Description

Technical Field

[0001] This utility model relates to the field of compression device technology, and in particular to a raw material compression device for a crusher. Background Technology

[0002] The raw material compression device for crushers is an important component used in crushing equipment. It is mainly used to compress the raw materials entering the crusher. Scrap metal usually needs to be crushed by a crusher before recycling and smelting. The crusher breaks large pieces of scrap metal into smaller particles or fragments, which greatly increases the contact area between the metal and the heat and chemical reagents in the smelting furnace.

[0003] In existing technologies, after compressing raw materials, it is easy to discharge the compressed raw materials and reload them. The rapid reloading function allows the crusher to quickly enter the next raw material processing cycle after completing one compression operation, without the need for long intervals and preparations. This helps to achieve the continuity of the production process and maintain a stable production rhythm, which is crucial for large-scale, high-efficiency production operations. It can process more raw materials per unit time and increase output.

[0004] However, in practical applications, parts that come into direct contact with the raw materials, such as the pressure head and the walls of the compression chamber, are prone to wear due to long-term friction, impact, and compression from the raw materials. This wear leads to uneven distribution of the compression force in the compression device, resulting in inconsistent pressure on the scrap metal during compression. This causes the compressed metal blocks to have uneven density and irregular shape, affecting their quality. Such unevenly sized metal blocks may become loose or break during subsequent transportation, storage, and reprocessing, reducing the overall quality of the product.

[0005] Therefore, this application provides a raw material compression device for a crusher to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and propose a raw material compression device for crushers.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a raw material compression device for a crusher, comprising:

[0008] compressor;

[0009] A compression assembly is placed inside a compressor. The compression assembly includes a pressure head that rotates inside the compressor. A protective plate is provided at the bottom of the pressure head. A snap-fit ​​plate is fixedly connected to the side of the protective plate near the pressure head. The protective plate is snapped to the pressure head through the snap-fit ​​plate.

[0010] The fixing assembly is arranged inside the compression assembly and is used for fixing the protective plate at the bottom of the pressing head, and the fixing assembly comprises a rotating shaft movably arranged inside the pressing head, a connecting plate arranged on one side of the rotating shaft close to the protective plate, rotating plates rotatably connected on both sides of the connecting plate, and a clamping block one rotatably connected on one side of the rotating plate close to the clamping plate.

[0011] Further, one side of the protective plate close to the connecting plate is fixedly connected with a supporting seat.

[0012] The beneficial effect of the above further scheme is that the supporting seat can limit the movement of the connecting plate and support the connecting plate from the bottom.

[0013] Further, one end of the rotating shaft away from the connecting plate is fixedly connected with a clamping block two, one side of the pressing head close to the clamping block two is provided with a clamping groove, the clamping block two is slidably connected with the clamping groove, and the rotating shaft is clamped with the pressing head through the clamping block two and the clamping groove.

[0014] The beneficial effect of the above further scheme is that the stability of the compression assembly during use can be improved, the rotating shaft is rotated, and the clamping groove is rotated in the clamping block two.

[0015] The beneficial effect of the above further scheme is that the rotating shaft can slide in the pressing head to drive the connecting plate to move.

[0016] Further, one side of the clamping block one close to the supporting seat is fixedly connected with a limiting block, one side of the supporting seat close to the limiting block is provided with a limiting groove, and the clamping block one is slidably connected with the supporting seat through the limiting groove and the limiting block.

[0017] The beneficial effect of the above further scheme is that the limiting block cooperates with the clamping block two to limit the movement line of the clamping block one, so as to avoid the deviation of the clamping block one during movement.

[0018] Further, one end of the rotating shaft close to the connecting plate is fixedly connected with a sliding block, and the rotating shaft is rotatably connected with the connecting plate through the sliding block.

[0019] The beneficial effect of the above further scheme is that the rotating shaft drives the connecting plate to move through the sliding block, and the rotating shaft remains stable during vertical movement.

[0020] Further, one end of the rotating shaft close to the top of the pressing head is fixedly connected with a fixing piece, and the rotating shaft is fixedly connected with the pressing head through the fixing piece.

[0021] The beneficial effect of the further scheme is that the problem of loosening between the pressing head and the protective plate caused by accidental rotation of the rotating shaft is avoided, and the stability of the compression assembly and the fixing assembly in use is improved.

[0022] Further, the clamping groove is provided with an anti-rust coating.

[0023] The beneficial effect of the further scheme is that the service life of the clamping groove is prolonged, and the problem of the protective plate being unable to be replaced caused by rust in the clamping block two is avoided.

[0024] Compared with the prior art, the advantages and positive effects of the utility model are that:

[0025] 1. The compression assembly is arranged, the protective plate can play a blocking role, and direct contact of the raw material with the pressing head is prevented, thereby playing a protection effect on the pressing head. Since the protective plate is divided into multiple parts, when the protective plate is worn, the corresponding protective plate can be replaced according to the actual wear position and wear degree, so that the cost of replacing the protective plate is reduced. Meanwhile, the clamping plate and the clamping block one are arranged on each protective plate, and when the protective plate is pushed into the pressing head, the fixing column is clamped with the groove on the pressing head, so that the protective plate is preliminarily fixed, the protective plate is convenient to separate from the pressing head, and the efficiency of replacing the protective plate is improved.

[0026] 2. The fixing assembly is arranged, when the rotating shaft is pushed downward on the pressing head, since the clamping block one is connected with the connecting plate and the rotating plate through the rotating shaft arranged on the clamping block one, when the connecting plate moves together with the rotating shaft, the rotating plate pushes the clamping block one to move towards the inner side of the clamping plate until the clamping block one is clamped with the clamping plate. In this way, the pressing head and the protective plate are fixed, the stability of the protective plate in use is improved, and the structure design provides a convenient condition for replacing the protective plate.
