Description

Technical Field

[0001] This utility model relates to the field of pulverizers, specifically to a fixed blade structure for a pulverizer that is designed to prevent breakage. Background Technology

[0002] A crusher is an electromechanical machine widely used in mining, building materials and other industries. It achieves the purpose of crushing through high-speed impact. The crusher is mainly composed of a main shaft, rotor, hammers, screen, cover plate, door cover, motor, base, and housing. The types of crushers mainly include roller crushers, blade crushers and air jet crushers. Among them, the air-cooled blade crusher uses a high-speed rotating blade with a fan wheel. The fixed blades perform impact, shearing and grinding processes to achieve the crushing and separation effect of materials.

[0003] Application number CN212791241 U discloses a fixed blade mechanism for a crusher, including a base, a mounting base, and a fixed blade. The base has a U-shaped structure, and the mounting base is installed on the base. The fixed blade has a mounting block, and the fixed blade is mounted on the mounting base via the mounting block. The mounting base has a mounting groove, and first slide rails are provided at both ends of the bottom of the mounting groove. A mounting plate is slidably connected to the first slide rails. Rotary seats are provided at both ends of the left side of the mounting plate, and a threaded adjusting rod is rotatably connected to the rotating seat. The threaded adjusting rod is threadedly connected to the mounting base, and an adjusting wheel is provided at the outer end of the threaded adjusting rod. Several bolt holes are provided on the mounting plate, and the mounting block is positioned between the mounting groove and the mounting plate, connected to the mounting plate via bolts and bolt holes. This device's structure facilitates disassembly and replacement, meets the installation needs of different types of fixed blades, and is highly practical.

[0004] In existing technologies, the crushing effect is achieved through components such as a base, mounting base, and fixed blade. The fixed blade mechanism is mounted on the mounting base via a mounting block and works in conjunction with a threaded adjusting rod. During use, the fixed blade is prone to breakage due to repeated operation, and frequent replacement of the fixed blade affects work efficiency. Furthermore, the crusher easily generates cutting waste during operation, and the accumulation of waste waste can affect the cutting accuracy of the crusher. At the same time, it pollutes the surrounding environment and makes it inconvenient for workers to clean up after work. Utility Model Content

[0012] Furthermore, a cylindrical handle is provided on one side of the push-pull plate, and the handle passes through one side of the cleaning box and extends to the outside.

[0013] Furthermore, the telescopic rod is cylindrical and extends to the opposite side of the connecting block, and the control rod is cylindrical and adapted to be connected to one side of the telescopic rod.

[0014] Furthermore, the fixed blade has a square blade surface at the bottom and an arc-shaped blade edge at the top. An arc-shaped anti-collision component is provided on the outer side of the fixed blade. Reinforcing plates are installed on both sides of the fixed blade. The reinforcing plates are strip-shaped plates and are fixed by several sets of fixing bolts. The reinforcing plates are fitted and connected to the two sides of the fixed blade and extend to both ends of the fixed blade.

[0015] By setting an adjustment component and installing telescopic rods on both sides of the fixed base plate, the lateral distance of the internal fixed blades can be adjusted according to the actual type and size of the crusher, thus adapting to different crusher types and improving the application range of the fixed blades.
