Description

Technical Field

[0001] This utility model relates to the field of horticultural plant breeding technology, and in particular to a pollen collection device. Background Technology

[0002] Currently, large-scale pollen collection is mainly carried out using pollen collection devices equipped with fans.

[0003] Chinese patent CN 222128761 U discloses a pollen collector, including a pollen suction head, a front chamber, and a rear chamber. Pollen is collected in the front of the dust collection chamber of the pollen suction head and the front chamber. After the pollen collection is completed, the connection between the dust collection chamber and the main body needs to be unscrewed before the pollen can be poured into a petri dish. The pollen remaining on the inner wall of the dust collection chamber is then swept out with a brush. This device requires complete disassembly to remove the collected pollen, and the operation of sweeping out the remaining pollen with a brush is complicated. Furthermore, after unscrewing the connection between the dust collection chamber and the main body, although the pollen barrier layer is in the groove, it is shallow and has a near-planar structure. Pouring the pollen into the petri dish generally needs to be done in a windless, sealed environment, such as a laboratory, to prevent the pollen from being blown away by the wind, thus limiting the operation to specific locations.

[0004] Chinese patent CN 219019588 U discloses a marigold pollen collector, which includes a pollen collection tube and a collection box. The collection box is equipped with a filter screen, and the collection chamber is located behind the filter screen. Although the filter screen is equipped with a scraping component to facilitate the pollen falling into the collection box, the entire pollen collector still needs to be disassembled when the collected pollen is taken out from the collection box. The operation is also limited by the location.

[0022] The purpose of this invention is to provide a pollen collection device to solve the problems existing in the prior art.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The pollen collection device in this embodiment, such as Figures 1-7 As shown, powder suction head 1; Connecting tube 2, which has a first port 24, a second port 25 and a third port 26, the first port 24 being used to connect and communicate with the powder suction head 1; The exhaust device 5 is connected to and communicates with the second pipe 25, and is used to provide power for the pollen suction head 1 to suction pollen; and The collecting filter element 3 has a collecting chamber inside. The first end of the collecting filter element 3 has an air inlet that communicates with the collecting chamber. The second end of the collecting filter element 3 is fixedly connected to an end cap 6. The first end can extend into the connecting pipe body 2 from the third pipe port 26, and the outer periphery of the first end of the collecting filter element 3 is in circumferential contact with the inner wall of the connecting pipe body 2. The collecting filter element 3 is inclined and the second end gradually tilts towards the exhaust device 5. The end cap 6 is detachably connected to the connecting pipe body 2 and can close the third pipe port 26. Air can carry pollen into the collecting filter element 3 from the air inlet. After the collecting filter element 3 blocks and collects the pollen, the air flows from the side wall of the collecting filter element 3 to the second pipe port 25.

[0025] In some embodiments, the powder suction head 1 includes a bent pipe with a bend at the front end. The pollen suction port at the front end of the powder suction head 1 is provided with a barrier filter 11 with a pore size of 60-80 mesh to block petals and impurities. The bent structure makes it easy to align with the powder suction point.

[0026] In some embodiments, a handle pipe 4 for holding the entire device by hand is also provided between the connecting pipe 2 and the exhaust device 5. The first end and the second end of the handle pipe 4 are respectively connected to the second port 25 of the connecting pipe 2 and the air inlet of the exhaust device 5. The exhaust device 5 has a diagonal strap. When sucking powder, the exhaust device 5 is first slung diagonally over the shoulder, and then the handle pipe 4 is held in hand to start the exhaust device 5, generating suction force inside the entire device pipe. For easy disassembly and assembly, the powder suction head 1, the connecting pipe 2, the handle pipe 4, and the exhaust device 5 can all preferably be connected by threaded connections. The outer diameter of the handle pipe 4 can also be set to be the same as the inner diameter of the exhaust port of the exhaust device 5, allowing for direct and quick insertion and connection.

[0027] In some embodiments, an integrally formed bypass pipe 21 is also provided at the third port 26 of the connecting pipe 2. The end of the bypass pipe 21 away from the connecting pipe 2 is inclined toward the exhaust device 5. The connecting pipe 2 and the cavity of the bypass pipe 21 are connected. A limiting ring 23 is also provided inside the pipe of the connecting pipe 2. The limiting ring 23 is located between the first port 24 and the third port 26. The collecting filter element 3 is supported by the bypass pipe 21 and its first end abuts against the limiting ring 23. The end cap 6 is detachably connected to the bypass pipe 21 and can close the bypass pipe 21. The limiting ring 23 is provided with a deflection hole 22 that communicates with the air inlet of the collecting filter element 3. The deflection hole 22 is coaxial with the bypass pipe 21. The diameter of the deflection hole 22 is smaller than the diameter of the collecting filter element 3, so that the air carrying pollen must pass through the collecting filter element 3 and then flow to the rear section of the connecting pipe 2.

[0028] In some embodiments, the bypass tube is made of transparent plastic and is integrally formed with the connecting tube, meaning the connecting tube is also made of transparent plastic. The bypass tube is made of transparent plastic, allowing direct observation of the amount of pollen collected.

[0029] In some embodiments, the collecting filter element 3 includes a cylindrical support frame 31 and a circular pollen-blocking cloth 32. The circular pollen-blocking cloth 32 is built inside the cylindrical support frame 31. The center of the circular pollen-blocking cloth 32 is provided with a circular fold with a diameter equal to the diameter of the air inlet of the collecting filter element 3. Several radial folds are pre-made around the circular fold. The circular pollen-blocking cloth 32 is folded along the circular fold and the radial folds are folded in sequence to make the circular pollen-blocking cloth 32 into a cylindrical shape. The circular fold is the bottom, and the top is the circular inlet opposite to the air inlet of the collecting filter element 3. After the circular pollen-blocking cloth 32 is folded, it is placed into the cylindrical support frame 31, so that it is evenly built into the cylindrical support frame 31. The outer wall of the cylindrical support frame 31 is a hollow structure that allows the circular pollen-blocking cloth 32 to communicate with the outside.

[0030] In some embodiments, the internal volume of the filter element for collecting pollen is preferably 10 ml, which can hold 2 grams of pollen.

[0031] In some embodiments, the end cap 6 is integrally formed with the cylindrical support frame 31. The end cap 6 includes a connecting thread 61 and a disassembly knob 62. The connecting thread 61 is threadedly connected to the bypass tube 21. The disassembly knob 62 is sealed outside the end of the bypass tube 21 away from the connecting tube 2. The disassembly knob 62 has anti-slip vertical grooves. After the collecting filter element 3 intercepts and collects pollen, the collecting filter element 3 can be disassembled simply by turning the disassembly knob 62 to separate the cylindrical support frame 31 from the bypass tube 21.

[0032] In some embodiments, the pore size of the circular pollen-blocking cloth 32 is smaller than the diameter of the pollen to be collected. When the pollen is marigold pollen, the pore size of the circular pollen-blocking cloth 32 is less than 20 micrometers.

[0033] It should be noted that the pollen collection device in this embodiment is not limited to collecting marigold pollen. By replacing the circular pollen-blocking cloth 32 with different pore sizes, it can also be used to collect pollen from other varieties of fresh flowers.

[0034] like Figure 8 As shown, the airflow mixed with pollen first passes through the pollen suction head 1. When it reaches the connecting tube 2 in the middle section, the airflow changes direction and enters the pollen collection filter 3 in the bypass tube 21. The pollen is blocked and retained in the collection filter 3. The airflow after filtering out the pollen continues to flow through the collection filter 3 to the rear section of the connecting tube 2, and then is discharged through the handle tube 4. During the pause between pollen suction cycles, the pollen will settle at the bottom of the collection filter 3 due to its own gravity, which will not affect the smooth flow of airflow when the machine is restarted.

[0035] Pollen is collected in the collection filter 3. At the planting base, the collection filter 3 can be easily removed from the bypass tube 21 by turning the disassembly knob 62 and placed upright in a low-temperature temporary storage box to prevent pollen from remaining in the pollen absorption device for a long time and affecting pollen viability. After replacing the filter with a new spare filter, the device can be quickly connected to the operation, with high pollen absorption efficiency.

[0036] When pollen is needed, the pollen-blocking cloth can be directly pulled out from the cylindrical support frame 31, and the pollen can be shaken into the container for use. The use of pollen is convenient and efficient.

[0037] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
