Description

Technical Field

[0001] This utility model relates to the field of seedling shed technology, specifically a vegetable seedling shed. Background Technology

[0002] Vegetable seedling greenhouses, as indispensable facilities in modern agricultural production, provide a suitable growing environment for vegetable seedlings. By constructing a relatively enclosed space, vegetable seedling greenhouses can effectively regulate internal environmental factors such as temperature, humidity, and light, providing stable and controllable growth conditions for vegetable seedlings. This improves the survival rate and quality of vegetable seedlings, shortens the seedling cycle, and is of great significance for ensuring a stable supply of vegetables and improving agricultural production efficiency.

[0003] According to a search, Chinese patent document publication number CN208001655U discloses a vegetable seedling shed. It includes a support frame, doors, louvers, a fan, a lifting rod, and a roof. Doors are located at the front and back of the support frame, and louvers are located on both sides. The support frame is covered with transparent plastic, and a fan is mounted on the top beam. The roof is movably mounted on the top of the support frame via the lifting rod. This design allows for temperature control within the vegetable seedling shed.

[0004] However, the aforementioned seedling sheds lack shading structures in actual use. In summer, the excessively high temperature inside the sheds can easily cause vegetable seedlings to suffer from heat scorching, reducing their survival rate and quality. Traditional shading methods mostly use fixed shade nets, which have a fixed shading effect and cannot be flexibly adjusted according to changes in light intensity at different times and under different weather conditions. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a vegetable seedling shed with a shading mechanism and the advantages of easy folding and unfolding of the shading cloth, thus solving the aforementioned technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a vegetable seedling shed, comprising a column, a circular tube, and an arc-shaped plate. A circular tube is welded to the top of the column, and an arc-shaped plate is welded to the outer surface of the circular tube. A horizontal arm is fixedly connected to the side wall of the column. A side plate and a support are fixedly connected to the top surface of the horizontal arm. A shaft is rotatably connected to the inner side of the support. A worm gear and a connecting plate are fixedly connected to the outer surface of the shaft. A sprocket is rotatably connected to the inner side of the support, and a worm gear is rotatably connected to the inner side of the side plate.

[0013] Preferably, the output shaft of the second motor is connected to the worm gear via a coupling, the worm gear is connected to the worm wheel via a transmission, and the clamp is bolted to the outer wall of the round tube.

[0014] Compared with the prior art, this utility model provides a vegetable seedling shed, which has the following beneficial effects:

[0015] 1. This utility model utilizes a No. 1 motor and a No. 2 motor to drive a sprocket and a worm gear mechanism respectively, thereby achieving automatic winding and unwinding of the shade cloth. During winding, the motor drives the winding rod to wind up the shade cloth, while simultaneously bringing the winding rod closer to the fixed rod; to release, simply rotate the motor in the opposite direction. The arc-shaped guide plate and arc-shaped groove are designed to guide the winding rod, and the clamps fix the arc-shaped guide plate to provide support. The entire process is convenient to operate and allows for flexible control of the shade cloth's state according to actual needs, thus improving the practicality of the seedling shed.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5A vegetable seedling shed includes a column 1, a round pipe 2, and an arc-shaped plate 3. The round pipe 2 is welded to the top of the column 1, and the arc-shaped plate 3 is welded to the outer surface of the round pipe 2. A cross arm 4 is fixedly connected to the side wall of the column 1. A side plate 5 and a support 6 are fixedly connected to the top surface of the cross arm 4. A shaft 7 is rotatably connected to the inner side of the support 6. A worm gear 8 and a connecting plate 24 are fixedly connected to the outer surface of the shaft 7. A sprocket 9 is rotatably connected to the inner side of the support 6. A worm gear 10 is rotatably connected to the inner side of the side plate 5. A chain 11 is meshed with the sprocket 9. Chain 11 is meshed with sprocket 12. The center of the end face of sprocket 12 is fixedly connected to a winding rod 13 via a shaft. A sunshade cloth 14 is inserted into the inside of the winding rod 13. A fixing rod 15 is fixedly connected to one end of the sunshade cloth 14. An arc-shaped guide plate 16 is slidably connected to the outer surface of the winding rod 13. A connecting plate 17 is fixedly connected to the outer surface of the arc-shaped guide plate 16. A clamp 18 is fixedly connected to one end of the connecting plate 17. A first motor 19 is installed on one side of the bracket 6. A second motor 20 is installed on the outer surface of the side plate 5.

[0025] Specifically, multiple arc-shaped plates 3 are arranged at equal intervals along the axial direction of the circular tube 2. Several circular tubes 2 are welded to the inner side of the multiple arc-shaped plates 3, and several columns 1 are welded to the outer surface of the circular tubes 2.

[0026] Specifically, side blocks 21 are welded to both ends of the fixing rod 15, and one side of the side block 21 is welded to the side wall of the column 1.

[0027] The advantages are that by setting up a framework of several columns 1, round pipes 2, arc-shaped plates 3, and cross arms 4 to form the seedling shed, a seedling shed is initially formed by covering the outer surface of the framework with a film. By welding the side blocks 21 at both ends of the fixing rod 15 to the side walls of two of the columns 1, which are located at the front and rear ends of the seedling shed respectively, the fixing rod 15 runs through the entire seedling shed. The fixing rod 15 fixes one end of the shade cloth 14, while the other end of the shade cloth 14 is connected to the retracting rod 13. In this way, when the shade cloth 14 is unfolded, it can cover the top of the seedling shed. Since the shade cloth 14 is located in the internal space of the seedling shed, it can avoid the problem of premature aging caused by external placement. In addition, there is a certain gap between the shade cloth 14 and the top film of the seedling shed after it is unfolded, which can prevent the absorption of the temperature of the seedling shed film.

[0028] Specifically, a slot is provided on the outer circumference of the winding rod 13, and a clip 22 is inserted into the slot. The clip 22 cooperates with the slot of the winding rod 13 to hold the sunshade cloth 14.

[0029] Specifically, the output shaft of motor 19 is connected to shaft 7 via a coupling, and an arc-shaped groove 23 is provided through the outer surface of the arc-shaped guide plate 16, with the winding rod 13 slidingly contacting the arc-shaped groove 23.

[0030] The advantage is that when shading is not needed, by starting motor 19 and motor 20, motor 19 drives sprocket 9 to rotate via a coupling. Sprocket 9 then drives sprocket 12 via chain 11. Sprocket 12 drives the winding rod 13 to rotate, which then winds up the shading cloth 14. At the same time, motor 20 drives worm gear 10 to rotate, which in turn drives worm wheel 8. Worm wheel 8 drives shaft 7 to rotate, which in turn drives connecting plate 24 connected to its surface to rotate. Thus, during the winding process, connecting plate 24 causes the winding rod 13 to rotate around the axis of shaft 7, gradually bringing it closer to the fixed rod 15. Similarly, when motors 19 and 20 rotate in opposite directions, the shading cloth 14 can be slowly released, thus providing shading.

[0031] Specifically, the output shaft of motor 20 is connected to worm gear 10 via a coupling, worm gear 10 is connected to worm wheel 8 via a transmission, and clamp 18 is attached to the outer wall of round tube 2 by bolts.

[0032] The advantage is that by setting a clamp 18 to connect to the round tube 2, and the outer wall of the clamp 18 is connected to the connecting plate 17, the arc-shaped guide plate 16 can be fixed, and the arc-shaped guide plate 16 can support the winding rod 13. By opening an arc-shaped groove 23 on the outer surface of the arc-shaped guide plate 16, the movement direction of the winding rod 13 can be guided.

[0033] In use, firstly, the seedling shed frame is composed of several uprights 1, round pipes 2, arc-shaped plates 3, and crossarms 4. A film is then covered on the outer surface of the frame to form the seedling shed. The side blocks 21 at both ends of the fixing rod 15 are welded to the side walls of the uprights 1 at the front and rear ends of the seedling shed to fix one end of the shading cloth 14, and the other end is connected to the retracting rod 13. When shading is not needed, motors 19 and 20 are started. Motor 19 drives the shaft 7 through a coupling, and the sprocket 9 on the shaft 7 drives the sprocket 2 through the chain 11. 12. Rotate the winding rod 13 to wind up the sunshade cloth 14. At the same time, the second motor 20 drives the worm gear 10 through the coupling. The worm gear 10 drives the worm wheel 8. The worm wheel 8 drives the shaft 7. The connecting plate 24 on the shaft 7 drives the winding rod 13 to rotate around the axis of the shaft 7 and move closer to the fixed rod 15. When sunshade is needed, rotate the first motor 19 and the second motor 20 in opposite directions to drive the sunshade cloth 14 to be released slowly, so as to achieve the sunshade effect. During the process, the arc groove 23 on the arc guide plate 16 guides the movement direction of the winding rod 13.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
