Embodiment 1

[0026] refer to Figure 1 to Figure 4 As shown, a vibrating screen box air-locking and discharging device is improved in that it includes a flap mechanism 4 and a flap driving device 5, and the flap mechanism 4 includes a flap 41 installed at the bottom of the screen box 1, The upper end of the turning plate 41 is fixedly connected to the rotating shaft 47, and the rotating shaft 47 is connected to the screen box 1 in rotation so that the turning plate 41 can be turned over in the screen box 1, and the turning plate driving device 5 is arranged outside the screen box 1 At least one side of the rotating shaft 47 is fixedly connected; the turning plate driving device 5 includes a cylinder 51 fixedly installed on the outside of the screen box 1, and the output rod end of the cylinder 51 is rotatably connected with a connecting rod 54. The other end of the connecting rod 54 is fixedly connected to the end of the rotating shaft 47, and is used to drive the rotating shaft 47 to rota...

Embodiment 2

[0045] On the basis of embodiment 1, with reference to image 3 As shown, rubber plates 43 are respectively installed on the left side and the right side of the turnover plate 41 .

[0046] Further, the left side and the right side of the turning plate 41 are respectively equipped with fixing plates 44 , and the rubber plate 43 is installed between the side edges of the turning plate 41 and the fixing plates 44 .

[0047] Further, the fixing plate 44 is fixedly connected to the turning plate 41 by bolts, and the setting of the fixing plate 44 makes the connection between the rubber plate 43 and the turning plate 41 more firm.

[0048] In this embodiment, the setting of the rubber plate 43 makes the contact between the side of the flap 41 and the bottom of the screen box 1 change from rigid contact to flexible contact. On the one hand, it can reduce the contact between the flap 41 and the bottom of the screen box 1 during the turning process The damage caused by the collision,...

Embodiment 3

[0052] On the basis of any of the above-mentioned embodiments, the number of the turning plate driving device 5 is two, and the two turning plate driving devices 5 are symmetrically installed outside the screen box 1 and connected to both ends of the rotating shaft 47 .

[0053] In this embodiment, both sides of the turnover mechanism 4 are provided with a turnover driving device 5, so that the response sensitivity of the turnover mechanism 4 is higher, the movement is more stable, and the driving effect is better.

[0054] It should be pointed out that the above detailed description is exemplary and intended to provide further explanation for the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

Abstract

The invention relates to a vibrating screen box air locking and discharging device. The vibrating screen box air locking and discharging device comprises a turning plate mechanism and a turning plate driving device, the turning plate mechanism comprises a turning plate installed on the lower portion of a screen box, the upper end of the turning plate is fixedly connected with a rotating shaft, the rotating shaft is rotationally connected with the screen box so that the turning plate can overturn in the screen box, the turning plate driving device is arranged on at least one side of the outer part of the screen box and is fixedly connected with the rotating shaft, the turning plate driving device comprises an air cylinder fixedly installed on the exterior of the screen box, the end part of an output rod of the air cylinder is rotationally connected with a connecting rod, the other end of the connecting rod is fixedly connected with the end part of the rotating shaft and is used for driving the rotating shaft to rotate so that the turning plate can overturn up and down, when the turning plate is respectively located at the limiting positions for overturning up and down, one side edge of the turning plate is abutted with the bottom end of the screen box so that a closed space can be formed in the interior of the screen box. The vibrating screen box air locking and discharging device has the beneficial effects of being simple in structure, low in cost and low in failure rate.

Description

technical field [0001] The invention relates to the technical field of construction waste sorting equipment, in particular to a vibrating screen box air lock and discharge device. Background technique [0002] Construction waste refers to the construction waste produced by man-made or natural reasons in the project, including waste residue, spoil, silt and waste materials, etc. Many wastes in construction waste can be reused as renewable resources after being sorted, removed or crushed, so construction waste sorting equipment is required. At this stage, equipment for high-precision sorting of construction waste through the combined action of vibration and wind has appeared on the market. Existing technologies such as Figure 6 As shown, the external blower sends air into the lower air chamber of the screen box a through the air inlet c, and the material entering the screen plate b through the feed port is under the double action of wind force and vibration, and the diameter...
