Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses, in particular to a sunshade mechanism for greenhouses. Background Art

[0002] Greenhouses, also known as hot houses, are facilities used to grow plants. They are light-transmitting and heat-insulating. In seasons that are not suitable for plant growth, they can provide a greenhouse growth period and increase production. They are mostly used for the cultivation or seedling raising of warm-loving vegetables, flowers, trees and other plants in low-temperature seasons.

[0003] Existing greenhouses are seriously affected by the direct sunlight at noon, which is not conducive to their normal growth. The conventional shading method is to lay a shade cloth on the top. In order to realize the automated rolling and laying process, a pair of winding shafts are usually installed on the top of the greenhouse to release the shade cloth to both sides to cover the greenhouse. However, in this method, since the lower edge of the lowered shade cloth is not fixed, it is easy to be lifted or swung when there is wind outdoors, affecting the shading effect. The swinging process is also easy to rub the greenhouse film and cause damage. Summary of the invention

[0004] In view of the above problems, the utility model provides a sunshade mechanism for a greenhouse. The sunshade mechanism uses multiple pull ropes to pull the sunshade cloth across the greenhouse. Both ends of the sunshade cloth are in a locked state and will not be affected by the wind. In the unshaded state, the top of the greenhouse is not blocked and the light transmission effect is not affected.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is:

[0006] A sunshade mechanism for a greenhouse comprises a greenhouse, wherein a left box body and a right box body extending along the length direction of the greenhouse are respectively fixed on both sides of the bottom of the greenhouse, and the left box body and the right box body are rotatably connected with a winding shaft extending along the length direction of the greenhouse, a sunshade cloth is wound on the winding shaft in the left box body, and a plurality of pull ropes are wound on the winding shaft in the right box body at equal intervals, and a plurality of guide frames spanning the greenhouse are fixedly installed between the left box body and the right box body, and the ends of the plurality of pull ropes are connected to the sunshade cloth through the corresponding guide frames.

[0007] Preferably, the top of the left box body is provided with a strip opening for the sunshade cloth to pass through, and the top of the right box body is provided with a plurality of wire holes for the corresponding pull ropes to pass through.

[0008] Preferably, the shape of the guide frame is adapted to the shape of the greenhouse, and the positions of the multiple guide frames and the multiple pull ropes correspond one to one.

[0009] Preferably, the side wall of the guide frame is provided with a wire groove extending along the guiding direction thereof, and the pull rope is located in the wire groove.

[0010] Preferably, a slider is fixedly connected between the end of the sunshade cloth and the end of the pull rope, and the slider is slidably installed in the wire groove.

[0011] Preferably, a driving box is fixedly installed on the front bottom of the greenhouse, the front ends of the two winding shafts extend to the corresponding ends of the driving box and are fixed with worm gears, a transversely arranged driving shaft is rotatably connected in the driving box, both ends of the driving shaft are serially connected with worms meshing with corresponding worm gears, and a motor that can drive the driving shaft to rotate is installed at one end of the driving box.

[0012] The beneficial effects of the utility model are:

[0013] 1. By installing two reel shafts, multiple stretch ropes and sunshade cloths, when shading is needed, you only need to start the motor, and drive the two reel shafts to rotate in the same direction through the drive shaft, worm and worm gear. While reeling in the pull rope, the sunshade cloth is in the unwinding state, and then the sunshade cloth can be pulled out to cover the greenhouse. It is convenient to use, and both ends of the sunshade cloth are in a pulling state, and will not be lifted or swing violently due to the influence of wind.
