Anti-iron hydraulic cone crusher utilizing magnetic arc gradual change

Abstract

The invention discloses an anti-iron hydraulic cone crusher utilizing magnetic arc gradual change. The cone crusher structurally comprises a hydraulic cylinder assembly, a support underframe, a liquidguiding tube, an electric control valve, a crushing tank and a sealing cover. The upper end of the hydraulic cylinder assembly is matched with the lower end of the crushing tank. When a partition plate needs crushing, a rotating magnetic ball is matched with a pulling switch to guide iron pieces into a collecting trough, so that an arc magnetic rod can generate a magnetic arc in the form of magnetic gradual change to guide the hidden iron pieces between a movable cone and a fixed cone by up guiding. The phenomenon that the iron pieces pass through the crusher is avoided, so that the movable cone and the fixed cone can break the partition plate without any hindrance, the pressure of the hydraulic cylinder assembly to the movable cone and the fixed cone never exceeds the rated value, and the hydraulic cylinder assembly is protected.

Description

technical field [0001] The invention relates to an anti-iron hydraulic cone crusher which utilizes the gradual change of the magnetic force arc, and belongs to the field of construction waste. Background technique [0002] The so-called construction crushing device is widely used in the crushing of the interior of buildings. After crushing, it can be used to recycle construction waste. The common equipment can be divided into jaw crusher, impact crusher and hydraulic cone crusher. etc. At present, the hydraulic cone crusher has become the mainstream of the market due to its rapid crushing, convenience and practicality. [0003] However, the hydraulic cone crushers on the market control the one-way extrusion and bending of the internal movable and fixed cones through the bottom hydraulic cylinder assembly during operation. For construction waste such as partition boards, the machine will still be damaged after surface cleaning, because there are often long screws and iron pa...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an anti-iron hydraulic cone crusher that utilizes the gradual change of the magnetic force arc. Control the one-way extrusion and bending of the internal movable and fixed cone. Although the construction waste processed has been preliminarily inspected and cleaned before being introduced into the crusher, construction waste such as partition boards will still damage the machine after surface cleaning. , because there are often long screw iron parts and hidden deep nails hidden in the partition wall, such iron parts are relatively hard and will form a rigid collision between the movable and fixed cones for a long time, forcing the machine to have iron phenomenon, The impact and collision produced by this phenomenon can easily lead to uneven force and hydraulic oil pressure changes on the bottom of the machine and the main shaft, resulting in frequent cracks at the oil return groove at the bottom, and the damage to the hydraulic cylinder assembly of the crusher will be greatly increased.
