DETAILED DESCRIPTION

[0019] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Embodiment 1: The present invention provides a technical solution: Referring to Figure 1 - Figure 6 The present invention discloses a rice feeding and lifting device, comprising a suction pipe 1 and a storage barrel 2, wherein the discharge end of the suction pipe 1 is arranged at the outer peripheral side of the storage barrel 2 and is connected and installed with the storage barrel 2; Also includes: The suction assembly 3 includes an air pump 31 fixedly mounted on the top side of the storage barrel 2, and the air inlet end of the air pump 31 is fixedly penetrated through the barrel wall of the storage barrel 2, a filtering mechanism 32 is provided on the storage barrel 2, a dust removal pipe 33 is provided at the axial position in the suction pipe 1, a partition plate 34 is fixedly wound and installed on the outer peripheral side of the dust removal pipe 33 in a spiral shape, and the partition plate 34 is fixedly connected to the inner wall of the suction pipe 1, the dust removal pipe 33 is mainly composed of a filter pipe 331, a soft pipe 332 and a hard pipe 333, and the two ends of the soft pipe 332 are connected and installed with the discharge end of the filter pipe 331 and the feed end of the hard pipe 333 respectively, the discharge end of the hard pipe 333 is L-shaped and inserted into the storage barrel 2, and the feed end of the hard pipe 333 is fixedly connected to the inner wall of the suction pipe 1 through a plurality of connecting rods; A discharge assembly 4, which is disposed at the bottom end of the storage barrel 2, and the discharge assembly 4 continuously discharges the rice in the storage barrel 2; The scattering component 5 includes a plurality of brushes 51 , which are fixedly mounted on the inner wall of the feeding end of the suction pipe 1 , and the brushes 51 are located between the partition plate 34 and the dust removal pipe 33 and the inner wall of the suction pipe 1 , and a scattering mechanism 52 is provided in the storage barrel 2 .

[0021] In this embodiment, it should be noted that the above-mentioned suction pipe 1, filter pipe 331 and partition plate 34 are all made of soft materials, such as soft plastic or rubber. Figure 5 As shown, the connecting rod is located inside the wall of the storage barrel 2; When the improved rice feeding and lifting device is used, the air pump 31 starts to extract the gas in the storage barrel 2 at a uniform speed, so that a negative pressure chamber is continuously formed in the storage barrel 2, and the gas in the hard tube 333, the soft tube 332 and the discharge port of the suction pipe 1 continuously flows into the storage barrel 2 to replenish the gas lost in the storage barrel 2, thereby continuously forming a negative pressure state in the soft tube 332, the hard tube 333 and the discharge port of the suction pipe 1. At this time, the external gas continuously flows into the suction pipe 1 from the feed port of the suction pipe 1, wherein most of the gas moves along the gap between the suction pipe 1 and the dust removal pipe 33 in a spiral trajectory due to the obstruction of the partition plate 34, and finally flows into the exhaust port of the suction pipe 1 to replenish the gas lost in the discharge port of the suction pipe 1, and another small part of the gas passes through the holes of the filter pipe 331 and flows into the filter pipe 331, and then flows into the soft pipe 332 along the filter pipe 331 to replenish the gas lost in the soft pipe 332; After the device is started, the operator holds the suction pipe 1 and adjusts the position of the feeding port of the suction pipe 1 so that the feeding port of the suction pipe 1 is close to the rice. At this time, driven by the airflow, the airflow carries the rice to form a mixed gas and flows into the suction pipe 1 together. In the process of the mixed gas moving in a spiral trajectory, due to the effect of centrifugal force, the rice first slides in the suction pipe 1 along the brush 51. At this time, due to the friction between the rice and the brush 51, the agglomerated rice is initially broken up, and the dust on the outer wall of the rice is swept off. Subsequently, due to the extremely small centrifugal force of powder impurities and dust, the powder impurities and dust are As the gas passes through the holes of the filter tube 331 and flows into the soft tube 332, the hard tube 333 then guides the gas, powder impurities and dust into the filter mechanism 32 and simultaneously intercepts and stores the powder impurities and dust in the filter mechanism 32, while the gas flows into the storage barrel 2 for cutting and absorption, so that after the rice is sucked into the suction tube 1, the rice is directly and gradually separated from the powder impurities and dust, so as to avoid the rice mixed with a large amount of powder impurities and dust sliding in the suction tube 1, resulting in the outer wall of the rice being attached with powder impurities and dust that are difficult to be cleaned by the airflow, thereby affecting the quality of the rice; When the rice is moved away from the position of the brush 51, the rice slides along the inner wall of the storage barrel 2, thereby preventing the rice from contacting the filter tube 331 with a very rough surface during the sliding process, thereby causing damage to the surface of the rice. When the rice slides out of the suction pipe 1, it directly slides into the storage barrel 2. At this time, since the airflow directly flows into a larger space, the airflow velocity drops rapidly, and the thrust of the airflow on the rice also drops rapidly. At this time, due to the effect of the rice's own gravity, the rice entering the storage barrel 2 automatically falls and is stored at the bottom of the storage barrel 2. At the same time, the discharge component 4 continues to discharge the rice in the storage barrel 2 without affecting the suction operation of the device, so as to lift and transport the rice to the corresponding position to complete the rice loading operation.

[0022] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the filtering mechanism 32 includes a filter cartridge 321, a cartridge cover 322 is installed through the top side of the storage cartridge 2, and the top opening of the filter cartridge 321 is threadedly sleeved on the bottom end of the cartridge cover 322, and the cartridge cover 322 and the air pump 31 are in clearance fit, a guide tube 323 is fixedly installed through the center position of the bottom end of the filter cartridge 321, and the discharge end of the hard tube 333 is slidably inserted into the bottom end opening of the guide tube 323; In this embodiment, it should be noted that according to Figure 5 As shown, the wall of the filter cartridge 321 is gap-matched with the wall of the storage cartridge 2; according to Figure 4As shown, the airflow of the mixed powder impurities and dust in the hard tube 333 flows out of the hard tube 333, is introduced into the filter cartridge 321 by the conduit 323, and is retained by the filter cartridge 321 and stored in the filter cartridge 321, while the gas flows into the storage barrel 2 through the holes of the filter cartridge 321 to be sucked by the air pump 31, and according to Figure 5 As shown, since there is a large distance between the top of the conduit 323 and the bottom of the filter cartridge 321 , the powder impurities and dust in the filter cartridge 321 will hardly fall into the conduit 323 when they fall.

[0023] In a further preferred embodiment of the present invention, Figure 3 , Figure 4 and Figure 7 As shown, the bottom opening of the conduit 323 is flared, a soft ring 324 is provided on the top side of the discharge end of the hard tube 333, and the soft ring 324 is fixedly connected to the inner wall of the conduit 323, and honeycomb holes are provided in the soft ring 324; In this embodiment, according to Figure 3 machine Figure 4 As shown, after the hard tube 333 is inserted into the conduit 323, the hard tube 333 and the inner wall of the conduit 323 squeeze the soft ring 324, causing the ring wall of the soft ring 324 to shrink and deform, thereby making the bottom side of the soft ring 324 fit tightly with the top of the hard tube 333, thereby blocking the gap between the hard tube 333 and the inner wall bracket of the conduit 323, so as to prevent gas leakage during the process of airflow flowing into the conduit 323 and bringing powder impurities and dust into the storage barrel 2.

[0024] In a further preferred embodiment of the present invention, Figure 4 and 5 As shown, the discharge assembly 4 includes a turntable 41, which is rotatably mounted on the inner bottom wall of the storage barrel 2 through a bearing, a driver 42 is fixedly mounted on the bottom side of the storage barrel 2, and the driving end of the driver 42 is rotatably inserted into the barrel wall of the storage barrel 2 and fixedly connected to the turntable 41, a storage hole 43 is opened on the turntable 41, a discharge hole 44 is opened at the position of the bottom side of the storage barrel 2 corresponding to the storage hole 43, a baffle 45 is provided on the top side of the turntable 41, and the outer peripheral wall of the baffle 45 is fixedly connected to the inner wall of the storage barrel 2, and a feed hole 46 is opened on the baffle 45 at the position corresponding to the storage hole 43; In this embodiment, it should be noted that according to Figure 5 As shown, the driver 42 is arranged on the bottom side of the storage barrel 2 opposite to the discharge hole 44. The driver 42 is mainly composed of a housing, a plurality of gears and a motor. After the driver 42 is started, the motor starts to drive the turntable 41 to rotate at a constant speed after being driven by a plurality of gears. During the device startup process, according to Figure 4 and Figure 5As shown, the driver 42 drives the turntable 41 located in the storage barrel 2 to rotate at a constant speed. Figure 5 As shown, when the storage hole 43 and the feeding hole 46 coincide with each other, the rice on the baffle 45 quickly passes through the feeding hole 46 and slides into the storage hole 43 until the storage hole 43 is full of rice. Subsequently, after the storage hole 43 and the feeding hole 46 are misaligned, the rice in the feeding hole 46 cannot continue to slide out due to the obstruction of the turntable 41, while the rice in the storage hole 43 makes a circular motion together with the turntable 41. When the storage hole 43 and the discharge hole 44 coincide with each other, the rice in the storage hole 43 quickly slides out of the storage hole 43 and is discharged from the storage barrel 2 through the discharge pipe. Such reciprocating motion can continuously discharge the rice in the storage barrel 2. Moreover, due to the obstruction of the baffle 45 and the turntable 41, while the rice is being discharged, the outside gas hardly flows into the storage barrel 2 through the discharge hole 44, so that the discharge of the rice will not affect the state of the negative pressure chamber in the storage barrel 2, and thus will not affect the suction operation of the device.

[0025] In a further preferred embodiment of the present invention, Figure 5 , Figure 8 and Fig.10 As shown, both ends of the storage hole 43 are flared, and the top side of the turntable 41 is in contact with the bottom side of the baffle 45, and the top side of the baffle 45 is an inclined surface with the outer ring edge concave toward the feed hole 46; In this embodiment, it should be noted that the outer ring edge of the top opening of the storage hole 43 is arranged in an arc shape; according to Figure 5 and Fig.10 As shown, during the misalignment of the material storage hole 43 and the material feeding hole 46, due to the mutual interference between the rice and the outer arc wall of the material storage hole 43, the rice not inserted into the material storage hole 43 can be pushed back into the material feeding hole 46, so as to avoid the misalignment of the material storage hole 43 and the material feeding hole 46 and almost no shrinkage of the rice; according to Figure 5 and Figure 8 As shown, after being ground and falling onto the baffle 45 , the rice slides along the inclined surface of the baffle 45 and gathers at the position of the feed hole 46 to increase the speed at which the rice falls into the storage hole 43 .

[0026] In a further preferred embodiment of the present invention, Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, the scattering mechanism 52 includes a sieve plate 53, which is arranged above the baffle plate 45, and the outer peripheral wall of the sieve plate 53 contacts the inner wall of the storage barrel 2, and a guide hole 54 is opened on the top side of the baffle plate 45, and a push rod 55 is fixedly installed on the bottom side of the sieve plate 53, and the bottom of the push rod 55 is slidably inserted into the guide hole 54, and a roller 56 is rotatably installed on the bottom end of the push rod 55, and the bottom end of the roller 56 contacts the top side of the turntable 41, and a limiting ring 57 is fixedly sleeved on the outer peripheral side of the push rod 55, and the limiting ring 57 is slidably connected to the inner wall of the guide hole 54, and a spring 58 is provided between the top side of the limiting ring 57 and the inner wall of the guide hole 54, and the two ends of the spring 58 are respectively fixedly connected to the limiting ring 57 and the inner wall of the guide hole 54; In this embodiment, according to Figure 4 and Figure 5 As shown, after the rice slides out of the suction pipe 1, it directly falls on the filter plate and collides with the filter plate to a certain extent, thereby performing a secondary breaking operation of the rice. Subsequently, the broken rice passes through the holes of the filter plate and falls on the inclined surface of the baffle plate 45; according to Figure 6 , Figure 8 and Fig. 9 As shown, when the roller 56 moves to the position of the storage hole 43, due to the push of the spring 58 on the limit ring 57, the roller 56 quickly slides out of the guide hole 54, and the filter plate is pulled down quickly by the push rod 55, so that the filter plate and the baffle 45 vibrate strongly, and the vibrating filter plate causes the rice on the filter plate to be displaced, thereby preventing part of the rice from being located between the holes of the filter plate and being unable to pass through the holes of the filter plate. The vibrating baffle 45 accelerates the sliding rate of the rice on the baffle 45, while preventing the situation in which some rice with extremely rough surface cannot slide along the inclined surface of the baffle 45 to the position of the feed hole 46 due to the friction between the baffle 45 and the baffle 45.

[0027] In a further preferred embodiment of the present invention, Figure 6 and Figure 8 As shown, a square rod 59 is fixedly mounted on the bottom side of the sieve plate 53, and the square rod 59 and the push rod 55 are arranged on the bottom side of the sieve plate 53 opposite to each other, a square groove 510 is opened on the top side of the baffle plate 45 at a position corresponding to the square rod 59, and the bottom of the square rod 59 is slidably inserted into the square groove 510; In this embodiment, according to Figure 6 As shown, during the up and down reciprocating movement of the sieve plate 53 , the square rod 59 is driven to slide back and forth in the square groove 510 , thereby constraining the movement trajectory of the sieve plate 53 , so that the sieve plate 53 moves in an up and down linear trajectory.

[0028] In a further preferred embodiment of the present invention, Figure 6 , Fig. 9 and Fig.10As shown, a plurality of hemispherical grooves 511 are provided on the top side of the rotating disk 41, and the spacing between two adjacent hemispherical grooves 511 is equal, and the diameter of the hemispherical groove 511 is smaller than the diameter of the roller 56; In this embodiment, according to Figure 6 and Fig.10 As shown, when the roller 56 moves to the position of the hemispherical groove 511, the roller 56 quickly slides out of the guide hole 54 and pulls the filter plate downward through the push rod 55. Subsequently, due to the mutual interference between the outer arc wall of the roller 56 and the inner arc wall of the hemispherical groove 511, the roller 56 rolls along the inner arc wall of the hemispherical groove 511, is squeezed out of the hemispherical groove 511, and retracts into the guide hole 54. At this time, the push rod 55 pushes the filter plate upward. Figure 5 As shown, as the filter plate reciprocates up and down, the landing point of the rice that slides out of the suction pipe 1 on the filter plate changes accordingly, so that the rice on the filter plate is displaced through the mutual collision between the rice and the condensed rice, thereby preventing part of the rice from being located between the holes of the filter plate and being unable to pass through the holes of the filter plate.

[0029] In a further preferred embodiment of the present invention, Figure 3 As shown, a truncated cone-shaped elastic sleeve 6 is fixedly installed in the feed port of the suction pipe 1, and the end of the filter cartridge 321 away from the soft tube 332 is hemispherical and contacts the inner wall of the discharge port of the elastic sleeve 6, and a plurality of fractures 7 are formed in a circumferential array on the outer peripheral wall of the discharge port of the elastic sleeve 6; In this embodiment, according to Figure 3 As shown, in the process of external gas flowing into the feed port of the suction pipe 1, due to the push of the airflow on the elastic sleeve 6, the elastic sleeve 6 opens from the fracture 7, and with the bending deformation of the sleeve wall at the discharge port of the elastic sleeve 6, a larger gap is formed between the elastic sleeve 6 and the filter tube 331, leaving space for the passage of rice. During the use of the device, when the device is temporarily closed, the negative pressure chamber state in the storage barrel 2 disappears due to the stop of the air pump 31, so that the external gas will not flow into the suction pipe 1. At this time, the elastic sleeve 6 will not be pushed by the airflow, and the elastic sleeve 6 will be deformed and reset to contact the filter tube 331 again, thereby preventing the rice in the suction pipe 1 from sliding out of the feed port of the suction pipe 1.

[0030] Working principle: When the improved rice feeding and lifting device is used, the air pump 31 starts to pump out the gas in the storage barrel 2 at a uniform speed, so that a negative pressure chamber is continuously formed in the storage barrel 2. At this time, due to the obstruction of the turntable 41 and the baffle 45, the external gas will not flow into the storage barrel from the discharge port, so that the gas in the hard tube 333, the soft tube 332 and the discharge port of the suction tube 1 will continue to flow into the storage barrel 2 to replenish the gas lost in the storage barrel 2, thereby making the soft tube 332 and the hard tube 333 A negative pressure state is continuously formed inside the discharge port of the suction pipe 1. At this time, the external gas continuously flows into the suction pipe 1 from the feed port of the suction pipe 1, most of which flows along the gap between the suction pipe 1 and the dust removal pipe 33, and finally flows into the exhaust port of the suction pipe 1 to replenish the gas lost in the discharge port of the suction pipe 1, while another small part of the gas passes through the holes of the filter pipe 331 and flows into the filter pipe 331, and then flows into the soft pipe 332 along the filter pipe 331 to replenish the gas lost in the soft pipe 332; It should be noted that, when the gas flows in the gap between the dust removal pipe 33 and the inner wall of the suction pipe 1, the gas flows in a spiral trajectory due to the blocking and guidance of the partition 34; After the air pump 31 is started, the driver 42 is started synchronously, driving the turntable 41 at the bottom of the storage barrel 2 to rotate slowly and uniformly, and the startup of the device is completed; It should be noted that, in the process of external gas flowing into the feed port of the suction pipe 1, due to the push of the airflow on the elastic sleeve 6, the elastic sleeve 6 is opened from the fracture 7, and with the bending deformation of the sleeve wall at the discharge port of the elastic sleeve 6, a larger gap is formed between the elastic sleeve 6 and the filter tube 331, leaving space for the rice to pass through; After the device is started, the operator holds the suction pipe 1 and adjusts the position of the feeding port of the suction pipe 1 so that the feeding port of the suction pipe 1 is close to the rice. At this time, driven by the airflow, the airflow carries the rice to form a mixed gas and flows into the suction pipe 1 together. In the process of the mixed gas moving in a spiral trajectory, due to the effect of centrifugal force, the rice first slides in the suction pipe 1 along the brush 51. At this time, due to the friction between the rice and the brush 51, the agglomerated rice is initially broken up, and the dust on the outer wall of the rice is swept off. Subsequently, due to the extremely small centrifugal force of powder impurities and dust, the powder impurities and dust follow the gas through the filter tube 331 The air flows into the soft tube 332 through the hole, and then the hard tube 333 guides the gas, powder impurities and dust into the filter cartridge 321 together. Then, due to the interception of the filter cartridge 321, the powder impurities and dust are retained and stored in the filter cartridge 321, while the gas flows out of the filter cartridge 321 through the hole of the filter cartridge 321 and flows into the storage cylinder 2 for suction by the air pump 31, so that after the rice is sucked into the suction pipe 1, the rice is directly and gradually separated from the powder impurities and dust, so as to avoid the rice mixed with a large amount of powder impurities and dust sliding in the suction pipe 1, resulting in the outer wall of the rice being attached with powder impurities and dust that are difficult to be cleaned by the air flow, thereby affecting the quality of the rice; When the rice is removed from the position of the brush 51, the rice slides along the inner wall of the storage barrel 2, thereby preventing the rice from contacting the filter tube 331 with a very rough surface during the sliding process, thereby causing damage to the surface of the rice. When the rice slides out of the suction tube 1, it directly slides into the storage barrel 2. At this time, since the airflow directly flows into a larger space, the airflow velocity decreases rapidly, and the thrust of the airflow on the rice also decreases rapidly. At this time, due to the effect of the rice's own gravity, the rice entering the storage barrel 2 automatically falls, and collides with the filter plate to a certain extent when falling on the filter plate, thereby performing a secondary breaking operation of the rice. Subsequently, the broken rice passes through the holes of the filter plate and falls on the inclined surface of the baffle 45 over the filter plate, and the rice slides along the inclined surface and gathers at the position of the feed hole 46; During the rotation of the turntable 41, due to the push of the spring 58 on the limit ring 57, the roller 56 is synchronously located at the top side of the turntable 41 and rolls. When the roller 56 rolls to the position of the hemispherical groove 511, the roller 56 quickly slides out of the guide hole 54 and pulls the filter plate downward through the push rod 55. Subsequently, due to the mutual interference between the outer arc wall of the roller 56 and the inner arc wall of the hemispherical groove 511, the roller 56 rolls along the inner arc wall of the hemispherical groove 511, is squeezed out of the hemispherical groove 511, and retracts into the guide hole 54. At this time, the push rod 55 pushes the filter plate upward. As the filter plate reciprocates up and down, the landing point of the rice sliding out of the suction pipe 1 on the filter plate changes accordingly, so that the rice on the filter plate is displaced through the mutual collision between the rice and the condensed rice, thereby preventing part of the rice from being located between the holes of the filter plate and being unable to pass through the holes of the filter plate. When the roller 56 moves to the position of the material storage hole 43, due to the push of the spring 58, the filter plate moves down quickly and collides with the baffle plate 45, so that the baffle plate 45 and the filter plate vibrate strongly, and the vibrating filter plate causes the rice on the filter plate to be displaced, thereby preventing part of the rice from being located between the holes of the filter plate and being unable to pass through the holes of the filter plate. The vibrating baffle plate 45 accelerates the sliding speed of the rice on the baffle plate 45, while preventing part of the rice with extremely rough surface from being unable to slide along the inclined surface of the baffle plate 45 to the position of the material feeding hole 46 due to the friction between the baffle plate 45 and the baffle plate 45. As the turntable 41 rotates, after the storage hole 43 and the feed hole 46 overlap, the rice on the baffle 45 quickly passes through the feed hole 46 and slides into the storage hole 43 until the storage hole 43 is full of rice. Then, after the storage hole 43 and the feed hole 46 are misaligned, the rice in the feed hole 46 cannot continue to slide out due to the obstruction of the turntable 41, while the rice in the storage hole 43 moves in a circle with the turntable 41. After the storage hole 43 and the discharge hole 44 overlap, the rice in the storage hole 43 quickly slides out of the storage hole 43 and is discharged from the storage barrel 2 through the discharge pipe. When using the device, the storage barrel 2 is fixed in the feed port of the rice processing equipment, and the lifting and loading operation of the rice processing equipment can be continuously completed. During the use of the device, when the device is temporarily closed, the air pump 31 stops moving, and the negative pressure chamber state in the storage barrel 2 disappears, so that the external gas will no longer flow into the suction pipe 1. At this time, the elastic sleeve 6 will not be pushed by the airflow, and the elastic sleeve 6 will be deformed and reset to contact the filter tube 331 again, thereby preventing the rice in the suction pipe 1 from sliding out from the feeding port of the suction pipe 1; After the device is used, the operator holds the handle of the cylinder cover 322 and rotates the cylinder cover 322 in the opposite direction. After the cylinder cover 322 is screwed out of the storage cylinder 2, the operator can directly pull the filter cartridge 321 out of the storage cylinder 2 by pulling the handle, and at the same time, the discharge end of the hard tube 333 is pulled out from the bottom opening of the guide tube 323. After the filter cartridge 321 is taken out of the storage cylinder 2, the operator holds the filter cartridge 321 with one hand and rotates the cylinder cover 322 in the opposite direction with the other hand, so as to screw the cylinder cover 322 out of the filter cartridge 321. Then the operator inverts the filter cartridge 321, and powder, sundries, impurities, dust and the like can be poured out from the filter cartridge 321, thereby completing the cleaning of powder, impurities and dust in the device. After the powder impurities and dust in the cylinder 321 are cleaned, the operator screws the cylinder cover 322 into the top opening of the filter cylinder 321 again, then reinserts the filter cylinder 321 into the storage cylinder 2, and screws the cylinder cover 322 back into the cylinder wall of the storage cylinder 2. At the same time, the discharge end of the hard tube 333 is reinserted into the bottom opening of the conduit 323. This is because the discharge end of the hard tube 333 and the inner wall of the conduit 323 squeeze the soft ring 324, and the ring wall of the soft ring 324 shrinks and deforms, so that the soft ring 324 and the discharge end of the hard tube 333 are tightly attached to close the gap between the hard tube 333 and the inner wall of the conduit 323, and the connection operation between the hard tube 333 and the conduit 323 is automatically completed.

[0031] Embodiment 2: A rice feeding method, comprising the above-mentioned rice feeding and lifting device, specifically comprises the following steps: Step 1: First, the operator starts the air pump 31 and the driver 42, and the external gas flows in from the feeding end of the suction pipe 1 and is extracted by the air pump 31 after flowing into the storage barrel 2. At the same time, the started driver 42 drives the turntable 41 to rotate at a constant speed, so that the storage hole 43 repeatedly overlaps with the feeding hole 46 and the discharge hole 44 in sequence; Step 2: After the device is started, the operator holds the suction pipe 1 to adjust the position of the suction end of the suction pipe 1, and brings the suction end of the suction pipe 1 close to the rice. The airflow carries the rice into the storage barrel 2 and falls on the baffle 45. Then the rice slides along the inclined surface of the baffle 45 and gathers at the position of the feed hole 46. Step 3: In the process of sucking rice by the suction pipe 1 in step 2, the rice is separated from the powder impurities and dust by the airflow, and the powder impurities and dust are brought into the filter cartridge 321 by the airflow for storage; Step 4: According to step 1, after the storage hole 43 and the feed hole 46 overlap, the rice quickly passes through the feed hole 46 and falls into the storage hole 43 until the rice fills the storage hole 43. Then, after the storage hole 43 and the discharge hole 44 overlap, the rice quickly slides out of the storage barrel 2 from the discharge hole 44. In this embodiment, the improved rice feeding and lifting device has a simple structure and low manufacturing cost, and the use of the device is almost the same as that of the existing equipment, which facilitates the use of the device.
