Description

Technical Field

[0001] This utility model belongs to the field of crop breeding technology, specifically relating to a drying device for breeding new crop varieties. Background Technology

[0002] Seeds are the reproductive bodies unique to gymnosperms and angiosperms. They are formed from ovules through pollination and fertilization. The moisture content of seeds directly affects their storage life and germination rate. Seed germination rate is one of the four most important basic quality indicators of seeds (purity, cleanliness, germination rate, and moisture). Taking hybrid rice seeds as an example, seeds with a germination rate of less than 80% are considered unqualified. Newly harvested seeds, even those harvested at full maturity, contain a considerable amount of moisture. Therefore, seeds must undergo drying treatment before breeding.

[0003] For example, CN 221147122 U discloses a seed drying device that effectively solves the problem that existing seed drying devices cannot dry seeds evenly and thus reduce drying efficiency. The device includes a housing with an inlet pipe and an outlet pipe fixedly connected to its top and bottom, respectively. A first hollow cylinder and a second hollow cylinder are fixedly connected to the inner bottom wall of the housing. The second hollow cylinder is located inside the first hollow cylinder. A lower hollow funnel is fixedly connected to the top of the first hollow cylinder, and an upper hollow funnel is fixedly connected to the top of the lower hollow funnel. A lifting component is located in the middle of the second hollow cylinder. By using the housing, first hollow cylinder, second hollow cylinder, lower hollow funnel, upper hollow funnel, annular plate, hollow pipe, hot air blower, and lifting component in combination, not only can seeds be dried evenly, but the seed drying efficiency is also improved.

[0004] In the actual use of the above cases, due to the different plumpness of the seeds, the drying rate is also different. After some smaller seeds are dried, the larger seeds are not completely dried, which makes the device have certain defects. Therefore, this utility model provides a drying device for the breeding of new crop varieties. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for the breeding of new crop varieties, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying device for breeding new crop varieties, comprising a drying tank, the top of the drying tank being provided with a top cover, the top of the top cover being provided with a feed pipe, the bottom of the drying tank being provided with a conical part, the bottom end of the conical part being provided with a discharge pipe, and the interior of the drying tank being provided with a sieve frame, the sieve frame being an inverted cone.

[0007] In a preferred embodiment, a hot air ring is fixedly connected inside the inner cavity of the drying tank. The hot air ring is located below the sieve frame, and the exhaust port of the hot air ring is located below the hot air ring.

[0008] In a preferred embodiment, the screen frame is provided with a plurality of conical screens inside, and the aperture values ​​of the plurality of conical screens increase sequentially from top to bottom, and a ring frame is provided at the connection of every two conical screens.

[0009] In a preferred embodiment, a connecting shaft is fixedly connected to the center of the bottom of the inner cavity of the screen frame, and a guide plate is fixedly connected to the top of the connecting shaft. The guide plate is arc-shaped, and the edge of the guide plate is located directly above the top edge of the screen frame.

[0010] In a preferred embodiment, a support ring is fixedly connected to the inner wall of the drying tank. The top of the support ring fits against the bottom of the edge of the sieve frame, and the sieve frame has a plurality of annularly spaced elastic members on the side facing the support ring.

[0011] In a preferred embodiment, each of the elastic elements includes two "S"-shaped elastic plates fixedly connected to the screen frame. The bottom of the two elastic plates is fixedly connected to a connecting plate that abuts against the support ring. The top of the support ring is provided with a connecting groove that matches the connecting plate.

[0012] In a preferred embodiment, the drying tank is provided with a support frame on its exterior.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This drying device for breeding new crop varieties uses an inverted conical sieve frame with multiple conical screens of gradually increasing aperture inside the frame. This allows for graded drying of seeds of different sizes. Smaller seeds fall through the upper small-aperture screen to the lower layer for further drying, while larger seeds continue to dry on the upper screen until they reach the appropriate degree of dryness before falling through the larger aperture. This design avoids differences in drying rate due to different seed sizes, making the entire drying process more uniform and efficient.

[0015] This drying device for breeding new crop varieties uses an arc-shaped guide plate fixed at the top of the connecting shaft, with its edge located directly above the top edge of the sieve frame. This effectively guides undried seeds to fall to the edge of the sieve frame for gradual drying. When the seeds fall to the top of the arc-shaped guide plate, the elastic plate deforms under force, causing the entire sieve frame to vibrate slightly, thereby improving the sieving efficiency.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3This utility model provides a drying device for breeding new crop varieties, including a drying tank 1. The top of the drying tank 1 is provided with a top cover 3, and the top of the top cover 3 is provided with a feed pipe 4. The bottom of the drying tank 1 is provided with a conical part, and the bottom end of the conical part is provided with a discharge pipe 5. The drying tank 1 is provided with a sieve frame 7, which is an inverted cone. A hot air ring 6 is fixedly connected to the inside of the drying tank 1. The hot air ring 6 is located below the sieve frame 7, and the exhaust port of the hot air ring 6 is located below the hot air ring 6. The sieve frame 7 is provided with multiple conical screens 701 inside, and the aperture value of the multiple conical screens 701 increases from top to bottom. A ring frame 702 is provided at the connection of every two conical screens 701. A support frame 2 is provided on the outside of the drying tank 1. Seeds will naturally fall on the top of the sieve frame 7. The hot air is activated. In ring 6, hot air is evenly discharged from the exhaust port of hot air ring 6, forming an upward hot air flow. The hot air passes through sieve frame 7 and conical sieve 701, which evenly heats and dries the seeds. The seeds gradually dry under the action of hot air and begin to fall due to gravity. Since there are multiple conical sieves 701 with increasing aperture from top to bottom inside sieve frame 7, smaller seeds will fall to the lower layer through the upper small aperture sieve earlier for further drying, while larger seeds will continue to dry on the upper sieve. This graded sieving and drying method ensures that each seed receives an appropriate drying time. After sufficient drying and sieving, the seeds will fall from the bottom of sieve frame 7 to the conical part at the bottom of drying tank 1. Finally, the dried seeds are discharged from the device through the discharge pipe 5 at the bottom of the conical part.

[0023] The grading and screening method avoids mixing and drying seeds of different sizes, ensuring that each seed receives an appropriate drying time, thereby protecting the quality of the seeds.

[0024] In this embodiment, a connecting shaft 8 is fixedly connected to the center of the bottom of the inner cavity of the sieve frame 7, and a guide plate 9 is fixedly connected to the top of the connecting shaft 8. The guide plate 9 is arc-shaped, and the edge of the guide plate 9 is located directly above the top edge of the sieve frame 7. A support ring 101 is fixedly connected to the inner wall of the drying tank 1. The top of the support ring 101 fits against the bottom edge of the sieve frame 7, and the sieve frame 7 has a plurality of annularly spaced elastic elements on the side facing the support ring 101. Each elastic element includes two "S"-shaped elastic plates 10 fixedly connected to the sieve frame 7, and the bottom of the two elastic plates 10 is fixedly connected to the support ring 7. The supporting ring 101 abuts against the connecting plate 11. The top of the supporting ring 101 is provided with a connecting groove that matches the connecting plate 11. After the seeds enter the drying tank 1 through the feed pipe 4, they first fall on the top of the guide plate 9. The edge of the guide plate 9 is located directly above the top edge of the sieve frame 7. When the seeds fall to the guide plate 9, they will be guided to slide along the arc of the guide plate 9 to the edge of the sieve frame 7, and then fall into the next layer of conical screen 701 for further drying and screening. When the seeds fall to the top of the guide plate 9, the elastic plate 10 causes the sieve frame 7 to vibrate to a certain extent, thereby improving the screening effect of the seeds.

[0025] The design of the guide plate 9 allows the seeds to be distributed more evenly on the sieve frame 7 and guides the seeds to slide down the edge of the sieve frame 7 along the arc of the guide plate 9, thereby improving the drying efficiency. The elastic element consists of an "S"-shaped elastic plate 10 and a connecting plate 11. The design is simple and easy to manufacture. Vibration-assisted sieving further improves the sieving efficiency, making the entire drying process more efficient.

[0026] The working principle and usage process of this utility model are as follows: First, the seeds enter the drying tank 1 through the feed pipe 4 and fall onto the top of the guide plate 9. The edge of the guide plate 9 is located directly above the top edge of the sieve frame 7. When the seeds fall onto the guide plate 9, they are guided to slide along the arc of the guide plate 9 towards the edge of the sieve frame 7, and then fall into the next layer of conical sieve 701 for further drying and sieving. When the seeds fall to the top of the guide plate 9, the elastic plate 10 causes the sieve frame 7 to vibrate to a certain extent, thereby improving the sieving effect of the seeds. The seeds will naturally fall onto the top of the sieve frame 7. The hot air ring 6 is activated, and hot air is evenly discharged from the exhaust port of the hot air ring 6, forming an upward hot airflow. The hot air passes through the sieve. The frame 7 and the conical screen 701 heat and dry the seeds evenly. The seeds gradually dry under the action of hot air and begin to fall due to gravity. Since the frame 7 has multiple conical screens 701 with increasing apertures from top to bottom, smaller seeds will fall to the lower layer through the upper small aperture screen for further drying, while larger seeds will continue to dry on the upper screen. This graded sieving and drying method ensures that each seed receives an appropriate drying time. After thorough drying and sieving, the seeds will fall from the bottom of the frame 7 to the conical part at the bottom of the drying tank 1. Finally, the dried seeds are discharged through the discharge pipe 5 at the bottom of the conical part.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
