Abstract
The utility model discloses a shovel blade of a Raymond mill. The shovel blade comprises a shovel blade seat and a shovel blade arranged at the front end of the shovel blade seat, wherein a connecting mortice is formed in the front end of the shovel blade seat; the front blade face of the shovel blade inserted into the connecting mortise is in flat connection with the front blade face of the shovel blade seat; a positioning pin hole is formed in the position where the bottom of the shovel blade seat extends towards a shovel blade body; a positioning pin is arranged in the positioning pin hole; a ring-shaped groove is formed in the part, of the shovel blade seat, at the tail part of the positioning pin; a check ring is arranged in the ring-shaped groove. The shovel blade has the advantages that the structure is simple; the mounting and the replacement are convenient; as the shovel blade seat and the shovel blade are connected through the mortise, and are fixed through the positioning pin, the front blade face can be flat so as to ensure the resistance is small when a material passes through the shovel blade; meanwhile, in the use process, the shovel blade has low possibility of loosening, and the replacement of a worn shovel blade is convenient and quick.
Description
Technical field
The utility model relates to flour mill, especially relates to a kind of raymond mill perching knife.
Background technology
Connection in tradition raymond mill between perching knife (head) and shovel seat and be fixedly by bolt or rivet.Major defect is always to have the counterbore of rivet or bolt to cause rake face out-of-flatness at the rake face of perching knife, in the time that material passes through, increases resistance; And bolt connects in using easily loosening, and while connecting with rivet, if change inconvenient after perching knife wearing and tearing.
Summary of the invention
The utility model object is to provide a kind of and changes conveniently, is difficult for loosening raymond mill perching knife.
For achieving the above object, the utility model can be taked following technical proposals:
Raymond mill perching knife described in the utility model, comprise shovel seat and the perching knife that is arranged on described shovel seat front end, offer connection tongue-and-groove at described shovel seat front end, insert and connect the rake face of perching knife in tongue-and-groove and the rake face of described shovel seat is smooth is connected, offer dowel hole from described shovel seat bottom to extending on described perching knife cutter hub, in described dowel hole, be provided with alignment pin, on the shovel seat of described alignment pin afterbody, offer annular groove, in it, be provided with back-up ring.
Simple in structure, installation replacing convenience that the utility model advantage is.Shovel seat is connected by tongue-and-groove with perching knife, and fixes by alignment pin, make rake face smooth, when material passes through, resistance is little; And in use procedure, be difficult for becoming flexible, after wearing and tearing, change perching knife convenient and swift.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, raymond mill perching knife described in the utility model, comprise shovel seat 1 and the perching knife 2 that is arranged on shovel seat 1 front end, offer connection tongue-and-groove at shovel seat 1 front end, insert the rake face of perching knife 2 and smooth linking of rake face of shovel seat 1 that connect in tongue-and-groove, offer dowel hole from shovel seat 1 bottom to extension on perching knife 2 cutter hubs, in dowel hole, be provided with alignment pin 3, on the shovel seat 1 of alignment pin 3 afterbodys, offer annular groove, in it, be provided with back-up ring 4.
The double action that connects tongue-and-groove and alignment pin can prevent coming off of perching knife 2, the smooth linking of rake face of the rake face of perching knife 2 and shovel seat 1, can reduce material by time resistance, in the time that perching knife 2 uses certain hour to occur that wearing and tearing need to be changed, take off back-up ring 4, exit alignment pin 3, perching knife 2 can be taken off and changes, very convenient.
