Description

Technical Field

[0001] The present invention belongs to the technical field of particle sampling, and specifically relates to a fertilizer particle sampler for fertilizer production. Background Art

[0002] During the production process of fertilizers, it is necessary to sample fertilizer particles. By sampling and testing, the nutrient content, impurity content, and physical properties in the fertilizers can be understood, so as to ensure that the produced fertilizers meet the established quality standards.

[0003] The patent with the publication number CN109781455B discloses a fertilizer particle sampler for fertilizer production. The lower end of the first spring is fixedly connected to the inner wall of the support frame. The upper end of the support shaft is connected with a support block. A bearing is embedded in the side wall of the support block. One end of the wheel shaft is inserted into the inner ring of the bearing. A roller is fixedly sleeved on the wheel shaft. The outer edge of the roller is in movable contact with the upper surface of the conveyor belt. The other end of the wheel shaft is connected to one end of the sample delivery pipe. A sampling pipe is connected through the side wall of the sample delivery pipe. The other end of the sample delivery pipe is connected to the sampling box in a through manner. The contact between the sample delivery pipe and the sampling box is movably connected through a rolling ball. The sample delivery pipe and the rolling ball are movably inserted. 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 pipe to take samples, which is convenient and fast, without manual sampling, reduces the harm caused by the direct contact of fertilizer particles to the human body, has higher safety, and stronger practicability.

[0004] However, the above technical solution still has the following deficiencies in the actual application process:

[0005] When using the sampling pipe to sample the fertilizer particles transported on the conveyor belt, the samples taken by the sampling pipe are then sent into the sampling box through the sample delivery pipe. However, in some cases, in order to facilitate the transportation of fertilizer particles, the fertilizer particles are loaded into multiple boxes. The boxes move along with the conveyor belt and pass through multiple processes such as sampling in sequence. When using the sampling pipe to sample the fertilizer particles in the box, since the fertilizer particles are distributed at various positions in the box and the sampling pipe can only achieve single-point sampling, it is difficult for the obtained samples to represent the overall quality of the fertilizer particles in the box, thereby affecting the accuracy of the sampling results. Moreover, even if the position of the sampling pipe is changed to perform multi-point sampling, the sampling error may be large due to the random and irregular multiple sampling positions.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. A fertilizer granule sampler for fertilizer production according to the present invention uses a uniformly distributed sampling mechanism. By setting multiple sampling cylinders, and regarding each sampling cylinder as a sampling point, the sampling points can be equidistantly arranged in the box according to the length of the box body, so as to uniformly obtain fertilizer granule samples from various positions of the box body, avoiding the situation that the sample is not representative due to too single sampling orientation, improving the sampling efficiency. Moreover, since the distance between each sampling point is the same, the sampling positions are relatively regular, which is conducive to reducing the sampling error. And before sampling, the fertilizer granules in the box body can be equally divided into multiple parts by multiple partition plates I and partition plates II. The area between two adjacent partition plates I is a sampling area. When the sampling cylinder samples the fertilizer granules at the sampling point, even if the fertilizer granules generate displacement, they will only be in a fixed area and will not move to other sampling points. Thus, after finding a problem sample, the area where the problem sample appears can be accurately locked, which is conducive to further sampling and detection of the fertilizer granules.

[0022] 2. A fertilizer granule sampler for fertilizer production according to the present invention uses a distance adaptation type material taking mechanism. When there are quality problems with the fertilizer granules between two partition plates I, the fertilizer granules in this area can be first taken out separately from the box body and then further detected. This not only avoids the fertilizer granules in this area from entering the next process, but also does not delay the remaining fertilizer granules in the box body from entering the next process when further sampling and detecting the fertilizer granules in the problem area, thereby improving the overall sampling efficiency.

[0038] Please refer to Figures 1 - 12 , the present invention provides a technical solution: A fertilizer granule sampler for fertilizer production, including a support column 1, the upper end of the support column 1 is fixedly connected with a top plate 2, and a uniformly distributed sampling mechanism for sampling fertilizer granules in a box body is arranged on the top plate 2;

A second partition 16 is inserted and slidably connected to the first partition 15.

[0040] In this embodiment, as Figure 1 , Figure 2 , Figures 4 - 6 , Figure 11 , Figure 12 shown, one side of the upper end surface of the top plate 2 is fixedly connected with a fourth electric push rod 50. The piston end of the fourth electric push rod 50 is fixedly connected with a groove plate 20. Both sides of the groove plate 20 are fixedly connected with the adjusting rod 17. A guide plate 21 is slidably connected to the chute of the groove plate 20. A plurality of chutes are arranged on the guide plate 21. The upper end of the slider 18 is fixedly connected with a guide post 19. The guide post 19 passes through the chute on the guide plate 21 and is slidably connected therewith. A fourth threaded rod 52 is threadedly connected to the upper end of the guide plate 21. Both ends of the fourth threaded rod 52 are rotatably arranged on the groove plate 20. One end of the groove plate 20 is fixedly connected with a tenth motor 51. The output end of the tenth motor 51 is fixedly connected with one end of the fourth threaded rod 52.

[0041] One side of the upper end of the first partition 15 is rotatably provided with a fourth connecting rod 30. One end of the fourth connecting rod 30 is rotatably connected with a third connecting rod 29. One end of the third connecting rod 29 is rotatably connected with one end of the second partition 16. One side of the slider 18 is fixedly connected with a second motor 22. The output end of the second motor 22 is fixedly connected with one end of the first connecting rod 23. One side of the upper end of the first partition 15 is fixedly connected with a third motor 28. The output end of the third motor 28 is fixedly connected with one end of the fourth connecting rod 30.

[0042] A clamping assembly for fixing the box containing fertilizer particles is further arranged on the top plate 2;

[0043] The clamping assembly includes clamping rods 7 slidably connected to both sides of the top plate 2. A second bidirectional threaded rod 49 is threadedly connected to the upper ends of the clamping rods 7. Both ends of the second bidirectional threaded rod 49 are rotatably arranged on the top plate 2. One side of the upper end surface of the top plate 2 is fixedly connected with an eighth motor 47. The output end of the eighth motor 47 is fixedly connected with one end of the second bidirectional threaded rod 49.

[0044] 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 sent into the sampling box by the sample delivery tube. However, in some cases, for the convenience of transporting fertilizer particles, the fertilizer particles are loaded into multiple boxes, and the boxes move along with the conveyor belt and pass through multiple processes such as sampling in sequence. When using the sampling tube to sample the fertilizer particles in the box, since the fertilizer particles are distributed at various positions in the box and the sampling tube can only achieve single-point sampling, it is difficult for the obtained sample to represent the overall quality of the fertilizer particles in the box, thereby affecting the accuracy of the sampling result. Moreover, even if the position of the sampling tube is changed to perform multi-point sampling, the sampling error may be large due to the random and irregular positions of multiple sampling points;

[0045] Therefore, to solve the above problems, in the use of this embodiment, the support column 1 is installed beside the conveyor belt. When the box filled with fertilizer particles moves along with the conveyor belt to between the two clamping rods 7, the multiple sampling cylinders 26 just align with the fertilizer particles in the box. At this time, according to the length of the box, by driving the rotation of the threaded rod four 52 by the motor ten 51, the guide plate 21 slides horizontally on the groove plate 20. Since the sliding grooves of the guide plate 21 except for the middle part are in an inclined state, the guide posts 19 except for the middle part will move due to the movement of the guide plate 21, causing the slider 18 to slide on the adjusting rod 17. Moreover, the distance between adjacent sliders 18 always remains the same. Thus, according to the length of the box, the orientation of the multiple sampling cylinders 26 can be adjusted so that the sampling cylinders 26 at both ends are at both ends of the box. At this time, by driving the rotation of the connecting rod one 23 and the connecting rod two 24 by the motor two 22, the adjusting block 25 and the sampling cylinder 26 can be lowered, and the sampling cylinder 26 extends into the fertilizer particles. The fertilizer particles enter the sampling cylinder 26 through the sampling port 27, and then the sampling cylinder 26 is driven to move upward to take out the fertilizer particles. At this time, the worker can detect the fertilizer particles taken out by the sampling cylinder 26. Moreover, each sampling cylinder 26 is regarded as a sampling point, and according to the length of the box, the sampling points can be equidistantly arranged in the box, so that fertilizer particle samples can be uniformly obtained from various positions of the box, avoiding the situation that the sample is not representative due to too single sampling orientation, improving the sampling efficiency. Moreover, since the distance between each sampling point is the same, the sampling positions are relatively regular, which is beneficial to reducing the sampling error;

[0046] Moreover, to ensure the accuracy of the sampling results, it is necessary to repeatedly sample the fertilizer particles in the box with the sampling cylinder 26 multiple times. After discovering a sample with quality problems, further sample and detect the fertilizer particles at the sampling point corresponding to the problem sample. However, each time the sampling cylinder 26 extends into the fertilizer particles, it will cause the displacement of the fertilizer particles. As a result, when further sampling the fertilizer particles at the sampling point corresponding to the problem sample, the situation of moving to other sampling points occurs, which affects the subsequent further sampling and detection work. Therefore, to avoid this situation, when the box moves to between the two clamping rods 7 along with the conveyor belt and the side edge of one side of the box is flush with the side edge of the first partition 15, the two clamping rods 7 can be made to approach each other and clamp the box by driving the rotation of the double-threaded rod two 49 by the motor eight 47. According to the width of the box, the second partition 16 can be made to slide on the first partition 15 by driving the rotation of the connecting rod four 30 and the connecting rod three 29 by the motor three 28 until the distance from one side of the first partition 15 to one side of the second partition 16 is equal to the width of the box, and the distance between adjacent sampling cylinders 26 is also equal to the distance between adjacent second partitions 16. At this time, the adjusting rod 17 can be driven to descend by the electric push rod four 50, so that multiple first partitions 15 and second partitions 16 extend into the box. In this way, the fertilizer particles in the box can be equally divided into multiple parts by the multiple first partitions 15 and second partitions 16. The area between two adjacent first partitions 15 is a sampling area. When the sampling cylinder 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. Thus, after discovering a problem sample, the area where the problem sample appears can be accurately locked, which is conducive to further sampling and detecting the fertilizer particles.

[0047] In this embodiment, as Figures 1 - 4 , Figures 7 - 11 shown, a spacing-adaptive material taking mechanism is further provided on the top plate 2;

[0048] The spacing-adaptive material taking mechanism includes a displacement plate 3 slidably connected to one side of the upper end surface of the top plate 2.

One side of the lower end of the displacement plate 3 is fixedly connected with a fourth motor 33. The output end of the fourth motor 33 is fixedly connected with one end of the third threaded rod 32.

[0050] One side of the upper end surface of the threaded plate 34 is fixedly connected with a second electric push rod 35. The piston end of the second electric push rod 35 is fixedly connected with one side of the upper end surface of the frame 37. One side of the upper end of the transverse moving rod 40 is threadedly connected with a first bidirectional threaded rod 42. Both ends of the first bidirectional threaded rod 42 are rotatably arranged on the frame 37. One side of the frame 37 is fixedly connected with a fifth motor 41. The output end of the fifth motor 41 is fixedly connected with one end of the first bidirectional threaded rod 42.

[0051] One side of the lower end of the transverse moving rod 40 is fixedly connected with a sixth motor 44. The output end of the sixth motor 44 is fixedly connected with one end of the material taking plate 38. One side of the inner cavity of the material taking plate 38 is fixedly connected with a third electric push rod 45. The piston end of the third electric push rod 45 is fixedly connected with one side of the telescopic plate 39.

[0052] One end of the connecting rod 4 is threadedly connected with a second threaded rod 14. Both ends of the second threaded rod 14 are rotatably arranged on the top plate 2. One side of the upper end surface of the top plate 2 is fixedly connected with a seventh motor 46. The output end of the seventh motor 46 is fixedly connected with one end of the second threaded rod 14.

[0053] One end of the lifting plate 10 is threadedly connected with a first threaded rod 9. Both ends of the first threaded rod 9 are rotatably arranged on the connecting rod 4. One side of the upper end of the connecting rod 4 is fixedly connected with a first motor 8. The output end of the first motor 8 is fixedly connected with one end of the first threaded rod 9. One side of the lifting plate 10 is fixedly connected with a first electric push rod 11. The piston end of the first electric push rod 11 is fixedly connected with one end of the second baffle 6.

[0054] Specifically, in the above embodiment, although the inside of the box can be divided into multiple sampling areas by a plurality of partition plates I 15 and partition plates II 16, after the sampling work is completed, the partition plates I 15 and partition plates II 16 will still be removed from the box, and the box will continue to move with the conveyor belt to the next process. When there are quality problems with the fertilizer particles in a certain sampling area, the fertilizer particles in this area will still be mixed with the fertilizer particles in the other areas due to the removal of the partition plates I 15 and partition plates II 16, resulting in the fertilizer particles with quality problems entering the next process, thereby affecting the quality of the subsequent fertilizer. Moreover, since it is necessary to sample the fertilizer particles in the problem area multiple times, the box needs to stay at the designated position on the conveyor belt all the time, thus delaying the entry of the fertilizer particles in the other areas into the next process. Therefore, to avoid the above situation, when the box stops on the conveyor belt during the use of this embodiment, one side of the box is also flush with one side of the baffle I 5. When there are quality problems with the fertilizer particles in a certain sampling area, the position of the frame body 37 in the X, Y, and Z axis directions is adjusted by driving the rotation of the threaded rod V 12 by the motor IX 48, driving the rotation of the threaded rod III 32 by the motor IV 33, and the telescopic movement of the piston end of the electric push rod II 35. Then, according to the width of the sampling area, the distance between the two cross rods 40 is adjusted by driving the rotation of the bidirectional threaded rod I 42 by the motor V 41, so that the two material taking plates 38 can extend into the problem sampling area, and the material taking plate 38 is attached to the partition plate I 15. Moreover, by driving the sliding of the telescopic plate 39 on the material taking plate 38 by the electric push rod III 45, both sides of the material taking plate 38 and the telescopic plate 39 can be attached to the inner wall of the box until the bottom of the material taking plate 38 and the telescopic plate 39 is attached to the bottom of the box. Then, the two motors VI 44 on both sides drive the two material taking plates 38 to rotate simultaneously and in different directions. During the rotation of the material taking plate 38, its bottom is always attached to the bottom of the box until the material taking plate 38 and the telescopic plate 39 rotate 90 degrees. At this time, the material taking plate 38 and the telescopic plate 39 hold up some of the fertilizer particles, and then the material taking plate 38 is driven to move upward, so that the fertilizer particles can rise. When the fertilizer particles are about to cross the upper edge of the box, according to the width of the box, the distance between the baffle I 5 and the baffle II 6 can be adjusted by driving the sliding of the baffle II 6 on the lifting plate 10 by the electric push rod I 11, and the height of the lifting plate 10 can be adjusted under the action of driving the rotation of the threaded rod I 9 by the motor I 8. At this time, the ends of the baffle I 5 and the baffle II 6 are both aligned with the upper edge of the box. Then, the connecting rod 4 is slid on the top plate 2 by driving the rotation of the threaded rod II 14 by the motor VII 46 until the baffle I 5 and the baffle II 6 block the upper edge of the box. When the fertilizer particles on the material taking plate 38 and the telescopic plate 39 are higher than the upper edge of the box, they will also be surrounded by the partition plate I 15, the partition plate II 16, the baffle I 5, and the baffle II 6 and will not fall onto the conveyor belt. At this time, a collection container can be placed below the material taking plate 38 to make the fertilizer particles on the material taking plate 38 fall into the collection container, thus realizing the separate collection of the fertilizer particles in the problem area, not only avoiding the entry of the fertilizer particles in this area into the next process,When further sampling and testing the fertilizer particles in the problem area, it is also possible to allow the remaining fertilizer particles in the box to enter the next process without delay, improving the overall sampling efficiency.

[0055] Working principle: Install the support column 1 beside the conveyor belt. When the box containing fertilizer particles moves to between the two clamping rods 7 along with the conveyor belt, the multiple sampling cylinders 26 are just aligned with the fertilizer particles in the box. At this time, according to the length of the box, drive the threaded rod four 52 to rotate by the motor ten 51, so that the guide plate 21 slides horizontally on the groove plate 20. Since the sliding grooves of the guide plate 21 except the middle part are in an inclined state, the guide posts 19 except the middle part will move due to the movement of the guide plate 21, causing the slider 18 to slide on the adjusting rod 17. And the distance between adjacent sliders 18 always remains the same. Then, according to the length of the box, the orientation of the multiple sampling cylinders 26 can be adjusted so that the sampling cylinders 26 at both ends are located at both ends of the box. At this time, drive the connecting rod one 23 to rotate (i.e., the connecting rod two 24 rotates) by the motor two 22, and the adjusting block 25 and the sampling cylinder 26 can be lowered, and the sampling cylinder 26 extends into the fertilizer particles. The fertilizer particles enter the sampling cylinder 26 through the sampling port 27, and then drive the sampling cylinder 26 to move upward to take out the fertilizer particles. At this time, the work can detect the fertilizer particles taken out by the sampling cylinder 26. And each sampling cylinder 26 is regarded as a sampling point. Then, according to the length of the box, the sampling points can be equidistantly set in the box, so that fertilizer particle samples can be uniformly obtained from various positions of the box, avoiding the situation that the sample is not representative due to too single sampling orientation, improving the sampling efficiency. And because the distance between each sampling point is the same, the sampling positions are relatively regular, which is beneficial to reducing the sampling error. And in order to ensure the accuracy of the sampling result, it is necessary to make the sampling cylinder 26 sample the fertilizer particles in the box repeatedly for many times. And after finding a sample with quality problems, further sample and detect the fertilizer particles corresponding to the sampling point of the problem sample in time. However, every time the sampling cylinder 26 extends into the fertilizer particles, it will cause the displacement of the fertilizer particles, resulting in the situation that the fertilizer particles corresponding to the sampling point of the problem sample move to other sampling points during further sampling, thus affecting the subsequent further sampling and detection work. Therefore, to avoid this situation, when the box moves to between the two clamping rods 7 along with the conveyor belt and the side edge of one side of the box is flush with the side edge of the partition one 15, drive the bidirectional threaded rod two 49 to rotate by the motor eight 47, so that the two clamping rods 7 approach each other to clamp the box. And according to the width of the box, drive the connecting rod four 30 and the connecting rod three 29 to rotate by the motor three 28, so that the partition two 16 slides on the partition one 15 until the distance from one side of the partition one 15 to one side of the partition two 16 is equal to the width of the box, and the distance between adjacent sampling cylinders 26 is also equal to the distance between adjacent partition two 16s. At this time, drive the adjusting rod 17 to lower by the electric push rod four 50, so that the multiple partition one 15s and partition two 16s extend into the box, and the fertilizer particles in the box can be equally divided into multiple parts by the multiple partition one 15s and partition two 16s. The area between two adjacent partition one 15s is a sampling area. When the sampling cylinder 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 a problem sample is found, the area where the problem sample appears can be accurately locked, which is conducive to further sampling and detection of the fertilizer particles. When the box stops on the conveyor belt, one side of the box is also flush with one side of the baffle 5. When there are quality problems with the fertilizer particles in a certain sampling area, the position of the frame 37 in the X, Y, and Z axis directions is adjusted by driving the rotation of the threaded rod five 12 by the motor nine 48, driving the rotation of the threaded rod three 32 by the motor four 33, and the telescopic movement of the piston end of the electric push rod two 35. Then, according to the width of the sampling area, the distance between the two cross rods 40 is adjusted by driving the rotation of the bidirectional threaded rod one 42 by the motor five 41, so that the two material taking plates 38 can extend into the problem sampling area, and the material taking plate 38 is attached to the partition one 15. Moreover, by driving the sliding of the telescopic plate 39 on the material taking plate 38 by the electric push rod three 45, one side of the material taking plate 38 and the telescopic plate 39 can be attached to the inner wall of the box until the bottom of the material taking plate 38 and the telescopic plate 39 is attached to the bottom of the box. Then, the two motors six 44 on both sides drive the two material taking plates 38 to rotate simultaneously in different directions. Moreover, during the rotation of the material taking plate 38, its bottom is always attached to the bottom of the box until the material taking plate 38 and the telescopic plate 39 rotate 90 degrees. At this time, the material taking plate 38 and the telescopic plate 39 hold up some fertilizer particles, and then the material taking plate 38 is driven to move upward, so that the fertilizer particles can rise. When the fertilizer particles are about to cross the upper edge of the box, according to the width of the box, the electric push rod one 11 is used to drive the baffle two 6 to slide on the lifting plate 10, adjust the distance between the baffle one 5 and the baffle two 6, and under the action of driving the rotation of the threaded rod one 9 by the motor one 8, adjust the height of the lifting plate 10. At this time, the ends of the baffle one 5 and the baffle two 6 are both aligned with the upper edge of the box. Then, the connecting rod 4 is slid on the top plate 2 by driving the rotation of the threaded rod two 14 by the motor seven 46 until the baffle one 5 and the baffle two 6 block the upper edge of the box. When the fertilizer particles on the material taking plate 38 and the telescopic plate 39 are higher than the upper edge of the box, they will also be surrounded by the partition one 15, the partition two 16, the baffle one 5, and the baffle two 6 and will not fall onto the conveyor belt. At this time, a collection container can be placed below the material taking plate 38 to make the fertilizer particles on the material taking plate 38 fall into the collection container, thus realizing the separate collection of the fertilizer particles in the problem area. This not only avoids the fertilizer particles in this area from entering the next process, but also does not delay the remaining fertilizer particles in the box from entering the next process when further sampling and detecting the fertilizer particles in the problem area, improving the overall sampling efficiency.
