Technical Field

[0001] The utility model relates to the field of cooling, and more particularly to a water-stable gravel crushing device. Background Art

[0002] A cement-stabilized gravel crushing device is a mechanical device used to process and crush cement-stabilized gravel. Cement-stabilized gravel (also known as cement-stabilized base material or cement-stabilized gravel) is a commonly used road base material. It consists of a mixture of crushed stone, stone chips, sand, and cement, produced through mixing, paving, and compaction processes. It is used for paving surfaces such as roads and parking lots.

[0003] Existing water-stabilized gravel crushing devices are usually unable to crush all raw materials to the qualified size at one time. After completing the crushing, screening is often required, and then the raw materials that do not meet the standards are sent to the crushing device again for crushing. This process is repeated until all the raw materials are crushed to the qualified size. Such operation is time-consuming and labor-intensive, and will also reduce production efficiency.

[0004] Based on the above, the purpose of the present invention is to provide a water-stable gravel crushing device to solve the above problems. Utility Model Content

A crushing roller group 1 is provided in the crushing box 1, and the crushing roller group 1 includes two crushing rollers 2 that are both rotatably connected to the crushing box 1. A circulation chamber 5 is opened at the lower end of the crushing box 1, and a crushing roller group 2 is provided in the circulation chamber 5. The crushing roller group 2 includes two crushing rollers 7 that are both rotatably connected to the inner wall of the circulation chamber 5. Both sides of the inner wall of the circulation chamber 5 are rotatably connected with mounting rings 8, and a number of push plates 9 are fixedly connected between the mounting rings 8 on both sides. The crushing box 1 is respectively provided with a driving mechanism 1 and a driving mechanism 2 for driving the two crushing rollers 2 and the two crushing rollers 7 to rotate relative to each other. The crushing box 1 is also provided with a driving mechanism 3 for driving the push plate 9 to circulate around the crushing roller group 2.

[0025] Furthermore, both the drive mechanism 1 and the drive mechanism 2 include a motor 10 fixedly connected to the crushing box 1, the motor 10 is fixedly connected to the crushing roller 1 2 or the crushing roller 2 7 on one side, and the crushing roller 1 2 and the crushing roller 2 7 are fixedly connected to a driving gear 11, and the two driving gears 11 in the drive mechanism 1 and the drive mechanism 2 are engaged with each other.

[0026] Furthermore, the driving mechanism three includes a gear ring 12 fixedly connected to the mounting ring 8 on one side, a rotating shaft 13 is rotatably connected to the crushing box 1, and a driven gear 14 and a driven gear 2 15 are fixedly connected on both sides of the rotating shaft 13. The driven gear 1 14 is meshed with the gear ring 12, and the driven gear 2 15 is meshed with a side driving gear 11 in the driving mechanism two.

[0027] Furthermore, guide plates 16 are provided on both sides of the second crushing roller group, and the guide plates are fixedly connected to the inner wall of the circulation chamber.

[0028] Furthermore, a shielding portion 17 is formed on the guide plate 16 .

[0029] Furthermore, a plurality of filter holes are provided on the push plate.

[0030] Furthermore, the push plates are distributed in a circular array, and the number of the push plates is greater than or equal to 6.

[0031] Working principle: When water-stabilized stone crushing is required, the motors 10 in the driving mechanism 1 and the driving mechanism 2 respectively drive one crushing roller in the crushing roller group 1 and the crushing roller group 2 to rotate, and the crushing roller will drive the crushing roller on the other side to rotate through the two driving gears 11.
