Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a grinding device for fertilizer production. Background Art

[0002] Fertilizer refers to a substance added to the soil to provide the nutrients needed for plant growth. They can be organic (such as animal manure, plant residues, etc.) or inorganic (such as chemical compounds such as nitrogen, phosphorus, potassium, etc.). The main function of fertilizers is to provide nutrients for plants, promote plant growth and development, increase yields and improve crop quality. During the fertilizer production process, the fertilizer needs to be ground. After grinding, the fertilizer particles are more uniform in size and can be better mixed with the soil, making the nutrient distribution more even, which is conducive to plant root absorption.

By setting an inspection door, it is convenient for workers to inspect and maintain the equipment. By setting the grinding device, primary crushing of pig feed is achieved. The surface of the grinding sheet is a rough surface, which can enhance the crushing effect of the device and make the grinding more fine and sufficient. A filter net is provided at the bottom of the screening frame to filter unqualified agglomerated pig feed, thereby improving production efficiency. The crushing device is provided with a crushing blade that can perform secondary crushing of pig feed to improve the crushing effect.

Here, the displacement of the fixed shaft 13 is designed to make the rotating frame 14 rotate, and the outer top side of the rotating frame 14 is fixedly connected with a fixed sleeve 15. The fixed sleeve 15 is externally rotatably connected to a rotating frame 16, and the rotating frame 16 is externally slidably connected to a limiting frame 17. The design here is to limit the rotating frame 16 with the help of the limiting frame 17.

The left and right sides of the inside of the outer shell 1 are provided with a plurality of sliding grooves 22. The far sides of the two screening plates 9 are fixedly connected with an inclined plate 26. The design here uses the inclined plate 26 to allow the fertilizer to fall into the inside of the collecting box 23.

[0028] Reference Figure 2 - Figure 4, multiple elastic components all include fixed columns 19, and the adjacent sides of the multiple fixed columns 19 are respectively fixedly connected to the outside of the two screening plates 9, and the outsides of the multiple fixed columns 19 are all sleeved with springs 20.

[0030] Working principle: when it is necessary to grind the fertilizer, it is only necessary to pour the fertilizer raw material into the interior of the housing 1 through the feed rack 25, and at the same time, it is necessary to start the motor 3, and the driving gear 4 is driven to rotate by the rotation of the output end of the motor 3. At this time, the driven gear 5 can also rotate by virtue of the meshing connection between the driving gear 4 and the driven gear 5, and at this time, the active grinding roller 6 and the driven grinding roller 7 are driven to rotate. At this time, the fertilizer dropped through the feed rack 25 will be ground by the active grinding roller 6 and the driven grinding roller 7, and under the action of gravity, the ground fertilizer will fall to the top of the screening plate 9;

At this time, as the rotating disk 12 rotates, the fixed shaft 13 will make a circular motion, and the rotating frame 14 will rotate outside the fixed shaft 13. Then, as the rotating frame 14 is displaced, the fixed sleeve 15 will be displaced, and then the rotating frame 2 16 can be displaced. At this time, the displacement of the rotating frame 2 16 can be limited by the limit frame 17. At this time, the rotating frame 2 16 can repeatedly hit the fixed plate 18, and then the screening plate 9 can be displaced. As the screening plate 9 is displaced, the fertilizer that does not meet the standards will fall into the inside of the collecting box 23 under the action of gravity, and the fertilizer that meets the standards will fall into the inside of the collecting frame 24 under the action of the screening plate 9. At this time, the collecting box 23 can be pulled out with the help of the handle, and the fertilizer that has not been thoroughly ground inside can be poured back into the inside of the feeding frame 25, and the ground fertilizer will be collected through the collecting frame 24.
