Description

Technical Field

[0001] The present invention relates to the technical field of breaking hammers, and in particular to a composite working mechanism of an excavator. Background Art

[0002] Hydraulic breaker is a commonly used operating mechanism of excavators. The power source of the hydraulic breaker is the pressure oil provided by the pump station of the excavator or loader. It can more effectively clean floating stones and soil in rock crevices when excavating the foundation of a building.

[0003] The prior art discloses a variety of excavator breakers, for example, a prior art excavator breaker with publication number CN115787429A, which is equipped with a bracket at the bottom of a cylinder body and a roller at the bottom of the bracket. When breaking the road surface, after the cylinder body and the excavator arm are installed together, the excavator can be used to push the movement of the entire bracket, and during the movement, the drill rod at the bottom of the cylinder body continuously breaks the road surface, thereby breaking the road surface while walking, and the breaking operation efficiency is high; another example is a prior art excavator breaker hammer structure for road construction with publication number CN116950173B, which is equipped with a negative pressure chamber, a linkage chamber and the connecting pipelines therebetween, and in the process of using hydraulic oil to drive the piston rod thereon to move upward, a negative pressure can be formed at the top of the inner cavity of the negative pressure chamber, and the hydraulic oil in the inner cavity of the cylinder structure can be absorbed and extracted, and then when the piston rod moves downward, the energy consumption generated during the extrusion and transportation can be effectively reduced.

[0004] The existing excavator operating hammer mechanism generally only has a telescopic hammer rod as a working part, which can only perform local crushing of the target by point tapping, and does not have a tearing and crushing effect on the target. The operating effect is relatively simple. When hitting the target, the end of the hammer rod is always directly pressed on the target. The displacement of the hammer rod when hitting the target is insufficient, resulting in a low impact force on the target. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a composite working mechanism for an excavator to solve the problems mentioned in the above background technology.

[0006] The composite working mechanism of an excavator of the present invention comprises a shell body, a connecting part and a hammer rod mechanism, wherein the connecting part is installed at the upper part of the shell body, the connecting part is connected to the excavator arm, the hammer rod mechanism is installed in the shell body, and the hammer rod of the hammer rod mechanism extends out from the bottom of the shell body; the composite working mechanism of the ... rotating plate, a roller, a mounting plate and a plurality of crushing claws, the hammer rod is divided into an upper part and a lower part, the upper part and the lower part are rotatably connected, a locking structure is arranged between the upper part and the lower part, the rotating plate is rotatably or lockably installed at the lower end of the shell body, the rotating plate is sleeved on the outer side of the hammer rod of the hammer rod mechanism, and a locking structure is arranged on the side wall of the rotating plate A plurality of inclined chutes are arranged, a plurality of rollers are rotatably installed at the lower part of the hammer rod of the hammer rod mechanism, a plurality of rollers roll in a plurality of chutes of the turntable respectively, a mounting plate is installed at the lower end of the turntable, and a plurality of crushing claws are installed at the lower end surface of the mounting plate; when working, the connecting part is connected with the excavator arm, the hammer rod mechanism is connected with the hydraulic oil pipe of the excavator, and different working modes of the compound working mechanism of the excavator are selected according to the specific construction requirements of the operation target: mode 1, the lower part of the hammer rod with a larger length is selected to be fixedly connected with the upper part of the hammer rod, and a plurality of crushing claws are removed. At this time, the compound working mechanism of the excavator The first working mechanism is a conventional working mode, that is, only the hammer rod is used to perform point-knocking and crushing operations on the local part of the target; mode two, the lower part of the hammer rod with a smaller length is selected to be rotatably connected with the upper part of the hammer rod, so that when the hammer rod is retracted, its lower end can be stored inside the multiple crushing claws. When the excavator's composite working mechanism is working, the ends of the multiple crushing claws are pressed against the target, and the hammer rod is separated from the target when it is retracted. When the hammer rod is extended to strike the target, the stroke is longer, thereby having a greater impact force on the target and improving the point crushing effect on the target; mode three, the lower part of the hammer rod with a smaller length is selected to be fixed to the upper part of the hammer rod The hammer rod is connected so that when it is extended, its lower end is still stored inside the multiple crushing claws. When the excavator composite working mechanism is working, the ends of the multiple crushing claws are pressed against the target, and the hammer rod does not directly hit the target when it reciprocates and retracts. When the hammer rod reciprocates and retracts, the multiple rollers on the lower part of the hammer rod move back and forth synchronously, and the multiple rollers and the multiple slide grooves of the turntable are squeezed and matched with each other, thereby driving the turntable, the mounting plate and the multiple crushing claws to reciprocate, so that the tips of the multiple crushing claws rotate and dig the target, and the multiple crushing claws push away the fragments of the target, thereby improving the crushing efficiency of the target.Mode 4: Select a longer lower part of the hammer rod and fix it to the upper part of the hammer rod, so that the hammer rod extends out from under the multiple crushing claws when extended, and is stored inside the multiple crushing claws when contracted. When the excavator's compound operating mechanism is in operation, the excavator's boom moves to press the ends of the multiple crushing claws onto the target to be crushed. At this time, the hammer rod of the hammer rod mechanism is stored inside the multiple crushing claws, and a certain gap is set between the end of the hammer rod of the hammer rod mechanism and the target.

Then, when performing external crushing operation on the target, different working modes of the excavator composite working mechanism are selected according to the specific construction requirements of the operation target: mode one, mode two, mode three or mode four; then, when crushing the target from the inside to the outside, when pulling the wall inward, the vertical rod 15 is adjusted to the right position and then stopped, and the vertical rod 15 and the hook rod 16 are extended into the inside of the target through the window or hole of the target, so that the hook rod 16 hooks the target from the inside, and the excavator boom is retracted so that the hook rod 16 pulls the target down or crushes it from the inside to the outside; finally, when the target needs to be hooked and crushed from the inside to the outside, the vertical rod 15 and the hook rod 16 are extended to the inside of the target, and the hook rod 16 is ... The hook rod 16 is hooked on the inner side of the target, and the hammer rod mechanism 3 is in operation. When the hammer rod of the hammer rod mechanism 3 reciprocates and retracts, the push block 30 is driven to reciprocate. The push block 30 pushes the pushing rack 28 up and down through the connecting block 29. When the pushing rack 28 moves upward, the helical teeth four and three of the pushing rack 28 cooperate to push the limiting tooth block 26 upward. The two limiting tooth blocks 23 are meshed and fixed with the two limiting racks 25. When the pushing rack 28 moves downward, the helical teeth four of the pushing rack 28 and the helical teeth three of the limiting tooth block 26 slide relative to each other, so that the vertical rod 15 will not drop, so that the vertical rod 15 and the hook rod 16 gradually move toward the crushing claw 7 when the hammer rod mechanism 3 works, so that the hook rod 16 continues to apply pressure to the target from the inside to the outside, thereby hooking and crushing the inside of the target.

[0044] The main functions achieved by the present invention are:

[0045] 1. It can realize multiple working modes and thus achieve a variety of different crushing effects, with good practicality;

[0046] 2. The direction and angle of the hammer rod and multiple crushing claws 7 can be adjusted to crush the target at different angles;
