Description

Technical Field

[0001] This utility model belongs to the technical field of pollen collection equipment, specifically relating to a field pollen collection device with high efficiency and high viability. Background Technology

[0002] Pollen plays a crucial role in plant sexual reproduction. The paternal genetic information transmitted after pollen germination is key to seed formation. Pollen collection, storage, and viability are fundamental to seed production and are essential steps in male-sterile line breeding and hybrid seed production. Before hybrid seed production, a large quantity of paternal pollen is needed for hybridization. For example, in hybrid breeding of crops such as corn and rice, collecting pollen from superior paternal parents for artificial pollination can significantly improve the yield and resistance of offspring. Therefore, how to collect pollen and maintain its viability is crucial for hybrid seed production.

[0003] Currently, pollen collection methods in the field mainly include manual pollen collection, mechanical vibration pollen collection, or air-suction pollen collection. Taking rice as an example, manual pollen collection is labor-intensive and inefficient, making it unsuitable. Mechanical vibration pollen collection can easily damage rice plants, ultimately leading to reduced yield. Air-suction pollen collection, on the other hand, uses airflow to adsorb pollen and combines it with a cooling system to ensure high pollen viability, making it suitable for pollen collection in hybrid crops such as hybrid rice or crops requiring artificial pollination.

[0004] In the existing technology, the working principle of the air-suction pollen collection device that can be practically applied in the field is to suck the pollen into the cooling chamber by a fan for cooling. However, the heat generated by the fan will affect the temperature of the cooling chamber, and the pollen collected will be scattered in the cooling chamber, requiring manual cleaning and collection again. This operation is cumbersome and will also cause some damage to the pollen, reducing its viability. Therefore, this utility model provides a field pollen high-efficiency and high-viability collection device to solve the above technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a highly efficient and viable pollen collection device for the field in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A field pollen collection device with high efficiency and high viability includes a collection chamber and a cooling chamber, and also includes a collection cloth. One end of the collection cloth passes through the collection chamber and extends into the cooling chamber, and is wound up on a collection roller. The collection cloth located in the collection chamber is positioned to block the pollen transport path of the collection chamber, and is used to intercept the inhaled pollen and transport the pollen to the cooling chamber for winding.

[0008] As a further optimization of this utility model, the collection chamber is flat, and the collection cloth extends through the two flat surfaces of the collection chamber; the cooling chamber is used to refrigerate and dry the collected pollen.

[0009] As a further optimization of this utility model, the collecting cloth is a breathable cotton cloth, meltblown cloth, or non-woven cloth.

[0010] As a further optimization of this utility model, the surface of the collecting cloth is inclined and set at an acute angle with the pollen transport direction, so as to collect pollen on the collecting cloth with maximum efficiency.

[0011] As a further optimization of this utility model, the collection chamber is equipped with a fan and a powder inlet pipe, which are respectively arranged on both sides of the collection cloth.

[0012] As a further optimization of this utility model, the inlet end of the pollen inlet pipe is also provided with a pollen suction hood, and the pollen inlet pipe and / or the pollen suction hood is provided with a filter screen, which is used to filter out larger impurities such as anthers, leaves, and insects when pollen is inhaled.

[0013] As a further optimization of this utility model, the take-up roller is provided with a drive mechanism.

[0014] As a further optimization of this utility model, the other end of the collecting cloth is wound onto the unloading roller, and the collecting roller and the unloading roller are detachably connected to the fixed frame.

[0015] As a further optimization of this utility model, the collecting surface of the collecting cloth is provided with a number of raised ribs, which are arranged in a crisscross pattern to form a cavity for containing pollen, thereby reducing the squeezing effect on the pollen and ensuring the viability of the pollen.

[0016] As a further optimization of this utility model, the raised ribs located at the edge of the collecting cloth are continuous and uninterrupted, and the raised ribs between the other two adjacent chambers are provided with holes that allow pollen to leak into the adjacent chambers.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1) The device of this utility model can be widely used in the mechanized collection and storage of pollen from gramineous crops or crops that require artificial pollination. It can improve the pollen collection efficiency while maximizing the pollen viability and pollination set rate, thus meeting the pollen demand of large-scale production of hybrid crops.

[0019] 2) This utility model draws in pollen from the target crop through a collection chamber. The pollen is collected and adheres to the collection cloth under suction. The collection chamber is flat, which reduces the impact of the fan heat on the cooling chamber and improves the utilization efficiency of the cooling source. As the collection cloth is transported, it enters the cooling chamber. The collection cloth containing the pollen is cooled quickly and evenly during the transport process inside the cooling chamber. After cooling, the pollen collected on the collection cloth is rolled up and stored in the cooling chamber, which can maximize the preservation of pollen viability. Attached Figure Description

[0027] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] like Figure 1-6 As shown, a field pollen collection device with high efficiency and high viability includes a collection chamber 11 and a cooling chamber 2, as well as a collection cloth 3. One end of the collection cloth 3 passes through the collection chamber 11 and extends into the cooling chamber 2, and is wound up on a take-up roller 41. The collection cloth 3 located in the collection chamber 11 blocks the pollen transport path of the collection chamber 11, and is used to intercept the inhaled pollen and transport the pollen to the cooling chamber 2 for winding up.

[0029] Preferably, the collection chamber 11 is flat, and the collection cloth 3 extends through the two flat surfaces of the collection chamber 11; the cooling chamber 2 is used to refrigerate and dry the collected pollen.

[0030] It should be noted that in this embodiment, liquid CO2 or liquid N2 is used as a cooling source for refrigeration or a compressor is used for refrigeration to cool the collected pollen inside the cooling chamber 2.

[0031] The airflow driven by the fan 12 to transport pollen flows parallel to the top of the cooling chamber 2, which effectively reduces the loss of cooling source in the cooling chamber 2, improves the utilization efficiency of the cooling source, reduces the impact of the heat from the fan 12 on the cooling chamber 2, and can better maintain the low temperature inside the cooling chamber 2.

[0032] Preferably, the collecting cloth 3 is a breathable cotton cloth, meltblown cloth, or non-woven cloth.

[0033] Preferably, the surface of the collecting cloth 3 is inclined and set at an acute angle to the pollen transport direction, which facilitates the collection of pollen.

[0034] Preferably, the collection chamber 11 is equipped with a fan 12 and a powder inlet pipe 13, which are respectively arranged on both sides of the collection cloth 3.

[0035] Preferably, the powder inlet end of the powder inlet pipe 13 is also provided with a powder suction hood 14, and the powder inlet pipe 13 and / or the powder suction hood 14 are provided with a filter plate to facilitate the filtration of larger impurities mixed in with flowers, leaves and other parts when pollen is inhaled.

[0036] Preferably, the take-up roller 41 is provided with a drive mechanism.

[0037] It should be noted that, in this embodiment, the drive mechanism includes, but is not limited to, a servo motor, and also includes an integral structure composed of a servo motor and a reduction gear.

[0038] Preferably, the other end of the collecting cloth 3 is wound onto the unloading roller 42, and the unloading roller 41 and the unloading roller 42 are detachably connected to the fixed frame, which facilitates the placement and removal of the collecting cloth 3.

[0039] The device of this application can be placed on a mobile cart to collect pollen in the field. The blower 12 is turned on, and the pollen suction hood 14 is aimed at the pollen location of the target crop. The pollen of the target crop is sucked in by the suction of the blower 12 through the pollen suction hood 14, and then transported into the collection chamber 11 through the pollen inlet pipe 13. At the same time as the pollen is sucked in, the drive mechanism is started. The operation of the drive mechanism will drive the take-up roller 41 to rotate and roll up the collection cloth 3, and cause the release roller 42 to continuously release the collection cloth 3 as the collection cloth 3 is rolled up. Under the action of suction, the pollen inside the collection chamber 11 will be continuously collected and attached to the surface of the continuously conveyed collection cloth 3. As the collection cloth 3 is conveyed, the pollen will enter the cooling chamber 2. The collection cloth 3 containing the pollen will be quickly and evenly cooled during the conveying process in the cooling chamber 2. Then the pollen will be rolled up with the collection cloth 3 and stored in the cooling chamber 2.

[0040] Preferably, the collecting surface of the collecting cloth 3 is provided with a plurality of raised ribs 31, which are arranged in a crisscross pattern to form a cavity 32 for containing pollen. When the collecting cloth 3 is rolled up on the collecting roller 41, the raised ribs 31 can separate adjacent layers of collecting cloth 3, providing a certain space for the pollen and reducing the squeezing effect on the pollen.

[0041] Preferably, the raised ribs 31 located at the edge of the collecting cloth 3 are continuous and uninterrupted. The raised ribs 31 between the other two adjacent chambers 32 are provided with holes 33 that allow pollen to leak into the adjacent chambers 32. If there is a lot of pollen in a single chamber 32 or the pollen is not evenly distributed, in order to reduce the long-term squeezing effect of the collecting cloth 3 rolled into the inner layer on the pollen in the chamber 32 rolled into the outer layer, the excess pollen in the chamber 32 can be leaked out and transported to other chambers 32 through the holes 33.

[0042] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
