Detailed Implementation

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0020] This application provides a protective structure for a fermentation tank, such as... Figures 1-4 As shown, the structure includes: fermentation tank 1, arc plate 2, mounting rod 3, connecting rod 4, and protective cover 5.

[0021] Among them, such as Figure 1 As shown, the upper part of the fermentation tank 1 is cylindrical, and the middle part of the tank is rounded to increase the capacity of the fermentation tank 1. The lower part of the fermentation tank 3 gradually tapers inward to the bottom of the tank, which makes it easier for workers to insert the stirring pestle along the inner wall of the fermentation tank 1 into the bottom of the fermented soybean paste to stir it, thus reducing the labor intensity of workers. An installation groove 11 is provided on the outer side of the upper part of the fermentation tank 1 along the circumference of the tank opening.

[0022] likeFigure 2 As shown, there are two arc-shaped plates 2. One end of the two arc-shaped plates 2 is rotatably connected, with its rotation axis pointing towards the height direction of the arc-shaped plate 2. The other end of the two arc-shaped plates 2 is provided with a support plate 21. The two support plates 21 are connected by bolts. When the two support plates 21 are connected, the two arc-shaped plates 2 form a ring that fits the mounting groove 11. That is, the ring formed by the two arc-shaped plates 2 can be nested in the mounting groove 11. The two arc-shaped plates 2 are rotatably connected at one end, and the other end is connected by a support plate 21 and bolts, which simplifies the installation and disassembly process of the arc-shaped plates 2 and improves the convenience of installation and disassembly of the protective structure.

[0023] like Figure 2 As shown, one end of the mounting rod 3 is connected to the convex surface of the arc plate 2, and the axis of the mounting rod 3 is perpendicular to the central axis of the ring formed by the two arc plates 2. Correspondingly, after the arc plate 2 is installed in the mounting groove 11, the axis of the mounting rod 3 is perpendicular to the central axis of the opening of the fermentation tank 1.

[0024] like Figures 2-4 As shown, an annular groove 33 is coaxially formed on the body of the mounting rod 3. One end of the connecting rod 4 is rotatably fitted in the annular groove 33, and its rotation axis is coaxial with that of the mounting rod 3. A pin 41 is provided at the far end of the connecting rod 4. The pin 41 is parallel to the mounting rod 3 and is set toward the arc plate 2.

[0025] like Figures 1-3 As shown, the protective cover 5 includes a ring-shaped cover body 51. A mesh 52 is provided at the upper end of the cover body 51. A mating block 53 is formed on the convex surface of the cover body 51. The mating block 53 has a positioning groove 54 that is adapted to the mounting rod 3. An arc-shaped groove 55 is provided on the end face of the mating block 53. The arc-shaped groove 55 passes through one side of the mating block 53 and is located above the mounting rod 3. The shape of the arc-shaped groove 55 is adapted to the movement path of the pin 41.

[0026] When applying, such as Figures 1-3 As shown, two arc-shaped plates 2 are installed in the mounting groove 11, and the protective cover 5 is placed on top of the fermentation tank 1, with the positioning groove 54 on the mating block 53 aligned with the mounting rod 3. Then, the protective cover 5 is placed on the tank opening, and the connecting rod 4 is rotated so that the pin 41 at the far end of the connecting rod 4 enters the arc-shaped groove 55 from one side of the mating block 53. Correspondingly, the end of the arc-shaped groove 55 is a predetermined distance away from the other side of the mating block 53, so that after the pin 41 enters the end of the arc-shaped groove 55, the connecting rod 4 is biased to the other side of the mating block 53. Thus, under the action of the connecting rod 4 and the pin 41, the pin 41 will not slip out from the end of the arc-shaped groove 55, thereby fixing the protective cover 5. The mesh 52 at the tank opening completely covers the tank opening and will not slip off, which has high reliability and good protective effect.

[0027] Specifically, such as Figures 1-4As shown, the first positioning groove 54 is a U-shaped through groove opened at the bottom of the end face of the fitting block 53, and the first positioning groove 54 is arranged along the height direction of the cover body 51 and penetrates the inner side of the cover body 51, and the groove width of the first positioning groove 54 is equal to the diameter of the mounting rod 3. When installing the protective cover 5, the first positioning groove 54 can be directly aligned with the mounting rod 3, so that the mounting rod 3 enters the first positioning groove 54, and the installation process of the protective cover 5 is further simplified through the cooperation of the mounting rod 3 and the first positioning groove 54, and the convenience of installation of the protective structure is improved.

[0028] Specifically, as shown in the drawings, Figure 3 As shown, the gauze 52 has elasticity; when the mounting rod 3 is located in the first positioning groove 54 and the gauze 52 naturally abuts the cylinder port of the fermentation cylinder 1, the mounting rod 3 is at a predetermined distance from the bottom of the positioning groove 54, and the distance between the end of the arc-shaped groove 55 and the mounting rod 3 is greater than the distance between the pin rod 41 and the mounting rod 3. At this time, when the pin rod 41 is turned to the end of the arc-shaped groove 55, because the distance between the end of the arc-shaped groove 55 and the mounting rod 3 is greater than the distance between the pin rod 41 and the mounting rod 3, the pin rod 41 will move along the convex surface of one side of the arc-shaped groove 55, and the fitting block 53 and the cover body 51 will be lowered, and the gauze 52 has elasticity, so that when the fitting block 53 and the cover body 51 are lowered, the gauze 52 will be pressed against the edge of the cylinder port, and the gauze 52 will be in complete contact with the cylinder port, completely blocking the path for mosquitoes to enter, and further improving the protection effect of the protective structure; at the same time, through the cooperation of the first positioning groove 54 and the mounting rod 3 and the cooperation of the pin rod 41 and the arc-shaped groove 55, the rotation of the protective cover 5 around the central axis of the cylinder port and the movement of the protective cover 5 along the height direction of the fermentation cylinder 1 are effectively limited, so that the protective structure has high stability; when disassembling, the pin rod 41 only needs to be pulled out, and then the protective cover 5 can be removed, which is convenient for workers to remove the protective cover 5 to stir the bean paste, and has high convenience.

[0029] Preferably, as shown in the drawings, Figures 1-3 The number of mounting rods 3 is two, and each is arranged on the corresponding arc-shaped plate 2, and the axes of the two mounting rods 3 are coaxially arranged; the number of fitting blocks 53 is two, and each is located at the diameter of the cover body 51, so that the diameter of the cover body 51 of the protective cover 5 can be installed and fixed, so that the gauze 52 is uniformly stressed and the protection performance is guaranteed.

[0030] Specifically, as shown in the drawings, Figure 4 and Figure 5As shown, the upper part of the protective cover 5 is further provided with a cylinder cover 6, the bottom of the cover body is annular, the top is conical, a second positioning groove 61 adapted to the mounting rod 3 is formed in the cover body of the cylinder cover 6, the second positioning groove 61 is a U-shaped through groove formed below the cover body of the cylinder cover 6, the second positioning groove 61 is arranged along the height direction of the cylinder cover 6, and the groove width is equal to the diameter of the mounting rod 3. The bottom of the cover body of the cylinder cover 6 is provided with a pin hole 62, the pin hole 62 is located above the second positioning groove 61, a moving ring 31 is slidably sleeved on the mounting rod 3, the moving ring 31 is provided with a bolt 32 parallel to the mounting rod 3, the bolt 32 is arranged towards the arc-shaped plate 2, and the bolt 32 is adapted to the pin hole 62. The cooperation mode of the second positioning groove 61 and the mounting rod 3 is the same as that of the first positioning groove 54 and the mounting rod 3, so that the cylinder cover 6 can be quickly positioned to the mounting position, when the mounting rod 3 abuts against the bottom of the second positioning groove 61, the moving ring 31 is moved along the mounting rod 3 to the arc-shaped plate 2, and the bolt 32 is inserted into the pin hole 62, so that the installation of the cylinder cover 6 is completed, and correspondingly, as shown in Figure 4 and Figure 5 As shown, the outer thread can be arranged on the mounting rod 3, and then the top ring 7 is screwed in, so that the moving ring 31 is clamped on the outer side of the cylinder cover 6, thereby realizing the reinforcement of the cylinder cover 6, and playing the role of rainproof and windproof.

[0031] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. Obviously, those skilled in the art can make various modifications and changes to the present application without departing from the spirit and scope of the present application.
