Description

Silage bag and storage system capable of automatically and remotely monitoring pH value in corn silage

Technical Field

The invention relates to the technical field of silage processing, in particular to a silage bag and a storage system for automatically and remotely monitoring the pH value in a corn silage.

Background

The corn silage is a feed product formed by performing anaerobic fermentation on the straws and grains of the corn in a proper growth period, has the advantages of maximizing the available nutrient substances of the straws and the grains of the harvested corn, and has the following specific effects:

the loss rate of the nutrient components of the feed in the ensiling process is between 5 and 15 percent, and the loss rate of the dried nutrient components is between 30 and 50 percent.

The silage can keep the juice of the feed, the water content of the hay is 14% -17%, the water content of the silage can reach about 70%, digestion of raw animals is facilitated, and the palatability is good.

The silage occupies small space, has high density, is not easy to cause accidents such as fire because of high water content, and is safe to store.

The pH value is rapidly reduced in the ensiling process, so that pests and germs can be killed, the pests and eggs cannot survive due to the lack of oxygen and high acidity, harmful germs are killed or inhibited in the environment by the competition of beneficial bacteria, and weeds are utilized by ensiling.

Corn ensiling comprises the following processes:

and (3) oxygen affinity: some biochemical systems in plants are still working where the ear corn is broken up and placed into silage chambers (which may also be purpose-made silage bags or silage towers). Plant enzymes degrade soluble sugars into carbon dioxide and water, converting proteins into amino acids and amines. These reactions destroy nutrients and reduce the amount of beneficial fermentation enzymes, and excessive heat generation at this stage can lead to browning reactions, which can reduce carbohydrate content and protein digestibility in the plant. Therefore, the time for the aerobic phase should be minimized and the transition to the next ensiling phase should be made as soon as possible.

Ensiling and fermenting: the anaerobic acid-producing bacteria fermentation will last for approximately one to two weeks. Factors affecting silage fermentation are: sugar and dry matter content in the silage raw material, bacterial type and quantity, bacterial activity, processing balance, silage pit type and silage technology. In a natural state, the ratio of the quantity of the ensiled harmful microorganisms to the quantity of the beneficial microorganisms on the surface of the plant is about 10: 1, and if the biochemical process of the ensiled crops is natural, the nutrition loss quantity in the ensiled crops is large due to the action of relatively more harmful microorganisms in the initial fermentation stage, mainly expressed as high ratio of ammoniacal nitrogen to total nitrogen, so that the protein loss is caused. The harmful microorganisms also produce butyric acid, the increase of the butyric acid causes the deterioration of the smell of the feed, the palatability is poor, the feed is not beneficial to the ingestion of livestock, and the fermentation process is not easy to be effectively controlled. Beneficial bacterium strains of lactic acid bacteria are artificially added, so that the relative quantity of the beneficial bacteria is increased, the lactic acid bacteria quickly reach the dominant high quantity in an anaerobic environment, the fermentation process is accelerated, a large amount of lactic acid is quickly generated, the pH value is quickly reduced, the activity of harmful microorganisms is inhibited, and the aim of preserving nutrition is fulfilled, therefore, the use of a proper silage additive is very important in the silage process.

And (3) a stabilization stage: the fermentation microorganism can gradually utilize and absorb the soluble sugar in the plants. The acidity of the silage material is reduced to ph 3.5-4.5. At this time, the biochemical activity of the silage substance is greatly reduced, and the silage substance enters a stabilization stage. This stage must be anaerobic.

A discharging stage: the silage kiln is opened and the silage is exposed to oxygen and the silage begins to degrade. The heat and assimilable nutrients in the silage are lost. The temperature is increased by 10 ℃, the dry matter loss of the exposed part per day reaches about 3 percent, so the exposed surface and the exposure time are reduced as much as possible.

Need monitor the pH value of maize silage during maize silage to in time adjust the environment pH value of maize silage, guarantee the product quality of output maize silage.

A clamping space for clamping and fixing the bottom of the bag body 4 is formed between the two clamping plates 10. The maximum width of the groove body of the first limit groove 7 is smaller than the minimum bottom width of the cover shell 1, so that the cover shell 1 can be stably placed on the base 6.

In this embodiment, the first limiting block 8 is guided to move downward in the first limiting groove 7, so that the first limiting block 8 applies downward pressure to one end of the swing rod 9 through the upper groove wall of the second limiting groove 12, and the other end of the swing rod 9 drives the clamp plate 10 to rotate towards the housing 1, thereby driving the two clamp plates 10 to approach each other to clamp and fix the housing 1.
