[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1

[0030] Referring to Figure 1-2, a crushing device includes a base plate, a connecting frame fixed to the top of the base plate, two support frames fixed to one end of the connecting frame, a first fixed motor fixed to the top of the two support frames, a pulley fixed to the output end of the first fixed motor, an eccentric shaft rotatably connected to the inner side of the top of the connecting frame, a flywheel fixed to one side of the outer side of the eccentric shaft, a counterweight wheel fixed to the other side of the outer side of the eccentric shaft, the pulley and the flywheel being connected by belt drive, a movable jaw plate fixed to the outer side of the eccentric shaft, a fixed jaw plate fixed to one end of the inner side of the connecting frame, and a pressing mechanism provided at the end of the top of the connecting frame near the fixed jaw plate.

[0031] The pressing mechanism includes a fixed plate, a sliding rod, a connecting plate, a fixed rod, and a pressing plate. A fixed plate is fixed to one side of the top end of the connecting frame. A sliding rod is slidably connected to the inner side of the fixed plate. A connecting plate is fixed to one side of the sliding rod. A fixed rod is fixed to one side of the connecting plate. A buffer mechanism is provided at the bottom of the fixed rod. A pressing plate is fixed to the bottom of the buffer mechanism.

[0032] The pressing mechanism also includes a second fixed motor, a transmission rod, a gear and a rack. The second fixed motor is fixed to one side of the top of the fixed plate. The output end of the second fixed motor is fixed to the transmission rod. The transmission rod is rotatably connected to the fixed plate. The gear is fixedly connected to the outside of the transmission rod. The rack is fixedly connected to the outside of the sliding rod. The rack is meshed with the gear.

[0033] The pressing mechanism can apply concentrated vertical downward pressure to large rocks, which, together with the squeezing force of the moving jaw plate and the fixed jaw plate, forms a three-dimensional crushing force field.

[0034] Example 2

[0035] Referring to Figure 1-2, a crushing device includes a buffer mechanism comprising a sliding groove, a sliding plate, a spring, a connecting rod, and a damper. A sliding groove is provided on the inner side of the bottom end of the fixed rod, and a sliding plate is slidably connected to the inner side of the bottom end of the sliding groove. A spring is fixed to the top of the sliding plate, and the top of the spring is fixedly connected to the fixed rod. A connecting rod is fixed to the bottom of the sliding plate, and the connecting rod is slidably connected to the fixed rod. The bottom of the connecting rod is fixedly connected to the pressing plate. Multiple dampers are evenly distributed and fixed on the outer side of the bottom end of the fixed rod, and the telescopic ends of the dampers are fixedly connected to the sliding plate.

[0036] The buffer mechanism can absorb and disperse the reverse impact force generated when rocks break, preventing the connecting parts from directly bearing rigid impact.

[0037] The sliding plate profile consists of four arms, similar to rounded rectangles, extending symmetrically from the center outwards. The ends of each arm and the arms between them are rounded.

[0038] A circular limiting plate is fixed to the bottom of the sliding rod. The limiting plate is located inside the fixed plate. The design of the limiting plate can prevent the sliding rod from moving out of the inner side of the fixed plate.

[0039] The crushing device provided by this utility model is used as follows: When the first fixed motor is started, the movable jaw plate, which is fixedly connected to the eccentric shaft, is moved by the belt driven by the pulley and flywheel. The movable jaw plate and the fixed jaw plate cooperate to crush the boulder.

[0040] To increase the crushing speed of the boulder during crushing, a second fixed motor is controlled in real time to drive the transmission rod to rotate. This causes the gear fixedly connected to the transmission rod to rotate as well. Since the gear meshes with the rack, the rotation of the gear drives the rack to move, which in turn causes the sliding rod fixedly connected to the rack to move as well. Since the sliding rod is fixedly connected to the connecting plate, and the connecting plate is fixedly connected to the fixed rod, the fixed rod drives the pressing plate to press the boulder. The pressing mechanism can apply concentrated vertical downward pressure to the large rock, which, together with the squeezing force of the moving jaw plate and the fixed jaw plate, forms a three-dimensional crushing force field.

[0041] When breaking large rocks, the moment the rocks break, a huge reverse impact force is generated. The impact force drives the pressing plate to move, which in turn causes the connecting rod, which is fixedly connected to the pressing plate, to move as well. This causes the sliding plate, which is fixedly connected to the connecting rod, to move as well. As a result, the sliding plate compresses the spring, and the impact force is dispersed and consumed through multiple dampers fixedly connected to the sliding plate.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
