Description

Technical Field

[0001] This utility model relates to the field of biological control technology of vegetable rot fungi, specifically a portable integrated device for dispensing and spraying pesticides for the biological control of vegetable rot fungi. Background Technology

[0002] In vegetable cultivation, biological control technology has become an important means of controlling vegetable rot fungi due to its green, environmentally friendly, and safe characteristics. Biological control agents are mostly microbial preparations or their metabolites. Their control effect is closely related to the uniformity of the mixture between the agent and water. Uneven mixing can lead to excessively high or low local agent concentrations, which not only affects control efficiency but may also damage microbial activity and reduce agent efficacy due to excessively high local concentrations.

[0003] In the prior art, portable spraying devices mainly consist of manually inflatable sprayers, whose structure typically includes a storage tank, a manual inflation device, a spray bar, and a nozzle. For example, Chinese utility model patent CN214628794U discloses a constant-pressure inflatable sprayer, including a sprayer body and an inflation cylinder installed inside the sprayer body. When using this sprayer, the biological control agent and water must first be added to the sprayer body, and the sprayer body is manually shaken to achieve preliminary mixing. Then, the mixture is sprayed out through the nozzle by inflation and pressurization. However, the manual shaking mixing method relies on the strength and frequency of manual operation, making it difficult to ensure that the agent and water are fully mixed. Especially for powdered biological control agents, problems such as local clumping or uneven dispersion are prone to occur, directly affecting the consistency of the control effect after spraying.

[0004] Furthermore, in vegetable cultivation, farmers frequently need to move around in the fields. Existing manual air-filled sprayers have low mixing efficiency and poor uniformity, which not only increases the workload for farmers but also leads to pesticide waste and fluctuating control effects due to insufficient mixing. Therefore, considering the characteristics of biological control agents, it is necessary to design a portable integrated mixing and spraying device that can achieve uniform mixing of pesticides and water. Utility Model Content

[0005] The purpose of this invention is to provide a portable integrated spraying and dispensing device for the biological control of vegetable rot fungi, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable integrated spraying device for biological control of vegetable rot fungi, comprising a sprayer, a flushing pipe provided on the body of the sprayer, one end of the flushing pipe being connected to the body of the sprayer, and a rubber stopper being provided inside the flushing pipe in a sliding seal, a stopper rod being fixedly connected to one end of the rubber stopper, and the end of the stopper rod away from the rubber stopper extending from the other end of the flushing pipe; The other end of the flushing pipe is equipped with a locking mechanism for locking the plug rod.

[0007] The top of the flushing pipe is fixedly connected to a feeding pipe for adding biological control agents. A sealing nut is detachably installed at the end of the feeding pipe away from the flushing pipe. The stopper rod can move the rubber stopper inside the flushing pipe between a first extreme position far from the kettle body and a second extreme position close to the kettle body, so as to fully mix the biological control agent with the water in the kettle body.

[0008] Preferably, a fixing plate is fixedly connected to one end of the flushing pipe, the peripheral surface of the fixing plate is sealed to the inner wall surface of the flushing pipe, the fixing plate has a through hole, and the fixing plate is located on the other side of the feeding pipe opposite to the rubber stopper.

[0009] Preferably, the feeding pipe is arranged vertically, with its bottom end extending into the interior of the flushing pipe.

[0010] Preferably, the locking mechanism includes a positioning pin and a pin hole on the plug rod, the positioning pin and the pin hole being matched; one end of the positioning pin is coaxially fixed with a threaded rod, the threaded rod being threadedly connected to the flushing pipe.

[0011] Preferably, a threaded cylinder is fixedly installed on the flushing pipe, the bottom end of the threaded cylinder is flush with the inner wall of the flushing pipe, and the threaded rod threaded through the threaded cylinder.

[0012] Preferably, a handle is fixedly connected to the end of the stopper rod away from the rubber stopper.

[0013] Preferably, one end of the flushing pipe is flush with the inner wall of the kettle body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention features a flushing pipe, a feeding pipe, a rubber stopper, and a stopper rod on the kettle body. After adding the biopesticide, pulling the stopper rod moves the rubber stopper from its second extreme position to its first extreme position. Water from inside the kettle enters the flushing pipe and mixes with the biopesticide in the first stage. Then, pushing the stopper rod pushes the rubber stopper from its first extreme position to its second extreme position, allowing the mixture of biopesticide and water from the flushing pipe to enter the kettle body, achieving a second stage of mixing. In other words, the biopesticide undergoes multiple mixing processes. While a single pull of the rubber stopper yields good mixing, multiple pulls further enhance the effect. The biological control agent and water can be thoroughly and evenly mixed with just a few rubber stoppers, and the mixing speed is fast. At the same time, the fixing plate and the through hole allow water inside the container to enter the flushing pipe through the through hole as the rubber stopper moves to the first extreme position, creating turbulence as the water passes through the through hole. Similarly, as the rubber stopper moves from the first extreme position to the second extreme position, water inside the flushing pipe enters the container through the through hole, also creating turbulence as the water passes through the through hole. This allows the biological control agent and water to be mixed quickly and evenly, ensuring the effectiveness of the biological control agent. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] Please see Figures 1-3 This utility model provides a technical solution: A portable integrated spraying device for the biological control of vegetable rot fungi includes a sprayer 100, which comprises a body 1, a nozzle 2, and an inflation rod 3. In use, inflation is achieved by pulling up and pressing the inflation rod 3. Pressing the inflation rod 3 several times increases the air pressure inside the body 1 to the required value. Then, turning on the sprayer 100 will spray the mixed liquid inside the body 1 through the nozzle 2. The above is all prior art and will not be elaborated further.

[0019] The spray bottle 100 has a water pipe 4 on its body 1. In this embodiment, when the body 1 is placed on the ground, the water pipe 4 is in a horizontal state. The material of the water pipe 4 is not limited here. For example, it can be the same material as the body 1. One end of the water pipe 4 is connected to the body 1, and a rubber stopper 7 is provided inside the water pipe 4 in a sliding seal. One end of the rubber stopper 7 is fixedly connected to a stopper rod 8, and the end of the stopper rod 8 away from the rubber stopper 7 extends out from the other end of the water pipe 4. The position of the rubber stopper 7 inside the water pipe 4 can be adjusted by pushing and pulling the stopper rod 8.

[0020] A handle 9 is fixedly connected to the end of the stopper rod 8 away from the rubber stopper 7. The handle 9 is designed to make it convenient for the user to pull the stopper rod 8.

[0021] In this embodiment, one end of the flushing pipe 4 is flush with the inner wall of the kettle body 1.

[0022] The other end of the flushing pipe 4 is equipped with a locking mechanism for locking the plug rod 8. When the plug rod 8 is locked in place, pressure changes inside the kettle body 1 will not push the rubber stopper 7 away from the kettle body 1 when air is pumped in. In this embodiment, the locking mechanism includes a positioning pin 12 and a pin hole 13 on the plug rod 8. The positioning pin 12 and the pin hole 13 are matched. For example, when the positioning pin 12 is inserted into the pin hole 13, the locking mechanism is in the locked plug rod 8 state. When the positioning pin 12 is withdrawn from the pin hole 13, the plug rod 8 is in a free state. Users can push and pull the stopper rod 8 at will; one end of the positioning pin 12 is coaxially fixed with a threaded rod 14, and the diameter of the positioning pin 12 is smaller than the diameter of the threaded rod 14. A threaded cylinder 6 is fixedly installed on the flushing pipe 4. The material of the threaded cylinder 6 can be consistent with that of the flushing pipe 4. The threaded rod 14 is threadedly connected to the flushing pipe 4 through the threaded cylinder 6. The bottom end of the threaded cylinder 6 is flush with the inner wall surface of the flushing pipe 4. Specifically, in this embodiment, the inner circumferential wall of the flushing pipe 4 is circular. Therefore, the bottom end face of the threaded cylinder 6 is arc-shaped in the axial direction of the flushing pipe 4, and the center of the arc is located on the axis of the flushing pipe 4.

[0023] Furthermore, the fact that the diameter of the positioning pin 12 in the above scheme is smaller than the diameter of the threaded rod 14 can make it easier to remove the positioning pin 12 from the inside of the flushing pipe 4. Then, with the bottom end of the threaded cylinder 6 flush with the inner wall of the flushing pipe 4, it is easy to pull the rubber stopper 7 out of the inside of the flushing pipe 4.

[0024] The top of the flushing pipe 4 is fixedly connected to a feeding pipe 5 for adding biological control agents. A sealing nut 10 is detachably installed at the end of the feeding pipe 5 away from the flushing pipe 4. A sealing ring is provided between the sealing nut 10 and the feeding pipe 5. When the sealing nut 10 is tightened, the sealing ring is squeezed, thereby achieving a sealed connection between the sealing nut 10 and the feeding pipe 5 to prevent water and air leakage. When it is necessary to add biological control agents, simply unscrew the sealing nut 10 and add an appropriate amount of biological control agents into the flushing pipe 4 through the feeding pipe 5.

[0025] The stopper rod 8 can move the rubber stopper 7 inside the flushing pipe 4 between a first extreme position away from the body 1 and a second extreme position close to the body 1, so that the biological control agent is fully mixed with the water in the body 1. Furthermore, in this embodiment, when the rubber stopper 7 moves to the second extreme position, the connection point between the bottom end of the feeding pipe 5 and the flushing pipe 4 is located on the side of the rubber stopper 7 close to the body 1. That is, when the rubber stopper 7 moves between the first and second extreme positions, it will not cause the feeding pipe 5 to be blocked.

[0026] As shown in the figure, in this embodiment, the feeding pipe 5 is vertically arranged, and its bottom end extends into the interior of the flushing pipe 4. On the one hand, the extension of the feeding pipe 5 into the interior of the flushing pipe 4 allows the added biological control agent to enter the middle of the flushing pipe 4, facilitating the mixing of the biological control agent and water inside the flushing pipe 4. On the other hand, the feeding pipe 5 can also be used to limit the position of the rubber stopper 7, that is, when the rubber stopper 7 contacts the feeding pipe 5, the rubber stopper 7 is in the second extreme position. When the threaded rod 14 is in the unlocked stopper rod 8 state, the bottom end of the threaded rod 14 is still partially located inside the flushing pipe 4, so that when the rubber stopper 7 contacts the threaded rod 14, the rubber stopper 7 is in the first extreme position.

[0027] In actual preparation, first adjust the rubber stopper 7 to the second limit position, then fill the container 1 with an appropriate amount of water. At this time, it is important to note that the water level inside the container 1 should be higher than or lower than the top surface of the feeding pipe 5. Then, unscrew the sealing nut 10 and add the biological control agent through the feeding pipe 5. After that, tighten the sealing nut 10. After completion, pull the stopper rod 8 to move the rubber stopper 7 from the second limit position to the first limit position. The water inside the container 1 enters the flushing pipe 4 and mixes with the biological control agent in the first stage. Then, push the stopper rod 8 to push the rubber stopper 7 from the first limit position to the second limit position, so that the mixture of biological control agent and water inside the flushing pipe 4 enters the container 1, realizing the second stage of mixing of the biological control agent. That is, the biological control agent is mixed multiple times. The mixing effect is good when the rubber stopper 7 is pulled out once. Pulling out the rubber stopper 7 several times can achieve a thorough and uniform mixing of the biological control agent and water, and the mixing speed is fast. Alternatively, the required dose of biological control agent can be added in multiple batches through the feeding pipe 5.

[0028] Furthermore, a fixing plate 11 is fixedly connected to one end of the flushing pipe 4. In this embodiment, the fixing plate 11 is circular, and its diameter is equal to the inner diameter of the flushing pipe 4. The circumferential surface of the fixing plate 11 is sealed to the inner wall surface of the flushing pipe 4. A through hole 15 is provided on the fixing plate 11. In this embodiment, the through hole 15 is located at the center of the fixing plate 11. The fixing plate 11 is located on the other side of the feeding pipe 5 relative to the rubber stopper 7.

[0029] Specifically, the fixing plate 11 works in conjunction with the through hole 15. As the rubber stopper 7 moves to the first extreme position, the water inside the kettle body 1 enters the flushing pipe 4 through the through hole 15, causing turbulence as the water passes through the through hole 15. At the same time, as the rubber stopper 7 moves from the first extreme position to the second extreme position, the water inside the flushing pipe 4 enters the kettle body 1 through the through hole 15, also causing turbulence as the water passes through the through hole 15. This allows the biological control agent and water to mix quickly and evenly.

[0030] In the above scheme, by setting a flushing pipe 4, a feeding pipe 5, a rubber stopper 7, and a stopper rod 8 on the kettle body 1, after adding the biological control agent, pulling the stopper rod 8 moves the rubber stopper 7 from the second limit position to the first limit position. Water inside the kettle body 1 enters the flushing pipe 4 and mixes with the biological control agent in the first stage. Then, pushing the stopper rod 8 pushes the rubber stopper 7 from the first limit position to the second limit position, allowing the mixture of biological control agent and water inside the flushing pipe 4 to enter the kettle body 1, achieving a second stage of mixing of the biological control agent. In other words, the biological control agent is mixed multiple times. The mixing effect is good when the rubber stopper 7 is pulled out and pulled out several times. The rubber stopper 7 ensures thorough and uniform mixing of the biological control agent and water, with a rapid mixing speed. Simultaneously, the fixing plate 11, in conjunction with the through hole 15, allows water inside the vessel body 1 to enter the flushing pipe 4 through the through hole 15 as the rubber stopper 7 moves towards the first extreme position, creating turbulence as the water passes through the through hole 15. Similarly, as the rubber stopper 7 moves from the first extreme position to the second extreme position, water inside the flushing pipe 4 enters the vessel body 1 through the through hole 15, again creating turbulence as the water passes through the through hole 15. This rapid and uniform mixing of the biological control agent and water guarantees the effectiveness of the biological control agent.
