Abstract
The utility model discloses a screw type spring conveying device which comprises a sleeve. A spring is arranged in the sleeve and fixed to an output shaft of a driving motor arranged at the end of the sleeve. A feeding port is formed in the lower portion of the sleeve, and a discharging port is formed in the upper portion of the sleeve. A blade for discharging is arranged on the discharging port and fixed to the output shaft of the driving motor, and the rotating diameter of the blade is smaller than the inner diameter of the spring. The screw type spring conveying device has the advantages that because the spring is adopted, the part is long in service life and low in manufacturing cost. In addition, due to the fact that the discharging blade is arranged on the discharging port, accumulation of materials on the discharging port is avoided.
Description
Technical field
The utility model relates to mechanical field, is a kind of feedway specifically.
Background technology
In PE tubing or pvc pipe material production process, the feedway equipment that is absolutely necessary, as shown in Figure 1, vacuum pump 1 is connected with material storing box 3 with wind storehouse 6 by pipeline existing feeding device, and material is under the driving of negative pressure, from inlet point 4, enter feed bin 2, due to the effect of filter screen 5, material can not enter wind storehouse 6, and bin is filled after material, close vacuum pump 1, open the discharging opening of feed bin 2 belows.This apparatus structure is complicated, and, when toward feed bin convey materials, need to close the discharging opening of feed bin, otherwise cannot charging, therefore, operate discontinuous; In addition, complex structure, cost is high.Chinese Patent Application No. 201110364031.1 discloses a kind of Shaftless screw conveyor, it is characterized in that, at the two ends of feeding storehouse upside and downside, be respectively equipped with inlet point and discharging opening, discharge port end at feeding storehouse is connected with reductor by reducer pedestal, the output shaft of reductor is inserted in feeding storehouse, and establish a terminal pad, on terminal pad, weld a concentric shafts, near in the concentric shafts of terminal pad, be welded with shift fork, Shaftless spiral blade is located at the inside of feeding storehouse, and with concentric shafts weld together.By above setting, the present invention when the inlet point of feeding storehouse arrives outlet, can make material ratio more smoothly deliver from godown by stirring of shift fork at material, prevents that material is in the accumulation extruding of terminal pad place.This structure has adopted without helicallobe, and this blade construction is complicated, and as easy as rolling off a log distortion, affects the conveyer life-span.In addition, this structure adopts shift fork to prevent discharging opening accumulation, but this shift fork still can not prevent that material from continuing to pile up to the direction of discharging opening top.
Utility model content
For solving the problems of the technologies described above, it is simple that the purpose of this utility model is to provide a kind of blade construction, and guarantee the feedway that material can not piled up at discharging opening, and concrete technical scheme is as follows:
A spiral spring feeding device, comprises sleeve pipe, in described sleeve pipe, spring is set, and described spring is fixed with the output shaft that is arranged on the drive motor of cannula tip; The below of described sleeve pipe arranges inlet point, and the top of described sleeve pipe arranges discharging opening.
Described discharging opening place is provided for the blade of discharging, and described blade and drive motor output shaft are fixed; The rotating diameter of described blade is less than the internal diameter of spring.
The utility model has the advantages that: owing to having adopted spring, this parts long service life, and cost is low; In addition,, owing to being provided with discharging blade at discharging opening, avoided the accumulation of discharging opening material.
Accompanying drawing explanation
Fig. 1 is prior art schematic diagram;
Fig. 2 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, illustrate the utility model, as shown in Figure 2, the utility model comprises sleeve pipe 7, the interior spring 8 that arranges of described sleeve pipe 7, and described spring 8 is fixed with the output shaft 10 that is arranged on the drive motor 11 of sleeve pipe 7 ends; The below of described sleeve pipe 7 arranges inlet point 4, and described inlet point is arranged in material storing box 3, and the top of described sleeve pipe 7 arranges discharging opening 13; Described drive motor is fixed in frame 12.
Described discharging opening 13 places are provided for the blade 9 of discharging, and described blade 9 is fixing with drive motor output shaft 10; The rotating diameter of described blade 9 is less than the internal diameter of spring 8 to avoid blade 9 and spring 8 to interfere.
Claims (2)
