Description

Technical Field

[0001] This utility model relates to a membrane uncovering device, and in particular to a membrane composting uncovering device applied in the field of aerobic fermentation treatment technology. Background Technology

[0002] The most commonly used technology in the livestock and poultry farming industry is aerobic composting. After mixing livestock and poultry manure with auxiliary materials and microbial agents, the mixture is placed in the composting site, covered with a functional membrane, and a porous pipe is laid at the bottom of the fermentation tank. The material pile is ventilated and oxygenated by the blower and the pipe, which avoids the manual or mechanical consumption of turning the pile and also reduces environmental pollution to a certain extent.

[0003] At the beginning and end stages of membrane-based aerobic fermentation, membrane removal and re-covering operations are required respectively. In the past, the membrane removal and re-covering were mainly carried out by manual dragging. However, manual dragging not only requires the cooperation of many people, which is time-consuming and labor-intensive, but the functional membrane is also prone to friction and scratches with the ground during the dragging process, which can easily damage the functional membrane and shorten its service life. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that the initial and final stages of membrane-covered aerobic fermentation require membrane removal and membrane covering operations, respectively. However, the existing membrane removal and covering methods are still carried out by manual dragging, which is not only time-consuming and labor-intensive, but also easily damages the functional membrane and shortens its service life.

[0005] To address the aforementioned problems, this utility model provides a membrane composting uncovering device, comprising a stack wall fixedly connected to the upper end of the composting site and two guide rails disposed on the upper end of the stack wall. A support frame is provided at the upper end of the guide rails, and a drive wheel is rotatably connected within the support frame. A drive motor is fixedly connected to the lower end of the support frame, and a drive reducer is fixedly connected to one end of each of the two drive motors. The output shaft of the drive motor movably passes through the support frame and is fixedly connected to the drive wheel. Multiple auxiliary frames are also provided at the upper end of the guide rails, and pulleys are rotatably connected within the auxiliary frames. Both the drive wheel and the pulleys are slidably connected to the guide rails. The upper ends of the auxiliary frame and the two support frames are fixedly connected to fixed brackets. A guide component is fixedly connected between two adjacent fixed brackets. A positioning frame is fixedly fitted on the outer surface of the fixed bracket. A functional membrane is fixedly connected between two adjacent positioning frames. Multiple rotating brackets are rotatably connected inside the rightmost fixed bracket. A shielding membrane is fixedly connected between two adjacent rotating brackets. A sealing motor is fixedly connected to the upper end of the support frame. A sealing reducer is fixedly connected to one end of each of the two sealing motors. The output end of the sealing motor moves through the fixed bracket and is fixedly connected to the multiple rotating brackets.

[0006] The above-mentioned membrane composting membrane uncovering and covering device can perform membrane uncovering and covering operations at the beginning and end stages of membrane-based aerobic fermentation. By moving multiple support brackets, the functional membrane is driven to fold and extend, thereby uncovering the compost membrane. No manual dragging is required, which saves time and effort. During the membrane uncovering process, the functional membrane does not rub or scrape against the ground, thus effectively extending the service life of the functional membrane.

[0007] As a further improvement of this application, a controller is also fixedly connected to the upper end of the composting yard. The drive motor, drive reducer, sealing motor and sealing reducer are all connected to the controller via signal. The controller is located on the left side of the stack wall.

[0008] As a further improvement to this application, a ventilation duct is excavated at the upper end of the composting yard, and the ventilation duct is located inside the stack wall.

[0009] As a further improvement of this application, the lower end of the guide rail is fixedly connected to the upper end of the pier wall, the two guide rails are relatively parallel, and the two guide rails are on the same horizontal plane.

[0010] As another improvement of this application, the guide assembly includes four adjusting blocks that are slidably connected to adjacent fixed supports, and adjusting rods are rotatably connected to the multiple adjusting blocks. The adjusting rods are X-shaped.

[0011] In summary, in practical applications, the controller controls the drive motor to move the rightmost fixed bracket forward, pulling multiple fixed brackets on the left to cover the compost with the functional film. When the drive wheel reaches the front limit, the sealing motor activates, causing the rotating bracket to rotate. The rotation stops when the rotating bracket reaches its lower limit, completing the film covering operation. When the film needs to be removed, the controller controls the sealing motor to rotate the rotating bracket. The rotation stops when the rotating bracket reaches its upper limit, and the drive motor activates, moving the rightmost fixed bracket and pushing multiple fixed brackets on the left to peel off the functional film. The film removal operation stops when the film reaches its end limit. This eliminates the need for manual dragging, saving time and effort. During the film removal process, the functional film does not rub or scratch against the ground, effectively extending its service life. Attached Figure Description
