[0021] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.
[0022] like Figure 1 As shown, the present invention provides a dry intelligent sorting bin, comprising a vibration frame 1, a vibration sorting bin 2, and a vibration source 3. The vibration source 3 is mounted on the vibration frame 1. The upper end of the vibration frame 1 is elastically connected to the vibration sorting bin 2. The bottom surface of the vibration sorting bin 2 is concave, with a feed port at one end and a discharge port at the other end. The discharge ports are divided into a first discharge port 4 and a second discharge port 5. The first discharge port 4 is located above the second discharge port 5 for discharging grain, while the second discharge port 5 is used to discharge impurities such as sand and gravel. When the vibration source 3 is activated, it drives the vibration frame 1 to vibrate, thereby driving the vibration sorting bin 2 to vibrate. The material entering the vibration sorting bin 2 from the feed port moves up and down in the vibration sorting bin 2, with heavy impurities moving downward and light grain moving upward, forming an upper grain layer and a lower impurity layer. Finally, the grain is discharged from the first discharge port 4 and the heavy impurities are discharged from the second discharge port 5.
[0023] Preferably, the vibration source 3 is a vibration motor.
[0024] like Figure 2 and Figure 3 As shown, in some preferred embodiments, a vibration-damping spring 6 and a shear spring 7 are further included. The lower end of the vibration frame 1 is fixedly connected to the upper end of the vibration-damping spring 6, and the lower end of the vibration-damping spring 6 is connected to the ground foundation or the plate foundation; the upper end of the vibration frame 1 is connected to one end of the shear spring 7, and the other end of the shear spring 7 is connected to the outer wall of the vibration sorting bin 2, forming a dual-proton vibration system.
[0025] In some preferred embodiments, the vibrating sorting bin is a boat-shaped structure, and a baffle is fixed to the inner wall of the vibrating sorting bin 2 between the first discharge port 4 and the second discharge port 5 to spatially separate the first discharge port 4 and the second discharge port 5 and to separate and discharge the materials. The baffle includes a fixed baffle and an adjustable baffle 10. The fixed baffle is formed by welding a horizontal plate 8 and an inclined plate 9, the horizontal plate 8 of the fixed baffle is fixed near the first discharge port 4, and the inclined plate 9 is suspended at the upper portion of the vibrating sorting bin 2. The inclined plate 9 is used to prevent impurities from being mixed in the grain and being discharged from the first discharge port 4. The materials that reach the inclined plate 9 will slide down without stopping, so that the mixed impurities fall into the sand layer again. The upper end of the adjustable baffle 10 is in abutment with the inclined plate 9. When the adjustable baffle 10 is in the lowest position, the upper end of the adjustable baffle 10 is still in abutment with the inclined plate 9, so that no gap is formed between the inclined plate 9 and the adjustable baffle 10 for the materials to pass through. The two sides of the adjustable baffle 10 are slidably connected to the side walls of the vibrating sorting bin 2. By changing the height position of the adjustable baffle, the thickness of the material layer is adjusted, and the sorting efficiency is controlled.
[0026] Preferably, as shown in Figure 4 the side wall of the vibrating sorting bin 2 is provided with a vertical long slot 201, the lower sides of the adjustable baffle 10 are respectively fixed with symmetrically arranged screw rods 101, the two screw rods 101 are respectively inserted into the vertical long slot 201 on the corresponding side, and the exposed ends of the screw rods 101 are fastened by bolts to fix the screw rods 101 and the adjustable baffle 10 at a certain height position. The lower ends of the two side surfaces of the adjustable baffle 10 respectively extend fixedly connected leakage prevention side baffles 102, the length of the leakage prevention side baffles 102 is greater than the length of the vertical long slot 201, and the width of the leakage prevention side baffles 102 is greater than the width of the vertical long slot 201. When the adjustable baffle 10 is lifted along the vertical long slot 201, the leakage prevention side baffles 102 block the vertical long slot 201 below the screw rods 101 to prevent material leakage.
[0027] As shown in Figure 5 and Figure 6 the utility model also provides a kind of dry type intelligent sorting system, and the dry type intelligent sorting system includes primary screening structure and re-screening structure, and the primary screening structure includes vibrating screen 11, screen above material conveying belt 12 and screen below material conveying belt 13, and the upper layer of vibrating screen 11 is provided with screen above material collecting groove, and the outlet of screen above material collecting groove is screen above material conveying belt 12 for conveying large particle size impurities below;The lower layer of vibrating screen 11 is provided with screen below material collecting groove, and the outlet of screen below material collecting groove is screen below material conveying belt 13 for conveying grain and smaller particle size impurities below.
[0028] The re-screening structure includes any one of the foregoing embodiments of the dry type intelligent sorting bin, grain conveying belt 14 and impurity conveying belt 15, the first discharge port of vibrating sorting bin 2 is aligned with grain conveying belt 14 below, and the second discharge port is impurity conveying belt 15 below.
[0029] Working process:
[0030] The impurity-mixed grain (such as rice, cereal, beans, etc.) is transported to the vibrating screen 11 for primary screening. During the primary screening, the large-particle impurities stay on the screen and slide into the screen-top collecting chute, and are transported out by the screen-top material conveying belt 12. The grain and small-particle impurities fall into the screen-under part and are collected in the screen-under collecting chute, and are transported to the vibrating sorting bin 2 by the screen-under material conveying belt 13. The vibrating sorting bin 2 vibrates under the action of the vibrating motor, driving the material in the bin to move up and down. The impurities with heavy mass and small particle size gradually gather in the lower part of the vibrating sorting bin 2, forming a sandstone layer. The grain with light mass and uniform particle size gathers in the upper part of the vibrating sorting bin 2, forming a grain layer, as shown in Fig. 2. Figure 7 The upper layer of the sandstone layer is blocked by the adjusting baffle 10. The layer where the inclined plate 9 above the adjusting baffle 10 is located is the grain layer. Under the action of vibration, the grain layer moves along the inclined plate 9 to the first discharge port 4, and is finally discharged from the first discharge port 4 and falls into the grain conveying belt 14. Due to the action of the inclined plate 9, even if the impurities are carried upward by the grain, they will slide along the inclined plate 9 at the inclined plate 9 and fall into the sandstone layer again. The sandstone layer moves from below the adjusting baffle 10 to the second discharge port 5 and is discharged, falling into the impurity conveying belt 15, to complete the dry grain sorting operation.
[0031] Finally, it should be noted that: the above-mentioned is only the preferred embodiment of the present application, of course, the person skilled in the art can modify and change the present application, provided that these modifications and changes belong to the scope of the present application claims and its equivalent technology, should be considered as the protection scope of the present application.
