Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1-5 shown, a gravel device for a water conservancy project includes a crushing box 1. One side surface of the crushing box 1 is fixedly connected with a protective shell 2. A motor 3 is fixedly connected inside the protective shell 2. The output shaft of the motor 3 is fixedly connected with a gear 4. A crushing wheel 5 is fixedly installed at a position near the middle inside the crushing box 1. The top end of the crushing box 1 is fixedly connected with a feed inlet 6. A rotating shaft 7 is fixedly connected at a position near the top end inside the crushing box 1. A baffle 8 is sleeved on the surface of the rotating shaft 7. A discharge platform 11 is fixedly connected at a position near the bottom end inside the crushing box 1. A discharge port 12 is opened at a position near the bottom end of the front end of the crushing box 1. A buffer structure 9 is arranged between the inside of the crushing box 1 and the bottom end of the baffle 8;

[0025] The buffer structure 9 includes fixed seats 901. There are two fixed seats 901. The fixed seats 901 are respectively located at the position where the bottom end of the baffle 8 is close to the crushing box 1 and the position where the inner surface of the crushing box 1 is close to the crushing wheel 5. Buffer columns 902 are rotatably connected inside both fixed seats 901. An activity groove 903 is opened at one end of the buffer column 902 far away from the fixed seat 901. A spring 904 is fixedly connected inside the activity groove 903. One end of the spring 904 far away from the fixed seat 901 is fixedly connected with a connecting rod 905.

[0026] In this embodiment, there are two crushing wheels 5. Crushing rollers are arranged at the central positions of the two crushing wheels 5. The crushing rollers penetrate through one side of the crushing box 1 and are fixedly connected with the gear 4. The two gears 4 are meshed with each other.

[0027] The motor 3 drives the gear 4 to rotate, and the gears 4 mesh with each other so that the two gears 4 can rotate in opposite directions, thereby driving the two crushing wheels 5 to rotate in opposite directions through the crushing roller, thereby playing the role of crushing stones.

[0028] In this embodiment, cross bars are provided on the surface of the connecting rod 905 near both ends, and the connecting rod 905 is movably connected to the movable groove 903 .

[0029] The connecting rod 905 can move along the movable groove 903, and the cross bar plays a limiting role, so that the connecting rod 905 will not escape from the movable groove 903, and the moving distance of the connecting rod 905 is limited, so that the rotation path of the baffle 8 is limited, thereby enhancing the working stability of the stone crushing device.

[0030] In this embodiment, the fixing seat 901 is in an “H” shape, the discharging platform 11 is a horizontal plate with a certain inclination angle, and the discharging platform 11 and the discharging port 12 are fixedly connected.

[0031] The "H"-shaped fixing seat 901 ensures that the buffer column 902 will not separate from the fixing seat 901 and will only rotate along the cross bar of the fixing seat 901. Since the discharge platform 11 has a certain inclination angle, the crushed stones are discharged along the discharge port 12 under the action of gravity.

[0032] In this embodiment, a limiting structure 10 is arranged between the other side surface of the crushing box 1 and the baffle 8, and the limiting structure 10 includes a limiting plate 1001, and the limiting plate 1001 is located at the other side surface of the crushing box 1 near the top position, and both side surfaces of the crushing box 1 are provided with movable grooves 1003, and movable rods 1002 are fixedly connected to the positions near the movable grooves 1003 on both sides of the baffle 8, and a screw 1004 is threadedly connected to the center position of the upper end surface of the limiting plate 1001, and a driven bevel gear 1005 is fixedly connected to the bottom end of the screw 1004, and the driven bevel gear 1005 is meshedly connected with the active bevel gear 1006, and the active bevel gear 1006 is fixedly connected with a handwheel 1007 on the side away from the crushing box 1, and both ends of the limiting plate 1001 are movably connected with movable columns 1008, and the two movable columns 1008 are provided with openings on the side surface near the screw 1004, and a movable rod 1009 is fixedly connected in the opening.

[0033] The limiting structure 10 allows the minimum opening angle between the two baffles 8 to be adjusted, so that smaller and lighter stones can also enter the crushing box 1 to be crushed, thereby enhancing the applicability of the stone crushing device.

[0034] In this embodiment, the screw 1004 is movably connected to the crushing box 1, and the contact surface between the screw 1004 and the crushing box 1 is in a "T" shape. The upper end surface of the limit plate 1001 is movably connected to the movable rod 1009 at both ends, and the movable column 1008 is fixedly connected to the crushing box 1.

[0035] The "T"-shaped contact surface limits the screw rod 1004 and allows it to rotate without restriction. The limiting plate 1001 can move along the movable rod 1009, enhancing the stability of the limiting plate 1001 during movement.

[0036] In this embodiment, the moving groove 1003 is arc-shaped and coincides with the rotation trajectories of the baffle 8 and the moving rod 1002. One end of the moving rod 1002 close to the limiting plate 1001 is "T"-shaped.

[0037] The moving groove 1003 does not block the rotation of the moving rod 1002. When the baffle 8 works, the moving rod 1002 will move back and forth along the moving groove 1003. The "T"-shaped moving rod 1002 makes the limiting of the moving rod 1002 by the limiting plate 1001 more stable and facilitates the manual adjustment of the moving rod 1002, enhancing the applicability of the device.

[0038] It should be noted that the present utility model is a gravel device for water conservancy projects. When in use, the motor 3 is started to drive the gear 4 to rotate. Since the two gears 4 mesh with each other, the two gears 4 rotate relative to each other, driving the two crushing wheels 5 to rotate towards each other, performing the function of crushing stones.

[0039] The stones are put into the crushing box 1 through the feeding port 6. The stones will first impact the baffle 8, causing the connecting rod 905 to compress the spring 904. Then the connecting rod 905 will move along the moving groove 903, causing the baffle 8 to rotate along the rotating shaft 7. As a result, the stones enter the interior of the crushing box 1 along the baffle 8 and come into contact with the crushing wheels 5 to be crushed. Due to the resilience of the spring 904 and the limiting effect of the moving groove 903, the baffle 8 will rebound to its original position and continue to play a buffering role. Due to the baffle 8 and the buffering structure 9, the impact force of the stones is weakened, preventing the stones from directly impacting the crushing wheels 5 and reducing the possibility of damage to the crushing wheels 5 due to impact, enhancing the service life of the gravel device.

[0040] When there are smaller and lighter stones, they may be blocked by the baffle 8 and unable to enter the crushing box 1. By rotating the handwheel 1007, the driving bevel gear 1006 is driven to rotate, then driving the driven bevel gear 1005 to rotate, further driving the screw rod 1004 to rotate, and driving the limiting plate 1001 to move downward along the movable rod 1009 and the movable column 1008. As a result, the moving path of the moving rod 1002 along the moving groove 1003 is restricted, which can adjust the opening size between the two baffles 8 and can also directly manually adjust the position of the moving rod 1002 to make the baffle 8 rotate, improving the applicability of the gravel device.

[0041] After the stone is crushed by the crushing wheel 5, it will fall on the surface of the discharge table 11. Since the discharge table 11 is inclined, the crushed stone will be discharged through the discharge port 12 along the surface of the discharge table 11 under the action of gravity.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
