Description

The wear-resisting cutter drum that a kind of drum chipper uses

Technical field

The utility model relates to a kind of cutter drum of drum chipper, is specifically related to the wear-resisting cutter drum that a kind of drum chipper uses.

Background technology

Drum chipper is the special equipment of preparation wood chip, is widely used in paper mill, particieboard factory, fibre-board plant and Chip Production base.It can cut into log, brush wood, undersized log etc. the industrial wood chip of certain specification; Drum chipper partly is made up of frame, cutter drum, feed roller group, case, electric-control system etc.Compact overall structure is reasonable, and is easy and simple to handle, and production capacity is big, and adaptability to raw material is strong, is the ideal equipment of production high-quality wood chip.

The drum chipper operation principle is that motor drives the rotation of cutter drum by belt transmission, and the cutter drum is gone up fixedly fly cutter, and when log was delivered to the cutter drum by the feed roller group, the cutter drum of rotation was gone up will chipping to log of fly cutter, produces the industrial wood chip that needs.

Be illustrated in figure 1 as existing cutter drum structure, this cutter bulge is drawn together and is interconnected some circumferential uniform liner plates 7 and some circumferential uniform fly cutter supporting seats 1 and the end plate 10 that is fixed on liner plate 7 two ends, the center of end plate 10 offers axis hole 11, wherein each fly cutter supporting seat 1 is connected between adjacent two blocks of liner plates 7, is being installed on the fly cutter loading end 9 of fly cutter supporting seat 1 by pressure knife block 6 and fly cutter hold-down bolt 8 on each fly cutter supporting seat 1.Place adjacent with fly cutter supporting seat 1 on the liner plate 7 of cutter drum also offers arc milling groove 3, and the chamfered portion 2 of fly cutter supporting seat 1 outer end flushes with arc milling groove 3 inner surfaces, constitutes cutting slot 5 jointly; When cutter drum rotation, fly cutter 4 cutting timber are cut the timber section of getting off and stay in the cutting slot 5 of cutter drum and the cutter drums that are rotated are transported to discharging opening.

Cutter drum length time service, timber scratch cutting slot 5 inner surfaces are worn it, especially chamfered portion 2 wearing and tearing of the fly cutter supporting seat 1 of fly cutter 4 belows are more severe, just need the fly cutter supporting seat 1 to being worn to dismantle, change when its wearing and tearing acquire a certain degree.And the cutter drum is the core component of entire machine, and the workload of changing fly cutter supporting seat 1 is very big, pressure knife block 6 and the fly cutter 4 on the cutter drum need be unloaded, and could change fly cutter supporting seat 1, and having spent bigger manpower and materials can finish;

Moreover the expense that replacing fly cutter supporting seat 1 produces is higher, and the fly cutter supporting seat can make the whole production cost raise greatly than weak point 1 service life.

In addition, existing leading offers the mounting hole 12 that passes for cutter hold-down bolt 8 on the bulging fly cutter 4, fly cutter 4 is regulated the blade position by the adjusting bolt 13 at its rear portion, the blade of all fly cuttves 4 all is on the same circumference 14, when causing the blade of fly cutter 4 to contact with log, this mounting means is hard contact, tipping easily.

The utility model content

The purpose of this utility model is that the wear-resisting cutter that provides a kind of drum chipper to use rouses, and it carries out Wear-resistant Treatment by the tool setting drum, has overcome the not wear-resisting shortcoming of existing chipper drum machine knife drum, thereby has realized the purpose of this utility model.

The technical problem that the utility model solves can realize by the following technical solutions:

The wear-resisting cutter drum that a kind of drum chipper uses, comprise and interconnect some circumferential uniform liner plates and some circumferential uniform fly cutter supporting seats and the end plate that is fixed on the liner plate two ends, the center of end plate offers axis hole, wherein each fly cutter supporting seat is connected between adjacent two blocks of liner plates, is being installed in by pressure knife block and bolt on each fly cutter supporting seat on the fly cutter loading end of fly cutter supporting seat; The place adjacent with the fly cutter supporting seat also offers the arc milling groove on the liner plate of cutter drum, it is corresponding to arc milling slot length direction the one wearing plate installed surface that sink to be set at the chamfered portion of fly cutter supporting seat outer end, and on the fly cutter supporting seat, offer the oblique wearing plate installation ladder hole of a row corresponding to described wearing plate installed surface vertical direction, in installing ladder hole, places each wearing plate a wearing plate set bolt, described wearing plate set bolt is threaded with wearing plate, wearing plate is installed on the described wearing plate installed surface, and the wearing plate surface is flushed with arc milling groove inner surface, constitute cutting slot jointly.

The beneficial effects of the utility model are:

Do not influencing under the working angles situation, protecting the fly cutter supporting seat in the cutter drum not frayed, just protecting whole cutter drum not to be worn, prolonging the service life of whole cutter drum effectively, saving manpower and materials, simple and practical, highly versatile.Because fly cutter is provided with pressure knife block and plays bolt and butterfly spring surely, when tool changing, butterfly spring, is convenient to take apart with pressure knife block jack-up by spring base in addition.
