[0020] The present invention will be further described in detail below with reference to the accompanying drawings: This embodiment is implemented based on the technical solution of the present invention and provides detailed implementation methods, but the protection scope of the present invention is not limited to the following embodiments.
[0021] Example 1: As Figures 1-4 As shown in this embodiment, an automatic debris cleaning device for the unloading point of a belt conveyor includes a grate, a roller, a toothed crown, a discharge chute, a cycloidal reducer, and a bearing housing.
[0022] The belt conveyor has a discharge chute at its discharge point. The top of the discharge chute is beveled and a grate is welded to it. A roller is mounted on the upper central axis of the discharge chute, with bearing housings bolted to a bracket. The roller's sides are fixed to the bearing housings. A cycloidal reducer is mounted on one side of the roller, with its output shaft connected to the roller. Evenly spaced toothed crowns are mounted on the roller, rotating to insert into the gaps between the grate. The roller, bearing housings, and cycloidal reducer are all mounted together in the middle position above the grate.
[0023] This utility model discloses an automatic debris cleaning device at the discharge point of a belt conveyor, wherein the grate is inclined at 30°. A 30° angle discharge chute is fabricated and welded to the grate made of round steel at the same angle. The 30° inclination of the grate facilitates the cleaning of mineral powder lumps, debris, etc., and the angle allows for natural sliding, preventing the mineral powder lumps and debris from being unable to be cleared from the grate during the operation of the toothed crown.
[0024] This utility model relates to an automatic debris cleaning device at the discharge point of a belt conveyor, wherein each gap in the grate is 80mm wide. When the roller is running, it drives the toothed crown to rotate. The toothed crown rotates into the grate and then rotates out of the grate, so the gap width of the grate is greater than the size of the toothed crown.
[0025] This utility model discloses an automatic debris cleaning device at the unloading point of a belt conveyor, wherein the distance between two adjacent teeth on the roller is 80mm. The size of the distance between adjacent teeth needs to be matched with the size of the adjacent grates.
[0026] This utility model relates to an automatic debris cleaning device at the discharge point of a belt conveyor. The toothed crown protrudes 3cm into the lowest point of the grate. Because the discharge end of the grate has horizontal ribs, there is obstruction when cleaning mineral powder lumps and debris. Therefore, protruding the toothed crown 3cm into the grate and operating the toothed crown during discharge from the grate results in better cleaning of mineral powder lumps and debris.
[0027] This utility model relates to an automatic debris cleaning device at the unloading point of a belt conveyor, wherein the rotation direction of the roller is opposite to the movement direction of the conveyor belt.
[0028] This utility model relates to an automatic debris cleaning device at the unloading point of a belt conveyor. The three toothed crowns form a group, and three groups of toothed crowns are set on the roller. The three groups of toothed crowns are respectively set at the 0° angle straight position, the 120° angle straight position and the 240° angle straight position on the roller. The three groups of toothed crowns are fixed on the roller in a spiral state.
[0029] This utility model relates to an automatic debris cleaning device at the unloading point of a belt conveyor. When the top of the tooth crown is vertically upward, the vertical distance between the top of the tooth crown and the conveyor belt of the belt conveyor is 200mm.
[0030] Example 2: Figures 1-4 As shown in the figure, this embodiment relates to an automatic debris cleaning device at the unloading point of a belt conveyor. Figure 2 The middle arrow indicates the direction of material transport on the belt conveyor; the control box and operation buttons are not shown in the attached diagram, as they are existing technology. Following the principle of ease of operation and convenient installation, the specific installation steps are as follows:
[0031] 1. Construct a 30° angle feeding chute and weld it to the grate made of round steel at the same angle.
[0032] 2. As shown in position 4, install three sets of tooth crowns evenly on the roller. The roller, bearing housing, and cycloidal reducer are installed together in the middle position above the grate.
[0033] 3. First, reverse the height of the grate by 50mm from the lowest point and insert the top of the tooth crown 3cm deep. Then, keep the top of the tooth crown 200mm away from the conveyor belt. Finally, fix the height of the roller.
[0034] 4. After determining the height and center line of the roller and grate, install the bearing base for fixation.
[0035] 5. Install the control box at a convenient operating location on the side of the material chute.
[0036] Installation requirements: The width of each gap in the grate is 80mm; the center distance between two adjacent teeth on the roller is also 80mm; the roller rotates in the opposite direction to the conveyor belt.
[0037] The components are connected as follows: the grate is fixed to the feed chute at a 30° angle by welding; the bearing seat is fixed to the bracket by bolts; the roller is fixed to the bearing seat; the tooth crown is welded to the roller; and the cycloidal reducer is installed on one side of the roller shaft and fixed thereto.
[0038] In operation, the automatic cleaning device is turned on, the mechanical movement of the cycloid speed reducer drives the roller, the roller drives the gear crown to move, the loose part of the mixed ore is introduced to pass through the grate into the discharging chute, and is supplied to the sintering machine through the belt machine, the sundries and the iron ore powder lumps filtered out by the grate are cleaned out by the gear crown driven by the rotating roller, and are centrally treated.
[0039] The above merely provides the preferred embodiments of the present application, and these embodiments are different implementation manners based on the overall concept of the present application, and the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
