Technical Field
[0001] This utility model relates to the field of liquor brewing technology, and in particular to a raw material crushing device for brewing liquor. Background Technology
[0002] Baijiu is a distilled spirit, colorless or slightly yellow and transparent, with a pure and fragrant aroma, a smooth and sweet taste, and a relatively high alcohol content. After aging, it develops a complex aroma primarily composed of esters. It is a type of spirit made from starchy and sugary raw materials using koji (fermentation starter) and yeast as saccharification and fermentation agents, through processes of cooking, saccharification, fermentation, distillation, aging, and blending. In the baijiu brewing process, the crushing of raw materials is a crucial step, directly affecting the effectiveness of subsequent fermentation and distillation processes, and consequently, the quality and flavor of the baijiu.
[0003] Existing pulverizing equipment produces raw materials for baijiu (Chinese liquor) that exhibit significant volume heterogeneity and large particle size differences. It lacks the function of sieving the pulverized raw materials, failing to guarantee uniform volume. This uneven volume leads to inconsistent fermentation times, further affecting the generation, transformation, and accumulation of flavor compounds during baijiu brewing, ultimately reducing the overall quality of the baijiu and diminishing the equipment's practicality.
[0004] Therefore, this utility model proposes a raw material crushing device for brewing baijiu (Chinese liquor) to solve the problems existing in the prior art. Utility Model Content
[0005] To address the aforementioned problems, this utility model proposes a raw material crushing device for brewing baijiu (Chinese liquor) to solve the problem that the existing technology does not have the function of screening the crushed baijiu brewing raw materials, which cannot guarantee the uniformity of the volume of the crushed baijiu brewing raw materials, resulting in uneven volume of the crushed baijiu brewing raw materials and inconsistent fermentation time of the baijiu brewing raw materials.
[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a raw material crushing device for brewing liquor, including a crushing box, two crushing blades rotatably connected inside the crushing box, the front end of the crushing blades penetrating the inside of the crushing box and fixedly installed with a first gear, the two first gears being meshed with each other, a support block fixedly installed near the bottom of the front side of the crushing box, a drive motor for driving the adjacent crushing blades to rotate fixedly installed on the top of the support block, a feed funnel fixedly installed on the top of the crushing box, a screening box fixedly installed at the bottom of the drive motor, a discharge port fixedly installed on the left side of the screening box near the top, and a screening component provided inside the screening box for screening the crushed raw materials.
[0007] Further improvements include: a crushing blade adapted to the crushing blade is fixedly installed on the inner side wall of the crushing box; the crushing box is connected to the feeding funnel and the screening box; and support legs are fixedly installed at the bottom of the crushing box near the four corners.
[0008] A further improvement is that a guide frame is fixedly installed on the bottom inner side of the screening box near the left and right sides, and a discharge pipe is fixedly installed on the front side of the screening box between the two guide frames.
[0009] A further improvement is that the screening component includes a screening plate, a connecting block is fixedly installed at the bottom of the screening plate near the front and rear sides, a rotating rod is provided through the inner side of the screening box and located at the bottom of the screening plate and is rotatably connected to it, a cam is rotatably connected to the surface of the rotating rod and located at the bottom of the connecting block, lifting blocks are fixedly installed at the front and rear sides of the screening plate, and a lifting groove is provided on the inner side wall of the screening box for the lifting blocks to slide up and down.
[0010] A further improvement is that a first grooved wheel is fixedly installed on the surface of the rotating rod near the front end, and a second grooved wheel is fixedly installed on the surface of the crushing blade on the right side near the front end. The surfaces of the first and second grooved wheels are fitted with belts and are connected by belt drive.
[0011] A further improvement is that: an auger blade is rotatably connected to the inner side of the screening box near the bottom center; a second gear is rotatably connected to the rear side of the screening box; a third gear that meshes with the second gear is fixedly installed at the rear end of the rotating rod; and the front end of the second gear is fixedly connected to the rear end of the auger blade.
[0012] The beneficial effects of this utility model are as follows: 1. The crushing blades are driven by a grooved belt to drive the screening components. The cam drives the screening plate to vibrate up and down, which can efficiently separate raw materials with uneven volume after crushing. Raw materials with excessively large particle size can be discharged through the discharge port and can be put back into crushing. This completely solves the defect of traditional devices that do not have screening function and effectively ensures the uniformity of the volume of raw materials that pass through screening.
[0013] 2. The rotating rod is driven to rotate by the second grooved wheel, belt, and first grooved wheel, which provides power to the screening component. There is no need to add an additional screening drive device, which simplifies the structure of the device and reduces energy consumption.
[0014] 3. The rotating rod drives the auger blades to rotate through the third and second gears. Together with the guide frame at the bottom of the screening box, it can gather qualified raw materials and automatically push them forward. Finally, the materials are discharged through the discharge pipe. Compared with the traditional manual cleaning or natural discharge method, it greatly improves the efficiency of raw material transportation and avoids the interruption of the brewing process caused by the accumulation and blockage of raw materials.

Detailed Implementation
[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0021] according to Figure 1-4 As shown, this embodiment proposes a solution: a raw material crushing device for brewing baijiu (Chinese liquor), including a crushing box 1, two crushing blades 2 rotatably connected inside the crushing box 1, the front end of the crushing blades 2 penetrating the inside of the crushing box 1 and fixedly installed with a first gear 3, the two first gears 3 being meshed with each other, a support block fixedly installed near the bottom of the front side of the crushing box 1, a drive motor 4 for driving the adjacent crushing blades 2 to rotate fixedly installed on the top of the support block, a feed funnel 5 fixedly installed on the top of the crushing box 1, a screening box 6 fixedly installed at the bottom of the drive motor 4, a discharge port fixedly installed on the left side of the screening box 6 near the top, and a screening component provided inside the screening box 6 for screening the crushed raw materials.
[0022] In this embodiment, the drive motor 4 starts and drives the adjacent crushing blades 2 to rotate. Since the first gear 3, which passes through the front end of the two crushing blades 2 and is fixed to the crushing box 1, meshes with each other, when one crushing blade 2 rotates, it will drive the other crushing blade 2 to rotate synchronously in the opposite direction through gear meshing. At this time, the raw materials for brewing liquor are put into the feed funnel 5 at the top of the crushing box 1. After the raw materials enter the crushing box 1, they will be crushed by the two crushing blades 2 rotating in opposite directions. The crushed raw materials will fall directly into the screening box 6 below. Through the action of the screening component, the raw materials with uneven volume after crushing can be efficiently separated, which completely solves the defect of traditional devices that do not have screening function and effectively ensures the uniformity of the volume of the raw materials that pass through the screening. The unqualified crushed raw materials are discharged through the discharge port and fall into the inner side of the pre-prepared storage cylinder, and are put back into the inner side of the feed funnel 5 for repeated crushing processing.
[0023] The inner wall of the crushing box 1 is fixedly installed with crushing blades 7 that are compatible with the crushing blades 2. The crushing box 1 is connected to the feeding funnel 5 and the screening box 6. Support legs 8 are fixedly installed at the bottom of the crushing box 1 near the four corners. Through the gear meshing and reverse rotation design of the double crushing blades 2, in conjunction with the fixed crushing blades 7, the raw materials can be crushed more comprehensively and thoroughly, greatly reducing the situation of incomplete crushing of raw materials.
[0024] A guide frame 9 is fixedly installed on the bottom inner side of the screening box 6 near the left and right sides. A discharge pipe 10 is fixedly installed on the front side of the screening box 6 between the two guide frames 9. Through the action of the guide frame 9, the crushed raw material screened by the screening component is guided and discharged through the discharge pipe 10.
[0025] The screening assembly includes a screening plate 11. Connecting blocks are fixedly installed on the bottom of the screening plate 11 near the front and rear sides. A rotating rod 12 is installed through the screening box 6 and rotatably connected to the bottom of the screening plate 11. A cam 13 is rotatably connected to the surface of the rotating rod 12 and the bottom of the connecting blocks. Lifting blocks 14 are fixedly installed on the front and rear sides of the screening plate 11. A lifting groove is opened on the inner wall of the screening box 6 for the lifting blocks 14 to slide up and down. During the rotation of the rotating rod 12, the two cams 13 are driven to rotate. The protruding part of the cam 13 will periodically push up the connecting blocks. Through the action of the connecting blocks, the screening plate 11 moves up and down. Under the vibration of the screening plate 11, the raw materials with the required particle size will fall through the sieve holes of the screening plate 11, while the raw materials with the excessively large particle size will remain on the screening plate 11 and finally be discharged from the discharge port on the left side of the screening box 6. This avoids the problem of inconsistent fermentation time caused by the large difference in the size of the raw material particles, thereby ensuring the stability of the generation, transformation and accumulation of flavor substances during the brewing process of baijiu and significantly improving the overall brewing quality of baijiu.
[0026] A first grooved wheel 15 is fixedly installed on the surface of the rotating rod 12 near the front end, and a second grooved wheel 16 is fixedly installed on the surface of the right crushing blade 2 near the front end. The surfaces of the first grooved wheel 15 and the second grooved wheel 16 are fitted with belts and are connected by belt drive. During the rotation of the crushing blade 2, the second grooved wheel 16 fixed at the front end of the right crushing blade 2 will drive the first grooved wheel 15 at the front end of the rotating rod 12 in the screening box 6 to rotate synchronously through the belt, thereby causing the rotating rod 12 to rotate accordingly. There is no need to add an additional screening drive device, which simplifies the structure of the device and reduces energy consumption.
[0027] A screw conveyor blade 17 is rotatably connected to the inner side of the screening box 6 near the bottom center. A second gear 18 is rotatably connected to the rear side of the screening box 6. A third gear 19, which meshes with the second gear 18, is fixedly installed at the rear end of the rotating rod 12. The front end of the second gear 18 is fixedly connected to the rear end of the screw conveyor blade 17. When the rotating rod 12 rotates, the second gear 18 rotates synchronously through the meshing of the second gear 18 and the third gear 19. The screw conveyor blade 17 will rotate with the second gear 18. Under the guidance of the guide frame 9, the material is gathered at the screw conveyor blade 17, pushing the gathered qualified raw materials forward and finally discharging them through the discharge pipe 10. This facilitates subsequent collection and fermentation. Compared with the traditional manual cleaning or natural discharge method, this greatly improves the raw material conveying efficiency.
[0028] The above embodiment discloses a raw material crushing device for brewing baijiu (Chinese liquor). When the drive motor 4 starts, it drives adjacent crushing blades 2 to rotate. Since the first gear 3, which passes through and is fixed to the front end of the two crushing blades 2, meshes with each other, when one crushing blade 2 rotates, it drives the other crushing blade 2 to rotate synchronously in the opposite direction through gear meshing. At this time, the baijiu brewing raw materials are fed into the feed funnel 5 at the top of the crushing box 1. After entering the crushing box 1, the raw materials are crushed by the two counter-rotating crushing blades 2. The crushed raw materials fall directly into the screening box 6 below. During the rotation of the crushing blades 2, the second grooved wheel 16 fixed to the front end of the right crushing blade 2 drives the first grooved wheel 15 at the front end of the rotating rod 12 inside the screening box 6 to rotate synchronously via a belt. This causes the rotating rod 12 to rotate, driving the two cams 13 to rotate. The protruding part of the cam 13 rotates around... The connecting block is periodically lifted, which drives the screening plate 11 to move up and down. Under the vibration of the screening plate 11, raw materials with the required particle size will fall through the sieve holes of the screening plate 11, while raw materials with excessively large particle size will remain on the screening plate 11 and eventually be discharged from the discharge port on the left side of the screening box 6. This avoids the problem of inconsistent fermentation time caused by large differences in the size of raw material particles, thereby ensuring the stability of the generation, transformation and accumulation of flavor substances during the brewing process of baijiu and significantly improving the overall brewing quality of baijiu. Through the meshing of the second gear 18 and the third gear 19, the auger blade 17 will rotate with the second gear 18. Under the guidance of the guide frame 9, the raw materials will converge at the auger blade 17, pushing the qualified raw materials forward and finally discharging them through the discharge pipe 10 for subsequent collection and fermentation. Compared with the traditional manual cleaning or natural dropping method, this greatly improves the raw material conveying efficiency.
