DETAILED DESCRIPTION

[0017] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0018] A soil crushing device for traffic engineering construction, such as Figure 1-Figure 4 As shown, it includes a bracket 1, a jaw crusher 2, a feed frame 3, a discharge frame 4, a mounting frame 5, a first hydraulic rod 6, a buffer assembly and a hydraulic impact hammer 9. The top of the bracket 1 is fixedly connected to the jaw crusher 2, the left side of the jaw crusher 2 is fixedly connected to the feed frame 3, the bottom of the jaw crusher 2 is fixedly connected to the discharge frame 4, the right side of the jaw crusher 2 is fixedly connected to the mounting frame 5, the top of the mounting frame 5 is fixedly connected to two first hydraulic rods 6, a buffer assembly is connected between the piston rods of the first hydraulic rods 6, and the buffer assembly is connected to the hydraulic impact hammer 9. The hydraulic impact hammer 9 and the first hydraulic rod 6 are both inclined, and the side of the hydraulic impact hammer 9 close to the feed frame 3 is lower than the other side, and the side of the first hydraulic rod 6 close to the feed frame 3 is lower than the other side.

[0019] like Figure 1-Figure 3 As shown, the buffer assembly includes a mounting seat 7, a slider 8 and an elastic member 81. The mounting seat 7 is fixedly connected between the piston rod of the first hydraulic rod 6, the slider 8 is slidably connected inside the mounting seat 7, and the elastic member 81 is fixedly connected between the slider 8 and the mounting seat 7. The elastic member 81 is configured as a coil spring, and the slider 8 is fixedly connected to the hydraulic impact hammer 9.

[0020] When crushing the earth, the unloading end of the conveyor is higher than the support plate 12, and the earth is transported to the top of the support plate 12 by the conveyor, and the earth falls from the support plate 12 into the jaw crusher 2, and the earth is crushed by the jaw crusher 2, and the crushed earth falls out from the unloading frame 4. When large earth causes blockage between the jaw plates of the jaw crusher 2, the buffer assembly is driven by the first hydraulic rod 6 to move close to the jaw plates, so that the hydraulic impact hammer 9 moves close to the large earth, and the large earth is struck with high frequency by the hydraulic impact hammer 9, so as to directly crush large pieces of hard earth, stone-containing soil layers or concrete blocks, and quickly eliminate the blockage problem. The hydraulic impact hammer 9 can accurately act on the blockage. The blockage point is avoided, and the ineffective disturbance of the blocked earthwork by the traditional pushing or vibration method is avoided, the blockage processing efficiency is improved, and there is no need for manual intervention for cleaning, which reduces the safety risk of operators. After there is no blockage between the jaw plates, the hydraulic impact hammer 9 can be driven by the first hydraulic rod 6 to move in the opposite direction and reset. The first hydraulic rod 6 can retract the hydraulic impact hammer 9 when there is no blockage, so as to avoid occupying the space of the feed channel and ensure the normal feeding process. When the hydraulic impact hammer 9 is operating, the vibration of the hydraulic impact hammer 9 causes the slider 8 to slide in the mounting seat 7, and the elastic member 81 can play a buffering role, absorbing part of the reverse impact force of the hydraulic impact hammer 9, protecting the first hydraulic rod 6 from damage, and reducing the vibration of the crushing device.

[0021] like Figure 1 and Figure 4As shown, it also includes a support plate 12, a top block 13, a second hydraulic rod 14, a fixed block 15 and a wedge block 16. The support plate 12 and the second hydraulic rod 14 are fixedly connected to the bottom of the feed frame 3. Six top blocks 13 are slidably connected to the support plate 12. The top blocks 13 are connected to the wedge blocks 16 on one side close to the bottom of the feed frame 3. The side of the wedge blocks 16 close to the bottom of the feed frame 3 is set as an inclined surface. The left side of the wedge block 16 is larger than the right side. The piston rod of the second hydraulic rod 14 is fixedly connected to the fixed block 15. The fixed block 15 is slidably connected to the feed frame 3, and the wedge blocks 16 are in contact with the fixed block 15.

[0022] When material blockage occurs at the feed frame 3, the second hydraulic rod 14 drives the fixed block 15 to slide away from the jaw crusher 2, so that the fixed block 15 squeezes the left side of the inclined surface of the wedge block 16, and the wedge block 16 moves upward along the support plate 12, so that the top block 13 slides along the support plate 12 away from the inner bottom of the feed frame 3, thereby enabling the top block 13 to squeeze the earth blocking the material on the support plate 12, thereby releasing the earth blocking the material, further improving the material blockage processing efficiency of the crushing device; when the feed frame 3 is no longer blocked, the second hydraulic rod 14 drives the fixed block 15 to slide in the opposite direction and reset, so that the fixed block 15 is away from the left side of the inclined surface of the wedge block 16, and the wedge block 16 and the top block 13 are both moved in the opposite direction and reset.

[0023] like Figure 2 As shown, a visual detector 17 is also included. The front and rear sides of the inner wall of the mounting frame 5 are fixedly connected with the visual detector 17. The controllers of the first hydraulic rod 6, the second hydraulic rod 14 and the hydraulic impact hammer 9 are all connected to the visual detector 17 by signal. The visual detector 17 can detect the crushing device. When the jaw plates of the jaw crusher 2 are blocked, the visual detector 17 transmits the signal of the blocking to the controllers of the first hydraulic rod 6 and the hydraulic impact hammer 9, thereby starting the first hydraulic rod 6 and the hydraulic impact hammer 9 to process the blocked part. When the feed frame 3 is blocked, the visual detector 17 transmits the signal of the blocking to the controller of the second hydraulic rod 14, thereby starting the second hydraulic rod 14 to process the blocked part, thereby improving the blocking processing efficiency and automation of the crushing device.

[0024] like Figure 1 As shown, it also includes a water pipe 10 and a dry mist nozzle 11. The front and rear sides of the jaw crusher 2 are fixedly connected with the water pipe 10, and one end of the water pipe 10 is fixedly connected with the dry mist nozzle 11. The dry mist nozzle 11 is fixedly connected to the jaw crusher 2, and the other end of the water pipe 10 is connected to the water supply system. When crushing the earth, the dry mist nozzle 11 is used to spray the top of the jaw crusher 2, so as to reduce the dust generated by the jaw crusher 2 during crushing, and achieve the dust suppression effect. In addition, the dry mist nozzle 11 can make the water form micron-level water mist to absorb dust, so as to avoid agglomeration caused by excessive moisture in the earth.
