Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically to an improved structure of a spiral auger blade. Background Technology

[0002] Spiral auger blades, as key components in material conveying equipment, are widely used in the conveying of various bulk materials such as coal, grain, and chemical raw materials. Their design principle utilizes the thrust generated by the rotation of the spiral to transport materials from one end to the other, achieving continuous and efficient material transfer.

[0003] However, in practical applications, the performance and lifespan of auger blades are affected by a variety of factors, among which the gap between the blade edge and the inner surface of the cylinder wall is particularly prominent.

[0004] Specifically, to ensure smooth rotation of the auger blades and avoid direct friction with the cylinder wall, a gap is typically left between the blade edges and the inner surface of the cylinder wall during design. However, while this design solves the rotation problem, it introduces a new one—particulate materials easily seep into this gap during transport and, under the continuous rotation of the auger, cause severe wear on the blade edges. Over time, the blade edges gradually shorten due to wear, which not only directly affects the auger blades' feeding capacity, leading to a decrease in material conveying efficiency, but may also trigger a series of chain reactions such as material leakage and equipment failure, seriously affecting the stability and reliability of the entire material conveying system.

[0005] Especially when handling materials with strong adhesion or high hardness, the wear problem of auger blades is more severe, greatly shortening the service life of the equipment and increasing maintenance costs and downtime. Therefore, how to effectively solve the problem of edge wear of auger blades and improve their feeding and conveying capacity has become an urgent technical problem to be solved in the field of material conveying equipment technology. Utility Model Content

[0006] In view of this, the present invention provides an improved structure for a spiral auger blade. The present invention can prevent the spiral auger blade from being damaged by wear-resistant parts, thereby increasing the service life of the spiral auger blade. Furthermore, the wear-resistant parts can also ensure that the feeding capacity of the spiral auger blade is not reduced.

[0007] To solve the above-mentioned technical problems, this utility model provides an improved structure for a spiral auger blade, including a wear-resistant component fixedly connected to the side of the spiral auger blade away from the axis of rotation. The wear-resistant component is also spiral in shape. The wear-resistant component can reduce the wear on the edge of the spiral auger blade, thereby ensuring the feeding capacity of the spiral auger blade.

[0008] The wear-resistant parts are steel bars welded to the edge of the auger blades.

[0009] The wear-resistant parts are marked on the spiral auger blades to fix the wear-resistant parts at a designated position on the spiral auger blades. The marking structure can prevent excessive deviation of the predetermined position in the steel bar.

[0010] The marking structure consists of marking scale lines set on the auger blades.

[0011] The marking structure consists of a marking block fixed to the auger blades. The marking block has a spiral structure and is placed inside the steel reinforcement.

[0012] The marking block is fixed to the auger blades with bolts, making it easy to remove the marking block.

[0013] The marking block is also provided with countersunk holes for the corresponding bolts, and the ends of the bolts can be inserted into the countersunk holes. The corresponding countersunk holes are also provided with sealing plugs to prevent materials from entering the countersunk holes.

[0014] The cross-section of the marking block is a right-angled triangle structure, that is, the marking block has two corner sides and one inclined side. One of the two corner sides abuts against the auger blades, and the other corner side abuts against the wear-resistant parts. The marking block can prevent the wear-resistant parts from bending and deforming towards the shaft.

[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0016] 1. Reduce blade wear and extend service life: A wear-resistant component with a spiral structure is fixedly connected to the side of the auger blades away from the shaft. When materials are being transported, the wear-resistant component preferentially bears the friction and impact generated between the material and the inner surface of the cylinder wall, effectively preventing direct wear on the edges of the auger blades. This design greatly reduces the wear on the blade edges, significantly extends the overall service life of the auger blades, reduces equipment maintenance costs and downtime, and improves equipment efficiency and economy.

[0017] 2. Ensure feeding capacity and improve conveying efficiency: By incorporating wear-resistant components, the blade edges are prevented from shortening due to wear, thus ensuring that the auger blades' feeding capacity remains unaffected. During material conveying, the auger blades can stably and efficiently transport materials from one end to the other, ensuring the continuity and efficiency of material conveying and improving the overall working efficiency of the material conveying system.

[0018] 3. Precise positioning and installation to ensure structural stability: Marking structures are provided on the auger blades of the wear-resistant parts to secure them to designated positions. These marking structures can be either scale lines on the auger blades themselves, preventing structural instability caused by excessive installation misalignment, or spiral marking blocks fixed to the auger blades. This ensures a strong connection and structural stability between the wear-resistant parts and the auger blades, allowing the wear-resistant parts to better fulfill their wear-reducing function.

[0019] 4. Prevent materials from entering and protect connecting parts: During material conveying, the sealing plug effectively prevents material from entering the countersunk hole, thus preventing wear and corrosion of the bolts and protecting the reliability of the connection between the bolts, the indicator block, and the auger blades. This not only extends the service life of the bolts but also reduces equipment failures caused by damage to connecting components, improving the overall stability and reliability of the equipment.

[0020] 5. Prevent deformation of wear-resistant parts and maintain structural performance: The marking block has a right-angled triangular cross-section. This design provides effective support and constraint for the wear-resistant parts during the operation of the auger, preventing them from bending or deforming towards the shaft. This ensures the structural stability of the wear-resistant parts, allowing them to continuously and stably reduce wear and maintaining the overall performance stability of the improved auger blade structure.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] Example 1: This embodiment provides an improved structure for the spiral auger blade 1, such as... Figure 1 As shown: including wear-resistant parts 2 fixedly installed on the side of the spiral auger blade 1. The wear-resistant parts 2 are spirally attached to the outer wall of the spiral auger blade 1. So when conveying materials, the wear-resistant parts 2 will replace the spiral auger blade 1 as the unit with the most and strongest friction force points, thus providing protection for the spiral auger blade 1 and enhancing the service life of the spiral auger blade 1.

[0025] Preferably, the wear-resistant component 2 is a steel bar welded to the edge of the auger blade 1. From a cost perspective, steel bars are a widely used building and industrial material with ample market supply and relatively low price. During equipment improvement, there is no need to specially customize or purchase special materials; existing steel bar resources can be directly utilized, effectively reducing material procurement costs and the overall cost of equipment improvement, thus improving economic efficiency. Furthermore, the steel bar itself has high hardness, which allows it to maintain good structural integrity when facing friction and impact generated during material conveying, making it less prone to deformation or damage (at the same time, the wear-resistant component 2 can also be made of other relatively hard and wear-resistant metal structures, such as high manganese steel or hard alloy).

[0026] Furthermore, the auger blade 1 is also equipped with a marking structure, which is used to weld the reinforcing bars in a predetermined position to prevent excessive deviation between the welded reinforcing bars and their original position. Figure 1 As shown: The marking structure is the marking scale line 3 set on the spiral auger blade 1. The marking scale line 3 is also a spiral structure. The marking line makes it easy to place the reinforcing bar, so that the position of the reinforcing bar will not deviate too much.

[0027] Example 2: The difference from Embodiment 1 is that the marking structure is a marking block 4 disposed on the spiral auger blade 1, and the marking block 4 is also a spiral structure, such as... Figure 2 , 3 As shown: the marking block 4 is located inside the inner ring of the reinforcing bar. That is, when fixing the reinforcing bar, the reinforcing bar can be placed on the spiral auger blade 1 and the inner wall of the spiral auger blade 1 can be attached to the outer wall of the marking block 4, thereby saving the time of fixing the position of the reinforcing bar and improving the maintenance or assembly efficiency of the equipment.

[0028] Preferably, the marking block 4 is detachably fixed to the auger blade 1. That is, the marking block 4 can be fixed to the auger blade 1 by passing several bolts 5 through the marking block 4 and the auger blade 1. The bolts 5 also facilitate the disassembly of the marking block for maintenance.

[0029] Correspondingly, the marking block 4 is also provided with a countersunk hole 6 for the bolt 5. After the bolt 5 is fixed on the marking block 4, the end is located in the countersunk hole 6. The countersunk hole 6 is also provided with a sealing plug 7. The sealing plug 7 can be inserted into the countersunk hole 6 to seal the countersunk hole 6, thereby preventing material from entering the countersunk hole 6 during the rotation of the spiral auger blade 1.

[0030] Furthermore, the cross-section of the marker block 4 is a right-angled triangle structure, meaning that the marker block 4 has two corner sides and one inclined side. One of the two corner sides abuts against the auger blade 1, and the other corner side abuts against the wear-resistant part 2. This contact between one corner side and the wear-resistant part 2 provides stable support and positioning for the wear-resistant part 2. During material conveying, the wear-resistant part 2 is subjected to continuous friction and impact from the material. The contact between the marker block 4 and the wear-resistant part 2 effectively prevents the wear-resistant part 2 from shifting or loosening due to uneven force, thus ensuring the normal operation and service life of the wear-resistant part 2. The inclined surface on the marker block 4 also prevents material from accumulating on it and being unable to be conveyed properly.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 utility model according to the specific circumstances.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
