Description

Technical Field

[0001] This utility model relates to the field of condiment processing equipment technology, and in particular to the auger assembly applied to a tumbler machine. Background Technology

[0002] In the process of soy sauce preparation, koji making is required, which includes a koji turning step. Usually, a soy sauce koji turning machine, as shown in publication number CN217743103U, is used. The koji is turned by a motor-driven auger assembly, thereby avoiding manual turning and improving the turning efficiency.

[0003] The aforementioned patents typically use a "tumbler assembly for a tumbler machine" as shown in publication number CN203764361U. A fixed stirring blade is provided at the bottom of the tumbler shaft. Even with the stirring blade, in actual use, due to the limitations of the tumbler machine and the height limitations on both sides, it is usually impossible to completely mix with the koji material at the bottom. A stable layer of about 30cm depth will form at the bottom of the koji material. This stable layer cannot be easily turned over and can only be manually processed after stopping the machine, which affects the quality of the koji material. Meanwhile, the bottom stirring plate, being pressed at the very bottom, bears the greatest pressure and is often easily damaged. The fixed installation, which cannot be disassembled, also makes it difficult to replace. Furthermore, the fixed setting limits the use of the turning machine and makes it unsuitable for use. Utility Model Content

[0004] This utility model provides an auger assembly for use in a koji turning machine, aiming to solve the problems mentioned above, such as the bottom stirring blades of the existing auger assembly used in koji turning machines not being able to fully contact the bottom of the koji tank, resulting in a stable layer forming at the bottom that cannot be turned up, affecting the quality of the koji, and the inability to disassemble and replace it, leading to poor applicability.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The auger assembly used in the turning machine includes an auger shaft and spiral blades. The spiral blades are fixedly arranged along the axial direction of the auger shaft and have cutting edges around their periphery. An elastic telescopic member is elastically installed at the bottom end of the auger shaft. A bottom blade is detachably fixedly installed at the end of the elastic telescopic member away from the auger shaft. The bottom blade is axially elastically installed with the bottom end of the auger shaft through the elastic telescopic member and rotates synchronously. The elastic telescopic member is in a compressed state during use.

[0006] Preferably, the elastic telescopic member includes a cylindrical body with an opening at only one end, and a plurality of limiting blocks are provided at equal intervals around the outer side of the cylindrical body, all of which extend radially outward.

[0007] More preferably, the limiting block is integrally formed with the cylinder.

[0008] More preferably, there are at least two limiting blocks.

[0009] More preferably, the bottom end of the auger shaft is provided with a sliding groove corresponding to the cylinder, and a limiting groove corresponding to the limiting block is provided around the sliding groove, and the limiting grooves are all connected to the sliding groove.

[0010] Furthermore, the cylinder opening is embedded in the sliding groove to form an axial sliding fit, the limiting block forms a limiting fit in the corresponding limiting groove, and the cylinder forms a coaxial synchronous rotation fit with the auger shaft through the limiting block.

[0011] Furthermore, a spring is provided between the cylinder and the sliding groove. One end of the spring is located in the limiting groove, and the other end of the spring is located inside the cylinder. The cylinder and the sliding groove form an axial elastic fit through the spring.

[0012] Specifically, the bottom blades of the pool include a fixed disk, a connecting shaft is coaxially arranged in the middle of the fixed disk, and a number of stirring blades are arranged at equal intervals around the connecting shaft.

[0013] More specifically, the fixed plate has several concealed screw holes around the shaft, and the bottom of the cylinder has mounting screw holes that correspond one-to-one with the concealed screw holes. When the mounting screw holes correspond to and are connected with the concealed screw holes, a concealed thread fit is formed by the corresponding concealed screw.

[0014] More specifically, all the stirring blades are arranged at an angle.

[0015] The beneficial effects of this utility model are: (1) This utility model utilizes an elastic telescopic component to apply a reaction force to the bottom blades of the pool without affecting the rotation. The top of the auger shaft is fixed to the motor. Therefore, under the reaction force of the spring, the bottom blades of the pool are pushed down towards the bottom of the koji pool, thereby inserting into the bottom stable layer, turning the material up to break the stable layer, forming a more uniform stirring, ensuring the quality of the koji, and improving the turning efficiency. (2) As long as the compression can be maintained within the range of flexible installation, the device can be implemented on the koji pool that meets the conditions, thereby improving the applicability of the koji turning machine itself; (3) The bottom blades can be disassembled and installed as a whole, making it convenient to replace and repair.

[0017] The embodiments will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-6 As shown, in a preferred embodiment 1, the auger assembly applied to the tumbling machine includes an auger shaft 1 and a spiral blade 2. The spiral blade 2 is fixedly arranged along the axial direction of the auger shaft 1, and the spiral blade 2 is provided with a cutting edge 3 around its periphery. An elastic telescopic member 4 is elastically installed at the bottom end of the auger shaft 1. A bottom blade 5 is detachably fixedly installed at the end of the elastic telescopic member 4 away from the auger shaft 1. The bottom blade 5 is axially elastically installed with the bottom end of the auger shaft 1 through the elastic telescopic member 4 and rotates synchronously at the same time. The elastic telescopic member 4 is in a compressed state during use.

[0019] The compressed state causes the elastic telescopic component 4 to have a reaction force away from the auger shaft 1. Therefore, during use, the elastic telescopic component 4 always tends to move away from the auger shaft 1, thereby pushing the bottom blade 5 downwards, so that the bottom blade 5 inserts into the stable layer at the bottom of the material and rotates synchronously with the auger shaft 1, breaking the stable layer and turning up the bottom material, thus achieving the purpose of thorough mixing. At the same time, the bottom blade 5 is detachable, which facilitates disassembly and replacement in the face of the high probability of wear and tear of the bottom blade 5, thereby improving the overall work efficiency.

[0020] The elastic telescopic member 4 includes a cylindrical body 401 with only one end open. A plurality of limiting blocks 402 are provided at equal intervals around the outer side of the cylindrical body 401, and the limiting blocks 402 all extend radially outward.

[0021] There are at least two limit blocks 402 to ensure the stability of the limit.

[0022] The bottom end of the auger shaft 1 is provided with a sliding groove 101 corresponding to the cylinder 401. The sliding groove 101 is surrounded by a limiting groove 102 corresponding to the limiting block 402. All the limiting grooves 102 are connected to the sliding groove 101.

[0023] The cylinder 401 is embedded in the sliding groove 101 with its opening facing the sliding groove 101 to form a sliding fit along the axial direction. The limiting block 402 forms a limiting fit in the corresponding limiting groove 102, and the cylinder 401 forms a coaxial synchronous rotation fit with the auger shaft 1 through the limiting block 402.

[0024] A spring 403 is provided between the cylinder 401 and the sliding groove 101. One end of the spring 403 is located in the limiting groove 102, and the other end is located in the cylinder 401. The cylinder 401 and the sliding groove 101 form an axial elastic fit through the spring 403. Under the limiting action of the limiting block 402, the cylinder 401 rotates synchronously with the auger shaft 1 to achieve a stirring effect. At the same time, it has the function of limiting sliding, so that the cylinder 401 tends to move away from the auger shaft 1 under the force of the spring 403. The cylinder 401 will always slide in the direction away from the sliding groove 101, and finally stop after the bottom blade 5 touches the bottom of the pool.

[0025] The bottom blades 5 include a fixed disk 501, with a connecting shaft 502 coaxially arranged in the middle of the fixed disk 501. A plurality of stirring blades 503 are evenly spaced around the connecting shaft 502. The cylinder 401 rotates synchronously with the auger shaft 1, and the fixed disk 501 rotates synchronously with the cylinder 401, driving the connecting shaft 502 to rotate synchronously, ultimately causing the stirring blades 503 to rotate around the shaft to turn the material.

[0026] The fixed plate 501 has several concealed screw holes 504 arranged around its shaft, and the bottom of the cylinder 401 has mounting screw holes 404 that correspond one-to-one with the concealed screw holes 504. When the mounting screw holes 404 correspond to and connect with the concealed screw holes 504, a concealed thread engagement is formed by the corresponding concealed screw 505. This ensures stable installation and reduces the impact of fasteners on the curved material.

[0027] All the stirring blades 503 are arranged at an angle. This facilitates the scooping up of the material in the stable layer during rotation, so as to mix and stir it with the material above.

[0028] In a preferred embodiment 2, there are two limiting blocks 402, which are arranged symmetrically about the central axis of the cylinder 401. This ensures the stability of limiting and synchronous rotation.

[0029] In a preferred embodiment 3, the limiting block 402 is integrally formed with the cylinder 401, facilitating overall replacement.

[0030] In a preferred embodiment 4, the number of stirring blades 503 is four.

[0031] In a preferred embodiment 5, the stirring blade 503, the fixed disk 501, and the connecting shaft 502 are integrally formed, facilitating complete replacement.

[0032] The working principle of this utility model: This utility model utilizes the elastic telescopic component 4 to apply a reaction force to the bottom blade 5 of the pool without affecting the rotation. The top of the auger shaft 1 is fixed to the motor. Therefore, under the reaction force of the spring 403, the bottom blade 5 of the pool is pushed downward toward the bottom of the koji pool, thereby inserting into the bottom stable layer, turning the material upward to break the stable layer, forming a more uniform stirring, ensuring the quality of the koji, and improving the turning efficiency. As long as the spring 403 can maintain compression within a certain range, the device can be implemented on any material pool that meets the conditions, thereby improving the applicability of the turning machine itself. The bottom tank blades 5 can be completely disassembled and installed, making them easy to replace and repair.
