Description

Technical Field

[0001] This invention belongs to the field of pollen grain capture technology, specifically a pollen capture device. Background Technology

[0002] Pollen is one of the important proxy indicators for paleovegetation and paleoclimate research. As an important carrier of plant reproduction, pollen is widely dispersed and deposited in nature, and can record information about past vegetation and climate. However, it should be noted that the relationship between pollen and vegetation and climate is not a simple linear correspondence, but is affected by a combination of factors such as pollen source, dispersal mode, deposition process and post-preservation. Moreover, in modern process research, pollen needs to be collected by specially designed pollen capture devices. These pollen capture devices usually use efficient collection technology, which can provide rich sample materials for subsequent analysis and research.

[0003] The shortcomings of existing pollen capture devices: Current pollen capture devices typically use a blower to provide the power to extract air and pollen during the capture process. They also include a baffle inside the device to separate impurities other than pollen, facilitating pollen separation and collection. However, due to the vast variety of flower species and sizes in nature, the pollen produced varies greatly. Existing devices often have fixed, non-replaceable baffles, which limits their effectiveness when dealing with pollen of different sizes. During the pollen capture task, the adaptability is clearly insufficient. In addition, because the net is under the strong suction generated by the wind pump for a long time, not only various debris but also some insects may be attracted to the net during the air extraction process. As the working time goes by, these debris and insects continue to accumulate on the surface of the net, causing the net to become blocked. Once the net is blocked, it will not only seriously affect the suction effect of the wind pump, resulting in a significant reduction in pollen extraction efficiency, but also cause the internal pressure of the device to become unbalanced due to poor airflow, further affecting the normal operation of the entire pollen capture device and the pollen capture effect. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a pollen capture device, including a collection tube and a collection head assembled at one end of the collection tube, as well as a quick-release structure assembled inside the collection head and a stamping structure located outside the collection head.

[0005] The quick-release structure includes a baffle and two hydraulic buffer rods symmetrically distributed on the inner wall of the baffle, as well as a return spring sleeved on the outside of the hydraulic buffer rods. The two return springs are fixedly connected to a movable block on the side away from each other.

[0006] The stamping structure includes a support sleeve fixedly installed on the outer wall of the collecting cylinder and a stamping block fixedly installed on the outer wall of the collecting head, as well as a stamping tube connected to the stamping block. The other end of the stamping tube is connected to a pressing balloon. The outer wall of the stamping tube is fixedly connected to the inner wall of the support sleeve. The outer wall of the stamping block has equally spaced punch holes.

[0007] Preferably, it also includes a rotating rod fixedly connected to the end of the collecting cylinder away from the collecting head, a collecting box located behind the rotating rod, and a capturing structure located directly above the rotating rod.

[0008] Preferably, the inner wall of the collecting head has two limiting grooves that are adapted to the movable block, and the outer wall of the baffle has two mounting grooves that correspond to the limiting grooves.

[0009] Preferably, both hydraulic buffer rods and the return spring are located inside the mounting groove.

[0010] Preferably, the rotating rod is rotatably connected to the collection box, and the capture structure includes an assembly box and a pump fixedly installed inside the assembly box, as well as a connecting pipe connected to the output end of the pump, and the input end of the pump is connected to a connecting pipe.

[0011] Preferably, the other end of the connecting pipe extends to the right side of the assembly box and communicates with the collection cylinder, and the other end of the extension pipe extends to the top of the assembly box and communicates with the collection box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a quick-release and stamping structure. When pollen collection from different types and sizes of flowers is required, the operator presses the movable block, causing the return spring to deform and move the movable block downwards. Once the movable block disengages from the limiting groove, the screen can be pulled out directly and replaced with a new one to accommodate pollen particles of different sizes, achieving convenient screen replacement. When impurities accumulate on the screen surface, hindering pollen collection, the operator presses the balloon, causing a rapid compression of the internal space and an increase in air pressure. This increased pressure is transmitted through the stamping tube to the stamping block and ejected at high speed from the punch, creating a powerful airflow impact. This impact acts on the outer wall of the screen, causing the attached impurities to be blown off, restoring the screen's flow and solving the problem of screen blockage. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, this utility model provides a pollen capture device, including a collection cylinder 1 and a collection head 2 assembled at one end of the collection cylinder 1, as well as a quick-release structure 3 assembled inside the collection head 2 and a stamping structure 4 located outside the collection head 2.

[0022] The quick-release structure 3 includes a baffle 31 and two hydraulic buffer rods 32 that are symmetrically distributed on the inner wall of the baffle 31, and a return spring 33 sleeved on the outside of the hydraulic buffer rods 32. The two return springs 33 are fixedly connected to a movable block 34 on the side away from each other.

[0023] The stamping structure 4 includes a support sleeve 41 fixedly installed on the outer wall of the collecting cylinder 1 and a stamping block 42 fixedly installed on the outer wall of the collecting head 2, as well as a stamping tube 43 connected to the stamping block 42. The other end of the stamping tube 43 is connected to a pressing balloon 44. The outer wall of the stamping tube 43 is fixedly connected to the inner wall of the support sleeve 41. The outer wall of the stamping block 42 has equally spaced punch holes.

[0024] The above solution utilizes the quick-release structure 3 and the stamping structure 4. When pollen needs to be captured from different types and sizes of flowers, the operator presses the movable block 34, causing the return spring 33 to deform under pressure, which in turn moves the movable block 34 downwards. Once the movable block 34 is released from the limiting groove, the baffle 31 can be directly pulled out and replaced with a new one to accommodate pollen particles of different sizes, thus achieving convenient replacement of the baffle 31. When pollen collection is affected by impurities accumulating on the surface of the baffle 31, the operator presses the balloon 44, causing the internal space of the balloon to compress rapidly, increasing the air pressure. This increased air pressure is transmitted through the stamping tube 43 to the stamping block 42 and then ejected at high speed from the punch, forming a powerful airflow impact force. This impact force acts on the outer wall of the baffle 31, causing the attached impurities to be blown off, restoring the baffle 31's unobstructed flow and solving the baffle 31 blockage problem.

[0025] like Figures 1 to 5 As shown, it also includes a rotating rod 5 fixedly connected to the end of the collecting cylinder 1 away from the collecting head 2 and a collecting box 6 located behind the rotating rod 5, as well as a capturing structure 7 located directly above the rotating rod 5. The inner wall of the collecting head 2 is provided with two limiting grooves that are adapted to the movable block 34, and the outer wall of the baffle 31 is provided with two mounting grooves that correspond to the limiting grooves.

[0026] The above scheme is adopted: the rotating rod 5 is rotatably connected to the collection box 6, so that the rotating rod 5 can drive the collection cylinder 1 to move when it moves, and the collection head 2 is connected to the collection cylinder 1.

[0027] like Figures 1 to 5 As shown, the two hydraulic buffer rods 32 and the return spring 33 are located inside the mounting groove. The rotating rod 5 is rotatably connected to the collection box 6. The capture structure 7 includes an assembly box 71 and a pump 72 fixedly installed inside the assembly box 71, as well as a connecting pipe 73 connected to the output end of the pump 72. The input end of the pump 72 is connected to a connecting pipe 74.

[0028] The above scheme is adopted: the extraction pump 72 provides power output for pollen capture. When the extraction pump 72 is started, the pollen enters the collection head 2 through the baffle 31, then enters the connecting pipe 73 through the collection cylinder 1, and finally enters the collection box 6 through the connecting pipe 73 and the extension pipe 74, thus achieving the pollen collection effect. The connecting pipe 73 is a telescopic flexible hose.

[0029] like Figures 1 to 5 As shown, the other end of the connecting pipe 73 extends to the right side of the assembly box 71 and is connected to the collection cylinder 1, and the other end of the extension pipe 74 extends to the top of the assembly box 71 and is connected to the collection box 6.

[0030] Working principle and usage process of this utility model:

[0031] First, when pollen capture is required for different types and sizes of flowers, a filter screen 31 adapted to the pollen size needs to be replaced. Pressing the movable block 34 applies pressure to the return spring 33. Under this pressure, the return spring 33 is compressed, causing elastic deformation. As the pressing action continues, the return spring 33 is continuously compressed, accumulating elastic potential energy and causing the movable block 34 to move downwards. When the movable block 34 moves to a certain extent, it completely disengages from the limiting groove, allowing the operator to pull the filter screen 31 directly out of the device without obstruction. A new filter screen 31 suitable for the current pollen capture requirements can then be replaced. However, if impurities are found blocking the surface of the filter screen 31, preventing pollen from being captured... During normal collection, the operator only needs to press the balloon 44. At the moment of pressing the balloon 44, the space inside the balloon is compressed rapidly, causing the air pressure inside the balloon to increase instantly. Due to the pressure difference, this increased air pressure will be quickly transmitted to the stamping block 42 through the connected stamping tube 43. Inside the stamping block 42, the air pressure will quickly accumulate and finally rush out at high speed from the carefully designed perforation. When the high-speed airflow rushes out of the perforation, it will form a strong impact force. This impact force directly acts on the outer wall of the baffle 31. Under the action of the airflow impact force, the impurities attached to the outer wall of the baffle 31 are strongly blown. Due to the impact and disturbance of the airflow, the impurities originally attached to the baffle 31 lose their adhesion and fall off the outer wall of the baffle 31.
