[0023] Advantages

[0024] This utility model provides a pneumatic piston vibrating device for high-temperature koji production. This device reciprocates up and down, driving a hammer to repeatedly compress the koji material, replacing the traditional manual treading process to produce koji blocks from the trough. The pneumatic piston vibrating device is equipped with one shaft and four telescopic parts, for a total of five shafts, making the device operate more smoothly.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] In the present application, unless otherwise explicitly specified and limited, the first feature "on" or "below" the second feature can include that the first and second features are in direct contact, or it can include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature.

[0035] As shown in Figures 1 to 4 The present embodiment provides a pneumatic piston vibration device for high-temperature koji making process, which is driven by a cylinder to move up and down, simulates the artificial koji making process, and makes koji in the trough into koji blocks.

[0036] In some embodiments, the pneumatic piston vibration device 10 includes a crossbeam 1, a compression spring 2, a shaft 3, a telescopic portion 4, a fixed plate 5, a connecting plate 6 and a hammer head 7. The crossbeam 1 is located at the top of the pneumatic piston vibration device 10. The crossbeam 1 is a rectangular plate-like structure with a plurality of through holes on the top. The crossbeam 1 is fixedly connected to the cylinder (not shown in the figure). The cylinder not only provides power for the pneumatic piston vibration device 10, but also solves the problem of oil leakage and contamination of raw materials by the hydraulic cylinder in the prior art. One end of the shaft 3 passes through the through hole of the crossbeam 1 and is fixedly connected to the crossbeam 1. The shaft 3 can move up and down under the external force provided by the crossbeam 1. The compression spring 2 is sleeved on the outer periphery of the shaft 3. The shaft 3 provides support and limitation for the compression spring 2, so that the compression spring 2 can only move up and down along the shaft 3 under the action of external force. The compression spring 2 can provide elastic force for the crossbeam 1, so that the crossbeam 1 can return to its original position when it is not under the pressure of the cylinder. The compression spring 2 is used in conjunction with the cylinder to enable the pneumatic piston vibration device 10 to achieve up and down reciprocating motion, repeatedly beating the koji material, and simulating the manual treading process.

[0037] In some embodiments, one end of the telescopic portion 4 passes through the through hole of the crossbeam 1 and is connected to the crossbeam 1. The telescopic portion 4 is fixedly connected to the crossbeam 1 by a nut. This connection method facilitates the installation and disassembly of the pneumatic piston vibration device 10, and is also convenient for later maintenance and replacement of parts. The end of the shaft 3 and the telescopic portion 4 away from the crossbeam 1 is fixedly connected to the connecting plate 6, and the connecting plate 6 is provided with a plurality of through holes and exhaust holes 61. The end of the connecting plate 6 away from the telescopic portion 4 is connected to the hammer head 7, and the hammer head 7 is used to beat the bent material to form a bent block. The fixed plate 5 is provided with a plurality of through holes. The fixed plate 5 is sleeved on the outer periphery of the shaft 3 and the telescopic portion 4. The compression spring 2 is located between the crossbeam 1 and the fixed plate 5. The two ends of the compression spring 2 are respectively in contact with the crossbeam 1 and the fixed plate 5. When the shaft 3 and the telescopic portion 4 move up and down, the fixed plate 5 can ensure that the shaft 3 and the telescopic portion 4 always move up and down along their axial direction to prevent them from tilting, affecting the force applied to the bent material, causing the pressure on the bent material to be uneven, and affecting the quality of the bent block.

[0038] Furthermore, the telescopic portion 4 comprises a telescopic shaft 41 and a cylindrical body 42. The telescopic shaft 41 is a stepped shaft with a smaller diameter at each end than the diameter of the central projection. One end is threaded. The threaded end of the telescopic shaft 41 passes through the through-hole of the crossbeam 1. A nut secures the telescopic shaft 41 to the crossbeam 1, with the crossbeam 1 clamped between the nut and the projection of the telescopic shaft 41. A through-hole is defined in the center of the cylindrical body 42, whose dimensions match the diameter of the end of the telescopic shaft 41. The axis of the cylindrical body 42 is coaxial with the axis of the exhaust hole 61. When the crossbeam 1 is subjected to pressure from the cylinder, the beam 1 moves downward, driven by the beam 1 and moving into the cylindrical body 42 until the projection of the telescopic shaft 41 abuts the fixed plate 5. The gas in the cylindrical body 42 is then discharged through the exhaust hole 61. The pressure exerted on the crossbeam 1 is transmitted sequentially through the telescopic shaft 41, the fixed plate 5, the cylindrical body 42, and the connecting plate 6 to the hammer head 7, which compresses the bent material. When beam 1 is not under pressure, compression spring 2 provides elastic force for beam 1, causing beam 1 to move upward, driving shaft 3 and telescopic shaft 41 upward until compression spring 2 returns to its initial state and hammer 7 stops compressing the material. Through the above process, hammer 7 can repeatedly compress the material, simulating the process of manual bending, and forming a block of the material.

[0039] Furthermore, if Figure 3 and Figure 4 As shown, the hammer head 7 includes a blind hole 71 and a groove 72. The hammer head 7 is a hollow structure. The shape of the groove 72 is adapted to the shape of the curved block. A plurality of blind holes 71 are provided on the side of the hammer head 7 away from the groove 72. The blind holes 71 are provided with threads. Screws pass through the through holes of the connecting plate 6 and are screwed into the blind holes 71 to securely connect the connecting plate 6 to the hammer head 7. Preferably, the material of the hammer head 7 is polytetrafluoroethylene. Due to the non-stick properties of polytetrafluoroethylene, the hammer head 7 does not stick to the curved material during repeated beating, which is conducive to forming a complete curved block.

[0040] Optionally, the shape of groove 72 can be adapted to the desired koji block. In the present invention, the bottom cross-section of groove 72 is arc-shaped, matching the shape of Baobaoqu (a special type of koji used in the winemaking process). Baobaoqu is shaped like a raised bag on one wide side of a rectangular parallelepiped. This structure facilitates the growth and reproduction of microorganisms. Furthermore, this structure not only ensures compression but also significantly improves pulp extraction.

[0041] Optionally, the size of the hammer head 7 is 1.1-1.5 times that of a conventional hammer head, wherein the size of a conventional hammer head is generally 50mm to 60mm. A larger hammer head can process more koji material per compression, thereby improving production efficiency, and a larger contact area is conducive to the balance of slurry and water in the koji block and the overall looseness, allowing microorganisms to fully penetrate and grow in the koji block. At the same time, the weight of the conventional treaded koji is about 25kg. In the utility model, the weight of the treaded koji is increased to 1.1-2.2 times the weight of the conventional treaded koji, thereby increasing the impact force on the koji material and improving the density of the koji block.

[0042] Optionally, the barrel 42 is a column. Preferably, in this embodiment, the barrel 42 is a cylindrical body for ease of processing and manufacturing.

[0043] Optionally, at least one telescopic portion 4 is provided. Preferably, in this embodiment, four telescopic portions 4 are provided, which increases the stability of the pneumatic piston vibrating device 10. Compared with the single shaft of the prior art, the pneumatic piston vibrating device 10 operates more smoothly, and the compression force on the bent material is more balanced, thus avoiding the problem of uneven compression at the edges or corners of the bent block.

[0044] Optionally, the pneumatic piston vibrator 10 is connected to a controller (PLC) to adjust the vibration frequency of the pneumatic piston vibrator 10, thereby achieving automated production. By adjusting the vibration frequency of the pneumatic piston vibrator 10, the hammer head 7 repeatedly beats the koji material at a certain frequency, replacing the traditional manual treading process. This not only ensures uniform slurry discharge from the koji blocks and the stability of the slurry quality, but also reduces labor costs.

[0045] Working principle of the present invention: The pneumatic piston vibrating device 10 realizes reciprocating motion under the action of the cylinder and the compression spring 2, which can simulate manual stepping on the curved material, repeatedly compress the curved material, and make the curved material into a curved block. The cylinder applies pressure to the crossbeam 1, and the crossbeam 1 moves downward under the pressure. The shaft 3 and the telescopic shaft 41 move downward together with the crossbeam 1. The telescopic shaft 41 moves into the cylinder 42. The gas in the cylinder 42 is discharged through the exhaust hole 61. The compression spring 2 is compressed between the crossbeam 1 and the fixed plate 5. When the protrusion of the telescopic shaft 41 abuts the fixed plate 5, the crossbeam 1 stops moving downward. The pressure passes through the fixed plate 5, the cylinder 42 and the connecting plate 6 in sequence, and is then transmitted to the hammer head 7. The hammer head 7 compresses the curved material. When the cylinder no longer applies pressure to the crossbeam 1, the compression spring 2 provides elastic force for the crossbeam 1, causing the crossbeam 1 to move upward. The shaft 3 and the telescopic shaft 41 move upward together until the compression spring 2 returns to its initial state and the hammer head 7 no longer compresses the curved material. By controlling the reciprocating motion of the pneumatic piston vibrating device 10 , the hammer head 7 repeatedly compresses the bent material, replacing the traditional manual bending process, reducing labor costs, and forming the bent material into a bag-shaped curve consistent with the shape of the internal groove 72 of the hammer head 7 .

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
