Abstract
The utility model relates to a fixing structure for a pin shaft of a grinder in the field of feed machinery. The fixing structure comprises a pin shaft which vertically passes through a plurality of parallel hammer frame plates; a plurality of spacer bushes are sleeved on the pin shaft arranged between the adjacent hammer frame plates; hammer plates are sleeved between the adjacent spacer bushes on the pin shaft; two ends of the pin shaft extend out of the hammer frame plates; radial through holes are formed at two ends of the pin shaft extending out of the hammer frame plates; a ring groove is formed at the periphery of the pin shaft with the same cross section as the through hole; a cotter pin is inserted in the through hole and comprises a straight section and an arc section fitted with the radian of the ring groove; the straight section and the arc section are in bending transitional connection; the straight section penetrates into the through hole; and the arc section is elastically clamped in the ring groove. By adopting the structure, the fixing structure for the pin shaft of the grinder has the advantages that the cotter pin is simple to assemble and disassemble, the labor is saved, and the efficiency is high. The cotter pin can be recycled, and the maintenance cost is saved.
Description
Technical field
The utility model relates to the disintegrating apparatus in a kind of feed manufacturing machine field, particularly a kind of pulverizer bearing pin fixed structure.
Background technology
In the prior art, pulverizer bearing pin fixed structure comprises bearing pin, hammer frame plate, spacer, hammer leaf and split pin, hammer frame plate is equipped with at the bearing pin two ends respectively, some groups of spacers and hammer leaf are housed between the hammer frame plate, the bearing pin two ends are stretched out the outer circumference of hammer frame plate and are provided with cotter-pin hold, during installation, after pin-and-hole is passed in split pin, need with nipper plier separately opening pin, make two halves respectively around and recline the bearing pin excircle and fix, tear open when driving split pin when changing hammer leaf, need to be looped around separately section on the bearing pin respectively and flatten to merge and draw close, split pin could be taken out in pin-and-hole with nipper plier.There is following weak point in the bearing pin fixed structure of prior art: when changing hammer leaf, the dress of split pin is driven complex procedures, effort, inefficiency, and the split pin after changing can not be reused.
The utility model content
Deficiency at present technology of the present utility model provides a kind of pulverizer bearing pin fixed structure, be intended to make split pin dress drive simple, laborsaving, efficient is high, and split pin can reuse, and saves maintenance cost.
The purpose of this utility model is achieved in that a kind of pulverizer bearing pin fixed structure, comprise bearing pin, described bearing pin vertically passes a plurality of hammer frame plates that parallel, on the bearing pin between the adjacent hammer frame plate, be set with some spacers, be set with hammer leaf between the adjacent spacer on the described bearing pin, stretch out outside the hammer frame plate at the bearing pin two ends, the two ends of stretching out hammer frame plate at bearing pin are provided with radial direction through hole, it is characterized in that, be provided with cannelure with the bearing pin periphery in the same cross section of described through hole, be fitted with split pin in the through hole, described split pin comprise straight section and with the suitable segmental arc of cannelure radian, the bending transition connects between described straight section and the segmental arc, and described straight section penetrates through hole, and described segmental arc elasticity is clamped in the cannelure.
Adopt the pulverizer bearing pin fixed structure of this structure, during the construction opening pin, only need straight section with split pin penetrate the through hole of bearing pin after, the segmental arc of split pin is rotated around straight section segmental arc is clamped in the cannelure get final product by means of revolving tool again; Tearing open also only needs when driving split pin by revolving tool the extraction split pin after straight section rotates to an angle of split pin segmental arc to be got final product, and does not have distortion after the split pin dismounting of this structure, repeatedly reusable.Compared with prior art, pulverizer bearing pin fixed structure of the present utility model has the advantage that the split pin loading and unloading are simple, laborsaving, efficient is high, and split pin can be reused the saving maintenance cost.
As further improvement of the utility model, the cross sectional shape of described split pin is circular, semicircle or rectangle, with the cross sectional shape of the suitable cannelure in split pin cross section be circular arc, ellipse arc, V-arrangement or opening rectangle.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the structure chart of the utility model split pin.
Wherein, 1. split pin; 101. straight section; 102. segmental arc; 2. bearing pin; 3. hammer frame plate; 4. spacer; 5; Hammer leaf.
The specific embodiment
As Fig. 1, Fig. 2, Figure 3 shows that pulverizer bearing pin fixed structure of the present utility model, comprise bearing pin 2, bearing pin 2 vertically passes a plurality of hammer frame plates that parallel 3, on the bearing pin 2 between the adjacent hammer frame plate 3, be set with some spacers 4, be set with hammer leaf 5 between the adjacent spacer 4 on the bearing pin 2, stretch out outside the hammer frame plate 3 at bearing pin 2 two ends, the two ends of stretching out hammer frame plate 3 at bearing pin 2 are provided with radial direction through hole, be provided with cannelure with bearing pin 2 peripheries in the same cross section of through hole, be fitted with split pin 1 in the through hole, split pin 1 comprise straight section 101 and with the suitable segmental arc 102 of cannelure radian, the bending transition connects between straight section 101 and the segmental arc 102, straight section penetrates through hole, and segmental arc elasticity is clamped in the cannelure.Adopt the pulverizer bearing pin fixed structure of this structure, during construction opening pin 1, the straight section 101 of split pin 1 penetrated the through hole of bearing pin 2 after, around straight section 101 rotations segmental arc 102 is clamped in the cannelure to get final product by means of revolving the segmental arc 102 of tool again with split pin 1; Tear open when driving split pin 1 too by revolving tool the segmental arc 102 of split pin 1 is extracted out split pin 1 and get final product around straight section 101 back that rotates to an angle, do not have after split pin 1 dismounting of this structure and be out of shape, repeatedly reusable, dismounting is also fairly simple, laborsaving.The cross sectional shape of split pin is in the present embodiment selected circle for use, and the cross sectional shape of cannelure is selected semicircular arc for use.Certainly, the cross sectional shape of split pin also can be selected analogous shapes such as semicircle or rectangle for use, and the cross sectional shape of cannelure also can be selected circular arc for use, analogous shapes such as semiellipse arc, V-arrangement or opening rectangle.
The utility model is not limited to the foregoing description; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
