Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wheat seed drying devices, and in particular to a wheat seed drying device for breeding. Background Technology
[0002] Wheat is a common crop in our country, especially in the north where it is widely planted. In the process of wheat cultivation, sun-drying seeds is also a common practice. Generally, wheat seeds are sun-dried using a wheat seed drying device. Sun-drying breeding wheat is a key step in seed processing and storage. Its purpose is not only to reduce moisture content, but also to maintain seed viability, improve breeding efficiency, and ensure genetic purity.
[0003] The wheat seed drying device consists of a main frame and a breathable drying net. When in use, the seeds are evenly spread on the drying net and the wheat is turned over by a rake to achieve uniform drying. Finally, the seeds are collected after drying.
[0004] In practical applications, existing wheat seed drying devices rely heavily on frequent manual turning to overcome uneven drying and alleviate the aforementioned problems. However, this process is labor-intensive, resulting in low efficiency and significantly increasing the workload of operators. Furthermore, the excessive thickness of seed piles leads to poor ventilation and airflow obstruction within the device. This severely hinders the effective dissipation and exchange of heat and moisture within the seed pile, resulting in low heat and moisture exchange efficiency. Such conditions easily induce seed mold, significantly reducing germination rates and damaging seed viability due to localized heat accumulation. Utility Model Content
[0005] The purpose of this invention is to solve the problems of high labor intensity and long time consumption in manually turning wheat in the prior art and poor ventilation caused by excessive seed stacking thickness, and proposes a wheat seed drying device for breeding.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A wheat seed drying device for breeding includes a support frame and a drying box rotatably mounted on the support frame. The drying box mainly consists of a drying plate and a top cover, forming a closed space between the drying plate and the top cover. A first partition plate is fixedly installed inside the drying plate, and a second partition plate is fixedly installed inside the top cover. Both the first and second partition plates have crests and troughs, with the crests of the first and second partition plates staggered and the troughs forming a drying area. Ventilation sections are respectively provided on the first and second partition plates, and the ventilation sections are connected to the drying area. When natural wind enters the ventilation sections, the wheat seeds in the drying area come into contact with the natural wind.
[0008] To improve the ventilation effect of the equipment, preferably, the ventilation section includes ventilation channels opened on the drying board and the upper cover, and ventilation holes are opened on both the first partition plate and the second partition plate, and the ventilation holes are connected to the ventilation channels.
[0009] To facilitate airflow out of the equipment, the ventilation channel is further configured as unidirectional ventilation, with one end of the ventilation channel being a vent and the other end being closed with a drying board or upper cover. The vents of adjacent ventilation channels are arranged in opposite directions. When natural wind enters the ventilation channel, one of the ventilation channels will exhaust the natural wind to the drying area, while the adjacent ventilation channel will exhaust the natural wind through the vent.
[0010] To facilitate wheat feeding, preferably, a feeding plate is movably installed on the drying board corresponding to the drying area, and a pull-out handle is provided on the front of the feeding plate.
[0011] To prevent the upper cover from falling off when flipped, preferably, both the drying board and the upper cover are provided with fixing holes, and fixing pins are slidably installed in the fixing holes. When the drying board and the upper cover are combined, the fixing pins are inserted into the fixing holes to fix the drying board and the upper cover.
[0012] To prevent wheat from entering the ventilation holes, the diameter of the ventilation holes is in the range of 1.5-2.3 mm, and the ventilation holes are arranged at equal intervals on the first partition plate and the second partition plate.
[0013] Compared with the prior art, this utility model provides a wheat seed drying device for breeding, which has the following beneficial effects:
[0014] 1. The wheat seed drying device for breeding uses a first partition plate and a second partition plate in combination. When the drying box is turned over, the wheat seeds enter the drying area of the second partition plate from the drying area of the first partition plate, so that the wheat rolls naturally and achieves the effect of turning the wheat. This avoids the problems of increasing labor intensity and time consumption caused by using tools to turn the wheat.
[0015] 2. This wheat seed drying device for breeding uses ventilation channels and ventilation holes in combination. Natural wind enters the ventilation channels, circulates within the drying area, penetrates the wheat seeds, and is then discharged through adjacent ventilation channels. This effectively improves ventilation and prevents the wheat seeds from piling up too thickly, which would lead to low heat and moisture exchange efficiency and cause the seeds to mold.
[0016] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model uses the first and second partition plates in conjunction with the drying box. After rotating the drying box, the wheat seeds can fall into the drying area of the second partition plate, so that the wheat seeds can be turned over. At the same time, the ventilation part can improve the ventilation effect in the drying area. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example
[0024] Reference Figures 1-4 A wheat seed drying device for breeding includes a support frame 1 and a drying box rotatably mounted on the support frame 1. The drying box mainly consists of a drying plate 2 and an upper cover 3, with a rotating shaft fixedly installed in the middle of the end face of the drying plate 2. A rotation damper is provided at the connection between the rotating shaft and the support frame 1. In this application, the rotation damper is a Peer PR-T036 model damper. A closed space is formed between the drying plate 2 and the upper cover 3. A first partition plate 4 is fixedly installed inside the drying plate 2, and a second partition plate 5 is fixedly installed inside the upper cover 3. In this application, the drying plate 2, the upper cover 3, and the first partition plate 4 form a closed space. Both the first partition plate 4 and the second partition plate 5 are made of acrylic sheets. Both the first partition plate 4 and the second partition plate 5 have crests and troughs. The crests of the first partition plate 4 and the second partition plate 5 are staggered, and the troughs of the first partition plate 4 and the second partition plate 5 form a drying area. Ventilation sections are provided on the first partition plate 4 and the second partition plate 5 respectively. The ventilation sections are connected to the drying area. When natural wind enters the ventilation section, the wheat seeds in the drying area come into contact with the natural wind, thereby effectively improving the ventilation effect in the drying area and effectively avoiding the problem of premature germination of seeds due to low heat and moisture exchange efficiency.
[0025] Specifically, by using the first partition plate 4 and the second partition plate 5 together, when the drying box is turned over, the wheat seeds move from the drying area of the first partition plate 4 into the drying area of the second partition plate 5, causing the wheat to roll naturally and thus achieving the effect of turning the wheat over. This avoids the problems of increasing labor intensity and time consumption caused by using tools to turn the wheat over.
[0026] The ventilation section includes ventilation channels 7 formed on the drying board 2 and the upper cover 3. Ventilation holes 6 are evenly arranged on the first partition plate 4 and the second partition plate 5, and the ventilation holes 6 are connected to the ventilation channels 7. The ventilation channels 7 are configured for unidirectional ventilation. One end of the ventilation channel 7 is set as a vent, and the other end is closed with the drying board 2 or the upper cover 3. The vents of adjacent ventilation channels 7 are set in opposite directions. When natural wind enters the ventilation channels 7, one of the ventilation channels 7 exhausts the natural wind to the drying area, while the adjacent ventilation channels 7 exhaust the natural wind through the vent. By setting the vents of adjacent ventilation channels 7 in opposite directions, natural wind can enter from opposite sides of the drying board 2, thereby improving the air intake effect of this application. At the same time, the natural wind enters the ventilation channels 7 and is forced to circulate, and comes into contact with the wheat seeds through the ventilation holes 6, effectively improving the heat and moisture exchange efficiency and effectively avoiding the problem of seed mold or premature germination.
[0027] Specifically, by using ventilation channels 7 and ventilation holes 6 together, natural wind enters the ventilation channels 7, circulates within the drying area and penetrates the wheat seeds, and is then discharged through adjacent ventilation channels 7, effectively improving ventilation and preventing the wheat seeds from piling up too thickly, which would lead to low heat and moisture exchange efficiency and cause the seeds to mold.
[0028] The drying board 2 is movably installed with a feeding board 8 corresponding to the drying area, and the front of the feeding board 8 is provided with a pull handle. After the wheat seeds have been dried, the feeding board 8 is separated from the drying board 2 by pulling the pull handle. Then, the drying board 2 is rotated to tilt it, and the wheat seeds slide out of the drying area due to gravity, which makes it convenient to collect the wheat seeds.
[0029] Both the drying board 2 and the upper cover 3 are provided with fixing holes, and fixing pins are slidably installed in the fixing holes. When the drying board 2 and the upper cover 3 are combined, the fixing pins are inserted into the fixing holes to fix the drying board 2 and the upper cover 3. The fixing pins are used to fix the drying board 2 and the upper cover 3, thereby effectively preventing the upper cover 3 from accidentally falling off when the drying board 2 is rotated.
[0030] The diameter of the ventilation hole 6 ranges from 1.5 to 2.3 mm. The preferred diameter of the ventilation hole 6 in this application is 2.2 mm. Since wheat is elliptical, the short axis of normal wheat seeds is generally 2.4-4 mm, and most are concentrated in 3-3.5 mm. By setting the ventilation hole 6 to a diameter of 2.2 mm, the problem of wheat falling into the ventilation hole 6 and getting stuck or leaking out of the device can be effectively avoided.
[0031] In this invention, wheat seeds are first poured into the drying board 2 and spread evenly in the drying area. Then, the upper cover 3 is installed on top of the drying board 2 and fixed to the drying board 2 with fixing pins. The wheat seeds are then placed in the drying area. When natural wind enters from the ventilation channel 7, the natural wind is discharged through the ventilation hole 6 and penetrates the wheat seeds in the drying area. At this time, the heat and moisture generated during the drying of the wheat seeds are discharged through the adjacent ventilation channel 7 and the ventilation hole 6. This effectively avoids the problem of low heat and moisture exchange efficiency due to excessive accumulation of wheat, which can lead to mold or premature germination of wheat.
[0032] Meanwhile, when it is necessary to turn the wheat seeds, simply rotate the drying board 2 to exchange positions with the upper cover 3. At this time, the wheat will fall into the drying area of the upper cover 3 due to gravity. Since the second partition 5 has crests, it divides the wheat in the drying area of the first partition 4, so that the wheat seeds can be evenly distributed into the drying area of the second partition 5. The wheat automatically turns over as it rolls during the fall, effectively avoiding the problem of increased labor and time caused by touching tools to turn the wheat.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
