Description

Technical Field

[0001] The utility model relates to the technical field of compost fermentation, and particularly relates to a film covering device for a compost air flow film. Background Technique

[0002] Film-covered composting is a form of artificially intervened composting, which is a composting method of covering a special film-covered tarpaulin on the surface of the compost pile. The film material has the functions of waterproofing and air permeability. By forced ventilation, a "slightly positive pressure" is formed in the compost pile, and the fermentation is uniform without forming an anaerobic zone. Combining the characteristics of the microporous film, the odor emission is greatly reduced, creating an excellent "climate box" for the composting materials, so that they are not affected by the external weather.

[0003] In the Chinese patent with the publication number CN218710049U, a film covering device for compost fermentation is disclosed. Through the combined use of an adjusting component and a clutch transmission component, the first gantry can be reversely moved for winding. After the winding is completed, only the second gantry needs to be lifted to separate the first gear from the second gear, so that the wound nano film can be quickly moved, effectively improving the storage speed and greatly improving the mobility of film covering, and greatly improving the film covering efficiency.

[0004] However, after the traditional film covering device finishes film covering, the air flow film is sealed around the edge of the compost tank, which is not conducive to the opening of the compost tank, resulting in that the staff cannot effectively detect the fermentation situation.

[0019] 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 making creative efforts belong to the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention discloses a film covering device for a composting airflow film, including a gantry 1 fixed at one end of a composting tank 3, and also including an unwinding roller 6. The unwinding roller 6 is rotatably installed on one side of the gantry 1, and an airflow film 7 is wound on the unwinding roller 6. One end of the airflow film 7 is provided with a limiting plate 8. Preferably, the limiting plate 8 is evenly provided with ground inserting piles for fixing the limiting plate 8 at the end of the composting tank 3 away from the gantry 1.

[0021] The film covering device for a composting airflow film provided in this embodiment further includes a support frame 2. The support frame 2 is fixed on the side of the gantry 1 facing the composting tank 3, and a first pressing plate 4 is slidably installed vertically on the support frame 2. The first pressing plate 4 slides downward and abuts against the upper surface of the composting tank 3, so as to realize the compaction and limitation of the airflow film 7 near the support frame 2.

[0022] In addition, the film covering device for a composting airflow film provided in this embodiment further includes a connecting frame 10. The connecting frame 10 is located on both sides of the composting tank 3, and the connecting frame 10 is slidably arranged between the gantry 1 and the support frame 2. Second pressing plates 9 are fixed at the lower ends of the two connecting frames 10. The second pressing plates 9 are used to limit the movement of the airflow film 7 between the gantry 1 and the support frame 2. The second pressing plates 9 can slide on the airflow film 7, so as to control the tension of the airflow film 7 between the first pressing plate 4 and the second pressing plate 9.

[0023] In the present scheme, the airflow film 7 is covered on the compost trough 3 by pulling the limit plate 8. In this process, the airflow film 7 near the support frame 2 is compacted and limited by the first pressure plate 4 to improve the stability of the airflow film 7 after coating. The second pressure plate 9 is driven to move by the connecting frame 10. When the second pressure plate 9 is close to the first pressure plate 4, the airflow film 7 is in a relaxed state. The airflow film 7 can be rolled up by the unwinding roller 6, so that one end of the compost trough 3 is opened, which is beneficial for the staff to detect the fermentation situation inside the compost trough 3. When the second pressure plate 9 is away from the first pressure plate 4, the second pressure plate 9 pulls the airflow film 7 to completely cover the compost trough 3, thereby realizing the closure of the compost trough 3.

[0024] like Figures 1-3 As shown, the connecting frame 10 provided in this embodiment is an inverted "L" shaped structure, and a screw rod 11 is rotatably installed between the gantry 1 and the support frame 2. The screw rod 11 is threadedly connected to the connecting frame 10, and the connecting frame 10 is driven to move by the screw rod 11.

[0025] In order to improve the stability of the connecting frame 10 during movement, a guide rod 12 is fixed between the gantry 1 and the support frame 2. The guide rod 12 is slidably connected to the connecting frame 10. The sliding connection between the guide rod 12 and the connecting frame 10 improves the stability of the connecting frame 10 during movement to ensure that the connecting frame 10 slides along the direction of the guide rod 12.

[0026] like Figure 2 one Figure 4 As shown, in order to realize the driving of the screw rod 11, a transmission box 14 is installed on the inner side of the gantry 1, a dual-axis motor 16 is fixed inside the transmission box 14, a transmission shaft 17 is installed at the output end of the dual-axis motor 16, and a first bevel gear 18 is installed at one end of the transmission shaft 17 away from the dual-axis motor 16. One end of the two screw rods 11 extends into the transmission box 14 and is installed with a second bevel gear 19, and the second bevel gear 19 is meshed with the first bevel gear 18.

[0027] In this solution, the transmission shaft 17 is rotated by the dual-axis motor 16, and the first bevel gear 18 is further rotated synchronously with the transmission shaft 17. The first bevel gear 18 is meshed with the second bevel gear 19, so that the second bevel gear 19 drives the screw rod 11 to rotate.

[0028] like Figure 1 and Figure 3 As shown, in order to facilitate the stability of the first pressure plate 4 when in contact with the airflow film 7, anti-slip grooves are provided on the lower surface of the first pressure plate 4 to increase the friction between the airflow film and the first pressure plate 4, thereby improving the stability of the airflow film 7 after coating, and sliding notches are provided at both ends of the first pressure plate 4 for sliding connection with the support frame 2 to facilitate pulling the first pressure plate 4 up and down.

[0029] like Figure 1 andFigure 3 As shown in the figure, to drive the lifting of the first pressing plate 4, the support frame 2 provided in this embodiment has an "H" shape, and a cylinder 15 is installed on the support frame 2, and the cylinder 15 is used to drive the lifting of the first pressing plate 4.

[0030] As Figures 1-3 As shown in the figure, to facilitate the driving of the unwinding roller 6, side plates 13 are symmetrically fixed to the outer upper end of the gantry 1. The other end of the side plate 13 is fixedly connected to the support frame 2, and the side plate 13 is connected to the unwinding roller 6 by bearings. A driving motor 5 for driving the rotation of the unwinding roller 6 is fixed to the outside of one of the side plates 13.

[0031] The working principle and usage process of the present utility model: When in use, place the gantry 1 at one end of the composting tank 3, so that the support frame 2 faces the direction of the composting tank 3. Drive the unwinding roller 6 to rotate through the driving motor 5 to realize the unwinding of the air flow film 7. At this time, pull the limiting plate 8 to move towards the other end of the composting tank 3 and fix the limiting plate 8 on the ground, thereby realizing the film covering of the composting tank 3.

[0032] Start the cylinder 15 to drive the lifting of the first pressing plate 4, and compact and limit the air flow film 7 near the support frame 2 through the first pressing plate 4 to improve the stability of the air flow film 7 after film covering, thereby realizing the stable film covering of the composting tank 3 between the first pressing plate 4 and the limiting plate 8.

[0033] Start the double-shaft motor 16, make the transmission shaft 17 rotate through the double-shaft motor 16, and further make the first bevel gear 18 rotate synchronously with the transmission shaft 17. Through the meshing of the first bevel gear 18 and the second bevel gear 19, make the second bevel gear 19 drive the lead screw 11 to rotate. Through the threaded connection between the lead screw 11 and the connecting frame 10, make the connecting frame 10 slide on the guide rod 12, and further drive the second pressing plate 9 to move, so as to control the tension degree of the air flow film 7 between the first pressing plate 4 and the second pressing plate 9.

[0034] When the second pressing plate 9 approaches the first pressing plate 4, at this time the air flow film 7 is in a relaxed state, and the air flow film 7 can be wound up through the unwinding roller 6, so that one end of the composting tank 3 is opened, which is beneficial for the staff to detect the fermentation situation inside the composting tank 3. When the second pressing plate 9 moves away from the first pressing plate 4, at this time the second pressing plate 9 pulls the air flow film 7 to completely cover the composting tank 3, thereby realizing the closing of the composting tank 3.
