Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, and in particular to a novel concrete processing material distributor. Background Technology

[0002] In modern construction engineering and precast component production, concrete, as the most basic building material, relies heavily on the precision of its component proportions (such as cement, sand, aggregate, and various admixtures) for key performance indicators such as final strength, durability, and workability. Therefore, the material distribution or batching stage is a crucial upstream process for ensuring the quality of the final product in the concrete production process. The main function of the material distributor is to precisely dispense and feed various dry aggregates and powders according to a preset mix ratio, making it one of the core pieces of equipment in an automated concrete mixing plant.

[0003] Currently, conventional concrete production lines typically employ a material distribution system consisting of multiple parallel, independent storage silos, with each type of raw material (such as cement, fly ash, and sand and gravel of different particle sizes) occupying its own silo. Below each silo is an independent material discharge control mechanism, such as a pneumatic or hydraulically driven gate, butterfly valve, or a screw conveyor driven by an independent motor. During operation, the central control system activates these discharge mechanisms sequentially or in groups according to the formula, releasing different raw materials into the weighing conveyor belt or hopper below. After weighing, the materials are then uniformly transported to the main mixer. In this structure, the discharge and metering processes for each material are relatively independent, resulting in a single function.

[0004] However, the existing material distribution methods described above suffer from structural redundancy and low functional integration. Each storage silo's discharging mechanism operates independently, only capable of single opening / closing or conveying functions, failing to effectively premix multiple materials during the discharging process. Materials are simply stacked sequentially on the weighing device, resulting in significant stratification. This undoubtedly increases the workload of the subsequent main mixer, requiring longer mixing times to achieve uniformity and impacting production efficiency. Furthermore, multiple independent discharging mechanisms complicate the entire distribution system's structure and increase its footprint, raising both initial investment and maintenance costs. It also fails to integrate and synchronize the quantitative discharging and preliminary mixing of multiple materials, hindering the overall practicality and efficiency of the system. Therefore, a novel concrete processing material distributor is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel concrete dispensing device, aiming to improve existing dispensing methods. These methods suffer from low integration, independent dispensing mechanisms, and the inability to pre-mix materials, leading to material stratification, increased load and time on the main mixer, and reduced efficiency. Furthermore, they are complex in structure, costly, and fail to integrate quantitative dispensing and preliminary mixing functions.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel concrete processing material distributor, comprising a support plate, wherein a mixing tank is fixedly connected inside the support plate, and a material dispensing component is installed on the outer wall of the mixing tank;

[0007] The material distribution assembly includes a support box, the outer wall of which is fixedly connected to the inner wall of the mixing tank. A material distribution box is fixedly connected to the upper surface of the support box, and a discharge pipe is fixedly connected to the lower surface of the material distribution box. A motor is fixedly connected to one side of the outer wall of the mixing tank. A transmission rod is fixedly connected to the output end of the motor through the interior of the mixing tank. A bevel gear is fixedly connected to one end of the transmission rod through the support box. A stirring shaft is rotatably connected inside the support box. A bevel gear is fixedly connected to the outer wall of the stirring shaft, meshing with the tooth end of the bevel gear. A turntable is fixedly connected to the outer wall of the stirring shaft near the lower side of the support box. A discharge hole with the same size as the inner diameter of the discharge pipe is opened inside the turntable.

[0008] As a further description of the above technical solution:

[0009] The mixing tank has a limiting groove inside, and a rotating bucket is rotatably connected inside the mixing tank through the limiting groove.

[0010] As a further description of the above technical solution:

[0011] A second motor is fixedly connected to the lower surface of the support plate near the rotating bucket, and a spur gear is fixedly connected to the output end of the second motor.

[0012] As a further description of the above technical solution:

[0013] A gear ring is fixedly connected to the outer wall of the rotating bucket, and the gear ring meshes with the tooth end of a spur gear.

[0014] As a further description of the above technical solution:

[0015] A fixed cylinder is fixedly connected to the lower surface of the rotating bucket, and a limit rod is fixedly connected to the upper surface of the fixed cylinder.

[0016] As a further description of the above technical solution:

[0017] The support plate has a second limiting groove inside, and the upper end of the limiting rod is rotatably connected to the inner wall of the second limiting groove.

[0018] As a further description of the above technical solution:

[0019] The fixed cylinder is rotatably connected to an auger blade, with one end of the auger blade penetrating inside the fixed cylinder.

[0020] As a further description of the above technical solution:

[0021] A motor is fixedly connected to one side of the outer wall of the fixed cylinder, and the output end of the motor is fixedly connected to one end of the fixed cylinder.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, different raw materials are placed inside the dispensing box. At this time, the motor drives the bevel gear on the outer wall of the transmission rod to rotate inside the support box, thereby causing the bevel gear to mesh and rotate with the bevel gear. The bevel gear then drives the turntable on the outer wall of the stirring shaft to rotate. After the discharge hole inside the turntable is aligned with the discharge pipe diameter, the raw materials inside the dispensing box are quantitatively discharged. At the same time, the rotation of the stirring shaft can achieve the effect of mixing different raw materials, thereby improving the practicality of the equipment.

[0024] 2. In this utility model, the second motor drives the spur gear and the gear ring to mesh and rotate, thereby achieving the effect of limiting the rotating bucket on the inner wall of the limiting groove. At this time, the rotation of the rotating bucket facilitates the angle adjustment of the fixed cylinder. The fixed cylinder drives the limiting rod to rotate on the inner wall of the limiting groove, thereby achieving the effect of limiting rotation. Then, the third motor drives the auger blade to rotate, thereby facilitating the transfer of the mixed raw materials to different positions for feeding through the auger blade, thus improving the practicality of the equipment.

Detailed Implementation

[0031] 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.

[0032] Reference Figures 1-4 The present invention provides an embodiment of a new type of concrete processing material distributor, including a support plate 1, a mixing tank 2 for containing materials is installed inside the support plate 1 by a fixed connection, and a material distribution component for realizing quantitative feeding and preliminary mixing is installed on the outer wall of the mixing tank 2.

[0033] The material dispensing assembly specifically includes a support box 4 that serves as a carrier for the transmission mechanism. The outer wall of the support box 4 is securely connected to the inner wall of the mixing tank 2. A material dispensing box 9 for holding the raw materials to be mixed is fixedly connected to the upper surface of the support box 4. A discharge pipe 10 serving as a fixed discharge channel is vertically fixedly connected to the lower surface of the material dispensing box 9. A motor 3 serving as the main power source is fixedly installed on one side of the outer wall of the mixing tank 2. The output end of the motor 3 penetrates the inner wall of the mixing tank 2 and is fixedly connected to a horizontally arranged transmission rod 5. The other end of the transmission rod 5 extends and penetrates... The support box 4 has a bevel gear 6 fixedly connected to its end for transmitting power. Inside the support box 4, a vertically arranged stirring shaft 7 is rotatably connected via a bearing. On the outer wall of the stirring shaft 7, a bevel gear 8 is fixedly connected to mesh with the tooth end of the bevel gear 6 to transmit power, which is used to convert the horizontal rotation into the vertical rotation. On the outer wall of the stirring shaft 7, near the lower side of the support box 4, a turntable 11, which serves as a feeding control valve, is also fixedly connected. Inside the turntable 11, there is a feeding hole 12 with a size matching the inner diameter of the feeding pipe 10.

[0034] Specifically, motor 3 serves as the power source, driving the stirring shaft 7 to rotate via a transmission mechanism consisting of transmission rod 5, bevel gear 6, and bevel gear 8. The rotation of the stirring shaft 7 serves two purposes: firstly, it stirs and premixes the various raw materials inside the mixing tank 2; secondly, it simultaneously drives the turntable 11 at its lower end to rotate. By controlling the start and stop of motor 3, the discharge hole 12 on the turntable 11 is periodically aligned or staggered with the discharge pipe 10, thereby precisely controlling the material's descent. This achieves the effect of quantitatively discharging and initially mixing multiple materials, simplifying the equipment structure and improving processing efficiency.

[0035] Reference Figures 1-4 The mixing tank 2 has a circumferentially oriented limiting groove 13 inside, through which a rotating bucket 16 for receiving upper materials is rotatably connected. On the lower surface of the support plate 1, near the rotating bucket 16, a motor 14 serving as a rotation drive source is fixedly connected. The output end of the motor 14 is fixedly connected to a spur gear 15, which is a driving transmission component. A driven transmission component gear ring 17 is fixedly connected to the outer wall of the rotating bucket 16, meshing with the teeth of the spur gear 15 to form an angle-adjustable transmission system. A discharge channel is fixedly connected to the lower surface of the rotating bucket 16. A fixed cylinder 18 is provided, and a limiting rod 22 for auxiliary support and guidance is fixedly connected to its upper surface. Correspondingly, a limiting groove 21 is provided inside the support plate 1, and the upper end of the limiting rod 22 is rotatably connected to the inner wall of the limiting groove 21 to form an upper rotational support. A screw conveyor blade 20 for conveying materials is rotatably connected inside the fixed cylinder 18, and one end of the screw conveyor blade 20 is inserted through the inside of the fixed cylinder 18. On one side of the outer wall of the fixed cylinder 18, a motor 3 19 for driving material discharge is also independently fixedly connected, and the output end of the motor 3 19 is fixedly connected to one end of the screw conveyor blade 20.

[0036] Specifically, when the discharge position needs to be changed, the second motor 14 is started, and through the meshing transmission of the spur gear 15 and the gear ring 17, the entire rotating bucket 16, together with the fixed cylinder 18 below it, is driven to rotate stably in a circumferential direction under the joint guidance of the first limiting groove 13 and the second limiting groove 21, thereby achieving precise adjustment of the discharge angle. After the angle is positioned, the third motor 19 is started, driving the auger blade 20 inside the fixed cylinder 18 to rotate, forcibly and quantitatively conveying the material falling into the rotating bucket 16 to the designated position, realizing the directional control and active conveying function of the final discharge stage, greatly improving the adaptability and practicality of the equipment to different working conditions.

[0037] Working Principle: When using this device, firstly, different types of dry raw materials are placed inside the dispensing box 9 as needed. Then, the motor 3 is started, and its output drives the transmission rod 5 to rotate, which in turn drives the bevel gear 6 fixed on the transmission rod 5 to rotate synchronously. Since the bevel gear 6 meshes with the vertically arranged bevel gear 8, the rotation of the bevel gear 6 drives the bevel gear 8 to rotate, which in turn drives the stirring shaft 7 fixed to it to rotate around its own axis. The rotation of the stirring shaft 7 can, on the one hand, perform preliminary mixing of the various raw materials in the mixing tank 2, and on the other hand, it drives the turntable 11 at the lower end to rotate synchronously. When the turntable 11 rotates until the discharge hole 12 inside it is completely aligned with the diameter of the discharge pipe 10 below the dispensing box 9, the material falls into the mixing tank 2 below under the action of gravity through the discharge pipe 10 for mixing. By controlling the rotation time or number of revolutions of the motor 3, the quantitative feeding of the material can be achieved.

[0038] Secondly, when the final discharge direction needs to be adjusted, motor 14 is started, and its output drives spur gear 15 to rotate. Spur gear 15 meshes with gear ring 17 fixed on the outer wall of rotating bucket 16, thereby driving the entire rotating bucket 16 to rotate circumferentially within the limiting groove 13 inside mixing tank 2. During this process, the fixed cylinder 18 fixed to rotating bucket 16 and the limiting rod 22, which acts as a limit, also rotate synchronously, thereby achieving precise adjustment and positioning of the final discharge angle. After the discharge direction is adjusted to the correct position, motor 19 fixed on fixed cylinder 18 is started, and its output drives the auger blade 20 set inside fixed cylinder 18 to rotate. The rotating auger blade 20 forcibly conveys the mixed material falling from rotating bucket 16 along the axial direction of fixed cylinder 18 and discharges it from its end, thus completing the entire process of conveying and discharging the mixed material to different locations.

[0039] 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.
