Abstract
The utility model discloses a hammer crusher with rapidly replaced grate bars. The hammer crusher comprises a machine shell, a rotor and grate bars, wherein the rotor is arranged in the machine shell; a hammerhead is arranged on the rotor; and the grate bars are arranged around the rotor in the machine shell. The hammer crusher is characterized in that the machine shell comprises a lower shell, an upper shell and two side shells; the upper shell is fixedly connected with the lower shell; a feed inlet is formed in the upper end of the upper shell; and the two side shells are hinged with two sides of the upper end of the lower shell through pin shafts respectively, and are connected with the upper shell through fasteners. The hammer crusher also comprises two hydraulic start-stop devices, wherein the two hydraulic start-stop devices are fixed on two sides of the lower shell respectively; expansion links of the hydraulic start-stop devices are connected with the side shells. The shell of the hammer crusher is divided into several parts, and the side shells can be independently and freely opened through hydraulic systems, so that the grate bars can be replaced more simply and easily.
Description
Technical field
The utility model relates to a kind of hammer mill, a kind of specifically hammer mill of fast changeable grating.
Background technology
Hammer mill often is used to the grinding and processing of various mineral.Traditional hammer mill comprises motor, main shaft, tup, crusher chamber and hopper, and the hammer that is used for break mined material is positioned at crusher chamber and is fixed in main shaft, and under the drive of motor, the main shaft band hammer rotation at a high speed in crusher chamber.Bottom in crusher chamber is provided with sieve plate, discharges through sieve plate less than the grade of screen size in the comminuting matter, on sieve plate, continues to receive the strike and the grinding of hammer greater than the coarse fraction detention of screen size, at last through outside the sieve plate discharge machine.At present, the reversible hammer mill on the market is divided into no grating and two kinds of full gratings, changes down liner plate, grating difficulty down, need employ crane gear such as crane and hang out upper spider, changes trouble, and is long in time limit.
The utility model content
The purpose of the utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of hammer mill of fast changeable grating is provided.
The utility model is the deficiency that solves the problems of the technologies described above, and the technical scheme that is adopted is: a kind of hammer mill of fast changeable grating comprises casing, rotor and grating; Rotor is arranged in the casing; Rotor is provided with tup, grating be arranged on the casing internal rotor around, it is characterized in that: said casing comprises lower house, upper shell and two side bodies; Upper shell is fixedly connected with lower house; The upper shell upper end is provided with charging aperture, and two side bodies are hinged through the both sides of bearing pin and lower house upper end respectively, and two side bodies are connected with upper shell through securing member.
Said hammer mill also comprises two hydraulic opening-closing devices, and two hydraulic opening-closing devices are fixedly installed on the lower house both sides, and the expansion link of hydraulic opening-closing device is connected with side body.
The utility model is split as several parts with the housing of hammer mill, through hydraulic system can be independently random open side housing, it is more simple to change grating.
