In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:

fig. 1 is a schematic structural diagram of a crusher hammer head provided in the present invention;

fig. 2 is a front view of the crusher head shown in fig. 1;

fig. 3 is a side view of the crusher head shown in fig. 1.

[ detailed description ] embodiments

In order to make those skilled in the art better understand the technical solution of the embodiments of the present invention and make the above objects, features and advantages of the present invention more obvious and understandable, the following description will make further description of the embodiments of the present invention.

Referring to fig. 1 to 3, the present invention provides a crusher hammer head 100, which includes a shaft seat 10, a connecting portion 20 and a hammer body 30, wherein the connecting portion 20 connects the shaft seat 10 and the hammer body 30.

The shaft seat 10 is of a hollow cylindrical structure with equal wall thickness, a shaft hole 11 penetrates through the shaft seat 10, the shaft hole 11 is located at the center of the shaft seat 10, and the shaft seat 10 is sleeved on the mounting shaft through the shaft hole 11. The ratio of the diameter of the shaft hole 11 to the diameter of the shaft seat 10 is 17:33, so that the shaft seat 10 has good thickness along the radial direction, and the overall weight of the shaft seat 10 is controlled. The shearing force of resistance installation axle that great thickness can be fine avoids 11 positions in shaft hole fracture appears, has controlled weight and can reduction in production cost.

The top of the connecting part 20 is recessed to form a groove, the shaft seat 10 is located in the groove, and the connecting part 20 is welded and fixed with the circumferential surface of the shaft seat 10.

The width of the shaft seat 10 along the axis direction is greater than that of the connecting part 20, the left end and the right end of the shaft seat 10 protrude out of the connecting part 20, and the width of the left end and the right end of the shaft seat 10 protruding out of the connecting part 20 is the same. Since the connection part 20 is a non-working region, the material usage can be reduced by reducing the width of the connection part 20, thereby reducing the production cost. Meanwhile, the shaft seat 10 is selected to be larger in width, so that the contact area between the shaft seat 10 and the mounting shaft can be increased, the shearing resistance of the shaft seat 10 is further improved, and the service life is prolonged.

Further, since the hammer body 30 has a larger cross-sectional area, the cross-sectional area of the connecting portion 20 increases uniformly from the shaft seat 10 to the hammer body 30, and a right-angle transition region is formed between the connecting portion 20 and the hammer body 30 to reduce the shearing force.

The hammer body 30 comprises a transition section 31 and a working section 32, the transition section 31 connects the connecting part 20 and the working section 32, the width of the top end of the transition section 31 is the same as that of the connecting part 20, the width of the bottom end of the transition section 31 is the same as that of the working section 32, and the width of the transition section 31 increases uniformly from the top end to the bottom end. The transition section 31 also serves as a transition, and a right-angle transition region between the connecting portion and the hammer body 30 is avoided, so that the shearing force is reduced.

The working section 32 comprises a top surface 321, a bottom surface 322 opposite to the top surface 321, and a working side surface 323 connecting the top surface 321 and the bottom surface 322 and parallel to the central axis of the shaft seat 10. The number of the working side surfaces 323 is two, and the two working side surfaces 323 are symmetrically arranged at two ends of the working section 32. The hammer head rotates, only one working side 323 participates in impact crushing of materials in the rotating process, and the other working side 323 is in an idle state, so that when the working side 323 at one end of the working section 32 is greatly abraded, the whole hammer head can be reversed, the working side 323 without abrasion can be replaced to the working side, and the service life of the hammer head can be prolonged.

The side surface included angle of the working side 323 and the transition section 31 is an obtuse angle, the range of the obtuse angle is 150-170 degrees, the bottom surface 322 is an arc surface, so that the section of the working section 32 is of a fan-shaped structure and has a large sectional area, the whole volume of the working section 32 is increased, meanwhile, the two ends of the working section 32 correspondingly protrude out of the side surface of the transition section 31, the capturing capacity of the working section 32 for materials can be increased, and the part of the working section 32 protruding out of the transition section 31 can also serve as abrasion loss, so that the abrasion period of a hammer head is prolonged.

The embodiments of the present invention have been described in detail, but the present invention is not limited to the described embodiments. Various changes, modifications, substitutions and alterations to these embodiments will occur to those skilled in the art without departing from the spirit and scope of the present invention.
