Embodiment 1

[0032] Such as Figure 1-Figure 10As shown, the present invention provides a technical solution: a pre-raw material screening device prepared by concrete for civil engineering, including a base 3, a screening mechanism 2 is arranged above the base 3, and a feeding mechanism 1 is arranged above the screening mechanism 2, Feeding mechanism 1 comprises vertical plate 101, rotating column 102, No. 1 motor 103, and vertical plate 101 inner side is provided with rotating column 102, and vertical plate 101 front portion is provided with No. 1 motor 103, and rotating column 102 is provided with feeding plate 104, and feeding plate 104 is provided with non-slip rubber pad 105; described sieving mechanism 2 comprises sieve plate 201, stopper 202, baffle plate 203, and sieve plate 201 is provided with stopper 202, and stopper 202 inner side is provided with baffle plate 203, A vibration motor 204 is installed on the side of the sieve plate 201, a spring 205 is arranged on the lower end o...

Embodiment 2

[0036] Such as Figure 5 As shown, the difference between Embodiment 2 and Embodiment 1 is that the sieving mechanism 2 includes a sieve plate 201, a stopper 202, and a baffle 203, the sieve plate 201 is provided with a stopper 202, and the inner side of the stopper 202 is provided with a stopper Plate 203, a slide table 209 is provided below the sieve plate 201, a slide rail 210 is arranged on the slide table 209, and an electric telescopic column 211 is installed on the side of the slide table 209.

[0037] The vibrating motor 204 drives the sieve plate 201 to vibrate on the spring 205 to sieve the raw materials, and replaces it with an electric telescopic column 211 to drive the slide table 209 to reciprocate rapidly on the slide rail 210, so that the sieve plate 201 moves continuously, and the Raw materials are screened.

Abstract

The invention discloses a raw material pre-sieving device for concrete preparation for civil engineering. The device comprises a base; a sieving mechanism is arranged above the base; a feeding mechanism is arranged above the sieving mechanism; the feeding mechanism comprises a vertical plate, a rotating column and a No.1 motor; the rotating column is arranged on the inner side of the vertical plate; the No.1 motor is arranged at the front part of the vertical plate; a feeding plate is arranged on the rotating column; and a non-slip rubber pad is arranged on the feeding plate. The device is simple in structure, reasonable in design and low in production cost, sieving of raw materials is greatly facilitated, the manpower is saved, the working efficiency is improved, and the device has the high practical value.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a pre-raw material screening device for preparing concrete for civil engineering. Background technique [0002] Civil engineering refers to the planning, construction and maintenance of all infrastructure related to culture, soil and water. It refers to the investigation and planning of buildings and related supporting facilities for new construction, reconstruction or expansion of various projects other than housing construction. , design, construction and other technical work and the completed engineering entities. [0003] In the process of concrete preparation, raw materials need to be screened, but now it is done manually, which is time-consuming and labor-intensive, and the work efficiency is low. Contents of the invention [0004] The object of the present invention is to provide a screening device for pre-raw material prepared by concrete for civil engineerin...
