Description

Technical Field

[0001] The invention belongs to the technical field of particle sampling, in particular to a fertilizer particle sampler for fertilizer production. Background Art

[0002] During the production process of fertilizers, it is necessary to sample the fertilizer particles. Through sampling and testing, we can understand the nutrient content, impurity content and physical properties of the fertilizers, thereby ensuring that the produced fertilizers meet the established quality standards.

[0003] The patent with announcement number CN109781455B discloses a fertilizer particle sampler for fertilizer production, wherein the lower end of a spring No. 1 is connected and fixed to the inner wall of a support frame, the upper end of a support shaft is connected to a support block, a bearing is embedded in the side wall of the support block, one end of a wheel shaft is inserted into the inner ring of the bearing, a roller is sleeved and fixed on the wheel shaft, the outer edge of the roller is movably contacted with the upper surface of a conveyor belt, the other end of the wheel shaft is connected to one end of a sample delivery tube, a sampling tube is connected through the side wall of the sample delivery tube, the other end of the sample delivery tube is connected through the sampling box, the contact point between the sample delivery tube and the sampling box is movably connected through a rolling ball, the sample delivery tube and the rolling ball are movably inserted, and the rolling ball is movably embedded in the rolling ball groove in the rear wall of the sampling box. It uses the operation of the finished product conveyor belt to provide power to drive the sampling tube for sampling, which is convenient and fast, does not require manual sampling, reduces the harm caused by direct contact of fertilizer particles to the human body, is safer, and is more practical.

[0004] However, the above technical solution still has the following deficiencies in practical application: The fertilizer particles transported on the conveyor belt are sampled by a sampling tube, and the samples taken by the sampling tube are then sent into a sampling box by a sample delivery tube. However, in some cases, in order to facilitate the transportation of the fertilizer particles, the fertilizer particles are loaded into multiple boxes, and the boxes move with the conveyor belt and sequentially go through multiple processes such as sampling. When the fertilizer particles in the box are sampled by a sampling tube, since the fertilizer particles are distributed at various positions in the box and the sampling tube can only achieve single-point sampling, the sample obtained is difficult to represent the overall quality of the fertilizer particles in the box, thereby affecting the accuracy of the sampling results. Moreover, even if multi-point sampling is performed by changing the position of the sampling tube, the sampling error may be large due to the randomness and irregularity of the multiple sampling positions.

Moreover, since the spacing between each sampling point is the same, the sampling position is relatively regular, which is beneficial to reducing the sampling error. Moreover, before sampling, the fertilizer particles in the box can be equidistantly divided into multiple parts by using a plurality of partitions 1 and 2, and a sampling area is formed between two adjacent partitions 1. When the sampling barrel samples the fertilizer particles at the sampling point, even if the fertilizer particles are displaced, they will only be in a fixed area and will not move to other sampling points.

When the fertilizer particles between two partitions have quality problems, the fertilizer particles in this area can be taken out from the box separately and then further tested. This not only prevents the fertilizer particles in this area from entering the next process, but also allows the fertilizer particles in the problem area to be further sampled and tested without delaying the remaining fertilizer particles in the box from entering the next process, thereby improving the overall sampling efficiency.

Both sides of the slot plate 20 are fixedly connected to the adjusting rod 17. The slot plate 20 is slidably connected to the guide plate 21, and a plurality of slots are arranged on the guide plate 21. The upper end of the slider 18 is fixedly connected to the guide column 19, and the guide column 19 passes through the slot on the guide plate 21 and is slidably connected thereto. The upper end of the guide plate 21 is threadedly connected to a threaded rod four 52, and both ends of the threaded rod four 52 are rotatably arranged on the slot plate 20. One end of the slot plate 20 is fixedly connected to a motor ten 51, and the output end of the motor ten 51 is fixedly connected to one end of the threaded rod four 52.

[0025] The top plate 2 is also provided with a clamping assembly for fixing the box containing the fertilizer particles; The clamping assembly includes a clamping rod 7 slidably connected to both sides of the top plate 2, the upper end of the clamping rod 7 is threadedly connected to a bidirectional threaded rod 49, both ends of the bidirectional threaded rod 49 are rotatably set on the top plate 2, and a motor 8 47 is fixedly connected to one side of the upper end surface of the top plate 2, and the output end of the motor 8 47 is fixedly connected to one end of the bidirectional threaded rod 49.

[0026] Specifically, in the prior art, a sampling tube is used to sample the fertilizer particles transported on the conveyor belt, and the sample taken by the sampling tube is then sent into the sampling box by the sample delivery tube. However, in some cases, in order to facilitate the transportation of the fertilizer particles, the fertilizer particles are loaded into multiple boxes, and the boxes move with the conveyor belt and sequentially go through multiple processes such as sampling. When the fertilizer particles in the box are sampled by the sampling tube, since the fertilizer particles are distributed at various positions in the box and the sampling tube can only achieve single-point sampling, the sample taken is difficult to represent the overall quality of the fertilizer particles in the box, thereby affecting the accuracy of the sampling result. Moreover, even if multi-point sampling is performed by changing the position of the sampling tube, the sampling error may be large because the multiple sampling positions are relatively random and irregular. Therefore, in order to solve the above-mentioned problem, when the present embodiment is in use, the pillar 1 is installed beside the conveyor belt. When the box body filled with fertilizer particles follows the conveyor belt and moves between the two clamping rods 7, the multiple sampling barrels 26 are just aligned with the fertilizer particles in the box body. At this time, according to the length of the box body, the motor 10 51 drives the threaded rod 24 52 to rotate, so that the guide plate 21 slides horizontally on the groove plate 20. Since the slide grooves of the guide plate 21 except the middle part are all in an inclined state, the guide columns 19 except the middle part will move due to the movement of the guide plate 21, so that the slider 18 slides on the adjusting rod 17, and the spacing between adjacent sliders 18 always remains the same. The orientation of the multiple sampling barrels 26 can be adjusted according to the length of the box body, so that the sampling barrels 26 at both ends are at the two ends of the box body. At this time, the electric The second machine 22 drives the connecting rod 1 23 to rotate, that is, the second connecting rod 24 rotates, so that the adjustment block 25 and the sampling tube 26 can be lowered, and the sampling tube 26 extends into the fertilizer particles, and the fertilizer particles enter the sampling tube 26 through the sampling port 27, and then the sampling tube 26 is driven to move upward to take out the fertilizer particles. At this time, the fertilizer particles taken out by the sampling tube 26 can be tested, and each sampling tube 26 is regarded as a sampling point, that is, the sampling points can be equidistantly arranged in the box according to the length of the box, so that the fertilizer particle samples can be uniformly obtained from various positions of the box, avoiding the situation that the samples are not representative due to the sampling orientation being too single, improving the sampling efficiency, and because the spacing between each sampling point is the same, the sampling position is more regular, which is conducive to reducing the sampling error; Furthermore, in order to ensure the accuracy of the sampling results, it is necessary to make the sampling barrel 26 repeatedly sample the fertilizer particles in the box, and after finding samples with quality problems, further sample and test the fertilizer particles at the sampling points corresponding to the problematic samples in a timely manner. Since each time the sampling barrel 26 is inserted into the fertilizer particles, the fertilizer particles will be displaced, which will cause the fertilizer particles at the sampling points corresponding to the problematic samples to move to other sampling points during further sampling, thereby affecting the subsequent further sampling and testing work. Therefore, in order to avoid this situation, when the box moves with the conveyor belt to between the two clamping rods 7 and the edge of one side of the box is flush with the edge of one side of the partition 15, the motor 8 47 can be used to drive the bidirectional threaded rod 2 49 to rotate, so that the two clamping rods 7 are brought closer to each other to clamp the box, and according to the width of the box, the motor 3 2 8 drives the connecting rod four 30 and the connecting rod three 29 to rotate, so that the partition two 16 slides on the partition one 15 until the distance from the side of the partition one 15 to the side of the partition two 16 is equal to the width of the box, and the spacing between adjacent sampling tubes 26 is also equal to the spacing between adjacent partition two 16. At this time, the electric push rod four 50 can be used to drive the adjusting rod 17 to descend, so that multiple partitions one 15 and partition two 16 can be extended into the box, and the fertilizer particles in the box can be divided into multiple parts with equal distance through multiple partitions one 15 and partition two 16. A sampling area is between two adjacent partitions one 15. When the sampling tube 26 samples the fertilizer particles at the sampling point, even if the fertilizer particles are displaced, they will only be in a fixed area and will not move to other sampling points. Therefore, after the problem sample is found, the problem sample area can be accurately locked, which is conducive to further sampling and detection of the fertilizer particles.

A bidirectional threaded rod 1 42 is threadedly connected to one side of the upper end of the transverse rod 40, and both ends of the bidirectional threaded rod 1 42 are rotatably set on the frame 37. A motor 5 41 is fixedly connected to one side of the frame 37, and the output end of the motor 5 41 is fixedly connected to one end of the bidirectional threaded rod 1 42.

[0030] A motor 6 44 is fixedly connected to one side of the lower end of the transverse rod 40, and the output end of the motor 6 44 is fixedly connected to one end of the material picking plate 38. An electric push rod 3 45 is fixedly connected to one side of the inner cavity of the material picking plate 38, and the piston end of the electric push rod 3 45 is fixedly connected to one side of the telescopic plate 39.

[0031] One end of the connecting rod 4 is threadedly connected to the threaded rod 2 14 , and both ends of the threaded rod 2 14 are rotatably set on the top plate 2 , and one side of the upper end surface of the top plate 2 is fixedly connected to the motor 7 46 , and the output end of the motor 7 46 is fixedly connected to one end of the threaded rod 2 14 .

[0033] Specifically, in the above embodiment, although the interior of the box body can be divided into multiple sampling areas by multiple partitions 15 and partitions 2 16, after the sampling work is completed, the partitions 15 and 16 will still be removed from the box body, and the box body will continue to follow the conveyor belt to move to the next process. When the fertilizer particles in a certain sampling area have quality problems, the fertilizer particles in this area will still be mixed with the fertilizer particles in other areas due to the removal of the partitions 15 and 16, thereby causing the fertilizer particles with quality problems to enter the next process, thereby affecting the quality of subsequent fertilizers. In addition, since it is necessary to sample the fertilizer particles in the problem area multiple times, the box body needs to always stay at the specified position of the conveyor belt, thereby delaying the fertilizer particles in other areas from entering the next process. Therefore, in order to avoid the above situation, when the box body is in use, one side of the box body is also flush with one side of the baffle plate 15. When the fertilizer particles in a certain sampling area have quality problems, the motor 9 48 drives the threaded rod 5 12 to rotate, the motor 4 33 drives the threaded rod 3 32 to rotate, and the piston end of the electric push rod 2 35 is extended and retracted to adjust the position of the frame 37 in the X, Y, and Z axis directions. Then, according to the width of the sampling area, the motor 5 41 drives the bidirectional threaded rod 1 42 to rotate, and the spacing between the two transverse rods 40 is adjusted, so that the two feeding plates 38 can extend into the problematic sampling area, and the feeding plates 38 are fitted with the partition plate 15. In addition, the electric push rod 3 45 drives the telescopic plate 39 to slide on the feeding plate 38. , so that one side of the feeding plate 38 and the telescopic plate 39 can be fitted with the inner wall of the box, until the bottom of the feeding plate 38 and the telescopic plate 39 are fitted with the bottom of the box, and then the motors 64 on both sides simultaneously drive the two feeding plates 38 to rotate in different directions, and during the rotation of the feeding plate 38, its bottom is always fitted with the bottom of the box, until the feeding plate 38 and the telescopic plate 39 rotate ninety degrees. At this time, the feeding plate 38 and the telescopic plate 39 hold part of the fertilizer particles, and then drive the feeding plate 38 to move upward, so that the fertilizer particles can rise. When the fertilizer particles are about to cross the upper edge of the box, the electric push rod 11 can be used to drive the baffle 26 to slide on the lifting plate 10 according to the width of the box, and the distance between the baffle 15 and the baffle 26 can be adjusted, and the motor 18 drives the screw Under the action of the rotation of the threaded rod 19, the height of the lifting plate 10 is adjusted. At this time, the ends of the baffle 15 and the baffle 26 are aligned with the upper edge of the box body, and then the motor 7 46 drives the threaded rod 214 to rotate to make the connecting rod 4 slide on the top plate 2 until the baffle 15 and the baffle 26 block the upper edge of the box body. When the fertilizer particles on the feeding plate 38 and the telescopic plate 39 are higher than the upper edge of the box body, they will also be blocked by the partition 15, the partition 2 16, the baffle 15, and the baffle 26 and will not fall onto the conveyor belt. At this time, a collection container can be placed under the feeding plate 38 to make the fertilizer particles on the feeding plate 38 fall into the collection container, thereby realizing the separate collection of the fertilizer particles in the problem area, which not only prevents the fertilizer particles in this area from entering the next process,It can also be used to further sample and test the fertilizer particles in the problem area without delaying the remaining fertilizer particles in the box from entering the next process, thus improving the overall sampling efficiency.

[0034] Working principle: The support column 1 is installed beside the conveyor belt. When the box filled with fertilizer particles follows the conveyor belt and moves between the two clamping rods 7, the multiple sampling barrels 26 are just aligned with the fertilizer particles in the box. At this time, according to the length of the box, the motor 10 51 drives the threaded rod 4 52 to rotate, so that the guide plate 21 slides horizontally on the groove plate 20. Since the slide grooves of the guide plate 21 except the middle part are all in an inclined state, the guide column 19 except the middle part will move due to the movement of the guide plate 21, so that the slider 18 slides on the adjustment rod 17, and the spacing between adjacent sliders 18 always remains the same. The orientation of the multiple sampling barrels 26 can be adjusted according to the length of the box, so that the sampling barrels 26 at both ends are at the two ends of the box. At this time, the motor 22 The connecting rod 1 23 is driven to rotate, that is, the connecting rod 24 is rotated, so that the adjustment block 25 and the sampling tube 26 can be lowered, and the sampling tube 26 is extended into the fertilizer particles. The fertilizer particles enter the sampling tube 26 through the sampling port 27, and then the sampling tube 26 is driven to move upward to take out the fertilizer particles. At this time, the fertilizer particles taken out by the sampling tube 26 can be tested, and each sampling tube 26 is regarded as a sampling point, that is, the sampling points can be equidistantly arranged in the box according to the length of the box, so that the fertilizer particle samples can be evenly obtained from various positions of the box, avoiding the situation that the samples are not representative due to the sampling orientation being too single, and improving the sampling efficiency. Moreover, since the spacing between each sampling point is the same, the sampling position is more regular, which is beneficial to Reduce sampling errors; and, in order to ensure the accuracy of the sampling results, it is necessary to make the sampling barrel 26 repeatedly sample the fertilizer particles in the box, and after discovering samples with quality problems, further sample and test the fertilizer particles at the sampling points corresponding to the problem samples in a timely manner. However, each time the sampling barrel 26 is extended into the fertilizer particles, the fertilizer particles will be displaced, which will cause the fertilizer particles at the sampling points corresponding to the problem samples to move to other sampling points during further sampling, thereby affecting the subsequent further sampling and testing work. Therefore, in order to avoid this situation, when the box moves between the two clamping rods 7 with the conveyor belt, and the edge of one side of the box is flush with the edge of one side of the partition 15, the motor 8 47 can be used to drive the bidirectional screw The two clamping rods 7 are brought closer to each other by rotating the grooved rod 2 49 to clamp the box body, and according to the width of the box body, the motor 3 28 drives the connecting rod 4 30 and the connecting rod 3 29 to rotate, so that the partition 2 16 slides on the partition 1 15 until the distance from one side of the partition 15 to the other side of the partition 2 16 is equal to the width of the box body, and the spacing between adjacent sampling barrels 26 is also equal to the spacing between adjacent partitions 2 16. At this time, the electric push rod 4 50 can be used to drive the adjusting rod 17 to descend, so that multiple partitions 15 and partitions 2 16 can be extended into the box body, and the fertilizer particles in the box body can be divided into multiple parts with equal distance through multiple partitions 15 and partitions 2 16. The space between two adjacent partitions 15 is a sampling area. When the sampling barrel 26 samples the fertilizer particles at the sampling point,Even if the fertilizer particles are displaced, they will only be in a fixed area and will not move to other sampling points. Therefore, after the problem sample is found, the area where the problem sample appears can be accurately locked, which is conducive to further sampling and testing of the fertilizer particles. When the box body stops on the conveyor belt, one side of the box body is also flush with the side of the baffle 1 5. When the fertilizer particles in a certain sampling area have quality problems, the motor 9 48 drives the threaded rod 5 12 to rotate, the motor 4 33 drives the threaded rod 3 32 to rotate, and the piston end of the electric push rod 2 35 is extended and retracted to adjust the position of the frame 37 in the X, Y, and Z axis directions, and then according to the width of the sampling area, the motor 5 41 drives the threaded rod 3 32 to rotate. The bidirectional threaded rod 42 is rotated to adjust the spacing between the two transverse rods 40, so that the two feeding plates 38 can extend into the problematic sampling area, and the feeding plates 38 are fitted with the partition 15, and the electric push rod 34 drives the telescopic plate 39 to slide on the feeding plate 38, so that one side of the feeding plate 38 and the telescopic plate 39 can fit with the inner wall of the box until the bottom of the feeding plate 38 and the telescopic plate 39 fit with the bottom of the box, and then the motors 64 on both sides simultaneously drive the two feeding plates 38 to rotate in different directions, and during the rotation of the feeding plate 38, its bottom is always fitted with the bottom of the box until the feeding plate 38 and the telescopic plate 39 rotate ninety degrees. At this time, the feeding plate 38 and the telescopic plate 39 hold part of the fertilizer particles, and then the feeding plate 38 is driven to move upward to make the fertilizer particles rise. When the fertilizer particles are about to cross the upper edge of the box body, the electric push rod 11 can be used to drive the baffle 26 to slide on the lifting plate 10 according to the width of the box body, and the distance between the baffle 15 and the baffle 26 can be adjusted. Under the action of the motor 18 driving the threaded rod 19 to rotate, the height of the lifting plate 10 is adjusted. At this time, the ends of the baffle 15 and the baffle 26 are aligned with the upper edge of the box body, and then the motor 7 46 drives the threaded rod 214 to rotate to make the connecting rod 4 slide on the top plate 2 until the baffle 1 5 and baffle 2 6 block the upper edge of the box. When the fertilizer particles on the material-retrieving plate 38 and the telescopic plate 39 are higher than the upper edge of the box, they will also be blocked by the partition 15, the partition 2 16, the baffle 1 5, and the baffle 2 6 and will not fall onto the conveyor belt. At this time, a collection container can be placed under the material-retrieving plate 38 to make the fertilizer particles on the material-retrieving plate 38 fall into the collection container, thereby realizing the separate collection of the fertilizer particles in the problem area, which not only prevents the fertilizer particles in this area from entering the next process, but also allows the fertilizer particles in the problem area to be further sampled and tested without delaying the remaining fertilizer particles in the box from entering the next process, thereby improving the overall sampling efficiency.
