Description

Technical Field

[0001] This utility model relates to the field of eggplant hybridization and pollination technology, specifically to a hybridization and pollination device for eggplant. Background Technology

[0002] Pollination is a crucial step in eggplant breeding. In cross-pollination, manual flower removal is often used, which is inefficient and can affect seed purity if sterilization is not thorough. Therefore, it is essential to use pollination devices for pollination.

[0003] Currently, in the process of eggplant hybridization pollination, to ensure high pollen viability, pollination is usually carried out by manually removing the anthers. However, this method is prone to pollen leakage, which can easily spread to the stamens of different varieties, affecting the purity of eggplant seed production. Furthermore, in eggplant hybridization breeding, due to the large number of eggplant varieties, there are also many parent plants for pollination of different varieties. The existing pollination devices are all-in-one, making it difficult to thoroughly clean the pollen residue inside the device, which can easily cause different types of pollen to mix together. In addition, the existing pollination devices only have a pollen storage section. During operation, pre-treated pollen needs to be placed directly into the pollen storage section. If the pollen contains impurities, it can easily cause the pollen spray tube to become clogged, resulting in uneven pollination of the stamens and affecting the pollination efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a special hybrid pollination device for eggplant. A protective cover is provided at the end of the pollen spraying tube to prevent pollen from escaping during pollination and to improve the purity of seed production. The pollination device is designed as a structure assembled from multiple parts and made of transparent material, which facilitates observation of the pollen inside the device and makes it easy to clean the pollen remaining inside the device. A pollen collection box is provided on the top of the storage box, and a filter screen is installed between the storage box and the pollen collection box to prevent impurities in the pollen from clogging the pollen spraying tube.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hybrid pollination device for eggplant, comprising a shell, an inner cavity formed within the shell, a connector communicating with the inner cavity on one side of the shell, a connecting pipe communicating with the inner cavity on the other side of the shell, a conveying pipe communicating with the inner cavity extending through the top of the shell, a sealing plate rotatably disposed within the inner cavity and respectively cooperating with the conveying pipe and the connecting pipe, a detachable storage box, a retainer, and a pollen collection box sequentially disposed on the conveying pipe, an air bladder disposed at the end of the connecting pipe, an air inlet pipe communicating with the connecting pipe, a one-way valve fixedly disposed on the air inlet pipe, a detachable pollen spraying pipe disposed on the connector, and a protective cover disposed at the end of the pollen spraying pipe.

Figure 4 As shown, hinge seats 6 extending into the inner cavity 2 are fixedly installed on the top wall of the housing 1 and on both sides of the conveying pipe 5, and a sealing plate 7 is hinged between the two hinge seats 6.

[0022] Specifically in this embodiment, combined with Figure 2 and Figure 4 As shown, a detachable storage box 8 is provided at the top of the conveying pipe 5. Preferably, the top of the storage box 8 has an open structure. A detachable retainer 9 is provided at the top of the storage box 8. A filter screen 10 is fixedly provided on the inner wall of the retainer 9. Preferably, the filter screen 10 is a 60-mesh insect-proof screen. A detachable pollen collection box 11 is provided at the top of the retainer 9. Preferably, the pollen collection box 11 collects pollen and is directly installed on the retainer 9. The pollen is filtered through the filter screen on the retainer 9 to prevent impurities in the pollen from flowing into the pollen spray pipe 16 and causing blockage of the pollen spray pipe 16.

[0023] Specifically in this embodiment, combined with Figure 1 , Figure 3 and Figure 4 As shown, an airbag 12 is provided at the other end of the connecting pipe 4. An air inlet pipe 13 connected to the connecting pipe 4 is fixedly provided on the outer wall of the connecting pipe 4 and located outside the housing 1. A one-way valve 14 is fixedly provided on the air inlet pipe 13. A handle 15 is fixedly provided on the outer wall of the connecting pipe 4 and located below the air inlet pipe 13.

[0024] Specifically in this embodiment, combined with Figure 1 , Figure 3 and Figure 4 As shown, a detachable pollen spraying pipe 16 is provided on the side of the connector 3 away from the shell 1. A protective cover 17 is provided at the end of the pollen spraying pipe 16. Preferably, the protective cover 17 is used to protect the stamens during pollination to prevent pollen from escaping to the stamens of different varieties next to it, thereby improving the purity of eggplant seed production. At the same time, the protective cover 17 can prevent damage to the stigma during pollination.

[0025] Specifically in this embodiment, combined with Figure 2 As shown, the housing 1, connector 3, storage box 8, retainer 9, pollen collection box 11, pollen spray pipe 16 and protective cover 17 are all made of disposable plastic transparent accessories, which facilitates observation of pollen in the device, facilitates cleaning of pollen remaining in the device, and facilitates replacement of accessories.

[0026] Working principle:

[0027] First, the pollen collection box 11 is removed from the retainer 9. The staff collects pollen into the pollen collection box 11. After the pollen collection box 11 has collected a certain amount of pollen, the opening of the pollen collection box 11 is facing upwards. The entire pollination device is then inverted to fix the pollen collection box 11 to the retainer 9. Next, the entire pollination device is inverted and reset. At this time, the opening of the pollen collection box 11 is facing downwards. By manually vibrating the pollen collection box 11, the pollen in the pollen collection box 11 falls into the storage box 8 through the filter screen 10. Impurities such as insects and broken petals mixed in with the pollen fall onto the filter screen 10.

[0028] Under normal conditions, pollen in the storage box 8 flows into the inner cavity 2 through the conveying pipe 5. When pollinating flowers, first, the protective cover 17 is brought close to the pistil. Then, the staff squeezes the airbag 12. Since the one-way valve 14 only enters from the outside to the inside, the sealing plate 7 rotates towards the side closer to the conveying pipe 5 and cooperates with the conveying pipe 5 the moment the airbag 12 is squeezed. The pollen flowing on the inner cavity 2 mixes with the air in the airbag 12 and is sprayed onto the pistil that needs pollination from the connector 3 and the pollen spray pipe 16. When the airbag 12 resets, the sealing plate 7 cooperates with the connecting pipe 4 by gravity and seals the inner end of the connecting pipe 4. Then, external gas is delivered into the connecting pipe 4 through the air inlet pipe 13. After the airbag 12 resets elastically, the air inlet pipe 13 stops delivering gas into the connecting pipe 4. After pollination is completed, the storage box 8, the retainer 9, the pollen collection box 11, and the pollen spray pipe 16 are removed for cleaning.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
