Description

Revolution driving mechanism of rail type grain delivery machine

Technical Field

The utility model relates to a bulk cargo storage technical field specifically is a rail mounted grain delivery machine revolution actuating mechanism.

Background

The vertical silo is a main form of bulk storage and is widely applied to the storage fields of grains, feeds, bulk meal, wood chips and chemical raw materials. The silo is generally provided with a discharge port at the bottom of the silo for discharging materials, but the materials with poor self-flowing property are difficult to discharge from the silo by means of self-flowing of the materials, and forced discharging equipment needs to be arranged at the discharge port.

The central turntable of the silo auger discharging machine is arranged at the central discharge port at the bottom of the silo, one end of the spiral conveying auger is arranged at the central turntable, and the other end of the spiral conveying auger is close to the silo wall. When discharging, the discharging machine is buried by the materials, the spiral auger rotates to convey the materials to the central discharging port, the central turntable and the spiral conveying auger revolve around the center of the silo, and the auger shaft covers the bottom of the whole silo once every revolution. The rail type grain delivery machine is characterized in that a circle of rail is laid at the tail end of the auger close to the wall of the bin, one end of a back plate is arranged to be connected with a central disc, the other end of the back plate is supported on the rail, and a bearing seat at the tail end of the auger is connected to the tail end of the back plate so as to revolve along with the back plate in a way of walking and propelling on the rail.

When the orbital grain delivery machine revolves, a buckle chain wheel is meshed with a cylindrical tooth surface on the track and rotates to walk along the track, the revolution driving motor and the speed reducer of the conventional orbital grain delivery machine are positioned at the tail end of the grain delivery auger and close to the track, materials in the bin are completely buried under the materials, the revolution driving system cannot be maintained and overhauled, the revolution motor and the speed reducer are large in size, the resistance of the materials is large during revolution propelling, and a power pipeline of the orbital grain delivery machine also needs to penetrate through the inner cavity of the auger back plate from the central turntable and be connected to the track end.

On the other hand, due to factors such as installation error and deformation of the radius of the track, the distance between the periphery of the track and the output end of the driving speed reducer floats to a certain extent, so that the meshing point of the chain wheel and the track deviates from the theoretical position, and the chain wheel is derailed or extruded to damage the revolution driving device. Therefore, the connection between the output of the revolution drive reducer and the sprocket needs a floating connection to compensate for the deviation. Although the standard telescopic universal joint coupler and the like can meet the compensation requirements of angles and displacement, the radial size is larger, the rated torque is lower, the telescopic universal joint coupler is buried in materials, the running reliability is insufficient, and personnel cannot enter the maintenance process if the telescopic universal joint coupler is suddenly failed. Therefore, the orbital silo discharging machine revolution driving mechanism is provided.
