Abstract

The utility model provides an adjustable crusher which is characterized in that hammer handles are connected with a rotor wheel hub by adopting a dovetail type connection way. The protruding steps of the hammer handles are clamped in the flute of the wheel hub, and a chamfer head screw used by an oblique iron to imbedding and pressing is tightly fixed on the wheel hub. Widened hammer heads are arranged in shape of an interphase herringbone shape on the circumferential surface of the rotor. A 30 degrees bottom counterattack plate is arranged on the bottom of the box body along the direction of the parabola. The adjustable crusher is an environment protection typed crusher having the advantages of energy saving, energy consumption reducing, convenient manufacturing and repair, high integral strength, small and uniform crushing fineness degree, reliable safety, high fineness and energy saving.

Description

Adjustable disintegrating machine

Technical field

The utility model relates to a kind of material crusher, and particularly a kind of improvement of rotator type disintegrating machine is suitable for the fragmentation of cement life, grog, the fragmentation of building stones in thermal power generation, metallurgy, the refractory material brick field concrete, and the fragmentation of chemical fertilizer factory's material.

Background technology

Chinese patent disclosed " helical rotor formula the disintegrating machine " (patent No.: 99232333.9), though be widely used and produced good effect, but through practice in a few years, find that still the hammer handle parts are made, maintenance difficulty is big, again owing to only fix, as be subjected to impacting energetically the danger that has fracture by four screws; Its two, machine is in running, some blocks that leak to grind drop in the broken material, can influence the quality of grinding.

Summary of the invention

The purpose of this utility model is to provide a kind of adjustable disintegrating machine that can overcome the said equipment shortcoming effectively.

Technical solution of the present utility model is: comprise the casing with charging aperture and discharging opening, the rotor that links to each other with the engine power transmission shaft in the casing, the hammer handle that links to each other with rotor, the tup that links to each other with hammer handle link to each other with casing and rotate counterpunch board, backplate, abrasive sheet and the abrasive sheet clearance adjustment mechanism that tup matches.Be characterized in that hammer handle and rotor hub adopt dovetail type to be connected: the hammer handle raised step is stuck in the groove of wheel hub, wedge embedding pressure is fastened on the wheel hub with sunk screw.

Described parabola direction on bottom half is provided with the end counterpunch board at 30 ° of angles.

The described tup of widening is alternate circular array on the periphery of rotor.

For the sealing crusher chamber, be provided with scalping plate, upper guard board, arc backplate and side guard plate and carse, medium and small counterpunch board in it in the described casing.

Described abrasive sheet clearance adjustment mechanism adopts constant force to adjust structure.

Useful good effect of the present utility model: the scalping plate of newly enabling can make the load of disintegrating machine reduce 5%-15%, thereby has reduced energy consumption; Hammer handle and rotor hub adopt being connected of dovetail type hammer handle, make the location more accurate, have effectively guaranteed the rotating diameter of design rotor, and make processing, maintenance convenient, far super former design, safe and reliable of bulk strength; Tup is alternate circular array and forms the crumbling method that pointwise is hit on the periphery of rotor, reduced energy consumption, eliminated produce because of resistance is excessive that vexed car causes burning out motor may; Backplate partly contains tup, makes the disintegrating machine sealing property better, has stopped big material and has leaked broken possibility; Thin three districts are broken in thick, make broken material more tinyly, even broken; The setting of end counterpunch board does not influence the discharge of wet feed, make in running some leak the block that grinds strikeed back again broken again in the crusher chamber, like this significantly reduced leak broken material, especially effect is more remarkable in the process of beating sand; Consumable accessory tup and abrasive sheet adopt the manufacturing of special, wear-resistant material, make more formerly improve 1.5-3 doubly with material its service life; The constant force adjustment structure, make gap between adjustable abrasive sheet and tup adjust to optimum state, be not subjected to consumable accessory influence (having cancelled the used active sieve plate combination of former disintegrating machine), make particle size after cracking reach best requirement simultaneously; The powerful wind-force that produces during design and the rotor rotation of sealing crusher chamber produces one suction, the dust overwhelming majority is adsorbed onto storing frame place under the disintegrating machine, so this machine is again a kind of environment-friendly type equipment all side of casing.This machine is furnished with overload interlock protector in addition.When disintegrating machine is worked, there is non-broken thing to enter disintegrating machine or other reason when causing the disintegrating machine overload running, that this protector can cut off automatically is two broken, conveyer and a broken power supply, makes device security.

Description of drawings

Fig. 1 is a structure diagrammatic cross-sectional view of the present utility model.

Fig. 2 is the enlarged drawing that hammer handle is connected with rotor hub among Fig. 1.

Fig. 3 is that Fig. 1 rotor and circumference upper ram thereof are arranged expanded view.

The specific embodiment

Be described in further detail it below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, Fig. 3: this machine comprises the casing 1 with charging aperture 7 and discharging opening 6, the rotor 3 that links to each other with engine drive shaft (being provided with bearing block 2) in the casing 1, the hammer handle 4 that links to each other with rotor 3, the tup 5 that links to each other with hammer handle 4, link to each other with casing 1 and rotate the counterpunch board that tup 5 matches, backplate, abrasive sheet 15 and abrasive sheet 15 clearance adjustment mechanisms, this structure is that constant force spring 17 is housed on adjusting yoke 20, spring base 16, constant force spring adjusting nut of adorning respectively inside and outside box body wall 18 and constant force spring are regulated bolt 19, clearance adjusting nut 21 and locking nut 22.Be characterized in that hammer handle 4 and rotor 3 wheel hubs adopt dovetail type to be connected, the tup of widening 5 is alternate circular array on the periphery of rotor 3, and the parabola direction on casing 1 bottom is provided with the end counterpunch board 23 at 30 ° of angles.Dovetail type connects, and is that the hammer handle raised step is stuck in the groove of wheel hub, wedge 24 embeddings are pressed and are fastened on the wheel hub with two sunk screws.For the sealing crusher chamber, be provided with carse, medium and small counterpunch board (12,13,14) in it in the casing 1, arc backplate, upper guard board, side guard plate (9,10,11), scalping plate 8, backplate contain tup 5, make the better and energy savings of sealing property.Abrasive sheet 15 clearance adjustment mechanisms adopt constant force to adjust structure.Through above-mentioned improved structure, make it effectively overcome the shortcoming of prior art.This machine has designed and has produced high meticulous, energy-saving and environmental protection type series of products.The plurality of specifications product is arranged, and its effect is: material size＜60-120mm, discharging-material size＜3--6mm.
