after the straw fermentation in the fermentation chamber 23 is completed, the methane amount in the fermentation chamber 23 is greatly reduced, so that the air pressure is reduced, under the action of the spring 58, the piston 56 moves to the right, the piston 56 drives the push plate 43 to move to the right through the piston rod 59, so that the push plate 43 pushes the spline wheel 41 to move to the right, the spline wheel 41 is in spline connection with the spline chamber 76, the auxiliary motor 40 drives the spline wheel 41 to rotate through the flat key, the spline wheel 41 drives the auxiliary belt wheel 42 to rotate through the spline, the auxiliary belt wheel 42 drives the lead screw 30 to rotate through the V belt 39, the lead screw 30 drives the extrusion push plate 37 to move to the right through the threaded connection, so as to extrude the straw in the fermentation chamber 23 and push the two left stirring wheels 27 to move to the right, because the elastic coefficient of the torsion spring 22 is large, the filter chamber door 24 is opened after the straw is extruded to a certain degree, and the liquid generated by the straw extrusion flows, after the filter box door 24 is opened, the extrusion push plate 37 conveys the extruded straws into the storage cavity 34 at the upper side of the filter plate 29 for storage,
then the auxiliary motor 40 is reversed to drive the extrusion push plate 37 to move leftwards to reset, the two stirring wheels 27 on the left side move leftwards to reset under the action of the compression spring 28, then the auxiliary motor 40 stops rotating, due to the reduction of the air pressure in the fermentation cavity 23, the auxiliary piston 67 moves rightwards to reset under the action of the reset spring 65, the inclined plane block 62 moves rightwards to reset, the inclined plane block 62 pushes the limiting rod 60 to move downwards to reset, then the electromagnet 57 is electrified to adsorb the piston 56 to move leftwards, the piston 56 pushes the inclined plane limiting block 72 to move upwards firstly, then the piston 56 moves leftwards to the left side of the inclined plane limiting block 72, then under the action of the auxiliary reset spring 71, the inclined plane limiting block 72 moves downwards to reset, then the electromagnet 57 is de-electrified, under the action of the spring 58, the piston 56 is abutted against the left end,
the extruded straw residue can then be removed by manually opening the airtight chamber door 33, and the fermented liquid can be recovered by opening the solenoid valve 36.
The invention has the beneficial effects that: the straw crushing mechanism can directly convey the crushed straw into the fermentation tank, the crushing and conveying processes are carried out in the sealed container, so that dust pollution is avoided, the stirring device in the fermentation mechanism can stir the straw, the release of biogas by the straw is accelerated, the biogas detection mechanism can automatically judge whether the straw is fermented, and after the straw is fermented, the extrusion conveying mechanism extrudes the fermented straw to remove water, the straw residue is conveyed to a storage position for storage, so that the fermentation liquor and the straw residue are automatically separated, the processing process of the invention is basically free of dust pollution, and the fermentation liquor and the straw residue can be automatically separated after the fermentation is finished.
In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
