Grain distributer
Technical field:
The utility model relates to a kind of put in storage grain distributer of operation of silo grain that is used for.
Background technology:
At present domestic the put in storage dynamical type grain distributer of operation of silo that is used for, its type of belt drive mainly is to drive an axle rotation by a motor through chain-driving or strap drive, axle drives two or more chute rotations again, grain flows out in the chute of non-rotary elephant trunk and rotation, reaches cloth grain in the storehouse.Because adopting the mode of axle rotation to drive chute rotates, wherein S. A. all is mounted in non-rotary elephant trunk center, S. A. is installed on the elephant trunk wall by several reinforced ribs, the part of the drive mechanism between S. A. and the motor also is positioned at elephant trunk inside, these reinforced ribs and drive mechanism reduce the grain flow area in the elephant trunk, putty very easily has influence on the normal operation of grain distributer.Existing in addition this type of drive is horizontal transmission, moves very unstablely, is easy to occur that messenger chain is taken off or the drive belt slip phenomenon.
The utility model content:
The utility model is to overcome deficiency and the defective that prior art exists, and provides a kind of simple in structure, reliable operation, and cloth grain is even, put in storage the continuously grain distributer of operation of the Bulk Grain that is applicable to various silos.

Described outside race is a bull gear, on the output shaft of described driver train gear is installed, this gear and the engagement of bull gear coupling.
Described driver train is a motor-driven, and perhaps described driver train is motor and retarder.
A kind of grain distributer, be fixed on the grain-entering mouth place, upper end, top, storehouse of silo, driver train and transmission device are installed on support, lower surface at this support upper plate is fixed with a support tube, this support tube outside is equipped with an annular by the bearing cooperation and turns, and the output shaft of described driver train is turned by transmission device and this annular and is in transmission connection; The lower end of turning in described annular is fixed with elephant trunk, is fixed with the collection grain bucket of band chute in the elephant trunk lower end.
Described annular is turned and is on the output shaft of described driver train gear to be installed by gear ring, this gear and the engagement of gear ring coupling.
Described annular is turned and is on the output shaft of described driver train driving pulley to be installed by belt pulley, and this driving pulley is connected by belt-driving with the belt pulley of turning.
Described annular is turned and is annular sprocket wheel, on the output shaft of described driver train drive sprocket is installed, and this drive sprocket is connected by chain gear with annular sprocket wheel.
At support tube and the radial bearing of the bearing of annular between turning for matching, the perhaps surface bearing for matching, perhaps thrust baring for matching with its structure with its structure with its structure.
Described driver train is a motor-driven, and perhaps described driver train is motor and retarder.
The beneficial effects of the utility model:
1, overcome the deficiency of dynamical type grain distributer in the past, grain distributer of the present utility model adopts the mode of grain under the elephant trunk, and driver train is positioned at its outside, and self is driven in rotation elephant trunk, and the transmission S. A. is not installed at the elephant trunk center, is difficult for taking place putty.When putting in storage, grain is evenly distributed in the storehouse through elephant trunk, collection grain bucket and chute.
2, grain distributer of the present utility model is simple in structure, reliable operation, and cloth grain is even, the Bulk Grain that the is applicable to various silos operation of putting in storage continuously.
3, grain distributer of the present utility model can adopt miniature gears to drive the rotating disk rotation, thereby drives elephant trunk, collection grain bucket, the chute rotation that links to each other with rotating disk, and drive mechanism is simple, reliable operation, be difficult for et out of order, this frame mode is dismantled conveniently simultaneously, for ease of maintenaince.
