Description

Technical Field

[0001] This utility model relates to the field of flour processing technology, and in particular to a grinding machine for wheat flour processing. Background Technology

[0002] Wheat is an annual or biennial herbaceous plant belonging to the Poaceae family and the Triticum genus. Its stems are erect, tufted, and can reach up to 100 cm in height. The leaf sheaths are loosely wrapped around the stem, the ligule is membranous, and the leaf blades are long and lanceolate. The spike-like inflorescence is erect, with spikelets containing numerous florets. The glumes are ovate, the lemma is oblong-lanceolate, and the palea is nearly equal in length to the lemma. Flowering and fruiting occur from May to July.

[0003] A Chinese patent, CN221951325U, discloses a wheat processing and grinding device. By using a support plate, a T-shaped rod, and a nut, adjusting the position of the nut removes the positional constraint of the support plate. The support plate can then move through a through-hole on the outer ring of the T-shaped rod, allowing the motor to move up and down, thus adjusting the position of the grinding disc. This changes the distance between the first and second grinding rods, controlling the particle size of the ground material and making the device more practical. However, adjusting the grinding disc's position using a nut is cumbersome and prone to metal fatigue over time, leading to loosening of metal parts and a heavy grinding disc. Adjusting the disc is time-consuming and laborious. Therefore, a wheat flour grinding machine is proposed to solve these problems. Utility Model Content

Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figure 1-3As shown, the present invention proposes a grinding mill for wheat flour processing, comprising a tank 1, a feed hopper 2, a sieve plate 5, and a grinding disc 7. The feed hopper 2 is connected to the top of the tank 1, the sieve plate 5 is connected to the inside of the tank 1, the grinding disc 7 is rotatably disposed inside the tank 1, and a grinding cover 3 is also included. The grinding cover 3 is slidably disposed inside the tank 1 and is located directly above the grinding disc 7. A lifting mechanism for driving the grinding cover 3 to rise and fall is provided inside the tank 1. Two cleaning brushes 6 are disposed above the sieve plate 5, and a driving mechanism for driving the two cleaning brushes 6 and the grinding disc 7 to rotate is provided inside the tank 1. Both cleaning brushes 6 are detachably connected to the rotating end of the driving mechanism.

[0022] In this invention, grinding rods are provided on the surface of the grinding disc 7 and the inner wall of the grinding cover 3. The grinding rods improve the grinding efficiency. The ground material is screened by the sieve plate 5. A drive mechanism drives two cleaning brushes 6 to sweep the material on the sieve plate 5 to prevent the material from clogging the sieve holes and improve the screening effect. The grinding cover 3 is driven to move up and down by a lifting mechanism. The telescopic tube 21 can extend and retract according to the vertical position of the grinding cover 3, but the material can still be introduced from the feed hopper 2 into the space between the grinding disc 7 and the grinding cover 3. The drive mechanism simultaneously drives the grinding disc 7 to rotate to grind the material. Slider blocks are connected to both the left and right sides of the grinding cover 3. The inner wall of the tank 1 is provided with a sliding groove. The sliding groove cooperates with the slider to limit the position of the grinding cover 3.

[0023] In an optional embodiment, a telescopic tube 21 connects the bottom end of the feed hopper 2 to the grinding cover 3.

[0024] In an optional embodiment, the lifting mechanism includes a first motor 41, a first rotating rod 42, two threaded rods 43, two first bevel gears 44, two second bevel gears 45, and two connecting frames 46. A support frame is connected to the top of the tank body 1. The first motor 41 is located on the right side of the support frame. One end of the first rotating rod 42 is coaxially connected to the output shaft of the first motor 41, and the other end is rotatably connected to the left side wall of the support frame. The two threaded rods 43 are rotatably located at the top of the tank body 1 and extend into its interior. The two connecting frames 46 are fixedly connected to the top of the grinding cover 3 and are threadedly connected to the two threaded rods 43 respectively. The two first bevel gears 44 are coaxially fixedly sleeved on the first rotating rod 42, and the two second bevel gears 45 are coaxially fixedly sleeved on the two threaded rods 43 respectively and mesh with the two first bevel gears 44 respectively.

[0025] It should be noted that when adjusting the up and down position of the grinding cover 3, the first motor 41 is started first to drive the first rotating rod 42 to rotate. The two first bevel gears 44 and the two second bevel gears 45 cause the two threaded rods 43 to rotate simultaneously, driving the two connecting frames 46 to move the grinding cover 3 up and down, thereby adjusting the distance between the grinding cover 3 and the grinding disc 7.

[0026] In an optional embodiment, the drive mechanism includes a second motor 81, a second rotating rod 82, and a fixing frame 83. The second motor 81 is disposed at the bottom end of the tank body 1. One end of the second rotating rod 82 is coaxially connected to the output shaft of the second motor 81, and the other end is rotatably connected to the top wall of the tank body 1. The fixing frame 83 is coaxially fixedly sleeved on the second rotating rod 82, and two cleaning brushes 6 are respectively inserted into the left and right ends of the fixing frame 83.

[0027] It should be noted that during grinding, the second motor 81 is started to drive the second rotating rod 82 to rotate, thereby driving the fixed frame 83 to rotate. The fixed frame 83 is connected to the two cleaning brushes 6 through a fixing component. By pressing the two fixing heads 832, the spring 833 is contracted, and then the fixing heads 833 are inserted into the appropriate fixing groove to fix the two cleaning brushes 6.

[0028] In an optional embodiment, the fixing frame 83 is provided with two sets of fixing components. Each set of fixing components includes a fixing plate 831, two fixing heads 832 and two springs 833. The fixing plate 831 is fixedly connected to the inside of the fixing frame 83. The two fixing heads 832 are slidably disposed inside the fixing frame 83 and extend to its front and rear sides respectively. The two springs 833 are respectively connected between the two fixing heads 832 and the front and rear sides of the fixing plate 831.

[0029] In an optional embodiment, both cleaning brushes 6 have fixing grooves at the front and back, which are adapted to the size of the fixing head 832.

[0030] In an optional embodiment, the bottom of the tank 1 is inclined, and a door is provided on the right side of the tank 1.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
