[0013] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.
[0014] See Figure 1 This embodiment discloses an adjustable belt self-cleaning device, including a brush body 1 located below the belt of a belt conveyor. The brush body 1 can be a plate brush. The brush body 1 is detachably installed in a trough 2. The left and right ends of the trough 2 are respectively mounted on two fixed frames 4 via rocker arms 3. The two fixed frames 4 are respectively mounted on the frame of the belt conveyor. The middle section of the rocker arm 3 is bent to form a bent arm. The middle section of the rocker arm 3 is rotatably mounted on the fixed frame 4 via a hinge shaft 5. The fixed frame 4 has an arc-shaped waist groove 6 concentric with the hinge shaft 5. One end of the rocker arm 3 has a first through hole 7. A first screw 8 passes through the first through hole 7 of the rocker arm 3 and the arc-shaped groove 6 of the fixing frame 4 in sequence and is tightened with a first nut to achieve a locking installation between one end of the rocker arm 3 and the fixing frame 4. The other end of the rocker arm 3 is rotatably connected to the end of the groove 2 and can be locked. A hinge piece 9 is fixed to the end of the groove 2. The hinge piece 9 can be fixed to the end of the groove 2 by screw connection. A second screw 10 passes through the end of the rocker arm 3 and the hinge piece 9 in sequence and is tightened with a second nut to achieve a locking installation between the end of the rocker arm 3 and the hinge piece 9.
[0015] The groove 2 has an installation groove that extends in the left and right direction and runs through the left and right sides. The base 11 of the brush body 1 is slidably set in the installation groove of the groove 2, and is screwed into the threaded holes on the side wall of the groove 2 by multiple fastening screws 12 on the front and rear sides and pressed against the base 11 of the brush body 1, so as to realize the detachable installation of the brush body 1 and the groove 2.
[0016] The fixed frame 4 is a three-section bent plate consisting of an upper vertical plate, a horizontal plate and a lower vertical plate. The arc-shaped waist groove 6 is opened on the lower vertical plate. Two vertically extending waist-shaped holes 13 are opened on the upper vertical plate. Two mounting screws are passed through the two waist-shaped holes 13 and tightened on the frame of the belt conveyor to realize the installation of the fixed frame 4 and the frame.
[0017] Among them, the first screw 8, the second screw 10, and the hinge shaft 5 all extend axially in the left-right direction, while the fastening screw 12 extends axially in the front-back direction.
[0018] When the belt conveyor is working, the brush body 1 automatically cleans the surface of the running belt, so that the soot and other adhering substances on the belt surface are cleaned to the material collection tray of the equipment, thus realizing the automatic cleaning operation of the belt surface.
[0019] When adjusting the height of the brush body 1, first loosen the first nut to allow the first screw 8 to slide freely in the arc-shaped groove 6. At this time, the rocker arm 3 can rotate around the hinge shaft 5. By rotating the rocker arm 3, the height of the groove 2 mounted on the other end of the rocker arm 3 can be adjusted, thus adjusting the height of the brush body 1 mounted on the groove 2. After adjustment, tighten the first nut to lock the position of the rocker arm 3. If the angle of the brush body 1 changes after adjustment, loosen the second nut to adjust the angle between the hinge plate 9 and the rocker arm 3 until the brush body 1 is horizontal, then tighten the second nut. This ensures that the bristles of the brush body 1 are in close contact with the belt surface, guaranteeing its cleaning effect.
[0020] When the bristles of the brush body 1 are worn to a certain extent and need to be replaced, first loosen the first nut. Under the action of gravity of the groove 2 and the brush body 1, the rocker arm 3 will automatically rotate around the hinge shaft 5, causing the groove 2 and the brush body 1 to move downward. At this time, by loosening the fastening screws 12 on the front and rear sides of the groove 2, the brush body 1 can be slid out along the opening end of the mounting slot of the groove 2. Then, a new brush body 1 can be installed, and then the fastening screws 12 can be tightened to achieve convenient replacement of the brush body 1.
[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
