DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] like Figure 1-Figure 4 , Figure 6 and Figure 7As shown, a special component for separating grains from husks and dust comprises a main shell 1, a material slide 2 and a screen plate 4. The material slide 2 and the screen plate 4 are both obliquely arranged inside the main shell 1. The dense pores on the screen plate 4 can screen out dust and small debris mixed in the material, and can also screen out the husks mixed therein, so that the husks are exposed on the surface, which is convenient for sucking out the husks. A feed port 101 and an air intake port 102 are respectively provided on both sides of the top of the main shell 1, and a discharge port 103 is provided at the bottom. A drive shaft 6 is rotatably connected inside the main shell 1, and a plurality of groups of paddles 7 are fixedly connected to the outer wall of the drive shaft 6. The paddle plates 7 are located on the upper side of the screen plate 4. A baffle plate 8 is fixedly connected inside the main shell 1, and the baffle plate 8 is located on the upper side of the screen plate 4. An adjusting component 9 is provided inside the main shell 1, and the adjusting component 9 is connected to the baffle plate 8. The discharge port A material outlet plate 5 is provided at the bottom of 103, and an adjusting component 9 includes a fixing frame 901, which is fixedly connected to the inside of the main shell 1 and is arranged parallel to the screen plate 4. A screw rod 902 is rotatably connected to the inside of the fixing frame 901, and a slider 903 is threadedly connected to the outer wall of the screw rod 902. Both sides of the slider 903 are in contact with the inner wall of the fixing frame 901, and a baffle 8 is connected to the side wall of the slider 903. By rotating the screw rod 902, the screw rod 902 drives the slider 903 to move within the fixing frame 901, and the slider 903 drives the baffle 8 to move, thereby adjusting the distance between the baffle 8 and the paddle plate 7, so that the material sent by the paddle plate 7 can collide with the baffle 8 at different distances, thereby improving the convenience of adjusting the impact force. The baffle 8 is rotatably connected to the side wall of the slider 903, and the bottom of the baffle 8 is in contact with the top of the screen plate 4.

[0028] Through the setting of the rotation of the baffle 8, when the driving shaft 6 drives the paddle 7 to rotate to send the material on the screen plate 4, the material will push the baffle 8 to rotate while colliding and separating with the baffle 8. When the baffle 8 rotates and separates from the screen plate 4, the material after the collision can flow out through the gap between the baffle 8 and the screen plate 4, thereby fully ensuring the stability of the material's collision and outflow.

[0029] like Figure 2 and Figure 3 As shown, the inner wall of the material outlet plate 5 is fixedly connected with a plurality of sets of symmetrically arranged material diverter plates 3. The design of four material diverter plates 3 can prevent the material from being concentrated in one place when flowing out, thereby causing uneven distribution of the material in the color sorting equipment and affecting the overall output of the color sorting equipment.

[0030] like Figure 1 , Figure 3 and Figure 6As shown, a fixed plate 11 is fixedly connected to one side of the feed port 101, and a flow regulating plate 10 is arranged on one side of the fixed plate 11. Matching regulating grooves are provided on the fixed plate 11 and the flow regulating plate 10, and bolts 12 are arranged inside the regulating grooves to connect the fixed plate 11 and the flow regulating plate 10. Through the setting of the flow regulating plate 10, it is convenient to block the material directly entering the feed port 101, so that the material can enter the feed port 101 evenly. At the same time, the fixed plate 11 and the flow regulating plate 10 are loosened by tightening the bolts 12, and then the flow regulating plate 10 is moved to adjust the distance between the flow regulating plate 10 and the other side of the feed port 101, so that the amount of material falling onto the material slide 2 at the feed port 101 can be adjusted.

[0031] like Figure 1 and Figure 7 As shown, the material outlet plate 5 mentioned above is rotatably connected to a side wall of the discharge port 103, a connecting plate 13 is fixedly connected to the bottom of the main shell 1, and a push rod 14 is threadedly connected to the side wall of the connecting plate 13, and one end of the push rod 14 is against the side wall of the material outlet plate 5. By rotating the push rod 14, the push rod 14 moves and pushes the material outlet plate 5 to rotate, thereby adjusting the angle of the material outlet plate 5.

[0032] Embodiment 2:

[0033] like Figure 1 and Figure 5 As shown, a special component for separating grains from husks and dust includes a main shell 1, a material slide 2, and a screen plate 4. The material slide 2 and the screen plate 4 are both arranged obliquely inside the main shell 1. A feed port 101 and an air intake port 102 are respectively opened on both sides of the top of the main shell 1, and a discharge port 103 is opened at the bottom. A drive shaft 6 is rotatably connected inside the main shell 1, and a plurality of groups of paddles 7 are fixedly connected to the outer wall of the drive shaft 6. The paddles 7 are located on the upper side of the screen plate 4. A baffle 8 is fixedly connected inside the main shell 1. The baffle 8 is located on the upper side of the screen plate 4. The main shell 1 An adjusting component 9 is provided inside, which is connected to the baffle 8. A material outlet plate 5 is provided at the bottom of the discharge port 103. The adjusting component 9 includes a fixing frame 901, which is fixedly connected to the inside of the main shell 1. A screw rod 902 is rotatably connected to the inside of the fixing frame 901. A slider 903 is threadedly connected to the outer wall of the screw rod 902. Both sides of the slider 903 are attached to the inner wall of the fixing frame 901. The baffle 8 is connected to the side wall of the slider 903. The baffle 8 is fixedly connected to the side wall of the slider 903. A gap is left between the bottom of the baffle 8 and the screen plate 4.

[0034] Compared with the first embodiment, the baffle 8 is fixedly set on the screen plate 4, and the material is driven by the driving shaft 6 to drive the paddle 7 to rotate and hit the baffle 8, then falls downward onto the screen plate 4, and then flows downward through the gap between the screen plate 4 and the baffle 8, which can improve the material separation effect. At the same time, different from the first embodiment, the fixed baffle 8 will not cause the material to accumulate at the position of the baffle 8. The specific installation, setting and use of the baffle 8 can be installed and adjusted according to different material separation uses.

[0035] The working principle of the utility model is as follows: before the material enters the color sorting device, the material enters the feed port 101 on the top of the main shell 1 of the husk separation component through the conveying device, and at the same time, a suction fan is installed on the air inlet 102 on the main shell 1 to suck air into the main shell 1. Since the conveying device will have a wave phenomenon during operation, the material will fall unevenly. After entering the feed port 101, it is blocked by the flow regulating plate 10 to make the material fall evenly. Then the material falling from the flow regulating plate 10 falls onto the material slide 2 again. Through the guidance of the material slide 2, the material is further evenly fallen. Then the material flows from the material slide 2 to the screen plate 4, and the material is screened by the screen plate 4. The dense pores on the screen plate 4 can screen out the dust and small debris mixed in the material, and can also The husks mixed in the material can be screened out and exposed on the surface, so that the husks can be sucked out through the air intake port 102. At the same time, the driving shaft 6 is started, and the driving shaft 6 drives the paddle plate 7 to rotate. The direction of rotation of the paddle plate 7 is the same as the direction of material flow on the screen plate 4, so that the rotation of the paddle plate 7 beats the material and applies a driving force to the material, so that the material is knocked onto the baffle 8. The material collides with the baffle 8, which can shake out the husks and dust of the material from the material, thereby improving the effect of material classification and reducing the residue of husks and dust in the material. The material that hits the baffle 8 then falls downward onto the screen plate 4 and continues to flow, and then falls onto the material outlet plate 5 through the discharge port 103, and is diverted by the material diverter plate 3 on the material outlet plate 5, so that the material falls evenly in different collection devices, thereby improving the uniformity of collection.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
