[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This device completes the processing of agglomerated microbial agents through the setting of an anti-caking structure. The motor drives the first synchronous wheel to rotate, and the first synchronous wheel transmits power to the second synchronous wheel through the synchronous belt, which drives the rotating shaft and the eccentric wheel to rotate. When the protruding part of the eccentric wheel rotates to contact the sliding plate, it will push the sliding plate to slide away from the connecting box. At this time, the sliding plate will compress the spring. When the protruding part of the eccentric wheel rotates away from the sliding plate, the spring releases its elastic potential energy, pushing the sliding plate to slide closer to the connecting box and back to the initial position. This process is repeated, which drives the filter box to screen the powdered microbial agents in the storage tank, blocking the agglomerated agents above the filter box. At the same time, the agglomerated agents are broken up by vibration. The stirring rod, driven by the motor, drives several stirring blades to stir the agents in the storage tank, preventing the agents from accumulating and agglomerating at the collection hopper.

[0016] 2. This device completes the dispensing operation of the microbial agent through the dispensing structure. The electric push rod is activated according to the height of the packaging container to adjust the position of the dispensing box so that the distance between the dispensing head and the packaging container is appropriate. The control valve on the dispensing head is opened, and the microbial agent flows continuously into the packaging container located in the connecting sleeve through the dispensing head to realize the dispensing operation. At the same time as dispensing, the blower draws the powdered microbial agent flying in the connecting sleeve into the collection box. The filter screen in the collection box filters the powdered microbial agent in the airflow. The powdered microbial agent is blocked on the filter screen and gradually settles at the bottom of the collection box, while the filtered clean air is discharged from the collection box through the air outlet pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Refer to Figure 1-2 This embodiment provides a negative pressure collection and dispensing device for preventing the flying of powdered microbial agents, including a storage tank 1, a dispensing tank 4, an anti-caking structure, and a dispensing structure. The storage tank 1 is fixedly connected to the top of the dispensing tank 4, a feed pipe 2 is embedded in the top of the storage tank 1, an anti-caking structure is provided inside the storage tank 1, a telescopic hose 19 is provided at the bottom of the storage tank 1, two electric push rods 20 are fixedly connected to the top of the dispensing tank 4, and a dispensing box 21 is fixedly connected to the bottom of the electric push rods 20. The bottom of the telescopic hose 19 is connected to the dispensing box 21, and a dispensing structure is provided at the bottom of the dispensing box 21. Two mounting bases 29 are fixedly connected to the bottom of the storage tank 1.

[0024] The anti-caking structure includes a hopper 3, a stirring rod 5, stirring blades 6, a round rod 15, a sliding plate 16, a spring 17, and a filter box 18. The hopper 3 is fixedly connected to the top of the storage tank 1. The stirring rod 5 is rotatably connected to the top of the storage tank 1 and inside the hopper 3. Several stirring blades 6 are fixedly connected to the stirring rod 5. Two round rods 15 are fixedly connected to the inner side wall of the storage tank 1. Sliding plates 16 are slidably connected to the round rods 15. The filter box 18 is fixedly connected between the two sliding plates 16. Two springs 17 are fixedly connected to the end of the storage tank 1 away from the through groove 14. The other end of the springs 17 is fixedly connected to the sliding plate 16.

[0025] A connecting box 10 is fixedly connected to the outer wall of the storage tank 1, and a rotating shaft 11 is rotatably connected inside the connecting box 10. An eccentric wheel 13 is fixedly connected to the rotating shaft 11. A through groove 14 is opened at one end of the storage tank 1 near the connecting box 10, and the connecting box 10 communicates with the through groove 14. The top end of the stirring rod 5 passes through the storage tank 1 and is fixedly connected to a first synchronous wheel 7. A motor 9 is installed at the top end of the storage tank 1, and the output end of the motor 9 is fixedly connected to the first synchronous wheel 7. The top end of the rotating shaft 11 passes through the connecting box 10 and is fixedly connected to a second synchronous wheel 12. A synchronous belt 8 is provided between the first synchronous wheel 7 and the second synchronous wheel 12.

[0026] In this embodiment, the bacterial agent to be dispensed is added into the storage tank 1 through the feed pipe 2. Then, the motor 9 is started. The output end of the motor 9 drives the first synchronous pulley 7 to rotate. The first synchronous pulley 7 transmits power to the second synchronous pulley 12 through the synchronous belt 8, causing the second synchronous pulley 12 to drive the rotating shaft 11 to rotate within the connecting box 10. The eccentric wheel 13 on the rotating shaft 11 also rotates accordingly. When the protruding part of the eccentric wheel 13 rotates to contact the sliding plate 16, it pushes the sliding plate 16 to slide away from the connecting box 10 along the round rod 15. At this time, the sliding plate 16 compresses the spring 17, which accumulates elastic potential energy. When the protruding part of the eccentric wheel 13 rotates away from the sliding plate 16, the spring 17 releases its elastic potential energy, pushing the sliding plate 16 to slide closer to the connecting box 10 along the round rod 15. Returning to the vicinity of the initial position, this process is repeated, and the slide plate 16 continuously reciprocates on the round rod 15. The filter box 18, which is fixedly connected to the slide plate 16, reciprocates along with the slide plate 16. During the movement, the filter box 18 sieves the powdered microbial agent in the storage tank 1, blocking the clumps of agent above the filter box 18. At the same time, the clumps are broken up by vibration. Meanwhile, the stirring rod 5 rotates under the drive of the motor 9, and the several stirring blades 6 on its surface continuously stir the agent in the storage tank 1, especially the agent near the collection hopper 3, to prevent the agent from accumulating and clumping at the collection hopper 3. After stirring and sieving by the filter box 18, the evenly dispersed agent falls into the bottom of the storage tank 1 through the filter box 18, and then smoothly enters the discharge box 21 through the telescopic hose 19.

[0027] Example 2: Refer to Figure 1-4 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that the dispensing structure includes a dispensing head 22, a connecting sleeve 23, an annular suction pipe 24, a collection box 25, a filter screen 26, a fixing plate 27, a fan 28, and an air outlet pipe 30. The bottom end of the dispensing box 21 is fixedly connected to two connecting sleeves 23, and a dispensing head 22 is provided at the bottom end of the dispensing box 21 and inside the two connecting sleeves 23. A control valve is provided on the dispensing head 22, and an annular suction pipe 24 is provided on the inner side wall of the connecting sleeve 23.

[0028] A collection box 25 is fixedly connected to the bottom of the dispensing box 21 and between the two connecting sleeves 23. A filter screen 26 is installed inside the collection box 25, and an air outlet pipe 30 is installed at the front end of the collection box 25. Fixing plates 27 are fixedly connected to both outer side walls of the collection box 25. A fan 28 is installed at the top of the fixing plate 27. The output end of the fan 28 passes through the connecting sleeve 23 and is connected to the annular suction pipe 24. The output end of the fan 28 is connected to the collection box 25.

[0029] In this implementation, the packaging container is first placed on the mounting base 29. Then, the electric push rod 20 is activated according to the height of the packaging container to adjust the position of the dispensing box 21, so that the distance between the dispensing head 22 and the packaging container is appropriate, facilitating the smooth entry of the microbial agent. Then, the control valve on the dispensing head 22 is opened, and the microbial agent in the dispensing box 21 flows continuously into the packaging container located in the connecting sleeve 23 through the dispensing head 22, realizing the dispensing operation. At the same time as dispensing, the blower 28 is started, and its output end forms a negative pressure environment. Since the output end of the blower 28 is connected to the annular suction pipe 24, the powdered microbial agent flying in the connecting sleeve 23 is agitated by the negative pressure and is then agitated. The suction pipe 24 quickly draws in the airborne microbial agent, which then enters the blower 28 with the airflow and is transported to the collection box 25. The filter screen 26 inside the collection box 25 filters the powdered microbial agent in the airflow. The powdered microbial agent is blocked on the filter screen 26 and gradually settles at the bottom of the collection box 25. The filtered clean air is discharged from the collection box 25 through the exhaust pipe 30. The fixing plate 27 provides stable support for the blower 28, ensuring that the blower 28 will not shake during operation and ensuring the stable operation of the negative pressure collection system. Through this combination, the microbial agent is dispensed and the airborne powder is effectively collected, avoiding waste and pollution.
