[0028] Please see the appendix Figures 1-5 The purpose of this embodiment is to provide a novel fermentation pit cover that can rise and fall with the material inside the pit. It includes: a pit cover body, which has an arc-shaped top plate 2, a first side plate 3, and a second side plate 6. Both the first and second side plates are inclined towards the top plate 2. A vertical plate 21 is provided below the pit cover body, extending vertically from the top plate 2, the first side plate 3, and the second side plate 6. A sealing square tube 1 is attached to the outer side of the vertical plate 21. In this embodiment, the first and second side plates have the same inclination angle of 30°. Because the top plate 2 is arc-shaped and the side plates 3 and 6 are inclined, the overall internal shape of the pit cover is closer to the shape of the material, reducing the cavity between the material and the cover, allowing the cover to better contact the material, and further improving the fermentation effect.

[0029] Specifically, the vertical plate 21 is rectangular in shape, and its thickness is the same as that of the top plate 2 of the pit cover, the first side plate 3 of the pit cover, and the second side plate 6 of the pit cover. Furthermore, the outer and inner perimeters of the rectangle formed by the vertical plate 21 are equal to the outer and inner perimeters of the rectangle formed by the lower edges of the top plate 2, the first side plate 3, and the second side plate 6. A sealing square tube 1 surrounds the vertical plate 21, completely enclosing it; the lower surface of the sealing square tube 1 is flush with the lower surface of the vertical plate 21. Compared with existing technologies, when operating on pits of the same size, because the sealing steel tube 1 is attached to the outside of the vertical plate 21 and its lower surface is flush with the lower surface of the vertical plate 21, it does not occupy the internal space of the pit cover, thus increasing the maximum amount of material fermentation in the pit and ensuring close contact between the material and the pit cover, thereby improving the fermentation effect. In addition, the sealing steel pipe 1 is attached to the outside of the vertical plate 21, which reduces the overall manufacturing cost of the cover when operating on the same size pit. The sealing square tube 1 is a hollow tube, which further reduces the manufacturing cost.

[0030] In this embodiment, the top plate 2 of the fermentation pit cover is provided with several crisscrossing ribs 10, which improves the overall strength of the fermentation pit cover and extends its service life. The top plate 2 of the fermentation pit cover is also provided with multiple quick-access sampling ports 4 and multiple lifting lugs 5. The overhead crane in the workshop can quickly lift the pit using the lifting lugs 5, and the quick-access sampling ports 4 facilitate sampling and testing. Furthermore, the top plate 2 of the fermentation pit cover, the first side plate 3 of the fermentation pit cover, and the second side plate 6 of the fermentation pit cover are all made of 304 or 316L stainless steel brushed plate; the sealing square tube 1, the quick-access sampling ports 4, and the lifting lugs 5 are all made of 304 or 316L stainless steel. This not only improves the strength of the fermentation pit cover but also meets food hygiene requirements.

A vertical plate 21 is provided below the pit cover body, extending vertically from the top plate 2, the first side plate 3, and the second side plate 6. A sealing square tube 1 is attached to the outer side of the vertical plate 21. In this embodiment, the first and second side plates have the same inclination angle of 40°. Because the top plate 2 is arc-shaped and the first and second side plates are inclined, the overall internal shape of the pit cover is closer to the shape of the material, reducing the cavity between the material and the cover, allowing the cover to better contact the material, and further improving the fermentation effect.

[0033] Specifically, the vertical plate 21 is rectangular in shape, and its thickness is the same as that of the top plate 2 of the pit cover, the first side plate 3 of the pit cover, and the second side plate 6 of the pit cover.

In addition, the sealing steel pipe 1 is attached to the outside of the vertical plate 21, which reduces the overall manufacturing cost of the cover when operating on the same size pit. The sealing square tube 1 is a hollow tube, which further reduces the manufacturing cost.

[0034] In this embodiment, the top plate 2 of the fermentation pit cover is provided with several crisscrossing ribs 10, which improves the overall strength of the fermentation pit cover and extends its service life. The top plate 2 of the fermentation pit cover is also provided with multiple quick-access sampling ports 4 and multiple lifting lugs 5.

This not only improves the strength of the fermentation pit cover but also meets food hygiene requirements.

[0035] In use, the material is placed in the fermentation pit, and the pit cover is placed on top of the fermenting material, with the pit cover itself positioned within the pit. Sealing mud 7 is filled into the gap between the sealing square tube 1 of the pit cover and the side wall 8 of the pit, completely covering the sealing square tube 1 and adhering to the vertical plate 21. Using sealing mud 7 for sealing is simple and provides good sealing. When materials are added or removed from the pit, and the pit cover is placed back on the fermenting material, the position of the pit cover within the pit will rise or fall accordingly.
