In particular, as shown in fig. 1-10, the tray dispenser 1000 includes a chute frame 100, an upper diverter assembly 200, and a lower diverter assembly 300. Wherein, chute support body 100 includes the cloth chamber, goes up reposition of redundant personnel subassembly 200 and lower reposition of redundant personnel subassembly 300 and sets up on chute support body 100, and the coal material gets into the cloth intracavity from the feed inlet of chute support body 100, then gets into the breaker after the reposition of redundant personnel of reposition of redundant personnel subassembly 200 and lower reposition of redundant personnel subassembly 300 in proper order and carries out the breakage. Because the width of the rotor of the crusher is larger than the width of the coal material entering the chute frame body 100, if the coal material conveyed by the belt is directly sent into the crusher, the working power of the rotor of the crusher cannot be fully utilized, the time for crushing the same coal material is longer, the electric quantity is wasted, and the energy consumption is increased. According to the application, the plate-type distributor 1000 is arranged to jointly distribute materials, and comprises the upper distribution assembly 200 and the lower distribution assembly 300, so that the uniformity of the distribution can be improved, and the energy consumption of the crusher is effectively reduced. The upper flow dividing assembly 200 comprises a first adjusting device 210 and a plurality of first flow dividing plates 220, the first flow dividing plates 220 are arranged at intervals along the width direction of the distribution cavity, and the coal falling onto the flow dividing plates can be sprung out towards two sides by arranging the first flow dividing plates 220, so that the purpose of increasing the width of the coal is achieved. The first adjusting device 210 is disposed on the chute frame 100, and the first adjusting device 210 can adjust the distance between adjacent first diverter plates 220 and the rotation angle of the first diverter plates 220. The staff can flexibly adjust the distance between the adjacent first flow distribution plates 220 and the rotation angle of the first flow distribution plates 220 according to the width of the crusher rotor, so that uniform distribution is ensured, the functions of the crusher rotor are fully utilized, and the purposes of energy conservation and consumption reduction are further achieved. The number of the first diverting plates 220 may be set according to the width of the distribution chamber, and generally, it should be ensured that the distance between the adjacent first diverting plates 220 is not less than 250mm.
In the present embodiment, four first flow dividing plates 220 are provided. The lower flow dividing assembly 300 includes a second adjusting device 310 and a plurality of second flow dividing plates, the second flow dividing plates are disposed in the distribution cavity along the width direction of the distribution cavity at intervals, the second adjusting device 310 is disposed on the chute frame 100, and the second adjusting device 310 can adjust the distance between adjacent second flow dividing plates and the rotation angle of the second flow dividing plates. The number of the second flow dividing plates can be set according to the width of the distribution cavity, and the distance between the adjacent second flow dividing plates is generally not less than 250mm. In this embodiment, the structure of the lower split assembly 300 is the same as that of the upper split assembly 200, so that the time and cost for developing the lower split assembly 300 are reduced while the uniform distribution of the cloth is ensured, and the production cost is low.
Further, with continued reference to fig. 1 to 3, the plate type distributor 1000 further includes an observation window 400, the observation window 400 is disposed at the bottom of the chute frame 100, and a worker can observe the distribution condition through the observation window 400 and correspondingly adjust the first adjusting device 210 and the second adjusting device 310 according to the distribution condition, so that the distribution effect of the plate type distributor 1000 has visibility and quantization capability.
Specifically, the viewing window 400 includes a first frame 410, a drawing riser 420, a second frame 430, and a transparent plate 440. An observation port communicated with the material distribution cavity is formed in the bottom of the chute frame body 100, the first frame body 410 is arranged at the observation port, the drawing vertical plate 420 is slidably connected with the first frame body 410, and the observation port can be opened or closed through drawing the drawing vertical plate 420.

The sealing element 460 can be a rubber pad, the rubber pad has certain flexibility, can be tightly attached to the visible opening and the transparent plate 440 through self deformation, and has good sealing performance.
Preferably, since the coal is ejected after falling onto the first or second diverter plates 220, in order to allow a portion of the coal to fall onto the transparent plate 440 through the viewing port, the contaminated transparent plate 440 has reduced see-through performance, which may affect the operator's viewing structure. Therefore, the side wall of the second frame 430 is provided with the wiping opening 450, so that a worker can wipe one side of the transparent plate 440, which is close to the first frame 410, through the wiping opening 450, thereby ensuring the reliability of the operation of the observation window 400. In order to prevent coal from overflowing the wiping port 450 when the plate-type distributor 1000 is operated, the wiping port 450 may be closed with a cover plate. Alternatively, the shape of the wiping opening 450 may be circular, square, etc., and may be set according to actual needs.

Then, the plate type distributor 1000 is started, the drawing vertical plate 420 is drawn out, and the track of the coal in the distribution cavity is observed through the transparent plate 440. If the cloth is uniform, the drawing vertical plate 420 is enabled to seal the observation port, and the first adjusting device 210 and the second adjusting device 310 do not need to be continuously adjusted. If the cloth is uneven, the first adjusting device 210 and the second adjusting device 310 are adjusted while observing until the cloth meets the requirement, and then the drawing vertical plate 420 is made to seal the observation port.
Preferably, with continued reference to fig. 4, the above-described plate distributor 1000 further comprises a sampling device 500. The sampling device 500 is disposed at the bottom of the chute frame 100, and includes a connection plate 510 and a plurality of material taking grooves 520.
