Description

Technical Field

[0001] The utility model relates to the technical field of pesticide production, and particularly relates to a granulating mechanism for pesticide production. Background Art

[0002] In agricultural production, the use of pesticides is inevitable. There are a very rich variety of pesticides, including powder pesticides, aqueous pesticides, and granular pesticides. Granulating equipment is required for the production of granular pesticides.

[0003] After inspection, Chinese Patent Publication No. CN220386474U discloses a granulating mechanism for pesticide production, which includes a granulating box. A driving motor is installed above the granulating box. The output end of the driving motor is connected to a lead screw. A pressing plate is threadedly connected to the lead screw. Convex blocks are arranged inside the granulating box, and grooves adapted to the convex blocks are arranged outside the pressing plate. The advantages of the utility model are as follows: By setting the granulating box, driving motor, lead screw, pressing plate, convex blocks and grooves, when in use, the motor works to drive the pressing plate to descend, thereby pressing the raw materials inside the granulating box, so that the raw materials are discharged from the leakage holes of the carrier plate and are cut into granules under the action of the rotating scraper. The manufactured granules fall onto the metal mesh funnel, and the granules falling on the metal mesh funnel are quickly dried under the action of the hot air blown by the heating pipe and the hot air blower. They can also be continuously dried during the process of falling through the spiral pipeline. Double drying improves the granulation efficiency.

[0004] However, in the above technical solution, only the heating pipe and the hot air blower are used to dry the pesticide granules. The time and distance of the pesticide granules falling are fixed. When facing different types and viscosities of pesticide granules, the drying effect is different. When the humidity changes during the manufacture of the same pesticide granules, it is also easy to cause insufficient drying effect, resulting in adhesion of the pesticide granules.

[0014] In the present utility model, when the heating assembly is in use, it will heat the air in the granulation box to accelerate the drying of the pesticide raw materials, avoiding the excessive humidity and viscosity of the pesticide from sticking to each other.

[0024] Embodiment Three

[0025] As Figures 2 - 3 shown in the figure, a granulation mechanism for pesticide production proposed by the present utility model. Compared with the second embodiment, the detailed structures of the heating assembly, the feeding assembly, and the screening assembly are described in this embodiment. The heating assembly includes a hot air blower 7 and an air outlet pipe 8. Two hot air blowers 7 are symmetrically arranged and connected to the outer wall of the granulation box 1. The air outlet ends of the hot air blowers 7 are both connected to the air outlet pipe 8, and one end of the air outlet pipe 8 extends into the granulation box 1; the air outlet pipe 8 is in an L shape and is closely attached to the feeding assembly, and a plurality of air outlet holes are provided on the air outlet pipe 8.

[0026] The feeding assembly includes a support mesh plate 9, a fixed cylinder 10, a motor 11, an output shaft 12, and a spiral blade 13. The fixed cylinder 10 is connected to the center position of the bottom of the granulation box 1. One end of the fixed cylinder 10 extends out of the granulation box 1 and is closed, and the other end of the fixed cylinder 10 is connected to the support mesh plate 9; the support mesh plate 9 is in a funnel shape and is connected to the inner wall of the granulation box 1; the motor 11 is connected to the end of the fixed cylinder 10 away from the support mesh plate 9, the output end of the motor 11 is connected to the output shaft 12 arranged in the fixed cylinder 10, and the outer peripheral surface of the output shaft 12 is used to connect the spiral blade 13; the spiral blade 13 is attached to the inner wall of the fixed cylinder 10, and a friction layer is connected to each spiral blade 13. The friction layer is made of rubber or other materials with high surface roughness.

[0027] In an optional embodiment, a baffle 22 is connected to the inner wall of the granulation box 1, and an opening is provided on the granulation box 1 above the baffle 22; wherein, the baffle 22 is inclined, and the lower end with a lower angle of the baffle 22 is used to open the opening. The baffle 22 collects the pesticide residues falling in the support mesh plate 9 and centrally collects them from the opening at one end to reduce waste, and avoids the physical harm caused to the staff by manually collecting pesticides.

[0028] The screening component includes a sliding rod 14, a fixed seat 15, a filter mesh plate 16, an elastic member 17, and a power component. Both ends of the sliding rod 14 are used to connect to the fixed seat 15. The fixed seat 15 is connected to the inner wall of the fixed cylinder 10. The sliding rod 14 and the fixed seat 15 are circumferentially distributed around the central axis of the fixed cylinder 10. The filter mesh plate 16 is slidably connected to the sliding rod 14. Elastic members 17 are provided on both the upper and lower sides of the filter mesh plate 16 and are sleeved outside the sliding rod 14. The elastic member 17 is selected as a spring. The elastic member 17 causes the filter mesh plate 16 to gradually return to the initial position after completing the up and down movement. At the same time, after a large vibration occurs, the elastic member 17 will cause it to vibrate slightly multiple times subsequently, enhancing the vibration effect.

[0029] The power component includes a fixed ring 18, a ratchet rack 19, a mounting rod 20, and a moving wheel 21. The fixed ring 18 is connected to the upper end face of the filter mesh plate 16.

The mounting rod 20 is connected to the outer peripheral surface of the top of the output shaft 12. One end of the mounting rod 20 is used to connect to the moving wheel 21. The shape of the mounting rod 20 is L-shaped.

[0030] In summary, when the present utility model is in use, the hot air blower 7 is started to heat the air and discharge it into the granulation box 1 through the air outlet pipe 8 to increase the temperature of the granulation box 1. The staff adds the pesticide raw materials into the granulation cylinder 3 from the feed port 2. After starting the driving device 5, the driving device 5 drives the spiral auger 6 to rotate and gradually move the raw materials closer to the support plate 4. It is extruded and formed through the granulation holes on the support plate 4. The cutting blade below the support plate 4 cuts it into particles. The cut pesticide particles fall on the support mesh plate 9, and the debris will slide out of the granulation box 1 from the air into the lower baffle 22. The normal pesticide particles will be guided by the support mesh plate 9 into the fixed cylinder 10. At this time, the motor 11 is started to make it rotate, which can drive the output shaft 12 and the spiral blade 13 to rotate. The spiral blade 13 rotates in the reverse direction to slow down the falling speed of the particles and increase the time they stay in the granulation box 1, thereby improving the drying effect and preventing the pesticide particles from sticking to each other. At the same time, the rotation of the output shaft 12 will drive the moving wheel 21 to rotate synchronously through the mounting rod 20. During the rotation of the moving wheel 21, it contacts the ratchet rack 19 connected to the fixed ring 18. The slope driven by the ratchet teeth will drive the fixed ring 18 and the filter mesh plate 16 to move when it contacts the moving wheel 21. The filter mesh plate 16 moves up and down along the axis of the sliding rod 14 to generate vibration, screening out the pesticide particles falling on the filter mesh plate 16 to make them fall normally and separating the mutually adhered pesticide particles.

[0031] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art to which it pertains.
