Description

Technical Field

[0001] The utility model relates to the field of compound fertilizer mixing, and specifically relates to a compound fertilizer mixer. Background Art

[0002] A compound fertilizer mixer is a device used to evenly mix fertilizers with different components. It is usually used in agriculture and horticulture to ensure the effectiveness and uniformity of fertilizers. Generally, it stirs materials in the horizontal or vertical direction using spiral blades, suitable for mixing multiple components, with flexible operation and easy adjustment of the mixing ratio, for medium and small-sized fertilizer mixing and processing. Considering the simplicity of equipment operation and maintenance requirements to reduce production costs and downtime, the compound fertilizer mixer can ensure the uniform mixing of fertilizer components and improve the effect and utilization efficiency of fertilizers.

[0003] In the specific mixing of compound fertilizers, the usual compound fertilizer mixers cannot grasp the ratio of compound fertilizers, and all fertilizers use the same feed pipe. After long-term use, the feed pipe is seriously polluted. Moreover, when the compound fertilizer is mixed for a long time, the inner wall of the mixing barrel is likely to be stained with residues, resulting in a reduced service life of the compound fertilizer mixer and inconvenience for the operator to use.

After the measurement is completed, by controlling the valves on the surfaces of the two groups of feed hoppers 14, the compound fertilizer can be put into the inside of the stirring barrel 12. After completion, the operator can start the servo motor 13 to drive the fixed shaft 16 to rotate, and the fixed shaft 16 drives the stirring rods 17 to rotate and stir. After the stirring is completed, by controlling the valve on the discharge pipe 27, the mixed compound fertilizer can be taken out.

[0022] Refer to Figures 1 to 4, in a preferred embodiment, a water inlet pipe 19 and a measuring scale 15 are provided at the top of the stirring barrel 12. A cleaning brush 18 is provided at one end of the stirring rod 17. A limiting bar 24 is provided on one side of the fixing frame 11. The limiting bar 24 is arranged on the surface of the stirring barrel 12. A limiting rod 28 is provided on one side of the limiting bar 24. By providing the limiting rod 28 and the limiting bar 24, the position of the stirring barrel 12 can be limited. An observation window 23 is provided on the surface of the stirring barrel 12. By providing the observation window 23, it is convenient for the operator to observe the internal situation of the stirring barrel 12. An installation rod 29 is provided on one side of the fixing frame 11. A bearing sleeve 26 is provided at the top of the installation frame 2. One end of the installation rod 29 is connected to the bearing sleeve 26. A PLC controller 22 is provided at the top of the reduction motor 21. By providing the PLC controller 22, the servo motor 13 and the reduction motor 21 can be controlled. Through the mutual cooperation of the stirring barrel 12, the water inlet pipe 19, the servo motor 13, the fixed shaft 16, the stirring rod 17, the cleaning brush 18 and the reduction motor 21, when the operator needs to improve the stirring effect of the compound fertilizer, the operator can start the reduction motor 21 to drive the fixing frame 11 to rotate, and the fixing frame 11 can drive the stirring barrel 12 to rotate, so as to improve the mixing effect of the compound fertilizer and make it more convenient to take out. When the compound fertilizer is mixed for a long time and the inner wall of the stirring barrel 12 is stained with residues, the operator can pour water into the stirring barrel 12 through the water inlet pipe 19 by an external water source. After completion, the operator can start the servo motor 13 to drive the fixed shaft 16 to rotate, and the fixed shaft 16 can drive the stirring rod 17 and the cleaning brush 18 to rotate, so as to clean the residues in the inner cavity of the stirring barrel 12.

By providing the installation covers, when the stirring barrel 12 rotates, the compound fertilizer inside the stirring barrel 12 can be prevented from being thrown out. The stirring barrel 12 is arranged in an inclined shape. By arranging the stirring barrel 12 in an inclined shape, the discharge efficiency of the compound fertilizer can be improved.

[0024] Specifically, the working process or working principle of the compound fertilizer mixer is as follows: in the specific mixing of compound fertilizers, the conventional compound fertilizer mixer cannot grasp the ratio of compound fertilizers, and all fertilizers use the same feed pipe. In this way, the feed pipe is seriously polluted after long-term use, and after the compound fertilizers are mixed for a long time, the inner wall of the mixing barrel 12 is easily stained with residues, thereby reducing the service life of the compound fertilizer mixer and being inconvenient for the operator to use. Therefore, the technical solution can solve the above problems. When the operator mixes the compound fertilizers, the operator first needs to put different fertilizers into the mixing barrel 12 through different feed hoppers 14. When putting them in, the height can be measured by the measuring ruler 15 to proportion the mixed amount of the fertilizers. After the measurement is completed, the valves on the surfaces of the two groups of feed hoppers 14 can be controlled to put the compound fertilizer into the mixing barrel 12. After completion, the operator can start the servo motor 13 to drive the fixed shaft 16 to rotate, and the fixed shaft 16 drives the stirring rod 17 to rotate and stir. After the mixing is completed, the valve on the discharge pipe 27 is controlled to take out the mixed compound fertilizer. When the operator needs to improve the mixing effect of the compound fertilizer, the operator can start the reduction motor 21 to drive the fixed frame 11 to rotate, and the fixed frame 11 can drive the mixing barrel 12 to rotate, so as to improve the mixing effect of the compound fertilizer and make it more convenient to take out. When the operator mixes the compound fertilizer for a long time, the inner wall of the mixing barrel 12 is stained with residue, the operator can use an external water source to pour water into the mixing barrel 12 through the water inlet pipe 19. When it is completed, the operator can start the servo motor 13 to drive the fixed shaft 16 to rotate, and the fixed shaft 16 can drive the stirring rod 17 and the cleaning brush 18 to rotate, so as to clean the residue in the inner cavity of the mixing barrel 12, and by starting the reduction motor 21 to drive the mixing barrel 12 to rotate, the cleaning effect can be further improved, so as to extend the service life of the compound fertilizer mixer and facilitate the operator to use it. At this point, all processes are completed.
