Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sand mill technology, and in particular relates to a sand mill for pesticide suspension. Background Technology
[0002] Pesticide suspensions are viscous, flowable suspensions made by mixing pesticide active ingredients, carriers, and dispersants, and then ultra-finely pulverizing them using a wet process. They consist of solid active ingredients that are insoluble or slightly soluble in water, dispersed relatively uniformly in water with the help of certain adjuvants through ultra-fine pulverization, forming a stable, flowable liquid-solid system with fine particles. The production of pesticide suspensions is mostly accomplished using sand mills.
[0003] The existing sand mills do not mix evenly enough during use, which means that the fixed active ingredients that are insoluble or slightly soluble in water cannot be well dispersed in the water, reducing the working efficiency of the sand mill. Secondly, when the pesticide suspension is discharged, it needs to be filtered. If the filter screen is not disassembled for cleaning, the cleaning impurities will still fall directly into the discharge box and may be discharged together with the pesticide suspension. Utility Model Content

[0005] This utility model is implemented as follows: a pesticide suspension sand mill includes an installation plate, with side plates symmetrically connected to the top of the installation plate. A rotatable sand mill cylinder is provided inside the side plates. A feed pipe is provided at the top of the sand mill cylinder, and a driveable stirring shaft is provided inside the sand mill cylinder. A discharge pipe is provided at the bottom of the sand mill cylinder. An installation groove is opened in the middle of the installation plate, and a filter screen is provided inside the installation groove. A cleaning component is provided below the filter screen. A fixed box is installed below the installation groove. A baffle is fixedly connected to the upper part of the fixed box. A discharge port is opened in the middle of the baffle, and a rotatable discharge pipe is connected below the discharge port.

[0008] Preferably, the cleaning component includes a third motor, which is installed inside a groove on one side of the mounting slot. The output end of the third motor is connected to a bidirectional screw. The two ends of the bidirectional screw are symmetrically connected to threaded blocks. A cleaning brush is fixedly connected to the top of the threaded block, and the top of the cleaning brush is in contact with the filter screen.
[0009] Preferably, a guide plate is symmetrically connected inside the mounting groove below the bidirectional screw, the bottom of the guide plate is located above the discharge port, a load-bearing plate is fixedly connected to the upper side of one side of the inner wall of the fixed box, a fourth motor is installed on the top of the load-bearing plate, a first gear is connected to the output end of the fourth motor, a second gear is connected to the outside of the discharge pipe, the first gear and the second gear mesh, a guide pipe is connected to the bottom wall of the fixed box diagonally below the second gear, and a residue collection box is provided on the bottom wall of the fixed box diagonally below the first gear.
[0010] Compared with the prior art, the embodiments of this application have the following main advantages:
[0011] Through the coordinated arrangement of the first motor, stirring shaft, stirring rod, grinding drum, second motor, driving wheel, and driven wheel, the solid active ingredient, carrier, and dispersant can be stirred, resulting in a more uniform mixture. This prevents the active ingredient from failing to bind well with the dispersant and thus dispersing in the water, thereby improving the production efficiency of pesticide suspensions. Secondly, through the coordinated arrangement of the baffle, discharge port, discharge pipe, fourth motor, first gear, second gear, guide pipe, and residue collection box, the discharge end of the discharge pipe is positioned above the guide pipe during normal filtration and residue discharge.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0019] This utility model embodiment provides a pesticide suspension concentrate sand mill, such as Figure 1-4 As shown, the assembly includes a mounting plate 1, with side plates 2 symmetrically connected to the top of the mounting plate 1. A rotatable grinding cylinder 3 is provided inside the side plates 2. A feed pipe 301 is provided at the top of the grinding cylinder 3. A driveable stirring shaft 4 is provided inside the grinding cylinder 3. A discharge pipe 302 is provided at the bottom of the grinding cylinder 3. A mounting groove 101 is provided in the middle of the mounting plate 1. A filter screen 5 is provided inside the mounting groove 101. A cleaning component is provided below the filter screen 5. A fixed box 6 is installed below the mounting groove 101. A baffle 7 is fixedly connected to the upper part of the fixed box 6. A discharge port is provided in the middle of the baffle 7. A rotatable discharge pipe 8 is connected below the discharge port.
[0020] It should be noted that existing sand mills do not mix evenly enough during use, resulting in insoluble or slightly soluble fixed active ingredients not dispersing well in water, thus reducing the efficiency of the sand mill. Secondly, when pesticide suspensions are discharged, filtration is required. If the filter screen is not disassembled for cleaning, impurities will still fall directly into the discharge box and may be discharged along with the pesticide suspension. This solution addresses this issue by using a coordinated arrangement of the first motor 9, stirring shaft 4, stirring rod 401, sand mill cylinder 3, second motor 10, driving wheel 11, and driven wheel 12 to mix solid active ingredients, carriers, and dispersants. This allows for more uniform mixing, preventing the active ingredient from failing to bind well with the dispersant and thus dispersing in the water, thereby improving the production efficiency of pesticide suspensions. Secondly, through the coordinated arrangement of baffle 7, discharge port, discharge pipe 8, fourth motor 19, first gear 20, second gear 21, guide pipe 22, and residue collection box 23, the discharge end of discharge pipe 8 is positioned above guide pipe 22 during normal filtration and residue discharge. When cleaning residue from filter screen 5, discharge pipe 8 can be rotated to the top of residue collection box 23 to prevent residue from being discharged along with guide pipe 22, thus improving the production quality of pesticide suspensions.
[0021] Specifically, in this embodiment, the solution mainly includes a mounting plate 1, a mounting plate 1, a side plate 2 symmetrically connected to the top of the mounting plate 1, a rotatable grinding cylinder 3 provided inside the side plate 2, a feed pipe 301 provided at the top of the grinding cylinder 3, a driveable stirring shaft 4 provided inside the grinding cylinder 3, a discharge pipe 302 provided at the bottom of the grinding cylinder 3, a mounting groove 101 opened in the middle of the mounting plate 1, a filter screen 5 provided inside the mounting groove 101, a cleaning component provided below the filter screen 5, a fixed box 6 installed below the mounting groove 101, a baffle 7 fixedly connected to the upper part inside the fixed box 6, a discharge port opened in the middle of the baffle 7, and a rotatable discharge pipe 8 connected below the discharge port.
[0022] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, a first motor 9 is fixedly installed on the side wall of a side plate 2. One end of the stirring shaft 4 passes through the sand mill cylinder 3 and the other end is connected to the output end of the first motor 9. Multiple stirring rods 401 are evenly distributed on the side wall of the stirring shaft 4. A second motor 10 is fixedly installed on the inner side wall of another side plate 2. The output end of the second motor 10 is connected to a drive wheel 11. Another drive wheel 11 is provided on the opposite side of the sand mill cylinder 3 away from the output end of the second motor 10 drive wheel 11. Driven wheels 12 are symmetrically provided at both ends of the outer side of the sand mill cylinder 3. The two driven wheels 12 are evenly meshed with the two corresponding drive wheels 11.
[0023] In this embodiment, when the power is turned on, the first motor 9 drives the stirring shaft 4 to rotate, and the stirring shaft 4 drives multiple stirring rods 401 to rotate. This allows the fixed raw material, carrier, and mixture to be stirred inside the sand mill 3, thereby mixing them evenly and accelerating the dispersion of the fixed raw material in water. When the power is turned on, the second motor 10 drives the drive wheel 11 to rotate. The meshing between the two drive wheels 11 and the driven wheel 12 causes them to rotate, allowing the sand mill 3 to rotate, further improving the efficiency of dispersing the solid raw material in water.
[0024] In a further preferred embodiment of the present invention, Figure 2 As shown, both the feed pipe 301 and the discharge pipe 302 are equipped with sealing plugs 13.
[0025] In this embodiment, when the grinding cylinder 3 rotates, the inner side of the feed pipe 301 and the discharge pipe 302 can be sealed by the sealing plug 13 to prevent liquid from flowing out.
[0026] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the cleaning assembly includes a third motor 14, which is installed inside a groove on one side of the mounting slot 101. The output end of the third motor 14 is connected to a bidirectional screw 15. The two ends of the bidirectional screw 15 are symmetrically connected to threaded blocks 16. A cleaning brush 17 is fixedly connected to the top of the threaded block 16. The top of the cleaning brush 17 is in contact with the filter screen 5.
[0027] In this embodiment, when the power is turned on, the third motor 14 drives the bidirectional screw 15 to rotate. The bidirectional screw 15 drives the two threaded blocks 16 connected to it to move relative to each other. The two threaded blocks 16 drive the two cleaning brushes 17 to move, thereby cleaning the residue on the filter screen 5 and preventing the filter screen 5 from becoming clogged and unable to filter impurities in the pesticide suspension.
[0028] In a further preferred embodiment of the present invention, Figure 3 As shown, a guide plate 18 is symmetrically connected inside the mounting groove 101 below the bidirectional screw 15. The bottom of the guide plate 18 is located above the discharge port. A load-bearing plate is fixedly connected to the upper side of one side of the inner wall of the fixed box 6. A fourth motor 19 is installed on the top of the load-bearing plate. The output end of the fourth motor 19 is connected to a first gear 20. A second gear 21 is connected to the outside of the discharge pipe 8. The first gear 20 and the second gear 21 mesh. A guide pipe 22 is connected to the bottom wall of the fixed box 6 at an angle below the second gear 21. A residue collection box 23 is provided on the bottom wall of the fixed box 6 at an angle below the first gear 20.
[0029] In this embodiment, the filtered pesticide suspension enters the discharge pipe 8 through the guide plate 18 and the discharge port, and is finally discharged through the guide pipe 22. When cleaning the filter screen 5 for residue, the power can be turned on first, the fourth motor 19 drives the first gear 20 to rotate, the first gear 20 drives the second gear 21 meshing with it to rotate, and the second gear 21 drives the discharge pipe 8 to rotate above the residue collection box 23 on the other side, so that the filter screen 5 can be cleaned for residue, so that the residue is separated from the pesticide suspension, which can effectively improve the production quality of the pesticide suspension.
