Technical Field

[0001] The utility model belongs to the field of waste treatment, and in particular relates to a waste crushing device for construction engineering. Background Art

[0002] In construction projects, waste crushing devices are mainly used to process and recycle construction waste, including concrete, bricks, stones, etc., which helps to reduce the volume of waste and improve the recycling rate of resources.

[0003] When existing crushing devices are used for crushing construction waste, general crushing devices often use high-horsepower motors to drive crushing rollers to crush the construction waste. However, some construction waste has a high hardness, and general motors often find it difficult to provide the crushing rollers with the corresponding torque to crush it efficiently. In addition, the particles of the crushed construction waste are of different sizes. When they are subsequently recycled and used, they need to be screened before they can be used again.

[0004] Therefore, in order to address the problem that when the above-mentioned existing crushing device is used for crushing construction waste, its crushing structure is not effective in crushing high-hardness construction waste, and the crushed construction waste is not convenient for subsequent processing, a waste crushing device for construction projects is developed. By adding a reduction transmission structure, a high-frequency screening structure and a dust-proof structure to the crushing device, the crushing device can efficiently crush construction waste with higher hardness, and the high-frequency screening structure can perform secondary screening on the crushed construction waste to improve the convenience of subsequent recycling processing.

The first gear 12 with high torque drives the two second gears 14 to drive the two crushing rollers 13 to efficiently crush the construction waste, and the screening component screens the crushed construction waste to improve the convenience of subsequent recycling of construction waste.

[0025] See also Figure 3 In this embodiment, the servo motor 9 is located at the left end of the reducer 10. The servo motor 9 and the reducer 10 are both arranged in the dust cover 4. The left end of the dust cover 4 is a through-type cover. When in use, the dust cover 4 can provide better dust protection for the servo motor 9 and the reducer 10. The first gear 12 is arranged between the two second gears 14. The crushing roller 13 is divided into two. When in use, the first gear 12 can drive the two second gears 14 to drive the crushing roller 13 to rotate. A first trough 8 is opened through the center of the upper and lower ends of the support platform 3. The front and rear ends of the support platform 3 are fixed with a mounting frame 7.

When in use, the feed hopper 1 can facilitate workers to pour construction waste into the device for crushing.
