[0021] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1-5 As shown, this embodiment discloses a wind-blown film tube. Soilless cultivated crops are located on planting racks that extend in a straight line. Multiple planting racks are arranged in the greenhouse, and the wind-blown film tube extends along the length of the planting racks. The wind-blown film tube is located below the planting racks. The wind-blown film tube of this embodiment includes an outer film tube 1, an inner film tube 2, and a tube cover 3. The outer film tube 1 and the inner film tube 2 are cylindrical. The inner film tube 2 is located inside the outer film tube 1. A gap is provided between the inner wall of the outer film tube 1 and the outer wall of the inner film tube 2. One end of the inner film tube 2 is connected to a fan, which can blow hot or cold air into the inner film tube 2.

[0023] The outer film cylinder 1 is provided with multiple first air outlets 11, which are arranged along the length of the outer film cylinder 1. The first air outlets 11 arranged along the length of the outer film cylinder 1 can send hot air or cold air outward along the length direction. There are multiple rows of first air outlets 11, which are symmetrically arranged on both sides of the outer film cylinder 1. Hot air or cold air can be output from both sides of the wind-blown film cylinder, thereby regulating the air temperature on both sides of the wind-blown film cylinder and providing a suitable temperature for the crops above.

[0024] The inner membrane cylinder 2 is provided with multiple second air outlets 21, which are arranged along the length of the inner membrane cylinder 2. The first air outlet 11 and the second air outlet 21 are staggered in the circumferential direction. The second air outlet 21 is located at the bottom row of the first air outlet 11, which is below the circumference of the inner membrane cylinder 2. The staggered arrangement of the second air outlet 21 and the first air outlet 11 allows the air entering the inner membrane cylinder 2 from the fan to enter the gap between the outer membrane cylinder 1 and the inner membrane cylinder 2 through the second air outlet 21, and then be sent out through the first air outlet 11. This can slow down the speed of the air being sent out of the inner membrane cylinder 2, so that the air sent out by the fan can fill the entire inner membrane cylinder 2, making the air temperature at both ends of the inner membrane cylinder 2 more uniform, and making the temperature of the air sent out by the first air outlet 11 in the length direction of the outer membrane cylinder 1 more uniform.

[0025] The inner membrane cylinder 2 is provided with multiple third air outlets 22, which are arranged along the length of the inner membrane cylinder 2. The third air outlets 22 are located below the second air outlets 21 in the circumferential direction of the inner membrane cylinder 2. The third air outlets 22 can deliver the air in the inner membrane cylinder 2 to the gap between the outer membrane cylinder 1 and the inner membrane cylinder 2, and deliver hot or cold air from the lower end of the inner membrane cylinder 2 to the second air outlets 21 and the first air outlets 11. This can expand the entire air membrane cylinder through airflow, keeping the gap between the outer membrane cylinder 1 and the inner membrane cylinder 2 unobstructed.

[0026] The other end of the inner membrane tube 2 is connected to the tube cover 3, and the other end of the outer membrane tube 1 is connected to the tube cover 3. The tube cover 3 includes a side plate 36, and the inner wall of the tube cover 3 is provided with multiple support plates 35. The multiple support plates 35 are arranged in a ring. Part of the inner membrane tube 2 is located between the side plate 36 and the support plates 35. The support plates 35 can support the end of the inner membrane tube 2. The outer membrane tube 1 is fixed to the side plate 36 by a fixing ring 37. The fixing ring 37 can be an elastic ring made of rubber, which can fix the outer membrane tube 1 on the tube cover 3.

[0027] The cylinder cover 3 is provided with multiple fourth air outlets 31, which connect the inner membrane cylinder 2 and the outside air. The multiple fourth air outlets 31 are arranged along the circumference of the cylinder cover 3. The cylinder cover 3 is equipped with a baffle 33, and the center of the cylinder cover 3 is provided with a hinge point 34. The baffle 33 is installed at the hinge point 34 and is fan-shaped. The baffle 33 can rotate around the hinge point 34 to completely block or completely move away from all the fourth air outlets 31. By rotating the baffle 33, the number of fourth air outlets 31 blocked by the baffle 33 can be controlled, thereby controlling the air volume of hot or cold air from the inner membrane cylinder 2 output from the fourth air outlets 31, and thus controlling the air speed of hot or cold air output from the first air outlet 11. When the baffle 33 completely moves away from all the fourth air outlets 31, the air speed output from the first air outlet 11 is the minimum. When the baffle 33 completely blocks all the fourth air outlets 31, the air speed output from the first air outlet 11 is the maximum.

[0028] The baffle 33 is located inside the cylinder cover 3. The cylinder cover 3 is provided with a sliding groove 32, which is arc-shaped. The baffle 33 is provided with a sliding rod 331, which passes through the sliding groove 32 and can slide along the sliding groove 32. The sliding rod 331 is a threaded rod, and a locking button 332 is installed on the sliding rod 331. The locking button 332 is connected to the sliding rod 331 by threads. The locking button 332 is located on the outside of the cylinder cover 3. When the locking button 332 is rotated and approaches the outer wall of the cylinder cover 3, the baffle 33 can be fixed. Loosening the locking button 332 can move the sliding rod 331 to rotate the baffle 33.

[0029] This embodiment also includes a support rope 4. Since there is no frame inside the wind-blown film tube for support, it is only supported by the air from the fan. The wind-blown film tube in this embodiment is lifted by a support rope 4 passing through the top of the inner film tube 2, which prevents the wind-blown film tube from collapsing and lying on the ground when there is no ventilation. The support rope 4 includes a main rope 41 and multiple fixing ropes 42. The main rope 41 extends along the length of the inner film tube 2, and the multiple fixing ropes 42 are arranged along the length of the main rope 41. The main rope 41 is located inside the inner film tube 2, and the fixing ropes 42 pass upward through the inner film tube 2 and the outer film tube 1. One of the fixing ropes 42 passes through the tube cover 3. The fixing rope 42 can be fixed to the fixing hook at the bottom of the planting frame above the wind-blown film tube, which can lift the top of the wind-blown film tube to facilitate the fan to deliver air.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
