A material loosening machine

Abstract

The invention discloses a material loosening machine. The machine comprises a rack and a lifting power output mechanism, wherein the rack stretches across a carriage and rails to operate, the lifting power output mechanism is arranged at the top of the rack, the mechanism comprises two output ends which are distributed oppositely, each output end is provided with a chain wheel, and each chain wheel is sleeved with a chain matched with the corresponding chain wheel; a loosening rack is connected between the two chains, multiple auger drill bits used for loosening materials in the carriage are arranged on the loosening rack, each auger drill bit is driven by an independent speed-reduction motor separately, and the rotation directions of every two adjacent auger drill bits are opposite. According to the material loosening machine, the loosening rack is lifted through a transmission mechanism composed of the chain wheels and the chains, the machine is simple and reliable in structure, low in production cost, high in transmission efficiency and capable of achieving automatic feeding, and the drilling force degree of the auger drill bits is increased. The rotation directions of every two adjacent auger drill bits on the loosening rack are opposite, the materials can be stirred better, block hardened materials can be subjected to grinding in opposite directions and cutting, and the material loosening effect is substantially improved.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a material loosening machine. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used, especially in industrial and mining enterprises. [0003] At present, when using trains to transport bulk materials containing a certain amount of moisture for a long distance, due to the long-distance transportation bumps, the materials in the carriages will be hardened. Especially in winter in the north, when transporting bulk materials with a certain amount of moisture for a long distance, not only will the materials be hardened but also frozen, which will make the materials in the compartment unable to be unloaded. In view of this, in the prior art, there is a kind of equipment specially used for loosening hardened or frozen materials in the compartment—a loosening machine. [0004] The lo...

Problems solved by technology

Due to its lifting principle, the force of the hoisting mechanism during the descent process can only be provided by its gravity, so the maximum feeding force of the rotating loosening head can only be provided by the gravity of the loosening frame, which will cause insufficient feeding force of the drill bit, loosening The efficiency is low, and at the same time, the hoisting mechanism often has the phenomenon of wire rope disorder

The hydraulic cylinder mechanism needs to add a hydraulic system for lifting, and its production cost will increase significantly. At the same time, the maintenance cost of the hydraulic system in the later period is also higher than the cost of the general mechanical transmission mechanism.

The rack and pinion mechanism transmission requires high manufacturing precision and installation precision, so its cost will be relatively high
