Abstract
The utility model relates to a crusher used in underground coal mine, in particular to a planer type quartering hammer shaft assembly. According to traditional crushing equipment, materials are crushed by means of impact force or extrusion force, and thus production particle size is uneven and coal dust rate is high. According to the planer type quartering hammer shaft assembly, a beak type design structure is adopted in the design of a hammer head according to bionics, an external contour of the hammer head is smoothly connected with external contours of separated hammer bodies, the external contour of each separated hammer body is centrally symmetric, the separated hammer bodies at two ends and the separated hammer body in the middle are in square crossing arrangement, and the three separated hammer bodies are connected with a quartering shaft through shaft keys. When the materials are crushed, the fact that the main force direction of the hammer head is the cutting direction of the hammer head is guaranteed, crushing effect is improved, crushing cycle is short, discharging particle sizes are even, coal dust rate is reduced, and service life of the hammer head is prolonged. In addition, the hammer head can be replaced at any time and is simple in operation and affordable.
Description
Technical field
The utility model relates to crushing technology field under coal mine, specifically a kind of plane formula quartering hammer shaft assembly.
Background technology
Under traditional coal mine, disintegrating apparatus is a lot, and the forms such as jaw formula, hammer are arranged, and its operation principle is to lean on impact or extruding force by the material fragmentation, and consequent product granularity is inhomogeneous and the coal dust rate is high.Wherein between two minutes hammer bodies of hammer mill, adopt run-in index to install, the broken cycle is long, and the granularity of bulk media fragmentation is inhomogeneous and the coal dust rate is high.
Summary of the invention
The purpose of this utility model is to provide short, the uniformly efficient plane formula quartering hammer shaft assembly of discharging-material size of a kind of broken cycle, to solve problems of the prior art.
The technical solution adopted in the utility model is: plane formula quartering hammer shaft assembly comprises that broken shaft, minute hammer body, tup, attachment bolt and axle key five parts form; Attachment bolt is fixed on tup respectively the two ends, left and right of minute hammer body; It is characterized in that: tup adopts beak shape structure, tup gabarit and a minute hammer body gabarit smooth connection; Symmetrical centered by minute hammer body gabarit; Minute hammer body of two ends is arranged vertically mutually with the hammer body that divides in centre position, by axle key, three minutes hammer bodies and broken shaft is linked together.
The beneficial effects of the utility model are, because the linkage between minute hammer body has been guaranteed in minute hammer body employing square crossing distribution that divides hammer body and centre position of two ends, to reduce and divide the wearing and tearing of hammer body to axle key; Tup increases to 6 by original 4, so shortened the broken cycle.Tup adopts beak shape project organization according to bionics, tup gabarit and a minute hammer body gabarit smooth connection, that has guaranteed that tup main stress direction is tup when broken is tangential, improves crushing effect, make discharging-material size evenly reduce the coal dust rate, extended the service life of tup.Tup can be changed at any time, easy to operate, economic and practical.

1. broken shafts in figure, 2. attachment bolt, 3. minute hammer body, 4. axle key, 5. tup.
The specific embodiment
As shown in Fig. 1～4, plane formula quartering hammer shaft assembly mainly is comprised of broken shaft 1, minute hammer body 3, tup 5, attachment bolt 2 and axle key 4 five parts, respectively tup 5 is fixed on to the two ends, left and right of minute hammer body 3 with attachment bolt 2, by axle key 4, two minutes hammer bodies 3 are linked together with broken shaft 1, it is characterized in that: tup 5 adopts beak shape structure, tup 5 gabarits and minute hammer body 3 gabarit smooth connections; Symmetrical centered by minute hammer body 3 gabarits; Hammer body 3 square crossings in three minutes are arranged, by axle key 4, three minutes hammer bodies 3 are linked together with broken shaft 1.
During assembling, use bolt that axle key 4 is fixed on broken shaft 1.Then according to the position of axle key 4, will divide hammer body 3 to be assembled on broken shaft 1 according to adjacent two square crossing distribution forms.Finally use attachment bolt 2 that tup 5 is fixed on minute hammer body 3.
