Description

Technical Field

[0001] This utility model relates to the field of germination technology, specifically a seed soaking and germination device for rice breeding. Background Technology

[0002] Rice breeding is an important means to improve rice yield and quality. In recent years, with the development of molecular biology technology, rice breeding has gradually shifted from traditional hybridization breeding to molecular breeding. Molecular breeding uses technologies such as molecular marker-assisted selection, gene editing and transgenics to more accurately and quickly cultivate new rice varieties with excellent traits.

[0003] In the process of rice breeding, in order to improve breeding efficiency, rice seeds are usually placed inside a corresponding germination box. This germination box can improve the germination rate and growth speed of the seeds. This device usually includes a seed soaking box, a chemical injection device, a heating device, and a drainage device. This equipment has multiple functions such as chemical soaking, automatic oxygenation, heating and germination, and drainage and drying. This germination box used for soaking and germinating rice seeds in the process of rice breeding can be called a rice breeding seed soaking and germination device.

[0004] However, when using this rice breeding soaking and germination device, it is necessary to spread the rice seeds one by one on multiple germination trays inside the device, which is a rather cumbersome operation; therefore, it does not meet the existing needs. In response, we have proposed a rice breeding soaking and germination device. Utility Model Content

[0005] The purpose of this utility model is to provide a rice breeding soaking and germination device to solve the problems mentioned in the background art, such as the need to spread rice seeds one by one on multiple germination trays inside the device when using this rice breeding soaking and germination device, which is a rather cumbersome operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rice seed soaking and germination device, comprising a seed soaking and germination box, a metal shell fixedly provided on one side of the outer surface of the seed soaking and germination box, a rice seed placement trough provided on the upper end face of the metal shell, the lower inner wall of the rice seed placement trough gradually rising from front to back, and a rice seed conveying trough provided at the lowest point of the lower inner wall of the rice seed placement trough, a rice seed conveying pipe provided inside the rice seed conveying trough, and an electric butterfly valve installed at the bottom end of the rice seed conveying pipe;

[0007] A stepper motor is fixedly installed inside a metal casing on one side of the rice seed conveying pipe. The output shaft of the stepper motor is connected to a lifting threaded rod through a coupling. An internal threaded sleeve matching its external thread is fitted on one side of the outer surface of the lifting threaded rod, and the surface of the internal threaded sleeve facing the rice seed conveying pipe is fixed to the rice seed conveying pipe.

[0008] The rice seed delivery pipe is located behind a germination chamber inside a seed soaking and germination box. The germination chamber is equipped with multiple placement platforms. Each placement platform has a germination tray on its upper surface, and a small vibration motor fixedly installed inside the placement platform is connected to the middle of the lower surface of the germination tray.

[0009] Preferably, the inner wall of the top end of the rice seed conveying pipe is an inclined surface, the outer surface of the rice seed conveying pipe is in contact with the inner wall of the rice seed conveying trough, and the rice seed conveying pipe and the rice seed conveying trough are slidably connected.

[0010] Preferably, a weight sensor is provided on both sides of the small vibration motor and fixed to the upper surface of the placement platform, and the upper surface of the weight sensor is in contact with the lower surface of the germination tray.

[0011] Preferably, the outer surface of the germination tray is in contact with the inner wall of the germination chamber, and the germination tray and the germination chamber are slidably connected.

[0012] Preferably, a transparent observation cabinet door is provided on one side of the metal casing, and the seed soaking and germination box is connected to the transparent observation cabinet door by a pivot.

[0013] Preferably, the top end of the lifting threaded rod is located inside the metal casing, and the lifting threaded rod located inside the metal casing is connected to the metal casing by a roller bearing.

[0014] Preferably, a metal cover plate is provided in front of the lifting threaded rod on the outer surface of the metal housing, and the metal housing and the metal cover plate are fixed together by screws.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model involves pouring rice seeds into a rice seed placement trough when the equipment is needed. The rice seeds poured into the trough will then flow along the lower inner wall of the trough into a seed conveying trough. The rice seeds entering the seed conveying trough will then enter a seed conveying pipe connected to the trough and fall into a germination tray. During this process, a small vibration motor in contact with the germination tray is simultaneously activated. The small vibration motor causes the germination tray to vibrate slightly, thus evenly spreading the rice seeds inside the tray. Once the germination tray is full of rice seeds, a stepper motor moves the seed conveying pipe upwards to the side of another germination tray, and the above operation is repeated. This technical solution automatically spreads rice seeds in multiple germination trays inside the soaking and germination box, thereby improving the automation level of the equipment.

[0017] 2. In this utility model, the outer surface of the germination tray is attached to the inner wall of the germination chamber. When the germination tray vibrates due to the small vibration motor, it will only move up and down because its outer surface is attached to the inner wall of the germination chamber. Under the action of gravity, the germination tray will always return to its original position. The above technical solution prevents the germination tray from being misaligned due to vibration.

[0023] 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.

[0024] The seed soaking and germination box 1 (model LFR), electric butterfly valve 6 (model D971X-16Q) and small vibration motor 14 (model YZSYZU) mentioned in this utility model can be obtained from the market or through private customization.

[0025] like Figure 1 and Figure 2As shown, one embodiment of this utility model is provided: a rice breeding soaking and germination device, including a soaking and germination box 1, a metal shell 2 fixedly provided on one side of the outer surface of the soaking and germination box 1, a rice seed placement trough 3 provided on the upper end surface of the metal shell 2, the lower inner wall of the rice seed placement trough 3 gradually rises from front to back, and a rice seed conveying trough 4 is provided at the lowest point of the lower inner wall of the rice seed placement trough 3, a rice seed conveying pipe 5 is provided inside the rice seed conveying trough 4, and an electric butterfly valve 6 is installed at the bottom end of the rice seed conveying pipe 5.

[0026] A stepper motor 7 is fixedly installed inside the metal casing 2 on one side of the rice seed conveying pipe 5. The output shaft of the stepper motor 7 is connected to a lifting threaded rod 8 through a coupling. An internal threaded sleeve 9 matching its external thread is fitted on one side of the outer surface of the lifting threaded rod 8, and the surface of the internal threaded sleeve 9 facing the rice seed conveying pipe 5 is fixed to the rice seed conveying pipe 5.

[0027] Behind the rice seed delivery pipe 5 is a germination chamber 10 located inside the seed soaking and germination box 1. The germination chamber 10 has multiple placement platforms 11 inside. Each placement platform 11 has a germination tray 12 placed on its upper surface, and a small vibration motor 14 fixedly installed inside the placement platform 11 is connected to the middle position of the lower surface of the germination tray 12.

[0028] As a preferred technical solution in this embodiment, such as Figure 3 and Figure 4As shown, a weight sensor 13 is fixed to the upper surface of the placement platform 11 on both sides of the small vibration motor 14, and the upper surface of the weight sensor 13 is in contact with the lower surface of the germination tray 12. When the equipment is to be used, rice seeds are poured into the rice seed placement trough 3, and then the electric butterfly valve 6 installed at the bottom end of the rice seed delivery pipe 5 is opened. The rice seeds poured into the rice seed placement trough 3 will enter the rice seed delivery trough 4 along the lower inner wall of the rice seed placement trough 3. The rice seeds entering the rice seed delivery trough 4 will enter the rice seed delivery pipe 5, which is connected to the inside of the rice seed delivery trough 4, and fall into the germination tray 12 located behind the rice seed delivery pipe 5. During this process, the small vibration motor 14 in contact with the germination tray 12 needs to be started at the same time. 4. This allows the germination tray 12 to vibrate slightly, thus evenly spreading the rice seeds that have fallen into the tray 12. Once the germination tray 12 is filled with rice seeds, the electric butterfly valve 6 is closed to stop the discharge of rice seeds. Then, the stepper motor 7 is started to drive the lifting threaded rod 8 connected to it to rotate. Through the transmission of the threaded structure, the inner threaded sleeve 9 fitted on the outer surface of the lifting threaded rod 8 will drive the rice seed conveying pipe 5 fixed thereto to move up and down together. At this time, the rice seed conveying pipe 5 is moved upward, and the bottom end of the rice seed conveying pipe 5 is moved to the side of another germination tray 12. Then, the electric butterfly valve 6 is opened again to continue discharging rice seeds and repeat the above operation. Through this embodiment, rice seeds can be automatically spread evenly in multiple germination trays 12 inside the soaking and germination box 1, thereby improving the automation level of the equipment.

[0029] The weight sensor 13 connected to the germination tray 12 can monitor the overall weight of the germination tray 12 in real time. When the inside of the germination tray 12 is filled with seeds and the rice seed delivery pipe 5 moves upward, the weight of the seeds inside the germination tray 12 can be determined by subtracting the weight of the germination tray 12 itself from the data detected at this time.

[0030] As a preferred technical solution in this embodiment, such as Figure 2 As shown, the inner wall of the top end of the rice seed conveying pipe 5 is an inclined surface 15. The outer surface of the rice seed conveying pipe 5 is in contact with the inner wall of the rice seed conveying trough 4, and the rice seed conveying pipe 5 and the rice seed conveying trough 4 are slidably connected. The inclined surface 15 can reduce the force required for the inclined surface 15 to move upward.

[0031] The outer surface of the germination tray 12 is in contact with the inner wall of the germination chamber 10, and the germination tray 12 and the germination chamber 10 are slidably connected. When the germination tray 12 vibrates due to the small vibration motor 14, since its outer surface is in contact with the inner wall of the germination chamber 10, it will only move up and down. Under the action of gravity, the germination tray 12 will always return to its original position. The above technical solution prevents the germination tray 12 from being misaligned due to vibration.

[0032] A transparent observation cabinet door 16 is provided on one side of the metal casing 2, and the seed soaking and germination box 1 is connected to the transparent observation cabinet door 16 by a pivot; the germination status of the seeds can be observed in real time through the transparent observation cabinet door 16.

[0033] The top end of the lifting threaded rod 8 is located inside the metal housing 2. The lifting threaded rod 8 located inside the metal housing 2 is connected to the metal housing 2 by a roller bearing. The roller bearing structure here increases the stability of the lifting threaded rod 8 and prevents it from tilting.

[0034] A metal cover plate is provided in front of the lifting threaded rod 8 on the outer surface of the metal housing 2, and the metal housing 2 and the metal cover plate are fixed together by screws; the metal cover plate can protect the internal structure of the metal housing 2, and when the internal structure of the metal housing 2 fails, the metal cover plate can be removed to repair its internal structure.

[0035] 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
