside of the adjustment frame 330, and the lifting block 332 can drive the adjustment seat 331 to rotate, so that the adjustment seat 331 at the top drives the positioning plate 350 to move, and the positioning plate 350 drives the linkage rod 351 to move, thereby driving the sliding block 230 to move, so that the sliding block 230 moves up and down inside the central tube 220 to stir the raw milk, and after the mixing is completed, the sliding block 230 can be moved to the bottom of the central tube 220, and the inside of the central tube 220 is blocked by the sliding block 230;

[0047] Another adjusting motor 314 can drive another transmission shaft 315 to rotate, and another transmission shaft 315 can drive the second connecting rod 312 to rotate through the adjacent connecting gear 313, and the second connecting rod 312 can drive another adjusting screw rod 333 to rotate through the first pulley 316 and the second pulley 334, so that the adjusting seat 331 and the lifting block 332 at the bottom can move up and down, and the adjusting seat 331 at the bottom can drive the positioning frame 340 to move, and the positioning frame 340 can drive the sampling tube 210 to move, and the sampling tube 210 can drive the central tube 220 to move through the pad rod 221, so that the sampling tube 210 and the central tube 220 move downward and insert into the raw milk, and after the sampling is completed, the sampling tube 210 and the central tube 220 are moved upward out of the raw milk;

[0048] When the sampling tube 210 and the central tube 220 are inserted downward into the raw milk, the position of the sliding block 230 can be maintained by the positioning plate 350 and the linkage rod 351, and the central tube 220 can move the sliding ring 240 downward under the action of friction, so that the sliding ring 240 and the sliding block 230 are kept separated, so that the inside of the central tube 220 is kept connected with the outside, and the sliding block 230 moves inside the central tube 220 to mix the raw milk in the sampling tube 210 and the central tube 220, and then the sliding block 230 and the sliding ring 240 are pushed to the bottom of the central tube 220, so that the sliding block 230 and the sliding ring 240 is tightly attached, when the blocking rod 241 is inserted into the circular groove 232, the two adjusting screws 333 can rotate synchronously, so that the sampling tube 210, the central tube 220, the sliding block 230, and the sliding ring 240 can move upward synchronously, the sliding block 230 can support the raw milk, and the central tube 220 can make the sliding ring 240 move upward synchronously under the action of friction. Since the blocking rod 241 is located inside the circular groove 232 at this time, the raw milk will only squeeze the side of the blocking rod 241, so that the raw milk will not exert downward pressure on the sliding ring 240, thereby allowing the sliding ring 240 to move upward smoothly through the central tube 220.

[0049] like Fig.12 , 14 As shown, in the present embodiment, the bottom surface of the circular plate 321 is fixedly connected to a conveying frame 322 in contact with the top surface of the positioning plate 350, the side surface of the conveying frame 322 is connected to a conveying pipe 380, the top surface of the positioning plate 350 is provided with a plurality of arc grooves, the bottom surfaces of the two adjustment frames 330 are fixedly connected to a bottom plate 360, the top surface of the bottom plate 360 ​​is fixedly connected to a telescopic sleeve 361 fixedly connected to the bottom surface of the positioning frame 340, the top surface of the fixed box 310 is fixedly connected to a conveying box 370, the top surface of the conveying box 370 is provided with a driving motor 373, the inner side surface of the conveying box 370 is rotatably connected to a rotating seat 372, and the output end of the driving motor 373 is transmission-connected to the top surface of the rotating seat 372, the bottom surface of the rotating seat 372 is fixedly connected to a transmission rod 371 rotationally connected to the inner side surface of the conveying box 370, and the side surface of the transmission rod 371 is rotationally connected to the inner side surface of the top of the fixed box 310 The side of the transmission rod 371 is rotatably connected to the inner side of the connecting rod 312, and the bottom of the side of the transmission rod 371 is rotatably connected to the inner side of the rotating frame 320, the delivery pipe 380 extends to the inside of the transmission rod 371, and the inner side of the rotating seat 372 is fixedly connected to a fixed pipe 375 connected to the top of the delivery pipe 380, and an air pump 376 is arranged inside the delivery box 370 corresponding to the fixed pipe 375, and the inner side of the delivery box 370 is fixedly connected to a baffle ring 374 rotatably connected to the side of the rotating seat 372, the air outlet end of the air pump 376 is connected to an air outlet pipe 378 corresponding to the top of the fixed pipe 375, and the side of the air outlet pipe 378 is fixedly connected to the inner side of the baffle ring 374, the air inlet end of the air pump 376 is connected to an air inlet pipe 377 extending to the outside of the delivery box 370, and the inner side of the delivery box 370 is fixedly connected to a water pipe 379 fixedly connected to the inner side of the baffle ring 374.

[0050] During specific implementation, the driving motor 373 can drive the rotating seat 372 to rotate, the rotating seat 372 can drive the transmission rod 371 to rotate in the connecting rod 312, and the transmission rod 371 can drive the rotating frame 320 to rotate, so that the sampling module 200 is rotated through the adjusting frame 330 to adjust the position of the sampling module 200. The sampling module 200 can be adjusted to the top of the raw milk container first, and then the central tube 220 is moved downward and inserted into the raw milk by adjusting the rotation of the screw rod 333 to sample the raw milk. After the raw milk is mixed by the up and down movement of the sliding block 230 and the sliding ring 240, the sliding block 230 and the sliding ring 240 are moved to the bottom of the central tube 220, and then the central tube 220 and the sliding block 230 are moved upward synchronously to move the sampling module 200 to the top of the raw milk container. The sampling tube 210 is moved out of the raw milk to complete the sampling. At the same time, the positioning plate 350 will be pressed against the bottom surface of the conveying frame 322, and the telescopic sleeve 361 will be extended and unfolded to cover the sampling tube 210. Then, the rotating seat 372 can be driven to rotate by the driving motor 373, and the position of the sampling module 200 is adjusted by the rotating frame 320. The sampling module 200 is rotated to the top of the processing tube 420. The bottom plate 360 ​​can squeeze the top cover 440 to align the central tube 220 with the inside of the processing tube 420. Then, the sampling tube 210 and the central tube 220 can continue to move upward, so that the positioning frame 340 is pressed against the bottom surface of the positioning plate 350. At this time, the sliding block 230 and the sliding ring 240 will move out of the central tube 220, so that the raw milk falls into the processing tube 420 from the bottom of the central tube 220.

[0051] After all the raw milk in the central tube 220 falls out, the sampling module 200 can be rotated to the top of the receiving frame 120 by driving the motor 373. At this time, the fixed tube 375 will correspond to the water pipe 379. After the water pipe 379 is connected to the water source, clean water can be transported to the inside of the fixed tube 375 through the water pipe 379. The clean water can enter the delivery pipe 380, and then enter the delivery frame 322 through the delivery pipe 380. The clean water can pass through the arc groove and fall between the telescopic sleeve 361 and the sampling tube 210, between the sampling tube 210 and the central tube 220, and inside the central tube 220, thereby flushing the sampling tube 210 and the central tube 220. The clean water in the sampling tube 210 and the central tube 220 can fall on the sliding block 230 and the sliding ring 240. The sliding block 230 and the sliding ring 240 are rinsed, and then the rotating frame 320 can be rotated to the original position. At this time, the fixed tube 375 can correspond to the air outlet pipe 378, and then the air pump 376 can be started to make the air pump 376 inhale through the air inlet pipe 377 and deliver air to the fixed tube 375 through the air pump 376. The fixed tube 375 can be inflated to the inside of the delivery frame 322 through the delivery pipe 380, so as to deliver air to the inside of the sampling tube 210 and the central tube 220 to dry the water stains in the sampling tube 210 and the central tube 220, so as to prepare for the next sampling. A hot air blower can be used instead of the air pump 376, so that hot air can be delivered to the inside of the sampling module 200 to speed up the drying of the water stains in the sampling tube 210 and the central tube 220.
