Referring to fig. 1 and 2, fig. 1 is a schematic diagram of an overall cross-sectional structure of a corn thresher with dust removal function according to an embodiment of the present application, and fig. 2 is an enlarged view of fig. 1 at a. The corn thresher 100 with the dust removal function comprises a threshing box 110, a dust removal box 120 and a trash storage box 130, wherein the trash storage box 130 and the dust removal box 120 are communicated with the threshing box 110, the dust removal box 120 and the trash storage box 130 are respectively three main functional areas, impurities and dust in corn particles are adsorbed by the dust removal box 120 after corn is threshed in the threshing box 110, and the residual corn cobs after corn threshing are sent into the trash storage box 130 to be accommodated. The top of the threshing box 110 is provided with a feed inlet 111, corn to be threshed is fed in from the feed inlet 111, a threshing device is arranged in the threshing box 110, the threshing device is used for threshing corn and comprises two threshing rollers 112 which are arranged side by side, the threshing device is positioned at the bottom of the feed inlet 111, the corn falls on the threshing rollers 112 after entering from the feed inlet 111, and the two threshing rollers 112 impact the corn and drive the corn to rub against each other in the rotating process so as to realize threshing of corncob and corn particles. The threshing roller 112 is prior art and is not the core of the claimed utility model and will not be described in detail herein. The bottom of the threshing roller 112 is provided with a drainage screen 113, the drainage screen 113 is provided with meshes, and the aperture of the meshes is larger than the diameter of corn particles and impurities and smaller than the diameter of corncobs. The drainage screen 113 is obliquely arranged, corn particles and corncobs which are separated from the threshing roller 112 fall onto the drainage screen 113 together, slide along the drainage screen 113 under the action of dead weight, penetrate out of the threshing box 110 from the lower end of the drainage screen 113 and extend into the impurity storage box 130, in the sliding process, the corn particles pass through meshes on the drainage screen 113 and fall onto the drainage plate 114, and the corncobs enter the impurity storage box 130 to be accommodated. The shell of the threshing box 110 at the bottom of the drainage screen 113 is inclined to form the drainage plate 114, the inclination angle of the drainage plate 114 corresponds to that of the drainage screen 113, the bottom of the threshing box 110 is contracted to form the blanking channel 115, the drainage plate 114 and the blanking channel 115 are formed by bending the shell wall of the threshing box 110, the whole structure of the equipment is compact, and the integrated equipment enables the failure rate of the equipment to be lower. The corn particles, impurities and dust falling on the drainage plate 114 slide on the drainage plate 114 and fall into the blanking channel 115, the side wall of the blanking channel 115 is communicated with the dust collection box 120, the dust collection box 120 is internally provided with a dust collection device 140, the inlet of the dust collection device 140 is communicated with the side wall of the blanking channel 115, the dust collection device 140 generates negative pressure, the connection part of the blanking channel 115 and the dust collection device 140 is provided with a first filter screen 121, the mesh of the first filter screen 121 is smaller than that of the corn particles and larger than the diameters of the impurities and dust, when the corn particles, the impurities and the dust pass through the blanking channel 115, the dust collection device 140 generates negative pressure to suck the dust and the impurities into the dust collection box 120 from the blanking channel 115 by adjusting the power of the dust collection device 140 to match the working environment, and the corn particles are blocked by the first filter screen 121 and further fall from the blanking channel 115, and finally can be collected from the bottom end of the blanking channel 115.

As can be seen from the above, in the embodiment of the present application, by providing a drainage net in the threshing box 110, the corn cob, the corn particles and the dust impurities are separated, and the separated corn cob enters the impurity storage box 130 to be stored. By arranging the drainage plate 114 to introduce corn particles and dust impurities into the blanking channel 115, the blanking channel 115 is narrower, and the dust and impurities can be quickly sucked out by the dust suction device 140 in the falling process of the corn particles from the blanking channel 115, so that the dust and impurities are prevented from being discharged into the air to cause environmental pollution.

In some embodiments, the dust collection device 140 includes a partition 141, the partition 141 divides the dust collection box 120 into a dust collection cavity 122 and a filter cavity 123, a dust collection fan 142 is disposed at the partition 141, an air inlet end of the dust collection fan 142 is located in the dust collection cavity 122, an air outlet end of the dust collection fan 142 is located in the filter cavity 123, an air outlet 123a is formed in an outer wall of the filter cavity 123, a dust collection bag 122a is disposed in the dust collection cavity 122, one end of the dust collection bag 122a is communicated with a hose 122b, and the other end of the hose 122b is communicated with the blanking channel 115.

In this embodiment, the dust collection device 140 specifically works by starting the dust collection fan 142, and after the dust collection fan 142 rotates, negative pressure is formed in the dust collection cavity 122, so that the dust collection device can generate adsorption force to impurities and dust in the discharging channel 115, the impurities and the dust enter the hose 122b and further enter the dust bag 122a to be blocked and received by the dust bag 122a, and the air can pass through the dust bag 122a and be further discharged from the air outlet 123 a.

In some embodiments, a filtering channel 143 is disposed in the middle of the partition 141, two ends of the filtering channel 143 extend to the filtering cavity 123 and the dust removing cavity 122 respectively, the dust suction fan 142 is fixed in the filtering channel 143, a second filter screen 144 is disposed at a port of one end of the filtering channel 143, and the other end of the second filter screen 144 is communicated with the dust bag 122a.

In this embodiment, through setting up the filter passageway 143 so that the air that sees through dust bag 122a and some dust can only get into filter chamber 123 through filter passageway 143, because in the concrete course of working, dust bag 122a can not receive the dust completely, and this part dust can be filtered by second filter screen 144 when getting into filter passageway 143, and the air that sees through dust bag 122a can cool down dust absorption fan 142's motor in the in-process that filter passageway 143 was led through.

In some embodiments, a third filter screen 123b is disposed at the air outlet 123 a. By providing the third filter screen 123b as a third filter layer, dust is prevented from being discharged into the air after passing through the dust bag 122a and the second filter screen 144.
