Since the second belt conveyor in the application is located below the first belt conveyor, and the raw materials in the flow guide hopper can fall to the first belt conveyor and the second belt conveyor, compared with the prior art in which multiple flow guide hoppers are arranged, the load of the conveying assembly is reduced under the premise of ensuring the raw material conveying and discharging, thereby reducing the failure rate of the asphalt concrete raw material conveying equipment.

[0036] The application discloses an asphalt concrete raw material conveying device.

[0037] Referring to Figures 1 to 4 The application discloses an asphalt concrete raw material conveying device, which comprises a conveying assembly 1 and a flow guide hopper 2. The conveying assembly 1 has a conveying start end and a conveying end opposite to the conveying start end. The flow guide hopper 2 is arranged at the conveying start end. The conveying assembly 1 comprises a first belt conveyor 11 and a second belt conveyor 12 arranged below the first belt conveyor 11. The flow guide hopper 2 has a first discharging opening 21 and a second discharging opening 22. The first belt conveyor 11 has a first material receiving section opposite to the first discharging opening 21. The second belt conveyor 12 has a second material receiving section opposite to the second discharging opening 22. The second material receiving section is located outside the first material receiving section.

[0038] It can be understood that the first discharging opening 21 and the second discharging opening 22 are both arranged at the bottom of the flow guide hopper 2.

[0039] When the asphalt concrete raw material conveying device is used to convey raw materials, the raw materials are poured into the flow guide hopper 2, and then part of the raw materials falls to the first material receiving section of the first belt conveyor 11 through the first discharging opening 21, and the remaining part of the raw materials falls to the second material receiving section of the second belt conveyor 12 through the second discharging opening 22, so that the raw materials are conveyed to the mixing building by the first belt conveyor 11 and the second belt conveyor 12. Since the second belt conveyor 12 in the application is arranged below the first belt conveyor 11, and the raw materials in the flow guide hopper 2 can fall to the first belt conveyor 11 and the second belt conveyor 12, compared with the prior art in which the flow guide hopper 2 is arranged in multiple, the load of the conveying assembly 1 is reduced under the premise of ensuring the raw material conveying and discharging, so as to reduce the failure rate of the asphalt concrete raw material conveying device.

[0040] Preferably, referring to Figure 1, the first belt conveyor 11 is located outside the second belt conveyor 12 at the end away from the flow guide hopper 2, so that the raw materials conveyed by the first belt conveyor 11 and the raw materials conveyed by the second belt conveyor 12 fall at different positions, thereby increasing the uniformity of the asphalt concrete raw material conveying device.

[0041] In a preferred embodiment, referring to Figure 3 and Figure 4 , the flow guide hopper 2 is provided with a flow guide 23 located between the first discharge port 21 and the second discharge port 22, and the flow guide 23 has oppositely arranged first and second flow guide surfaces, and the distance between the first and second flow guide surfaces gradually increases from top to bottom.

[0042] Since the flow guide 23 is located between the first discharge port 21 and the second discharge port 22, on the one hand, the flow guide 23 separates the first discharge port 21 from the second discharge port 22, and on the other hand, the flow guide 23 can guide the raw materials to fall more smoothly through the first discharge port 21 and the second discharge port 22, thereby ensuring the smoothness of the raw materials falling.

[0043] More preferably, referring to Figure 3 and Figure 4 , the flow guide 23 is triangular in cross-sectional shape to increase the guiding effect of the raw materials and avoid the accumulation of raw materials on the top of the flow guide 23.

[0044] The application does not make specific limitations on the fixing method of the flow guide hopper 2, preferably, referring to Figure 1 and Figure 2 , the bottom of the flow guide hopper 2 is provided with a connecting piece 24 connected to the frame of the first belt conveyor 11 and the second belt conveyor 12, which on the one hand realizes the fixed connection of the flow guide hopper 2 to the first belt conveyor 11 and the second belt conveyor 12, and on the other hand increases the stability of the flow guide 23, and makes the distance between the first discharge port 21 and the first belt conveyor 11 and the distance between the second discharge port 22 and the second belt conveyor 12 more advanced, so as to avoid the raw materials falling through the flow guide hopper 2 from spattering outside the conveying assembly 1, thereby ensuring the cleanliness of the environment.

[0045] Further, the connecting piece 24 is fixedly connected to the frame of the first belt conveyor 11 and the second belt conveyor 12 through a bolt pair to increase the stability of the flow guide hopper 2.

[0046] In other embodiments, the flow guide hopper 2 can also be located on the top of the first belt conveyor 11 through a support or other structure.

[0047] In a preferred embodiment, referring to Figure 3 and Figure 4The side of the flow guide hopper 2 corresponding to the first discharge port 21 and the second discharge port 22 is provided with a discharge gap 25.

[0048] It can be understood that the discharge gap 25 is provided with two, one of which corresponds to the arrangement of the first belt conveyor 11, and the other corresponds to the arrangement of the second belt conveyor 12.

[0049] The raw materials falling onto the first belt conveyor 11 through the first discharge port 21 move to the outside of the discharge gap 25 under the action of the first belt conveyor 11, so that the wall of the flow guide hopper 2 avoids the raw materials, thereby avoiding the situation that the wall of the flow guide hopper 2 scrapes the raw materials, and further improving the conveying efficiency of the raw materials; in addition, the distance between the first discharge port 21 and the first belt conveyor 11 can be closer, so as to further avoid the situation that the raw materials splash outside the conveying assembly 1. The raw materials falling onto the second belt conveyor 12 through the second discharge port 22 move to the outside of the discharge gap 25 under the action of the second belt conveyor 12, so that the wall of the flow guide hopper 2 avoids the raw materials, thereby avoiding the situation that the wall of the flow guide hopper 2 scrapes the raw materials, and further improving the conveying efficiency of the raw materials.

[0050] Further, referring to Figure 3 and Figure 4 , both sides of the discharge gap 25 are provided with guide plates 251, and the distance between the two guide plates 251 gradually decreases in the direction close to the conveying end, that is, each discharge gap 25 is provided with guide plates 251 on both sides, and the guide plates 251 are located on both sides in the material conveying direction, so that the raw materials moving to the position of the guide plates 251 move towards the middle position of the conveying assembly 1 in the width direction under the action of the two guide plates, so as to avoid the situation that the raw materials are close to the side of the conveying assembly 1 and easily fall outside the conveying assembly 1, thereby ensuring the conveying efficiency of the raw materials and the cleanliness of the environment.

[0051] In a preferred embodiment, referring to Figure 3 and Figure 4 , the flow guide hopper 2 is provided with a control plate 3 located above the flow guide 23, the control plate 3 is provided with a discharge port, and the control plate 3 is slidingly connected with the flow guide hopper 2, so that the control plate 3 has a first position, a second position and a middle position between the first position and the second position. When the control plate 3 is in the first position, the discharge port is in communication with the first discharge port 21; when the control plate 3 is in the middle position, the discharge port is in communication with the first discharge port 21 and the second discharge port 22; and when the control plate 3 is in the second position, the discharge port is in communication with the second discharge port 22.

[0052] It should be noted that when the control plate 3 is in the first position, part of the drop port is located outside the diversion hopper 2 away from the second drop port 22, so that the drop port can only communicate with the first drop port 21; when the control plate 3 is in the second position, part of the drop port is located outside the diversion hopper 2 away from the first drop port 21, so that the drop port can only communicate with the second drop port 22; and when the control plate 3 is in the intermediate position, the drop port is opposite to the first drop port 21 and the second drop port 22, so that the drop port communicates with both of them.

[0053] When the first belt conveyor 11 and the second belt conveyor 12 can work normally, the control plate 3 is driven to the intermediate position, so that the drop port communicates with the first drop port 21 and the second drop port 22, so that the raw materials in the diversion hopper 2 can fall onto the first belt conveyor 11 and the second belt conveyor 12; if the first belt conveyor 11 needs to be repaired due to failure, the control plate 3 is driven to the second position, so that the drop port communicates with the second drop port 22, so that the raw materials in the diversion hopper 2 can only fall onto the second belt conveyor 12, so as to facilitate the repair of the first belt conveyor 11; if the second belt conveyor 12 needs to be repaired due to failure, the control plate 3 is driven to the first position, so that the drop port communicates with the first drop port 21, so that the raw materials in the diversion hopper 2 can only fall onto the first belt conveyor 11, so as to facilitate the repair of the second belt conveyor 12. And when the demand for raw materials is small, the first belt conveyor 11 or the second belt conveyor 12 can also be started to reduce the power consumption of the asphalt concrete raw material conveying equipment.

[0054] Further, referring to Figure 3 and Figure 4 Both ends of the control plate 3 are provided with stop ribs 31, and when the control plate 3 is in the first position or the second position, the two stop ribs 31 respectively abut against the diversion hopper 2.

[0055] Since the control plate 3 is in the first position or the second position, the two stop ribs 31 respectively abut against the diversion hopper 2, so that the cooperation of the stop rib 31 and the diversion hopper 2 limits the movement range of the control plate 3, so as to avoid the control plate 3 moving too much and separating from the diversion hopper 2, thereby ensuring the connection stability of the control plate 3 and the diversion hopper 2.

[0056] Preferably, the stop rib 31 is located at the bottom of the control plate 3, so as to avoid the stop rib 31 blocking the raw materials falling onto the control plate 3, thereby ensuring the normal sliding of the control plate 3.

[0057] Further, referring to Figure 3 and Figure 4The first follow-up plate 32 and the second follow-up plate 33 are arranged in the flow guide hopper 2 and can move along with the control plate 3, so that when the control plate 3 is located at the first position, the first follow-up plate 32 is in an inclined state to guide the raw materials to the first discharge port 21, and when the control plate 3 is located at the second position, the second follow-up plate 33 is in an inclined state to guide the raw materials to the second discharge port 22.

[0058] Specifically, when the control plate 3 is located at the first position, the first follow-up plate 32 is in an inclined state, so that the raw materials can fall to the first belt conveyor 11 through the first discharge port 21 under the action of the first follow-up plate 32, thereby avoiding the accumulation of raw materials in the flow guide hopper 2; when the control plate 3 is located at the second position, the second follow-up plate 33 is in an inclined state, so that the raw materials can fall to the second belt conveyor 12 through the second discharge port 22 under the action of the second follow-up plate 33, thereby avoiding the accumulation of raw materials in the flow guide hopper 2.

[0059] Further, referring to Figure 3 and Figure 4 , the wall of the discharge port is provided with a sliding groove 34, and the first follow-up plate 32 and the second follow-up plate 33 are both provided with a connecting column 321 located in the sliding groove 34.

[0060] When the control plate 3 is driven from the middle position to the first position, the connecting column 321 of the first follow-up plate 32 moves synchronously with the control plate 3 under the action of the end wall of the sliding groove 34, so that the first follow-up plate 32 gradually enters an inclined state to realize synchronous movement of the first follow-up plate 32 with the control plate 3, and at this time, the connecting column 321 on the second follow-up plate 33 slides relative to the sliding groove 34 to avoid the movement of the second follow-up plate 33 along with the control plate 3; when the control plate 3 is driven from the middle position to the second position, the connecting column 321 of the second follow-up plate 33 moves synchronously with the control plate 3 under the action of the end wall of the sliding groove 34, so that the second follow-up plate 33 gradually enters an inclined state to realize synchronous movement of the second follow-up plate 33 with the control plate 3, and at this time, the connecting column 321 on the first follow-up plate 32 slides relative to the sliding groove 34 to avoid the movement of the first follow-up plate 32 along with the control plate 3.

[0061] Further, referring to Figure 3 and Figure 4 Figure 3 Figure 4 , the flow guide hopper 2 is provided with a connecting groove 26 extending in the vertical direction, and the top end of the first follow-up plate 32 and the second follow-up plate 33 is provided with a limiting column 331 located in the connecting groove 26.

[0062] When the first follower plate 32 follows the movement of the control plate 3, the limiting column 331 on the first follower plate 32 slides relative to the connecting groove 26, thereby increasing the binding point of the first follower plate 32, so as to ensure the stability of the connection between the first follower plate 32 and the flow guide hopper 2; when the second follower plate 33 follows the movement of the control plate 3, the limiting column 331 on the second follower plate 33 slides relative to the connecting groove 26, thereby increasing the binding point of the first follower plate 32, so as to ensure the stability of the connection between the second follower plate 33 and the flow guide hopper 2.

[0063] The structure of the connecting groove 26 is not limited in the present application, which can be a groove structure provided on the inner wall of the flow guide hopper 2, or can be formed by the rib provided on the inner wall of the flow guide hopper 2 and the inner wall of the flow guide hopper 2.

[0064] Further, the flow guide hopper 2 is provided with an elastic member corresponding to the first follower plate 32 and the second follower plate 33, which can exert an elastic force on one end of the bottom of the first follower plate 32 towards the direction away from the first discharge port 21, so as to increase the stability of the first follower plate 32, and can exert an elastic force on one end of the bottom of the second follower plate 33 towards the direction away from the second discharge port 22, so as to increase the stability of the second follower plate 33.
