Description

Technical Field

[0001] The utility model relates to an intermediate base with a constant cavity distance for a crusher stone-forging iron crushing cavity, which can adjust the distance between the impact surface of the impact block in a stone crusher and the impeller surface in the crusher stone-forging iron crushing cavity, and belongs to the field of manufacturing intermediate bases dedicated to crushers. Background Art

[0002] CN114570480A, titled "Vertical Shaft Impact Crusher Sand Making Machine and Recycling Method of Counterattack Blocks", stones enter the stone-beating iron crushing chamber through the hopper assembly, and the impeller in the stone-beating iron crushing chamber rotates at high speed driven by the motor, transmission box and main shaft assembly, hitting the stones on the middle part formed by the superposition of the upper counterattack block and the lower counterattack block. Over time, when the stones grind the middle part formed by the superposition of the upper counterattack block and the lower counterattack block to form an arc groove that cannot be used, the upper counterattack block and the lower counterattack block are removed respectively, turned around and re-superposed to form the middle part of the counterattack block as new, and reuse is achieved. Advantages: After the counterattack block in the stone-beating iron crushing chamber of the vertical shaft impact crusher sand making machine is designed from an integral structure to a component structure superposition, the service life of the counterattack block is doubled, which not only reduces the manufacturing cost of sand making or crushed stone, but also greatly reduces the replacement frequency of the counterattack block, achieving unexpected technical and economic dual effects. But the problem is: in actual application, no matter the upper impact block or the lower impact block has a thickness of more than 8mm, a crusher needs more than 24 pieces of crushing wall, and the efficiency of crushing stone can be best only when the distance between the impact surface of the impact block in the crushing chamber wall of the crusher and the impeller surface in the crushing chamber of the crusher is relatively constant. When the distance between the impact surface of the impact block in the crushing chamber wall of the crusher and the impeller surface in the crushing chamber of the crusher becomes larger, it will directly lead to a decrease in the efficiency of crushing stone by the crusher, and replacement will increase the cost of stone crushing. Summary of the invention

[0003] Design purpose: To avoid the shortcomings of the background technology, a constant intermediate base for the crushing chamber of the stone crusher is designed, which can compensate the distance between the impact surface of the impact block in the stone crusher and the impeller surface in the crushing chamber of the stone crusher according to the wear amount of the impact block.

[0004] Design scheme: In order to achieve the above design objectives. The utility model has a structural design: on the basis of the existing stone crusher, an intermediate base with a thickness of Xmm or X+Ymm is provided between the impact block base and the impact block. The function of the intermediate base is: when the impact block is worn away by Xmm or X+Ymm, an intermediate base with a thickness of Xmm or X+Ymm is provided between the impact block base and the impact block, so that the distance between the impact surface of the impact block and the impeller surface in the crushing chamber of the crusher is restored to a relatively constant distance, so as to ensure that the efficiency of the crusher in crushing stones will not change.

[0005] Technical solution: An intermediate base with a constant cavity distance for a crusher for stone-breaking and iron-breaking crushing chambers, wherein one end of the intermediate base of the impact block has a T-shaped head, and the T-shaped head is clamped with a U-groove in the impact block base on the wall of the stone-breaking and iron-breaking crushing chamber; the other end of the intermediate base of the impact block has a U-groove in the middle from top to bottom, and the U-groove is used to clamp with the T-shaped head on the impact block.

[0006] Compared with the background technology, the utility model not only improves the utilization rate of the impact block, but also ensures that the stone crushing effect will not be changed, and reduces the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Embodiment 1: refer to the attached Figure 1-3 A middle base for a crusher with a constant cavity distance of a stone-beating iron crushing chamber, wherein one end of the middle base 3 of the impact block has a T-shaped head, which is clamped with a U-groove in the impact block base 2 located on the wall of the stone-beating iron crushing chamber, and the other end of the middle base 3 of the impact block has a U-groove from top to bottom in the middle, which is used to clamp with the T-shaped head on the impact block. The thickness of the middle base is equal to the thickness of the impact block wear amount 5.

[0011] Reference Figure 2 The crushing chamber 1 of the crusher has a wall of the crushing chamber as an impact block base 2, and an impact block 4 is arranged on the impact block base 2. The distance between the impact surface of the impact block 4 and the impeller surface in the crushing chamber of the crusher is constant. When the impact block 4 surface is worn away by the stone material by X=30mm, ..., an intermediate base 3 with a thickness of X=30mm is arranged between the impact block base 2 and the impact block 4, so that the distance between the impact surface of the impact block 4 and the impeller surface in the crushing chamber of the crusher is restored to a constant distance.
