Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

As shown in fig. 1, the utility model provides a debris elevator with two cars includes left car 2 and right car 3, and left car 2 and right car 3 share an elevator well 1. Compare in the conventional elevator well that is used for the debris elevator, the utility model discloses elevator well 1's width has been widened for elevator well 1 can satisfy the installation demand of two cars.
