Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and more specifically, to an asphalt concrete aggregate screening device. Background Technology

[0002] In the production of asphalt concrete, screening equipment is usually used to screen aggregates. However, in actual use, there are still some drawbacks. For example, when using traditional screening equipment, aggregates often fall directly onto the screen surface, resulting in excessive aggregate accumulation in some areas of the screen and insufficient aggregate in others. Excessive accumulation will increase the burden on the screen, reduce screening efficiency, and may also cause excessive wear on the screen. On the other hand, areas with insufficient aggregate cannot fully utilize the screening capacity of the screen, thus reducing the overall working efficiency of the equipment and the practicality of the screening process. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an asphalt concrete aggregate screening device to solve the problem of uneven distribution of aggregate on the screen surface in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an asphalt concrete aggregate screening device, comprising a screening device body, wherein the asphalt concrete aggregate screening device further comprises...

[0005] Feed hopper;

[0006] A guide plate, wherein the guide plate is fixedly installed inside the guide plate, the guide plate is set at an angle, and a material passage bag is provided at the bottom of the guide plate, the material passage bag being a flexible structure;

[0007] A connecting cavity is provided at the bottom of the feeding hopper, and a material spreading hopper is fixedly connected to the bottom of the connecting cavity. The top of the connecting cavity is connected to the bottom of the material bag.

[0008] A connecting frame is fixedly installed on the front of the feeding hopper. A motor is fixedly connected to the bottom of the connecting frame. A rotating wheel is fixedly connected to the drive shaft of the motor. A transmission belt is provided on the surface of the rotating wheel. A rotating wheel is connected to a second rotating wheel through the transmission belt. A connecting shaft is fixedly connected to one side of the second rotating wheel. One end of the connecting shaft is fixedly connected to one side of the connecting cavity along its length.

[0009] It also includes a fixed base and a second connecting shaft. The fixed base is fixedly installed on the side of the feed hopper surface opposite to the motor. The surface of the fixed base is rotatably connected to one end of the second connecting shaft. The end of the second connecting shaft relative to the fixed base is fixedly connected to the side of the connecting shaft relative to the first connecting shaft in the length direction of the connecting cavity.

[0010] It also includes auxiliary components, which are disposed on top of the main body of the screening device.

[0011] The auxiliary components include a shield, a connecting seat, a fan, a first connecting pipe, a collection bin, a connecting end, a second connecting pipe, and a dust collection chamber. The shield is fixedly installed on the top of the main body of the screening equipment, and the top surface of the shield is fixedly connected to the bottom of the feeding bin. The fan is fixedly installed on the front of the main body of the screening equipment via the connecting seat. The air outlet of the fan is fixedly connected to the bottom of the collection bin via the first connecting pipe, and the connecting end is rotatably connected to the top of the collection bin. The dust collection chamber is arranged opposite to the left and right sides of the shield. The second connecting pipe is fixedly connected to the surface of the dust collection chamber, and the bottom end of the second connecting pipe is threadedly connected to the inner wall of the connecting end.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] In the above scheme, the aggregate to be screened is placed in the feed hopper. The aggregate enters the feed bag through the guide plate and falls into the connecting cavity. At the same time, the motor set in front of the feed hopper is started, which drives the first rotating wheel to rotate. At this time, the second rotating wheel rotates synchronously under the transmission of the transmission belt, so that the spreading hopper deflects at a certain angle above the screen. During the swinging process of the spreading hopper, the aggregate can be evenly distributed on the screen surface. When the spreading hopper rotates to the maximum angle, the motor drives the first rotating wheel to reverse, so that the spreading hopper deflects in the opposite direction to continue to distribute the aggregate. This achieves uniform distribution of aggregate, avoids aggregate accumulation on the screen surface and affects the screening effect, and improves the practicality of the device.

[0014] The dust generated when the aggregate falls onto the screen surface can be contained by the shield set on the top of the screening equipment. At the same time, the dust is sucked into the dust collection chamber by the wind generated by the fan. The dust enters the collection bin through the connecting pipe 2 for temporary storage, thus realizing the collection of dust and further improving the practicality of the device.

At the same time, the motor 8 set in front of the feeding hopper 2 is started, which drives the rotating wheel 9 to rotate. At this time, the rotating wheel 11 rotates synchronously under the transmission action of the transmission belt 10, so that the spreading hopper 6 deflects at a certain angle above the screen. During the swinging process of the spreading hopper 6, the aggregate can be evenly distributed on the screen surface. When the spreading hopper 6 rotates to the maximum angle, the motor 8 drives the rotating wheel 9 to reverse, so that the spreading hopper 6 deflects in the opposite direction to continue to distribute the aggregate.
