Abstract

The utility model provides an adjustable fine crusher used in industrial departments, such as building materials, chemical industry, mining and refractory, etc. comprising a box body containing a feed poet and an impact chamber and at least one impact chamber containing an impact plate positioned between the feed port and the impact chamber. A main shaft is arranged on the box body. A hub positioned in the impact chamber and arranged on the main shaft is provided with a hammer head. The utility model is characterized in that a constant force adjusting mechanism arranged at the gap between the adjusting hammer head and the impact plate is positioned in the impact chamber. The adjustable fine crusher can adjust the gap between the impact plate and the hammer head and extend the service life of the wearing parts.

Description

Adjustable high fine crushing machine

The utility model relates to a kind of material crusher, particularly be a kind of adjustable high fine crushing machine that is used for industrial departments such as building materials, chemical industry, mining and refractory material.

The casing that contains charging aperture and impact the chamber is arranged in the existing high fine crushing machine, at least one that is positioned between charging aperture and impact chamber contains the back cavity of counterpunch board, main shaft is loaded on the casing, and being positioned to impact the chamber and be loaded on the wheel hub on the main shaft has tup, is positioned in the casing to impact the chamber and locate to have sieve plate.Disintegrating machine in use, because the wearing and tearing between tup and various consumable accessory such as tup, sieve plate, counterpunch board, the gap of tup and counterpunch board, sieve plate increases, enter and impact chamber raw meal particle size chap, the motor cycle load increases, tup and sieve plate produce fretting wear and increase, the shortening in service life of various consumable accessory, and can not guarantee discharging-material size.

In view of above reason, the purpose of this utility model is in order to overcome above deficiency, to provide a kind of and can regulate gap between counterpunch board and tup, improving the consumable accessory adjustable high fine crushing machine in service life.

The purpose of this utility model is achieved like this: the utility model is the improvement on existing high fine crushing machine, the cavity that contains charging aperture and impingement box is arranged, at least one that is positioned between charging aperture and impact chamber contains the back cavity of counterpunch board, main shaft is loaded on the casing, being positioned to impact the chamber and be loaded on the wheel hub on the main shaft has tup, it is characterized in that being positioned at the constant force governor motion (referring to Fig. 1, Fig. 3) that there is gap between adjusting tup and counterpunch board at the back cavity place.

In the above-mentioned constant force governor motion regulating box that is connected with casing is arranged, be positioned at counterpunch board the place and slidably adjustable counterpunch board, one end stretches in the regulating box and the spring pull bar hinged with adjustable counterpunch board, be contained in the spring base (22,23) on the spring pull bar, be positioned between spring base and be loaded on compression spring on the spring pull bar, regulate the bolt sky to be enclosed within on the spring pull bar and be pressed on spring base (22) on and be threaded on the regulating box, the constant force adjusting nut is threaded on the spring pull bar and is pressed on the adjusting bolt (referring to Fig. 1).

Above-mentioned adjustable counterpunch board is circular arc tooth plate (referring to Fig. 1), and the tooth on the circular arc tooth plate is that line contacts with material, grinds, crushing effect is good.

Above-mentioned lower box has discharging opening (referring to Fig. 1), can remove sieve plate, reduces cost.

During the utility model work, after material enters tup strike district, be subjected to rotate at a high speed tup and hit the upper and lower of clashing into back cavity behind the acquisition kinetic energy, pulverize through strikeing back most of materials, the material that do not mince enters to regulate and carries out impact comminution between counterpunch board and tup once more, and the material after the pulverizing is discharged through the lower box discharging opening.(diameter≤when 80mm) passing through adjustable counterpunch board, adjustable counterpunch board compression compression spring strengthens the gap between adjustable counterpunch board and tup, and excessive iron block is got rid of from the lower box discharging opening through behind this gap when excessive iron block.

Compare with existing high fine crushing machine, the utlity model has following advantage:

1., reduced frictional force between material and the tup, non-broken material can not cause device damage after entering this machine, has increased the service life of tup and consumable accessory;

2., according to operating mode conditioning equipment gap at any time, discharging-material size can be effectively controlled, and reduces the motor cycle load, and power consumption power descends greatly;

3., do not need the combination of sieve plate and active sieve plate in principle, reduced cost.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is another structural representation of the utility model.

Embodiment 1:

Fig. 1, Fig. 2 have provided embodiment 1 structural representation.Casing 1 comprises and contains charging aperture 2, upper box 3 and pass through connector---the lower box that contains discharging opening 45 that bolt is attached thereto.Charging aperture 2 and horizontal plane angle α=50 °.In first back cavity 6 in the upper box 3 counterpunch board 7 that is contained on the casing is arranged, big flat tooth plate 8.Counterpunch board 10, circular arc tooth plate 30 are arranged in second back cavity 9.Be contained on the casing and be positioned on the end that the main shaft 12 that impacts chamber 11 stretches out casing belt pulley 13 arranged, belt pulley 13 is connected with motor by driving belt.Wheel hub 14 is housed on the casing inner main axis, not at grade the hammer carrier 15 of several cross arrangements is housed on the wheel hub 14, several tups 16 pass through connector respectively---and bolt 17, nut 18 are tightly packed on several hammer carriers, and tup is wider than hammer carrier.Regulating box 29 in the constant force governor motion 19 is connected on the casing, but adjustable counterpunch board---circular arc tooth plate 20 is contained in casing counterpunch board 10 places and horizontal slip, and spring pull bar 21 1 ends stretch in the regulating box and be hinged with adjustable counterpunch board.22,23 of spring bases that are contained on the spring pull bar 21 have compression spring 24.Gap adjustment bolt 25 skies are enclosed within on the spring pull bar and press closer on spring base 22 end faces and be threaded on the regulating box, and constant force adjusting nut 26 is threaded on the spring pull bar and presses closer on gap adjustment bolt 25 end faces.

Embodiment 2:
