Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in Figures 1-3, the present invention provides a technical solution: a hydraulic crusher with a telescopic arm, comprising a base 7, the upper end of the base 7 is fixed with a first support arm 8, and the upper right of the first support arm 8 A second support arm 2 is provided, a crushing frame 6 is provided at the lower right of the second support arm 2, a mounting frame 3 is fixed on the upper ends of the first support arm 8 and the second support arm 2, and the installation on the first support arm 8 The first hydraulic cylinder 1 is fixed on the frame 3, the second hydraulic cylinder 4 is fixed on the mounting frame 3 on the second arm 2, the front and rear ends of the first support arm 8 are provided with mounting seats 12, and the outer side of the mounting seat 12 is provided. A telescopic box 9 is fixed, and a telescopic hole 15 is opened inside the telescopic box 9, and a telescopic rod 14 is arranged inside the telescopic hole 15. Rotary frame 13.

The front and rear sides of the end of the second support arm 2 are provided with a sliding frame 5 . The sliding frame 5 makes the fixing of the crushing frame 6 more stable, and the sliding frame 5 is movably connected with the second support arm 2 .

The upper right of the crushing frame 6 is provided with a movable plate 18. The movable plate 18 rotates on the sliding frame 5, which can make the movement of the crushing frame 6 more flexible. The lower end of the movable plate 18 is movably connected with the upper end of the crushing frame 6. The upper end of 18 is movably connected with the right end of the sliding frame 5 .

The piston end of the first hydraulic cylinder 1 is fixedly connected with the second support arm 2 , through the operation of the first hydraulic cylinder 1, the distance between the first support arm 8 and the second support arm 2 is lengthened, and the piston of the second hydraulic cylinder 4 is extended. The end is fixedly connected with the sliding frame 5 .

The telescopic rods 14 are respectively fixedly connected with the corresponding rotating frames 13. The mounting seat 12 is provided with a mounting hole 11, and the mounting hole 11 is provided with a bolt 10. When the mounting seat 12 needs to be disassembled from the first support arm 8, The mounting seat 12 can be disassembled by directly screwing out the bolts 10 on the mounting seat 12 , and the mounting seat 12 is mounted on the first support arm 8 through the bolts 10 .

One end of the rotating frame 13 corresponding to the second arm 2 is fixed with a rotating rod 16, and the rotating frame 13 is directly sleeved on the rotating rod 16. Therefore, the rotating frame 13 can be directly taken out from the rotating rod 16. One end corresponding to the second support arm 2 is provided with a bearing 17. By rotating the bearing 17 on the rod 16, when the second support arm 2 is moving, the telescopic rod 14 will be pulled to move in the telescopic box 9, thereby making the second support arm 2 move. The arm 2 rotates on the rotating rod 16 , so the bearing 17 avoids friction between the second supporting arm 2 and the rotating rod 16 , and the rotating rod 16 is movably connected with the second supporting arm 2 through the bearing 17 .

Working principle: When the present invention is in use, when the first arm 8 and the second arm 2 of the hydraulic breaker need to be telescopic, by controlling the first hydraulic cylinder 1 to work, the piston end of the first hydraulic cylinder 1 starts to push the second arm. The support arm 2 moves forward. Since the connection between the second support arm 2 and the first support arm 8 is through the telescopic box 9 and the rotating frame 13, after the position of the second support arm 2 moves, the first support arm The distance between 8 and the second arm 2 will become longer, and the movement of the second arm 2 will drive the movement of the rotating frame 13. Since the rotating frame 13 and the end face of the telescopic rod 14 are fixed together, the rotating frame 13 will Pull the telescopic rod 14 out of the telescopic hole 15 in the telescopic box 9, and through the bearing 17 between the rotating rod 16 and the second support arm 2, the second support arm 2 can be rotated on the rotating rod 16. When the telescopic box 9 is disassembled, the bolts 10 on the mounting base 12 are unscrewed, and then the rotating frame 13 is taken out from the rotating rod 16 , and the mounting base 12 on the telescopic box 9 can be disassembled from the first support arm 8 .
