Description

Technical Field

[0001] The utility model belongs to the technical field of belt-type conveyor cleaning, and particularly relates to a polyurethane cleaning device. Background Art

[0002] Belt conveyors, such as the DZQ type coal mine belt conveyor, are a type of conveying equipment mainly used to transport materials, such as coal. Belt conveyors are mostly installed in a ring with complex terrain, and they mainly transport coal and other materials. In the process of transporting coal, due to the high humidity of coal and other reasons, a large amount of coal slime will adhere to the surface of the belt, resulting in unstable belt operation, increased motor load, uneven belt force and easy deviation.

[0003] Therefore, in actual work, operators are required to regularly clean the coal material adhering to the belt. However, due to the long conveying distance of the conveyor and the large amount of damp coal material adhering to the belt, the manual cleaning workload is large and there are safety hazards.

[0004] Therefore, in order to clean the coal adhering to the belt, the current common practice is to install a scraper on the belt conveyor. During the conveying process of the belt conveyor, the belt and the scraper rub against each other to remove the adhering coal.

[0005] However, the scraper currently used cannot be in contact with the belt of the conveyor belt during use. If it is too tight, it will easily damage the belt, but the disadvantage is that the scraping is not sufficient. Secondly, as the scraper wears more, the gap between it and the belt gradually increases, resulting in a gradual increase in the amount of residual coal. At the same time, during the scraping process, the scraper cannot avoid the thick coal, resulting in the thick coal being stuck under the scraper during the conveyor belt transmission, and forming a large resistance, causing the conveyor belt on the conveyor belt to jam. In severe cases, the scraper or belt may break. Utility Model Content

[0006] Based on the above background, the purpose of the utility model is to provide a polyurethane sweeper device.

[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0036] Example 1

[0037] like Figure 1 As shown, a polyurethane sweeper device includes a mounting frame 2 (the mounting frame 2 is cylindrical), and a polyurethane scraper 3 is mounted and connected to the mounting frame 2. The polyurethane scraper 3 is integrally formed with an arc-shaped convex portion 31 that is protruding; during the scraping process, the arc-shaped convex portion 31 acts on the coal material adhered to the belt, and the arc-shaped convex portion 31 of the arc structure is used to increase the scraping effect of the polyurethane scraper 3 and reduce the wear. Specifically, during the scraping process, the shape structure of the arc-shaped convex portion 31 can prevent the scraper from being stuck by the thick coal material during the scraping process.

[0038] At the same time, the polyurethane sweeper device also includes a spring buffer reset mechanism assembled and connected on both sides of the mounting frame 2. The spring buffer reset mechanism is used to form a flipping buffer when the thickness of the coal seam is relatively large during the scraping process. After scraping a part of the coal, it is slightly flipped to allow the coal to pass through, which is convenient for subsequent scraping and removal. This method avoids the jamming between the polyurethane scraper 3 and the coal and belt when the thickness of the coal is large, and avoids damage to the belt due to forced scraping.

[0039] The details are as follows: the spring buffer reset mechanism includes a mounting seat 1 rotatably connected to the mounting frame 2 (the mounting seat 1 is shaped as follows: the mounting seat 1 includes a longitudinal plate portion slidably connected to the mounting frame 2, and a horizontal mounting plate portion is integrally formed on the longitudinal plate portion; the horizontal mounting plate portion is installed on the frame of the belt conveyor), the spring buffer reset mechanism also includes a swing arm plate 5, and the lower end of the mounting seat 1 is fixedly assembled and connected with a connecting piece.

[0040] Specifically, the upper end of the swing arm plate 5 is integrally formed with a sleeve portion 51 sleeved on the mounting frame 2 (the sleeve portion 51 is fastened to the mounting frame 2 through a bolt structure). At the same time, the connecting member includes a connecting screw 8 fixedly assembled at the lower end of the mounting seat 1, and a fastening nut is threadedly connected to the connecting screw 8.

[0041] An adjusting screw 10 is fixedly connected to the connecting piece on the connecting screw 8 (the fixing method is: a pipe sleeve 6 is threadedly connected to the connecting screw 8, the adjusting screw 10 is welded to the pipe sleeve 6, and the adjusting screw 10 is vertically welded to the pipe sleeve 6).

[0042] The swing arm plate 5 is provided with an adjustment through hole adapted to the adjustment screw 10 , and the adjustment screw 10 passes through the adjustment through hole; and because the adjustment through hole has a certain width, the adjustment screw 10 can slide relative to the adjustment through hole.

[0043] At the same time, a spring 7 is sleeved on the adjusting screw 10, and a mounting nut is threadedly connected to the adjusting screw 10 (the two ends of the spring 7 are respectively pressed against the swing arm plate 5 and the mounting nut), and the adjusting screw 10 is fixedly assembled on the frame of the belt conveyor.

[0044] During the working process, when the polyurethane scraper 3 scrapes against the thick adhered coal material, the polyurethane scraper 3 carries the swing arm plate 5 fixed on the mounting frame 2 to rotate. During the rotation of the swing arm plate 5, the swing arm plate 5 contacts the spring 7. In this process, the adjusting screw 10 slides relatively in the adjusting through hole on the swing arm plate 5.

[0045] In this process, the spring 7 is used to buffer the polyurethane scraper 3, so that the polyurethane scraper 3 can be properly turned over when encountering thick and adhered coal, so as to avoid the thick coal and prevent the polyurethane scraper 3 from being stuck by the coal.

[0046] At the same time, when the belt conveyor continues to transmit, under the elastic restoring force of the spring 7, the mounting frame 2 and the swing arm plate 5 are reset.

[0047] The above method can be used to scrape the coal adhered to the belt in a protective manner, and the above method can promote the polyurethane scraper 3 to swing and flip according to the thickness of the coal, which greatly reduces the excessive wear of the polyurethane scraper 3. At the same time, because the polyurethane scraper 3 can flip, it can scrape the coal without getting stuck.

[0048] The two ends of the mounting frame 2 are respectively sleeved with a spacer 9 for separating the mounting seat 1 and the sleeve portion 51; the spacer 9 is located between the mounting seat 1 and the sleeve portion 51. The material of the spacer 9 is polyurethane.

[0049] Example 2

[0050] like Figure 1 As shown, based on the structure of Example 1, this embodiment has a rectangular mounting opening at the bottom of the polyurethane scraper 3, and a strip boss 21 is integrally formed on the mounting frame 2 and plugged into the rectangular mounting opening; correspondingly, the lower end of the polyurethane scraper 3 is threadedly connected with a plurality of fastening bolts 4 fastened to the strip boss 21.

[0051] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
