Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flour production devices, in particular to a flour mill. Background Art
[0002] A wheat mill relies on external power (such as that generated by an electric motor) to grind wheat into small particles. These particles, once they reach the target size, become flour. Inside the mill, two rollers with angled teeth draw the grain into the gradually shrinking grinding opening, squeezing it. The different speeds of the rollers generate a grinding force that breaks the grain into powder.
[0003] The current wheat mill needs to use a screen to screen after grinding to remove larger particles and sieve out qualified small particles to collect as flour. Therefore, a separate screening device is required for screening after the grinding is completed. Not only is the structure complex, but it also takes up a lot of space, making it inconvenient to use. Utility Model Content
[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a grinding mill for solving the technical problem that the current grinding mill needs to be used in conjunction with an additional screening device, which makes it inconvenient to screen the ground particles.

[0011] The beneficial effects of adopting the technical solution of this utility model are:
[0012] The utility model is provided with a screen assembly on the discharge pipe, and the screen assembly includes two screen baskets arranged in parallel and slidably connected in a sliding channel provided on the discharge pipe. During the grinding process, the ground particles fall into the discharge pipe and are screened by the screen basket, separating the larger particles from the smaller particles. The screened-out large particles are discharged by sliding the screen assembly horizontally, so that flour with a qualified particle size can be directly discharged from the discharge pipe without the need for an additional screening device, taking up less space, and being more convenient to use. By arranging a screen at the bottom of the screen basket, one end of the screen is rotatably connected to the bottom of the screen basket, and the two screens are arranged back to back, and the connection ends of the two screens are both arranged in the middle of the screen assembly.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and do not limit the scope of the present invention.
[0018] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0020] The specific embodiments are as follows:
[0021] Example 1, as Figure 1-3 As shown, a mill includes a mill body 1, a feed hopper 2, and a discharge assembly. The mill body 1 is supported by a frame 4. The feed hopper 2 is provided at the top of the mill body 1 for adding wheat. The discharge assembly is provided at the bottom of the mill body 1 for discharging the ground powder.
[0022] The discharge assembly includes a discharge pipe 3 and a screen assembly 5. In this embodiment, the discharge pipe 3 is a square tube with a funnel-shaped receiving portion at the lower end. A sliding channel 31 extending transversely through the discharge pipe 3 is provided, and the screen assembly 5 is slidably connected within the sliding channel 31.
[0023] The screen assembly 5 includes two screen baskets 51, which are arranged side by side and connected to form a whole. The screen baskets 51 fit into the space inside the discharge pipe 3 so that the ground powder can be fully screened through the screen baskets 51. An opening is provided at the bottom of the screen basket 51 and a screen 53 is connected to the opening. One end of the screen 53 is connected to the side of the opening near the other screen basket 51 by a rotating connection. In this way, the screen assembly 5 slides horizontally in the sliding channel 31. After one screen basket 51 slides out of the sliding channel 31, under the action of the gravity of the screen 53 and the larger ground particles thereon, the movable end of the screen 53 flips downward, causing the larger particles of ground material on the screen 53 to fall and be discharged. The entire discharge process is completed automatically without the need for other operations, making it more convenient to use.
[0024] A stopper is provided in the middle of the top of the screen assembly 5, that is, at the connection between the two screen baskets 51. When the screen assembly 5 slides along the sliding channel 31, the stopper is located in the discharge pipe 3 and cooperates with the discharge pipe 3 to stop it, thereby preventing the screen assembly 5 from completely slipping off and causing trouble.
[0025] In this embodiment, the stopping member is a stopping plate 52 , which is vertically connected to the screen assembly 5 and extends upward, cooperating with the discharge pipe 3 to achieve a stopping effect.
[0026] In this embodiment, a vibration driving device is provided at the discharge pipe 3 to drive the screen assembly 5 to vibrate with a certain amplitude, thereby facilitating screening.
[0027] In this embodiment, the screen assembly 5 is driven manually, and the screen assembly 5 is driven to move laterally after a certain period of time, so as to discharge the large ground particles in the screen basket 51.
[0028] In other embodiments, a driving device such as a telescopic rod is provided on the frame to drive the screen assembly to achieve reciprocating movement. The screen assembly is driven electrically, which saves manpower and is more convenient to use. Other structures are not described here.
[0029] When the flour mill of this embodiment is in use, wheat is fed into the mill body 1 from the feed hopper 2. The ground grains enter the discharge pipe 3 and fall onto the screen basket 51. Screen 53 sieves the grains, which meet the required particle size and fall down to form the ground flour. Larger grains remain on the screen 53. After a certain period of time, the screen assembly 5 is driven to move laterally, causing the screen basket 51 containing the large-particle flour to slide out of the discharge pipe 3. Under the influence of its own gravity and the large-particle flour, the movable end of the screen 53 tilts downward, allowing the large-particle flour on it to be discharged. The discharged large-particle flour can then be added back to the mill body 1 for secondary grinding, thereby increasing the flour yield. After grinding in the mill body 1 and then sieving through the screen assembly 5, the flour of the required particle size is separated from the larger-particle flour. The qualified flour is discharged directly from the discharge pipe 3 without the need for an additional screening device. This not only saves space but also improves ease of use.
[0030] Furthermore, an extension plate 531 is provided at the movable end of the screen 53, and the thickness of the extension plate 531 is smaller than the screen 53. When the screen 53 closes the opening at the bottom of the screen basket 51, the extension plate 531 stops at the bottom of the screen basket 51 to prevent the screen 53 from rotating upward too much.
[0031] Furthermore, downwardly protruding sliding bars 54 are provided on the front and rear sides of the bottom of the screen assembly 5 , and the sliding bars 54 are connected to the slide rails 32 provided at the bottom of the sliding channel 31 to ensure the linear sliding travel of the screen assembly 5 .
[0032] Furthermore, a sliding ball 55 is provided at the bottom of the sliding bar 54. A plurality of sliding balls 55 are provided and are dispersedly arranged at the bottom of the sliding bar 54, so that the sliding bar 54 can slide more smoothly in the slide rail 32.
[0033] Furthermore, the slide rail 32 is an L-shaped track, which cooperates with the side wall of the sliding channel 31 to form a groove, which is simpler in structure and easier to implement. The sliding bar 54 is embedded in the groove for sliding.
[0034] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
