In a production process without a crushing procedure, the mixed lumps have many unfavorable factors in the conveying link due to the excessively large particle size range. The main performances are that the large-particle-size ores block the conveying and the small-particle-size ores are difficult to control the sliding phenomenon, which not only affects the smooth production, but also has safety risks such as object impact and collapse.

One end of the transmission rod 7 is hinged to the end of the opening and closing control lever 4 away from the movable door 3. By rotating the transmission rod 7, the opening and closing control lever 4 can be driven to rotate (the transmission rod 7, the opening and closing control lever 4 and the movable door 3 are combined to form a crank rocker structure). The bracket 5 is also provided with a position positioning part 8 for fixing the transmission rod 7. By fixing the position of the transmission rod 7, the movable door 3 can be fixed to prevent the movable door 3 from rotating under the action of external force during use.

[0035] The use mode of the present application is as follows:

[0036] When adjusting, the operator operates the handgrip 14 to rotate the transmission rod 7 through the handgrip 14, the rotation of the transmission rod 7 drives the opening and closing control rod 4 to rotate, the opening and closing control rod 4 drives the movable door 3 to rotate to the corresponding position required, at the same time, the transmission rod 7 rotates to drive the rotating shaft 6 and the positioning rod 801 to rotate simultaneously, the positioning rod 801 drives the positioning pin 803 to move in the clamping groove 806, when the transmission rod 7 rotates to the corresponding position, the positioning pin 803 is also located at the corresponding position in the clamping groove 806, at this time, the handle 13 is rotated to drive the clamping block 9 to rotate, because the eccentric hole 10 is arranged on the clamping block 9, the clamping block 9 drives the connecting rod 11 and the positioning pin 803 to move in the rotating process, so that the positioning rod 801 and the clamping block 9 press the positioning plate 805, the friction between the positioning rod 801 and the positioning plate 805 is increased, the positioning rod 801 is prevented from rotating under the action of external force, the rotating shaft 6 and the transmission rod 7 are fixed by fixing the positioning rod 801, when the position of the transmission rod 7 is fixed, the opening and closing control rod 4 and the movable door 3 cannot rotate, finally, the position of the movable door 3 is fixed and cannot rotate under the action of external force, the control of the flow is affected.

[0037] When the conveying strength of the mineral is small, the opening and closing degree of the movable door 3 can be reduced to prevent the mineral from flowing too fast, when the conveying strength of the mineral is large, the opening and closing degree of the movable door 3 can be increased to prevent poor conveying, in addition, because the opening and closing control rod 4 is arranged, the operator is far away from the movable door 3, and safety accidents can be effectively prevented.
