Description

Technical Field

[0001] This utility model relates to the field of grain auger conveying technology, and in particular to a grain auger conveying device for filtering large particles of impurities. Background Technology

[0002] In grain storage, processing, and transportation, auger conveyors have become the core equipment for achieving continuous grain transportation due to their advantages such as compact structure, stable conveying, and strong adaptability.

[0003] With the large-scale development of the grain industry, the market has put forward higher requirements for the purity of grain and the stability of equipment operation during the transportation process. In particular, in the treatment of large particulate impurities such as stones, straw, and clumps of broken grains, existing equipment has gradually revealed many shortcomings.

[0004] While existing grain auger conveyors achieve grain conveying, they primarily focus on conveying functionality and lack a dedicated grading and impurity filtration structure. Some devices, though equipped with simple screens, can only achieve single-precision screening. Either the screen openings are too large, leaving small particles of impurities behind, or the openings are too fine, easily causing blockages. Unfiltered large particles entering the auger conveying chamber not only accelerate the wear of the spiral blades and casing, reducing equipment lifespan, but also easily accumulate at corners or outlets, causing blockages and requiring shutdown for cleaning, severely impacting conveying efficiency. Furthermore, existing filtration devices generally suffer from poor maintenance convenience: screening components are mostly fixed installations, requiring disassembly and replacement of numerous connecting parts, making operation cumbersome; the impurity collection structure lacks sealing, easily leading to dust pollution, and impurity discharge requires manual assistance, making it unsuitable for automated production. In addition, a single screening stage is difficult to adapt to grain processing scenarios with varying impurity content. When the impurity content in the grain is high, incomplete screening can occur, increasing the cost of secondary impurity treatment in subsequent processes. Therefore, a large-particle impurity filtering grain auger conveyor is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a grain auger conveyor device for filtering large particles of impurities, aiming to solve the problems of existing grain auger conveyors lacking a graded filtration structure, being prone to clogging and wear, being inconvenient to maintain, and not being able to thoroughly screen.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a grain auger conveyor for filtering large particles of impurities, comprising an auger conveyor, wherein a primary screening component and a fine screening component are sequentially arranged on the top of the auger conveyor;

[0007] The fine screening assembly includes a fixed base, the outer wall of which is fixedly connected to the upper surface of the auger conveyor. A screen plate is attached to the bottom end of the fixed base. An assembly bolt is threaded between the fixed base and the screen plate. An insertion slot is provided on the outer wall of the fixed base. A material collection hood is provided on the outer side of the fixed base. An insertion clip is fixedly connected to the upper edge of the inner wall of the material collection hood.

[0008] As a further description of the above technical solution:

[0009] The material collection hood is provided in two, and the two material collection hoods are arranged in a mirror image along the central axis of the auger conveyor. A splicing clip is fixedly connected to the lower edge of the inner wall of one material collection hood, and a splicing slot is opened on the lower edge of the inner wall of the other material collection hood.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the splicing clip is movably engaged with the inner wall of the splicing slot, and the lower edge of the outer surface of both of the material collection hoods is fixedly connected with a waste discharge pipe.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the insert card is movably engaged with the inner wall of the insert card slot.

[0014] As a further description of the above technical solution:

[0015] The primary screening component includes a feeding hopper, the bottom end of which is fixedly connected to the upper surface of the auger conveyor.

[0016] As a further description of the above technical solution:

[0017] A sieve plate is fixedly connected to the inner wall of the feeding hopper, and a discharge valve is fixedly connected to the outer wall of the feeding hopper.

[0018] As a further description of the above technical solution:

[0019] The lower surface of the auger conveyor is provided with an installation slot, and the inner wall of the installation slot is adapted to the outer wall size of the screen plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the fine filtration of grain is achieved by using a fixed base to support and fix the fine sieve assembly, detachable sieve plate assembly bolts, insert clips for the material collection cover, quick assembly and disassembly of splicing clips and splicing slots, and discharge of impurities through a discharge pipe. This facilitates the replacement and cleaning of sieve plates, makes it convenient to collect and discharge large particles of impurities, and improves the equipment's filtration efficiency and maintenance convenience.

[0031] Reference Figure 1 , Figure 2 and Figure 4 The top of the auger conveyor 1 is equipped with a fine screening assembly 3, which is used to finely filter the grain after the initial screening to remove residual large particles and impurities. The fine screening assembly 3 includes a fixed base 31, the outer wall of which is fixedly connected to the upper surface of the auger conveyor 1. A screen plate 32 is attached to the bottom end of the fixed base 31. An installation groove is opened on the lower surface of the auger conveyor 1, and the inner wall of the installation groove is adapted to the outer wall size of the screen plate 32. An assembly bolt 33 is threadedly connected between the fixed base 31 and the screen plate 32. The fixed base 31 is used to support and fix the screen plate 32. The screen plate 32 can be detached and installed by the assembly bolt 33 for easy replacement and cleaning, thus achieving fine screening of the grain. An insertion slot 34 is opened on the outer wall of the fixed base 31, and a collection hood 35 is connected to the outer side of the fixed base 31. There are two collection hoods 35. The material collection hoods 35 are mirror images of the central axis of the auger conveyor 1. Insert clips 36 are fixedly connected to the upper inner walls of the two material collection hoods 35. The outer walls of the insert clips 36 are movably engaged with the inner walls of the insert slots 34. The material collection hoods 35 are used to collect large particles of impurities intercepted during the fine screening process.

The splicing clips 37 and splicing slots 38 cooperate to splice and fix the two material collection hoods 35. The discharge pipes 39 are used to discharge the collected large particles of impurities from the equipment.

[0032] Working principle: Grain is first fed into the feeding hopper 21 of the primary screening component 2. It undergoes preliminary screening in the feeding hopper 21 by passing through the screen plate 22. The screen plate 22 intercepts large particles of impurities, which are discharged through the discharge valve 23. After passing through the primary screening, the grain enters the auger conveyor 1 and simultaneously passes through the fine screening component 3. The screen plates 32, which are fixed by the fixed base 31, perform fine filtration on the grain, further intercepting residual large particles of impurities. These impurities are collected by two collection hoods 35 that are mirror-arranged along the central axis of the auger conveyor 1. The collection hoods 35 can be quickly disassembled and spliced ​​by the insertion clip 36 and the insertion slot 34 of the fixed base 31, and by the splicing clip 37 and the splicing slot 38 of the other collection hood 35. Finally, the impurities are discharged from the equipment through the discharge pipe 39. In addition, the screen plates 32 can be disassembled and replaced by the mounting bolts 33 for easy cleaning and maintenance, ensuring the continuous effectiveness of fine screening.
