Description

Technical Field

[0001] The utility model belongs to the technical field of straw fermentation equipment, in particular to a straw feed fermentation barrel. Background Art

[0002] Straw bio-feed is made by inoculating a certain amount of specific non-toxic microorganisms to ferment and enzymolyze the straw, so that part of the straw is converted into sugars, lipids, proteins and other substances that can be used by animals. At the same time, some nutritional factors that the original straw did not have are added to improve the nutritional value and digestibility. The more successful straw bio-feeds include silage and micro-storage. Straw micro-storage is to add active microbial strains to crop straw, put it in a certain container or on the ground for fermentation, and after a certain fermentation process, the crop straw is turned into feed with sour, fragrant and wine-like flavors that livestock like to eat.

[0003] For straw micro-storage, the Chinese utility model patent with publication number CN220579250U proposes a fermentation barrel with automatic pressure relief, including a fermentation barrel, three evenly distributed hoops are fixedly sleeved on the outside of the fermentation barrel, the hoops and the fermentation barrel are made of the same material, two symmetrically distributed accommodating grooves are provided on the fermentation barrel, a barrel cover is threadedly connected to the fermentation barrel, an end cover is threadedly connected to the barrel cover, an exhaust pipe is fixedly sleeved in the barrel cover, and a pressure relief mechanism is provided on the exhaust pipe. This patent can use a compression spring to elastically press the piston into the exhaust pipe. When the air pressure in the fermentation barrel is too high, the gas in the fermentation barrel can be automatically discharged, so that the fermentation barrel can automatically relieve pressure to avoid safety hazards. However, in this patent, the exhaust pipe protrudes from the top of the barrel cover, making it difficult to stack the fermentation barrels. When the fermentation barrels are stacked vertically, other fermentation barrels cannot be stacked on the exhaust pipe at the top. If the fermentation barrels are stacked horizontally, the material in the fermentation barrel will lean towards the pressure relief mechanism, affecting the pressure relief. Therefore, when the fermentation barrel is used, it occupies a lot of space, resulting in space waste. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the deficiencies in the prior art and provide a straw feed fermentation barrel. This application provides the following technical solutions:

[0005] It includes a barrel body and a barrel cover installed on the top of the barrel body; a convex portion is provided at the bottom of the barrel body, and a concave portion is provided at the top of the barrel cover. When two fermentation barrels are stacked vertically, the convex portion of one fermentation barrel fits into the concave portion of the other fermentation barrel. A support plate and a pressure relief port are also provided on the barrel cover. The support plate is arranged across the concave portion, and the pressure relief port is located below the support plate.

[0006] Through the above arrangement, the pressure relief port is placed under the support plate. When two fermentation barrels are stacked vertically, the support plate supports the upper fermentation barrel without affecting the exhaust and pressure relief of the pressure relief port. At the same time, a convex portion is provided at the bottom of the barrel body and a concave portion is provided at the top of the barrel cover, so that the fermentation barrels are more stable after being stacked vertically.

[0007] An exhaust hole is provided on the side of the recess.

[0008] An exhaust hole is set. After the fermentation barrels are stacked, an exhaust channel is left for the pressure relief port of the fermentation barrel below. The gas discharged from the pressure relief port can flow to the outside from between the two fermentation barrels through the exhaust hole.

[0009] The recess includes a central depression and a flange located at an outer edge of the depression.

[0010] The inner side wall of the flange is matched with the outer side wall of the convex portion, the two ends of the support plate are connected to the flange, the exhaust hole is provided through the flange, and the pressure relief port is located in the recess.

[0011] Through the above arrangement, the structure of the barrel cover is more compact, and a gap is left at the bottom of the support plate. Therefore, when opening the barrel cover, force can be applied to the support plate to unscrew the barrel cover, which is convenient for applying force. At the same time, a rope can be passed through the bottom of the support plate, which makes it convenient to use the rope to lift the entire fermentation barrel for easy transportation.

[0012] A connecting piece is provided on the side of the barrel body, and the connecting piece is used to laterally connect adjacent fermentation barrels.

[0013] The connecting piece comprises a collar sleeved on the side of the barrel body, and the collar is provided with a clamping block and a clamping groove which can be longitudinally slidably matched.

[0014] By setting the collar, the middle part of the barrel body is reinforced. At the same time, the blocks and slots on the collar can be connected to each other to connect the horizontal fermentation barrels, so that multiple fermentation barrels can be stacked to form a whole and are not easy to fall. At the same time, the collar is set in a sleeve manner, which is convenient for connecting the blocks and slots, and will not affect the structure of the barrel body, which is convenient for production and manufacturing.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] By designing convex and concave parts and providing connectors on the barrel body, the stacking of fermentation barrels and the connection between fermentation barrels are facilitated. The stacked fermentation barrels have a stable structure and do not affect the pressure relief of the pressure relief port. There is no complicated design on the barrel body itself, the structure is simple, and the production cost is low.
