Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to a sand screening device for construction engineering. Background Art
[0002] Construction engineering refers to the process of transforming buildings and structures from conceptual ideas into real entities through a series of activities such as planning, design, and construction. This process covers the early feasibility study, planning and design, program review, construction drawing design, mid-term construction preparation, on-site construction, and the later completion acceptance and delivery. Construction engineering involves many disciplines, including civil engineering, structural engineering, architecture, water supply and drainage, HVAC, electrical engineering, landscape design, cost management and other professional fields.
[0003] In construction projects, sand is one of the important aggregates for concrete. Unscreened sand may contain impurities such as soil, gravel, shells, and plant debris, which will reduce the density and strength of concrete and affect the durability and structural performance of concrete. Screening sand can remove impurities and ensure that the quality of concrete meets the design requirements.
[0004] After searching, it was found that large-scale engineering sand screening machines in the existing technology usually do not have the function of autonomous loading. Due to the height of the equipment, it is impossible to load materials manually or with small loading equipment. The purchase cost of large loading equipment is high, and the daily maintenance, fuel consumption, insurance costs, and repair costs are also much higher than those of small equipment or manual labor. This undoubtedly increases the operating cost of the project. Utility Model Content
[0005] The utility model aims to provide a sand screening device for construction engineering, which has the advantage of lifting materials from a low place and loading them manually or with a small loading device, thereby solving the problem that large-scale engineering sand screening machines cannot be loaded manually or with a small loading device, resulting in high operating costs for engineering projects.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] 1. The utility model drives the sliding frame to move inside the lifting frame by rotating the screw to complete the lifting and falling action of the lifting bucket.

[0022] During use, the sliding frame 303 is driven to move inside the lifting frame 301 by rotating the screw rod 302 to complete the lifting and falling action of the lifting bucket 305. In this process, after the gear 307 moves to one side of the rack 308 and engages with it, the gear 307 drives the connecting rod 304 and the lifting bucket 305 to flip, and the material inside the lifting bucket 305 is dumped into the inside of the feeding mechanism 2.

[0026] During use, the vibration motor 103 drives the screen box 102 to vibrate at the bottom of the mounting base 101. When sand enters the screen box 102 and the fine sand falls from the top of the screen plate 104 under the action of vibration, the impurities remain on the top of the screen plate 104 and are discharged through two sets of discharge ports 105 respectively, completing the sand screening operation.

[0031] Furthermore, the feeding mechanism 2 includes a mounting frame 201, and a feeding hopper 202 is fixedly installed inside the mounting frame 201;
