Three-axis linkage self-feeding mining stemming machine

Abstract

The invention discloses a three-axis linkage self-feeding mining stemming machine. The stemming machine is characterized in that a transmission unit is arranged, namely transmission shafts are horizontally arranged in a gear box in parallel and are respectively the first transmission shaft, the second transmission shaft and the third transmission shaft, and the transmission shafts are distributed in the plane perpendicular to the axis in an inverted triangle mode and axially stretch into a first output shaft, a second output shaft and a third output shaft respectively on the same output end side of the gear box; a stemming extrusion channel is formed by a stemming extrusion barrel and the first output shaft with a spiral blade; the second output shaft and the third output shaft are used for breaking and stirring stemming in a discharge hopper through a pawl on the second output shaft and a pawl on the third output shaft and provide feeding power for stemming to smoothly enter the stemming extrusion barrel, wherein the second output shaft and the third output shaft oppositely rotate. The plugging phenomenon is eliminated, and continuous production of stemming in a field can be achieved.

Description

technical field [0001] The invention relates to a three-axis linkage self-feeding mine blasting machine. Background technique [0002] Drilling and blasting are often required in engineering industries such as mining, road construction, and tunnel construction, and a large amount of blasthole mud is required to block blastholes. From the theoretical analysis of blasthole plugging, the rock-breaking energy of explosions is mainly divided into two parts, namely shock wave energy and gas expansion energy. . Shock wave energy accounts for 43.7%, and gas expansion energy accounts for 56.3%. Blasts that do not block blastholes will have 50% of the gas energy dissipated from the orifice. Therefore, the purpose of mud plugging is to give full play to the rock-breaking effect of gas expansion energy, which accounts for more than half of the total explosion energy. For many years, the clay used in blasting projects has been kneaded by workers mixing clay at the construction site by...

AI Technical Summary

Problems solved by technology

For many years, the clay used in blasting projects has been kneaded by workers mixing clay at the construction site by hand. The work efficiency is low, the labor intensity is high, the working environment is poor, and the molding of the clay is very irregular, which seriously affects the blasting. Effect

[0003] The blasting machine has the characteristics of on-site construction, easy migration, adjustable output speed, safety and reliability, etc. It solves the mechanization and automation of blasting production and is gradually widely recognized by construction units. Most of the blasting machines currently used are driven by motors. Because the blasting machine has no feeding mechanism, or the feeding mechanism is unreasonable, the phenomenon of "blocking" often occurs, especially in continuous operation, the effect is very unsatisfactory
