Description

Technical Field

[0001] The utility model belongs to the technical field of flow scales, and in particular relates to a reduction-type electronic flow scale. Background Art

[0002] Electronic flow scales are widely used in modern industrial production, such as grain and feed processing, steelmaking, and cement production. They primarily measure the weight of bulk solids during continuous material transportation, making their weighing accuracy crucial. Furthermore, production processes require rapid and continuous weighing of materials. Subtraction-type electronic flow scales are ideal for continuous and accurate weighing of various bulk solids. Utilizing high-precision sensors, they offer fast response times and high resolution, making them particularly convenient for rapid weighing of bulk solids.

[0003] Common flow scales are mostly electronically controlled pneumatic flow scales. This type of flow scale has high requirements for the gas source, and its manufacturing cost and the cost of subsequent use, maintenance and repair are high. In addition, there are bad and moist parts in the weighed grain. Such grains are easy to adhere to the inner wall of the weighing hopper after weighing. If too much adhesion occurs, it will cause certain errors in the weighing results and cannot meet the working requirements of the flow scale. For this reason, a reduction-type electronic flow scale is proposed. Summary of the Invention

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a reduction-type electronic flow scale, comprising:

[0005] A bracket, wherein a weighing bucket is installed on the inner upper part of the bracket, an oil cylinder is installed on the upper part of the weighing bucket, and a weight sensor is installed on the upper right part of the weighing bucket;

[0006] The driving motor is installed at the lower right side of the weighing bucket. The top of the weighing bucket is equipped with a feed hole arc door, the lower part of the weighing bucket is equipped with a discharge port arc door, and the bottom end of the weighing bucket is provided with a discharge port;

[0007] The weight rack is installed in the middle position of the front part of the weighing bucket, and mounting seats are installed on the left and right sides of the interior of the rack.

[0008] Furthermore, the arc door of the feed hole is fixedly connected to the output shaft of the oil cylinder, and the arc door of the discharge port is fixedly connected to the output shaft of the drive motor. The structure is simple and convenient and has extremely high stability. The oil cylinder can also adjust the stroke, so that the flow control is more precise and convenient for electrical control. At the same time, the discharge port uses a drive motor to control the arc door, which can expand the adjustment range.

[0009] Furthermore, an L-shaped connecting frame is installed in the middle of the outer side of the mounting seat, a stepper motor is installed in the middle of the L-shaped connecting frame through an angle code, and the rotor of the stepper motor is coaxially fixedly connected to the worm.

[0010] Furthermore, the inner upper portion of the L-shaped connecting frame is movably connected to a worm wheel through a bearing, the worm wheel is engaged with the worm, and the outer side of the worm wheel is fixedly connected to a swing arm.

[0011] Furthermore, a shaft column is installed in the middle position of the top of the mounting seat, an inserted shaft is inserted inside the shaft column, and a hinge seat is installed on the top of the inserted shaft. The inside of the hinge seat is movably connected with the corresponding position of the outside of the swing arm through a rotating shaft. The worm is driven to rotate by a stepping motor, so that the swing arm can swing in a fan shape with the cooperation of the worm gear, and the grain material inside the symmetrical weighing bucket can be scattered and dried.

[0012] Furthermore, a heating plate is installed at the bottom end of the swing arm, the shape of the swing arm is L-shaped, and the bending part of the swing arm is provided with a conical sealing sleeve to prevent the material inside the weighing bucket from spilling out during the swinging motion. Beneficial effects

[0013] 1. This reduction-type electronic flow scale adopts the principle of weight loss weighing. When the material is below the lower limit, the material is quickly replenished, and when it reaches the upper limit, the replenishment is stopped. The material is discharged continuously. The material is adjusted by the hydraulic cylinder and the drive motor to drive the arc door. When it is less than the fixed quantity, the discharge port gradually increases, and when it is greater than the fixed quantity, the discharge port gradually decreases, so as to achieve the purpose of controlling the flow. The structure is simple and convenient, with extremely high stability. The hydraulic cylinder can also adjust the stroke, so that the flow control is more precise and convenient for electrical control. At the same time, the discharge port adopts the drive motor to control the arc door, which can expand the adjustment range and continuously control the size of the flow. It runs smoothly and has good stability. The use of drive motor control avoids the installation of the power device inside the equipment, which is easy to install and more convenient to maintain.

[0014] 2. This reduction-type electronic flow scale drives the rotation of the worm by a stepper motor, so that the swing arm can swing in a fan shape with the cooperation of the worm gear, thereby breaking up and drying the grain materials inside the weighing hopper, avoiding them sticking to the inner wall of the weighing hopper during weighing, so that the materials can flow out smoothly during flow, preventing them from affecting subsequent weighing and reducing weighing errors.
