Description

Technical Field

[0001] The utility model belongs to the field of conveying equipment and relates to an electric gate of a disk feeder. Background Art

[0002] To control the size of the material flow, a gate is usually arranged at the discharge port of the disk feeder to adjust the height of the material flow. Such a gate mostly adopts a manual mode, and it is necessary to manually operate the handwheel to rotate the lead screw, and then drive the gate to move up and down to adjust the opening height of the discharge port so as to control the material flow.

[0003] However, since the length of the lead screw and its adjusting device often exceeds the internal space of the disk sleeve, it can only be arranged on the surface of the external equipment of the disk feeder. This traditional gate structure not only occupies external space and affects the layout and installation of the gate, but also the position of its adjusting device is relatively high, making it difficult for on-site personnel to reach even when standing on the disk maintenance platform, which brings inconvenience to operation and maintenance.

[0004] Furthermore, to improve the utilization rate of raw materials, metallurgical enterprises have significantly increased the types of raw materials in the raw material feeding and batching process. The bulk specific gravity and moisture content of these raw materials are different, and the batching ratios also vary greatly. Therefore, higher requirements are put forward for the adjustment of the feeding amount of the disk feeder. Each time the material ratio is changed, the feeding amount needs to be adjusted. This results in frequent manual adjustments by on-site enterprise personnel, increasing the personnel requirements and work intensity of the enterprise. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide an electric gate of a disk feeder, optimize the layout position of the gate, and improve the adjustment convenience of the gate.

[0006] To achieve the above purpose, the utility model provides an electric gate of a disk feeder. The disk sleeve of the disk feeder includes an upper disk and a lower disk, and the material enters from the upper disk, and the discharge port is arranged below the lower disk. The electric gate is arranged on the lower disk at a position corresponding to the discharge port, and it vertically rises and falls between the lower disk and the discharge port. The motor for driving the electric gate to rise and fall is installed on the lower disk with the output shaft parallel to the electric gate.

[0007] Optionally, the electric gate realizes vertical lifting through a lead screw slider mechanism. The lead screw slider mechanism includes a lead screw and a slider slidably arranged on the lead screw along the extension direction of the lead screw. The lead screw is vertically arranged on the lower disk, and the slider is fixedly connected to the upper part of the electric gate.

[0008] Optionally, a rectangular opening is provided at the position corresponding to the discharge port on the lower disk, and the electric gate vertically rises and falls in the rectangular opening.

[0009] Optionally, the lead screw and the motor are connected by a speed reducer to convert the rotational motion of the output shaft of the motor into the rotational motion of the lead screw.

[0010] Optionally, the input shaft of the speed reducer and the output shaft of the motor are connected by a coupling.

[0011] Optionally, the guide rail is vertically arranged on the inner wall surface of the discharge port, extends upward and passes through the lower disc through a rectangular opening, and the electric gate slides in the guide rail.

[0012] Optionally, a limit block for preventing the slider from disengaging is provided at the upper end of the lead screw.

[0013] Optionally, the electric gate is a flat gate.

[0014] Optionally, a wear-resistant lining is laid on the material-facing surface at the lower part of the electric gate.

[0015] The beneficial effects of the present utility model are as follows:

[0016] The present utility model provides an electric gate for a disk feeder. The electric gate and its driving mechanism are arranged within the limited space of the lower disk, and the overall structure is compact without occupying the external space of the disk feeder. By means of electric adjustment, the traditional manual adjustment mode and the limitation of relying on the external space to arrange the gate adjustment device are eliminated. This not only greatly improves the convenience of gate adjustment and gate arrangement, but also can efficiently and reliably control the height of the material flow. In addition, the electric gate has the self-locking property of the opening height and the impact resistance to the material flow, ensuring its stability and durability during use. Most importantly, this innovative design provides a solid foundation for subsequent realization of automatic and intelligent adjustment of the material flow size, and has significant application advantages and popularization value.

[0027] To effectively adjust the material flow height at the discharge opening 11 of the disk feeder, the present utility model provides an electric gate 4 for the disk feeder. The disk sleeve 1 of the disk feeder includes an upper disk 2 and a lower disk 3. Materials enter from the upper disk 2, and the discharge opening 11 is arranged below the lower disk 3. The electric gate 4 is arranged on the lower disk 3 and corresponds to the position of the discharge opening 11, and it realizes vertical lifting between the lower disk 3 and the discharge opening 11 through a lead screw slider mechanism vertically arranged on the lower disk 3.

[0028] Specifically, the motor 7 for driving the lifting of the electric gate 4 is installed on the lower disk 3, and its output shaft is parallel to the electric gate 4. The lead screw 5 of the lead screw slider mechanism is vertically arranged on the lower disk 3, and the slider 6 is slidably arranged on the lead screw 5 and fixedly connected to the upper part of the electric gate 4. In this way, when the lead screw 5 rotates, the slider 6 will slide up and down along the lead screw 5, thereby driving the electric gate 4 to realize lifting. The reducer 9 is arranged between the motor 7 and the lead screw slider mechanism, playing the role of decelerating and increasing torque. The output shaft of the motor 7 is connected to the input shaft of the reducer 9 through a coupling 8, and the output shaft of the reducer 9 is connected to the lead screw 5, making the rotation axis of the lead screw 5 perpendicular to the rotation axis of the motor 7, and converting the rotational motion of the output shaft of the motor 7 into the rotational motion of the lead screw 5.

[0029] Furthermore, a rectangular opening is provided at the position corresponding to the lower disk 3 and the discharge opening 11, and the electric gate 4 realizes vertical lifting within this rectangular opening. To ensure the stability of the electric gate 4 during the lifting process, the guide rail 10 is vertically arranged on the inner wall surface of the discharge opening 11 and extends upward through the rectangular opening and out of the lower disk 3. The guide rail 10 has a groove, and the electric gate 4 slides in the groove of the guide rail 10. A limit block is arranged at the upper end of the lead screw 5, and the limit block at the upper end of the lead screw 5 and the end face of the reducer 9 at the lower end of the lead screw 5 form a limit mechanism to prevent the slider 6 from disengaging from the lead screw 5.

[0030] In addition, the electric gate 4 adopts a flat plate type design, and a wear-resistant lining is laid on the material-facing surface of its lower part to improve the impact resistance of the material flow. When the electric gate 4 moves upward with the slider 6 to the top end of the lead screw 5, at this time the electric gate 4 is fully opened, and the material flow height at the discharge opening 11 is the largest; when the electric gate 4 moves downward with the slider 6 to the bottom end of the lead screw 5, at this time the electric gate 4 is fully closed, and the material flow height at the discharge opening 11 is the lowest. By adjusting the rotational speed of the motor 7, the transmission ratio of the reducer, and the rotational ratio of the lead screw, the up and down movement speed of the flat gate and the time required for opening and closing can be calculated. Cooperating with the computer program, remote adjustment of the material flow height can be realized.

[0031] With such a design, the utility model not only realizes the overall structure of the electric gate 4 arranged in the limited space inside the disc sleeve 1, but also realizes the function of electrically adjusting the material flow height of the discharge port 11, providing a basis for subsequent realization of automatic and intelligent adjustment of the material flow size.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and not to limit them. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions, and they should all be covered by the scope of the claims of the utility model.
