Description

Technical Field

[0001] The invention relates to the technical field of wheat seedling cultivation, in particular to a wheat seedling cultivation device and a cultivation method. Background Art

[0002] Wheat breeding is the experimental stage test of agricultural wheat planting. Specifically, in the process of agricultural wheat planting and production, it is necessary to cultivate excellent wheat varieties on a small scale in the laboratory. Cultivation mainly includes seedling cultivation. After the seedlings are cultivated to a certain seedling height, the seedlings need to be planted in the experimental field.

[0003] In the prior art, a Chinese patent with publication number "CN218218542U" discloses a wheat seedling cultivation device, which uses multiple nozzles on a sprinkler plate to spray water onto the wheat seedlings, thereby replenishing water to the wheat seedlings during the cultivation process. At the same time, a ring-shaped material plate is used to enable the cultivated wheat to rotate flexibly. Therefore, during the cultivation process, it is possible to ensure that the wheat seedlings can continuously adjust their angles and fully contact the spray water, thereby solving the problem that the existing wheat seedlings cannot evenly contact the spray water.

[0015] A method for cultivating wheat seedlings, based on the above-mentioned device for cultivating wheat seedlings, comprises the following steps: S1. Place the seedling cups containing wheat seedlings on the mounting plate and arrange them in a ring shape. Start a water pump to pass the water in the water tank into the diversion pipe through the drainage pipe. The water in the diversion pipe will be discharged into the drainage board through the outlet pipe, the telescopic hose and the connecting pipe. The water in the drainage board will be sprayed on the seedling cups containing wheat seedlings through multiple spray heads. S2, then start the motor to use the drive shaft to drive the drive plate and the mounting ring to rotate. When the track column slides in one of the downward pressure tracks, the track column will drive the reciprocating rod on the L-shaped plate to move downward through the drive rod and the linkage shaft. At the same time, the positioning arc rod on the mounting ring cooperates with the positioning grooves on the two circular plates to drive the mounting plate to move downward through the support frame plate. When the track column continues to rotate, it will slide in one of the rotating tracks. At this time, the reciprocating rod will drive the mounting plate on the support frame plate to move upward, and the driving column on the mounting ring will cooperate with one of the arc grooves on the connecting column. Finally, the reciprocating rod will drive the mounting plate on the support frame plate to rotate through the limit of the rotating block and the side strip. The height of the drainage plate on the mounting plate can be adjusted by lowering and rotating the mounting plate to ensure that the drainage plate is in a suitable position, which can more effectively manage the spraying of water. S3, when the track column continues to slide and contacts another downward pressure track, the subsequent steps are as described in S2, and the mounting plate is driven to descend through the support frame plate. At the same time, when the track column slides and contacts another rotating track, the subsequent steps are as described in S2, and because the driving column cooperates with another arc groove, the mounting plate is eventually driven to rotate in the opposite direction, so as to further adjust the working state of the drainage board; S4. When the drain plate on the mounting plate reciprocates, the adjusting top rod on the drain plate intermittently contacts the arc block on the annular plate. At the same time, the drain plate reciprocates around the rotating axis through the torsion of the torsion spring and the limit of the rotating axis. By adjusting the angle of the drain plate, the water sprayed by the sprinkler head can effectively fall evenly on the seedling cup containing the wheat seedlings.

[0016] The present invention provides a wheat seedling cultivation device and a cultivation method. Compared with the prior art, the device has the following beneficial effects: 1. The present invention puts the wheat seedlings into the seedling cup and places it on the mounting plate. After the water pump is started, the water is introduced from the water tank into the drain pipe by the water pump, and then discharged into the drain board through the outlet pipe, the telescopic hose and the connecting pipe. The water in the drain board is sprayed onto the wheat seedlings on the seedling cup through the spray head, ensuring that the wheat seedlings are properly supplied with water. 2. The present invention starts the motor and drives the driving plate and the mounting ring to rotate by using the driving shaft. When the track column slides in one of the downward pressure tracks, the track column drives the reciprocating rod on the L-shaped plate to move downward through the driving rod and the linkage shaft. At the same time, the positioning arc rod on the mounting ring cooperates with the positioning grooves on the two circular plates to drive the mounting plate to move downward through the support frame plate. When the track column continues to rotate, it will slide in one of the rotating tracks. At this time, the reciprocating rod drives the mounting plate on the support frame plate to move upward, and the driving column on the mounting ring cooperates with one of the arc grooves on the connecting column. Finally, the reciprocating rod drives the mounting plate on the support frame plate to rotate through the limit of the rotating block and the side strip. Through the descent and rotation of the mounting plate, it is convenient to adjust the height of the drainage plate on the mounting plate to ensure that the drainage plate is in a suitable position, so as to more effectively manage the spraying of water. 3. In the present invention, when the track column continues to slide and contacts with another downward pressure track, the subsequent steps are as described above, and the mounting plate is driven to descend through the support frame plate. At the same time, when the track column contacts with another rotating track, the subsequent steps are as described above, and because the driving column cooperates with another arc groove, the mounting plate is eventually driven to rotate in the opposite direction, thereby further adjusting the working state of the drainage board; 4. In the present invention, when the drain plate on the mounting plate reciprocates with the mounting plate as the center, the adjusting top rod on the drain plate intermittently contacts the arc block on the annular plate. At the same time, the drain plate reciprocates with the rotating axis as the center through the torsion of the torsion spring and the limitation of the rotating axis. By adjusting the angle of the drain plate, the water sprayed by the sprinkler head can effectively fall evenly on the seedling cup containing the wheat seedlings. BRIEF DESCRIPTION OF THE DRAWINGS

Since this technology is well known to people in this field, it will not be described in detail here.

[0022] In this embodiment, the wheat seedlings are placed in the seedling cup and placed on the mounting plate 6. After the water pump 33 is started, the water is introduced from the water tank 32 into the drain pipe 34 by the action of the water pump 33, passes through the shunt pipe 35, and then is discharged into the drain plate 38 through the outlet pipe 36, the telescopic hose 37 and the connecting pipe 39. The water in the drain plate 38 is sprayed onto the wheat seedlings on the seedling cup through the spray head 40 to ensure that the wheat seedlings are properly supplied with water. Then the motor 9 is started to use the drive shaft 10 to drive the drive plate 11 and the mounting ring 12 to rotate. When the track column 19 slides in one of the downward pressure rails 1301, the track column 19 will drive the reciprocating rod 25 on the L-shaped plate 21 to move downward through the drive rod 18 and the linkage shaft 17. At the same time, the positioning arc rod 14 on the mounting ring 12 cooperates with the positioning grooves 30 on the two circular plates 28 to drive the mounting plate 6 to move downward through the support frame plate 27. When the track column 19 continues to rotate, it will slide in one of the rotating rails 1302. At the same time, the reciprocating rod 25 will drive the mounting plate 6 on the support frame plate 27 to move upward, and the driving column 15 on the mounting ring 12 will cooperate with one of the arc grooves 31 on the connecting column 29. Finally, the reciprocating rod 25 will drive the mounting plate 6 on the support frame plate 27 to rotate through the limiting of the rotating block 24 and the side strip 26. Through the descent and rotation of the mounting plate 6, it is convenient to adjust the height of the drain plate 38 on the mounting plate 6 to ensure that the drain plate 38 is in a suitable position, which can more effectively manage the spraying of water. When the track column 19 continues to slide and slides into contact with another downward pressure rail 1301, the subsequent steps are as described above. The mounting plate 6 will be driven to descend through the support frame plate 27. At the same time, when the track column 19 slides into contact with another rotating rail 1302, the subsequent steps are as described above. And because the driving column 15 will cooperate with another arc groove 31, it will eventually drive the mounting plate 6 to rotate in the opposite direction, so as to further adjust the working state of the drain plate 38.

[0023] An auxiliary component is arranged on the bottom plate 1 of the device and on the outside of the rotating reciprocating lifting component. The auxiliary component includes a plurality of mounting grooves 41 provided on the mounting plate 6. A rotating groove 42 is provided inside the mounting groove 41. A rotating shaft 43 is rotatably installed inside the rotating groove 42. A torsion spring 44 is fixedly connected to the inner side surface of the rotating groove 42. A supporting side plate 45 is fixedly installed on the upper end surface of the bottom plate 1 of the device. An annular plate 46 is fixedly installed on the supporting side plate 45. An arc block 47 is fixedly installed on the inner side surface of the annular plate 46. An adjusting top rod 48 is fixedly installed on the outer side surface of the drain plate 38. The water plate 38 is fixedly mounted on the rotating shaft 43, and the drain plate 38 is arranged at an angle. One end of the torsion spring 44 away from the rotating groove 42 is fixedly connected to the drain plate 38, and the torsion spring 44 is located on the outside of the rotating shaft 43. The adjusting top rod 48 contacts and slides with the inner side surface of the annular plate 46 and the inner side surface of the arc block 47 respectively, and the interior of the drain plate 38 is set as a cavity to facilitate the transportation of water. When the adjusting top rod 48 contacts the arc block 47, the drain plate 38 will rotate inwardly, and at the same time, the drain plate 38 will not flip inward due to the torsion force of the torsion spring 44.

[0024] In this embodiment, when the drain plate 38 on the mounting plate 6 reciprocates with the mounting plate 6 as the center, the adjusting top rod 48 on the drain plate 38 intermittently contacts the arc block 47 on the annular plate 46. At the same time, the drain plate 38 reciprocates with the rotating shaft 43 as the center through the torsion of the torsion spring 44 and the limiting of the rotating shaft 43. By adjusting the angle of the drain plate 38, the water sprayed by the spray head 40 can effectively fall evenly on the seedling cup containing the wheat seedlings.

[0025] A method for cultivating wheat seedlings, based on the above-mentioned device for cultivating wheat seedlings, comprises the following steps: S1. Place the seedling cups containing wheat seedlings on the mounting plate 6 and arrange them in a ring shape. Start the water pump 33 to pass the water in the water tank 32 into the shunt pipe 35 through the drain pipe 34. The water in the shunt pipe 35 will be discharged into the drain plate 38 through the outlet pipe 36, the telescopic hose 37 and the connecting pipe 39. The water in the drain plate 38 will be sprayed on the seedling cups containing wheat seedlings through multiple spray heads 40. S2, then start the motor 9 and use the drive shaft 10 to drive the drive plate 11 and the mounting ring 12 to rotate. When the track column 19 slides in one of the downward pressure tracks 1301, the track column 19 will drive the reciprocating rod 25 on the L-shaped plate 21 to move downward through the drive rod 18 and the linkage shaft 17. At the same time, the positioning arc rod 14 on the mounting ring 12 cooperates with the positioning grooves 30 on the two circular plates 28 to drive the mounting plate 6 to move downward through the support frame plate 27. When the track column 19 continues to rotate, it will be in one of the rotating tracks 1302. Sliding, at this time, the reciprocating rod 25 will drive the mounting plate 6 on the support frame plate 27 to move upward, and the driving column 15 on the mounting ring 12 will cooperate with one of the arc grooves 31 on the connecting column 29, and finally the reciprocating rod 25 will drive the mounting plate 6 on the support frame plate 27 to rotate through the limit of the rotating block 24 and the side strip 26. Through the descent and rotation of the mounting plate 6, it is convenient to adjust the height of the drainage plate 38 on the mounting plate 6 to ensure that the drainage plate 38 is in a suitable position, which can more effectively manage the spraying of water; S3, when the track column 19 continues to slide and contacts with another downward pressing track 1301, the subsequent steps are as described in S2, and the mounting plate 6 is driven to descend through the support frame plate 27. At the same time, when the track column 19 slides and contacts with another rotating track 1302, the subsequent steps are as described in S2, and because the driving column 15 cooperates with another arc groove 31, the mounting plate 6 is finally driven to rotate in the opposite direction, so as to further adjust the working state of the drainage plate 38; S4. When the drain plate 38 on the mounting plate 6 reciprocates, the adjusting top rod 48 on the drain plate 38 makes intermittent contact with the arc block 47 on the annular plate 46. At the same time, the drain plate 38 swings back and forth around the rotating shaft 43 through the torsion of the torsion spring 44 and the limitation of the rotating shaft 43. By adjusting the angle of the drain plate 38, the water sprayed by the spray head 40 can effectively fall evenly on the seedling cup containing the wheat seedlings.

[0026] Working principle: When in use, the wheat seedlings are placed in the seedling cup and placed on the mounting plate 6. After the water pump 33 is started, the water is introduced from the water tank 32 into the drain pipe 34 by the water pump 33, passes through the diversion pipe 35, and then is discharged into the drain plate 38 through the outlet pipe 36, the telescopic hose 37 and the connecting pipe 39. The water in the drain plate 38 is sprayed onto the wheat seedlings on the seedling cup through the spray head 40 to ensure that the wheat seedlings are properly supplied with water. The starter motor 9 drives the drive plate 11 and the mounting ring 12 to rotate by using the drive shaft 10. When the track column 19 slides in one of the downward pressure tracks 1301, the track column 19 drives the reciprocating rod 25 on the L-shaped plate 21 to move downward through the drive rod 18 and the linkage shaft 17. At the same time, the positioning arc rod 14 on the mounting ring 12 cooperates with the positioning grooves 30 on the two circular plates 28 to drive the mounting plate 6 to move downward through the support frame plate 27. When the track column 19 continues to rotate, it will slide in one of the rotating tracks 1302. At this time, the reciprocating rod 25 will drive the mounting plate 6 on the support frame plate 27 to move upward, and the driving column 15 on the mounting ring 12 will cooperate with one of the arc grooves 31 on the connecting column 29, and finally the reciprocating rod 25 will drive the mounting plate 6 on the support frame plate 27 to rotate through the limit of the rotating block 24 and the side strip 26. By lowering and rotating the mounting plate 6, it is convenient to adjust the height of the drainage plate 38 on the mounting plate 6, ensuring that the drainage plate 38 is in a suitable position, and the water spraying can be managed more effectively; When the track column 19 continues to slide and contacts with another downward pressing track 1301, the subsequent steps are as described above, and the mounting plate 6 is driven to descend through the support frame plate 27. At the same time, when the track column 19 contacts with another rotating track 1302, the subsequent steps are as described above, and because the driving column 15 cooperates with another arc groove 31, the mounting plate 6 is finally driven to rotate in the opposite direction, so as to further adjust the working state of the drainage plate 38. When the drain plate 38 on the mounting plate 6 reciprocates around the mounting plate 6, the adjusting top rod 48 on the drain plate 38 makes intermittent contact with the arc block 47 on the annular plate 46. At the same time, the drain plate 38 swings back and forth around the rotating shaft 43 through the torsion of the torsion spring 44 and the limitation of the rotating shaft 43. By adjusting the angle of the drain plate 38, the water sprayed by the spray head 40 can effectively fall evenly on the seedling cup containing the wheat seedlings.
