Description

Technical Field

[0001] This utility model belongs to the field of grain processing technology, and specifically relates to a grinding device for grain processing. Background Technology

[0002] In the grain processing industry, the production of meal replacement powders has become an important branch. Meal replacement powders are typically made from carefully selected grains, beans, potatoes, and other raw materials through fine grinding and mixing, aiming to provide quick, convenient, and nutritionally balanced food alternatives. However, traditional grain processing equipment, especially in the grinding stage, often lacks effective screening mechanisms, resulting in the presence of incompletely ground powder in the final product. This affects the taste and solubility of the meal replacement powder, and incompletely ground powder may also cause clumping when prepared, impacting the overall eating experience.

[0003] A patent document once disclosed a crushing and grinding device for grain processing. Although it solved the above-mentioned technical problems, the second filter screen located above the second discharge port could not move. If the second filter screen could not move, not only would the filtration efficiency be poor, but the second filter screen might also be unable to effectively handle the large amount of powder generated during the grinding process. This could lead to the accumulation of powder on the second filter screen, eventually causing blockage. The blockage of the second filter screen would greatly reduce the working efficiency of the crushing and grinding device, increase the frequency of maintenance and cleaning, and may affect the quality of the final product.

[0004] Therefore, it is necessary to design a grinding equipment for grain processing to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above technical problems, this utility model proposes a grinding equipment for grain processing. It adopts a crushing chamber and a grinding chamber for preliminary crushing and fine grinding of grain. At the same time, through the cooperation of the drive mechanism and the reciprocating mechanism, the screening screen moves back and forth on the slide, which can more effectively separate grain powder and ensure the uniformity of powder particles, thereby improving the screening effect and the product quality of meal replacement powder.

[0006] The technical solution of this utility model is:

[0007] This utility model proposes a grinding device for grain processing, comprising:

[0053] like Figures 1-5 As shown, this utility model provides a grinding device for grain processing, comprising:

[0054] Box 1, Box 1 includes a crushing chamber 10 and a grinding chamber 11. A set of opposing crushing rollers 100 are arranged in the inner cavity of the crushing chamber 10, and a grinding roller 110 is arranged in the inner cavity of the grinding chamber 11.

[0055] One end of the crushing roller 100 extends to the outside of the crushing chamber 10; one end of the grinding roller 110 extends to the outside of the grinding chamber 11, and the crushing roller 100 is rotatably connected to the crushing chamber 10, and the grinding roller 110 is rotatably connected to the grinding chamber 11.

[0056] The drive unit is used to drive the crushing roller 100 and the grinding roller 110 to rotate;

[0057] The top of the crushing chamber 10 is connected to the feed inlet 101, and the bottom of the grinding chamber 11 is connected to the discharge outlet 111;

[0058] Screening mesh 2 is slidably connected to the housing 1 and is located directly below the discharge port 111;

[0059] The reciprocating mechanism is used to drive the screening net 2 to perform reciprocating motion;

[0060] The drive unit drives the reciprocating mechanism through a bevel gear assembly.

[0061] The drive unit includes:

[0062] Two meshing gears 3 are fixed coaxially with the crushing roller 100;

[0063] The first pulley 30 and the second pulley 31 are connected by a belt 300. The first pulley 30 is coaxially fixed with the grinding roller 110.

[0064] Motor 32, the output shaft of motor 32 is coaxially fixed with gear 3; second pulley 31 is coaxially fixed with another gear 3.

[0065] The diameter of the first pulley 30 is larger than the diameter of the second pulley 31.

[0066] The bottom of the motor 32 is connected to the support base 320, and one end of the support base 320 is connected to the outer wall of the crushing chamber 10.

[0067] The two opposite sides of the screening mesh 2 are connected to sliding bars 20, and the box body 1 is connected to two symmetrical slide rails 12, which are slidably connected to the sliding bars 20.

[0068] Reciprocating mechanisms include:

[0069] Hinged rod 4 is rotatably connected to screen 2;

[0070] Cam 40 is coaxially fixedly connected to rotating shaft 41, and the end of hinge rod 4 away from screen 2 is rotatably connected to the protruding end of cam 40.

[0071] The grinding chamber 11 has a fixed plate 112 connected to its outer wall, and the rotating shaft 41 is rotatably connected to the fixed plate 112.

[0072] The bevel gear assembly includes:

[0073] Bevel gear 5 is coaxially fixed with the first pulley 30.

[0074] Bevel gear 250 meshes with bevel gear 15, and bevel gear 250 is fixed coaxially with rotating shaft 41.

[0075] A collection tube 6 is located directly below the screening mesh 2.

[0076] Working principle:

[0077] The grain is fed into the crushing chamber 10 through the feed inlet 101. Inside the crushing chamber, there is a set of opposing crushing rollers 100. The grain is squeezed and rubbed between the crushing rollers 100 to achieve preliminary crushing.

[0078] In the grinding process, the drive unit drives the crushing roller 100 and the grinding roller 110 to rotate through the bevel gear assembly. The crushing roller 100 crushes the grain initially, and then the grain enters the grinding chamber 11 through the crushing chamber 10. In the grinding chamber 11, the grain is further ground by the grinding roller 110, making the grain powder finer.

[0079] Screening and collection: Screening screen 2 is located directly below the discharge port 111 at the bottom of grinding chamber 11. The drive unit drives the reciprocating mechanism through the bevel gear assembly, causing the screening screen 2 to reciprocate. Screening screen 2 screens out the ground grain powder, and the powder that is not thoroughly ground is intercepted by screening screen 2, thereby improving the quality of the product. The screened grain powder falls into the collection cylinder 6 below through screening screen 2, completing the collection.

[0080] The drive unit operates by including a motor 32, two meshing gears 3, a first pulley 30, and a second pulley 31. When the motor 31 is started, its output shaft drives the gears 3 to rotate. The gears 3 are coaxially fixed with the crushing roller 100, thus achieving preliminary crushing of the grain. The first pulley 30 and the second pulley 31 are connected by a belt 300. The first pulley 30 is coaxially fixed with the grinding roller 110, and the second pulley 31 is coaxially fixed with another gear 3, thus achieving rotation of the grinding roller 110. The rotation speed of the grinding roller 110 is less than that of the crushing roller 100, resulting in finer grinding of the grain.

[0081] The reciprocating motion of the screening screen 2 causes the first pulley 30 to rotate, which in turn drives the first bevel gear 5 to rotate. When the first bevel gear 5 rotates, it drives the second bevel gear 50 to rotate. When the second bevel gear 50 rotates, it drives the cam 50 to rotate. When the cam 50 rotates, it drives the hinge rod 4 to move, which in turn drives the screening screen 2 to reciprocate in the slide rail 12. Through this reciprocating motion, the screening screen 2 can more effectively screen out thoroughly ground grain powder while intercepting incompletely ground powder, reducing clogging and material jamming. This improves the overall screening efficiency, enhances the taste and solubility of the meal replacement powder, and prevents large clumps from forming when the meal replacement powder is brewed.

[0082] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
