Description

Technical Field

[0001] This utility model relates to the field of rice planting shed technology, and in particular to a rice planting shed with a ventilation and circulation structure. Background Technology

[0002] Rice cultivation sheds are a type of facility agriculture technology used for rice seedling raising or the entire cultivation process. They are primarily used to control the growing environment, increase yield, or cope with adverse climatic conditions. The main types include seedling sheds, used for cultivating seedlings in early spring when temperatures are low, ensuring robust growth before transplanting. These are mostly plastic greenhouses covered with transparent film and can be equipped with insulation blankets or ventilation equipment to shorten the field growth cycle and reduce the risk of seedling rot. Full-process cultivation sheds complete the entire process from seedling raising to maturity within the shed. These are suitable for high-value-added rice varieties (such as organic rice and functional rice) and are equipped with temperature control, lighting, and water and fertilizer systems.

[0003] In existing rice planting greenhouses, ventilation is typically achieved by simply opening the greenhouse doors and curtains. This method allows dust and other debris to enter the greenhouse and can also attract pests, making it inconvenient to use. Therefore, we propose a rice planting greenhouse with a ventilation and circulation structure to address these issues. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, when ventilating the inside of rice planting sheds, the doors and curtains of the sheds are usually opened directly. This ventilation method easily allows dust and other debris from the outside to enter the rice planting shed, and it also easily allows pests to enter the rice planting shed, making it inconvenient to use. Therefore, this utility model proposes a rice planting shed with a ventilation circulation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rice planting shed with a ventilation and circulation structure, including

[0007] The planter includes a planting shed, a fan, a limiting frame, a filter plate, an exhaust fan, a fixing plate, and insert plates. The fan is fixedly connected to the front side of the planting shed, and the exhaust fan is fixedly connected to the rear side of the planting shed. The planting shed, the fan, and the exhaust fan are connected in communication. The limiting frame is fixedly connected to the front side of the fan. The filter plate is slidably connected inside the limiting frame, and the left side of the filter plate extends to the outside of the limiting frame. There are two fixing plates and two insert plates. The two fixing plates are symmetrically slidably connected to the front side of the planting shed, and the two insert plates are fixedly connected to the sides of the two fixing plates that are close to each other. The top and bottom of the filter plate are provided with slots, and the two insert plates engage with the corresponding slots.

[0008] A fixing component is connected to a fixing plate and is used to fix the filter plate.

[0009] As a preferred embodiment of this utility model, the fixing component includes: an unlocking rod, an unlocking plate, two connecting rods, and two sliding brackets;

[0010] The unlocking rod is rotatably connected to the right side of the limiting frame, the unlocking plate is slidably connected to the rear side of the unlocking rod, two connecting rods are symmetrically rotatably connected to the front side of the unlocking plate, two sliding brackets are symmetrically slidably connected to the right side of the limiting frame, the front side of the two sliding brackets is rotatably connected to the rear side of the corresponding connecting rod, and the side of the two sliding brackets that is far apart from each other is fixedly connected to the side of the two fixed plates that is close to each other.

[0011] As a preferred embodiment of this utility model, a storage spring is fixedly connected to the right side of the limiting frame, and the right side of the storage spring is fixedly connected to the left side of the unlocking plate.

[0012] As a preferred embodiment of this utility model, the right side of the limiting frame is symmetrically and fixedly connected with guide plates, and there are two guide plates, with two sliding frames passing through the corresponding guide plates.

[0013] As a preferred embodiment of this utility model, a limiting plate is fixedly connected to the right side of both guide plates, and the left side of the two limiting plates is in movable contact with the right side of the unlocking plate.

[0014] As a preferred embodiment of this utility model, the limiting frame is a hollow structure, and two through holes are provided at the top and bottom of the limiting frame. The inner walls of the two through holes are in movable contact with the outer walls of the corresponding insert plates.

[0015] Beneficial effects:

[0016] 1. The combination of the fan and exhaust fan facilitates ventilation of the planting shed. The filter plate effectively intercepts and filters dust and impurities in the air entering the planting shed. The fixing components facilitate the movement of the fixing plate, which in turn moves the insert plate. The combination of the insert plate and the slot facilitates the fixing of the filter plate.

[0017] 2. Rotating the unlocking lever will push the unlocking plate to the right. At this time, the unlocking plate will slide until the right side contacts the limit plate. Simultaneously, the movement of the unlocking plate will pull the two connecting rods. The movement of the connecting rods will pull the two sliding frames to move away from each other. The movement of the sliding frames will drive the fixed plate to move. The movement of the fixed plate will drive the insertion plate to move. At this time, the insertion plate will disengage from the slot, thereby unlocking the filter plate.

[0018] This invention facilitates ventilation of the planting shed through the combination of a fan and an exhaust fan.

[0027] The planter 1, fan 2, limiting frame 3, filter plate 4, exhaust fan 5, fixing plate 13 and insert plate 14 are connected. The fan 2 is fixedly connected to the front side of the planter 1, the exhaust fan 5 is fixedly connected to the rear side of the planter 1, and the planter 1, fan 2 and exhaust fan 5 are connected. The limiting frame 3 is fixedly connected to the front side of the fan 2. The filter plate 4 is slidably connected to the inside of the limiting frame 3, and the left side of the filter plate 4 extends to the outside of the limiting frame 3. There are two fixing plates 13 and two insert plates 14. The two fixing plates 13 are symmetrically slidably connected to the front side of the planter 1, and the two insert plates 14 are respectively fixedly connected to the side of the two fixing plates 13 that are close to each other. The top and bottom of the filter plate 4 are provided with slots, and the two insert plates 14 are engaged with the corresponding slots.

[0028] The fixing component is connected to the fixing plate 13 and is used to fix the filter plate 4.

[0029] Through the above-mentioned mechanisms: the cooperation of the fan 2 and the exhaust fan 5 facilitates ventilation of the planting shed 1; the filter plate 4 facilitates the interception and filtration of dust and impurities in the air entering the planting shed 1; the fixing component facilitates the movement of the fixing plate 13; the movement of the fixing plate 13 will drive the movement of the insertion plate 14; the cooperation between the insertion plate 14 and the slot facilitates the fixing of the filter plate 4.

[0030] As a preferred embodiment of the present invention, the fixing component includes: an unlocking rod 6, an unlocking plate 7, two connecting rods 9 and two sliding brackets 10;

[0031] The unlocking rod 6 is rotatably connected to the right side of the limiting frame 3, the unlocking plate 7 is slidably connected to the rear side of the unlocking rod 6, the two connecting rods 9 are symmetrically rotatably connected to the front side of the unlocking plate 7, and the two sliding brackets 10 are symmetrically slidably connected to the right side of the limiting frame 3. The front side of the two sliding brackets 10 is rotatably connected to the rear side of the corresponding connecting rod 9, and the two sliding brackets 10 are respectively fixedly connected to the two fixed plates 13 on the side closer to each other. The rotation of the unlocking rod 6 will push the unlocking plate 7 to the right. At this time, the unlocking plate 7 slides until the right side contacts the limiting plate 12. At the same time, the movement of the unlocking plate 7 will pull the two connecting rods 9. The movement of the connecting rods 9 will pull the two sliding brackets 10 to the side further away from each other. The movement of the sliding brackets 10 will drive the fixed plate 13 to move. The movement of the fixed plate 13 will drive the insertion plate 14 to move. At this time, the insertion plate 14 will disengage from the slot, thereby unlocking the filter plate 4.

[0032] As a preferred embodiment of this utility model, a storage spring 8 is fixedly connected to the right side of the limiting frame 3. The right side of the storage spring 8 is fixedly connected to the left side of the unlocking plate 7. The elastic force of the storage spring 8 facilitates the lateral movement and reset of the unlocking plate 7.

[0033] As a preferred embodiment of this utility model, guide plates 11 are symmetrically fixedly connected to the right side of the limiting frame 3, and there are two guide plates 11. The two sliding frames 10 pass through the corresponding guide plates 11. The guide plates 11 can limit the sliding frames 10 so that the sliding frames 10 can only move vertically.

[0034] As a preferred embodiment of this utility model, a limiting plate 12 is fixedly connected to the right side of each of the two guide plates 11, and the left side of the two limiting plates 12 is in movable contact with the right side of the unlocking plate 7. The limiting plate 12 facilitates the limiting of the unlocking plate 7, thereby limiting the movement distance of the unlocking plate 7.

[0035] As a preferred embodiment of this utility model, the limiting frame 3 is a hollow structure. The top and bottom of the limiting frame 3 are provided with two through holes. The inner walls of the two through holes are in movable contact with the outer walls of the corresponding insert plates 14. The through holes facilitate the insert plates 14 to pass through the limiting frame 3, thereby allowing the insert plates 14 to engage with the slots.

[0036] It should be noted that the specific models of planting shed 1, fan 2, filter plate 4 and exhaust fan 5 used should be selected by those skilled in the art. Furthermore, the above-mentioned planting shed 1, fan 2, filter plate 4 and exhaust fan 5 are all existing technologies, and this solution will not elaborate on them.

[0037] The working principle of this utility model is as follows: In actual use, the fan 2 and the exhaust fan 5 are powered by an external power source. When the fan 2 and the exhaust fan 5 are started, the fan 2 draws outside air into the planting shed 1. The filter plate 4 intercepts and filters dust and other impurities in the air entering the planting shed 1, allowing fresh air to enter. The exhaust fan 5 then exhausts the air from the planting shed 1, achieving ventilation. When the filter plate 4 becomes clogged after prolonged use, the unlocking rod 6 is first pushed to rotate. When the unlocking rod 6 rotates, it pushes the unlocking plate 7 to the right. At this time, the unlocking plate 7 slides until its right side contacts the limiting plate 12. Simultaneously, the movement of the unlocking plate 7 pulls the two connecting rods 9. The movement of the connecting rods 9 then pulls the two sliding frames 10 to one side away from each other. The movement of the sliding frame 10 will cause the fixed plate 13 to move, which in turn will cause the insert plate 14 to move. At this point, the insert plate 14 will disengage from the slot, thus unlocking the filter plate 4. The filter plate 4 can then be pulled out for replacement or cleaning. When the filter plate 4 needs to be installed, first insert the filter plate 4 into the limiting frame 3, and then align the slot with the insert plate 14. Then push the unlocking rod 6 to rotate and reset. At the same time, the storage spring 8 will be released and pull the unlocking plate 7 to move to the left and reset. The reset of the unlocking plate 7 will push the two connecting rods 9, thereby causing the two sliding frames 10 to move closer to each other. The movement of the sliding frame 10 will cause the fixed plate 13 to reset, which in turn will cause the insert plate 14 to reset. At this point, the insert plate 14 will engage with the slot to fix the filter plate 4, completing the replacement of the filter plate 4.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
