During the production process, pesticides require particle sorting. Sorting removes unqualified large and small particles, making the pesticide particles more uniform in size. This ensures that the pesticide can be more evenly dispersed and cover the target area during application, thereby improving its efficacy.

[0020] Example 1

[0021] like Figures 1-4 As shown, the pesticide particle sorting device proposed in this embodiment includes a base 1 and a dispersing device. A box 2 is provided on the base 1, a connecting pipe 3 is provided on the box 2, and a feeding box 25 is provided on the connecting pipe 3. The feeding box 25 is provided with multiple rows of equally spaced diversion columns 30. The diversion columns 30 can disperse the pesticide particles when they fall from the bottom of the feeding box 25 into the connecting pipe 3 and the feeding box 25, avoiding the situation where the pesticide particles fall directly and accumulate in the same part of the first screen 12 used for sorting. This ensures the screening effect of the first screen 12 and facilitates the subsequent processing of pesticide particles by the dispersing device.

[0022] The dispersing device includes a drive shaft 4 and a driven shaft 11 rotatably connected to the housing 2, a support 7 mounted on the housing 2, a first motor 8 mounted on the support 7, a first gear 9 and a second gear 10 coaxially mounted on the drive shaft 4 and the driven shaft 11 respectively, a rotating drum 5 coaxially mounted on the drive shaft 4 and the driven shaft 11, and a plurality of dispersing rods 6 arranged in an annular array and distributed axially on the rotating drum 5; the first motor 8 and the drive shaft 4 are drivenly connected, the first gear 9 and the second gear 10 are meshed, and the lower opening of the connecting pipe 3 is located directly above the gap between the drive shaft 4 and the driven shaft 11.

[0023] In this embodiment, when pesticide particles fall evenly from the connecting pipe 3 into the interior of the box 2, the first motor 8 is started to drive the drive shaft 4 to rotate. The drive shaft 4 drives the first gear 9 to rotate. The first gear 9 and the second gear 10 mesh and transmit power, causing the second gear 10 to drive the driven shaft 11 to rotate. In turn, the drive shaft 4 and the driven shaft 11 drive the rotating drum 5 on them to rotate relative to each other. The rotating drum 5 drives the dispersing rod 6 on it to rotate. The dispersing rods 6 on the two rotating drums 5 are alternately distributed in sequence, and the material of the dispersing rods 6 is made of a material with a certain elasticity and smoothness, so as to ensure that the dispersing rods 6 can disperse the pesticide particles while avoiding the pesticide particles from splashing and bouncing. At the same time, the setting of the diversion column 30 greatly reduces the load of the dispersing rods 6 in the same position, ensuring the treatment effect on the agglomerated pesticide particles and having good practicality.

[0024] Example 2

[0025] like Figures 1-3 As shown, the pesticide granule sorting device proposed in this embodiment, compared with the first embodiment, has the following features: the box 2 is provided with a first screen 12 and a second screen 13 inside; the box 2 is provided with three discharge ports 14; the box 2 is provided with a vibration device inside; the vibration device includes two second motors 15 on the box 2, a first rotating rod 16 driven and connected to the second motors 15, two abutting wheels 17 on the first rotating rods 16, two first fixing blocks 18 and a second fixing block 23 on the first screen 12 and the second screen 13, and a support assembly inside the box 2; the abutting wheels 17 and the first fixing blocks 18 are reciprocating abutting each other.

[0026] The support assembly includes two vertically distributed fixed cylinders 19 inside the housing 2, a spring 20 disposed inside the fixed cylinder 19, a telescopic rod 21 disposed on the spring 20 and slidably connected to the fixed cylinder 19, and a top block 22 disposed on the telescopic rod 21; the top block 22 and the second fixed block 23 abut against each other.

[0027] Four symmetrically distributed baffles 24 are provided on both the first screen 12 and the second screen 13. The baffles 24 and the box body 2 are fitted together and slidably connected.

[0028] In this embodiment, after the particles are conveyed onto the first screen 12, two second motors 15 are activated to drive the first rotating rod 16 to rotate. The first rotating rod 16 drives the abutment wheel 17 to rotate. The protrusions on the abutment wheel 17 continuously push and abut against the first fixed block 18 through rotation, thereby causing the first screen 12 and the second screen 13 to vibrate. This causes the particles to be vibrated and sorted. Smaller agglomerated pesticide particles are easily dispersed, while larger-diameter pesticide particles remain on the first screen 12 and are discharged from the upper discharge port 14. Medium- and small-diameter pesticide particles fall onto the screen. On the second screen 13, pesticide particles of the appropriate size remain on the screen and are discharged from the middle discharge port 14. Smaller pesticide particles and some impurities fall to the bottom of the box 2 and are discharged from the lower discharge port 14. If more fine separation of pesticide particles is required, the number of screens can be increased and the size of the screen holes can be adjusted. When vibrating, the second fixed block 23 will continuously squeeze the top block 22. The top block 22 will continuously compress the spring 20 through the telescopic rod 21, thereby reducing the damage to the first screen 12 and the second screen 13 and reducing noise.

[0029] Example 3

[0030] like Figure 1 and Figure 4 As shown, the pesticide particle sorting device proposed in this embodiment, compared with the first embodiment, has a support frame on the base 1, a feeding box 25 on the support frame, and a pre-processing mechanism on the feeding box 25. The pre-processing mechanism includes two third motors 26 on the feeding box 25, a second rotating rod 27 driven and connected to the third motors 26, a fixing frame 28 on the second rotating rod 27, and a plurality of dispersing rods 29 linearly distributed on the fixing frame 28; the second rotating rod 27 is rotatably connected to the feeding box 25.

[0031] In this embodiment, before the pesticide particles are poured onto the top of the feeding box 25, the third motor 26 is started to drive the second rotating rod 27 to rotate. The second rotating rod 27 drives the fixed frame 28 to rotate, and the fixed frame 28 drives multiple dispersing rods 29 to rotate. When the pesticide particles slide to the position of the dispersing rods 29, the dispersing rods 29 will disperse the pesticide particles under the action of rotation, so that the accumulated pesticide particles can be dispersed. This is not only beneficial to the subsequent sorting process, but also avoids the situation where the pesticide particles are easy to have poor flow when passing through the diversion column 30. Thus, the efficiency of subsequent sorting is improved by the pretreatment of pesticide particles.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
