[0002] In the corn deep processing industry, crushing equipment plays a crucial role. It not only improves the efficiency of corn processing but also enhances the texture, taste, and nutritional content of the final product, meeting the diverse needs of different consumer groups.

[0003] Existing corn processing and crushing equipment often faces the problem of filter screen clogging when filtering crushed materials. Once the filter screen is clogged, the material cannot be discharged smoothly, thus hindering the normal operation of the crushing process and resulting in unsatisfactory crushing effect. The uniformity and fineness of the material are affected. In addition, screen clogging also has a negative effect on production efficiency. Because the material cannot be discharged in time, the crushing equipment has to be stopped frequently for cleaning, which not only increases the burden on operators, but also greatly reduces the production efficiency of the equipment. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a crushing device for corn processing, which overcomes the defects in the prior art, has good crushing and screening effect, and high production efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0010] Preferably, the screen is connected to the top of the filter box via a slot, and the screen mesh size is 1.18–1.28 mm. The screen mesh can be adjusted according to the fineness required by the product to meet the requirements of products with different fineness.

[0011] Preferably, the two ends of the vibration spring are fixedly connected to the upper fixed column and the lower fixed column, respectively.

[0012] Preferably, the double-roller crushing mechanism includes two identical rollers rotating in opposite directions. Several uniformly arranged crushing blades are fixedly connected to the surface of each roller, and the crushing blades on the two rollers are staggered. Both ends of the rollers are connected to bushings set on the side wall of the crushing chamber, and one end of each roller is also connected to a drive motor set outside the side wall of the crushing chamber.

[0013] Furthermore, the drive motor is mounted on the frame, which is fixedly connected to the bottom of the side wall of the crushing chamber.

[0014] Furthermore, the shredder is a cube with a length of 10mm, a width of 10mm, and a thickness of 10mm. The distance between two shredders on the same roller is 14mm, the shredders on the two rollers are arranged in an alternating pattern, and the distance between the surfaces of the two rollers is 12mm.

[0015] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] This invention utilizes high-speed rotating double rollers and correspondingly staggered crushing blades on the rollers to efficiently crush corn to achieve the desired degree of breakage. This crushing method combines shearing and impact, ensuring thorough crushing of the corn and improving the crushing effect. The vibration mechanism allows the filter box to vibrate during material discharge, effectively preventing clogging during screening and improving filtration efficiency. Simultaneously, vibration helps the material distribute more evenly within the filter box, further enhancing screening quality. Because clogging is effectively prevented, the frequency of downtime for cleaning is reduced, thereby increasing production efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1:

[0025] like Figures 1 to 5 As shown, a corn processing crushing device includes a crushing box 1. The top of the crushing box 1 has a feed inlet (not shown) and the bottom has a discharge outlet (not shown). The discharge outlet is connected to a filter box 3 via a slot 2. The top of the filter box 3 has a screen (not shown) and the bottom has a vibration mechanism (not shown). The vibration mechanism includes a vibration motor 4 located at the center of the bottom of the filter box 3, several upper fixed columns 5 evenly arranged at the bottom edge of the filter box 3, a base 6 corresponding to the bottom of the filter box 3, several lower fixed columns 7 corresponding to the upper fixed columns 5 on the base 6, and a vibration spring 8 connecting the corresponding upper fixed columns 5 and lower fixed columns 7. A double roller crushing mechanism (not shown) penetrating the inside and outside of the crushing box 1 is provided in the middle of the crushing box 1.

[0026] The crushing box 1 has support columns 9 at the bottom of its four corners, a feed funnel 10 at the feed inlet of the crushing box 1, a coarse material outlet 11 at the lower part of the side wall on one side of the crushing box 1, and a hinged door panel (not shown) at the coarse material outlet.

[0027] A fine material outlet 12 is provided on the lower part of the side wall of one side of the filter box 3.

[0028] The double-roller crushing mechanism includes two identical rollers 13 that rotate in opposite directions. Several uniformly arranged crushing blades 14 are fixedly connected to the surface of each roller 13, and the crushing blades 14 on the two rollers 13 are staggered. Both ends of the rollers 13 are connected to bushings 15 set on the side wall of the crushing box 1, and one end of each roller 13 is also connected to a drive motor 16 set outside the side wall of the crushing box 1. The drive motor 16 is set on a frame 17, and the frame 17 is fixedly connected to the bottom of the side wall of the crushing box 1.

[0029] In actual production, firstly, the drive motor 16 and the vibration motor 4 are turned on, and the corn kernels to be crushed are fed into the crushing box 1 through the feed funnel 10. The drive motor 16 drives the two rollers 13 to rotate in opposite directions, driving the crushing blades 14 to crush the corn kernels. Due to the shearing, impact and other crushing actions generated by the rollers 13 and the crushing blades 14, the corn kernels are refined. The crushed material enters the filter box 3 through the discharge port. The filter screen in the filter box 3 screens the material. The fine material passes through the filter screen and is discharged from the fine material outlet 12 for further processing or collection. The coarse material is retained in the filter box 3 and discharged when needed by opening the coarse material outlet 11. During the filtration process, the vibration motor 4 generates vibration force to drive the filter box 3 to vibrate. Vibration helps to reduce the blockage caused during screening, improves screening efficiency, and ensures that the fine material can be discharged smoothly. After completing one crushing task, the drive motor 16 and the vibration motor 4 are turned off to stop the crushing operation. The coarse material outlet 11 is opened as needed to clean the coarse material in the filter box 3.

[0030] In summary, the vibration mechanism enables the filter box 3 to vibrate when the material is discharged, effectively preventing clogging during the screening process and improving screening efficiency. Simultaneously, the vibration also helps the material distribute more evenly within the filter box 3, further enhancing screening quality. The high-speed rotating rollers 13 and the interlaced crushing blades 14 on the two rollers 13 efficiently crush the corn kernels to achieve the desired degree of crushing. This crushing method combines shearing and impact, ensuring thorough crushing of the corn and improving the crushing effect.
