Abstract
The invention provides a rotor structure of a bark crusher. The rotor structure comprises a main shaft and a rotor sleeving the main shaft, wherein the rotor consists of multiple sets of cutter heads which are connected in series, a cutter blade is installed on the outer side of each set of cutter head, the adjacent cutter heads are sequentially staggered by a certain angle, the cutter blades are arranged in a staggered manner in the axial length of the rotor, and the cutter blades are spirally distributed along the axial direction of the rotor. According to the rotor structure provided by the invention, the cutter blades of the cutter heads are arranged in a staggered manner in the axial length of the rotor, so that raw materials are in segmented contact when being hammered so as to reduce the impact load; and low-carbon steel blade bodies are adopted for the cutter blades, and abrasion-resistant alloy is installed on cutting parts by surfacing welding, so that the hardness is very high, and the cutter blades can be subjected to surfacing welding again after being worn, so that the use cost of a user is greatly saved.
Description
Technical field
The present invention relates to a kind of rotor structure form of pulverizer, particularly relate to a kind of main axle structure that bark can be carried out effectively broken pulverizer.
Background technology
At the equipment of usual process bark, general adopt blade or hammer broken again.When the bark pulverizing that toughness is strong, fiber is long, often there is various problem: 1, bark cannot effectively cut off or hammer into shape broken, be wrapped on blade or tup, the effect that impact is pulverized; 2, the bark do not cut off is wrapped on rotor, can have influence on the dynamic balancing of rotor, the vibration of equipment is increased, easily causes device damage; 3, blade or tup are overall structure, once necessary integral replacing after wearing and tearing, use cost is high; 4, the good bark of toughness is not often smashed completely, and material fiber is pulled on screen cloth, easily causes the blocking of screen cloth, causes the vexed car of equipment.
Summary of the invention
In order to overcome above-mentioned prior art Problems existing, the invention provides a kind of rotor structure of bark grinding mill, overcome easy produced problem in equipment in the past, make desintegrator when processing the material of various character, there is good adaptability, also can reduce vibration and the fault of equipment simultaneously, alleviate the burden of user.
The technical scheme of rotor mill structure of the present invention is: a kind of rotor structure of bark grinding mill, it is characterized in that, comprise: main shaft and the rotor be sleeved on main shaft, described rotor is composed in series by organizing cutterhead more, often organize outside cutterhead and bite is installed, adjacent cutterhead staggers certain angle successively, and described bite is at rotor axial length alternate, and bite distributes along rotor axial curl.
Further, described often group cutterhead is evenly arranged the bite of more than 2 groups or 2 groups.
Further, described many group cutterheads are by Internal hole positioning, and described many group cutterheads are fixed with one by bolt and main shaft.
Further, described bite adopts mild steel cutter hub, and described bite is bolted on cutterhead.
Beneficial effect of the present invention is: knife cutting cutter, at rotor axial length alternate, making raw material segmentation contact when being subject to hammering, reducing shock loading; The cutterhead of some groups is by Internal hole positioning, and described many group cutterheads are fixed with one by bolt and main shaft.Make the extremely simple and easy realization of the processing of rotor; Bite adopts mild steel cutter hub, cutting tip build-up wear-resistant alloy, and hardness is very high, makes bite have good toughness and hardness concurrently, can built-up welding again after bite wearing and tearing, greatly saves the use cost of user.
Accompanying drawing explanation
Fig. 1 is the rotor structure front view of a kind of bark grinding mill that the present invention proposes;
Fig. 2 is the rotor structure side view of a kind of bark grinding mill that the present invention proposes.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail.
See Fig. 1 and Fig. 2, wherein Fig. 1 is the rotor structure front view of a kind of bark grinding mill that the present invention proposes; Fig. 2 is the rotor structure side view of a kind of bark grinding mill that the present invention proposes.
As depicted in figs. 1 and 2, a kind of rotor structure of bark grinding mill, comprise: main shaft 1 and the rotor 2 be sleeved on main shaft 1, described rotor 2 is composed in series by organizing cutterhead more, often organize outside cutterhead and bite 3 is installed, adjacent cutterhead staggers certain angle successively, and described bite 3 is at rotor axial length alternate, and bite 3 distributes along rotor axial curl.
Further, described often group cutterhead is evenly arranged the bite 3 of more than 2 groups or 2 groups.
In the embodiment of the present invention, bite, at rotor axial length alternate, making raw material segmentation contact when being subject to hammering, reducing shock loading.
Further, described many group cutterheads are by Internal hole positioning, and described many group cutterheads are fixed with one by bolt and main shaft 1.Make the extremely simple and easy realization of the processing of rotor.
Further, described bite 3 adopts mild steel cutter hub, and described bite 3 is bolted on cutterhead.
In the embodiment of the present invention, bite adopts mild steel cutter hub, and cutting tip build-up wear-resistant alloy, hardness is very high, and make bite have good toughness and hardness concurrently, bite is connected with cutterhead by bolt, can be convenient for changing after wearing and tearing.Greatly save the use cost of user.
Above to invention has been detailed introduction, but the invention is not restricted to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from present inventive concept.Do not depart from the spirit and scope of the present invention and can make other changes many and remodeling.Should be appreciated that and the invention is not restricted to specific embodiment, scope of the present invention is defined by the following claims.
