Description

Technical Field

[0001] This invention relates to the field of fertilizer testing equipment, specifically to a sampling and testing method and apparatus for pearl fertilizer production. Background Technology

[0002] In the fertilizer production process, fertilizer quality testing is an essential step. During testing and sampling, samples need to be randomly obtained from the fertilizer on the conveyor belt. In the fertilizer production process, fertilizer sampling on the conveyor belt should be carried out in segments to ensure that the samples are representative. Most existing sampling machines are segmented or continuous sampling machines, which cannot achieve quantitative analysis and sorting of fertilizer after sampling.

[0003] According to a patent document with publication number CN220690495U, a fertilizer production sampling device includes a base and a screening assembly. A feed channel is fixedly connected to the top outer wall of the base. The screening assembly includes a guide block, a fixing block, a motor, connecting rod one, connecting rod two, a slider, connecting rod three, a screening plate one, a sieve hole one, a screening plate two, a sieve hole two, and a spring. The guide block and the fixing block are fixedly connected to the bottom inner wall of the base. The motor is slidably connected to the side inner wall of the fixing block. The above technical solution, when in use, achieves automatic screening of fertilizer particles of appropriate size and proper storage through the guidance of screening plate one, screening plate two and guide block in the screening component, in conjunction with the vibration driven by the motor and the cooperation of the collection component, for subsequent analysis and testing. Regarding the above technical solution, although it achieves the screening of fertilizer particles, it cannot perform quantitative screening, cannot guarantee that the particles move at a uniform speed through the sieve holes during the screening process, and cannot effectively avoid clogging of the sieve holes during screening, which is inconvenient to use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a sampling and testing method and apparatus for pearl fertilizer production, thereby solving the problems mentioned in the background art. The present invention has a novel structure. In use, the rotating column moves upward in the later stage, and the conical seat enters the interior of the feeding hopper. The feeding depth of the feeding hopper is adjusted by the height of the rising conical seat, thus completing the initial quantitative feeding. In addition, the conical seat and the protrusion can cooperate to push the feeding hopper upward. The rising of the feeding hopper facilitates sampling of fertilizer at higher positions. When the feeding hopper loses the support of the conical seat, it can retract into the box body, reducing the space occupied.

[0005] To achieve the above objectives, the present invention provides a sampling and testing method for pearl fertilizer production, comprising the following steps:

[0006] Step 1: Fertilizer granulation. Solid fertilizer is granulated using fertilizer processing equipment to facilitate subsequent processing.

[0007] Step 2: Pellet drying. After the fertilizer is made into granules, it is dried and shaped inside the drying equipment.

[0008] Step 3: Particle conveying. After drying, the particles are conveyed onto a conveyor belt.

[0009] Step 4: Material sampling and screening. During the granule conveying process, samples of the granular fertilizer on the conveyor belt are randomly taken through containers.

[0010] Step 5: Classification and detection. The particles are introduced into the sorting equipment for sorting, and the particles of different sizes are classified and detected through sorting.

[0011] Furthermore, the process of steps one to five is repeated every 10-15 minutes, and the entire hourly cycle is completed, thereby completing the sampling and detection of particles.

[0012] The sampling device used in the sampling and testing method for pearl fertilizer production as described in claim 1 includes a sorting device. The sorting device includes a box body, a fixed box is fixed to the bottom of the box body, a displacement mechanism is fixedly installed inside the fixed box, a fixed frame is fixed to one end of the displacement mechanism, a drive motor is fixedly installed on the fixed frame, a rotating column is fixed to the drive motor, a rotating disk and a support seat are respectively installed on the rotating column, the rotating disk is welded to the rotating column, the support seat is movably installed on the rotating column, and the rotating disk and the support seat are movably installed inside the box body.

[0013] Furthermore, a movable plate is movably installed on the side of the box, a handle is welded on the movable plate, a discharge port is opened on the box, the discharge port cooperates with the movable plate, a slider is welded on the inner wall of the movable plate, a sliding groove is opened on the box, and the slider is movably installed inside the sliding groove.

[0015] Furthermore, a lifting mechanism is fixed to the top of the box, and a ring seat is fixed to one end of the lifting mechanism. The ring seat is movably installed inside the box, and a fixing rod is welded to the inner wall of the ring seat. The ring seat and the fixing rod cooperate with the rotating disk.

[0016] Furthermore, a friction seat is fixed between the rotating disk and the rotating column, and the friction seat is in movable contact with the support seat. A support ring is fixed on the inner wall of the box, and a rotating ring is rotatably mounted on the support ring. The rotating ring is in movable contact with the bottom of the support seat. A conical seat is fixed on the top of the rotating column, and a partition plate is welded on the support seat.

[0017] Furthermore, the rotating disk has mounting holes, and a filter seat is movably installed inside the mounting holes. The filter seat is installed on the rotating disk by fixing bolts, and a motor box is fixedly installed on the side of the housing.

[0018] Furthermore, a fixing plate is fixed inside the motor housing, a fixing pipe is fixedly installed on the fixing plate, a fan is fixedly installed inside the fixing pipe, a pushing mechanism is installed at a height on the fixing plate, and a movable disc is fixed at one end of the pushing mechanism.

[0020] The beneficial effects of this invention are:

[0021] 1. This sampling and testing device for pearl fertilizer production, in the later stage of use, the rotating column moves upward, and the conical seat enters the interior of the feeding hopper. The feeding depth of the feeding hopper is adjusted by the height of the rising conical seat, thereby completing the initial quantitative feeding. In addition, the conical seat and the protrusion can cooperate to push the feeding hopper upward. The rising of the feeding hopper facilitates sampling of fertilizer at high positions. When the feeding hopper loses the support of the conical seat, it can retract into the box body, reducing the space occupied.

[0022] 2. This sampling and testing device for pearl fertilizer production involves a movable tube moving inward to the bottom of a rotating disc. The rotating disc then rotates, causing the fertilizer to move and come into contact with a fixed rod for stirring. The stirred particles can then quickly and evenly pass through a filter seat for filtration. After the filter seat passes the top of the air blower, the air blower blows upward to remove the particles clogging the filter seat. The air blower and the fixed rod work together to achieve dual cleaning and filtration of the filter seat.

[0023] 3. This sampling and testing device for pearl fertilizer production involves opening the maintenance panel on the housing, disassembling the filter seat and replacing it with filter plates of different pore sizes, moving the rotating disk downwards to bring the friction seat into contact with the support seat, and then rotating the rotating disk 90 degrees through the friction seat to change the position of the partition plate. Later, the friction seat and the support seat cooperate to drive the support seat to rotate as a whole. After the support seat rotates, centrifugal force is used to quickly throw the particles between the partition plates outwards for material collection. Attached Figure Description

[0035] Step 1: Fertilizer granulation. Solid fertilizer is granulated using fertilizer processing equipment to facilitate subsequent processing.

On the rotating column 8, the rotating disk 7 and the support base 14 are movably installed inside the box 1. A movable plate 2 is movably installed on the side of the box 1. A handle 4 is welded on the movable plate 2. A discharge port is opened on the box 1. The discharge port cooperates with the movable plate 2. A slider is welded on the inner wall of the movable plate 2. A sliding groove is opened on the box 1. The slider is movably installed inside the sliding groove. The displacement mechanism 19 is a linear reciprocating electric push rod. The displacement mechanism 19 drives the drive motor 21 on the fixed frame 20 to move up and down. The up and down movement of the drive motor 21 adjusts the height of the rotating disk 7 through the rotating column 8.

[0041] In this embodiment, an installation pipe 30 is fixed to the top of the housing 1. A feeding hopper 6 is movably installed inside the installation pipe 30. A protrusion 29 is fixed on the inner wall of the feeding hopper 6. A limiting groove 31 is opened on the inner wall of the installation pipe 30. A limiting block 32 is movably installed inside the limiting groove 31. One end of the limiting block 32 is fixed to the feeding hopper 6. A support mechanism 33 is fixed between the limiting block 32 and the limiting groove 31. A lifting mechanism 5 is fixed to the top of the housing 1. The lifting mechanism 5 is a linear reciprocating electric push rod. The lifting mechanism 5 pushes the ring seat 11 to move downward. After the ring seat 11 contacts the rotating disk 7, it completes the blocking of fertilizer mixing through the fixing rod 12. The lifting mechanism 5... One end is fixed with a ring seat 11, which is movably installed inside the box body 1. A fixing rod 12 is welded to the inner wall of the ring seat 11. The ring seat 11 and the fixing rod 12 cooperate with the rotating disk 7. A friction seat 13 is fixed between the rotating disk 7 and the rotating column 8. The friction seat 13 is movably in contact with the support seat 14. A support ring 16 is fixed to the inner wall of the box body 1. A rotating ring 17 is rotatably installed on the support ring 16. The rotating ring 17 is movably in contact with the bottom of the support seat 14. A conical seat 9 is fixed to the top of the rotating column 8. A partition plate 15 is welded to the support seat 14. Particles filtered by the filter seat 10 fall directly between the partition plates 15 for storage.

[0042] In this embodiment, the rotating disk 7 has mounting holes, and a filter seat 10 is movably installed inside the mounting holes. The filter seat 10 is installed on the rotating disk 7 by fixing bolts. A motor housing 3 is fixedly installed on the side of the housing 1. A fixing plate 22 is fixedly installed inside the motor housing 3. A fixing pipe 24 is fixedly installed on the fixing plate 22. A fan 25 is fixedly installed inside the fixing pipe 24. A pushing mechanism 23 is installed at a height on the fixing plate 22. The pushing mechanism 23 is a linear reciprocating electric push rod. The mechanism 23 pushes the movable tube 27 to move. The retraction of the movable tube 27 avoids obstruction when the rotating disk 7 moves up and down. One end of the pushing mechanism 23 is fixed with a movable disk 26. The movable tube 27 is welded to the movable disk 26. The movable tube 27 has a blow hole 28. The blow hole 28 is movably installed at the bottom of the filter seat 10. A sealing ring is installed between the movable tube 27 and the fixed tube 24. The support mechanism 33 is a support spring. When the feed hopper 6 loses support, the support spring pushes the feed hopper 6 to move downward and return to its original position.

[0043] In use, the device involves manually picking up particles from the conveyor belt using a container, then pouring them into the feed hopper 6. Before pouring, a quantitative amount is dispensed from the feed hopper 6. During this quantitative dispensing, the displacement mechanism 19 is activated, driving the drive motor 21 upwards. The rotating column 8 on the drive motor 21 pushes the conical seat 9 into the feed hopper 6. The height of the conical seat 9 within the feed hopper 6 is adjusted, and moving it to different heights allows for quantitative feeding into the feed hopper 6. Once the conical seat 9 enters the feed hopper 6, it creates a blocking point, preventing the particles from entering the hopper. After the granular fertilizer is poured into the feed hopper 6, the conical seat 9 provides support. Once the fertilizer reaches the top of the feed hopper 6, the feeding stops, and the rotating column 8 moves downwards. Simultaneously, the rotating disk 7 and the ring seat 11 return to their original positions. The lifting mechanism 5 pushes the ring seat 11 downwards along with the rotating disk 7. As the rotating disk 7 and rotating column 8 descend, the conical seat 9 is removed from the feed hopper 6. After the conical seat 9 is removed, the granules are no longer obstructed and fall onto the rotating disk 7. The drive motor 21 is then started, causing the rotating column 8 and rotating disk 7 to rotate. When rotating, the fixed rod 12 remains stationary, and the particles collide with the fixed rod 12 and tumble. The tumbled particles are more easily filtered through the filter seat 10. When the rotating disk 7 rotates, the pushing mechanism 23 is activated to move the movable tube 27. The air blowing hole 28 on the movable tube 27 moves to the bottom of the filter seat 10. When the filter seat 10 passes the air blowing hole 28, the airflow from the air blowing hole 28 causes the particles on the filter seat 10 to move upward, thereby avoiding clogging of the filter seat 10. The particles filtered through the filter seat 10 fall between the partition plates 15 for further processing. The filter seat 10 is used to screen particles of a certain size, which facilitates the standardization of subsequent testing. After the separator plate 15 is full, the rotating column 8 moves downward, and the friction seat 13 contacts the top of the support seat 14. The friction seat 13 drives the support seat 14 to rotate 90 degrees, changing the position of the separator plate 15, which facilitates collection again. At the same time as collection, the separator plate 15 moves to the discharge port position, and the movable plate 2 moves upward to discharge the particles outward through the inclined angle of the support seat 14. When collecting in another position, it does not delay the discharge of the other position.
