Description

Technical Field

[0001] This utility model relates to the field of feeding chute technology, specifically to a feeding chute assembly based on steamed rice husks. Background Technology

[0002] Rice husks are an indispensable solid filler and leavening agent in baijiu brewing. They provide space support for the fermentation of mash, help maintain the oxygen content and looseness of the mash, and promote the smooth progress of processes such as steaming, saccharification and fermentation.

[0003] Traditionally, rice husks accelerate down the chute and may splash everywhere when they reach the discharge port. This not only pollutes the environment around the production equipment but may also cause the rice husk particles to break, affecting the quality of the rice husks and their subsequent use.

[0004] Therefore, it is necessary to design a feeding chute assembly based on steamed rice husks to solve the aforementioned technical problems. Utility Model Content

[0005] This utility model provides a feeding chute assembly based on steamed rice husks. It is configured with two semi-circular plates and a fixed block in a protective ring frame, and a rotating rod in a limiting groove. Then, a torsion spring sleeved on the rotating rod makes each semi-circular plate have rotational elasticity. When materials such as rice husks are fed, the semi-circular plates rotate under the pressure of the materials, which plays a role in buffering the feeding speed and uniform feeding, thereby improving the feeding efficiency.

[0006] The technical solution provided by this utility model is as follows: A feeding chute assembly based on rice husk steaming includes: The chute body has a first fixing ring at its discharge end, and a second fixing ring is detachably connected to the lower side of the first fixing ring. A protective ring frame is provided on the lower side of the second fixing ring. Two semicircular plates are symmetrically arranged inside the protective ring frame, and a fixing block is installed on the outer side of each semicircular plate. Limiting grooves are respectively opened on both sides of the inner wall of the protective ring frame. A rotating rod is rotatably connected inside each limiting groove, and the rotating rod is rotatably connected to the fixing block. Two torsion springs are symmetrically sleeved on the rotating rod, and the two ends of each torsion spring are respectively connected to the outer side of the fixing block and the inner side wall of the limiting groove.

[0007] Furthermore, it also includes screws. The first fixing ring and the second fixing ring are respectively provided with a first threaded hole and a second threaded hole along their circumference. The screw passes through the first threaded hole on the first fixing ring and the second threaded hole on the second fixing ring in sequence and is fixed.

[0008] Furthermore, a through hole is provided on one side of the inner wall of the limiting groove, and one end of the rotating rod is rotatably connected to the through hole.

[0009] Furthermore, the protective ring frame is symmetrically provided with two auxiliary parts on its exterior. Each auxiliary part includes a hexagonal post and a fixed frame. The end of the rotating rod, which is rotatably connected to the through hole, is provided with a hexagonal groove that matches the hexagonal post. One end of the hexagonal post is installed inside the hexagonal groove, and the other end of the hexagonal post is connected to the fixed frame.

[0010] Furthermore, the fixed frame is slidably connected with a locking block, and the outer side of the protective ring frame is provided with a locking groove that matches the locking block, with one end of the locking block engaging in the locking groove.

[0011] Furthermore, guide blocks are respectively installed on both sides of the card block, and a guide groove adapted to the guide block is opened inside the fixed frame, and the guide block is slidably connected to the guide groove.

[0012] Furthermore, the interior of the protective ring frame is equipped with an inclined annular guide frame.

[0013] Furthermore, a through groove adapted to the rotating rod is provided on one side of the fixing block, and the rotating rod is rotatably connected in the through groove.

[0014] The beneficial effects of this utility model are: The first and second fixing rings at the feeding end of the chute body are fixed by screws, which facilitates the connection and disassembly of the feeding chute assembly with other equipment or components, making installation, commissioning and subsequent maintenance and repair work easier, and reducing maintenance costs and difficulty. The protective ring frame installed on the lower side of the second fixed ring can protect the two internal semi-circular plates, reduce the direct impact and wear of materials such as rice husks on them during the feeding process, extend the service life of the components, and at the same time, the protective ring frame can prevent external debris from entering to a certain extent, ensuring the smooth feeding process. The two semicircular plates inside the protective ring frame are rotatably engaged with the rotating rod via a fixed block, and a torsion spring is fitted on the rotating rod. The torsion spring gives the semicircular plates a certain degree of rotational elasticity: when materials such as rice husks are fed, the semicircular plates can rotate appropriately under the pressure of the materials, which can buffer the feeding speed and ensure uniform feeding, avoiding problems such as blockage or uneven feeding caused by feeding too fast; after the material feeding is completed, the semicircular plates can automatically reset under the action of the torsion spring, which is convenient for the next feeding, thereby realizing and improving feeding efficiency.

[0019] like Figures 1 to 5 As shown, a feeding chute assembly based on steamed rice husks includes a chute body 1. A first fixing ring 2 is provided at the feeding end of the chute body 1, and a second fixing ring 3 is detachably connected to the lower side of the first fixing ring 2. A protective ring frame 4 is provided on the lower side of the second fixing ring 3. Two semi-circular plates 5 are symmetrically arranged inside the protective ring frame 4, and a fixing block 18 is installed on the outer side of each semi-circular plate 5. Limiting grooves 6 are respectively opened on both sides of the inner wall of the protective ring frame 4. A rotating rod 7 is rotatably connected inside each limiting groove 6, and the rotating rod 7 is rotatably connected to the fixing block 18. Two torsion springs 8 are symmetrically sleeved on the rotating rod 7, and the two ends of each torsion spring 8 are respectively connected to the outer side of the fixing block 18 and the inner side wall of the limiting groove 6.

[0020] As a further technical solution of this embodiment, it also includes a screw 19. The first fixing ring 2 and the second fixing ring 3 are respectively provided with a first threaded hole 201 and a second threaded hole 301 along their circumference. The screw 19 passes through the first threaded hole 201 on the first fixing ring 2 and the second threaded hole 301 on the second fixing ring 3 in sequence and is fixed, which facilitates the installation and disassembly of the first fixing ring 2 and the second fixing ring 3.

[0021] As a further technical solution of this embodiment, a through hole is provided on one side of the inner wall of the limiting groove 6, and one end of the rotating rod 7 is rotatably connected to the through hole, which facilitates the rotation of the rotating rod 7 and makes full use of the space.

[0022] As a further technical solution of this embodiment, the protective ring frame 4 is symmetrically provided with two auxiliary parts 20 on its exterior. Each auxiliary part 20 includes a hexagonal column 11 and a fixed frame 12. The end of the rotating rod 7, which is rotatably connected in the through hole, is provided with a hexagonal groove 10 that matches the hexagonal column 11. One end of the hexagonal column 11 is installed inside the hexagonal groove 10, and the other end of the hexagonal column 11 is connected to the fixed frame 12. The fixed frame 12 is slidably connected with a locking block 14. The outer side of the protective ring frame 4 is provided with a locking groove 16 that matches the locking block 14. One end of the locking block 14 is locked in the locking groove 16. Guide blocks 15 are respectively installed on both sides of the locking block 14. The fixed frame 12 is provided with a guide groove 13 that matches the guide block 15. The guide block 15 is slidably connected to the guide groove 13.

[0023] In this embodiment, the hexagonal column 11 is movably installed in the hexagonal groove 10 at the end of the rotating rod 7, so that the two are matched in shape and form a rigid linkage structure. When the hexagonal column 11 rotates, it can directly drive the rotating rod 7 to rotate synchronously, thereby adjusting the angle of the semicircular plate 5 or the preload of the torsion spring 8. Thus, the operation of the rotating rod 7 can be manually controlled. When it is necessary to fix the opening and closing angle of the semicircular plate 5, the sliding block 14 can be moved in the fixed frame 12, and then the rotating rod 7 can be rotated to the target angle by the hexagonal column 11. Then, the block 14 can be pushed into the corresponding slot 16 to lock it, which facilitates fixing the opening and closing angle of the semicircular plate 5 and makes it convenient for operators to clean the material adsorbed on the surface of the semicircular plate 5. The cooperation between the guide block 15 and the guide groove 13 ensures that the block 14 slides smoothly and avoids accidental disengagement.

[0024] As a further technical solution of this embodiment, the protective ring frame 4 is equipped with an inclined annular guide frame 17. The inclined annular guide frame 17 can guide the falling materials such as rice husks, so that the materials can flow more smoothly down the inclined surface, reduce the jamming and accumulation of materials during the falling process, and further improve the efficiency and stability of material feeding.

[0025] As a further technical solution of this embodiment, a through groove 9 adapted to the rotating rod 7 is provided on one side of the fixing block 18. The rotating rod 7 is rotatably connected in the through groove 9. The fixing block 18 is set on the outside of the semicircular plate 5. The through groove 9 on one side of the fixing block 18 is rotatably connected to the rotating rod 7. The fixing block 18 can rotate freely around the axis of the rotating rod 7, so that the opening and closing action of the semicircular plate 5 is directly realized by the rotating rod 7, ensuring the stability and accuracy of the rotation, and avoiding jamming or misalignment caused by loose connection.

[0026] The working principle of this utility model: 1) Under normal feeding conditions, materials such as rice husks are conveyed downward from the chute body 1. When the material reaches the protective ring frame 4, the inclined ring guide frame 17 guides the falling rice husks and other materials, allowing the material to flow more smoothly downward along the inclined surface. This causes the material to generate a downward impact force on the internal semi-circular plate 5. At the same time, the semi-circular plate 5 is subjected to the weight or impact force of the material, allowing the fixed block 18 to rotate freely around the axis of the rotating rod 7. The opening and closing action of the semi-circular plate 5 is directly achieved by the rotating rod 7. At this time, the torsion spring 8 is twisted and stores elastic potential energy, which overcomes the elastic force of the torsion spring 8, causing the two semi-circular plates 5 to open to both sides, forming a feeding channel. The material can then pass smoothly through the protective ring frame 4 to complete the feeding. 2) When the material conveying is interrupted or the flow rate decreases, the impact force of the material on the semi-circular plate 5 weakens or disappears. The elastic force of the torsion spring 8 will drive the fixed block 18 to reset, causing the semi-circular plate 5 to rotate in the opposite direction, and finally causing the two semi-circular plates 5 to close again, automatically blocking the feeding channel. This process can effectively prevent external debris from entering the chute body 1, or prevent steam and hot air in the equipment below from flowing back up to the chute body 1, thus protecting the equipment and maintaining the stability of the material conveying environment. 3) If manual control or adjustment of the feeding state is required, it can be achieved by operating the auxiliary part 20 on the outside of the protective ring frame 4: the auxiliary part 20 cooperates with the rotating rod 7 to directly or indirectly change the rotation angle of the semi-circular plate 5, thereby further improving the feeding efficiency.

[0027] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the principles and essence of the present utility model should fall within the protection scope defined by the claims of the present utility model.
