Description

Technical Field

[0001] This utility model relates to the field of tomato breeding, and more specifically, to a tomato breeding pollination device. Background Technology

[0002] Tomatoes, as a widely cultivated and important economic crop globally, have breeding efficiency that directly impacts variety improvement and yield enhancement. In tomato hybridization breeding, artificial pollination is a core step, requiring precise transfer of pollen from the male parent to the stigma of the female parent flower to ensure hybridization success. Traditional artificial pollination methods, however, suffer from pollen scattering, low utilization, and are time-consuming and labor-intensive, making them unsuitable for large-scale cultivation. While mechanized pollination equipment, in practical applications, uses high-speed airflow that causes pollen dispersion, making it difficult to focus on the target flower, resulting in poor pollination effects on complex flower types (such as closed flowers and multi-layered flowers). Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a tomato breeding pollination device, including a pollen container for holding pollen and a piston tube for blowing pollen. The front end of the piston tube is provided with a horn tube for spraying pollen. A micro air pump is connected to the rear end of the piston tube. A telescopic auxiliary pressure tube is provided below the piston tube. The rear end of the auxiliary pressure tube is connected to the piston tube, and the front end of the auxiliary pressure tube extends to the bottom of the horn tube. A handle is connected to the bottom of the auxiliary pressure tube.

[0004] In a preferred embodiment, an inner threaded tube is installed at the top of the piston tube, a threaded tube inserted into the inner threaded tube is provided at the bottom of the pollen tank, and a solenoid valve is installed at the bottom of the inner cavity of the inner threaded tube.

[0005] In a preferred embodiment, the piston tube is connected to a buffer tube at its front end, and the horn tube is installed at the front end of the buffer tube.

[0006] In a preferred embodiment, the output end of the micro air pump is equipped with an air tube that extends into the interior of the rear end of the piston tube.

[0007] A semi-circular drainage plate is installed at the top of the piston tube cavity located between the trachea and the inner wire tube.

[0008] In a preferred embodiment, the auxiliary pressure fitting includes a first bend connected to the piston tube, the connection point of the first bend to the piston tube being located directly below the drain plate, a telescopic hose being connected to the front end of the first bend, and a second bend being connected to the front end of the telescopic hose, the front end of the second bend facing the front side of the horn tube.

[0009] In a preferred embodiment, a limiting tube is sleeved on the outside of the second bend, and a bent support rod is connected between the limiting tube and the first bend.

[0010] The handle is fixed to the bottom of the first bend.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This invention extends the pollen flow path and reduces the airflow speed, allowing the pollen to be concentrated and sprayed onto the stigma, thereby improving pollen utilization. By combining the main airflow with the auxiliary lateral airflow, it can "lift" the pollen and the plant, enhance pollen adhesion inside closed flowers, and improve the pollination effect of closed flowers and multi-layered flowers.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0017] like Figure 1-2 The tomato breeding pollination device shown includes a pollen tank 1 for holding pollen and a piston tube 2 for blowing pollen. The front end of the piston tube 2 is provided with a horn tube 3 for spraying pollen. A micro air pump 4 is connected to the rear end of the piston tube 2. A telescopic auxiliary pressure tube is provided below the piston tube 2. The rear end of the auxiliary pressure tube is connected to the piston tube 2. The front end of the auxiliary pressure tube extends to the bottom of the horn tube 3. A handle 5 is connected to the bottom of the auxiliary pressure tube.

[0018] Based on the above, airflow is injected into the piston tube 2 by the micro air pump 4 to form a high-speed airflow channel, which blows the pollen from the piston tube 2 to the trumpet tube 3 and acts on the tomato plant. The auxiliary pressure tube on one side blows the airflow and acts on the tomato flower, forming a lateral airflow that can "lift" the pollen and the plant, make up for the lack of natural wind, and ensure pollination inside the closed flower.

[0019] The piston tube 2 is equipped with an inner threaded tube 6 at the top, and the pollen can 1 is provided with a threaded tube 7 inserted into the inner threaded tube 6 at the bottom. A solenoid valve 8 is installed at the bottom of the inner cavity of the inner threaded tube 6.

[0020] Based on the above, the pollen tank 1 is sealed to the inner threaded tube 6 via the threaded tube 7, and the solenoid valve 8 controls the quantitative release of pollen to the piston tube 2 to avoid over-release or blockage.

[0021] The piston tube 2 is connected to a buffer tube 9 at its front end, and the horn tube 3 is installed at the front end of the buffer tube 9. The buffer tube 9 extends the pollen airflow path and reduces the flow rate through a gradually expanding tube diameter design to prevent pollen from scattering due to inertia and ensure that it is concentrated and sprayed onto the target flower.

[0022] The output end of the micro air pump 4 is equipped with an air tube 10, which extends to the interior of the rear end of the piston tube 2. A semi-circular drainage plate 11 is installed at the top of the inner cavity of the piston tube 2 located between the air tube 10 and the inner wire tube 6.

[0023] Based on the above, the air pipe 10 guides the airflow from the air pump to the rear end of the piston pipe 2, and the semi-circular structure of the guide plate 11 guides the airflow to form a vortex, so that the pollen and air are fully mixed and the uniformity of the spraying is improved.

[0024] The auxiliary pressure fitting includes a first bend 12 connected to the piston tube 2. The connection between the first bend 12 and the piston tube 2 is located directly below the drain plate 11. A telescopic hose 13 is connected to the front end of the first bend 12. A second bend 14 is connected to the front end of the telescopic hose 13. The front end of the second bend 14 faces the front side of the horn tube 3.

[0025] Based on the above, the first bend 12 diverts part of the airflow from below the diversion plate 11 to the telescopic hose 13, and then the second bend 14 blows air onto the flower from the side, enhancing the adhesion of pollen to the stigma and greatly improving the pollination effect for closed flowers and multi-layered flowers.

[0026] The second bend 14 is fitted with a limiting tube 15, and a bent support rod 16 is connected between the limiting tube 15 and the first bend 12. The handle 5 is fixed to the bottom of the first bend 12.

[0027] Based on the above, during operation, the micro air pump 4 injects airflow into the rear end of the piston tube 2 through the air pipe 10, forming a high-speed airflow channel. When the airflow passes through the guide plate 11, the semi-circular structure generates a vortex, which fully mixes the pollen released quantitatively by the solenoid valve 8 in the pollen tank 1. The mixed pollen airflow enters the buffer tube 9, which extends the flow path and reduces the flow rate, preventing the pollen from scattering due to inertia. The decelerated pollen airflow is evenly sprayed from the front end of the trumpet tube 3, directly covering the stigma of the tomato flower. The second curved tube 14 extends to the side of the flower through the telescopic hose 13, and simultaneously releases auxiliary airflow (diverted by the same air pump), pushing the suspended pollen towards the stigma a second time. When facing closed or complex flowers, it can greatly improve the pollination effect. By operating the auxiliary pressure pipe through the handle 5, the spraying angle and distance can be flexibly adjusted to adapt to different plant heights and flower positions. The limiting tube 15 and the support rod 16 maintain the stability of the second curved tube 14, preventing shaking during operation that could cause pollen to shift.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
