Description

Technical Field

[0001] This application relates to pollen collection technology, and more particularly to a pollen collection device for maize breeding. Background Technology

[0002] In the process of breeding hybridization experiments of silage corn, artificial pollination is usually required to improve the pollination effect. Before artificial pollination, pollen needs to be collected from the stamens of the male parent corn.

[0003] Currently, a common method for collecting corn pollen is as follows: First, bend the tassel to a bent position. Then, place a paper bag over the corn tassel and pinch the opening of the paper bag tightly. Next, shake the tassel so that the pollen on the tassel falls into the paper bag. The paper bag collects the pollen, and finally, remove the paper bag to complete the pollen collection.

[0004] However, in actual pollen collection, bending the tassels is not only slow, but also makes the tassels prone to breakage due to their brittleness. Additionally, the height of silage corn makes it difficult for workers to place paper bags over the tassels. Utility Model Content

[0005] This application provides a pollen collection device for maize breeding, which solves the problems of slow speed, easy breakage of tassels, and inconvenience for workers to put paper bags on tassels during existing maize pollen collection.

[0006] This application provides a pollen collection device for maize breeding, including a collection cover with an opening at the lower end. The inner wall of the collection cover is provided with an inverted U-shaped cavity. The cavity is composed of a vertical cavity I, a horizontal cavity and a vertical cavity II, and the vertical cavity I is connected to the vertical cavity II through the horizontal cavity.

[0007] The side wall of the vertical cavity I has an air vent I that communicates with the inside of the collection hood. The inside of the vertical cavity I is equipped with a filter screen for intercepting pollen. The lower end of the vertical cavity I is detachably connected to a collection bottle via a vertical tube.

[0008] The side wall of the vertical cavity II has an air vent II that communicates with the inside of the collection hood, and the air vent II is equipped with a blowing structure.

[0009] Optionally, the interior of the vertical cavity I is provided with inclined partitions, the edges of which are sealed to the inner wall of the vertical cavity I, and the partitions are provided with an installation port located below the air outlet I, and the filter screen is fixed at the installation port.

[0010] Optionally, the lower end of the vertical cavity I is connected to a bucket-shaped collection bin, the lower end of the collection bin is connected to the vertical pipe, and the collection bottle is detachably and sealed to the lower end of the vertical pipe through a threaded structure.

[0011] Optionally, the lower part of the vertical pipe is connected to a support structure for contacting the ground.

[0012] Optionally, the support structure includes a mounting base and a support tube, wherein the mounting base is fixedly connected to the vertical tube;

[0013] The support tube passes through the connecting seat and is slidably connected to the connecting seat. The support tube is parallel to the vertical tube, and a support plate is fixed at the lower end of the support tube.

[0014] The mounting base is equipped with bolts that can tighten the support tube.

[0015] Optionally, the air vent I is provided with a mesh plate for intercepting impurities.

[0016] Optionally, the blowing structure includes a fan blade assembly located at the air outlet II, the fan blade assembly being connected to a motor capable of driving it to rotate, and the motor being fixed inside the vertical cavity II;

[0017] The motor is connected to a battery that supplies power to it, and the battery is installed inside the support tube.

[0018] The pollen collection device for maize breeding provided in this application features a collection hood with an opening at the bottom. The inner wall of the collection hood has an inverted U-shaped cavity, which consists of a vertical cavity I, a horizontal cavity, and a vertical cavity II. Vertical cavity I is connected to vertical cavity II via the horizontal cavity. A vent I, communicating with the interior of the collection hood, is located on the side wall of vertical cavity I. A filter screen for intercepting pollen is installed inside vertical cavity I. A collection bottle is detachably connected to the lower end of vertical cavity I via a vertical tube. A vent II, communicating with the interior of the collection hood, is located on the side wall of vertical cavity II. A blowing structure is located at vent II. During use, the operator stands on the ground, holds a vertical pole, moves the collection hood above the tassel, lowers the hood, and places it directly over the tassel. Then, the blowing structure is activated, blowing air onto the tassel at vent II to lift the pollen. Vertical cavity I is connected to vertical cavity II via horizontal cavity. Therefore, after the blowing structure blows air onto the tassel at vent II, a circulating airflow is formed between vertical cavity I, horizontal cavity, vertical cavity II, and the inside of the collection hood. Negative pressure is generated within vertical cavity I, horizontal cavity, and vertical cavity II. Vent I draws in the gas inside the collection hood, thus drawing the pollen blown up inside the collection hood into vertical cavity I. Under the action of the filter, the pollen is intercepted in vertical cavity I, and the dust settles to the bottom of vertical cavity I and flows into the collection bottle through the vertical pipe, completing the corn pollen collection. Compared with existing corn pollen collection methods, this method eliminates the need to bend the tassel. Workers simply stand on the ground, hold the vertical pipe, place the collection hood over the tassel, and then activate the blowing structure to complete the pollen collection. This is not only convenient and fast, but also avoids breaking the tassel. Furthermore, holding the vertical pipe makes it easier for workers to place the collection hood over the tassel.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0027] like Figures 1-5 As shown:

[0028] An embodiment of this application provides a pollen collection device for maize breeding, comprising a collection cover 1 with an open lower end. The inner wall of the collection cover 1 is provided with an inverted U-shaped cavity 2, which is composed of a vertical cavity I 201, a horizontal cavity 202, and a vertical cavity II 203. The vertical cavity I 201 is connected to the vertical cavity II 203 through the horizontal cavity 202. Specifically, the vertical cavity I 201 is connected to the horizontal cavity 202, and the horizontal cavity 202 is connected to the vertical cavity II 203.

[0029] The side wall of the vertical cavity I201 has an air vent I3 that communicates with the interior of the collection hood 1, meaning that the vertical cavity I201 is connected to the interior of the collection hood 1 through the air vent I3. The interior of the vertical cavity I201 is equipped with a filter 4 for intercepting pollen. The lower end of the vertical cavity I201 is detachably connected to a collection bottle 6 via a vertical tube 5, and the collection bottle 6 is used to collect pollen. Specifically, the upper end of the vertical rod is sealed and fixedly connected to the lower end of the vertical cavity I201, and the lower end of the vertical rod is detachably and sealedly connected to the collection bottle 6.

[0030] The side wall of the vertical cavity II203 has an air vent II7 that communicates with the inside of the collection cover 1. That is, the vertical cavity II203 is connected to the inside of the collection cover 1 through the air vent II7. A blowing structure 8 is provided at the location of the air vent II7.

[0031] During use, the operator stands on the ground and holds a vertical pole, then moves the collection cover 1 above the tassel. Next, the collection cover 1 is lowered and placed over the tassel. Then, the blowing structure 8 is activated. The blowing structure 8 blows air onto the tassel inside the collection cover 1 at the air inlet II 7, blowing pollen from the tassel towards the air inlet I 3. Since the vertical cavity I 201 is connected to the horizontal cavity 202, and the horizontal cavity 202 is connected to the vertical cavity II 203, after the blowing structure 8 blows air onto the tassel at the air inlet II 7, the air inlet II 7 draws air from the vertical cavity II 203, and the vertical cavity II 203 draws air from the horizontal cavity 202. The horizontal cavity 202 draws air from the vertical cavity I 201, and the vertical cavity I 201 draws air from the inside of the collection hood 1 through the air outlet I 3. A circulating airflow is formed between the vertical cavity I 201, the horizontal cavity 202, the vertical cavity II 203 and the inside of the collection hood 1. That is, air blows from one side of the collection hood 1 and air is drawn from the other side of the collection hood 1. This draws the pollen scattered in the collection hood 1 into the vertical cavity I 201. Under the action of the filter screen 4, the pollen is intercepted in the vertical cavity I 201. The dust finally settles to the bottom of the vertical cavity I 201 and flows into the collection bottle 6 through the vertical pipe 5, completing the collection of corn pollen.

[0032] The pollen collection device for maize breeding provided in this embodiment features a collection hood 1 with an opening at the bottom. The inner wall of the collection hood 1 has an inverted U-shaped cavity 2, which consists of a vertical cavity I 201, a horizontal cavity 202, and a vertical cavity II 203. The vertical cavity I 201 is connected to the vertical cavity II 203 through the horizontal cavity 202. The side wall of the vertical cavity I 201 has an air vent I 3 that communicates with the inside of the collection hood 1. The inside of the vertical cavity I 201 is equipped with a filter screen 4 for intercepting pollen. The lower end of the vertical cavity I 201 is detachably connected to a collection bottle 6 via a vertical tube 5. The side wall of the vertical cavity II 203 has an air vent II 7 that communicates with the inside of the collection hood 1. An air blowing structure 8 is provided at the air vent II 7. This allows for pollen collection without bending the tassels. The operator simply stands on the ground, holds up the vertical tube 5, places the collection hood 1 over the tassels, and then activates the air blowing structure 8. This method is not only convenient and fast but also avoids the problem of breaking the tassels. In addition, after the staff holds up the vertical tube 5, it is easy to put the collection cover 1 on the male ear.

[0033] In some embodiments of this application, the interior of the vertical cavity I 201 is provided with inclined partitions 9. The edges of the partitions 9 are sealed to the inner wall of the vertical cavity I 201, that is, the partitions 9 divide the vertical cavity I 201 into two independent cavities. The two cavities are composed of cavity I 11 and cavity II 12. Cavity I 11 is below the partitions 9, and cavity II 12 is above the partitions 9. The lower end of cavity I 11 is connected to the vertical rod. The partitions 9 have an installation port 10 located below the air vent I 3, and the filter screen 4 is fixed at the installation port 10. Specifically, the filter screen 4 has a plate-like structure and is embedded in the installation port 10, so that the filter screen 4 is also inclined.

[0034] When in use, after the blowing structure 8 is activated, the pollen blown up by the collection hood 1 enters the cavity 111 from the air outlet 13 with the flowing air. Then, the pollen flows downward in the vertical cavity 1201 with the flowing air and flows to the filter screen 4. The air passes through the filter screen 4 and enters the cavity 212 and flows from the cavity 212 to the horizontal cavity 202, circulating. The pollen is intercepted by the filter screen 4 in the cavity 11 and finally falls into the vertical tube 5.

[0035] In this embodiment, the filter 4 is placed below the air vent I3, and the filter 4 and the air vent I3 are staggered. After the airflow carrying pollen enters the cavity I11, it first flows downward. Then, the airflow carrying pollen turns back at the installation port 10 and passes through the filter 4 to flow upward in the cavity II12. At the same time, the filter 4 intercepts the pollen in the cavity I11. After the airflow turns back in the vertical cavity I201, the pollen sinking effect can be improved.

[0036] In some embodiments of this application, the lower end of the vertical cavity I 201 is connected to a bucket-shaped collection bin 13, which facilitates the entry of pollen from the vertical cavity I 201 into the vertical pipe 5. The lower end of the collection bin 13 is sealed and fixedly connected to the vertical pipe 5, and the collection bottle 6 is detachably and sealed to the lower end of the vertical pipe 5 through a threaded structure.

[0037] Specifically, the lower end of the vertical tube 5 is provided with an external thread structure, and the upper part of the collection bottle 6 is provided with an internal thread structure. The external thread structure and the internal thread structure are engaged and connected.

[0038] When in use, the staff only needs to hold the collection bottle 6 with one hand and the vertical tube 5 with the other hand, and then rotate the collection bottle 6 to disassemble and assemble it.

[0039] In some embodiments of this application, the lower part of the vertical pipe 5 is connected to a support structure 14 for contacting the ground.

[0040] In this embodiment, by setting a support structure 14 that is in contact with the ground, the support structure 14 can be placed on the ground when collecting pollen. The support structure 14 supports the vertical tube 5, and the vertical tube 5 supports the collection cover 1. After the collection cover 1 is put on the male ear, the staff only needs to hold the vertical pole to ensure that the vertical pole is vertically distributed to carry out pollen collection. Thus, when collecting pollen, the operator does not need to lift the vertical tube 5 by hand, which reduces the staff's arm strength and workload.

[0041] In some embodiments of this application, the support structure 14 includes a mounting base 1401 and a support tube 1402, with the mounting base 1401 fixedly connected to the vertical tube 5. Specifically, the mounting base 1401 is fitted onto the vertical tube 5 and fixedly connected to it.

[0042] The support tube 1402 passes through the connecting seat and is slidably connected to the connecting seat. The support tube 1402 is parallel to the vertical tube 5, and the lower end of the support tube 1402 is fixed with a support plate 1403.

[0043] The mounting base 1401 is provided with bolts 1404 that can press the support tube 1402 tightly.

[0044] In this embodiment, the mounting base 1401 is provided with a through hole 1405 that runs vertically through it. The support tube 1402 passes through the through hole 1405 and is slidably connected to the through hole 1405. One end of the mounting base 1401 is provided with a circular hole 1406 that communicates with and is perpendicular to the through hole 1405. The circular hole 1406 is connected to an internally threaded sleeve 1407 that is concentric with it and fixedly connected to the mounting base 1401. The bolt 1404 engages with the internally threaded sleeve 1407 and extends into the circular hole 1406.

[0045] In use, the support plate 1403 is in contact with the ground, supporting the support pipe 1402, which in turn supports the vertical pipe 5. When collecting silage corn of different heights, workers can manually rotate the bolt 1404 away from the support pipe 1402, then move the support pipe 1402 up and down to adjust its position to accommodate silage corn of different heights. Finally, manually rotating the bolt 1404 again will lock the support pipe 1402, completing the position adjustment. This allows the overall length of the vertical pipe 5 and the support pipe 1402 to be adjusted according to the height of the silage corn, ensuring that the support plate 1403 is in contact with the ground after the collection cover 1 is placed on the tassel.

[0046] In some embodiments of this application, a mesh plate 15 for intercepting impurities is provided at the air outlet I3 position to prevent larger impurities from entering the vertical cavity I201 and blocking the vertical pipe 5.

[0047] In some embodiments of this application, the blowing structure 8 includes a fan blade assembly 801, which is located at the air outlet II 7. The fan blade assembly 801 is connected to a motor 802 that can drive it to rotate, and the motor 802 is fixed inside the vertical cavity II 203.

[0048] The motor 802 is connected to a battery 16 that supplies power to it. The battery 16 is installed inside the support tube 1402 to reduce space occupation.

[0049] In this embodiment, the vertical pipe 5 is equipped with a control switch for controlling the opening and closing of the motor 802, and the battery 16 is connected to a charging port and a power indicator. The control switch, charging port, and power indicator are all prior art and will not be described in detail.

[0050] When in use, the operator manually operates the control switch to control the opening and closing of the motor 802. When the motor 802 is started, it drives the fan blade assembly 801 to rotate and blow air. When the motor 802 is turned off, it stops rotating, and the fan blade assembly 801 also stops rotating, thus stopping the blowing operation.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
