[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figure 1-5 As shown, this embodiment proposes an asphalt concrete vibrating screen, including a vibration damping component 1 and a discharging component 4. The top of the vibration damping component 1 is provided with a bolt-assembled angle adjustment mechanism 2, and the top side of the angle adjustment mechanism 2 is provided with a bolt-assembled feeding screening component 3. The outer side of one end of the feeding screening component 3 is provided with a bolt-sleeved discharging component 4.

[0023] The discharging component 4 includes a divider 401, a discharging cylinder 402, an upper door panel 403, a middle door panel 404, and a lower door panel 405. The divider 401 is located on the outer side of one end of the feeding and screening component 3. The discharging cylinder 402 is located on the outer side of one end of the divider 401. The upper door panel 403 is located at the upper output end of the discharging cylinder 402. The middle door panel 404 is located at the middle output end of the discharging cylinder 402. The lower door panel 405 is located at the lower output end of the discharging cylinder 402.

[0024] The middle door panel 404 and the lower door panel 405 are symmetrically distributed along the central axis of the upper door panel 403.

[0025] In this embodiment, when material needs to be discharged, the air distribution cylinder 402 is activated in sequence to output power and drive the output end to extend and retract. In this way, the material is finally discharged by opening and closing the upper door plate 403, the middle door plate 404 and the lower door plate 405 in stages.

[0026] The vibration damping component 1 includes a pressure-reducing pad 101, a shock absorber 102, a pad plate 103, a bushing frame 104, a first transmission wheel set 105, a first motor 106, a vibrating cylinder 107, and an eccentric wheel set 108. The shock absorber 102, which mounts the pad plate 103, is arranged above the pressure-reducing pad 101. The bushing frame 104, which mounts the vibrating cylinder 107, is arranged above and around the pad plate 103. The eccentric wheel set 108, which is connected to the output end of the first transmission wheel set 105, is arranged inside the vibrating cylinder 107. The first transmission wheel set 105 is connected to the output end of the first motor 106.

[0027] In this embodiment, since the shock absorber 102 has a shock absorption function, the first motor 106 can output power to drive the output end to run, so that the first motor 106 can output power to drive the first transmission wheel set 105 to output transmission. Through the output transmission of the first transmission wheel set 105, the eccentric wheel set 108 inside the vibrating cylinder 107 can be driven to run and generate vibration force.

[0028] The angle adjustment mechanism 2 includes a slotted plate 201, a second motor 202, a second transmission wheel set 203, a lead screw set 204, a slider 205, a lower hinge base 206, an upper hinge base 207, an angle plate 208, and a fixed hinge seat 209. The slotted plate 201 is bolted to the top side of the bushing frame 104. The slotted plate 201 is provided with a second transmission wheel set 203 that connects to the output end of the second motor 202, and the output end of the second transmission wheel set 203 is provided with a lead screw set 204 that is threadedly connected to the slider 205.

[0029] In this embodiment, when material needs to be discharged after screening, the second motor 202 on the slotted plate 201 outputs power to drive the output end to run, so that the second transmission wheel group 203 can drive the screw group 204 to run the slider 205 to a suitable position.

[0030] The outer side of the slider 205 is hinged to the upper hinge base 207 via the lower hinge base 206, and an angle plate 208 is provided at one end of the upper hinge base 207. A fixed hinge seat 209 with bolt connection is provided below one end of the angle plate 208.

[0031] In this embodiment, when the slider 205 is running, the lower hinge base 206 and the upper hinge base 207 cooperate with the fixed hinge base 209 to adjust the angle plate 208 to a suitable angle position, which facilitates the feeding and screening component 3 and the discharging component 4 to discharge materials.

[0032] The feeding screening assembly 3 includes a through plate 301, a side strip 302, an end plate 303, a feed port 304, an inclined plate 305, an assembly frame 306, a coarse mesh cover 307, and a fine mesh cover 308. The through plate 301 is located above the angle plate 208. The outer side of the through plate 301 is provided with an end plate 303 bolted to the side strip 302. The feed port 304 for mounting the inclined plate 305 is provided above one end of the through plate 301.

[0033] In this embodiment, when feeding is required, the material is fed into the through plate 301 through the feed port 304 in conjunction with the inclined plate 305 to achieve the feeding operation process.

[0034] An assembly frame 306 for bolt assembly is provided on the inner side of the through plate 301. A coarse mesh cover 307 is provided on the upper inner side of the assembly frame 306, and a fine mesh cover 308 is provided on the lower inner side of the assembly frame 306.

[0035] In this embodiment, under the action of vibration, the coarse mesh cover 307 on the inner side of the upper part of the assembly frame 306 and the fine mesh cover 308 on the inner side of the upper part of the assembly frame 306 can achieve the effect of screening the material.

[0036] The working principle of this asphalt concrete vibrating screen is as follows: Because the shock absorber 102 has a damping function, the first motor 106 outputs power to drive the output end, which in turn drives the first transmission wheel set 105 for output transmission. This first transmission wheel set 105 then drives the eccentric wheel set 108 inside the vibrating cylinder 107 to generate vibration. When feeding is required, the material is fed into the through plate 301 through the feed inlet 304 in conjunction with the inclined plate 305. Under the action of vibration, the material is screened through the coarse mesh cover 307 and the fine mesh cover 308 on the inner side of the upper part of the assembly frame 306. The effect of the process is that when the material needs to be discharged after screening, the second motor 202 on the slotted plate 201 outputs power to drive the output end to run, so that the second transmission wheel group 203 drives the screw group 204 to run the slider 205 to a suitable position. When the slider 205 runs, the lower hinge base 206 and the upper hinge base 207 cooperate with the fixed hinge base 209 to adjust the angle plate 208 to a suitable angle position, which facilitates the discharge of the feeding screening component 3 and the multiple discharge component 4. When the material needs to be discharged, the air distribution cylinder 402 is activated in sequence to output power to drive the output end to extend and retract. In this way, the upper door plate 403, the middle door plate 404 and the lower door plate 405 are opened and closed in stages to facilitate the final output of the material.
