Description

Technical Field

[0001] The utility model relates to a dripping prevention device for a flue-cured tobacco seedling raising shed, belonging to the technical field of flue-cured tobacco seedling raising sheds. Background Art

[0002] Tobacco seedling raising is one of the key links in flue-cured tobacco production. During the seedling raising period, the humidity in the seedling raising greenhouse is high. When the temperature in the seedling raising greenhouse rises and the temperature difference between the inside and outside is large, water vapor will be generated in the seedling raising greenhouse and rise to the top of the greenhouse film to form water droplets. Since the top of the greenhouse film is arc-shaped, the water droplets will roll to both sides. When the adhesion between the water droplets and the greenhouse film cannot withstand the gravity of the water droplets, the water droplets will drip. The falling water droplets have a strong impact force, splashing on the tobacco seedlings, which can easily cause damage to the tobacco seedlings. In severe cases, the matrix in the seedling tray will be flushed out. If there is too much water in the seedling tray, it is easy to cause the tobacco seedlings to die and seriously reduce the survival rate of the tobacco seedlings. Among them, the incidence of anthrax and damping-off caused by excessive humidity in the seedling tray is high. In actual situations, most of the water droplets drip mainly on both sides of the seedling raising greenhouse. Therefore, the damaged tobacco seedlings are mainly distributed on both sides of the greenhouse, while the tobacco seedlings in the middle are hardly affected by the falling water droplets.

[0003] Existing literature discloses a drip-proof flue-cured tobacco seedling greenhouse device (CN 217241711 U), comprising a greenhouse frame and a roof, wherein the roof is installed at the upper end of the greenhouse frame, and a water removal and drainage structure is installed at the lower end of the roof; the water removal and drainage structure comprises: a plurality of connecting rods, a drainage plate, two first water guide grooves, two second water guide grooves, a plurality of water guide pipes, a water storage box, a vibration component and an air blowing component; the water removal and drainage structure adopted in this case drains and collects water droplets falling from the upper end of the inner wall of the roof through a built-in conical drainage plate to prevent the dripping of water droplets from affecting the tobacco seedlings, and the adopted air blowing component can actively blow off the water droplets on the inner wall of the roof to reduce the water droplet content on the roof, and at the same time, the water droplets on the lower wall of the drainage plate can be collected and drained through the two second water guide grooves at the lower end of the drainage plate, and the flow rate of the water droplets on the upper end of the drainage plate can be increased through the built-in vibration component to prevent the water droplets on the lower wall of the drainage plate from dripping. However, the device still has the following problems: the position of the guide plate is fixed and its inclination angle cannot be adjusted, and thus the flow rate of the water droplets cannot be adjusted as needed; the vibration component is not effective, and it can cause water droplets to fall directly from the guide plate onto the tobacco seedlings and damage them. Utility Model Content

[0004] Based on the above, the utility model provides a drip prevention device for a flue-cured tobacco seedling raising shed, which overcomes the deficiencies of the prior art by adjusting the inclination angle of the drainage membrane.

[0005] The technical scheme of the utility model is: a drip-proof device for a flue-cured tobacco seedling shed, comprising a support frame and a shed roof, wherein the shed roof is installed at the upper end of the support frame, and a drip-proof mechanism is installed at the lower end of the shed roof, wherein the drip-proof mechanism comprises a lifting mechanism, a support rod, a drainage membrane, a first water guide groove, a second water guide groove and a water guide pipe;

One end of the drainage membrane is fixedly connected to the notch of the first water guide groove, and the other end of the drainage membrane can be movably arranged in the second water guide groove. The water guide pipe is vertically arranged at the bottom of both ends of the first water guide groove and the second water guide groove.

[0007] In one example, the second water guide groove includes an open groove, an inner water groove, an outer water groove, a rotating shaft and a driving source. The inner water groove and the outer water groove are respectively arranged on both sides of the groove opening of the open groove. The rotating shaft can be rotatably installed in the open groove, one end of the drainage membrane is wound around the rotating shaft, and the rotating shaft is connected to the driving source.

[0008] In one example, a sliding shaft is provided at the end of the inner water tank close to the outer water tank, and the drainage membrane passes through the outer end surface of the sliding shaft.

[0009] In one example, the interior of the support rod is hollow, and an air inlet is provided at one end thereof, and the air inlet is connected to the air source device through an air pipe. Two exhaust nozzles are provided on both sides of the support rod, and the air nozzles are inclined toward the surface of the drainage membrane.

[0010] In one example, the lifting mechanism is an electric cylinder, the base of the electric cylinder is installed on the roof, and both ends of the support rod are connected to the telescopic rod of the electric cylinder.

By installing an air nozzle on the support rod, the flow rate of the water droplets on the drainage membrane can be increased when necessary. It is particularly suitable for high humidity or large temperature difference environmental conditions, and can effectively respond to complex climate changes. BRIEF DESCRIPTION OF THE DRAWINGS

The second water guide groove 7 includes an open groove 71, an inner water groove 72, an outer water groove 73, a rotating shaft 74 and a driving source 75. The open groove 71 is a U-shaped groove. The inner water groove 72 and the outer water groove 73 are respectively installed at intervals on both sides of the notch of the open groove 71, and a sliding shaft 76 is provided at the end of the inner water groove 72 close to the outer water groove 73. The drainage membrane 5 passes through the outer end surface of the sliding shaft 76 and enters the open groove 71. The rotating shaft 74 is rotatably installed in the open groove 71 along the length direction. The end of the drainage membrane 5 is wound around the rotating shaft 74, and the rotating shaft 74 is connected to the driving source 75. The driving source 75 can be a driving motor. Drainage pipes are installed at the bottom of both ends of the first water guide groove 6 and the second water guide groove 7 to drain the water drops to the ground.

[0023] Furthermore, the interior of the support rod 4 is hollow, and an air inlet 9 is provided at one end thereof, which is connected to the air source device 12 through an air pipe 11. Two exhaust nozzles 10 are provided on both sides of the support rod 4, and the air nozzles 10 are inclined toward the surface of the drainage membrane 5. When it is necessary to increase the anti-drip effect of the greenhouse, the air source equipment 12 (such as a fan) can transport the gas in the greenhouse to the support rod 4, and spray it onto the drainage membrane 5 through the air nozzle 10, thereby increasing the flow rate of water droplets on the drainage membrane 5, and at the same time, to a certain extent, it can prevent water droplets on the drainage membrane 5 from falling from the middle and upper parts.

[0024] The working principle of the above-mentioned anti-drip device for flue-cured tobacco seedling shed is as follows:

[0025] When the sensor detects that the shed is in an environment with high humidity or large temperature difference, the driving source 75 drives the rotating shaft 74 to rotate and release the drainage membrane 5, and the lifting mechanism 3 drives the support rod 4 to move up a distance, so that the inclination of the drainage membrane 5 is greater. At this time, the water droplets on the drainage membrane 5 can quickly flow down to the first water guide groove 6 and the second water guide groove 7 at both ends. If necessary, the flow rate of the water droplets on the drainage membrane 5 can be increased by the air nozzle 10 to further improve the drainage effect. When the shed is in other normal environmental conditions, the drainage membrane 5 can be adjusted to be in a general tilted state. At this time, the water droplets slowly flow down on the drainage membrane 5, providing the water droplets with sufficient adhesion to prevent them from falling on the tobacco seedlings prematurely. In addition, the utility model can ensure that the drainage membrane 5 is always in a straight state during use through the cooperation of the lifting mechanism 3, the rotating shaft 74 and the driving source 75, thereby ensuring the drainage effect.
