Description

Technical Field

[0001] The invention relates to the technical field of particle inspection, in particular to a grinder for fertilizer particle inspection. Background Art

[0002] As a base fertilizer for crops, compound fertilizer (compound fertilizer) has the advantages of uniform nitrogen, phosphorus and potassium content and stable physical properties. Unlike topdressing fertilizer, it has a slow dissolution speed and a long fertilizer effect. In order to ensure the growth and yield of crops, content testing is an indispensable link for both processing companies and supervisory departments. Based on the characteristics of compound fertilizer, unlike instant fertilizers such as urea, it needs to be ground, dissolved in a solvent, and tested.

[0003] In the prior art, when a compound fertilizer is ground by a grinder, a compound fertilizer sample is placed in a grinding component, and the grinding component is driven by a driving component to rotate to grind the compound fertilizer. At the same time, in order to ensure the fineness of the grinding, the grinding space will gradually change from large to small, thereby performing multi-stage grinding on the compound fertilizer to ensure the fineness of the grinding.

[0004] Since compound fertilizer has the characteristic of absorbing moisture, compound fertilizer powder is likely to remain on the surface of the grinding parts after grinding. In order to eliminate the impact of the residue on the inspection and detection of other batches of samples, the grinding parts need to be disassembled for cleaning. The disassembly and assembly of the grinding parts of most grinders requires the disassembly of their fixed parts. The disassembly and assembly process is cumbersome, resulting in low inspection and detection efficiency. Summary of the invention

[0005] The invention provides a grinder for inspecting fertilizer particles, which is convenient for removing a grinding component of the grinder to clean up residual compound fertilizer powder, thereby preventing different types of compound fertilizers from mixing during grinding, and the grinding component of the grinder can be disassembled and assembled more quickly and conveniently.

The grinding parts of the grinder are quicker and more convenient to disassemble and assemble, making the grinder more suitable for the inspection of different types of compound fertilizers. The flow of air is used to apply a downward force to the sample, thereby increasing the friction between the sample and the grinding parts and accelerating the grinding efficiency of the sample.

A connecting pipe is provided between the discharge port of the upper hopper and the feed port of the conical hopper to facilitate the loading of the compound fertilizer.

[0009] Furthermore, the collecting mechanism includes an inner ring, an outer ring and a filter plate. The inner ring is movably sleeved on the outer arc surface of the circular tube in the middle of the partition. The outer arc surface of the outer ring fits with the inner arc surface of the grinding shell.

[0012] Furthermore, a rotating ring is provided at the upper end of the support tube, and the rotating ring is movably sleeved on the outer arc surface of the grinding shell.

[0013] Furthermore, a rubber sealing pad is provided at the lower end of the outer arc surface of the support tube, and the rubber sealing pad is fitted with the inner arc surface of the grinding shell.

[0014] Furthermore, balls are rotatably connected in the rotating grooves on the upper surface of the partition, and the balls are in contact with the lower surface of the conical grinding column.

[0021] A grinding shell 2 is provided on the upper surface of the bottom shell 1 to provide space for the arrangement of the grinding components. The upper end of the grinding shell 2 is an open structure to provide space for the disassembly and assembly of the grinding components. A partition 3 is provided at the lower end of the inner arc surface of the grinding shell 2 to separate the interior of the grinding shell 2. A rotating column 4 is rotatably connected to the middle part of the partition 3 through a bearing. A plug-in column 5 is inserted into a slot on the upper surface of the rotating column 4. A conical grinding column 6 is provided on the upper end of the plug-in column 5. The plug-in column 5 is inserted into the slot on the upper surface of the rotating column 4 to limit the relative rotation of the plug-in column 5 and the rotating column 4. Under the connection of the plug-in column 5, when the rotating column 4 rotates, the conical grinding column 6 also rotates accordingly. A control switch 10 is provided at the front end of the bottom shell 1 to control the start and stop of the overall device. A driving motor 11 is provided at the rear end of the upper surface of the bottom shell 1, and a pulley 12 is provided at the lower end of the output shaft of the driving motor 11 and the lower end of the rotating column 4.

The driving motor 11 is started, and the output shaft of the driving motor 11 drives the pulley 12 on the rear side to rotate. Through the transmission connection of the belt 13, the pulley 12 on the front side drives the rotating column 4 to rotate. Balls 16 are rotatably connected in the rotating grooves on the upper surface of the partition 3, and the balls 16 are all in contact with the lower surface of the conical grinding column 6. The relative rolling of the balls 16 and the conical grinding column 6 reduces the friction force on the conical grinding column 6 during rotation.

[0022] The disassembly and assembly mechanism 8 is arranged at the upper end of the grinding shell 2, and a conical grinding ring 7 is arranged at the lower end of the disassembly and assembly mechanism 8. The distance between the inner arc surface of the conical grinding ring 7 and the outer arc surface of the conical grinding column 6 gradually decreases from top to bottom. When the sample is located between the inner arc surface of the conical grinding ring 7 and the outer arc surface of the conical grinding column 6, the conical grinding column 6 is driven to rotate, and the sample is ground through the cooperation of the conical grinding column 6 and the conical grinding ring 7. The further the sample moves downward, the higher the grinding effect of the sample is. The disassembly and assembly mechanism 8 includes a support tube 81 and a conical bucket 84. The support tube 81 is threadedly connected to the upper end of the grinding shell 2, and a conical bucket 84 is arranged at the lower end of the support tube 81. The inner arc surface of the conical bucket 84 is provided with a conical grinding ring 7 to provide support for the setting of the conical grinding ring 7. The disassembly and assembly mechanism 8 also includes an upper hopper 82 and a connecting tube 83.

Under the guidance of the upper hopper 82, the sample enters the conical hopper 84 from the connecting pipe 83, which is convenient for loading. After the grinding is completed, the support tube 81 is rotated, and the support tube 81 is threadedly connected to the grinding shell 2 to pull the support tube 81 out of the grinding shell 2, and then the plug column 5 is pulled out from the slot on the upper surface of the rotating column 4, so as to facilitate the cleaning of the parts in contact with the sample during the grinding process, avoid mixing of different types of compound fertilizers during grinding, and ensure the accuracy of the compound fertilizer inspection results. The upper end of the support tube 81 is provided with a swivel 14, and the swivel 14 is movably sleeved on the outer arc surface of the grinding shell 2 to facilitate the rotation of the support tube 81. The lower end of the outer arc surface of the support tube 81 is provided with a rubber sealing pad 15, and the rubber sealing pad 15 is fitted with the inner arc surface of the grinding shell 2 to seal the grinding shell 2 and the support tube 81.

[0023] The collecting mechanism 9 is arranged on the outer side surface of the bottom shell 1 and the lower end of the grinding shell 2. The collecting mechanism 9 includes an inner ring 91, an outer ring 92 and a filter plate 93. The inner ring 91 is movably sleeved on the outer arc surface of the circular tube in the middle of the partition 3. The outer arc surface of the outer ring 92 fits the inner arc surface of the grinding shell 2. A filter plate 93 is arranged between the inner arc surface of the outer ring 92 and the outer arc surface of the inner ring 91. The sample after grinding will fall onto the surface of the filter plate 93. The collecting mechanism 9 also includes air holes 94, fan blades 95 and air outlet holes 96. The fan blades 95 are arranged on the outer arc surface of the rotating column 4. The fan blades 95 are located on the lower side of the partition 3. The air holes 94 are respectively arranged on the bottom wall of the partition 3, the upper surface of the bottom shell 1 and the bottom wall of the grinding shell 2. The air outlet holes 96 Holes 96 are provided on the left and right sides of the bottom shell 1. During the grinding process, the fan blades 95 rotate with the rotating column 4, driving the air to flow, so that the air flows along the upper hopper 82, the connecting pipe 83, between the inner arc surface of the conical grinding ring 7 and the outer arc surface of the conical grinding column 6, between the inner ring 91 and the outer ring 92, the air holes 94, the inside of the bottom shell 1 and the air outlet holes 96, exerting a downward force on the sample to accelerate the grinding efficiency of the sample. At the same time, the airflow drives the ground sample to fall to the surface of the filter plate 93, and the filter plate 93 is used to filter the air and the ground sample, so that the ground sample is more thoroughly concentrated on the surface of the filter plate 93, reducing the residue of compound fertilizer on the surface of the grinding component.

[0024] The present invention provides a fertilizer particle inspection grinder, and its working principle is as follows: During the inspection of compound fertilizer, when it is necessary to grind the inspected compound fertilizer, the sample is poured into the upper hopper 82. Under the guidance of the upper hopper 82, the sample is allowed to enter the conical hopper 84 from the connecting pipe 83. At this time, the sample is located between the inner arc surface of the conical grinding ring 7 and the outer arc surface of the conical grinding column 6. The driving motor 11 is started by controlling the switch 10. The output shaft of the driving motor 11 drives the pulley 12 on the rear side to rotate. The front pulley 12 drives the rotating column 4 to rotate through the transmission connection of the belt 13. At the same time, the plug post 5 is plugged into the slot on the upper surface of the rotating column 4 to limit the relative rotation of the plug post 5 and the rotating column 4. Under the connection of the plug post 5, the conical grinding column 6 is rotated. Through the cooperation of the conical grinding column 6 and the conical grinding ring 7, the sample is ground. During the grinding process, the fan blades 95 rotate with the rotating column 4 to drive the air to flow, so that the air moves along the upper hopper 82, the connecting pipe 83, the inner arc surface of the conical grinding ring 7 and the outer arc surface of the conical grinding column 6. The air flows between the inner ring 91 and the outer ring 92, through the air holes 94, inside the bottom shell 1 and the air outlet holes 96. Under the action of the airflow, a downward force is applied to the sample, thereby increasing the friction between the sample and the grinding components and accelerating the grinding efficiency of the sample. At the same time, the airflow drives the ground sample to fall onto the surface of the filter plate 93, and the filter plate 93 is used to filter the air and the ground sample, so that the ground sample is more thoroughly concentrated on the surface of the filter plate 93. After the grinding is completed, the support tube 81 is rotated, and the support tube 81 is threadedly connected to the grinding shell 2 to pull the support tube 81 out of the grinding shell 2, and then the plug 5 is pulled out of the slot on the upper surface of the rotating column 4, and finally the inner ring 91, the outer ring 92 and the filter plate 93 are pulled out as a whole, so that the ground sample is taken out. At the same time, it is convenient to clean the parts that come into contact with the sample during the grinding process, avoid mixing of different types of compound fertilizers during grinding, and ensure the accuracy of the compound fertilizer inspection results.
