Description

Technical Field

[0001] This utility model belongs to the field of greenhouse technology, specifically relating to a greenhouse with dual ventilation mode. Background Technology

[0002] In the field of agricultural planting, greenhouses are widely used. To ensure the healthy growth of crops in the greenhouse, good ventilation is essential. Therefore, in existing technologies, filter screens are usually installed at the ventilation points of the greenhouse. The purpose is to effectively block mosquitoes from entering the greenhouse and avoid damaging the crops, while also preventing dust from entering, maintaining a clean environment inside the greenhouse, and reducing the impact of dust on the physiological processes of crops such as photosynthesis.

[0003] However, these filtration devices currently have obvious defects. On the one hand, when dust or insects adhere to the filter screen, cleaning work faces many difficulties. The filter screens in some greenhouses need to be disassembled manually and then cleaned. This process not only consumes a lot of manpower, but also requires growers to invest a lot of time.

[0004] On the other hand, some filter screens that use mechanical structures for cleaning, while reducing the hassle of manual disassembly to some extent, are often quite complex. Once they malfunction, they are difficult to repair, which can cause the entire ventilation and filtration system to malfunction for a long time, affecting the growth environment of crops in the greenhouse.

[0005] Therefore, it is necessary to propose a new type of dual-ventilation greenhouse. Utility Model Content

[0006] The purpose of this invention is to provide a dual-ventilation mode planting greenhouse that can clean the filter screen, avoiding tedious disassembly, saving manpower and time, and optimizing the cleaning structure to reduce complexity and malfunctions.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A dual-ventilation greenhouse includes a greenhouse body, with multiple air ducts fixed on both sides of the greenhouse body. A fan is installed inside the air duct and close to the interior of the greenhouse body. A filter screen is movably connected to the air duct, and a drive mechanism for driving the filter screen to rotate is installed on the air duct.

[0009] The driving mechanism includes a rotating frame rotatably connected to one end of the air guide pipe. The rotating frame is located on the side of the air guide pipe away from the greenhouse body. The filter screen is mounted on the rotating frame. A ring gear is fixed on the outer side of the rotating frame. A second motor is installed on the outer side of the air guide pipe. A drive gear is fixed at the output end of the second motor, and the drive gear meshes with the ring gear.

[0010] Multiple counterweights are evenly distributed on the outer side of the filter screen.

[0011] A fixing rod is fixed at the center of one end of the filter screen. Multiple fixing plates are fixed inside the air guide tube. A fixing plate is fixed at one end of the multiple fixing plates that are close to each other. The fixing plate is slidably connected to the fixing rod. An abutment plate is fixed on the outside of the fixing rod. Multiple rotating abutment balls are fixed on the side of the abutment plate that is close to the fixing plate. At least one fixing ball is fixed on the side of the fixing plate that is close to the abutment plate, and the fixing ball abuts against the rotating abutment ball.

[0012] A rotating frame is rotatably connected to the outside of the fixed rod, and multiple springs are installed between the rotating frame and the fixed plate.

[0013] The fixed plate is fixed with a plurality of guide rods at one end near the rotating frame, and the plurality of guide rods are respectively inserted into a plurality of springs, and the plurality of guide rods are slidably connected to the rotating frame.

[0014] Threaded rods are rotatably connected inside the air duct and on both sides of the fan. Mounting blocks are fixed on both sides of the fan, and the two threaded rods are threadedly connected to the two mounting blocks respectively. The two threaded rods are connected by a transmission belt. A first motor is fixed inside the greenhouse body, and the output end of the first motor is connected to one of the threaded rods.

[0015] An abutment block is fixed near the top of the threaded rod, and the abutment block is located below the transmission belt.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention utilizes a second motor to drive the drive gear and ring gear to rotate, which in turn causes the filter screen to swing, thus vibrating and throwing away insects and dust on the filter screen. This avoids tedious disassembly, saves manpower and time, optimizes the cleaning structure, reduces complexity, reduces the occurrence of failures, lowers maintenance difficulty and cost, ensures the stable operation of the ventilation and filtration system, continuously creates a good growing environment for crops in the greenhouse, and improves planting efficiency and benefits.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-6 As shown, a dual-ventilation planting greenhouse includes a greenhouse body 1. Multiple air guide pipes 2 are fixed on both sides of the greenhouse body 1. Fans 3 are installed inside the air guide pipes 2 and close to the interior of the greenhouse body 1. A filter screen 10 is movably connected to the air guide pipes 2. The filter screen 10 can block mosquitoes and other insects outside the greenhouse body 1 and prevent them from entering the greenhouse body 1.

[0028] By setting up fan 3, fan 3 can be turned on for ventilation, or it can be turned off to allow the greenhouse body 1 to circulate air with the outside for ventilation, thus achieving a dual ventilation mode.

[0029] See attached document Figure 3 Inside the air duct 2, threaded rods 5 are rotatably connected to both sides of the fan 3. Mounting blocks 4 are fixed on both sides of the fan 3, and the two threaded rods 5 are threadedly connected to the two mounting blocks 4 respectively. The two threaded rods 5 are connected by a transmission belt 6. A transmission wheel can be set on the outside of the threaded rod 5, and then the transmission wheel and the transmission belt 6 are mutually transmitted to ensure the transmission effect of the transmission belt 6. A first motor 7 is fixed inside the greenhouse body 1, and the output end of the first motor 7 is connected to one of the threaded rods 5.

[0030] When it is necessary to move the fan 3 to prevent it from blocking the natural ventilation of the air duct 2, the first motor 7 can be driven so that the output end of the first motor 7 drives one of the threaded rods 5 to rotate. Through the setting of the transmission belt 6, the two threaded rods 5 are driven to rotate synchronously, thereby enabling the threaded connection between the threaded rod 5 and the mounting block 4. This allows the mounting block 4 to move the fan 3 from the mounting groove 16 upwards, exposing the air duct 2. The threaded rod 5 has an abutment block 8 fixed near the top, and the abutment block 8 is located below the transmission belt 6. The abutment block 8 can block the maximum movement of the mounting block 4, preventing the fan 3 from moving excessively and causing the fan 3 to come into contact with the transmission belt 6, thus damaging the transmission belt 6.

[0031] The air duct 2 is equipped with a drive mechanism for driving the filter screen 10 to rotate. Through the drive mechanism, the mosquitoes or dust adhering to the filter screen 10 can be shaken off.

[0032] See attached document Figure 4 The driving mechanism includes a rotating frame 9 rotatably connected to one end of the air duct 2. The rotating frame 9 is located on the side of the air duct 2 away from the greenhouse body 1. A filter screen 10 is mounted on the rotating frame 9. The filter screen 10 is a barrel-type filter structure. One end of the filter screen 10 is connected to the rotating frame 9, and the other end is in the air. A ring gear 12 is fixed on the outside of the rotating frame 9. A second motor 14 is installed on the outside of the air duct 2. The second motor 14, the first motor 7, and other electronic or mechanical components such as the ring gear 12 and the drive gear 13 can all be protected by protective covers. The output end of the second motor 14 is fixed with the drive gear 13, and the drive gear 13 is meshed with the ring gear 12.

[0033] Under normal circumstances, the end of the filter screen 10 is drooping. To shake off dust or insects adhering to the filter screen 10, the second motor 14 can be driven, causing the output of the second motor 14 to drive the drive gear 13 to rotate. Through the meshing connection between the drive gear 13 and the ring gear 12, the drive gear 13 can drive the ring gear 12 and the rotating frame 9 to rotate, and the rotating frame 9 can drive the filter screen 10 to rotate. This creates a centrifugal force when the filter screen 10 rotates, causing it to vibrate slightly and shake off the adhering objects. To ensure its effectiveness, multiple counterweights 11 are evenly arranged on the outer side of the filter screen 10. The counterweights 11 increase the vibration force when the filter screen 10 initially rotates, thereby increasing the vibration amplitude of the filter screen 10 and ensuring that the objects are shaken off.

[0034] Further, refer to the appendix. Figure 5 and attached Figure 6 A fixing rod 15 is fixed at the center of one end of the filter screen 10. Multiple fixing plates 18 are fixed inside the air duct 2. A fixing plate 19 is fixed at one end of the multiple fixing plates 18 that are close to each other. The fixing plate 19 is slidably connected to the fixing rod 15. An abutment plate 17 is fixed on the outside of the fixing rod 15. Multiple rotating abutment balls 21 are fixed on the side of the abutment plate 17 that is close to the fixing plate 19. At least one fixing ball 20 is fixed on the side of the fixing plate 19 that is close to the abutment plate 17, and the fixing ball 20 abuts against the rotating abutment ball 21.

[0035] When the filter screen 10 rotates, it drives the fixed rod 15 to rotate as well. The fixed rod 15 drives the abutment plate 17 and the rotating abutment ball 21 on it to rotate. The mutual abutment between the rotating abutment ball 21 and the fixed ball 20 causes the abutment plate 17 to drive the fixed rod 15 to move away from the fixed plate 19 and push the filter screen 10. The outer side of the fixed rod 15 is rotatably connected to the rotating frame 22. Multiple springs 23 are installed between the rotating frame 22 and the fixed plate 18. The springs 23 can drive the fixed rod 15 to return to its original position. The multiple rotating abutment balls 21 allow the fixed rod 15 to repeatedly push and abut the filter screen 10, resulting in a shaking effect and ensuring that the items on the filter screen 10 are shaken off.

[0036] Furthermore, a plurality of guide rods 24 are fixed to one end of the fixing plate 18 near the rotating frame 22, and the plurality of guide rods 24 are respectively inserted into a plurality of springs 23. The plurality of guide rods 24 are slidably connected to the rotating frame 22. Through the setting of the guide rods 24, the guide rods 24 can limit the rotating frame 22 to ensure that the rotating frame 22 will not shift or rotate, and can also limit the springs 23 to ensure that the springs 23 will not be skewed.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
