Example 1

Referring to fig. 1-5, the present invention provides the following technical solutions: a coal crushing device for a thermal power plant, which comprises a coal crusher body 1 and a driving wheel 2, motor 3, base 4 and stabilizer blade 5, the bottom mounting of coal pulverizer body 1 has base 4, the bottom mounting of base 4 has stabilizer blade 5, one side that the top of base 4 is close to coal pulverizer body 1 is fixed with motor 3, motor 3 and external power source electric connection, motor 3's output shaft fixedly connected with belt, the front surface mounting of coal pulverizer body 1 has drive wheel 2, drive wheel 2 is connected through belt drive with motor 3, the top welded fastening of coal pulverizer body 1 has feeder hopper 11, the top spiro union of feeder hopper 11 is fixed with guard portion 6, the inside wall welded fastening of feeder hopper 11 has second board 113, one side of second board 113 rotates through pivot 111 and is connected with first board 112, the inside wall welded fastening of stabilizer blade 5 has spout 51, the inside wall sliding connection of spout 51 has storage portion 52.

In this embodiment: when the motor 3 works, the motor 3 works in cooperation with the transmission wheel 2 to drive the hammer head to operate so as to realize the crushing function, wherein the model of the motor 3 is YE 2-315S-2.

In this embodiment: the 6 spiro union of guard portion is fixed at the lateral wall of feeder hopper 11, can block partial cinder through guard portion 6 and splash, injures workers on every side by a crashing object, and wherein guard portion 6 is stainless steel.

In this embodiment: storage portion 52 and spout 51 work of mutually supporting, storage portion 52 can collect the crushed aggregates of discharge gate output and store, goes out storage portion 52 through the pull, makes things convenient for the user of service to derive the crushed aggregates, and wherein storage portion 52 is for example the drawer.

In this embodiment: the first plate 112 is fixed by welding the second plate 113 fixed in the hopper 11, the first plate 112 can be turned over by the rotation shaft 111, and after the user introduces the coal into the hopper 11, because the coal falls on the first plate 112 under the action of gravity, the first plate 112 is turned downwards, the coal falls into the coal crusher body 1 downwards along the first plate 112, the first plate 112 rotates upwards and returns to the initial position, at the moment, the hammer head in the coal crusher body 1 works to crush the coal, the crushed slag splashes to the bottom end of the first plate 112, the first plate 112 can block partial crushed slag from splashing, the splashing distance of the crushed slag can be lengthened through the protection part 6, and the protection part 6 is rectangular table-shaped, so that a certain blocking effect can be achieved, and people can be prevented from being accidentally injured, as the sliding grooves 51 are welded on the inner side walls of the support legs 5, the storage part 52 is fixed through the sliding grooves 51 in a sliding mode, and people can conveniently collect pulverized coal.

Specifically, the shape of the protection part 6 is a rectangular table shape; because the shape of protection part 6 is rectangular platform form, protection part 6 is the lateral wall of inversion spiro union fixing at feeder hopper 11, enlarges the distance and the scope of splashing of coal crushed aggregates through protection part 6, plays certain effect of blockking, prevents that the coal crushed aggregates from directly splashing away by the discharge gate, injures the workman by a crashing object easily.

Specifically, the second plate 113 is attached to the inner sidewall of the feeding hopper 11, and the first plate 112 is longer than the second plate 113; through the attached welded fastening of second board 113 at the inside wall of feeder hopper 11, recycle pivot 111 and play the effect of fixed first board 112, the coal charge is leading-in by feeder hopper 11 after, falls into on first board 112, and first board 112 upset downwards, the coal charge whereabouts of being convenient for overturns to opposite direction once more, gets back to initial position to stop the coal charge of smashing the splash.

Specifically, the outer surface of the first plate 112 is provided with a plurality of vent holes; through the air vent that sets up, the inside circulation of air of coal breaker body 1 of can being convenient for prevents that atmospheric pressure from leading to the inside inflation of coal breaker body 1 too big.

Specifically, the length of the first plate 112 is shorter than the length of the hopper 11; the initial position of first plate 112 is parallel to each other with the feed inlet of feeder hopper 11, because of the length of first plate 112 is shorter than the length of feeder hopper 11 to make partly coal charge fall on first plate 112, because the action of gravity of coal charge, fall and can lead to first plate 112 to overturn downwards on first plate 112, the coal charge falls into coal breaker body 1 along first plate 112 downwards in, first plate 112 blocks that the coal charge directly splashes away by feeder hopper 11.

Specifically, the first plate 112 has a turning angle of 0 to 90 degrees; because first board 112 can overturn through pivot 111, the initial position of first board 112 is parallel to each other with the exit position on the feeder hopper 11, and the coal charge falls back on first board 112, by the action of gravity for first board 112 overturns, and the extreme position that first board 112 overturns downwards is perpendicular to each other with the exit position on the feeder hopper 11, and is parallel to each other with the position of second board 113.

Specifically, a handle 521 is fixedly bonded to the front surface of the storage portion 52; because of the storage part 52 is located the inside wall of stabilizer blade 5, after the coal charge is smashed through the tup, fall by the discharge gate, fall into storage part 52 in, user's accessible handle 521 is pulled out storage part 52, conveniently collects the use to the coal thing of smashing.

The utility model discloses a theory of operation and use flow: after a user moves the utility model to a use place, the coal crusher body 1 is fixedly supported through the support legs 5 and the base 4, an external power supply is turned on, the motor 3 drives the belt to work, the driving wheel 2 is driven to work through the belt, so that the hammer head inside the coal crusher body 1 is driven to work, the first plate 112 is fixed through the second plate 113 welded and fixed in the feed hopper 11, the first plate 112 can be overturned through the rotating shaft 111, when the user guides coal into the feed hopper 11, the falling on the first plate 112 can cause the first plate 112 to overturn downwards due to the gravity action of the coal, the coal falls into the coal crusher body 1 downwards along the first plate 112, the first plate 112 rotates upwards to return to an initial position, at the moment, the hammer head in the coal crusher body 1 works to crush the coal, in the crushing process, the crushed slag is lifted along with the rotation of the hammer head, and part of the crushed slag can be blocked by the first plate 112, the splashing distance of the crushed coal can be lengthened through the protective part 6, the protective part 6 is in a rectangular table shape, a certain blocking effect can be achieved, people are prevented from being accidentally injured, the storage part 52 is fixed through the sliding groove 51 in a sliding mode, people can pull out the storage part 52 through the handle 521, and people can collect the crushed coal conveniently.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
