Problems solved by technology

[0002] The stones in the raw materials in the existing domestic highway construction are all multi-level mixtures, that is, a certain stone contains 3 to 4 kinds of stones with different percentages, which leads to the use of stones after entering the mixing equipment. It is difficult to control the grading accuracy in the process, and it cannot meet the requirements of high-grade roads, which will affect the quality and life of the road surface

Embodiment Construction

[0010] As shown in the figure: an inclined upper screening machine 5 is installed on the upper part of the frame 4, and an inclined lower screening machine 6 is installed on the frame 4 below the upper screening machine 5. The feeding port of the sub-machine 6 is connected; it is characterized in that: the upper screening machine 5 and the lower screening machine 6 all include two layers of screens; stone outlets are set at the outlet of each layer of screens; the upper screening machine 5 and the The outlet under the net of the upper screen cloth in the lower screening machine 6 is the entrance of the lower screen cloth. Each layer of screens includes two screens, and the two screens are connected to each other by fasteners 10 . According to the positions of the two screens E and G, two stone material outlets 15, 14 are respectively set under the lowermost screen cloth E, G.

[0011] When working, the stones that need to be screened first enter the feed end of the upper scre...

Abstract

The invention relates to graded screening equipment for stone used in highway construction, in particular to a single-grade stone fine screening mechanism. According to a technical proposal provided by the invention, the upper part of a machine frame is provided with an inclined upper screen grader, an inclined lower screen grader is arranged on the machine frame under the upper screen grader, and the discharging port of the upper screen grader is communicated with the feed port of the lower screen grader. The single-grade stone fine screening mechanism is characterized in that: both the inside of the upper screen grader and the inside of the lower screen grader comprise two layers of screen mesh; the position of the mesh upper outlet of each layer of the screen mesh is provided with a stone outlet; and the mesh lower outlets of the upper-layer screen meshes in the upper screen grader and the lower screen grader are the inlets of the lower-layer screen meshes. The graded screening equipment can finely grade the stone and improve the quality of constructed pavement.

Description

technical field [0001] The invention relates to a grading and screening device for stone materials in road construction, in particular to a fine screening mechanism for single-grain stone materials. Background technique [0002] The stones in the raw materials in the existing domestic highway construction are all multi-level mixtures, that is, a certain stone contains 3 to 4 kinds of stones with different percentages, which leads to the use of stones after entering the mixing equipment. It is difficult to control the grading accuracy in the process, and it cannot meet the requirements of high-grade highways, which in turn affects the quality and life of the road surface. Contents of the invention [0003] The purpose of the present invention is to design a fine screening mechanism for single-grained stone materials, so as to finely classify the stone materials and improve the quality of the paved road surface. [0004] According to the technical scheme provided by the pre...
