[0021] This embodiment provides an automatic control device for a flap valve on a feed pipe. Please refer to [link / reference]. Figure 1 The details are as follows:

[0022] The device includes: a valve body 1, with connecting flanges at both the top and bottom, and mounting holes on the valve body 1; a left bearing seat 3, fixedly mounted on the left side of the valve body 1; a right bearing seat 13, fixedly mounted on the right side of the valve body 1; a rotating shaft 12, mounted on the mounting holes on the valve body 1, with the left end of the rotating shaft 12 mounted on the left bearing seat 3 via a bearing, and the right end of the rotating shaft 12 mounted on the right bearing seat 13 via a bearing; a valve plate 15, fixedly mounted in the middle of the rotating shaft 12 and located inside the valve body 1; and a left drive unit, fixedly mounted on the left end of the rotating shaft 12, comprising: a left handle 2, fixedly mounted on the left end of the rotating shaft 12; a left support 4, fixedly mounted on the lower end of the left handle 2; and a left hinge seat 7, fixedly mounted on the left side of the rotating shaft 12. The system comprises: a left electric cylinder 6, the lower end of which is hinged to a left hinge seat 7, and the upper end of which is hinged to a left support 4 via a left fish-ear connector 5; a right drive unit, which is fixedly installed on the right end of a rotating shaft 12, comprising: a right handle 11, which is fixedly installed on the right end of a rotating shaft 12; a right support 17, which is fixedly installed on the lower end of the right handle 11; a right hinge seat 8, which is fixedly installed on the valve body 1; a right electric cylinder 9, the lower end of which is hinged to a right hinge seat 8, and the upper end of which is hinged to a right support 17 via a right fish-ear connector 10; and a maintenance door panel 16, which is fixedly installed on a flange on the front side of the valve body 1 by screws, and has a handle 14 installed on it.

[0023] Furthermore, a rotary seal is installed between the left side of the rotating shaft 12 and the left side mounting hole of the valve body 1, and a rotary seal is installed between the right side of the rotating shaft 12 and the right side mounting hole of the valve body 1. This effectively seals the valve body, preventing powder from escaping from the valve body and causing environmental impact.

[0024] Furthermore, two magnetic induction switches are installed on both the left electric cylinder 6 and the right electric cylinder 9. This allows for effective detection of both the working position and the material discharge position of the valve plate 15, eliminating the need for on-site maintenance and significantly improving work efficiency.

[0025] Furthermore, telescopic dust covers are installed on the outer sides of both the left electric cylinder 6 and the right electric cylinder 9. This effectively achieves a dustproof and sealing effect, and effectively protects the left electric cylinder 6 and the right electric cylinder 9.

[0026] Furthermore, both the left electric cylinder 6 and the right electric cylinder 9 on the automatic control device of the flap valve for the feed pipe are equipped with drive motors, and dual-motor drive control is adopted. Alternatively, only the drive motor can be installed on the left electric cylinder 6, and the left electric cylinder 6 is connected to the right electric cylinder 9 through a connecting shaft, thereby driving the movement of the right electric cylinder 9.

[0027] The above-described one or more technical solutions in the embodiments of this utility model have at least one or more of the following technical effects:
