A feed port 201 is provided on the side of the casing 200, and a discharge port 202 is provided at the bottom of the casing 200. The lifting assembly is used to lift the aggregate entering the casing 200 from the feed port 201 to the top of the casing 200 and then discharge it. The lifting assembly adopts an existing structure including a lifting chain, a hopper arranged on the lifting chain, and a motor driving the lifting chain; the base 100 is also provided with a material receiving assembly 300 and a material guiding assembly 400. And a feeding component 500, wherein the receiving component 300 includes a receiving hopper 301 arranged at the bottom of the housing 200 and connected to the drop port 202, a belt conveyor 302 is provided in the receiving hopper 301 and a discharge port 303 is provided on the side of the receiving hopper 301, the belt conveyor 302 is located below the drop port 202, one end of the belt conveyor 302 passes through the discharge port 303 and extends out of the receiving hopper 301, the aggregate dropped from the lifting component passes through the drop port 202 and falls on the belt conveyor 302, and the belt conveyor 302 can transport the aggregate from the discharge port 303 to the receiving hopper when it is running. The material guide assembly 400 includes a guide pipe 401, a first storage hopper 402 and a first discharge pipe 403 which are connected in sequence. The guide pipe 401 is connected to the discharge port 303. The aggregate is sent out of the discharge port 303 by the belt conveyor 302 and falls into the guide pipe 401 and enters the first storage hopper 402 along the guide pipe 401; the feeding assembly 500 includes a second storage hopper 501 and the first discharge pipe 403 is connected to the second storage hopper 501. The second storage hopper 501 is provided with a vertical feeding pipe 502 and the top of the feeding pipe 502 is provided with a A discharge pipe 503 is provided in the feed pipe 502, and a rotatable feed rod 504 is provided on the feed rod 504. A feed motor 506 is provided on the second storage hopper 501 and is transmission-connected to the feed rod 504. The aggregate stored in the first storage hopper 402 can be input into the second storage hopper 501 along the first discharge pipe 403. After entering the second storage hopper 501, the aggregate can be transported to the discharge pipe 503 under the action of the spiral blade 505 and enter the feed port 201 along the discharge pipe 503, thereby inputting the aggregate falling from the lifting assembly into the lifting assembly again.

[0016] Specifically, the working process of the asphalt aggregate elevator provided in this embodiment when recycling aggregate is as follows: after the aggregate falls from the lifting assembly, it passes through the drop port 202 and falls onto the belt conveyor 302, and the belt conveyor 302 moves the aggregate so that the aggregate passes through the discharge port 303 and is input into the guide pipe 401, and the aggregate falls into the first storage hopper 402 along the guide pipe 401 and is stored in the first storage hopper 402, and the aggregate in the first storage hopper 402 can enter the second storage hopper 501 along the first discharge pipe 403, and when the feeding rod 504 rotates under the drive of the feeding motor 506, the spiral blade 505 rotates synchronously and transports the aggregate in the second storage hopper 501 along the feeding pipe 502 to the discharge pipe 503, and after entering the discharge pipe 503, the aggregate enters the feed port 201 on the casing 200 along the discharge pipe 503 and falls into the lifting assembly again. The asphalt aggregate elevator provided in this embodiment can automatically recycle and reuse aggregates, avoid aggregate retention and promptly recover aggregates dropped from the lifting component, and put the aggregates into the feed port 201 again for transportation to prevent aggregate retention from affecting the normal asphalt mixing operation, thereby saving time and manpower required for aggregate recovery.

[0017] like Figure 3 As shown, a guide plate 304 is provided in the receiving hopper 301, and the guide plate 304 is located between the discharge port 202 and the conveyor belt 302. The guide plate 304 provided in the receiving hopper 301 is used to guide the aggregate passing through the discharge port 202 to fall onto the conveyor belt 302, ensuring that the aggregate is smoothly transported to the guide pipe 401 by the conveyor belt 302, and preventing the aggregate from falling outside the conveyor belt 302 after entering the receiving hopper 301, causing the aggregate to accumulate below the conveyor belt 302.

[0018] Please combine Figure 3 and Figure 4 The guide pipe 401 covers the opening of the discharge port 303, and one end of the conveyor belt 302 extending from the discharge port 303 extends into the guide pipe 401. One end of the guide pipe 401 is attached to the receiving hopper 301 and covers the opening of the discharge port 303, so that the end of the conveyor belt 302 extending from the discharge port 303 enters the guide pipe 401. Aggregates sent out of the receiving hopper 301 by the conveyor belt 302 all fall into the guide pipe 401, preventing aggregates from falling out of the guide pipe 401 and causing aggregate loss. A vibration motor is installed on the guide pipe 401, which is used to vibrate the guide pipe 401 to prevent aggregates from accumulating in the guide pipe 401 and forming a blockage.

[0019] Specifically, two support plates 305 are spaced apart on the receiving hopper 301. The two support plates 305 are located on opposite sides of the discharge port 303 and extend into the guide pipe 401. The end of the conveyor belt 302 extending from the discharge port 303 is mounted on the support plates 305. The two support plates 305 provided on the receiving hopper 301 are used to mount the conveyor belt 302, ensuring a secure fit between the conveyor belt 302 and the receiving hopper 301 and maintaining stability at the end of the conveyor belt 302 extending into the guide pipe 401, thereby improving the structural stability of the asphalt aggregate elevator.

[0020] like Figure 1 and Figure 2 As shown, a three-way valve 404 is provided on the first storage hopper 402, and the first discharge pipe 403 is connected to the three-way valve 404. The three-way valve 404 is used to control the connection or disconnection between the first storage hopper 402 and the first discharge pipe 403. When the three-way valve 404 is operated to connect the first discharge pipe 403 and the first storage hopper 402, the aggregate in the first storage hopper 402 continuously falls into the first discharge pipe 403 and enters the second storage hopper 501 along the first discharge pipe 403. At this time, the recovered aggregate is re-input into the feed port 201. When the three-way valve 404 is operated to disconnect the first discharge pipe 403 and the first storage hopper 402, the recovered aggregate is temporarily stored in the first storage hopper 402, so that the time for re-inputting the aggregate dropped from the lifting assembly into the feed port 201 can be selected according to production needs, or the dropped aggregate can be removed and used for other purposes.

[0021] In this embodiment, the material guide assembly 400 further includes a second discharge pipe 405, which is in communication with the three-way valve 404. The three-way valve 404 is operated to connect or disconnect the second discharge pipe 405 with the first storage hopper 402. When the second discharge pipe 405 is connected to the first storage hopper 402, the aggregate stored in the first storage hopper 402 is discharged along the second discharge pipe 405, thereby removing the recovered aggregate from the first storage hopper 402.

[0022] Please refer to Figure 2 The base 100 is further provided with a receiving bucket, and the opening of the second discharge pipe 405 faces the receiving bucket. The receiving bucket is used to receive the aggregate discharged from the second discharge pipe 405, so as to collect the aggregate taken out from the first storage hopper 402 and transport the taken out aggregate.

[0023] Please combine Figure 1 and Figure 3The second hopper 501 is provided with a sealing cover 507, which covers the opening of the second hopper 501. The guide tube 401 is vertically mounted on the sealing cover 507. The sealing cover 507 is provided with a first connector 508 that mates with the first discharge tube 403. The sealing cover 507 covers the opening of the second hopper 501 to prevent aggregate from falling out of the second hopper 501 as it moves from the first hopper 402 to the second hopper 501 along the first discharge tube 403. The first connector 508 is provided on the sealing cover 507 to connect with the first discharge tube 403, ensuring a secure fit between the first discharge tube 403 and the second hopper 501.

[0024] Specifically, the device further includes a heating assembly, which includes a matching hot air blower and a heating pipe. The sealing cover 507 is provided with a second connector 509 that matches the heating pipe. The hot air flow generated by the hot air blower is input into the second storage hopper 501 along the heating pipe to heat the aggregate in the second storage hopper 501, thereby preventing the temperature of the aggregate from being lower than the required temperature when it returns to the feed port 201, ensuring that the recovered aggregate can be smoothly put into production. The heating pipe is connected to the second storage hopper 501 by docking with the second connector 509, ensuring a secure connection between the heating pipe and the second storage hopper 501 to prevent leakage of the hot air flow generated by the hot air blower.

[0025] like Figure 4 As shown, a discharge port 510 is provided at the top of the conveying pipe 502. The height of the discharge port 510 is higher than the height of the feed inlet 201, and the discharge pipe 503 is connected to the discharge port 510. The discharge port 510 provided at the top of the conveying pipe 502 is used to allow aggregate to pass through the conveying pipe 502 and enter the discharge port 510. The height of the discharge port 510 is set higher than the height of the feed inlet 201, so that after the aggregate passes through the discharge port 510 and enters the discharge pipe 503, it falls smoothly into the feed inlet 201 under the action of gravity, allowing the aggregate to be smoothly input into the feed inlet 201.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
