Description

Technical Field

[0001] This utility model belongs to the field of greenhouse wall insulation blanket rolling technology, specifically, it relates to a floor-mounted drive mechanism for greenhouse wall insulation blankets. Background Technology

[0002] The closed-type full-light-transmitting greenhouse insulation blanket is a covering material specifically designed for nighttime insulation of greenhouses. Its core feature is that it can be completely rolled up or retracted during the day to ensure that the greenhouse roof can transmit light and maximize the use of solar radiation; while at night it can be fully unfolded and tightly covered to form a closed insulation layer, effectively blocking heat loss, significantly improving the greenhouse insulation performance and reducing energy consumption; when rolling up the insulation blanket, a rolling device is required.

[0003] When the existing greenhouse wall insulation blanket is rolled up, the operator starts the blanket rolling equipment, drives the roller at the ridge to rotate, and the roller pulls the insulation blanket to roll up smoothly along the greenhouse roof, avoiding the insulation blanket from shifting or twisting. The insulation blanket is completely rolled up to the ridge roller, completely separated from the light-transmitting surface, ensuring that the top of the greenhouse is unobstructed to achieve full light transmission.

[0004] However, when the insulation blanket is completely rolled up to the ridge roll, although it can achieve unobstructed light transmission on the front roof, the independent fixing design of the insulation blanket on the greenhouse gable wall will block the gable wall on its fixed side. This will block a small amount of scattered light that the gable wall can receive. This blocked scattered light could have provided some supplementary light to the edge area of ​​the greenhouse. Now that it is missing, the duration and intensity of light in this area are significantly insufficient, which will significantly reduce the light utilization rate of the edge area of ​​the greenhouse. This will not only seriously affect the lighting effect in this area, but also cause uneven heat distribution in the greenhouse due to the deterioration of light conditions. Ultimately, this will have an adverse effect on the crop growth environment and limit the photosynthesis and normal growth and development of crops. Utility Model Content

[0005] In view of the problem that the independent fixed design of greenhouse wall insulation blankets in related technologies blocks a small amount of scattered light that can be obtained by the wall, affecting the lighting effect and crop growth environment in the area, this utility model proposes a ground-mounted drive mechanism for greenhouse wall insulation blankets to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a floor-mounted drive mechanism for insulation blankets on the walls of a solar greenhouse, including a greenhouse body, an insulation blanket rewinding mechanism inside the greenhouse body, an insulation blanket body at the rewinding end of the insulation blanket rewinding mechanism, a plurality of elastic support mechanisms on the surface of the insulation blanket rewinding mechanism, a plurality of elastic adjustment mechanisms inside the plurality of elastic support mechanisms, and an insulation blanket traction mechanism inside the greenhouse body.

[0008] The thermal insulation blanket winding mechanism is used to drive the thermal insulation blanket body to wind up, while the support ends of several elastic support mechanisms provide synchronous support for the wound thermal insulation blanket body.

[0009] Furthermore, the insulation blanket winding mechanism includes a support frame, which is fixedly installed inside the greenhouse body. A motor is fixedly installed at one end of the support frame, and the output shaft of the motor is fixedly connected to a roller. The roller is rotatably connected inside the support frame, and the insulation blanket body is fixedly connected to the surface of the roller.

[0010] Furthermore, the insulation blanket traction mechanism includes a second motor, which is fixedly connected to one side of the greenhouse body. The output shaft of the second motor is fixedly connected to an opening and closing roller, which is rotatably connected inside the greenhouse body. Several steel cables are fixedly installed on the surface of the opening and closing roller, and one end of each steel cable is fixedly connected to one end of the insulation blanket body.

[0011] Furthermore, a reversing wheel is rotatably connected inside the greenhouse body, and several guide wheels are rotatably connected inside the greenhouse body. Several guide grooves adapted to the steel cable are opened on the surface of the reversing wheel and the guide wheels.

[0012] Furthermore, the elastic support mechanism includes a stabilizing frame, which is fixedly connected inside a support frame. A support rod is slidably connected inside the stabilizing frame. A top plate is fixedly connected to one end of the support rod. A limiting plate is fixedly connected to the surface of the support rod. A spring is fixedly connected to one end of the limiting plate. The spring is sleeved on the surface of the support rod. The limiting plate is slidably connected inside the stabilizing frame. Several ball bearings are rotatably connected inside the top plate.

[0013] Furthermore, the elastic adjustment mechanism includes an adjustment plate, the surface of which is fixedly connected to one end of a spring, the adjustment plate being slidably connected inside a stabilizer, a toothed plate being fixedly connected to one end of the adjustment plate, a gear meshing on one side of the toothed plate, and a drive rod being fixedly connected to one end of the gear.

[0014] Furthermore, a motor is fixedly connected to one side of the support frame, a drive wheel is fixedly connected to the output shaft of the motor, a chain is engaged on the surface of the drive wheel, and one end of the drive wheel is fixedly connected to the drive rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses the winding end of the insulation blanket winding mechanism to wind up the insulation blanket body, while the supporting ends of several elastic support mechanisms provide synchronous support for the wound insulation blanket body until the entire insulation blanket body is wound up into the insulation blanket winding mechanism, thus fully exposing the covered area of ​​the greenhouse body. This design changes the drawback of traditional independent fixed gable wall insulation blankets that block the diffused light from the gable wall for a long time, effectively improving the light intensity and duration of the edge area of ​​the greenhouse, making the light distribution inside the greenhouse more uniform, significantly improving the photosynthetic efficiency of crops. The improved light conditions, combined with the reasonable heat conduction in the greenhouse space, greatly alleviate the problem of uneven heat distribution, creating a more suitable growth environment for crops.

[0017] 2. This utility model uses a motor-driven chain linkage system to drive the drive rod and gear to rotate. Through toothed plate transmission, the adjusting plate slides within the stabilizing frame and compresses the spring. This automatically adjusts the pressure applied by the spring to the limiting plate and support rod according to the thickness of the rolled-up insulation blanket. When the thickness of the rolled-up blanket is large, the elastic force is increased to provide stable support, and when the thickness is small, the elastic force is reduced to avoid crushing and breaking. This achieves adaptive dynamic support for rolled-up insulation blankets of different thicknesses.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0033] Please see Figures 1-9As shown, this utility model is a ground-mounted drive mechanism for the insulation blanket of a solar greenhouse wall, including a greenhouse body 1, an insulation blanket winding mechanism 2 is provided inside the greenhouse body 1, an insulation blanket body 3 is provided at the winding end of the insulation blanket winding mechanism 2, a plurality of elastic support mechanisms 4 are provided on the surface of the insulation blanket winding mechanism 2, a plurality of elastic adjustment mechanisms 5 are provided inside the plurality of elastic support mechanisms 4, and an insulation blanket traction mechanism 6 is provided inside the greenhouse body 1.

[0034] The thermal insulation blanket winding mechanism 2 is used to drive the thermal insulation blanket body 3 to wind up, while the support ends of several elastic support mechanisms 4 provide synchronous support for the winding thermal insulation blanket body 3.

[0035] The insulation blanket body 3 is wound up at one end by the winding end of the insulation blanket winding mechanism 2, while the insulation blanket traction mechanism 6 pulls the other end of the insulation blanket body 3 to prevent wrinkles. When the insulation blanket body 3 is being wound up, several elastic support mechanisms 4 provide adaptive support to the sides and bottom of the insulation blanket body 3. At the same time, several elastic adjustment mechanisms 5 can adjust the support force of several elastic support mechanisms 4 according to the thickness of the insulation blanket body 3, so that the several elastic support mechanisms 4 can support the insulation blanket body 3 more stably. Then the insulation blanket body 3 is completely wound up. When it is necessary to open the insulation blanket body 3, the insulation blanket traction mechanism 6 and the insulation blanket winding mechanism 2 are driven in reverse, so that the insulation blanket traction mechanism 6 drives the insulation blanket body 3 to unfold.

[0036] The insulation blanket body 3 is rolled up by the rolling end of the insulation blanket rolling mechanism 2, while the supporting ends of several elastic support mechanisms 4 provide synchronous support for the rolled insulation blanket body 3 until the insulation blanket body 3 is completely rolled up into the insulation blanket rolling mechanism 2, so that the covered area of ​​the greenhouse body 1 is fully exposed. This design changes the drawback of traditional independent fixed gable wall insulation blankets that block the diffused light of the gable wall for a long time, effectively improving the light intensity and duration of the edge area of ​​the greenhouse, making the light distribution inside the greenhouse more uniform, significantly improving the photosynthetic efficiency of crops. The improved light conditions, combined with the reasonable heat conduction in the greenhouse space, greatly alleviate the problem of uneven heat distribution and create a more suitable growth environment for crops.

[0037] In one embodiment, the above-mentioned insulation blanket winding mechanism 2 includes a support frame 201, which is fixedly installed inside the greenhouse body 1. A motor 202 is fixedly installed at one end of the support frame 201. The output shaft of the motor 202 is fixedly connected to a roller 203. The roller 203 is rotatably connected inside the support frame 201, and the surface of the roller 203 is fixedly connected to the insulation blanket body 3.

[0038] The motor 202 drives the roller 203 to rotate, which in turn drives the insulation blanket body 3 to wind around the surface of the roller 203, thereby achieving the winding of the insulation blanket body 3; the support frame 201 supports the roller 203 and the motor 202.

[0039] In one embodiment, the above-mentioned insulation blanket traction mechanism 6 includes a second motor 601, which is fixedly connected to one side of the greenhouse body 1. The output shaft of the second motor 601 is fixedly connected to an opening and closing roller 602, which is rotatably connected inside the greenhouse body 1. Several steel cables 603 are fixedly installed on the surface of the opening and closing roller 602. One end of the steel cables 603 is fixedly connected to one end of the insulation blanket body 3. A reversing wheel 604 is rotatably connected inside the greenhouse body 1, and several guide wheels 605 are rotatably connected inside the greenhouse body 1. Several guide grooves 606 adapted to the steel cables 603 are opened on the surface of both the reversing wheel 604 and the guide wheels 605.

[0040] By sliding the insulation blanket body 3 along the surface of the reversing wheel 604 and several guide wheels 605, several steel cables 603 at one end of the insulation blanket body 3 are wound around the surface of the opening and closing roller 602; when the insulation blanket body 3 is retracted, the reel 203 drives the insulation blanket body 3 to wind around the surface of the reel 203, and at the same time, the motor 601 drives the opening and closing roller 602 to rotate, releasing the steel cables 603 on the surface of the opening and closing roller 602, so that the insulation blanket body 3 slides along the surface of the reversing wheel 604 and several guide wheels 605. As the insulation blanket body 3 slides along the guide groove 606, the steel cable 603 gradually slides along the guide groove 606, limiting the steel cable 603 until the insulation blanket body 3 is completely wrapped by the roller 203. When unfolding, the motor 601 drives the opening and closing roller 602 to rotate in the opposite direction, and at the same time the roller 203 rotates in the opposite direction, so that the opening and closing roller 602 winds the steel cable 603 back, so that the steel cable 603 drives the insulation blanket body 3 to slide along the surface of the reversing wheel 604 and several guide wheels 605, so that the insulation blanket body 3 covers the greenhouse body 1.

[0041] In one embodiment, the elastic support mechanism 4 includes a stabilizer 401, which is fixedly connected inside the support frame 201. A support rod 402 is slidably connected inside the stabilizer 401. A top plate 403 is fixedly connected to one end of the support rod 402. A limiting plate 404 is fixedly connected to the surface of the support rod 402. A spring 405 is fixedly connected to one end of the limiting plate 404. The spring 405 is sleeved on the surface of the support rod 402. The limiting plate 404 is slidably connected inside the stabilizer 401. A plurality of ball bearings 406 are rotatably connected inside the top plate 403.

[0042] When the roller 203 drives the insulation blanket body 3 to wind around the surface of the roller 203, the insulation blanket body 3 is wound around the surface of the roller 203 during the winding process, causing the diameter of the roller 203 to become larger and larger. This causes the surface of the insulation blanket body 3 to come into contact with several ball bearings 406. Guided by the ball bearings 406, the insulation blanket body 3 is not scratched. The ball bearings 406 drive the top plate 403 to move gradually. At the same time, the elastic force of the spring 405 causes the spring 405 to drive the limiting plate 404 to drive the support rod 402 to move. The support rod 402 drives the top plate 403, and the top plate 403 drives the ball bearings 406 to keep in contact with the insulation blanket body 3 on the surface of the roller 203 with the gradually increasing diameter, thus providing adaptive support for the roller 203 and the insulation blanket body 3 during winding.

[0043] In one embodiment, the elastic adjustment mechanism 5 includes an adjustment plate 501, the surface of which is fixedly connected to one end of a spring 405. The adjustment plate 501 is slidably connected inside the stabilizer 401. A toothed plate 502 is fixedly connected to one end of the adjustment plate 501. A gear 503 meshes with one side of the toothed plate 502. A drive rod 504 is fixedly connected to one end of the gear 503. A motor 505 is fixedly connected to one side of the support frame 201. A drive wheel 506 is fixedly connected to the output shaft of the motor 505. A chain 507 meshes with the surface of the drive wheel 506. One end of the drive wheel 506 is fixedly connected to the drive rod 504.

[0044] Motor 505 drives drive wheel 506 to rotate, which in turn drives other drive wheels 506 to rotate synchronously via chain 507. This causes drive wheel 506 to drive drive rod 504 to rotate synchronously. When drive rod 504 rotates, it drives gear 503 to rotate, which in turn moves gear plate 502. The moving gear plate 502 causes adjusting plate 501 to slide inside stabilizer 401. At the same time, adjusting plate 501 compresses one end of spring 405, increasing the elastic force at the other end of spring 405. This causes the other end of spring 405 to drive limit plate 404 to move support rod 402. When in motion, the pressure increases. When winding up insulation blankets 3 of different thicknesses, the weight of the finished product varies. By increasing the elastic force of spring 405, the pressure of spring 405 driving top plate 403 increases. When encountering insulation blankets 3 of high thickness, the elastic force of spring 405 is increased to provide stable support for insulation blankets 3. When encountering insulation blankets 3 of low thickness, the elastic force of spring 405 is reduced to provide stable support for insulation blankets 3, so as to prevent excessive elastic force from causing insulation blankets 3 to be squeezed and broken. It can adapt to the winding of insulation blankets 3 of different thicknesses and realize the dynamic support of insulation blankets 3.

[0045] Through the above technical solution, 1. The first motor 202 drives the roller 203 to rotate, causing the roller 203 to drive the insulation blanket body 3 to wind around the surface of the roller 203, thereby achieving the winding of the insulation blanket body 3. At the same time, the second motor 601 drives the opening and closing roller 602 to rotate, releasing the steel cable 603 on the surface of the opening and closing roller 602, allowing the insulation blanket body 3 to slide along the reversing wheel 604 and several guide wheels 605. Simultaneously, the steel cable 603 gradually slides along the guide groove 606. During the winding process, the insulation blanket body 3 is wound around the surface of the roller 203, causing the diameter of the roller 203 to become larger and larger, so that the surface of the insulation blanket body 3 contacts several ball bearings 406. Guided by several ball bearings 406, the insulation blanket body 3 is not scratched. The ball bearings 406 drive the top plate 403 to move gradually. At the same time, the elastic force of the spring 405 drives the limiting plate 404 to drive the support rod 402 to move. The support rod 402 drives the top plate 403, and the top plate 403 drives the ball bearings 406 to contact the insulation blanket body 3 on the surface of the gradually increasing diameter roller 203. The roller 203 and the insulation blanket body 3 during winding provide adaptive support until the insulation blanket body 3 is completely wrapped by the roller 203, completing the winding of the insulation blanket body 3 and allowing the greenhouse body 1 to be fully unfolded.

[0046] 2. The motor drives the chain 507 linkage system to drive the drive rod 504 and gear 503 to rotate. The toothed plate 502 drives the adjusting plate 501 to slide within the stabilizer 401 and compress the spring 405. Thus, the pressure applied by the spring 405 to the limiting plate 404 and support rod 402 is automatically adjusted according to the thickness of the rolled-up insulation blanket. When the thickness of the rolled-up blanket is large, the elastic force is increased to provide stable support. When the thickness is small, the elastic force is reduced to avoid crushing and breaking. This achieves adaptive dynamic support for the rolled-up insulation blankets of different thicknesses.
