Description

Technical Field

[0001] This invention relates to the technical field of pollen collection, specifically a pollen collection device. Background Technology

[0002] Pollen is a high-quality raw material for health foods. It can beautify the skin, slow aging, strengthen the body, boost energy, and quickly eliminate physical fatigue. It can be used both externally and internally, making it an excellent product for strengthening the body and beautifying the skin. Currently, common types of pollen include rapeseed pollen, pine pollen, and pollen from other plants collected and combed by bees.

[0003] Pollen collection is generally divided into manual collection and collection using pollen collectors. The purely manual method mainly involves manually covering the beehive with a paper bag and tapping the bag to allow the pollen to fall into it. This method is time-consuming, labor-intensive, and has low efficiency. Collection using pollen collectors generally involves using a combing device on the beehive to extract pollen grains, but the pollen collection efficiency is too low. Summary of the Invention

[0004] The purpose of this invention is to provide a pollen collection device that solves the problem of low pollen collection efficiency and improves the quality and efficiency of pollen collection.

[0005] To achieve the above objectives, the invention employs the following technical solution:

[0006] A pollen collection device includes a cavity, a filter nozzle, and a collection tube. A sieve barrel is rotatably connected to the cavity, dividing the cavity into an air inlet chamber and an air outlet chamber. The filter nozzle is detachably mounted on the air inlet end of the cavity and communicates with the air inlet chamber. The device also includes a sedimentation chamber communicating with the air inlet chamber. The collection tube is detachably mounted at the bottom of the cavity and communicates with the sedimentation chamber. The filter nozzle is provided with a first filter screen, which has several first filter holes communicating with the air inlet chamber and the outside. The device also includes an output shaft rotatably mounted on the cavity, which is connected to the sieve barrel and has several fan blades. A driven shaft is rotatably connected to the filter nozzle and splinedly connected to the output shaft. A driven wheel is keyed to the end of the driven shaft, and the driven wheel has several scrapers that cooperate with the first filter holes. The sieve barrel has several second filter holes communicating with the air inlet chamber and the air outlet chamber. The air outlet end of the cavity is provided with an air outlet.

[0007] Furthermore, the end of the output shaft is provided with a check wheel, the side of which contacts the filter nozzle and is provided with a spiral groove, and the scraper is inclined and has inclined surfaces on both sides.

[0008] Furthermore, the filter nozzle is provided with several elastic balls, and a sliding rod is provided on one side of each elastic ball. After the sliding rod passes through the first filter screen, a convex plate is provided. A guide block is provided on the first filter screen and slidably connected to the sliding rod. A first spring is provided between the guide block and the convex plate. Several inclined surfaces simultaneously contact several elastic balls, so that they contact one side of the first filter screen. One side of the convex plate contacts the other side of the first filter screen.

[0009] Furthermore, the cavity is provided with an installation hole, the filter is provided with a connecting part that is slidably connected to the installation hole, the connecting part is provided with a plurality of limiting blocks that contact the cavity, the cavity is provided with a plurality of first transverse grooves that are slidably connected to the limiting blocks, and one side of the first transverse groove is provided with a limiting groove that contacts the limiting block.

[0010] Furthermore, the driven shaft has a splined shaft at one end, and the output shaft has a splined sleeve that is slidably connected to the splined shaft at one end.

[0011] Furthermore, the end of the sieve barrel is provided with a conical surface that mates with the connecting part.

[0012] Furthermore, the sieve barrel is eccentrically positioned with respect to the output shaft, and an output motor is mounted on the cavity, with the movable end of the output motor connected to the output shaft.

[0013] Furthermore, the sedimentation chamber is equipped with a partition, which has several inclined holes. The receiving tube is transparent and has scale lines. It also includes an air volume sensor installed at the air outlet.

[0014] Furthermore, the cavity is provided with a convex ring that is slidably connected to the receiving tube, the end of the receiving tube is provided with a limiting plate, a first sealing ring and a second sealing ring are respectively provided between the end face of the receiving tube and the cavity, and between the limiting plate and the convex ring, and a sliding sleeve sleeved on the outside of the receiving tube is slidably connected to the convex ring, and a second spring is provided between the sliding sleeve and the limiting plate.

[0015] Furthermore, a guide post is provided on one side of the sliding sleeve, and a first vertical groove and a second vertical groove are respectively provided on the convex ring. A second horizontal groove is provided between the first vertical groove and the second vertical groove. The first vertical groove extends to the outside, and the guide post slides sequentially in the first vertical groove, the second horizontal groove and the second vertical groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. When pollen needs to be collected, the output shaft is driven to rotate on the cavity, which in turn drives several fan blades on the output shaft to rotate. The fan blades drive the air flow in the cavity and form an airflow. The outside air is drawn into the cavity through the filter at the air inlet end and then discharged to the outside through the air outlet at the air outlet end of the cavity. When the outside air enters the air inlet cavity through the filter at the air inlet end, larger impurities, such as leaves and branches, are isolated outside by the first filter screen. This prevents larger impurities such as leaves and branches from clogging the filter holes of the subsequent pollen filtration, thereby improving the efficiency of subsequent pollen screening. At the same time, it prevents pollen from failing to enter the collection tube in time, which would reduce the amount of pollen collected, thus improving the efficiency of pollen collection.

[0018] 2. The output shaft transmits torque to the driven shaft, causing the driven wheel to rotate together. This causes several scrapers on the driven wheel to come into contact with larger impurities such as leaves that remain on the first filter screen, and to knock them to the outside of the filter nozzle. This prevents them from staying in the first filter hole for a long time, which would affect the efficiency of subsequent pollen passage and further ensure that the pollen enters the collection tube in time, thereby improving the efficiency of pollen collection.

[0019] 3. After pollen enters the air intake chamber, the airflow speed is controlled to carry away lighter impurities (such as lint and fine dust) and allow them to pass through the second filter holes in the sieve barrel into the air outlet chamber. These impurities are then discharged to the outside through the air outlet, further removing impurities from the pollen and improving the quality of the collected pollen. Additionally, an airflow sensor at the air outlet records the amount of air discharged to the outside. Simultaneously, the pollen, being relatively heavy, settles and falls into the sedimentation chamber below the main chamber, then into the collection tube. Finally, by measuring the amount of pollen in the collection tube, the pollen concentration in the corresponding area can be obtained, thus determining whether a large amount of pollen remains, further improving the efficiency of pollen collection.

[0020] 4. When the output shaft rotates clockwise, it will drive the anti-reverse wheel to rotate clockwise and contact the air through the spiral groove, pushing the air in the filter nozzle further towards the air inlet chamber and preventing the airflow from reversing, thus improving the quality and efficiency of pollen collection. In addition, the output shaft transmits torque through the driven shaft, driving the driven wheel to rotate clockwise and contact the air through the inclined surface on the scraper, which can push the airflow further into the filter nozzle, preventing the air after entering the filter nozzle from flowing back, thereby improving the efficiency and quality of pollen collection.

[0021] 5. When the driven wheel rotates on the filter nozzle, it contacts several elastic balls simultaneously via inclined surfaces on several scrapers. The resulting force drives the elastic balls towards the first filter screen, and moves the sliding rod on the first filter screen, guiding the movement of the elastic balls. Simultaneously, the wheel contacts the first spring via a convex plate, compressing the spring until the elastic balls contact the first filter screen. The vibration generated by the collision between the elastic balls and the first filter screen shakes the pollen or impurities adsorbed on the first filter screen off. Then, as the scraper passes the elastic balls, the rebound force generated by the compression of the first spring drives the convex plate to move in the opposite direction until one side contacts the other side of the first filter screen, causing a collision and vibration, further removing the pollen and impurities adsorbed on the first filter screen. This prevents a large amount of pollen or impurities from accumulating on the first filter screen for a long time, affecting the smooth passage of subsequent pollen, thereby improving the efficiency and quality of pollen collection. At the same time, no additional power device is needed to remove impurities from the first filter screen, further reducing the space required for power device installation and the cost of manufacturing.

[0037] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0038] This invention provides a pollen collection device, such as... Figures 1-2As shown, the system includes a cavity 1, a filter nozzle 2, and a receiving tube 3. A sieve barrel 5 is rotatably connected to the cavity 1, dividing the cavity 1 into an air inlet chamber 6 and an air outlet chamber 7. The filter nozzle 2 is detachably mounted at the air inlet end of the cavity 1 and communicates with the air inlet chamber 6. The system also includes a sedimentation chamber 8 communicating with the air inlet chamber 6. The receiving tube 3 is detachably mounted at the bottom of the cavity 1 and communicates with the sedimentation chamber 8. The filter nozzle 2 is equipped with a first filter screen 9, which has several first filter holes 10 communicating with the air inlet chamber 6 and the outside environment. When outside air enters the air inlet chamber 6 through the filter nozzle 2 at the air inlet end, larger impurities, such as leaves and twigs, are isolated by the first filter screen 9, preventing air from entering the cavity. This system prevents larger impurities such as leaves from clogging the filter pores of subsequent pollen filtration, thereby improving the efficiency of subsequent pollen screening. It also prevents pollen from failing to enter the collection tube 3 in time, which would reduce the amount of pollen collected, thus improving the efficiency of pollen collection. The system also includes a rotating output shaft 11 on the cavity 1, which is connected to the sieve barrel 5 and is equipped with several fan blades 12. By driving the output shaft 11 to rotate on the cavity 1, the fan blades 12 on the output shaft 11 will rotate together. The fan blades 12 will push the air flow in the cavity 1 and form an airflow, drawing outside air into the cavity 1 through the filter nozzle 2 at the air inlet end, and then discharging it to the outside through the air outlet 17 at the air outlet end of the cavity 1.

[0039] The filter nozzle 2 is rotatably connected to a driven shaft 13 splinedly connected to the output shaft 11. A driven wheel 14 is keyed to the end of the driven shaft 13. The driven wheel 14 is provided with several scrapers 15 that cooperate with the first filter holes 10. The sieve barrel 5 is provided with several second filter holes 16 connecting the air inlet chamber 6 and the air outlet chamber 7. The air outlet end of the cavity 1 is provided with an air outlet 17. When the output shaft 11 transmits torque to the driven shaft 13, it drives the driven wheel 14 to rotate, causing the scrapers 15 on the driven wheel 14 to contact leaves and other debris remaining on the first filter screen 9. Other larger impurities come into contact with the filter and are knocked to the outside of the filter nozzle 2, preventing them from staying at the first filter hole 10 for a long time and affecting the efficiency of subsequent pollen passage. This further ensures that the pollen enters the collection tube 3 in a timely manner, thereby improving the efficiency of pollen collection. After the pollen enters the air inlet chamber 6, the airflow speed is controlled so that lighter impurities (such as lint and fine dust) are carried away by the airflow and enter the air outlet chamber 7 through the second filter hole 16 provided in the sieve barrel 5. They are then discharged to the outside through the air outlet 17, thereby further removing impurities from the pollen and improving the quality of pollen collection.

[0040] Preferred, such as Figure 2 and Figure 4As shown, the end of the output shaft 11 is provided with a check wheel 18. The side of the check wheel 18 contacts the filter nozzle 2 and is provided with a spiral groove 19. The scraper 15 is inclined and has inclined surfaces 20 on both sides. As shown, when the output shaft 11 rotates clockwise, it will drive the check wheel 18 to rotate clockwise and contact the air through the spiral groove 19, pushing the air in the filter nozzle 2 further towards the air inlet chamber 6 and preventing the airflow from reversing, thereby improving the quality and efficiency of pollen collection. In addition, the output shaft 11 transmits torque through the driven shaft 13, driving the driven wheel 14 to rotate clockwise and contact the air through the inclined surfaces 20 on the scraper 15, which can push the airflow further into the filter nozzle 2, preventing the air after entering the filter nozzle 2 from flowing back, thereby improving the efficiency and quality of pollen collection.

[0041] Preferred, such as Figure 3 , Figure 4 and Figure 5 As shown, the filter nozzle 2 is provided with several elastic balls 21. A sliding rod 22 is provided on one side of each elastic ball 21. After passing through the first filter screen 9, the sliding rod 22 is provided with a protruding plate 23. A guide block 24 is provided on the first filter screen 9, slidably connected to the sliding rod 22. A first spring 25 is provided between the guide block 24 and the protruding plate 23. Several inclined surfaces 20 simultaneously contact several elastic balls 21, causing them to contact one side of the first filter screen 9. One side of the protruding plate 23 contacts the other side of the first filter screen 9. When the driven wheel 14 rotates on the filter nozzle 2, the inclined surfaces 20, which are respectively provided on several scrapers 15, simultaneously contact several elastic balls 21, generating a component force that drives the elastic balls 21 to move towards the first filter screen 9, and drives the sliding rod 22 to move on the first filter screen 9, thus guiding the movement of the elastic balls 21. Simultaneously, the protruding plate 25... The scraper 3 contacts the first spring 25 and compresses the first spring 25 until the elastic ball 21 contacts the first filter screen 9. The vibration generated by the collision between the elastic ball 21 and the first filter screen 9 shakes the pollen or impurities adsorbed on the first filter screen 9 off the first filter screen 9. Then, when the scraper 15 passes the elastic ball 21, the rebound force generated by the compression of the first spring 25 will drive the convex plate 23 to move in the opposite direction until one side of it contacts the other side of the first filter screen 9 and a collision occurs to generate vibration, further removing the pollen and impurities adsorbed on the first filter screen 9. This prevents a large amount of pollen or impurities from accumulating on the first filter screen 9 for a long time, which would affect the smooth passage of subsequent pollen. This improves the efficiency and quality of pollen collection. At the same time, no additional power device is needed to drive the removal of impurities from the first filter screen 9, further reducing the space required for power device installation and the cost of manufacturing.

[0042] Preferred, such as Figure 4 and Figure 6As shown, the cavity 1 is provided with a mounting hole 26, and the filter 2 is provided with a connecting part 27 that is slidably connected to the mounting hole 26. The connecting part 27 is provided with a plurality of limiting blocks 28 that contact the cavity 1. The cavity 1 is provided with a plurality of first transverse grooves 29 that are slidably connected to the limiting blocks 28. One side of the first transverse groove 29 is provided with a limiting groove 30 that contacts the limiting block 28. When the filter 2 needs to be installed, the connecting part 27 of the filter 2 is slid into the mounting hole 26 provided on the cavity 1, and by rotating the filter 2, the plurality of limiting blocks 28 provided on it enter the corresponding first transverse grooves 29 until the limiting blocks 28 contact the cavity 1. By rotating the filter 2 clockwise, the limiting blocks 28 enter the corresponding limiting grooves 30 until their sides contact the cavity 1, thereby restricting the filter 2 in the cavity 1. The filter tip 2 is initially fixed to the cavity 1 by moving axially and rotating clockwise. When pollen needs to be collected from the corresponding area, the component force generated by the scraper 15 on the driven wheel 14 after contacting the elastic ball 21 will continuously apply a clockwise pushing force to the filter tip 2. This prevents the filter tip 2 from falling off the cavity 1 under the action of external force during the pollen collection process, which would affect the normal collection of pollen. This ensures the stability of the overall structure during the pollen collection process and improves the quality and efficiency of pollen collection. At the same time, when the filter tip 2 needs to be replaced, it is only necessary to rotate the filter tip 2 counterclockwise to pull it out of the cavity 1, thereby simplifying the steps of installing and removing the filter tip 2 and improving the efficiency of replacing the filter tip 2. In addition, there is no need to set up an additional power device to fix the filter tip 2 on the cavity 1, which further reduces the space required for power device installation and the cost of manufacturing.

[0043] Preferred, such as Figure 2 As shown, the end of the sieve barrel 5 is provided with a conical surface 33 that cooperates with the connecting part 27. The airflow entering the air inlet chamber 6 from the filter nozzle 2 first contacts the conical surface 33 provided at the end of the sieve barrel 5 and disperses the pollen and impurities, preventing impurities from being continuously adsorbed on the pollen. This facilitates the subsequent separation of impurities and pollen by airflow, further improving the quality of pollen collection.

[0044] Preferred, such as Figure 2 As shown, the sieve barrel 5 is eccentrically positioned with respect to the output shaft 11, causing the output shaft 11 to drive the sieve barrel 5 to rotate eccentrically. This causes impurities and pollen adsorbed on the sieve barrel 5 to fall off, allowing the pollen to settle smoothly and the impurities to pass through the second filter hole 16 for removal, further improving the quality of the collected pollen. In addition, no additional power device is needed to remove the impurities and pollen adsorbed on the sieve barrel 5, further reducing the space required for power device installation and the cost of manufacturing. The cavity 1 is equipped with an output motor 34, the movable end of which is connected to the output shaft 11 to provide power for the rotation of the output shaft 11.

[0045] Preferred, such as Figure 4As shown, the driven shaft 13 is provided with a spline shaft 31 at its end, and the output shaft 11 is provided with a spline sleeve 32 that is slidably connected to the spline shaft 31 at its end. The spline sleeve 32 is slidably connected to the spline shaft 31 to ensure that the output shaft 11 transmits torque to the driven shaft 13, thereby driving the driven wheel 14 to rotate and removing impurities that remain on the filter nozzle 2, preventing them from remaining at the first filter hole 10 for a long time, thus improving the efficiency of pollen collection. At the same time, it is convenient to disassemble the filter nozzle 2 and replace it with other specifications of filter nozzle 2 to adapt to different flower species and leaf sizes in different regions, thereby improving the efficiency and quality of pollen collection for different flower species.

[0046] Preferred, such as Figure 7 As shown, the sedimentation chamber 8 is equipped with a partition 35, which has several inclined holes 36. After pollen enters the sedimentation chamber 8, it gradually enters the collection tube 3 through the inclined holes 36. At the same time, because the inclined holes 36 are inclined, it prevents the airflow from carrying the settled pollen back into the air inlet chamber 6, further ensuring that the pollen enters the collection tube 3 in a timely manner, thereby improving the efficiency of pollen collection. The collection tube 3 is transparent and has scale lines 37. It also includes an air volume sensor 4 set at the air outlet 17. The air volume sensor 4 set at the air outlet 17 records the amount of air discharged to the outside. At the same time, the pollen, due to its relative weight, settles and falls into the sedimentation chamber 8 below the chamber 1 and enters the collection tube 3. By observing the changes in the amount of pollen in the collection tube 3 through the scale lines 37, the concentration of pollen in the corresponding area can be obtained, thereby determining whether there is still a large amount of pollen, further improving the efficiency of pollen collection.

[0047] Preferred, such as Figure 7 and Figure 8 As shown, the cavity 1 is provided with a convex ring 38 that is slidably connected to the receiving tube 3. The end of the receiving tube 3 is provided with a limiting plate 39. A first sealing ring 40 and a second sealing ring 41 are respectively provided between the end face of the receiving tube 3 and the cavity 1, and between the limiting plate 39 and the convex ring 38. A sliding sleeve 42 is slidably connected to the convex ring 38 and sleeved on the outside of the receiving tube 3. A second spring 43 is provided between the sliding sleeve 42 and the limiting plate 39. The sliding sleeve 42 is pre-sleeved on the outside of the receiving tube 3, and then the receiving tube 3 is inserted into the convex ring 38 until the first sealing ring 40 and the second sealing ring 41 are connected. The sleeve 42 contacts the cavity 1 and the convex ring 38 respectively. Finally, the sleeve 42 is moved so that it slides on the convex ring 38 and compresses the second spring 43 provided between the limiting plate 39 and the sleeve 42. The rebound force generated by the compression of the second spring 43 restricts the collection tube 3 from sliding down, thereby ensuring the stability of the connection between the collection tube 3 and the cavity 1 during the pollen collection process. At the same time, the rebound force generated by the compression of the second spring 43 will further compress the first sealing ring 40 and the second sealing ring 41 to prevent pollen from leaking out from the gap between the collection tube 3 and the cavity 1, thereby improving the efficiency of pollen collection.

[0048] Preferred, such as Figure 8 and Figure 9 As shown, a guide post 44 is provided on one side of the sliding sleeve 42. A first vertical groove 45 and a second vertical groove 46 are respectively provided on the convex ring 38. A second horizontal groove 47 is provided between the first vertical groove 45 and the second vertical groove 46. The first vertical groove 45 extends to the outside. The guide post 44 slides sequentially in the first vertical groove 45, the second horizontal groove 47, and the second vertical groove 46. When it is necessary to install the storage tube 3, first slide the storage tube 3 into the convex ring 38, and then slide the sliding sleeve 42 upward so that the guide post 44 on the sliding sleeve 42 slides into the first vertical groove 45 until the guide post 44 moves to the connection between the first vertical groove 45 and the second horizontal groove 47. Then rotate the sliding sleeve 42 so that it slides into the second horizontal groove 47. The guide post 44 slides within the second horizontal groove 47 until it reaches the connection between the second horizontal groove 47 and the second vertical groove 46. Finally, the external force is removed, and under the action of the rebound force of the second spring 43, the sliding sleeve 42 moves downward, causing the guide post 44 to enter the second vertical groove 46. The guide post 44 contacts the second vertical groove 46, restricting the sliding sleeve 42 from rotating on the convex ring 38 and moving downward. At the same time, the rebound force generated by the compression of the second spring 43 restricts the sliding sleeve 42 from moving upward, thereby restricting the sliding sleeve 42 from moving and rotating on the convex ring 38. This fixes the collection tube 3 on the cavity 1, simplifies the steps of installing and removing the collection tube 3, and further improves the efficiency of pollen collection.

[0049] Example 1

[0050] This invention provides a pollen collection device, such as... Figure 1 and Figure 2 As shown, when pollen needs to be collected, the output shaft 11 is driven to rotate on the cavity 1, which in turn drives several fan blades 12 on the output shaft 11 to rotate together. The fan blades 12 push the air in the cavity 1 to flow and form an airflow. The outside air is drawn into the cavity 1 through the filter 2 at the air inlet end, and then discharged to the outside through the air outlet 17 at the air outlet end of the cavity 1. When the outside air enters the air inlet cavity 6 through the filter 2 at the air inlet end, larger impurities, such as leaves and branches, are isolated outside by the first filter screen 9. This prevents larger impurities such as leaves from clogging the filter holes of the subsequent pollen filtration, thereby improving the efficiency of subsequent pollen screening. At the same time, it prevents the pollen from failing to enter the collection tube 3 in time, which would reduce the amount of pollen collected and affect the efficiency of pollen collection.

[0051] At the same time, the output shaft 11 transmits torque to the driven shaft 13, which drives the driven wheel 14 to rotate together. This causes the scrapers 15 on the driven wheel 14 to come into contact with leaves and other larger impurities that remain on the first filter screen 9, and to knock them to the outside of the filter nozzle 2. This prevents them from staying in the first filter hole 10 for a long time, which would affect the efficiency of subsequent pollen passage and further ensure that the pollen enters the collection tube 3 in time, thereby improving the efficiency of pollen collection.

[0052] After pollen enters the air intake chamber 6, the airflow speed is controlled so that lighter impurities (such as lint and fine dust) are carried away by the airflow and enter the air outlet chamber 7 through the second filter hole 16 provided in the sieve barrel 5. They are then discharged to the outside through the air outlet 17, thereby further removing impurities from the pollen and improving the quality of the collected pollen.

[0053] Example 2

[0054] Based on Example 1, such as Figures 2-5 As shown, when the output shaft 11 rotates clockwise, it will drive the anti-reverse wheel 18 to rotate clockwise and contact the air through the spiral groove 19, pushing the air in the filter 2 further towards the air inlet chamber 6 and preventing the airflow from reversing, thereby improving the quality and efficiency of pollen collection. In addition, the output shaft 11 transmits torque through the driven shaft 13, driving the driven wheel 14 to rotate clockwise and contact the air through the inclined surface 20 provided on the scraper 15, which can push the airflow further into the filter 2, preventing the air after entering the filter 2 from flowing back, thereby improving the efficiency and quality of pollen collection.

[0055] When the driven wheel 14 rotates on the filter nozzle 2, it contacts several elastic balls 21 simultaneously via the inclined surfaces 20 respectively set on several scrapers 15. The resulting force drives the elastic balls 21 to move towards the first filter screen 9, and drives the slide rod 22 to move on the first filter screen 9, guiding the movement of the elastic balls 21. At the same time, it contacts the first spring 25 through the convex plate 23 and compresses the first spring 25 until the elastic balls 21 contact the first filter screen 9. The vibration generated by the collision between the elastic balls 21 and the first filter screen 9 shakes the pollen or impurities adsorbed on the first filter screen 9 away from the first filter screen 9. Next, when the scraper 15 passes the elastic ball 21, the rebound force generated by the compression of the first spring 25 will drive the convex plate 23 to move in the opposite direction until one side of it contacts the other side of the first filter screen 9 and a collision occurs, generating vibration. This further removes the pollen and impurities adsorbed on the first filter screen 9, thereby preventing a large amount of pollen or impurities from accumulating on the first filter screen 9 for a long time, which would affect the smooth passage of subsequent pollen. This improves the efficiency and quality of pollen collection. At the same time, no additional power device is needed to drive the removal of impurities from the first filter screen 9, further reducing the space required for power device installation and the cost of manufacturing.

[0056] Example 3

[0057] Based on Example 2, such as Figure 4 and Figure 6 As shown, since the driven shaft 13 is provided with a splined shaft 31 at its end and the output shaft 11 is provided with a splined sleeve 32 that is slidably connected to the splined shaft 31 at its end, it ensures that the output shaft 11 transmits torque to the driven shaft 13, driving the driven wheel 14 to rotate, removing impurities that remain on the filter nozzle 2, preventing them from remaining at the first filter hole 10 for a long time, thereby improving the efficiency of pollen collection; at the same time, it is convenient to disassemble the filter nozzle 2 and replace it with other specifications of filter nozzle 2 to adapt to different flower species and leaf sizes in different regions, thereby improving the efficiency and quality of pollen collection for different flower species;

[0058] When the filter tip 2 needs to be installed, slide the connecting part 27 of the filter tip 2 into the mounting hole 26 provided on the cavity 1, and rotate the filter tip 2 so that the several limiting blocks 28 provided on it enter the corresponding first transverse groove 29 until the limiting blocks 28 contact the cavity 1. Then, rotate the filter tip 2 clockwise so that the limiting blocks 28 enter the corresponding limiting groove 30 until their side contacts the cavity 1, thereby restricting the filter tip 2 from moving axially and rotating clockwise on the cavity 1, and initially fixing the filter tip 2 on the cavity 1.

[0059] When pollen needs to be collected, the component force generated after the scraper 15 on the driven wheel 14 comes into contact with the elastic ball 21 will continuously apply a clockwise pushing force to the filter 2, preventing the filter 2 from falling off the cavity 1 under the action of external force during the pollen collection process, which would affect the normal collection of pollen, thereby ensuring the stability of the overall structure during the pollen collection process and improving the quality and efficiency of pollen collection.

[0060] When the filter tip 2 needs to be replaced, simply rotate the filter tip 2 counterclockwise to pull it out of the cavity 1, thereby simplifying the steps of installing and removing the filter tip 2 and improving the efficiency of replacing the filter tip 2. In addition, there is no need to set up an additional power device to fix the filter tip 2 on the cavity 1, which further reduces the space required for power device installation and the cost of manufacturing.

[0061] Example 4

[0062] Based on Example 1, such as Figure 3 and Figure 7As shown, when the airflow enters the air inlet chamber 6 through the filter nozzle 2, it first contacts the conical surface 33 at the end of the sieve barrel 5, breaking up the pollen and impurities in the airflow and preventing impurities from being continuously adsorbed on the pollen. This facilitates the subsequent separation of impurities and pollen through the airflow, further improving the quality of the collected pollen. At the same time, the output shaft 11 drives the sieve barrel 5 to rotate eccentrically, further dislodging the impurities and pollen adsorbed on the sieve barrel 5, allowing the pollen to settle smoothly and the impurities to pass smoothly through the second filter hole 16, further improving the quality of the collected pollen. In addition, no additional power device is needed to remove the impurities and pollen adsorbed on the sieve barrel 5, further reducing the space required for power device installation and the cost of manufacturing. The cavity 1 is equipped with an output motor 34, and the movable end of the output motor 34 is connected to the output shaft 11 to provide power for the rotation of the output shaft 11.

[0063] After pollen enters the sedimentation chamber 8, it gradually enters the collection tube 3 through the inclined hole 36. At the same time, because the inclined hole 36 is set at an angle, it prevents the airflow from carrying the sedimented pollen back into the air inlet chamber 6, further ensuring that the pollen enters the collection tube 3 in a timely manner, thereby improving the efficiency of pollen collection.

[0064] In addition, by using the air volume sensor 4 installed at the air outlet 17, the amount of air discharged to the outside is recorded. At the same time, by using the scale line 37 on the collection tube 3, the change in the amount of pollen in the collection tube 3 can be known, and the concentration of pollen in the corresponding area can be obtained, thereby determining whether there is still a large amount of pollen, and further improving the efficiency of pollen collection.

[0065] Example 5

[0066] Based on Example 1, such as Figures 7-9 As shown, the sliding sleeve 42 is pre-fitted onto the outside of the receiving tube 3. Then, the receiving tube 3 is inserted into the protruding ring 38 until the first sealing ring 40 and the second sealing ring 41 contact the cavity 1 and the protruding ring 38 respectively. Finally, the sliding sleeve 42 is moved upwards, causing the guide post 44 on the sliding sleeve 42 to slide into the first vertical groove 45 until the guide post 44 moves to the connection point between the first vertical groove 45 and the second horizontal groove 47. Then, the sliding sleeve 42 is rotated, causing it to slide within the second horizontal groove 47 until the guide post 44 moves to the connection point between the second horizontal groove 47 and the second vertical groove 46. Finally, the outer sleeve is removed. The force, under the action of the second spring 43's rebound force, drives the sliding sleeve 42 to move downward, so that the guide post 44 enters the second vertical groove 46. The guide post 44 contacts the second vertical groove 46, restricting the sliding sleeve 42 from rotating on the convex ring 38 and moving downward. At the same time, the rebound force generated by the compression of the second spring 43 restricts the sliding sleeve 42 from moving upward, thereby restricting the sliding sleeve 42 from moving and rotating on the convex ring 38, thus fixing the collection tube 3 on the cavity 1. This simplifies the steps of installing and removing the collection tube 3 and further improves the efficiency of pollen collection.

[0067] In addition, when the sliding sleeve 42 slides upward on the convex ring 38, it compresses the second spring 43 provided between the limiting plate 39 and the sliding sleeve 42. The rebound force generated after the second spring 43 is compressed restricts the collection tube 3 from sliding downward, thereby ensuring the stability of the connection between the collection tube 3 and the cavity 1 during the pollen collection process. At the same time, the rebound force generated after the second spring 43 is compressed will further compress the first sealing ring 40 and the second sealing ring 41, preventing pollen from leaking out from the gap between the collection tube 3 and the cavity 1, thereby improving the efficiency of pollen collection.
