Description

Technical Field

[0001] This utility model provides a seedling protection frame for greenhouse chili pepper cultivation, belonging to the field of chili pepper cultivation and seedling technology. Background Technology

[0002] Chili peppers, a widely cultivated and important economic crop in my country, rely heavily on robust seedling cultivation for high yields and quality. The seedling stage has extremely demanding environmental requirements, necessitating suitable temperature, light, and water and fertilizer conditions within a greenhouse. Traditional seedling cultivation methods typically involve sowing seeds in centralized seedbeds or seed trays. However, with the development of large-scale, precision farming, specialized three-dimensional seedling racks for greenhouses have emerged.

[0003] However, pest and disease control is crucial during seedling cultivation, typically requiring regular pesticide spraying. Currently, spraying pesticides on vertical seedling racks presents significant challenges. Manual hand-held spraying is inefficient, exposes operators to pesticides, and poses a health threat. Therefore, the industry tends to fix spray booms or nozzles above the planting racks. However, this approach introduces a new problem: the fixed spraying device blocks sunlight for extended periods during the day, creating shadows on the seedling racks and severely impacting the photosynthesis required by chili seedlings, leading to excessive vegetative growth and weak seedlings, ultimately reducing seedling quality. Therefore, there is an urgent need for a seedling protection device that can achieve efficient and uniform pesticide application while completely avoiding sunlight during non-operational periods, thus preserving the normal growth of seedlings. Utility Model Content

[0004] The technical problem this invention aims to solve is that while directly installing a spray bar or nozzle above the planting rack facilitates pesticide spraying, it creates shadows inside the planting rack, affecting the photosynthesis of seedlings.

[0005] In order to solve the above problems, the technical solution proposed by this utility model is as follows: a seedling protection frame for planting peppers in a greenhouse, including a support base, support plates, and a planting frame; two support plates are fixedly set on the support base, the planting frame is fixedly connected between the two support plates, and a planting trough for planting peppers is opened in the planting frame; A rotating frame is rotatably connected to the bottom of the planting frame, and a protective frame is installed inside the rotating frame that can rotate to the top of the planting frame. The protective frame, which covers and insulates the planting frame, has an opening facing upwards, and several nozzles are installed at the bottom of the protective frame to spray pesticides onto the peppers in the planting trough. A limiting mechanism is provided on the support plate to fix the rotating frame in place before and after rotation. A fixing cylinder is fixedly installed inside the rotating frame, and a lifting and adjusting mechanism is provided inside the fixing cylinder to drive the protective frame to slide up and down within the rotating frame.

[0006] As an improvement, the planting frame is fixedly connected to both sides with fixed rods, and the fixed rods are fixedly connected to the support plate; the rotating frame is fixedly connected to a rotating plate that is rotatably sleeved on the fixed rods.

[0007] As an improvement, the shape and size of the protective frame correspond to the shape and size of the planting frame, and there is a gap between the protective frame, the rotating frame and the planting frame.

[0008] As an improvement, the rotating plate is provided with insertion holes; the limiting mechanism consists of two limiting screws, which are arranged vertically on the same support plate; both limiting screws, which can be inserted into the insertion holes to limit and fix the rotating plate before and after rotation, are threadedly connected to the support plate.

[0009] As an improvement, the lifting adjustment mechanism includes an adjusting screw, a connecting rod, and a lifting plate; the adjusting screw is rotatably disposed inside a fixed cylinder, and the lifting plate located inside the fixed cylinder is threadedly connected to the adjusting screw; two connecting rods fixedly connected to the lifting plate pass through the fixed cylinder and are fixedly connected to the protective frame.

[0010] As an improvement, the operating end of the adjusting screw is located outside the fixed cylinder, and the lifting plate is a cuboid structure corresponding to the inner wall of the fixed cylinder, and the lifting plate is in contact with the inner wall of the fixed cylinder.

[0011] As an improvement, the opening of the protective frame is provided with an elastic sealing gasket.

[0012] The beneficial effects of this utility model are: 1. By incorporating a rotating frame that can swivel around the bottom of the planting rack and an integrated protective frame, the spraying system can be completely stored under the planting rack when not in use, completely avoiding the obstruction of sunlight caused by traditional spray booms fixed above. When spraying is required, the protective frame can be easily rotated to be directly above the planting rack via the rotating frame, and the height of the protective frame can be precisely adjusted via the lifting and adjustment mechanism to ensure the nozzle reaches the optimal spraying height.

[0013] 2. Before the chili peppers emerge or during severe weather such as low temperatures or cold waves, operators can rotate the protective frame and adjust the lifting mechanism to create a temporary heat-insulating cover for the planting rack. This reduces internal heat loss and, combined with the greenhouse environment, creates a more stable and warm microclimate for seed germination, promoting uniform and robust seedling growth.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] This utility model provides a seedling protection frame for greenhouse pepper cultivation: including a support base 1, a support plate 2, and a planting frame 3; two support plates 2 are fixedly mounted on the support base 1, and the planting frame 3 is fixedly connected between the two support plates 2, and a planting trough 4 for planting peppers is opened in the planting frame 3; Reference Appendix Figure 1-3 A rotating frame 6 is rotatably connected to the bottom of the planting frame 3. A protective frame 5 is installed inside the rotating frame 6, which can rotate to the top of the planting frame 3. The protective frame 5, which covers and insulates the planting frame 3, has its opening facing upwards. Several nozzles 11 are installed at the bottom of the protective frame 5 to spray pesticides onto the chili peppers in the planting trough 4. The nozzles 11 are connected to an external pesticide delivery pipe. There are gaps between the protective frame 5, the rotating frame 6, and the planting frame 3 to ensure that the rotating frame 6 and the protective frame 5 do not interfere with or collide with the planting frame 3 and the chili pepper seedlings inside the planting frame 3 during rotation. When the rotating frame 6 is flipped, the protective frame 5 aligns with the planting frame 3. On one hand, the protective frame 5 can be used to cover and insulate the planting frame 3; on the other hand, the nozzles 11 inside the protective frame 5 can be used to spray pesticides onto the chili pepper seedlings. The shape and size of the protective frame 5 correspond to the shape and size of the planting rack 3. An elastic sealing gasket is provided at the opening of the protective frame 5 to increase the covering and sealing effect of the protective frame 5 on the planting rack 3; and ventilation holes are provided on the side wall of the planting rack 3. The planting frame 3 is fixedly connected to two sides by fixed rods 7, which are also fixedly connected to the support plate 2. A rotating plate 8, which is rotatably sleeved on the fixed rods 7, is fixedly connected to the rotating frame 6. The support plate 2 is equipped with a limiting mechanism that can fix the rotating frame 6 before and after rotation. The rotating plate 8 has insertion holes 9. The limiting mechanism consists of two limiting screws 10, which are vertically distributed on the same support plate 2. Both limiting screws 10, which can be inserted into the insertion holes 9 to limit and fix the rotating plate 8 before and after rotation, are threadedly connected to the support plate 2. When the limiting screws 10 are turned, the ends of the limiting screws 10 can be inserted into the insertion holes 9, thereby limiting and fixing the rotating plate 8 before and after rotation, ensuring the stability of the protective frame 5 and the rotating frame 6.

[0022] Reference Appendix Figure 4-5 A fixed cylinder 12 is fixedly installed inside the rotating frame 6. A lifting adjustment mechanism is installed inside the fixed cylinder 12, which can drive the protective frame 5 to slide up and down inside the rotating frame 6. The lifting adjustment mechanism includes an adjusting screw 13, a connecting rod 14, and a lifting plate 15. The adjusting screw 13 is rotatably installed inside the fixed cylinder 12, and the lifting plate 15 located inside the fixed cylinder 12 is threadedly connected to the adjusting screw 13. Two connecting rods 14 fixedly connected to the lifting plate 15 pass through the fixed cylinder 12 and are fixedly connected to the protective frame 5. The operating end of the adjusting screw 13 is located outside the fixed cylinder 12, and the operating end of the adjusting screw 13 is provided with a screw that can fix the operating end of the adjusting screw 13 to the fixed cylinder 12 to ensure the stability of the adjusting screw 13 when it is not in use; the lifting plate 15 is a cuboid structure corresponding to the inner wall of the fixed cylinder 12, and the lifting plate 15 is in contact with the inner wall of the fixed cylinder 12; when the adjusting screw 13 is rotated, the rotation of the adjusting screw 13 can be converted into the sliding of the lifting plate 15, thereby changing the height position of the protective frame 5 by using the connecting rod 14, so as to achieve the effect of adjusting the height of the nozzle 11 or connecting the protective frame 5 with the planting rack 3.

[0023] When pesticides need to be sprayed on chili seedlings, apply the following: Figure 2 , 3 In this state, the operator first loosens the lower limiting screw 10 on the support plate 2 to release the fixing of the rotating frame 6. Then, the operator manually pushes the rotating frame 6 upwards, causing it to rotate around the axis of the fixing rod 7, flipping it from the storage position below the planting rack 3 to directly above the planting rack 3. When the insertion hole 9 on the rotating plate 8 aligns with the hole of another limiting screw 10 above the support plate 2, the operator tightens the limiting screw 10 to securely lock the rotating frame 6 in the working position. Next, refer to the attached... Figure 4 , 5The operator rotates the operating end of the adjusting screw 13, which drives the lifting plate 15 to slide within the fixed cylinder 12 via threaded transmission. This, in turn, changes the position of the protective frame 5 via the connecting rod 14 until the nozzle 11 installed at the bottom of the protective frame 5 reaches the appropriate spraying height. At this point, pesticide solution is supplied to the nozzle 11 through an external pipe, allowing for uniform and comprehensive pesticide spraying of the chili seedlings in the planting trough 4 below. After the operation is completed, the operation is performed in reverse order: first, the protective frame 5 is adjusted to a suitable position to avoid interference or collision with the planting frame 3 and chili peppers during flipping; then, the entire mechanism is flipped back to its original position under the planting frame 3 and locked to prevent shadows from being cast on the planting area.

[0024] When encountering low temperatures and cold waves before the chili seedlings emerge, this device can be switched to heat preservation mode. The first part of its operation is similar to the spraying mode: rotate the rotating frame 6 above the planting rack 3 and lock it. Then, adjust the position of the protective frame 5 by adjusting the screw 13 until the elastic sealing gasket at its opening is tightly fitted to the edge of the planting rack 3, forming a sealed heat preservation cover. This structure effectively reduces heat loss from the seedling growth area, and combined with the macro-environment of the greenhouse, creates a stable and warm local microclimate for seed germination and seedling growth. When the weather improves or sufficient daylight is needed, the entire protective mechanism can be retracted under the planting rack 3 through lifting and flipping operations. This design achieves a clever integration and rapid switching between spraying and heat preservation functions.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
