Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement loading and unloading technology, and more specifically, to a cement loading and unloading device. Background Technology
[0002] Cement is an important building material, mainly made from limestone, clay and other raw materials that are calcined at high temperatures and then ground. It has the property of hardening and solidifying when it comes into contact with water. It is mainly used in concrete, mortar and precast components. Cement is also an essential material in the construction process. Because the amount of cement used each time is relatively large, it is loaded and unloaded in a whole truckload each time. Loading and unloading devices are usually placed at the rear of the vehicle.
[0003] Traditional cement loading and unloading equipment is mostly a fixed, integrated inclined frame. Although it can unload materials, it is not convenient to adjust its receiving height according to the height of the loading and unloading vehicles, which affects the flexibility of the equipment during use.
[0004] Furthermore, the existing loading and unloading equipment requires manual assistance in handling cement bags during loading and unloading, which is time-consuming and labor-intensive, affecting the overall efficiency of the equipment during use. Utility Model Content
