Description

Technical Field

[0001] The utility model belongs to the technical field of planting greenhouses, and in particular relates to an automatic ventilation greenhouse. Background Art

[0002] As a product of modern agricultural development, greenhouses have been widely popularized. The tops of existing greenhouses are covered with plastic film. Sunlight passes through the plastic film to provide sufficient sunlight to the plants in the greenhouse, ensuring the temperature and sunlight required for plant growth. Since the plastic film is sealed and covered on the frame of the greenhouse, the inside of the greenhouse is not ventilated, the humidity is high, and it is not conducive to the growth of plants. Therefore, the plastic film needs to be rolled up regularly to ventilate the greenhouse.

[0003] 1. A wireless automatic greenhouse film roll ventilation system disclosed in Chinese patent CN111480488U. In this system, the driving motor moves, driving the fourth bevel gear and the second ring gear to move, so that the fourth bevel gear is easily collided with the second bevel gear when meshing, and the second ring gear is easily collided with the first ring gear when meshing, which leads to a short life of the gear, frequent maintenance is required, and the practicality is poor.

[0004] 2. An automatic ventilation device for greenhouses disclosed in Chinese patent CN204860355U solves the problem that the current measures for greenhouse ventilation are all manually controlled opening and closing. The reel pulls the greenhouse plastic film to move. When the greenhouse plastic film is rolled up, it is easy to overlap, which will cause part of the film to sag and block the window, making it easy for the greenhouse to not be fully opened, resulting in poor ventilation effect of the greenhouse. Utility Model Content

[0005] The technical problem to be solved by the utility model is that collision is easy to occur when the fourth bevel gear is meshed with the second bevel gear and the second gear ring is meshed with the first gear ring, thereby resulting in a shorter life of the gears. In view of the deficiencies of the prior art, an automatic ventilation shed is provided.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0024] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0025] Example 1: See Figure 1-5 The present embodiment is an automatically ventilated greenhouse, which includes a support frame 10, a greenhouse 11 is arranged on the outside of the support frame 10, a double-headed motor 12 is fixedly installed inside the support frame 10, and a winding assembly 20 is arranged at one group of output ends of the double-headed motor 12, and the winding assembly 20 includes a winding wheel 28, and a winding rope 29 is arranged on the surface of the winding wheel 28. The winding assembly 20 drives the winding wheel 28 to rotate under the drive of the double-headed motor 20, and the winding rope 29 is wound around the winding wheel 28. One end of the winding rope 29 is connected to a film rolling assembly 30, and the winding wheel 28 rotates to make the winding rope 29 drive the film rolling assembly 30 to move, and a winding film 14 is arranged on the surface of the greenhouse 11, and one side of the winding film 14 is connected to the film rolling assembly 30. The film rolling assembly 30 moves to retract the winding film 14 into the film rolling assembly 30, and the greenhouse is opened to complete ventilation.

[0026] The winding assembly 20 also includes a first slanted plate 21, an electric push rod 22 and a winding shaft 23. The first slanted plate 21 is connected to one of the output ends of the double-headed motor 12. When the double-headed motor 12 is started, the double-headed motor 12 drives the first slanted plate 21 to rotate. The electric push rod 22 is fixedly mounted on the surface of the double-headed motor 12. The middle part of the winding shaft 23 is rotatably connected to the support frame 10. One end of the winding shaft 23 is fixedly mounted with a second slanted plate 24. The middle part of the output end of the electric push rod 22 is rotatably provided with a wheel 25. A layer of elastic material is provided on the surface of the wheel 25 to increase friction. The surfaces of the first slanted plate 21 and the second slanted plate 24 are provided with grooves for increasing friction. The electric push rod 22 is started, and the electric push rod 22 drives the wheel 25 to move. The wheel 25 is used to abut against the surfaces of the first slanted plate 21 and the second slanted plate 24. The wheel 25 squeezes the first slanted plate 21 and the second slanted plate 24 at the same time. The rotation of the first slanted plate 21 drives the wheel 25 to rotate through the friction force. The rotation of the wheel 25 drives the second slanted plate 24 to rotate through the friction force. The rotation of the second slanted plate 24 drives the winding shaft 23 to rotate. The rotation of the winding shaft 23 drives the winding wheel 28 to rotate. The winding assembly 20 also includes a locking assembly, which is used to prevent the film rolling assembly 30 from falling.

[0027] See also Figure 5When ventilation is completed and the greenhouse is re-covered, the locking assembly unlocks the film roll assembly 30. The film roll assembly 30 includes an outer shell 31, and a film roll shaft 32 is rotatably arranged inside the outer shell 31. When the film roll assembly falls, the winding film 14 rolled on the surface of the film roll shaft 32 is unfolded, causing the film roll shaft 32 to rotate. An energy storage assembly 40 is fixedly installed at one end of the outer shell 31, and one end of the film roll shaft 32 passes through the outer shell 31 and is connected to the energy storage assembly 40. The film roll shaft 32 rotates to store energy for the energy storage assembly 40.

[0028] See also Figure 5 The energy storage assembly 40 includes an energy storage shell 41, which is threadedly connected to one end of the outer shell 31. A volute spring 42 is fixedly installed inside the energy storage shell 41. When the film assembly 30 falls, gravity and the unfolding of the winding film 14 are used to drive the film shaft 32 to rotate. A connecting sleeve 43 is fixedly installed on one end of the volute spring 42. The connecting sleeve 43 is sleeved with one end of the film shaft 32. The rotation of the film shaft 32 drives the connecting sleeve 43 to rotate, and the rotation of the connecting sleeve 43 causes the volute spring 42 to store energy.

[0029] See also Figure 3-4 A support frame 50 is fixedly installed on the surface of the support frame 10, and a support shaft 51 is fixedly installed on one side of the support frame 50. The support frame 50 supports the winding rope 29 to make the winding rope 29 away from the greenhouse. A guide wheel 52 is rotatably provided on the surface of the support shaft 51. The guide wheel 52 is slidably connected to the middle part of the winding rope 29. The winding rope 29 contacts and slides with the guide wheel 52 to avoid friction between the winding rope 29 and the greenhouse, thereby avoiding wear of the winding rope 29 or the greenhouse.

[0030] See also Figure 2-3 The support frame 10 includes a side frame 15, a diagonal support frame 16 is fixedly connected to the top of the side frame 15, one end and the middle of the diagonal support frame 16 are fixedly connected to a cross frame 17, the double-headed motor 12 and the electric push rod 22 are fixedly installed with the cross frame 17 at the lower position, and the winding shaft 23 is rotatably connected to the cross frame 17 at the upper position. The side frame 15, the diagonal support frame 16 and the cross frame 17 support the greenhouse 11, and the two groups of cross frames 17 support the motor 12 and the winding assembly 20.

[0031] See also Figure 2-3 The top of the side frame 15 is fixedly connected with an arc support frame 18, and the greenhouse 11 is fixedly installed on the surface of the arc support frame 18. The arc frame 18 supports the top of the greenhouse 11 into an arc shape, which makes the shape beautiful and convenient for receiving sunlight. At the same time, the winding film 14 is pulled by the gravity of the winding film assembly to fit the support frame 10 to prevent air leakage in the greenhouse.

[0032] Beneficial effects:

[0033] 1. Start the double-headed motor 12, which drives the first slant plate 21 to rotate, and start the electric push rod 22. The electric push rod 22 drives the wheel 25 to move, so that the wheel 25 squeezes the first slant plate 21 and the second slant plate 24 at the same time. At this time, the first slant plate 21 rotates and drives the wheel 25 to rotate through friction. The wheel 25 rotates and drives the second slant plate 24 to rotate through friction. The second slant plate 24 rotates and drives the winding shaft 23 to rotate. The winding shaft 23 rotates and drives the winding wheel 28 to rotate. The winding wheel 28 rotates to make the winding rope 29 rotate. The film rolling assembly 30 is driven to move, and then the film rolling assembly 30 drives the winding film 14 to roll up, and the greenhouse is opened to complete ventilation. In the device, the first inclined plate 21 and the second inclined plate 24 are squeezed by the wheel 25 to complete the linkage, and the first inclined plate 21 rotates to drive the wheel 25 to rotate, and then drives the second inclined plate 24 to rotate. When the wheel 25 squeezes the first inclined plate 21 and the second inclined plate 24 are connected, it is not easy to collide, which greatly reduces wear and tear, avoids reducing the life of the winding assembly 20, does not need frequent maintenance, and is more practical.

[0034] 2. The winding rope 29 drives the film rolling assembly 30 to move. When the film rolling assembly 30 moves, the torsional force is released through the energy storage assembly 40. When the energy storage assembly 40 releases the torsional force, the volute spring 42 drives the connecting shaft sleeve 43 to rotate. The rotation of the connecting shaft sleeve 43 drives the film rolling shaft 32 to rotate, and the winding film 14 is rolled on the surface of the film rolling shaft 32 to avoid overlapping when the winding film 14 is rolled up, so that the window is fully opened, and the ventilation effect of the greenhouse is better.

[0035] Embodiment 2: Embodiment 2 is a further improvement made on the basis of Embodiment 1, see Figure 2-4 In this embodiment of an automatic ventilation greenhouse, the locking assembly includes a locking piece 26 fixedly mounted on the output end of the electric push rod 22, and a locking disk 27 is fixedly mounted on the surface of the winding shaft 23 near the middle, and the locking piece 26 is used to abut against the surface of the locking disk 27.

[0036] Beneficial effect: when rapid cooling is required, the electric push rod 22 is started, which drives the push rod 22 to drive the wheel 25 and the locking plate 26 to move. The wheel 25 moves to separate the first inclined plate 21 and the second inclined plate 24. At the same time, the locking plate 26 squeezes the locking plate 27 to fix the locking plate 27, thereby stopping the rotation of the winding shaft 23 and fixing the winding wheel 28 to prevent the film rolling assembly 20 from pulling the winding rope 29 to fall under the influence of gravity, so that the greenhouse remains in an open state. At this time, the double-headed motor drives the fan 13 to rotate, increase the air flow, and complete rapid cooling.
