Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-7, the present invention provides an embodiment:

the utility model provides a split type coal scuttle of impeller feeder, includes main receiving hopper 3, vice receiving hopper 5, connecting plate 4, first connecting bolt 6, second connecting bolt 7 and third connecting bolt 8, and main receiving hopper 3 is connected through first connecting bolt 6 with 4 one ends of connecting plate, and vice receiving hopper 5 passes through second connecting bolt 7 with the 4 other ends of connecting plate to be connected, and main receiving hopper 3 and vice receiving hopper 5 are connected through flange 9 cooperation third connecting bolt 8 simultaneously.

Main hopper 3 is located the impeller feeder left side, and the installation is accomplished the back and is fixed in impeller feeder speed reducer base 1 through the bolt, and main hopper 3 is installed in impeller feeder left side, need not hoist main hopper 3 when maintaining or changing impeller feeder speed reducer 2, reduces staff's maintenance pressure and loaded down with trivial details degree.

The auxiliary receiving hopper 5 is formed by two small receiving hoppers and is located on the right side of the impeller coal feeder speed reducer 2, and is located above an input shaft of the impeller coal feeder speed reducer 2, when the impeller coal feeder speed reducer 2 is overhauled and hoisted, only connecting part bolts of all the components need to be removed, and then the auxiliary receiving hopper 5 and the connecting plate 4 are hoisted, so that the hoisting risk caused by deformation, damage and space limitation of the coal hopper during hoisting is solved.

Connecting plate 4 is located between main receiving hopper 3 and the vice receiving hopper 5, lies in directly over the impeller feeder speed reducer 2 main parts simultaneously, through being provided with connecting plate 4, connecting plate 4 plays the effect of connecting main receiving hopper 3 and vice receiving hopper 5, increases main receiving hopper 3 and vice receiving hopper 5's connection fixity at main receiving hopper 3 and vice receiving hopper 5 during operation, makes its fixed firm more avoid taking place the shakiness, produces the potential safety hazard.

Flange 9 is located main hopper 3 and the 5 circular arc junctions of vice hopper and main vice hopper 5 bottoms, connect main hopper 3 and vice hopper 5 through utilizing flange 9 and third connecting bolt 8 and replace the welding of traditional connection, because impeller feeder and the coal scuttle locate ambient air humidity big, long-term corrosion, there is the deformation of welding department certain degree the coal scuttle after hoist and mount, there is the condition emergence that the repacking did not target in place when the repacking, be convenient for repack the coal scuttle through flange 9 and third connecting bolt 8.

The working principle is as follows: when the split coal bucket of the impeller coal feeder is used, because the speed reducer 2 of the impeller coal feeder is positioned below the coal bucket, when the speed reducer 2 of the impeller coal feeder is maintained or replaced, the coal bucket needs to be hoisted, then maintained and replaced, through the arrangement of the main receiving hopper 3, the auxiliary receiving hopper 5 and the connecting plate 4, when the speed reducer 2 of the impeller coal feeder is maintained and hoisted, only connecting bolts of all components need to be dismantled, and then the auxiliary receiving hopper 5 and the connecting plate 4 are hoisted, so that the hoisting risks caused by deformation, damage and space limitation during hoisting of the coal bucket are solved, the traditional connection welding is replaced by connecting the main receiving hopper 3 and the auxiliary receiving hopper 5 through the flange 9 and the third connecting bolt 8, and because the environment air humidity of the impeller coal feeder and the coal bucket is high, the coal bucket is rusted for a long time, and the coal bucket has deformation of a certain degree at the welding position after hoisting, when the coal bucket is reassembled, the coal bucket can be reassembled conveniently through the flange 9 and the third connecting bolt 8.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
