Description

Technical field:

[0001] The utility model belongs to the field of mechanical processing, in particular to a feeding device of a back scraper. Background technology:

[0002] Power angle steel towers are a common structure in power transmission networks, constructed from a combination of several angle steels. For assembly purposes, the angle steels require both root-cutting and back-scaling during production. Root-cutting refers to machining the inner corners of the angle steel, while back-scaling refers to machining the outer corners. Angle steel requiring both root-cutting and back-scaling is primarily used to connect the main angle steel of adjacent tower sections, as well as for diagonal steel that requires interruption and for cross-sectioning of the main steel. Root-cutting facilitates the outer angle steel to fit the outer side of the main steel, while back-scaling facilitates the inner angle steel to fit the inner side of the main steel.

[0003] The angle steel back-shoveling machine is mainly used for the process of angle steel back-shoveling. However, the original feeding frame of the back-shoveling machine is basically located inside the machine body and the outer edge is relatively short. There is no extended feeding structure on the outside of the machine. When the angle steel is back-shoveled, it is necessary to manually hold the angle steel piece and feed it into the feeding port of the back-shoveling machine, resulting in high workload for on-site workers and long processing time. Moreover, manually holding the angle steel piece cannot ensure that it can enter the back-shoveling machine horizontally. The angle steel piece is easy to warp, which ultimately leads to poor milling effect of angle steel back-shoveling and low processing efficiency. Utility model content:

[0004] The purpose of the utility model is to provide a feeding device for a back scraping machine, and to overcome the deficiencies of the above-mentioned prior art, thereby effectively solving the existing problem of low efficiency in angle steel back scraping processing.

[0005] The content of the utility model: A shovel back feeding device includes a support plate, a pair of vertical plates are vertically installed on the top wall of the support plate along the length direction, a plurality of rollers are evenly connected to the top of the vertical plates in a rotating manner along the length direction, and a bracket is installed on the bottom wall of the support plate.

[0006] Furthermore, a plurality of semicircular brackets are evenly opened along the length direction on the top of the vertical plate, and the roller shafts of the rollers are matched and placed in the semicircular brackets, and the roller shafts of the rollers are rotatably connected to the semicircular brackets.

[0007] Furthermore, a semicircular card is coaxially mounted on the inner circumference of the semicircular bracket. The semicircular card is located at the outer end of the semicircular bracket. The semicircular card is used to prevent the roller from being displaced during rotation.

[0008] Furthermore, bolt connection pieces are vertically installed at both ends of the support plate.

[0009] Furthermore, chamfers are provided on the circumferential surfaces at both ends of the roller.

[0010] The beneficial effects of the utility model are as follows: by uniformly rotating a number of rollers connected at the top of the vertical plate, the angle steel to be processed with back scraping can be supported and transported, which not only reduces the work intensity and shortens the processing time, but also ensures the milling effect of the back scraping of the angle steel piece and improves the processing efficiency.

[0016] In the figure, 1 is a support plate, 2 is a vertical plate, 3 is a roller, 4 is a bracket, 5 is a semicircular bracket, 6 is a semicircular card, 7 is a bolt connecting piece, and 8 is an angle steel. Specific implementation method:

[0017] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings:

[0018] like Figures 1 to 5 As shown, a shovel back feeding device includes a support plate 1, a pair of vertical plates 2 are vertically installed on the top wall of the support plate 1 along the length direction, a number of rollers 3 are evenly connected to the top of the vertical plate 2 in the length direction, a bracket 4 is installed on the bottom wall of the support plate 1, a number of semicircular brackets 5 are evenly opened on the top of the vertical plate 2 along the length direction, the roller shafts of the rollers 3 are matched and placed in the semicircular brackets 5, the roller shafts of the rollers 3 are rotatably connected to the semicircular brackets 5, a semicircular card 6 is coaxially installed on the inner circumferential surface of the semicircular bracket 5, the semicircular card 6 is located at the outer end of the semicircular bracket 5, the semicircular card 6 is used to prevent the roller 3 from being displaced during rotation, bolt connecting plates 7 are vertically installed at both ends of the support plate 1, and chamfers are opened on the circumferential surfaces of both ends of the roller 3.

[0019] Specifically, the angle steel 8 to be processed and scraped back can be supported and transported by a plurality of rollers 3 connected and rotated evenly on the top of the vertical plate 2.

[0020] In actual use, first place the feeding device at the feeding port of the back-shoveling machine, and align the feeding device with the feeding rack of the back-shoveling machine. At this time, the angle steel 8 to be processed is placed upside down on the feeding line formed by several rollers 3. When the angle steel 8 is pushed, the roller 3 can smoothly feed the angle steel 8 into the back-shoveling machine; the roller shaft of the roller 3 is matched and placed in the semicircular bracket 5, so that the roller 3 can be quickly assembled or disassembled with the vertical plate 2; the semicircular card 6 can limit the left and right displacement of the roller 3 during the rotation process, thereby avoiding the bracket The two side walls of the roller 3 rub against the inner wall of the vertical plate 2, making the rotation of the roller 3 more stable and smooth; chamfers are provided on the circumferential surfaces at both ends of the roller 3, so that the two ends of the roller 3 fit more closely with the inner wall of the angle steel 8, increasing the friction between the two components and facilitating the rapid transportation of the angle steel 8; several groups of feeding devices can be placed in a straight line, and the bolt connecting pieces 7 in the two adjacent groups of feeding devices can be aligned and connected and fixed with bolts, thereby lengthening the conveying line of the feeding device and increasing the conveying capacity of the angle steel 8.

[0021] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
