Feeding quantity digital display adjustable totally-enclosed crushing device

Abstract

The invention relates to the technical field of feeding amount adjustable crushing devices, in particular to a feeding amount digital display adjustable totally-enclosed crushing device. The feeding amount digital display adjustable totally-enclosed crushing device comprises a discharging part, the discharging part internally at least comprises a first shell, a feeding port is formed in the position, close to the top edge, of the surface of the left side of the first shell, springs are embedded in a plurality of supporting columns, a scraping plate is fixedly connected to one ends of the springs, a discharging transmission mechanism is fixedly installed on the surface of the rear side wall of the first shell, and a driven belt wheel is embedded in a fixing shaft; and an eccentric shaft is fixedly connected to the eccentric position of the surface of the side wall of the driven belt wheel, a pawl is fixedly hinged to the eccentric shaft, a ratchet wheel is fixedly connected to one end of a discharging shaft, and teeth are arranged on the periphery of the side wall of the ratchet wheel. Intermittent braking of a discharging plate is achieved through ratchet wheel transmission, while the discharging plate achieves quantitative intermittent feeding on materials, the materials can be buffered, and the situation that the materials directly impact a crushing roller, and consequently the crushing roller is damaged is prevented.

Description

technical field [0001] The invention relates to the technical field of a crushing device with adjustable feeding amount, in particular to a fully enclosed crushing device with a digital display adjustable feeding amount. Background technique [0002] Crusher is a kind of equipment for crushing stones of different sizes. With the development of science and technology, there are more and more types of crushers. Crusher has been used in cement, building materials, coal and chemical industry and mineral processing in my country. It is widely used in the fine crushing and coarse crushing of various ores in the industrial sector. It has a large crushing ratio for crushing shale, coal, coal gangue, cinder, gypsum, salt mine emery and various brittle minerals below medium hardness. , small and uniform particle size, high output and long life. In the chemical industry and electric power sector, crushing and grinding machinery crushes and grinds raw materials, increases the surface area...

AI Technical Summary

Problems solved by technology

[0003] When crushing materials, in order to measure the total amount of crushed materials and count the crushing efficiency, a quantitative feeding mechanism is added in front of the crushing device, and the data such as the amount of feed is displayed on the display to assist in crushing. However, there are The conveyor belt of the quantitative feeding mechanism is prone to material residue during the conveying process, which will affect the measurement of the new material delivered by the load-bearing sensor, and then cause the measurement error of the feed amount, which seriously affects the accuracy of the measurement display. At the same time, the input The delivered material is sent into the crushing cavity, which directly impacts the crushing roller, which is extremely tolerant to damage the crushing roller. Therefore, the purpose of the present invention is a fully enclosed crushing device with digital display and adjustable feeding to solve the problem of feeding The material is sent into the crushing cavity, which directly impacts the crushing roller, which is extremely easy to cause damage to the crushing roller.
