The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

The active roll that few-roller multiple-crushing machine described in the utility model comprises drive motors 1, is in transmission connection by transmission mechanism and drive motors 1.Described active roll is installed on the frame 3 by bearing and central shaft 2 levels, also by bearing idle roll is installed on the frame 3.Initiatively the center at roll and idle roll two ends all is equipped with central shaft 2, and bearing set on the central shaft 2 can rotate freely active roll or idle roll.Wherein initiatively roll and drive motors 1 are in transmission connection, the form that is in transmission connection can have multiple, as shown in Figure 1-Figure 3, the output of drive motors 1 is connected to reductor 9, and the output of reductor 9 is connected on one of them central shaft of active roll by shaft joint again; Certainly, initiatively the mode of being in transmission connection of roll and drive motors 1 can also adopt other being in transmission connection of existing known technology, and does not narrate one by one at this.Described idle roll be positioned at roll initiatively directly over or under, initiatively on the central shaft of roll and idle roll belt pulley is installed all, be set with driving belt on this belt pulley, like this, can active roll and idle roll be coupled together by belt, drive the idle roll rotation by the active roll.

Embodiment of the present utility model can adopt the structure of three rolls, also can adopt the structure of four rolls.

As an embodiment of the present utility model, when adopting three rolls.Described active roll comprises first roll 4 and second roll 5 initiatively initiatively, idle roll be positioned at first initiatively roll 4 or second initiatively roll 5 under, second initiatively roll 5 be positioned at first on roll 4 one lateral deviations or the position on the lower side initiatively.Like this, the first active roll 4 and the second active roll 5 and idle roll are triangularly arranged, and promptly the axis of the axis of the second active roll 5 and the first active roll 4 and idle roll is equidistant.

The diameter of above-mentioned three rolls is identical.

As an improvement of present embodiment, the diameter of active roll 4 of first in above-mentioned three rolls and idle roll is identical, and the first active the roll 4 and second initiatively diameter of roll 5 does not wait.Like this, when three roll seams cooperate the backing ore,, in the backing effect, also have the effect of rubbing because of the former cambered surface of different curvature has different linear velocities, better to the crushing effect of tough ore.Certainly, in actual applications, also can adopt all unequal technical scheme of each roller diameter.

This embodiment adopts three rolls to realize twice backing operation, and employing roll quantity is few, crushing efficiency is high, and product structure is simple, cost is low.

In crushing operation, initiatively roll 4, idle roll are realized matched in clearance to the second active roll 5 with first respectively.For the ease of adjusting the working clearance, active roll or idle roll need be designed to the adjustable structure in position.Initiatively the central shaft of roll or idle roll is installed on the slide block 10 by bearing, and described slide block 10 is installed on the frame 3 by horizontal slide rail, is provided with between slide block 10 and the frame 3 to regulate bolt 8.Just can make slide block 10 move left and right by adjusting adjusting bolt 8, thereby realize the adjustment of active roll or idle roll position.Certainly, in order to keep center line parallel, should on the central shaft at active roll or idle roll two ends, above-mentioned adjusting device be installed all when adjusting the position, and carry out synchronously when adjusting.

Above-mentioned first initiatively roll 4 and second initiatively the diameter of roll 5 can equate, also can be unequal.

As another embodiment of the present utility model.Can also adopt the structure of four rolls.As Fig. 1-shown in Figure 4.Described active roll comprises first roll 4 and second roll 5 initiatively initiatively, described idle roll comprise first idle roll 6, second idle roll, 7, the first idle rolls 6 be positioned at first initiatively roll 4 under; Second idle roll 7 be positioned at second initiatively roll 5 directly over; First initiatively roll 4 with second initiatively roll 5, second idle roll 7 be triangularly arranged, first initiatively roll 4 respectively with the second active roll 5, second idle roll, 7 matched in clearance; Second initiatively roll 5 with first initiatively roll 4, first idle roll 6 be triangularly arranged, second initiatively roll 5 respectively with the first active roll 4, first idle roll, 6 matched in clearance.Above-mentioned each initiatively the upper-lower position relation of roll and idle roll can be provided with arbitrarily, promptly can allow initiatively roll last, idle roll is down, also can idle roll last, initiatively roll is down.

In the present embodiment, also the central shaft of active roll or idle roll can be installed on the slide block 10 by bearing, described slide block 10 is installed on the frame 3 by horizontal slide rail, is provided with between slide block 10 and the frame 3 to regulate bolt 8.

In the above-mentioned present embodiment, the diameter of four rolls is all identical.

As another embodiment of the present utility model, described first active roll 4 and first idle roll, 6 equal diameters, second active roll 5 and second idle roll, 7 equal diameters, the first active the roll 4 and second initiatively diameter of roll 5 does not wait.Like this, utilize two unequal former cambered surface matched in clearance of diameter that ore is carried out backing, there is tiny difference in the linear velocity of rotating because of two former cambered surfaces, also can have certain rubbing action when rolling ore, and is better to the crushing effect of tough ore.

In like manner, can accomplish that three rollers two are broken, five rollers four are broken or the like, so can realize that just broken number of times only lacks one the repeatedly broken theory of few roller than roll quantity.
