By adopting the technical scheme: firstly, in order to prevent the coal from scattering outside the conveying device when the coal is conveyed by the conveying device, carding assemblies for carding the coal are arranged on two sides of the conveying device, so that most of the coal is kept at the central position of the conveying device when the coal is conveyed, and the coal is prevented from scattering; meanwhile, a conveying device for receiving the coal discharged from the conveying device is arranged below the output end of the conveying device, the conveying device can smoothly convey the coal to a coal using area, and can effectively screen massive coal with large volume in the slurry coal, so that qualified coal is conveyed to the coal using area, unqualified coal is uniformly collected into a to-be-transferred area to be further crushed, and the use efficiency of the coal is ensured to a certain extent;

in more detail:

1. working principle of the carding assembly: through the stand as supporting (the stand can be fixed subaerial), because each carding plate extends to conveyor's direction respectively, so when the coal charge moved on conveyor, partial coal charge can strike with the carding plate, because the carding plate passes through the spacing activity of shock attenuation module axial on the stand, therefore, the carding plate can comb partial coal charge, makes most coal charge carry the removal (namely: move in the interval between the carding plate that corresponds) at conveyor's center to reach the carding effect to the coal charge, its principle is: when the carding plate is contacted with the conveyed coal and impacted by the coal, the carding plate is stressed, because the carding plate is fixedly connected (for example, welded) with the column sleeve, the column sleeve rotates axially on the basis of the column sleeve when stressed, and because the damping module is arranged on the matching surface of the column sleeve and the column sleeve, when the column sleeve rotates, the damping block fixedly connected with the column sleeve can transmit the acting force generated when the column sleeve rotates to the damping spring, and the damping spring is continuously stressed and generates complex elasticity to enable the carding plate to reciprocate in a trace interval, thereby achieving the carding effect on the coal and avoiding the coal from scattering outside the conveying device;

2. the working principle of the transportation device is as follows: when the coal material moves to the output end of the conveying device, the coal material is discharged from the conveying device and falls onto a screening conveying belt below the conveying device, when the coal material is conveyed on the screening conveying belt, the coal material with the size smaller than the screening opening falls onto a first conveying belt, the coal material with the size larger than the screening opening stays on the screening conveying belt, the coal material with the larger size falls into a coal storage box arranged at the free end of the coal storage box through the output end of the screening conveying belt for storage, the coal material is waited for subsequent further crushing, after the coal material with the smaller size falls onto the first conveying belt, the coal material is conveyed to the output end of the screening conveying belt through a material pouring plate arranged in a material pouring cavity, the coal material can be guided to the end face, close to the first conveying belt, of the screening conveying belt, falls onto a second conveying belt through the screening opening again, and is conveyed to a coal material using area through the second conveying belt;

it should be noted that: firstly, in order to prevent the coal from falling onto the second conveying belt and scattering outside the second conveying belt due to the inertia of the coal, material blocking plates can be arranged on two sides of the second conveying belt; second, for guaranteeing the coal charge on the screening conveyer belt can be smoothly through the screening mouth, its top at the screening conveyer belt is equipped with combs the subassembly and is equipped with the homogenizing board in the material pouring intracavity, and its effect is: when the coal is transported on the screening conveyor belt, the uniform material plate and the carding assembly can enable the coal and the screening conveyor belt to generate 'opposite motion' as a reference object, and enable the coal to effectively complete the screening purpose through the screening opening, and the carding assembly can effectively assist the screening conveyor belt to complete the screening function and cannot affect the conveying of the coal with larger size of the screening conveyor belt; third, the dislocation set of each row of screening mouth can guarantee to screen the screening effect of conveyer belt to the coal charge, promptly: the conveying direction of the screening conveying belt is taken as a reference, and screening openings are formed in different conveying lines, so that the screening effect on the coal can be effectively improved; fourthly, because the coal material is special in material, in order to prevent the coal material from damaging the screening opening, a metal reinforcing frame is arranged at the screening opening (the metal reinforcing frame can be fixedly connected with the inner wall and the edge of the screening opening through nails); fifthly, the depressed area is arranged in the peripheral area of the edge of the screening opening close to the first conveying belt, so that the efficiency of discharging the coal in the material pouring cavity onto the second conveying belt can be improved; sixthly, the material pouring plate can prevent the coal material from being discharged from the screening port at the turning position of the material pouring cavity, and can effectively guide the coal material to the middle part of the lower area of the material pouring cavity, so that the coal material can smoothly fall onto the second conveying belt; seventh, the hard rubber, as a material used for the conveyor belt in the fields of building, building materials and the like, can have certain flexibility, ensures smooth operation of the screening conveyor belt, also has certain hardness, and can smoothly bear the coal.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
