Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a rapid film covering mechanical device for greenhouse planting. Background Technique

[0002] Machinery is a tool device that can help people reduce the work difficulty or save effort. Items such as chopsticks, brooms, and tweezers can all be called machinery. They are simple machinery, and complex machinery is composed of two or more simple machineries. Usually, these relatively complex machineries are called machines. From the perspectives of structure and motion, there is no difference between mechanisms and machines, and they are generally referred to as machinery.

[0003] When planting in existing greenhouses, it is often necessary to cover the planted plants with a film. However, when covering the film, the film cannot be in an unfolded state. When the film is in a wrinkled and folded state, this will not only have a great impact on the film covering effect. Although it can be unfolded manually, this will waste a certain amount of manpower. Therefore, the utility model proposes a rapid film covering mechanical device for greenhouse planting to solve the above-mentioned problems. Content of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1:

[0026] Please refer to Figures 1 - 5 , the present invention is a rapid film covering mechanical device for greenhouse planting, including a support plate 1. Four support rods 2 are fixedly installed on the lower end surface of the support plate 1. Installation grooves 3 are opened at the bottom ends of the four support rods 2. A moving wheel 4 is rotatably connected inside the installation groove 3. The moving wheel 4 is used to make the entire device in a moving state. A square through groove 21 is opened on the upper end surface of the support plate 1 and between two mounting plates 5. The inner side surface of the square through groove 21 is set as an arc surface 22. The arc surface 22 is used to effectively ensure that the film can be normally transmitted. A connecting sleeve opening is opened on the side end surface of the support plate 1 to facilitate the pulling of the device by a farm vehicle;

[0027] Two symmetrically arranged mounting plates 5 are fixedly installed on the upper end surface of the support plate 1. A rotating shaft 6 is rotatably connected between the two mounting plates 5. A winding roller 7 is fixedly installed on the rotating shaft 6. Annular plates 23 are fixedly installed on the rotating shaft 6 and outside the winding roller 7. The number of the annular plates 23 is two and they are symmetrically arranged. The annular plates 23 are used to ensure that the film is in a normal unwinding state;

[0028] A guiding mechanism is provided on the lower end surface of the support plate 1 and inside the support rod 2. The guiding mechanism includes two positioning plates 8 and two support plates 9 fixedly installed on the support plate 1. The support plates 9 are located on one side of the positioning plates 8. A driving shaft 10 is rotatably connected between the two positioning plates 8. A guiding roller 11 is fixedly installed on the driving shaft 10. An annular groove 12 is formed on the side end surface of the guiding roller 11. A connecting shaft 13 is rotatably connected between the two support plates 9. A pressing wheel 14 is fixedly installed at one end of the connecting shaft 13 away from the support plate 9. The edge portion of the film is pressed into the inside of the annular groove 12 by the pressing wheel 14. The side corners of the pressing wheel 14 and the side corners of the annular groove 12 are chamfered to avoid causing certain damage to the film. Moreover, the pressing wheel 14 and the guiding roller 11 are made of rubber to further improve the film pressing effect.

[0029] In this embodiment, the film on the winding roller 7 is stretched onto the guiding roller 11, so that the films on both side edges of the film are inside the annular groove 12. Then, through the pressing of the pressing wheel 14, the stretched film is in an unfolded state, enabling the film to always have the maximum area coverage and effectively improving the planting efficiency.

[0030] Embodiment 2:

[0031] Please refer to Figures 1 - 5 , on the basis of Embodiment 1, an adsorption assembly is provided on the lower end surface of the support plate 1 and on one side of the guiding mechanism. The adsorption assembly is used to keep the film in an unfolded state. The adsorption assembly includes a support block 15 fixedly installed on the upper end surface of the support plate 1 and two side plates 16 fixedly installed on the lower end surface of the support plate 1. The side plates 16 are located on the other side of the positioning plates 8. An air suction fan 17 is fixedly installed on the support block 15. An air inlet pipe 18 is fixedly connected to the input end of the air suction fan 17. An adsorption pipe 19 is fixedly installed between the two side plates 16. An adsorption port 20 is formed on the upper end surface of the adsorption pipe 19. The end of the air inlet pipe 18 away from the air suction fan 17 penetrates the support plate 1 and is fixedly connected to the adsorption pipe 19. The film does not completely cover the adsorption port 20. By using the suction force of the air suction fan 17, it is ensured that the film adheres to the adsorption pipe 19.

[0032] In this embodiment, when the film passes through the guiding roller 11, the air suction fan 17 in the adsorption assembly is started. Through the connection between the air inlet pipe 18 and the adsorption pipe 19, the adsorption port 20 on the adsorption pipe 19 is used to prevent the film from being wrinkled, keeping the film smooth and stable and improving the use effect of the film.

[0033] Working principle:

[0034] In use, it is installed on the agricultural vehicle by using the connecting socket on the support plate 1. The whole device is pulled by the agricultural vehicle. Then, the film on the winding roller 7 is stretched to the guiding roller 11, then pulled under the winding roller 7, and then passed above the adsorption tube 19. During this process, the film is in contact with the guiding roller 11 and the adsorption tube 19.

[0035] When the film is on the guiding roller 11, the film at the two side edges of the film is placed inside the annular groove 12. Then, through the pressing of the pressing wheel 14, the stretched film is in an unfolded state, so that the film is always in a state of maximizing the area coverage.

[0036] When the film is on the adsorption tube 19, the suction fan 17 is started. Through the connection between the air inlet pipe 18 and the adsorption tube 19, the adsorption port 20 on the adsorption tube 19 is used to prevent the film from being wrinkled, so that the film remains smooth and stable, improving the use effect of the film.

[0037] In the technical solution, the input ends of the electrical devices in the equipment are all electrically connected to an external power source.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
