Abstract

The thumping device claimed in the present invention comprises a tamping rod, a tamping hammer, a cam drive mechanism and a guiding and limiting mechanism; the guiding and limiting mechanism comprises two fixed support plates separated on two opposite sides of the tamping rod, wherein each fixed support plate A baffle is respectively fixed on the end face facing the tamping rod, and a certain gap is left between the baffle and the tamping rod; the fixed bracket plate is rotatably connected with two swing arms upward on the side away from the tamping rod, each of which The part of the first swing arm on the fixed bracket plate leans against the end face of the fixed bracket plate, and the two swing arms are rotatably connected with stop wheels on the side away from the fixed bracket plate; The swing arms are provided in one-to-one correspondence, and elastic members are respectively connected between the two corresponding swing arms on the two fixed bracket plates, so that the roller surfaces of the two retaining wheels lean against the stamping rod. The invention has a simple structure and is convenient for the manipulation of the hammering device; at the same time, it has the function of prolonging the service life of the guiding and limiting mechanism.

Description

technical field [0001] The invention belongs to the technical field related to mechanical manufacturing, and in particular relates to a hammering device. Background technique [0002] Coke oven is a furnace made of refractory bricks and refractory blocks. When the coke oven is working, it heats the pulverized coal placed in the coke oven in a closed space to make the temperature in the coke oven reach the required level for production. required high temperature requirements. Among them, the existing pulverized coal added to the coke oven is usually in a block structure, so as to facilitate the addition of pulverized coal into the coke oven, and as much pulverized coal as possible can be added to the coke oven at one time. [0003] At present, enterprises use a hammering device to hammer the pulverized coal to compress the loose pulverized coal into a block-like structure according to the needs of use. However, the existing hammering device for hammering pulverized coal has...

Problems solved by technology

However, the existing hammering device for hammering pulverized coal has a complex structure, and when the hammering device is in contact with the pulverized coal and hammers the pulverized coal, because the overall height of the pulverized coal added is uneven, the pressure on the hammering device will be uneven. The force on both sides of the channel steel is unbalanced, so that the channel steel part of the hammering device will bend after a period of time, so that the channel steel on the crushing device will contact the baffle plate on the hammering device when it falls onto the coal powder And produce friction, wherein the structural hardness of the baffle used to guide the limit channel steel is less than that of the channel steel, thus causing the baffle to be damaged due to continuous wear and tear, so the existing hammering device needs to be constantly replaced when in use baffle
