Detailed Description

In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.

As shown in fig. 1-2, the utility model provides a lower silo for jaw crusher, lower silo 4 sets up in the broken chamber 3 top between movable jaw 1 and quiet jaw 2.

The lower trough 4 is of a horn-shaped structure with a thick upper part and a thin lower part and comprises an upper section 5, a middle section 6 and a lower section 7, wherein the upper section 5 and the lower section 7 are square tubes, the caliber of the square tube of the upper section 5 is larger than that of the square tube of the lower section 7, and the upper section 5 is connected with the lower end through the conical middle section 6. The lower end opening of the lower section 7 square tube is connected to the frame 16 of the jaw crusher.

When the jaw crusher is in a non-working state, the upper end opening of the crushing cavity 3 is surrounded by the lower end opening of the lower section 7 square tube, and the movable jaw plate 1 moves below the lower end opening of the lower section 7 square tube.

The lower edge of the outer end face of the side wall of the lower section 7 square tube close to one side of the static jaw plate 2 is provided with a door shaft 8, the axis of the door shaft 8 is parallel to the static jaw plate 2, and the blanking groove 4 is rotatably connected to a rack 16 of the jaw crusher through the door shaft 8. When the blanking groove 4 rotates to be in contact with the rack 16, the opening at the lower end of the blanking groove 4 seals the opening at the upper end of the crushing cavity 3; when the lower trough 4 rotates to be far away from the machine frame 16, the opening at the upper end of the crushing cavity 3 is opened, and the static jaw 2 can be replaced.

The upper edge of the static jaw plate 2 exceeds the upper end surface of a rack 16 of the jaw crusher, and two clamping grooves 9 are symmetrically arranged on one side, close to the static jaw plate 2, of the lower end opening of the blanking groove 4. When lower silo 4 rotated to contact with frame 16, the top edge joint that quiet jaw 2 surpassed carries out a suppression to quiet jaw 2 through the gravity of lower silo 4 self in two joint grooves 9, prevents that quiet jaw 2 from taking place to rock in work.

The upper end face of the machine frame 16 at one side of the static jaw plate 2 is provided with a supporting arm 11, and the lower end of the supporting arm 11 is hinged with the upper end face of the machine frame 16 through a hinge seat 10. A pin shaft seat 12 is fixedly arranged on the outer side face of the side wall of the middle section 6 of the discharging groove 4, which is close to one side of the static jaw plate 2, and a pin hole is arranged at the upper end of the supporting arm 11. When the lower trough 4 rotates to contact with the rack 16, the upper end of the supporting arm 11 rotates to the position of the pin shaft seat 12, the pin hole corresponds to the pin shaft seat 12, the pin shaft is inserted through the supporting arm 11 and the pin shaft seat 12, the supporting arm 11 is fixedly connected with the lower trough 4, and the supporting arm 11 pushes up the lower trough 4 to enable the lower trough 4 not to rotate towards the direction far away from the rack 16, so that the lower trough 4 is fixed on the rack 16.

The left side and the right side of the crushing cavity 3 are respectively provided with a movable jaw plate 1 and a static jaw plate 2, the inner walls of the front side and the rear side of the crushing cavity 3 are respectively provided with a fixed rod 13, the right end of the fixed rod 13 is provided with a clamping claw 14, and the clamping claw 14 is clamped at the upper edge of the static jaw plate 2. The middle part of dead lever 13 is provided with a bolt 15 via hole, be provided with a platform respectively on the front and back both sides inner wall in broken chamber 3, be provided with a screw hole on the platform, bolt 15 passes behind the bolt 15 via hole on dead lever 13 and the screw hole spiro union on the platform to be fixed in dead lever 13 on the inner wall in broken chamber 3, simultaneously because joint claw 14 and quiet jaw 2 upper limb looks joint, consequently dead lever 13 after the fixing plays a spacing effect to quiet jaw 2, prevent that it is not hard up at the during operation.

Jaw crusher is at the during operation, fixes dead lever 13 to rotate feed chute 4 and contact with frame 16, can be with the raw materials through feed chute 4 leading-in to crushing chamber 3 inside crushing like this.

The opening at the upper end of the feeding chute 4 extends upwards at the edge close to one side of the static jaw plate 2 to form an extending baffle plate, and the falling materials are blocked by the extending baffle plate.

When the static jaw plate 2 needs to be replaced due to abrasion, the pin shaft at the upper end of the supporting arm 11 is pulled out, the supporting arm 11 is rotated to a position far away from the pin shaft seat 12, and therefore the blanking slot 4 can be rotated to a position far away from the rack 16. After the blanking groove 4 rotates, the opening at the upper end of the crushing cavity 3 is exposed, and meanwhile, the blanking groove 4 loses the pressing on the static jaw plate 2. Then the bolt 15 is disassembled, the fixed rod 13 can be taken down, the static jaw plate 2 is loosened after the limitation is completely lost, and the static jaw plate 2 can be taken out for replacement, so that the maintenance and the replacement of personnel are facilitated.

After the static jaw plate 2 is replaced, the fixing rod 13 is fixed through the bolt 15 again, the lower chute 4 is rotated back to be in contact with the rack 16, and finally the supporting arm 11 and the pin shaft seat 12 are fixed mutually, so that the lower chute 4 is reset, and meanwhile, the static jaw plate 2 is also pressed and fixed, and is prevented from shaking in work.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
