Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, and in particular to a pollinator for tomato hybridization. Background Technology

[0002] Tomato hybridization refers to the process of artificially interbreeding two tomato parents (father and mother) with different genetic backgrounds to produce hybrid offspring (i.e., F1 generation seeds) that possess the superior traits of both parents. Its core objective is to utilize hybrid vigor (such as high yield, disease resistance, and improved quality). For example, the Riesling tomato achieved a 14%-16% increase in yield compared to the control variety through hybridization. The production of hybrid seeds requires strict isolation of the parents and control of the pollination source throughout the process to ensure the homozygosity of the offspring's genotype and the stability of its traits.

[0003] Traditional pollination methods often involve manually applying pollen to the stigma using a brush, cotton swab, or feather. The effectiveness of manual pollination heavily relies on the operator's skill, and problems such as insufficient pollen collection and uneven application can easily occur, leading to poor stigma coverage. Some stigmas may fail to fertilize due to insufficient pollen, directly increasing the rate of deformed fruit. Furthermore, the repeated manual pollination process inevitably results in mixing of pollen from different varieties. Some operators use manual pollinators, which atomize pollen using air pressure. This not only leads to high pollen waste but also makes it difficult to precisely control pollen distribution, easily contaminating non-target flowers and leaves, thus resulting in low pollination efficiency. Therefore, we urgently need a pollinator specifically designed for tomato hybridization to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low efficiency, uneven pollination, and high manual labor intensity in the existing pollination process, and to propose a pollinator for tomato hybridization.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pollinator for tomato hybridization includes a handle and a vibrating motor installed inside the handle. The output end of the vibrating motor is fixedly connected to a connecting shaft, and the end of the connecting shaft extends outward beyond the handle. The device also includes: a detachable brush head for pollination installed on the connecting shaft, wherein the connecting shaft and the brush head vibrate when the vibrating motor is working; and a detachable storage section for loading pollen installed on the handle.

[0006] For storing and discharging pollen, preferably, the storage unit includes a bracket fixedly mounted on the handle, a storage box for storing pollen fixedly connected to the bracket, and a discharge box for discharging pollen fixedly mounted on the brush head. A connecting pipe is fixedly connected to the storage box, and the end of the connecting pipe is detachably connected to the feed inlet of the discharge box. When the vibrating motor operates, a discharge channel is formed between the storage box and the discharge box. To allow pollen to enter the brush head, the bottom wall of the discharge box is further provided with several discharge holes for discharging pollen, and the discharge holes extend downward and are connected to the brush head.

[0007] To further provide a seal, the feed end of the storage box is secured with an end cap for sealing via an elastic cord.

[0008] To avoid excessive pollen discharge, the diameter of the discharge hole is preferably in the range of 0.3mm-0.5mm.

[0009] For effective pollen adhesion and dispersion, preferably, the length of the bristles on the brush head is in the range of 5mm-8mm.

[0010] Compared with the prior art, this utility model provides a pollinator for tomato hybridization, which has the following beneficial effects: 1. This tomato hybrid pollinator uses a vibrating motor to drive the brush head to vibrate, allowing pollen to fall quickly and evenly from the pollination brush head. Compared with traditional manual brush pollination, it greatly improves the pollination speed and reduces the intensity of manual labor. The vibration makes the pollen more evenly distributed on the pollination brush head, and it can be more comprehensive when in contact with the stigma, improving the pollination success rate and helping to ensure the quality and yield of the tomato hybrid offspring.

[0011] 2. This tomato hybrid pollinator combines pollen storage with a vibration device, resulting in a simple structure. Operators only need to hold the handle, align the brush head with the tomato stigma, and start the vibration motor to complete the pollination operation. It is easy to master and reduces the skill requirements for operators. Furthermore, the storage box is detachable for easy pollen addition, and the transparent material makes it easy to observe the remaining pollen, preventing insufficient pollen from affecting the pollination work.

[0012] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model improves pollination efficiency, ensures the uniformity of pollination, and simplifies the operation of the equipment by concentrating functions. It also allows for intuitive observation of the remaining pollen, avoiding the impact of insufficient pollen on pollination work. Attached Figure Description

[0017] Example: Reference Figures 1-5 A pollinator for tomato hybridization includes a handle 1 and a vibrating motor 2 installed inside the handle 1. The output end of the vibrating motor 2 is fixedly connected to a connecting shaft 3, and the end of the connecting shaft 3 extends outward to the outside of the handle 1. Here, the handle 1 is made of lightweight plastic material, and its interior is hollow to facilitate the installation of other components. The outer surface of the handle 1 is provided with anti-slip texture for easy handling by the operator. The handle 1 is 15cm long, 3cm in diameter, and the depth of the anti-slip texture on the outer surface is 0.5mm. Furthermore, a drive unit is provided inside the handle 1. In addition to the vibration motor 2, the drive unit also includes a drive controller. The controller is used to control the start, stop and vibration frequency of the vibration motor 2. The vibration motor 2 is a DC vibration motor with a power of 3-5W, preferably a 370 DC vibration motor with a power of 4W, which can provide a suitable vibration intensity. The controller uses an STM32 microcontroller as the control core, which can realize the adjustment of the vibration frequency in the range of 50-100Hz. Furthermore, the connecting shaft 3 is made of stainless steel, which has good rigidity and toughness, and can stably transmit the vibration of the vibration motor 2 to the brush head 4. The diameter of the connecting shaft 3 is 5mm and the length is 3cm.

[0018] It also includes the disassembly and assembly of a brush head 4 for pollination mounted on the connecting shaft 3. The brush head 4 has a bristle length ranging from 5mm to 8mm. When the vibration motor 2 is working, the connecting shaft 3 and the brush head 4 vibrate accordingly. Here, the brush head 4 is made of soft nylon bristles, and the bristle length is preferably 6mm, which can ensure the effective adhesion and scattering of pollen, and avoid damaging the stigma of the tomato flower during the pollination process.

[0019] A detachable storage section for loading pollen is installed on the handle 1. The storage section includes a bracket 5 fixedly installed on the handle 1. A storage box 6 for storing pollen is fixedly connected to the bracket 5. An end cap 10 for sealing is fixedly installed on the feed end of the storage box 6 by an elastic rope. A discharge box 7 for discharging is fixedly installed on the brush head 4. Several discharge holes 9 for discharging are opened on the bottom wall of the discharge box 7. The discharge holes 9 penetrate downward and are connected to the brush head 4. The diameter of the discharge holes 9 is in the range of 0.3mm-0.5mm. A connecting pipe 8 is fixedly connected to the storage box 6. The end of the connecting pipe 8 is detachably installed from the feed end of the discharge box 7. When the vibration motor 2 is working, a discharge channel is formed between the storage box 6 and the discharge box 7. Here, both the storage box 6 and the discharge box 7 are transparent plastic boxes. The storage box 6 can be bolted to the handle 1, and the inner bottom wall of the storage box 6 is designed with three inclined sides to avoid pollen accumulation. The connection between the connecting pipe 8 and the discharge box 7 can be connected by a buckle or flange, and the connecting pipe 8 is set at an inclination. When the vibration motor 2 is started, the vibration force will be transmitted to the storage box 6, and the pollen will be discharged into the discharge box 7 through the connecting pipe 8. Then, the vibration can be used to make the pollen quickly enter the bristles of the brush head 4. Furthermore, the diameter of the discharge hole 9 is preferably 0.4 mm, and the discharge hole 9 is distributed in the gap between the brushes of adjacent brush heads 4.

[0020] It should be noted that a power supply unit is provided inside the grip 1. This power supply unit is a lithium battery and is a rechargeable design. This design is a conventional technical solution and will not be described in detail here.

[0021] In this invention, an appropriate amount of tomato pollen is first placed into the storage box 6. The bracket 5 is then mounted on the handle 1 using bolts. After connecting the end of the connecting pipe 8 to the discharge box 7, the operator holds the handle 1 and aligns the brush head 4 with the tomato stigma to be pollinated. The vibration motor 2 is activated via the control button on the handle 1. The vibration motor 2 begins to vibrate and transmits the vibration to the brush head 4 via the connecting shaft 3. While the handle 1 vibrates, the pollen in the storage box 6 falls into the discharge box 7 through the connecting pipe 8. Subsequently, the pollen falls through the discharge hole 9 into the bristles of the brush head 4. Under the action of vibration, the pollen scatters from the bristles and adheres to the stigma, completing the pollination operation. During the pollination process, the vibration frequency can be adjusted via the control button on the handle 1 to achieve the best pollination effect. After pollination is complete, the switch is turned off.
