Problems solved by technology
In the electric control mode, multiple hydraulic cylinders are required to open and close the bucket door, and the use cost and maintenance cost of the cylinders are high, resulting in a high overall cost of the electric control mode
Especially in some ports with heavy dust, hydraulic cylinders often break down due to dust pollution, which affects operations;
[0009] Secondly, it is inconvenient to operate

The invention provides a feed door opening and closing device which is used on a hopper and comprises a fixed frame, a hopper outlet, a fixed shaft, a wedge component, a first hopper door and a second hopper door. The first hopper door and the second hopper door are connected with the wedge component, one end of the fixed shaft is connected with the hopper outlet, the other end of the fixed shaft is connected with the fixed frame, and ratchet mechanisms are arranged on the wedge component and the fixed frame. According to the feed door opening and closing device with the structure, when the component sleeved on the fixed shaft rotates, the component can drive the first hopper door and the second hopper door fixedly connected with the component to rotate, and the first hopper door and the second hopper door can stay at optional positions, realize self-lock and are conveniently operated. Besides, the invention further provides the hopper comprising the feed door opening and closing device.
Description
technical field [0001] The invention relates to the field of machinery, in particular to a material door opening and closing device and a hopper. Background technique [0002] At present, there are mainly two types of opening and closing devices for the material door that are widely used. One is the electric control mode, that is, the opening and closing of the hopper door is driven by a servo motor or hydraulic device; the other is the manual control mode, that is, it is controlled by manual operation. Hopper door opening and closing. Among the manual control modes, one is purely manual opening and closing mode, which is completed by manual operation; the other is manual operation of bucket opening, and bucket closing is realized by hydraulic device or pneumatic device. [0003] In the electric control mode, the electric opening and closing bucket device is usually installed above the automatic conveyor belt. It is often used in continuous operation devices. In order to r...
