Description

Technical Field

[0001] This utility model relates to the field of proportioning equipment technology, and in particular to an automatic proportioning device for recycled concrete. Background Technology

[0002] Recycled concrete refers to new concrete made by crushing, washing, and grading waste concrete blocks, mixing them with other aggregates in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel, and then adding cement and water. Recycled concrete production requires specific proportioning. Current automated proportioning devices for recycled concrete typically operate serially, weighing various raw materials sequentially. This method is time-consuming and cannot meet the needs of large-scale production. Utility Model Content

[0003] This invention provides an automatic proportioning device for recycled concrete, which solves the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic proportioning device for recycled concrete includes a base, a support pipe is provided at the top of the base, and a turntable is rotatably connected to the top of the support pipe.

[0006] A geared motor is installed at the bottom of the inside of the support tube, and the output end of the motor is connected to a rotating rod connected to the bottom of the turntable.

[0007] The top of the turntable has equidistant through slots, and the bottom of the through slots is connected to a first annular plate. A weighing sensor is installed on the top of the first annular plate. A hopper is placed inside the through slots, and a second annular plate is fixedly connected to the top of the weighing sensor on the surface of the hopper.

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

[0009] The bottom end of the hopper is connected to a discharge pipe, and the surface of the discharge pipe is connected to a first corrugated pipe. The bottom end of the first corrugated pipe is connected to a third annular plate, and the bottom end of the hopper is equipped with a cylinder connected to the top end of the third annular plate.

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

[0011] The surface of the cylinder is connected to a second bellows that is connected to the top of the third annular plate.

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

[0013] A motor is mounted on the surface of the hopper, and a stirring rod is connected to the output end of the motor.

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

[0015] The top of the base is provided with a sliding groove, and a slider is equidistantly connected in an annular shape inside the sliding groove. The top of the slider is connected to a support rod that is connected to the bottom of the turntable.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] In this invention, by opening multiple through slots at equal intervals in a ring on a turntable and installing hoppers, multiple raw materials can be weighed and proportioned simultaneously. During the rotation of the turntable, different hoppers can reach the discharge position in sequence to carry out continuous proportioning operations, which greatly improves production efficiency. At the same time, this structure reduces the manual weighing and proportioning process through an automated weighing and control system, reduces the impact of human error on proportioning accuracy, and also reduces the labor intensity of workers.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 2An automatic proportioning device for recycled concrete includes a base 1, a support pipe 2 at the top of the base 1, and a turntable 3 rotatably connected to the top of the support pipe 2; a reduction motor is installed at the bottom of the support pipe 2, and the output end of the motor is connected to a rotating rod 4 connected to the bottom of the turntable 3; the top of the turntable 3 has annularly spaced through slots 5, and the bottom of the through slots 5 is connected to a first annular plate 6, and a weighing sensor 7 is installed at the top of the first annular plate 6; a hopper 9 is placed inside the through slots 5, and a second annular plate 8, which is fixedly connected to the top of the weighing sensor 7, is fixedly connected to the surface of the hopper 9; a motor, a cylinder 13, and a weighing sensor are also included. Sensor 7 and motor 15 are connected to the controller, which controls how they are driven. The motor can rotate hopper 9 to a designated position for feeding. The weighing sensor 7 monitors the material and stops feeding once a certain weight is reached inside hopper 9. It can then be rotated to the top of the mixing equipment for unloading. This allows for the simultaneous weighing and proportioning of multiple raw materials. During the rotation of turntable 3, different hoppers 9 can sequentially reach the discharge position for continuous proportioning operations. This reduces the need for manual weighing and proportioning, minimizes the impact of human error on proportioning accuracy, and also reduces the labor intensity of workers.

[0024] Furthermore, the bottom end of the hopper 9 is connected to a discharge pipe 10, and the surface of the discharge pipe 10 is connected to a first corrugated pipe 11. The bottom end of the first corrugated pipe 11 is connected to a third annular plate 12. The bottom end of the hopper 9 is equipped with a cylinder 13 connected to the top end of the third annular plate 12. This cylinder 13 is used to move the third annular plate 12 and the first corrugated pipe 11, so that they can be moved to the feed inlet of the mixing equipment for easy feeding. This avoids the distance between the discharge pipe 10 at the bottom end of the hopper 9 and the feed inlet of the mixing equipment being too long, which would cause some coal ash powder to scatter around. The surface of the discharge pipe 10 is equipped with an electromagnetic gate valve.

[0025] Furthermore, the surface of the cylinder 13 is connected to a second bellows 14 that is connected to the top of the third annular plate 12. The second bellows 14 shields the telescopic end of the cylinder 13 to prevent dust and other particles from adhering to the surface of the cylinder 13 and causing wear on the cylinder 13.

[0026] Furthermore, a motor 15 is installed on the surface of the hopper 9, and a stirring rod is connected to the output end of the motor 15. This is to facilitate the rotation of the stirring rod inside the hopper 9 by the motor 15 during material feeding, so as to avoid material blockage inside the hopper.

[0027] Furthermore, a groove 16 is provided at the top of the base 1, and a slider 17 is equidistantly connected to the inner side of the groove 16. The top of the slider 17 is connected to a support rod 18 connected to the bottom of the turntable 3. The support rod 18, slider 17 and groove 16 are used to support the turntable 3.

[0028] 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.
