Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): the utility model provides an install in hydraulic pressure shearing mechanism of excavator arm, like figure 1 and figure 2, contain the mount 1 of installing at the excavator arm, be equipped with connecting block 4 and lower connecting block 5 on the mount 1 respectively, it is articulated with mount 1 to go up connecting block 4, it has the pneumatic cylinder 7 that is used for driving to go up connecting block 4 along articulated department pivoted in the mount 1 to articulate, the output of pneumatic cylinder 7 is articulated with last connecting block 4, lower connecting block 5 and 1 fixed connection of mount, it is connected with top rest 3 and bottom rest 2 through two connecting pieces 6 that the structure is the same respectively to go up connecting block 4 and bottom connecting block 5. Therefore, when the hydraulic cylinder 7 is started, the upper connecting block 4 is pushed to rotate along the hinged part, so that the upper tool rest 3 is driven to move towards the lower tool rest 2 to realize the shearing action.

As shown in fig. 3, the connecting member 6 on the upper blade holder 3 is configured to: contain fastening bolt 9, upward be equipped with connecting lug 10 on connecting block 4, go up knife rest 3 towards the terminal surface of mount 1 on offer with connecting lug 10 assorted spread groove 11, be equipped with rubber pad 23 on the inner wall of spread groove 11, connecting lug 10 joint is after in spread groove 11, fastening bolt 9 wears to establish spread groove 11 simultaneously and connects lug 10 and bolted connection on last knife rest 3 to realize going up knife rest 3 and last connecting block 4's being connected. The rubber pad 23 reduces the possibility that the connecting lug 10 and the connecting groove 11 are in direct contact and abut tightly, the interaction force between the inner wall of the connecting groove 11 and the connecting lug 10 is too large, so that the connecting lug 10 or the connecting groove 11 deforms, and the connection firmness of the upper tool rest 3 and the upper connecting block 4 is affected. The lower tool rest 2 is connected with the lower connecting block 5 in the same way as the upper tool rest 3.

As shown in fig. 4, a knife slot 12 is formed in the lower knife rest 2, a knife 8 and a fastening block 13 are respectively erected in the knife slot 12, three first through holes 14 are uniformly formed in the back of the knife 8, a T-shaped chute 20 is formed in the bottom of the knife slot 12, a T-shaped protruding edge 19 which is located in the chute 20 and moves along the chute 20 is fixedly arranged on the fastening block 13, three connecting bolts 15 which simultaneously penetrate through the lower knife rest 2, the first through holes 14 and the fastening block 13 are respectively arranged on the lower knife rest 2, and the outer peripheral edges of the connecting bolts 15 are matched with the first through holes 14. Therefore, the worker can place the blade 8 in the blade groove 12, and then respectively screw three connecting bolts 15 penetrating through the lower blade carrier 2, the first through hole 14 and the fastening block 13, so as to drive the protruding edge 19 to move towards the blade 8 along the sliding groove 20 until the fixing block abuts against the blade 8 on the side wall of the blade groove 12, thereby fixing the blade 8 on the lower blade carrier 2, and the installation and fixing modes of the blade 8 on the upper blade carrier 3 are the same as those of the lower blade carrier 2.

As shown in fig. 2 and 4, a worker can start the hydraulic rod to open the upper tool rest 3 and the lower tool rest 2, move to the position of the material to be sheared under the driving of the excavator arm, and start the hydraulic rod to drive the upper tool rest 3 to move towards the lower tool rest 2, at this time, the blades 8 on the upper tool rest 3 and the lower tool rest 2 can shear the material to be sheared, which is positioned between the upper tool rest 3 and the lower tool rest 2. The connecting bolt 15 can be detached regularly by a worker, and is drawn out of the first through hole 14 of the blade 8, and then the blade 8 is detached, so that the blade 8 can be replaced by the worker, and the possibility that the cutting edge becomes blunt after the blade 8 is used for a long time, the cutting effect is influenced, and the cutting efficiency is reduced; the convex edge 19 on the fastening block 13 is positioned in the sliding groove 20, so that when a worker replaces the blade 8, the fastening block 13 is difficult to fall off from the cutter groove 12, and the possibility that the worker inconveniences because the fastening block 13 falls off when the worker replaces the blade 8 is reduced; when needs are cuted the material of equidimension not, the staff can be respectively through carrying out the mode of dismantling to two connecting pieces 6, lift off top rest 3 and lower knife rest 2 respectively, later change the top rest 3 and the lower knife rest 2 of different length to install respectively with the top rest 3 and the lower knife rest 2 assorted blade 8 after changing, thereby realize changing the effect of different length blades 8, so that top rest 3 and lower knife rest 2 can cut the material of different length.

As shown in fig. 4, rotation-preventing holes 16 are respectively formed on the screws of the three connecting bolts 15, second through holes 17 are formed in the fastening block 13 along the length direction, and rotation-preventing bolts 18 simultaneously penetrating through the second through holes 17 and the three rotation-preventing holes 16 are arranged on the fastening block 13. Therefore, after the worker fixes the insert 8 in the pocket 12 by the connecting bolt 15, at this time, the three rotation-preventing holes 16 communicate with the second through hole 17, respectively, the worker can insert the rotation-preventing bolt 18 through the second through hole 17 and the three rotation-preventing holes 16, and then the three connecting bolts 15 are bolted to the fastening block 13, so that the three connecting bolts 15 are difficult to rotate. In the shearing process, the upper tool rest 3 and the lower tool rest 2 shake, and the three connecting bolts 15 rotate along with the shaking, so that the blade 8 is loosened, and the shearing effect is influenced.

As shown in fig. 4, a plurality of arc-shaped grooves 21 are formed at the edge of the blade 8, the plurality of arc-shaped grooves 21 increase the friction force between the blade 8 and the object to be sheared, and reduce the possibility that the material to be sheared slides and is difficult to be sheared due to the extrusion of the blade 8 when the blade 8 is sheared; one ends, far away from the fixed frame 1, of the upper tool rest 3 and the lower tool rest 2 are respectively provided with the sealing blocks 22 in an inclined mode, so that materials to be sheared, which slide along the blade 8, can be blocked by the sealing blocks 22 when moving to the openings of the upper tool rest 3 and the lower tool rest 2, the materials to be sheared are difficult to separate from the upper tool rest 3 and the lower tool rest 2, the possibility that shearing efficiency is influenced due to the fact that the materials to be sheared are hard and the materials to be sheared are separated from the upper tool rest 3 and the lower tool rest 2 along the blade 8 in a sliding.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
