The utility model relates to the technical field of mortar sand production equipment, in particular to mortar sand screening equipment which comprises a screening box, and grooves are formed in the inner walls of the two sides of the screening box. Mortar sand is poured into the screening box through the feeding port and accumulated above the screen cloth on the upper portion, the driving motor is started to drive the circular plate to rotate, the circular plate is connected with the concentric-square-shaped plate through the connecting rod so that the concentric-square-shaped plate can do reciprocating motion, and the concentric-square-shaped plate enables the screen cloth to vibrate in the screening box through the connecting plate. Due to the fact that the apertures of the screen holes of the two screens are different, mortar sand materials with different sizes can be screened out, coarse sand materials are gradually stacked above the corresponding screens and move out of the screening box through the rectangular holes along with vibration of the screens, and finer sand materials can continue to fall off and be discharged out of the screening box through the discharging port. According to the mortar sand screening equipment, automatic and continuous screening and classification of mortar sand can be achieved, the screening efficiency and accuracy are improved, and the manual labor intensity is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of mortar sand material production equipment, in particular to mortar sand material screening equipment. Background Art

[0002] Sandstone refers to a loose mixture of sand and gravel. In daily life, some people also call sandstone "sandstone". Sandstone has uniform particles, fine texture, and loose structure, so it has a high water absorption rate (higher cost when protecting), and has the characteristics of sound insulation, moisture absorption, damage resistance, weathering resistance, fading resistance, insolubility in water, and no radioactivity.

[0003] However, most construction sites currently still use traditional manual screening methods, that is, workers use tools such as shovels to screen through screens. This method has many problems and limitations. From the perspective of labor intensity, manual screening of mortar sand requires workers to swing shovels for a long time and at a high intensity, and perform repetitive physical labor, which not only increases the workers' fatigue level, but may also lead to reduced work efficiency and frequent safety accidents. Especially in large-scale construction projects, the workload of manual screening is huge, and often requires a large number of workers to work at the same time, further aggravating the problem of labor intensity. For this reason, we propose a mortar sand screening equipment to solve the above problems. Utility Model Content

After the driving motor 9 is started, the circular plate 10 is driven to rotate. The circular plate 10 is connected to the circular plate 12 through the connecting rod 11, so that the circular plate 12 reciprocates. The circular plate 12 is connected to the screen 7 through the connecting plate 13, so that the screen 7 vibrates in the screening box 1. At the same time, the moving plate 6 drives the slider 4 to slide on the corresponding positioning rod 3. The slider 4 compresses the corresponding spring 5 during the movement, and the material passes through the two The screen 7 performs automatic multi-stage screening. Since the apertures of the two screens 7 are different, when the screen 7 vibrates, mortar sand materials of different sizes will be screened out.
