Abstract
The utility model discloses a kind of for the grinding roller assembly Gravity support device on flour mill hitch, comprise the plum blossom frame bracing frame that is fixedly installed on the support arm on grinding roller assembly top and is placed in support arm below, between grinding roller assembly support arm and plum blossom frame bracing frame, be provided with spherical support pair, spherical support pair comprises the supporting seat being arranged on plum blossom frame bracing frame, and embed the spheric seating in supporting seat cavity, spheric seating top is provided with the concave surface supporting seat matching with the convex spherical of spheric seating, between the concave surface of the convex spherical of spheric seating and concave surface supporting seat, be slidably connected, the outer edge of concave surface supporting seat extends outside spheric seating.The utility model has the advantage of simple in structurely, amount of parts is few, and production cost is low.Spheric seating be placed in below, concave surface supporting seat be placed in top, without setting up sealing ring, when work, granular material can not enter substantially, due between movement parts without dust, so equipment moving is flexible, effectively extended the service life of equipment.
Description
Technical field
The utility model relates to flour mill, especially relates to a kind of for the grinding roller assembly Gravity support device on hitch between grinding roller of wheat flour-milling assembly and plum blossom frame.
Background technology
Hitch between raymond mill grinding roller assembly and plum blossom frame has adopted the structure of horizontal axis tam vertically being placed to (formation vertical shaft) at present.This structure is divided into two kinds of situations: one is without hermetically-sealed construction, the structure that adopts plum blossom frame vertical shaft hole end surface to place bearing shell and ball, the bearing arrangement of this structure and bicycle is similar, great advantage is to seal, simple in structure, shortcoming is ball rapid wear, and after ball wearing and tearing, easily falls into internal body damage machine; The second is Packed structure, and shortcoming is complex structure, and sealing property shortcoming can cause vertical shaft locking after entering powder.And above-mentioned two kinds of structures all do not have vibration absorber, when work, vibrating noise is very large, contaminated environment.
For above-mentioned defect, apply for the utility model patent of " suspension arrangement between grinding roller of wheat flour-milling assembly and plum blossom frame " applicant and in June, 2014, whole suspension arrangement is realized vibration damping by the shock-reducing sleeve being up and down sleeved on vertical shaft; Born the moment of torsion of integral hanging device by the wear-resistant sleeve in swing arm sleeve and vertical shaft; The secondary gravity that supports grinding roller assembly of spherical support being formed by parts such as spherical support seats.Suspension arrangement after improvement is compared with two kinds of traditional suspension arrangements, with the secondary alternative original ball of spherical support, increased contact area, extended service life, but in practical application, because supporting, the concave surface of spherical support pair is arranged on bottom, if enter powder in the course of work, powder is difficult for discharging, and spherical pair has been accelerated wearing and tearing under the effect of dust, spherical pair is very easily damaged, reduced the service life of equipment.
Summary of the invention
The purpose of this utility model is to provide one both to meet support force, avoid again that powder enters for the grinding roller assembly Gravity support device on flour mill hitch.
For achieving the above object, the utility model can be taked following technical proposals:
Described in the utility model for the grinding roller assembly Gravity support device on flour mill hitch, comprise the plum blossom frame bracing frame that is fixedly installed on the support arm on grinding roller assembly top and is placed in described support arm below, between described support arm and plum blossom frame bracing frame, be provided with the supporting component being slidably matched; Described supporting component comprises the supporting seat being arranged on described plum blossom frame bracing frame, and embed the lower frictional disk in described supporting seat cavity, above described lower frictional disk, be provided with frictional disk, the working face of described lower frictional disk and upper frictional disk is slidably connected.
The working face of described upper frictional disk and lower frictional disk is planar structure.
The working face of described upper frictional disk and lower frictional disk is convex configuration.
The upper surface of described lower frictional disk is the spherical structure raising up, and the lower surface of described upper frictional disk is provided with the inner concave matching with described spherical surface hill.
The outer edge of described upper frictional disk extends outside lower frictional disk.
The utility model has the advantage of simple in structurely, amount of parts is few, and production cost is low.Between upper and lower frictional disk, be slidably connected, without setting up sealing ring, when work, the working face that is convex configuration can ensure that granular material can not enter substantially, even if enter, due to convex surface upwards, under the motion conditions of powder between, also very easily discharge internal body, due between movement parts without dust, so, equipment moving is flexible, has effectively extended the service life of equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of Fig. 1 A portion.
Detailed description of the invention
As shown in Figure 1, 2, described in the utility model for the grinding roller assembly Gravity support device on flour mill hitch, comprise the support arm 1 that is fixedly installed on grinding roller assembly top and the plum blossom frame bracing frame 2 that is placed in support arm 1 below, between grinding roller assembly support arm 1 and plum blossom frame bracing frame 2, be provided with the supporting component being slidably matched; Powder enters on working face when avoiding work, supporting component comprises the supporting seat 3 being arranged on plum blossom frame bracing frame, and embed the lower frictional disk 4 in supporting seat 3 cavitys, and above lower frictional disk 4, being provided with frictional disk 5, the working face of lower frictional disk 4 and upper frictional disk 5 is slidably connected.
When actual manufacture, the working face of upper frictional disk 5 and lower frictional disk 4 can be planar structure.
The utility model is in order better to seal it, the working face of upper frictional disk 5 and lower frictional disk 4 is convex configuration: the upper surface of lower frictional disk 4 is the spherical structure raising up, the lower surface of upper frictional disk 5 is provided with the inner concave matching with spherical surface hill, and the outer edge of upper frictional disk 5 extends outside lower frictional disk 4., when work, plum blossom frame rotarily drives grinding roller assembly taking vertical shaft 6 as centre swinging, and its neutral axis is motionless, and the relative vertical shaft in hole on grinding roller assembly slides, and, between lower frictional disk 4 and upper frictional disk 5, slides meanwhile, and lower frictional disk 4 is static.
