The purpose of this utility model is at above-mentioned deficiency, provide a kind of simple in structure, processing and fabricating is easy, cost is low, the work angle of inclination is big, promote the efficient Shaftless screw conveyor of decline angular length distance that convey materials is fast, fed distance is long.
The technical scheme that realizes the utility model purpose is:
The efficient Shaftless screw conveyor of this decline angular length distance, comprise stent support U moulding mixture groove, the cover plate on the U moulding mixture groove, be located at the inlet point on the cover plate, the discharging opening that is located at U moulding mixture trench bottom, motor, speed reduction gearing, characteristics are that the end at the U-shaped hopper is fixedly connected with bearing seat, the output shaft of speed reduction gearing is installed on the bearing seat by two-way flat thrust ball bearing and self-aligning ball bearing, captives joint with the Shaftless spiral blade in the U-shaped hopper by the output shaft of bearing seat; Be provided with U type liner plate in the inboard of U-shaped hopper.
Reveal in order to prevent material, further improve the transmission efficiency of Shaftless spiral blade to material, reduce the resistance of motion of Shaftless spiral blade, the profile of the zonate frond of described Shaftless spiral blade is spiral of Archimedes shape, also can be provided with and the equidirectional backgauge brush of blade at the outer shroud of Shaftless spiral blade and the edge of interior ring.
The utility model is simple in structure, can select raw MAT'L and general-duty parts such as existing carbon steel, corrosion-resistant steel for use, and adopts common process to be processed into, and implements easily.
Have advantages such as processing and fabricating is easy, cost is low, the work angle of inclination is big, the lifting convey materials is fast, fed distance is long, can be widely used in the conveying operation of various materials, have practical and popularizing value.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the cross-sectional view of Fig. 1 bottom bracket part.
Fig. 3 is the cross-sectional view of U moulding mixture slot part among Fig. 1.
Among the figure: 1 support, 2U moulding mixture groove, 3 cover plates, 4 inlet points, 5 discharging openings, 6 motors, 7 speed reduction gearings, 8 output shafts, 9 bearing seats, 10 two-way flat thrust ball bearings, 11 self-aligning ball bearings, 12 butt flanges, 13 Shaftless spiral blades, 14 backgauges brush, 15U type liner plate.
Specific embodiments
The utility model is further described with the embodiment that provides below in conjunction with accompanying drawing.
With reference to accompanying drawing, the efficient Shaftless screw conveyor of this decline angular length distance, is located at the inlet point 4 on the cover plate, the discharging opening 5 that is located at U moulding mixture trench bottom, motor 6, speed reduction gearing 7 and forms at the U moulding mixture groove 2 that is supported by support 1, the cover plate 3 on the U moulding mixture groove.Discharge port end at the U-shaped hopper is fixedly connected with bearing seat 9, the output shaft 8 of speed reduction gearing is installed on the bearing seat by two-way flat thrust ball bearing 10 and self-aligning ball bearing 11, output shaft by bearing seat is captiveed joint with Shaftless spiral blade 13 through butt flange 12, the profile of the zonate frond of Shaftless spiral blade is spiral of Archimedes shape, is respectively equipped with and the equidirectional thread backgauge brush 14 of blade at the outer shroud a of Shaftless spiral blade and the edge of interior ring b.Be provided with U type liner plate 15 in the inboard of U-shaped hopper.After the output shaft of speed reduction gearing passes bearing seat, drive Shaftless spiral blade by butt flange and in U moulding mixture groove, rotate, realize conveying material.
The utility model applicant presses the foregoing description, implements the efficient Shaftless screw conveyor of this decline angular length distance.Because driving the output shaft of Shaftless spiral blade is installed in the bearing seat, two-way flat thrust ball bearing and self-aligning ball bearing are installed in bearing seat simultaneously, can bear thrust axial and radially to greatest extent, bigger driving force is not acted directly on the speed reduction gearing, thereby material is realized the efficient conveying of high spud angle, long distance.Shaftless spiral blade adopts carbon steel or stainless steel usually, is generally 16Mn, and the profile of zonate frond is spiral of Archimedes shape.Because the edge at the Shaftless spiral blade outer shroud is provided with the thread backgauge brush made from the equidirectional high molecular abrasion-proof material of blade, make not direct friction U type liner plate of Shaftless spiral blade body, thereby reduced the resistance of motion of Shaftless spiral blade, can make the assemblage gap between Shaftless spiral blade and the U type liner plate reach 8 millimeters, the edge that encircles in Shaftless spiral blade simultaneously also is provided with thread backgauge brush, further actv. prevents the leakage of material, make Shaftless spiral blade when the inclination convey materials, also not influence transmission efficiency, thereby significantly improve the transmission efficiency of this Shaftless screw conveyor, under the situation of same output torque, can realize high spud angle, long distance, convey materials expeditiously.
The on probation demonstration through inside, the efficient Shaftless screw conveyor of this decline angular length distance, compact conformation is reasonable, work angle of inclination in the time of can making convey materials reaches more than 60 degree, the fed distance of the moving helical feed of patrilineal line of descent with only one son in each generation surpasses 30 meters, and the result of use ideal is subjected to probationer's favorable comment, after the popularization, application promise in clinical practice will be arranged.
