Abstract
The utility model relates to a pre-cleaning sieve for raw grain, comprising an inner and an outer sieve cylinders. A motor drives a circumferential chain of a rotary sleeve to rotate by a decelerating drive chain wheel, and the rotary sleeve drives the inner and the outer sieve cylinders which are connected with the rotary sleeve to rotate; the rotary sleeve is arranged in a box body, and an axial steel ball which is arranged inside the box body drives the rotary sleeve to rub in an axial positioning and rolling mode; a fixing shaft arranged inside the box body is provided with a radial carrier roll of the rotary sleeve to drive the rotary sleeve to do radial location and rolling support, and the other end of the inner sieve cylinder is also provided with a radial supporting carrier roll for auxiliary positioning. The utility model has the advantages of small size, light weight, convenient moving, stable running, long service life, etc.
Description
A kind of raw grain receiving sieve that relates to grain machinery is widely used in grain storage, processing enterprise.
Existing raw grain receiving sieve is divided into two kinds substantially, and a kind of for the through-drive sieve is arranged, another kind of is no through-drive sieve.The easy elongated bigger material that twines in the grain of axle of through-drive sieve is arranged, often need the labor cleaning, time-consuming; No through-drive sieve adopts belt pulley transmission, wheel rim and external support to adopt slip spacing, because frictional force is big, the wheel rim of belt pulley is easy to wear, and sieve rotates not steady, the fault rate height, and service life is low, and machine volume is big, and weight is big, is not easy to move.
The purpose of this utility model is to provide a kind of stability of rotation, and volume is little, and is in light weight, is convenient to move the raw grain receiving sieve of long service life.
The purpose of this utility model is realized by following technical scheme: a kind of raw grain receiving sieve, in it comprises, outer screen drum (8), (9), be nested with outer screen drum (9) on the interior screen drum (8), motor (7) is connected with decelerator (6), the output shaft of decelerator (6) is equipped with sprocket wheel (14), sprocket wheel (14) is connected with sprocket wheel (5), it is characterized in that: also comprise the sprocket wheel (13) that sprocket wheel (5) is coaxial, sprocket wheel (13) is meshed with the chain that is placed on turning set (11) (3), place turning set (11) both ends of the surface (20) in the casing (1) to contact with steel ball (2), steel ball (2) contacts with the two side of casing (1), the cylindrical of turning set (11) be loaded on casing (1) on the contacting of idler pulley (12), turning set (11) is connected with an end of interior screen drum (8), and the other end of interior screen drum (8) contacts with supporting idler pulley (10).
The advantage applies of raw grain receiving sieve of the present utility model exists:
1, because employing is nested with chain structure at the periphery of turning set, therefore simple in structure, be convenient to make;
2, owing to adopt arrangement end face steel ball and turning set axial location in casing, adopt idler pulley to make the turning set radial location, and axially, radially be the structure of rolling friction, make little, the stability of rotation of sieve rotary resistance, long service life;
3, since adopt put on the turning set driving-chain, rolling friction axially, the structure of radial location, machine volume is little, in light weight, is convenient to move.
The utility model is described in further detail to utilize embodiment shown in the drawings below.
Fig. 1 is a raw grain receiving sieve structural representation.
With reference to Fig. 1, the transmission device of raw grain receiving sieve comprises motor (7), motor (7) is connected with decelerator (6), be fixed with sprocket wheel (14) on the output shaft of decelerator (6), sprocket wheel (14) is connected by chain (15) with sprocket wheel (5), sprocket wheel (5) is loaded on the bearing block (4) with sprocket wheel (13) is coaxial, and sprocket wheel (13) is meshed with chain (3), and chain (3) places the circumference of turning set (11).In casing (1), settle turning set (11), turning set (11) both ends of the surface (20) are provided with the circumference ball impression, in the circumference ball impression, settle steel ball (2), the single face circumference ball impression of present embodiment is built-in with 12 steel balls, two-sidedly put 24 steel balls altogether, become two-sided thrust bearing, make turning set (11) axial location, rolling friction.On casing (1), be equipped with axle (21), idler pulley (12) is housed on axle (21), idler pulley (12) is a double row ball bearing, three supporting-points are set in the present embodiment, contact at the cylindrical of supporting-point position double row ball bearing with turning set (11), turning set (11) is a rolling bearing, radial location.Outer screen drum (9) is enclosed within on the interior screen drum (8), and an end of interior screen drum (8) and turning set (11) are fixing.The other end circumference of interior screen drum (8) contacts with supporting idler pulley (10), and supporting idler pulley (10) is a bearing, can be provided with two or three supporting-points on the circumference of interior screen drum (8), is rolling bearing, radial location at supporting-point position bearing and interior screen drum (8).
During use: motor (7) drives transmission device and rotates, grain is entered interior screen drum (8) from the inlet (16) of turning set (11), screen drum (9) outside grain and little foreign material fall into from the sieve aperture (22) of interior screen drum (8), bigger material on the interior screen drum (8) is discharged from outlet (17), little foreign material fall from the sieve aperture (19) of outer screen drum (9) again, and the grain in the outer screen drum (9) behind the sieve is discharged from outlet (18).
