Description

Technical Field

[0001] This utility model relates to the technical field of concrete mixing equipment, and in particular to an integrated concrete mixing and conveying equipment. Background Technology

[0002] Concrete is a composite material formed by binding fine and coarse aggregates with cement and allowing it to harden over time. Historically, lime-based cement, such as lime paste, was most common, but hydraulic cements, such as calcium aluminate cement or silicate cement, are sometimes used. When aggregates are mixed with dry silicate cement and water, the mixture forms a paste that is easy to pour and shape. Cement reacts with water and other components to form a rigid matrix that binds these materials together, creating a durable, rock-like material with numerous applications. Admixtures are typically added to the mixture to improve the physical properties of the paste and the final product.

[0003] Foamed concrete refers to lightweight porous concrete made by preparing foam from a foaming agent aqueous solution using physical methods, and then adding the foam to a slurry made of cement, aggregates, admixtures, additives, and water. Chinese Patent Publication No. CN120307466A discloses a "concrete mixing equipment", which, through the setting of mixing components and force lifting components, only requires the mixing structure to perform the mixing action on the concrete, and can complete the cyclic mixing process of the concrete from the bottom, through the highest point, then pushed to the edge and then descending back to the bottom. It uses the original structure inside the mixing tank to achieve the purpose of cyclic mixing of foamed concrete, thereby reducing the equipment cost and operating cost required for longitudinal mixing of concrete batching. At the same time, it moves foam into the interior of the concrete from multiple positions in the middle and edges, accelerating the speed at which the foam is mixed into the interior of the concrete.

[0004] However, in actual use, powdery raw materials are easily blown into the air during concrete mixing, polluting the environment and affecting the health of operators. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency of powdered raw materials to fly and pollute the environment, affecting the health of operators, and to propose an integrated concrete mixing and conveying equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design an integrated concrete mixing and conveying device, including a mixing tank, a driving device on one side of the mixing tank, and a base at the lower end of both the driving device and the mixing tank. Two cooperating mixing rollers are installed inside the mixing tank, and the driving device is poweredly connected to the two mixing rollers. The mixing tank has a feed inlet and a discharge outlet, and the discharge outlet is connected to a conveyor via a hopper. A sealing cover is installed on the feed inlet, and a driving structure that cooperates with the sealing cover is installed on the mixing tank.

[0007] Furthermore, the drive structure includes a motor mounted on the mixing tank and a lead screw fixedly connected to the motor output shaft, and a drive block threadedly connected to the lead screw is provided on the sealing cover.

[0008] Furthermore, the mixing tank is provided with two guide frames that cooperate with the sealing cover, and the two sides of the sealing cover are slidably connected to the guide frames.

[0009] Furthermore, a guide block is fixedly provided on the guide frame, and a clamping component is provided between the guide block and the sealing cover.

[0010] Furthermore, the clamping assembly includes a mounting frame fixedly disposed on the sealing cover corresponding to the guide block. The guide block is a wedge-shaped block with an inclined surface. A roller that rotatably engages with the inclined surface of the guide block is rotatably disposed within the mounting frame. Furthermore, a bearing seat rotatably connected to the lead screw is fixedly disposed on the mixing tank. Bellows covers are disposed on both sides of the drive block, and the two bellows covers are respectively connected to the bearing seat and the motor.

[0011] The integrated concrete mixing and conveying equipment proposed in this utility model has the following advantages: In this utility model, a sealing cap is used to cover the feed inlet to prevent dust from spreading and polluting the environment during mixing. A clamping component is used to ensure that the sealing cap and the feed inlet are tightly abutted together, further preventing dust from spreading. Secondly, in this invention, by setting a conveyor at the discharge port, the mixed concrete can be discharged in a timely manner and transported to the subsequent processing position, which is convenient for making foam bricks, etc. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-4 An integrated concrete mixing and conveying device includes a mixing tank 1, a driving device 2 on one side of the mixing tank 1, and a base 3 at the lower end of both the driving device 2 and the mixing tank 1. Two cooperating mixing rollers 4 are installed inside the mixing tank 1, and the driving device 2 is poweredly connected to the two mixing rollers 4. The mixing tank 1 has a feed inlet and a discharge outlet. The discharge outlet is connected to a conveyor 5 via a hopper. A sealing cover 6 is installed on the feed inlet, and a driving structure 7 that cooperates with the sealing cover 6 is installed on the mixing tank 1.

[0016] In this invention, the feed inlet is blocked by the drive structure 7 and the sealing cover 6 to prevent dust from spreading and polluting the environment during mixing. The drive structure 7 can also drive the sealing cover 6 to move and expose part of the feed inlet, making it convenient to add raw materials to the mixing tank 1.

[0017] Furthermore, in this embodiment, the drive structure 7 includes a motor 71 mounted on the mixing tank 1 and a lead screw 72 fixedly connected to the output shaft of the motor 71. The sealing cover 6 is provided with a drive block 73 threadedly connected to the lead screw 72. The motor 71 drives the lead screw 72 to rotate, and the rotation of the lead screw 72 pushes the drive block 73 and the sealing cover 6 to move. Controlling the position of the sealing cover 6 facilitates blocking or partially exposing the feed inlet for easy feeding.

[0018] Furthermore, in this embodiment, the mixing tank 1 is provided with two guide frames 74 that cooperate with the sealing cover 6, and the two sides of the sealing cover 6 are slidably connected to the guide frames 74. By setting the guide frames 74, the movement trajectory of the sealing cover 6 is restricted, preventing it from deviating from the trajectory and causing excessive force on the drive block 73, resulting in deformation.

[0019] It should be noted that, in this embodiment, a guide block 75 is fixedly provided on the guide frame 74, and a pressing component 76 is provided between the guide block 75 and the sealing cover 6. In some embodiments, a sealing ring, such as wear-resistant rubber or a rubber ring with a smooth lower surface, may be provided on the sealing cover 6.

[0020] Furthermore, in some embodiments, the clamping assembly 76 includes a mounting frame 761 fixedly disposed on the sealing cover 6 corresponding to the guide block 75. The guide block 75 is a wedge-shaped block with an inclined surface. A roller 762 that cooperates with the inclined surface of the guide block 75 is rotatably disposed inside the mounting frame 761. When the sealing cover 6 moves to block the feed inlet, the inclined surface of the guide block 75 cooperates with the roller 762 to apply a downward force to the sealing cover 6, ensuring that the sealing cover 6 is in close contact with the feed inlet and preventing dust from spreading and polluting the environment due to excessive gaps between the sealing cover 6 and the feed inlet.

[0021] More specifically, in this embodiment, a bearing seat 8 is fixedly installed on the mixing tank 1 and rotatably connected to the lead screw 72. Both sides of the drive block 73 are provided with bellows covers 9. The two bellows covers 9 are respectively connected to the bearing seat 8 and the motor 71. By setting the bellows covers 9 to shield the lead screw 72, dust adhering to the lead screw 72 is prevented from affecting its use.

[0022] Working method: During operation, raw materials are poured into the mixing tank 1 through the feed inlet, and the mixing roller 4 is driven by the drive device 2 to rotate and mix the raw materials. The mixed concrete is discharged from the discharge outlet through the conveyor 5. After the raw materials are loaded, the motor 71 drives the lead screw 72 to rotate. The rotation of the lead screw 72 pushes the drive block 73 and the sealing cover 6 to move and block the feed inlet. The inclined surface of the guide block 75 cooperates with the roller 762 to apply a downward force to the sealing cover 6, ensuring that the sealing cover 6 is in close contact with the feed inlet and preventing dust from spreading and polluting the environment due to excessive gaps between the sealing cover 6 and the feed inlet.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
