[0017] 1. The present invention can disperse the grains through two inclined plates and further enable the grains to pass through the area blown by the first fan evenly and orderly. When the grains pass through, the air flow caused by the first fan can take away the dust in the grains. The dust blown away by the wind enters the dust collection box through the dust removal port.

[0018] 2. The present invention achieves the transportation of grains by allowing the grains falling from the screen plate to fall onto the conveyor belt, which is driven by the output shaft of the second motor and the transmission shaft rotates with the conveyor belt. When the grains are transported, when the grains pass through the bottom of the second fan, the second fan will drive air to blow toward the grains on the conveyor belt. At this time, a number of heating rods will generate heat, and the second fan will blow the heat toward the grains, which can further heat the grains. At the same time, the grains passing through the scraper will be turned over, thereby achieving the overall drying of the grains. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-6 As shown, a conveying device for grain processing with a grain processing dust removal component comprises a bottom plate 1, two support plates 3 are fixedly mounted on the top of the bottom plate 1, and dust removal boxes 301 are fixedly connected to the opposite surfaces of the two support plates 3;

[0029] It also includes a stone removal mechanism for removing stones from the grain;

[0030] The stone removal mechanism includes a sieve plate 6 and a collecting plate 7, and the sieve plate 6 and the collecting plate 7 are both rotatably installed on the opposite surfaces of the two support plates 3. The sieve plate 6 is located at the bottom of the feed port 31, and a plurality of stone-dropping holes are opened at the bottom of the sieve plate 6. A sliding rod 54 is rotatably connected to one side of the sieve plate 6, and a cam 52 is rotatably connected to one end of the sliding rod 54. A first motor 51 is fixedly connected to one side of the cam 52. A conveyor belt 84 is rotatably installed on the top of the bottom plate 1, and the conveyor belt 84 is located at the bottom of the sieve plate 6.

[0031] Furthermore, as shown in the figure, four supporting legs 2 are fixedly installed at the bottom of the base plate 1 , a first spring 21 is wound around the outer surface of the supporting leg 2 , and a stabilizing plate 22 is fixedly connected to the bottom of the supporting leg 2 .

[0032] When the grain is being dusted, it is still mixed with impurities such as heavy stones. It is difficult to completely remove the impurities in the grain by just blowing the grain with wind.

[0033] When the present invention is in use, firstly, the grain is put into the dust removal box 301. When the grain falls from the dust removal box 301, it will fall to the top of the sieve plate 6, and the cam 52 will be rotated by the output shaft of the first motor 51. The cam 52 touches one end of the slide bar 54. The further cam 52 can drive the cam 52 to slide, and cooperate with the second spring 55 to drive the slide bar 54 to reciprocate. In this process, the sieve plate 6 will move with the slide bar 54. Since the mass of the stone is greater than that of the grain, the stone is affected by the inertia of gravity to reach the end of the sieve plate 6 close to the first motor 51, and then falls to the top of the collecting plate 7 through the stone-falling hole, and finally falls through the collecting plate 7, while the grain falls from the other end of the sieve plate 6. Impurities with smaller mass or volume will fall directly from the middle of the sieve plate 6 to the top of the collecting plate 7, and fall together with the stone, thereby completing the cleaning of impurities in the grain.

[0034] Further, such as Figure 2As shown, a feed port 31 is provided on the top of the dust removal box 301, a discharge port 34 is provided on the bottom of the dust removal box 301, two inclined plates 32 are fixedly installed on the inner cavity of the dust removal box 301, and the two inclined plates 32 are not at the same height, and a plurality of buffer rods 33 are evenly and fixedly installed on the inner cavity of the dust removal box 301, a dust removal port 41 is provided on one side of the dust removal box 301, a first fan 4 is fixedly connected to one side of the dust removal box 301, and the first fan 4 passes through the inner cavity of the dust removal box 301, a filter is fixedly installed on the inner wall of the dust removal port 41, and a dust collecting box 42 is fixedly connected to the other side of the dust removal box 301, and the dust collecting box 42 passes through the inner cavity of the dust removal box 301.

[0035] When the present invention is in use, first, the grain is poured into the dust removal box 301 through the feed port 31, and then the grain passes through the two inclined plates 32 in turn. The setting of the two inclined plates 32 can slow down the flow rate of the grain, thereby preventing a large amount of grain from pouring in together and causing the dust in the grain to be unable to be completely cleaned. The first fan 4 blows air into the inner cavity of the dust removal box 301. At this time, the dust in the grain passing through the wind will be blown into the dust collection box 42. Due to the design of the dust removal port 41, no grain will enter the dust collection box 42. At the same time, the combination of a number of buffer rods 33 can slow down the time for the grain to fall, further increasing the time for the dust to be cleaned in the dust removal box 301.

[0036] Further, such as Figure 3 As shown, a vertical rod 5 is fixedly installed on the top of the bottom plate 1, the first motor 51 is fixedly installed on the top of the vertical rod 5, one end of the slide bar 54 is fixedly connected to a contact plate 53, and the cam 52 is rotatably installed on one side of the contact plate 53;

[0037] A limiting plate 56 is fixedly installed on the top of the bottom plate 1, and a first groove 57 is opened on the top of the limiting plate 56. The sliding rod 54 is slidably installed on the inner surface of the first groove 57. A second spring 55 is fixedly connected to one side of the limiting plate 56, and the second spring 55 is wound and installed on the outer surface of the sliding rod 54.

[0038] When the present invention is in use, the cam 52 is rotated by the output shaft of the first motor 51, and the outer surface of the cam 52 slides on one side of the contact plate 53. The cam 52 adjusts the contact point with the contact plate 53 to further make the slide bar 54 slide along the first groove 57. When the slide bar 54 slides, the slide bar 54 can move the screen plate 6.

[0039] Further, such as Figure 4As shown, two first limit blocks 62 and second limit blocks 72 are fixedly installed on the opposite surfaces of the two support plates 3, second grooves 61 are opened on both sides of the sieve plate 6, and the first limit blocks 62 are slidably installed on the inner surface of the second groove 61, and third grooves 71 are opened on both sides of the collecting plate 7, and the second limit blocks 72 are slidably installed on the inner surface of the third groove 71, and connecting pieces 73 are rotatably connected on both sides of the sieve plate 6 and the collecting plate 7, a connecting button 63 is fixedly installed on one side of the sieve plate 6, and the sliding rod 54 is rotatably installed on the inner surface of the connecting button 63.

[0040] When the present invention is in use, the slide rod 54 rotates on the inner surface of 63, and at the same time, the slide rod 54 can drive the sieve plate 6 to move. When the sieve plate 6 moves, the first limit block 62 slides on the inner surface of the second groove 61, and the collecting plate 7 is connected together through 63. Therefore, when the sieve plate 6 slides, the collecting plate 7 also slides. At this time, the grain on the top of the sieve plate 6 will be separated from the stones mixed in the grain, and at the same time, the smaller stones will first pass through the screen in the sieve plate 6 and fall onto the collecting plate 7.

[0041] Further, such as Figure 5 As shown, a waste collecting box 87 is fixedly installed on the top of the bottom plate 1, and the waste collecting box 87 is located at the bottom of the collecting plate 7. Four first support frames 8 are fixedly installed on the top of the bottom plate 1. The tops of the two first support frames 8 on the same side are fixedly connected with a transverse plate 81. The opposite surfaces of the two transverse plates 81 are rotatably connected with a transmission shaft 83. The conveyor belt 84 is rotatably installed on the outer surfaces of the two transmission shafts 83. A baffle 85 is fixedly installed on the outer surface of the conveyor belt 84. One end of the transmission shaft 83 is fixedly connected with a second motor 82. The second motor 82 is fixedly installed on one side of the transverse plate 81. A blanking plate 86 is fixedly installed on one side of the first support frame 8.

[0042] When the present invention is in use, the screened grain passes through one side of the screen plate 6 and falls to the top of the conveyor belt 84. The second motor 82 output shaft drives one of the transmission shafts 83 to rotate. The two transmission shafts 83 rotate together through the conveyor belt 84, thereby realizing the transportation of the grain. Finally, the grain falls from the conveyor belt 84 and is collected by the discharge plate 86. The stones and other impurities screened out from the grain will pass through the collection plate 7 and finally fall into the waste collection box 87.

[0043] Further, such as Figure 6As shown, the tops of the two horizontal plates 81 are commonly fixedly connected with a second support frame 9, the bottoms of the second support frame 9 are fixedly installed with two support sheets 92, the tops of the second support frame 9 are fixedly installed with a second fan 91, the opposite surfaces of the two support sheets 92 are commonly fixedly connected with a first connecting rod 93, the bottoms of the first connecting rod 93 are fixedly connected with two second connecting rods 94, the bottoms of the two second connecting rods 94 are commonly fixedly connected with a scraper blade 95, the scraper blade 95 is slidably installed on the top of the conveyor belt 84, and the opposite surfaces of the two support sheets 92 are fixedly installed with a plurality of heating rods 96.

[0044] When the present invention is in use, since the grain needs to be kept in a dry state for preservation, in order to avoid the collection of undried grain, the grain needs to be further dried. When the grain passes through the conveyor belt 84, the second fan 91 starts to blow air to the grain at the top of the conveyor belt 84. At this time, a number of heating rods 96 start to generate heat, and the second fan 91 can blow the high-temperature air generated by the heating rods 96 toward the grain to further dry the grain. When the grain is transported on the conveyor belt 84, the grain will pass through the scraper 95. The grain passing through the scraper 95 will be lifted by the scraper 95 and continue to move forward with the push of subsequent grain. The scraper 95 can turn the grain over to make the grain heated more evenly.

[0045] Working principle: First, the grain is poured into the dust removal box 301 through the feed port 31, and then the grain passes through the two inclined plates 32 in turn. The two inclined plates 32 can disperse the grain and further enable the grain to pass through the area blown by the first fan 4 evenly and orderly. When the grain passes through, the air flow caused by the first fan 4 can take away the dust in the grain, and the dust blown away by the wind enters the dust collection box 42 through the dust removal port 41. At the same time, after being blocked by the dust collection box 42, no grain will enter the dust collection box 42. Then the grain falls on the top of the screen plate 6. At this time, the output shaft of the first motor 51 carries the cam 52 The cam 52 rotates, and the outer surface of the cam 52 contacts the contact plate 53. The position of the contact plate 53 can be changed by the characteristics of the contact plate 53 itself. The contact plate 53 further slides with the slide bar 54 on the inner surface of the first groove 57. At the same time, the sieve plate 6 is driven by the slide bar 54 to slide on the first limit block 62 and the second limit block 72 on the inner surfaces of the second groove 61 and the third groove 71 respectively. At this time, the grain and stone on the top of the sieve plate 6 will be separated due to gravity, and the grain will fall from one side of the sieve plate 6, while the stone or smaller impurities will fall from the sieve holes and stone-falling holes on the sieve plate 6, fall on the top of the collecting plate 7, and finally fall into the waste collecting box 87.

[0046] The grain falling from the sieve plate 6 will fall onto the conveyor belt 84, and will be driven by the output shaft of the second motor 82. The transmission shaft 83 will rotate with the conveyor belt 84 to realize the transportation of the grain. When the grain is transported, when the grain passes through the bottom of the second fan 91, the second fan 91 will drive air to blow toward the grain on the conveyor belt 84. At this time, several heating rods 96 will heat up, and the second fan 91 will blow the heat toward the grain, which can further heat the grain. At the same time, the grain passing through the scraper 95 will be turned over, thereby realizing the overall drying of the grain.
