Description

Material discharger

Technical Field

The utility model belongs to the technical field of engineering machinery, and particularly relates to a discharger.

Background

The pavement milling machine is widely applied to road maintenance construction as a road machine. The milling drum is an important working device in a milling machine, and the milling rotor is the core of the milling machine and consists of a milling rotor shaft (roller), a cutter holder and a cutter head, wherein the cutter head comprises a throwing plate. The milling cutters which are arranged in a spiral structure rotate at a high speed through the transmission device, the general rotation direction is consistent with the advancing direction of the wheels, and the milling cutters are directly contacted with the ground, so that the purpose of milling the road surface is achieved.

The cutter heads are spirally distributed from two sides to the middle and are used for gathering the waste materials to a plurality of material throwing plates in the center so as to be sent to a material collecting device, and the material throwing plates are positioned between milling cutters; in the milling process, the materials are planed by a milling cutter, and then are thrown to a conveying belt through a throwing plate and then are conveyed to a loading truck in a concentrated mode. It follows that the milling load of the road surface is calculated in kilometers, and the waste generated by the milling drum cutting the road surface is calculated in tons, so that the wear speed of the flitch is extremely high under the long-time and heavy-load working condition. The work of disassembling the scrapped flitch is generally tedious and heavy, and the work is stopped, so that the construction efficiency is reduced, and the construction cost is increased. It would be of great benefit to eliminate the aforementioned adverse effects if a long life throwing plate could be designed.
