Description

Technical Field

[0001] This invention relates to the field of pollen collection devices, specifically a pollen collection device for tomato seedling cultivation. Background Technology

[0002] Tomatoes are rich in protein, fat, carbohydrates, crude fiber, and various vitamins. In the process of tomato seedling cultivation, pollen collection is a key step in hybridization breeding and artificial pollination. In the process of artificial pollination, operators need to hold a soft brush and gently touch the stigma of the stamen of each tomato flower to collect pollen by adhering it with the brush tip. This manual pollen collection method is not only time-consuming, labor-intensive, and inefficient, but also prone to unstable pollen collection due to differences in operation techniques. It may even cause pollen contamination or variety mixing due to hand shaking or incomplete brush cleaning, making it difficult to meet the dual requirements of pollen collection efficiency and purity for large-scale seedling cultivation.

[0003] Existing pollen collection devices for tomato seedling cultivation use fans to extract pollen from flower stamens and filters the pollen-laden air. However, at the end of pollen collection, due to the lack of a corresponding cleaning mechanism for the filter, some pollen particles accumulate on the filter surface. If not cleaned promptly, the accumulated pollen can clog the mesh channels, increasing airflow resistance and affecting the efficiency of subsequent pollen collection. Therefore, a new pollen collection device for tomato seedling cultivation needs to be designed to solve these problems.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a tomato seedling cultivation pollen collection device to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this application to solve its technical problem is: a tomato seedling cultivation pollen collection device, including a handle and a negative pressure cylinder, the negative pressure cylinder being fixed to the upper end of the handle, and also including a pollen collection cylinder and a flow chamber. The pollen collection cylinder is installed at one end of the negative pressure cylinder, an annular baffle is fixed at one end of the pollen collection cylinder, and a circular baffle is fixed at the other end of the pollen collection cylinder. A bracket is fixed to the lower part of both the annular baffle and the circular baffle, and the bottom of the bracket is fixed inside the pollen collection cylinder. A top plate is fixed to the upper part of both the annular baffle and the circular baffle, and a filter screen is fixed to both the bracket and the top plate. The flow chamber is formed by the annular baffle, the bracket, the top plate, the filter screen, and the pollen collection cylinder, and is suitable for the flow of gas passing through the filter screen. A cleaning frame that can slide along the axial direction of the filter plate is mounted on the support. A plurality of cleaning brushes are fixed on the cleaning frame. The cleaning brushes are adapted to contact the filter plate to clean the attached pollen particles.

[0007] Furthermore, each of the brackets is provided with a limiting groove, and sliders are fixed on both sides of the cleaning frame. The sliders are respectively located in the limiting grooves and can slide along the axial direction of the limiting grooves. A pull rod is fixed on one side of the slider, and one end of the pull rod passes through the limiting groove on one side and extends to the outside of the annular baffle.

[0008] Furthermore, a guide rod is fixed in the limiting groove on the other side, and the slider on the other side is located on the body of the guide rod and can move along the axial direction of the guide rod.

[0009] Furthermore, a pull frame is fixed to the pull rod at a position outside the annular baffle.

[0010] Furthermore, a pollen collection box is connected through the pollen collection tube, and a collection drawer is slidably connected inside the pollen collection box.

[0011] Furthermore, a suction fan is installed inside the negative pressure cylinder, and multiple vent holes are provided at the other end of the negative pressure cylinder. The suction fan is adapted to generate negative pressure to draw in pollen-containing gas, and the vent holes are adapted to discharge filtered clean gas and balance the air pressure inside the negative pressure cylinder.

[0012] Furthermore, a battery is installed inside the grip. Furthermore, an adapter cover is installed at one end of the powder collecting cylinder, and a powder collecting cover is fixed on the adapter cover. The powder collecting cover is adapted to the morphology of tomato stamens.

[0013] By adopting the above technical solution, the problem of reduced pollen collection efficiency in existing tomato seedling cultivation pollen collection devices due to the lack of a cleaning mechanism in the filter screen and the accumulation of pollen clogging the mesh is solved.

[0014] Compared with the prior art, the beneficial effects of the present invention are: in the pollen collection device for tomato seedling cultivation, by setting an axially movable cleaning frame and cleaning brush inside the pollen collection cylinder, the pollen particles accumulated on the surface of the filter screen can be cleaned in time after the pollen collection is completed, reducing the problem of increased airflow resistance caused by mesh blockage, and significantly improving the efficiency of the next pollen collection operation.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-8 This invention provides a technical solution: a tomato seedling cultivation pollen collection device, including a handle 1 and a negative pressure cylinder 2. The negative pressure cylinder 2 is fixed to the upper end of the handle 1 by bolts. A storage battery 4 is installed inside the handle 1. It is a 3.7V rechargeable lithium battery and is electrically connected to the control button on the surface of the handle 1 through wires to provide power support for the device. A suction fan 3 is fixed inside the negative pressure cylinder 2 by a bracket. The suction fan is a DC12V-24W centrifugal fan with a rated speed of 2800r / min. Multiple ventilation holes 5 are evenly distributed at the other end of the negative pressure cylinder 2 to discharge filtered clean gas and balance the air pressure inside the negative pressure cylinder 2.

[0019] One end of the negative pressure cylinder 2 is connected to the powder collection cylinder 6 by a thread. One end of the powder collection cylinder 6 is connected to the adapter cover 21 by a thread. The adapter cover 21 has an integrally formed powder collection cover 22 with an arc-shaped cross section and an opening diameter of 3-5cm, which is suitable for the conical shape of tomato stamens and can fit the flower.

[0020] An annular baffle 7 is welded and fixed to one end of the pollen collection cylinder 6, and a circular baffle 8 is welded and fixed to the other end of the pollen collection cylinder 6. Both are made of aluminum alloy with a thickness of 4mm. A bracket 9 is welded and fixed to the lower part of the annular baffle 7 and the circular baffle 8. The bottom of the bracket 9 is welded and fixed to the inner wall of the pollen collection cylinder 6, and a top plate 10 is welded and fixed to the upper part. A filter screen 11 is fixed to the surface of the bracket 9 and the top plate 10. The mesh diameter is smaller than the average diameter of tomato pollen particles, about 80-100μm, to ensure that pollen particles are effectively intercepted. The annular baffle 7, the bracket 9, the top plate 10, the filter screen 11, and the pollen collection cylinder 6 together form a flow cavity 12 with a circular cross-section and a width of 15mm, which facilitates the rapid passage of filtered gas.

[0021] The inner side of the bracket 9 has two limiting grooves 13, each 8mm wide and 5mm deep. The cleaning frame 14 has a semi-circular frame structure, with sliders 23 welded to both sides. The sliders 23 and the limiting grooves 13 form a clearance fit with a tolerance of H8 / g7, allowing them to slide axially along the limiting grooves 13. A pull rod 16 with a diameter of 4mm is welded to one side of the slider 23. One end of the pull rod passes through a through hole in the annular baffle 7 and extends to the outside. A pull frame 17 is welded to the pull rod 17, which is made of bent metal wire for easy hooking with fingers.

[0022] A guide rod 18 with a diameter of 3mm is welded and fixed inside the right limiting groove 13. The slider 23 on the other side is sleeved on the guide rod 18 through the through hole to ensure the stability of the cleaning frame 14 when it moves. Multiple cleaning brushes 15 are glued to the inside of the cleaning frame 14. The brush bristles are made of nylon and have moderate length and hardness, which can effectively brush off pollen particles on the surface of the filter screen 11 without damaging the mesh.

[0023] A pollen collection box 19 is connected to the bottom of the pollen collection tube 6, and the pollen collection box 19 is welded and fixed to the pollen collection tube 6. A collection drawer 20 is slidably connected inside the collection tube 6. The drawer is made of transparent PET material, which makes it easy to observe the amount of pollen collected. A handle is provided on the outside of the collection drawer 20, which makes it easy to pull out of the collection drawer 20 from the pollen collection box 19.

[0024] Working principle: The operator holds the handle 1 and aligns the pollen collection cover 22 with the tomato stamen. Since the shape of the pollen collection cover 22 is adapted to the structure of the tomato stamen, it can fit most of the stamen, reducing pollen diffusion loss. Then, the operator starts the suction fan 3 by pressing the control button on the handle 1. At this time, the battery 4 in the handle 1 supplies power to the controller, control button and suction fan 3 of the device. The suction fan 3 generates negative pressure, forming an airflow channel from the pollen collection cover 22 to the vent 5. The pollen-containing air is sucked into the pollen collection cylinder 6 through the pollen collection cover 22 and the adapter cover 21. After the pollen-containing gas enters the pollen collection cylinder 6, it first passes through the area enclosed by the support 9, the top plate 10, and the two filter plates 11. At this time, under the continuous suction of the suction fan 3, the airflow will pass through the filter plates 11. The pollen particles are intercepted on the surface of the filter plates 11, while the filtered gas passes through the filter plates 11 and enters the flow chamber 12. Since the mesh diameter of the filter plates 11 is smaller than the diameter of the pollen particles, most of the pollen particles will be intercepted by the filter plates 11. At the same time, the gas in the flow chamber 12 will enter the negative pressure cylinder 2 during the flow process, and then be discharged to the outside of the negative pressure cylinder 2 through the vent 5. When pollen collection is finished, the operator releases the control button, the suction fan 3 stops running, and the air pressure in the negative pressure cylinder 2 and the pollen collection cylinder 6 returns to balance. At this time, most of the pollen has been intercepted on the surface of the filter screen 11 and falls naturally into the pollen collection box 19 at the bottom of the pollen collection cylinder 6 by gravity and is stored in the collection drawer 20 that can be slid out. To ensure collection efficiency, the operator can tap the outside of the pollen collection cylinder 6, which will cause some pollen particles adhering to the surface of the filter screen 11 to fall off. When the filter screen 11 needs to be cleaned, the operator first holds the powder collecting cylinder 6 and rotates it. Since the powder collecting cylinder 6 is threadedly connected to the negative pressure cylinder 2, the powder collecting cylinder 6 can be detached from the negative pressure cylinder 2 after rotating a certain number of times. At the same time, the adapter cover 21 is also threadedly connected to the powder collecting cylinder 6. Similarly, rotating the adapter cover 21 can detach it from the powder collecting cylinder 6. At this time, the operator pulls the pull frame 17, which drives the pull rod 16 and the sliders 23 fixed at both ends of it to move synchronously. One slider 23 slides axially in the limiting groove 13 of the bracket 9, and the other slider 23 moves smoothly along the guide rod 18, ensuring that the cleaning frame 14 remains in close contact with the filter screen 11 during the movement. Multiple cleaning brushes 15 on the cleaning frame 14 move together to brush the pollen particles remaining on the surface of the filter screen 11 into the pollen collection box 19. After cleaning is completed, push the pull frame 17 in the opposite direction to reset the cleaning frame 14 and prepare for the next pollen collection operation. Then, reassemble the pollen collection cylinder 6 in the reverse order of disassembly.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
