DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] The utility model provides a feed fermentation bag, comprising a bag body 1. Figure 1 As shown, the top of the bag body 1 is fixedly connected to the feed pipe 6 and penetrates a vent pipe 2. Figure 2As shown, the air permeable tube 2 is a vertical I-shaped tube, which passes through the top of the bag body 1 and is sealed and fixedly connected to the bag body 1. The top distal end of the air permeable tube 2 is located outside the bag body 1 and is in sealed contact with the top outer surface of the bag body 1. The bottom distal end of the air permeable tube 2 is located inside the bag body 1 and is in sealed contact with the top inner wall of the bag body 1, ensuring that external gas does not enter the bag body 1 from the connection between the air permeable tube 2 and the bag body 1.

[0022] The vent tube 2 is detachably slidably inserted into a cylindrical plug 5, which is sealed and slidably connected to the vent tube 2. The top of the cylindrical plug 5 is coaxially connected to the circular plate 4. The top of the circular plate 4 is coaxially fixedly connected to the knob 3, and the circular plate 4 can be rotated by turning the knob 3. The bottom of the circular plate 4 is in sealed rotational contact with the top end face of the cylindrical plug 5, ensuring that the air outside the bag body 1 cannot enter the bag body 1 through the gap between the circular plate 4 and the cylindrical plug 5. Figure 3 As shown, an air cavity is dug out in the cylindrical plug 5. An air outlet hole 15 is drilled on the top of the cylindrical plug 5, and a plurality of through holes 14 are drilled on the bottom of the cylindrical plug 5. The air outlet hole 15 connects the air cavity with the outside of the cylindrical plug 5. Each through hole 14 connects the air cavity with the inside of the bag body 1. An exhaust hole 7 is drilled on the circular plate 4, and the exhaust hole 7 connects to the outside of the bag body 1 and is connected to the air outlet hole 15 in a docking manner to form a gas flow channel for convenient exhaust.

[0023] like Figure 2 As shown, a one-way valve 11 is fixedly installed in the exhaust hole 7, and the one-way valve 11 controls the air in the bag body 1 to flow out, and the air outside the bag body 1 cannot flow in.

[0024] like Figure 2 and Figure 3 As shown, a first limiting assembly is welded and fixed on the outer circumferential curved surface at the top of the cylindrical plug 5. The first limiting assembly is located outside the bag body 1 and is in contact-limited cooperation with the top distal end of the vent tube 2. The first limiting assembly includes a limiting block, which is rectangular and has two blocks, and the two limiting blocks are opposite to each other about the central axis of the cylindrical plug 5. Two limiting grooves are cut on the distal end of the top of the cylindrical plug 5, and the two limiting grooves correspond to the two limiting blocks one by one. Each limiting block is in contact-limited cooperation with the corresponding limiting groove, and is used to fix the cylindrical plug 5.

[0025] A second stopper is installed in the air cavity of the cylindrical plug 5. The second stopper is located in the bag body 1 and is in contact with the bottom distal end of the air permeable tube 2. The second stopper includes a first clamping block 8, which is a cross-shaped slider. The first clamping block 8 passes through the plug body of the cylindrical plug 5 along the radial direction of the cylindrical plug 5 and is in contact with the plug body of the cylindrical plug 5. The first clamping block 8 is in contact with the bottom distal end of the air permeable tube 2 and is used to fix the cylindrical plug 5.

[0026] The transmission assembly is assembled in the air cavity of the cylindrical plug 5, and the circular plate 4 is matched with the first clamping block 8 through the transmission assembly, which is used to drive the first clamping block 8 to slide through the plug body of the cylindrical plug 5 along the radial direction of the cylindrical plug 5. The transmission assembly includes a second clamping block 9 and a rotating shaft 10. The rotating shaft 10 is coaxially connected to the cylindrical plug 5. The top of the rotating shaft 10 passes through the top plug body of the cylindrical plug 5 and is sealed and rotatably connected with the plug body to ensure that external air does not enter the bag body 1 from the connection between the rotating shaft 10 and the cylindrical plug 5. The top of the rotating shaft 10 is coaxially fixedly connected with the circular plate 4. The second clamping block 9 is welded and fixed on the rotating shaft 10. The second clamping block 9 is an arc block, and the center of the arc is located on the central axis of the rotating shaft 10. The second clamping block 9 is fixedly connected to the rotating shaft 10 through a connecting rod. A push block is welded on the top of the first clamping block 8, and the second clamping block 9 and the push block on the top of the first clamping block 8 are both slidably abutted and transmission matched.

[0027] A fixing plate 13 is placed inside the cylindrical plug 5, and the fixing plate 13 is fixedly connected to the cylindrical plug 5. A spring 12 is fixedly connected to the fixing plate 13, and the spring 12 is arranged along the radial direction of the cylindrical plug 5. The end of the spring 12 away from the fixing plate 13 is fixedly connected to the first clamping block 8 for resetting the first clamping block 8.

[0028] Working principle: When in use, a certain amount of feed is filled into the bag body 1 through the feed pipe 6 for fermentation, and the feed pipe 6 is blocked after the filling is completed. The blocking technology is an existing technology and will not be described in detail here. At the same time, the cylindrical plug 5 is coaxially inserted into the air-permeable tube 2 until the limit block on the cylindrical plug 5 is inserted into the limit groove on the air-permeable tube 2 and forms a limit clamping connection with the limit groove.

[0029] At this time, the knob 3 is rotated, the knob 3 drives the circular plate 4 to rotate, the circular plate 4 drives the rotating shaft 10 to rotate, the rotating shaft 10 drives the second block 9 to revolve around the rotating shaft 10, the second block 9 pushes the push block on the first block 8 to move away from the central axis of the cylindrical plug 5, and the push block drives the first block 8 to slide out of the cylindrical plug 5 along the radial direction of the cylindrical plug 5 until the push block abuts against the inner wall of the cylindrical plug 5, and the first block 8 contacts the vent pipe 2 and forms a limited abutment. In this process, the spring 12 is compressed.

[0030] When the first block 8 contacts the vent pipe 2 and forms a limited contact, the exhaust hole 7 on the circular plate 4 is connected to the exhaust hole 15 on the cylindrical plug 5. During the feed fermentation process, since the fermented bacteria produce a large amount of waste gas, the gas in the bag body 1 gradually increases and the air pressure increases and is greater than the air pressure outside the bag body 1. The waste gas in the bag body 1 passes through the through hole 14, the air cavity, the exhaust hole 15 and the exhaust hole 7, and finally is discharged through the one-way valve 11.

[0031] If the cylindrical plug 5 is to be removed, the knob 3 only needs to be twisted in the reverse direction, and the spring 12 is stretched at this time, and the first clamping block 8 is reset and slid back under the elastic force of the spring 12. Thereafter, the cylindrical plug 5 can be pulled out.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
