Description

Technical Field

[0001] This utility model relates to the technical field of millet processing equipment, specifically a milling device for millet processing and production. Background Technology

[0002] Millet, also known as foxtail millet, has high nutritional value and is usually ground into millet flour for consumption.

[0003] In existing technologies, millet grinding devices typically consist of a feed inlet, a grinding mechanism, a screen, and a discharge outlet. The grinding mechanism includes a control system, a motor, and grinding blades. During use, millet is usually poured directly from the feed inlet, making it impossible to control the feed rate. This can easily lead to feed inlet blockage and device overload, thus affecting the grinding effect. In addition, the grinding blades of the grinding mechanism are prone to wear after long-term use, and the screen is prone to blockage after long-term use. Furthermore, the existing grinding blades and screens are inconvenient to replace, affecting the use of the device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned issues and provide a milling device for millet processing with controllable feed rate and convenient replacement of the milling mechanism and screen.

The upper and lower side walls of the milling barrel are respectively provided with a feed inlet and a discharge outlet. One end of the opening of the milling barrel is provided with a detachable round cover, and the other end of the round cover is provided with a motor. The output end of the motor passes through the round cover and is provided with crushing blades. The side wall of the round cover facing the milling barrel is provided with a screen corresponding to the discharge outlet. A hopper is provided above the feed inlet. A limiting plate is slidably inserted between the hopper and the milling barrel. The limiting plate is a curved arc structure, and the upper end of the limiting plate is provided with a rectangular groove corresponding to the feed inlet.

[0006] As an improvement, the right end of the grinding barrel is provided with a corresponding internal thread blind hole, and the end of the round cover away from the grinding barrel is inserted with a limiting bolt that matches the internal thread blind hole.

[0007] As an improvement, the number of crushing blades is multiple and they are evenly arranged along the circumference. The crushing blades have an L-shaped structure and the vertical end is inclined towards the side close to the center of the round cover.

[0008] As an improvement, the screen is larger than the discharge port, and the front and rear ends of the screen are inclined surfaces that slope downwards toward the side away from the center of the screen.

[0009] As an improvement, one end of the limiting plate is connected to an increasing plate, and the other end is provided with a connecting rod.

[0010] As an improvement, a second motor is provided at the left end of the grinding barrel, and a rotating plate is provided between the second motor and the connecting rod.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] 1. By setting a detachable round cover, and placing the grinding blades and screen on the round cover, they can be removed from the grinding barrel along with the round cover for easy replacement;

[0013] 2. A limiting plate is slidably installed between the feed inlet and the grinding barrel. The feed rate can be controlled by pulling the limiting plate and the material can be discharged by adjusting the position of the limiting plate, so as to avoid the feed inlet from being blocked and the device from being overloaded.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Combined with appendix Figure 1-4 A milling device for millet processing includes a milling barrel 1 with its opening facing horizontally to the right. The upper and lower side walls of the milling barrel 1 are respectively provided with a feed inlet 3 and a discharge outlet 4. One end of the opening of the milling barrel 1 is provided with a detachable round cover 2. The right end of the milling barrel 1 is provided with a corresponding internally threaded blind hole 11. The end of the round cover 2 away from the milling barrel 1 is inserted with a limiting bolt 12 that mates with the internally threaded blind hole 11, so that the round cover 2 and the milling barrel 1 are connected by the limiting bolt 12.

[0021] The other end of the round cover 2 is equipped with a motor 5. The output end of the motor 5 passes through the round cover 2 and is equipped with crushing blades 6. There are multiple crushing blades 6, which are evenly arranged along the circumference. The crushing blades 6 have an L-shaped structure, and one vertical end is inclined towards the side closer to the center of the round cover 2. By starting the motor 5, the crushing blades 6 can be rotated to grind the millet into powder. The side wall of the round cover 2 facing the grinding barrel 1 is equipped with a screen 7 corresponding to the discharge port 4. The screen 7 is larger than the discharge port 4. The front and rear ends of the screen 7 are inclined downwards towards the side away from the center of the screen 7, so that millet powder smaller than the aperture of the screen 7 passes through the screen 7 and is discharged from the discharge port 4.

[0022] A hopper 8 is provided above the feed inlet 3. A limiting plate 9 is slidably inserted between the hopper 8 and the grinding barrel 1. The limiting plate 9 has a curved arc structure. One end of the limiting plate 9 is connected to a heightening plate 13, and the other end is provided with a connecting rod 14. A second motor 15 is provided at the left end of the grinding barrel 1. A rotating plate 16 is provided between the second motor 15 and the connecting rod 14, so that the limiting plate 9 rotates back and forth with the second motor 15. A rectangular groove 10 corresponding to the feed inlet 3 is provided at the upper end of the limiting plate 9, so that millet can pass through the overlapping part of the rectangular groove 10 and the feed inlet 3 and enter the grinding barrel 1, thereby controlling the amount of millet fed and preventing the feed inlet 3 from being blocked.

[0023] In the initial state of this invention, the round cover 2 is installed on the left side of the grinding barrel 1, and the limiting plate 9 completely covers the feed inlet 3. Millet is poured into the hopper 8, and the motor 5 is started to make the crushing blades 6 rotate, which can crush the millet entering the grinding barrel 1 into powder. The motor 15 is then controlled to make the limiting plate 9 rotate. The part of the rectangular groove 10 that intersects with the feed inlet 3 forms the passage space for millet, allowing millet to enter the grinding barrel 1 and be crushed into powder. Millet powder smaller than the aperture of the screen 7 passes through the screen 7 and is discharged from the discharge outlet 4. The limiting plate 9 can control the amount of millet fed in, avoiding blockage of the feed inlet 3 or overload of the device. After use, the round cover 2 can be removed by unscrewing the limiting bolt 12 to facilitate the replacement of the crushing blades and screen 7 in the grinding barrel 1, so that the device can maintain the effect of millet processing and grinding.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
