AI Technical Summary

Technical Problem

The existing membrane covering of manure fermentation tanks has low efficiency and cannot meet the high-frequency manure removal needs of modern farms. It requires multiple people to work together and takes a long time.

Method used

The system employs a motor-driven bidirectional threaded rod and connecting frame system to automatically lay the membrane. Combined with a membrane tension sensor and control box, it achieves smooth membrane coverage and recycling. At the same time, the system uses stirring blades and adjusting screws to break up the scum layer and expand the stirring range, promoting material homogenization.

Benefits of technology

It improves the efficiency of mulching and fermentation, reduces labor requirements, shortens mulching time, ensures the stability and ease of use of the membrane, and prevents manure crusting and acid accumulation.

Abstract

This utility model belongs to the field of manure fermentation technology, specifically a membrane-coated accelerated fermentation manure fermentation tank, comprising: a fermentation tank body, with a W-shaped guide plate and a porous aeration pipe arranged on the bottom surface of the fermentation tank body, symmetrically installed sliding rods inside the fermentation tank body, symmetrically opened support grooves on the inner wall of the fermentation tank body, and a first drive motor symmetrically installed on one side of the fermentation tank body, the output end of the first drive motor being fixedly connected to a bidirectional threaded rod; through the cooperation of the first drive motor, the bidirectional threaded rod, the connecting frame and the storage frame, one end of the membrane is driven to move along the top of the fermentation tank body, and the first support rods and connecting rings on both sides are driven to move along the sliding rods, stretching the two sides of the membrane, so that the membrane can more smoothly cover the top of the fermentation tank body, thereby improving the membrane coating efficiency of the fermentation tank body.
