[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0026] Example 1
[0027] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a preparation device for fermentation of brewing raw materials, including a frame 1, a body 2, a feed hopper 3 and a discharge port 4. The body 2 is fixedly connected to the upper end of the frame 1, the feed hopper 3 is fixedly connected to the upper end of the body 2 and communicates with the body 2, the discharge port 4 is fixedly connected to the lower end of the body 2 and communicates with the body 2, and a cleansing device 5 is provided directly below the discharge port 4.
[0028] The impurity removal device 5 includes a screening mechanism 6 and a vibration mechanism 7. The screening mechanism 6 is located below the discharge port 4 and is fixedly connected to the upper end of the frame 1. The vibration mechanism 7 is located below the screening mechanism 6 and is fixedly connected to the screening mechanism 6.
[0029] Specifically, by setting up the impurity removal device 5, the crushed grain can be screened to separate out larger particles of impurities that are not fully crushed. At the same time, the vibration mechanism 7 assists in cleaning the screen holes 64 to prevent clogging, thereby improving the purity and crushing uniformity of the brewing raw materials and providing high-quality raw materials for subsequent fermentation processes.
[0030] Furthermore, the grain is poured into the feed hopper 3 and enters the machine body 2 for crushing. Then it is discharged through the discharge port 4. When the crushed grain is discharged from the discharge port 4, the impurity removal device 5 works. The crushed grain is discharged from the discharge port 4 into the screening mechanism 6 directly below for screening. The screening mechanism 6 screens out some of the larger grains that are not fully crushed and separates them from the normal and compliant grains. At the same time, the vibration mechanism 7 assists the screening mechanism 6 in screening and vibrates and cleans the screen holes 64 of the screening mechanism 6 to prevent clogging.
[0031] Example 2
[0032] The second embodiment of this utility model provides a preparation device for fermentation of brewing raw materials. The screening mechanism 6 includes fixed rods 61, springs 62, a screen plate 63, screen holes 64, and vibrators 65. There are four fixed rods 61, which are fixedly connected to the four corners of the bottom of the upper end of the frame 1. There are four springs 62, which are fixedly connected to the lower ends of the four fixed rods 61. The screen plate 63 is located directly below the discharge port 4, and the front and rear ends of the left and right sides are fixedly connected to the lower ends of the four springs 62 respectively. There are several screen holes 64, which are opened at the lower end of the screen plate 63. There are two vibrators 65, which are fixedly connected to the left and right sides of the screen plate 63 respectively.
[0033] The sieve plate 63 is tilted downwards on the front side, and the overall tilt is lower in the front and higher in the back.
[0034] Specifically, by setting up a screening mechanism 6, the vibrator 65 drives the screen plate 63 to vibrate elastically and the inclined plate design enables the crushed grain to achieve particle size separation during the sliding process, effectively screening out raw material particles that meet the fermentation requirements and improving the uniformity and purity of brewing raw materials.
[0035] Furthermore, the crushed grain is discharged from the discharge port 4 and falls into the screen plate 63. At the same time, the vibrator 65 is started, which drives the screen plate 63 to vibrate. The screen plate 63 forms elastic vibration through the structure of four springs 62 connected to the fixed rod 61, causing the grain on the screen plate 63 to vibrate and slide towards the front of the screen plate 63 on the inclined plate surface. During this process, the grain that meets the particle size requirements falls through the screen hole 64, while larger particles that are not fully crushed slide down the front of the screen plate 63 and are discharged.
[0036] Example 3
[0037] The third embodiment of this utility model provides a preparation device for fermentation of brewing raw materials. The vibration mechanism includes a beating component and a linkage component. There are two beating components, which are respectively arranged on the left and right sides below the sieve plate. The linkage component is arranged on the lower front end of the two beating components and is fixedly connected to the sieve plate.
[0038] The tapping assembly includes a rotating seat, a striking plate, and a tension spring. The rotating seat is fixedly connected to the front end of the lower surface of the sieve plate. The front end of the striking plate is sleeved on the surface of the rotating seat and rotatably connected to the rotating seat. The tension spring is fixedly connected to the rear end of the upper surface of the striking plate, and its upper end is fixedly connected to the lower surface of the sieve plate.
[0039] A number of rubber balls are uniformly fixedly connected to the upper surface of the striking plate, and the upper side of the rubber balls is in contact with the lower surface of the sieve plate.
[0040] The linkage assembly includes a motor, a rotating rod, extrusion wheels, and a support base. The motor is fixedly connected to the right side of the front end of the lower surface of the screen plate. The rotating rod is fixedly connected to the output end of the motor. There are two extrusion wheels, which are respectively sleeved on the left and right end surfaces of the rotating rod and fixedly connected to the rotating rod. The positions of the two extrusion wheels and the front ends of the two impact plates correspond to and are adapted to each other. The support base is sleeved on the left end surface of the rotating rod and rotatably connected to the rotating rod, and its upper end is fixedly connected to the lower surface of the screen plate.
[0041] Specifically, by setting up the vibration mechanism 7, the linkage component 72 drives the impact plate 712 to periodically impact the screen plate 63, which can shake off the particulate impurities blocking the screen holes 64. At the same time, the rubber ball 8 provides elastic buffering to prevent damage to the screen plate 63 and reduce noise, ensuring that the screening process is efficient and continuous and the equipment operates stably.
[0042] Furthermore, during auxiliary screening, the motor 721 in the linkage assembly 72 drives the rotating rod 722 to rotate. The extrusion rollers 723 at both ends of the rotating rod 722 periodically extrude the front end of the impact plate 712, causing the impact plate 712 to rotate downward around the rotating seat 711 when it is extruded. At the same time, the tension spring 713 is stretched. When the extrusion rollers 723 disengage from the impact plate 712, the tension spring 713 resets and drives the impact plate 712 to quickly reset. The rubber ball 8 on the upper surface of the impact plate 712 strikes the lower surface of the screen plate 63, and the vibration force is transmitted to the screen hole 64, shaking off the blocked particle impurities and ensuring that the screening efficiency remains stable.
[0043] Meanwhile, the rubber ball 8 can prevent the impact plate 712 from damaging the screen plate 63 when it hits, and the buffering effect generated by its elastic deformation can reduce vibration noise and improve the stability and comfort of the equipment operation.
[0044] Working principle:
[0045] The crushed grain is discharged from the discharge port 4 and falls into the screen plate 63. At the same time, the vibrator 65 is started, which drives the screen plate 63 to vibrate. The screen plate 63 forms elastic vibration through the structure of four springs 62 connected to the fixed rod 61, causing the grain on the screen plate 63 to vibrate and slide towards the front of the screen plate 63 on the inclined plate surface. During this process, the grain that meets the particle size requirements falls through the screen holes 64, while larger particles that are not fully crushed slide down the front of the screen plate 63 and are discharged. During auxiliary screening, the motor 721 in the linkage component 72 is started to drive the rotating rod 722 to rotate. The extrusion rollers 723 at both ends of the rotating rod 722 will periodically squeeze. The front end of the impact plate 712 is pressed, causing the impact plate 712 to rotate downward around the rotating seat 711 when it is squeezed. At the same time, the tension spring 713 is stretched. When the extrusion wheel 723 disengages from the impact plate 712, the tension spring 713 resets, causing the impact plate 712 to quickly reset. The rubber ball 8 on the upper surface of the impact plate 712 strikes the lower surface of the screen plate 63, and the vibration force is transmitted to the screen hole 64, shaking off the blocked particles and impurities, ensuring that the screening efficiency remains stable. At the same time, the rubber ball 8 can prevent the impact plate 712 from damaging the screen plate 63 when it strikes, and the buffering effect generated by its elastic deformation can reduce vibration noise and improve the stability and comfort of the equipment operation.
[0046] In summary, by using the combined components of frame 1, machine body 2, feed hopper 3, discharge port 4, impurity removal device 5, screening mechanism 6, fixed rod 61, spring 62, screen plate 63, screen hole 64, vibrator 65, impact mechanism, striking assembly 71, rotating seat 711, striking plate 712, tension spring 713, linkage assembly 72, motor 721, rotating rod 722, extrusion wheel 723, support seat 724, and rubber ball 8, preliminary impurity removal and screening of the crushed grain is achieved, while simultaneously cleaning impurities clogging the screen holes, thus improving the purity of the raw materials and the uniformity of crushing.
