Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides a two-sided quartering hammer for vertical scroll breaker, including host computer rotor 1 and a plurality of quartering hammer body 2, host computer rotor 1's center is provided with main shaft 101, a plurality of quartering hammer body 2 all with host computer rotor 1's edge mounting, quartering hammer body 2 includes tup 201 and installation piece 202, recess 2011 has all been seted up to the both sides of tup 201 outer wall, two recesses 2011 are mirror symmetry and distribute, the shape of recess 2011 is "U" shape, mounting hole 2021 has been seted up to the outer wall of installation piece 202, mounting hole 2021 passes through the removable pin with host computer rotor 1 and can dismantle the connection, the length of tup 201 is three fourths of quartering hammer body 2 length, distance between two recesses 2011 is an, the degree of depth of recess 2011 is b, the length of an is greater than the length of b.

In this embodiment: the double-sided U-shaped breaking hammer is mainly suitable for materials for sand making below 7cm, the double-sided U-shaped breaking hammer rotates at a high speed in the using process, a part of materials entering a breaker are beaten and broken by using corners of U-shaped grooves 2011, at the moment, the part of the materials located in the U-shaped grooves 2011 and the newly entered materials are subjected to head-on impact friction, then the part of the materials are thrown out through centrifugal force, then the newly entered materials are circularly filled in the U-shaped grooves 2011, the materials thrown out from the grooves 2011 impact the inner wall of the breaker, the materials rebound after impact breaking, the rebounded broken materials and the thrown materials are subjected to high-speed collision and friction in the air, so closed-loop multi-cycle collision and friction between the materials are formed, the main principle is that the impact friction between the materials and sand making is carried out, the sand making efficiency is improved to 95 percent, and the finished sand is closer to natural sand, thereby improving the quality of the finished sand.

Example 2.

Referring to fig. 4-5, the present invention provides the following technical solutions: the utility model provides a two-sided quartering hammer for vertical scroll breaker, including host computer rotor 1 and a plurality of quartering hammer body 2, host computer rotor 1's center is provided with main shaft 101, a plurality of quartering hammer body 2 all with host computer rotor 1's edge-mounting, quartering hammer body 2 includes tup 201 and installation piece 202, recess 2011 has all been seted up to the both sides of tup 201 outer wall, two recesses 2011 are the mirror symmetry and distribute, the shape of recess 2011 is "V" shape, mounting hole 2021 has been seted up to the outer wall of installation piece 202, mounting hole 2021 passes through the removable pin and can dismantle the connection with host computer rotor 1, the length of tup 201 is three quarters of quartering hammer body 2 length, tup 201 and installation piece 202 casting as an organic whole, the material of quartering hammer body 2 is high manganese steel, distance between two recesses 2011 is an, the degree of depth of recess is b, a's length is greater than b.

In this embodiment: the double-sided V-shaped breaking hammer is mainly suitable for breaking aggregates and large materials, the double-sided V-shaped breaking hammer rotates at a high speed in the using process, part of the aggregates entering a breaker collides with a V-shaped axe angle of the V-shaped hammer, the axe angle can cut off the large aggregates, part of the aggregates are collected into a V-shaped groove 2011 and collide with the aggregates which are not collected into the V-shaped groove 2011, the aggregates are thrown out of the inner wall of the breaker through centrifugal force after being broken to be broken for secondary breaking, then the aggregates rebound in an inner cavity of equipment, the rebounded aggregates collide with the aggregates thrown out of the V-shaped groove 2011 for multiple times, impact and friction are carried out between the aggregates in the process, and finally the manufactured finished product materials are almost the same as natural materials.

The working principle and the using process of the invention are as follows: the friction between materials and the breaking hammer is reduced in the use process of the double-sided U-shaped breaking hammer and the double-sided V-shaped breaking hammer, the abrasion of the breaking hammer is reduced to the minimum, even if the double-sided U-shaped breaking hammer and the double-sided V-shaped breaking hammer are abraded, in the abrasion process, corners of a groove 2011 on one side of the U-shaped hammer and a groove 2011 on one side of the V-shaped hammer are abraded to be flat, the hammer 201 is abraded to be square firstly, and then is abraded to be round instead of being abraded to be round at the beginning, after the hammer 201 is abraded to be square, the hammer 201 can be continuously utilized to impact the materials, the hammer 201 cannot be used after being abraded to be round, and due to the fact that a forward and reverse rotation motor is installed at the end of the main shaft 101, the rotation direction of the main rotor 1 is adjusted at the moment, and then the groove 2011 on the other side of the breaking hammer is used, and therefore the service life of the breaking hammer is prolonged.
