Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 to 3, a milling drum for preventing material accumulation in the drum comprises a milling drum 1, a plurality of milling cutters 2 for milling damaged road surfaces are mounted on the outer side wall of the milling drum 1, the inner end of the milling drum 1 is connected with a speed reducer 3, the milling drum is mounted in a milling chamber of a milling machine through the speed reducer 3, and a discharge protection element is fixedly mounted in the milling drum 1.
After milling drum cylinder 1, speed reducer 3 and installing in the storehouse of milling of current milling machine back, can pneumatic complete machine equipment make its operation mill and mill drum cylinder 1 and mill the plane to the damaged road surface, mill the waste material that gets off at the in-process of milling and dig and can enter into the cylinder of milling and dig the drum through the clearance inside, owing to inside is provided with row's material protection piece, the rotatory milling and dig drum cylinder 1 of cooperation that can be quick discharges the waste material. Whole process can go on milling and planing 1 normal during operation of drum cylinder, does not influence its normal work and can be quick again discharge the waste material fast simultaneously, splashes outside the inside waste material of cylinder can push out the drum of milling and planing the drum under the effect of the gravity of waste material itself and the resultant of the thrust of spiral plate, avoids the waste material to bond the overstock in the drum, and then the dynamic balance of the during operation of milling and planing drum is influenced.
Preferably, the discharge guard comprises a striker plate 4 fixedly mounted on the inner wall of the milling drum 1.
The striker plate 4 can lead out internal waste.
Preferably, the discharge guard has several striker plates 4 which are uniformly distributed along the circumference of the inner cavity of the milling drum 1 and are fixedly mounted on the inner wall of the milling drum 1.
The arrangement of the plurality of material baffle plates 4 (preferably 4) can better discharge waste materials, and the material discharging efficiency is improved.
Each striker plate 4 is welded in the inner cavity of the milling drum roller 1, the inner end of each striker plate is positioned between the cylindrical surface of the speed reducer 3 and the inner cylindrical surface of the roller of the speed reducer 3, and the outer end of each striker plate is positioned close to the outer port of the milling drum roller 1.
