Description

Technical Field

[0001] This utility model relates to the field of agricultural facilities technology, specifically to an automatic film rolling device for fruit tree greenhouses. Background Technology

[0002] In fruit tree facility cultivation, greenhouses are common protected cultivation facilities that can effectively regulate the environmental conditions for fruit tree growth. Ventilation is an important aspect of greenhouse management. Traditional ventilation methods mostly rely on manual film rolling, which is not only time-consuming and labor-intensive but also inefficient. In recent years, with the development of agricultural automation technology, automated film rolling machines have gradually become an important tool in greenhouse management.

[0003] Existing automatic film rolling machines generally rely on a motor to drive a drum shaft to rotate and roll up the insulation film. However, when unfolding the rolled-up insulation film, insufficient pre-tension can easily cause wrinkles in the film, resulting in incomplete unfolding and affecting the insulation effect of the greenhouse. In addition, after the insulation film is fully rolled up, the fruit trees are completely exposed to the external environment, making them susceptible to damage from mosquitoes and birds. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides an automatic film rolling device for fruit tree greenhouses, which solves the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic film-rolling device for fruit tree greenhouses is provided, comprising an arc-shaped greenhouse roof frame, two drive shafts for rolling up the insulation film at the top of the roof frame, and the two drive shafts are respectively connected to two motors, both of which are electrically connected to a controller. Rollers for rolling up insect-proof netting are provided on both sides of the roof frame. The front ends of the insulation film on the two drive shafts are respectively connected to one side of two connecting rods, and the front ends of the insect-proof netting on the two rolls are respectively connected to the other side of the two connecting rods. Arched tracks are provided at both ends of the roof frame, and the two ends of the two connecting rods are slidably mounted on the two arched tracks.

[0007] Furthermore, counterweights are provided at both ends of the connecting rod, and the two counterweights at both ends are slidably mounted on the two arched tracks.

[0008] Furthermore, contact sensors electrically connected to the controller are installed at the top and both ends of the arched track.

[0009] Furthermore, a protective cover is provided above the two drive shafts, and a wind speed sensor electrically connected to the controller is provided on the top of the protective cover.

[0010] Furthermore, the two sides of the canopy frame are fixed to the canopy wall, and temperature and humidity sensors that are electrically connected to the controller are installed inside the canopy wall.

[0011] Furthermore, a torque sensor electrically connected to the controller is installed on the coupling between the drive shaft and the motor.

[0012] Furthermore, a spring is provided inside the spool to facilitate automatic winding of the spool.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This solution uses a motor to drive the insulation film and insect net to automatically roll up and unroll. When the insulation film rolls up, the insect net can automatically unroll; when the insulation film unrolls, the insect net can automatically roll up. This achieves the needs of greenhouse insulation, ventilation, and insect protection. It has a high degree of automation and is easy to operate, thereby improving work efficiency and reducing the labor intensity of manual operation.

[0015] 2. This solution uses a connecting rod and counterweight design to maintain a certain pre-tension during the unfolding process of the insulation film, avoiding wrinkles caused by insufficient pre-tension and ensuring that the insulation film unfolds flat, thereby guaranteeing the insulation effect of the greenhouse; the spring-loaded mechanism enables the insect-proof net to automatically rewind when the insulation film is unfolded.

[0016] 3. This solution uses temperature and humidity sensors to monitor the environmental conditions inside the greenhouse in real time, and the controller automatically adjusts the unfolding and rewinding of the insulation film and insect-proof netting to ensure suitable temperature and humidity inside the greenhouse; the wind speed sensor can monitor the wind speed data outside the greenhouse in real time, and when the wind speed reaches the preset value, the controller can automatically unfold the insulation film to prevent strong winds from damaging the fruit trees.

[0017] 4. This solution uses a torque sensor to monitor the torque changes of the drive shaft in real time. When the torque is abnormal, the controller can automatically stop the motor to prevent the insulation film from being torn or damaged. The contact sensor can detect the automatic winding and unwinding of the insulation film and insect net, thereby improving the safety and reliability of the winding and unwinding process of the insulation film and insect net.

When the wind speed reaches the preset value, the controller can automatically unfold the insulation film 2 to prevent strong winds from damaging the fruit trees.

[0027] As an optional implementation, the two sides of the greenhouse roof frame 1 are fixed to the greenhouse wall 13. The greenhouse wall 13 is equipped with a temperature and humidity sensor 14 that is electrically connected to the controller.

[0028] As an optional implementation, a torque sensor 15 electrically connected to the controller is provided on the coupling between the drive shaft 3 and the motor 4.
