[0002] Rice seeds are the seeds of rice. Cultivating rice seedlings is the first and key step in planting rice. After the rice seedlings are cultivated, they are transplanted by transplanting. There are two basic conditions for grain germination. The first is that the seeds themselves have good germination ability, with healthy embryos and strong vitality. The second is that there are external conditions suitable for grain germination, referred to as external factors, such as environmental temperature (suitable temperature 22-28℃), oxygen concentration, light and humidity.
[0003] Existing breeding devices are usually multi-layered, with seeds to be germinated laid on each layer, and liquid is sprayed on the seeds from the top, and the temperature and humidity inside the device are regulated to achieve the automatic breeding and germination function of rice. However, the device usually does not screen the rice seeds when in use, so that some unfilled rice seeds, empty shells, necrotic rice seeds and high-quality rice seeds are mixed together, and a small area of rot and mold is prone to occur during cultivation, which affects the growth of high-quality rice seeds and reduces the overall germination rate.

[0031] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.
[0032] It should be noted that when an element is referred to as being "fixedly provided on" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used herein in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0034] Please refer to Figures 1 to 8 , which shows a germination accelerating device for rice breeding experiments according to an embodiment of the present invention, including a box body 10, a breeding component 20 arranged in the box body 10, an environmental adjustment component 30 arranged above the breeding component 20, and a seed screening component 40 arranged below the breeding component 20. A breeding liquid is provided at the bottom of the box body 10. In the initial state, the breeding component 20 is located above the liquid level of the breeding liquid;
[0035] The breeding component 20 includes a breeding frame 21 and a first driving component 22 arranged on the side of the breeding frame 21. The first driving component 22 is used to drive the breeding frame 21 to move up and down. The breeding frame 21 is used to place seeds to be germinated. Filter holes 23 are provided at the bottom of the breeding frame 21;
[0036] The seed screening assembly 40 includes a longitudinally arranged filter screen 41 and a second driving member 42 disposed on one side of the filter screen 41. The second driving member 42 is used to drive the filter screen 41 to move from one side of the box body 10 to the other side, and a bottom portion of the filter screen 41 is placed in the breeding liquid.
[0037] A collection box 50 is provided on a side of the box body 10 away from the filter screen 41. An opening 51 is provided on a top side of the collection box 50 and communicates with the box body 10. A sloping plate 52 extends downward from the bottom of the opening 51, and a bottom portion of the sloping plate 52 is placed in the breeding liquid.
[0038] It can be understood that by providing the box body 10 and arranging the breeding liquid at the bottom of the box body 10, rice seeds can be soaked in the breeding liquid. Then, by providing the breeding assembly 20, the rice seeds are placed in the breeding frame 21 and move up and down with the first driving member 22, and thus are soaked in the breeding liquid, making the rice seeds soaked in the breeding liquid as a whole. When there are underfilled rice seeds, empty husks, and necrotic rice seeds in the rice seeds, these non-quality seeds will float on the surface of the breeding liquid under the action of buoyancy. Then, through the seed screening assembly 40 in the box body 10, the second driving member 42 drives the filter screen 41 to move left and right in the box body 10, thereby driving the unqualified seeds floating on the surface of the breeding liquid to the side of the box body 10 where the collection box 50 is provided. The unqualified seeds will slide into the collection box along the sloping plate 52 under the action of the filter screen 41, and the filter screen 41 will finally move to the opening 51 of the collection box, preventing the impact force of the unqualified seeds from being insufficient and staying on the sloping plate 52, so as to ensure that all the unqualified seeds are screened out of the box body 10. When the seed soaking is completed, the breeding frame 21 drives the seeds to move upward to the initial position, and the breeding liquid flows out from the filter holes 23 in the breeding frame 21, thereby completing the steps of seed soaking and screening of unqualified seeds. Then, the environmental adjustment assembly 30 adjusts the environment in the box body 10 to ensure the growth condition and germination rate of the seeds. Therefore, the present invention solves the problem that when using the breeding device in the prior art to breed and germinate rice seeds, the overall germination rate of the rice seeds is relatively low and the growth condition is relatively poor.
[0039] It should be noted that placing the bottom part of the filter sieve 41 in the breeding liquid instead of flush with the breeding liquid is to ensure that when the filter sieve 41 drives to screen out unqualified seeds in the breeding liquid, it can avoid some seeds from colliding and squeezing with each other, resulting in a small number of seeds moving to the bottom of the breeding liquid surface under the squeezing force and thus avoiding the filter sieve 41, which may lead to incomplete filtration by the filter sieve 41. In addition, when the filter sieve 41 moves in the breeding liquid, it will agitate the breeding liquid surface, which may also cause some unqualified seeds to float up and down at the breeding liquid surface. Therefore, the bottom of the filter sieve 41 needs to be partially placed in the breeding liquid. In addition, the inclined plate 52 at the collection box 50 is partially placed in the breeding liquid, so that the seeds at the liquid surface can move along the inclined plate 52 from the liquid surface. By setting the inclined plate 52 instead of directly setting the opening 51 flush with the liquid surface, it can avoid the breeding liquid from entering the collection box 50, resulting in a decrease in the liquid surface, affecting the effect of subsequent seeds moving into the collection box 50, and increasing the consumption of the breeding liquid, affecting the subsequent breeding effect. In addition, it should be noted that the bottom of the filter sieve 41 has a certain elasticity. When the filter sieve 41 moves to the opening 51 and interferes with the inclined side, due to the elasticity of the bottom of the filter sieve 41, the filter sieve 41 can be prevented from being damaged.
[0040] Specifically, the first driving component 22 includes a driving lifting rod 221, a top plate 222 connected to the driving lifting rod 221, a bottom plate 223 arranged below the top plate 222, and a first vertical rod 224 connecting the top plate 222 and the bottom plate 223. The bottom plate 223 is connected to the breeding frame 21. In specific implementation, the two first vertical rods 224 are arranged in parallel on both sides of the top plate 222, so that both ends of the top plate 222 and the bottom plate 223 are connected to each other, and the driving lifting rod 221 is connected to the middle of the top plate 222. There is a through hole at the bottom of the box body 10, so that the first vertical rod 224 can extend into the box body 10 through the through hole to be connected to the bottom plate 223. By driving the lifting rod 221 to drive the top plate 222 to move up and down, the bottom plate 223 and the breeding frame 21 are driven to move up and down, so as to realize the function of driving the seeds in the breeding liquid in the box body 10 by the breeding frame 21 for soaking and resetting. In addition, the driving lifting rod 221 can adopt an electric telescopic rod, a hydraulic telescopic rod or other structures or devices that can achieve this function.
[0041] In addition, a sliding rod 24 is provided on one side of the breeding frame 21 close to the first driving member 22, and a roller 25 is provided on the other side. A spring 26 is sleeved on the sliding rod 24. A through hole 225 adapted to the sliding rod 24 is provided on the bottom plate 223. A corrugated plate 11 adapted to the roller 25 is provided on the side surface of the bottom of the box body 10. Sliding grooves 211 are provided on both sides of the breeding frame 21. Slide bars 226 adapted to the sliding grooves 211 extend outward from both sides of the bottom plate 223. The breeding frame 21 moves downward under the action of the first driving member 22, so that the roller 25 is squeezed against the corrugated plate 11, and the spring 26 on the other side is squeezed, thereby driving the box body 10 to move back and forth along the sliding grooves 211. In a specific implementation, the breeding frame 21 moves downward under the action of the first driving member 22, so that the roller 25 is squeezed against the peak of the corrugated plate 11, thereby pushing the breeding frame 21 to move away from the corrugated plate 11, and then the spring 26 is squeezed and deformed. When the breeding frame 21 moves to the height of the trough of the corrugated plate 11, there is no squeezing action of the corrugated plate 11 outside the roller 25. Then, under the action of the elastic restoring force of the spring 26, the breeding frame 21 is driven to approach the corrugated plate 11, thereby realizing the reciprocating movement of the breeding frame 21. And a certain collision force will be generated between the roller 25 and the corrugated plate 11, so that the seeds in the breeding frame 21 are in a shaking and vibrating state, thereby vibrating the unqualified seeds accumulated and squeezed under the qualified seeds to the surface, and then making the unqualified seeds float on the surface of the breeding liquid, further enhancing the screening effect and avoiding the situation that the growth of qualified seeds is affected by the rotting of unqualified seeds.
[0042] Specifically, the germination accelerating device for rice breeding experiments further includes a material turning component 60. The material turning component 60 includes a material turning rod 61 disposed in the breeding frame 21, a first longitudinal rod 62 disposed above the material turning rod 61, a second vertical rod 63 connecting the first longitudinal rod 62 and the material turning rod 61, a driving rod 64 disposed above the first longitudinal rod 62, and a connecting rod 65 connecting the driving rod 64 and the first longitudinal rod 62. The bottom of the material turning rod 61 is flat and the two sides are inclined planes. The cross-sectional area of the material turning rod 61 gradually decreases from the bottom to the top. The driving rod 64 is used to connect the second driving component 42, and the second driving component 42 drives the material turning rod 61 to move left and right in the breeding frame 21. In specific implementation, by setting the material turning component 60, when the seeds are soaked or after soaking and then undergoing breeding, the seeds in the breeding frame 21 can be turned, ensuring that each seed is evenly soaked during soaking, and turning the unqualified seeds piled at the bottom to the surface, making them automatically float upward. After soaking, turning the seeds enables the bottom seeds to be turned to the surface, avoiding a large difference in the contact time between the bottom and top seeds with the outside world, and thus avoiding a large difference in humidity and dryness between the two, which may affect the overall breeding and germination effect. For example, the good germination effect on the outside is due to dryness, while the poor germination effect at the bottom is due to high humidity. In addition, in specific implementation, by setting the bottom of the material turning rod 61 to be flat and the two sides to be inclined planes, and making the bottom of the material turning rod 61 flush with the bottom of the breeding frame 21, the seeds move along the inclined planes from above the material turning rod 61 for material turning.
[0043] Further, the second driving component 42 includes a driving motor 421, a screw rod 422 connected to the driving motor 421, and a screw sleeve 423 disposed on the screw rod 422. The side of the screw sleeve 423 is connected to the filter screen 41. The box body 10 is provided with a first transverse groove 12, and the first transverse groove 12 is used to avoid the screw sleeve 423, so that the screw sleeve 423 drives the filter screen 41 to move in the box body 10. In specific implementation, the driving motor 421 drives the screw rod 422 to rotate, the screw rod 422 drives the screw sleeve 423 to move back and forth along the screw rod 422, and then the screw sleeve 423 drives the filter screen 41 to move in the box body 10, enabling the filter screen 41 to filter out unqualified seeds on the breeding liquid surface.
[0044] Additionally, a dial plate 424 is provided at the top of the screw sleeve 423. One end of the driving rod 64 extends out of the box body 10 and is sleeved on a dial block 66. A second longitudinal rod 67 is provided above the dial block 66. A second horizontal groove 13 and a third horizontal groove 14 are provided on the box body 10. The second horizontal groove 13 penetrates through one side wall of the box body 10. The connection part of the dial block 66 and the driving rod 64 is placed in the second horizontal groove 13. The second longitudinal rod 67 is placed in the third horizontal groove 14. Symmetrically arranged inclined grooves 15 are respectively provided above both sides of the third horizontal groove 14. A triangular block 16 is formed between the inclined groove 15 and the third horizontal groove 14. An inclined plate 17 rotatably connected to the triangular block 16 is provided on the side of the triangular block 16 close to the second horizontal groove 13. The bottom of the inclined plate 17 abuts against the bottom of the second horizontal groove 13. Vertical grooves 18 are provided on both sides of the second horizontal groove 13. The two vertical grooves 18 are respectively communicated with the second horizontal groove 13, the third horizontal groove 14 and the inclined groove 15 on the same side. During specific implementation, the driving motor 421 drives the screw 422 to rotate. The screw sleeve 423 moves on the screw 422 and drives the dial plate 424 to move. The dial plate 424 moves towards the direction close to the dial block 66 and squeezes and pushes the dial block 66 to move along the second horizontal direction. The dial block 66 drives the second longitudinal rod 67 to move along the third horizontal groove 14. When moving to the intersection of the third horizontal groove 14 and the inclined groove 15, since the second longitudinal rod 67 is inside the inclined plate 17 at this time, it squeezes the inside of the inclined plate 17, causing the inclined plate 17 to flip, and then continues to move until the second longitudinal rod 67 moves to the intersection of the third horizontal groove 14 and the inclined groove 15 on the other side. At this time, the second longitudinal rod 67 is outside the inclined plate 17 at this place, and the inclined plate 17 abuts against the bottom of the third horizontal groove 14. Then the second longitudinal rod 67 will move along the inclined plate 17 towards the inclined groove 15 direction and drive the dial block 66 to move relative to the second longitudinal rod 67 until the second longitudinal rod 67 moves into the vertical groove 18. At this time, the dial block 66 moves up to a certain height, and the height of the bottom of the dial block 66 exceeds that of the dial plate 424. The dial plate 424 will continue to move forward and pass under the dial block 66. Due to the lack of the acting force of the dial plate 424, the dial block 66 will reset under the action of gravity, and then drive the second longitudinal rod 67 to align with the third horizontal groove 14. At this time, the dial plate 424 is on the other side of the dial block 66, and the screw sleeve 423 moves to the bottom of the screw 422. Then, through the reversal of the driving motor 421, the screw sleeve 423 moves back. Thus, the effect that the single driving motor 421 drives the material turning assembly 60 and the seed filtering assembly to act simultaneously is achieved. In addition, the connecting rod 65 is a telescopic rod, and the dial block 66 is in a Z shape, so that the filter screen 41 and the connecting rod 65 are arranged in a staggered manner. It should be noted that when the breeding frame 21 moves downward to soak the seeds, by setting the connecting rod 65 as a telescopic rod and the dial block 66 in a Z shape, when the seeds are soaked, the material turning assembly 60 and the screening and filtering assembly can operate simultaneously, and the screening and filtering and the connecting rod 65 will not interfere. After the seeds are soaked, the breeding frame 21 resets, and the material turning assembly 60 can also turn the seeds, so that each seed receives the same drying effect or wetting effect.At this time, the screening component also operates to prevent the situation where some unqualified seeds lean against the inner edge of the box body 10 under the shaking action and are not collected into the collection box 50.
[0045] Specifically, a sliding door 19 is provided on the box body 10, and the sliding door 19 is located between the first horizontal groove 12 and the second horizontal groove 13. In specific implementation, the sliding door 19 can be made of a transparent material, so that the breeding condition inside the box body 10 can be directly observed in real time. In addition, by using the sliding door 19, the box body 10 has a relatively large inlet and outlet with the outside world. Furthermore, the breeding frame 21 can be pulled out of the box body 10 to lay seeds in the breeding frame 21, improving the feeding efficiency.
[0046] In addition, the environment adjustment component 30 includes a liquid outlet pipe 31 provided at the inner top of the box body 10, a heating element 32 provided on the liquid outlet pipe 31, a liquid inlet pipe 33 communicated with the liquid outlet pipe 31 and located outside the box body 10, and a sensing component 34 provided on the side of the box body 10. The sensing component 34 is used to monitor the humidity and temperature inside the box body 10. In specific implementation, the temperature and humidity inside the box body 10 are monitored by the sensing component 34, and then heating is carried out through the heating element 32 and the liquid outlet pipe 31, and liquid is sprayed to adjust the environment inside the box body 10 to ensure the normal growth and germination of seeds.
[0047] Furthermore, multiple liquid outlet pipes 31 are evenly distributed inside the box body 10, and a plurality of nozzles 35 are provided on the liquid outlet pipes 31. The heating element 32 is distributed in a serpentine shape inside the box body 10 and surrounds the liquid inlet pipe 33. By providing a plurality of nozzles 35, liquid is evenly sprayed inside the breeding frame 21 to make the humidity condition inside the box body 10 evenly distributed. In addition, by surrounding the liquid inlet pipe 33 with the heating element 32, the heating element 32 will heat the liquid in the liquid inlet pipe 33 to a certain extent. Thus, while the liquid adjusts the humidity, it will also adjust the temperature to a certain extent, avoiding the situation where the temperature inside the box body 10 is adjusted by the heat radiation of a single heating element 32, resulting in low temperature adjustment efficiency and uneven temperature distribution.
[0048] In summary, by providing the box body 10 and arranging the breeding liquid at the bottom of the box body 10, the rice seeds can be soaked in the breeding liquid. Then, by providing the breeding assembly 20, the rice seeds are placed in the breeding frame 21 and move up and down with the first driving component 22, and thus are soaked in the breeding liquid, so that the whole rice seeds are soaked in the breeding liquid. When there are underfilled rice seed grains, empty husks, and necrotic rice seeds in the rice seeds, these non-high-quality seeds will float on the surface of the breeding liquid under the action of buoyancy. Then, through the seed screening assembly 40 in the box body 10, the second driving component 42 drives the filter screen 41 to move left and right in the box body 10, thereby driving the unqualified seeds floating on the surface of the breeding liquid to the side of the box body 10 provided with the collection box 50. The unqualified seeds will slide into the collection box along the inclined plate 52 under the action of the filter screen 41, and finally the filter screen 41 will move to the opening 51 of the collection box, preventing the unqualified seeds from having insufficient impact force and staying on the inclined plate 52, so as to ensure that all the unqualified seeds are screened out of the box body 10. When the seed soaking is completed, the breeding frame 21 drives the seeds to move upward to the initial position, and the breeding liquid flows out from the filter holes 23 in the breeding frame 21, thus completing the steps of seed soaking and screening of unqualified seeds. Then, the environmental adjustment assembly 30 adjusts the environment in the box body 10 to ensure the growth condition and germination rate of the seeds. Therefore, the present invention solves the problem that when using the breeding device in the prior art to breed and germinate rice seeds, the overall germination rate of the rice seeds is relatively low and the growth condition is relatively poor.
