Description
Technical Field
[0001] This utility model belongs to the field of liquor technology, and in particular relates to a wheat grinding device for liquor koji making. Background Technology
[0002] In the wheat processing stage of baijiu (Chinese liquor) koji making, traditional grinding equipment has long faced two major challenges that severely restrict production efficiency and the stability of koji quality. The problems of "material jamming" and "uneven material supply" in the feeding stage are prominent. The storage bins of traditional equipment rely solely on the gravity of the wheat itself for falling. When there are differences in the size of the wheat grains or a small amount of impurities mixed in, it is very easy to form a "grain arch" at the discharge port. The grains bite and squeeze each other, forming a stable accumulation structure at the bottom of the bin, which leads to a sudden interruption of the raw material supply. Even if it is not completely blocked, the falling process is obviously intermittent: initially, due to the concentration of gravity, a large amount of wheat may rush in instantly, causing the grinding disc to operate under overload, so that some coarse grains are not fully crushed; then, due to the increased accumulation resistance, the feeding amount drops sharply, and the grinding disc spins idly, causing the proportion of fine powder to soar. This fluctuating feeding rhythm directly disrupts the grinding ratio of wheat grains, making it difficult to meet the requirements of the koji making process for the gradient distribution of coarse, medium and fine particles, and thus affecting the aeration and nutrient supply balance of subsequent microbial fermentation.
[0003] Existing grinding equipment lacks a continuous vibration structure similar to a shaking bucket during use. The wheat in the storage bin mainly relies on gravity to fall naturally. When the wheat grains are uneven in size or contain impurities, the grains are very likely to squeeze and bite each other, forming a stable arched accumulation at the bottom of the bin, which can lead to interruption of raw material transportation. Utility Model Content
[0004] The purpose of this utility model is to provide a wheat grinding device for making baijiu (Chinese liquor) koji. By setting up an oscillating part, it solves the problem that existing grinding devices lack a continuous vibration structure similar to a shaking barrel during use. The wheat in the storage bin mainly relies on gravity to fall naturally. When the wheat grains are uneven in size or contain impurities, the grains are very likely to squeeze and bite each other, forming a stable arched accumulation at the bottom of the bin, which leads to the interruption of raw material transportation.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a wheat grinding device for making baijiu (Chinese liquor) koji, including a support frame and a collection box fixedly connected inside the support frame. The collection box is provided with a sealing door. It also includes: a vibration part, which is installed on the support frame; and a cleaning part, which is provided on the support frame. The oscillation unit includes a transmission assembly mounted on a support frame; and a swaying assembly disposed on the transmission assembly. The transmission assembly includes a storage bin fixedly connected to the inner wall of the support frame. An annular upper grinding disc is fixedly connected to the bottom of the storage bin. A bracket is fixedly connected to the inner wall of the collection box. A motor is fixedly connected to the inner wall of the bracket. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The bottom of the annular upper grinding disc has several grinding grooves, which are distributed radially in a circumferential array. The depth of the grinding grooves is smaller than the size of wheat grains to ensure the grinding effect. The bottom of the rotating shaft is threaded. The shaking assembly includes a shaking barrel disposed in a storage hopper, with a ratchet block fixedly connected to the inner side wall of the shaking barrel, and elastic and limiting elements disposed inside the shaking barrel; wherein the ratchet blocks are distributed in a circumferential array inside the shaking barrel.
[0006] Furthermore, the elastic element includes a spring 1 disposed inside the shaking barrel, the top of the spring 1 being fixedly connected to the shaking barrel, and the bottom of the spring 1 being fixedly connected to the rotating shaft.
[0007] Furthermore, the limiting member includes a limiting rod fixedly connected to the top of the cleaning section, the limiting rod being adapted to the ratchet block; wherein the end of the limiting rod is ratchet-shaped.
[0008] Furthermore, the cleaning unit includes an adjustment assembly mounted on the transmission assembly; and an elastic assembly disposed on the adjustment assembly; wherein the elastic assembly is sleeved on the outer wall of the rotating shaft.
[0009] Furthermore, the adjustment assembly includes a lower grinding disc slidably connected to the outer wall of the rotating shaft, the top of the rotating shaft passing through the lower grinding disc, the lower half of the rotating shaft being threaded, and a hexagonal block being threadedly connected to the outer wall of the lower half of the rotating shaft; wherein, the bottom of the shaking barrel contacts the top of the lower grinding disc, and the hexagonal block is hexagonal.
[0010] Furthermore, the elastic component includes two fixing rings disposed on the outer wall of the rotating shaft, and a second spring is sleeved on the outer wall of the rotating shaft. The top and bottom of the second spring are respectively fixedly connected to the two fixing rings; wherein, the lower fixing ring is in contact with the upper surface of the hexagonal block, and the upper fixing ring is in contact with the lower surface of the lower grinding disc.
[0011] This utility model has the following beneficial effects: 1. By setting up an oscillating part, when the motor drives the rotating shaft to rotate, the shaking barrel rotates synchronously with the rotating shaft under the traction of spring one. The alternating action of the limiting rod and the ratchet continuously breaks its rotational inertia. When the limiting rod is stuck in the gap of the ratchet, the shaking barrel is forced to tilt or shift, causing spring one to twist and deform. When the limiting rod is freed from the ratchet constraint, the elastic potential energy of spring one is released instantly, driving the shaking barrel to quickly reset and generate high-frequency, small-amplitude reciprocating shaking. Through continuous vibration, the wheat in the storage bin is loosened and fluidized, avoiding local blockage caused by gravity falling naturally, and ensuring that the raw materials enter the grinding groove between the upper and lower grinding discs evenly and continuously. 2. By setting up a cleaning section, when the hexagonal block is rotated, it moves downwards in a straight line along the threaded structure of the rotating shaft, gradually releasing the pressure on the fixed ring. This allows the second spring to gradually return to its original state from compression. As the elasticity of the second spring disappears, the lower grinding disc loses its axial pressure constraint, and the distance between it and the annular upper grinding disc gradually increases as the hexagonal block continues to move downwards. This eventually forms an operating space sufficient to accommodate cleaning tools, avoiding a complicated disassembly process. It also allows residual flour and impurities to be thoroughly removed in the open space, preventing mold and contamination. At the same time, the distance adjustment process is smooth and controllable, without affecting the fitting accuracy of the grinding disc. This ensures that the equipment can quickly return to normal working condition after cleaning, balancing cleaning efficiency and equipment stability.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-6 As shown, this utility model is a wheat grinding device for making baijiu (Chinese liquor) koji, including a support frame 111 and a collection box 112 fixedly connected in the support frame 111. The collection box 112 is provided with a sealing door 113. It also includes: an oscillation part 2, which is installed on the support frame 111; and a cleaning part 3, which is provided on the support frame 111. The oscillation unit 2 includes a transmission assembly 21 and a shaking assembly 22. The transmission assembly 21 is mounted on the support frame 111, and the shaking assembly 22 is disposed on the transmission assembly 21. The transmission assembly 21 includes a storage bin 211 fixedly connected to the inner wall of the support frame 111. An annular upper grinding disc 212 is fixedly connected to the bottom of the storage bin 211. Several grinding grooves are opened at the bottom of the annular upper grinding disc 212 and are distributed radially in a circumferential array. A bracket 213 is fixedly connected to the inner wall of the collection box 112. A motor 214 is fixedly connected to the inner wall of the bracket 213. The output shaft of the motor 214 is fixedly connected to a rotating shaft 215 through a coupling. The shaking assembly 22 includes a shaking barrel 221 disposed in the storage bin 211. A ratchet block 222 is fixedly connected to the inner side wall of the shaking barrel 221. An elastic element and a limiting element are disposed inside the shaking barrel 221. The ratchet blocks 222 are distributed in a circumferential array inside the shaking barrel 221. The elastic element includes a spring 223 disposed inside the shaking barrel 221. The top of the spring 223 is fixedly connected to the shaking barrel 221, and the bottom of the spring 223 is fixedly connected to the rotating shaft 215. The limiting component includes a limiting rod 224 fixedly connected to the top of the lower grinding disc 311. The limiting rod 224 is adapted to the ratchet block 222. The end of the limiting rod 224 is ratchet-shaped. By setting the oscillation part 2, the wheat in the storage bin 211 is loosened and fluidized by continuous vibration, avoiding local blockage caused by gravity falling naturally, and ensuring that the raw material enters the grinding groove between the upper and lower grinding discs evenly and continuously.
[0018] The cleaning unit 3 includes an adjustment component 31 and an elastic component 32. The adjustment component 31 is mounted on the transmission component 21, and the elastic component 32 is disposed on the adjustment component 31. The elastic component 32 is sleeved on the outer wall of the rotating shaft 215. The adjusting component 31 includes a lower grinding disc 311 slidably connected to the outer wall of the rotating shaft 215 (the lower grinding disc 311 and the rotating shaft 215 can only slide up and down, not rotate; the lower grinding disc 311 will also rotate when the rotating shaft 215 rotates). The upper surface of the lower grinding disc 311 has several grinding grooves arranged in a radial array. The length of the grinding grooves of the lower grinding disc 311 is greater than the length of the grinding grooves of the annular upper grinding disc 212, which facilitates the entry of wheat into the grinding grooves between the upper and lower grinding discs. The top of the rotating shaft 215 passes through the lower grinding disc 311. The lower half of the rotating shaft 215 is threaded, and a hexagonal block 312 is threaded to the outer wall of the lower half of the rotating shaft 215. The bottom of the shaking barrel 221 contacts the middle of the top of the lower grinding disc 311, and the hexagonal block 312 is hexagonal. The elastic component 32 includes two fixing rings 321 disposed on the outer wall of the rotating shaft 215 (the two fixing rings are simply sleeved on the outer wall of the rotating shaft 215 and can slide freely up and down), and a second spring 322 is sleeved on the outer wall of the rotating shaft 215. The top and bottom of the second spring 322 are fixedly connected to the two fixing rings 321 respectively. The lower fixing ring 321 is in contact with the upper surface of the hexagonal block 312, and the upper fixing ring 321 is in contact with the lower surface of the lower grinding disc 311.
[0019] By setting up cleaning section 3, the complicated disassembly process is avoided, and residual flour and impurities can be thoroughly removed in an open space to prevent mold and contamination. At the same time, the spacing adjustment process is stable and controllable and will not affect the fitting accuracy of the grinding disc, ensuring that the equipment can quickly return to normal working condition after cleaning, thus balancing cleaning efficiency and equipment stability.
[0020] A specific application of this embodiment is as follows: In use, the wheat to be ground is first placed in the storage bin 211, and then the motor 214 on the bracket 213 can be started. At this time, the motor 214 will drive the rotating shaft 215 to rotate. When the rotating shaft 215 rotates, it will drive the shaking barrel 221 to rotate through the spring 223. With continuous rotation, the shaking barrel 221 will be restricted by the limiting rod 224 and the ratchet block 222 to tilt or undergo a certain displacement. At this time, the spring 223 will twist. After the limiting rod 224 passes through one of the ratchet blocks 222, the spring 223 will reset. With the reset of the spring 223, the shaking barrel 221 will shake. At this time, the shaking barrel 221 will vibrate the wheat in the storage bin 211 (the vibration amplitude is not very large, so it can also prevent the wheat from entering the shaking barrel). Then the vibrated wheat will go deeper into the grinding groove of the downward grinding disc 311 and the annular upper grinding disc 212. As the rotating shaft 215 rotates, the lower grinding disc 311 also rotates. The grinding grooves on the lower grinding disc 311, together with those on the annular upper grinding disc 212, grind the wheat. The depth of the grinding grooves is less than the size of the wheat particles to ensure effective grinding. The ground wheat slides through the edge gap between the annular upper grinding disc 212 and the lower grinding disc 311 and falls into the collection box 112. When the ground wheat needs to be removed, the sealing door 113 can be opened. Shaking the rotating bucket 221 allows the wheat to quickly enter the grinding grooves. After use, both the lower grinding disc 311 and the annular upper grinding disc 212 need to be cleaned. During cleaning, rotating the hexagonal block 312 causes it to move downwards via the threads on the rotating shaft 215. As it moves downwards, it stops pressing on the retaining ring 321 and the second spring 322. The pressure exerted by the retaining ring 321 and the second spring 322 on the lower grinding disc 311 gradually decreases and disappears. After rotating the hexagonal block 312 to the bottom end of the rotating shaft 215, the two retaining rings 321 and the second spring 322 fall downwards. Due to gravity, the lower grinding disc 311 moves downwards along the rotating shaft 215, increasing the distance between the lower grinding disc 311 and the annular upper grinding disc 212, thus achieving a sufficient cleaning distance and facilitating cleaning.
