Description

Technical Field

[0001] The present application relates to the technical field of asphalt concrete processing, and in particular to an asphalt concrete mixing device. Background Art

[0002] At present, in modern road construction and maintenance, asphalt concrete is the main pavement material, and its quality and production efficiency are directly related to the progress and quality of the project. Traditional asphalt concrete mixing equipment usually includes a tank, a stirring blade and a motor to drive the stirring blade to rotate. When mixing asphalt concrete, the material is added into the tank, the motor is started, and the stirring blade is driven to stir the material.

[0003] However, materials of different particle sizes may be mixed into concrete. During the mixing process, heavier materials may accumulate at the bottom of the tank due to their own gravity, resulting in poor mixing effect. Summary of the invention

[0004] In order to reduce bottom accumulation and improve mixing effect, the present application provides an asphalt concrete mixing equipment.

[0005] The present application provides an asphalt concrete mixing equipment, which adopts the following technical solution: An asphalt concrete mixing device, comprising: A tank body having a stirring chamber formed therein; A first stirring shaft rotates on the tank body and is provided with a first stirring blade; A driving assembly, disposed on the tank body and connected to the first stirring shaft, and used for driving the first stirring shaft to rotate; A second stirring shaft is slidably disposed on the tank body and is located on one side of the first stirring shaft, and is provided with a second disturbance blade, and the second disturbance blade drives the material to surge up and down; The disturbance mechanism is arranged on the tank body and connected to the second stirring shaft, and is used for driving the second stirring shaft to slide.

[0006] By adopting the above technical solution, first, the operator starts the driving component, which starts working and drives the first stirring shaft to rotate in the tank body, and the first stirring blade set on the first stirring shaft rotates accordingly to start preliminary stirring of the asphalt concrete material in the tank body; as the first stirring shaft rotates, the material in the tank body begins to be sheared, squeezed and tumbled, achieving basic uniform mixing; at the same time, the disturbance mechanism starts working, which drives the second stirring shaft to slide along a certain trajectory in the tank body; the second disturbance blade set on the second stirring shaft continuously changes the position and state of the material during the sliding process, and in particular can drive the material to surge up and down, further enhancing the stirring effect; the operator can optimize the stirring process according to the stirring requirements by adjusting the working parameters of the driving component and the disturbance mechanism (such as rotation speed, sliding speed, etc.) to ensure that the material reaches the expected uniformity and quality; when the material in the tank body meets the stirring requirements, the operator stops the driving component and the disturbance mechanism and turns off the equipment; at this time, the asphalt concrete material in the tank body has been fully mixed and is ready for the next step of production or processing.

[0007] Through the synergistic effect of the first stirring shaft and the second stirring shaft, the equipment can achieve full and uniform mixing of materials in a shorter time, thereby improving the mixing efficiency; the sliding of the second stirring shaft and the tumbling effect of the second disturbance blade enable the materials to be more fully mixed and dispersed in the tank body, thus avoiding the problems of local material accumulation and uneven mixing and improving the mixing quality; the design of the equipment allows adjustment of the working parameters of the drive components and the disturbance mechanism, thus being able to adapt to the mixing requirements of asphalt concrete materials of different types and specifications; the equipment adopts an automated control method, and the operator only needs to use a simple operating interface to start, stop and adjust the parameters of the equipment, thereby reducing the difficulty of operation and labor intensity.

[0008] Optionally, the disturbance mechanism comprises: A linkage ring, disposed on the first stirring shaft and slidably connected to the second stirring shaft; The disturbance block is arranged at the bottom of the tank body, forms a wave surface, and abuts against one end of the second stirring shaft to drive the second stirring shaft to slide up and down.

[0009] By adopting the above technical solution, as the first stirring shaft continues to rotate, the linkage ring drives the second stirring shaft to rotate; as the second stirring shaft rotates, when one end of the second stirring shaft contacts the wave surface of the disturbance block, due to the irregular shape of the wave surface, the second stirring shaft will be subjected to an upward or downward force, and thus begins to slide up and down; as the first stirring shaft continues to rotate, the linkage ring continuously changes its relative position with the second stirring shaft, causing the second stirring shaft to continuously slide up and down under the guidance of the wave surface of the disturbance block; the second disturbance blade on the second stirring shaft continuously changes the position and state of the material during the sliding process, and in particular can drive the material to surge up and down, thereby further enhancing the stirring effect.

[0010] Optionally, the disturbance mechanism further comprises: A fixed rod is rotatably connected to the linkage ring, and the second stirring shaft is slidably connected to the fixed rod; The rotating assembly is connected to the fixing rod and is used to drive the fixing rod to rotate.

[0011] By adopting the above technical solution, the first stirring shaft drives the fixed rod to rotate around the first stirring shaft through the linkage ring during the rotation process, and the fixed rod drives the second stirring shaft to rotate, so that the second stirring shaft abuts against the wave surface of the disturbance block, and the second stirring shaft and the fixed rod slide relative to each other; the rotating assembly drives the fixed rod and the second stirring shaft to rotate, thereby increasing the disturbance to the asphalt concrete, and at the same time accelerating the rate and efficiency of the bottom material surging upward, so that the mixing of the asphalt concrete is more uniform and sufficient, and the mixing effect is improved.

[0012] Optionally, a return spring is provided on the fixing rod, and the return spring is connected to the second stirring shaft and is used to push the second stirring shaft to approach the disturbance block.

[0013] By adopting the above technical solution and setting the reset spring, the second stirring shaft is always in contact with the disturbance block, so that the up and down disturbance effect of the second stirring shaft is maintained, thereby improving the stirring of the asphalt concrete.

[0014] Optionally, the rotating assembly comprises: A fixed gear ring is arranged on the top wall of the tank body; a first transmission gear meshing with the fixed gear ring, being rotationally connected to the first stirring shaft and rotating along with the first stirring shaft; A second transmission gear, coaxially connected to the first transmission gear; The third transmission gear is connected to the fixing rod and is transmission-connected to the second transmission gear through a transmission member.

[0015] By adopting the above technical solution, when the first stirring shaft drives the first transmission gear to rotate, the first transmission gear rotates along the fixed gear ring, the first transmission gear drives the second transmission gear to rotate, the second transmission gear drives the third transmission gear to rotate through the transmission member, the third transmission gear drives the fixed rod to rotate, and the fixed rod drives the second stirring shaft to rotate, thereby increasing the disturbance to the asphalt concrete and improving the stirring effect.

[0016] Optionally, a right-angle portion is provided on the wave surface, so that the second stirring shaft suddenly drops after rising.

[0017] By adopting the above technical solution, the right-angle portion is set so that the second stirring shaft suddenly loses support when sliding in the vertical direction. With the help of the return spring, the second stirring shaft vibrates back and forth, increasing the turbulence of the material, further improving the stirring effect, and making the asphalt concrete mix more evenly.

[0018] Optionally, the second disturbance blade is a spiral blade, and lifts the material as it rotates.

[0019] By adopting the above technical solution and setting the spiral blades, the disturbance blades can lift the materials during the rotation process, so that the bottom materials can rise quickly and the mixing effect can be increased.

[0020] Optionally, the cross-sectional area of ​​the second disturbance blade at one end close to the bottom wall of the tank body is larger than the cross-sectional area of ​​the second disturbance blade at one end close to the driving assembly.

[0021] By adopting the above technical solution, the disturbance blades are arranged to be larger at the bottom and smaller at the top, so as to increase the disturbance to the bottom material, and make the bottom material rise over a large range, thereby achieving rapid mixing of the material.

[0022] Optionally, a guide portion is provided at the bottom of the tank body, and the guide portion is conical and extends to the disturbance block.

[0023] By adopting the above technical solution and setting the guide part, the material is moved closer to the disturbance blade, which reduces the accumulation of the middle material and facilitates the disturbance blade to disturb the bottom material in the whole range, so that the mixing effect can be maintained.

[0024] Optionally, a third stirring shaft is slidably connected to the first stirring shaft, and the first stirring blade is arranged on the third stirring shaft; a reciprocating component is arranged on the third stirring shaft, and the reciprocating component includes: A reciprocating screw rod is arranged on the guide portion; A sliding sleeve slides on the guide portion, and one end of the sliding sleeve is threadedly connected to the reciprocating screw, and the other end is fixedly connected to the third stirring shaft.

[0025] By adopting the above technical solution, when the first stirring shaft rotates, the first stirring shaft drives the sliding sleeve to rotate, and the sliding sleeve slides back and forth through the reciprocating screw, so that the third stirring shaft slides back and forth up and down, and cooperates with the reverse sliding of the second stirring shaft to increase the collision between materials, thereby enhancing the disturbance in the tank body and increasing the mixing effect.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the synergistic effect of the first stirring shaft and the second stirring shaft, the equipment can achieve full and uniform mixing of materials in a relatively short time, thus improving the mixing efficiency; the sliding of the second stirring shaft and the tumbling effect of the second disturbance blade enable the materials to be more fully mixed and dispersed in the tank, thus avoiding the problems of local material accumulation and uneven mixing, and improving the mixing quality; the design of the equipment allows the adjustment of the working parameters of the drive components and the disturbance mechanism, thus being able to adapt to the mixing requirements of asphalt concrete materials of different types and specifications; the equipment adopts an automatic control mode, and the operator can start, stop and adjust the parameters of the equipment through a simple operation interface, thus reducing the difficulty of operation and labor intensity; 2. During the rotation process, the first stirring shaft drives the fixed rod to rotate around the first stirring shaft through the linkage ring, and the fixed rod drives the second stirring shaft to rotate, so that the second stirring shaft abuts against the wave surface of the disturbance block, and the second stirring shaft and the fixed rod slide relative to each other; the rotating assembly drives the fixed rod and the second stirring shaft to rotate, increasing the disturbance to the asphalt concrete, and at the same time speeding up the rate and efficiency of the bottom material surging upward, so that the asphalt concrete is stirred more evenly and fully, and the stirring effect is improved; 3. The right-angled part makes the second stirring shaft suddenly lose support when sliding in the vertical direction. With the help of the return spring, the second stirring shaft vibrates back and forth, increasing the surging of the material, further improving the stirring effect, and making the asphalt concrete mix more evenly. 4. When the first stirring shaft rotates, the first stirring shaft drives the sliding sleeve to rotate. The sliding sleeve slides back and forth through the reciprocating screw, causing the third stirring shaft to slide back and forth up and down, cooperating with the reverse sliding of the second stirring shaft, increasing the collision between the materials, enhancing the disturbance in the tank, and increasing the mixing effect.

[0037] The implementation principle of an asphalt concrete mixing device in an embodiment of the present application is as follows: the asphalt concrete mixing device is in a stationary state, and the mixing chamber 110 in the tank body 100 is empty or contains raw materials to be mixed; the first mixing shaft 200, the second mixing shaft 400 and the third mixing shaft 770 are all in the initial position; the return spring 750 remains in a compressed state, pushing the second mixing shaft 400 close to the bottom wall of the tank body 100, and the reciprocating screw 781 and the sliding sleeve 782 are in an initial threaded connection state; when the drive motor is started, it starts to drive the first mixing shaft 200 to rotate, and the first mixing blade 300 on the first mixing shaft 200 rotates accordingly, and starts to mix the raw materials in the mixing chamber 110; while the first mixing shaft 200 rotates, due to the meshing action of the connecting rod 790 and the fixed gear ring 741, it also drives the first transmission gear 742 revolves along the fixed gear ring 741; the first transmission gear 742 drives the second transmission gear 743 to rotate, the second transmission gear 743 drives the third transmission gear 744 to rotate through the synchronous belt, the third transmission gear 744 drives the fixed rod 730 to rotate, the fixed rod 730 drives the second stirring shaft 400 to rotate, and the second stirring shaft 400 revolves along the connection, so that the second stirring shaft 400 slides up and down along the wave surface 721, and the wave surface 721 generates an up and down disturbing force on the second stirring shaft 400.
