[0015] Furthermore, the side plate is fixed with a support rod, and the bottom surface of the support rod is in contact with the ground.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] I. This utility model, through the setting of a crusher shell, mounting groove, first gear, second gear, first crushing wheel, second crushing wheel, motor, and maintenance components, installs the first gear and second gear inside the mounting groove. When the motor starts, the motor drives the first gear to rotate, and the rotation of the first gear synchronously drives the rotation of the second gear, which in turn drives the first crushing wheel to rotate, and the second gear drives the second crushing wheel to rotate, thus crushing stones. Due to the obstruction of the crusher shell, stone particles cannot damage the drive structure. When maintenance is required, simply unscrew the nut from the outer surface of the bolt, and then pull the bolt out of the circular hole. At this time, the fixing rod retracts from the fixing block, and the mounting plate moves downward inside the movable groove, exposing the drive components inside the mounting groove for easy maintenance. Through reasonable mechanical connection and support structure, the first gear, second gear, first crushing wheel, and second crushing wheel can operate stably during operation, improving the overall performance and service life of the equipment, simplifying the maintenance process, and reducing downtime.

[0018] II. Based on the first beneficial effect, the crusher housing, mounting slot, first gear, second gear, first crushing wheel, second crushing wheel, motor, and protective components are designed so that when stones enter the crusher housing, they need to pass through baffles. The inclined groove on the top surface of the baffle guides the stones as they move downwards, compressing the springs within the limiting grooves. The springs simultaneously drive the baffles to move to both sides, allowing the stones to enter the crusher housing. When the stones stop falling, the springs quickly return to their original shape under the elastic force, causing the two baffles to move synchronously towards the center, blocking the feed inlet of the crusher housing and improving crushing safety. Through the synergistic effect of the baffles and springs, the feed inlet is quickly blocked after stones enter the crusher housing, effectively preventing accidental contact by operators or the entry of foreign objects, thus improving the safety of equipment operation.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0033] Please see Figures 1 to 5 As shown, this embodiment is a high-efficiency rock crushing device for mining engineering, comprising:

[0034] The crusher housing 11 and the mounting slot 12 are provided on one side of the crusher housing 11. A first gear 13 is installed inside the mounting slot 12. A second gear 14 meshes with one side of the first gear 13. A first crushing wheel 15 is fixedly connected to one side of the first gear 13. A second crushing wheel 16 is fixedly connected to one side of the second gear 14. A motor 17 is fixed to one side of the first gear 13. A mounting platform 18 is fixed to the lower surface of the motor 17. The lower end of the mounting platform 18 is fixed to the outer surface of the crusher housing 11.

[0035] The crusher housing 11 can withstand the high impact and vibration generated when crushing stones. The first gear 13 and the second gear 14 are the core transmission components in the crushing device. When the motor 17 starts, the first gear 13 is driven to rotate by the motor 17, and then the power is transmitted to the first crushing wheel 15 and the second crushing wheel 16 through the second gear 14 that meshes with it.

[0036] The maintenance assembly includes a movable groove 21, a mounting plate 22, a fixing rod 23, a connecting block 24, and a fixing block 25. The movable groove 21 is formed on the lower inner surface of the mounting groove 12. The mounting plate 22 is slidably installed inside the movable groove 21. The fixing rod 23 is L-shaped and fixed to the upper side of one side of the mounting plate 22. The connecting block 24 is fixed to the top of the fixing rod 23. The fixing block 25 is fixed to the center of one side of the crusher housing 11.

[0037] The movable groove 21 provides a sliding track for the mounting plate 22, allowing it to move downwards when needed to expose the internal drive components. The L-shaped fixing rod 23 is fixed to the upper side of the mounting plate 22, and its top connecting block 24 cooperates with the fixing block 25 to achieve fixation and stability of the mounting plate 22.

[0038] The outer surface of the mounting plate 22 has two straight slots 221, which correspond to the first gear 13 and the second gear 14. The outer surface of the fixing rod 23 has a fixing hole 231, and the outer surface of the fixing block 25 has a circular hole 251, which corresponds to the fixing hole 231. The fixing rod 23 passes through the fixing block 25, and a bolt 26 passes through the inside of the circular hole 251. A nut 27 passes through one side of the bolt 26.

[0039] The connecting block 24 and the fixing block 25 cooperate with each other and are secured by bolts 26 and nuts 27, ensuring the overall stability and reliability of the maintenance assembly. At the same time, they also facilitate quick disassembly and assembly when needed for equipment maintenance.

[0040] Working principle:

[0041] The first gear 13 and the second gear 14 are installed inside the mounting slot 12. When the motor 17 starts, the motor 17 drives the first gear 13 to rotate. The rotation of the first gear 13 synchronously drives the second gear 14 to rotate. The first gear 13 drives the first crushing wheel 15 to rotate, and the second gear 14 drives the second crushing wheel 16 to rotate, thus crushing the stones. Due to the obstruction of the crusher housing 11, the stone particles cannot damage the drive structure. When maintenance is required, simply unscrew the nut 27 from the outer surface of the bolt 26, and then pull the bolt 26 out of the circular hole 251. At this time, the fixing rod 23 is removed from the fixing block 25, and the mounting plate 22 moves downward inside the movable slot 21, exposing the drive components inside the mounting slot 12 for easy maintenance.

[0042] This step, through reasonable mechanical connections and support structures, ensures that the first gear 13, the second gear 14, the first crushing wheel 15, and the second crushing wheel 16 can operate stably during operation, improving the overall performance and service life of the equipment, simplifying the maintenance process, and reducing downtime.

[0043] Please see Figures 1 to 5 As shown; this embodiment, based on the above embodiment, further includes:

[0044] The protective assembly includes a side plate 31, a limiting groove 33, a spring 34, and a baffle 35. The side plate 31 is fixed to the upper ends of both sides of the crusher housing 11. The limiting groove 33 is opened on one side of the side plate 31 and passes through both sides of the crusher housing 11. The spring 34 is fixed inside the limiting groove 33. The baffle 35 is fixed to one end of the baffle 35, and the upper surface of the baffle 35 is provided with an inclined groove. The side plate 31 is fixed with a support rod 32, and the bottom surface of the support rod 32 is in contact with the ground.

[0045] The connection between the side plate 31 and the crusher housing 11 forms a sturdy frame, providing a mounting base for other components. The limiting groove 33 allows the spring 34 to move along a predetermined path when subjected to external force, thereby ensuring the smooth operation of the baffle 35. The spring 34 provides elasticity, enabling the baffle 35 to quickly return to its initial position after stones enter, blocking the feed inlet.

[0046] Working principle:

[0047] When the stones enter the crusher housing 11, they need to pass through the baffle 35. The inclined groove on the top surface of the baffle 35 guides the stones as they move downwards, compressing the spring 34 and causing it to compress inside the limiting groove 33. The spring 34 simultaneously drives the baffle 35 to move to both sides, allowing the stones to enter the crusher housing 11. When the stones stop falling, the spring 34 will quickly recover its deformation under the elastic force of the spring, causing the two baffles 35 to move synchronously towards the middle, blocking the feed inlet of the crusher housing 11 and improving the safety of crushing.

[0048] This step, through the synergistic action of baffle 35 and spring 34, ensures that the feed inlet is quickly blocked after the stone enters the crusher housing 11, effectively preventing accidental contact by operators or entry of foreign objects, and improving the safety of equipment operation.
