The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 2-8, the present embodiment discloses a broadcasting device comprising a receiving tray 5 and a plurality of connecting pipes 6. With specific reference to fig. 5, wherein the receiving tray 5 includes a plurality of receiving hoppers 51, and a plurality of receiving hoppers 51 are a style of calligraphy and set up side by side, and the top of receiving hopper 51 is the rectangle, and the long limit of rectangle sets up along the width direction of receiving tray 5, and the minor face sets up along the length direction of receiving tray 5, and the purpose can arrange a plurality of receiving hoppers 51 in limited space, realizes that the multirow broadcasts simultaneously. The discharge hole 52 at the bottom of the receiving hopper 51 is oval, the major axis of the oval is arranged along the length direction of the receiving hopper 51, and four sides of the inlet of the receiving hopper 51 are nearly tangent to the oval. Since the discharge hole 52 is oval, the area of the sidewall of the receiving hopper 51 is small, and the receiving hopper is steep, there is no part with a gentle slope, the material flows to the receiving hopper 51 and then is rapidly discharged from the discharge hole 52, and if the material is wet, the material stuck on the inner sidewall of the receiving hopper 51 will also fall downward under the gravity of the material and is discharged from the discharge hole 52. The phenomenon that the material cannot be normally spread due to the blockage of the material outlet 52 caused by the adhesion of the material on the side wall of the receiving hopper 51 can be avoided.

As shown in fig. 3 and 6, the plurality of connecting pipes 6 are arranged in one-to-one correspondence with the receiving hoppers 51, the feed ports 61 of the connecting pipes 6 are oval-shaped and matched with the discharge ports 52, and the feed ports 61 are connected to the discharge ports 52. A connecting part is convexly arranged at the feed inlet 61 of the connecting pipe 6, and the discharge outlet 52 of the receiving tray 5 is inserted into the connecting part so as to connect the connecting pipe 6 to the discharge outlet 52 of the receiving tray 51. Specifically, the connecting pipe 6 is a three-way pipe, three interfaces of the connecting pipe 6 are a feed inlet 61, a discharge outlet 62 and an air inlet 63, wherein the feed inlet 61 and the discharge outlet 62 are located on the same axis, i.e., the material can directly flow along a straight line or a direction which is substantially a straight line without turning when circulating in the connecting pipe 6.
