Disclosure of Invention
The utility model provides a lower anti-drop chain wheel of a bucket elevator of a loop chain, which avoids a large block of materials from being brought between a lower chain wheel and a chain as far as possible through the improved design of a chain wheel structure, and even if the large block of materials are brought between the chain and a roller, the chain can not drop off even if the chain only slightly swings.
The utility model adopts the technical scheme that:
the utility model provides a chain bucket elevator lower part anticreep sprocket, includes cylindric main part, the both ends of cylindric main part are sealed, and its both ends face central authorities are provided with wheel hub respectively, wear to be equipped with the pivot between two wheel hubs, the both ends face border of cylindric main part outwards extends and is formed with round flange, just the outside border diameter of flange is greater than the diameter of cylindric main part.
Preferably, the outer end of the flange is provided with a circular reinforcing plate, the outer end of the hub passes through the circular reinforcing plate, and the outer end of the hub is fixed on the circular reinforcing plate.
Preferably, reinforcing ribs are arranged between the round reinforcing plate and the end face of the cylindrical main body at intervals, one end of each reinforcing rib is arranged on the flange, and the other end of each reinforcing rib is arranged on the outer side of the hub.
Preferably, the round reinforcing plate is provided with weight-reducing through holes at intervals, and the weight-reducing through holes are arranged around the hub.
Preferably, the elastic check ring is arranged at the matching part of the rotating shaft and the hub, and the elastic check ring is arranged at the outer side of the hub and is tightly attached to the hub.
Compared with the prior art, the utility model has the beneficial effects that: this chain bucket elevator lower part anticreep sprocket adopts cylindric main part, and the chain is side by side and little interval around establishing in cylindric main part, can try to avoid the bulk material to bring into between lower part sprocket and the chain when drawing the material, sets up the round flange simultaneously respectively at cylindric main part both ends, even if there is the bulk material to bring into between chain and the cylinder, the chain only has slight swing and can not take off the chain, and simultaneously under the circumstances that the sprocket was constantly rotated, the material also can fall by oneself.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a left side view of the spindle of fig. 1 with the spindle removed.
In the accompanying drawings: 1. a cylindrical main body; 2. a hub; 3. a rotating shaft; 4. a flange; 5. a circular reinforcing plate; 6. a weight-reducing through hole; 7. reinforcing ribs; 8. and (5) a circlip.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the anti-drop chain wheel at the lower part of the loop chain bucket elevator comprises a cylindrical main body 1, wherein two ends of the cylindrical main body 1 are closed, hubs 2 are respectively arranged in the centers of two end surfaces of the cylindrical main body, a rotating shaft 3 is arranged between the two hubs 2 in a penetrating way, a circle of flange 4 is formed by outwards extending the edges of the two end surfaces of the cylindrical main body 1, and the diameter of the outer edge of the flange 4 is larger than that of the cylindrical main body 1. The lower chain wheel of the loop chain bucket elevator is changed into a drum-type structure with edges at two ends, and as shown in fig. 1, the loop chains are arranged side by side and are wound on the cylindrical main body at small intervals, so that the situation that large materials are brought between the lower chain wheel and the chain is avoided to a great extent, even if the large materials are brought between the chain and the drum, the chain only swings slightly and cannot be separated, and meanwhile, the materials can fall down automatically under the condition that the chain wheels rotate continuously.
As shown in fig. 2, in order to protect the flange from direct impact of material on the flange to deform it, the outer end of the flange 4 is provided with a circular reinforcing plate 5, the outer end of the hub 2 is disposed through the circular reinforcing plate 5, and the outer end of the hub 2 is fixed on the circular reinforcing plate 5.
In addition, in order to ensure the stability of the circular reinforcing plate, reinforcing ribs 7 are arranged at intervals between the circular reinforcing plate 5 and the end face of the cylindrical main body, the reinforcing ribs are welded on the end face of the cylindrical main body and are arranged to be attached to the circular reinforcing plate, one end of each reinforcing rib 7 is arranged on the flange 4, and the other end of each reinforcing rib is arranged outside the hub 2.
In order to reduce the weight of the round reinforcing plate, the round reinforcing plate 5 is provided with weight reducing through holes 6 at intervals, and the weight reducing through holes 6 are arranged around the hub. Under the condition of reinforcing ribs, the weight-reducing through holes are arranged between every two reinforcing ribs at intervals.
In this embodiment, the lower anti-disengaging sprocket is fixed on the rotating shaft through the hubs on both sides, and the circumferential positioning of the hubs and the rotating shaft can be various, so long as it is reasonable, and no specific limitation is made. However, in order to protect the rotating shaft and prevent dust from entering the inner side of the rotating shaft, a circlip 8 is arranged at the matching position of the rotating shaft 3 and the hub 2, and the circlip 8 is arranged on the outer side of the hub 2 and is tightly attached to the hub 2.
