[0041] This application provides a koji-making cage device to solve at least one of the following technical problems in the traditional koji-making cage method, which involves on-site manufacturing and assembly, or on-site assembly of the frame followed by welding of stainless steel plates: (1) complex construction process, large amount of installation work, and high labor intensity for workers; (2) slow on-site construction progress, low construction efficiency, and high on-site manufacturing cost; (3) difficulty in accurately controlling the on-site manufacturing quality and appearance. The koji-making cage device will be described below with reference to the accompanying drawings.

[0042] The fermentation cage device 10 provided in this application embodiment is exemplary; please refer to [link to example]. Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of the koji-making cage device 10 provided in the embodiments of this application. The koji-making cage device 10 of this application can be used for koji making.

[0043] To more clearly illustrate the structure of the fermentation cage device 10, the following description of the fermentation cage device 10 will be provided in conjunction with the accompanying drawings.

[0044] For example, please refer to Figure 1As shown, a koji-making cage device 10 includes a support component 100, a fixing component 200, and a wall component 300. The support component 100 is used for embedding in the working site 20. The fixing component 200 includes several shaping plates 210 and several connecting plates 220. Each shaping plate 210 is used to be installed on its corresponding support component 100. Connecting plates 220 are respectively connected to adjacent support components 100. The connecting plates 220 are positioned by the shaping plates 210. The multiple connecting plates 220 are spliced ​​to form a closed structure. The wall component 300 includes multiple wall panels 310. Each wall panel 310 is respectively connected to the connecting plate 220. The multiple wall panels 310 are spliced ​​to form a cage. The cage has a closed structure, and since the cage is installed on the connecting plates 2220, the closed structure formed by the cage and the connecting plates 220 is consistent. It should be noted that the closed structure mentioned above refers to a polygonal ring formed by connecting multiple connecting plates 220 one after the other in sequence. The more connecting plates 220 there are, the closer the closed structure is to a circle.

[0045] The fermentation cage device 10 in this application adopts a modular design and is manufactured in a factory prefabrication method. The support component 100, the fixing component 200 and the wall component 300 are prefabricated. During installation, the support component 100, the fixing component 200 and the wall component 300 can be assembled. On-site assembly is fast, the installation positioning is accurate and the assembly efficiency is high.

[0046] When installing the aforementioned koji-making cage device 10, if the support component 100 is embedded in the working site 20, holes can be drilled in the working site 20, the support component 100 can be inserted into the holes, and then sealed and fixed with concrete. Alternatively, the support component 100 can be fixed in the working site 20 first, and then concrete can be poured to encase the support component 100.

[0047] In some embodiments, the multiple connecting plates 220 may be polygonal, so the cage may have a polygonal structure, such as octagonal, dodecagonal, hexagonal, etc.

[0048] In some implementations, see Figure 2 As shown, Figure 2 This is a schematic diagram of the support component 100 of the koji-making cage device 10 according to an embodiment of this application. The support component 100 includes multiple embedded parts 110 for installation in the working environment 20 and a support platform 120. Each embedded part 110 is connected to a support platform 120. Each shaping plate 210 is installed on its corresponding support platform 120. A connecting plate 220 is connected to its corresponding support platform 120. The support platform 120 can improve the support stability and provides a certain area of ​​installation space, which facilitates the installation of the shaping plate 210 and the connecting plate 220.

[0049] In some embodiments, the embedded component 110 includes a plurality of embedded rods 111. The plurality of embedded rods 111 of each embedded component 110 are spaced apart. A support platform 120 is connected to the plurality of embedded rods 111 of the corresponding embedded component 110. That is, one embedded component 110 is connected to one support platform 120, and each embedded component 110 includes a plurality of embedded rods 111. The plurality of embedded rods 111 can distribute the stress on the support platform 120, and the plurality of embedded rods 111 can support the support platform 120 at multiple angles, improving support stability.

[0050] In some embodiments, the plurality of embedded rods 111 of each embedded component 110 may be arranged in a matrix. For example, the plurality of embedded rods 111 may be arranged in multiple rows and columns. For example, when each embedded component 110 contains four embedded rods 111, the four embedded rods 111 may be arranged in two rows and two columns.

[0051] In some embodiments, the embedded rod 111 is embedded along its length in the working area 20. The top of the embedded rod 111 protrudes beyond the working area 20. This protrusion of the top of the embedded rod 111 facilitates the installation of the support platform 120. During actual installation, the length of the top of the embedded rod 111 protruding beyond the working area 20 should not be too large, just enough so that the bottom surface of the support platform 120 can contact the surface of the working area 20.

[0052] In some embodiments, the end of the embedding rod 111 used for embedding is bent. The bent end of the embedding rod 111 can increase the contact stress with the embedding site 20, improve the connection between the embedding rod 111 and the site 20, improve the stability of the support component 100, and also improve the stability of the entire cage.

[0053] In some embodiments, the support platform 120 is positioned horizontally relative to the work site 20 during installation.

[0054] In some implementations, see Figure 3 As shown, Figure 3 This is a schematic diagram showing the cooperation between the support member 100 and the fixing member 200 of the koji-making cage device 10 according to one embodiment of this application. The number of connecting plates 220 can be 8, 12, 16, or other numbers. The number of connecting plates 220 can be set according to the radial dimension of the cage. Generally speaking, the more connecting plates 220 there are, the more support members 100 are required, and the closer the resulting polygonal closed structure is to a circle.

[0055] In some embodiments, at least two shaping plates 210 are mounted on the top surface of each support platform 120. See also Figure 4 As shown, Figure 4This is a partial structural diagram of the supporting member 100 and the fixing member 200 of the koji-making cage device 10 according to an embodiment of this application after they are engaged. Two shaping plates 210 are spaced apart and form positioning slots 230 extending along the curve of the closed structure. The two opposite ends of the connecting plate 220 are respectively located within two adjacent positioning slots 230 and positioned by the positioning slots 230. The purpose of the positioning slots 230 is to position the connecting plate 220. Since the two ends of the connecting plate 220 are respectively located on two adjacent supporting platforms 120, positioning the ends of the connecting plate 220 through the positioning slots 230 facilitates precise installation of the connecting plate 220, which in turn facilitates the precise positioning and installation of the subsequent wall panel 310.

[0056] In some implementations, see Figure 4 As shown, the support platform 120 is provided with a first positioning hole. The end of the connecting plate 220 is provided with a second positioning hole 221 that matches the first positioning hole. The connecting plate 220 and the support platform 120 are detachably connected by fasteners passing through the first positioning hole and the second positioning hole 221. The first positioning hole and the second positioning hole 221 are also used for positioning between the connecting plate 220 and the support platform 120, improving installation accuracy.

[0057] In some implementations, see Figure 4 As shown, the support platform 120 is provided with a third positioning hole. Each shaping plate 210 is provided with a fourth positioning hole 211. The shaping plate 210 and the support platform 120 are detachably connected by fasteners passing through the third positioning hole and the fourth positioning hole 211. The third positioning hole and the fourth positioning hole 211 are also used for positioning between the shaping plate 210 and the support platform 120, improving installation accuracy.

[0058] In some implementations, see Figure 5 As shown, Figure 5 This is a partial structural diagram of the koji-making cage device 10 according to one embodiment of this application. The wall component 300 further includes multiple wall frames 320. The wall frames 320 are mounted on the connecting plate 220. Wall frames 320 are respectively provided at both ends of the connecting plate 220 along the curve direction of the closed structure. Wall panels 310 on the connecting plate 220 are located between corresponding wall frames 320 and connected to them. The wall panels 310 are connected through the wall frames 320, and the wall frames 320 enhance the stability and sealing of the cage.

[0059] In some embodiments, the wall panel 310 and the connecting plate 220 are connected by welding. Welding can quickly connect the wall panel 310 and the connecting plate 220, improve the strength of the connection, and enhance the stability and sealing of the cage.

[0060] In some embodiments, the wall panel 310 and the wall frame 320 are connected by welding. Welding can quickly connect the wall panel 310 and the wall frame 320, improve the connection strength, and enhance the stability and sealing of the cage.

[0061] In some embodiments, two wall frames 320 on the same support member 100 are connected by welding. It is easy to understand that in other embodiments, the two wall frames 320 can also be sealed together in other ways.

[0062] In some embodiments, the connecting plate 220 and the support member 100 are also connected by welding. Welding can quickly achieve the connection between the connecting plate 220 and the support member 100, improve the connection strength, and enhance the stability and sealing of the cage.

[0063] In some embodiments, at least one wall is provided with a window 311. The window 311 can be used for operations such as feeding and observation.

[0064] In some embodiments, the materials used to prepare the support component 100, the fixing component 200, and the wall component 300 can be metal, stainless steel, or composite materials, as long as they meet the requirements for koji making.
