Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor cleaning, in particular to a rhombus bidirectional running belt conveyor empty section cleaning device. Background Art

[0002] Belt conveyors, also known as belt conveyor belts, are widely used in the transportation of ports and coal mines. In the process of conveying materials on belt conveyors, the empty section cleaner is mainly used to clean the residue on the return belt of the belt conveyor. It is generally installed on the non-bearing surface of the return belt at the front end of the belt conveyor's tensioning device and the front end of the tail roller to prevent the residue from entering the tensioning device roller and the tail roller and the belt, causing damage to the roller's rubber surface and the belt. There are two structures of cleaners commonly used for empty section belt cleaning. One is a V-type cleaner. The V-type cleaner can only be used for one-way running belt conveyors. When the belt conveyor runs in the reverse direction, due to the structural characteristics of the V-type cleaner, material will accumulate inside, and there is a risk of scratching the belt; the other is an empty section one-line cleaner. Although this type of cleaner can be used to clean bidirectional running belts, this type of cleaner has the following shortcomings:

[0003] 1) Large vibration: Due to design and manufacturing reasons, the air section sweeper will produce large vibration during use, affecting the stability of the equipment, and may also cause noise and wear;

[0004] 2) The contact with the belt is not tight: If the contact between the cleaner and the belt is not tight enough, the cleaning effect may be poor, and the residual material may still damage the conveyor belt and rollers;

[0005] 3) The spring compensation mechanism has a small compensation amount: when the position of the conveyor belt changes, the cleaner may not be able to adjust its position in time to maintain good contact, affecting the cleaning effect;

[0006] 4) Regular adjustment is required: In order to maintain a good cleaning effect, the empty section sweeper may need to be adjusted regularly, increasing the complexity and frequency of the containment work. Utility Model Content

[0007] The embodiment of the utility model provides a rhombus-shaped bidirectional belt conveyor empty section cleaning device, so as to achieve the technical effect of being suitable for cleaning the empty section of a bidirectional belt and having a good fitting effect with the belt.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the implementation mode and the accompanying drawings. Here, the schematic implementation mode of the utility model and its description are used to explain the utility model, but are not used as a limitation of the utility model.

[0025] like Figures 1 to 5 As shown, a rhombus-shaped bidirectional belt conveyor empty section cleaning device is composed of a cleaning device frame 1 and a cleaning plate 2. The cleaning device frame 1 is composed of a rhombus-shaped inner frame 101 and an outer pressure plate 102.

[0026] The left and right vertex corners of the diamond-shaped inner frame 101 are respectively configured to be arc-shaped structures, which can effectively avoid scratching the belt surface during the belt cleaning process.

[0027] The cleaning plate 2 is arranged along the outer wall of the diamond-shaped inner frame 101, and then pressed by the outer pressing plate 102 on the outside of the cleaning plate 2. Specifically, the diamond-shaped inner frame 101, the cleaning plate 2 and the outer pressing plate 102 are respectively provided with fixing holes 10, and the fixing holes 10 of the three are arranged correspondingly, and the diamond-shaped inner frame 101, the cleaning plate 2 and the outer pressing plate 102 are locked and fixed by the bolt assembly 9 penetrating the fixing holes 10.

[0028] In this embodiment, the cleaning plate 2 is made of polyurethane rubber plate. The cleaning plate 2 can be provided on each side of the outer wall of the diamond-shaped inner frame 101 , and each cleaning plate 2 corresponds to an outer pressure plate 102 .

[0029] The interior of the diamond-shaped inner frame 101 is connected to the belt conveyor roller beam 3 through the hanger 4. Specifically, the hanger 4 is composed of a fixed beam 1 401, a hanger 403 and a fixed beam 2 402. The fixed beam 401 is placed between two belt conveyor roller beams 3, and the two ends of the fixed beam 1 401 are respectively fixedly connected to the belt conveyor roller beams 3 at their corresponding ends.

[0030] A fixed beam 402 is disposed between adjacent sides of the left and right vertices (arc-shaped structures) of the diamond-shaped inner frame 101. Both ends of each fixed beam 402 are fixedly connected to the diamond-shaped inner frame 101, respectively, to ensure that the fixed beam 1 401 and the fixed beam 2 402 are disposed in parallel.

[0031] The fixed crossbeam 1 401 and the fixed crossbeam 2 402 on the same side are connected by two suspension rods 403. The fixed crossbeam 1 401 is provided with a fixed ear plate 6 at the upper end of each suspension rod 403, and the same suspension rod 403 is provided with two fixed ear plates 6, and a certain distance is set between the two fixed ear plates 6. The upper end of the suspension rod 403 is placed between the two fixed ear plates 6 and is hinged to them through a positioning pin 11.

[0032] A fixed ear plate 27 is provided at the lower end of each suspension rod 403 corresponding to the fixed cross beam 2 402, and two fixed ear plates 27 are provided corresponding to one suspension rod 403. A certain distance is also provided between the two fixed ear plates 27, and a long hole 8 is obliquely opened on each fixed ear plate 27. Pins 12 matching the long holes 8 are provided on both sides of the lower end of the suspension rod 403, and the lower end of the suspension rod 403 is slidably connected with the fixed ear plate 27 through the cooperation of the pins 12 and the long holes 8.

[0033] This device is installed in the position where the belt conveyor is prone to carry materials in the empty return section, so as to facilitate the cleaning of the return materials of the belt conveyor. When the cleaning plate 2 in this device is newly installed, its bottom is in contact with the surface of the belt 5, and the lower end pin 12 of the suspension rod 403 is placed at the bottom end of the long hole 8. As the lower end of the cleaning plate 2 gradually wears, the pin 12 at the lower end of the suspension rod 403 gradually moves upward along the long hole 8 until the pin 12 moves to the uppermost end of the long hole 8. Under the action of the four suspension rods 403, the sweeper frame 1 is in a fixed state, preventing the cleaning plate 2 from being damaged due to severe wear and failure to replace it in time. At this time, the cleaning plate 2 with severe wear is replaced.

[0034] The utility model has few moving parts. During installation and maintenance, cleaning plates are respectively installed at the left and right ends of the device, which can be suitable for belts running in both directions and has an automatic compensation function after the cleaning plates are worn. When the cleaning plates are worn, the hanging bracket allows the cleaning plates to have a certain range of movement, and the overall gravity of the device is relied upon to make the cleaning plates and the belt fully fit together to achieve automatic compensation.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
