Description

Technical Field

[0001] This invention relates to the field of seed cultivation technology, specifically to a humidification test chamber for oat seed germination. Background Technology

[0002] Oat seeds need to undergo germination tests to assess their germination ability, seed vigor, and whether they meet sowing requirements. Seed germination tests are a core inspection method for assessing sowing quality by controlling environmental conditions such as temperature and humidity to detect the ability of crop or forest seeds to germinate normally within a specified time.

[0003] For example, in a seed germination test chamber with announcement number CN213044118U, L-shaped planting plates are movably connected at equal intervals to the back of an inclined long rod. A convex locking block is fixedly connected to the right side of the L-shaped planting plate. A sliding rod groove is opened on the back of the inclined long rod, and a sliding rod is connected through the inner wall of the sliding rod groove. Placement plate grooves are opened at equal intervals on both sides of the inner wall of the sliding rod groove, and placement plates are connected through the inner wall of the placement plate groove. Upper limit blocks are fixedly connected to the top of both sides of the roller rod, and lower limit blocks are fixedly connected to both sides of the roller rod. The top of the lower limit blocks is in contact with the bottom of the inner box. A rocker arm shaft fixing block is movably connected to the middle of the rocker arm through a bearing E. A long push rod is movably connected to the right side of the top of the roller rod, and concave locking blocks are fixedly connected at equal intervals to the left side of the long push rod. The L-shaped planting plates, which move out in a stepped shape, can facilitate the germination of seeds to absorb light and replenish water, thereby improving the practicality of the seed germination test chamber.

[0004] However, the watering method varies depending on the growth stage of the seeds in the germination tray. In the initial stage, simple spraying is sufficient. When the seeds are in the seedling stage, it is necessary to rinse the roots of the seedlings to simulate rainwater washing and prevent mold. The existing ordinary spraying watering method is difficult to meet the needs of different growth stages, which will affect the germination rate of oat seeds. In addition, water should be drained in time after watering to avoid seed hypoxia, suffocation or rotting. Summary of the Invention

[0005] The purpose of this invention is to provide a humidification test chamber for oat seed germination, so as to solve the problem that it is inconvenient to adjust the water replenishment method according to the growth stage of the seeds, which will affect the germination rate of oat seeds and reduce the accuracy of germination test results.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a humidification test chamber for oat seed germination, comprising a chamber body and a base frame fixedly installed at the bottom of the chamber body, a door hinged to one side of the front of the chamber body, a water replenishment component provided on one side of the interior of the chamber body, and a spray component provided on the other side of the interior of the chamber body; Also includes: The water replenishment component includes a germination tray that is rotatably mounted on the back side of the inner wall of the box. A horizontal plate is fixedly installed inside the germination tray. A connecting pipe is fixedly installed in the horizontal plate with evenly spaced openings inside. A spiral groove is opened on the inner bottom surface of the horizontal plate. A water storage box is fixedly connected to the top side of the germination tray. A water filling pipe is fixedly connected to the top of the water storage box at the top. A bent plate is slidably installed inside the water storage box, and a lower pipe is installed between the water storage box and the spiral groove.

[0007] Preferably, a rotating rod is fixedly connected to the back of the germination tray, a torsion spring is sleeved on the outside of the rotating rod, one end of the torsion spring is fixedly connected to the box body, the other end of the torsion spring is fixedly connected to the back of the germination tray, a fixing ring is fixedly connected to the back of the box body, a nut is threadedly connected to the outside of the rotating rod, the nut and the fixing ring are rotatably installed, the horizontal plate is in contact with the top surface of the spiral groove, the water inlet pipe passes through the top surface of the box body, a drain hole is opened at the bottom of the spiral groove, a temporary storage box is vertically and evenly slidably installed inside the box body, and a sealing plate is fixedly connected to one side of the top of the temporary storage box.

[0008] By adopting the above technical solution, water can be replenished to the germination tray from top to bottom. With the cooperation of the water storage box, spiral groove and drain hole, the water in the water storage box will flow into the spiral groove after replenishment, thus realizing autonomous water replenishment. During water replenishment, the weight of the water in the water storage box will drive the germination tray to a horizontal position, maintaining a uniform rinsing of the seedling roots. After rinsing, the counterweight will drive the germination tray to return to the tilted position, which will facilitate the drainage of the water remaining in the spiral groove and reduce the impact of water accumulation.

[0009] Preferably, a drain pipe is connected between the horizontal plate and the lower water storage box, the top end of the drain pipe is connected to the spiral groove, the drain hole is located on the side of the spiral groove away from the water storage box, a counterweight is fixedly connected to the bottom of the horizontal plate, and a back rod is fixedly connected to the inner bottom surface of the box.

[0010] By adopting the above technical solution, the operator connects the water inlet pipe to the external water pipe, and the water enters the uppermost water storage box. As the water level in the water storage box rises, the pressure of the water flow at the bottom will squeeze the bending plate, so that the stepped groove is connected to the lower pipe, and the water in the water storage box enters the spiral groove through the lower pipe.

[0011] Preferably, a fixing block is fixedly connected to the outer side of the back rod, a spring is sleeved on the outer side of the back rod, a movable plate is fixedly connected to one side of the temporary storage box, the movable plate is slidably connected to the back rod, and the two ends of the spring are fixedly connected to the fixing block and the movable plate respectively.

[0012] By adopting the above technical solution, the weight of the water in the water storage box drives the germination plate to rotate to a horizontal position. The germination plate drives the rotating rod to rotate, and the rotating rod acts on the torsion spring. The elastic force of the spring drives the moving plate to rise, and the moving plate drives the temporary storage box to rise.

[0013] Preferably, a conduit is connected between the temporary storage box and the drain pipe, a bending plate is slidably connected to one side of the water storage box, the bottom surface of the bending plate is in contact with the inner bottom surface of the water storage box, an outer plate is fixedly connected to one side of the bending plate through the water storage box, a spring is fixedly connected between the outer plate and the water storage box, and a stepped groove is transversely opened inside the bending plate.

[0014] By adopting the above technical solution, the water remaining in the spiral groove flows into the storage box through the drain hole, and then flows into the drain pipe through the conduit, so that the water in the spiral groove is fully discharged.

[0015] Preferably, a piston rod is fixedly connected to the inner wall of the water storage box near the outer plate, the piston rod is slidably connected to the stepped groove, a side pipe is fixedly connected between adjacent water storage boxes, a solenoid valve is fixedly installed on the outer side of the side pipe, and a blocking block is fixedly connected parallel to one side of the back of the box.

[0016] By adopting the above technical solution, as the water level in the water storage box rises, the pressure of the water flow at the bottom will squeeze the bending plate, and the bending plate will also drive the outer plate to move. The outer plate stretches the second spring, so that the stepped groove is connected to the lower pipe.

[0017] Preferably, the spraying assembly includes a connecting plate fixedly installed on one side of the inner wall of the box. The number of connecting plates is the same as that of the germination tray, and there are no fewer than three of them. The connecting plate has a slanted groove on both the front and back sides. An electric push rod is also fixedly installed on one side of the inner wall of the box.

[0018] By adopting the above technical solution, the connecting plate is located above the germination tray, which facilitates the spray humidification operation.

[0019] Preferably, the number of electric push rods is the same as that of the connecting plate, the output end of the electric push rod is fixedly connected to a magnet, a U-shaped block is sleeved on the outer side of the inclined groove, and guide rods are symmetrically fixedly connected to the inner side of the U-shaped block.

[0020] By adopting the above technical solution, water passes through the cavity inside the U-shaped block and is sprayed out from the spray head. The electric push rod drives the magnet to extend and retract. The extension of the magnet drives the U-shaped block to move, and the U-shaped block drives the guide rod to move. The guide rod slides inside the inclined groove.

[0021] Preferably, the guide rod is slidably connected to the inclined groove, spray heads are uniformly fixedly installed on the bottom of the U-shaped block, and an outer tube is fixedly connected to one side of the U-shaped block. The outer tube passes through the back of the box and communicates with the outside.

[0022] By adopting the above technical solution, the outer pipe is connected to the external pressurized water pipe, and the outer pipe uses a telescopic flexible hose for easy extension and adjustment.

[0023] Compared with the prior art, the beneficial effects of this invention are as follows: By setting up a water replenishment component, the germination tray is initially tilted to the lower right, with an tilt angle ranging from zero to five degrees. Utilizing the cooperation of the water inlet pipe and the germination tray, water is replenished to the germination tray sequentially from top to bottom. Through the cooperation of the water storage box, spiral groove, and drain hole, water in the water storage box flows into the spiral groove after replenishment, thus achieving autonomous water replenishment. During water replenishment, the weight of the water in the water storage box drives the germination tray to a horizontal position, maintaining uniform rinsing of the seedling roots. After rinsing, the counterweight drives the germination tray back to the tilted state, facilitating the drainage of residual water in the spiral groove and reducing the impact of water accumulation. This achieves the effects of autonomous water replenishment, rinsing of seedling roots, and timely drainage, making it suitable for watering oat seedlings. Specific details are as follows: By setting up a water supply component, the top of the horizontal plate is filled with soil. Operators then evenly cultivate oat seeds in the connecting pipe. Before the seeds germinate, a spray system is used to spray water and humidify the area. Once the seeds have grown into seedlings, the operator connects the water supply pipe to an external water pipe, allowing water to enter the uppermost water storage box. As the water level in the storage box rises, the pressure from the lower part of the water flow compresses the bending plate. Furthermore, due to the obstruction of the left-side blocking block, the weight of the water in the storage box causes the germination tray to rotate to a horizontal position. The germination tray drives the rotating rod to rotate, which in turn acts on the torsion spring. The spring force of spring one causes the moving plate to rise, which in turn causes the temporary storage box to rise. The temporary storage box causes the sealing plate to press tightly against the drain hole, reducing water leakage. The bending plate also causes the outer plate to move, which stretches spring two, connecting the stepped groove to the lower pipe. Water in the water storage box enters the spiral groove through the lower pipe. The roots of the seedlings pass through the horizontal plate and are located inside the spiral groove, allowing the water in the spiral groove to flush the roots of the seedlings. Furthermore, the water flows from the drain... Water flows into the next water storage box, causing the next germination tray to rotate to a horizontal position. Finally, the water is discharged from the bottom drain pipe. After the water has finished rinsing the seedling roots, the solenoid valve of the side pipe is opened, and the water remaining in the water storage box flows out from the side pipe and finally out from the bottom drain pipe. As the water in the water storage box is discharged, the weight of the counterweight will drive the germination tray to rotate. The elastic force of the torsion spring will drive the germination tray back to the initial tilted position. The blocking block will limit the germination tray again. At this time, the bottom of the germination tray will press the sealing plate. The sealing plate will drive the temporary storage box and the moving plate to descend. The moving plate will stretch the spring. At this time, the sealing plate will release the sealing block on the drain hole. The tilted state of the germination tray will facilitate the discharge of the water remaining in the spiral groove. The water remaining will flow into the temporary storage box through the drain hole and then into the drain pipe through the guide tube, so that the water in the spiral groove is fully discharged. This device achieves the effects of autonomous water replenishment, water replenishment and rinsing of seedling roots, and timely drainage. It is suitable for water replenishment of oat seedlings. By setting up the spray assembly, the operator connects the outer tube to the external pressurized water pipe and simultaneously activates the electric push rod. Water passes through the cavity inside the U-shaped block and is sprayed out from the spray head. The electric push rod drives the magnetic block to extend and retract. The magnetic block is magnetically connected to the U-shaped block. When the magnetic block extends, it moves the U-shaped block, which in turn moves the guide rod. The guide rod slides inside the inclined groove, and the inclination angle of the inclined groove is the same as the initial position of the germination tray. This causes the U-shaped block to move and raise the spray head. When the electric push rod retracts, the magnetic block drives the U-shaped block to slide back to its original position, allowing the spray head to spray and humidify the oat seeds on the top of the horizontal plate.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 - Figure 3 The present invention provides a technical solution: a humidification test chamber for oat seed germination, comprising a chamber body 1 and a base frame 2 fixedly installed at the bottom of the chamber body 1, a door 3 hinged to one side of the front of the chamber body 1, a water replenishment component 4 provided on one side of the interior of the chamber body 1, and a spray component 5 provided on the other side of the interior of the chamber body 1.

[0028] like Figure 1 and Figure 4 - Figure 11 As shown, the water replenishment component 4 includes a germination tray 41 that is rotatably mounted on one side of the inner wall of the box 1. A horizontal plate 46 is fixedly installed inside the germination tray 41. A connecting pipe 47 is fixedly installed with evenly spaced holes inside the horizontal plate 46. A spiral groove 48 is provided on the inner bottom surface of the horizontal plate 46. A water storage box 49 is fixedly connected to one side of the top of the germination tray 41. A water filling pipe 410 is fixedly connected to the top of the uppermost water storage box 49. The water filling pipe 410 is used to connect to an external water pipe to replenish water.

[0029] A rotating rod 42 is fixedly connected to the back of the germination tray 41. A torsion spring 43 is sleeved on the outside of the rotating rod 42. One end of the torsion spring 43 is fixedly connected to the box body 1, and the other end of the torsion spring 43 is fixedly connected to the back of the germination tray 41. A fixing ring 44 is fixedly connected to the back of the box body 1. A nut 45 is threadedly connected to the outside of the rotating rod 42. The nut 45 and the fixing ring 44 are rotatably installed. When the germination tray 41 rotates, the germination tray 41 will drive the rotating rod 42 to rotate, and the rotating rod 42 will drive the nut 45 to rotate, thereby maintaining the stable rotation of the germination tray 41.

[0030] The top surface of the horizontal plate 46 is attached to the top surface of the spiral groove 48, the water pipe 410 passes through the top surface of the box 1, the bottom of the spiral groove 48 is provided with a drain hole 412, a temporary storage box 418 is vertically and evenly slidably installed inside the box 1, and a sealing plate 419 is fixedly connected to one side of the top of the temporary storage box 418. When the germination plate 41 is in an inclined state, the sealing plate 419 does not seal or block the drain hole 412.

[0031] A drain pipe 411 is connected between the horizontal plate 46 and the lower water storage box 49. The top end of the drain pipe 411 is connected to the spiral groove 48, so that the water in the spiral groove 48 can flow into the next water storage box 49 through the drain pipe 411. The drain hole 412 is located on the side of the spiral groove 48 away from the water storage box 49. A counterweight block 413 is fixedly connected to the bottom of the horizontal plate 46, and a back rod 414 is fixedly connected to the inner bottom surface of the box 1.

[0032] A fixing block 415 is fixedly connected to the outside of the back rod 414, and a spring 417 is sleeved on the outside of the back rod 414. A movable plate 416 is fixedly connected to one side of the temporary storage box 418. The movable plate 416 is slidably connected to the back rod 414. The two ends of the spring 417 are fixedly connected to the fixing block 415 and the movable plate 416 respectively. The number of temporary storage boxes 418 is the same as that of the germination tray 41, and the temporary storage boxes 418 are located at the bottom of the germination tray 41 on the side away from the water storage box 49.

[0033] A bending plate 421 is slidably installed inside the water storage box 49. A lower pipe 426 is installed between the water storage box 49 and the spiral groove 48. When the bending plate 421 moves, it will drive the outer plate 422 to move. The outer plate 422 stretches the second spring 423, so that the stepped groove 424 is connected to the lower pipe 426. The water in the water storage box 49 enters the spiral groove 48 through the lower pipe 426.

[0034] A conduit 420 connects the temporary storage box 418 and the drain pipe 411. The water remaining in the spiral groove 48 flows into the temporary storage box 418 through the drain hole 412, and then flows into the drain pipe 411 through the conduit 420, so that the water in the spiral groove 48 is fully discharged.

[0035] A bent plate 421 is slidably connected to one side of the water storage box 49. The bottom surface of the bent plate 421 is in contact with the inner bottom surface of the water storage box 49. An outer plate 422 is fixedly connected to one side of the bent plate 421 through the water storage box 49. A spring 423 is fixedly connected between the outer plate 422 and the water storage box 49. A stepped groove 424 is transversely opened inside the bent plate 421.

[0036] A piston rod 425 is fixedly connected to the inner wall of the water storage box 49 near the outer plate 422. The piston rod 425 is slidably connected to the stepped groove 424. A side pipe 427 is fixedly connected between adjacent water storage boxes 49. A solenoid valve is fixedly installed on the outside of the side pipe 427. After the water has finished rinsing the roots of the seedlings, the solenoid valve of the side pipe 427 is opened, and the water remaining in the water storage box 49 flows out from the side pipe 427 and finally flows out from the bottom drain pipe 411. A blocking block 428 is fixedly connected in parallel to one side of the back of the box 1.

[0037] Example 1: As Figure 4 - Figure 11 As shown, the top of the horizontal plate 46 is filled with soil. The operator cultivates oat seeds evenly in the connecting pipe 47. Before the seeds germinate, they are sprayed with water and humidified by the spray component 5. After the seeds grow into seedlings, the operator connects the water pipe 410 to the external water pipe, and the water enters the uppermost water storage box 49. As the water level in the water storage box 49 rises, the pressure of the water flow at the bottom will squeeze the bending plate 421. Due to the obstruction of the left blocking block 428, the weight of the water in the water storage box 49 drives the germination plate 41 to rotate to a horizontal position. The germination plate 41 drives the rotating rod 42 to rotate. The rotating rod 42 acts on the torsion spring 43. The elastic force of the spring 417 drives the moving plate 416 to rise. The moving plate 416 drives the temporary storage box 418 to rise. The temporary storage box 418 drives the sealing plate 419 to fit tightly against the drain hole 412, reducing the leakage of water from the drain hole 412.

[0038] The bending plate 421 also drives the outer plate 422 to move. The outer plate 422 stretches the second spring 423, so that the stepped groove 424 is connected to the lower pipe 426. The water in the water storage box 49 enters the spiral groove 48 through the lower pipe 426. The roots of the seedling pass through the horizontal plate 46 and are located inside the spiral groove 48, so that the water in the spiral groove 48 washes the roots of the seedling. The water flows from the drain pipe 411 into the next water storage box 49, so that the next germination plate 41 rotates to a horizontal position.

[0039] Finally, the water is discharged from the bottom drain pipe 411. After the water has flushed the roots of the seedlings, the solenoid valve of the side pipe 427 is opened, and the water remaining in the water storage box 49 flows out from the side pipe 427 and finally out from the bottom drain pipe 411. As the water in the water storage box 49 is discharged, the weight of the counterweight 413 will cause the germination plate 41 to rotate. The elastic force of the torsion spring 43 will cause the germination plate 41 to return to its initial tilted position. At this time, the bottom of the germination plate 41 will press the sealing plate 419, and the sealing plate 419 will drive the temporary storage box 4 When the 18th and the moving plate 416 descend, the moving plate 416 stretches the spring 417. At this time, the sealing plate 419 releases its seal on the drainage hole 412. The tilted state of the germination plate 41 facilitates the discharge of residual water in the spiral groove 48. The residual water flows into the temporary storage box 418 through the drainage hole 412, and then flows into the drain pipe 411 through the conduit 420, so that the water in the spiral groove 48 is fully discharged. This achieves the effects of autonomous water replenishment, water replenishment and flushing of seedling roots, and timely drainage. It is suitable for water replenishment of oat seedlings.

[0040] like Figure 1 and Figure 12 - Figure 13 As shown, the spray assembly 5 includes a connecting plate 51 fixedly installed on one side of the inner wall of the box 1. The number of connecting plates 51 is the same as that of the germination tray 41, and there are no fewer than three of them. The connecting plate 51 has a slanted groove 52 on both the front and back sides. An electric push rod 57 is also fixedly installed on one side of the inner wall of the box 1.

[0041] The number of electric push rods 57 is the same as that of connecting plate 51. A magnet block 58 is fixedly connected to the output end of the electric push rod 57. A U-shaped block 53 is sleeved on the outside of the inclined groove 52. A guide rod 54 is symmetrically fixedly connected to the inside of the U-shaped block 53.

[0042] The guide rod 54 is slidably connected to the inclined groove 52. Spray heads 55 are evenly fixedly installed on the bottom of the U-shaped block 53. An outer tube 56 is fixedly connected to one side of the U-shaped block 53. A cavity is opened inside the U-shaped block 53. The outer tube 56 is connected to the spray head 55 through the cavity. The outer tube 56 passes through the back of the box 1 and communicates with the outside.

[0043] Example 2: Figure 12 - Figure 13As shown, the operator connects the outer tube 56 to the external pressurized water pipe and simultaneously activates the electric push rod 57. Water passes through the cavity inside the U-shaped block 53 and is sprayed out from the spray head 55. The electric push rod 57 drives the magnet block 58 to extend and retract. The magnet block 58 is magnetically connected to the U-shaped block 53. When the magnet block 58 extends, it drives the U-shaped block 53 to move. The U-shaped block 53 drives the guide rod 54 to move. The guide rod 54 slides inside the inclined groove 52. The inclination angle of the inclined groove 52 is the same as the initial position of the germination plate 41, so that the U-shaped block 53 drives the spray head 55 to move and rise at the same time. When the electric push rod 57 retracts, the magnet block 58 drives the U-shaped block 53 to slide back to its original position, so that the spray head 55 sprays and humidifies the oat seeds on the top of the horizontal plate 46.

[0044] Working principle: When using this device, firstly, as... Figure 1 - Figure 13 As shown, before the seeds germinate, the operator connects the outer tube 56 to the external pressurized water pipe and simultaneously activates the electric push rod 57. Water passes through the cavity inside the U-shaped block 53 and is sprayed out from the spray head 55. The spray head 55 sprays and humidifies the oat seeds at the top of the horizontal plate 46. After the seeds grow into seedlings, the operator connects the water inlet pipe 410 to the external water pipe, and the water enters the uppermost water storage box 49. The weight of the water in the water storage box 49 causes the germination tray 41 to rotate to a horizontal position. The water in the water storage box 49 then flows through the lower pipe 426 into the spiral groove 48. The roots of the seedlings pass through the horizontal plate 46 and are located inside the spiral groove 48, allowing the water in the spiral groove 48 to wash over the roots of the seedlings. The water also flows from the drain pipe 411 into the next water storage box 49, causing the next germination tray 41 to rotate to a horizontal position. Finally, the water is discharged from the lowermost drain pipe 411. After the water has finished washing over the roots of the seedlings... After completion, open the solenoid valve of the side tube 427. The water remaining in the water storage box 49 flows out from the side tube 427 and finally flows out from the bottom drain pipe 411. As the water in the water storage box 49 is discharged, the weight of the counterweight 413 will drive the germination plate 41 to rotate. The elastic force of the torsion spring 43 will drive the germination plate 41 back to the initial tilt position. At this time, the bottom of the germination plate 41 will squeeze the sealing plate 419. The sealing plate 419 will drive the temporary storage box 418 and the moving plate 416 to descend. The moving plate 416 stretches the spring 417. At this time, the sealing plate 419 releases the sealing block on the drain hole 412. The residual water flows into the temporary storage box 418 through the drain hole 412. The water then flows into the drain pipe 411 through the conduit 420, so that the water in the spiral groove 48 is fully discharged. This realizes the effects of autonomous water replenishment, water replenishment and flushing of seedling roots, and timely drainage. It is suitable for water replenishment of oat seedlings.
