Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of asphalt feeding machines, specifically relating to an asphalt concrete feeding machine. Background Technology
[0002] In modern society, infrastructure construction, as a crucial support for national economic development, encompasses numerous fields such as roads, bridges, airports, and ports. Asphalt concrete, a key material widely used in these infrastructure constructions, plays an irreplaceable role due to its unique performance advantages. Asphalt concrete is a composite material made from asphalt and mineral aggregates (crushed stone, sand, mineral powder, etc.) through a rational proportioning and heating process. It possesses good flexibility, effectively adapting to foundation deformation and repeated vehicle loads, reducing pavement cracks and thus extending road lifespan. Simultaneously, asphalt concrete has a smooth surface, providing high driving comfort, reducing vehicle noise and vibration, and improving traffic safety and efficiency. With technological advancements, some simple mechanical feeding equipment has gradually been applied to asphalt concrete production. For example, fixed conveyor belts or elevators are used to transport asphalt to designated locations. However, most of these devices have design flaws; during the discharge process, asphalt can only be discharged from fixed outlets, leading to relatively concentrated asphalt accumulation within vehicles or equipment. Therefore, the inventors proposed an asphalt concrete feeding machine. Utility Model Content
[0003] (1) Technical problems to be solved
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an asphalt concrete feeding machine, which aims to solve the problem that in the process of discharging material, asphalt can only be discharged from a fixed discharge port, resulting in the asphalt accumulating in a relatively concentrated position in the vehicle or equipment.
[0005] (2) Technical solution
[0006] To solve the above-mentioned technical problems, this utility model provides an asphalt concrete feeding machine, including a support frame, a storage bin, and a movable frame. The storage bin is located beside the support frame, and the movable frame is slidably installed on the inner side above the support frame. A protective shell is fixedly installed above the storage bin, and a pump is installed inside the protective shell. The output end of the pump is connected to a transmission hose, and the other end of the transmission hose is connected to the transmission box. A transmission pipe is provided at the bottom of the transmission box, and a sliding ring is fixedly sleeved on the outer wall of the bottom end of the transmission pipe. A movable block is fixedly connected to the side wall of the sliding ring, and the movable block is slidably connected to the inner wall of the movable frame.
[0007] Preferably, the inner wall of the movable frame is provided with an L-shaped mounting hole, the movable block is L-shaped, and the movable block is slidably adapted to the mounting hole.
[0008] Preferably, an internal screw is horizontally installed inside the mounting hole, the internal screw thread passes through the moving block, and a motor connected to the internal screw is fixedly installed inside the moving frame.
[0009] Preferably, a stirring rod is rotatably mounted inside the transmission tube, and a motor connected to the stirring rod is mounted on the outer wall of the transmission tube.
[0010] Preferably, an inner groove is horizontally formed on the inner wall of the support frame, and a lead screw is installed inside the inner groove.
[0011] Preferably, a drive motor is fixed on the outer wall of the support frame, and the drive motor is connected to a lead screw.
[0012] Preferably, a feed hopper is installed on the side wall of the storage box.
[0013] (3) Beneficial effects
[0014] Compared with existing technologies, the advantages of this invention are as follows: Traditional simple mechanical feeding equipment has a fixed discharge port, which easily leads to localized accumulation of asphalt inside the vehicle, affecting the quality of asphalt concrete. This feeding machine uses a motor to drive the internal screw to rotate, causing the moving block to move horizontally within the mounting hole, thereby allowing the transmission pipe to slide horizontally within the moving frame. This dual-movement mechanism allows the transmission pipe to move flexibly above the vehicle, ensuring that the asphalt is evenly distributed inside the vehicle and preventing localized accumulation.
[0015] An agitator is installed inside the transmission pipe and driven by a motor to rotate. During the discharge of asphalt through the transmission pipe, the agitator continuously agitates the asphalt, preventing it from clogging the pipe due to its high viscosity and poor flowability. This ensures that the asphalt can be discharged smoothly and stably into the vehicles, improving feeding efficiency and reducing production downtime caused by equipment failure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This specific embodiment is an asphalt concrete feeding machine, the structural diagram of which is shown below. Figure 1 , Figure 2 As shown, the system includes a support frame 2, a storage bin 7, and a movable frame 3. The storage bin 7 is located beside the support frame 2, and the movable frame 3 is slidably mounted on the inner side above the support frame 2. A protective shell 6 is fixedly mounted above the storage bin 7, and a pump is installed inside the protective shell 6. The output end of the pump is connected to a transmission hose 5, and the other end of the transmission hose 5 is connected to a transmission box 4. An inner groove 9 is horizontally opened on the inner wall of the support frame 2, and a lead screw is installed inside the inner groove 9. A drive motor 8 is fixed on the outer wall of the support frame 2, and the drive motor 8 is connected to the lead screw. A feed hopper 1 is installed on the side wall of the storage bin 7.
[0024] Reference Figure 3 The bottom of the transmission box 4 is provided with a transmission pipe 14. A sliding ring 16 is fixedly sleeved on the outer wall of the bottom end of the transmission pipe 14. A moving block 13 is fixedly connected to the side wall of the sliding ring 16. The moving block 13 is slidably connected to the inner wall of the moving frame 3. An L-shaped mounting hole 11 is opened on the inner wall of the moving frame 3. The moving block 13 is L-shaped and slidably adapted to the mounting hole 11. An internal screw 10 is horizontally installed inside the mounting hole 11. The internal screw 10 is threaded through the moving block 13. A motor connected to the internal screw 10 is fixedly installed inside the moving frame 3.
[0025] Reference Figure 4 A stirring rod 15 is rotatably mounted inside the transmission pipe 14, and a motor connected to the stirring rod 15 is mounted on the outer wall of the transmission pipe 14.
[0026] Working principle: The produced asphalt concrete is poured into the storage bin 7 through the feed hopper 1 for storage. A pump is installed inside the protective shell 6 fixedly installed above the storage bin 7. After the pump is started, it extracts the asphalt from the storage bin 7 and transports it to the transfer box 4 through the transfer hose 5 connected to the output end.
[0027] The bottom of the transmission box 4 is equipped with a transmission pipe 14. A sliding ring 16 is fixedly sleeved on the outer wall of the bottom end of the transmission pipe 14. A moving block 13 is connected to the side wall of the sliding ring 16, and the moving block 13 is slidably connected to the inner wall of the moving frame 3. An L-shaped mounting hole 11 is opened on the inner wall of the moving frame 3. An internal screw 10 is horizontally installed in the mounting hole 11. The internal screw 10 is threaded through the L-shaped moving block 13. A motor connected to the internal screw 10 is fixedly installed inside the moving frame 3. When the motor is started, it drives the internal screw 10 to rotate. Since the moving block 13 is threadedly connected to the internal screw 10 and can only move horizontally due to the restriction of the mounting hole 11, the rotation of the internal screw 10 will cause the moving block 13 to slide horizontally in the mounting hole 11, thereby driving the transmission pipe 14 to move horizontally within the moving frame 3.
[0028] An inner groove 9 is horizontally formed on the inner wall of the support frame 2, and a lead screw is installed in the inner groove 9. A drive motor 8 is fixed to the outer wall of the support frame 2 and connected to the lead screw. When the drive motor 8 is started, the lead screw rotates, and the moving frame 3 moves horizontally within the inner groove 9 through its threaded engagement with the lead screw, thereby adjusting the position of the transmission pipe 14 in the horizontal direction of the support frame 2. Through the dual horizontal movement of the moving frame 3 and the transmission pipe 14, the transmission pipe 14 can move horizontally over a wide range above the vehicle.
[0029] Once the transfer pipe 14 is moved to the appropriate position, asphalt is discharged from the transfer box 4 through the transfer pipe 14 into the vehicle carrying the asphalt below. During the asphalt concrete discharge process, the agitator 15, which is rotatably installed inside the transfer pipe 14, rotates continuously under the drive of a motor to agitate the asphalt, preventing the asphalt concrete from clogging the transfer pipe 14 and ensuring smooth asphalt discharge. Through the above steps, efficient and uniform feeding of asphalt concrete is achieved.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
