Description

Technical Field

[0001] The utility model relates to the technical field of agricultural instruments, in particular to a new type of bud point applicator. Background Art

[0002] A bud inhibitor is a device used to inhibit the growth of axillary buds of tobacco leaves. Axillary buds are a type of lateral buds. During the growth process of tobacco leaves, axillary buds will inevitably grow. The existence of axillary buds will consume a large amount of nutrients and water, reducing the yield and quality of tobacco leaves. Therefore, the bud inhibitor is used to spray the liquid medicine on the axillary buds in a spot spraying manner to achieve the effect of inhibiting buds and ensure the yield and quality of tobacco leaves.

[0003] Chinese Utility Model Patent CN212013706U discloses a new type of bud inhibitor and a traditional bud point applicator, which is provided with a spraying device matching with the nozzle inside the nozzle. However, this spraying device only functions as a check valve and cannot adjust the internal pressure, thus unable to ensure the normal operation and use safety of the bud point applicator, and unable to avoid affecting the bud point effect or damaging the equipment due to too high or too low pressure. Summary of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a new type of bud point applicator.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A new type of bud point applicator includes a medicine barrel body. The liquid outlet of the medicine barrel body is connected with an input pipeline, and a check valve one is installed on the outer surface of the input pipeline. The other end of the input pipeline is connected with an airbag, the other end of the airbag is connected with an output pipeline, the other end of the output pipeline is connected with a check valve two, and the check valve two also plays a role in preventing the backflow of the liquid medicine to ensure the one-way movement of the liquid medicine. A nozzle is sleeved on the outer surface of the check valve two, and a backflush valve is arranged between the check valve two and the nozzle. The backflush valve is embedded inside the nozzle, and a group of symmetrical circular through holes are arranged on the front side of the front end of the backflush valve.

[0006] The beneficial effect of the utility model is that the backflush valve is arranged inside the nozzle of the utility model, which makes the airbag pressure appropriate, has good controllability, and makes the operation more precise and controllable. It effectively adjusts the pressure inside the airbag body, ensures the normal operation and use safety of the bud point applicator, and avoids affecting the bud point effect or damaging the equipment due to too high or too low pressure.

[0009] In the figure: 1. Medicine bucket body; 2. Input pipeline; 3. Check valve I; 4. Airbag; 5. Output pipeline; 6. Check valve II; 7. Nozzle; 8. Backflush valve. Specific embodiments

[0010] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0011] See Figure 1 - Figure 2 , a new type of bud-pointing device, including a medicine bucket body 1. The liquid outlet of the medicine bucket body 1 is connected to an input pipeline 2. A check valve I 3 is installed on the outer surface of the input pipeline 2 to control the one-way flow of the liquid medicine in the input pipeline 2 and prevent backflow.

[0012] The other end of the input pipeline 2 is connected to an airbag 4, and the airbag 4 is used to store and transport the liquid medicine.

[0013] The other end of the airbag 4 is connected to an output pipeline 5. The other end of the output pipeline 5 is connected to a check valve II 6. The check valve II 6 also plays a role in preventing the backflow of the liquid medicine, ensuring the one-way movement of the liquid medicine. A nozzle 7 is sleeved on the outer surface of the check valve II 6. The nozzle 7 is used to accurately spray the liquid medicine transported from the airbag 4 to achieve the purpose of bud-pointing.

[0014] A backflush valve 8 is provided between the check valve II 6 and the nozzle 7. The backflush valve 8 is embedded inside the nozzle 7. A group of symmetric circular through holes are opened on the front side of the front end of the backflush valve 8. By opening a group of circular through holes on the front side of the front end of the backflush valve 8, the liquid outlet pressure can be effectively adjusted, so that the airbag pressure becomes appropriate, with good controllability and more accurate and controllable operation. The pressure inside the airbag body is effectively adjusted to ensure the normal operation and use safety of the bud-pointing device, and avoid affecting the bud-pointing effect or damaging the equipment due to too high or too low pressure.

[0015] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
