Problems solved by technology
In the prior art, the planetary mixers used for mixing mortar are all of ordinary fan-shaped discharge door structure. Since this structure wears out the sealing material greatly, it is very easy to leak water and slurry at the seal. Once water leakage occurs, adjust also more difficult

The invention discloses a lifting rotary type discharging door device, comprising a discharging bin, a discharging door, a discharging door bracket, a lifting master cylinder, a rotating secondary cylinder, an air pressure device and a discharging door control switch, wherein the bottom of the discharging bin is provided with a discharging hole matched with the discharging door, the lower edge of the discharging hole is provided with an air pressure ring, the upper edge of the discharging hole is provided with a sealing base plate, a material stop block is arranged at one side of the bottom of the discharging bin where the discharging door is closed, the edge of the discharging door is provided with a sealing ring, the outer side of the sealing ring is adhered to the inner side of the sealing base plate, a positioning block is arranged at one side of the discharging door close to the material stop block, air pressure produced by the air pressure device is connected with the air hole by an air pressure delivery pipe, the discharging door control switch is arranged above the lifting master cylinder, and the air pressure device, the lifting master cylinder and the rotating secondary cylinder are all arranged on the side of the discharging bin.
Description
technical field [0001] The invention relates to a discharge door device, in particular to a lifting and rotating type discharge door device. Background technique [0002] Ordinary fan-shaped discharge doors are widely used on planetary mixers, vortex mixers and other models with round groove cylinders. The operation method is to use hydraulic cylinders as power to push one end of the discharge door, so that the discharge door rotates about 90 degrees to open When unloading, the oil cylinder retracts to the original position when it is closed, and the unloading door returns to the closed state. This structure is mainly sealed by the upper and lower sealing rubbers and the discharge door liner, but the disadvantage is that the discharge door liner will also generate motion friction between the upper and lower sealing rubbers during each operation. Therefore, this structure has extremely high requirements on the sealing material and wear resistance, and the frequency of replac...
