[0024] The present utility model will be further described below in conjunction with the accompanying drawings:

[0025] As Figures 1-5 shown, a bitumen modifier feeding mechanism includes a mixing drum 1. A feeding funnel 101 is fixedly connected to the top of the mixing drum 1. The modifier is added into the mixing drum 1 through the feeding funnel 101. An anti-blocking component is arranged in the feeding funnel 101. The anti-blocking component includes a vertical plate 301 bolted to the top of the mixing drum 1. A rotating motor 302 is bolted to one side of the vertical plate 301. The output end of the rotating motor 302 is connected to a rotating shaft 303 through a coupling. The rotating shaft 303 extends into the feeding funnel 101 and is fixedly connected with a plurality of circumferentially arranged paddles 304. While feeding, the rotating motor 302 is started. The rotating motor 302 drives the rotating shaft 303 to drive the paddles 304 to rotate, so as to stir the modifier in the feeding funnel 101 and prevent the feeding funnel 101 from being blocked.

[0026] A blanking plate 2 is fixedly connected between the inner walls of the mixing drum 1. A number of blanking holes are provided on the blanking plate 2. In order to ensure the feeding speed of other raw materials, other feeding pipes are arranged on the side wall of the mixing drum 1, and the feeding pipes are located below the blanking plate 2. A plurality of circumferentially arranged pushing plates 403 are rotatably connected to the inner wall of the mixing drum 1. The pushing plates 403 are in close contact with the top of the blanking plate 2. A power assembly is arranged between the blanking plate 2 and the inner top wall of the mixing drum 1. The power assembly is used to drive a plurality of pushing plates 403 to rotate around the central axis of the blanking plate 2. The power assembly includes a toothed ring 401 rotatably connected to the inner top wall of the mixing drum 1. A number of circumferentially arranged connecting rods 402 are fixedly connected to the bottom of the toothed ring 401. The pushing plates 403 are fixedly connected to the bottom of the connecting rods 402. A rotating shaft 404 is rotatably connected to the top wall of the mixing drum 1. A spur gear 405 is fixedly connected to the rotating shaft 404. The spur gear 405 meshes with the toothed ring 401. The toothed ring 401 drives the pushing plates 403 to rotate. The modifier on the blanking plate 2 is toggled by the pushing plates 403, so that the modifier evenly falls into the mixing drum 1, which is convenient for later mixing.

[0027] A linkage assembly is arranged between the power assembly and the anti-blocking assembly. The linkage assembly includes a driving bevel gear 406. The driving bevel gear 406 is fixedly connected to the rotating shaft 303. The top end of the rotating shaft 404 extends out of the mixing drum 1 and is fixedly connected to a driven bevel gear 407. The driven bevel gear 407 meshes with the driving bevel gear 406. When the rotating shaft 303 rotates, it will drive the driving bevel gear 406 to rotate. The driving bevel gear 406 meshes with the driven bevel gear 407, so as to drive the driven bevel gear 407 to drive the rotating shaft 404 to rotate. The rotating shaft 404 drives the spur gear 405 to rotate. The spur gear 405 meshes with the toothed ring 401, so as to drive the toothed ring 401 to rotate.

[0028] A knocking assembly is further arranged above the blanking plate 2. The knocking assembly is used to intermittently knock the blanking plate 2. The knocking assembly includes a number of protrusions 501 fixedly connected to the top of the blanking plate 2. Avoidance holes are provided on the pushing plates 403 for avoiding the protrusions 501. A telescopic rod 502 is fixedly connected to the bottom of the toothed ring 401. A knocking hammer 503 is fixedly connected to the bottom of the telescopic rod 502. A spring 504 is connected between the knocking hammer 503 and the toothed ring 401. The spring 504 is wound around the outer periphery of the telescopic rod 502. Both the protrusion 501 and the knocking hammer 503 are hemispherical, which is convenient for the relative movement between the protrusion 501 and the knocking hammer 503.

[0029] Working principle: The powder or granular modifier is added to the blanking plate 2 through the feeding hopper 101. While adding the material, the rotating motor 302 is started. The rotating motor 302 drives the rotating shaft 303 to drive the paddle 304 to rotate, stirring the modifier in the feeding hopper 101 to prevent the feeding hopper 101 from being blocked. While the rotating shaft 303 rotates, it will drive the driving bevel gear 406 to rotate. The driving bevel gear 406 meshes with the driven bevel gear 407, thereby driving the driven bevel gear 407 to drive the rotating shaft 404 to rotate. The rotating shaft 404 drives the full gear 405 to rotate. The full gear 405 meshes with the toothed ring 401, thereby driving the toothed ring 401 to rotate. The toothed ring 401 drives the push plate 403 to rotate, and the modifier on the blanking plate 2 is stirred by the push plate 403, so that the modifier evenly falls into the mixing cylinder 1, which is convenient for later stirring and mixing. During the rotation of the toothed ring 401, the knocking hammer 503 will gradually move upward under the restriction of the protrusion 501. When the knocking hammer 503 is separated from the protrusion 501, the knocking hammer 503 quickly moves downward under the action of the elastic force of the spring 504, knocking on the blanking plate 2 to prevent the blanking plate 2 from being blocked and improving the blanking efficiency.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
