[0026] 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.

[0027] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a grain sorting machine, including a shell 4, the top of the shell 4 is rotatably connected with an opening adjustment plate 6, the opening adjustment plate 6 can facilitate the staff to control the speed of feeding, the top of the shell 4 is provided with a pouring port 1, the pouring port 1 can facilitate the staff to pour the grain into the inside of the shell 4 for screening, one side of the shell 4 is provided with a discharge port 2, the discharge port 2 can facilitate the removal of the screened grain, the inside of the shell 4 is fixedly connected with a guide rail 12, the top of the guide rail 12 is provided with a weighing sensor 11, the weighing sensor 11 can measure and weigh the screened grain, the top of the weighing sensor 11 is fixedly connected with a collecting box 10, the collecting box 10 can collect the screened grain, so as to facilitate the distinction of grains of different sizes, the top of the collecting box 10 is fixed It is fixedly connected with a baffle 14, which can limit the grain while screening, so as to prevent mixing during screening. A connecting plate 15 is slidably connected to the inside of the shell 4, and a screen 7, a screen 2 8 and a screen 3 9 are fixedly connected to one side of the connecting plate 15. When the connecting plate 15 moves, it will drive the screen 1 7, the screen 2 8 and the screen 3 9 to move at the same time, so that vibration can be easily generated, and then the grain can be easily screened.
