Detailed Description

In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easily understood, the invention is further described below with reference to the specific embodiments and the attached drawings, but the following embodiments are only the preferred embodiments of the invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention are described below with reference to the accompanying drawings.

As shown in figures 1-3, an electric airlock type air shutter with shock absorption performance comprises a shutter body 1, a base 11 is connected below the shutter body 1, bolt holes 5 are formed in the base 11, the shutter body 1 is fixed by fixing the base 11 through bolts, a material inlet is formed above the shutter body 1, an impeller 3 rotates in the shutter body 1, fixed disks 2 are connected to two ends of the shutter body 1 through bolts, a bearing 10 is arranged in the center of each fixed disk 2, two ends of a rotating rod in the center of the impeller 3 are rotatably connected with the bearing 10, a servo motor 4 is arranged at one end of the shutter body 1, an output end of the servo motor 4 is connected with one end of the rotating rod in the center of the impeller 3, the servo motor 4 is started to drive the impeller 3 to rotate and convey materials, the impeller 3 is in sliding contact with the inner wall of the shutter body 1, the rotating rod in the center of the impeller 3 is rotatably connected with the bearing, so that the fixed disk 2 vibrates to drive the air-closing machine body 1 and the lower base 11 to vibrate.

Close and seted up a plurality of bolt hole 5 on the outer wall of fan body 1 both ends, recess 6 has all been seted up to bolt hole 5 one side, also set up threaded hole on the fixed disk 2, fix fixed disk 2 on closing fan body 1 both ends through the bolt, set up on fixed disk 2 is close to a lateral wall of closing fan body 1 with the corresponding inside groove 7 of recess 6, be connected with spring 8 on the
