Description

Technical Field

[0001] The present invention relates to the technical field of material conveying equipment, in particular to a spiral feeding device for rice processing and a use method thereof. Background Art

[0002] Screw feeding equipment is a mechanical device used for material transportation. It is widely used in grain, feed, fertilizer, ore, coal and other industries. It is particularly suitable for conveying granular, powdered and granular mixed materials. It can convey horizontally, inclined or vertically. It has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient closed transportation.

[0003] During the storage and transportation of rice, some rice may become damp. The surface of damp rice has stronger adhesion. When transporting damp rice, the rice grains may attract each other, causing the rice to agglomerate into lumps, which can easily cause blockage or stagnation during transportation, affecting the stable transportation of rice. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a spiral feeding device for rice processing, comprising a conveying pipe, a motor fixedly connected to the side wall of the conveying pipe, a spiral auger rotatably connected to the inner wall of the conveying pipe, the side wall of the spiral auger is fixedly connected to the output end of the side wall of the motor, a feed pipe fixedly connected to the outer wall of the conveying pipe, and a discharge pipe fixedly connected to the outer wall of the conveying pipe;

[0005] The stirring mechanism includes a rotating rod, a stirring block for stirring the rice inside the conveying pipe, a spring sliding rod, and a concave-convex ring, a separation component for separating the rice inside the conveying pipe;

[0006] The side wall of the rotating rod is fixedly connected to the side wall of the spiral auger, and there are five stirring blocks, and the outer walls of the five stirring blocks are all slidably connected to the inner wall of the rotating rod, and the outer wall of the spring sliding rod is slidably connected to the inner wall of the rotating rod, and the side wall of the concave and convex ring is fixedly connected to the side wall of the conveying pipe, and the side walls of the five stirring blocks are fixedly connected to the side wall of the spring sliding rod, so that the rice enters the conveying pipe through the feeding pipe, and then the motor is started to drive the spiral auger to rotate to convey the rice. When the spiral auger rotates, it will also drive the rotating rod to rotate, thereby causing the stirring block to rotate and drive the spring sliding rod to rotate. When the spring sliding rod contacts the convex position of the concave and convex ring during the rotation process, the spring sliding rod will be squeezed, causing the spring sliding rod to move away from the conveying pipe, causing the spring on the spring sliding rod to be stretched, accumulating rebound force, and when the spring sliding rod moves, it will also drive the stirring block to move toward the left inner wall of the conveying pipe. By breaking up the rice that has agglomerated and spraying gas at the same time, the rice is further dispersed, which effectively prevents the rice from being stuck or blocked, ensures that the conveying pipeline is unobstructed, and can stably convey the rice.

[0007] Preferably, the separation assembly includes a spring plate slidably connected to the inner wall of the stirring block, the inner walls of the five stirring blocks are slidably connected to push rods, the side walls of the five push rods are rotatably connected to connecting rods, the inner walls of the five connecting rods are rotatably connected to the bottoms of the five spring plates, and the side walls of the five push rods are in contact with the inner wall of the conveying pipe.

[0008] Preferably, the separation component also includes several blocking rods fixedly connected to the top of the spring plate, several air jet holes are opened on the inner walls of the five stirring blocks, the outer walls of the several blocking rods are slidably connected to the inner walls of the several air jet holes, and a protective component is provided on the inner wall of the conveying pipe.

[0009] Preferably, the protective component includes a fixed cylinder fixedly connected to the inner wall of the conveying pipe, a spring sliding ring is slidably connected to the inner wall of the fixed cylinder, a connecting ring is slidably connected to the inner wall of the fixed cylinder, and the outer wall of the connecting ring is slidably connected to the inner wall of the spring sliding ring.

[0010] Preferably, the protective assembly also includes five fixing frames fixedly connected to the inner wall of the fixed cylinder, and the outer walls of the five fixing frames are rotatably connected to a seesaw, and the inner wall of the fixed cylinder is slidably connected to a blocking ring, and the side wall of the blocking ring is fixedly connected to the side wall of the spring sliding ring. When the stirring block moves toward the left inner wall of the conveying pipe, the stirring block will contact the connecting ring and push the connecting ring to move, so that the connecting ring pushes the seesaw to rotate, so that the side of the seesaw in contact with the connecting ring is close to the left inner wall of the conveying pipe, and the other side is away. The side of the seesaw away will push the spring sliding ring and the blocking ring to move, allowing the spring sliding ring to accumulate rebound force.

[0011] Preferably, the protective component also includes five air inlet pipes that are connected through the inner wall of the fixed cylinder, the outer walls of the five air inlet pipes are all slidably connected to the inner wall of the spring sliding ring, five blocking rods are fixedly connected to the inner wall of the fixed cylinder, the outer walls of the five blocking rods are all slidably connected to the inner wall of the spring sliding ring, and a quantity control component is provided on the inner wall of the feed pipe. When the spring sliding ring moves, the spring sliding ring will separate from the air inlet pipe, allowing the blocking rod to enter the spring sliding ring and block the inner wall of the spring sliding ring. At this time, the right side of the spring sliding ring is in a sealed state, which will squeeze the gas in the fixed cylinder, and the squeezed gas will be blocked by the blocking ring, so the gas pressure will increase until the blocking ring is separated from the fixed cylinder, and the gas will be sprayed toward the stirring block, forming a layer of air film between the rice and the stirring block, thereby slowing down the impact of the stirring block on the rice.

[0012] Preferably, the quantity control component includes a fixed sleeve fixedly connected to the inner wall of the feed pipe, a material blocking ring is provided on the inner wall of the feed pipe, the outer wall of the material blocking ring is slidingly connected to the inner wall of the fixed sleeve, the bottom of the material blocking ring is rotatably connected to a roller, and an exhaust component is provided on the outer wall of the conveying pipe.

[0013] Preferably, the quantity control component also includes a ramp block fixedly connected to the side wall of the blocking ring, the side wall of the ramp block is slidably connected to the bottom of roller one, a return spring is fixedly connected to the inner wall of the fixed sleeve, and the side of the return spring away from the fixed sleeve is fixedly connected to the side wall of the blocking ring. When the blocking ring moves, it drives the ramp block to move together, so that the ramp block contacts roller one, pushing roller one to rise, thereby causing the blocking ring to rise and squeezing the return spring to accumulate rebound force. As the blocking ring rises, it will move away from the feed pipe, thereby increasing the gap between the feed pipe and the blocking ring, allowing more rice to flow in.

[0014] Preferably, the exhaust assembly includes an exhaust frame fixedly connected to the outer wall of the conveying pipe, a spring sliding plate slidably connected to the inner wall of the exhaust frame, a connecting rod fixedly connected to the side wall of the material blocking ring, and a roller 2 rotatably connected to the top of the connecting rod. Nine air outlet holes are provided on the inner walls of the conveying pipe and the spring sliding plate. When the material blocking ring rises, the connecting rod will be driven to move, thereby causing roller 2 to rise and contact the top of the spring sliding plate. Roller 2 will lift the spring sliding plate to accumulate rebound force. After the spring sliding plate is lifted, suction will be generated at the bottom of the spring sliding plate, which will be transmitted to the conveying pipe through the air outlet, thereby attracting the gas flow in the conveying pipe.

[0015] A method for using a spiral feeding device for rice processing comprises the following steps:

[0016] S1: Rice transportation: Let the rice enter the transportation pipe through the feeding pipe, then start the motor to drive the spiral auger to rotate and transport the rice;

[0017] S2: Rice separation: When the spiral auger rotates, it also drives the rotating rod to rotate, thereby rotating the stirring block and driving the spring sliding rod to rotate. When the spring sliding rod contacts the protruding position of the concave-convex ring during the rotation process, the spring sliding rod will be squeezed, causing the spring sliding rod to move away from the conveying pipe, so that the spring on the spring sliding rod is stretched and accumulates rebound force. When the spring sliding rod moves, it also drives the stirring block to move toward the left inner wall of the conveying pipe. When the spring sliding rod is separated from the protruding position of the concave-convex ring, the rebound force of the spring sliding rod is released, causing the spring sliding rod and the stirring block to return to their positions. This reciprocating process allows the stirring block to move laterally while rotating, thereby fully separating the rice that has clumped together.

[0018] The present invention has the following beneficial effects:

[0019] (1) When the present invention is used, the rice is allowed to enter the conveying pipe through the feeding pipe, and then the motor is started to drive the spiral auger to rotate to convey the rice. When the spiral auger rotates, it also drives the rotating rod to rotate, thereby causing the stirring block to rotate and driving the spring sliding rod to rotate. When the spring sliding rod contacts the protruding position of the concave-convex ring during the rotation process, the spring sliding rod will be squeezed, causing the spring sliding rod to move away from the conveying pipe, so that the spring on the spring sliding rod is stretched and accumulates rebound force. When the spring sliding rod moves, it will also drive the stirring block to move toward the left inner wall of the conveying pipe. When the spring sliding rod separates from the protruding position of the concave-convex ring, the rebound force of the spring sliding rod will be released, causing the spring sliding rod and the stirring block to return to their original positions. This reciprocating process allows the stirring block to move laterally while rotating, fully The rice that has agglomerated together will be broken up. At the same time, when the stirring block approaches the left inner wall of the conveying pipe, the lateral distance between the push rod and the spring plate will be shortened, the connecting rod will rotate and fold, pushing the spring plate up, driving the blocking rod to rise, so that the blocking rod enters the air jet hole and blocks the air jet hole. At this time, the inner wall of the stirring block is in a sealed state, and the spring plate will squeeze the gas in the stirring block to increase the gas pressure until the blocking rod is separated from the air jet hole, leaving a gap between the two, and the gas will be ejected from the gap onto the rice, further blowing away the rice that has been broken up by the stirring block. By breaking up the rice that has agglomerated together and ejecting gas to further disperse the rice, it is effective to prevent the sticking or blockage caused by rice agglomeration, ensure the smooth flow of the conveying pipe, and ensure stable rice transportation.

[0020] (2) In the present invention, when the stirring block moves toward the left inner wall of the conveying pipe, the stirring block will contact the connecting ring and push the connecting ring to move, so that the connecting ring pushes the seesaw to rotate, so that the side of the seesaw in contact with the connecting ring is close to the left inner wall of the conveying pipe and the other side is away. The side of the seesaw away will push the spring sliding ring and the blocking ring to move, so that the spring sliding ring accumulates rebound force. When the spring sliding ring moves, the spring sliding ring will separate from the air inlet pipe, so that the blocking rod enters the spring sliding ring and blocks the inner wall of the spring sliding ring. At this time, the right side of the spring sliding ring is in a sealed state, which will squeeze the gas in the fixed cylinder. The squeezed gas will be blocked by the blocking ring, so the gas pressure will increase until the blocking ring is separated from the fixed cylinder. The gas will be sprayed toward the stirring block, forming a layer of air film between the rice and the stirring block, thereby slowing down the impact of the stirring block on the rice and effectively preventing the rice from being broken due to excessive impact force.

[0021] (3) In the present invention, when the blocking ring moves, it drives the inclined plane block to move together, so that the inclined plane block contacts the roller 1, pushes the roller 1 to rise, thereby causing the blocking ring to rise and squeeze the reset spring to accumulate rebound force. As the blocking ring rises, it will move away from the feed pipe, thereby increasing the gap between the feed pipe and the blocking ring, allowing more rice to flow in. When the spring sliding ring returns to its position, the blocking ring and the inclined plane block will also return to their positions, releasing the obstruction to the roller 1. The reset spring releases the rebound force, causing the blocking ring to return to its position, reducing the gap between the feed pipe and the blocking ring, thereby reducing the amount of rice entering the conveying pipe, effectively controlling the amount of rice entering, and effectively preventing the rice from piling up near the stirring block. When the stirring block rotates, the accumulated rice will be squeezed, which may cause the rice to break.

[0022] (4) When the material blocking ring of the present invention rises, it will drive the connecting rod to move, so that the second roller will rise and contact the top of the spring sliding plate. The second roller will lift the spring sliding plate to accumulate rebound force. After the spring sliding plate is lifted, the bottom of the spring sliding plate will generate suction, which will be transmitted to the conveying pipe through the air outlet, and will attract the gas flow in the conveying pipe. As the spring sliding plate continues to move, the left and right sides of the spring sliding plate will be separated from the exhaust frame, and the gas in the conveying pipe will be quickly discharged through the exhaust frame, which effectively prevents the wet rice from being separated. After that, the separated moisture is difficult to be discharged quickly, which may cause the rice to agglomerate again during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] For example 1, please refer to Figure 1 - Figure 5 The present invention is a spiral feeding device for rice processing, comprising a conveying pipe 1, a motor 11 is fixedly connected to the side wall of the conveying pipe 1, a spiral auger 12 is rotatably connected to the inner wall of the conveying pipe 1, the side wall of the spiral auger 12 is fixedly connected to the output end of the side wall of the motor 11, a feed pipe 13 is fixedly connected to the outer wall of the conveying pipe 1, and a discharge pipe 14 is fixedly connected to the outer wall of the conveying pipe 1;

[0037] The stirring mechanism 2 includes a rotating rod 21, a stirring block 22 for stirring the rice in the conveying pipe 1, a spring sliding rod 23, a concave-convex ring 24, and a separation component 3 for separating the rice in the conveying pipe 1;

[0038] The side wall of the rotating rod 21 is fixedly connected to the side wall of the spiral auger 12, the number of the stirring blocks 22 is five, the outer walls of the five stirring blocks 22 are all slidably connected to the inner wall of the rotating rod 21, the outer wall of the spring sliding rod 23 is slidably connected to the inner wall of the rotating rod 21, the side wall of the concave-convex ring 24 is fixedly connected to the side wall of the conveying pipe 1, the side walls of the five stirring blocks 22 are all fixedly connected to the side walls of the spring sliding rod 23, the rice is allowed to enter the conveying pipe 1 through the feeding pipe 13, and then the motor 11 is started to drive the spiral auger 12 to rotate When the spiral auger 12 rotates, it also drives the rotating rod 21 to rotate, thereby rotating the stirring block 22, driving the spring sliding rod 23 to rotate. When the spring sliding rod 23 contacts the convex position of the concave-convex ring 24 during the rotation process, the spring sliding rod 23 will be squeezed, so that the spring sliding rod 23 is away from the conveying pipe 1, so that the spring on the spring sliding rod 23 is stretched, accumulating rebound force, and when the spring sliding rod 23 moves, it will also drive the stirring block 22 to move toward the left inner wall of the conveying pipe 1. When the spring sliding rod 23 contacts the concave-convex ring 24, the spring sliding rod 23 will be squeezed, so that the spring sliding rod 23 is away from the conveying pipe 1, so that the spring on the spring sliding rod 23 is stretched, accumulating rebound force, and when the spring sliding rod 23 moves, it will also drive the stirring block 22 to move toward the left inner wall of the conveying pipe 1. When the protruding position of the convex ring 24 is separated, the rebound force of the spring sliding rod 23 is released, so that the spring sliding rod 23 and the stirring block 22 return to their original positions. In this way, the stirring block 22 can move laterally while rotating, and fully break up the rice that has agglomerated together. At the same time, when the stirring block 22 approaches the left inner wall of the conveying pipe 1, the lateral distance between the pushing rod 32 and the spring plate 31 is shortened, and the connecting rod 33 is rotated and folded, pushing the spring plate 31 upward, driving the blocking rod 34 to rise, so that the blocking rod 34 enters the air injection hole 35, and the rice is discharged. The air jet hole 35 is blocked. At this time, the inner wall of the stirring block 22 is in a sealed state, and the spring plate 31 will squeeze the gas in the stirring block 22 to increase the gas pressure until the blocking rod 34 is separated from the air jet hole 35, leaving a gap between the two. The gas will be ejected from the gap onto the rice, further dispersing the rice that has been broken up by the stirring block 22. By breaking up the clumped rice and ejecting gas to further disperse the rice, it is effectively prevented from getting stuck or blocked due to rice agglomeration, ensuring the smooth flow of the conveying pipe 1 and enabling stable rice transportation.

[0039] For example 2, please refer to Figure 6 - Figure 9 The present invention is a spiral feeding device for rice processing. On the basis of embodiment 1, the separation component 3 includes a spring plate 31 slidably connected to the inner wall of the stirring block 22, and the inner walls of the five stirring blocks 22 are all slidably connected to push rods 32. The side walls of the five push rods 32 are all rotatably connected to connecting rods 33. The inner walls of the five connecting rods 33 are rotatably connected to the bottoms of the five spring plates 31, and the side walls of the five push rods 32 are in contact with the inner wall of the conveying pipe 1.

[0040] The separation assembly 3 also includes several blocking rods 34 fixedly connected to the top of the spring plate 31, and several air injection holes 35 are opened on the inner walls of the five stirring blocks 22. The outer walls of the several blocking rods 34 are slidably connected to the inner walls of the several air injection holes 35, and a protective assembly 4 is provided on the inner wall of the conveying pipe 1.

[0041] The protective component 4 includes a fixed cylinder 41 fixedly connected to the inner wall of the conveying pipe 1, a spring sliding ring 42 is slidably connected to the inner wall of the fixed cylinder 41, a connecting ring 43 is slidably connected to the inner wall of the fixed cylinder 41, and the outer wall of the connecting ring 43 is slidably connected to the inner wall of the spring sliding ring 42.

[0042] The protective assembly 4 also includes five fixing frames 44 fixedly connected to the inner wall of the fixed cylinder 41, and the outer walls of the five fixing frames 44 are rotatably connected to a rocker 45. A blocking ring 46 is slidably connected to the inner wall of the fixed cylinder 41, and the side wall of the blocking ring 46 is fixedly connected to the side wall of the spring sliding ring 42. When the stirring block 22 moves toward the left inner wall of the conveying pipe 1, the stirring block 22 will contact the connecting ring 43, pushing the connecting ring 43 to move, so that the connecting ring 43 pushes the rocker 45 to rotate, so that the side of the rocker 45 in contact with the connecting ring 43 is close to the left inner wall of the conveying pipe 1, and the other side is away. The side of the rocker 45 away will push the spring sliding ring 42 and the blocking ring 46 to move, allowing the spring sliding ring 42 to accumulate rebound force.

[0043] The protective component 4 also includes five air inlet pipes 47 that are connected to the inner wall of the fixed cylinder 41. The outer walls of the five air inlet pipes 47 are all slidably connected to the inner wall of the spring sliding ring 42. Five blocking rods 48 are fixedly connected to the inner wall of the fixed cylinder 41. The outer walls of the five blocking rods 48 are all slidably connected to the inner wall of the spring sliding ring 42. A quantity control component 5 is provided on the inner wall of the feed pipe 13. When the spring sliding ring 42 moves, the spring sliding ring 42 will separate from the air inlet pipe 47, allowing the blocking rod 48 to enter the spring sliding ring 42 and block the inner wall of the spring sliding ring 42. At this time, the right side of the spring sliding ring 42 is in a sealed state, which will squeeze the gas in the fixed cylinder 41. The squeezed gas will be blocked by the blocking ring 46, so the gas pressure will increase until the blocking ring 46 is separated from the fixed cylinder 41, and the gas will be sprayed toward the stirring block 22, forming a layer of air film between the rice and the stirring block 22, thereby slowing down the impact of the stirring block 22 on the rice.

[0044] The quantity control component 5 includes a fixed sleeve 51 fixedly connected to the inner wall of the feed pipe 13, a material blocking ring 52 is provided on the inner wall of the feed pipe 13, the outer wall of the material blocking ring 52 is slidingly connected to the inner wall of the fixed sleeve 51, the bottom of the material blocking ring 52 is rotatably connected to a roller 521, and an exhaust component 6 is provided on the outer wall of the conveying pipe 1.

[0045] The quantity control component 5 also includes a ramp block 53 fixedly connected to the side wall of the blocking ring 46, the side wall of the ramp block 53 is slidably connected to the bottom of the roller 1 521, and a return spring 54 is fixedly connected to the inner wall of the fixed sleeve 51. The side of the return spring 54 away from the fixed sleeve 51 is fixedly connected to the side wall of the blocking ring 52. When the blocking ring 46 moves, it drives the ramp block 53 to move together, so that the ramp block 53 contacts the roller 1 521, pushing the roller 1 521 to rise, thereby causing the blocking ring 52 to rise and squeezing the return spring 54 to accumulate rebound force. As the blocking ring 52 rises, it will move away from the feed pipe 13, thereby increasing the gap between the feed pipe 13 and the blocking ring 52, allowing more rice to flow in.

[0046] The exhaust assembly 6 includes an exhaust frame 61 fixedly connected to the outer wall of the conveying pipe 1, and a spring sliding plate 62 is slidably connected to the inner wall of the exhaust frame 61. A connecting rod 63 is fixedly connected to the side wall of the blocking ring 52, and the top of the connecting rod 63 is rotatably connected to roller 2 64. Nine air outlet holes 65 are provided on the inner walls of the conveying pipe 1 and the spring sliding plate 62. When the blocking ring 52 rises, it will drive the connecting rod 63 to move, so that roller 2 64 rises and contacts the top of the spring sliding plate 62. Roller 2 64 will lift the spring sliding plate 62 to accumulate rebound force. After the spring sliding plate 62 is lifted, suction will be generated at the bottom of the spring sliding plate 62, which will be transmitted to the conveying pipe 1 through the air outlet 65, thereby attracting the gas flow in the conveying pipe 1.

[0047] There is no limit on the number of the above components, and relevant technicians in this field can freely set them according to actual needs, as long as the above components are installed in the corresponding component connection positions.

[0048] The method for using the spiral feeding equipment for rice processing includes the following steps:

[0049] S1: Rice conveying: Rice is fed into the conveying pipe 1 through the feed pipe 13, and then the motor 11 is started to drive the auger 12 to rotate and convey the rice;

[0050] S2: Rice separation: When the spiral auger 12 rotates, it also drives the rotating rod 21 to rotate, thereby rotating the stirring block 22 and driving the spring sliding rod 23 to rotate. When the spring sliding rod 23 contacts the protruding position of the concave-convex ring 24 during the rotation process, the spring sliding rod 23 will be squeezed, so that the spring sliding rod 23 is away from the conveying pipe 1, so that the spring on the spring sliding rod 23 is stretched, accumulating rebound force. When the spring sliding rod 23 moves, it also drives the stirring block 22 to move toward the left inner wall of the conveying pipe 1. When the spring sliding rod 23 separates from the protruding position of the concave-convex ring 24, the rebound force of the spring sliding rod 23 is released, causing the spring sliding rod 23 and the stirring block 22 to return to their original position. This reciprocating process allows the stirring block 22 to move laterally while rotating, thereby fully separating the rice that has agglomerated together.

[0051] A specific application of this embodiment is as follows: when the present invention is used, the rice is allowed to enter the conveying pipe 1 through the feeding pipe 13, and then the motor 11 is started to drive the spiral screw dragon 12 to rotate to convey the rice. When the spiral screw dragon 12 rotates, it will also drive the rotating rod 21 to rotate, thereby causing the stirring block 22 to rotate, driving the spring sliding rod 23 to rotate. When the spring sliding rod 23 contacts the convex position of the concave-convex ring 24 during the rotation process, the spring sliding rod 23 will be squeezed, causing the spring sliding rod 23 to move away from the conveying pipe 1, so that the spring on the spring sliding rod 23 is stretched, accumulating rebound force, and when the spring sliding rod 23 moves, it will also drive the stirring block 22 to move toward the left inner wall of the conveying pipe 1. When the spring sliding rod 23 separates from the convex position of the concave-convex ring 24, the rebound force of the spring sliding rod 23 is released, causing the spring sliding rod 23 and the stirring block 22 to return to their original position. This reciprocating process allows the stirring block 22 to move laterally while rotating, fully agglomerating the rice. The rice that has been agglomerated is broken up. At the same time, when the stirring block 22 approaches the left inner wall of the conveying pipe 1, the lateral distance between the pushing rod 32 and the spring plate 31 is shortened, and the connecting rod 33 is rotated and folded, pushing the spring plate 31 upward, driving the blocking rod 34 to rise, so that the blocking rod 34 enters the air-jet hole 35 and blocks the air-jet hole 35. At this time, the inner wall of the stirring block 22 is in a sealed state, and the spring plate 31 squeezes the gas in the stirring block 22 to increase the gas pressure until the blocking rod 34 is separated from the air-jet hole 35, leaving a gap between the two. The gas will be sprayed onto the rice from the gap, further blowing away the rice that has been broken up by the stirring block 22. By breaking up the rice that has agglomerated together and spraying gas to further disperse the rice, it is effectively prevented from being stuck or blocked due to rice agglomeration, ensuring the unobstructed flow of the conveying pipe 1 and being able to stably convey the rice until the rice is conveyed to the position of the discharge pipe 14 and discharged through the discharge pipe 14.

[0052] When the stirring block 22 returns to its original position, the rebound force of the spring plate 31 is released, allowing the spring plate 31 to return to its original position, so that the blocking rod 34 returns to its original position and separates from the air injection hole 35, leaving a gap between the two, and external air will enter the stirring block 22 through the gap;

[0053] Secondly, when the stirring block 22 moves toward the left inner wall of the delivery pipe 1, the stirring block 22 will contact the connecting ring 43, pushing the connecting ring 43 to move, so that the connecting ring 43 pushes the seesaw 45 to rotate, so that the side of the seesaw 45 in contact with the connecting ring 43 is close to the left inner wall of the delivery pipe 1, and the other side is away. The side of the seesaw 45 away from the spring sliding ring 42 and the blocking ring 46 will move, allowing the spring sliding ring 42 to accumulate rebound force. When the spring sliding ring 42 moves, the spring sliding ring 42 will separate from the intake pipe 47. The blocking rod 48 enters the spring sliding ring 42 and blocks the inner wall of the spring sliding ring 42. At this time, the right side of the spring sliding ring 42 is in a sealed state, which squeezes the gas in the fixed cylinder 41. The squeezed gas is blocked by the blocking ring 46, so the gas pressure increases until the blocking ring 46 separates from the fixed cylinder 41. The gas is then ejected toward the stirring block 22, forming an air film between the rice and the stirring block 22, thereby reducing the impact of the stirring block 22 on the rice and effectively preventing the rice from being broken due to excessive impact force.

[0054] When the stirring block 22 is separated from the connecting ring 43, the resilience of the spring sliding ring 42 is released, allowing the spring sliding ring 42 to contact the air inlet pipe 47 again and separate from the blocking rod 48, so that a gap leaks between the blocking rod 48 and the spring sliding ring 42, and external air enters the fixed cylinder 41 through the air inlet pipe 47;

[0055] When the spring sliding ring 42 returns to its original position, the blocking ring 46 and the inclined surface block 53 will also return to their original position, releasing the obstruction to roller 1 521, and the return spring 54 will release its rebound force, causing the blocking ring 52 to return to its original position, narrowing the gap between the feed pipe 13 and the blocking ring 52, thereby reducing the amount of rice entering the conveying pipe 1, effectively controlling the amount of rice entering, and effectively preventing the accumulation of rice near the stirring block 22. When the stirring block 22 rotates, the accumulated rice will be squeezed, which may cause the rice to break.

[0056] Secondly, when the material blocking ring 52 rises, it will drive the connecting rod 63 to move, so that the second roller 64 rises and contacts the top of the spring sliding plate 62. The second roller 64 will lift the spring sliding plate 62 to accumulate resilience. After the spring sliding plate 62 is lifted, suction will be generated at the bottom of the spring sliding plate 62, which will be transmitted to the conveying pipe 1 through the air outlet 65, thereby attracting the gas flow in the conveying pipe 1. As the spring sliding plate 62 continues to move, the left and right sides of the spring sliding plate 62 will be separated from the exhaust frame 61, and the gas in the conveying pipe 1 will be quickly discharged through the exhaust frame 61, effectively preventing the wet rice from being separated. The separated moisture is difficult to be discharged quickly, which may cause the rice to regroup during transportation.
