Embodiment 1

[0029] refer to Figure 1-3 , a stone screening device for road construction, comprising a screening box 1, the two sides of the top outer wall of the screening box 1 are connected with a box cover 11 by bolts, and the top outer wall of the box cover 11 is provided with a feed port 14, and the feed port 14 The edge of the inner wall of the tank is connected with a feed hopper 12 by bolts, and the opposite inner walls of the feed hopper 12 are connected with stoppers 13 by bolts, and the outer walls of both sides of the box cover 11 are provided with slag outlets 10, and The bottom inner walls of the two slag discharge outlets 10 are connected with a support plate 9 by bolts. The shape of the support plate 9 is U-shaped. The top outer wall of the support plate 9 is provided with a guide opening 16, and the top outer wall of the support plate 9 is connected by bolts. plate 15, and the shape of the diverter plate 15 is V-shaped, barbs are provided on both sides of the diverter pl...

Embodiment 2

[0040] refer to Figure 4 , a stone screening device for road construction. Compared with Embodiment 1, the two sides of the outer wall of the top of the box cover 11 are connected with vibration motors 26 by bolts. After the screening is completed, start the vibration motor 26, thereby passing the vibration motor The vibration generated by 26 handles the stone debris adhering to the inside of the device, so as to clean the inner wall of the device.

[0041] Working principle: when in use, the stones that need to be screened are loaded into the inside of the screening box 1 through the feed hopper 12 and the feed port 14, and pass through the stopper 13, the V-shaped diverter plate 15 and the stepped barb, when the When the stones are loaded into the inside of the screening box 1, the stones can be blocked by the stopper 3 and the barbs, so as to slow down the falling speed of the stones, thereby facilitating the screening of the stones, and preventing the stones from falling ...

Abstract

The invention discloses a stone screening device for highway construction. The stone screening device comprises a screening box, box covers are fixedly connected to the two sides of the outer wall ofthe top of the screening box, a feeding port is formed in the outer wall of the top of each box cover, a feeding hopper is fixedly connected to the edge of the inner wall of each feeding port, and a stop block is fixedly connected between the inner walls of the two opposite sides of each feeding hopper; and slag discharging openings are formed in the outer walls of the two sides of the box covers,supporting plates are fixedly connected to the inner walls of the bottoms of the two slag discharging openings, the supporting plates are each in a U shape, guide openings are formed in the outer walls of the tops of the supporting plates, and splitter plates are fixedly connected to the outer walls of the tops of the supporting plates. According to the stone screening device, stones can be prevented from being accumulated together to block the interior of the device, the situation that a space between every two adjacent partition plates is blocked due to the fact that the sizes of the stonesare large can be prevented, the stones can be screened through vibration generated when the stones fall, and the stone screening efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a stone screening device for road construction. Background technique [0002] During road construction, stones of uniform size are generally required, so the stones need to be screened to facilitate the laying of roads. [0003] After retrieval, the Chinese patent authorization number is the patent of CN107838024B, which discloses a stone screening device for road construction. The technical problem to be solved by the present invention is to provide a stone screening device for road construction with uneven screening, high stone screening efficiency, cleaning and separation of stones. In order to solve the above-mentioned technical problems, the present invention provides such a gravel screening device for road construction, including sliding bars, etc.; the present invention is provided with two sliding bars, a sliding sleeve is arranged on the left sliding bar, and ...
