Description

Technical Field

[0001] The invention relates to the technical field of seedling cultivation, and more particularly to an intelligent seedling cultivation greenhouse. Background Art

[0002] Crop seedling cultivation is an important step in breeding, and a greenhouse environment is often used during the seedling cultivation process. Greenhouse seedling cultivation not only occupies a small area, but also facilitates the control of temperature, humidity, light and ventilation in the greenhouse. At the same time, it can adjust the environment in the greenhouse to carry out barrier-free seedling cultivation at different times, making crop cultivation more efficient and convenient. At the same time, the temperature and humidity in the greenhouse are adjusted, and the temperature is adjusted while ventilating the greenhouse, so that the temperature is always maintained in an environment suitable for seedling cultivation.

[0003] In the process of seedling cultivation, the use of seedling trays is more common. During seedling cultivation, the overall environmental temperature and humidity in the greenhouse are adjusted to keep the temperature of the seedlings at a suitable germination temperature for the current crop. In order to ensure the germination rate and the seedling division after successful seedling cultivation, which is easy to operate and does not damage the root system, the seedling tray is often filled with gravel and a culture medium layer is laid on the upper layer. The water permeability of gravel can prevent the seedlings from drowning even if they are watered too much. In this way, during the growth of the root system after germination, it will be easy to take root in the gaps between the gravel and the sand, and it is easy to ventilate to avoid seedling death caused by uneven dryness and wetness. However, due to the poor water storage performance of gravel, more watering is required, and excess water needs to be removed in time. Therefore, a drain tray is required under the seedling tray for support. In order to cultivate seedlings in batches, multiple seedling trays are arranged on the frame at intervals during the seedling cultivation process. At the same time, the orientation of the seedling trays on the frame can be adjusted to avoid uneven growth of seedlings due to uneven light. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide an intelligent seedling cultivation greenhouse which can effectively utilize the space in the greenhouse and is easy to adjust the temperature.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] An intelligent seedling cultivation greenhouse comprises a greenhouse main body, a drainage channel is arranged on the side of the greenhouse main body, a ventilation pipe is arranged on the upper end of the inner side of the greenhouse main body, a plurality of air outlets are arranged on the ventilation pipe, a cooling air duct is arranged at the lower end of the drainage channel, a fan is arranged on the side of the greenhouse main body, the ventilation pipe and the cooling air duct are respectively connected to the fan, one end of the cooling air duct is connected to the fan and the other end is connected to the greenhouse main body, a seedling raising rack is arranged in the greenhouse main body, a drain tray is arranged at the lower end of the seedling raising rack, a downward drain pipe is arranged on the side of the drain tray, and the lower end of the drain pipe extends out of the greenhouse main body and extends into the drainage channel.

[0009] Preferably, the middle part of the left and right end surfaces of the drain tray are laterally rotatably connected to the arch frame, the lower end surface of the drain tray is provided with a plurality of longitudinally arranged guide grooves, the front and rear ends of the drain tray are respectively provided with drain grooves, each guide groove is respectively connected to the drain groove, and the outer side surface of the drain groove is rotatably connected to the drain pipe.

[0010] Preferably, the drain pans on the arch frame are arranged in a vertical array and parallel to each other, and the sides of the drain pans are rotatably connected to the drain pipe, and the rotation angle of the drain pan is controlled by the lifting movement of the drain pipe.

[0011] Preferably, the greenhouse body comprises a transversely arranged ground fixing plate, to which a plurality of top support rods are respectively connected, the top support rods are arranged in a transverse array, and the outer sides of the top support rods are covered with a protective layer.

[0012] Preferably, the ventilation pipe is arranged transversely and located at the upper end of the inner side of the top support rod, and the ventilation pipe is fixedly connected to each top support rod.

[0016] The technical solution of the present invention achieves the following beneficial technical effects:

[0017] During seedling raising, the seedlings are raised in seedling trays. During the seedling raising process, excess water flows downward from the seedling trays into the drain tray to avoid water accumulation in the seedling trays which may lead to root death of the seedlings. The water in the drain trays is discharged outward into the drainage ditch located outside the greenhouse.

[0018] The temperature in the greenhouse can be adjusted in real time. During the process of adjusting the temperature in the greenhouse, when cooling is needed, a flat cooling pipe is provided at the lower end of the drainage channel. Heat is exchanged with the drainage channel through the cooling pipe, and the cooled air is input into the greenhouse for cooling. When cooling is not needed and only ventilation is needed, the outside air is directly input into the greenhouse for ventilation through the fan. At the same time, in order to avoid uneven wind force, the diameter of the air outlet on the ventilation duct in the greenhouse is smaller the closer it is to the fan, thereby reducing the difference in air outlets between the various air outlets.

DETAILED DESCRIPTION

[0027] This embodiment is described in detail with reference to the accompanying drawings.

[0028] When in use, first build the greenhouse body 1, which includes a ground fixing plate 16 fixedly connected to the ground. The width between the ground fixing plates 16 is the width of the greenhouse. A plurality of sockets are evenly spaced on the ground fixing plates 16. The two ends of the top support rod 17 with an arc-shaped top are respectively inserted into the sockets on the ground fixing plates 16, and then the top support rods 17 are connected and fixed in sequence. After the ground fixing plates 16 and the top support rods 17 are fixed, the main frame of the greenhouse is built. A protective layer is covered on the main frame of the greenhouse. The protective layer is divided into multiple types, and the protective layer is divided into an inner layer and an outer layer. The inner layer is fitted on the main frame of the greenhouse. The greenhouse body 1 is on a frame, and the inner layer is a plastic film layer, while the outer layer is selected according to the season. It is a sun protection layer in summer and a heat preservation layer in winter. After the greenhouse body 1 is built, a drainage channel 2 is provided on the side of the greenhouse, and a cooling air duct 5 is fixedly installed at the bottom of the drainage channel 2. The cooling air duct 5 is a flat structure that maximizes the contact area as much as possible, and both ends of the cooling air duct 5 extend out of the drainage channel 2 respectively. A fan 6 is fixedly installed on the side of the greenhouse body 1, and a ventilation pipe 3 arranged horizontally and running through the greenhouse is fixedly connected to the upper end of the inner side of the greenhouse body 1. The fan 6 is connected to one end of the ventilation pipe 3 and the cooling air duct 5, and the other end of the cooling air duct 5 is connected to the other side of the greenhouse.

[0029] When ventilating the greenhouse, the ventilation pipe 3 is located at the upper end of the inner side of the greenhouse, and a plurality of air outlets 4 are provided at the lower end of the ventilation pipe 3. The diameters of the air outlets 4 are different. In order to reduce the difference in the air volume of each air outlet 4 when the fan 6 is conveying, the diameter of the air outlet close to the fan 6 is smaller than the diameter of the air outlet far away from the fan 6. In this way, the difference in the air volume at both the end far away from the fan 6 and the end close to the fan 6 can be reduced. At the same time, in order to avoid the wind from the air outlet from being directly ejected outward through the small holes, which is not only easy to cause noise but also causes the wind circulation to be incomplete, an arc-shaped cover with an opening downward is connected to the lower end of each air outlet. The wind is disturbed by the arc-shaped cover to avoid the generation of small wind columns and reduce noise, and at the same time, the wind in the greenhouse can be guided.

[0030] The operation of the fan 6 is divided into two modes, one is that the greenhouse is only ventilated, and the other is to adjust the temperature in the greenhouse while ventilating. In the first mode of ventilation only, the fan 6 draws air from the outside of the greenhouse directly into the ventilation pipe 3, and then the ventilation pipe 3 evenly outputs wind force to complete the ventilation cycle in the greenhouse. During a small amount of cooling, the fan 6 can be reversed to directly draw the air in the greenhouse out of the ventilation pipe 3. Due to the physical property that hot air will be concentrated at the top, the hot air in the upper layer is directly extracted, and then supplemented with lower temperature air from the outside to achieve a lower degree of cooling.

[0031] In the second case, when a long period of time and a large amount of cooling is required, which often occurs in summer and in a hotter environment, the air outlet of the fan 6 is connected to one end of the cooling air duct 5, and the other end of the cooling air duct 5 is connected to the greenhouse. When cooling, it is an internal circulation. The fan 6 draws the air in the cooling air duct 5 from the ventilation pipe 3 to the upper part of the inner side of the greenhouse, mixes with the hot air above the inner side of the greenhouse and reduces the temperature. The air in the greenhouse enters the other end of the cooling air duct 5 under the action of suction and atmospheric pressure. In the process of air flowing from one end of the cooling air duct 5 to the other end, since the cooling air duct 5 is buried at the lower end of the drainage channel 2, heat exchange can be completed through the cooling air duct 5, thereby reducing the temperature of the air entering the fan 6, and the air in the drainage channel 2 When the temperature of water rises, the evaporation phenomenon will accelerate, and the evaporation phenomenon will absorb heat, thereby keeping the cooling air duct 5 able to cool down at all times. The water in the drainage channel 2 is always flowing due to the drainage of the drain pan 8, and the flowing water will replace the water body in contact with the cooling air duct 5, so that the cooling air duct 5 is always exchanging heat with the low-temperature water body, thereby maintaining the cooling efficiency and the cooling effect for a long time. The temperature in the greenhouse gradually decreases, and the temperature of the air entering the cooling air duct 5 will also decrease appropriately until the temperature in the greenhouse is adjusted to the set temperature. Then the air entering the cooling air duct 5 can be directly extracted from the outside, or the air can be directly transported from the outside to the greenhouse without passing through the cooling air duct 5.

[0032] A seedling raising rack 7 for raising seedlings is provided in the greenhouse main body 1. The seedling raising racks 7 are arranged in an array on both sides of the greenhouse, and the middle gap is a passage for the staff. The seedling raising rack 7 includes an arched frame 10, and a plurality of drain trays 8 arranged in a vertical array are provided in the arched frame 10. A detachable seedling raising tray 11 is clamped on the drain tray 8. The middle part of each drain tray 8 is horizontally rotated and connected to the seedling raising rack 7. The angle of the drain tray 8 relative to the ground on the seedling raising rack 7 is adjustable. Each drain tray 8 is open upward, and a plurality of longitudinally arranged guide grooves 15 are respectively provided at the lower end of the inner side surface of each drain tray 8. Transversely arranged drain grooves 12 are respectively provided at the front and rear ends of the drain tray 8. The water seeping from the seedling raising tray 11 will pass through the guide grooves 15 and enter the drain groove 12, and the outer side of the drain groove 12 is rotatably connected to the vertically arranged drain pipe 9. The water in the drain groove 12 will flow downward through the drain pipe 9 and finally be led to the drainage channel 2 for discharge, and each drain The grooves 12 are all arranged in parallel, and the drain pipes 9 are rotatably connected to the sides of each drain groove 12, so the drain grooves 12 are controlled to rise and fall, which can control each drain plate to maintain a certain inclination while maintaining parallelism. In order to make the seedlings more evenly illuminated and the watering humidity uniform, the drain plate is controlled to always maintain a certain inclination angle so that the water can flow out more conveniently, and the inclination angle of the drain tray 8 is periodically changed, that is, the drain tray 8 is initially kept horizontal, posture 1, the front end of the drain tray 8 is moved downward, so that each drain tray 8 is tilted toward the inside of the greenhouse, which assists in setting up fluorescent lamps in the greenhouse to improve the lighting efficiency, posture 2, the front end of the drain tray 8 moves upward, and the drain tray 8 is tilted to the outside of the greenhouse. At this time, the external light contacts the upper end of the breeding tray more evenly, and the two postures are switched periodically to avoid water accumulation and uneven humidity in a certain part during the watering process.

[0033] The seedling tray 11 is a square tray with an opening upward. The lower end of the seedling tray 11 is detachably connected to the upper end of the drain tray 8. A certain distance is maintained between the lower end of the seedling tray 11 and the drain tray 8 so that leaked water can flow out more conveniently. A plurality of seedling grilles 13 are provided in the seedling tray 11. The seedling grilles 13 divide the seedling tray 11 into a plurality of seedling areas, so that different seedlings can be cultivated in different areas, and it is more convenient to take out the seedlings. The lower end surface of the seedling tray 11 is provided with a plurality of water-permeable holes 14, which are sprayed in the seedling tray 11. The remaining water will flow downward from the water permeable holes 14 into the drain tray 8. When cultivating seedlings, gravel is filled in the seedling tray 11. The water permeability of the gravel can prevent the roots of the seedlings from drowning and the root system from breathing poorly. At the same time, the gaps in the gravel are conducive to the growth of the root system and can effectively increase the length of the seedling root system. At the same time, the bottom gravel layer is easier to separate when taking out the seedlings, avoiding root breakage when taking out the seedlings. A base layer is laid above the gravel layer for cultivating seedlings, and certain nutrients are added to the spraying water to supplement nutrients for the growth process of the seedlings.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
