Vertical-shaft sand making machine

Abstract

The invention discloses a vertical-shaft sand making machine which comprises a frame. A vertical-shaft box seat is arranged on the frame; a vertical shaft component driven by a motor is arranged in the vertical-shaft box seat; a crushing assembly for crushing stone is arranged above the vertical shaft component; a feed hopper is arranged above the crushing assembly; the crushing assembly comprises a crushing cavity component and a rotor component, wherein the crushing cavity component is fixed on the frame, and the rotor component is arranged in the crushing cavity component and connected with the vertical shaft component to crush stone; the feed hopper and the crushing cavity component are communicated with each other through a feed channel between the feed hopper and the crushing cavitycomponent; and a lubricating system is arranged in the vertical shaft component. According to the invention, the rotor speed is obviously increased, the crushing efficiency is high, and functions of fine crushing and shaping are realized; the stone can form a protective bottom layer to protect the machine body from abrasion; the easily damaged parts are made from special wear resistant material, and convenient to maintain and replace; due to the thin oil lubricating system, the problem of spindle locking is effectively solved; the crushing and shaping are realized by adjusting the overflow port; and the amplitude of the entire machine is small and is normally smaller than 10 mm.

Description

technical field [0001] The invention relates to mining machinery and equipment, in particular to a vertical shaft sand making machine. Background technique [0002] With the vigorous development of my country's economy, mining machinery and equipment have also developed rapidly. Many domestic enterprises have developed advanced mining equipment that meets national conditions through the introduction of foreign advanced technology and independent research and development. A manufacturing company develops a high-tech sand making machine. At present, the vertical shaft sand making machines developed by various domestic enterprises have two working principles: one is the crushing principle of "rock hitting rock"; the other is the crushing principle of "rock hitting iron". The appearance and structure of the equipment also exist in various forms, but the specific structural forms are different, resulting in different performance of the whole machine. The low speed of the rotor re...

Problems solved by technology

The appearance and structure of the equipment also exist in various forms, but the specific structural forms are different, resulting in different performance of the whole machine. The low speed of the rotor results in low crushing efficiency, imperfect fine crushing and shaping functions, and serious wear and tear on the machine body by stone materials. , In addition, due to insufficient lubrication of the vertical shaft, the vertical shaft may be locked
