[0019] In order to better understand the present utility model, the following will Figures 1 to 4 be used to explain the embodiments of the present utility model in detail.
[0020] It should be noted that the "front, rear, left, right, up, down" directions described in the text are all based on the Figure 1 "front, rear, left, right, up, down" directions in
[0021] See Figures 1 to 4, same as the prior art, a corn thresher with a dust suppression structure of the present utility model also includes a main body 1. The main body 1 is provided with a threshing bin 2. An upward feeding hopper 3 and a downward bone outlet 4 are respectively arranged at both ends of the threshing bin 2. A threshing roller 5 is arranged in the threshing bin 2. A driving mechanism 6 for driving the threshing roller 5 is arranged on the main body 1. The driving mechanism 6 is a driving motor, which is connected to the threshing roller 5 through a belt. In addition, a dust suppression assembly 7 is arranged at one end of the threshing bin 2 of the corn thresher. The dust suppression assembly 7 includes a wind box 8 welded to the threshing bin 2. The threshing bin 2 is provided with an air outlet aligned with the wind box 8. Both ends of the wind box 8 are open and provided with vertical beams 9. Screen plates 10 covering the openings are arranged on both sides of each vertical beam 9. A shaft frame 11 corresponding to the vertical beams 9 at both ends is arranged in the wind box 8. A rotating shaft 12 is passed through the shaft frame 11 and one of the vertical beams 9 at one end. A fan 13 is arranged at one end of the rotating shaft 12, and the other end is fixedly connected to the threshing roller 5. Filter plates 14 (preferably primary air filter plates 10) are arranged on both sides of the shaft frame 11. A dust falling port 15 is arranged at the bottom of the wind box 8 near the threshing roller 5. A dust collection box 16 docked with the dust falling port 15 is detachably arranged at the bottom of the wind box 8.
[0022] When the driving mechanism 6 operates to drive the threshing roller 5 to rotate and work, the rotating shaft 12 connected to the threshing roller 5 also rotates coaxially, and drives the fan 13 on the rotating shaft 12 to rotate. Under the suction of the fan 13, the dust in the threshing bin 2 is sucked into the wind box 8 from the air outlet. During this period, the corn debris or larger bone debris doped in the dust is isolated by the screen plate 10. The remaining dust passes through the screen plate 10 and is intercepted by the filter plate 14. The dust that cannot pass through the filter plate 14 falls into the dust collection box 16 from the dust falling port 15 and is collected. When the threshing is completed, by controlling the driving mechanism 6 to reverse, the threshing roller 5 and the rotating shaft 12 are driven to reverse synchronously, and the fan 13 is used to blow air into the threshing bin 2 to blow away the adsorbed substances on the filter plate 14 and the screen plate 10, so as to realize the cleaning of the filter plate 14 and the screen plate 10.
[0023] In the preferred technical solution of this embodiment, considering that the filter plate 14 needs to be cleaned regularly to avoid blockage, as Figure 1 and Figure 2 shown, slots 17 adapted to the filter plate 14 are arranged on the front and rear sides of the vertical beam 9. An inspection opening is arranged at the top of the wind box 8, and a flip cover 18 cooperating with the inspection opening is arranged. A locking part 19 (preferably a lock) is arranged between the flip cover 18 and the wind box 8. By designing the filter plate 14 as a detachable structure, the filter plate 14 to be cleaned can be directly drawn out from the inspection opening after opening the flip cover 18, and reinserted into the slot 17 after cleaning, or a new filter plate 14 can be inserted into the slot 17 after replacement, so as to ensure the normal use of the filter plate 14.
[0024] In the preferred technical solution of this embodiment, in order to improve the smooth rotation of the rotating shaft 12, as Figure 2 shown in, a bearing 20 adapted to the rotating shaft 12 is provided on both the shaft frame 11 and the vertical beam 9 at one end thereof.
[0025] In the preferred technical solution of this embodiment, considering the harsh working environment of the bearing 20 in the air box 8, which needs to contact dust, a dust-proof cover (prior art) adapted to the end face of the bearing 20 is provided.
[0026] In the preferred technical solution of this embodiment, in order to facilitate the cleaning of the dust in the dust collection box 16, as Figure 2 、 Figure 3 and Figure 4 shown in, card slots 21 are provided at the bottom of the threshing bin 2 on both sides of the dust falling port 15, and sliding grooves 22 adapted to the card slots 21 are provided on the dust collection box 16. Through the cooperation of the card slots 21 and the sliding grooves 22, the dust collection box 16 is detachably connected to the air box 8.
[0027] In the preferred technical solution of this embodiment, in order to facilitate the loading and unloading of the dust collection box 16, as Figure 1 and Figure 4 shown in, a pulling handle 23 is provided on the dust collection box 16.
[0028] In the preferred technical solution of this embodiment, in order to prevent the suction force of the fan 13 from affecting the dust in the dust collection box 16, as Figure 2 shown in, a baffle 24 inclined downward is provided on one side of the inner wall of the dust collection box 16, and the baffle 24 is not connected to the other side of the inner wall.
