Technical Field
[0001] This utility model relates to the field of maize breeding technology, and in particular to a seedling cultivation device for maize breeding and cultivation. Background Technology
[0002] Maize breeding aims to develop superior maize varieties, which is of great significance for improving maize yield, quality, and resistance. The process includes selecting breeding sites with uniform environment, few pests and diseases, and small temperature differences to provide suitable conditions for the growth of maize inbred lines. When selecting superior new varieties, high-yielding and high-quality varieties or the backbone parents of combinations are often used as the basis. Molecular marker-assisted techniques are used to develop materials with traits such as disease and pest resistance and high nutrition to combine new varieties. Maize breeding cultivation devices are specially designed for seedling cultivation in maize breeding. They are equipped with multi-layer culture boxes, which can cultivate more seedlings in a limited space, reduce the space occupied by large-scale indoor breeding, and create a more suitable and safe environment for maize seedling growth.
[0003] However, existing corn breeding and cultivation devices have different types of nozzles with varying spray ranges, angles, and atomization effects, which can easily lead to localized over- or under-spraying. This results in uneven nutrient solution spraying, causing imbalances in seedling growth and development. Some seedlings suffer root damage and excessive growth due to excessive nutrient solution, while others grow slowly and are stunted due to insufficient nutrition. This affects the overall uniformity of the plants, interferes with trait observation and screening during the breeding process, and reduces the accuracy of breeding. Utility Model Content
[0004] The purpose of this invention is to address the problem that existing corn breeding and cultivation devices have different types of nozzles with varying spray ranges, angles, and atomization effects, which can easily lead to uneven spraying of nutrient solution, resulting in unbalanced seedling growth and development. Some seedlings suffer root damage and excessive growth due to excessive nutrient solution, while others grow slowly and are stunted due to insufficient nutrition, affecting the overall uniformity of the plants, interfering with trait observation and screening during the breeding process, and reducing the accuracy of breeding. Therefore, this invention proposes a seedling cultivation device for corn breeding and cultivation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seedling cultivation device for maize breeding and cultivation, comprising a cultivation box and a spraying device. A cultivation tray is fixedly connected to the surface of the cultivation box, and multiple planting troughs are formed on the surface of the cultivation tray. The spraying device is disposed on the surface of the cultivation tray and includes a trapezoidal plate fixedly connected to the cultivation tray. A support is fixedly connected to the upper surface of the trapezoidal plate, and a tank is fixedly connected to the upper surface of the support. A feed pipe is fixedly connected to one side of the tank. A sealing plug is inserted into the surface of the tank, and a feeding pipe is fixedly connected to the lower surface of the tank. The surface of the feeding pipe has a water outlet, and a cylinder is rotatably connected to the inner wall of the feeding pipe. The surface of the cylinder has a round hole. By setting up a spray device, precise and controllable irrigation of nutrient solution is achieved. The flow of nutrient solution is controlled by the opening and closing of the round hole and the water outlet when the cylinder rotates. The irrigation time and flow rate can be flexibly adjusted according to needs, reducing nutrient solution waste and allowing the nutrient solution to drip evenly and accurately into the planting trough, providing a stable supply of water and nutrients for corn seedlings.
[0006] Preferably, the surface of the trapezoidal plate is provided with a water inlet groove, and the discharge pipe is located on the upper surface of the water inlet groove. By setting the discharge pipe, the nutrient solution flowing out of the tank is transported and guided to the trapezoidal plate, so that the nutrient solution can be accurately dripped onto the trapezoidal plate, and then flow into the planting trough through the guide groove of the trapezoidal plate to achieve accurate irrigation of the seedlings.
[0007] Preferably, one end of the cylinder passes through the feed pipe and is fixedly connected to a rocker arm. A second gear is fixedly connected to the surface of the rocker arm. By setting the rocker arm, the motor drives the first gear to rotate, which in turn drives the second gear to rotate. The second gear drives the rocker arm to rotate, and the rotation of the rocker arm causes the cylinder to rotate accordingly. When the circular hole on the cylinder corresponds to the water outlet, the nutrient solution flows out through the feed pipe for irrigation. When the cylinder continues to rotate, the circular hole moves away from the water outlet, thus closing the water outlet and stopping the flow of nutrient solution. Therefore, the rocker arm plays a key connecting and transmission role in the entire transmission process, realizing effective control of the nutrient solution spraying process.
[0008] Preferably, a motor is fixedly connected to one side of the tank, and a first gear is fixedly connected to the drive end of the motor. The first gear meshes with a second gear. By setting the motor, the first gear is driven to rotate, and then a series of transmissions drive the cylinder to rotate, thereby controlling the outflow and shut-off of the nutrient solution, so as to achieve the purpose of accurately irrigating the seedlings.
[0009] Preferably, the inner wall of the tank is provided with an observation component, which includes a sliding sleeve fixedly connected to the inner wall of the tank. A float is slidably connected to the inner wall of the sliding sleeve, and a marker is fixedly connected to the upper surface of the float. By setting up the observation component, the remaining amount of nutrient solution can be monitored intuitively and conveniently. With the float rising and falling with the nutrient solution level, the marker moves synchronously. The operator can quickly determine the amount of nutrient solution by observing the exposed length of the marker, replenish the nutrient solution in time, ensure the continuous and stable operation of the spraying device, and reduce the impact of insufficient nutrient solution on seedling cultivation.
[0010] Preferably, the upper surface of the tank has a through hole, and the marker is slidably connected to the through hole on the upper surface of the tank. By setting the marker, a visual indicator is used to determine the remaining amount of nutrient solution in the tank. Since the float floats on the surface of the nutrient solution, it will sink as the nutrient solution decreases. The marker is associated with the float and will also sink accordingly.
[0011] Preferably, a support pad is fixedly connected to the upper surface of the marker, and the length of the marker is consistent with the depth of the tank.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, a spraying device is installed. The sealing plug is removed, and the nutrient solution is poured into the feed pipe, flowing into the tank. A motor then drives the first gear to rotate, which in turn drives the second gear. The second gear's rotation causes a rocker arm to rotate, and the cylinder follows the rocker arm's rotation. When the circular hole aligns with the outlet, the nutrient solution flows out through the feed pipe and drips onto the trapezoidal plate. It then flows into the planting trough through the guide groove of the trapezoidal plate, accurately irrigating the seedlings. As the cylinder continues to rotate, the circular hole moves away from the outlet, closing the outlet and stopping the nutrient solution flow. By installing the spraying device, precise and controllable irrigation of the nutrient solution is achieved. The opening and closing of the circular hole and outlet during cylinder rotation controls the nutrient solution flow, allowing for flexible adjustment of irrigation time and flow rate as needed. This reduces nutrient solution waste and ensures the nutrient solution drips evenly and accurately into the planting trough, providing a stable supply of water and nutrients for the corn seedlings.
[0014] In this invention, by setting up an observation component, a float floats on the surface of the nutrient solution when it is lost. When the nutrient solution sinks, the float sinks with it, and the indicator rod descends accordingly. By observing the length of the indicator rod, the remaining nutrient solution can be determined, making it easy to add more nutrient solution. By setting up an observation component, the remaining amount of nutrient solution can be monitored intuitively and conveniently. With the float rising and falling with the nutrient solution level, the indicator rod moves synchronously. Operators can quickly determine the amount of nutrient solution by observing the length of the indicator rod that is exposed, and replenish the nutrient solution in a timely manner, ensuring the continuous and stable operation of the spraying device and reducing the impact of insufficient nutrient solution on seedling cultivation.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a seedling cultivation device for corn breeding and cultivation, including a cultivation box 1 and a spraying device 4. A cultivation tray 2 is fixedly connected to the surface of the cultivation box 1, and multiple planting troughs 3 are opened on the surface of the cultivation tray 2. The spraying device 4 is set on the surface of the cultivation tray 2.
[0022] In this implementation scheme: the spray device 4 includes a trapezoidal plate 42, which is fixedly connected to the cultivation tray 2. A bracket 43 is fixedly connected to the upper surface of the trapezoidal plate 42, and a tank 41 is fixedly connected to the upper surface of the bracket 43. A feed pipe 44 is fixedly connected to one side of the tank 41, and a sealing plug 45 is inserted into the surface of the feed pipe 44. A discharge pipe 412 is fixedly connected to the lower surface of the tank 41, and an outlet is opened on the surface of the discharge pipe 412. A cylinder 411 is rotatably connected to the inner wall of the discharge pipe 412, and a round hole is opened on the surface of the cylinder 411. By setting up the spray device 4, precise and controllable irrigation of nutrient solution is achieved. The flow of nutrient solution is controlled by the opening and closing of the round hole and the outlet when the cylinder 411 rotates. The irrigation time and flow rate can be flexibly adjusted according to the needs, reducing the waste of nutrient solution. It can also make the nutrient solution drip evenly and accurately onto the planting trough 3, providing a stable supply of water and nutrients for corn seedlings.
[0023] Specifically, a water inlet groove is provided on the surface of the trapezoidal plate 42, and a discharge pipe 412 is set on the upper surface of the water inlet groove. By setting the discharge pipe 412, the nutrient solution flowing out of the tank 41 is transported and guided to the trapezoidal plate 42, so that the nutrient solution can accurately drip onto the trapezoidal plate 42, and then flow into the planting trough 3 through the guide groove of the trapezoidal plate 42 to achieve accurate irrigation of the seedlings.
[0024] Specifically, one end of the cylinder 411 passes through the feed pipe 412 and is fixedly connected to a rocker arm 410. A second gear 48 is fixedly connected to the surface of the rocker arm 410. By setting the rocker arm 410, the motor 46 drives the first gear 47 to rotate, which in turn drives the second gear 48 to rotate. The second gear 48 drives the rocker arm 410 to rotate, and the rotation of the rocker arm 410 causes the cylinder 411 to rotate accordingly. When the round hole on the cylinder 411 corresponds to the water outlet, the nutrient solution flows out through the feed pipe 412 for irrigation. When the cylinder 411 continues to rotate, the round hole moves away from the water outlet, thus closing the water outlet and stopping the flow of nutrient solution. Therefore, the rocker arm 410 plays a key connecting and transmission role in the entire transmission process, realizing effective control of the nutrient solution spraying process.
[0025] Specifically, a motor 46 is fixedly connected to one side of the tank 41, and a first gear 47 is fixedly connected to the drive end of the motor 46. The first gear 47 meshes with a second gear 48. By setting the motor 46, the first gear 47 is driven to rotate, which in turn drives the cylinder 411 to rotate through a series of transmissions, thereby controlling the flow and shut-off of the nutrient solution, so as to accurately irrigate the seedlings.
[0026] Specifically, the inner wall of the tank 41 is provided with an observation component 49, which includes a sliding sleeve 494. The sliding sleeve 494 is fixedly connected to the inner wall of the tank 41. A float 493 is slidably connected to the inner wall of the sliding sleeve 494. A marker 491 is fixedly connected to the upper surface of the float 493.
[0027] In this embodiment: by setting up the observation component 49, the remaining amount of nutrient solution can be monitored intuitively and conveniently. With the help of the float 493 rising and falling with the nutrient solution level, the indicator 491 moves synchronously. The operator can quickly judge the amount of nutrient solution by observing the exposed length of the indicator 491, and replenish the nutrient solution in time to ensure the continuous and stable operation of the spraying device 4 and reduce the impact of insufficient nutrient solution on seedling cultivation.
[0028] Specifically, a through hole is provided on the upper surface of the tank body 41, and the marker rod 491 is slidably connected to the through hole on the upper surface of the tank body 41.
[0029] In this embodiment: By setting a benchmark 491, a visual indicator is set to determine the remaining amount of nutrient solution in the tank 41. Since the float 493 floats on the surface of the nutrient solution, it will sink as the nutrient solution decreases. The benchmark 491 is associated with the float 493 and will also sink accordingly.
[0030] Specifically, a support pad 492 is fixedly connected to the upper surface of the marker 491, and the length of the marker 491 is consistent with the depth of the tank 41.
[0031] Working principle: By setting up the spray device 4, removing the sealing plug 45, and then pouring the nutrient solution into the feed pipe 44, it flows into the tank 41. Subsequently, the motor 46 drives the first gear 47 to rotate, which in turn drives the second gear 48 to rotate. The rotation of the second gear 48 drives the rocker arm 410 to rotate, and the cylinder 411 follows the rocker arm 410 to rotate. When the circular hole aligns with the outlet, the nutrient solution flows out through the discharge pipe 412 and drips onto the trapezoidal plate 42. After passing through the trapezoidal plate 42... The nutrient solution flows into the planting trough 3 through the guide trough, accurately irrigating the seedlings. As the cylinder 411 continues to rotate, the round hole moves away from the outlet, and the outlet is then closed, preventing the nutrient solution from flowing out. By setting up the spray device 4, precise and controllable irrigation of the nutrient solution is achieved. The flow of the nutrient solution is controlled by the opening and closing of the round hole and the outlet when the cylinder 411 rotates. The irrigation time and flow rate can be flexibly adjusted according to the needs, reducing the waste of nutrient solution. It also allows the nutrient solution to drip evenly and accurately into the planting trough 3, providing a stable supply of water and nutrients for the corn seedlings.
[0032] By setting up the observation component 49, when the nutrient solution is lost, the float 493 floats on the surface of the nutrient solution. When the nutrient solution sinks, the float 493 sinks with it, and the indicator 491 descends accordingly. By observing the length of the indicator 491, the remaining nutrient solution can be determined, making it easy to add nutrient solution. By setting up the observation component 49, the remaining amount of nutrient solution can be monitored intuitively and conveniently. With the float 493 rising and falling with the nutrient solution level, the indicator 491 moves synchronously. Operators can quickly determine the amount of nutrient solution by observing the exposed length of the indicator 491, and replenish the nutrient solution in time to ensure the continuous and stable operation of the spraying device 4 and reduce the impact of insufficient nutrient solution on seedling cultivation.
