A driving shaft is fixedly connected to the contact surface between the driving motor and the tower dryer. The driving shaft extends into the tower dryer. The cylindrical surface of the driving shaft is provided with teeth, which mesh with the transmission mechanism.

[0009] As a further solution of the present invention: the transmission mechanism includes a transmission member, which is vertically slidably connected to the tower dryer, a guide groove is provided on one side of the transmission member, the guide groove cooperates with the connecting device, a slide groove is provided on the other side of the transmission member, a slide plate is provided in the slide groove, the slide plate is in sliding contact with the transmission member, a limiting groove is provided at one end of the slide plate, a rack is provided in the limiting groove, the rack is fixedly connected to the slide plate, and the rack is meshed with the tooth groove.

[0010] As a further solution of the present invention: the connecting device includes a connecting block fixedly connected to one side of the push plate, the connecting block is fixedly connected to a sliding rod, the sliding rod extends into the guide groove and is in sliding contact with the transmission member, and the other end of the push plate is fixedly connected to a vibration device.

[0011] As a further solution of the present invention: the vibration device includes a fixed frame, the fixed frame is in sliding contact with the tower dryer, the fixed frame is fixedly connected to the push plate, the fixed frame is rotatably connected to a screen, and the screen cooperates with the adjustment device.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: when the device is used, the drive motor is started, the drive motor controls the drive shaft to rotate, and the drive shaft drives the tooth groove to rotate. Since the tooth groove is meshed with the rack, when the tooth groove rotates, the tooth groove drives the rack to move vertically, wherein when the rack moves to the highest point or the lowest point, since the highest point and the lowest point of the limit groove are arc-shaped, and at the same time, in order to meet the meshing of the tooth groove and the rack, the slide plate slides left and right. When the slide plate slides left and right, the tooth groove and the rack change the meshing direction, and the rack changes the vertical movement direction to realize the reciprocating motion of up and down movement. The rack drives the transmission member to move up and down through the slide plate, and the transmission member drives the transmission member to move up and down. The guide groove moves, and since the guide groove is in a wave shape, the slide bar is located in the guide groove and in sliding contact with the transmission member, that is, when the transmission member moves, the slide bar is squeezed to make the slide bar move left and right to vibrate, and the slide bar drives the push plate to vibrate through the connecting block, and the push plate drives the screen to vibrate through the fixed frame, that is, the grain vibrates. When drying is completed, the rotating handle is rotated, and the rotating handle drives the cam to rotate through the rotating rod. Since the cam is in sliding contact with the screen, that is, when the cam rotates, the screen rotates under the action of its own gravity and the gravity of the grain, that is, the grain falls out of the tower dryer. The device can avoid the grain from piling up, improve the grain drying efficiency, and facilitate the control of the grain drying time. BRIEF DESCRIPTION OF THE DRAWINGS
