[0032] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0033] In the prior art, a dust removal fan is often installed between the lifting system and the upper conveying system of the dryer to form a negative pressure to promote internal air flow and absorb light impurities such as dust. However, the effect of directly using negative pressure suction to remove dust from grains flowing along the wall is poor, and it can only remove light impurities on the surface, and it is difficult to fully handle impurities inside the grain flow layer.

[0034] In view of this, if Figure 1 , Figure 2 as well as Figure 3 As shown, on the one hand, the utility model provides a grain ash, impurities and husk air separation device, which includes a shell 3, a slide assembly 1 and a discharge adjustment assembly. The shell 3 is provided with a feed port 31 and a grain discharge port 32, and the grain discharge port 32 is located obliquely below the feed port 31. The slide assembly 1 is arranged between the feed port 31 and the grain discharge port 32 and includes a plurality of slides 11 arranged obliquely from top to bottom, and the plurality of slides 11 are inclined downward and toward the grain discharge port 32 to guide the material from the feed port 31 to the grain discharge port 32. The discharge adjustment assembly includes a stopper 21 and an adjustment structure 22, and a discharge channel is defined between the stopper 21 and the slide 11, and the adjustment structure 22 is connected to the stopper 21 and is used to change the position of the stopper 21 to adjust the size of the discharge channel.

[0035] When the grain ash, impurity and husk winnowing separation device is working, the grain moves downward through a plurality of slides 11 arranged obliquely from top to bottom, so that the impurities inside the grain flow move to the surface of the grain flow, so as to be easily sucked away and removed. In addition, when the incoming grain is relatively uneven, the impurities inside the thicker grain flow layer are not easy to be removed. At this time, by setting an adjustable discharge adjustment component, the incoming material can be made to fall evenly, avoiding the difficulty of removing the impurities inside when the grain flow layer is thick, and the dust removal effect can be flexibly controlled. In addition, the stopper 21 of the discharge adjustment component is matched with the slide 11 to form a discharge channel, which simplifies the structure of the device, makes the overall structure of the device simpler, more compact and reasonable, and has a lower manufacturing cost.

[0036] Among them, the structures of the housing 3, the slide assembly 1 and the discharge adjustment assembly can be various. The shape of the housing 3 can be square, trapezoidal or irregular, etc.; the slide 11 of the slide assembly 1 can be a flat plate with a smooth and complete surface, or a hollow plate, or a plate with a guide groove, etc.; the stopper 21 can be a baffle that can pivot and adjust the size of the discharge channel by rotating at different angles, or the stopper 21 can be a block that can move in translation and adjust the size of the discharge channel by translating to different positions, etc.; the adjustment structure 22 can be a manual drive structure or an electric drive structure, etc., and the present application is not limited thereto.

[0037] Alternatively, if Figure 2 and Figure 3 As shown, the housing 3 includes a bent plate at the top, a lower inclined plate at the bottom, and a side panel. The bent plate at the top includes a horizontal plate portion and an inclined plate portion connected to each other. The plate surfaces of the inclined plate portion and the lower inclined plate are arranged substantially parallel to each other and are arranged substantially parallel to the plate surface of the slide plate 11. The feed port 31 is opened on the horizontal plate portion, and the grain outlet 32 ​​is opened at the bottom of the housing 3 and is located below the inclined plate portion.

[0038] The slide assembly 1 is arranged in the shell cavity of the housing 3, and multiple slides 11 are arranged in an inclined manner from top to bottom, and the board surface of each slide 11 is arranged downward and inclined toward the grain outlet 32. The slide 11 has a smooth and complete board surface, which makes the flow of grain smoother. An air outlet channel is provided between any two adjacent slides 11, and in the vertical projection of any two adjacent slides 11, the lower end of the slide 11 located above overlaps the upper end of the slide 11 located below. Figure 3 As shown, the slides 11 are separated and staggered in the vertical direction, and the grains enter the feed port 31 and move downward through the slides 11 layer by layer. The enclosure plate of the housing 3 perpendicular to the side of the slide 11 and the uppermost slide 11 and the stopper 21 define a discharge channel.

[0039] Furthermore, the housing 3 is also provided with an air inlet 33 and an air outlet 34, wherein the air inlet 33 is located at the lower side of the slide 11, and the air outlet 34 is located at the upper side of the slide. The air outlet passage between any two adjacent slides 11 is connected between the air inlet 33 and the air outlet 34. In this way, the air flow moves upward from the bottom to separate impurities, and, without affecting the flow of grains, combined with the air flow of the air outlet passage, the impurities inside the grain flow can move to the surface, thereby removing impurities such as ash, debris, and shells in the grains step by step.

[0040] Furthermore, if Figure 2 and Figure 3 As shown, the air outlet 34 is opened on the inclined plate portion, and the air inlet 33 is arranged on the lower side of the uppermost slide plate 11 and above the uppermost air outlet channel. In this way, impurities inside the grain flow can be prevented from entering the air inlet 33.

[0041] Alternatively, if Figure 1 As shown, the grain ash, impurities and husk air separation device 10 also includes a fan 4, and the fan inlet of the fan 4 is connected to the air outlet 34, so that the ash, impurities, husks and other impurities in the grain can be sucked out through the fan 4.

[0042] In some specific embodiments, Figure 3 As shown, the stopper 21 includes a baffle, the upper end of the stopper 21 is rotatably connected to the housing 3, and the discharge channel is formed between the lower end of the stopper 21 and the slide 11. When the stopper 21 rotates, the size of the discharge channel can be adjusted, and the grain flow layer can be uniform without affecting the flow of grains, which is conducive to improving the dust removal and impurity removal effect.

[0043] In some specific embodiments, Figure 3 As shown, the discharge channel is defined between the stopper 21 and the uppermost slide 11, and the uppermost slide 11 is longer than the lower slide 11. In this way, when the stopper 21 rotates, the stopper 21 and the uppermost slide 11 can always cooperate with each other.

[0044] Furthermore, if Figure 2 and Figure 3 As shown, the adjustment structure 22 includes an adjustment rod 221 fixedly connected to the stopper 21, and a counterweight 222 is provided on the adjustment rod 221. The counterweight 222 is movably connected to the adjustment rod 221 and can adjust the connection position along the axial direction of the adjustment rod 221. The discharge adjustment assembly is located below the feed port 31, and the stopper 21 can rotate around the axis to control the flow of grain and make the incoming material fall evenly. The adjustment rod 221 is provided with a counterweight 222, and the opening and closing degree of the stopper 21 is adjusted by adjusting the different axial connection positions of the counterweight 222 on the adjustment rod 221, so as to flexibly adjust the grain flow rate.

[0045] When the grain ash, impurities and husk winnowing separation device is working, under the influence of the airflow passing through the air outlet channel between the slides 11 and the difference in specific gravity, the impurities inside the grain flow move to the surface of the grain flow and are sucked away and removed. The discharge adjustment component can make the incoming material fall evenly, avoiding the difficulty of removing the impurities inside when the grain flow layer is thick. The overall adjustment of the discharge adjustment component is convenient, and the dust removal effect can be flexibly controlled.

[0046] The second aspect of the present application further provides a grain dryer, which includes the grain ash, impurities and shells wind separation device. Since the grain dryer includes the grain ash, impurities and shells wind separation device, it also has all the technical effects brought by the grain ash, impurities and shells wind separation device, so it will not be repeated.

[0047] Optionally, the grain dryer further comprises a dust removal duct 5 and an elevator 6, wherein the dust removal duct 5 is connected to the fan outlet of the fan 4 to discharge dust and impurities. The discharge portion of the elevator 6 is arranged on the feed port 31 to feed the feed port 31.

[0048] Specifically, during the grain circulation process, the grain enters the feed port 31 from the elevator 6, and the stopper 21 controls the thickness of the grain flow layer to prevent impurities inside the grain flow from being difficult to remove when the flow rate is large. When the grain flows downward, it gradually flows through the slides 11 that are vertically separated and staggered from each other. Dust and surface impurities are aroused and sucked away by the fan 4, and enter the ash room through the dust removal pipe 5. Under the effect of specific gravity difference and air selection, the impurities inside the grain flow gradually move to the surface and are finally removed by the fan 4. When there are more impurities in the grain, the counterweight block 222 can be adjusted outward to make the discharge channel between the stopper 21 and the slide 11 more closed, and the grain falls in a thinner layer, thereby enhancing the dust removal effect of the device. After multiple cycles, most of the chaff, impurities and dust are removed, ensuring the quality of the dried grain while reducing the dust in the working environment of the grain dryer.

[0049] It should be noted that the structures of the hoist 6, the fan 4, etc. are well known to those skilled in the art, and do not belong to the core improvement part of the present application, so they will not be described here in detail.

[0050] In summary, the grain ash, impurity and shell winnowing separation device and grain dryer of the utility model adopt a top dust removal system structure and a multi-stage smooth slide plate, which is conducive to the flow of grains. In addition, by adopting a grain baffle with a counterweight block, the thickness of the grain flow layer can be flexibly adjusted to facilitate the removal of impurities inside the grain flow layer, and the top negative pressure air suction port avoids blockage and grain loss.
