Technical Field
[0001] The utility model belongs to the technical field of greenhouses, and more specifically, relates to a greenhouse film retracting and extending mechanism. Background Art
[0002] A greenhouse, also known as a hothouse, is a facility used for cultivating plants that allows light to pass through and retains (or heats) heat. During seasons unsuitable for plant growth, it provides a growth period and increases yields. It is often used for cultivating or raising seedlings of warmth-loving vegetables, flowers, and trees during cooler months. There are many types of greenhouses, categorized by roof materials, lighting materials, design, and heating conditions.
[0003] Based on the above, the inventors found that the following problems exist: when planting vegetables in a greenhouse, it is necessary to build a greenhouse with greenhouse covering film, and then plant vegetables in the greenhouse, but the current greenhouse covering film requires multiple people to build when in use, and also requires multiple fixing parts to fix it, which makes the operation more cumbersome.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a greenhouse covering film retracting and extending mechanism is provided, in order to achieve a purpose with greater practical value. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a greenhouse film retracting and extending mechanism to solve the problems in the current background technology.
[0006] The purpose and function of the greenhouse film retracting and unfolding mechanism of the utility model are achieved by the following specific technical means:
[0007] The lifting of the ...
[0008] Furthermore, a pair of hooks are installed on the top of the movable plate, and the inside of the pair of hooks is connected to a retraction rope, and one end of the retraction rope is wound around the outside of the winding roller.
[0009] Furthermore, a clamping groove is provided inside the movable plate, and a pair of through holes are provided on both sides of the movable plate. The internal threads of the through holes are connected to threaded rods, and one end of the threaded rod passes through the movable plate and is installed with a clamping plate.
[0010] Furthermore, a pair of first vertical poles are installed on one side of the interior of the first installation box and the second installation box, and one end of the two pairs of first vertical poles are connected to a connecting block.
[0011] Furthermore, a second vertical pole is hinged on one side of the connecting block, and a connecting block is installed on one end of the second vertical pole. A third vertical pole is hinged inside the connecting block, and a cross bar is connected between several connecting blocks.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The greenhouse film retracting and unfolding mechanism is used in conjunction with rollers, winding rollers, rotating handles, movable plates, slide rails, springs, blocks, retraction ropes, clamping grooves and clamping plates. When the greenhouse film needs to be covered, one end of the film roll is placed in the clamping groove, and then two pairs of threaded rods are rotated respectively to drive the screw rods to move the clamping plates to clamp one end of the film roll. Then, the rotating handle is rotated to drive the winding rollers to rotate, shortening the pair of retraction ropes, pulling the movable plate and the film roll to move on a pair of slide rails, and at the same time, the retraction ropes are pulled. The cam is attached to a plurality of cross bars, and when the retraction rope is shortened, the movable plate is driven to move along the direction of the slide rail. When the movable plate moves to one side of the winding roller, the movable plate is pressed to squeeze a pair of card blocks, so that the spring drives the card blocks to move, and then the movable plate moves downward. The pair of card blocks limits the position of the movable plate, thereby fixing the position of the film, and the operation is fast and convenient. The utility model has a simple and reasonable structure, a novel design, and is simple and convenient to operate. It can effectively build and shrink the film, improve the use efficiency, and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
