Description

Technical Field

[0001] This utility model relates to the field of liquor production technology, specifically to a raw material crushing device for liquor production. Background Technology

[0002] The basic principle of raw material crushing equipment is to break raw materials into smaller particles through mechanical force or impact. These devices typically use rotating blades, hammers, or drums to crush the raw materials under high-speed rotation or impact. The crushed raw material particles are of a suitable size, which is beneficial for subsequent processes such as saccharification and fermentation.

[0003] Chinese utility model patent CN216378108U discloses a raw material crushing device for baijiu (Chinese liquor) production, relating to the field of baijiu production technology. It includes a base plate and a support column for positioning. A discharge valve is fixedly installed at the bottom of the base plate, and a fermentation tank is fixedly connected to the top of the base plate. A crushing tank is fixedly connected to the top of the fermentation tank, and a fixing cylinder is fixedly connected to one end of the crushing tank. One end of the fixing cylinder penetrates the crushing tank, and a first motor is fixedly installed at one end of the fixing cylinder. This utility model uses a water-resistant motor to drive a rotating shaft and crushing blades to rotate, further crushing the raw materials falling into the grooves and through holes, thereby improving the fermentation effect of the raw materials and increasing the yield of baijiu. By installing a differential bearing at the bottom of the rotating shaft, the rotation speed of the scraper is reduced when the crushing blades rotate at high speed, allowing the scraper to scrape the raw materials on the inner wall of the U-shaped groove and enter the fermentation tank through the bottom connection hole for fermentation, reducing the time required for transporting raw materials during fermentation.

[0004] Traditional crushing devices may rely solely on single crushing blades or hammers, lacking effective material circulation and conveying mechanisms. This leads to raw materials easily accumulating or becoming stagnant in certain areas during crushing, failing to fully contact the crushing components and thus reducing crushing efficiency. Furthermore, uneven flow within the crushing device used in baijiu production results in some raw materials receiving excessive crushing force while others are insufficiently crushed, leading to uneven particle size distribution and impacting the quality of subsequent baijiu production. Therefore, a new crushing device for baijiu production is needed to address these issues. Summary of the Invention

[0013] Compared with the prior art, this utility model provides a raw material crushing device for liquor production, which has the following beneficial effects:

[0014] 1. This raw material crushing device for liquor production comprises a first connecting shaft, a second connecting shaft, a rotating shaft, a driving gear, a driven gear, a first spiral blade, a second spiral blade, a first ramp, a second ramp, and a drive motor. The drive motor provides power, which drives the crushing blades to rotate at high speed via the rotating shaft, effectively crushing the raw materials. Simultaneously, the meshing transmission between the driving and driven gears causes the first and second connecting shafts to drive the first and second spiral blades to rotate, forming a circulating flow pattern that accelerates the crushing speed and improves the overall crushing efficiency. The first and second spiral blades rotate in opposite directions, conveying the raw materials in different directions. The drop between the first and second ramps and the vibration effect of the drive motor ensure that the raw materials are fully mixed and circulated within the chamber, guaranteeing that all parts of the raw materials are uniformly crushed, thereby improving the uniformity of the crushing process. This design avoids problems such as insufficient or excessive crushing in certain areas. The first and second spiral blades effectively transport the raw materials in a designated direction, ensuring orderly flow within the chamber and reducing accumulation and blockage during crushing. This guarantees smooth passage of the raw materials through the crushing area, improving material conveying efficiency and crushing effect. The rational design of the gear transmission and spiral blade structure allows all components to work collaboratively, fully utilizing the power of the drive motor, reducing energy loss, and improving energy utilization efficiency. This reduces the overall energy consumption of the crushing device and saves energy costs. The drive motor is easy to start and stop, and its speed can be easily adjusted via the controller to adapt to the crushing needs of different raw materials. Furthermore, the device's structure considers ease of maintenance; for example, a maintenance cover on the top of the transmission box facilitates inspection and maintenance of internal gears and other components, extending the equipment's service life.

[0020] Please see Figure 1-3 This utility model discloses a raw material crushing device for liquor production, including a raw material crusher housing 8, a first connecting shaft 19, and a second connecting shaft 13. A mounting frame 1 is fixedly connected to the bottom of the raw material crusher housing 8. A triangular bracket 3 is fixedly installed at the middle left side of the mounting frame 1.

A bearing seat 16 is provided at the end of the rotating shaft 17 away from the drive motor 6. A crushing blade 15 is fixedly installed at the middle left side of the raw material crusher housing 8. The transmission box 2 and the inner bottom wall of the raw material crusher box 8 are provided with a first ramp 20 near the left side; the inner bottom wall of the raw material crusher box 8 is provided with a second ramp 14 near the right side; the top of the raw material crusher box 8 is provided with a feeding end 10 near the right side, and a sealing cover 9 is provided on the feeding end 10; the outer surface of the first connecting shaft 19 is provided with a first spiral blade 18, and the outer surface of the second connecting shaft 13 is provided with a second spiral blade 1; a driven gear 22 is fixedly connected to the outer surface of the first connecting shaft 19 and the second connecting shaft 13 near the left side; a second bearing seat 16 is provided on both the left and right ends of the first connecting shaft 19 and the second connecting shaft 13. In use, when the first spiral blade 18 rotates, it drives the liquor raw material to move to the left, and when the second spiral blade 12 rotates, it drives the material to move to the right.

[0021] Specifically, the driving gear 21 and the two driven gears 22 are all located inside the transmission box 2, and the driving gear 21 meshes with the two driven gears 22.

[0022] Specifically, the left sides of the first connecting shaft 19 and the second connecting shaft 13 respectively penetrate the left side wall of the raw material crusher housing 8 near the front and rear ends and extend into the transmission box 2 and are connected to the inside of the transmission box 2. The left side wall of the transmission box 2 near the front and rear ends is fixedly connected to the left side of the second bearing seat 16 near the left side of the first connecting shaft 19 and the second connecting shaft 13. The right side wall of the raw material crusher housing 8 near the front and rear ends is fixedly connected to the right side of the second bearing seat 16 on the right side of the first connecting shaft 19 and the second connecting shaft 13. Sealing rings are provided at the connection points of the first connecting shaft 19 and the second connecting shaft 13 with the raw material crusher housing 8.

[0023] Specifically, the interior of the rotating shaft 17 penetrates the interior left side wall of the raw material crusher housing 8 and the interior left side wall of the transmission box 2, extends out of the left side of the transmission box 2 and is connected to the drive motor 6; a sealing ring is provided at the connection between the rotating shaft 17 and the raw material crusher housing 8, and the connection between the rotating shaft 17 and the raw material crusher housing 8 is provided by a ball bearing, and the end of the bearing seat 16 away from the rotating shaft 17 is fixedly connected to the interior right side wall of the raw material crusher housing 8 near the center.

[0024] Specifically, the first ramp 20 is inclined near the rear end and at an angle not exceeding 10 degrees, and the second ramp 14 is inclined near the front end and at an angle not exceeding 10 degrees.

[0025] Specifically, the top of the transmission box 2 is provided with a maintenance cover 7, the mounting bracket 1 is provided with a controller 11, and the top of the triangular bracket 3 is fixedly connected to the bottom of the extension plate 4.

[0026] Specifically, a discharge end is provided at the bottom middle of the raw material crusher box 8. The bottom of the discharge end penetrates through the top of the mounting frame 1 and extends out of the inner top wall of the mounting frame 1. A control valve is provided on the discharge end.

[0027] When using this raw material crusher, first, ensure the equipment is in good working order. Check that all connections are secure, the sealing cover 9 is intact, and the discharge control valve is closed. Then, open the sealing cover 9 and slowly add the precisely proportioned raw materials to be crushed into the crusher housing 8 through the feeding end 10. Note that the addition should be even and slow to avoid adding too much at once, which could lead to insufficient crushing or overloading the equipment. After adding the materials, tightly close the sealing cover 9 to ensure no material leaks out during the mixing process. Simultaneously check the sealing effect of the sealing ring to prevent dust or liquid leakage. Next, start the drive motor 6. The motor will quickly start running, and its output will drive the rotating shaft 17 to rotate. As the rotating shaft 17 rotates... The crushing blades 15 fixed on its outer surface also rotate at high speed, crushing the liquor raw materials in the mixing tank. The crushing blades 15 are reasonably set to adapt to liquor raw materials with different hardness and properties, ensuring the crushing effect. At the same time, the drive gear 21 is also driven to rotate, which in turn drives the two driven gears 22 to rotate. Utilizing the ingenious meshing of the drive gear 21 and the two driven gears 22, the two driven gears 22 exhibit opposite rotation directions when rotating. This opposite rotation characteristic causes the two driven gears 22 to rotate in two different directions, thereby driving the first connecting shaft 19 and the second connecting shaft 13 to rotate in two different directions. The rotation of shaft 9 and the second connecting shaft 13 drives the first spiral blade 18 and the second spiral blade 12 to rotate respectively. The characteristics of the first spiral blade 18 cause the raw materials to be crushed, located away from the drive motor 6, to be drawn towards the end closer to the drive motor 6. These drawn materials then smoothly flow into the left side of the bottom wall of the raw material crusher housing 8 near the rear end as they pass through the drop of the first ramp 20. The inclination angle of the first ramp 20 does not exceed 10 degrees to ensure the smooth sliding of the raw materials. Simultaneously, the second spiral blade 12 utilizes its unique spiral characteristics to draw the raw materials near the drive motor 6 towards the end away from the drive motor 6. These materials also utilize the drive motor 18 to rotate when passing through the drop of the second ramp 14. The vibration effect of motor 6 smoothly directs the raw materials into the bottom right side of the raw material crusher housing 8, near the front end. The inclination angle of the second ramp 14 also does not exceed 10 degrees to ensure the smooth sliding of the raw materials. In this way, the raw materials for liquor form an efficient circulation flow pattern within the raw material crusher housing 8: one end is drawn to the left, and then flows to the other end through the ramp drop and vibration effect; the other end is drawn to the right, and then flows back through the ramp drop and vibration effect on the other side. This circulation flow not only accelerates the crushing speed of the raw materials for liquor, but also greatly improves the uniformity of crushing, avoiding the problems of insufficient or excessive crushing in certain areas. As the stirring time progresses, the raw materials for liquor gradually become uniform and fine, achieving the expected crushing effect.During the crushing process, the crushing status of the raw materials can be observed in real time. The speed of the drive motor 6 can be adjusted via the controller 11 to adapt to the crushing requirements of different raw materials. After the expected crushing effect is achieved, the drive motor 6 can be turned off, and a period of time can be waited for the liquor raw materials in the mixing tank to settle slightly, ensuring the uniformity and stability of the raw materials. Then, the control valve at the discharge end can be opened to smoothly discharge the mixed liquor raw materials for subsequent use. When discharging, care should be taken to control the discharge speed to avoid excessive speed causing raw materials to splash or block the discharge end. After discharge, the equipment should be cleaned in time to keep it clean and hygienic, preparing it for the next use.

[0028] In summary, this raw material crushing device for liquor production comprises a first connecting shaft 19, a second connecting shaft 13, a rotating shaft 17, a driving gear 21, a driven gear 22, a first spiral blade 18, a second spiral blade 12, a first ramp 20, a second ramp 14, and a drive motor 6. The drive motor 6 provides power, which drives the crushing blades 15 to rotate at high speed via the rotating shaft 17, effectively crushing the raw materials. Simultaneously, the meshing transmission between the driving gear 21 and the driven gear 22 causes the first connecting shaft 19 and the second connecting shaft 13 to drive the first spiral blades 18 and 12 to rotate, forming a circulating flow pattern, accelerating the crushing speed of the raw materials and improving the overall crushing efficiency. The first spiral blades 18 and 12 rotate in opposite directions, conveying the raw materials in different directions. Furthermore, the drop between the first ramp 20 and the second ramp 14, along with the vibration effect of the drive motor 6, ensures that the raw materials are fully mixed and circulated within the chamber, guaranteeing uniform crushing of all parts of the raw materials. The material is evenly crushed, thus improving the uniformity of crushing and avoiding problems such as insufficient or excessive crushing in certain areas. The arrangement of the first spiral blade 18 and the second spiral blade 12 can effectively transport the raw material in a designated direction, allowing the raw material to flow orderly within the box, reducing the accumulation and blockage of raw material during the crushing process, ensuring that the raw material passes smoothly through the crushing area, and improving the material conveying efficiency and crushing effect. Through the reasonable arrangement of gear transmission and spiral blade structure, the various components work together to make full use of the power of the drive motor 6, reduce energy loss, improve energy utilization efficiency, thereby reducing the energy consumption of the entire crushing device and saving energy costs. The start and stop operation of the drive motor 6 is simple, and the speed of the motor can be easily adjusted by the controller 11 to adapt to the crushing requirements of different raw materials. At the same time, the structure of the device takes into account the convenience of maintenance. For example, the top of the transmission box 2 is equipped with a maintenance cover 7, which facilitates the inspection and maintenance of internal gears and other components, extending the service life of the equipment.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
