Description

Technical Field

[0001] This invention relates to the field of grain conveying devices, specifically a grain conveying device for flour processing. Background Technology

[0002] Flour is a staple food in most parts of northern China, and a wide variety of foods are made from it, each with its own unique flavor. The "flour" we commonly refer to is wheat flour, that is, flour milled from wheat. Names like "high-gluten wheat flour" refer to what we usually call wheat flour. Wheat flour is categorized by performance and use into specialty flour, general-purpose flour, and fortified flour; by refinement into first-grade special flour, second-grade special flour, standard flour, and ordinary flour; and by gluten strength into high-gluten flour, medium-gluten flour, and low-gluten flour. Conveying devices are used in flour processing to transport the grain raw materials. In the flour processing industry, grain is the main raw material, and its efficient and stable transportation is crucial to ensuring continuous production. Traditional grain conveying devices often have some shortcomings in practical applications.

[0003] Traditional grain conveying devices for flour processing suffer from several problems. Structurally, the support frame and base lack stability, easily deforming under prolonged high loads. A loose base can reduce stability and even cause safety accidents. Functionally, they are limited, unable to adapt to different grain characteristics. Conveying fine grains easily leads to clogging, while conveying large or heavy grains is inefficient, and the lack of effective screening functions increases the burden and cost of subsequent processing. Regarding angle adjustment, most traditional devices lack flexible adjustment functions, making precise angle adjustment difficult and potentially damaging components and affecting stability during the adjustment process. In terms of arch breaking, traditional devices lack effective arch breaking structures, leading to easy grain blockage requiring manual arch breaking, increasing labor intensity and disrupting production continuity.

[0036] The angle adjustment mechanism 1 also includes a first rotating shaft connecting block 113. The outer surface of the first rotating shaft connecting block 113 is rotatably connected to a first through hole connecting block 114. The outer surface of the first through hole connecting block 114 is fixedly connected to a hydraulic pump 115 and a first connecting rod 116. The outer surface of the first connecting rod 116 is slidably connected to a sleeve rod 117. The output end of the hydraulic pump 115 is rotatably connected to a connecting column 118. The outer surface of the connecting column 118 is fixedly connected to a first collar 119 and a second collar 120. The outer surface of the second collar 120 is fixedly connected to a second connecting rod 121. The outer surface of the second connecting rod 121 is fixedly connected to a third collar 122.

[0037] The sleeve rod 117 is slidably connected to the outer surface of the second support column 109, and the sleeve rod 117 is fixedly connected to the lower surface of the third rectangular sleeve 110. The first connecting rod 116 is rotatably connected to the connecting column 118. By setting the angle adjustment mechanism 1, the hydraulic pump 115 can accurately adjust and fix the angle of the screening cylinder 202. During the angle adjustment process, thanks to the structure of the first corrugated pipe 103 and the second corrugated pipe 112, it can be ensured that no adverse effects are caused to the first support column 101, the second support column 109 and the screening cylinder 202, providing a strong guarantee for the efficient operation and stable work of the grain conveying device for flour processing.

[0038] The screening and conveying mechanism 2 includes a screening cylinder 202. A first slot 201 is provided inside the screening cylinder 202, which is engaged with a second corrugated pipe 112. A second slot 203 is provided on the outer surface of the screening cylinder 202. An annular column 212 is fixedly connected to the outer surface of the screening cylinder 202. An inner sleeve 207 is engaged on the outer surface of the annular column 212. An outer sleeve 206 is fixedly connected to the outer surface of the inner sleeve 207. A discharge groove 208 is provided inside the outer sleeve 206. An electromagnet 205 is fixedly connected inside the outer sleeve 206. A first locking block 204 is engaged inside the second slot 203. Screening holes 209 are provided inside the screening cylinder 202 and the inner sleeve 207. A gear 211 is rotatably connected to the outer surface of the screening cylinder 202. A motor 210 is fixedly connected to the outer surface of the gear 211.

[0039] The screening cylinder 202 is internally fixedly connected with a threaded sleeve. The left side of the screening cylinder 202 is connected to the first corrugated pipe 103 through a slot. The screening cylinder 202 has a second slot 203 on both sides and a first locking block 204 is connected to it. The outer surface of the first locking block 204 is in contact with the outer surface of the electromagnet 205. The motor 210 is fixedly connected to the inner surface of the third sleeve 122. By setting up the screening and conveying mechanism 2, not only can the quality of the grain be improved and non-compliant flat particles be removed through the screening cylinder 202, but also purer grain raw materials can be provided for subsequent processing. Furthermore, the screening holes 209 can be adjusted by the electromagnet 205, the first locking block 204, the screening cylinder 202 and the inner sleeve 207 to meet different screening requirements.

[0040] The working principle of this embodiment is as follows: When using the grain conveying device for flour processing, the motor 210 starts and rotates, driving the gear 211 to rotate. The gear 211 drives the screening cylinder 202 to rotate. At this time, grain is put into the feed port 102, and the grain spirals upward inside the screening cylinder 202 through the threaded sleeve inside the screening cylinder 202. It is screened through the screening holes 209, falls into the surface of the outer sleeve 206 through the screening holes 209 inside the inner sleeve 207, and flows out of the outer sleeve 206 through the discharge chute 208. The screened grain flows into the next device through the discharge port 111 through the second corrugated pipe 112. When it is necessary to adjust the screening holes 209 of the device, the electromagnet 205... The first locking block 204 is pushed outward to disengage from the second locking slot 203. At this time, the motor 210 drives the screening cylinder 202 to rotate, causing the screening holes 209 on the screening cylinder 202 to misalign with the screening holes 209 on the inner sleeve 207, thus reducing the screening gap. At this time, the electromagnet 205 pushes the first locking block 204 to tightly engage with the second locking slot 203, realizing rotational screening. When angle adjustment is required, the hydraulic pump 115 starts to push the connecting column 118, and through the connecting column 118, drives the first connecting rod 116 to rotate around the axis of the first rotating shaft connecting block 113, thereby causing the first collar 119, the second collar 120, and the connecting column 118 to rotate around the axis of the first rotating shaft connecting block 113. This causes the screening cylinder 202, outer sleeve 206, and inner sleeve 207 to rotate around the axis of the first rotating shaft connecting block 113. The first corrugated pipe 103 and the second corrugated pipe 112 achieve a tight fit between the feed inlet 102 and the discharge outlet 111 without affecting the rotation of the screening cylinder 202. When the screening cylinder 202 rotates, the first connecting rod 116 pushes the sleeve rod 117 to move. The sleeve rod 117 pushes the third rectangular sleeve 110 to slide on the outer surface of the second support column 109, so that the discharge outlet 111 moves up and down. The first rectangular sleeve 104, the first rectangular connecting column 105, the second rectangular sleeve 108, and the second rectangular connecting column 107 stabilize the position of the discharge outlet 111 and the feed inlet 102.

[0041] Example 2: Please refer to Figures 8-9Based on Embodiment 1, the present invention provides a technical solution: the arch-breaking and cleaning mechanism 3 includes a first support frame 301, the first support frame 301 is fixedly connected to the outer surface of the second connecting rod 121, a bearing 302 is fixedly connected to the outer surface of the first support frame 301, a first lead screw 303 is rotatably connected inside the bearing 302, a second support frame 304 is connected to the outer surface of the first lead screw 303, a cleaning collar 305 is slidably connected to the outer surface of the first lead screw 303, and a first... The first slider 306 has a first connecting block 307 fixedly connected to its outer surface, a second connecting block 308 fixedly connected to its outer surface, a second lead screw 309 fixedly connected to its outer surface, a second slider 310 slidably connected to its outer surface, a baffle 311 fixedly connected to its outer surface, a metal spring 312 fixedly connected to its outer surface, and a brush head 313 fixedly connected to its outer surface.

[0042] The second support frame 304 is rotatably connected to the first lead screw 303 via the bearing 302, and the second lead screw 309 is fixedly connected to the outer surface of the first slider 306. By setting the arch-breaking and cleaning mechanism 3, various impurities attached to the inner surface can be thoroughly removed by the brush head 313 and the metal spring 312 without damaging the structure of the screening cylinder 202. It can also destroy the arch structure. Not only can the baffle 311 and the second lead screw 309 prevent grain blockage and improve conveying efficiency, but it can also ensure that the grain is evenly distributed in the screening cylinder 202, thereby improving the quality and effect of screening.

[0043] By setting up the above mechanisms, the screening cylinder 202 and the inner sleeve 207 achieve precise screening of grains, the screening cylinder 202 and the motor 210 achieve efficient conveying, and the hydraulic pump 115, the baffle 311 and the brush head 313 achieve flexible angle adjustment, inner surface cleaning and arch breaking and other functions, ensuring the continuity and smoothness of the entire processing flow in the grain processing stage.

[0044] The working principle of this embodiment is as follows: When using the grain conveying device for flour processing, when it is necessary to clean the surface of the sieving cylinder 202, the first lead screw 303 rotates, driving the cleaning collar 305 and the first slider 306 to rotate. The first slider 306 drives the first connecting block 307 to rotate, and through the metal spring 312, the brush head 313 contacts the inner surface of the sieving cylinder 202 and cleans it during rotation. The cleaning collar 305 cleans the outer surface of the first lead screw 303, making its rotation smoother. At the same time, the baffle 311 breaks the arched accumulation of grains during rotation. The movement of the second slider 310 on the surface of the second lead screw 309 adjusts the arch-breaking effect, avoids grain blockage, and improves conveying efficiency.
