Description

Technical Field

[0001] The present application relates to the technical field of scrap steel crusher equipment, and in particular to a scrap steel crusher rotor structure. Background Art

[0002] The effective recycling of scrap metal resources can reduce the exploitation and consumption of natural mineral resources, thereby reducing land occupation, lowering total social energy consumption, saving investment, protecting the ecological environment, and improving labor productivity.

[0003] Scrap steel crusher is a kind of crushing equipment specially used for processing scrap steel materials. It is mainly used to crush large pieces of scrap steel materials such as scrapped cars, scrapped home appliances and thin scrap steel into small pieces of scrap steel for further recycling and smelting. The working principle of scrap steel crusher is to strike, tear and grind the scrap steel through the high-speed rotation of high-manganese steel hammers, so that it rotates between narrow grid plates and finally processed into small pieces of scrap steel crushed materials. In this process, the rust, dirt and paint on the surface of the scrap steel are ground off and treated at high temperature, so that the scrap steel element content of the crushed material is as high as 98% or more, which becomes a high-quality raw material for steel mills to return to the furnace for smelting.

[0004] Among them, the rotor is the core component of the scrap steel crusher, and its structural design directly affects the crushing efficiency and service life of the scrap steel crusher.

[0005] A Chinese patent with announcement number CN217249357U discloses a crusher rotor for crushing scrap steel, comprising a main shaft, a rotor disc, a hammer, and a hammer shaft. A plurality of rotor discs are provided, and the rotor discs are fixedly arranged on the main shaft at intervals. The hammer shaft passes through each rotor disc, and the hammer shaft is connected to the rotor disc; the hammer is arranged on the hammer shaft, and there is a hammer between each two adjacent rotor discs, and the hammer comprises a hammer handle and a hammer head; the hammer shaft passes through one end of the hammer handle and is rotatably connected to the hammer handle; an adjustment groove is provided on the end face of the hammer handle away from one end of the hammer shaft, and one end of the hammer head slides in the adjustment groove; a sliding hole is provided on the side wall of the hammer handle, and the sliding hole is connected to the adjustment groove; a fixing hole is provided on the side wall of the hammer head; a fixing rod is provided in the sliding hole, and the fixing rod passes through the sliding hole and is inserted into the fixing hole; one end of the fixing rod slides in the sliding hole; a fixing component for detachably fixing the fixing rod in the sliding hole is provided in the sliding hole.

[0006] When the above-mentioned crusher rotor is crushing scrap steel, the crushed scrap steel materials are easily blocked in the rotating space between the rotor disk and the main shaft on the rotor, and due to the movable connection between the hammer head and the hammer handle, materials are also easily hidden between the hammer head and the hammer handle. If the hidden materials are not cleaned in time, the connection between the hammer head and the hammer handle will be worn, which not only affects the normal adjustment function between the hammer head and the hammer handle, but also reduces the stability of the connection between the hammer head and the hammer handle, thereby increasing the risk of using the crusher rotor. Utility Model Content

[0007] In order to reduce the possibility of the scrap steel crusher rotor being blocked by materials, the present application provides a scrap steel crusher rotor structure.

[0008] The rotor structure of a scrap steel crusher provided in this application adopts the following technical solution:

[0009] A scrap steel crusher rotor structure comprises a main shaft, a rotor disk, a hammer and a hammer shaft, wherein the rotor disks are provided with a plurality of hammer shafts which are fixedly sleeved on the main shaft at intervals, and the hammer shafts are distributed in a plurality of directions along the circumference of the rotor shaft, and each of the hammer shafts is parallel to the axial direction of the main shaft and passes through a plurality of rotor disks, and the ends of each of the hammer shafts are respectively connected and arranged between the rotor disks located at the ends of the main shaft, and one hammer is provided for each hammer shaft between two adjacent rotor disks, and the hammer is slidably sleeved on the hammer shaft, and an elastic anti-blocking plate is detachably arranged between two adjacent hammer shafts located in two adjacent rotor disks, and the plurality of anti-blocking plates and the hammer cover the main shaft together, and the hammer comprises a hammer handle and a hammer head, and the hammer shaft is slidably sleeved on the hammer shaft, and the hammer head is detachably arranged at the end of the hammer handle away from the hammer shaft, and guide surfaces which facilitate material extrusion are arranged on the opposite sides of the hammer handle and the hammer head after being connected.

[0010] By adopting the above technical solution, when the scrap steel crusher is working, the rotor drives the hammer and the anti-blocking plate to rotate at high speed. The hammer strikes and tears the scrap steel, while the anti-blocking plate effectively prevents the material from being blocked inside the rotor. At the same time, the design of several guide surfaces on the hammer helps to guide the material to the outlet, further improving the crushing efficiency, and improving the stability of the connection between the hammer head and the hammer rod in the hammer.

[0011] Optionally, the anti-blocking plate is arranged in an arc shape, and the axial direction where the arc center is located is arranged parallel to the axial direction of the main shaft.

[0012] By adopting the above technical solution, the arc-shaped setting of the anti-blocking plate enables the anti-blocking plate to better adapt to the movement trajectory of the material during the rotation of the rotor, further reducing the possibility of blockage of the rotating space.

[0013] Optionally, a support frame is provided on the side of the anti-blocking plate close to the main shaft, and an insert portion is provided on the end of the anti-blocking plate corresponding to the side of the support frame facing the anti-blocking plate, the end of the anti-blocking plate is inserted in the corresponding insert portion, and the anti-blocking plate and the support frame are plug-fitted.

[0014] By adopting the above technical solution, the plug-in cooperation between the anti-blocking plate and the support frame facilitates the installation and removal of the anti-blocking plate, thereby improving the convenience of maintenance.

[0015] Optionally, stainless steel clamps connected to the hammer shaft are hingedly provided on both sides of the support frame along the main axis direction, and the stainless steel clamps located on the opposite sides of the support frame are centrally symmetrically arranged along the center of the support frame, and each of the stainless steel clamps is abutted between the hammer handle and the rotor disk and is sleeved on the hammer shaft.

[0016] By adopting the above technical solution, the setting of the stainless steel clamp not only enhances the stability of the connection between the support frame and the hammer shaft, but also prevents the hammer rod from moving radially along the hammer shaft, thereby improving the stability of the hammer head and further improving the structural strength of the rotor.

[0017] Optionally, an adjustment plate is provided on the inner edge of one side of the support frame close to the main shaft, facing the axial direction of the main shaft and always in contact with the main shaft. The adjustment plate and the support frame are slidably fitted together, an air cavity is formed between the adjustment plate and the support frame, a plurality of ventilation holes are provided through the support frame to connect the air cavity with the outside, and an elastic member is also connected between the adjustment plate and the support frame.

[0018] By adopting the above technical scheme, the hammering of the hammer head and the impact of the scrap steel material cause the relative sliding between the adjustment plate and the support frame, so that the space of the air cavity is suddenly reduced, so that the gas in the air cavity will blow the scrap material that slides from the arc surface of the anti-blocking plate to the vent of the support frame away from the support frame, thereby further reducing the possibility of blockage of the rotating space; and through the elastic force of the elastic part, the elastic recovery characteristics of the elastic part make it possible for the adjustment plate and the support frame to slide away from each other, which helps the air cavity to inhale air through the vent until the air cavity is restored to a state of gas filling, which is conducive to repeated blowing operations.

[0019] Optionally, a limiting groove is arranged in the relative side walls on both sides of the axis of the anti-blocking plate in the support frame, and the limiting groove is arranged along the axial direction toward the main shaft. A limiting block is slidably arranged in the limiting groove along its own length direction, and the limiting block is arranged on the side wall of the adjustment plate.

[0020] By adopting the above technical solution, the sliding cooperation between the limiting slide groove and the limiting block helps to improve the stability of the adjustment plate during the sliding process.

[0021] Optionally, a filter screen is provided at the end of each vent hole away from the main shaft.

[0022] By adopting the above technical solution, the setting of the filter screen can reduce the possibility of scrap steel materials entering the air cavity, thereby reducing the possibility of the blowing operation failing due to the clogging of the vent holes of the support frame by scrap steel materials.

[0023] Optionally, a rubber pad that fits the side wall of the main shaft is provided on the side wall of the adjustment plate facing the main shaft.

[0024] By adopting the above technical solution, the setting of the rubber pad can not only transform the rigid friction between the adjustment plate and the main shaft into flexible friction, thereby reducing the possibility of wear between the adjustment plate and the main shaft due to friction, but also the setting of the rubber pad can increase the friction between the adjustment plate and the main shaft, thereby improving the stability of the adjustment plate during sliding.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the scrap steel crusher is working, the rotor drives the hammer and the anti-blocking plate to rotate at high speed. The hammer strikes and tears the scrap steel, while the anti-blocking plate effectively prevents the material from getting stuck inside the rotor. At the same time, the several guide surfaces on the hammer help guide the material to the outlet, further improving the crushing efficiency, and improving the stability of the connection between the hammer head and the hammer rod in the hammer;

[0027] 2. The arc-shaped setting of the anti-blocking plate enables the anti-blocking plate to better adapt to the movement trajectory of the material during the rotation of the rotor, further reducing the possibility of blockage in the rotating space;

[0028] 3. The plug-in fit between the anti-blocking plate and the support frame facilitates the installation and removal of the anti-blocking plate and improves the convenience of maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
