Technical Field
[0001] The utility model relates to the technical field of coal chutes, in particular to a coal chute with a material distribution function. Background Technique
[0002] The coal chute is a general term for the coal conveying pipelines in industries such as coal, ports, thermal power, coal transfer stations, coal washing plants, and coal-fired industrial boilers. The coal chute is a general term for the coal conveying pipelines in industries such as coal, ports, thermal power, coal transfer stations, coal washing plants, and coal-fired industrial boilers.
[0003] The coal chute generally includes components such as a coal dropping hopper, a downcomer, and a diversion trough. For a longer coal chute, an air lock is also required to reduce dust. When diverting, components such as a diversion flap door are also added. The internationally advanced coal chute technology is the IFT technology of inertial transfer. Due to the relatively high cost, it has not been popularized in China.
[0004] However, during the process of using the coal chute to convey coal, the function is relatively single and can only play a transfer function. When conveying coal, due to the uneven size of the coal, it is impossible to carry out material distribution and transportation, resulting in limited use. And during the transportation process, the coal is prone to bump against the inner wall of the pipe, which easily causes the pipe body to be damaged or deformed after long-term use. And during the transportation process, it is impossible to carry out crushing, resulting in the need for reprocessing and crushing into a certain specification for use later, increasing the process and consuming time. Content of the Utility Model

The top side of the installation cylinder is fixedly installed with the feeding plate, and the feeding plate is of an inclined structure.
[0009] Preferably, the material limiting seat comprises a fixing rod, a connecting rod and a material limiting plate. Both ends of the fixing rod are fixedly installed with the connecting rod. The connecting rod is movably installed inside the feeding box through a bearing, and a torsion spring is arranged between the connecting rod and the feeding box. The outer side of the fixing rod is fixedly installed with the material limiting plate.
[0010] Preferably, a plurality of groups of rubber plates are arranged in an annular and equidistant manner on the outer side of the fixing roller. A plurality of groups of grooves are formed on the outer side of the fixing roller. A driving motor is fixedly installed at the front end of the fixing roller.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] First, in the use process of the utility model, coal enters the inside of the feeding box through the feeding plate. At this time, due to the inclined structure of the feeding plate, it is beneficial to facilitate the flow of coal, and then it is convenient to enter the coal dropping pipe for conveying under the circular surface of the installation cylinder. When the coal is fed, the coal contacts the material limiting plate and generates an impact, thereby driving the fixing rod and the connecting rod to rotate, so as to resist the freely falling coal. Then, under the action of the torsion spring, it is convenient for the material limiting seat to reset, which is beneficial to avoid damaging or deforming the inner wall of the feeding box due to impact and improve the service life;
[0015] Second, after the coal enters the buffer chamber, it undergoes a primary buffer through the top side of the buffer plate and the rubber pad. Subsequently, under the impact, the buffer plate moves, and then, under the action of the buffer spring, a reaction force is generated to decompose the impact force, thereby reducing the excessive impact generated by the falling coal and damaging the coal dropping pipe. At the same time, the driving motor drives the fixed roller and the rubber plate to rotate, which is conducive to driving the coal for transportation, avoiding blockage caused by the one-time feeding of coal. Moreover, the rotation of the rubber plate is conducive to avoiding blockage and achieving the effect of unclogging, improving the transportation efficiency. After the coal enters the first conveying box and then the material distribution box, since the first conveying box and the second conveying box are inclined structures, it is conducive to the smooth flow of the material during the falling process and reduces the collision area.
[0016] Third, the coal rolls outside the conveying roller. At this time, the smaller coal flows out through the gap between the conveying rollers and is conveyed by the first material distribution pipe to the lower conveying belt. While the larger coal enters the inside of the crushing box. At this time, driven by the crushing motor, the two gears rotate, and then drive the two groups of crushing rollers to rotate and crush the coal. Then the crushed coal is conveyed by the second material distribution pipe to the lower conveying belt for transportation, which is conducive to the use of material distribution and transportation. At the same time, the larger coal can be crushed during the transportation process, improving the convenience of use and avoiding the need for reprocessing later. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figure 2 , in the figure, a through hole 101 is opened at the right end of the bottom side of the loading box 1, a feeding port 102 is arranged at the upper end of the left side of the loading box 1, and a baffle plate 103 is fixedly installed at the bottom side inside the feeding port 102.
[0029] In this embodiment: The through hole 101 facilitates the transportation and circulation of the coal passing through, and then facilitates the coal to enter the inside of the buffer chamber 4. At the same time, under the action of the baffle plate 103, it is beneficial to prevent the coal from popping out of the loading box 1 during the coal feeding process.
[0030] Working principle: During use, coal enters the inner side of the feeding box 1 through the feeding plate 202. At this time, since the feeding plate 202 is of an inclined structure, it is beneficial to facilitate the flow of coal. Subsequently, it conveniently enters the coal dropping pipe for transportation under the circular surface of the installation cylinder 201. When the coal is fed in, the coal contacts the material limiting plate 303 and generates an impact, thereby driving the fixed rod 301 and the connecting rod 302 to rotate, and then resisting the freely falling coal. Subsequently, under the action of the torsion spring, it is convenient for the material limiting seat 3 to reset, which is beneficial to avoiding damage or deformation caused by impacting the inner wall of the feeding box 1 and improving the service life. When the coal enters the buffer chamber 4, it undergoes a primary buffer through the top side of the buffer plate 6 and the rubber pad 601.

Then, when the coal enters the first conveying box 7 and then enters the material distribution box 8, since the first conveying box 7 and the second conveying box 11 are of an inclined structure, it is beneficial to the convenient flow of the material during the falling process and reduces the collision area. Then, the coal rolls outside the conveying roller 9. At this time, the smaller coal flows out through the gap between the conveying rollers 9 and is conveyed to the lower conveying belt through the first material distribution pipe 10, while the larger coal enters the inner side of the crushing box 12. At this time, driven by the crushing motor 1401, the two gears rotate, thereby driving the two groups of crushing rollers 14 to rotate and crush the coal. Then, the crushed coal is conveyed to the lower conveying belt through the second material distribution pipe 13, which is beneficial to carrying out material distribution for transportation use. At the same time, the larger coal can be crushed during the transportation process, improving the use convenience and avoiding the need for reprocessing later.
