Description

Technical Field

[0001] This invention relates to the field of crop harvesting technology, and more specifically, to a pine pollen harvesting device. Background Technology

[0002] Pine pollen is a small, yellow or orange powdery substance rich in amino acids, vitamins, minerals, and antioxidants, thus possessing certain medicinal value. Furthermore, because pine pollen has a short flowering period and the pollen on the surface of the flower spike is easily dispersed by wind, it needs to be harvested promptly after maturity.

[0003] Current methods for harvesting pine pollen often involve shaking the branches to accelerate pollen release. However, during shaking, some pollen spikes on the branches may fall directly to the ground due to significant inertial forces, resulting in wasted pollen. Furthermore, shaking cannot effectively guarantee pollen harvesting efficiency, and pollen from higher branches is often difficult to collect. Additionally, pollen temporarily collected in the cavity may disrupt normal airflow as its volume increases and it disperses within the cavity.

[0004] Based on this, the present invention discloses a pine pollen harvesting device. Summary of the Invention

[0005] To address the problems mentioned in the background art, such as some pollen spikes falling due to large inertial forces during pine pollen harvesting, the inability to guarantee pollen harvesting efficiency, the difficulty in reaching pollen at higher positions, and the potential interference of normal airflow with temporarily harvested pollen after being subjected to airflow, this invention provides a pine pollen harvesting device, which includes a connecting chamber. Fans are installed on both sides of the front end of the connecting chamber, and hollow columns are fixedly connected to both sides of the top end of the connecting chamber. Multiple air inlets are opened inside the hollow columns on both sides.

[0006] In this technical solution, to improve the efficiency of pine pollen detachment from the flower spike and avoid requiring excessively large fans to provide wind power, it is necessary to actively knock off the pollen.

[0007] As a further improvement to this technical solution, a rotating mechanism is provided on the outer side of the hollow columns on both sides, a lifting mechanism is provided at the middle of the top of the connecting compartment, a horizontal plate is provided at the top of the lifting mechanism, and the two ends of the horizontal plate are respectively located on the side close to the rotating mechanism on both sides.

[0008] Both sides of the connecting chamber are provided with processing cylinders. The front ends of the processing cylinders on both sides are connected to the fan through perforated plates. The rear ends of the connecting chamber are provided with exhaust holes on both sides. The processing cylinders on both sides are provided with collection mechanisms. Both processing cylinders on both sides are connected to the hollow column.

[0009] As a further improvement to this technical solution, the rotating mechanism includes connecting rings. The inner sides of both connecting rings are slidably connected to the outer sides of the hollow column. Air chambers are fixedly connected to the front ends of both connecting rings. Impellers are rotatably connected inside both air chambers. Rotating rods are fixedly connected to the middle of both impellers. The front ends of both rotating rods pass through the air chambers and are fixedly connected to brushes. The outer rear ends of both brushes are rotatably connected to the front ends of the air chambers. Both air chambers are connected to the fan through air pipes.

[0010] Based on this, in order to limit the extreme positions of the connecting ring, it is necessary to block the connecting ring.

[0011] As a further improvement to this technical solution, the bottom ends of the connecting rings on both sides are abutted by blocks on the front and back sides, and the blocks on the front and back sides that are close to each other are fixedly connected to the front and back sides of the hollow columns on both sides.

[0012] In another technical solution, the rotating mechanism needs to be moved in order to harvest pollen from higher elevations.

[0013] As a further improvement to this technical solution, the lifting mechanism includes a hollow cylinder. The bottom end of the hollow cylinder is fixedly connected to the middle of the top of the connecting chamber. The air chambers on both sides are connected to the hollow cylinder through air pipes. A push rod is slidably connected inside the hollow cylinder. The top end of the push rod passes through the hollow cylinder and is fixedly connected to the bottom of the horizontal plate. The two ends of the horizontal plate are respectively fixedly connected to the side of the connecting rings on both sides that are close to each other. A square chamber is fixedly connected to the middle of the connecting chamber. A sliding plate is slidably connected inside the square chamber. Trapezoidal blocks are slidably connected to both sides of the square chamber. Trapezoidal blocks are slidably connected to the side of the trapezoidal blocks on both sides that are far apart from each other. An air outlet is opened at the lower rear end of the square chamber.

[0014] Based on this, in order to allow air to re-accumulate after the air is expelled from the square chamber and cause the rotating mechanism to move upward again, the slide plate needs to actively return.

[0015] As a further improvement to this technical solution, a magnet is fixedly connected to the middle of the bottom of the connecting compartment, and a magnet is fixedly connected to the bottom of the sliding plate, with the magnet one facing the magnet two.

[0016] Secondly, in order to guide the movement of trapezoidal block two and limit its range of motion,

[0017] As a further improvement to this technical solution, the front and rear ends of the trapezoidal blocks on both sides are fixedly connected to connecting blocks, and guide rods penetrate through the interior of multiple connecting blocks. The upper and lower ends of multiple guide rods are respectively fixedly connected to the upper and lower ends of the connecting compartment.

[0018] As a further improvement to this technical solution, the bottom ends of the trapezoidal blocks on both sides are abutted by baffles, and the baffles on both sides are fixedly connected to the two sides of the square bin on the side closest to each other.

[0019] In the third approach, to limit the amount of pollen affected by airflow, the harvested pollen needs to be transferred intermittently.

[0020] As a further improvement to this technical solution, the collecting mechanism includes impeller two. The outer sides of the two impellers on both sides are rotatably connected to the inner side of the processing cylinder. The middle of the two impellers on both sides is fixedly connected to a transmission rod. The rear ends of the transmission rods on both sides pass through the processing cylinder and are fixedly connected to impeller three. The outer sides of the two impeller three are rotatably connected to a vertical plate. The vertical plates on both sides are provided with a connection hole on the side closer to each other, and the processing cylinder on both sides is provided with a discharge port on the side farther away from each other.

[0021] Based on this, in order to allow the harvested pollen to leave the processing cylinder through the discharge port, it is necessary to restrict the rotation direction of impeller three.

[0022] As a further improvement to this technical solution, multiple cavities are provided inside the upright plates on both sides. An arc-shaped plate is rotatably connected to the open end of each of the multiple cavities. A sliding frame is slidably connected to the far end of each of the multiple arc-shaped plates. A limiting cylinder is slidably connected to the outside of each of the multiple sliding frames. The far end of each of the multiple limiting cylinders is fixedly connected to the closed end inside the cavity. An airbag is provided inside each of the multiple limiting cylinders.

[0023] Secondly, in order to guide the airflow within the connecting chamber and prevent the airflow from coming into contact with the isolated pollen, the interior of the connecting chamber needs to be partitioned.

[0024] As a further improvement to this technical solution, baffles are fixedly connected to both the upper and lower sides of the processing cylinders on both sides. The side of the baffles away from the processing cylinders is fixedly connected to the upper and lower parts of the connecting chamber respectively. The front ends of the processing cylinders on both sides are fixedly connected to the rear ends of the perforated plate. The front ends of the perforated plates on both sides are fixedly connected to the front end of the connecting chamber. The rear ends of the processing cylinders on both sides are fixedly connected to the front ends of the vertical plate. The rear ends of the vertical plates on both sides are fixedly connected to the rear ends of the connecting chamber.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. In this pine pollen harvesting device, a fan promotes airflow, thereby using the airflow to actively detach pollen from the flower spike. This prevents the flower spike from falling and being wasted due to excessive inertial force caused by shaking the branches. At the same time, the rotating mechanism can make flexible contact with the flower spike, effectively knocking off the pollen without damaging it. This avoids the need for an excessively large fan to provide sufficient airflow, thus achieving the goal of efficient pollen harvesting. In addition, it prevents the device from being unsuitable for carrying or outdoor use due to the fan being too large.

[0027] 2. In this pine pollen harvesting device, the lifting mechanism can be driven to make reciprocating linear motion by the change of air pressure when the rotating mechanism is working, thereby meeting the pollen harvesting needs of pine branches at different heights and reducing the difficulty of pine pollen harvesting.

[0028] 3. In this pine pollen harvesting device, the collection mechanism can isolate and transfer the pollen entering the processing cylinder in batches to prevent the processing cylinder from clogging the perforated plate due to excessive pollen after long-term use, thereby preventing interference with the normal passage of air. In addition, it can effectively extend the single-use time of the device. Attached Figure Description

[0045] 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.

[0046] When harvesting pine pollen, manually shaking the branches may cause the flower spikes to fall due to the large inertial force. Furthermore, shaking the branches cannot effectively ensure the efficiency of pollen shedding. Pollen at higher points on the branches is also difficult to harvest. In addition, a large amount of pollen that has already been harvested may affect the normal airflow due to its large size when subjected to subsequent airflow.

[0047] Therefore, the present invention provides a pine pollen harvesting device, see [link to device]. Figures 1-3 As shown, it includes a connecting chamber 1, with fans 2 installed on both sides of the front end of the connecting chamber 1, and hollow columns 3 fixedly connected to both sides of the top of the connecting chamber 1. Multiple air inlets 4 are opened inside the hollow columns 3 on both sides.

[0048] During operation, the device is moved close to the pine pollen by the rod at the bottom of the connecting chamber 1. Then, with the help of the battery pack, the fan 2 drives the airflow, which causes the pollen to detach from the flower spike. The pollen is then introduced into the hollow column 3 through the air inlets 4 evenly distributed on the surface of the hollow column 3, thus temporarily completing the harvesting of pine pollen. This avoids the waste of pollen caused by some flower spikes falling directly under the action of large inertial force when manually shaking the branches to accelerate the detachment of pollen from the flower spike.

[0049] Secondly, see Figures 1-5 As shown, a rotating mechanism 5 is provided on the outer side of the hollow columns 3 on both sides, and a lifting mechanism 6 is provided at the top center of the connecting compartment 1. A horizontal plate 7 is provided at the top of the lifting mechanism 6, and the two ends of the horizontal plate 7 are respectively located on the side close to the rotating mechanism 5 on both sides.

[0050] The rotating mechanism 5 includes a connecting ring 501. The inner sides of the two connecting rings 501 are slidably connected to the outer side of the hollow column 3. The front ends of the two connecting rings 501 are fixedly connected to the air chambers 502. The air chambers 502 are rotatably connected to the inside of the two air chambers 502. The middle of the two impellers 503 is fixedly connected to the middle of the two impellers 503. The front ends of the two rotating rods 504 pass through the air chambers 502 and are fixedly connected to the brushes 505. The outer ends of the brushes 505 are rotatably connected to the front ends of the air chambers 502. The two air chambers 502 are connected to the fan 2 through the air pipes 506.

[0051] During operation, the airflow from the blower 2 into the hollow column 3 and connecting chamber 1 is introduced into the air chamber 502 through the air pipe 506. As air is continuously injected and discharged, the impeller 503 is driven to rotate the rotating rod 504. The rotating rod 504 further rotates the brush 505, which uses the flexible contact between the brush 505 and the flower spike to knock off the pollen, ensuring the separation efficiency of pollen and flower spike. In conjunction with the small-power, small-volume blower 2, pollen harvesting can be effectively completed, making the device easier to carry and use outdoors.

[0052] Further, see Figure 2 As shown, the bottom ends of the connecting rings 501 on both sides are abutted by blocks 12 on the front and back sides, and the blocks 12 on the front and back sides are fixedly connected to the front and back sides of the hollow columns 3 on both sides respectively.

[0053] During operation, the stop block 12 can block the connecting ring 501 to prevent the connecting ring 501 from moving too far downward under the action of gravity and colliding with the fan 2.

[0054] In addition, see Figures 3-8As shown, the lifting mechanism 6 includes a hollow cylinder 601. The bottom end of the hollow cylinder 601 is fixedly connected to the middle of the top of the connecting chamber 1. Both sides of the air chamber 502 are connected to the hollow cylinder 601 through the second air pipe 602. A push rod 603 is slidably connected inside the hollow cylinder 601. The top end of the push rod 603 passes through the hollow cylinder 601 and is fixedly connected to the bottom of the horizontal plate 7. The two ends of the horizontal plate 7 are respectively fixedly connected to the side of the two connecting rings 501 that are close to each other. A square chamber 604 is fixedly connected to the middle of the connecting chamber 1. A sliding plate 605 is slidably connected inside the square chamber 604. Trapezoidal blocks 606 are slidably connected to both sides of the square chamber 604. Trapezoidal blocks 607 are slidably connected to the side of the two trapezoidal blocks 606 that are far apart from each other. An air outlet 608 is opened at the lower rear end of the square chamber 604.

[0055] During operation, air discharged from air chamber 502 can continue to enter hollow cylinder 601 through air pipe 2 602. Since trapezoidal block 2 607 and trapezoidal block 1 606 are in contact via an inclined plane, under the influence of gravity, trapezoidal block 2 607 can temporarily block the sliding plate 605 from moving downwards along the square chamber 604 via trapezoidal block 1 606. Therefore, with the continuous operation of fan 2, the air pressure inside hollow cylinder 601 gradually increases. This allows push rod 603 to move slowly upwards along hollow column 3 via horizontal plate 7, driven by air pressure, through the horizontal plate 7 and connecting rings 501 on both sides. At this time, air chamber 502, impeller 1 503, rotating rod 504, and brush 505 connected to connecting ring 501 can also move synchronously. This allows rotating mechanism 5 to flexibly contact flower spikes at different heights and to achieve uniform contact with the flower spikes. The distributed air inlets 4, when combined, can significantly reduce the difficulty of harvesting pollen at high altitudes. When the push rod 603 moves upward to its limit position, under the continued increase of air pressure inside the hollow cylinder 601, the slide plate 605 can apply a pushing force to the trapezoidal block 606, causing the trapezoidal block 606 to gradually overcome the pushing force applied by the trapezoidal block 607, until the slide plate 605 completely passes through the area where the trapezoidal block 606 is located. At this time, under the action of greater air pressure, the slide plate 605 can quickly move downward to the area where the air outlet 608 is located, and then the air outlet 608 can quickly discharge the square chamber 604 to provide power for the subsequent movement of the collection mechanism 11. At the same time, as the air pressure decreases rapidly, the push rod 603 can also drive the horizontal plate 7 and the rotating mechanism 5 to move downward, thus preparing for the subsequent upward movement.

[0056] Furthermore, refer to Figure 7 and Figure 8 As shown, a magnet 609 is fixedly connected to the middle of the bottom of the connecting compartment 1, and a magnet 610 is fixedly connected to the bottom of the slide plate 605, with magnet 609 facing magnet 610.

[0057] During operation, the repulsion between like poles of magnet 609 and magnet 610 allows air above the slide plate 605 to be quickly expelled through the air outlet 608, pushing the slide plate 605 through the area where the trapezoidal block 606 is located and returning to the initial position. This allows the hollow cylinder 601 to accumulate air again, ensuring that the push rod 603 can drive the rotating mechanism 5 to actively perform vertical reciprocating linear motion, so that the rotating mechanism 5 can continuously knock down pollen from different directions and heights of the pine tree.

[0058] Secondly, refer to Figure 6 As shown, both ends of the trapezoidal blocks 607 on both sides are fixedly connected to connecting blocks 611. Guide rods 612 pass through the interior of multiple connecting blocks 611. The upper and lower ends of multiple guide rods 612 are fixedly connected to the upper and lower ends of the connecting chamber 1, respectively.

[0059] During operation, the connecting block 611 and guide rod 612 can work with the connecting chamber 1 to restrict the movement direction of trapezoidal block 2 607, so as to prevent trapezoidal block 2 607 from undergoing horizontal displacement when acted upon by trapezoidal block 1 606.

[0060] Furthermore, refer to Figure 8 As shown, the bottom ends of the trapezoidal blocks 607 on both sides are abutted by baffles 613, and the baffles 613 on the side closest to each other are fixedly connected to the two sides of the square bin 604.

[0061] During operation, the baffle 613 can limit the extreme downward movement of trapezoidal block 607 to prevent trapezoidal block 607 from moving too far downward and completely pushing trapezoidal block 606 into the central area of ​​square bin 604.

[0062] In addition, see Figure 6 , Figure 7 and Figure 9 As shown, processing cylinders 8 are provided on both sides of the interior of the connecting chamber 1. The front ends of the processing cylinders 8 on both sides are connected to the fan 2 through perforated plates 9. Exhaust holes 10 are provided on both sides of the rear end of the connecting chamber 1. Collection mechanisms 11 are provided inside the processing cylinders 8 on both sides. The processing cylinders 8 on both sides are connected to the hollow column 3.

[0063] During operation, since the processing cylinder 8 and the hollow column 3 are connected, with the cooperation of the perforated plate 9, the air and pollen inside the hollow column 3 can only pass through the perforated plate 9 after entering the processing cylinder 8 and be transported to the air chamber 502 by the fan 2 along the air pipe 506. At the same time, the pollen trapped inside the processing cylinder 8 can be intermittently isolated and transferred by the collection mechanism 11.

[0064] Specifically, refer to Figure 7 , Figure 9 and Figure 10As shown, the collecting mechanism 11 includes impeller 2 1101. The outer sides of the two impellers 2 1101 are rotatably connected to the inner side of the processing cylinder 8. The middle of the two impellers 2 1101 is fixedly connected to the transmission rod 1102. The rear ends of the two transmission rods 1102 pass through the processing cylinder 8 and are fixedly connected to impeller 3 1103. The outer sides of the two impellers 3 1103 are rotatably connected to the vertical plate 1104. The two vertical plates 1104 are provided with a connection hole 1105 on the side closer to each other, and the two processing cylinders 8 are provided with a discharge port 1106 on the side farther away from each other.

[0065] During operation, the impeller 1101 divides the interior of the processing cylinder 8 into multiple spaces. Therefore, air and pollen entering the processing cylinder 8 from the hollow column 3 can only remain in one or two of these spaces. Correspondingly, after being sieved through several small holes in the upper region of the perforated plate 9, the air can enter the blower 2, while the collected pollen is retained in one or two corresponding spaces. At this time, as the air intermittently discharged from the outlet 608 enters the vertical plate 1104 along the connecting hole 1105, and then pushes the impeller 1103 as it is discharged to the outside through the exhaust hole 10, the transmission rod 1102 can synchronize the impeller 1101 with the impeller 1103. The rotation alters the space connected to the hollow column 3 and separated by impeller 2 1101. The space where pollen was originally located can then come into contact with the discharge port 1106. Under the influence of gravity, most of the pollen can slide away from the processing cylinder 8 through the discharge port 1106, thus achieving the purpose of batch isolation and transfer of the collected pollen. This prevents excessive pollen from being collected in a certain space, which could then clog the orifice plate 9 and affect normal airflow after being subjected to airflow. Furthermore, due to the intermittent movement of impeller 2 1101, the amount of pollen inside the processing cylinder 8 will never be excessive. Therefore, the device can be used continuously for a long time, avoiding the need for manual transfer of the collected pollen after a period of use.

[0066] Additionally, refer to Figure 11 As shown, multiple cavities 1107 are provided inside both upright plates 1104. The open ends of the multiple cavities 1107 are rotatably connected to arc-shaped plates 1108. The ends of the multiple arc-shaped plates 1108 that are away from each other are slidably connected to sliding frames 1109. Limiting cylinders 1110 are slidably connected to the outside of the multiple sliding frames 1109. The ends of the multiple limiting cylinders 1110 that are away from the sliding frames 1109 are fixedly connected to the closed ends inside the cavities 1107. Airbags 1111 are provided inside the multiple limiting cylinders 1110.

[0067] During operation, the airbag 1111 can apply a thrust to the sliding frame 1109, causing the sliding frame 1109 to move along the limiting cylinder 1110, thereby pushing one side of the arc plate 1108 away from the cavity 1107. In turn, the evenly distributed arc plates 1108 can restrict the rotation direction of the impeller 3 1103, ensuring that it can only rotate in one direction. This prevents the impeller 3 1103 from oscillating back and forth under the action of airflow, which would prevent the collected pollen from leaving the processing cylinder 8. In addition, the sliding frame 1109 and the arc plate 1108 are connected by a cylindrical rod, so that when the arc plate 1108 rotates around the connection between it and the cavity 1107, the sliding frame 1109 can move along the arc plate 1108 through the cylindrical rod, thereby avoiding motion interference between the arc plate 1108 and the sliding frame 1109.

[0068] Furthermore, refer to Figure 7 and Figure 9 As shown, baffles 1112 are fixedly connected to both the upper and lower sides of the two processing cylinders 8. The side of the baffles 1112 away from the processing cylinder 8 is fixedly connected to the upper and lower parts of the connecting chamber 1 respectively. The front ends of the two processing cylinders 8 are fixedly connected to the rear ends of the perforated plate 9. The front ends of the two perforated plates 9 are fixedly connected to the front end of the connecting chamber 1. The rear ends of the two processing cylinders 8 are fixedly connected to the front ends of the vertical plate 1104. The rear ends of the two vertical plates 1104 are fixedly connected to the rear ends of the connecting chamber 1.

[0069] During operation, the contact between the baffle 1112, the perforated plate 9, the vertical plate 1104 and the connecting chamber 1 can divide the interior of the connecting chamber 1 into multiple non-communicating areas. This ensures that the air discharged from the air outlet 608 can only enter the vertical plate 1104 through the connecting hole 1105 and be discharged through the exhaust hole 10. At the same time, it also ensures that the pollen leaving the processing cylinder 8 through the discharge port 1106 will not be affected by the airflow again, thereby preventing the collected pollen from drifting out through the gaps of the side doors on both sides of the connecting chamber 1 under the action of the airflow.

[0070] Working Principle: During operation, outside air is forced into the hollow column 3 and processing cylinder 8 through the air inlet 4 by the blower 2. After being screened by the perforated plate 9, the air then enters the air chamber 502 through the retractable air pipe 506 driven by the blower 2. At this time, the impeller 503 inside the air chamber 502 can drive the brush 505 to rotate under the action of the airflow via the rotating rod 504. Simultaneously, the air discharged from the air chamber 502 can continue to enter the hollow cylinder 601 through the retractable air pipe 602, increasing the air pressure inside the hollow cylinder 601. This pushes the push rod 603, causing the horizontal plate 7 and connecting ring 501 to move upward. As the brush 505 rotates, it can gently agitate multiple flower spikes in the vertical direction, accelerating the detachment of pollen from their respective flower spikes at different heights. This allows the pollen to enter the air chamber 4 with the air. The hollow column 3 and the processing cylinder 8 are fed into the hollow cylinder 601. After the push rod 603 moves to its limit position, as the air pressure inside the hollow cylinder 601 continues to increase, the sliding plate 605 can move down to overcome the obstruction of trapezoidal block 1 606 and trapezoidal block 2 607. When it moves to the area where the air outlet 608 is located, the accumulated air can be quickly discharged. Then, through the connecting hole 1105, the discharged air can enter the vertical plate 1104 to apply a thrust to the impeller 3 1103. Through the impeller 3 1103 and the transmission rod 1102, the impeller 2 1101 can be driven to rotate unidirectionally along the inner surface of the processing cylinder 8. At this time, the pollen that is blocked by the combined action of the perforated plate 9, the impeller 2 1101 and the processing cylinder 8 can gradually leave the processing cylinder 8 through the discharge port 1106 as the impeller 2 1101 rotates, so as to be temporarily stored separately.

[0071] In summary, through the flexible contact between the brush 505 and the flower spike, and the reciprocating up-and-down movement of the push rod 603 driving the horizontal plate 7, connecting ring 501, and brush 505 and other related components, the flower spikes at different heights can be fully agitated. This, combined with the low-power, small-volume fan 2, effectively collects pollen from the surface of the flower spikes, preventing the flower spikes from falling and causing waste. At the same time, the use of lightweight, hollow, and small-volume components also facilitates the outdoor use of the device. Furthermore, the intermittent transfer of pollen collected inside the processing cylinder 8 can prevent it from affecting the normal flow of air, significantly extending the single-use time of the device.
