Description

Technical Field

[0001] The present invention belongs to the technical field of greenhouse cultivation, and particularly relates to a greenhouse film fixing device. Background Art

[0002] As a product of the development of modern agriculture, greenhouses have been widely popularized. Especially in alpine regions, sandy deserts and arid regions, they play a significant role in resisting low temperature, drought and sandstorm hazards. The tops of existing greenhouses are all covered with plastic films, and it is necessary to ensure the light transmittance of the plastic films to ensure sufficient sunlight for the plants in the greenhouses;

[0003] It is found in the actual use process that in the prior art, for the covering and fixing of films, stones and other heavy objects are still mostly used to press the edges to achieve the purpose. While the efficiency is low, the wind resistance effect is not good and it is easy to be blown away. Summary of the Invention

[0004] Aiming at the problems raised in the above background art, the purpose of the present invention is to provide a greenhouse film fixing device.

[0005] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0006] A greenhouse film fixing device includes sewage discharge grooves on four sides of the planting area. A first motor and a second motor are installed in the sewage discharge grooves. The output end of the first motor is connected to a first rotating shaft, and the output end of the second motor is connected to a second rotating shaft. A plurality of rope buckles are evenly arranged on both the first rotating shaft and the second rotating shaft. Support mechanisms are adaptively installed on both the first rotating shaft and the second rotating shaft. The support mechanism includes a support seat. The installation surface of the support seat contacts the bottom of the sewage discharge groove, and the support seat is not in contact with both the first rotating shaft and the second rotating shaft. A support column is connected to the top of the support seat. The support column is connected to a slide rail. A slide bar is slidably connected to the slide rail. The slide rail is provided with fixing holes, and the slide bar is provided with fixing screws adapted to the fixing holes. An installation block is fixedly installed on the slide bar. A pressing strip is fixedly installed on the installation block of one of the support mechanisms, and an inner strip is fixedly installed on the installation block of the other support mechanism. The other ends of both the pressing strip and the inner strip are connected with wire ropes. The wire ropes pass through the installation block, the slide rail, the support column and the support seat and are fixed on the first rotating shaft or the second rotating shaft through the rope buckles.

[0007] Further defined, both the first motor and the second motor are waterproof motors. Such a design ensures the use effect.

[0008] Further defined, both the first rotating shaft and the second rotating shaft are adaptively installed with support platforms through bearings. Such a design ensures the rotation effect of the first rotating shaft and the second rotating shaft.

[0009] Further defined, the two sides of the pressing strip are connected with edge guards, and the inner strip is located between the two side edge guards. With such a design, the pressing and covering effect is better.

[0010] Further defined, both the pressing strip and the inner strip are elastic metal strips. With such a design, they are corrosion-resistant and durable.

[0011] Further defined, the support is U-shaped, and the two sides of the support are connected with ear plates, and the ear plates are provided with threaded holes. With such a design, the fixed support effect of the support is strengthened.

[0012] Further defined, the slide rail and the support column are detachably connected. With such a design, it is convenient for maintenance and replacement.

[0013] Further defined, pulleys are installed at the corner connection parts of the slide rail and the mounting block with the wire rope. With such a design, while ensuring the sliding effect of the wire rope, the wear of the wire rope is reduced.

[0014] Further defined, magnets are evenly installed on the pressing strip. With such a design, the compaction effect between the pressing strip and the inner strip is strengthened.

[0015] Advantages of adopting the present invention:

[0016] The present invention makes the first rotating shaft and the second rotating shaft rotate by controlling the rotation of the first motor and the second motor, thereby driving the wire rope to wind around the first rotating shaft or the second rotating shaft. The wire rope wound around the second rotating shaft will pull the inner strip to bend, and the wire rope wound around the first rotating shaft will pull the pressing strip to bend. Therefore, as long as the film is laid on the inner strip after the inner strip bends, and then the pressing strip is pressed on the inner strip, the fixation of the film can be achieved. Therefore, the work of relevant personnel is only to lay the film and press both sides of the film, which is convenient, fast, automatically fixed, and has high efficiency;

[0017] The present invention can adjust the length of the sliding strip, so as to adapt to different widths of planting areas, and has a wide range of uses; BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manners

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to the drawings and embodiments.

[0026] As Figures 1 to 4 shown, a fixing device for greenhouse film of the present invention includes a sewage discharge groove 1 provided on four sides of the planting area. A first motor 3 and a second motor 4 are installed in the sewage discharge groove 1. The output end of the first motor 3 is connected to a first rotating shaft 5, and the output end of the second motor 4 is connected to a second rotating shaft 6. A plurality of rope buckles 7 are evenly provided on both the first rotating shaft 5 and the second rotating shaft 6. Support mechanisms 8 are adaptively installed on both the first rotating shaft 5 and the second rotating shaft 6. The support mechanism 8 includes a support 81. The mounting surface of the support 81 contacts the bottom of the sewage discharge groove 1, and the support 81 does not contact the first rotating shaft 5 and the second rotating shaft 6. A support column 82 is connected to the top of the support 81. A slide rail 83 is connected to the support column 82. A sliding strip 84 is slidably connected to the slide rail 83. The slide rail 83 is provided with a fixing hole 85. The sliding strip 84 is provided with a fixing screw 86 adapted to the fixing hole 85. A mounting block 87 is fixedly installed on the sliding strip 84. A pressing strip 9 is fixedly installed on the mounting block 87 of one of the support mechanisms 8, and an inner strip 10 is fixedly installed on the mounting block 87 of the other support mechanism 8. The other ends of the pressing strip 9 and the inner strip 10 are both connected to a wire rope 11. The wire rope 11 passes through the mounting block 87, the slide rail 83, the support column 82 and the support 81 and is fixed to the first rotating shaft 5 or the second rotating shaft 6 through the rope buckle 7.

[0027] In this embodiment, when using a greenhouse film fixing device, first determine the area of the planting area, then determine the number of support mechanisms 8 and the corresponding pressing strips 9 and inner strips 10 to be used according to the area of the planting area, and install the support mechanism 8 at the corresponding positions on the first rotating shaft 5 and the second rotating shaft 6. Fix the wire rope 11 passing through the support 81 on the first rotating shaft 5 through the rope buckle 7. Then, the relative distance between the two side sliders 84 can be controlled according to the area of the planting area, that is, the covering width of the pressing strip 9 and the inner strip 10 can be controlled. The adjustment method is to pull the slider 84 in the slide rail 83, and then use the fixing screw 86 to cooperate with the fixing hole 85 to fix the position of the slider 84. After the position is determined, first control the second motor 4 to drive the second rotating shaft 6 to rotate, so that the second rotating shaft 6 winds the wire rope 11. Therefore, under the effect of the wire rope 11, the inner strip 10 will be pulled to bend, so that all the installed inner strips 10 are arched and located on the planting area. Then, manually place the film directly on the inner strip 10, control the first motor 3 to drive the first rotating shaft 5 to rotate, so that the first rotating shaft 5 winds the wire rope 11, pull the pressing strip 9 to bend, and make the installed pressing strip 9 arch and press on the inner strip 10, that is, the pressing and fixing of the film is completed. Then, manually compact both ends of the film, which is convenient and fast. Moreover, with the cooperation of the pressing strip 9 and the inner strip 10, the wind resistance effect of the film between adjacent two pressing strips 9 is good.

[0031] Preferably, both the pressing strip 9 and the inner strip 10 are elastic metal strips. Such a design is corrosion-resistant and durable. In fact, the material selection of the pressing strip 9 and the inner strip 10 can also be considered according to specific circumstances.

[0032] Preferably, the support 81 is U-shaped, and both sides of the support 81 are connected with ear plates 811, and the ear plates 811 are provided with threaded holes. Such a design strengthens the fixed support effect of the support 81. In fact, the structure and fixing method of the support 81 can also be considered according to specific circumstances.

[0033] Preferably, the slide rail 83 is detachably connected to the support column 82. Such a design facilitates maintenance and replacement. In fact, the connection method between the slide rail 83 and the support column 82 can also be considered according to specific circumstances.

[0034] Preferably, pulleys are installed at the corner joints of the slide rail 83 and the mounting block 87 with the wire rope 11. Such a design ensures the sliding effect of the wire rope 11 while reducing the wear of the wire rope 11. In fact, measures to ensure the sliding effect and service life of the wire rope 11 can also be considered according to specific circumstances.

[0035] Preferably, magnets 92 are evenly installed on the pressing strip 9. Such a design enhances the compaction effect with the inner strip 10. In fact, measures to enhance the compaction effect with the inner strip 10 can also be considered according to specific circumstances.
