Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a rough grain air separation device which can automatically load and clean the grains based on automation. Background Art

[0002] When brown rice is processed in rural areas, after processing, there is usually a lot of rice husks, rice straw branches or sand and gravel mixed in the rice. Therefore, before the brown rice is stored in the warehouse, it needs to be separated by wind to remove impurities.

[0003] The existing wind separation device usually manually introduces the brown rice into the top hopper bin, and then turns on the blower. During the falling process of the grain, the wind force causes the rice or other impurities to be blown to different distances according to their weight. By setting different drop-in ports inside the wind separation device, the rice and impurities are discharged through different drop-in ports, achieving the effect of screening and removing impurities. However, there are the following disadvantages:

[0004] 1) Loading is troublesome. The loading hopper is usually set at the top of the air separation device, so the operator needs to transport the rice to a high place for loading, which is very troublesome;

[0005] 2) The air separation is not thorough. Since the air source is only the blower, and it is usually blown horizontally, the movement trajectory of the debris is in the horizontal parabola direction. Due to the limited overall volume of the air separation equipment, the existing air separation equipment often does not screen cleanly. After air separation, there are often still a small amount of debris in the finished grain. When the grain is processed, it often contains fine sand and gravel. The existing air separation device has a poor air separation effect on sand and gravel, and screening is often still required after processing, which greatly increases the labor cost.

[0006] 3) It causes serious air pollution. During air separation, due to the rapid air flow inside the air separation equipment, a large amount of dust will be blown into the air. At the same time, the small leaves blown by the wind will also fly everywhere, causing serious air pollution and causing great trouble for cleaning after air separation. Summary of the invention

[0019] Beneficial effects:

[0020] 1. The rice roughage air separation equipment based on automation and capable of automatic loading and cleaning blows out airflow obliquely upward through the air outlet. Under the action of the oblique upward airflow, the rice husks or branches mixed with the rice roughage are blown by an oblique upward airflow, so that the rice husks make an oblique upward parabolic motion, thereby effectively allowing the rice husks and other debris to fly farther, effectively ensuring the separation effect. After the separation is completed, the rice roughage falls into the finished product cavity, and the rice roughage inside the finished product cavity is discharged through the discharge block and the first discharge conduit, and the staff completes the collection work outside the first discharge conduit. The separated debris falls into the debris cavity after separation, completing the collection of the debris. When the rice roughage passes through the guide screen, the sand and gravel mixed inside the rice roughage falls into the sand storage cavity under the action of the guide screen, so that when the rice roughage is air-separated, the sand and gravel inside the rice roughage can be screened simultaneously, further improving the screening effect of the rice roughage.

[0021] 2. The automatic feeding and cleaning rice roughness winnowing equipment based on automation drives the spiral blade to rotate through the feeding motor, and the spiral blade drives the rice roughness to move upward inside the guide pipe and enter the feeding cavity through the guide port. This avoids the staff from carrying the rice roughness to a high place for feeding, effectively reduces the difficulty of feeding, and achieves the effect of automatic feeding.

[0022] 3. The automatic grain roughness air separation equipment that can automatically load and clean the grains can control the falling direction of the finished grain roughness inside the finished product cavity by controlling the baffle plate, so as to achieve the effect of controlling the discharge direction of the grain roughness. When the baffle plate is located on the feed port side of the first discharge duct, the finished product cavity is connected with the second discharge duct, and the finished product cavity falls into the interior of the pouring box through the second discharge duct, thereby achieving the effect of automatic cycle for the grain roughness air separation, avoiding the trouble of manual secondary transportation of the grain roughness, and effectively improving the screening effect of the device.

[0023] 4. The grain roughness air separation equipment which can automatically load and clean based on automation, the turbine fan attracts the internal gas of the suction chamber through the air inlet pipe, forms a negative pressure inside the suction chamber, and the suction chamber absorbs the gas inside the debris chamber through the suction dust isolation net, so that the debris chamber automatically absorbs the debris inside the main shell, and the absorbed debris falls into the debris net bag, which is convenient for cleaning the debris after the air separation is completed. The turbine fan completes the circulation of the internal gas of the main shell, and at the same time makes the dust and debris fall into the debris net bag to complete the collection of dust and prevent the dust from drifting into the air, which not only effectively improves the air separation effect, but also reduces the pollution to the air.

DETAILED DESCRIPTION

[0032] 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.

[0033] Embodiment 1

[0034] See also Figure 1-5 , a rough grain air separation device based on automation and capable of automatic loading and cleaning, comprises a main shell 1, a feeding cavity 2 is opened on the top of the main shell 1, a material guide screen 3 is fixedly connected inside the main shell 1, a wind separation component 4 is fixedly connected inside the main shell 1, the wind separation component 4 is located on one side of the lower surface of the material guide screen 3, a material pouring box 5 is fixedly connected to the outside of the main shell 1, a material guide pipe 6 is fixedly connected to the outside of the main shell 1, a material guide port 61 is fixedly connected to the outside of the material guide pipe 6, a spiral blade 62 is rotatably connected to the inside of the material guide pipe 6, a feeding motor 63 is fixedly connected to the top of the material guide pipe 6, the bottom of the material guide pipe 6 is located inside the material pouring box 5, and the material guide port 61 is located above the feeding cavity 2.

[0035] The outside of the air selection component 4 is fixedly connected with an inclined protrusion 41, and an air outlet 42 is opened on one side of the upper inclined surface of the inclined protrusion 41. The inside of the air outlet 42 is fixedly connected with an auxiliary air outlet 43 and a main air outlet 44. The outside of the auxiliary air outlet 43 is fixedly connected with an auxiliary air duct 45, and the outside of the main air outlet 44 is fixedly connected with a main air duct 46. The outside of the auxiliary air duct 45 is fixedly connected with an air inlet chamber 47, and the outer side surface of the air inlet chamber 47 is fixedly connected with an air inlet dust screening net 471, and the outside of the main air duct 46 is fixedly connected with the main air duct 48.

[0036] A sand storage chamber 7, a finished product chamber 8 and a debris chamber 9 are provided inside the main shell 1. The sand storage chamber 7 is located below the vertical projection of the material guide screen 3, the finished product chamber 8 is located below the sand storage chamber 7, and the feed port of the finished product chamber 8 is located on the lower side of the upper surface of the material guide screen 3. A discharge block 10 is fixedly connected to the outside of the finished product chamber 8, and a first discharge conduit 101 is fixedly connected to the outside of the discharge block 10.

[0037] The bottom of the main housing 1 is fixedly connected with a turbine fan 11 , the outside of the turbine fan 11 is fixedly connected with an air outlet pipe 112 , and the air outlet pipe 112 is fixedly connected to the main air duct 46 .

[0038] The guide screen 3 is tilted inside the main housing 1, and a guide bump 31 is fixedly connected to the upper surface of the guide screen 3. The angle between the guide screen 3 and the horizontal plane is 60° to 80°. The guide screen 3 is located below the feed cavity 2, and the discharge port of the feed cavity 2 is located on one side of the upper surface of the guide screen 3. The grains in the feed cavity 2 directly fall into the upper side of the guide screen 3 through the discharge port of the feed cavity 2, and slide downward along the upper surface of the guide screen 3. By setting the angle to 60° to 80°, it is convenient for the material to fall from the guide screen 3. When the grains pass through the guide bump 31, the grains jump outward due to inertia, thereby achieving the effect of automatically turning over the grains.

[0039] Among them, the inclined protrusion 41 is located on one side of the material guide screen 3 of the air selection component 4, and there are several inclined protrusions 41. The distance between each two inclined protrusions 41 is 8 to 80 cm. The air outlets 42 opened by several inclined protrusions 41 are fixedly connected through the auxiliary air outlets 43 and the auxiliary air guide ducts 45. The air outlets 42 opened by several inclined protrusions 41 are fixedly connected through the main air outlets 44 and the main air guide duct 46. The auxiliary air guide duct 45 is connected to the outside through the air inlet chamber 47 and the air inlet dust screening net 471, and the main air duct 46 is connected to the air outlet part of the turbine fan 11 through the air outlet duct 112. When taking in air, the turbine fan 11 generates wind and enters the main air duct 46 through the outlet pipe 112 and the main air duct 48. The wind inside the main air duct 46 enters the air outlet 42 through the main air port 44, and the wind is blown out obliquely upward through the air outlet 42. According to Bernoulli's principle, the air flow rate of the main air port 44 of the air outlet 42 is greater than the flow rate of the auxiliary air port 43, and the pressure of the auxiliary air port 43 is greater than the internal pressure of the air outlet 42. Since the auxiliary air port 43 is connected to the outside through the auxiliary air duct 45 and the air inlet chamber 47, the external air flow flows into the air outlet 42 through the auxiliary air port 43 and flows out through the air outlet 42. Therefore, the total flowing air at the air outlet 42 is the wind generated by the turbine fan 11 and the wind flowing into the auxiliary air port 43, thereby effectively increasing the wind blowing effect and ensuring the air selection effect under the same power. At the same time, the air flow is guided by the air outlet duct 112, the main air duct 46 and the main air duct 48, and the turbine fan 11 is arranged outside the main shell 1 to reduce the impact of dust on the turbine fan 11, thereby effectively improving the use effect and service life of the turbine fan 11.

[0040] Specific working process and principle: When working, the rice dregs are directly poured into the pouring box 5, and the feeding motor 63 and the turbo fan 11 are started at the same time. The feeding motor 63 drives the spiral blade 62 to rotate, and the spiral blade 62 drives the rice dregs to move upward inside the guide pipe 6 and enter the feeding cavity 2 through the guide port 61. It avoids the staff from carrying the rice dregs to a high place for feeding, effectively reduces the difficulty of feeding, and achieves the effect of automatic feeding.

[0041] The grain roughness inside the feed chamber 2 falls onto the upper surface of the material guide screen 3 through the discharge port at the bottom, and slides downward under the action of its own gravity. When passing through the material guide protrusion 31, the grain roughness at the bottom passes through the material guide protrusion 31, and is affected by the slope of the material guide protrusion 31 and the falling inertia of the grain roughness, so that the grain roughness has an oblique outward force, while the grain roughness at the top falls relatively smoothly, and its falling direction is synchronized with the inclination angle of the material guide screen 3, so that the grain roughness flips over after passing through the material guide protrusion 31.

[0042] When the rice husks fall along the guide screen 3, the turbine fan 11 generates airflow, which passes through the outlet pipe 112, the main air duct 48 and the main air duct 46, and the airflow passes through the main air port 44 and the outlet port 42, and the airflow is blown out obliquely upward through the outlet port 42. Under the blowing action of the oblique upward airflow, the rice husks or branches mixed with the rice husks are blown by an oblique upward airflow, so that the rice husks make an oblique upward parabolic motion, so that the rice husks and other debris can fly farther, effectively ensuring the separation effect. After the separation is completed, the rice husks fall into the finished product chamber 8, and the rice husks inside the finished product chamber 8 are discharged through the discharge block 10 and the first discharge conduit 101, and the staff completes the collection work outside the first discharge conduit 101. The separated debris falls into the debris chamber 9 after separation, completing the collection of the debris.

[0043] When the grain shavings pass through the material guide screen 3, the sand and gravel mixed inside the grain shavings fall into the sand storage chamber 7 under the action of the material guide screen 3, so that when the grain shavings are winnowed, the sand and gravel inside the grain shavings can be screened simultaneously, further improving the screening effect of the grain shavings.

[0044] Embodiment 2

[0045] See also Figure 7 On the basis of the first embodiment, the outside of the discharging block 10 is further connected with a second discharging conduit 102 , and the inside of the discharging block 10 is slidably connected with a baffle plate 103 .

[0046] Among them, the rotational sliding angle of the baffle plate 103 is 270°, and the rotational sliding position of the baffle plate 103 is the feed port position of the discharge block 10, the feed port position of the first discharge conduit 101, and the feed port position of the second discharge conduit 102. The discharge port of the second discharge conduit 102 is located above the pouring box 5.

[0047] When the finished grains in the finished product cavity 8 are discharged through the discharge block 10, it is convenient to control the falling direction of the finished grains in the finished product cavity 8 by controlling the baffle plate 103. When the baffle plate 103 is located on the side of the feed port of the discharge block 10, the finished product cavity 8 is closed, so that the finished grains are temporarily stored in the finished product cavity 8. When the baffle plate 103 is located on the side of the feed port of the second discharge conduit 102, the finished product cavity 8 is connected with the first discharge conduit 101, and the finished product cavity 8 is led out of the main shell 1 through the first discharge conduit 101. When the baffle plate 103 is located on the side of the feed port of the first discharge conduit 101, the finished product cavity 8 is connected with the second discharge conduit 102, and the finished product cavity 8 falls into the inside of the pouring box 5 through the second discharge conduit 102, thereby achieving the effect of automatic circulation to winnow the grains, avoiding the trouble of manual secondary conveying of the grains, and effectively improving the screening effect of the device.

[0048] Embodiment 3

[0049] See also Figure 6 On the basis of the second embodiment, a suction dust-proof net 91 is fixedly connected to the bottom of the debris chamber 9, a suction chamber 92 is fixedly connected to the bottom of the debris chamber 9, a debris net bag 93 is clamped inside the debris chamber 9, an air inlet pipe 111 is fixedly connected to the outside of the suction chamber 92, and the air inlet pipe 111 is fixedly connected to the outside of the turbine fan 11.

[0050] Since the air inlet pipe 111 of the turbine fan 11 is connected to the air suction chamber 92, when the turbine fan 11 is working, the turbine fan 11 attracts the gas inside the air suction chamber 92 through the air inlet pipe 111, and a negative pressure is formed inside the air suction chamber 92. The air suction chamber 92 absorbs the gas inside the debris chamber 9 through the air suction dust isolation net 91, so that the debris chamber 9 automatically absorbs the debris inside the main shell 1, and the absorbed debris falls into the debris net bag 93, which is convenient for cleaning the debris after the air selection is completed. The turbine fan 11 completes the circulation of the gas inside the main shell 1, and at the same time makes the dust and miscellaneous leaves fall into the debris net bag 93, completes the collection of dust, and prevents the dust from floating into the air, which not only effectively improves the air selection effect, but also reduces the pollution to the air.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
