Description

Technical Field

[0001] The utility model relates to the technical field of screening structures, in particular to a vibrating screening structure. Background Art

[0002] In the construction industry, asphalt is a commonly used material for road construction and maintenance. Existing asphalt mixing plants first transport the raw materials to a screening structure, then to a weighing structure. The raw materials are added to the mixing structure according to the formula. After mixing is completed, the raw materials are loaded into transport vehicles and transported to the site for use.

[0003] The existing screening structure mainly sets the screen at a certain inclination angle. The mesh size of the screen can screen out raw materials with particle size larger than the mesh size. When the inclination angle of the screen is set too large and the number of mixed raw material particles added is too large, the screen can only screen part of the mixed raw materials.

[0024] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-4 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0025] The present application discloses a vibrating screening structure, referring to Figure 1-Figure 4 ,

[0026] A vibrating screening structure includes: a mounting frame 1, on which a screening disc 2, an adjustment component 3 and a vibration component 4 are movably mounted. The adjustment component 3 and the vibration component 4 are relatively arranged on both sides of the screening disc 2. The adjustment component 3 is used to adjust the inclination angle of the screening disc 2.

[0027] The screening disc 2 includes an upper cover plate and a disc body 202 . The upper cover plate is provided with a material inlet, and a screen 203 is provided in the disc body 202 .

[0028] The adjustment assembly 3 includes a first motor 301, a gear 302, a rotating rod 303, a rotating disk, a connecting rod 304 and an adjustment frame 305. Two gears 302 are meshed and are coaxially connected to the first motor 301 and the rotating rod 303 respectively. The rotating rod 303 bearing is installed on the mounting frame 1. Rotating disks are provided at both ends of the rotating rod 303. A connecting rod 304 is provided at the end of the rotating disk. An adjustment frame 305 is provided at one end of the connecting rod 304. Slide grooves 5 are provided on both sides of the disk body 202, and the adjustment frame 305 is slidably set on the slide grooves 5.

[0029] The two gears 302 are driven to rotate by the first motor 301. When one of the gears 302 rotates, the rotating rod 303 and the rotating disks at both ends of the rotating rod 303 are also driven to rotate. When the rotating disk rotates, the rotation is connected to the connecting rod 304, so that the angle of one end of the connecting rod 304 connected to the rotating disk changes. Therefore, the adjusting frame 305 at the other end of the connecting rod 304 drives the screening disc 2 to change its angle through the connecting rod 304, thereby adjusting the inclination angle of the screening disc 2.

[0030] The chute 5 is located below the screen 203 , and two chute 5 are respectively provided on both sides of the disc body 202 . The adjustment frame 305 is in an I-shape as a whole, and the ends of the adjustment frame 305 are respectively located in the four chute 5 .

[0031] The adjustment frame 305 is in an I-shape, and the four ends of the adjustment frame 305 are respectively located in the four sliding grooves 5 , thereby improving the stability of the disk body 202 .

[0032] The vibration component 4 includes a second motor 401, a transmission belt 402, a rotating shaft 403, a cam 404 and an impact block 405. The transmission belt 402 is connected to the second motor 401 and the rotating shaft 403. The bearings at both ends of the rotating shaft 403 are connected to the mounting frame 1. A cam 404 is provided on the rotating shaft 403. The cam 404 is located on one side of the disk body 202. An impact block 405 is provided on the side of the disk body 202 close to the cam 404. The cam 404 and the impact block 405 are interference fit.

[0033] The second motor 401 is started to rotate the rotating shaft 403 through the transmission belt 402. When the rotating shaft 403 rotates, the protrusion of the cam 404 and the impact block 405 are set to interfere with each other, thereby impacting the impact ore, thereby vibrating the disc body 202 for screening.

[0034] Optionally, a plurality of universal wheels 6 are evenly arranged on the bottom of the mounting frame 1 .

[0035] The implementation principle of a vibrating screening structure in the embodiment of the present application is as follows:

[0036] The first motor 301 drives the two gears 302 to rotate. When one of the gears 302 rotates, the rotating rod 303 and the rotating disks at both ends of the rotating rod 303 are also driven to rotate. When the rotating disk rotates, the rotation is connected to the connecting rod 304, so that the angle of the end of the connecting rod 304 connected to the rotating disk changes. The adjusting frame 305 at the other end of the connecting rod 304 drives the screening disk 2 to change its angle through the connecting rod 304, thereby adjusting the inclination angle of the screening disk 2.

[0037] The second motor 401 is started to rotate the rotating shaft 403 through the transmission belt 402. When the rotating shaft 403 rotates, the protrusion of the cam 404 and the impact block 405 are set to interfere with each other, thereby impacting the impact ore, thereby vibrating the disc body 202 for screening.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
