In actual operation, the driving chain 6 is two relatively horizontal upper chains and lower chains, the stress of the upper chains and the lower chains is unequal, the lower chains are stressed under normal conditions, the upper chains are not stressed, and if the stress of the actual chains exceeds the safety load when the driving chain 6 is designed, the chain breakage accident can be caused. If a plurality of scrapers 3 are mounted on the chain, a dynamic model needs to be built in principle, and the dynamic tension characteristics and the resistance coefficient change relation of the scrapers 3 under different speeds and resistances are given so as to ensure that the scrapers 3 stably act on the materials in the feeding channel 2.
In order to ensure that the scraper 3 is more stable under the action of the transmission chain 6, the mechanism further comprises a guide rail 4 and a guide rod 5, wherein the guide rail 4 is a non-magnetic metal guide rail, the guide rod 5 is a stainless steel guide rail with higher hardness, and the scraper 3 is supported by the guide rail 4 and the guide rod 5, so that the torque generated by unbalanced plane stress of the scraper 3 can not influence the transmission chain 6, and the condition that the load deviation of the transmission chain 6 is overlarge is effectively avoided.
When scraper 3 carries out the propelling movement to different waste materials quality, because scraper 3 quantity is less, the stress point of drive chain 6 also relatively reduces, drive chain 6 usually only need guarantee tensile stability can, through reducing scraper 3 quantity, avoid the load change when a plurality of scrapers 3 are synchronous to influence drive chain 6, adopt single scraper blade to need not accurately calculate every scraper 3 in the circumstances of the multiple stress state of chain system, through the load dynamic characteristic change risk that avoids a plurality of scrapers 3 simultaneous working, be favorable to the reduction of the load deviation risk of drive chain 6, the atress controllability of whole drive chain 6 is higher.
