Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 3: a coal mixing and layering integrated machine comprises a shell 1, wherein a feed inlet 2 is formed in the top of the shell 1, a main roller 3 and an auxiliary roller 4 which are located below the feed inlet 2 and distributed in pairs are arranged in the shell 1, and a plurality of helical blades 21 are equidistantly distributed on the main roller 3 and the auxiliary roller 4 at intervals; the main roller 3 and the auxiliary roller 4 have the same diameter, an included angle of 14-18 degrees is formed between a connecting line between the axes of the main roller 3 and the auxiliary roller 4 and a horizontal plane, a first baffle plate 5 is further arranged in the shell 1 below the main roller 3 and the auxiliary roller 4, a layered main roller 6 and a layered auxiliary roller 7 which are distributed in pairs are arranged below the first baffle plate 5, an included angle of 15-20 degrees is formed between the connecting line between the axes of the layered main roller 6 and the layered auxiliary roller 7 and the horizontal plane, a gate 8 is further arranged above the layered main roller 6, the gate 8 is connected with a chain 9, the chain 9 is supported on a pair of chain wheels 10, one of the chain wheels 10 is coaxial with the worm wheel 11, a gate driving shaft 12 is rotatably supported on the shell 1, a hand wheel 13 is connected on the part of the gate driving shaft 12 which is positioned outside the shell 1, and a worm section 14 meshed with the worm wheel 11 is arranged on the gate driving shaft 12, and a dial 15 is arranged on the outer side of the shell 1, a pointer 16 is rotatably connected at the center of the dial 15, the pointer 16 is arranged at the end part of the shaft where the chain wheel 10 and the worm wheel 11 are arranged,

a sieve plate 17 is further arranged below the layered main roller 6, a combustion grate 18 is arranged below the sieve plate 17, a second baffle plate 19 is arranged below the joint of the layered main roller 6 and the layered auxiliary roller 7, and a third baffle plate 20 is arranged above the sieve plate 17.

The utility model discloses coal mixing layering all-in-one's working process as follows: a large number of coal blocks are stored in the hopper above the feed port 2, the coal blocks can enter the inner cavity of the shell 1 through the feed port 2, the main roller 3 and the auxiliary roller 4 rotate oppositely in the working process, and because the main roller 3 and the auxiliary roller 4 are provided with a plurality of sections of spiral blades 21 which are equidistantly distributed at intervals, when the rollers rotate, the spiral blades 21 can loosen the coal blocks at the bottommost layer and send the coal blocks into a blanking channel between the two rollers, particularly, a certain included angle is formed between a connecting line between the axes of the two rollers and the horizontal plane, and the design can better ensure smooth blanking;

the coal blocks enter the space below the main roller 3 and the auxiliary roller 4 and then fall onto the layered main roller 6 and the layered auxiliary roller 7, the two auxiliary rollers rotate in the same direction, the coal blocks falling on the two auxiliary rollers are conveyed downwards to the combustion grate 18 (the gate 8 is opened in the feeding process), most of the coal blocks fall onto the sieve plate 17 and then are screened in the sliding process on the sieve plate 17, pulverized coal or relatively fine particles fall onto the grate below the sieve plate 17, relatively large coal blocks slide onto the middle part of the combustion grate 18, meanwhile, part of the coal blocks falling from the gap between the layered main roller 6 and the layered auxiliary roller 7 can slide and gather onto the middle part of the combustion grate 18 under the action of the second baffle plate 19, so that the coal blocks can be automatically sorted on the combustion grate 18 according to the volume size, and are more beneficial to full combustion, the combustion efficiency can be effectively improved;

because a connecting line between the axes of the layering main roller 6 and the layering auxiliary roller 7 forms a certain included angle with the horizontal plane, and the first material baffle 5, the second material baffle 19, the third material baffle 20 and the sieve plate 17 are all obliquely arranged (as shown in figure 2), the coal blocks can automatically keep a loose state when falling to the parts, so that the coal blocks finally falling to the combustion grate 18 are not accumulated and agglomerated, and the full combustion of the coal blocks is ensured;

after all the coal blocks enter the device, an operator can drive the gate driving shaft 12 to rotate by rotating the hand wheel 13, the worm section 14 on the gate driving shaft 12 can drive the worm wheel 11 to rotate, the rotating shaft where the worm wheel 11 is located can drive the chain wheel 10 to rotate, and then the driving chain 9 drives the gate 8 to move, so that the closing action of the gate 8 is realized; in the actual working process, because the worm gear has the self-locking characteristic, the mechanism can also control the opening degree of the gate 8 (namely, after the rotating hand wheel 13 is stopped, the gate 8 can hover at the current height), and because the pointer 16 can synchronously rotate when the worm gear 11 rotates, an operator can judge the current hovering height of the gate 8 through the relative position of the pointer 16 on the dial 15, thereby realizing the control of the opening degree of the gate 8.
