Description

Technical Field

[0001] This invention relates to the technical field of rice feeding devices, and more particularly to a rice feeding and lifting device and feeding method. Background Technology

[0002] Rice, also known as paddy rice, is a food made from paddy rice through processes such as cleaning, hulling, milling, and finishing. During the rice processing process, because the feed inlet of rice processing equipment is often located at a high position, the rice is generally transported to the feed inlet of the rice processing equipment by a feeding and lifting device for feeding.

[0003] In some rice feeding and lifting devices, rice is typically drawn into a suction pipe by airflow during the rice feeding process. The suction pipe then guides the rice into the feed inlet of the rice processing equipment. During this process, the airflow also draws in a large amount of powder, impurities, and dust. As the rice slides within the suction pipe, it mixes with these powder, impurities, and dust, potentially leaving a small amount of these residues that are difficult for the airflow to remove on the outer surface of the rice, thus affecting the quality of the rice. Summary of the Invention

[0004] The purpose of this invention is to provide a rice feeding and lifting device and a feeding method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rice feeding and lifting device, comprising a suction pipe and a storage cylinder, wherein the discharge end of the suction pipe is located on the outer periphery of the storage cylinder and is connected to the storage cylinder;

[0011] Preferably, the bottom opening of the conduit is flared, and a soft ring is provided on the top side of the discharge end of the rigid tube, and the soft ring is fixedly connected to the inner wall of the conduit, and honeycomb-shaped holes are formed inside the soft ring.

[0012] Preferably, the discharge assembly includes a turntable, which is rotatably mounted on the inner bottom wall of the storage cylinder via bearings. A driver is fixedly mounted on the bottom side of the storage cylinder, and the driving end of the driver is rotatably inserted into the cylinder wall of the storage cylinder and fixedly connected to the turntable. A storage hole is opened on the turntable, and a discharge hole is opened on the bottom side of the storage cylinder at the position corresponding to the storage hole. A baffle is provided on the top side of the turntable, and the outer peripheral wall of the baffle is fixedly connected to the inner wall of the storage cylinder. A feed hole is opened on the baffle at the position corresponding to the storage hole.

[0013] Preferably, the openings at both ends of the storage hole are flared, and the top side of the turntable is in contact with the bottom side of the baffle. The top side of the baffle is a sloping surface with the outer ring edge recessed towards the feed hole.

[0014] Preferably, the dispersing mechanism includes a sieve plate, which is disposed above the baffle and its outer peripheral wall is in contact with the inner wall of the storage cylinder. A guide hole is provided on the top side of the baffle. A push rod is fixedly installed on the bottom side of the sieve plate, and the bottom of the push rod is slidably inserted into the guide hole. A roller is rotatably installed at the bottom end of the push rod, and the bottom end of the roller is in contact with the top side of the turntable. A limiting ring is fixedly sleeved on the outer peripheral side of the push rod, and the limiting ring is slidably connected to the inner wall of the guide hole. A spring is provided between the top side of the limiting ring and the inner wall of the guide hole, and the two ends of the spring are fixedly connected to the limiting ring and the inner wall of the guide hole, respectively.

[0015] Preferably, a square rod is fixedly installed on the bottom side of the sieve plate, and the square rod and the push rod are arranged opposite each other on the bottom side of the sieve plate. A square groove is opened on the top side of the baffle corresponding to the position of the square rod, and the bottom of the square rod is slidably inserted into the square groove.

[0016] Preferably, the top side of the turntable has a plurality of hemispherical grooves, and the distance between two adjacent hemispherical grooves is equal, and the diameter of the hemispherical grooves is smaller than the diameter of the roller.

[0017] Preferably, an elastic sleeve in the shape of a frustum is fixedly installed inside the feed inlet of the suction pipe, and the end of the filter cylinder away from the soft tube is hemispherical and in contact with the inner wall of the discharge port of the elastic sleeve. Several breaks are opened in a circular array on the outer peripheral wall of the discharge port of the elastic sleeve.

[0018] A method for feeding rice, including the aforementioned rice feeding and lifting device, specifically includes the following steps:

[0019] Step 1: First, the operator starts the air pump and driver. External air flows in from the feed end of the suction pipe and is then drawn out by the air pump after flowing into the storage cylinder. At the same time, the driver starts and drives the turntable to rotate at a constant speed, so that the storage hole repeatedly overlaps with the feed hole and the discharge hole in sequence.

[0020] Step 2: After the device is started, the operator holds the suction tube and adjusts the position of the suction end of the suction tube. The suction end of the suction tube is brought close to the rice. The airflow carries the rice into the storage cylinder and falls onto the baffle. Then the rice slides along the slope of the baffle and gathers at the feed hole.

[0021] Step 3: During the process of sucking up rice in Step 2, the rice is simultaneously separated from powder impurities and dust by airflow, and the airflow carries the powder impurities and dust into the filter cartridge for storage.

[0022] Step four: As shown in step one, after the storage hole and the feed hole coincide, the rice quickly passes through the feed hole and falls into the storage hole until the storage hole is filled with rice. Then, after the storage hole and the discharge hole coincide, the rice quickly slides out of the storage cylinder from the discharge hole.

[0023] This invention has at least the following beneficial effects:

[0024] 1. When using this improved rice feeding and lifting device, the rice is lifted and transported to the corresponding position by suction to complete the rice feeding operation. After the rice is sucked into the suction pipe, the airflow directly and gradually separates the rice from the powder impurities and dust, so as to avoid the rice mixed with a large amount of powder impurities and dust sliding together in the suction pipe, resulting in powder impurities and dust that are difficult to be cleaned by airflow adhering to the outer wall of the rice, which affects the quality of the rice.

[0025] 2. During the process of the rice sliding inside the suction tube, due to the obstruction and guidance of the baffle, the airflow and the rice slide in a spiral trajectory inside the suction tube. Due to the centrifugal force, the rice slides against the brush and the inner wall of the suction tube, thus avoiding contact between the rice and the filter tube with a very rough surface during the sliding process, which would cause damage to the surface of the rice. In addition, during the process of the rice sliding against the brush, due to the friction between the rice and the brush, the clumps of rice are initially broken up, and the dust on the outer wall of the rice is swept off, thereby enhancing the separation effect of rice from powder impurities and dust.

[0038] To make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0039] Example 1: The present invention provides a technical solution: Refer to Figure 1 - Figure 6 The present invention discloses a rice feeding and lifting device, including a suction pipe 1 and a storage cylinder 2. The discharge end of the suction pipe 1 is located on the outer periphery of the storage cylinder 2 and is connected to the storage cylinder 2.

[0040] Also includes:

[0041] The suction assembly 3 includes an air pump 31 fixedly installed on the top side of the storage cylinder 2, and the air inlet end of the air pump 31 is fixedly inserted through the cylinder wall of the storage cylinder 2. The storage cylinder 2 is provided with a filter mechanism 32. A dust removal pipe 33 is provided at the axial position inside the suction pipe 1. A partition 34 is fixedly wound around the outer periphery of the dust removal pipe 33 in a spiral shape, and the partition 34 is fixedly connected to the inner wall of the suction pipe 1. The dust removal pipe 33 is mainly composed of three parts: a filter pipe 331, a soft pipe 332, and a hard pipe 333. The two ends of the soft pipe 332 are respectively connected to the discharge end of the filter pipe 331 and the feed end of the hard pipe 333. The discharge end of the hard pipe 333 is L-shaped and inserted into the storage cylinder 2. The feed end of the hard pipe 333 is fixedly connected to the inner wall of the suction pipe 1 through several connecting rods.

[0042] Discharge assembly 4 is located at the bottom of storage cylinder 2 and continuously discharges rice from storage cylinder 2.

[0043] The dispersing component 5 includes several brushes 51, which are fixedly installed on the inner wall of the feed end of the suction pipe 1. The brushes 51 are located between the partition 34 and the dust removal pipe 33 and the inner wall of the suction pipe 1. The storage cylinder 2 is provided with a dispersing mechanism 52.

[0044] In this embodiment, it should be noted that the suction pipe 1, filter pipe 331, and partition 34 described above are all made of soft materials, such as soft plastic or rubber. Figure 5 As shown, the connecting rod is located inside the cylinder wall of the storage cylinder 2;

[0045] When the improved rice feeding and lifting device is in use, the air pump 31 starts and draws out the gas in the storage cylinder 2 at a constant speed, so that a negative pressure chamber is continuously formed in the storage cylinder 2. The gas in the rigid tube 333, the flexible tube 332 and the discharge port of the suction pipe 1 continuously flows into the storage cylinder 2 to replenish the gas lost in the storage cylinder 2. This makes the flexible tube 332, the rigid tube 333 and the discharge port of the suction pipe 1 continuously form a negative pressure state. At this time, the external gas continuously flows into the suction pipe 1 through the inlet. Due to the obstruction of the partition 34, most of the gas moves along the gap between the suction pipe 1 and the dust removal tube 33 in a spiral trajectory 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. A small part of the gas passes through the holes of the filter tube 331 and flows into the filter tube 331. Then it flows along the filter tube 331 into the flexible tube 332 to replenish the gas lost in the flexible tube 332.

[0046] After the device is started, the operator holds the suction pipe 1 and adjusts the position of the inlet of the suction pipe 1 so that the inlet is close to the rice. At this time, due to the airflow, the airflow carries the rice to form a mixed gas that flows into the suction pipe 1. As the mixed gas moves in a spiral trajectory, due to the centrifugal force, the rice first slides along the brush 51 inside the suction pipe 1. At this time, due to the friction between the rice and the brush 51, the clumps of rice are initially broken up, and the dust on the outer wall of the rice is swept off. Subsequently, because the centrifugal force on powder impurities and dust is extremely small, the powder impurities and dust are swept away. As the gas passes through the holes in the filter tube 331, it flows into the soft tube 332. Then, the rigid tube 333 guides the gas, powder impurities, and dust into the filter mechanism 32, where the powder impurities and dust are simultaneously trapped and stored. Meanwhile, the gas flows into the storage cylinder 2 for suction. Thus, after the rice is sucked into the suction tube 1, the separation of rice from powder impurities and dust is completed step by step. This prevents the rice from sliding in the suction tube 1 with a large amount of powder impurities and dust mixed together, which would cause powder impurities and dust that are difficult to clean by airflow to adhere to the outer wall of the rice, affecting the quality of the rice.

[0047] As the rice is removed from the brush 51, it slides along the inner wall of the storage cylinder 2, thus preventing it from contacting the filter tube 331 with its extremely rough surface during the sliding process, which would damage the rice's surface. When the rice slides out of the suction tube 1, it slides directly into the storage cylinder 2. At this time, because the airflow flows directly into a large space, the airflow velocity drops rapidly, and the airflow's thrust on the rice also drops rapidly. Due to the rice's own gravity, the rice that has entered the storage cylinder 2 automatically falls and is stored at the bottom of the storage cylinder 2. At the same time, the discharge component 4 continuously discharges the rice from the storage cylinder 2 without affecting the device's suction operation, so as to lift and transport the rice to the corresponding position, completing the rice feeding operation.

[0048] In a further preferred embodiment of the invention, such as Figure 4 and Figure 5 As shown, the filtration mechanism 32 includes a filter cylinder 321. A cylinder cover 322 is threaded through the top side of the storage cylinder 2, and the top opening of the filter cylinder 321 is threadedly fitted onto the bottom end of the cylinder cover 322. The cylinder cover 322 is clearance-fitted with the air pump 31. A conduit 323 is fixedly installed through the center of the bottom end of the filter cylinder 321, and the discharge end of the rigid tube 333 is slidably inserted into the bottom opening of the conduit 323.

[0049] In this embodiment, it should be noted that, according to Figure 5 As shown, the wall of the filter cartridge 321 is fitted with the wall of the storage cylinder 2 with a clearance.

[0050] according to Figure 4 As shown, the airflow containing powder impurities and dust mixed in the rigid tube 333 flows out of the rigid tube 333 and is then introduced into the filter cartridge 321 through the conduit 323. The air is then trapped and stored in the filter cartridge 321, while the gas flows through the holes in the filter cartridge 321 into the storage cylinder 2 for the air pump 31 to draw in. According to... Figure 5 As shown, due to the large gap between the top of the guide tube 323 and the bottom of the inner cylinder of the filter cartridge 321, the powder impurities and dust in the filter cartridge 321 will hardly fall into the guide tube 323 when they fall.

[0051] In a further preferred embodiment of the invention, such as Figure 3 , Figure 4 and Figure 7 As shown, the bottom opening of the guide tube 323 is flared, and a soft ring 324 is provided on the top side of the discharge end of the rigid tube 333. The soft ring 324 is fixedly connected to the inner wall of the guide tube 323, and honeycomb-shaped holes are opened in the soft ring 324.

[0052] In this embodiment, according to Figure 3 machine Figure 4As shown, after the rigid tube 333 is inserted into the conduit 323, the soft ring 324 is compressed by the rigid tube 333 and the inner wall of the conduit 323. The ring wall of the soft ring 324 shrinks and deforms, which makes the bottom side of the soft ring 324 fit tightly against the top of the rigid tube 333, thereby sealing the gap between the rigid tube 333 and the inner wall support of the conduit 323. This prevents gas leakage during the flow of air into the conduit 323, which would carry powder impurities and dust into the storage cylinder 2.

[0053] In a further preferred embodiment of the invention, such as 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 cylinder 2 via a bearing. A driver 42 is fixedly mounted on the bottom side of the storage cylinder 2, and the driving end of the driver 42 is rotatably inserted into the cylinder wall of the storage cylinder 2 and fixedly connected to the turntable 41. A storage hole 43 is provided on the turntable 41, and a discharge hole 44 is provided on the bottom side of the storage cylinder 2 at the position 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 cylinder 2. A feed hole 46 is provided on the baffle 45 at the position corresponding to the storage hole 43.

[0054] In this embodiment, it should be noted that, according to Figure 5 As shown, the driver 42 is located opposite to the discharge hole 44 on the bottom side of the storage cylinder 2. The driver 42 is mainly composed of a housing, several gears and a motor. After the driver 42 is started, the motor starts and drives the turntable 41 to rotate at a constant speed after being transmitted through several gears.

[0055] During the device startup process, according to Figure 4 and Figure 5 As shown, the driver 42 drives the turntable 41 to rotate at a constant speed inside the storage cylinder 2, according to... Figure 5 As shown, when the storage hole 43 coincides with the feed hole 46, the rice on the baffle 45 quickly slides through the feed hole 46 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 circular motion with the turntable 41. When the storage hole 43 coincides with the discharge hole 44, the rice in the storage hole 43 quickly slides out from the storage hole 43 and is discharged from the discharge pipe into the storage cylinder 2. This repetition allows the rice in the storage cylinder 2 to be continuously discharged. Due to the obstruction of the baffle 45 and the turntable 41, while the rice is being discharged, almost no external gas flows into the storage cylinder 2 from the discharge hole 44, so that the discharge of rice will not affect the negative pressure state in the storage cylinder 2, and thus will not affect the suction operation of the device.

[0056] In a further preferred embodiment of the invention, such as Figure 5 , Figure 8 and Figure 10 As shown, the openings at 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. The top side of the baffle 45 is a sloping surface with the outer ring edge recessed towards the feed hole 46.

[0057] In this embodiment, it should be noted that the outer ring edge of the top opening of the storage hole 43 is arc-shaped;

[0058] according to Figure 5 and Figure 10 As shown, during the misalignment of the storage hole 43 and the feed hole 46, due to the mutual contact between the rice and the outer arc wall of the storage hole 43, the rice that has not been inserted into the storage hole 43 can be pushed back into the feed hole 46, so as to avoid the rice shrinking almost during the misalignment of the storage hole 43 and the feed hole 46.

[0059] according to Figure 5 and Figure 8 As shown, after the rice falls onto the baffle 45, it slides along the inclined surface of the baffle 45 and gathers at the feed hole 46 to increase the speed at which the rice falls into the storage hole 43.

[0060] In a further preferred embodiment of the invention, such as Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the dispersing mechanism 52 includes a sieve plate 53, which is located above the baffle 45. The outer peripheral wall of the sieve plate 53 is in contact with the inner wall of the storage cylinder 2. A guide hole 54 is provided on the top side of the baffle 45. A push rod 55 is fixedly installed on the bottom side of the sieve plate 53. The bottom of the push rod 55 is slidably inserted into the guide hole 54. A roller 56 is rotatably installed on the bottom end of the push rod 55. The bottom end of the roller 56 is in contact with the top side of the turntable 41. A limiting ring 57 is fixedly sleeved on the outer peripheral side of the push rod 55. The limiting ring 57 is slidably connected to the inner wall of the guide hole 54. A spring 58 is provided between the top side of the limiting ring 57 and the inner wall of the guide hole 54. The two ends of the spring 58 are fixedly connected to the limiting ring 57 and the inner wall of the guide hole 54, respectively.

[0061] In this embodiment, according to Figure 4 and Figure 5 As shown, after the rice slides out of the suction pipe 1, it falls directly onto the filter plate and collides with the filter plate to a certain extent, thus performing a secondary dispersing operation on the rice. After being dispersed, the rice passes through the holes of the filter plate and falls onto the inclined surface of the baffle 45.

[0062] according to Figure 6 , Figure 8 and Figure 9As shown, when the roller 56 moves to the position of the storage hole 43, due to the push of the spring 58 on the limiting ring 57, the roller 56 quickly slides out of the guide hole 54 and pulls the filter plate down quickly through the push rod 55, so that the filter plate and the baffle 45 vibrate strongly. The vibrating filter plate causes the rice on the filter plate to move, avoiding some rice from being located between the holes of the filter plate and unable to pass through the holes of the filter plate. The vibrating baffle 45 accelerates the sliding speed of the rice on the baffle 45, while preventing some rice with extremely rough surfaces from being unable to slide along the inclined surface of the baffle 45 to the position of the feed hole 46 due to the friction between itself and the baffle 45.

[0063] In a further preferred embodiment of the invention, such as Figure 6 and Figure 8 As shown, a square rod 59 is fixedly installed on the bottom side of the sieve plate 53, and the square rod 59 and the push rod 55 are arranged opposite to each other on the bottom side of the sieve plate 53. A square groove 510 is opened on the top side of the baffle 45 at the position corresponding to the square rod 59, and the bottom of the square rod 59 is slidably inserted into the square groove 510.

[0064] In this embodiment, according to Figure 6 As shown, during the reciprocating up and down movement of the sieve plate 53, the square rod 59 is driven to slide back and forth within the square groove 510, thereby constraining the movement trajectory of the sieve plate 53 and causing the sieve plate 53 to move along an up-and-down linear trajectory.

[0065] In a further preferred embodiment of the invention, such as Figure 6 , Figure 9 and Figure 10 As shown, a number of hemispherical grooves 511 are provided on the top side of the turntable 41, and the distance between two adjacent hemispherical grooves 511 is equal. The diameter of the hemispherical grooves 511 is smaller than the diameter of the roller 56.

[0066] In this embodiment, according to Figure 6 and Figure 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 down through the push rod 55. Subsequently, due to the mutual abutment 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 back into the guide hole 54. At this time, the push rod 55 pushes the filter plate up. Figure 5 As shown, as the filter plate moves up and down, the landing point of the rice sliding out of the suction pipe 1 on the filter plate changes accordingly. Thus, through the mutual collision between the rice and the condensed rice, the rice on the filter plate is displaced, preventing some rice from being located between the holes of the filter plate and unable to pass through the holes.

[0067] In a further preferred embodiment of the invention, such as Figure 3As shown, an elastic sleeve 6 in the shape of a frustum is fixedly installed inside the feed inlet of the suction pipe 1, and the end of the filter cylinder 321 away from the soft tube 332 is hemispherical and in contact with the inner wall of the discharge port of the elastic sleeve 6. Several breaks 7 are opened in a circular array on the outer peripheral wall of the discharge port of the elastic sleeve 6.

[0068] In this embodiment, according to Figure 3 As shown, during the process of external gas flowing into the inlet of the suction pipe 1, the elastic sleeve 6 is pushed by the airflow and opens from the break 7. As the sleeve wall at the discharge port of the elastic sleeve 6 bends and deforms, a large gap is formed between the elastic sleeve 6 and the filter pipe 331, leaving space for the rice to pass through. When the device is temporarily shut down during use, the negative pressure chamber in the storage cylinder 2 also disappears as the air pump 31 stops moving, thus preventing external gas from flowing into the suction pipe 1. At this time, the elastic sleeve 6 is no longer pushed by the airflow, and the elastic sleeve 6 deforms and resets to contact the filter pipe 331 again, thereby preventing the rice in the suction pipe 1 from sliding out from the inlet of the suction pipe 1.

[0069] Working principle: When this improved rice feeding and lifting device is in use, the air pump 31 starts and draws the gas out of the storage cylinder 2 at a constant speed, so that a negative pressure chamber is continuously formed inside the storage cylinder 2. At this time, due to the obstruction of the turntable 41 and the baffle 45, the outside gas will not flow into the storage cylinder from the discharge port. This allows the gas in the rigid tube 333, the flexible tube 332 and the discharge port of the suction pipe 1 to continuously flow into the storage cylinder 2 to replenish the gas lost in the storage cylinder 2. In turn, the gas in the flexible tube 332 and the rigid tube 333... A negative pressure state is continuously formed inside the discharge port of the suction pipe 1. At this time, the outside gas continuously flows into the suction pipe 1 through the feed port. Most of the gas 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. Another small part of the gas passes through the holes of the filter pipe 331 and flows into the filter pipe 331. Then it flows along the filter pipe 331 into the soft pipe 332 to replenish the gas lost in the soft pipe 332.

[0070] It should be noted that during the process of the gas flowing 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 obstruction and guidance of the baffle 34.

[0071] After the air pump 31 is started, the driver 42 starts synchronously, and the drive turntable 41 rotates slowly and uniformly at the bottom of the storage cylinder 2, and the start-up of the device is completed.

[0072] It should be noted that during the process of external gas flowing into the feed inlet of the suction pipe 1, the elastic sleeve 6 is pushed by the airflow and opens from the break 7. As the sleeve wall at the discharge port of the elastic sleeve 6 bends and deforms, a large gap is formed between the elastic sleeve 6 and the filter pipe 331, leaving space for the rice to pass through.

[0073] After the device is started, the operator holds the suction pipe 1 and adjusts the position of the inlet of the suction pipe 1 so that the inlet is close to the rice. At this time, due to the airflow, the airflow carries the rice to form a mixed gas that flows into the suction pipe 1. As the mixed gas moves in a spiral trajectory, due to the centrifugal force, the rice first slides along the brush 51 inside the suction pipe 1. At this time, due to the friction between the rice and the brush 51, the clumps of rice are initially broken up, and the dust on the outer wall of the rice is swept off. Subsequently, because the centrifugal force on powder impurities and dust is extremely small, the powder impurities and dust pass through the filter pipe 331 along with the gas. The gas flows into the flexible tube 332 through the holes, and then the rigid tube 333 guides the gas, powder impurities, and dust into the filter cartridge 321. Due to the interception of the filter cartridge 321, the powder impurities and dust are trapped and stored in the filter cartridge 321, while the gas flows out of the filter cartridge 321 through the holes and flows into the storage cylinder 2 for the air pump 31 to draw in. This allows the rice to be separated from the powder impurities and dust directly and gradually after it is drawn into the suction pipe 1, so as to avoid the rice from sliding in the suction pipe 1 with a large amount of powder impurities and dust mixed together, which would cause the outer wall of the rice to be covered with powder impurities and dust that are difficult to be cleaned by the airflow, thus affecting the quality of the rice.

[0074] When the rice is removed from the brush 51, it slides along the inner wall of the storage cylinder 2, thus avoiding contact with the filter tube 331 with its extremely rough surface during the sliding process, which would damage the surface of the rice. When the rice slides out of the suction tube 1, it slides directly into the storage cylinder 2. At this time, because the airflow flows directly into a large 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 that has entered the storage cylinder 2 falls automatically and collides with the filter plate to a certain extent when it falls onto the filter plate, thus performing a secondary dispersing operation of the rice. After that, the dispersed rice passes through the holes of the filter plate and falls onto the inclined surface of the baffle 45. The rice slides along the inclined surface and gathers at the feed hole 46.

[0075] During the rotation of turntable 41, due to the push of spring 58 on limit ring 57, roller 56 rolls synchronously on top side of turntable 41. When roller 56 rolls to the position of hemispherical groove 511, roller 56 quickly slides out of guide hole 54 and pulls filter plate down through push rod 55. Then, due to the mutual abutment between outer arc wall of roller 56 and inner arc wall of hemispherical groove 511, roller 56 rolls along inner arc wall of hemispherical groove 511, is squeezed out of hemispherical groove 511, and retracts into guide hole 54. At this time, push rod 55 pushes filter plate up. As filter plate moves up and down, the landing point of rice sliding out of suction pipe 1 on filter plate changes accordingly. Thus, through the mutual collision between rice and condensed rice, the rice on filter plate is displaced, avoiding some rice from being located between the holes of filter plate and unable to pass through the holes of filter plate.

[0076] When the roller 56 moves to the storage hole 43, the filter plate moves down rapidly due to the push of the spring 58 and collides with the baffle 45, which causes the baffle 45 and the filter plate to vibrate strongly. The vibrating filter plate causes the rice on the filter plate to move, preventing some rice from being trapped between the holes of the filter plate and unable to pass through the holes. The vibrating baffle 45 accelerates the sliding speed of the rice on the baffle 45, while preventing some rice with extremely rough surfaces from being unable to slide along the slope of the baffle 45 to the feed hole 46 due to the friction between itself and the baffle 45.

[0077] As the turntable 41 rotates, after the storage hole 43 and the feed hole 46 coincide, the rice on the baffle 45 quickly slides through the feed hole 46 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 circular motion with the turntable 41. After the storage hole 43 and the discharge hole 44 coincide, the rice in the storage hole 43 quickly slides out from the storage hole 43 and is discharged from the discharge pipe into the storage cylinder 2. When using this device, the storage cylinder 2 is fixed in the feed inlet of the rice processing equipment, and the lifting and feeding operation of the rice processing equipment can be continuously completed.

[0078] When the device is temporarily shut down during use, the negative pressure chamber in the storage cylinder 2 will disappear as the air pump 31 stops moving, thus preventing external gas from flowing into the suction pipe 1. At this time, the elastic sleeve 6 will no longer be pushed by the airflow, and the elastic sleeve 6 will deform and reset to contact the filter pipe 331 again, thereby preventing the rice in the suction pipe 1 from sliding out from the inlet of the suction pipe 1.

[0079] After the device is used, the operator holds the handle of the cylinder cover 322 and rotates it in the opposite direction. After unscrewing the cylinder cover 322 from the storage cylinder 2, the operator can pull the filter cylinder 321 directly out of the storage cylinder 2 by pulling the handle, and at the same time, the discharge end of the rigid tube 333 is pulled out from the bottom opening of the guide tube 323. After removing the filter cylinder 321 from the storage cylinder 2, the operator holds the filter cylinder 321 with one hand and rotates the cylinder cover 322 in the opposite direction with the other hand to unscrew the cylinder cover 322 from the filter cylinder 321. Then, the operator inverts the filter cylinder 321 to pour out powder, impurities, dust, etc., thus completing the cleaning of powder, impurities, and dust inside the device. After the powder impurities and dust inside the cylinder 321 are cleaned, the operator screws the cylinder cover 322 back into the top opening of the filter cylinder 321, 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 rigid tube 333 is reinserted into the bottom opening of the guide tube 323. This is because the discharge end of the rigid tube 333 and the inner wall of the guide tube 323 squeeze the soft ring 324, causing the ring wall of the soft ring 324 to shrink and deform. This makes the soft ring 324 and the discharge end of the rigid tube 333 tightly adhere to and seal the gap between the rigid tube 333 and the inner wall of the guide tube 323, automatically completing the connection operation between the rigid tube 333 and the guide tube 323.

[0080] Example 2: A rice feeding method, including the above-mentioned rice feeding and lifting device, specifically includes the following steps:

[0081] Step 1: First, the operator starts the air pump 31 and the driver 42. The outside air flows in from the feed end of the suction pipe 1 and is then drawn out by the air pump 31 after flowing into the storage cylinder 2. At the same time, the driver 42 drives the turntable 41 to rotate at a constant speed, so that the storage hole 43 repeatedly overlaps with the feed hole 46 and the discharge hole 44 in sequence.

[0082] Step 2: After the device is started, the operator holds the suction pipe 1 and adjusts the position of the suction end of the suction pipe 1. The suction end of the suction pipe 1 is brought close to the rice. The airflow carries the rice into the storage cylinder 2 and falls on the baffle 45. Then the rice slides along the slope of the baffle 45 and gathers at the feed hole 46.

[0083] Step 3: During the process of sucking rice in 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 carried into the filter cartridge 321 for storage by the airflow.

[0084] Step 4: As shown in Step 1, after the storage hole 43 and the feed hole 46 coincide, the rice quickly passes through the feed hole 46 and falls into the storage hole 43 until the storage hole 43 is filled with rice. Then, after the storage hole 43 and the discharge hole 44 coincide, the rice quickly slides out of the storage cylinder 2 from the discharge hole 44.

[0085] In this embodiment, the improved rice feeding and lifting device has a simple structure, low manufacturing cost, and its usage is almost identical to that of existing equipment, making it convenient to use.
