Description

[Detailed Description of the Invention] This invention relates to a distance adjusting device between fixed teeth and movable teeth in an underwater show crusher.

Mud water containing large and small earth and sand flows inside the submersible show crusher, and the fixed teeth and movable teeth that crush the rocks in the muddy water are significantly worn out. The toggle plate 35, which is received between the receiving member 32 on the 31 side and the receiving member 34 on the movable tooth 33 side, is gradually changed to a longer one depending on the amount of wear.

However, this requires the toggle plate 35 to be replaced frequently, and unless a large number of toggle plates 35 are prepared, it is difficult to finely adjust the distance between the fixed teeth and the movable teeth, which reduces work efficiency. there were.

The purpose of this invention is to not only make it possible to adjust the interval from the outside of the underwater show crusher using a predetermined interval adjustment mechanism, but also to isolate this interval adjustment mechanism from dust, etc., in order to solve the above-mentioned problems. To provide a spacing adjustment device that can maintain the

First, the outline of a submersible show crusher equipped with the spacing adjustment device A according to this invention will be explained with reference to FIG. It flows down to the discharge pipe 2 from the introduction pipe 3 connected to the front upper part.

Reference numeral 4 denotes a show crusher provided in a passage for muddy water, and a crushing gap S converging downward between a fixed tooth 5 and a movable tooth 6a of a swinging jaw 6 provided to correspond to the fixed tooth 5. The large rocks contained in the muddy water are finely crushed by vertical and back-and-forth swinging by the swinging jaw 6 and sent to the discharge pipe 2.

Note that 7 is a motor fixed to the outside of the casing 1, and 8 is a tension rod that swingably supports the lower part of the swing jaw 6.

Next, one embodiment of the interval adjustment device A will be described with reference to the drawings. Reference numeral 9 denotes a toggle block holder in the shape of a rectangular parallelepiped container fixed to one side of the casing 1, as shown in FIGS. 2 and 3. As shown in FIG. 2, a gasket 9a is sandwiched between the inner hole 11 opened on the surface facing the toggle plate 22 (to be described later), a side hole 10 communicating with the inner hole 11, and both openings of the side hole 10. A lid 9b fixed to be openable and closable is formed.

12 is the inner hole 11 in the toggle block holder 9.
It is a toggle block in the shape of a rectangular parallelepiped that is installed inside from the open end of the block, and as shown in FIG. A receiving surface 14 is formed.

15 is a setting block interposed between the inner end of the toggle block 12 and the inner top of the toggle block holder 9, and is inserted into the side hole 10 of the toggle block holder 9.
It is removable from the

A setting bolt 16 is screwed into the top wall of the toggle block holder 9 so that it can be operated externally, and its inner end can come into contact with the setting block 15.

Reference numeral 17 denotes a rectangular parallelepiped-shaped protruding position regulating member mounted inward from the open end of the inner hole 11 of the toggle block holder 9 in contact with the toggle block 12,
As shown in FIG.
An upwardly inclined inclined surface 18 is formed in contact with the inclined surface 13 of No. 2, and a wedge means is formed between the toggle block 12 and the toggle block holder 9.

An adjustment bolt 19 is inserted through the top wall of the toggle block holder 9 so as to be able to be operated externally, and its inner end is screwed into the upper surface of the protruding position regulating member 17.

Reference numeral 20 denotes a receiving member fixed to the lower part of the swing jaw 6, and as shown in FIG. 21 is formed.

22 are edges 22a at both the upper and lower outer ends as shown in FIG.
It is a flat toggle plate having a convex receiving surface 23 formed thereon, and the tips of its edges 22 a abut against the concave water receiving surfaces 14 and 23 of the toggle block 12 and the receiving member 20, respectively.

Then, the radius of curvature of the concave receiving surfaces 14, 21 is made larger than the radius of curvature of the convex receiving surface 23, so that the concave receiving surfaces 14, 21 and the convex receiving surface 23 are formed on both sides of the toggle plate 22. A sufficient gap is created between the two.

Note that 24 is a screw hole for lifting the toggle block 12 in the toggle block holder 9 upward.

Next, the adjustment of the interval between the fixed teeth and the movable teeth in this embodiment will be explained.

First, when the adjustment bolt 19 is loosened and then tapped, the protruding position regulating member 17 descends within the toggle block holder 9 in a vertically slidable state.

In this state, when the setting bolt 16 is turned clockwise and screwed in, the toggle block 12 will move as the swing jaw 6 descends until its inclined surface 13 contacts the inclined surface 18 of the protruding position regulating member 17 in the lowered position. and descend in the same way.

Therefore, in this state, a gap is created between the inner top of the toggle block holder 9 and the upper surface of the setting block 15.

If necessary, insert a separately prepared thin shim (not shown) into this gap through the side hole 10 of the toggle block holder 9, so that the toggle block 12 is positioned more protruding from the open end of the toggle block holder 9. Fixed.

Therefore, the swinging jaw 6 is fixed in the lowered position with the toggle plate 22 received between the receiving member 20 and the toggle block 12, and the interval between the movable teeth 6a of the swinging jaw 6 and the fixed teeth 5 is narrowed. be in a state of being

Finally, when the adjustment bolt 19 is tightened, the protruding position regulating member 17 rises, and its inclined surface 18 presses the inclined surface 13 of the toggle block 12, so that the toggle block 12 is completely fixed in position.

Then, the setting bolt 16 is removed from the toggle block holder 9, and a blind bolt is screwed in its place to complete all adjustment work.

In the present invention described in detail above, the container-shaped toggle block holder 9 has an inner hole 11 opened on the surface facing the toggle plate 22, a side hole 10 communicating with the inner hole 11, and a side hole 10 communicating with the inner hole 11. A lid 9b fixed to be openable and closable so as to cover the opening
The inner hole 11 of this toggle block holder 9
includes a receiving portion 14 that receives the toggle plate 22 at its outer end.
The toggle block 12 having a toggle block 12 is mounted so as to be retractable from the open end of the inner hole 11, and a protrusion position regulating member 17 for regulating the protrusion position of the toggle block 12.
Similarly, the toggle block 12 is installed so that it can protrude and retract from the open end of the inner hole 11, and the amount of protrusion and retraction of the toggle block 12 is set between the inner end of the toggle block 12 and the inner top of the inner hole 11 of the toggle block holder 9. A setting block 15 for adjustment is provided, and this setting block 15 is made removable through the opening of the side hole 10 of the toggle block holder 9, so that the setting block 15 of an appropriate width can be inserted through the side hole 10 of the toggle block holder 9. Toggle block 1 in toggle block holder 9 by attaching and detaching
Not only can the position of the toggle block 12 be adjusted, but also fine adjustment can be made by appropriately inserting thin shims in addition to the setting block 15. By fixing the protruding position regulating member 17 that supports the toggle block 12, the toggle block 12 can be adjusted. It can be kept in a fixed state, and the interval between the fixed tooth 5 and the movable tooth 6a can be easily adjusted from the outside of the submersible show crusher using only one toggle plate 22.

Furthermore, since the toggle block 12, setting block 15, and protruding position regulating member 17 are housed in the toggle block holder 9, they are shielded from dust and the like, making it difficult for dust and the like to enter these sliding surfaces. , it also has the effect of maintaining smooth movement.
