When the vertical pipe 304 moves upward, the granular pesticide in the storage bucket 301 enters from the opening at the upper part of the vertical pipe 304, and is discharged onto the second sieve plate 103 through the opening at the lower part of the vertical pipe 304. The second spring 306 pushes the support member 303 to move downward and reset, so that the vertical pipe 304 moves downward. By continuously moving the support member 303 back and forth up and down, the vertical pipe 304 drives the second sieve plate 103 and the third sieve plate 104 to vibrate up and down, and at the same time controls the quantitative feeding of the vertical pipe 304, thereby improving the effect of the equipment on vibration drying and quantitative delivery of granular pesticide preparations.

[0052] Example 3

[0053] A granular pesticide preparation drying process of the present invention comprises the following steps:

[0054] S1, putting the granular pesticide that needs to be dried after granulation into the storage hopper 301 for storage;

[0055] S2, the granular pesticide in the storage hopper 301 is transported to the first box 101 for vibration by quantitative feeding, and hot air is sent into the first box 101 at the same time, so that the hot air dries the granular pesticide during the vibration and transportation process during the upward flow in the first box 101, and the rising hot air transports the powder generated by the vibration of the granular pesticide, so that the hot and humid air and the powder enter the recovery device together, and the granular pesticide after being formed in the first box 101 enters the transport device for standby;

[0056] S3, adding clean water into the recovery device, the hot and humid air and the powder enter the recovery device together and mix with the water to form a slurry, and the slurry is mixed and stirred at the same time;

[0057] S4, transporting the granular pesticide in the transport device to the first tank body 105, and sending hot air to the bottom of the first tank body 105, so that the hot air blows the granular pesticide in the first tank body 105 to agitate boiling and secondary drying;

[0058] S5, spraying the slurry in the recovery device into the first tank 105 to mix with the agitated granular pesticide, so that the slurry is coated on the surface of the granular pesticide, and secondary synthesis is achieved after drying;

[0059] S6. When the air in the first tank body 105 is discharged to the outside, the fine powder mixed in the air is filtered and intercepted by the second filter screens 208 in the two groups of cylinders 205. By alternately exhausting the two groups of cylinders 205 and vibrating the two groups of second filter screens 208, the powder attached to the bottom of the second filter screens 208 is vibrated and falls off, thereby realizing the secondary recycling of the powder.

[0060] like Figures 1 to 14As shown, a granular pesticide preparation drying device and process of the present invention, when working, the granular pesticide to be dried after granulation is conveyed into the first box body 101 through the feeding device, and the granular pesticide entering the first box body 101 falls to the top of the second screen plate 103, and is guided and conveyed by the second screen plate 103 so that the granular pesticide falls on the third screen plate 104, and then the granular pesticide is guided and conveyed by the third screen plate 104 and discharged onto the first screen plate 102, and the feeding device conveys the granular pesticide into the first box body 101 while driving the second screen plate 103 and the third screen plate 104 to vibrate, so that the second screen plate 10 3 and the third screen plate 104 vibrate the granular pesticide, and at the same time, hot air is sent into the first box body 101 from the lower part, so that the hot air dries the granular pesticide during the upward flow in the first box body 101, and the rising hot air conveys the powder generated by the vibration of the granular pesticide, so that the moist hot air and the powder enter the recovery device together to form a slurry, and the first screen plate 102 discharges the dried and shaped granular pesticide to the conveying device, and the granular pesticide is conveyed to the first tank body 105 by the conveying device, and then the slurry is conveyed to the first tank body 105 and mixed with the granular pesticide, so that the secondary synthesis device performs secondary synthesis of the granular pesticide and the slurry.

[0061] The main functions achieved by the present invention are: reducing the adhesion between particles and the breakage of finished granular pesticides by vibrating the granular pesticides, thereby improving the processing quality of granular pesticide preparations; improving the convenience and recycling rate of powder fragments by pulping the powder, and improving the drying and processing efficiency of granular pesticides.

Technical personnel in the industry only need to install and operate them according to the accompanying instruction manual, without the need for technical personnel in this field to make creative efforts.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
