The top in putty detection chamber 2 is installed to the mode that putty detecting element 93 accessible hung, and putty detecting element 93 can adopt weight formula material level switch etc. and its principle is: when no putty, putty detecting element 93 is the natural state of drooping, when long-pending material, because the material is with the high lifting of putty detecting element 93, has changed its high position or gesture to the perception putty, as shown in fig. 6, when producing the putty, the vertical state that the putty detecting element 93 that hangs changes the dotted line in the solid line in the drawing shows changes the inclined state that the dotted line shows.

The unloading chute is established the putty and is detected and observe the unloading condition with high definition digtal camera in real time, avoids the bold material to block up and leads to the windrow accident when the discharge opening, avoids 1 card of dummy car to die or tear sealed belt.

According to the invention, air exhaust pipes are arranged at all dust producing points including the front side and the rear side of the blanking chute and the top of the head funnel 35, lengthened sealing covers (namely dust covers) are arranged at the two sides of the air exhaust and dust removal pipes, and the areas where the sealing belts are not tight are covered, so that negative pressure air exhaust is realized, the phenomena of wild air exhaust and dust emission are effectively avoided, and the working point environment is better;

the unloading car 1 realizes reciprocating traveling and unloading, the position of the bin is determined by the proximity switch 61, and the moving distance is determined by the encoder 63, so that the phenomenon of car loss is avoided, real continuous unloading is realized, and the utilization rate of the bin is improved.

The material buffer 28 is arranged at the top of the discharging chute, so that the material speed can be reduced, and the abrasion of the top of the discharging chute can be avoided. Detachable support door plant and collection material platform are established to unloading chute vertical section 2b both sides, effectively improve the chute life-span, reduce chute secondary repair work volume.

Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
