[0002] Wheat is a general term for plants in the genus *Triticum*, with common wheat being a representative species. It belongs to the Poaceae family and is a cereal crop widely cultivated worldwide. Wheat grains are a staple food for humans. After being ground into flour, they can be used to make bread, steamed buns, biscuits, noodles, and other foods. Fermentation can produce beer, alcohol, spirits, or biomass fuel. Wheat is generally ground into flour for easier processing.
[0003] In the existing technology, when using wheat milling machines to process wheat, it has been found that some wheat milling machines only have a single grinding method. The wheat put into the grinding equipment must reach the same grinding specification before it can be discharged. This method cannot grind wheat flour of different specifications according to actual needs, and its use is limited. Utility Model Content

[0023] Please see Figure 1-5This utility model provides a technical solution: a wheat mill, comprising: a milling cylinder 1, an inlet 101 fixedly embedded on one side of the top of the milling cylinder 1, the inlet 101 communicating with the inner cavity of the milling cylinder 1, a motor mounting base 102 fixedly connected to the other side of the top of the milling cylinder 1, a plurality of grinding walls 103 fixedly embedded in the interior of the milling cylinder 1 at equal intervals from top to bottom, a plurality of grinding blocks 104 fixedly connected in a circular pattern inside the plurality of grinding walls 103, the density of the grinding blocks 104 inside the plurality of grinding walls 103 gradually increasing from top to bottom, a plurality of cleaning doors 105 connected to the surface of the milling cylinder 1 by hinges, a second motor mounting base 106 fixedly connected to both sides of the bottom of the surface of the milling cylinder 1, a vibration motor 107 fixedly connected to the bottom of the two second motor mounting bases 106, and a grinding assembly 2 and a screening and discharge assembly 3 arranged inside the milling cylinder 1.
[0024] Specifically: The output of motor 201 drives the conical grinding hammer 203 to rotate, and it is ground by the grinding blocks 104 and 204. After being ground by grinding blocks 104 and 204 multiple times from top to bottom, it finally falls to the bottom of the inner cavity of the grinding cylinder 1. This design realizes multi-stage progressive grinding and avoids high temperature damage to gluten caused by one-time grinding. The sieve plate 301 has a sieve hole diameter that gradually decreases from top to bottom, such as 100 mesh, 200 mesh, and 300 mesh. Wheat flour smaller than the sieve hole falls into the next layer of grinding wall 103 and conical grinding hammer 203 grinding combination, while wheat flour larger than the sieve hole is discharged from the discharge pipe 304. This design can produce wheat flour of different grinding degrees at the same time. One end of the cleaning door 105 is fixedly connected to a handle, which can be opened by holding the handle to process the inside of the grinding cylinder 1.
[0025] In one embodiment, the bottom of the grinding cylinder 1 is circumferentially and equidistantly connected with a plurality of connecting posts 108, each of which is fixedly fitted with a spring 109, and each of which is fixedly embedded with a connecting post 110 at the bottom of its inner cavity. The bottom of each of the connecting posts 110 is fixedly connected with a base plate 111, and each of the four corners of the bottom of the base plate 111 is fixedly connected with a support leg 112.
[0026] Specifically, such as Figure 1 As shown: The activated vibrating motor 107, in conjunction with the spring 109, causes the grinding cylinder 1 to vibrate. The vibrating grinding cylinder 1, in conjunction with the sieve plate 301, can sieve wheat.
[0027] In one embodiment, the grinding assembly 2 includes a motor 201, the output end of the motor 201 is fixedly connected to a rotating shaft 202, a plurality of conical grinding hammers 203 are fixedly sleeved on the surface of the rotating shaft 202, and a plurality of grinding blocks 204 are fixedly connected to the surface of the plurality of conical grinding hammers 203 at equal intervals around the circumference, and the density of the grinding blocks 204 on the surface of the plurality of conical grinding hammers 203 gradually increases from top to bottom.
[0028] Specifically, such as Figure 3-4 As shown: The conical grinding hammer 203 has a conical design. Powder falls onto the surface of the rotating conical grinding hammer 203. Under the action of centrifugal force, the powder moves towards the outer ring of the conical grinding hammer 203 and then falls into the gap between the conical grinding hammer 203 and the grinding wall 103. Under the action of grinding block one 104 and grinding block two 204, the powder is ground and finally falls from the bottom of the gap between the grinding wall 103 and the conical grinding hammer 203. The grinding block one 104 and grinding block two 204 inside the combination of grinding wall 103 and conical grinding hammer 203 have a gradually increasing density from top to bottom, achieving a gradually increasing grinding level.
[0029] In one embodiment, the screening and discharge assembly 3 includes multiple screening plates 301 and multiple arc-shaped discharge ports 302. The aperture of the multiple screening plates 301 gradually decreases from top to bottom. The surfaces of the multiple screening plates 301 are fixedly embedded inside the multiple grinding cylinders 1. The multiple screening plates 301 and the multiple grinding walls 103 are staggered from top to bottom. The interior of the multiple screening plates 301 is connected to the surface of the rotating shaft 202 through sealed bearings.
[0030] Specifically, such as Figure 3 As shown: The sealed bearing assembly is a common rotating seal structure suitable for high dust environments; the specific structure will not be described in detail here.
[0031] In one embodiment, a guide plate 303 is fixedly connected to one side of each of the multiple arc-shaped discharge ports 302, and a discharge pipe 304 is fixedly connected to the other end of each of the multiple arc-shaped discharge ports 302. The multiple discharge pipes 304 are connected to the inner cavities of the multiple arc-shaped discharge ports 302.
[0032] Specifically, such as Figure 5 As shown: Under the action of vibration, the wheat flour on the upper layer of the sieve plate 301 moves towards the outer ring of the sieve plate 301 while being driven around the rotating shaft 202, and is then blocked by the guide plate 303.
[0033] In one embodiment, the surface of the motor 201 is fixedly connected to the side of the motor mounting base 102, the two ends of the surface of the rotating shaft 202 are connected to the two ends of the grinding cylinder 1 through sealed bearings, and the surfaces of the multiple conical grinding hammers 203 are correspondingly and movably embedded inside the multiple grinding walls 103.
[0034] Specifically, such as Figure 3 As shown: The motor 201 is fixedly connected to the side of the motor mounting base 102 to prevent the motor 201 from shaking during operation and affecting the normal operation of the equipment; the sealed bearing assembly is a common rotating seal structure suitable for high dust environments, and the specific structure will not be described here.
[0035] In one embodiment, the surfaces of one end of a plurality of arc-shaped discharge ports 302 are fixedly embedded inside the grinding cylinder 1 in a staggered manner, and the ends of the arc-shaped discharge ports 302 are arc-shaped and flush with the inner wall of the grinding cylinder 1. The plurality of arc-shaped discharge ports 302 communicate with the inner cavity of the grinding cylinder 1. The bottom of the inner cavity of one arc-shaped discharge port 302 is flush with the bottom of the inner cavity of the grinding cylinder 1, and the bottom of the inner cavity of the other plurality of arc-shaped discharge ports 302 is correspondingly flush with the top of the plurality of screening plates 301. The bottom of one guide plate 303 is attached to the bottom of the inner cavity of the grinding cylinder 1, and the bottom of the other plurality of guide plates 303 is correspondingly attached to the top of the plurality of screening plates 301.
[0036] Specifically, such as Figure 3 As shown: Wheat flour on the upper layer of the screening plate 301 is vibrated and enters the arc-shaped discharge port 302 through the guide plate 303, and finally exits from the discharge pipe 304.
[0037] Working principle: Connect this wheat mill to an external power supply device to provide power to the machine. The external controller is associated with and controls the vibration motor 107 and the motor 201.
[0038] The vibration motor 107 and motor 201 are started by an external controller. Wheat to be ground is fed into the feed inlet 101. The output end of motor 201 drives the rotating shaft 202 to rotate. The conical grinding hammer 203 rotates with the rotating shaft 202. The wheat falls onto the surface of the rotating conical grinding hammer 203. Under the action of centrifugal force and gravity, the wheat moves towards the outer ring of the conical grinding hammer 203 and then falls into the gap between the conical grinding hammer 203 and the grinding wall 103. It is ground by the action of grinding block 104 and grinding block 204. Finally, it falls from the bottom of the gap between the grinding wall 103 and the conical grinding hammer 203. After being ground by grinding block 104 and grinding block 204 multiple times from top to bottom, it finally falls to the bottom of the inner cavity of the grinding cylinder 1. The density of grinding block 104 and grinding block 204 inside the combination of grinding wall 103 and conical grinding hammer 203 gradually increases from top to bottom.
[0039] This design enables multi-stage progressive grinding of wheat flour, producing wheat flour of different grinding degrees simultaneously.
[0040] Inside the grinding cylinder 1, each grinding wall 103 and the lower part of the conical grinding hammer 203 grinding assembly are fixedly embedded with a sieve plate 301. The sieve hole diameter of the sieve plate 301 gradually decreases from top to bottom, such as 100 mesh, 200 mesh, and 300 mesh. The vibration motor 107, in conjunction with the spring 109, can make the grinding cylinder 1 vibrate. The vibrating grinding cylinder 1 drives the sieve plate 301 to vibrate. Under the action of vibration, the wheat flour at the top of the sieve plate 301 moves towards the outer circle of the sieve plate 301 while being driven around the rotating shaft 202. During the movement, the wheat flour smaller than the sieve hole falls into the next grinding wall 103 and the conical grinding hammer 203 grinding assembly, while the wheat flour larger than the sieve hole is blocked by the guide plate 303 and enters the arc-shaped discharge port 302 through the guide plate 303, and finally exits from the discharge pipe 304.
[0041] This design allows the milling machine for wheat processing to discharge and collect wheat flour produced simultaneously at different grinding degrees.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
