[0021] Reference Figure 1-3 A corn threshing device for corn processing includes a housing 1. The lower end of the housing 1 is provided with a plurality of symmetrically arranged support feet 2. A through groove 17 is opened at the lower end of the housing 1. A shell 3 is provided through the upper end of the housing 1. A feed inlet 4 is opened at the upper end of the shell 3. Two symmetrically arranged threshing rollers 13 are provided inside the housing 1. The feed inlet 4 is located directly above the two threshing rollers 13. The two threshing rollers 13 cooperate with each other. A drive mechanism for driving the threshing rollers 13 is provided on one side of the shell 3. The drive mechanism includes two symmetrically arranged rotating shafts 6 that are rotatably connected through the side wall of the shell 3. The two rotating shafts 6 pass through the two threshing rollers 13 respectively and are fixedly connected to them. Gears 7 are provided on the outer wall of the two rotating shafts 6. The two gears 7 mesh.

[0022] A screening mechanism for screening corn is provided between the box body 1 and the shell 3. The screening mechanism includes a discharge port 10 opened on the side wall of the shell 3, a filter screen 14 is provided between the discharge port 10 and the inner wall of the shell 3, and a discharge port 11 is opened at the rear end of the box body 1. A mesh plate 12 is provided through the discharge port 11. Both the filter screen 14 and the mesh plate 12 are inclined.

[0023] Multiple symmetrically arranged through rods are provided between the top and bottom of the box 1. All through rods pass through the mesh plate 12 and are slidably connected to it.

[0024] A transmission rod 8 is rotatably connected between the two side walls of the box 1. A cam 16 is provided on the outer wall of the transmission rod 8. A mating block 15 is provided at the lower end of the screen plate 12. The lower end of the mating block 15 is slidably connected to the outer wall of the cam 16. By causing the screen plate 12 to vibrate up and down, the corn falling on the screen plate 12 is shaken, so that the dust and impurities on the corn are discharged through the filter screen 14 from the channel 17. The cleaned corn is discharged through the discharge port 11, which achieves the effect of cleaning the corn and brings convenience to people.

[0025] One of the rotating shafts 6 and the outer wall of the transmission rod 8 are equipped with synchronous pulleys 9. The two synchronous pulleys 9 are connected by a synchronous belt. The side wall of the housing 3 is equipped with a mounting frame, and the power motor 5 is installed in the mounting frame. The end of the output shaft of the power motor 5 is connected to the outer wall of the other rotating shaft 6. By setting the synchronous pulleys 9 and the synchronous belt between the transmission rod 8 and one of the rotating shafts 6, when the power motor 5 drives the threshing roller 13 to perform threshing, the screen plate 12 will vibrate at the same time, which improves the overall linkage of the device.

[0026] In use, corn is placed into the housing 3 through the feed inlet 4. The power motor 5 is started, causing one of the rotating shafts 6 to rotate. The meshing of the gears 7 between the two rotating shafts 6 causes the two rotating shafts 6 to drive the two threshing rollers 13 at the same speed but in different directions, thus threshing the corn (since the threshing rollers 13 are existing technology, their structure is not described in detail in this drawing). After threshing, the corn and corn cobs fall onto the filter screen 14. The corn cobs are discharged from the housing 3 through the discharge port 10 due to the inclined arrangement of the filter screen 14, while the corn... Impurities will fall onto the upper part of the screen plate 12 through the filter screen 14. The synchronous pulley 9 and synchronous belt between one of the rotating shafts 6 and the transmission rod 8 cause the transmission rod 8 to rotate, driving the cam 16 to rotate. The cam 16 and the mating block 15 cooperate, and the screen plate 12 is slidably connected to multiple through rods, causing the screen plate 12 to shake up and down. This shakes the corn that falls onto the screen plate 12, allowing the dust and impurities on the corn to be discharged through the filter screen 14 and the channel 17. The cleaned corn is discharged through the discharge port 11, achieving the effect of cleaning the corn and bringing convenience to people.
