[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0022] See also Figures 1-4 The utility model provides the following technical solutions: a sweeper, including a mounting bracket 1, a No. 2 fixed pulley 18 is fixedly mounted around the top of the mounting bracket 1, a transmission bearing 17 is rotatably mounted inside the No. 2 fixed pulley 18, a No. 1 roller 21 is fixedly mounted on the surface of the transmission bearing 17, a support frame 3 is fixedly mounted on one side of the mounting bracket 1, a No. 2 motor 10 is fixedly mounted on the top of the support frame 3, a reduction motor 9 is fixedly mounted on the No. 2 motor 10 through the rotating shaft at the output end, the reduction motor 9 is fixedly mounted on the No. 2 transmission bearing through the rotating shaft at the output end, a No. 2 roller is fixedly mounted on the surface of the No. 2 transmission bearing, a conveyor belt 8 is connected to the surface of the No. 1 roller 21 and the No. 2 roller in transmission connection, a No. 1 motor 4 is fixedly mounted on the top below the mounting bracket 1, and a No. 1 pulley 5 is fixedly mounted on the No. 1 motor 4 through the rotating shaft at the output end;
[0023] On the front and rear sides to the right of the installation bracket 1, a first fixed pulley 14 is fixedly installed. Inside the first fixed pulley 14, a sweeper bearing 22 is rotatably installed. At one end of the sweeper bearing 22, a second pulley 7 is fixedly installed. A transmission belt 6 is drivingly connected between the surfaces of the second pulley 7 and the first pulley 5. On the surface of the sweeper bearing 22, a U-shaped plate 25 is fixedly installed. And there are multiple U-shaped plates 25, and the U-shaped plates 25 are arranged in a circumferential pattern on the surface of the sweeper bearing 22. An installation bolt 24 is threadedly installed inside the U-shaped plate 25, and a composite rubber strip 23 is fixedly installed on the surface of the installation bolt 24.
[0024] First, the second motor 10 drives the first drum 21 and the conveyor belt 8 to rotate, starting the belt conveyor to transport materials. At the same time, the first motor 4 is also started to drive the first pulley 5, the transmission belt 6 and the second pulley 7 to rotate. The second pulley 7 drives the sweeper bearing 22 to rotate, so that the composite rubber strip 23 on the surface of the sweeper bearing 22 cleans the residual materials on the surface of the conveyor belt 8. And the sweeper adopts the reverse rolling mode of the composite rubber strip 23 to effectively clean the residual materials on the surface of the conveyor belt 8, ensuring good contact between the composite rubber strip 23 and the conveyor belt 8. While improving the operating efficiency of the belt conveyor, it reduces the equipment failure rate and maintenance cost. The setting of the reduction motor enables the transmission ratio of the reducer to be well controlled, reducing the power of the second motor 10 to meet the torque required for the operation of the conveyor belt 8. This can reduce the operating load of the second motor 10 and extend its service life. At the same time, it also helps to reduce the operating cost of the conveyor. Since the mounting partition 20 is fixedly installed on one side of the mounting bracket 1, it can effectively prevent materials from falling from both sides of the conveyor belt 8, so that there will be no accumulation of mud, stone powder on both sides of the conveyor, greatly reducing the cleaning cost. Since the movable plates 12 are movably installed on both sides of the mounting partition 20, and the discharge plate 11 is fixedly installed on one side of the movable plate 12, the angle of the discharge plate 11 can be adjusted through the movable plate, so that the angle of the conveyor when discharging can be controlled, facilitating discharging on the ground with different height differences. Since the first fixed pulley 14 is slidably connected to the chute 13, by unscrewing the hexagon bolt above the first fixed pulley 14, the first fixed pulley 14 can slide on the surface of the first fixed pulley 14, so that the position of the sweeper can be adjusted to facilitate the sweeper to better clean the residual materials on the surface of the conveyor belt 8. And the cleaned materials can be caught by the waste box 19 under the sweeper, avoiding the cleaning cost caused by the accumulation of materials outside. Since the controller 2 is electrically connected to the second motor 10, the reduction motor 9 and the first motor 4, the switches of these motors can be controlled through the controller 2, making the operation of the device more convenient. Since the threaded rods 16 are installed at the four corners of the bottom of the mounting bracket 1, and the support feet 15 are fixedly installed at the bottom of the threaded rods 16, the height of the support feet 15 can be adjusted through the threaded rods 16, so that the device can be stably placed on the ground with a certain height difference. All electrical equipment in this device is powered by an external power supply.
[0025] In one aspect of this embodiment, since the mounting partition 20 is fixedly installed on one side of the mounting bracket 1, it can effectively prevent materials from falling from both sides of the conveyor belt 8, so that there will be no accumulation of mud, stone powder on both sides of the conveyor, greatly reducing the cleaning cost. Since the movable plates 12 are movably installed on both sides of the mounting partition 20, and the discharge plate 11 is fixedly installed on one side of the movable plate 12, the angle of the discharge plate 11 can be adjusted through the movable plate, so that the angle of the conveyor when discharging can be controlled, facilitating discharging on the ground with different height differences.
[0026] In one aspect of this embodiment, since the first fixed pulley 14 is slidably connected to the chute 13, the first fixed pulley 14 can slide on the surface of the first fixed pulley 14 by unscrewing the hexagon bolt above the first fixed pulley 14, so that the position of the sweeper can be adjusted to facilitate the sweeper to better clean the residual materials on the surface of the conveyor belt 8, and the cleaned materials can be caught by the waste box 19 below the sweeper, avoiding the generation of cleaning costs due to the accumulation of materials outside.
[0027] In one aspect of this embodiment, since the controller 2 is electrically connected to the second motor 10, the reduction motor 9 and the first motor 4, the controller 2 can control the on / off of these motors, making the operation of the device more convenient. Since the threaded rods 16 are installed around the bottom of the mounting bracket 1, and the supporting feet 15 are fixedly installed at the bottoms of the threaded rods 16, the height of the supporting feet 15 can be adjusted through the threaded rods 16, so that the device can be stably placed on the ground with a certain height difference.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
