DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. EMBODIMENT

[0021] Please refer to Figures 1-7 The present application provides a technical solution: a steel structure agricultural forest breeding greenhouse with seedbed lifting support, comprising a door wall 1, the front of the door wall 1 is provided with an openable and closable door, the back of the door wall 1 is fixedly connected with a steel skeleton 3, the back of the steel skeleton 3 is fixedly connected with a back wall 2, the top of the steel skeleton 3 is fixedly connected with a covering film 4, the top of the covering film 4 is provided with a cleaning mechanism 5, and the inside of the steel skeleton 3 is provided with a defogging mechanism 6. The cleaning mechanism 5 comprises: A closing cover 506 is arranged at the top of the covering film 4. A rotating cylinder 508 is movably connected inside the closing cover 506 through a bearing. A spiral plate 509 is fixedly connected to the outer wall of the drive motor 507.

[0022] The forest seedlings are placed in the seedbed 601 for cultivation. When there is accumulated snow at the top of the covering film 4, the spiral plate 509 is driven by the drive motor 507 to rotate through the rotating cylinder 508. When the spiral plate 509 rotates, it can push the accumulated snow at the top of the covering film 4 to the back of the back wall 2, thereby reducing the amount of accumulated snow at the top of the covering film 4. The traditional snow removal equipment for the top of the covering film 4 causes the accumulated snow to fall on both sides of the covering film 4. With the continuous accumulation of snow on both sides of the covering film 4, the sunlight on both sides of the covering film 4 will be blocked by the snow, thereby reducing the sunlight entering the inside of the covering film 4.

[0023] When there is little snow on the top of the covering film 4, the spiral plate 509 will be difficult to push the little snow on the top of the covering film 4, and the little snow will block part of the sunlight shining into the covering film 4, and after the little snow solution melts, ice is formed on the top of the covering film 4, which increases the reflectivity of sunlight passing through the top of the covering film 4, reducing the light of the seedling in the seedbed 601. The front surface of the rotating cylinder 508 is fixedly connected with the driving motor 507, and the output shaft of the driving motor 507 is fixedly connected with the rotating cylinder 508.

[0024] The rotating cylinder 508 is provided with a plurality of strip-shaped opening structures, and the inner push plate 510 is fixedly connected inside the rotating cylinder 508 at the corresponding opening position.

[0025] When the rotating cylinder 508 is driven by the driving motor 507, and there is little snow on the top of the covering film 4, the spiral plate 509 will not be able to push the snow, at this time, the spiral plate 509 is in a state similar to idling, and the inner push plate 510 is driven to rotate by the rotating cylinder 508. The rotation of the inner push plate 510 causes the air inside the rotating cylinder 508 to be pushed outward by the centrifugal force, and under the limitation of the closing cover 506, an air current is generated to blow to the top of the covering film 4. The air current can blow the little snow on the top of the covering film 4 to the surrounding, further reducing the snowfall on the top of the covering film 4.

[0026] When it snows, snow will accumulate on the entire top of the covering film 4, and the spiral plate 509 needs to rotate back and forth on the top of the covering film 4 to clean the snow on the entire top of the covering film 4. The front surface of the door wall 1 and the back of the back wall 2 are fixedly connected with the guide rail 501, and the top of the guide rail 501 is movably connected with the connecting sliding frame 502. The top of the connecting sliding frame 502 on the front surface of the door wall 1 is fixedly connected with the outer wall of the driving motor 507, and the top of the connecting sliding frame 502 on the back of the back wall 2 is fixedly connected with the back of the closing cover 506. The outer side of the guide rail 501 is fixedly connected with the ring teeth 505, and the outer wall of the connecting sliding frame 502 is fixedly connected with the clutch motor 503. The output shaft of the clutch motor 503 is fixedly connected with the matching teeth 504, and the matching teeth 504 are engaged with the corresponding ring teeth 505. The working principle of the clutch motor 503 inside is as follows: When energized: the motor coil is energized, generating a driving torque to make the rotor rotate; at the same time, the brake coil is also energized; the energized brake coil generates electromagnetic force, overcoming the pressure of the brake spring, releasing the brake disc or brake pad. At this time, the output shaft can be freely rotated by the motor drive; When de-energized: the motor coil is de-energized, losing the driving torque; the brake coil is also de-energized; the electromagnetic force disappears, and the brake spring immediately pushes the brake disc or brake pad to press the brake friction surface connected with the output shaft, generating a strong friction torque; the friction torque will lock the output shaft, making it unable to be rotated by external force; When the brake motor 503 is powered off, the position of the closing cover 506 is locked to avoid the closing cover 506 from shaking freely and causing danger.

[0027] When the two brake motors 503 synchronously drive the corresponding matching teeth 504 to rotate, the matching teeth 504 will push the connecting sliding frame 502 in the opposite direction under the action of meshing with the corresponding ring teeth 505, and through the rotation of the matching teeth 504, the corresponding connecting sliding frame 502 can be moved on the top of the guide rail 501, and through the driving of the brake motor 503, the connecting sliding frame 502 can be moved back and forth on the top of the guide rail 501, so that the closing cover 506 can be moved back and forth on the top of the covering film 4, and the snow on the entire top of the covering film 4 can be cleaned by the spiral plate 509, thereby increasing the light received by the seedlings in the covering film 4. Embodiment

[0028] Please refer to Figures 1-9 Based on the embodiment one, the application provides a technical solution: When it snows outside, some water droplets will be generated on the inner wall of the covering film 4 due to the temperature difference between the inside and outside, which will increase the refraction index of the external light entering the inside of the covering film 4, thereby reducing the effective light intensity reaching the leaves, and the long-term water accumulation will breed green algae and diatoms, forming an algae layer, which will further occupy the sunlight received by the seedlings.

[0029] The defogging mechanism 6 comprises a seedbed 601, the seedbed 601 is arranged in the steel framework 3, and the seedbed 601 is provided with a base 603 at the bottom, the top of the base 603 is fixedly connected with an extension rod 604, and the top of the extension rod 604 is fixedly connected with the bottom of the seedbed 601.

[0030] The extension rod 604 can be extended and retracted to push the seedbed 601 and change the position of the seedbed 601 in the steel framework 3.

[0031] The vibration of the covering film 4 can shake off the water droplets formed on the inner wall of the covering film 4, thereby reducing the water droplets adhered to the inner wall of the covering film 4, the bottom of the seedbed 601 is fixedly connected with a connecting sleeve 602, the inner wall of the connecting sleeve 602 is movably connected with the extension rod 604, and there is a small gap between the inner wall of the connecting sleeve 602 and the outer wall of the extension rod 604, so that the airflow can slowly pass through.

[0032] When the seedbed 601 is pushed up by the telescopic rod 604, the space formed between the connecting sleeve 602 and the base 603 will become larger, and the space between the inside of the covering film 4 and the inside of the connecting sleeve 602 will suddenly become smaller, causing the internal air pressure to increase, which will cause the air inside the covering film 4 to push the covering film 4 outward. Since the covering film 4 has a certain ductility, the covering film 4 will slightly move and bend outward. Then, the telescopic rod 604 pushes the seedbed 601 downward, causing the space between the covering film 4 and the inside of the connecting sleeve 602 to become larger, and the air pressure to decrease. The external air pressure will push the covering film 4 inward. The telescopic rod 604 repeatedly expands and contracts, causing the covering film 4 to move back and forth between the inside and the outside, resulting in a shaking effect of the covering film 4. This can shake off the water droplets attached to the inner wall of the covering film 4, and change the inner wall of the covering film 4 to a water film with a small amount of water.

[0033] At the same time, when the covering film 4 is pushed outward by the internal air pressure, it will also push a small amount of snow on the top of the covering film 4 outward, temporarily reducing the adhesion between the snow and the outer wall of the covering film 4. This facilitates the airflow generated by the rotation of the inner push plate 510 to blow the snow, further reducing the amount of snow falling on the top of the covering film 4.

[0034] The hot air generated inside the covering film 4 will accumulate on the top layer of the covering film 4. The steel skeleton 3 has an exhaust box 605 fixedly connected to the top of the seedbed 601. The exhaust box 605 has exhaust ports 607 on both sides.

[0035] The bottom of the exhaust box 605 is fixedly connected to an air inlet pipe 606, and the air inlet pipe 606 is fixedly connected to a fan motor 608.

[0036] When the fan motor 608 is started, it will push the hot air on the top side of the covering film 4 into the inside of the exhaust box 605 through the air inlet pipe 606, so that the exhaust ports 607 of the exhaust box 605 can exhaust the hot air. The hot air can flow downward along the inner wall of the covering film 4. The shaking of the covering film 4 causes only a water film to exist on the surface of the covering film 4. The airflow will flow to the surface of the water film, thereby being able to dry it, reducing the adhesion of water on the inner wall of the covering film 4, and thereby allowing the seedlings to receive more light.

[0037] At the same time, it can promote the circulation of air inside the covering film 4. The circulation of air inside the covering film 4 can bring multiple benefits: first, it can effectively break the temperature stratification, stir and sink the hot air accumulated at the top of the greenhouse, and make the temperature distribution of the entire greenhouse more uniform, avoiding the stress of crops caused by local high or low temperature; second, the continuous airflow can significantly reduce the humidity on the leaf surface, accelerate water evaporation, and thereby inhibit the growth of diseases such as gray mold and downy mildew. At the same time, the circulating airflow can also ensure the uniform distribution and replenishment of carbon dioxide among the plants. Especially during the period of vigorous photosynthesis, it can avoid the limitation of local carbon dioxide deficiency on growth.

[0038] At the same time, the hot air flow flows in the inner wall of the cover film 4, which can melt the ice on the top of the cover film 4. After the ice melts, the water flow is dispersed by the air flow generated by the inner push plate 510, so that the surface area of the water is increased, and the air flow promotes rapid drying, further increasing the light transmittance of the cover film 4.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change within the technical range disclosed by the present application according to the technical solution and the inventive concept of the present application, which should be covered within the protection scope of the present application.
