Abstract

The utility model relates to a PCM-80 flour mill saddle type tup, including the grinding tup body, be equipped with the recess on the upper portion of grinding tup body, it has two screw holes to open on the grinding tup body in the recess, its characterized in that, the recess upper portion of grinding tup body be trapezoidal recess, the lower part is the rectangle recess, makes the upper portion working surface shape of grinding tup become the hammer angle, is equipped with the blind plate in the bottom of rectangle recess. The utility model has the advantages that: because the hammer angle is formed on the upper working surface of the grinding hammer head of the utility model, the working area is increased, and the service life is prolonged; the blind plate reduces the abrasion of the bolt, so that the grinding hammer head works safely and stably.

Description

PCM-80 pulverizer saddle-type hammer

Technical Field

The utility model belongs to the technical field of crushing equipment, concretely relates to PCM-80 flour mill saddle type tup.

Background

The crusher hammer is one of the core parts of the pulverizer and is arranged on a hammer shaft of a pulverizer rotor, and the hammer directly strikes materials when the pulverizer runs at a high speed, so that the materials are finally ground into proper material granularity.

At present, the shape of a grinding hammer head of a well-known PCM type vertical grinding machine is a cuboid part made of high-wear-resistance materials, a groove is formed in the upper surface of the grinding hammer head, and two mounting threaded holes are uniformly distributed in the groove. During installation, two threaded holes of the grinding hammer head are abutted to threaded holes of a rotor back plate of the grinding machine by two high-strength bolts. When the equipment is operated, the rotor drives the grinding hammer head to rotate at a high speed, when materials enter the case, because the working face of the grinding hammer head is a plane and is in direct contact grinding with the materials, the abrasion of the grinding hammer head is fast, particularly, the service life of the grinding hammer head is directly influenced by two threaded holes of the grinding hammer head and the positions of hammer angles outside the hammer head and the materials, the abrasion of the hammer angles is too large to reduce the yield, the abrasion of the threaded holes is too large to cause the falling of the hammer head to cause accidents, and once the abrasion of the two parts is out of limit, the grinding hammer head must be replaced. Frequent replacement of the grinding hammer head not only affects the efficiency of the equipment, but also increases the operation cost and the labor intensity of workers.

Disclosure of Invention

The utility model aims at providing a PCM-80 flour mill saddle type tup, this tup is stand wear and tear, and is safe firm.

The utility model aims at realizing through the following technical scheme:

the utility model discloses a PCM-80 flour mill saddle type tup, including the grinding tup body, be equipped with the recess on the upper portion of grinding tup body, it has two screw holes to open on the grinding tup body in the recess, its characterized in that, the recess upper portion of grinding tup body be trapezoidal recess, the lower part is the rectangle recess, makes the upper portion working surface shape of grinding tup become the hammer angle, is equipped with the blind plate in the bottom of rectangle recess.

The utility model has the advantages that:

because the upper working surface of the grinding hammer forms a hammer angle, the thickness of the hammer is increased, the working area is increased, and the service life is prolonged; the blind plate reduces the abrasion of the bolt, so that the grinding hammer head works safely and stably.

Detailed Description

The present invention will be described with reference to the accompanying drawings.

As shown in fig. 1-2, the saddle-type hammerhead of PCM-80 pulverizer of the present invention comprises a pulverizing hammerhead body 1, wherein a groove is formed on the upper portion of the pulverizing hammerhead body 1, and two threaded holes 3 are formed on the pulverizing hammerhead body 1 in the groove, which is characterized in that the upper portion of the groove of the pulverizing hammerhead body is a trapezoidal groove 22, and the lower portion thereof is a rectangular groove 21, so that the upper working surface of the pulverizing hammerhead forms a hammer angle, and the structure increases the contact area between the pulverizing hammerhead and the material and prolongs the service life of the pulverizing hammerhead;

the bottom of the rectangular groove is provided with a blind plate 4, and the blind plate prevents materials from wearing bolts in the threaded holes 3.

The mounting method comprises the steps of connecting the grinding hammer head body 1 to a rotor through a bolt, and clamping the blind plate 4 at the bottom of the rectangular groove.

Claims

1. The saddle-shaped hammer head of the PCM-80 pulverizer comprises a grinding hammer head body, wherein a groove is formed in the upper portion of the grinding hammer head body, and two threaded holes are formed in the grinding hammer head body in the groove.
