Description

Technical Field

[0001] The utility model relates to the technical field of ore equipment, in particular to a material distributing plate of a multi-cylinder cone crusher. Background Technique

[0002] The multi-cylinder hydraulic cone crusher is a typical crushing equipment for medium and fine crushing of hard materials. It adopts the "laminated crushing" principle to improve the primary crushing yield, with simpler and more convenient maintenance and lower operating costs. Measures such as separating the moving cone from the main shaft, thickening the main shaft and fixing it, and only the moving cone making a swinging motion are taken to improve the structural strength.

[0003] The crushing principle of the multi-cylinder hydraulic cone crusher is as follows: The working components of the multi-cylinder hydraulic cone crusher consist of two truncated cones - the moving cone and the fixed cone. During operation, the motor drives the moving cone to make a swinging motion along the inner surface through a pulley, a transmission shaft, a pinion, and a large gear. Where the moving cone is close to the fixed cone, the material is crushed by the extrusion and bending of the moving cone. Where it deviates from the moving cone, the crushed material falls from the bottom of the cone due to gravity. The entire crushing and discharging process proceeds continuously and sequentially along the inner surface. The release oil cylinder part consists of six release oil cylinders, three accumulators, and connecting pipelines. The release oil cylinder mainly plays the role of over-iron protection and cavity cleaning, and during normal crushing, it is used to absorb and buffer the impact phenomenon of the adjusting ring caused by a small number of hard materials.

[0004] The moving cone liner is installed on the moving cone, positioned by the conical surface and fixed by locking bolts. The material distributing plate is fixed above the locking bolts to protect the locking bolts. The crushed material is fed into the crusher through a feeding device and directly falls on the material distributing plate, and the material distributing plate bears the impact and wear from the material.

[0005] At present, the multi-cylinder cone locking and material distributing group of the multi-cylinder cone crusher has the following drawbacks: The weld seam between the welding ring and the welding ring is in direct contact with the ore in the crushing cavity, and it will be worn during the operation of the crusher, resulting in the loosening of the moving cone liner and causing crusher failures. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the utility model provides a material distributing plate of a multi-cylinder cone crusher, and its purpose is to set an extended protection area at the bottom of the material distributing plate to cover the locking bolts, the welding ring, and the weld seam of the welding ring for protection.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A material distributing plate of a multi-cylinder cone crusher, including a plate body, locking bolts, a welding ring, a moving cone liner, and a moving cone. The plate body is installed on the top of the locking bolts. The moving cone liner and the moving cone are sequentially arranged at the bottom of the locking bolts. A welding ring is arranged between the moving cone liner and the locking bolts. An extended protection area is arranged at the bottom of the plate body to cover the locking bolts and the welding ring.

[0008] Further, a material receiving area and a protection area are respectively arranged at the top and bottom of the disk body. The protection area is a frustum of a cone, and a hollow through hole is arranged inside the frustum of the cone. The top of the frustum of the cone is connected to the bottom of the disk body.

[0009] Further, the top diameter of the frustum of the cone is the same as the bottom diameter of the disk body.

[0010] Further, fixed through holes are arranged inside the disk body.

[0011] Further, the locking bolt and the moving cone are in threaded connection, and the locking bolt fixes the moving cone liner on the moving cone.

[0012] Compared with the existing technology, the utility model has the following beneficial effects: The utility model can protect the locking bolts installed at the bottom through the disk body. Through the extension part arranged at the bottom of the disk body, the welding ring exposed outside can be protected, avoiding the direct contact between the locking bolts, the welding ring and the weld on the welding ring and the ore in the crushing cavity, thus causing wear.
