Description

Technical Field

[0001] This utility model relates to the field of greenhouse shading technology, and in particular to an external shading structure for greenhouses. Background Technology

[0002] Greenhouse shading systems refer to devices installed in greenhouses to regulate light and temperature. They are mainly divided into two categories: external shading and internal shading. The main function of greenhouse shading systems is to block solar radiation and regulate light and temperature inside the greenhouse. External shading systems are usually installed on the top covering material of the greenhouse and are mainly used for summer shading and cooling to prevent strong sunlight from scorching crops and to lower the temperature inside the greenhouse.

[0003] However, the current method of covering the greenhouses is done manually. Because the greenhouses are quite tall, the shade cloth needs to be covered manually, which is dangerous and inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an external shading structure for greenhouses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A greenhouse external shading structure includes a mounting frame and a resetting mechanism. A shading mechanism is fixed to the inner side of the mounting frame. The shading mechanism can be unfolded to facilitate shading inside the greenhouse. A pull rope is connected to the top of the shading mechanism. A first guide wheel and a guide mechanism are respectively installed on the surface of the mounting frame. A winding mechanism is fixedly connected to the lower sides of the mounting frame.

[0007] Preferably, the sunshade mechanism includes a sunshade cloth, the inner side of the mounting frame is fixedly connected to one end of the sunshade cloth, and the other end of the sunshade cloth is fixedly connected to the side of the movable rod, and the upper part of the movable rod is fixedly connected to...

[0008] Preferably, the guiding mechanism includes mounting side plates, the mounting side plates are fixedly connected to both ends of the mounting frame, and a second guide wheel is mounted inside the mounting side plate via a bearing. A first guide wheel is mounted on the upper end of the mounting frame via a bearing. The surfaces of the first guide wheel and the second guide wheel are both in contact with the pulling rope.

[0009] Preferably, the winding mechanism includes a winding frame, the lower surface of the mounting frame is fixedly connected to the winding frame, and a drive motor is installed at the outer end of the winding frame. The output end of the drive motor is fixedly connected to the winding shaft, and a connector is fixedly attached to the surface of the winding shaft.

[0010] Preferably, the surface of the take-up shaft is fitted with multiple sets of blocking discs at equal intervals, and each set of blocking discs has two symmetrically arranged discs. The upper surface of the take-up frame is provided with multiple sets of through holes at equal intervals.

[0011] Preferably, the reset mechanism includes a connecting block, and a driving crossbar is fixedly connected to the lower part of the moving rod through the connecting block. A guide post is inserted inside the driving crossbar, and a mounting frame is fixedly connected to both ends of the guide post.

[0012] Preferably, the driving crossbar is configured as an annular shape, and a limiting slider is fixedly connected to the inner wall of the driving crossbar. The guide post has a groove inside that matches the limiting slider, and a return spring is welded between the inner wall of the groove and the limiting slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The device uses the elastic force of the return spring to easily push the limit slider to move along the guide column, thereby allowing the drive bar to slide along the surface of the guide column, which facilitates the unfolding of the shading cloth by the moving rod. This allows the shading cloth to provide shade for the greenhouse. At the same time, by matching the inner wall size of the drive bar with the surface size of the guide column, it can guide the moving rod while reducing its own wear.

[0015] The device can drive the winding shaft to rotate within the winding frame via a drive motor, facilitating the winding of the connector. Guided by the first and second guide wheels, the pull rope can be pulled to the moving rod for movement, allowing the sunshade cloth to be stored when not in use. At the same time, multiple sets of blocking discs fitted onto the surface of the winding shaft can limit and guide the winding of the connector. Attached Figure Description

The moving rod 22 is fixedly connected to the top of the moving rod 22, and the pulling rope 3 can be easily connected and fixed through the 23.

[0024] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the guiding mechanism 5 includes a mounting side plate 51. The mounting side plates 51 are fixedly connected to both ends of the mounting frame 1. The mounting side plates 51 are installed with a second guide wheel 52 through a bearing. The second guide wheel 52 is mounted with a bearing, which can facilitate its cooperation with the first guide wheel 4 to guide and change the direction of the pull rope 3. The upper end of the mounting frame 1 is installed with a first guide wheel 4 through a bearing. The surfaces of the first guide wheel 4 and the second guide wheel 52 are both in contact with the pull rope 3.

[0025] Furthermore, refer to Figure 1 and Figure 3 and Figure 4It can be seen that the winding mechanism 6 includes a winding frame 61. The winding frame 61 is fixedly connected to the lower surface of the mounting frame 1, and a drive motor 62 is installed at the outer end of the winding frame 61. The drive motor 62 can drive the winding shaft 63 to rotate inside the winding frame 61. The output end of the drive motor 62 is fixedly connected to the winding shaft 63, and a connector 64 is fixedly fixed on the surface of the winding shaft 63. The connector 64 can be wound up when the winding shaft 63 rotates through the connector 64 fixed on the surface of the winding shaft 63.

[0026] Furthermore, refer to Figure 4 It can be seen that multiple sets of blocking discs 65 are equidistantly sleeved on the surface of the winding shaft 63, and two blocking discs 65 are symmetrically arranged in each set. The two blocking discs 65 in each set can play the role of limiting and venting. Multiple sets of through holes are equidistantly opened on the upper surface of the winding frame 61. The rope 3 and the connector 64 can be easily moved and wound up through the equidistant through holes opened on the upper surface of the winding frame 61.

[0027] Furthermore, refer to Figure 1 and Figure 3 It can be seen that the reset mechanism 7 includes a connecting block 71.
