Abstract
The utility model discloses a material bowl base plate for a sealed crusher. By the material bowl base plate, bolts for connecting the material bowl base plate cannot be broken easily. The material bowl base plate comprises a group of bolt holes which are arranged along the circumferential direction of the material bowl base plate, wherein the bolt holes are formed in the material bowl base plate; the centers of the bolt holes are positioned on the same positioning circumference; and a central angle which corresponds to a circular arc between the centers of every two adjacent bolt holes on the positioning circumference is 18 to 80 degrees. The ratio of the diameter of the material bowl base plate to the diameter of the bolt holes is 5-4. The size and layout of the bolt holes are relatively reasonable, so that the corresponding bolts for connecting the material bowl base plate are reasonably stressed, and cannot be broken easily; and therefore, the long-term and stable operation of the sealed crusher is facilitated.
Description
Technical field
The utility model relates to a kind of material alms bowl chassis that is used for sealed pulverizer.
Background technology
In the prior art, be connected with material alms bowl chassis through bolt on the sealed pulverizer, material alms bowl chassis is provided with one group of bolt hole along the circumferential setting on material alms bowl chassis, and the hole heart of each bolt hole is positioned on the circumference of same location.There is following deficiency in use in above-mentioned material alms bowl chassis: because the design of the bolt hole on material alms bowl chassis is reasonable inadequately, sealed pulverizer is used to connect the bolt of expecting the alms bowl chassis and often ruptures in use.
The utility model content
The technical problem that the utility model solves provides a kind of bolt material alms bowl chassis of the sealed pulverizer of easy fracture not that connects material alms bowl chassis that is used in.
The utility model solves the technical scheme that its technical problem adopted: the material alms bowl chassis of sealed pulverizer; Comprise the one group of bolt hole that circumferentially is provided with along material alms bowl chassis that is arranged on the material alms bowl chassis; The hole heart of each bolt hole is positioned on the circumference of same location, and the central angle that the circular arc between the hole heart of adjacent two bolts hole on the circumference of said location is corresponding is that 18 degree are to 80 degree.
Further be: the diameter on said material alms bowl chassis and the diameter ratio of bolt hole are 5～4.
Further be: the diameter of said bolt hole is 12 millimeters.
Further be: said one group of bolt hole circumferentially is uniformly distributed with along material alms bowl chassis, and the central angle that the circular arc between the hole heart of adjacent two bolts hole on the circumference of said location is corresponding is 18 degree.
The beneficial effect of the utility model is: because the size and the layout of bolt hole are comparatively reasonable, make to be used to connect the bolt strained reasonable of material alms bowl chassis accordingly that easy fracture does not help the running steady in a long-term of sealed pulverizer.
Description of drawings
Fig. 1 is the sketch map on material alms bowl chassis of the sealed pulverizer of the utility model.
Be labeled as among the figure: material alms bowl chassis 2, bolt hole 1.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified.
As shown in Figure 1; The material alms bowl chassis of sealed pulverizer; Comprise the one group of bolt hole 1 that circumferentially is provided with along material alms bowl chassis that is arranged on the material alms bowl chassis 2; The hole heart of each bolt hole is positioned on the circumference of same location, and the central angle that the circular arc between the hole heart of adjacent two bolts hole on the circumference of said location is corresponding is that 18 degree are to 80 degree.Adopt said structure; Can make the quantity of the bolt hole on the material alms bowl chassis remain on a reasonable interval; And the relation of the position between each bolt hole is reasonable in design, through evidence, is used to connect the reasonable stress of each bolt of expecting the alms bowl chassis; Easy fracture can not guarantee that sealed pulverizer runs well for a long time.
In order further to improve the force-bearing situation of above-mentioned each bolt, the diameter on said material alms bowl chassis 2 and the diameter ratio of bolt hole 1 are 5～4.For example, generally between 60 millimeters to 48 millimeters, then the diameter of the bolt hole on it is preferably 12 millimeters to the diameter on material alms bowl of the prior art chassis 2.
On the basis of the above, in order further to improve the force-bearing situation of above-mentioned each bolt, said one group of bolt hole 1 circumferentially is uniformly distributed with along material alms bowl chassis, and the central angle that the circular arc between the hole heart of adjacent two bolts hole on the circumference of said location is corresponding is 18 degree.
