[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A hydraulic crusher for excavators. It includes a crusher body 1. A fixed jaw 2 is fixedly mounted on the crusher body 1. A crushing jaw 3 is rotatably mounted on the crusher body 1. Specifically, a second rotating shaft 7 is rotatably mounted on the crusher body 1, and the second rotating shaft 7 is fixedly connected to the crushing jaw 3.

[0026] The crushing jaw 3 cooperates with the fixed jaw 2. The crushing jaw 3 and the fixed jaw 2 work together to crush the object.

[0027] A first drive assembly for driving the shredder 3 to rotate is installed between the shredder 3 and the shredder body 1.

[0028] Specifically, the first driving component is configured as two groups, and the two groups of driving components are arranged horizontally along the front-back direction.

[0029] The first drive assembly includes: a first rotating shaft 4, a hydraulic rod 5, and a fixing block 6.

[0030] There are two first rotating shafts 4. The two first rotating shafts 4 are arranged in parallel. One first rotating shaft 4 is fixedly installed on the crushing pliers body 1, and the other first rotating shaft 4 is fixedly installed on the crushing jaw 3.

[0031] Two fixing blocks 6 are provided, each corresponding to one of the first rotating shafts 4. The two fixing blocks 6 are respectively rotatably mounted on their respective first rotating shafts 4.

[0032] The hydraulic rod 5 is fixedly installed between two fixed blocks 6. The axis of the telescopic shaft of the hydraulic rod 5 is perpendicular to the axis of the first rotating shaft 4.

[0033] When the hydraulic rod 5 is activated and extended, it pushes the crushing jaw 3 to rotate closer to the fixed jaw 2. This allows the crushing jaw 3 and the fixed jaw 2 to crush the object together. When the hydraulic rod 5 retracts, it drives the crushing jaw 3 to rotate away from the fixed jaw 2, ejecting the crushed object and preparing it for the next crushing operation.

[0034] A fixed housing 18 is fixedly installed on the shredder body 1. A water storage airbag 15 is installed inside the fixed housing 18. A water inlet pipe 17 is connected to the bottom of the water storage airbag 15. A water outlet pipe 16 is installed on the shredder body 1 between the fixed jaw 2 and the shredder jaw 3. The water outlet pipe 16 is connected to the water storage airbag 15.

[0035] When crushing objects, the water outlet pipe 16 sprays water between the fixed jaw 2 and the crushing jaw 3 to eliminate dust.

[0036] A first extrusion plate 12 is horizontally slidably installed inside the fixed box 18. The first extrusion plate 12 is located on one side of the water storage airbag 15. A second drive assembly for driving the first extrusion plate 12 to move horizontally is installed between the crushing jaw 3 and the first extrusion plate 12.

[0037] Specifically, the second drive assembly includes: a connecting block 11, a first connecting rod 8, and a second connecting rod 9.

[0038] Wherein: the connecting block 11 is fixedly installed on the top of the first extrusion plate 12. A sliding groove is formed on the upper end face of the fixed box 18. The connecting block 11 is located outside the fixed box 18 and is slidably connected to the sliding groove.

[0039] The first connecting rod 8 is fixedly connected to the second rotating shaft 7.

[0040] A third rotating shaft 10, whose axis is parallel to the axis of the first rotating shaft 4, is fixedly installed on the connecting block 11. The second connecting rod 9 is rotatably mounted on the first connecting rod 8, and the other end of the second connecting rod 9 is hinged to the end of the first connecting rod 8 away from the second rotating shaft 7.

[0041] When the crushing jaw 3 rotates towards the side closer to the fixed jaw 2, it drives the second rotating shaft 7 to rotate. The rotation of the second rotating shaft 7 drives the first connecting rod 8 to rotate. The first connecting rod 8, via the second connecting rod 9, pulls the connecting block 11 towards the side closer to the water storage air bladder 15. This causes the second extrusion plate 14 to extrude pressure on the water storage air bladder 15, and water from the water outlet pipe 16 is sprayed out to moisten the area between the fixed jaw 2 and the crushing jaw 3.

[0042] Furthermore, a second extrusion plate 14 is fixedly installed on the side of the water-storing airbag 15 near the first extrusion plate 12. A plurality of springs 13 are evenly distributed and fixedly installed between the second extrusion plate 14 and the first extrusion plate 12. One end of each spring 13 is fixedly connected to the first extrusion plate 12, and the other end of each spring 13 is fixedly connected to the second extrusion plate 14.

[0043] When the first extrusion plate 12 moves closer to the water storage air bladder 15, it first compresses the spring 13. The spring 13 then drives the second extrusion plate 14 to move closer to the water storage air bladder 15. The movement of the second extrusion plate 14 compresses the water storage air bladder 15, increasing the pressure inside and opening the one-way valve on the water outlet pipe 16. Water from the water storage air bladder 15 is then sprayed through the water outlet pipe 16 between the fixed jaw 2 and the crushing jaw 3. When the first extrusion plate 12 can no longer move, the spring 13 between the first extrusion plate 12 and the second extrusion plate 14 will release, allowing the second extrusion plate 14 to continue compressing the water storage air bladder 15. This ensures that water can still be sprayed from the water outlet pipe 16 during the crushing process, extending the spraying time.

[0044] The specific usage method of this application is as follows:

[0045] When the stairs are being crushed, the hydraulic rod 5 is activated, causing it to extend. The extension of the hydraulic rod 5 pushes the crushing jaw 3 to rotate around the second rotating shaft 7 via the fixed block 6 and the first rotating shaft 4, causing the crushing jaw 3 to move closer to the fixed jaw 2.

[0046] Please see the appendix Figure 3 When the crushing jaw 3 rotates, it drives the second rotating shaft 7 to rotate. The second rotating shaft 7 drives the first connecting rod 8 to rotate upward. The first connecting rod 8, through the second connecting rod 9, pulls the connecting block 11 to move to the right on the fixed box 18.

[0047] When the connecting block 11 moves, it will drive the first extrusion plate 12 to move simultaneously. The first extrusion plate 12 pushes the second extrusion plate 14 to move through the spring 13. The second extrusion plate 14 will squeeze the water storage air bag 15. At this time, the one-way valve on the water outlet pipe 16 will open, and the water inside the water storage air bag 15 will be sprayed out through the water outlet pipe 16. Before the crushing jaw 3 rotates and contacts the building body, the water outlet pipe 16 sprays water to wet the position of the crushing clamp body 1, thereby reducing the generation of dust during crushing.

[0048] As the first extrusion plate 12 moves towards the water storage bladder 15, it first compresses the spring 13. The spring 13 then drives the second extrusion plate 14 to move towards the water storage bladder 15. The movement of the second extrusion plate 14 compresses the water storage bladder 15, increasing the pressure inside and opening the one-way valve on the water outlet pipe 16. Water from the water storage bladder 15 is then sprayed through the water outlet pipe 16 between the fixed jaw 2 and the crushing jaw 3. When the first extrusion plate 12 can no longer move, the spring 13 between the first and second extrusion plates 12 and 14 keeps the second extrusion plate 14 in a state of compression over the water storage bladder 15. This ensures that water can still be sprayed from the water outlet pipe 16 during the crushing process, extending the spraying time.

[0049] When the hydraulic rod 5 retracts to reset the crushing jaw 3, the first connecting rod 8 pushes the connecting block 11 and the first extrusion plate 12 to the left via the second connecting rod 9. When the first extrusion plate 12 moves to the left, the spring 13 will reset first. At this time, the spring 13 will still extrude water through the second extrusion plate 14 to squeeze the water storage airbag 15 to spray water and remove dust from the crushing area.

[0050] After the spring 13 is reset, it will pull the second compression plate 14 to reset and stop squeezing the water storage air bag 15. When the second compression plate 14 is reset, it will pull one side of the water storage air bag 15 to move. At this time, the one-way valve on the water outlet pipe 16 is closed, and the one-way valve on the water inlet pipe 17 is opened to draw water into the water storage air bag 15 from the outside.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
