Abstract
The utility model discloses a spiral conveying feeder, which is composed of an electric motor (1), a driving chain wheel (2), a box body (8), a case body (9), a feeding spiral conveying shaft, transmission chain wheels and spiral conveying blades. The feeding spiral conveying shaft has two stages of cantilever type, one end near the feeding end is a hollow back spiral conveying shaft (10), and one end near the discharging end of the feeder is a solid preceding spiral conveying shaft (13). One end of the preceding spiral conveying shaft (13) is arranged on the inner ring of the back spiral conveying shaft (10). The preceding spiral conveying shaft (13) is fixed and connected with a multi-head screw pitch spiral conveying blade; the preceding spiral conveying shaft (13) is fixed and connected with the transmission chain wheel 1 (4), the back spiral conveying shaft (10) is fixed and connected with the transmission chain wheel 2 (6). Therefore the feeding speed of the preceding spiral conveying shaft (13) is faster than that of the back spiral conveying shaft (10), which avoids the material jam phenomenon effectively. Moreover, since the preceding spiral conveying shaft (13) adopts the structure of a plurality of screw pitch spiral conveying blades, the feeding of the feeder is uniform during discharging, effectively meeting the demand of feeding precision of the feeder.
Description
Affiliated technical field
The utility model relates to a kind of helical feed feeder that needs are accurately carried particle or granular material that is used for.
Technical background
At present general helical feed feeder is by screw-conveyer-shaft, several parts such as auger housing are formed, substantially can realize the conveying requirement of ordinary material, but in the design of having relatively high expectations for delivery precision, as the burden balance in the feed processing and the helical feed feeder of packing scale, all be to take to change the pitch of packing auger blade or adopt the form of two pitch airscrew even three pitch to improve the feeding degree of uniformity at the screw-conveyer-shaft discharging opening, reduce feeding capacity and improve the feeding precision, the screw-conveyer-shaft that has may be to adopting two kinds of rate of feeding of speed to satisfy the requirement of feeding precision, but all can't avoid existing the problem of material at feeder discharging opening putty.Because under or the situation that pitch is identical identical at rotating speed, the feeding capacity of bull pitch screw-conveyer-shaft is less than the feeding capacity of single-lead screw-conveyer-shaft.
Summary of the invention
The purpose of this utility model provides a kind of requirement that can not only satisfy feeding precision and feeding degree of uniformity, can solve the helical feed feeder of material in feeder discharging opening putty problem well simultaneously.
The purpose of this utility model is achieved in that the feeding screw-conveyer-shaft is designed to the cantilevered front and back stages, back level screw-conveyer-shaft near charging one end is designed to hollow shaft, prime screw-conveyer-shaft near the feeder discharge end is designed to solid axle, one end of prime screw-conveyer-shaft is installed on the inner ring of back level screw-conveyer-shaft, all affixed packing auger blade on the front and back stages screw-conveyer-shaft.
Further, the prime screw-conveyer-shaft has different driving chain wheels to drive respectively with back level screw-conveyer-shaft, forms the rotating speed of the rotating speed of prime screw-conveyer-shaft greater than back level screw-conveyer-shaft.
Further, the packing auger blade of prime screw-conveyer-shaft is made bull pitch.
Owing to adopt such scheme, material is transported to the prime screw-conveyer-shaft by back level dragon axle effect and transfers out feeder again during work, because feeder discharging opening front and back stages screw-conveyer-shaft is designed to the double speed feeding, simultaneously because the prime screw-conveyer-shaft is made is bull pitch, its feeding capacity can reach the feeding capacity that may extremely surpass back level screw-conveyer-shaft by changing its rotating speed, thereby can satisfy feeding precision and feeding degree of uniformity requirement, solve the problem of material at feeder discharging opening putty, can finish feeding requirement, compact conformation equably, accurately.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation
Among the figure: 1, reducing motor, 2, drive sprocket, 3, rolling bearing units I, 4, driving chain wheel I, 6, driving chain wheel II, 7, rolling bearing units II, 8, casing, 9, the auger housing, 10, back level screw-conveyer-shaft, 11, bearing, 12, seal ring, 13, the prime screw-conveyer-shaft.
The specific embodiment
In this example shown in the figure one, the utility model helical feed feeder has auger housing 9 and casing 8, prime screw-conveyer-shaft 13 is made solid axle, be fixed in hollow back level screw-conveyer-shaft 10 inner rings by bearing 11, front and back are fixed on the casing 8 with seal ring 12 sealings, prime screw-conveyer-shaft 13 and back level screw-conveyer-shaft 10 usefulness rolling bearing units I3 and rolling bearing units II7; On the screw-conveyer-shaft in casing 8, affixed driving chain wheel I4 on the prime screw-conveyer-shaft 13, affixed driving chain wheel II6 on the level screw-conveyer-shaft 10 of back; On the screw-conveyer-shaft in auger housing 9, affixed single-lead packing auger blade on the level screw-conveyer-shaft 10 of back, affixed three pitch structure packing auger blades on the prime screw-conveyer-shaft 13.Reducing motor 1 is fixed in the lateral surface of casing 8, drive sprocket 2 on reductor 1 main shaft is made duplex chain wheel, drive driving chain wheel I4 and driving chain wheel II6 respectively, by the master, the different numbers of teeth of driven sprocket realize the different rotating speeds of front and back stages auger, make the rate of feeding of the rate of feeding of prime screw-conveyer-shaft 13 greater than back level screw-conveyer-shaft 10, prevent the generation of putty phenomenon effectively, simultaneously because prime screw-conveyer-shaft 13 is three pitch forms, feeding is even when making the feeder discharging, guaranteed the requirement of feeder feeding precision effectively, reducing motor 1 can also be joined double-speed motor to improve the feeding precision.
