But, the inner surface of each body side frame 7 is provided with a pair guide structure body (the 1st guide structure body the 21, the 2nd guide structure body 22) disconnected from each other.Wherein, the 1st guide structure body 21 is configured at the lower section of block 25 described later, and the 2nd guide structure body 22 is configured at the top of block 25.The housing region 23 holding block 25 is formed between the 1st guide structure body the 21 and the 2nd guide structure body 22.
Each guide structure body 21,22 oliquely downward extends towards front (sewing jaw 4 side).The front end of the housing region 23 being formed between 2 guide structure bodies 21,22 is open, and the rear end of housing region 23 is closed by afterframe 24.This afterframe 24 is fixed on rear end and the body side frame 7 of each guide structure body 21,22.Guide structure body 21,22 and afterframe 24 extend from the inner surface of a body side frame 7 to the inner surface of another body side frame 7, and are fixed in pair of side frames 7.
Block 25 is between the 1st guide structure body the 21 and the 2nd guide structure body 22.Block 25 is being contained in the way of pulling out in housing region 23, and can slide relative to each guide structure body 21,22, it is possible to slides along the advance and retreat direction P shown in Fig. 2 relative to guide structure body 21,22 and retreats.
As shown in Figures 1 and 2, each guide structure body 21,22 has: guiding frame 26, it is fixed on body side frame 7；And guide member 27, it is fixed on the inner surface (face of block 25 side) of guiding frame 26, and guide block 25.Block 25 can slide on each guide structure body 21,22 via this guide member 27.As it is shown on figure 3, when observing block 25 from bracket 40 side (when the arrow A along Fig. 2 observes), guide member 27 is arranged in the both ends of block 25 and is arranged in over and under.That is, each guide structure body 21,22 has 27,1 blocks 25 of 2 guide members and is guided by 4 guide members 27.Additionally, as shown in Figures 1 and 2, each guide member 27 extends from the front end of housing region 23 towards rear end, as it is shown on figure 3, be formed with the directed section 28 holding corresponding guide member 27 at the both ends of block 25.Corresponding guide member 27 is connected on each directed section 28, and block 25 can guide and slide by guided member 27.Guide member 27 is less relative to the opposing area of block 25 than guide structure body 21,22 relative to the opposing area of block 25, it is possible to reduces the contact area of guide member 27 and block 25, makes block 25 smoothly slide relative to guide member 27.
As shown in Figures 2 and 3, by stop part 30 (locking member) locking for block 25 by backstop bolt 31 (locking bolt) so that the leading section (end of sewing jaw 4 side) of guide structure body 21,22 can be installed in the way of dismantling.In the present embodiment, stop part 30 passes through backstop bolt 31 can be installed on the leading section of guide sections part 27 in the way of dismantling.In the example shown in Fig. 3, guide member 27 is rectangular shape when being formed as from forward observation, and stop part 30 is formed as toroidal, and stop part 30 has the diameter stretched out from guide member 27.Thus, the block 25 of the front end being positioned at housing region 23 is locking by stop part 30, it is therefore prevented that block 25 is pulled out from housing region 23.On the other hand, by dismantling stop part 30, it is possible to block 25 is pulled out.
As it has been described above, stop part 30 is for preventing the block 25 being positioned at the front end of housing region 23 from being pulled out from housing region 23.Thus, as long as backstop bolt 31 has the intensity that the block 25 of the front end that can will be located in housing region 23 is bearing in the degree of its position.Additionally, the deadweight being located in the block 25 of the front end of housing region 23 is born by the 1st guide structure body 21 and each stop part 30 of downside.Thereby, it is possible to born the major part of the deadweight of block 25 by the 1st guide structure body 21, it is possible to alleviate the load being applied to stop part 30.Therefore, stop part 30 and backstop bolt 31 are reduced the intensity of necessity, it is possible to reduce the size of backstop bolt 31.
As shown in Figures 1 and 2, bracket 40 is between sewing jaw 4 and block 25.Bracket 40 for applying the oscillating motion relative to fixing tooth 3 to sewing jaw 4.The leading section of bracket 40 and rearward end are formed as bending, and the leading section of bracket 40 carries out sliding motion relative to sewing jaw 4, and the rearward end of bracket 40 carries out sliding motion relative to block 25.
More specifically, anterior elbow sheet 41 it is provided with at the rear portion of sewing jaw 4.As in figure 2 it is shown, this front portion elbow sheet 41 has anterior concavity face 42, the leading section of bracket 40 abuts with this concavity face, front portion 42.When the side of the eccentric rotary axis of sewing jaw 4 looks up, anterior concavity face 42 is formed as concavity and bending, and the leading section of bracket 40 is connected on this concavity face, front portion 42 and carries out sliding motion along anterior concavity face 42.
As shown in Figures 1 and 2, block 25 has elbow block 43 and is located at the anterior rear portion elbow sheet 44 of elbow block 43.Wherein, as in figure 2 it is shown, rear portion elbow sheet 44 has concavity face, rear portion 45 (concavity face), the rearward end of bracket 40 abuts with this concavity face, rear portion 45 (concavity face).When the side of the eccentric rotary axis of sewing jaw 4 looks up, concavity face, rear portion 45 is formed as concavity and bending, and the rearward end of bracket 40 is connected on this concavity face, rear portion 45 and carries out sliding motion along concavity face, rear portion 45.
As shown in Figures 3 and 4, when observing block 25 from bracket 40 side, the centrage C1 in concavity face, rear portion 45 is eccentric relative to the centrage C2 of housing region 23 in the vertical direction.In the example shown in Fig. 3, the centrage C1 in concavity face, rear portion 45 is eccentric upward relative to the centrage C2 of housing region 23.As described later, by this block 25 is pulled out from housing region 23, it is possible to make above-below direction reverse.Figure 4 illustrates the block 25 of reversion, here, the centrage C1 in concavity face, rear portion 45 is eccentric downwards relative to the centrage C2 of housing region 23.Additionally, the centrage C1 in concavity face, rear portion 45 refers to the line that the above-below direction center through concavity face, rear portion 45 direction along eccentric rotary axis extend, and the centrage C2 of housing region 23 refers to through the above-below direction center of housing region 23 and at the upwardly extending line in the side of eccentric rotary axis.
Bracket 40 is pressed to block 25 side by the rearward pull strength being applied to sewing jaw 4 by above-mentioned pull bar 11, and block 25 is pressed to afterframe 24.The bottom of sewing jaw 4 is forwards pressed by bracket 40 under the effect of counteracting force.Further, bracket 40 is retrained by anterior elbow sheet 41 and rear portion elbow sheet 44, thus not coming off from anterior elbow sheet 41 and rear portion elbow sheet 44.
As shown in Figures 1 and 2, a pair wedge parts 46 is between elbow block 43 and afterframe 24.These wedge parts 46 for adjusting the outlet gap (gap between the lower end of the lower end in the mountain portion of fixing tooth 3 and the valley of movable teeth 6) of crushing chamber 5 by the position of the advance and retreat direction P of adjustment elbow block 43.
That is, as shown in Figures 5 and 6, each wedge parts 46 have relative to the advance and retreat direction P of the elbow block 43 wedge surface 46a tilted, and wedge surface 46a can slide each other.Additionally, the gap being linked with the outside being located at body side frame 7 on each wedge parts 46 adjusts cylinder 47, each wedge parts 46 can move up in the side vertical with the advance and retreat direction P of elbow block 43.By such structure, each wedge parts 46 are driven by gap adjustment cylinder 47 and above move in the direction (left and right directions in Fig. 5 and Fig. 6) vertical with advance and retreat direction P, thus adjust the position, advance and retreat direction of elbow block 43, thus adjusting the size of the outlet gap of crushing chamber 5.
It follows that the effect of the present embodiment being made up of such structure is illustrated.
When treated object S is crushed, first, not shown drive division is driven, and this driving force passes to belt wheel 9 via conveyer belt.Thus, sewing jaw 4 eccentric rotary.
In the period of sewing jaw 4 eccentric rotary, the bottom of sewing jaw 4 is applied in the pull strength of spring 10, and the bottom of sewing jaw 4 is pressed to bracket 40.Thus, the bottom of the movable teeth 6 being located on sewing jaw 4 carries out oscillating motion relative to fixing tooth 3.
It follows that put into the treated object S as raw material to crushing chamber 5, by the oscillating motion of movable teeth 6, the treated object S of input is compressed broken successively.In the treated object S broken by compression, it is possible to discharged from the outlet of crushing chamber 5 as broken product by the treated object S of the size of the outlet of crushing chamber 5.
In the period carrying out break process, the bottom of movable teeth 6 swings in the stroke of regulation in the way of describing ellipse, but, owing to the short axle of this ellipse is shorter, therefore, outline, it is possible to be considered as swinging point-blank.
In the figure 7, it is schematically shown the situation of the oscillating motion of the bottom of movable teeth 6.The positional representation movable teeth 6 that (Fig. 1 is too) is shown in solid in the figure 7 is apart from the farthest position of fixing tooth 3.In this case, the tilt angle theta (angle with respect to the horizontal plane) of bracket 40 becomes relatively larger, represents that the bottom of sewing jaw 4 is drawn into rear.On the other hand, the positional representation movable teeth 6 shown in two chain-dotted lines is apart from the nearest position of fixing tooth 3.In this case, the angle of inclination of bracket 40 becomes smaller, represents that the bottom of sewing jaw 4 is subject to the counteracting force of bracket 40 and is pushed forward in.
Further, in the figure 7, size L1 the outlet gap of crushing chamber 5 is represented.By adjusting the outlet gap of crushing chamber 5, it is possible to adjust the size of broken product.When adjusting the outlet gap of crushing chamber 5, as it has been described above, drive gap to adjust cylinder 47 adjust the position of wedge parts 46, thus adjusting the position of the advance and retreat direction P of elbow block 43.
Additionally, in the figure 7, size L2 the stroke of the bottom of movable teeth 6 is represented.Stroke mentioned here refers to the distance on the direction vertical with the flank of tooth of movable teeth 6 in the quantity of motion of the bottom of the valley of movable teeth 6.
By adjusting the stroke of the bottom of movable teeth 6, it is possible to be set as stroke corresponding with the character of treated object S, thus efficiently treated object S being crushed.It also is able to efficiently processed portion be crushed additionally, adjust stroke according to the gap of above-mentioned crushing chamber 5.And then, it is also possible to prevent from being caused that jaw crusher 1 damages by counteracting force when compressing.Therefore, below, as being used for adjusting the decomposition assembling operation method of the stroke of the bottom of movable teeth 6, the method making block 25 be inverted to the state shown in Fig. 4 from the state shown in Fig. 3 is illustrated.
First, when drive division stops, the cylinder 14 of the active force for adjusting spring 10 is driven, and pull bar 11 discharges from the active force of spring 10.Thus, bracket 40 from applied by sewing jaw 4 by earth pressure release.
It follows that make the bottom of sewing jaw 4 to fixing tooth 3 side shifting, dismantle bracket 40 from anterior elbow sheet 41 and rear portion elbow sheet 44.Now, block 25 due to from applied by bracket 40 by earth pressure release, therefore under the effect of its deadweight, the front end to the housing region 23 being formed between the 1st guide structure body the 21 and the 2nd guide structure body 22 is moved.Arrive the block 25 of front end of housing region 23 engaging in stop part 30, and rest in housing region 23.
It follows that loosen and unload backstop bolt 31, stop part 30 is unloaded from guide member 27.Thus, block 25 is pulled out from housing region 23.
It follows that reversed by the block 25 of pull-out in the vertical direction, and it is inserted into housing region 23.
Hereafter, the step reverse step carrying out with pulling out before above-mentioned block 25, decompose assembling operation and terminate.
When decomposing assembling operation and terminating, as shown in Figure 4, when observing block 25 from bracket 40 side, the centrage C1 in the concavity face, rear portion 45 of the rear portion elbow sheet 44 of block 25 is eccentric downwards relative to the centrage C2 of housing region 23.That is, block 25 is reversed after the centrage C1 in concavity face, rear portion 45 reverse than by block 25 before offset downwards.Owing to concavity face, rear portion 45 is formed as concavity, the rearward end of bracket 40 is being connected on concavity face, rear portion 45 in the way of sliding motion, therefore, along with the skew of the centrage C1 in concavity face, rear portion 45, the position of the rearward end of bracket 40 reverse than by block 25 before position offset downwards.Therefore, the tilt angle theta of bracket 40 diminishes, and the bottom of sewing jaw 4 is forwards released by bracket 40, and the amount of drawing in that the bottom of sewing jaw 4 is rearward drawn in is limited.Its result, the stroke of the bottom of movable teeth 6 reduces.
On the other hand, before block 25 is reversed, as it is shown on figure 3, the centrage C1 in the concavity face, rear portion 45 of rear portion elbow sheet 44 is eccentric upward relative to the centrage C2 of housing region 23, the position of the rearward end of bracket 40 reverse than by block 25 after position above.Therefore, the tilt angle theta of bracket 40 becomes big, and it is big that what the bottom of sewing jaw 4 was rearward drawn in draws in quantitative change.Its result, the stroke of the bottom of movable teeth 6 increases.
