Embodiment 1

[0019] see Figure 1-2 , a gravel screening device for road and bridge construction, comprising a base 1, a feeding device and a screening device, wherein the feeding device is arranged on one side of the screening device, and the sand and gravel are transported to the screening device by the feeding device Among the devices, the labor of manpower is further reduced; the feeding device includes a first conveyor belt 3 and a conveying motor 5, and the support frame 4 through which the first conveyor belt passes is fixedly installed on the base 1, and the conveying The motor 5 is leveled on the first conveyor belt 3 by the belt, and then the first conveyor belt 3 is further driven to move by the conveying motor 5; the screening device includes a screening box 19, a screen cloth one 13, Screen two 14, the second discharge port 11 and the third discharge port 12, the screen one 13 and the screen two 14 are respectively arranged on the screening box 19, the second discharge port 11...

Embodiment 2

[0026] In order to improve the actual use effect of the device, the present embodiment has made the following improvements on the basis of the first embodiment. drain device.

[0027] Further, the sand leakage prevention device includes a movable plate 15 and a chute 16, the chute 16 is opened on the side wall of the screening box 19, the movable plate 15 is arranged in the chute 16, and the chute 16 A spring is arranged in the groove 16, and then under the thrust of the spring, the movable plate 15 elastically slides in the chute 15, and the end of the movable plate 15 touches on the screen one 13, and then passes through the The active plate 15 effectively prevents sand from entering the rotating cavity of the rotating wheel 17.

[0028] The working principle of this embodiment: by distributing the anti-leakage device of sand and stone on the side of screen cloth one 13 and screen cloth two 14, avoid sand and stone to enter in the rotating chamber of rotating wheel 17.

Abstract

The invention discloses a sandstone screening device for road and bridge construction. The sandstone screening device comprises a base, a material conveying device and a screening device, the materialconveying device is laid on one side of the screening device and comprises a first conveying belt and a conveying motor, the screening device comprises a screening box, a first screen net, a second screen net, a second discharging outlet and a third discharging outlet, the first screen net and the second screen net are laid on the screening box, the second discharging outlet and the third discharging outlet are laid in one side of the first screen net and one side of the second screen net correspondingly, a second conveying belt is rotationally mounted at the bottom of the screening box, final sandstone screened by the first screen net and the second screen net falls on the second conveying belt, and a vibration device is laid on the screening box. The sandstone screening device is simplein structure and powerful in function, the screening effect is improved greatly through the multi-stage screen nets in the screening box, the intensity of labor workers is reduced greatly through theconveying device, and the screening efficiency is improved.

Description

technical field [0001] The invention relates to the construction field, in particular to a sand and gravel screening device for road and bridge construction. Background technique [0002] Sand and gravel are the most common building materials in the construction industry. Sand and gravel need to be sorted when they are used. Sand and gravel with different particle sizes are used in different places. Furthermore, sand screening is the most basic process in the construction industry. [0003] For now, most of the existing sand and gravel need to be manually screened in the screening process, and the screening effect is only one time, which increases the labor intensity of construction personnel and is not efficient. Contents of the invention [0004] The object of the present invention is to provide a kind of gravel screening device for road and bridge construction, to solve the problems raised in the above-mentioned background technology. [0005] To achieve the above obj...
