The discharge port is opposite to the inlet port and communicates with the hollow chamber and corresponds to the position of the disc. The drive shaft unit is disposed in the feeding tube and extends outward from the discharge opening. The screw feed member is disposed on the drive shaft unit and corresponds to the feed tube, and is configured to push the grain from the feed port to the dispersion tray through the discharge port. The bottom end of the drive shaft is coupled to the dispersing disc, and the rotational axis is perpendicular to the drive shaft unit. The steering gear includes a driving tooth portion coaxially disposed on the driving shaft unit and located outside the discharging port, and a driven tooth portion coaxially disposed at a top end of the driving shaft and engaging the driving tooth portion. The drive is coupled to the drive shaft unit and is configured to drive the drive shaft unit to rotate from the shaft, and drive the drive shaft to rotate coaxially through the steering gear, thereby driving the dispersing disc to rotate.

The function of the present invention is that the steering shaft unit and the transmission shaft are connected to each other by the steering gear. Therefore, the present invention can simultaneously drive the screw feeding only by a driver connecting the driving shaft unit. The pusher grain and the dispersing disc rotate, so that space saving and economical effect can be achieved.

Other features and effects of the present invention will be apparent from the following description of the drawings, wherein: FIG. 1 is a plan view of a grain dryer; FIG. 2 is a partial cross-sectional view of the prior art. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 3 is a partial cross-sectional view showing a preferred embodiment of a driving device for a dispersing disc of the novel grain dryer; and FIG. 4 is a partial cross-sectional view of the preferred embodiment, illustrating a Steering gear and a joint seat.

Referring to Figures 3 and 4, a preferred embodiment of the drive unit 1 of the dispersion tray 102 of the novel grain dryer 10 is shown. The grain dryer 10 includes a casing 101 defining a hollow chamber 103, and the dispersion tray 102. The driving device 1 is adapted to be mounted on the hollow chamber 103, and includes a feeding tube 11, a driving shaft unit 12, a screw feeding member 13, a transmission shaft 14, a steering device 15, a joint seat 16, and a Drive 17.

The feed pipe 11 is laterally disposed at the top of the hollow chamber 103 and includes an inlet port 111 and a discharge port 112. The discharge port 112 is opposite to the inlet port 111 and communicates with the hollow chamber 103 and corresponds to the position where the disk 102 is dispersed.

The drive shaft unit 12 is disposed in the feed tube 11 and extends outwardly from the discharge port 112, and includes a pair of feed shafts 121 to be fed to the feed tube 11, one outside the discharge port 112 and coaxially connected thereto. a drive shaft 122 of the feed shaft 121, and a connection between the feed shaft 121 and the drive shaft 122 Coupling 123 between. The drive shaft 122 is coaxially connected to the feed shaft 121 through the coupling 123, and can drive the feed shaft 121 to rotate synchronously.

The screw feed member 13 is disposed on the feed shaft 121 of the drive shaft unit 12, and corresponds to the feed tube 11 and is used to push the grain from the feed port 111 through the discharge port 112 to fall onto the dispersing disc 102. Since the structure of the screw feed member 13 and the means for pushing the grain are well understood by those skilled in the art and are not characteristic of the present invention, detailed means and operations thereof will not be described herein.

The bottom end of the drive shaft 14 is coupled to the dispersing disc 102, and the rotational axis is perpendicular to the drive shaft unit 12.
