Technical Field

[0001] The utility model relates to the technical field of hydraulic crushing equipment, in particular to a four-column hydraulic crusher with a protective structure. Background Art

[0002] Hydraulic crusher is a highly efficient crushing equipment, widely used in various industrial fields, such as mining, building materials, metallurgy, etc. It mainly drives the breaker hammer through hydraulic power to crush various hard materials.

[0003] When working, the hydraulic breaker will input oil into the breaker hammer, so that it can accumulate energy and then quickly impact the material, thereby achieving crushing. For example, the Chinese utility model patent disclosed by publication number CN211587009U is a magnesia sintered block hydraulic crusher. The application includes two sets of legs, two sets of guide columns, an upper plate, a hydraulic device, two sets of connecting columns, connecting flanges, bolts, pressure blocks and tops. The tops of the two sets of legs are respectively connected to the bottom ends of the two sets of guide columns, the tops of the two sets of guide columns are respectively connected to the bottom ends of the upper plate, and the bottom ends of the two sets of connecting columns are respectively connected. The ends are respectively connected to the top of the upper plate, and the bottom end of the hydraulic device is connected to the top of the upper plate, which can transport the magnesia sintered block to between the two sets of legs, avoiding the danger of human hands touching the top and improving the operation safety. However, when the magnesia sintered block is crushed by the top, the pad and the pressure block are open. Therefore, when the top crushes the magnesia sintered block, some of the crushed magnesia sintered block fragments will splash around due to the crushing pressure, thereby causing damage to surrounding equipment and personnel.

[0027] A plurality of T-shaped mounting grooves 11 are provided at the bottom of the punch 6 . The plurality of T-shaped mounting grooves 11 provided at the bottom of the punch 6 can provide basic conditions for the installation of the crushing cone 7 and the connecting plate 9 .

[0028] like Figure 2 、 Figure 5 As shown, the crushing cone 7 also includes a first cone 12 and a second cone 13. An insert block 15 is fixedly installed on one side of the first cone 12, and a slot 16 of the same shape as the insert block 15 is opened on the side of the second cone 13 relative to the first cone 12, and the first cone 12 and the second cone 13 are connected to each other through the insert block 15 and the slot 16. Two first T-shaped mounting seats 14 are fixedly installed on the top of the first cone 12, and two first T-shaped mounting seats 14 are also fixedly installed on the top of the second cone 13. The first cone 12 and the second cone 13 are respectively installed on the bottom of the punch 6 through the first T-shaped mounting seats 14 on the top, and the first T-shaped mounting seats 14 are installed on one side of the corresponding T-shaped mounting groove 11. The first cone 12 and the second cone 13 are connected to each other through the insert block 15 and the slot 16, which can improve the stability of the connection between the first cone 12 and the second cone 13, and enable the first cone 12 and the second cone 13 to be quickly installed on the bottom of the punch 6 through the first T-shaped mounting seats 14.

[0029] like Figure 2-Figure 4 、 Figure 6As shown, a plurality of slide grooves 17 are provided on one side of the connecting plate 9, and a plurality of second T-shaped mounting seats 18 are fixedly installed on the other side of the connecting plate 9.

At this time, the punch 6 continues to drive the crushing cone 7 to move downward, and the punch 6 simultaneously drives the connecting plates 9 on both sides to move downward synchronously, and The multiple slide grooves 17 on one side of the two connecting plates 9 slide on the guide rails 20 on the corresponding side of the protective cover 8, so that the two protective covers 8 can continue to cover the magnesia sintered ore while ensuring the normal downward movement of the punch 6. Then, the punch 6 pressure-crushes the magnesia sintered block on the base 1 through the crushing cone 7 at the bottom. When the magnesia sintered block is crushed, the output end of the hydraulic mechanism 4 drives the slide 5 to move upward, so that the slide 5 drives the punch 6 to move upward, and the connecting plates 9 on both sides of the punch 6 slide up on the corresponding guide rails 20 through the slide grooves 17 on one side, and make one side of the connecting plate 9 contact the top side of the protective cover 8, driving the protective cover 8 to move up and separate from the base 1.
