Technical Field

[0001] This utility model relates to the field of low-carbon concrete production technology, specifically to a low-carbon concrete proportioning and feeding mechanism. Background Technology

[0002] Low-carbon concrete reduces the amount of cement used in its production process by incorporating large amounts of mineral slag and construction waste as aggregates, thereby reducing the consumption of natural sand and gravel resources and indirectly reducing emissions of excessive dust and gas from over-exploitation. Low-carbon concrete requires a feeding mechanism during the mix design.

[0003] In related technologies, the discharge port of the low-carbon concrete proportioning and feeding mechanism is usually fixed, which causes the discharged material to easily accumulate, thus affecting the speed of material proportioning uniformity. Moreover, when the amount of raw materials is too large, the discharge port is prone to blockage. Although in the prior art, the raw materials can be stably fed by setting a stirring structure in the discharge port, the stirring structure will occupy part of the discharge space, affecting the discharge speed and increasing maintenance costs. Based on this, this application proposes a low-carbon concrete proportioning and feeding mechanism. Utility Model Content

[0021] 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.

[0022] This utility model provides an embodiment: Please refer to Figures 1-5 The low-carbon concrete proportioning and feeding mechanism includes a screw conveyor structure, a discharge structure, and a limiting structure. The screw conveyor structure includes a shell 1, a feed hopper 2 at the lower end of the shell 1, a screw conveyor shaft 14 in the middle of the inner cavity of the shell 1, a servo motor 4 at the lower end of the shell 1, and the screw conveyor shaft 14 is driven by the servo motor 4. A slot 15 is provided at the bottom of the upper end of the shell 1. When the screw conveyor structure is working, the raw materials for low-carbon concrete production enter the inner cavity of the shell 1 through the feed hopper 2. The servo motor 4 drives the screw conveyor shaft 14 to rotate, and the screw conveyor shaft 14 can convey the raw materials. Under the action of the screw conveyor shaft 14, the raw materials are conveyed to the slot 15.

[0023] The discharge structure is located at the high end of the screw conveyor structure. The discharge structure includes a turntable 8 movably connected to the end of the outer casing 1 and a drive structure 7. The turntable 8 is driven by the drive structure 7. Figures 1 to 3 As shown, the outer wall of the turntable 8 has a toothed groove. The output shaft of the drive structure 7 is connected to a rotating shaft 11. The rotating shaft 11 is connected to the housing 1 through a bearing 13. The rotating shaft 11 and the housing 1 are in a movable connection state. The other end of the rotating shaft 11 is connected to a gear 10. The gear 10 meshes with the toothed groove. When the drive structure 7 rotates, it can drive the rotating shaft 11 connected to it to rotate. The rotating shaft 11 can drive the turntable 8 to rotate through the gear 10 connected to it. The drive structure 7 can be a servo motor in the prior art.

[0024] A double-headed hydraulic telescopic rod 9 is connected to the middle of the turntable 8. A connecting rod 16 is connected to the end of the output shaft of the double-headed hydraulic telescopic rod 9. The turntable 8 has a slot 18 that matches the connecting rod 16. The output shaft of the double-headed hydraulic telescopic rod 9 is movably connected to the slot 18, allowing the connecting rod 16 to engage with the slot 18. Under the action of the double-headed hydraulic telescopic rod 9, the connecting rod 16 can engage or disengage from the slot 18. Two semi-circular rings 5 ​​are fixedly connected to the inner side of the connecting rod 16. When the flat parts of the semicircular rings 1 and 5 come into contact, a shielding tube can be formed. The discharge tube is located below the tube. The slot 15 is located in the inner cavity of the shielding tube. The shielding tube blocks the slot 15. The discharge tube is provided below the shielding tube. Both the shielding tube and the discharge tube are separate structures. The discharge tube includes two semicircular rings 2 and 3. The semicircular rings 2 and 3 are connected to the semicircular rings 1 and 5. The inner diameter of the discharge tube is smaller than the width and height of the slot 15. The size of the discharge tube can be set according to the requirements and is not limited here.

[0025] As described above, the raw material at slot 15 can enter the discharge pipe and be discharged through it. During the discharge process, the drive structure 7, via the turntable 8 and the double-headed hydraulic telescopic rod 9, can drive the shielding pipe to rotate. The shielding pipe drives the discharge pipe to rotate, and under the action of centrifugal force, the discharge pipe speed can be accelerated, reducing blockage and accumulation. Furthermore, the material drop position can be changed, thus avoiding material accumulation and facilitating the proportioning of low-carbon concrete. When the double-headed hydraulic telescopic rod 9 extends and retracts, it can change the position of semi-circular ring 5. When semi-circular ring 5 moves, it can drive semi-circular ring 3 to move, changing the distance between the two semi-circular rings 3. When the discharge pipe is blocked, the separation of the two semi-circular rings 3 increases the size of the discharge pipe, allowing the blocked material to fall off under gravity, achieving rapid cleaning of the discharge pipe. Furthermore, when semi-circular ring 5 resets, the output shaft of the double-headed hydraulic telescopic rod 9 is locked to the cylinder, and the length of the double-headed hydraulic telescopic rod 9 is fixed.

[0026] In addition, buffer pads are fixedly connected to the inner sides of both semicircular ring 5 and semicircular ring 3. The buffer pads can be made of rubber. The buffer pads can reduce the impact force when the two semicircular rings 5 ​​and 3 come into contact, and improve the sealing performance. The buffer pads can be made of rubber.

[0027] The limiting structure includes a limiting hydraulic telescopic rod 12 fixedly connected to the outer shell 1 and a limiting ring 6 connected to the end of the output shaft of the limiting hydraulic telescopic rod 12. A connecting ring 17 is movably connected to the inner side of the limiting ring 6. The connecting ring 17 is adapted to the shielding tube. An anti-slip pad is fixedly connected to the inner wall of the connecting ring 17. The anti-slip pad can be made of rubber. The limiting ring 6 is located on the side away from the turntable 8 at the connection between the discharge pipe and the shielding tube. Under the action of the limiting hydraulic telescopic rod 12, the connecting ring 17 can be sleeved on the outer ring of the shielding tube or separated from the shielding tube. When the connecting ring 17 is sleeved on the outer ring of the shielding tube, the limiting ring 6 and the connecting ring 17 can support the shielding tube and improve the stability of the shielding tube. When the connecting ring 17 is separated from the shielding tube, it facilitates the movement of the semi-circular ring 5.

[0028] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0029] In summary: When this low-carbon concrete proportioning and feeding mechanism is in use, it utilizes a screw conveyor structure to transport the raw materials used in the low-carbon concrete preparation. The raw materials enter the discharge pipe through the slot 15 and are discharged through the discharge pipe. During the discharge process, the drive structure 7 drives the turntable 8 to rotate, the turntable 8 drives the connecting rod 16 connected to it to rotate, the connecting rod 16 drives the semi-circular ring 5 to rotate, and the semi-circular ring 5 drives the semi-circular ring 3 to rotate, thereby causing the discharge pipe to rotate. This can accelerate the material discharge speed and expand the material drop range, avoid material accumulation, and facilitate material mixing. This can improve the speed of uniform mixing of raw materials for low-carbon concrete preparation. Furthermore, when the discharge pipe becomes jammed, the double-headed hydraulic telescopic rod 9 extends. The double-headed hydraulic telescopic rod 9 drives the semi-circular ring 3 to move through the semi-circular ring 5, increasing the distance between the two semi-circular rings 3, thereby allowing the blocked material to be discharged quickly and achieving rapid cleaning of the discharge pipe.
