Abstract
Description
Technical Field
[0001] The invention relates to the technical field of pesticide pulverization, and in particular to air flow pulverization equipment for processing powdered pesticides. Background Art
[0002] The original pesticide cannot be used directly. It must be processed and prepared into various types of preparations before it can be used. The form of the preparation is called dosage form. Commercial pesticides are sold to users in the form of a certain dosage form. The most commonly used dosage forms in my country are emulsifiable concentrates, suspensions, wettable powders, powders, granules, aqueous solutions, poison baits, mother liquids, mother powders, etc. There are more than ten dosage forms. Powders have the longest history of application. Powders are the most produced and widely used dosage forms in pesticide preparations. Powders are easy to manufacture and use. The original pesticide and inert fillers (talcum powder, clay, kaolin, diatomaceous earth, acid white clay, etc.) are mixed and crushed in a certain proportion to make the powder particle fineness reach a certain standard. Because it is easy to use and does not require water, it can be directly sprayed on crops with a simple powder sprayer. It has high work efficiency, low adhesion on crops, less residue, and is not easy to cause pesticide damage. In addition to being used directly for powder spraying, it can also be used for seed mixing, soil treatment, and preparation of poison bait granules to prevent and control diseases, insects, and weeds. Since most of them are used through dusters, the powder particle fineness needs to meet a certain standard. Ordinary crushing equipment is difficult to achieve a certain standard of powder particle fineness when crushing powders, and more and more powder will adhere to the surface of parts after long-term use, resulting in a gradual decrease in crushing efficiency. Therefore, we proposed an air flow crushing equipment for powder pesticide processing. Summary of the invention

When in use, the powder pesticide is poured from the oblique connecting tube 3 into the circular empty shell 1. After pouring, the threaded round block 4 is manually rotated to threadably cooperate with the inner wall of the oblique connecting tube 3 for installation. The threaded round block 4 blocks the feed port of the oblique connecting tube 3, and the air pump 6 is started to supply air to the circular long shell 501. The gas in the circular long shell 501 passes through the inner cleaning mechanism 503 and is ejected to the outside at high pressure through the conical nozzle 505. The high-pressure ejected airflow crushes the powder pesticide in the circular empty shell 1 with high-pressure airflow. The small circular holes 506 on the outer surface of the conical nozzle 505 facilitate the high-pressure ejection of the airflow around the conical nozzle 505. At the same time, the inside of the circular empty shell 1 When the gas is blown into the conical nozzle 505, the gas pushes the small belt 507 to gradually stretch into the conical nozzle 505. When the small belt 507 stretches, it drives the fine thorn strip 508 on one side to move together. The fine thorn strip 508 gradually penetrates into the gas port of the conical nozzle 505 as the small belt 507 stretches. At the same time, when the fine thorn strip 508 moves, it drives the fine swing thorn 509 on the surface to move together. As the fine thorn strip 508 moves, the fine swing thorn 509 is in contact with the inner wall of the conical nozzle 505 at all times and intermittently punctures the small circular hole 506. At the same time, the powerful jet of the air pump 6 drives the internal cleaning mechanism 503 to move downward gradually until it contacts the blocking mechanism 502 at the bottom of the circular long shell 501 and drives the blocking mechanism 502 to move downward. At this time, the sealing mechanism 503 is The blocking mechanism 502 releases the blockage of the outer oblique circular hole 504, and the pesticide accidentally dropped into the circular long shell 501 falls downward and is discharged through the outer oblique circular hole 504. When the inner cleaning mechanism 503 moves downward, it pushes the conical blocking block 5024 to move downward and release the blockage of the outer oblique circular hole 504. When the conical blocking block 5024 moves downward, it drives the bottom circular plate 5022 to move together. When the bottom circular plate 5022 moves downward, it drives the top pull-back spring 5021 to stretch downward. At the same time, the pesticide discharged downward from the outer oblique circular hole 504 on the bottom circular plate 5022 falls downward through the top circular hole 5023. When the air pump 6 is turned off, the inner cleaning mechanism 503 loses the driving force to move upward, and the pull-back spring 5021 drives the bottom circular plate 5022 to move upward through the pull-back force.When the bottom circular plate 5022 moves back upward, it drives the top conical block 5024 to move together. The conical block 5024 moves upward and enters the outer oblique circular hole 504 to block the outer oblique circular hole 504. When the conical block 5024 moves upward, it drives the semi-arc scrapers 5025 on both sides to move together. When the semi-arc scrapers 5025 move, they contact the surface of the pull-back spring 5021. The semi-arc scrapers 5025 move and scrape the pull-back spring 5021. At the same time, the semi-arc scrapers 5025 scrape The pesticides fall downward through the small circular holes 5026 on the surface, and the powerful spray force of the air pump 6 blows the circular scraper 5033 downward, which drives the top pull-up spring 5032 to stretch downward. When the circular scraper 5033 moves, the outer surface of the circular scraper 5033 is always in contact with the inner wall of the circular long shell 501. When the circular scraper 5033 moves, it slides and scrapes the inner wall of the circular long shell 501. At the same time, the ventilation circular hole 5035 on the top of the circular scraper 5033 facilitates the airflow and the falling pesticides. When the pesticide passes through, the circular scraper 5033 moves, driving the bottom top rod 5034 and the inner oblique arc piece 5036 to move together. The bottom top rod 5034 moves downward until it contacts the conical block 5024 and pushes the conical block 5024 downward to the bottom of the outer oblique circular hole 504. At the same time, the inner oblique arc piece 5036 moves downward until it contacts the bottom of the inner wall of the circular long shell 501 and is squeezed by the circular scraper 5033 to bend inward. When the inner oblique arc piece 5036 bends inward, it pushes the circular long shell 501. The surface of the bottom of the inner wall not covered by the outer oblique circular hole 504 is scraped by sliding, and the inner oblique arc piece 5036 is squeezed and bent until the two sides are respectively in contact with the circular scraper 5033 and the bottom of the inner wall of the circular long shell 501. At this time, the arc surface circular hole 5037 covering the inner oblique arc piece 5036 with a large area is aligned with the ventilation circular hole 5035, which facilitates the air flow to continue to pass through the outer oblique circular hole 504. After the air pump 6 is turned off, the upper pull spring 5032 contracts upward through the pullback force and pulls the circular scraper 5033 back upward.

When in use, the electric telescopic rod 701 is used to The extension of the telescopic rod 701 pushes the annular scraper 703 at the bottom to move downward. When the annular scraper 703 moves downward, it slides and scrapes the inner wall of the circular empty shell 1 and the surface of the dustproof circular plate 2. The adhered pesticide scraped by the annular scraper 703 falls downward through the inclined circular hole 704 opened on the surface. When the annular scraper 703 moves, it drives the curved thorn bar 705 at the bottom to move together. When the curved thorn bar 705 moves to the inside of the oblique connecting tube 3, it swings downward and pierces into the oblique connecting tube 3. The curved thorn bar 705 pierces the inside of the oblique connecting tube 3. After cleaning, the annular scraper 703 is driven to move upward by the contraction of the electric telescopic rod 701. The corrugated ring piece 702 mounted on the electric telescopic rod 701 cooperates with the extension and contraction of the electric telescopic rod 701 to surround and cover the driving shaft of the electric telescopic rod 701.
[0016] When the present invention is operated and used, the powder pesticide is poured into the circular empty shell 1 from the oblique connecting tube 3. After the pouring is completed, the threaded round block 4 is manually rotated to threadably cooperate with the inner wall of the oblique connecting tube 3 for installation. The threaded round block 4 blocks the feed port of the oblique connecting tube 3, and the air pump 6 is started to supply gas to the circular long shell 501. The gas in the circular long shell 501 passes through the inner cleaning mechanism 503 and is ejected outward at high pressure through the conical nozzle 505. The high-pressure ejected airflow crushes the powder pesticide in the circular empty shell 1 with high-pressure airflow. The fine circular holes 506 on the outer surface of the conical nozzle 505 facilitate the high-pressure ejection of the airflow around the conical nozzle 505. At the same time, when the gas in the circular empty shell 1 is blown to flow into the conical nozzle 505, the gas pushes the small belt 507 to gradually move toward the conical nozzle 505. The nozzle 505 is stretched, and the small belt 507 is stretched, and the fine thorn strip 508 on one side is moved together. The fine thorn strip 508 gradually penetrates into the air port of the conical nozzle 505 as the small belt 507 is stretched. At the same time, the fine thorn strip 508 moves, and the fine swing thorn 509 on the surface is moved together. As the fine thorn strip 508 moves, the fine swing thorn 509 is in contact with the inner wall of the conical nozzle 505 at all times and intermittently punctures the small circular hole 506. At the same time, the powerful jet of the air pump 6 pushes the inner cleaning mechanism 503 to move downward gradually until it contacts the blocking mechanism 502 at the bottom of the circular long shell 501 and pushes the blocking mechanism 502 to move downward. At this time, the blocking mechanism 502 releases the blocking of the external oblique circular hole 504, and the pesticide accidentally falling into the circular long shell 501 passes through the outer The oblique circular hole 504 falls downward and is discharged. When the inner cleaning mechanism 503 moves downward, it pushes the conical blocking block 5024 to move downward to release the blocking of the outer oblique circular hole 504. When the conical blocking block 5024 moves downward, it drives the bottom circular plate 5022 to move together. When the bottom circular plate 5022 moves downward, it drives the top pull-back spring 5021 to stretch downward. At the same time, the pesticide discharged downward by the outer oblique circular hole 504 on the bottom circular plate 5022 falls downward through the top circular hole 5023. When the air pump 6 is turned off and the inner cleaning mechanism 503 loses the driving force and moves upward, the pull-back spring 5021 drives the bottom circular plate 5022 to move upward through the pull-back force. When the bottom circular plate 5022 moves upward, it drives the top conical blocking block 5024 to move together. The conical blocking block 5024 moves upward The conical block 5024 moves upward and drives the semi-arc scrapers 5025 on both sides to move together. The semi-arc scrapers 5025 contact the surface of the pull-back spring 5021 when moving, and the semi-arc scrapers 5025 move and scrape the pull-back spring 5021. At the same time, the pesticide scraped by the semi-arc scrapers 5025 falls downward through the small circular holes 5026 on the surface. The powerful spray force of the air pump 6 blows the circular scraper 5033 downward, and the circular scraper 5033 moves downward to drive the top pull-up spring 5032 to stretch downward. When the circular scraper 5033 moves, the outer surface is always in contact with the inner wall of the circular long shell 501. When the circular scraper 5033 moves, it slides and scrapes the inner wall of the circular long shell 501.At the same time, the ventilation hole 5035 opened on the top of the circular scraper 5033 facilitates the passage of airflow and dropped pesticides. When the circular scraper 5033 moves, it drives the bottom top rod 5034 and the inner oblique arc piece 5036 to move together. The bottom top rod 5034 moves downward until it contacts the conical block 5024 and pushes the conical block 5024 downward to the bottom of the outer oblique circular hole 504. At the same time, the inner oblique arc piece 5036 moves downward until it contacts the bottom of the inner wall of the circular long shell 501. The circular scraper 5033 is squeezed and bent inwardly, and the inner oblique arc piece 5036 is slid and scraped on the surface of the bottom of the inner wall of the circular long shell 501 that is not covered by the outer oblique circular hole 504 when bending inwardly. The inner oblique arc piece 5036 is squeezed and bent until the two sides are respectively in contact with the circular scraper 5033 and the bottom of the inner wall of the circular long shell 501. At this time, the arc surface circular hole 5037 covering a large area of the inner oblique arc piece 5036 is aligned with the ventilation circular hole 5035, so that the airflow continues to pass through the outer oblique circular hole 504. The hole 504 is formed. After the air pump 6 is turned off, the pull-up spring 5032 contracts upward through the pull-back force and pulls the circular scraper 5033 upward. The electric telescopic rod 701 is extended to push the annular scraper blade 703 at the bottom to move downward. When the annular scraper blade 703 moves downward, it slides and scrapes the inner wall of the circular shell 1 and the surface of the dustproof circular plate 2. The adhered pesticide scraped by the annular scraper blade 703 falls downward through the inclined circular hole 704 opened on the surface. When the annular scraper blade 703 moves, it drives the curved thorn bar 705 at the bottom to move together. When the curved thorn bar 705 moves to the inside of the oblique connecting tube 3, it swings downward and pierces into the oblique connecting tube 3. The curved thorn bar 705 pierces the inside of the oblique connecting tube 3. After cleaning, the electric telescopic rod 701 is contracted to drive the annular scraper blade 703 to move upward. The corrugated ring piece 702 sleeved on the electric telescopic rod 701 cooperates with the extension and contraction of the electric telescopic rod 701 to surround and cover the driving shaft of the electric telescopic rod 701.
