Description

Technical Field

[0001] This utility model relates to the field of stepped seedling rack technology, and in particular to an adjustable ventilation device for a stepped seedling rack. Background Technology

[0002] A tiered seedling rack is a seedling facility with a unique tiered structure. By arranging multiple seedling platforms in a tiered manner, it makes full use of vertical space for seedling cultivation, creating favorable environmental conditions for seedling growth. During seedling cultivation, the ventilation of the tiered seedling rack needs to be adjusted to ensure the quality of seedling growth.

[0003] According to the search, the Chinese patent "An Automatic Sprinkler Device for Seedlings" (authorization announcement number "CN220654207U") uses multiple water spray pipes to spray water on seedlings on different steps of the seedling platform. By turning on the fan, the air flow near the steps of the seedling platform can be accelerated to achieve ventilation, which helps the seedlings grow.

[0004] While the forced ventilation using fans mentioned above can regulate the airflow on the seedling platform steps to some extent, it relies on an electric power supply for ventilation, and the water spray pipes are prone to splashing water into the fans, causing damage. This increases operating costs and maintenance difficulty, thus affecting the seedling effect. Utility Model Content

[0005] Therefore, it is necessary to provide an adjustable ventilation device for a stepped seedling rack to address the problem that ventilation relies on power supply and that water spraying from the water pipes can easily cause splashing into the fan and damage, thereby increasing operating costs and maintenance difficulty.

[0006] The device includes: a tiered seedling rack; and a control device comprising several transparent frames fixedly connected to the top of the tiered seedling rack. A ventilation window is hinged to one side of each transparent frame. Two movable blocks are hinged to the inner wall of each ventilation window. A slide is hinged to the lower surface of each movable block. A rack is fixedly connected to the end of each slide. A gear is meshed to one side of the rack. A lever is fixedly connected to the inner wall of the gear. The surface of the lever is rotatably connected to the inner wall of the tiered seedling rack.

[0007] In one embodiment, the inner wall of the stepped seedling rack is slidably connected with a positioning rod and a positioning block, the surface of the positioning rod is engaged with the inner wall of the actuating rod, and the surface of the positioning block is slidably connected to the inner wall of the positioning rod.

[0008] In one embodiment, a spring is fixedly connected to one end of the positioning rod, and the other end of the spring is fixedly connected to the rear end of the stepped seedling rack.

[0009] In one embodiment, a rubber ring is fixedly connected to the top of the transparent frame, and the inner wall of the ventilation window is snapped onto the surface of the rubber ring. The rubber ring is used to seal the connection between the transparent frame and the ventilation window, preventing air leakage at the connection point and thus ensuring the seedling cultivation effect of the tiered seedling rack.

[0010] In one embodiment, a protective frame is fixedly connected to the bottom of the stepped seedling rack, and the surface of the actuating rod is rotatably connected to the inner wall of the protective frame.

[0011] In one embodiment, a stop block and a weight rod are slidably connected to the upper end of the inner wall of the guard frame. The surface of the weight rod is engaged with the inner wall of the stop block, and the surface of the stop block is U-shaped. By moving the weight rod away from the inside of the stop block and the stop block away from the inside of the guard frame, the front and rear ends of the guard frame are open, which facilitates the lubrication of the gears and racks, thereby reducing the difficulty of subsequent maintenance of the gears and racks.

[0012] In one embodiment, a plurality of rubber corrugated pads are fixedly connected to the end of the carriage, and the other end of the rubber corrugated pads is fixedly connected to the inner wall of the protective frame. Through the cooperation of the protective frame and the rubber corrugated pads, the gears and racks are protected, reducing the adhesion of impurities to their surfaces, thereby reducing wear and tear and simplifying subsequent maintenance.

[0013] In one embodiment, the surface of the carriage is slidably connected to the inner wall of the guard frame, and the surfaces of the rack and gear are both located inside the guard frame.

[0014] Beneficial effects 1. By cooperating with levers, gears, racks, slides and movable blocks, the opening and closing angles of multiple ventilation windows can be adjusted synchronously, ensuring uniform ventilation within multiple transparent frames, avoiding localized hypoxia or overheating of seedlings, thus avoiding reliance on electric power for ventilation, reducing operating costs and maintenance difficulty. The adaptive control of ventilation volume inside the transparent frame is easy to operate, requires no external power, and is suitable for greenhouse or shed seedling cultivation. 2. The spring's elastic force pushes the positioning rod to move laterally within the stepped seedling rack and locks it inside the actuating rod. The positioning block slides into the positioning rod, thereby locking the actuating rod and preventing the ventilation window from shifting after angle adjustment. This ensures uniform ventilation inside the transparent frame and thus guarantees the seedling effect of the stepped seedling rack. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-5 This invention describes an adjustable ventilation device for a stepped seedling rack.

[0020] In one embodiment, an adjustable ventilation device for a stepped seedling rack includes: a stepped seedling rack 100; and a control device 200. The control device 200 includes several transparent frames 201 fixedly connected to the top of the stepped seedling rack 100. A ventilation window 202 is hinged to one side of each transparent frame 201. Two movable blocks 203 are hinged to the inner wall of the ventilation window 202. A slide 204 is hinged to the lower end of the surface of each movable block 203. A rack 205 is fixedly connected to the end of the slide 204. A gear 206 is meshed to one side of the rack 205. A lever 207 is fixedly connected to the inner wall of the gear 206. The surface of the lever 207 is rotatably connected to the inner wall of the stepped seedling rack 100.

[0021] It should be noted that a spray pipe is installed on one side of the inner wall of the transparent frame 201. One end of the spray pipe penetrates and extends out of the inner wall of the transparent frame 201. One end of the spray pipe can be connected to the water supply pipe by thread, thereby supplying water to the spray pipe and allowing the spray pipe to spray water on the seedlings inside the transparent frame 201. The specific water supply method to the spray pipe can be selected according to actual needs, which will not be elaborated here. The seedling tray containing the seedlings is placed on top of the stepped seedling rack 100 through the top opening of the transparent frame 201.

[0022] In this embodiment, the stepped seedling rack 100 is placed in a place with sufficient light, such as a greenhouse or shed, so that light shines on the seedlings in the seedling tray through the transparent frame 201 and the ventilation window 202. In the initial state, the bottom of the transparent frame 201 touches the top of the ventilation window 202, thereby sealing the top opening of the ventilation window 202, and controlling the temperature of the seedling environment according to the growth habits of the crop.

[0023] When the ventilation on the stepped seedling rack 100 needs to be adjusted, rotate the lever 207. The rotation of the lever 207 drives the gear 206 to rotate. The rotating gear 206 pushes the rack 205 to move upward. The upward-moving rack 205 drives the slide 204 to move upward. The upward-moving slide 204 pushes the movable block 203 and the ventilation window 202 to adjust their angles, thereby allowing multiple ventilation windows 202 to adjust to appropriate opening and closing angles simultaneously. At this time, outside air enters the vicinity of the seedling tray through the opening of the open transparent frame 201, thereby providing uniform ventilation to the seedlings inside each transparent frame 201 at the top of the stepped seedling rack 100.

[0024] The growth of seedlings inside the transparent frame 201 needs to be checked regularly to detect and prevent diseases and pests in a timely manner. When the seedlings grow to a certain size, they can be transplanted inside the transparent frame 201.

[0025] like Figure 3As shown, a positioning rod 208 and a positioning block 209 are slidably connected to the inner wall of the stepped seedling rack 100. The surface of the positioning rod 208 is engaged with the inner wall of the actuating rod 207, and the surface of the positioning block 209 is slidably connected to the inner wall of the positioning rod 208. A spring 210 is fixedly connected to the end of the positioning rod 208, and the other end of the spring 210 is fixedly connected to the rear end of the stepped seedling rack 100.

[0026] In this embodiment, after the ventilation window 202 is opened and closed to a suitable angle, the rotation of the lever 207 is stopped, the restriction on the positioning lever 208 is loosened, the elastic force of the spring 210 pushes the positioning lever 208 to move laterally within the stepped seedling rack 100 and lock it within the lever 207, and pushes the positioning block 209 to move laterally within the stepped seedling rack 100 and lock it within the positioning lever 208, thereby locking the lever 207.

[0027] like Figure 2 As shown, a rubber ring 214 is fixedly connected to the top of the transparent frame 201, and the inner wall of the ventilation window 202 is snapped onto the surface of the rubber ring 214.

[0028] like Figure 4-5 As shown, a protective frame 211 is fixedly connected to the bottom of the stepped seedling rack 100. The surface of the actuating rod 207 is rotatably connected to the inner wall of the protective frame 211. A stop block 212 and a weight rod 213 are slidably connected to the upper end of the inner wall of the protective frame 211. The surface of the weight rod 213 is engaged with the inner wall of the stop block 212, and the surface of the stop block 212 is U-shaped. Several rubber corrugated pads 215 are fixedly connected to the end of the slide 204. The other end of the rubber corrugated pads 215 is fixedly connected to the inner wall of the protective frame 211. The surface of the slide 204 is slidably connected to the inner wall of the protective frame 211. The surfaces of the rack 205 and the gear 206 are both located inside the protective frame 211. The weight rod 213 is a cast iron component, giving it a certain weight.

[0029] In this embodiment, when the rack 205 and gear 206 need to be lubricated and maintained, the weight rod 213 is pulled up and away from the stop block 212, and the stop block 212 is pulled to move laterally within the guard frame 211, so that the upper surface of the guard frame 211 is opened. At this time, lubricating oil is applied to the surface of the gear 206 and rack 205 for lubrication and maintenance. After lubrication is completed, the stop block 212 is pushed to seal the upper surface of the guard frame 211, loosening the restriction on the weight rod 213. The weight rod 213 moves down and gets stuck in the stop block 212 due to its own weight.

[0030] Working principle: Pull the positioning block 209 away from the positioning rod 208, pull the positioning rod 208 away from the actuating rod 207, rotate the actuating rod 207, the rotation of the actuating rod 207 drives the slide 204 to move upward through the gear 206 and rack 205, the upward slide 204 pushes the movable block 203 and ventilation window 202 to adjust the angle, thereby making multiple ventilation windows 202 adjust to the appropriate opening and closing angle at the same time, loosening the restriction on the positioning rod 208, the elastic force of the spring 210 pushes the positioning rod 208 to be locked in the actuating rod 207, pushes the positioning block 209 to be locked in the positioning rod 208, thereby locking the actuating rod 207. At this time, outside air enters the vicinity of the seedling tray through the opening of the open transparent frame 201, thereby providing uniform ventilation for the seedlings inside each transparent frame 201 at the top of the stepped seedling rack 100.

[0031] It should be noted that the stepped seedling rack 100, transparent frame 201, ventilation window 202, rack 205, gear 206, spring 210 and weight bar 213 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
