Example 2: different from the embodiment 1, the threshing machine of the embodiment further includes a discharging plate 26 as shown in fig. 5 to 7, the discharging plate 26 is hinged to the side portion of the machine barrel 1 for opening or closing the discharging port 7, a guide groove 27 is formed in the inner wall of the machine barrel 1, a pushing plate 8 is provided with a guide protrusion 28, the guide protrusion 28 is slidably connected with the guide groove 27, a linkage rod 29 is embedded in the machine barrel 1, one end of the linkage rod 29 penetrates through the machine barrel 1 and is connected with the discharging plate 26, the other end of the linkage rod 29 extends into the guide groove 27 and is connected with the guide protrusion 28, the pushing plate 8 pushes the linkage rod 29 to open the discharging plate 26, the pushing plate 8 pulls the linkage rod 29 to close the discharging plate 26, a telescopic rod 31 with a return spring 30 is arranged between the linkage rod 29 and the discharging plate 26, one end of the telescopic rod 31 is rotatably connected with the linkage rod 29, the other end of the telescopic rod 31 is rotatably connected with the discharging plate 26, when the material pushing plate 8 moves towards the direction close to the material outlet 7, the material pushing plate 8 gradually opens the material outlet plate 26 through the linkage rod 29 and the telescopic rod 31, otherwise, when the material pushing plate 8 moves towards the direction far away from the material outlet 7, the reset spring 30 enables the material outlet plate 26 to gradually reset and finally close the material outlet 7, namely the material outlet plate 26 closes the material outlet 7 in the initial state.

The threshing method of the threshing machine of the embodiment comprises the following steps as shown in fig. 8:

a threshing step: the discharge hole 7 is closed by controlling the discharge plate 26, food enters the machine barrel 1 from the feed hole 5 and is threshed under the action of a threshing mechanism driven by the motor 2 to form a food main body and food grains, and the food grains flow out of the machine barrel 1 from the grain outlet 6.

A discharging step: the feeding port 5 is not used for feeding any more, the food main body continues to be threshed under the action of the threshing mechanism, and meanwhile, the material pushing plate 8 in the machine barrel 1 pushes the food main body and the material discharging plate 26 to open the material discharging port 7 under the driving action of the motor 2, so that the food main body flows out of the machine barrel 1 from the material discharging port 7.

And the threshing step and the discharging step are alternately carried out until the whole threshing work is finished, namely, the circulation of the threshing step, the discharging step and the threshing step can be realized by controlling the feeding of the feeding hole 5, and then the discharging step is carried out, because the process of the discharging step is that the material pushing plate 8 has a material pushing stage, a pause stage and a reset stage, namely, the material pushing plate 8 can control the feeding of the feeding hole 5 in the pause stage and the reset stage and stop the feeding of the feeding hole 5 in the material pushing stage, or the material pushing plate 8 can control the feeding of the feeding hole 5 in the reset stage and stop the feeding of the feeding hole 5 in the material pushing stage and the pause stage. When the material pushing plate 8 is in the material pushing stage, the material pushing plate 8 moves towards the direction close to the material outlet 7 to push materials, the material pushing plate 8 drives the material discharging plate 26 to gradually open the material outlet 7, when the material pushing plate 8 moves to the material pushing limit position, the material discharging plate 26 completely opens the material outlet 7, when the material pushing plate 8 is in the pause stage, the material pushing plate 8 keeps pausing at the material pushing limit position for a period of time, the pausing time of the material pushing plate 8 at the material pushing limit position is T, T is not less than 4S and not more than 10S, preferably 7S, so as to improve the material discharging effect, when the material pushing plate 8 is in the reset stage, the material pushing plate 8 moves towards the direction far away from the material outlet 7 to reset, the material pushing plate 8 drives the material discharging plate 26 to gradually close the material outlet 7, when the material pushing plate 8 moves to the initial position, the material discharging plate 26 completely closes the material outlet 7, and finally, the material pushing plate 8 is alternately switched between the material pushing stage and the material resetting stage and circulated for N times, and then the material discharging step is finished, the setting of N depends on the type of food.
