Embodiment Construction

[0032] Such as Figure 1 to Figure 14 As shown, the present invention includes a first conveyor 1, a buffer assembly 2, a primary screening assembly 3, a guide plate 4, a second conveyor 5, a distribution assembly 6, a secondary screening assembly 7 and a third Conveyor 8, the present invention is described below in conjunction with accompanying drawing.

[0033] Such as figure 1 As shown, the sand to be screened is provided on the first conveyor 1, and the first conveyor is used for transporting the sand to be screened. There is a buffer assembly 2 at the end of the first conveyor, such as figure 2 As shown, the buffer assembly includes a first frame 21, a column 22, a first spring 23, a pole 24, a swash plate 25 and a rubber pad 26, the first frame is the base of the buffer assembly, and the first frame is used for Install other components. Several vertical columns 22 are arranged on the top of the first frame, and the lengths of the columns increase successively from l...

Abstract

The invention discloses a gravel screening device and relates to the technical field of gravel screening in electric power construction. The gravel screening device is used for efficiently screening gravel with different grain diameters. The kinetic energy of gravel is reduced under the action of a buffering assembly, the gravel falls in a primary conveying assembly, primary screening is conducted in the primary screening assembly, gravel with large grain diameters is screened out and conveyed through a conveyor, gravel with small grain diameters falls into a diverting assembly and evenly falls into a secondary screening assembly, screening is conducted on the gravel again in the secondary screening assembly, the gravel with the large grain diameters is screened out, and the gravel with the small grain diameters falls on the conveyor to be conveyed out. When the gravel is clamped into a first screening hole, wobbling of a first screen is achieved under the action of an air cylinder and an electromagnetic sucker, and the gravel wobbles out of the first screening hole. The gravel with different grain diameters can be screened, the screening efficiency is high, and the screened gravel can be conveniently collected and transported.

Description

technical field [0001] The invention relates to the technical field of sand and gravel screening in electric power construction, in particular to a screening device for separating sand and gravel with various particle sizes. Background technique [0002] In the process of electric power construction, it is necessary to use sand and gravel with different particle sizes according to different gradations. When the construction unit screens sand and gravel, it usually places an inclined sieve on the ground, scoops up sand and gravel through a shovel and pours it directly on the sieve, so as to realize simple screening of sand and gravel. In this case, the screening of sand and gravel is not thorough, and the work efficiency is low, so it is difficult to guarantee the quality of electric power construction. Therefore, there is an urgent need for a sand screening device for screening sand of different particle sizes. Contents of the invention [0003] The object of the present...
