Description

Technical Field

[0001] This utility model relates to the field of concrete preparation technology, and in particular to a device for mixing fly ash and concrete raw materials. Background Technology

[0002] A fly ash and concrete raw material mixing unit is a specialized device for uniformly mixing fly ash with concrete raw materials (such as cement, sand, and gravel). Fly ash is a byproduct of coal-fired power plants and has potential cementitious activity, making it suitable as an admixture in concrete to improve its workability, strength, and durability.

[0003] In existing technologies, conventional fly ash and concrete raw material mixing devices discharge the mixed material through an internal pipeline structure after the mixing process is completed. Since the mixture of fly ash and concrete raw materials contains cement, sand, gravel, etc., discharging through the pipeline structure can easily cause blockage inside the pipeline, making it inconvenient to discharge the material quickly. Utility Model Content

[0004] In view of this, the present invention provides a fly ash and concrete raw material mixing device. The main technical problem to be solved is that the existing technology of discharging and feeding the mixed fly ash and concrete raw materials through the pipeline structure is prone to pipeline blockage, which is not convenient for rapid feeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fly ash and concrete raw material mixing device, comprising a mixing box, a support base disposed directly below the mixing box, a support plate fixedly connected to the upper surface of the support base, the mixing box rotatably connected to the inside of the support plate, a cylinder installed on the outer wall of the mixing box, a collar fixedly connected to the telescopic end of the cylinder, the collar rotatably connected to the outer wall of the mixing box, an ear plate fixedly connected to the bottom of the main body end of the cylinder, an ear seat fixedly connected to the upper surface of the support base, the ear plate rotatably connected to the outer wall of the ear seat, a sealing assembly installed at the bottom of the mixing box, the sealing assembly comprising a base plate and a sealing plate, a discharge port opened inside the mixing box, the sealing plate movably connected to the inside of the discharge port, the sealing plate fixedly connected to the upper surface of the base plate, a motor fixedly connected to the outer wall of the mixing box, the output end of the motor fixedly connected to the inside of the base plate, and an inclined plate fixedly connected to the lower surface of the mixing box, the inclined plate being disposed on the left side of the base plate.

[0006] By adopting the above technical solution, after the fly ash and concrete raw materials are mixed, the cylinder is started to drive the right side of the mixing box to lift and adjust, causing the mixing box to tilt. Then the motor is started to drive the bottom plate to rotate. The rotation of the bottom plate causes the sealing plate to rotate and move away from the inside of the discharge port, so that the mixed material inside the mixing box can be discharged from the discharge port. The tilting plate helps to guide the material to discharge, avoiding blockage during the material discharge process.

[0007] As a further description of the above technical solution: the mixing box is slidably connected to the inside of the mixing box, the cover plate is disposed above the inside of the mixing box, and a mixing component is installed inside the mixing box for mixing fly ash and concrete raw materials.

[0008] By adopting the above technical solution, the cover plate is slid to the right to remove its obstruction of the mixing box, and the fly ash and coagulation raw materials to be mixed are added into the interior of the mixing box. The mixing components then perform the mixing operation.

[0009] As a further description of the above technical solution: the mixing component includes a second motor, which is fixedly connected to the right side of the outer wall of the mixing chamber, and a stirring rod is fixedly connected to the output end of the second motor, which is rotatably connected inside the mixing chamber.

[0010] By adopting the above technical solution, motor 2 drives stirring rod 1 to rotate, and stirring rod 1 rotates to mix fly ash and concrete raw materials inside the mixing box.

[0012] By adopting the above technical solution, the rotation of the first stirring rod also drives the first gear to rotate, which in turn drives the second gear to rotate, thereby driving the second stirring rod to rotate. The second stirring rod and the first stirring rod rotate synchronously to fully mix the fly ash and coagulation raw materials.

[0013] As a further description of the above technical solution: a material conveying assembly is installed inside the support base, which is used to transport and discharge the mixed fly ash and concrete raw materials.

[0014] By adopting the above technical solution, the mixed fly ash and concrete raw materials are transported and discharged through the material conveying assembly.

[0015] As a further description of the above technical solution: the material conveying assembly includes a motor three, which is fixedly connected to one side of the outer wall of the support base, and the output end of the motor three is fixedly connected to a hub one.

[0016] By adopting the above technical solution, the first wheel hub is rotated by the third motor.

[0017] As a further description of the above technical solution: the first wheel hub is rotatably connected to the inside of the support base, the second wheel hub is rotatably connected to the inside of the support base, and a conveyor belt is rotatably connected to the outer wall of the first wheel hub and the second wheel hub.

[0018] By adopting the above technical solution, the rotation of hub one drives the rotation of the conveyor belt, causing hub two to rotate synchronously, and the rotation of the conveyor belt is used to transport the mixed materials.

[0020] By adopting the above technical solution, the conveyor belt drives the partition to move during rotation. The partition, combined with the baffle, divides the conveyor belt into multiple transport frame structures, thereby enabling the transport and unloading of the mixed materials.

[0021] By employing the above technical solution, the fly ash and concrete raw material mixing device of this utility model has at least the following beneficial effects:

By extending the telescopic end of the cylinder 3 upwards, the mixing box 1 can be tilted at an angle to facilitate the feeding of the mixed material. A sealing component 4 is installed at the bottom of the mixing box 1 to seal the mixture during the mixing process of fly ash and concrete raw materials. The sealing component 4 is sealed at the bottom of the mixing box 1 to prevent material spillage. The sealing component 4 includes a bottom plate 402 and a sealing plate 403. The mixing box 1 has an outlet 102. The sealing plate 403 is movably connected to the inside of the outlet 102 and is fixedly connected to the upper surface of the bottom plate 402.

An inclined plate 101 is fixedly connected to the lower surface of the mixing box 1. The inclined plate 101 is located on the left side of the bottom plate 402. The motor 401 drives the bottom plate 402 and the sealing plate 403 to rotate, causing the sealing plate 403 to disengage from the inside of the outlet 102. This allows the mixed material to be discharged through the outlet 102. The inclined plate 101 also blocks and guides the mixed material, assisting in the discharge of the mixed material.

[0031] A cover plate 103 is slidably connected inside the mixing chamber 1. The cover plate 103 is located on the upper part of the mixing chamber 1 and seals the upper part of the mixing chamber 1 during the mixing process of fly ash and concrete raw materials. A mixing assembly 5 is installed inside the mixing chamber 1. The mixing assembly 5 is used to mix fly ash and concrete raw materials. The mixing assembly 5 includes a second motor 501, which is fixedly connected to the right side of the outer wall of the mixing chamber 1. A stirring rod 502 is fixedly connected to the output end of the second motor 501. Rotary connection is made inside the mixing box 1. Gear 503 is fixedly connected to the end of stirring rod 502 away from motor 501. Stirring rod 504 is rotatably connected inside the mixing box 1. Gear 505 is fixedly connected to the outer wall of stirring rod 504. Gear 503 and gear 505 mesh. Through the meshing of gear 503 and gear 505, stirring rod 502 and stirring rod 504 can be made to rotate synchronously and in opposite directions, which helps to fully mix fly ash and concrete raw materials.

[0032] The support base 2 is equipped with a material conveying assembly 6, which is used to transport and discharge the mixed fly ash and concrete raw materials. The material conveying assembly 6 includes a motor 601, which is fixedly connected to one side of the outer wall of the support base 2. The output end of the motor 601 is fixedly connected to a hub 602, which is rotatably connected to the inside of the support base 2. A hub 603 is rotatably connected to the inside of the support base 2. A conveyor belt 604 is rotatably connected to the outer walls of hubs 602 and 603. The motor 601 drives hub 602 to rotate, causing the conveyor belt 604 and hub 603 to rotate synchronously. A partition 605 is fixedly connected to the outer wall of the conveyor belt 604, and a baffle 606 is fixedly connected to the outer wall of the conveyor belt 604. The baffles 606 are fixedly connected to both sides of the outer wall of the partition 605. The combination of multiple partitions 605 and baffles 606 on both sides, combined with the conveyor belt 604, forms a frame structure, which facilitates the transportation of the mixed materials.

[0033] Working principle: First, pull the cover plate 103 to the right to place the fly ash and concrete raw materials into the mixing box 1. Start the motor 2 501 to drive the stirring rod 1 502 and gear 1 503 to rotate. During the rotation of gear 1 503, the gear 2 505 and stirring rod 2 504 are driven to rotate, so that stirring rod 1 502 and stirring rod 2 504 rotate synchronously and in opposite directions. The rotation of stirring rod 1 502 and stirring rod 2 504 is used to stir and mix the fly ash and concrete raw materials. After the mixing is completed, the output of motor 2 501 stops. Rotating the cylinder 3 activates the cylinder, causing its extension end to extend upwards. This tilts the mixing chamber 1, causing it to rotate. Motor 401 then rotates the base plate 402 and sealing plate 403, disengaging the sealing plate 403 from the discharge port 102. The mixed material inside the mixing chamber 1 then exits through the discharge port 102. The tilting plate 101, positioned on the right side of the base plate 402, provides a limiting and blocking effect, preventing the mixed material from spilling out. The tilting plate 101 also guides the mixed material onto the transport conveyor. Inside section 604, the tilt angle of mixing box 1 can be adjusted by controlling the extension length of cylinder 3, and the angle at which motor 401 drives the bottom plate 402 and sealing plate 403 to rotate, thereby adjusting the feeding speed and amount of the mixed material. This feeding method solves the problem of blockage caused by the existing pipeline feeding structure, improving feeding efficiency. Before feeding, a collection frame is placed on the lower right side of the conveying assembly 6. Motor 601 is started to drive hub 602 to rotate, and the rotation of hub 602... The conveyor belt 604 and hub 603 rotate, which drives the baffle 606 and multiple partitions 605 to move. The rotation speed of the conveyor belt 604 is controlled by the speed of the motor 601 to ensure that the speed of the partitions 605 is matched with the speed of material feeding. During the feeding process, the mixed material falls between the partitions 605. The multiple partitions 605 divide the mixed material into portions, and the conveyor belt 604 drives the partitions 605 to move, so that the mixed material is transported to the collection box.
