[0022] This embodiment provides a sunflower pollen collection device, see Figure 1-Figure 4 As shown, it includes a triangular support plate 1, the three ends of the triangular support plate 1 are respectively connected to a support rod assembly 2, the bottom end of the support rod assembly 2 is used to contact the ground to support the triangular support plate 1, the upper end of the triangular support plate 1 is connected to a support column 3, the upper end of the support column 3 is connected to a clamping plate 4, a first telescopic rod 41 is arranged between the clamping plates 4, one end of the first telescopic rod 41 is connected to the clamping plate 4, the other end of the first telescopic rod 41 is rotatably connected to one end of a connecting rod 42, and the connecting rod 42 The rod body is rotatably connected to the upper end of the clamping plate 4 through a rotating shaft, and the side wall of the connecting rod 42 is connected to the second telescopic rod 43, and the telescopic end of the second telescopic rod 43 is installed with a collecting component 5, and the collecting component 5 includes a powder suction chamber 51, one end of the powder suction chamber 51 is connected to a suction nozzle 52, and the other end of the powder suction chamber 51 is connected to a fan 53, and a filter plate 54 and a filter cloth 55 are respectively arranged in the powder suction chamber 51, and the lower parts of the filter plate 54 and the filter cloth 55 are respectively provided with a first accommodating chamber 541 and a second accommodating chamber 551.

[0023] In the above embodiment, the three end points of the triangular support plate 1 are respectively connected to the support rod assemblies 2, and the bottom ends of the support rod assemblies 2 are used to contact the ground. The three groups of support rod assemblies 2 are arranged around the lower part of the triangular support plate 1, forming a stable support plane at the lower part of the triangular support plate 1, which is beneficial to improve the stability of the collection device. The upper end of the triangular support plate 1 is connected to a support column 3, and the upper end of the support column 3 is connected to a clamping plate 4, one end of a first telescopic rod 41 is fixedly connected between the clamping plates 4, the other end of the first telescopic rod 41 is rotatably connected to one end of a connecting rod 42, and the rod body of the connecting rod 42 is rotatably connected to the upper end of the clamping plate 4 through a rotating shaft, that is, the extension of the first telescopic rod 41 can push the rod body of the connecting rod 42 to rotate around the upper end of the clamping plate 4. Furthermore, a second telescopic rod 43 is connected to the side wall of the connecting rod 42, and a collecting component 5 is installed at the telescopic end of the second telescopic rod 43. The extension and shortening of the second telescopic rod 43 can be used to control the horizontal height of the collecting component 5. The rotation of the rod body of the connecting rod 42 can drive the second telescopic rod 43 to deflect, and then drive the direction of the collecting component 5 to deflect, and the collecting position of the collecting component 5 can be adjusted according to actual conditions, thereby improving the flexibility of adjusting the collecting position of the collecting component 5, which is beneficial to improving the collecting efficiency of the collecting device for sunflower pollen.

[0024] The collecting component 5 comprises a powder suction chamber 51, and a suction nozzle 52 is connected to one end of the powder suction chamber 51, and a fan 53 is connected to the other end of the powder suction chamber 51. The fan 53 can be used to suck out the air in the powder suction chamber 51 to create a negative pressure in the powder suction chamber 51, so that the external air enters the powder suction chamber 51 through the suction nozzle 52, so that an inhalation airflow is generated at the suction nozzle 52, and the suction nozzle 52 is moved close to the flower body. The inhaled airflow sucks the pollen on the flower body from the suction nozzle 52 into the powder suction chamber 51. An inclined filter plate 54 is arranged near the suction nozzle 52 in the powder suction chamber 51. When the pollen is inhaled from the suction nozzle 52, part of the flower body tissue, such as anthers and broken leaves, will be inhaled into the powder suction chamber 51. The filter plate 54 plays a screening role on the inhaled pollen. Small particles of pollen follow the airflow to pass through the filter plate 54, while large particles of anthers and broken leaves are retained by the filter plate 54, which can reduce the impurities mixed in the pollen and is beneficial to improving the purity of the collected pollen.

[0025] Furthermore, a filter cloth 55 is provided on one side of the filter plate 54. The average diameter of sunflower pollen particles is about 30 microns. A filter cloth 55 with a filter aperture less than 30 microns is used. The airflow passes through the filter cloth 55 to retain the pollen particles on the surface of the filter cloth 55. The air in the powder suction chamber 51 is then discharged through the fan 53. After the fan 53 stops running, the large particles attached to the inclined filter plate 54 and the pollen attached to the filter cloth 55 fall into the first accommodating chamber 541 and the second accommodating chamber 551 respectively due to their own gravity for collection. In the process of collecting sunflower pollen, the fan 53 can be intermittently stopped to control the attachments on the filter plate 54 and the pollen on the filter cloth 55 to fall into the first accommodating chamber 541 and the second accommodating chamber 551 respectively. In addition, some pollen may remain in the flower body tissues collected in the first accommodating cavity 541, such as anthers. In later processing, the anthers and other tissues may be dried and then the pollen may be collected again by picking, screening, etc., which is beneficial to improving the pollen collection efficiency.

[0026] In summary, by controlling the extension and shortening of the first telescopic rod 41, the rod body of the connecting rod 42 rotates around the upper end of the clamping plate 4, so that the top of the second telescopic rod 43 drives the collection component 5 to deflect, which can be used to adjust the angle of the collection component 5 to collect pollen, which is beneficial to improving the flexibility of the collection component 5. By controlling the extension and shortening of the second telescopic rod 43, the vertical height of the collection component 5 can be controlled, so that the staff does not need to pull down the sunflower stem to a suitable height for pollen collection, which can avoid breaking and damaging the sunflower. In addition, the collection device removes the air in the powder suction chamber 51 through the fan 53 to cause negative pressure in the powder suction chamber 51, and then sucks the pollen of the sunflower body into the powder suction chamber 51 through the suction nozzle 52, which improves the collection efficiency of pollen compared to manual brushing of pollen, and then screens and filters the pollen through the filter plate 54 and the filter cloth 55 in the powder suction chamber 51, which can improve the collection purity of sunflower pollen, which is beneficial to improving the collection quality of sunflower pollen.

[0027] In one embodiment of the present application, see Figure 1 As shown, the support rod assembly 2 includes a sleeve 21, one end of the sleeve 21 is connected to the end point of the triangular support plate 1, and the other end of the sleeve 21 is plugged into one end of the insert 22. The side walls of the sleeve 21 and the insert 22 are respectively provided with insert holes 211, and the other end of the insert 22 is connected to a support rod 23.

[0028] In the above embodiment, one end of the three sleeves 21 is respectively connected to the three end points of the triangular support plate 1, and the other end of each sleeve 21 is plugged into one end of the insert 22. The other end of the insert 22 is connected to a support rod 23, which is used to contact the ground to play a supporting role. Furthermore, the other end of the sleeve 21 is plugged into one end of the insertion tube 22, and the side walls of the sleeve 21 and the insertion tube 22 are respectively provided with a plug hole 211, and the side wall of the insertion tube 22 is provided with multiple plug holes 211. The insertion tube 22 can be pulled out and pulled out of the sleeve 21, so that the plug hole 211 on the side wall of the sleeve 21 is aligned with a plug hole 211 on the side wall of the insertion tube 22. After the plug holes 211 are aligned, a pin is inserted into the two plug holes 211 for fixing. By controlling the insertion and extraction length of the insertion tube 22 in the sleeve 21, the overall length of the sleeve 21 and the insertion tube 22 can be controlled, and then the supporting area of ​​the support rod assembly 2 can be controlled to adapt to the placement area of ​​the collection device between different sunflowers, which is beneficial to improving the adaptability of the collection device.

[0029] In one embodiment of the present application, refer to Figure 1 As shown, the support rod 23 is a telescopic rod with adjustable length.

[0030] In the above embodiment, the ground in the sunflower planting area may be uneven, which may cause the support rod assembly 2 to tilt when placed, causing the collection device to tip over. By adjusting the support heights of the support rods 23 respectively, the support planes of the support rods 23 can be kept horizontal, thereby helping to improve the stability of the collection device.

[0031] In one embodiment of the present application, see Figure 1 As shown, a universal wheel 231 is installed at the bottom end of the support rod 23.

[0032] In the above embodiment, a universal wheel 231 is installed at the bottom end of the support rod 23. The universal wheel 231 can be used by the staff to push the support rod assembly 2 to walk on the ground, which is beneficial to improving the flexibility of the collection device when moving and improving the pollen collection efficiency. Optionally, the universal wheel 231 has a self-locking brake, and the universal wheel 231 can be locked when moving to a suitable position to improve the stability of the collection device.

[0033] In one embodiment of the present application, see Figure 3 As shown, the first accommodating chamber 541 , the second accommodating chamber 551 and the powder suction chamber 51 are detachably connected.

[0034] In the above embodiment, the first accommodating chamber 541 and the second accommodating chamber 551 are plugged into the bottom plate of the powder suction chamber 51 in a detachable manner. Optionally, the connection between the accommodating chamber and the bottom plate of the powder suction chamber 51 is mutually attracted by magnets, which facilitates the replacement of the accommodating chamber, thereby helping to improve the pollen collection efficiency of the collection device.

[0035] In one embodiment of the present application, see Figure 3 As shown, a first motor 56 is disposed on the top of the powder suction chamber 51 , and a rotating rod 561 is connected to an end point of an output shaft of the first motor 56 .

[0036] In the above embodiment, the first motor 56 is a servo motor, and the first motor 56 drives the rotating rod 561 to rotate. The end of the rotating rod 561 is sleeved with a soft cotton swab. The first motor 56 drives the rotating rod 561 to rotate slowly, and the rotating rod 561 drives the soft cotton swab to slowly move the sunflower body. There is a sticky substance on the surface of sunflower pollen, which is easy to adhere to the anther. Moving the body can break the attachment state of the pollen, making it easier for the pollen to fall off, so that the pollen is easier to be sucked into the powder suction chamber 51 by the suction nozzle 52. In addition, the end of the rotating rod 561 is sleeved with a soft cotton swab, which is not easy to cause damage to the body while moving the body. When the soft cotton swab rotates, it sweeps in front of the suction nozzle 52, and the suction nozzle 52 can absorb part of the pollen attached to the soft cotton swab. The pollen remaining on the soft cotton swab can be scraped off and recycled later, which is beneficial to improve the collection efficiency of pollen.

[0037] In one embodiment of the present application, see Figure 3 and Figure 4 As shown, a second motor 57 is installed on the side wall of the powder suction chamber 51, and the output shaft of the second motor 57 extends into the powder suction chamber 51. The side wall of the output shaft of the second motor 57 is connected to one end of a rotating plate 571, and the other end of the rotating plate 571 extends toward the filter cloth 55 and touches the filter cloth 55.

[0038] In the above embodiment, the sunflower pollen particles are relatively small and easily adhere to the surface of the filter cloth 55. The accumulation of pollen adhering to the surface of the filter cloth 55 easily causes the filter holes of the filter cloth 55 to be blocked, thereby causing the airflow in the powder suction chamber 51 to be poor, affecting the absorption efficiency of the pollen by the collection device. The output shaft of the second motor 57 rotates, driving the rotating plate 571 to rotate. The rotating plate 571 is arranged on the side of the filter cloth 55. When the rotating plate 571 rotates, it touches the filter cloth 55. When touching, the filter cloth 55 is shaken, and the pollen adhered to the filter cloth 55 is shaken off into the second accommodating chamber 551 below the filter cloth 55.

[0039] In one embodiment of the present application, see Figure 3 As shown, a slot 58 is provided in the powder suction chamber 51 , an opening 581 is provided on the side wall of the powder suction chamber 51 , a frame plate 582 is inserted into the opening 581 , a frame hole 583 is provided on the surface of the frame plate 582 , and a filter cloth 55 is connected to the frame hole 583 .

[0040] In the above embodiment, a frame hole 583 is provided on the surface of the frame plate 582, and a filter cloth 55 is fixed in the frame hole 583. The frame plate 582 can be inserted into the slot 58 in the powder suction chamber 51 through the opening 581 on the side wall of the powder suction chamber 51. The size of the frame hole 583 of the frame plate 582 is adapted to the size of the inner cavity cross-section of the powder suction chamber 51. One end of the frame plate 582 extends from the opening 581, which facilitates the frame plate 582 to be pulled out of the slot 58 of the powder suction chamber 51. By replacing the frame plate 582, the filter cloth 55 in the frame hole 583 can be replaced.

[0041] In one embodiment of the present application, see Figure 2 As shown, a storage box 31 is installed on the side of the support column 3.

[0042] In the above embodiment, the storage box 31 is arranged on the side of the bottom end of the support column 3. On the one hand, the pollen collected by the collection device can be placed in the storage box 31 to improve the convenience of pollen transfer. On the other hand, a counterweight block can be placed in the storage box 31 to increase the mass of the bottom end of the support column 3 and lower the center of gravity of the collection device, which is beneficial to improve the stability of the collection device.

[0043] In one embodiment of the present application, see Figure 2 As shown, a cover plate 32 is provided at the upper end of the storage box 31, and the upper end of the cover plate 32 and the outer wall of the storage box 31 are covered with a heat preservation layer.

[0044] In the above embodiment, the flowering period of sunflowers is usually from July to August, which are the core months of summer. The temperature usually reaches the highest throughout the year. The daily average temperature may exceed 30°C, and even above 35°C in some areas. Sunflower pollen usually needs to be stored at low temperatures after collection, because the metabolic activity of pollen slows down in a low temperature environment, which can prolong its activity. The cover 32 and the outer wall of the storage box 31 are coated with an insulation layer that can be used to insulate the storage box 31 and maintain the temperature in the storage box 31. Putting an ice bag in the storage box 31 can reduce the temperature in the storage box 31, which is used to store the collected pollen at low temperatures to prolong the activity of the pollen. Low temperature can inhibit the growth of microorganisms and prevent the pollen from mold or deterioration.
