Novel reaction type sand making machine

Abstract

The invention relates to a novel reaction type sand making machine. The front end surface and the rear end surface of the inner part of a machine frame are provided with lining plates, three plate hammer rotors are arranged in the centre of the machine frame, the left sides and the right sides of the three plate hammer rotors are respectively provided with reaction frames, the outer sides of the reaction frames are movably connected with reaction frame adjusting devices, and protection covers are covered at the outer sides of the reaction frames. The strength of plate hammers is improved, the utilization rate of the plate hammers is improved, a material is saved, and a resource is saved. Each plate hammer is in gapless fit with a plate hammer pedestal A, so that a clamping part formed by each plate hammer and the plate hammer pedestal is firm, sand can be quickly formed, the production volume is high, and the power consumption per cubic sand is reduced. Because of a converter system, the rotation speed of each plate hammer can be continuously improved during the attrition process, the stable reaction force of the rotors can be kept, the production efficiency is improved, the sand forming quality is improved, and the requirements on the heights of springs are reduced. The reaction frame is relatively durable, and the adjusting travel is large. The novel reaction type sand making machine has the characteristics of strong durability, novel and simple structure and convenience for operation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery and equipment, and relates to a novel impact sand making machine. Background technique [0002] With the rapid development of my country's infrastructure, especially the rapid advancement of urbanization, the demand for sand in construction projects is increasing; on the other hand, with the improvement of national and local environmental awareness; the strengthening of legislation and law enforcement, available Mining less and less river sand. As a natural resource, river sand cannot be regenerated in a short period of time. In many areas of our country, natural sand resources are rapidly decreasing, or even there is no natural sand. The contradiction between supply and demand of sand is particularly prominent, which naturally provides a market for artificial sand. . [0003] As we all know, river sand is formed by stones being scoured and collided with each other after years of ri...

Problems solved by technology

The former requires a lot of power during the sand making process, and the power consumption per cubic meter of sand is high, which does not conform to the national industrial policy of energy conservation and emission reduction. In addition, due to structural limitations, the strength and rigidity of the upper support of the vertical shaft are weak, and after a period of use , the rotor is out of balance due to wear and tear, resulting in shaking, and must be stopped for repair; the latter is due to unreasonable structure, the hammer head support has no protection device, often the hammer head support breaks, the hammer head falls off, and the machine is broken, which seriously affects the machine. The efficiency of sand making, and the sand produced has flakes and cracks, and the quality of the sand is far from that of natural sand.
