Embodiment Construction

[0020] First introduce the working characteristics of the hoist. The hoist can run forward and reverse. When the power is off, a steel plate will pop up in the moderator of the hoist, so that the hoist cannot rotate forward or reverse when the power is off. The winch can hang the lifted items in mid-air like this.

[0021] When the rock hammer is working, the upper hammer falls and merges with the lower hammer, the U-row steel bars under the upper hammer coincide with the U-row steel bars above the lower hammer, and the upper latch is manually pushed to make the upper hammer and lower hammer integrated. Turn the winch forward, the wire rope goes up, the fixed iron plate on the wire rope will bring up the upper hammer and the lower hammer, cut off the power supply, and aim the lower hammer at the stone to be broken. Reverse the winch, make the lower hammer fall on the stone, disconnect the power supply, and manually pull out the latch. When the hoist is turned forward, the u...

Abstract

Ores exploited from mines are mostly broken by a big iron hammer by using man power, and the broken rock is then delivered into a crusher. The labor intensity is high, and the efficiency is low. With the ore rock breaking hammer provided by the invention, efficiency can be improved, and labor intensity can be reduced. The ore rock breaking hammer is characterized in that two big hammers are adopted. Arm lengths of the two big hammers are 2.5m. The weight of an upper hammer is 100kg, and the weight of a lower hammer is 20kg. The two big hammers are connected on a round steel bar. A lower hammer surface is small. The bottom surface of the lower hammer is placed on a rock to be broken, and the upper hammer is pulled up by using external force. With the effect of a spring, the upper hammer is quickly dropped, and beats right on the lower hammer. Because the upper hammer is heavy, and a traveling distance is long, the force is large. A common ore rock can be broken with one beat. The function of the lower hammer is collimation. The equipment provided by the invention can be used in mines, construction sites, and earth work tamping.

Description

1. Technical field [0001] Mine production tools. 2. Background technology [0002] Most of the ore mined in the mine is in large pieces, which can only enter the crusher after manual crushing. At present, hook machines and loaders are mainly used as power and hydraulic breakers are used to break ores, rocks, etc. Although the efficiency is high, the cost is very high. The vast majority of mines and concentrators have to rely on manpower to break with sledgehammers. The ore rock crushing tool of this invention has a simple structure, and even if every miner can afford it, the labor intensity of the miners can be greatly reduced and the efficiency can be improved. 3. Contents of the invention [0003] Use two sledgehammers. The arms of the two sledgehammers are each 2.5 meters long, the upper hammer weighs 100 kilograms, and the lower hammer weighs 20 kilograms. The two sledgehammers are connected on the same round steel, and the bottom surface of the lower hammer is smal...
