Abstract

The utility model discloses an arm-hammer type crusher which is a machines used to pulverize the material. The prior crusher generally uses a plurality of kinds of crushing methods in the squeezing, the splitting, the breaking off, the grinding and the shock. Some of the prior crushers can integrate the crushing methods in one machine, but the turntable is directly provided and rigidly connected with a ring hammer produces small rotational inertia and big rotor weight. The utility model provides a new design scheme of an arm-hammer type crusher which comprehensively utilizes the crushing methods. A hammerhead jib is additionally arranged between the turntable and the ring hammer, and the hammerhead jib is connected with the turntable by a pin, which can effectively use the kinetic energy kinetic energy. The utility model has the advantages of small volume, light weight, low cost, electricity saving, material saving and strong adaptability to the graininess of the material requiring to crush.

Description

Arm-hammer type crusher

The arm hammer mill is a kind of machinery of comminuting matter.

Existing material breaking method has following several: the one, material is placed between two broken working faces, by attrition crushing, as double-roll crusher; The 2nd, with the working face pressing materials of band arris edge, material by bending, action of pulling stress and fragmentation, as jaw crusher; The 3rd, material is subjected to ablation and produces detrusion and be broken between the mechanical surface that relatively slides, as the overhang roll pulverizer; The 4th, the strike that material is stressed and fragmentation, as hammer mill and impact breaker, above-mentioned existing disintegrating machine is general only to have utilized several in the aforementioned breaking method simultaneously, fail to fully utilize simultaneously extruding, stretching, bending, shear, hit multiple breaking method, can not make full use of the operating efficiency of the kinetic energy and the raising equipment of equipment.

The purpose of this utility model is: a kind of arm hammer mill design that fully utilizes multiple breaking method is provided, effectively makes full use of the kinetic energy of equipment, improve the operating efficiency of disintegrating machine, save the machine material, cut down the consumption of energy and the device fabrication cost.

Specific embodiments of the present utility model is: the arm hammer mill is made up of belt pulley, rotating shaft, rotor, flywheel, body, sieve plate, sieve plate frame, crushing shell, cover, control panel and magnet, flywheel is fixedlyed connected with rotating shaft with belt pulley, and rotor is made of round turntable, hammerhead jib and ring hammer.A plurality of round turntables are housed in the rotating shaft, and rotating disk is rigidly connected by key and rotating shaft, is equipped with manyly to hammerhead jib between per two rotating disks, and rotating disk and hammerhead jib flexibly connect with bearing pin, connects a ring hammer on every pair of hammerhead jib, and hammerhead jib flexibly connects with bearing pin with the ring hammer.Rotating shaft is installed in by double row self aligning spherical roller bearing in the bearing block of body, and bearing cap is arranged on the bearing, and seals with sealing gasket.The sieve plate frame is installed on the body by bearing pin one end, and the other end is contained on the cover, and sieve plate and toothed crushing shell are contained on the sieve plate frame, and two blocks of magnet are equipped with at the material inlet place, and control panel is housed.The diameter of ring hammer centre bore connects the diameter of bearing pin greater than it, between bearing pin center line and the ring hammer center line centering error distance is arranged, the ring hammer can not only produce transport motion by countershaft, but also can produce relative motion to rotating disk, ring is hammered the son revolution that not only rotates into shape simultaneously, and around the bearing pin rotation.Ring hammer outer surface is that odontoid or light are planar, and the ring hammer is cast with potassium steel and formed.

Motor is by belt drives belt pulley, rotating shaft and rotor high-speed running, and the ring hammer is also done rotation around bearing pin except that with the rotor high-speed revolution.After material is sent material into crushing chamber from feeding mouth by control panel, it is in accepts broken optimal site, and hit and fragmentation by the ring hammering of rotation at a high speed, control panel has prevented that material is broken and directly fall to sieve plate from feeding mouth without hammering, and the material after the fragmentation of having avoided again overwhelming produces to charging aperture regurgitates phenomenon.Material after the fragmentation makes material be subjected to stretch and splitting because of the kinetic energy that obtains from ring hammer flies to toothed crushing shell at a high speed, is subjected to crooked and fractures, and obtains the fragmentation second time; Simultaneously, material produces bump with the material that rebounds from crushing shell in flight course, obtains broken for the third time, when material drops on the sieve plate, be subjected to encircling extruding, shearing and the grinding of hammer and sieve plate again, obtain the 4th fragmentation, at this moment, qualified products are discharged from the sieve plate hole.

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment:

The arm hammer mill is made of belt pulley 14, rotating shaft 1, rotating disk 2, hammerhead jib 3, ring hammer 4 bodies 7, sieve plate frame 8, sieve plate 9, cover 10, crushing shell 11, control panel 17, magnet 12 and flywheel 18, flywheel 18 is fixedlyed connected with rotating shaft 1 with

belt pulley

14,5 round turntables 2 are housed in the rotating shaft 1, rotating disk is rigidly connected by key 16 and rotating shaft, 2 of per two round turntables are equidistant movable by adorning 4 pairs of hammerhead jibs 3 with bearing pin, totally 16 pairs of hammerhead jibs, flexibly connect a ring hammer 4 with bearing pin on every pair of hammerhead jib 3, ring hammer outer surface has planar two kinds of odontoid, light.Rotating shaft is installed in double row self aligning spherical roller bearing in the bearing block of body 7, and bearing cap is arranged on the bearing, and seals with sealing ring.The two ends of sieve plate frame 8 are installed in respectively on cover 10 and the body 7 with bearing pin 15 and bearing pin 6, and sieve plate 9 and toothed crushing shell 11 are contained on the sieve plate frame, and two blocks of magnet 12 are equipped with at the material inlet place, and control panel 17 is housed.
