Description

Technical Field

[0001] This application relates to the technical field of concrete aggregate unloading equipment, specifically an adjustable-angle premixed concrete aggregate unloading equipment. Background Technology

[0002] In the concrete production process, aggregate unloading is a crucial step. Currently, many concrete aggregate conveying and unloading devices use screw conveyors for feeding, and this equipment is widely used in various construction projects. Screw conveyors use a rotating screw shaft to drive the aggregate flow, transporting it from the storage silo to the discharge port.

[0003] However, in actual use, especially when adding concrete aggregates, some problems are often encountered, affecting the flowability of the aggregates and the normal operation of the equipment. A typical problem is that the aggregates are difficult to flow smoothly in the discharge hopper, especially when the aggregate particle size is too uniform or the particle size difference is too large. The aggregates are prone to forming a "solidified" state, which prevents them from flowing freely. Specifically, the concrete aggregates accumulate in the discharge hopper, forming lumps or highly viscous materials, which obstructs the flow of aggregates and may even cause blockages. At this time, the equipment cannot discharge normally and manual intervention is often required. Long poles and other tools are used to stir the aggregates, forcing them to flow again and smoothly enter the conveying pipeline or discharge position. Manual stirring not only increases the labor intensity but also prolongs the construction time and reduces work efficiency.

[0004] Therefore, this application provides an adjustable-angle ready-mixed concrete aggregate unloading device to solve the above problems. Utility Model Content

[0005] This application provides an adjustable-angle premixed concrete aggregate unloading device, which aims to solve the problem mentioned in the background art where concrete aggregate accumulates in the unloading hopper, forming lumpy or highly viscous materials, resulting in obstructed aggregate flow.

[0006] To achieve the above objectives, this application provides the following technical solution: an adjustable-angle premixed concrete aggregate unloading device, including a screw conveyor and a drive motor fixedly installed at one end of the screw conveyor, wherein the end of the screw conveyor away from the drive motor is provided with a discharge port, the end of the screw conveyor close to the drive motor is provided with a feed hopper, and the lower end of the screw conveyor is provided with a base frame connected to the screw conveyor; The base frame is fixedly connected to the screw conveyor via a support frame, and the feed hopper is fixedly connected to the base frame via a reinforcing frame; A stirring mechanism is provided on the base frame; The stirring mechanism includes a fixed frame mounted on a base frame. A servo motor is mounted on the upper end of the fixed frame, and a connecting shaft is fixedly mounted on the output end of the servo motor. A positioning frame that fits onto the connecting shaft is mounted on the fixed frame. A protective shell is mounted on the upper end of the connecting shaft. A gear that fits onto the connecting shaft is mounted on the end of the protective shell near the connecting shaft. A shaft is rotatably connected to the end of the protective shell away from the connecting shaft. A transmission toothed belt that meshes with the gear and the shaft is installed inside the protective shell. A toothed ring is mounted on the lower end of the shaft. Through the transmission method of gears and transmission toothed belts, the transmission efficiency is high, and the stirring speed can be precisely controlled to ensure the consistency of the stirring effect.

[0007] Preferably, a fixing ring is sleeved at the lower end of the toothed ring, and a plurality of stirring rods are arranged in a ring on the fixing ring. The ring distribution design of the stirring rods can cover most of the area inside the feed hopper, improve the uniformity of stirring, and avoid the occurrence of stirring dead zones.

[0008] Preferably, a first reinforcing rod is symmetrically installed at one end of the protective shell near the connecting shaft, and the lower end of the first reinforcing rod is fixedly connected to the upper end of the positioning frame.

[0009] Preferably, a second reinforcing rod connected to the protective shell is symmetrically installed on the positioning frame, which improves the overall rigidity of the stirring mechanism, reduces vibration and noise, and ensures the stability of the stirring process.

[0010] Preferably, a sleeve is fitted onto the discharge port, a material distribution pipe is fixedly connected to the sleeve, a discharge pipe is fitted onto the end of the material distribution pipe away from the sleeve, an arm is symmetrically installed on the sleeve, a threaded seat corresponding to the arm is symmetrically installed on the discharge pipe, and a screw that is threadedly inserted into the threaded seat is fitted onto the end of the arm away from the sleeve. This improves the flexibility and applicability of the equipment, enabling it to adapt to different discharge scenarios, such as discharge points at different heights and positions.

[0011] Preferably, the toothed ring is located at the center of the feed hopper.

[0012] In this unloading equipment, the operator starts the servo motor, which drives the connecting shaft to rotate. The gear on the connecting shaft drives the shaft rod to rotate through the transmission belt, thereby causing the gear ring at the lower end of the shaft rod to rotate. This drives the shaft rod to break up the concrete aggregate in the "solidified" state, so that the subsequent concrete aggregate can enter the interior of the screw conveyor and be unloaded smoothly, avoiding manual intervention and reducing the labor intensity of the operators.

[0013] This unloading equipment, by setting up a material distribution pipe and a material discharge pipe at the discharge port, and relying on the screw and threaded connection of the screw seat, adjusts the position and angle of the material discharge pipe to achieve the function of adjusting the discharge angle, so that the equipment can be adjusted according to different unloading requirements.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] This embodiment provides an adjustable-angle premixed concrete aggregate unloading device, such as... Figure 1-4 As shown, the unloading device includes a screw conveyor 1 and a drive motor 11 fixedly installed at one end of the screw conveyor 1. The end of the screw conveyor 1 away from the drive motor 11 is provided with a discharge port 12. The end of the screw conveyor 1 close to the drive motor 11 is provided with a feed hopper 3. The lower end of the screw conveyor 1 is provided with a base frame 2 connected to the screw conveyor 1. The base frame 2 is fixedly connected to the screw conveyor 1 through the support frame 21, and the feed hopper 3 is fixedly connected to the base frame 2 through the reinforcing frame 22; A stirring mechanism 4 is provided on the base frame 2; The stirring mechanism 4 includes a fixed frame 41 fixedly mounted on the base frame 2. A servo motor 42 is provided at the upper end of the fixed frame 41. A connecting shaft 44 is fixedly mounted at the output end of the servo motor 42. A positioning frame 43 is mounted on the fixed frame 41 and sleeved with the connecting shaft 44. A protective shell 45 is provided at the upper end of the connecting shaft 44. A gear 441 is provided at the end of the protective shell 45 near the connecting shaft 44 and sleeved with the connecting shaft 44. A shaft 443 is rotatably connected at the end of the protective shell 45 away from the connecting shaft 44. A transmission toothed belt 442 is provided inside the protective shell 45 and meshes with the gear 441 and the shaft 443. A toothed ring 444 is provided at the lower end of the shaft 443. A fixing ring 445 is sleeved at the lower end of the toothed ring 444. Several stirring rods 446 are arranged in a ring on the fixing ring 445.

[0018] Specifically, the drive motor 11 starts, driving the spiral blades inside the screw conveyor 1 to rotate, conveying the pre-mixed concrete aggregate entering from the feed hopper 3 along the screw conveyor 1 to the discharge port 12. The base frame 2 supports the screw conveyor 1. At the same time, when the worker pours the concrete aggregate into the feed hopper 3, the worker starts the servo motor 42, driving the connecting shaft 44 to rotate. The gear 441 on the connecting shaft 44 drives the shaft 443 to rotate through the transmission belt 442, thereby causing the gear ring 444 at the lower end of the shaft 443 to rotate, thereby driving the shaft 443 to break the concrete aggregate in the "solidified" state, so that the subsequent concrete aggregate can enter the screw conveyor 1 and be discharged smoothly. The servo motor 42 always rotates slowly, mainly to prevent the concrete aggregate from being violently stirred and causing dust.

[0019] The protective shell 45 is symmetrically equipped with a first reinforcing rod 46 at one end near the connecting shaft 44, and the lower end of the first reinforcing rod 46 is fixedly connected to the upper end of the positioning frame 43.

[0020] More specifically, the first reinforcing rod 46 connects the protective shell 45 and the positioning frame 43 together, enhancing the connection strength between the protective shell 45 and the positioning frame 43, ensuring the relative position stability of the protective shell 45 and the positioning frame 43, and preventing shaking or displacement during the operation of the stirring mechanism 4.

[0021] A second reinforcing rod 47, which is connected to the protective shell 45, is symmetrically installed on the positioning frame 43.

[0022] Furthermore, the second reinforcing rod 47 further connects and reinforces the positioning frame 43 and the protective shell 45, enhancing the structural strength of the entire stirring mechanism 4 and making the connection between the components tighter.

[0023] A sleeve 5 is fitted onto the discharge port 12. A material distribution pipe 52 is fixedly connected to the sleeve 5. A discharge pipe 53 is fitted onto the end of the material distribution pipe 52 away from the sleeve 5. An arm 51 is symmetrically installed on the sleeve 5. A threaded seat 55 corresponding to the arm 51 is symmetrically installed on the discharge pipe 53. A screw 54 that is threaded into the threaded seat 55 is fitted onto the end of the arm 51 away from the sleeve 5.

[0024] It should be noted that, since the screw 54 is threadedly connected to the threaded seat 55, the rotation of the screw 54 will cause the feed pipe 53 to move relative to the distribution pipe 52, thereby adjusting the position and angle of the feed pipe 53 and realizing the function of adjusting the unloading angle. This allows the equipment to be adjusted according to different unloading requirements. The distribution pipe 52 is made of highly wear-resistant polyethylene material. Due to its flexibility, the feed pipe 53 can still be unaffected after the angle is adjusted.

[0025] The toothed ring 444 is located at the center of the feed hopper 3.

[0026] It is worth mentioning that the toothed ring 444 is located at the center of the feed hopper 3, which allows the stirring rod 446 to stir the aggregate in the feed hopper 3, breaking the "arch effect" of the concrete aggregate inside the feed hopper 3, so that the concrete aggregate can smoothly enter the pipe of the screw conveyor 1.

[0027] During use, when the worker pours the concrete aggregate into the feed hopper 3, the worker starts the servo motor 42, which drives the connecting shaft 44 to rotate. The gear 441 on the connecting shaft 44 drives the shaft 443 to rotate through the transmission belt 442, thereby causing the gear ring 444 at the lower end of the shaft 443 to rotate. The gear ring 444 is located at the center of the feed hopper 3, which allows the stirring rod 446 to stir the aggregate in the feed hopper 3, breaking the "arching effect" of the concrete aggregate inside the feed hopper 3, so that the concrete aggregate can smoothly enter the pipe of the screw conveyor 1.

[0028] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
