Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, and in particular to a ventilation device for tomato greenhouses. Background Technology

[0002] Ventilation systems for tomato greenhouses are designed to provide good ventilation and airflow in a greenhouse environment. Tomatoes are temperature-sensitive crops, requiring suitable temperature and humidity conditions for growth. Ventilation systems play a crucial role in tomato greenhouses, helping to control temperature, humidity, and carbon dioxide concentration, thereby providing an excellent growing environment and promoting tomato growth and yield.

[0003] A ventilation device for tomato greenhouses is disclosed in publication number "CN220606754U". The device includes a support mechanism with a ventilation mechanism at its top. The ventilation mechanism includes a support block with a groove in the center of its top. A connecting arm is fixedly mounted on the bottom outer side of the support block. A gear is rotatably connected to the bottom of the connecting arm, and several pin slots are formed on the outer wall of the gear. A movable pin is slidably connected to the bottom of the connecting arm near the gear, with one end passing through the connecting arm and slidably connected to the inner wall of the pin slot. The support mechanism includes a base with symmetrically connected outer support frames on both sides of its top. A slide rail is fixedly mounted on the inner side of the outer support frame, and the outer walls of both slide rails are slidably connected to the inner walls of the grooves in the support block. An internal fan is fixed to the support block and can slide on the slide rail surface, thereby adjusting the ventilation position.

[0004] While this patent allows for the adjustment of ventilation positions and prevents mosquitoes from entering the greenhouse, the ventilation positions within the greenhouse need to be changed multiple times depending on the different conditions inside. This process is cumbersome and inefficient. Furthermore, the patent requires the bellows to be flipped open and closed during ventilation to ensure smooth airflow. However, existing greenhouses are generally quite tall, making it difficult to flip and open the bellows, which also affects ventilation efficiency. Therefore, improvements are needed.

[0059] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a ventilation device for tomato greenhouses.

[0060] A ventilation device for tomato greenhouses includes a support plate 1 and a support frame 2, with the support frame 2 fixedly connected to the support plate 1; it also includes: a ventilation box 3, mounted on the support frame 2 and fixedly connected to the support frame 2; a ventilation pipe 4, mounted on the ventilation box 3 and fixedly connected to the ventilation box 3; a filter plate 5, mounted inside the ventilation box 3 and fixedly connected to the ventilation box 3; an adjustment mechanism mounted on the support plate 1 for adjusting the position of the ventilation device; and an opening and closing mechanism mounted on the ventilation box 3 for opening and closing the ventilation box 3.

[0061] Reference Figure 1 and Figure 4In a preferred embodiment, the adjustment mechanism includes: an adjustment frame 6, disposed on a support plate 1 and fixedly connected to the support plate 1; multiple adjustment plates 7, evenly disposed on the adjustment frame 6 and fixedly connected to the adjustment frame 6; an adjustment frame 8, disposed on the adjustment plates 7 and fixedly connected to the adjustment plates 7; an adjustment motor 9, fixedly connected to the adjustment frame 8; an adjustment shaft 10, detachably fixedly connected to the output end of the adjustment motor 9; an adjustment gear 11, fixedly connected to the adjustment shaft 10; and a sliding component disposed on the adjustment frame 6.

[0062] This configuration ensures that when the regulating motor 9 is running, it drives the regulating shaft 10, which is detachably and fixedly connected to the output end of the regulating motor 9, to rotate, thereby causing the regulating gear 11, which is fixedly connected to the regulating shaft 10, to rotate and provide power for the operation of the sliding component.

[0063] Reference Figure 4 In a preferred embodiment, the sliding component includes: a sliding groove 12, which is formed on the adjusting frame 6; a sliding rack 13, which is disposed in the sliding groove 12 and is slidably connected to the sliding groove 12; a fan 14, which is provided in multiples and the multiple fans 14 are evenly disposed on the sliding rack 13 and are fixedly connected to the sliding rack 13; and a connecting pipe 15, which is fixedly connected to the fan 14.

[0064] This configuration allows the sliding rack 13, which meshes with the adjusting gear 11, to slide within the sliding groove 12, thereby moving the fan 14, which is fixedly connected to the sliding rack 13, and thus enabling the fan 14 to be moved.

[0065] Reference Figure 5 In a preferred embodiment, the opening and closing mechanism includes: an opening and closing cylinder 16, which is disposed on the ventilation box 3 and fixedly connected to the ventilation box 3; an opening and closing rod 17, which is slidably connected to the opening and closing cylinder 16; an opening and closing block 18, which is disposed on the ventilation box 3 and fixedly connected to the ventilation box 3; an opening and closing groove 19, which is formed on the opening and closing block 18; an opening and closing tooth block 20, which is slidably connected to the opening and closing groove 19 and fixedly connected to the opening and closing rod 17; and a rotating component, which is disposed on the ventilation box 3.

[0066] This configuration allows the opening and closing cylinder 16 to move the opening and closing rod 17, which is slidably connected to the opening and closing cylinder 16, towards the direction of the opening and closing cylinder 16. This causes the opening and closing tooth block 20, which is fixedly connected to the opening and closing rod 17, to slide within the opening and closing groove 19, thereby driving the rotating component to operate.

[0067] Reference Figure 1 , Figure 2 and Figure 5In a preferred embodiment, the rotating component includes: a first rotating shaft 21, disposed inside the ventilation box 3 and fixedly connected to the ventilation box 3; a rotating plate 22, rotatably connected to the first rotating shaft 21; a rotating gear 23, fixedly connected to the rotating plate 22 and meshing with the opening and closing gear block 20; a second rotating shaft 24, rotatably connected to the rotating plate 22; an opening and closing plate 25, fixedly connected to the second rotating shaft 24; and a connecting component disposed on the ventilation box 3.

[0068] This configuration causes the rotating gear 23, which meshes with the opening and closing gear block 20, to rotate on the first rotating shaft 21, causing the rotating plate 22, which is fixedly connected to the rotating gear 23, to rotate around the axis of the first rotating shaft 21, thereby driving the opening and closing plate 25, which is fixedly connected to the second rotating shaft 24, to rotate around the axis of the first rotating shaft 21, thus enabling the connecting components to operate.

[0069] Reference Figure 5 In a preferred embodiment, the connecting components include: a first connecting shaft 26, which is disposed on the ventilation box 3 and fixedly connected to the ventilation box 3; a connecting plate 27, which is rotatably connected to the first connecting shaft 26; and a second connecting shaft 28, which is rotatably connected to the connecting plate 27 and fixedly connected to the opening and closing plate 25.

[0070] This configuration allows the second connecting shaft 28, which is fixedly connected to the opening and closing plate 25, to drive the connecting plate 27 to rotate around the axis of the first connecting shaft 26, thereby opening the ventilation box 3 and enabling the ventilation box 3 to be opened and closed.

[0071] Working principle: In use, first use a flexible hose to connect the connecting pipe 15, which is fixedly connected to the fan 14, to the ventilation pipe 4, which is fixedly connected to the ventilation box 3. Then start the regulating motor 9, which drives the regulating shaft 10, which is detachably fixedly connected to the output end of the regulating motor 9, to rotate. This causes the regulating gear 11, which is fixedly connected to the regulating shaft 10, to rotate, thereby driving the sliding rack 13, which meshes with the regulating gear 11, to slide in the sliding groove 12. This causes the fan 14, which is fixedly connected to the sliding rack 13, to move, thereby moving the position of the fan 14.

[0072] When the fan 14 is turned on, the opening and closing cylinder 16 is activated simultaneously, causing the opening and closing rod 17, which is slidably connected to the opening and closing cylinder 16, to move closer to the opening and closing cylinder 16. This causes the opening and closing tooth block 20, which is fixedly connected to the opening and closing rod 17, to slide in the opening and closing groove 19. This causes the rotating gear 23, which meshes with the opening and closing tooth block 20, to rotate on the first rotating shaft 21. This causes the rotating plate 22, which is fixedly connected to the rotating gear 23, to rotate around the axis of the first rotating shaft 21. This causes the opening and closing plate 25, which is fixedly connected to the second rotating shaft 24, to rotate around the axis of the first rotating shaft 21. This causes the second connecting shaft 28, which is fixedly connected to the opening and closing plate 25, to drive the connecting plate 27 to rotate around the axis of the first connecting shaft 26. This causes the ventilation box 3 to be opened, thus realizing the opening and closing of the ventilation box 3.

[0073] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
