Abstract

The invention relates to non-standard equipment for coal mines and coal preparation plants, and particularly relates to a large-fall vibration absorption and noise reduction buffering device. The large-fall vibration absorption and noise reduction buffering device comprises an upper sliding chute section, a middle sliding chute section and a lower sliding chute section which are sequentially connected with one another, and is characterized in that a buffering box is arranged at the upper sliding chute section; a plurality of buffering structures are arranged at the bottom of the middle sliding chute section; and a plurality of ring hammers are suspended at the tail end of the lower sliding chute section. The large-fall vibration absorption and noise reduction buffering device has the beneficial effects that the impact of the device to the device body and subsequent equipment is greatly weakened, the service life of the device and the service life of the subsequent equipment are prolonged, the maintenance for the equipment is greatly reduced, the material cost and the maintenance cost are saved, the labor intensity of workers is alleviated, the stability of a system is improved, and the working environment of the workers is also improved.

Description

(1) Technical field [0001] The invention relates to a non-standard equipment used in coal mines and coal preparation plants, in particular to a shock-absorbing and noise-reducing buffer device with a large drop. (2) Background technology [0002] Chutes are necessary non-standard parts in coal mines, and there are a large number of them. Most mechanical equipment and storage devices are connected by chutes. The chute plays a pivotal role in the process of material circulation and storage. It is an important link in coal mine production and a part with a high maintenance rate in coal mine production. For most coal mines and coal preparation plants, due to process requirements and site constraints, chutes with large drop (vertical drop exceeding 5m) inevitably appear. Due to the large impact force of the material, it will cause great impact damage to the chute and subsequent equipment, and also generate huge noise, which seriously threatens the health of coal mine wo...
