[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] like Figure 1-2As shown, the grain pneumatic tee of this embodiment includes a shell 1, a movable block 2 in the inner cavity of the shell 1, and a pneumatic cylinder 3. Discharge pipes 4 are arranged at the lower positions on the left and right sides of the shell 1. The discharge pipes 4 are staggered and used to transport grain. The movable block 2 is provided with a first discharge hole 5 located at the lower position on the left and right sides and a second discharge hole 6 located at the upper position on the left and right sides. The second discharge hole 6 is staggered. A connecting groove 7 is opened on the movable block 2. The connecting groove 7 is connected to the first discharge hole 5 and the second discharge hole 6 respectively. The staggered discharge pipe 4 and the second discharge hole 6 as well as the first discharge hole 5 can transport grain in a reverse direction.
