[0021] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0022] Example 1

[0023] This utility model is a device for crushing large ores into medium-sized ores, such as... Figure 1 As shown, it includes a horizontally arranged foundation 1, a support base 2 connected to one side of the upper surface of the foundation 1, a vertically downward-facing crushing mechanism connected to the lower surface of the top of the support base 2, an auxiliary crushing structure connected to the upper surface of the foundation 1, the auxiliary crushing structure being located below the crushing mechanism, the crushing end of the crushing mechanism abutting against the auxiliary crushing structure during its downward movement, a pushing mechanism on one side of the auxiliary crushing structure, and a discharging structure on the other side of the auxiliary crushing structure, during the operation of the pushing mechanism, the pushing end enters the interior of the auxiliary crushing structure and drives the discharging structure to open the discharge port.

[0024] The specific implementation method of this embodiment is as follows: When it is necessary to crush large ore, the pusher mechanism is reset by starting the pusher mechanism, so that the pusher mechanism is in the contraction stage. At this time, the front end of the pusher mechanism is used to close one end of the auxiliary crushing structure. At the same time, the discharge structure is also in the reset stage, so that the discharge structure closes the other end of the auxiliary crushing structure. Then, the crushing mechanism is in the contraction stage. At this time, the large ore to be crushed is put into the interior of the auxiliary crushing structure, and the crushing mechanism is started to move downward. Through the cooperation between the crushing mechanism and the auxiliary crushing structure, the large ore is squeezed and finally crushed. After the large ore is crushed, the crushing mechanism is started to move upward and leave the auxiliary crushing structure. The pusher mechanism is started to move and push out the crushed ore blocks inside the auxiliary crushing structure until the discharge port of the discharge structure is opened, so that the ore blocks inside the auxiliary crushing structure are completely pushed out.

[0025] Preferably, the auxiliary crushing structure is rectangular in shape, which facilitates the pushing mechanism to push away the ore blocks inside the auxiliary crushing structure.

[0026] Preferably, before hydraulic crushing, workers use steel hammers to crush large ore into medium-to-large ore blocks, which are then placed inside the auxiliary crushing structure to facilitate the crushing mechanism to compress and crush the medium-to-large ore.

One end of the oil supply pump 7 is connected to one of the oil supply pipes 6, and the other end of the oil supply pipe 6 is connected to the lower end of the hydraulic cylinder body 3. The other end of the oil supply pump 7 is connected to another oil supply pipe 6, and the other end of the oil supply pipe 6 is connected to the upper end of the hydraulic cylinder body 3.

[0030] The specific implementation method of this embodiment is as follows: the support base is used to connect the hydraulic cylinder body, and at the same time, the hydraulic cylinder body is set vertically. The oil supply pump delivers hydraulic oil to the inside of the hydraulic cylinder body, so that the hydraulic cylinder body can drive the telescopic shaft to extend or retract. Preferably, when the oil supply pump delivers hydraulic oil to the lower end of the hydraulic cylinder body through one of the oil supply pipes, it drives the telescopic shaft to move upward, and then causes the telescopic shaft to retract along the hydraulic cylinder body. When the oil supply pump delivers hydraulic oil to the upper end of the hydraulic cylinder body through the other oil supply pipe, it drives the telescopic shaft to move downward, and then causes the telescopic shaft to move downward along the hydraulic cylinder body. Finally, it drives the breaker hammer to contact the ore inside the crushing tank, and the breaker hammer crushes the ore.
