Description

Technical Field

[0001] The utility model relates to the technical field of breaker hammers, in particular to an automatic gravity drop hammer for breaking zircon corundum bricks. Background Art

[0002] Zircon corundum brick is a white solid formed by melting pure alumina powder and zircon sand containing about 65% zirconium oxide and 34% silicon dioxide in an electric melting furnace and then injecting it into a mold for cooling. Its petrographic structure consists of a eutectic of corundum and zirconolite and a glass phase. In terms of phase science, it is a eutectic of corundum phase and zirconolite phase, and the glass phase fills the gaps between their crystals. The material of zircon corundum brick is relatively expensive, and generally defective zircon corundum bricks can be crushed and recycled.

[0003] Due to the high hardness of zircon corundum bricks, during the process of gravity breaking zircon corundum bricks with some existing breaker hammers, the breaking teeth on the surface of the breaker hammer are easily worn flat and lose the breaking function, resulting in a reduction in the breaking efficiency of the breaker hammer, and the cost of replacing the breaker hammer is relatively high. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the disadvantages that during the process of gravity breaking zircon corundum bricks with some existing breaker hammers, the breaking teeth on the surface of the breaker hammer are easily worn flat and lose the breaking function, resulting in a reduction in the breaking efficiency of the breaker hammer, and the cost of replacing the breaker hammer is relatively high, and to provide an automatic gravity drop hammer for breaking zircon corundum bricks.

[0005] The purpose of the utility model is achieved through the following technical solutions: The automatic gravity drop hammer for breaking zircon corundum bricks includes a main hammer body. A breaking hammer head is installed at the bottom of the main hammer body. A plurality of groups of breaking teeth are installed on the bottom surface of the breaking hammer head. A first threaded hole is opened on one side of the breaking hammer head close to the main hammer body. A second threaded hole corresponding to the first threaded hole is opened on the main hammer body. The main hammer body is detachably connected to the breaking hammer head by a main fixing bolt threaded into the first threaded hole and the second threaded hole respectively. By setting the main fixing bolt to be threaded into the first threaded hole and the second threaded hole, the detachable connection between the main hammer body and the breaking hammer head can be realized, the breaking hammer head can be replaced after being worn for a long time during use, the breaking efficiency of the equipment can be ensured, and at the same time, only replacing the breaking hammer head can achieve the purpose of saving costs.

[0006] A further technical solution is that a plug hole is opened on one side of the main hammer body close to the breaking hammer head. A plug fixing column adapted to the plug hole is installed on the breaking hammer head. The plug fixing column is inserted into the plug hole. Setting the plug fixing column to be inserted into the plug hole can improve the bonding strength between the main hammer body and the breaking hammer head and improve the installation strength of the breaking hammer head.

[0007] A further technical solution is that a third threaded hole is provided on the plug-in fixing column, and a fourth threaded hole corresponding to the plug-in hole is provided on the main hammer body. The main hammer body is detachably connected to the plug-in fixing column through auxiliary fixing bolts respectively with the third threaded hole and the fourth threaded hole. By setting the auxiliary fixing bolts to be threadedly connected with the third threaded hole and the fourth threaded hole, the further fixing of the crushing hammer head can be achieved, and the stability of the crushing hammer head on the main hammer body can be improved.

[0008] A further technical solution is that two groups of lifting ear plates symmetrical about the main hammer body are installed on the upper part of the main hammer body. By setting the lifting ear plates, it is convenient to lift the main hammer body.

[0009] A further technical solution is that the material of the crushing hammer head is high manganese steel, and the material of the crushing teeth is high chromium cast iron block. By setting the material of the crushing hammer head to be high manganese steel and the material of the crushing teeth to be high chromium cast iron block, the wear resistance of the crushing hammer head and the crushing teeth can be improved, thereby improving the durability of the crushing hammer head and the crushing teeth.

[0010] A further technical solution is that a strengthening part corresponding to the first threaded hole is installed on the crushing hammer head. By setting the strengthening part, the strength can be improved, the first threaded hole and the main fixing bolt can be protected, and the deformation between the main fixing bolt and the first threaded hole can be avoided during the process of dropping the hammer.

[0011] A further technical solution is that multiple groups of crushing teeth are arranged in a circular array on the crushing hammer head. By setting the crushing teeth to be arranged in a circular array on the crushing hammer head, the crushing teeth can be evenly distributed on the crushing hammer head, and the crushing efficiency of the crushing hammer head can be improved.

[0012] The utility model has the following advantages: By setting the main fixing bolt to be threadedly connected with the first threaded hole and the second threaded hole, the detachable connection between the main hammer body and the crushing hammer head can be realized, and the crushing hammer head can be replaced after being worn for a long time during use, ensuring the crushing efficiency of the equipment. At the same time, only replacing the crushing hammer head can achieve the purpose of saving costs. By setting the material of the crushing hammer head to be high manganese steel and the material of the crushing teeth to be high chromium cast iron block, the wear resistance of the crushing hammer head and the crushing teeth can be improved, thereby improving the durability of the crushing hammer head and the crushing teeth. By setting the crushing teeth to be arranged in a circular array on the crushing hammer head, the crushing teeth can be evenly distributed on the crushing hammer head, and the crushing efficiency of the crushing hammer head can be improved.
