Silage pit

Abstract

The invention belongs to the field of silage facilities, and particularly discloses a silage pit. The silage pit includes a pit body which is arranged on and under the ground, and further includes an air bag, a cover plate and a ventilation pipe; the pit body is cylindrical, sealing films are arranged on the side wall of the pit body and the bottom face of pit body in an attached mode, the side wall of the pit body is provided with a cylinder-shaped interlayer, the sealing film on the side wall is located between the interlayer and the pit body, the interlayer is provided with an air channel and a plurality of air branch passages, and the air branch passages are all communicated with the air channel; a plurality of air holes are formed in one face, away from the sealing file on the side wall, of the interlayer, the air holes are communicated with the air branch passages, and each hole is connected with a balloon in a sealed mode; lactic acid bacteria are placed in each balloon, the upper portion of the interlayer is provided with threads, the cover plate is connected with the interlayer through the threads, the air channel and an air bag are communicated through the ventilation pipe, and the air bag is provided with an extrusion structure. According to the silage pit, the sealing environment of silage can be ensured, and it is convenient to add the lactic acid bacteria, so that the fermentation of the silage is ensured.

Description

technical field [0001] The invention relates to the field of silage facilities, in particular to a silage pit. Background technique [0002] The purpose of the silo is to bury the green fodder to ferment. The silage feed is isolated from the air, produces organic acids, is not bad for a long time, and can reduce the loss of nutrients. Not only will the nutrients in silage not decrease, but it also has an aromatic and sour taste, which stimulates the appetite of livestock, increases feed intake, and has a good effect on promoting the growth and development of mutton sheep. And silage is an affordable way to preserve green fodder. Silage can maximize the total nutrients harvested per unit area and reduce the waste of nutrients. In addition, it is convenient to realize mechanized harvesting, transportation and storage, reduce labor intensity and increase work efficiency. [0003] Silos are usually excavated in the ground. In the prior art, building the silage pond will sel...

Problems solved by technology

Therefore, during the fermentation process, it is difficult for lactic acid bacteria to quickly form a dominant flora and cannot reduce the pH value in a short time

The results: First, all kinds of bacteria are growing and multiplying, causing the temperature to rise rapidly, resulting in the extension of the pre-fermentation period

The second is that during the preparatory fermentation process, the silage will lose a lot of nutrients and energy due to heat, and also cause a pungent smell and poor palatability.

The third is the massive reproduction of mold and spoilage bacteria during the fermentation process, resulting in partial mildew and rot in the silage, especially the top, bottom and edge mildew and rot.

Fourth, due to the existence of a large number of miscellaneous bacteria, it is easy to form secondary fermentation when the silage is opened, and new mold spots or moldy patches will appear on the feeding section. If the situation is not good, it will cause complete mildew and rot
