Abstract
The utility model discloses a tool bit of an ice breaker. The ice breaker comprises a rotary drum and a plurality of tool bits are distributed on the outer wall of the rotary drum. Each tool bit comprises a tool bit seat, a column sleeve, a spring, a bullet and a bolt, wherein the tool bit seat is hollow, and one end of the tool bit seat is fixed on the outer wall of the rotary drum; the hollow column sleeve extends into the tool bit seat, and is internally provided with the inner side sections of the spring and the bullet; the inner end surface of the bullet props against the spring, and the outer end of the bullet extends out of the column sleeve and the tool bit seat; the tool bit seat and a copper sleeve are provided with corresponding bole holes; and when the bolt is screwed in the two bolt holes, the inner end surface of the bolt props against the inner side section of the bullet. The bullet, namely the part of the tool bit of the ice breaker, contacted with an ice layer, can be changed conveniently, thereby greatly reducing the manufacturing and using costs of the ice breaker. In addition, the elastic fluctuation of pressure of the bullet on the ice layer can be realized by the spring.
Description
Technical field
The utility model belongs to road ice-breaking device manufacturing technology field, particularly cutter head structure.
Background technology
Icecap comprises a cylinder, fixedly installs a plurality of cutter heads in the outer circle wall of cylinder.But there is following defective in the cutter head structure of existing icecap: during owing to the icecap operation, its cutter head directly acts on ice sheet, through with ice sheet ground bump that ice sheet is broken.Therefore, for icecap, its cutter head is the position of cracky.But, the defective that existence can't be changed after the cutter head breakage of existing icecap.
Summary of the invention
The utility model discloses a kind of cutter head of icecap, the contact site of this cutter head and ice sheet can be changed easily, thereby has reduced manufacturing cost and use cost.
The utility model is taked following technical scheme: the cutter head of icecap, and described icecap comprises cylinder, cylinder outer wall is laid a plurality of cutter heads; Cutter head comprises tool tip, column sleeve, spring, sub warhead, screw, and tool tip is hollow form, and an end is fixed in the outer wall of cylinder; Stretch into the column sleeve of hollow form in the tool tip; Insert the medial segment of described spring and sub warhead in the column sleeve, the described spring of inner face roof pressure of sub warhead, stretch out outside described column sleeve and the tool tip outer end of sub warhead; Tool tip and copper sheathing are offered corresponding screw, and after described screw screwed in described two screws, its inner face roof pressure was in the medial segment of sub warhead.
The cutter head of said icecap is encased inside a bullet pad between the outer wall of screw and tool tip.
The cutter head of said icecap, column sleeve adopts copper sheathing.
The cutter head of said icecap, tool tip and column sleeve all are cylindric, the outer wall matched in clearance of the inwall of tool tip and column sleeve.
The cutter head of said icecap, the inner diameter of sub warhead big slightly and with the inwall matched in clearance of copper sheathing.
The cutter head of said icecap, the outer end portion diameter of sub warhead equates that with tool tip diameter outwards diminishes gradually, external end head is pointed.
The cutter head of the utility model icecap and ice sheet contact site are that sub warhead can be changed easily, thereby have significantly reduced manufacturing cost and use cost.In addition, to be sub warhead can realize elastic floating by spring to the pressure size of ice sheet for cutter head and ice sheet contact site.
Description of drawings
Fig. 1 is the cylinder of icecap and the structure chart of cutter head.
Fig. 2 is the STRUCTURE DECOMPOSITION figure of cutter head.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is elaborated.
As shown in Figure 1, the rotating shaft 2 that stretches through along the axis of cylinder 1, the end face of cylinder 1 is stretched out at the two ends of rotating shaft 2 respectively, rotating shaft 2 and cylinder 1 interlock.The outer circle wall of cylinder 1 is provided with a plurality of cutter heads 3.
Referring to Fig. 2; Cutter head 3 comprises tool tip 31, screw 32, bullet pad 33, copper sheathing 34, spring 35, sub warhead 36, and tool tip 31 is the cylindric of hollow, and its root is fixed in the outer cylindrical wall of cylinder 1; Stretch into the copper sheathing 34 of isometric and hollow cylindrical in the tool tip 31, both matched in clearance.The medial segment of inserting springs 35 and sub warhead 36 is 36-1,36-2 in the copper sheathing 34, the inner 36-1 diameter of sub warhead 36 big slightly and with the inwall matched in clearance of copper sheathing 34, the inner face top pressure spring 35 of sub warhead 36.The outer end 36-3 of sub warhead 36 stretches out outside copper sheathing 34 and the tool tip 31, and the section diameter of this end equates that with tool tip 31 diameter diminishes gradually from inside to outside, and its termination is pointed.Tool tip 31 is screw 31-1,34-1 with the copper sheathing 34 corresponding through holes of offering, and (certainly, tool tip 31 was offered a screw with 34 need of copper sheathing after screw 32 screwed in this two screw; Be that tool tip 31 is offered screw, and copper sheathing 34 is offered through hole, perhaps; Tool tip 31 is offered through hole; And copper sheathing 34 is offered screw, also can realize), its inner face roof pressure is 36-2 in the stage casing of sub warhead 36.Also be encased inside bullet pad 33 between the outer wall of screw 32 and tool tip 31, screw 32 passes this bullet pad 33.The pressure size feedback of 36 pairs of ice sheets of sub warhead realizes elastic floating by spring 35.Since during the icecap operation, its sub warhead 36 direct and ice sheet bumps, therefore, damaged easily.And the structure design through the utility model can be changed impaired sub warhead 36 easily, thereby reduce manufacturing cost and use cost.
More than the preferred embodiment of the utility model is specified; As far as those of ordinary skill in the art; The thought that provides according to the utility model; The part that on the specific embodiment of the utility model and range of application, all can change, these change the protection domain that also should be regarded as the utility model.
