Description

Technical Field

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

[0002] During operation, the non-working surface of a conveyor belt often becomes clogged with dust or a small amount of material from the upper layer, which is carried to the tail of the conveyor. To prevent material and dust from becoming trapped between the tail pulley and the belt, a cleaning device is often installed. Existing non-working surface cleaning devices for conveyors typically employ either spring-loaded or chain-loaded mechanisms. The belt vibrates during operation, and after prolonged use, the springs accumulate dust and become deformed, potentially permanently deformed. This loss of automatic adjustment prevents the cleaning device from functioning properly, rendering it unable to clean accumulated dust and residual material from the non-working surface. Prolonged periods of neglect can reduce friction between the belt and the tail pulley, causing the tail pulley to slip and the belt to wear, shortening the belt's service life. Utility Model Content

[0040] like Figure 1-4 As shown, the belt conveyor cleaning device 200 includes a mounting frame 210, a cleaning member 220 and a support and adjustment mechanism 230.

[0041] The mounting bracket 210 is V-shaped.

[0042] Cleaning member 220 is used to elastically contact belt 300 to clean dust and materials from the non-working surface of the belt. Preferably, cleaning member 220 is a polyurethane plate. Cleaning member 220 is mounted on mounting frame 210. Specifically, cleaning member 220 is symmetrically mounted on the V-shaped mounting frame.

[0043] The cleaning member 220 is assembled and connected to the mounting frame 210. Specifically, the cleaning member 220 and the mounting frame 210 are provided with corresponding connecting holes, and connecting members 222 are provided in the connecting holes to achieve the assembly connection between the cleaning member 220 and the mounting frame 210. The connecting members 222 are preferably bolts and nuts.

[0044] In one embodiment, a lining plate 221 is provided on the outside of the cleaning member 220 , and a connection hole corresponding to the cleaning member 220 is provided on the lining plate 221 .

[0045] This utility model uses polyurethane sheets, which are 3 to 5 times more wear-resistant than conventional rubber, as cleaning plates. These are symmetrically arranged on either side of the V-shaped frame. The cleaning plates are equipped with mounting holes for assembly with the V-shaped frame. The bottom edge of the cleaning plates extends 12mm beyond the V-shaped frame, ensuring flexible contact with the belt and extending the belt's service life.

[0046] The support adjustment mechanism 230 is provided on the mounting frame 210 and is used to set the mounting frame on the housing of the belt conveyor and adjust the gap between the cleaning member and the belt. In one embodiment, the support adjustment mechanism 230 includes a support screw assembly 231 and an adjustment plate assembly 232.

[0047] Mounting bracket 210 is mounted with a support screw assembly 231. Specifically, support screw assembly 231 includes a first support screw 2311 and a second support screw 2312. The first and second support screws 2311 and 2312 are located in the same plane and are arranged parallel to each other. They are positioned one behind the other along the material conveying direction. The first and second support screws are M14 screws.

[0048] Adjustment plate assemblies 232 are mounted at each end of the support screw assembly 231. These are used to seal the belt conveyor housing and adjust the support screw assembly's mounting height on the conveyor housing. Specifically, the adjustment plate assembly 232 comprises a first L-shaped adjustment plate 2321 and a second L-shaped adjustment plate 2322. Both the first and second L-shaped adjustment plates 2321 and 2322 have identical structures, consisting of a vertical portion and a horizontal portion. Connection holes are machined in the vertical portion, while the horizontal portion also has connection holes.
