Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] As Figure 1As shown in the figure, the utility model provides an adjustable belt scraper cleaner, which is installed under the head of the conveyor belt. It includes: a scraper cleaning assembly 1, which is arranged under the head of the conveyor belt, and a triangular coal scraping plate 11 is provided at the top of the scraper cleaning assembly 1 to fit with the lower surface of the conveyor belt; a guiding and anti-sway assembly 2, which is arranged on the left and right sides of the scraper cleaning assembly 1, and the guiding and anti-sway assembly 2 has a U-shaped vertical card slot 21 to cooperate with the left and right sides of the scraper cleaning assembly 1; a skeleton fixing assembly 3, which is arranged between the head of the conveyor belt and the guiding and anti-sway assembly 2; and an adjustment bracket assembly 4, which is arranged under the scraper cleaning assembly 1 and adjusts the height of the scraper cleaning assembly 1.

[0037] In order to clean the materials adhered to the surface of the conveyor belt and prevent the belt from running off track, as Figure 2 shown, in an embodiment of the adjustable belt scraper cleaner provided by the utility model, the scraper cleaning assembly 1 includes: a triangular coal scraping plate 11, which is arranged along the width direction of the conveyor belt, and the triangular coal scraping plate 11 is in a roof-shaped structure; a U-shaped polyurethane support seat 12, which is arranged under the triangular coal scraping plate 11; and a reinforcing rib 13, which is horizontally arranged at the middle position of the U-shaped polyurethane support seat 12.

[0038] As Figure 3 and Figure 4 shown, in an embodiment of the adjustable belt scraper cleaner provided by the utility model, in order to ensure that the scraper cleaning assembly does not swing when moving up and down, the guiding and anti-sway assembly 2 includes: a U-shaped vertical card slot 21; a first connecting lug 22, which is arranged above the U-shaped vertical card slot 21, and a first screw hole 23 is arranged on the first connecting lug 22; in order to make the overall connection firm, the skeleton fixing assembly 3 includes: a horizontal overlapping cross plate 31, a second connecting lug 32 is arranged at one side edge of the horizontal overlapping cross plate 31, and a second screw hole 33 is arranged on the second connecting lug 32, and a bolt passes through the first screw hole 23 and the second screw hole 33 to connect the guiding and anti-sway assembly 2 and the skeleton fixing assembly 3; a J-shaped fixing frame 34, whose top end is fixed to the horizontal overlapping cross plate 31, and a fastening hook is arranged below and is fixed to the head of the conveyor belt through a tensioning screw 35.

[0039] In order to ensure that the scraper cleaning assembly is closely attached to the conveyor belt and clean the materials on the conveyor belt, as Figure 5As shown, in an embodiment of the adjustable belt scraper cleaner provided by the present utility model, the adjustment bracket assembly 4 includes: a scraper clamping seat 41, which has a receiving groove above for placing the scraper cleaning assembly 1. Adjusting screw holes 14 are provided on both the U-shaped polyurethane support seat 12 and the scraper clamping seat. Adjusting screw holes are also formed at the left and right edge positions of the scraper clamping seat 41; an adjusting screw 42, on which a tension spring 43 is sleeved and the top end of which passes through the adjusting screw hole 14 to fix the scraper clamping seat 41 and the scraper cleaning assembly 1; an adjusting lead screw 44, which passes through the adjusting screw hole to be connected with the scraper clamping seat 41, and the upper end of the adjusting lead screw 45 is connected with the horizontal overlapping cross plate 31 through a lead screw cap seat 36 and a guide sleeve 37.

[0040] When the installer installs the device under the head of the conveyor belt according to the design requirements, the triangular coal scraping plate of the scraper cleaning assembly fits with the material-carrying surface of the conveyor belt. When the conveyor belt starts to run, the triangular coal scraping plate of the scraper cleaning assembly scrapes the materials carried on the belt from the fast-running belt, and through the U-shaped polyurethane support seat, it falls into the tail of the previous conveyor belt or the coal mine through the U-shaped slot of the guiding and anti-swaying assembly. As the triangular coal scraping plate of the scraper cleaning assembly is gradually worn during the fast running of the conveyor belt, the tension spring of the adjustment bracket assembly moves the triangular coal scraping plate upward from the U-shaped slot of the guiding and anti-swaying assembly through an adjusting nut, an adjusting lead screw, etc., to ensure that the triangular coal scraping plate of the scraper cleaning assembly fits with the material-carrying surface of the conveyor belt. In this way, the running belt is cleaned and scraped in a cycle to ensure that the surface of the conveyor belt is clean.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
