Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse seedling cultivation, in particular to a seedling cultivation device for a greenhouse. Background Art

[0002] Greenhouse seedling cultivation is a planting method that cultivates seedlings in a large greenhouse or shed. By utilizing environmental conditions such as temperature, humidity and light in the greenhouse, it can provide a suitable growth environment and promote plant growth and development. Greenhouse seedling cultivation can increase crop yield and quality, as well as extend the growing season of crops and increase the harvest time window. This planting method is widely used in modern agriculture.

[0003] In order to increase the planting space inside the greenhouse, a seedling rack is used to cultivate crops. For example, Chinese patent CN216906105U discloses a greenhouse seedling rack, which uses a booster pump to send water in a water tank into a door-shaped tube through a hose and sprays it out through a nozzle, while driving the door-shaped tube to move back and forth on the left and right sides of the seedling tray to replenish water for the seedlings, eliminating the need for manual hand-held water spraying. However, the upper and lower adjacent seedling trays block each other, the range of water replenishment on the bottom seedling tray is limited, and the water replenishment on the multi-layer seedling trays is uneven, which is not conducive to the growth of crops on the bottom seedling tray. Therefore, we propose a seedling raising device for a greenhouse. Utility Model Content

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a seedling raising device for a greenhouse, comprising a base, four columns installed on the base and distributed in a rectangular shape, a connecting rod connected between the two columns on the left and the two columns on the right, a water replenishment component installed on the top of the base, and a driving component installed on the top of the base and driving the water replenishment component to move, a seedling raising tray is provided between the columns on the left and right sides, guide rails are installed on the front and back sides of the seedling raising tray, the outer side of the guide rail is slidably connected to a clamping column having one end engaged with the connecting rod, a support component is provided at the bottom of the seedling raising tray, and an anti-retraction component is also provided on the support component.

[0006] By adopting the above technical scheme, the driving component drives the water replenishing component to move, so that the crops on a single seedling tray can be evenly replenished with water. The seedling tray is connected to the column through the clamping column and the connecting support rod. The distance between two adjacent seedling trays can be changed by clamping with the connecting support rods at different heights above and below, which is convenient for adjustment according to the growth status of the crops and is more conducive to the growth of crops. At the same time, the seedling tray is movably connected to the connecting support rod through a guide rail, and the seedling tray can be slid left or right, and the seedling tray is supported by the supporting component, so that each layer of the seedling tray can be replenished with water one by one, ensuring that the crops on each layer of the seedling tray can be evenly replenished with water, which is more conducive to the growth of crops. The anti-retraction component can prevent the support component from retracting and separating from the supporting surface, thereby improving the stability of the support for the seedling tray and avoiding the seedling tray from tipping over after sliding out to the left or right.

[0007] The utility model is further configured as follows: the driving assembly includes a connecting transverse groove opened at the bottom of the base and located on the front and rear sides of the column, a driving motor installed on one of the connecting transverse grooves, a screw rod fixedly connected to the output shaft of the driving motor and rotatably connected to the inner wall of the connecting transverse groove, and a sliding block threadedly connected to the outside of the screw rod and movably connected to the inner wall of the connecting transverse groove.

[0009] By adopting the above technical solution, the driving motor is started to drive the screw rod to rotate forward or reversely, and the sliding block is threadedly connected to the screw rod and movably connected to the inner wall of the connecting transverse groove, so that the sliding block can move left and right to drive the water replenishment component to move evenly to replenish water for the crops on the seedling tray, and the guide block moves outside the guide rod to support and cooperate with the water replenishment component to move.

[0010] The utility model is further configured as follows: the water replenishment component includes a reflux groove opened on the top of the base and located between the connecting transverse grooves on the front and rear sides, a water pump installed in the reflux groove, a hose connected to the water pump, a gate-type pipe connected to the hose, and a nozzle connected to the gate-type pipe.

[0011] By adopting the above technical solution, the water pump draws water or nutrient solution back into the water tank and sprays the nutrient solution out through the hose, the gate-type pipe and the nozzle to replenish water for the crops.

[0012] The utility model is further configured as follows: the bottom wall of the reflux trough is inclined, the water pump is installed on the inner wall of the reflux trough at one end that is inclined downward, and a supporting mesh plate is installed in the reflux trough.

[0013] By adopting the above technical solution, it is more conducive for the water pump to extract water or nutrient solution in the water pump to replenish water for crops, and the support mesh plate provides a support surface for the support component.

[0014] The utility model is further configured as follows: two ends of the bottom of the gate-shaped tube are fixedly connected to a guide block and a sliding block respectively, and the column is installed in the reflux groove.

[0015] By adopting the above technical solution, the sliding block can move left and right to drive the gate-shaped tube to move left and right, and the guide block supports the gate-shaped tube to move together, so that the sprinkler can evenly replenish water to the crops on each layer of the seedling tray.

[0017] By adopting the above technical scheme, the seedling tray is movably connected to the connecting support rod through the guide rail, and the seedling tray can be slid to the left or right. After the seedling tray slides out, in order to improve the stability of the seedling tray, the supporting inner rod is flipped downward to separate the positive magnet from the negative magnet, and the supporting inner rod moves downward to contact the ground when the supporting sleeve rod is moved, so as to support the seedling tray.

[0018] The utility model is further configured as follows: the seedling raising tray is a concave tray, and the inner bottom wall of the seedling raising tray is designed in a mesh shape.

[0019] By adopting the above technical solution, after water replenishment, excess water or nutrient solution in each seedling tray can flow downward and be recovered through the reflux groove for reuse.

[0020] The utility model is further configured as follows: the anti-retraction assembly includes a retaining plate hinged on the inner wall of the support sleeve rod, a connecting spring connected between the retaining plate and the inner wall of the support sleeve rod, and a pull rod connected to the retaining plate and extending through the connecting spring to the outside of the support sleeve rod.
