The eccentric shaft can drive the movable jaw plate to move in the rotating process, so that the upper part of the movable jaw plate presses the fixed jaw plate. To the unsmooth, or the concrete piece that has more edges and corners of appearance, the easy emergence is broken up when the extrusion to form a plurality of less concrete pieces, and crushed aggregates passageway's width top-down reduces gradually, and less concrete piece can fall the lower part in crushed aggregates passageway and is extrudeed once more, can not leave crushed aggregates passageway until the concrete piece is crushed can pass through crushed aggregates passageway the size of below. In the case of a concrete block having a flat shape, for example, a concrete block from a wall, since the contact area between the concrete block and the jaw plate is large during extrusion, the pressure applied during extrusion is small, and the concrete block is relatively less likely to be crushed. In addition, when the thickness of the extruded concrete block is smaller than the distance between the lower end of the fixed jaw plate and the movable jaw plate, the concrete block can leave the crushed material channel, so that the crushed concrete block is easy to have larger flat and long crushed blocks. And the jump bit in this scheme can transversely strike the concrete piece, and when the concrete piece in the crushed aggregates passageway was the platykurtic, the jump bit can strike two great sides of concrete piece, made the concrete piece take place to collapse the bits of broken glass more easily to have great platykurtic fragment in avoiding the concrete piece of collecting as far as possible, the shape after making the crushed aggregates is more even, has improved the effect of crushed aggregates.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

In the embodiment shown in fig. 1, the multi-directional material crushing machine comprises a fixed jaw 1 and a movable jaw 2, wherein the movable jaw is connected to an eccentric shaft 3, the upper part of the movable jaw has a large horizontal movement amount and the lower part of the movable jaw has a small horizontal movement amount during movement, the eccentric shaft is driven by a belt pulley 4 to rotate to form a material crushing channel 5 between the fixed jaw and the movable jaw, the material crushing channel is gradually reduced from top to bottom, and an impact opening 6 facing the material crushing channel is formed in the fixed jaw. And an impact hammer 7 is arranged in the impact port, a conical sharp angle is arranged at the end part of the impact hammer, and the impact hammer is controlled to move by a cylinder 8. The side face, facing the fixed jaw plate, of the movable jaw plate is provided with crushing teeth used for improving shearing force during crushing, the crushing teeth comprise transverse crushing teeth 9 and vertical crushing teeth 10, the transverse crushing teeth and the vertical crushing teeth are arranged on the movable jaw plate at intervals from top to bottom, and the crushing teeth are made of high manganese steel. A blanking channel 11 is arranged below the crushed material channel, an included angle between the direction of the blanking channel and the side face, facing the crushed material channel, of the fixed jaw is 120 degrees, and the blanking channel is formed by the lower portion of the fixed jaw and the lower portion of the movable jaw. And a feeding port 12 is arranged above the fixed jaw plate and the movable jaw plate, and a brush 13 is arranged in the feeding port.

When the device is used, the concrete blocks enter the crushed material channel from the feeding port, and the brush can be squeezed open by the concrete blocks when the concrete blocks pass through the feeding port; when the eccentric shaft rotates, the upper part of the movable jaw plate continuously presses the fixed jaw plate, so that the large concrete blocks are pressed into small blocks. When the concrete block is flat or flat concrete fragments are generated in the extrusion process, the concrete block is difficult to crush due to the large contact area between the concrete block and the jaw plate and can pass through the crushing channel more easily than the spherical concrete fragments with the same volume, and the impact hammer can impact the flat concrete block, so that the larger side surface of the flat concrete block is subjected to larger pressure, and the concrete block is crushed. Meanwhile, as the movable jaw plate is provided with the crushing teeth in different directions, the shearing force to the concrete block can be improved from different angles, and the crushing effect is further improved. Because the end part of the impact hammer is conical, the pressure generated during impact is larger, and when the impact hammer impacts irregular concrete fragments, the irregular concrete fragments are easily squeezed apart, so that the impact hammer is prevented from being greatly abraded by sharp corners on the concrete blocks. When the concrete cullet falls to the bottom of crushed aggregates passageway, because the angle between crushed aggregates passageway and the unloading passageway, highly higher concrete cullet can not directly leave the crushed aggregates passageway, but stops in crushed aggregates passageway and unloading passageway's junction and constantly receives the impact of jump bit, and after the crushed aggregates once more and lead to highly reducing, could get into the unloading passageway completely to the concrete cullet that obtains after having guaranteed the crushed aggregates all is less in the ascending size of all directions. When the crushed aggregates are broken, the concrete blocks with small volume are collapsed to the feeding port, the brush can play a role in blocking, and operators around the brush are prevented from being hit.
