Description

Technical Field

[0001] The utility model relates to the technical field of sand making machines, in particular to a sand making machine for construction engineering. Background Art

[0002] Construction engineering refers to the planning, investigation, design, construction, completion and other technical work and completed engineering entities for the construction, reconstruction or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines and equipment. It also refers to the construction of various houses and buildings, also known as construction workload. This part of the investment must be started and materials must be moved, and it can only be realized through construction activities. When the construction project is implemented, a large amount of construction raw materials is needed, and sand and gravel are the most widely used materials in the construction field. With the depletion of natural sand and gravel and the increase in the government's environmental protection efforts, natural sand and gravel resources are becoming increasingly depleted. Artificial sand and gravel have become the mainstream of the sand and gravel industry, and are generally made by sand making machines.

[0003] The patent document with announcement number CN217856431U discloses a sand making machine for construction engineering, including a sand making box, the top and bottom of which are respectively constructed with a feed port and a discharge port, and a box door is provided on one side of the box body; a crushing device, which is installed inside the sand making box and is used to crush the sand and gravel raw materials; a screening assembly, which is installed inside the sand making box. The utility model screens the crushed sand and gravel through the screening device, and the qualified sand and gravel fall to the bottom of the sand making box, and the unqualified sand and gravel stay on the screening plate. After the sand making is completed, the box door can be opened to process the unqualified large-particle coarse sand and gravel on the screening plate. The operation is simple and convenient, saving manpower, avoiding the screening of sand and gravel manually or by screening equipment, increasing the workload of the staff, reducing the sand making efficiency, and also increasing the cost of sand making. However, the prior art still has defects:

[0004] (1) The sand making machine in the prior art has poor adhesion between the sand and the crushing roller during the processing, which causes the sand and the gravel to slip easily between the crushing rollers, affecting the crushing efficiency of the sand and the gravel.

[0005] (2) The sand making machine of the prior art is not convenient for automatically exporting and collecting unqualified large-particle coarse sand and gravel. After the sand making is completed, the box door needs to be opened and the unqualified large-particle coarse sand and gravel on the screening plate need to be manually removed for subsequent processing, which is time-consuming and labor-intensive and increases the workload of the staff.
