Abstract
The invention discloses a rotating type anticlogging coal device, which consists of a fixed grid plate arranged above a dialing coal machine with a slope. A first screen hammer and a second screen hammer are arranged at the middle of the fixed grid plate, wherein, the first screen hammer and the second screen hammers are arranged on the rotating screen shaft; an angle Alpha between the fixed grid plate and a horizontal plane is 0 to 20 degrees. The device provided by the invention has the advantages of reasonable design, rather high crushing and screening capacity, wear resistance and shock resistance, and has the advantage that coal is not easily stuck.
Description
Technical field
The present invention relates to a kind of coal and load facility, particularly a kind of rotary type block-resistant comb device for coal.
Background technology
The comb device for coal is a part that is widely used in a kind of equipment-tippler of unloading coal of thermal power plant.The coal that is got off by the tippler dumping is transported to specified point by comb device for coal, group coal machine and belt conveyor with coal.The tippler comb device for coal of each thermal power plant generally uses the grating type vibratory sieve at present.In actual production, the vibration telescoping mechanism of flase floor lower end often is subjected to the obstruction of coal and flase floor can not be playbacked fully in vibration processes, if things go on like this long-pending coal in flase floor lower end is more and more, cause the flase floor vibration to be lost efficacy, oscillating grid has become stationary grizzly, and its consequence is that coal that dumping gets off often is blocked on the compass screen surface (especially with wet coal and to freeze coal common), has to use a large amount of manually clearing up, not only reduce production efficiency, also wasted great amount of manpower and material resources simultaneously.
Summary of the invention
The objective of the invention is deficiency, a kind of rotary type block-resistant comb device for coal with higher fragmentation and sieving capacity and wear-resisting, shock-resistant and difficult sticking coal is provided at the prior art existence.
Technical scheme of the present invention is: a kind of rotary type block-resistant comb device for coal, comprise and be erected at the fixed grating screen of dialling coal machine top and having the gradient, it is characterized in that: the centre that is positioned at the fixed grating screen is provided with a sieve hammer and No. two sieve hammers, and a described sieve hammer and No. two sieve hammers are installed on the sieve axle of rotation; The angle α of described fixed grating screen and horizontal plane is 0～20 °.
The present invention compared with prior art has the following advantages:
(1) the present invention is reasonable in design, novel structure, and the sieving capacity height is to wet coal and to freeze the dumping of coal effective;
(2) has higher breaking capacity;
(3) foreign material of can pulverizing and wear and tear;
(4) wear-resisting, shock-resistant, be difficult for sticking coal;
(5) stone can be rolled to flase floor, be convenient to cleaning.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the present invention includes and be erected at the fixed grating screen 1 of dialling coal machine top and having the gradient, the centre that is positioned at fixed grating screen 1 is provided with 2 and No. two sieve hammers 3 of a sieve hammer, and 2 and No. two sieve hammers 3 of a described sieve hammer are installed on the sieve axle of rotation; Described fixed grating screen 1 is 0～20 ° with the angle α of horizontal plane.
Described sieve axle is for being connected with the active sieve axle 4 of motor 6.
Initiatively the axis direction of sieve axle 4 is vertical with the gradient direction of fixed grating screen 1.
As shown in Figure 3 and Figure 4, the axis direction of described active sieve axle 4 is consistent with the gradient direction of fixed grating screen 1.
As shown in Figure 5 and Figure 6, described sieve axle comprises sieve axle 4 initiatively and and the driven sieve that be rotationally connected parallel by transmission mechanism and sieve axle initiatively 4 spools 5.Initiatively sieve axle 4 is vertical with the gradient direction of fixed grating screen 1 with the axis direction of driven sieve axle 5.
Described transmission mechanism comprises the sprocket wheel 7 that is arranged on initiatively the sieve axle 4 and driven sieve axle 5 and the chain 8 of the sprocket wheel 7 that is rotationally connected.
As shown in Figure 7 and Figure 8, described active sieve axle 4 is consistent with the gradient direction of fixed grating screen 1 with the axis direction of driven sieve axle 5.
As Fig. 9 and shown in Figure 10, a described sieve hammer 2 comprises and being used for and hammer cover 9 that described sieve axle is connected, be positioned on the cylindrical of hammer cover 9 to be connected with hammer dish 10, along the circumference of hammer dish 10 radially, be arranged at intervals with long tup 11 and weak point tup 12.
As Figure 11 and shown in Figure 12, described No. two sieve hammers 3 comprise and being used for and hammer cover 9 that described sieve axle is connected, be positioned at hammer and overlap on 9 the cylindrical and be connected with hammer dish 10, along the circumference of hammer dish 10 radially, five equilibrium is provided with a plurality of cutting teeths 13.
When the present invention worked, motor 6 drove the rotation of sieve axle or drives the rotation of sieve axle by transmission mechanism, was provided with sieve hammer (comprising 2 and No. two sieve hammers 3 of a sieve hammer) with mode at a certain distance on the sieve axle, and the sieve hammer imports the below with coal and dials the coal machine in rotary course.The sieve hammer also has broken coal cinder, wooden unit when leading coal, rub effects such as straw rope and removing foreign material.
