Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crushing equipment, and particularly relates to a heavy-duty impact crusher structure. BACKGROUND

[0002] The impact crusher is a common crushing equipment, which mainly realizes the crushing of materials through the high-speed impact of a rotor and the repeated impact of the materials. In the specific crushing process, the rotor rotates at high speed, and the materials enter the impact crusher and are first crushed by colliding with the hammer heads on the rotor, and then are thrown to the impact plate in the crushing chamber to be crushed again, so as to be circulated until the materials are discharged from the discharge port to realize the crushing of the materials.

[0003] In the related art, the hammer heads are mainly fixed through screws, and the impact force is large when the hammer heads strike large materials in the material crushing process, so the hammer heads are prone to breakage or falling off, and the failure rate of the impact crusher is high, which is not conducive to the stable operation of the equipment. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the stability of the impact crusher in the operation process, the present application provides a heavy-duty impact crusher structure.

[0005] The heavy-duty impact crusher structure provided by the present application adopts the following technical scheme:

[0006] The heavy-duty impact crusher structure comprises a shell and a rotor assembly rotatably connected in the shell, and further comprises an impact assembly installed in the shell. The rotor assembly comprises a rotating frame, a plate hammer and a wedge. The rotating frame is rotatably connected to the shell. An installation slot is formed in the rotating frame along the direction of the rotation axis of the rotating frame. The plate hammer is inserted into the installation slot. The wedge is located in the installation slot and abuts against the plate hammer. A driving slope is arranged on the wedge. The driving slope abuts against the side wall of the installation slot. The driving slope is inclined in the direction parallel to the rotation axis of the rotating frame towards the plate hammer or away from the plate hammer. Sliding the wedge along the axis of the rotating frame can make the wedge close to the plate hammer.

[0007] By adopting the above technical scheme, the rotor assembly is arranged in the shell, and the material is crushed by the rotating rotor assembly, so as to realize the crushing function of the material. The plate hammer is inserted into the installation slot and is tightly fixed by the wedge. Compared with the screw, the overall structural strength of the wedge is higher, so the stability is higher. Moreover, in the process of crushing the material by the rotor assembly, the plate hammer is subjected to small axial force, and the influence of the axial force on the movement of the wedge is small, so that the fixing of the wedge to the plate hammer is more stable.

[0008] Optionally, a fixing member is arranged on the wedge along the direction perpendicular to the rotation axis of the rotating frame. One end of the fixing member is inserted into the rotating frame.

[0009] Through the above technical scheme, the fixing member is inserted on the rotating frame after penetrating through the wedge block, thereby limiting the displacement of the wedge block in the direction parallel to the rotating axis of the rotating frame, and improving the stability of the fixing of the plate hammer.

[0010] Optionally, the wedge block and the rotating frame are provided with fixing ears, the fixing ears are provided with through holes, the through holes of the two fixing ears correspond to each other, and the fixing member penetrates through the through holes.

[0011] Through the above technical scheme, the fixing ear is arranged, and the installation of the fixing member is facilitated.

[0012] Optionally, the fixing member is a screw, and the screw is locked by a nut after penetrating through the two fixing ears.

[0013] Through the above technical scheme, the position of the fixing member is limited after being locked by the nut, and the stability of the limiting of the wedge block by the fixing member is improved.

[0014] Optionally, the installation groove is provided with an installation surface, and the side wall of the wedge block close to the rotating axis of the rotating frame is attached to the installation surface.

[0015] Through the above technical scheme, the installation surface matched with the wedge block is arranged, so as to facilitate the installation of the wedge block and improve the stability of the wedge block after installation.

[0016] Optionally, the structures on both sides of the plate hammer are symmetrical.

[0017] Through the above technical scheme, the structures on both sides of the plate hammer are symmetrical, the plate hammer is inserted into the installation groove on one side during the crushing process, and the other side extends to the outside of the installation groove for crushing materials, when one side is seriously worn, the direction of the plate hammer can be exchanged, and the maintenance cost of the crusher is reduced.

[0018] Optionally, the rotating frame is composed of a rotating shaft and a plurality of wheel discs arranged on the rotating shaft, the installation groove is arranged on the wheel disc, and the wedge block is provided with a plurality of corresponding wheel discs.

[0019] Through the above technical scheme, the plate hammer is installed in the installation groove on the plurality of wheel discs, and the installation of the plate hammer is realized. The plurality of wedge blocks tightly abut against different positions of the plate hammer, and the stability of the fixing of the plate hammer is improved.

[0020] Optionally, the fixing ears are arranged corresponding to the wheel discs, and two groups of fixing ears are arranged corresponding to each wheel disc, and the two groups of fixing ears are arranged on the two sides of the wheel disc.

[0021] Through the above technical scheme, the arrangement of the two groups of fixing ears improves the stability of the limiting of the wedge block by the fixing member.

[0022] Optionally, an extension block is provided on the side of the mounting groove away from the wedge, and a limiting groove is provided on the hammer corresponding to the extension block. One side of the extension block is inserted into the limiting groove to prevent the hammer from moving radially along the rotation axis.

[0023] By adopting the above technical solution, under the action of the wedge, the wedge presses against the hammer plate, and the friction force is used to limit the hammer plate. The extension block is inserted into the limiting groove to limit the hammer plate again, thereby improving the stability of the hammer plate after installation.

[0024] Optionally, a stop block is provided on the extension block on the disc near the end of the rotating shaft. The stop block is slidably connected to the extension block in a direction perpendicular to the rotation axis of the rotating shaft. A corresponding groove is provided at the end of the hammer. Sliding the stop block allows one side of the stop block to be inserted into the groove.

[0025] By adopting the above technical solution, the stop block is inserted into the stop groove to limit the displacement of the hammer in the direction parallel to the axis of rotation, thereby further improving the stability of the hammer after installation. Attached Figure Description
