In order to realize above-mentioned object, the utility model have employed following technical scheme:
A kind of screw extruder of automatic draining, this screw extruder comprises charging aperture and screw device, screw device below charging aperture is provided with delivery port, be provided with automatic draining agitating device below delivery port, described automatic draining agitating device comprises motor, drive sprocket, driven sprocket, bearing block, bearing, holder and crank slot roller; Described holder is " U " type structure, the upper/lower terminal of holder is respectively arranged with installing hole, linear bearing is respectively arranged with in installing hole, described crank slot roller is arranged in holder, the outer ring circumferencial direction of crank slot roller is provided with crank slot, the madial wall of described holder is provided with the fixed axis of protrusion, and fixing the tip of the axis is contained in crank slot; And the upper end of crank slot roller is provided with axle head, lower end is provided with lower shaft end, and upper axle head and lower shaft end are separately positioned in linear bearing, and the upper end of upper axle head is provided with eccentric stirring-head, and the upper end of eccentric stirring-head is contained in delivery port; The lower shaft end of crank slot roller is provided with spline, and described driven sprocket is provided with spline, and lower shaft end and driven sprocket are interconnected by spline and spline; Described bearing block is arranged on below holder, the upper end of driven sprocket is arranged in bearing block by location jump ring, bearing is arranged between the upper end of driven sprocket and bearing block, and the lower end of driven sprocket is by chain and drive sprocket, and drive sprocket is connected with motor.
As preferably, described fixing the tip of the axis is provided with little bearing, and described little bearing is contained in crank slot.
As preferably, described bearing block is bolted and is arranged on below holder, and described bearing is two, between two bearings, be provided with positioning sleeve.
As preferably, described motor is fixedly installed on holder outer right wall.
The utility model is owing to have employed above-mentioned technical scheme, the eccentric stirring-head of this device can move up and down, again because be eccentric, in the process that roller rotates, this stirring-head will do a circular trace, so the track of this stirring-head is circular curve motion, this eccentric orbit diameter is basic and extruder delivery port is in the same size, so just effectively the lighter raw material of the inside can be emptied, water can be discharged smoothly.The utility model have structure simple, implement feature easily.

Fig. 2 is the structural representation of the utility model automatic draining agitating device.
Fig. 3 is the structural representation of bearing block.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is made a detailed explanation.
The screw extruder of a kind of automatic draining as shown in Figure 2, this screw extruder comprises charging aperture 17 and screw device 18, screw device 18 below charging aperture 17 is provided with delivery port 19, be provided with automatic draining agitating device below delivery port 19, described automatic draining agitating device comprises motor 1, drive sprocket 2, driven sprocket 4, bearing block 5, bearing 13, holder 6 and crank slot roller 8; Described holder 6 is " U " type structure, the upper/lower terminal of holder 6 is respectively arranged with installing hole, linear bearing 7 is respectively arranged with in installing hole, described crank slot roller 8 is arranged in holder 6, the outer ring circumferencial direction of crank slot roller 8 is provided with crank slot 12, the madial wall of described holder 6 is provided with the fixed axis 11 of protrusion, and the end of described fixed axis 11 is provided with little bearing 10, and described little bearing 10 is contained in crank slot 12.And the upper end of crank slot roller 8 is provided with axle head, lower end is provided with lower shaft end, and upper axle head and lower shaft end are separately positioned in linear bearing 7, and the upper end of upper axle head is provided with eccentric stirring-head 9, and the upper end of eccentric stirring-head 9 is contained in delivery port 19.The lower shaft end of crank slot roller 8 is provided with spline, and described driven sprocket 4 is provided with spline, and lower shaft end and driven sprocket 4 are interconnected by spline and spline.As shown in Figure 3, described bearing block 5 is fixedly installed on below holder 6 by bolt 16, the upper end of driven sprocket 4 is arranged in bearing block 5 by location jump ring 15, bearing 13 is arranged between the upper end of driven sprocket 4 and bearing block 5, described bearing 13 is two, is provided with positioning sleeve 14 between two bearings 13.The lower end of driven sprocket 4 is by chain and drive sprocket 2, and drive sprocket 2 is connected with motor 1, and described motor 1 is fixedly installed on holder 6 outer right wall.
As shown in Figure 1, raw material drops into from the charging aperture 17 on screw extruder 18 top, and a delivery port 19 is arranged at screw extruder 18 bottom, and delivery port 19 is exactly the automatic draining agitating device of our design below.This device drive sprocket 2 is driven by motor 1, after driven sprocket 4 rotates, because driven sprocket 4 is decided to be at above-below direction, so can not slide up and down, only have a rotary action, such crank slot roller 8 also rotates under the effect of sprocket wheel, but because have a little bearing 10 in crank slot 12, this little bearing 10 is fixed with holder 6, so when crank slot roller 8 rotates, under the effect of little bearing 10, also can move up and down, therefore, this crank slot roller 8 axle is upper and lower rotary motion.On crank slot roller 8, axle head has an eccentric stirring-head 9, in the process of crank slot roller about 8, this eccentric stirring-head 9 will move up and down, again because be eccentric, in the process that roller rotates, this stirring-head will do a circular trace, so the track of eccentric stirring-head 9 is circular curve motion, this eccentric orbit diameter is basic and extruder delivery port 19 is in the same size, so just effectively can be emptied by the lighter raw material of the inside, water can be discharged smoothly.
