Description

Technical Field

[0001] This utility model belongs to the technical field of scraper material handling equipment, and in particular relates to an angled rake frame structure for material handling equipment. Background Technology

[0002] In scraper reclaimers used in pre-homogenization stockpiles, the rake's function is to loosen the material on the cross-section of the stockpile to facilitate scraping by the scraper. Conventional rake devices consist of a planar triangular frame welded from I-beams, with the rake teeth welded to the main frame; or steel wire ropes can be used as an auxiliary structure of the frame to scrape the material.

[0003] Chinese utility model patent application number 201520667465.2 discloses a material rake for a scraper reclaimer, including a rake frame and multiple rake teeth. The multiple rake teeth are arranged at intervals on the rake frame and are fixedly installed on the rake frame by bolt pairs. However, due to the variation in particle size and moisture content of the material during the production process, and the variety of material types, the angle of repose of the material varies. Therefore, the angle of the material rake needs to be frequently adjusted to adapt to different material pile angles of repose. However, the structural strength of a single rake tooth is not good. Therefore, during movement, adjustment, and use, the rake tooth is prone to bending and damage due to collisions, which affects the loosening effect of the rake frame on the material and is not conducive to improving the reliability and operating efficiency of the scraper reclaimer. Utility Model Content

[0004] In view of this, the present invention aims to propose an angled rake frame structure for a material handling device, so as to solve the problem that the structural strength of a single rake tooth in the existing angled rake frame structure is not good, which affects the loosening effect on materials.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A material handling device with an angled rake frame structure includes a lower triangular frame and an upper triangular frame. The upper triangular frame is provided with a connecting mechanism, and the lower triangular frame is provided with a rake tooth mechanism. Multiple mounting rods for mounting the rake tooth mechanism are spaced apart on the lower triangular frame. The connecting mechanism includes a connecting support and an adjusting support on the upper triangular frame. The rake tooth mechanism includes a scraper and a rake column mounted on the scraper. The length direction of the scraper is the same as the length direction of the mounting rod. A protective component is provided on the mounting rod at a position corresponding to the end of the scraper. A connecting assembly for mounting the rake column and the protective component is provided on the mounting rod.

[0007] Furthermore, the connecting assembly includes a connector and a limiting plate. At least two connectors are spaced apart along the length of the rake column. There is a fitting gap between two adjacent connectors that cooperates with the mounting rod. Each connector is detachably mounted on the limiting plate at one end and has a mounting hole that cooperates with the rake column at the other end.

[0008] Furthermore, the limiting plate is provided with a through hole that mates with the connector, and the end of the connector that passes through the through hole is provided with an anti-loosening nut.

[0009] Furthermore, a limiting block is provided at one end of the rake column that passes through the mounting hole, and the other end is connected to the scraper.

[0010] Furthermore, the lower end of the rake column protrudes beyond the lower end of the scraper.

[0011] Furthermore, positioning plates are provided at both the left and right ends of the mounting rod.

[0012] Furthermore, the protective component includes two vertical sections that can mate with the mounting holes and one inclined section, with the two vertical sections connected by the inclined section; the inclined section is inclined, with the downward-sloping end of the inclined section facing the outside of the lower tripod.

[0013] Furthermore, the vertical segment and the diagonal segment are connected by an arc-shaped segment.

[0014] Compared with the prior art, the angled rake frame structure of the material handling device described in this utility model has the following advantages:

[0015] This utility model provides an angled rake frame structure for a material handling device, which has the advantages of high structural strength, good reliability, and easy assembly and maintenance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] An angled rake frame structure for a material handling device, such as Figure 1 and Figure 2As shown, the device includes a lower tripod 1 and an upper tripod 2. The upper tripod 2 is equipped with a connecting mechanism, and the lower tripod 1 is equipped with a rake tooth mechanism. The lower tripod 1 is provided with multiple mounting rods 5 at intervals for mounting the rake tooth mechanism. The connecting mechanism includes a connecting support 3 and an adjusting support 4 provided on the upper tripod 2. The rake tooth mechanism includes a scraper 6 and a rake column 15 provided on the scraper 6. The length direction of the scraper 6 is the same as the length direction of the mounting rod 5. A protective part 7 is provided on the mounting rod 5 at the position corresponding to the end of the scraper 6. The mounting rod 5 is provided with a connecting assembly for mounting the rake column 15 and the protective part 7.

[0026] For example, both the lower triangular frame 1 and the upper triangular frame 2 can be truss structures, with a fixed connection between them. The mounting rod 5 is fixed to the lower end of the lower triangular frame 1, and the connecting support 3 and the adjusting support 4 are both fixed to the upper end of the upper triangular frame 2. In actual use, the connecting support 3 and the adjusting support 4 can be connected to the scraper reclaimer to drive this rake frame structure. Those skilled in the art can make the connections according to actual needs, which will not be elaborated here.

[0027] Preferably, the connecting assembly includes a connector 12 and a limiting plate 13. At least two connectors 12 are spaced apart along the length of the rake column 15, with a clearance between adjacent connectors 12 for engagement with the mounting rod 5. Each connector 12 is detachably mounted on the limiting plate 13 at one end and has a mounting hole at the other end for engagement with the rake column 15. For example, the limiting plate 13 has a through hole for engagement with the connector 12, and a locking nut 14 is provided at the end of the connector 12 passing through the through hole.

[0028] In practical applications, two connectors 12 are spaced apart along the rake post 15. Multiple connectors can be used if necessary to achieve multi-point limiting of the rake post 15, ensuring its stability and improving its structural strength. This embodiment uses two connectors 12 spaced apart as an example; other examples will not be elaborated upon.

[0029] By setting two connecting pieces 12 at intervals and using anti-loosening nuts 14 to limit the two connecting pieces 12, the connecting pieces 12, the limiting plate 13, and the rake column 15 can form a ring structure that cooperates with the mounting rod 5. Under the limitation of the anti-loosening nuts 14, the rake column 15 and the scraper 6 on the rake column 15 can be stably installed and fixed on the mounting rod 5. At the same time, it also makes it easier to disassemble and replace the rake column 15 and the scraper 6 on the rake column 15. The operator only needs to unscrew the anti-loosening nuts 14 to release the limiting fixation of the rake column 15, thereby realizing the disassembly of the scraper 6, which is simple to operate.

[0030] Preferably, one end of the rake column 15 passing through the mounting hole is provided with a limiting block 16, and the other end is connected to the scraper 6. For example, the limiting block 16 is fixed on the rake column 15, and multiple rake columns 15 are spaced apart along the length of the scraper 6. Each rake column 15 is fixed on the scraper 6. By connecting multiple rake columns 15 using the scraper 6, it is beneficial to improve the structural strength of the scraper 6 and the rake column 15, prevent the scraper 6 and the rake column 15 from deforming when in contact with the material, and ensure that the scraper 6 and the rake column 15 can better loosen the material.

[0031] In practical applications, the lower end of the rake column 15 protrudes beyond the lower end of the scraper 6. By protruding the rake column 15, a rake tooth structure can be formed on the scraper 6, which further improves the loosening effect of this rake frame structure on materials. Simultaneously, by setting a limiting block 16 on the rake column 15, the limiting block 16 can also effectively limit the rake column 15, ensuring that even if the anti-loosening nut 14 loosens, the rake column 15 will not separate from the connecting piece 12, thus improving the stability of the scraper 6 and the rake column 15 on the mounting rod 5. When the operator needs to disassemble the scraper 6 and the rake column 15, the scraper 6 and the rake column 15 can only be removed after completely removing the anti-loosening nut 14 and then removing the limiting plate 13. This reduces the possibility of operator error and improves the reliability and safety of this rake frame structure during use.

[0032] Preferably, positioning plates 11 are provided at both the left and right ends of the mounting rod 5. For example, two positioning plates 11 are provided at each of the left and right ends of the mounting rod 5, and each positioning plate 11 is fixed on the mounting rod 5. By setting the positioning plates 11, the ring structure formed by the limiting plate 13, the connecting piece 12, and the rake column 15 on the mounting rod 5 can play a good limiting role, preventing the above components from moving or falling off, which is conducive to further improving the reliability and safety of this rake frame structure during use.

[0033] Preferably, the protective component 7 is a U-shaped structure, comprising two vertical sections 8 that mate with mounting holes and one inclined section 9, with the two vertical sections 8 connected by the inclined section 9; the inclined section 9 is inclined, with its downward-sloping end facing outwards from the lower triangular frame 1. For example, the vertical sections 8 and the inclined section 9 are connected by an arc-shaped section 10. By providing the protective component 7 at the end of the scraper 6, when this rake frame structure first contacts the material, the protective component 7 can provide excellent buffering and protection, preventing the end of the scraper 6 from directly contacting the material. Instead, it can first press a groove into the material, and then, as the rake frame structure continues to move downwards, the scraper 6 and the rake column 15 will slowly come into contact with the material, which helps reduce the probability of bending deformation of the scraper 6 and the rake column 15.

[0034] In practical applications, by setting the inclined end of the inclined section downward toward the outside of the lower triangular frame 1, and using the arc section 10 to connect the inclined section 9 and the vertical section 8, it is not only beneficial to improve the structural strength of the protective component 7, but also to form an inclined surface and an arc surface on the surface of the protective component 7 to displace materials, which helps to reduce the probability of deformation of the protective component 7 and further improves the protective effect of the protective component 7 on the end of the scraper 6.

[0035] This utility model provides an angled rake frame structure for a material handling device, which has the advantages of high structural strength, good reliability, and easy assembly and maintenance. By adopting a double-layer structure, the overall structural strength of this angled rake frame structure is improved. At the same time, by setting protective parts at both ends of the scraper, and using the inclined and arc surfaces of the protective parts to displace material, the probability of deformation of the protective parts, scraper, and rake column is reduced, further improving the reliability and safety of this rake frame structure during use.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
