Description

Technical Field

[0001] This utility model relates to the field of wheat milling and screening technology, specifically to an automated high-square flat sieve device for wheat milling. Background Technology

[0002] Milling is the most important and common processing method for wheat. In wheat milling, the wheat is first cleaned and impurities are removed. Then, the cleaned and impurities-removed wheat is sent to a milling machine for milling. Finally, the milled wheat is sent to a high-square flat screen for screening and grading.

[0003] According to the authorized patent 'CN216757132U', a high-square flat sieve plate pressing device for wheat milling includes a sieve box. The sieve box has side channels on both sides, and several sets of pneumatic telescopic rods are installed in the two sets of side channels. A front channel is provided at the front of the sieve box, and a sieve door is provided in the front channel. Mounting blocks are fixedly installed at the four corners on both sides of the sieve door. Multiple sieve grids are provided inside the sieve box. Each sieve grid has two symmetrically arranged combination grooves on its front end face. A connecting cone rod is fixedly installed on the end face of each combination groove. Several combination blocks are symmetrically arranged on the inner end face of the sieve door. An elastic mechanism is provided between each set of combination blocks on both horizontal sides. A connecting cone groove is provided on the end face of each combination block. Limiting mechanisms are symmetrically arranged on both sides of the connecting cone groove. This invention uses horizontal and vertical pressing methods to ensure the sealing effect between multiple sieve grids.

[0004] During the use of the above technical solution, because the device uses a fixed-position dust suction port or brush to clean impurities, it cannot cover the entire screening area, resulting in a large amount of impurities remaining on the surface of the screening frame. These residual impurities will mix with flour in the subsequent screening process, reducing product quality. At the same time, the accumulation of impurities may also clog the screening mesh, affecting screening efficiency and increasing equipment maintenance costs.

[0005] Therefore, an automated high-square flat sieve device for wheat milling is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] Please see Figures 1-7 This utility model provides a technical solution:

[0033] An automated wheat milling high-square flat sieve device includes a machine body shell 1, and a flat sieve mechanism 4 and a debris cleaning mechanism 5 are arranged inside the machine body shell 1;

[0034] The flat screen mechanism 4 includes a hydraulic cylinder 41, a lifting rod 42 is fixedly connected to the bottom of the hydraulic cylinder 41, and a screening frame 43 is fixedly connected to the bottom of the lifting rod 42.

[0035] The debris cleaning mechanism 5 includes a motor 51, a lead screw 52 fixedly connected to the output end of the motor 51, a collar 53 threadedly connected to the outer side of the lead screw 52, ​​a suction plate 55 fixedly connected to the bottom of the collar 53, a suction fan 56 fixedly connected to the outer side of the outer casing 1, a telescopic hose 57 fixedly connected to the outer side of the suction fan 56, and a discharge pipe 58 fixedly connected to the outer side of the suction fan 56.

[0036] It should be noted that: a controller 2 is provided on the outside of the outer shell 1, a feed hopper 3 is fixedly connected to the top of the outer shell 1, a limiting block 44 is fixedly connected to the outside of the screening frame 43, a moving groove 45 is provided in the inner wall of the outer shell 1, and the limiting block 44 is slidably connected inside the moving groove 45. A transmission rod 54 is fixedly connected to the top of the collar 53, a limiting groove is provided in the inner top wall of the outer shell 1, and the top of the transmission rod 54 is slidably connected inside the limiting groove.

[0037] Furthermore: the lifting rod 42 is movably connected to the inside of the outer casing 1, the screening frame 43 is movably connected to the inside of the outer casing 1 via the lifting rod 42, the lead screw 52 is rotatably connected to the inside of the outer casing 1, and the lead screw 52 is located above the screening frame 43, the end of the telescopic hose 57 away from the suction fan 56 is fixedly connected to the inside of the suction plate 55, the suction plate 55 is movably connected to the top of the screening frame 43 via the collar 53, and the length of the suction plate 55 is the same as the inner width of the screening frame 43.

[0038] Specifically: Hydraulic cylinder 41 achieves vertical movement of lifting rod 42 by precisely controlling the input and output of hydraulic oil. When wheat enters the machine casing 1 from the feed hopper 3, hydraulic cylinder 41 is activated, and lifting rod 42 drives screening frame 43 to move downward. Limiting block 44 on the outside of screening frame 43 slides in moving groove 45. This limiting design not only ensures that screening frame 43 remains stable during lifting and lowering, avoiding shaking that affects screening effect, but also prevents screening frame 43 from shifting and causing material spillage. By adjusting the height of screening frame 43, the screening time and force of wheat in screening frame 43 can be changed, thereby adapting to the screening needs of wheat of different qualities and improving the flexibility and accuracy of screening.

[0039] Meanwhile, the transmission rod 54 at the top of the collar 53 slides in the limiting groove, further ensuring the stability of the movement of the collar 53. The suction plate 55 is fixed at the bottom of the collar 53, and its length is the same as the inner width of the screening frame 43, which can completely cover the top area of ​​the screening frame 43.

[0040] As a further implementation of this solution, the outer casing 1 of the machine body is provided with a discharge mechanism 6. The discharge mechanism 6 includes a slide 61. One end of the slide 61 is fixedly connected to the movable tube 62. A telescopic rod 63 is slidably engaged inside the movable tube 62. A connecting block 64 is fixedly connected to the end of the telescopic rod 63 away from the movable tube 62. A return spring 65 is sleeved on the telescopic rod 63. A collection groove 66 is fixedly connected to the top of the connecting block 64. A sealing plate 67 is fixedly connected to the outside of the collection groove 66.

[0041] It should be noted that: the slide 61 is opened in the inner bottom wall of the outer shell 1, the connecting block 64 is slidably connected to the inside of the slide 61, the collection trough 66 is slidably connected to the inside of the outer shell 1, and the collection trough 66 is located directly below the screening frame 43, and the sealing plate 67 is snapped onto the outside of the outer shell 1.

[0042] Furthermore, the controller 2 plays a core control role. Operators can preset the lifting height and frequency of the flat sieve mechanism 4, the cleaning time and path of the impurity cleaning mechanism 5, and the collection timing of the discharge mechanism 6 through the controller 2. When wheat enters the outer shell 1 from the feed hopper 3, the flat sieve mechanism 4 starts screening. During the screening process, the impurity cleaning mechanism 5 cleans the impurities on the surface of the screening frame 43 according to the preset program. After screening is completed, the discharge mechanism 6 collects and stores the screened flour. The close cooperation between the various mechanisms realizes the fully automated process of wheat screening, impurity cleaning, and flour collection, which greatly improves production efficiency, reduces labor costs, and ensures the quality and stability of flour production.

[0043] Work process: Wheat flour is fed into the outer shell 1 of the machine body through the feed hopper 3. The feed hopper 3 provides a convenient and directional inlet for the raw materials, ensuring that the wheat flour can smoothly enter the subsequent processing stage.

[0044] The controller 2 starts the hydraulic cylinder 41 in the flat screen mechanism 4. The hydraulic cylinder 41 drives the lifting rod 42 to perform vertical extension and retraction. The lifting rod 42 drives the bottom screening frame 43 to move up and down inside the machine body shell 1. The limiting block 44 on the outside of the screening frame 43 slides and engages with the moving groove 45 on the inner wall of the machine body shell 1 to ensure that the screening frame 43 will not deviate or shake during the lifting process, thus achieving stable dynamic screening. During the up and down movement of the screening frame 43, wheat flour of different particle sizes is effectively separated due to its own gravity and the filtering effect of the screen, meeting diverse production needs.

[0045] The debris generated during the screening process is automatically cleaned by the debris cleaning mechanism 5. The controller 2 starts the motor 51, and the output end of the motor 51 drives the lead screw 52 to rotate inside the machine body shell 1. Due to the threaded connection, the collar 53 on the outside of the lead screw 52 moves back and forth in a straight line along the lead screw 52. The suction plate 55 at the bottom of the collar 53 moves synchronously above the screening frame 43. The length of the suction plate 55 is the same as the inner width of the screening frame 43, ensuring that it can cover the entire area above the screening frame 43. At the same time, the suction fan 56 starts and is connected to the suction plate 55 through the telescopic hose 57. During the movement of the suction plate 55, the debris on the screening frame 43 is sucked away in time to avoid the debris residue affecting subsequent screening and product quality. The sucked-out debris is discharged through the discharge pipe 58 by the suction fan 56. The transmission rod 54 at the top of the collar 53 slides with the limiting groove on the inner top wall of the machine body shell 1 to ensure the stability of the collar 53 and the suction plate 55 during the movement.

[0046] The qualified wheat flour falls into the collection trough 66 located directly below the screening frame 43. When the collection trough 66 is full of wheat flour, the operator pulls the sealing plate 67, causing the connecting block 64 to slide in the slide trough 61. The telescopic rod 63 pulls the return spring 65 in the movable tube 62, allowing the collection trough 66 to be pulled out from the inside of the machine body shell 1 for unloading. After unloading, the sealing plate 67 is released. Under the action of the return spring 65, the telescopic rod 63 drives the connecting block 64 and the collection trough 66 to automatically reset. The sealing plate 67 on the outside of the collection trough 66 is engaged with the outside of the machine body shell 1 to ensure the sealing of the machine body during the discharge process, prevent dust from overflowing, and maintain a good working environment.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
