Description

Technical Field

[0001] This utility model belongs to the field of pollen spraying, specifically relating to a pneumatic pollen spraying device with orifice metering. Background Technology

[0002] With the development of modern agricultural technology, pollen spraying has become one of the important methods for plant propagation and pollination. Pollen spraying devices play a key role in agriculture, horticulture, and plant research, especially in hybridization breeding, seedless fruit production, and improving pollination efficiency. While existing pollen spraying devices can complete basic dry powder spraying tasks, problems remain, including significant pollen waste, large and heavy equipment size, and difficulty in carrying and moving the equipment. Furthermore, due to the small size and stickiness of pollen particles, they easily absorb moisture and clump in humid environments. The pipes and nozzles of the sprayer are also relatively narrow, allowing pollen to accumulate and clog these areas, affecting the normal operation of the sprayer.

[0003] Based on the above problems, this utility model discloses a pneumatic pollen spraying device with orifice metering. The device has a simple structure, is lightweight and easy to carry and move. In addition, the pollen feeder is specially designed to address the problem of pollen accumulation and blockage, which effectively improves the problem of pollen accumulation and blockage. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a pneumatic pollen spraying device with a perforated metering system, comprising a pollen bottle; an air outlet pipe is connected to the top of the pollen bottle;

[0006] A pollen inlet pipe is connected to the side of the pollen bottle; a sealing ring is installed on the side wall of the pollen bottle, and one end of the pollen inlet pipe passes through the sealing ring and extends to be connected to an air inlet pipe.

[0007] The pollen bottle is fitted with a stopper at the top, and the stopper has a vent hole.

[0008] As a further improvement of this utility model, the vent is filled with fine sponge in the upper and lower layers and desiccant in the middle layer.

[0009] As a further improvement of this utility model, the powder inlet pipe also includes an inner pipe connected to it. The inner pipe has two rings of evenly distributed, staggered circular holes at its center. The internal channel of the air inlet end of the inner pipe is frustum-shaped. An outer cover is fitted over the inner pipe. The outer cover is a cylindrical sleeve. Six connecting rods are evenly distributed around the outside of the inner pipe. The outer cover is connected to the inner pipe through the six evenly distributed connecting rods.

[0010] As a further improvement of this utility model, an air pump is installed on the side of the air intake pipe.

[0011] As a further improvement of this utility model, a pollen cover is provided at the top of the air outlet pipe.

[0012] As a further improvement of this utility model, the lower half of the pollen cover forms a cylindrical cavity, and the upper half forms an inverted frustum-shaped cavity; the connecting part of the pollen cover adopts a smooth curved surface transition.

[0013] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0014] This utility model's orifice-type metering pneumatic pollen spraying device, in practical use, ensures that the air pressure inside and outside the pollen bottle is the same through the vent hole on the pollen bottle stopper.

[0020] 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.

[0021] Example

[0022] Depend on Figure 1-3 A pneumatic pollen spraying device with a perforated metering system is provided, comprising a pollen bottle 5; an air outlet pipe 2 is connected to the top of the pollen bottle 5.

[0023] A pollen inlet pipe 6 is connected to the side of the pollen bottle 5; a sealing ring 7 is installed on the side wall of the pollen bottle 5, and one end of the pollen inlet pipe 6 passes through the sealing ring 7 and extends to be connected to an air inlet pipe 8.

[0024] The pollen bottle 5 is fitted with a pollen bottle stopper 3 at the top, and a vent hole 4 is provided inside the pollen bottle stopper 3.

[0025] In this embodiment, during actual use, the air pressure inside and outside the pollen bottle 5 can be kept the same through the vent hole 4 on the pollen bottle stopper 3. At the same time, the vent hole 4 is filled with fine sponge and desiccant, which can effectively prevent the pollen from floating out of the pollen bottle 5 when the pollen is sprayed out, thus avoiding the problem of pollen waste. It also prevents moisture in the air from entering the pollen bottle 5, thus preventing the pollen from condensing into lumps and blocking the pollen inlet hole 12.

[0026] Furthermore, the pollen spraying device of this application has a small overall size and light weight, making it easy for users to carry and move; at the same time, its structure is simple, easy to operate, and convenient for users to maintain.

[0027] Specifically, refer to Figure 1-2 The vent 4 is filled with two layers of fine sponge inside, and a desiccant is filled in the middle layer.

[0028] In this embodiment, during use, the desiccant in the middle layer can effectively absorb moisture near the pollen bottle stopper 3, keeping the pollen bottle 5 dry overall and preventing moisture from affecting the pollen; at the same time, the desiccant ensures the flowability and uniformity of pollen during spraying, improving the quality and stability of spraying.

[0029] Specifically, refer to Figure 2 The powder inlet pipe 6 also includes an inner pipe 10 connected to it. The inner pipe 10 has two rings of evenly distributed, staggered circular holes in the center. The internal channel of the air inlet end of the inner pipe 10 is frustum-shaped. An outer cover 11 is fitted over the inner pipe 10. The outer cover 11 is a cylindrical sleeve. Six connecting rods 13 are evenly distributed on the outside of the inner pipe 10. The outer cover 11 is connected to the inner pipe 10 through the six evenly distributed connecting rods 13.

[0030] In this embodiment, as in the specific implementation Figure 2 and Figure 3 As shown, the cylindrical sleeve-shaped outer cover 11 provided outside the pollen inlet 12 can effectively prevent a large amount of pollen from accumulating at the pollen inlet 12, thus preventing the pollen inlet 12 from becoming blocked. At the same time, by changing the size of the pollen inlet 12, the amount of pollen sprayed can be controlled, thereby realizing the function of pollen metering.

[0031] It should be noted that, as in the embodiments Figure 2 As shown, the outer cover 11 and the powder inlet hole 12 are both located outside the powder inlet pipe 6, while the entire structure is located inside the pollen bottle 5.

[0032] Specifically, refer to Figure 1-3 An air pump 9 is installed on the side of the air intake pipe 8.

[0033] In this embodiment, during actual use, after the pollen spraying work begins, the user aligns the pollen hood 1 with the flower. At this time, the air pump 9 outputs an airflow with a certain speed according to the pollen demand. After the airflow is output from the air pump 9, it enters the air inlet pipe 8 and passes through the side round hole of the pollen bottle 5 along the air inlet pipe 8. Through the nested sealing ring 7 set on the pollen bottle 5, the pollen can be prevented from flowing out through the gap between the pollen bottle 5 and the air inlet pipe 8. Then the airflow can flow into the pollen inlet pipe 6.

[0034] Specifically, refer to Figure 1-3 The top of the air outlet pipe 2 is connected to a pollen cover 1.

[0035] In this embodiment, the pollen cover 1 can be used to cover the flowers, thereby preventing pollen from flying around or being sprayed in the wrong place during spraying.

[0036] Specifically, refer to Figure 1-2 The lower half of the pollen cover 1 has a cylindrical cavity, and the upper half has an inverted frustum-shaped cavity; the connecting part of the pollen cover 1 adopts a smooth curved surface transition.

[0037] In this embodiment, the pollen hood 1 has a cylindrical cavity in the lower half and an inverted frustum-shaped cavity in the upper half, which can be used to control the pollen spraying range. At the same time, the pollen bottle stopper 3 has a vent hole 4, which can ensure that the air pressure inside and outside the pollen bottle 5 is the same.

[0038] This utility model relates to a perforated metering pneumatic pollen spraying device:

[0039] Step 1: The initial setup is as follows: the air pump 9 has no airflow output, and the entire device is in a static state, as shown in the specific embodiment. Figure 1 As shown, after the work begins, the pollen hood 1 is aligned with the flower, and the air pump 9 outputs an airflow with a certain speed according to the pollen demand. The airflow enters the air inlet pipe 8 after being output from the air pump 9, and at the same time passes through the side round hole of the pollen bottle 5 along the air inlet pipe 8 until it enters the pollen bottle 5.

[0040] Step 2: After the airflow passes through the air inlet pipe 8, it can flow through the pollen bottle 5 into the pollen inlet pipe 6. By designing a frustum-shaped cavity at the air inlet end of the pollen inlet pipe 6, the negative pressure at the pollen inlet hole 12 can be effectively increased by utilizing Bernoulli's principle, thereby effectively drawing in pollen. A cylindrical sleeve-shaped outer cover 11 is set outside the pollen inlet hole 12 to prevent a large amount of pollen from accumulating at the pollen inlet hole 12, which would cause the pollen inlet hole 12 to become blocked. At the same time, by changing the size of the pollen inlet hole 12, the amount of pollen sprayed can be controlled, thereby realizing the pollen metering function. When the airflow passes through the pollen inlet pipe 6, it will also carry a large amount of pollen into the air outlet pipe 2, and finally spray the pollen out at the pollen cover 1 through the central hole of the pollen bottle stopper 3 along the air outlet pipe 2.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
