Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a sand and gravel screening device for building construction. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment, to meet people's needs for production, residence, study, and public activities. Construction sand and gravel are the main construction materials. Before use, construction sand and gravel need to be screened, which requires the use of sand and gravel screening devices.

[0003] According to the patent application CN 220559780U, a sand and gravel screening device for construction is disclosed, "This utility model discloses a sand and gravel screening device for construction, including a fixed frame. From top to bottom, the fixed frame is arranged with an inlet hopper, a fixed frame, and an outlet hopper. The inlet hopper is used to hold the sand and gravel to be filtered. The fixed frame has symmetrically arranged transverse grooves on both sides. A screen frame slides within the transverse grooves via a sliding shaft. Guide columns are provided at both the front and rear ends of the screen frame. Return springs are fitted onto the guide columns, and the other end of the return springs is connected to the interior of the transverse grooves. The sliding shaft is controlled by a crank-rocker mechanism to move back and forth laterally. This utility model provides a sand and gravel screening device for construction, which allows the screen to move relative to the sand and gravel, preventing sand and gravel from accumulating on the screen and improving the screening effect."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model controls the sliding shaft to move back and forth along the transverse groove set on the fixed frame through a crank rocker mechanism, driving the drying rack to move back and forth. The reset spring plays an auxiliary role in resetting. In actual use, because the drying rack is fixedly installed, it cannot well meet the screening requirements of different mesh sizes. At the same time, the feeding process of this device directly uses a conveyor belt to feed materials, which is prone to causing blockage due to excessive material feeding at one time. Therefore, it is necessary to improve the sand and gravel screening device for construction to solve the above problems. Utility Model Content

Example

[0035] Based on Embodiment 1, the existing technology directly uses a conveyor belt for feeding, which easily leads to blockages due to excessive material feeding at one time. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problems. Please refer to Embodiment 2. Figure 7 Furthermore, in conjunction with Embodiment 1, the auxiliary feeding mechanism 7 includes a support base 71, which is fixedly connected to the left side of the feeding box 5.

The dispersing column 75 disperses the sand and gravel entering the feed box 5 and feeds it in batches. The vibration motor 3, in conjunction with the filter plate 621, begins to screen the sand and gravel. The first motor 613 rotates the threaded rod 617, which, in conjunction with the limiting rod 616, causes the movable cleaning plate 614 to move. When adjustments are needed to meet different screening requirements, the operator selects a filter plate 621 with a suitable mesh size and inserts it into the screening box 1. The operator pulls the sliding plate 624, which, in conjunction with the spring 626, causes the locking block 625 to move. In conjunction with the fixing block 622, the filter plate 621 is installed and positioned between the screening box 1 and the screening box 1.
