Description

Technical Field

[0001] This invention belongs to the field of shading technology for seedling cultivation, specifically relating to a shading structure for seedling cultivation in landscaping. Background Technology

[0002] During the seedling cultivation process, excessive direct sunlight can cause the leaf temperature of seedlings to rise and transpiration to increase, leading to dehydration, wilting, or even scorching and death. At the same time, high temperature and strong light can also inhibit normal photosynthesis. Therefore, using shade nets and other facilities to provide appropriate shading can reduce the temperature and light intensity of the seedbed, reduce water evaporation, and create a suitable microenvironment for seedling growth. This is a key technical measure to ensure the healthy growth of seedlings and improve the seedling survival rate.

[0003] Patent CN214126273U discloses a novel shading device for landscaping seedlings, comprising a lower support column, a fixed frame, a shading device, and a winding mechanism. The fixed frame is located above the lower support column and is rectangular in shape. The lower support column is located at the four corners of the fixed frame. The lower support column includes a sliding rod, a lower support sleeve, and a limiting screw. The winding mechanism is located in a groove and includes a bearing seat, a bearing, a screw, a support bearing, a support frame, a ball bearing, and a motor. The shading device includes a steel ring, a fixing plate, and an elastic shading cloth. This patent belongs to the field of landscaping planting equipment technology. Specifically, it provides a new type of landscaping sapling shading device that facilitates the adjustment of the height and width of the shading device, making it easy to adjust and use for saplings of different heights. It has an internal rolling mechanism for easy rolling and covering of the shading cloth. The device also has an adjustable fixing structure. However, the above device still has the following problems: the shading cloth is prone to wrinkling during the unfolding and use of the device, which affects the subsequent shading effect. Summary of the Invention

[0004] The purpose of this invention is to provide a shading structure for seedling cultivation in landscaping, in order to solve the problem that shading cloth is prone to wrinkling, thereby affecting the subsequent shading effect.

[0005] To achieve the above objectives, the present invention provides a shading structure for seedling cultivation in landscaping, including a heat-insulating shed, the top of which is provided with a shading mechanism, the outer wall of which is provided with an insect-repelling mechanism, and the top of which is provided with a maintenance mechanism. The light-shielding mechanism includes a horizontal support rod, an electric rotating rod, a hollow plate, and a storage compartment. The horizontal support rod is fixedly connected to the outer wall of the heat-insulating shed. The electric rotating rod is rotatably connected to the outer wall of the horizontal support rod. The hollow plate is fixedly connected to the top of the horizontal support rod. The storage compartment is fixedly connected to the top of the heat-insulating shed. The inner wall of the hollow plate is hollowed out and is located on the movement trajectory of the electric rotating rod.

[0006] In the above technical solution, the light-shielding mechanism further includes a winding drum, a light-shielding cloth, a vertical rotating rod, and a limiting wheel. The winding drum is rotatably connected to the inner wall of the storage chamber via a spring. The light-shielding cloth is wound around the outer circumference of the winding drum. The vertical rotating rod is fixedly connected to the bottom of the light-shielding cloth. The limiting wheel is rotatably connected to the outer wall of the vertical rotating rod. The electric rotating rod is rotatably connected to the limiting wheel.

[0007] In the above technical solution, the light-shielding mechanism further includes an inclined rail, a retraction transmission rod, a horizontal pressure plate, and a pressure roller. The inclined rail is fixedly connected to the top of the heat preservation shed, the limiting wheel is slidably connected to the inner wall of the inclined rail, the retraction transmission rod is slidably connected to the inner wall of the storage chamber, the horizontal pressure plate is fixedly connected to the bottom of the retraction transmission rod, the pressure roller is rotatably connected to the bottom of the horizontal pressure plate, the light-shielding cloth is in contact with the pressure roller, and the horizontal pressure plate is connected to the storage chamber by a spring, with the spring sleeved on the outer circumference of the retraction transmission rod. During the compression process, the moisture absorbed by the blackout cloth on the outside is squeezed out by the pressure rollers, preventing the blackout cloth from retaining moisture inside during storage, which could lead to mold growth and reduce the service life of the blackout cloth.

[0008] In the above technical solution, the insect repellent mechanism further includes an inclined block and a vertical guide wire. The inclined block is fixedly connected to the outer wall of the light-blocking cloth, and the vertical guide wire is fixedly connected to the bottom of the inclined block.

[0009] In the above technical solution, the insect repellent mechanism further includes a hollow chamber and a dispersing port. The hollow chamber is fixedly connected to the bottom of the vertical guide wire, the dispersing port is opened on the outer wall of the hollow chamber, and the interior of the hollow chamber is used to store insect repellent powder.

[0010] In the above technical solution, the insect repellent mechanism further includes a dust brush and a dew roller. The dust brush is fixedly connected to the outer wall of the hollow chamber, the dew roller is fixedly connected to the outer wall of the hollow chamber, and the light-blocking cloth is located on the movement trajectory of the dust brush and the light-blocking cloth is located on the movement trajectory of the dew roller. During the contact process between the decondensation roller and the insulation shed, the roller will come into contact with the outer wall of the insulation shed. During this contact, the decondensation roller will squeeze the insulation shed, causing it to become locally concave. This will cause the condensation caused by the temperature difference on the top of the inner wall of the insulation shed to fall off due to the local concavity of the insulation shed, thus preventing a large amount of condensation caused by the temperature difference from adhering to the inner wall of the insulation shed and affecting the overall light transmittance of the insulation shed.

[0011] In the above technical solution, the maintenance mechanism further includes a semi-circular block and a temperature detector. The semi-circular block is slidably connected to the inner wall of the hollow plate, and the temperature detector is fixedly connected to the top of the semi-circular block. The semi-circular block is located on the movement trajectory of the electric rotating rod.

[0012] In the above technical solution, the maintenance mechanism further includes a limiting slider and a limiting groove. The limiting slider is fixedly connected to the outer wall of the temperature detector, and the limiting groove is opened on the outer wall of the hollow plate. The limiting slider and the limiting groove are slidably connected.

[0013] In the above technical solution, the maintenance mechanism further includes a fan-shaped cover, which is fixedly connected to the outer wall of the electric rotating rod and slidably connected to the inner wall of the hollow plate. The inner wall of the hollow plate is located on the movement trajectory of the fan-shaped cover, and the temperature detector is electrically connected to the electric rotating rod. During the unfolding process, the electric rotating rod drives the fan-shaped cover to unfold as well. Once unfolded, the fan-shaped cover will block the front of the insulation shed, increasing the shading area of ​​the device and thus blocking sunlight from the side.

[0014] The beneficial effects of this invention are: 1. In this invention, with the cooperation of the inclined rail, the heat preservation shed, and the winding drum, the shading cloth is unfolded along the inclined rail to block the sunlight projected onto the top of the heat preservation shed and provide shading protection for the seedlings inside. After the shading cloth is fully unfolded, the force of the winding drum's spring-loaded return mechanism still pulls the shading cloth back to its original position. However, the shading cloth is limited and pulled by the electric rotating rod during unfolding. Subsequently, the shading cloth is kept taut under the tension of the electric rotating rod and the winding drum, preventing the shading cloth from wrinkling during unfolding and affecting the shading effect after unfolding.

[0015] 2. In this invention, with the cooperation of the shading cloth, the inclined block, and the hollow chamber, the shading cloth moves downward along with the inclined block and the vertical tie line during its unfolding process. During the downward movement of the inclined block and the vertical tie line, the hollow chamber moves downward as well. When the shading cloth is unfolded, the insect repellent powder inside the hollow chamber will also be suspended on the side of the heat preservation shed. When the shading cloth is unfolded, the insect repellent powder inside the hollow chamber will be dispersed into the surrounding air through the dispersing port, preventing insects from approaching the shading cloth and avoiding insects from staying on the top of the shading cloth to lay eggs, thus preventing the shading cloth from becoming a breeding ground for insects.

[0016] 3. With the cooperation of the insulation shed, temperature detector, and hollow plate, when the external temperature is too high and the insulation shed needs to be shaded, the temperature detector will release an electrical signal to the electric rotating rod. Then the electric rotating rod will start to shade the insulation shed. Subsequently, the semi-circular block will lose the limit of the electric rotating rod, and the temperature detector will also move downward under the limit of the limiting slider. After the temperature detector moves downward, it will be stored on the inner wall of the hollow plate to prevent the temperature detector from being exposed to high temperature for a long time, which would cause the internal temperature sensing device to fail or be damaged, thereby affecting the automation stability of the device.

[0018] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figures 1-7 As shown, one embodiment of the present invention provides: a shading structure for seedling cultivation in landscaping, including a heat-insulating shed 1, a shading mechanism 2 provided on the top of the heat-insulating shed 1, an insect-repelling mechanism 3 provided on the outer wall of the heat-insulating shed 1, and a maintenance mechanism 4 provided on the top of the heat-insulating shed 1. The light-shielding mechanism 2 includes a horizontal support rod 201, an electric rotating rod 202, a hollow plate 203, and a storage compartment 204. The horizontal support rod 201 is fixedly connected to the outer wall of the heat-insulating shed 1. The electric rotating rod 202 is rotatably connected to the outer wall of the horizontal support rod 201. The hollow plate 203 is fixedly connected to the top of the horizontal support rod 201. The storage compartment 204 is fixedly connected to the top of the heat-insulating shed 1. The inner wall of the hollow plate 203 is hollowed out and is located on the movement trajectory of the electric rotating rod 202.

[0020] The light-blocking mechanism 2 also includes a winding drum 205, a light-blocking cloth 206, a vertical rotating rod 207, and a limiting wheel 208. The winding drum 205 is rotatably connected to the inner wall of the storage compartment 204 via a spring. The light-blocking cloth 206 is wound around the outer circumference of the winding drum 205. The vertical rotating rod 207 is fixedly connected to the bottom of the light-blocking cloth 206. The limiting wheel 208 is rotatably connected to the outer wall of the vertical rotating rod 207. The electric rotating rod 202 is rotatably connected to the limiting wheel 208.

[0021] The light-shielding mechanism 2 also includes an inclined rail 209, a retraction transmission rod 210, a horizontal pressure plate 211, and a pressure roller 212. The inclined rail 209 is fixedly connected to the top of the heat preservation shed 1. The limiting wheel 208 is slidably connected to the inner wall of the inclined rail 209. The retraction transmission rod 210 is slidably connected to the inner wall of the storage chamber 204. The horizontal pressure plate 211 is fixedly connected to the bottom of the retraction transmission rod 210. The pressure roller 212 is rotatably connected to the bottom of the horizontal pressure plate 211. The light-shielding cloth 206 is in contact with the pressure roller 212. The horizontal pressure plate 211 and the storage chamber 204 are connected by a spring, and the spring is sleeved on the outer circumferential surface of the retraction transmission rod 210. After the shading cloth 206 is unfolded along the inclined rail 209, it blocks the sunlight projected onto the top of the heat preservation shed 1 to provide shading protection for the seedlings inside. After the shading cloth 206 is fully unfolded, the force of the spring return of the winding drum 205 still pulls the shading cloth 206 to return to its original position. However, the shading cloth 206 is limited and pulled by the electric rotating rod 202 when it is unfolded. Subsequently, the shading cloth 206 will always be in a taut state under the pulling force of the electric rotating rod 202 and the winding drum 205 to prevent the shading cloth 206 from wrinkling when unfolded, which would affect the shading effect after unfolding.

[0022] The insect repellent mechanism 3 also includes an inclined block 301 and a vertical tie line 302. The inclined block 301 is fixedly connected to the outer wall of the light-blocking cloth 206, and the vertical tie line 302 is fixedly connected to the bottom of the inclined block 301.

[0023] The insect repellent mechanism 3 also includes a hollow chamber 303 and a dispersing port 304. The hollow chamber 303 is fixedly connected to the bottom of the vertical tie line 302, and the dispersing port 304 is opened on the outer wall of the hollow chamber 303. The interior of the hollow chamber 303 is used to store insect repellent powder.

[0024] The insect repellent mechanism 3 also includes a dust cleaning brush 305 and a dew removal roller 306. The dust cleaning brush 305 is fixedly connected to the outer wall of the hollow chamber 303, and the dew removal roller 306 is fixedly connected to the outer wall of the hollow chamber 303. The light-blocking cloth 206 is located on the movement trajectory of the dust cleaning brush 305 and the light-blocking cloth 206 is located on the movement trajectory of the dew removal roller 306. As the shading cloth 206 unfolds, it causes the inclined block 301 and the vertical tie line 302 to move downwards. As the inclined block 301 and the vertical tie line 302 move downwards, they also cause the hollow chamber 303 to move downwards. When the shading cloth 206 unfolds, the insect repellent powder inside the hollow chamber 303 will also be suspended on the side of the heat preservation shed 1. When the shading cloth 206 unfolds, the insect repellent powder inside the hollow chamber 303 will be dispersed into the surrounding air through the dispersing port 304, preventing insects from approaching the shading cloth 206 and avoiding insects from staying on the top of the shading cloth 206 to lay eggs, thus preventing the shading cloth 206 from becoming a breeding ground for insects.

[0025] Working principle: When the device is in use, the electric rotating rod 202 drives the limiting wheel 208 to unfold along the guide limit of the inclined rail 209. After the shading cloth 206 is unfolded along the inclined rail 209, it blocks the sunlight projected onto the top of the heat preservation shed 1, providing shading protection for the seedlings inside. After the shading cloth 206 is fully unfolded, the force of the spring return of the winding drum 205 still pulls the shading cloth 206 back to its original position. However, the shading cloth 206 is limited and pulled by the electric rotating rod 202 during unfolding. Subsequently, the shading cloth 206 will always be in a taut state under the tension of the electric rotating rod 202 and the winding drum 205, preventing the shading cloth 206 from wrinkling during unfolding and affecting the shading effect after unfolding. At the same time, the shading cloth 206... During the unfolding process, the vertical rotating rod 207 moves downward, which drives the limiting wheel 208 to move downward. During the unfolding process, the movement trajectory of the limiting wheel 208 is restricted by the inclined rail 209 to prevent the light-blocking cloth 206 from shifting left and right during the unfolding process. When the light-blocking cloth 206 is unfolded, the pressure roller 212 also contacts the light-blocking cloth 206 and can rotate with it, without hindering the normal unfolding of the light-blocking cloth 206. When the light-blocking cloth 206 is rolled up, the pressure roller 212 is squeezed by the horizontal pressure plate 211 and the circumferential spring of the retraction transmission rod 210 to remove the moisture on its surface and prevent the light-blocking cloth 206 from becoming moldy during storage.

[0026] As the blackout cloth 206 unfolds, it causes the inclined block 301 and the vertical tie line 302 to move downwards. This downward movement of the inclined block 301 and the vertical tie line 302 also causes the hollow chamber 303 to move downwards. When the blackout cloth 206 unfolds, the insect repellent powder inside the hollow chamber 303 is also suspended on the side of the heat-insulating shed 1. This powder is then released into the surrounding air through the dispersing port 304, preventing insects from approaching the blackout cloth 206 and avoiding insects from lingering and laying eggs on top of the blackout cloth 206, thus preventing the blackout cloth 206 from becoming an insect breeding ground. The hollow chamber 303 serves as a breeding ground for insects. As the light-blocking cloth 206 is retracted, the hollow chamber 303 moves upwards. After being rolled up, the hollow chamber 303 rises below the storage chamber 204, and the dispensing port 304 is blocked, preventing the insect repellent powder from becoming damp and ineffective. In addition, during the up-and-down movement of the hollow chamber 303, the dust brush 305 cleans the dust adhering to the film on the top of the insulation shed 1. During the movement, the decondensation roller 306 comes into contact with the bottom insulation shed 1, squeezing the insulation shed 1 to make it partially concave, causing the condensation generated on the top of the inner wall of the insulation shed 1 due to the temperature difference to fall off, preventing the condensation from affecting the light transmittance.

[0027] like Figures 1-7 As shown, the second embodiment of the present invention provides: the maintenance mechanism 4 includes a semi-circular block 401 and a temperature detector 402. The semi-circular block 401 is slidably connected to the inner wall of the hollow plate 203, and the temperature detector 402 is fixedly connected to the top of the semi-circular block 401. The semi-circular block 401 is located on the movement trajectory of the electric rotating rod 202.

[0028] The maintenance mechanism 4 also includes a limiting slider 403 and a limiting groove 404. The limiting slider 403 is fixedly connected to the outer wall of the temperature detector 402, and the limiting groove 404 is opened on the outer wall of the hollow plate 203. The limiting slider 403 and the limiting groove 404 are slidably connected.

[0029] The maintenance mechanism 4 also includes a sector cover 405, which is fixedly connected to the outer wall of the electric rotating rod 202 and slidably connected to the inner wall of the hollow plate 203. The inner wall of the hollow plate 203 is located on the movement trajectory of the sector cover 405. The temperature detector 402 and the electric rotating rod 202 are electrically connected. When the external temperature is too high and shading of the insulation shed 1 is required, the temperature detector 402 will release an electrical signal to the electric rotating rod 202. Subsequently, the electric rotating rod 202 will start to shade the insulation shed 1. Then, the semi-circular block 401 will lose the limit of the electric rotating rod 202, and the temperature detector 402 will also move downward under the limit of the limiting slider 403. After the temperature detector 402 moves downward, it will be stored on the inner wall of the hollow plate 203 to prevent the temperature detector 402 from being exposed to high temperature for a long time, which would cause the internal temperature sensing device to fail or be damaged, thereby affecting the automation stability of the device.

[0030] Working principle: During the unfolding process, the electric rotating rod 202 drives the fan-shaped cover 405 to unfold as well. After unfolding, the fan-shaped cover 405 will block the front of the heat preservation shed 1. When the fan-shaped cover 405 is fully unfolded, a certain gap will be left at the bottom for ventilation to prevent heat accumulation inside the heat preservation shed 1 after shading, which would cause the shed to become stuffy and the seedlings to wilt. Leaving a certain gap can increase the shading area of ​​the device while ensuring the ventilation effect inside the heat preservation shed 1. When the shading cloth 206 is retracted, the end of the electric rotating rod 202 will squeeze the semi-circular block 401, which will drive the temperature detector 402 to move upward under the limit of the slider 403. After the temperature detector 402 moves upward, it will detect the external temperature. When the external temperature is too high and shading of the insulation shed 1 is required, the temperature detector 402 will release an electrical signal to the electric rotating rod 202. Subsequently, the electric rotating rod 202 will start to shade the insulation shed 1. Then, the semi-circular block 401 will lose the limit of the electric rotating rod 202, and the temperature detector 402 will also move downward under the limit of the limiting slider 403. After the temperature detector 402 moves downward, it will be stored on the inner wall of the hollow plate 203 to prevent the temperature detector 402 from being exposed to the outside world for a long time and suffering from external environmental pollution and corrosion. Effective recycling can extend its service life.
