Generally, above-mentioned drive unit is motor, and one end of the output shaft of motor and the feeding spiro rod body of rod is in transmission connection.Above-mentioned drive unit also can comprise transmission mechanism (as gear train, sprocket wheel and chain, belt pulley and belt etc.) and other power set, and one end of the feeding spiro rod body of rod is in transmission connection by transmission mechanism and power set.
Different materials leaves in hopper in advance, and material enters mixing of materials storehouse through charging aperture from hopper, and fills up the space (having partial material directly directly to send from discharging opening while certainly starting) in mixing of materials storehouse; Because forward thread segment is contrary with the hand of spiral of reverse thread section, drive unit drives feeding spiro rod to press certain orientation and rotates, and forward thread segment and reverse thread section all promote material makes material carry toward middle from feeding spiro rod two ends; The feeding speed of forward thread segment and reverse thread section is set to be greater than the discharging speed of discharging opening, when material converges in centre, due to from two ends to middle extruding force effect, partial material is sent by discharging opening, another part material upwards arches upward, and rises gradually, when the material that arched upward reach a certain height, just past two ends disperse, thereby complete the mixing of material one-period.From the above-mentioned course of work, can find out, this pressure pay-off with mixed function can be realized mixing and the conveying of material, is that material mixing device and device for transporting objects are closely linked, and structure is quite compact, takes up room little, economizes the land resource; On the other hand, owing to sending into process equipment by discharging opening immediately after mixing of materials, there is no middle conveying process, material can layering, thereby has improved the quality of goods after processing; In addition, due to when mass transport is obstructed, the amount of the material of down carrying can reduce, and the amount of the material that mixes of up arching upward can increase, and can effectively avoid strengthening and causing the problems such as drive unit overload because transmission failure produces transporting resistance.
As preferred version of the present invention, it is characterized in that: also comprise that outlet valve, outlet valve are arranged on described discharging opening.Before feeding, first close outlet valve, carry out the premixed of material, just open outlet valve and start feeding when mixing of materials is even, the material that makes to send for the first time just reaches the uniformity requirement of mixing, has further improved the qualification rate of goods.
As preferred version of the present invention, it is characterized in that: described mixing of materials storehouse is tubular.Mixing of materials storehouse is set to tubular, is more conducive to material and carries to centre from the two ends in mixing of materials storehouse, makes the material of carrying in the middle of two side direction have stronger extruding force, thereby obtains better mixing of materials effect.
The present invention compared with prior art, there is following beneficial effect: forward thread segment and reverse thread section all promote material toward middle feeding the mixing of having arched upward, on same device, realize mixing and the conveying of material, be that material mixing device and device for transporting objects are closely linked, structure is quite compact, take up room little, economize the land resource; On the other hand, owing to sending into process equipment by discharging opening immediately after mixing of materials, there is no middle conveying process, material can layering, thereby has improved the quality of goods after processing.
