The specific embodiment

Consult Fig. 1, Fig. 2, the utility model comprises spindle drum 1, cutter drum frame 2, cutter drum 3 and outer cover 4, described spindle drum 1 is made up of axle bed body 11, final drive shaft 12 and knife rest gear 13, axle bed body 11 is established collar bush 14, outer in being and is axially arranged with and

tops bar

15 and 16 the hollow step axle of getting out of a predicament or an embarrassing situation, final drive shaft 12 in bearing is located at collar bush 14 and two ends stretch out, knife rest gear 13 be located at axle bed body 11 outsides with get out of a predicament or an embarrassing situation 16 fixing; Described cutter drum frame 2 by a collar bush 21 form with several cuttves drum axle sleeves 22, collar bush 21 vertical settings, several the bulging axle sleeves 22 of cuttves are horizontally disposed with and are connected in radially collar bush 21 bottoms; Described cutter drum 3 is several, every by drum axle 31, drum 32, cutter shaft 33, cutter drum gear 34 and milling blade 35 compositions, described drum 32 is two disks, cutter shaft 33 is several, cutter shaft 33 is circumferentially between two drums 32 and fixedly connected, milling blade 35 is set with on cutter shaft 33, and drum axle 31 1 ends are located at two drums, 32 centers of circle and fixedly connected, and cutter drum gear 34 is located at drum axle 31 middle parts;

The collar bush 21 of described cutter drum frame 2 is loaded on the following elongated end of final drive shaft 12 and is connected with final drive shaft 12 keys; Drum axle 31 other ends of described several cutter drums 3 are located at cutter respectively through bearing and are roused in the axle sleeve 22 and

cutter drum gear

34 and 13 engagements of knife rest gear; 15 fixedly connected with topping bar in axle bed body 11 outsides that described outer cover 4 is located at spindle drum 1, outer cover 4 is provided with suction port 41;

It is radial that described cutter drum frame 2 is set to " one " word, " people " word or " ten " word by two, three or four cutter drum axle sleeves 22; Described milling blade 35 endoporus and cutter shaft 33 are matched in clearance.

The utility model is to use like this:

Consult Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model is fixed on the frame of milling machine by spindle drum 1, the motor of milling machine or hydraulic motor connect final drive shaft 1, during work, because rousing the collar bush 21 of frame 2, cutter is connected, therefore with final drive shaft 12 keys, cutter drum frame 2 rotates synchronously with final drive shaft 12, several cutter drums 3 in cutter drum axle sleeve 22 on the cutter drum frame 2 and the cutter drum axle sleeve 22 also rotate synchronously with final drive shaft 12, and at this moment, the rotation of cutter drum 3 is referred to as the revolution of cutter drum 3; In 3 revolution of cutter drum, because

cutter drum gear

34 and 13 engagements of knife rest gear, knife rest gear 13 drives cutter drum gear 34 and rotates, cutter drum gear 34 drives drum axle 31, drum 32 rotates synchronously, at this moment, the rotation of cutter drum 3 is referred to as the rotation of cutter drum 3, and cutter drum 3 is the milling work of finishing the abutment face that satisfies the need under the composite rotation state of revolution and rotation.

Consult Fig. 4, Fig. 8, because milling blade 35 endoporus and cutter shaft 33 that the utility model is loaded on the cutter drum 3 are matched in clearance, be that milling blade 35 is set on the cutter shaft 33, the rotation of milling blade 35 is not subjected to the restriction of cutter shaft 33, milling blade 35 is contained on the cutter shaft 33 for several pieces blade strings, pad is housed between the blade, the abutment face that satisfies the need is implemented in the process of milling work, by the contact degree of depth of adjustment spindle drum 1 adjusting milling blade 35 with ground, when string is contained in milling blade 35 blades on the cutter shaft 33, when rotating kiss the earth with cutter drum 3, what milling blade 35 blades satisfied the need the generation of abutment face is a kind of impact and impact, the active force that this impact and impact produce basal plane, be similar to of the impact of shot-blasting machine shot to basal plane, because the quality of milling blade 35 is much larger than the quality of shot, therefore, the momentum that the utility model produces under identical linear velocity, momentum much larger than the shot-blasting machine shot, the disposal ability of abutment face of satisfying the need is stronger, because being a kind of impact, its processing of satisfying the need the abutment face cuts but not the rigidity cutting, in processing procedure, can effectively remove the laitance part of road and bridge basal plane, and can not cause loose damage stone aggregate.

Consult Fig. 5, Fig. 6, Fig. 7, it is radial that cutter of the present utility model drum frame 2 is set to " one " word, " people " word or " ten " word by two, three or four cutter drum axle sleeves 22, therefore, can be combined to two, three or four the utility model that cutter drum 3 is formed, select to use for different demands.

Consult Fig. 1, Fig. 9, two of the present utility model, three or many spindle drums 1 are set up in parallel on frame, can realize the combination of two stations, three stations or multiplex's bit-type different type of machines.

Consult Fig. 1, Fig. 5, Fig. 6, Fig. 7, Fig. 9, for implementing civilized construction, the utility model is provided with outer cover 4 on spindle drum 1, and outer cover 4 is provided with suction port 41, when the cutter drum 3 abutment face that satisfies the need carries out milling when work, the dust that accumulates in the outer cover 4 is absorbed by dust catcher through suction port 41.

The hair construction was cut a hole on the surface when the utility model also can be used for bridge cement bridge pier and hydraulic engineering reinforcing, selected for use different milling blades 35 also can construct except that the slurry rust cleaning to surperficial enforcement of steel work.
