Description

Technical Field

[0001] This invention relates to the field of micro-volume dehydration grain suction machine technology, specifically a micro-volume dehydration grain suction machine with a deformable suction nozzle. Background Technology

[0002] The micro-volume dehydration grain suction machine is a modern device that uses the principle of negative pressure pneumatic conveying to generate strong suction and transport granular materials from one place to another through a closed pipeline. Because of its functions such as high-efficiency conveying, micro-volume dehydration and cleaning, and environmental protection, it is often used in warehousing and logistics, grain processing, feed and brewing industries, and grain, oil and food processing.

[0003] In existing technologies, the suction nozzles of micro-dehydration grain suction machines are mostly fixed or can only swing within a small range, and cannot achieve continuous rotation. This results in obvious suction dead zones during operation, especially for residual grain in the four corners of the truck bed and the edges of the walls, which are difficult to effectively suck up and often require manual assistance to clean, which is time-consuming and labor-intensive. In addition, after the fixed suction nozzle is inserted into the grain pile, it is easy to have uneven suction or suction on one side, resulting in low airflow utilization and unstable conveying efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the problem that most micro-volume dehydration grain suction machines have fixed or limited-range oscillation nozzles that cannot achieve continuous rotation, resulting in obvious suction dead zones during operation. In particular, it is difficult to effectively suck up residual grain in the four corners of the truck bed and along the edges of the walls, often requiring manual assistance for cleaning, which is time-consuming and labor-intensive. Furthermore, fixed nozzles, after being inserted into the grain pile, cannot actively change the direction of the suction port, which easily leads to biased suction or empty suction on one side, resulting in low airflow utilization and unstable conveying efficiency. Therefore, this invention proposes a micro-volume dehydration grain suction machine with a deformable suction nozzle.

[0009] In a preferred embodiment of the present invention, a pair of cleaning rods are fixedly connected to the outer wall of the circular rod; the outer walls of the pair of cleaning rods are in contact with the inner wall of the circular tube; the pair of cleaning rods are matched with a set of striking rods.

[0010] In a preferred embodiment of the present invention, the cleaning rod includes a square shell and a rod body; the outer side wall of the rod body is slidably connected to the inner side wall of the square shell; a spring is fixedly connected to one side of the inner wall of the square shell, and one end of the outer wall of the spring is fixedly connected to one end of the outer wall of the rod body; a damper is provided at the spring.

[0011] In a preferred embodiment of the present invention, a set of vibrating rods is fixedly connected to the outer wall of the rotating rod; a vibrating ball is fixedly connected to one end of the outer wall of the vibrating rod; and the set of vibrating balls are all fitted into the circular tube.

[0012] In a preferred embodiment of the present invention, the outer wall of the circular tube is rotatably connected to a pair of linkage rods via a pair of square five-pinion rods; the outer walls of both the linkage rods and the rotating rods are fixedly connected to second sprockets, and a set of second sprockets are connected to each other via a second chain; the outer wall of the linkage rod is fixedly connected to a set of auxiliary rods; one end of the outer wall of the auxiliary rod is fixedly connected to an auxiliary ball; the auxiliary ball fits into the circular tube.

[0013] In a preferred embodiment of the present invention, a fifth bevel gear is fixedly connected to one end of the circular rod penetrating the outer wall of the shielding shell; a pair of first circular rods are rotatably connected to the inner side wall of the circular tube; a sixth bevel gear is fixedly connected to one end of the outer wall of each pair of first circular rods, and the pair of sixth bevel gears mesh with the fifth bevel gear; a set of dispersing rods is fixedly connected to the outer side wall of the first circular rod; a sealing shell is rotatably connected to the outer side wall of the circular rod, and the sealing shell is rotatably connected to the pair of first circular rods; the fifth bevel gear and the pair of sixth bevel gears are both located inside the sealing shell.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The drive device drives the rotating shaft to rotate, which in turn drives the first gear to rotate. Because the first gear meshes with the first ring rack, the first gear moves along the tooth groove of the first ring rack when it rotates, thereby driving the drive device and the auxiliary pipe to rotate. The auxiliary pipe drives the grain suction nozzle to rotate, so that the grain suction nozzle is in a dynamic sweeping state, covering all directions of the grain pile. This eliminates the blind spots in the traditional fixed suction nozzle, enabling continuous and uniform grain suction. This increases the suction range of the grain suction nozzle and makes the operation of this application more flexible. The continuous rotation can effectively prevent the grain from accumulating or bridging at the suction port, avoiding the phenomenon of empty suction or pipe blockage caused by local empty suction. This makes the conveying process more stable and smooth, and improves the operating efficiency.

[0015] 2. When the pair of expansion shells move to both sides, they drive the connecting rods to move. Because the connecting rods and connecting blocks are hinged, the connecting rods drive the connecting blocks to move. As the connecting blocks slide on the air guide plates, they pull the air guide plates, changing their angle until the pair of air guide plates form a V-shape. At this time, the pair of air guide plates block the center of the shell, causing the air force to move along the air guide plates to both sides. When the expansion shells open, the air force draws grain from both sides; when the expansion shells retract, the air force draws grain from the center. When the expansion shells are in a half-open state, the air guide plates have a tilted transition angle, creating a gradient distribution of air force between the center and the sides. This ensures the efficiency of the main grain suction while also providing auxiliary suction in the edge areas, achieving dynamic airflow distribution during the grain suction process. Sometimes the grain is sucked from the center, and sometimes from both sides, making the grain suction more uniform. At the same time, when cleaning narrow areas such as the corners of the truck bed, the tilt angle of the air guide plates can guide the airflow to form a directional vortex, drawing the remaining grain in the gaps to the suction port, reducing the amount of manual cleaning.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1:

[0021] Please see Figures 1-9 As shown, a micro-dehydration grain suction machine with a deformable suction nozzle includes a grain suction machine body 1; a conveying pipe 2 is provided at the output end of the grain suction machine body 1; a circular pipe 3 is fixedly connected to one end of the conveying pipe 2; an auxiliary pipe 4 is rotatably connected to one end of the outer wall of the circular pipe 3; a grain suction nozzle 5 is fixedly connected to one end of the outer wall of the auxiliary pipe 4; a driving device 6 is fixedly connected to the outer wall of the auxiliary pipe 4 through a fixing block; a rotating shaft 7 is provided at the output end of the driving device 6; a first gear 8 is fixedly connected to the outer wall of the rotating shaft 7; a first annular rack 9 is fixedly connected to the outer wall of the circular pipe 3 through a connecting plate, and the first gear 8 meshes with the first annular rack 9.

[0022] The drive device 6 drives the rotating shaft 7 to rotate, which in turn drives the first gear 8 to rotate. Since the first gear 8 meshes with the first ring rack 9, it moves along the tooth groove of the first ring rack 9 as it rotates, thereby driving the drive device 6 and the auxiliary pipe 4 to rotate. The auxiliary pipe 4 drives the grain suction nozzle 5 to rotate, putting the grain suction nozzle 5 in a dynamic sweeping state, covering all directions of the grain pile. This eliminates the blind spots commonly found in traditional fixed suction nozzles, enabling continuous and uniform grain suction. This increases the suction range of the grain suction nozzle 5 and makes the operation of this application more flexible. Continuous rotation can effectively prevent grain from accumulating or bridging at the suction port, avoiding empty suction or pipe blockage caused by localized empty suction. This makes the conveying process smoother and more efficient.

[0023] A rotating rod 19 is rotatably connected to the outer wall of the circular tube 3 via a block 3; a fourth annular rack 20 is fixedly connected to the outer wall of the auxiliary tube 4; a fourth gear 21 is fixedly connected to one end of the outer wall of the rotating rod 19, and the fourth gear 21 meshes with the fourth annular rack 20; a first through groove 22 is opened on the outer wall of the circular tube 3; a shielding shell 23 is fixedly connected to the inner wall of the first through groove 22; a circular rod 24 is rotatably connected to one side of the outer wall of the shielding shell 23, and the circular rod 24 penetrates the shielding shell 23; a first sprocket 25 is fixedly connected to the outer wall of the end of the circular rod 24 located inside the shielding shell 23 and the outer wall of the rotating rod 19, and a pair of first sprockets 25 are connected by a first chain 26; a set of striking rods 27 are fixedly connected to the outer wall of the circular rod 24.

[0024] The rotation of the auxiliary pipe 4 drives the fourth annular rack 20 to rotate. Because the fourth gear 21 meshes with the fourth annular rack 20, the rotation of the fourth annular rack 20 drives the fourth gear 21 to rotate. The fourth gear 21 drives the rotating rod 19 to rotate. The rotating rod 19 drives the circular rod 24 to rotate via the first sprocket 25 and the first chain 26. The circular rod 24 drives a set of striking rods 27 to rotate, causing any sticky material entering the suction to be broken up by the striking rods 27. This enables the present application to actively break up easily agglomerated, damp, or sticky materials. The dispersing ability is such that when there are clumps of material stuck together in the suction, the striking rod 27 mechanically intervenes before the material enters the main conveying pipe. The impact force generated by the rotation breaks up the agglomerates, effectively avoiding the problem of conveying interruption or sudden increase in fan load caused by large pieces of material clogging the pipe. This not only improves the continuity and stability of the conveying process, but also increases the contact area between the material and the airflow, which is conducive to more uniform and efficient subsequent micro-dehydration. At the same time, it reduces the local blockage of the suction port caused by material caking and reduces the frequency of manual cleaning.

[0025] The suction nozzle 5 includes a housing 501 and an extension shell 502; square plates 10 are fixedly connected to opposite sides of the outer wall of the housing 501; the outer side walls of a pair of extension shells 502 are slidably connected to the inner side walls of the two sides of the housing 501; a double-segment threaded rod 11 is rotatably connected to one side of the outer wall of the housing 501 via a block; a pair of threaded blocks 12 are threadedly connected to the outer side wall of the double-segment threaded rod 11, and one end of the outer wall of the pair of threaded blocks 12 is fixedly connected to one side of the outer wall of the pair of extension shells 502; a second bevel gear 13 is fixedly connected to one end of the outer wall of the rotating shaft 7; a third bevel gear 14 is fixedly connected to the outer side wall of the double-segment threaded rod 11, and the second bevel gear 13 meshes with the third bevel gear 14; a protective shell 15 is fixedly connected to one side of the outer wall of the housing 501, and the double-segment threaded rod 11, the second bevel gear 13 and the third bevel gear 14 are all located inside the protective shell 15.

[0026] While the drive device 6 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the second bevel gear 13 to rotate. Because the second bevel gear 13 meshes with the third bevel gear 14, the second bevel gear 13 drives the third bevel gear 14 to rotate. The third bevel gear 14 drives the double-segment threaded rod 11 to rotate. Since the double-segment threaded rod 11 is threadedly connected to a pair of threaded blocks 12, the rotation of the double-segment threaded rod 11 causes the pair of threaded blocks 12 to move simultaneously towards the center or to both sides. This causes the threaded blocks 12 to move the expansion shell 502. The forward and reverse rotation of the drive device 6 not only causes the suction nozzle 5 to rotate but also deforms it, increasing the suction range. This allows the suction nozzle 5 to dynamically adjust its suction width during the rotational sweeping process. When the drive device 6 rotates forward, the double-segment threaded rod 11... The screw blocks 12 move to both sides, and the expansion shell 502 slides outward along the side wall of the shell 501, increasing the lateral span of the suction port and covering a wider grain pile area. When reversed, the screw blocks 12 move towards the center, and the expansion shell 502 retracts and resets, adapting to the suction needs of narrow corners or dense grain piles. This allows the suction nozzle 5 to quickly sweep and suck up large areas of grain piles, and to accurately clean up residues in narrow spaces such as the corners of the truck bed. This effectively solves the problem of insufficient adaptability of traditional suction nozzles in different operating scenarios. In addition, the protective shell 15 protects the double-segment screw rod 11, the second bevel gear 13, and the third bevel gear 14, preventing external dust or materials from contacting the double-segment screw rod 11, the second bevel gear 13, and the third bevel gear 14, making the operation of this application less susceptible to external interference.

[0027] A set of vibrating rods 29 are fixed to the outer wall of the rotating rod 19; a vibrating ball 30 is fixed to one end of the outer wall of the vibrating rod 29; the set of vibrating balls 30 are all fitted with the circular tube 3.

[0028] The rotating rod 19 rotates, driving a set of vibrating rods 29 to rotate. The vibrating rods 29 drive the vibrating balls 30 to rotate, causing the vibrating balls 30 to strike the circular tube 3, generating vibration. This effectively breaks the adhesion between the material and the inner wall of the circular tube 3. Especially for grain particles with high moisture content or stickiness, it can promote their detachment from the tube wall. This, combined with the scraping action of the cleaning rod 28, forms a synergistic cleaning effect, ensuring that the material is transported evenly under the action of airflow.

[0029] A pair of cleaning rods 28 are fixed to the outer wall of the circular rod 24; the outer walls of the pair of cleaning rods 28 are in contact with the inner wall of the circular tube 3; the pair of cleaning rods 28 are matched with a set of striking rods 27.

[0030] The rotation of the circular rod 24 drives the cleaning rod 28 to rotate. The rotation of the cleaning rod 28 cleans the inner wall of the circular pipe 3, scraping off the material adhering to the inner wall of the circular pipe 3. This prevents the scale formed by long-term accumulation from affecting the inner diameter of the pipe, thereby maintaining a stable cross-sectional area of ​​the airflow channel. When the cleaning rod 28 rotates at high speed with the circular rod 24, it can not only scrape off the statically adhering material, but also throw the scraped fine particles into the mainstream airflow area through centrifugal force, and transport them along with the conveying airflow. This not only ensures the output environment of the circular pipe 3, but also reduces material waste. Combined with the breaking function of the striking rod 27, it reduces the risk of pipe blockage and extends the continuous operation time.

[0031] A pair of air guide plates 16 are hinged at the center of the top of the inner wall of the housing 501; a pair of connecting rods 17 are fixed to opposite sides of the inner walls of the two extended housings 502; a connecting block 18 is hinged to one end of the outer wall of each pair of connecting rods 17; and a pair of connecting blocks 18 are slidably connected to one side of the outer wall of the pair of air guide plates 16.

[0032] When the pair of expansion shells 502 move to both sides, they drive the connecting rod 17 to move. Since the connecting rod 17 and the connecting block 18 are hinged, the connecting rod 17 drives the connecting block 18 to move. As the connecting block 18 slides on the air guide plate 16, it pulls the air guide plate 16, causing the air guide plate 16 to change its angle until the pair of air guide plates 16 form a V-shape. At this time, the pair of air guide plates 16 block the center of the shell 501, causing the air force to move along the air guide plate 16 to both sides. When the expansion shells 502 open, the air force draws in grain from both sides. When the expansion shells 502 retract, the air force... The force draws grain from the center. When the expansion shell 502 is in a half-open state, the air guide plate 16 is tilted at a transition angle, so that the wind force forms a gradient distribution between the center and the sides. This ensures the efficiency of the main grain suction and also provides auxiliary suction for the edge areas, realizing dynamic airflow distribution during the grain suction process. Sometimes the grain is sucked from the center, and sometimes from the sides, making the grain suction more uniform. At the same time, when cleaning narrow areas such as the corners of the truck bed, the tilt angle of the air guide plate 16 can guide the airflow to form a directional vortex, which can suck up the remaining grain in the gaps to the suction port, reducing the amount of manual auxiliary cleaning work.

[0033] The outer wall of the circular tube 3 is rotatably connected to a pair of linkage rods 31 via a pair of square five-pins; the outer walls of the pair of linkage rods 31 and the rotating rod 19 are both fixedly connected to a second sprocket 32, and a set of second sprockets 32 are connected to each other via a second chain 33; the outer wall of the linkage rod 31 is fixedly connected to a set of auxiliary rods 34; one end of the outer wall of the auxiliary rod 34 is fixedly connected to an auxiliary ball 35; the auxiliary ball 35 fits into the circular tube 3.

[0034] The rotating rod 19 drives a pair of linkage rods 31 to rotate via the second sprocket 32 ​​and the second chain 33. The linkage rods 31 drive the auxiliary rod 34 to rotate, and the auxiliary rod 34 drives the auxiliary ball 35 to rotate. This causes the auxiliary ball 35 to strike the outer wall of the circular tube 3, generating vibration. Together with the vibrating ball 30, this forms three vibration points distributed in a circular array. The vibrating ball 30 and the auxiliary ball 35 impact the circular tube 3 from different angles, ensuring that the circular tube 3 is subjected to uniform force. The vibration waves form superimposed interference within the tube wall, effectively avoiding the vibration dead zones and uneven energy distribution problems that are prone to occur with a single vibration source. This improves the anti-sticking and anti-clogging effect. Furthermore, since the rotating rod 19 and the pair of linkage rods 31 share the same power source, the overall energy consumption is lower than the sum of multiple independent vibrators, resulting in energy-saving effects.

[0035] The cleaning rod 28 includes a square shell 281 and a rod body 282; the outer side wall of the rod body 282 is slidably connected to the inner side wall of the square shell 281; a spring 283 is fixedly connected to one side of the inner wall of the square shell 281, and one end of the outer wall of the spring 283 is fixedly connected to one end of the outer wall of the rod body 282; a damper is provided at the spring 283.

[0036] The cleaning rod 28, comprising a square shell 281 and a rod body 282, utilizes the elastic force of a spring 283 to compress the rod body 282, ensuring that one side of the outer wall of the rod body 282 remains in contact with the inner wall of the circular tube 3. This prevents the cleaning rod 28 from scratching the tube wall or deforming the rod body 282 due to rigid contact. The damper provides controllable buffer resistance, preventing the spring 283 from bouncing violently when the equipment starts or stops or when the speed changes, thus maintaining a stable and flexible contact between the rod body 282 and the tube wall. This ensures the continuity of the cleaning effect, reduces the rate of mechanical wear, and even when the cleaning rod 28 wears, the elastic force of the spring 283 still keeps the rod body 282 in contact with the inner wall of the circular tube 3. This eliminates the need for frequent adjustments or replacements of the cleaning rod 28 during long-term use, reducing maintenance costs. At the same time, it ensures that the inner wall of the circular tube 3 remains clean, providing a guarantee for stable airflow and subsequent micro-dehydration.

[0037] Example 2:

[0038] Please see Figure 7 and Figure 10 As shown, a fifth bevel gear 36 is fixedly connected to one end of a circular rod 24 that penetrates the outer wall of the shielding shell 23; a pair of first circular rods 37 are rotatably connected to the inner wall of the circular tube 3; a sixth bevel gear 38 is fixedly connected to one end of the outer wall of each pair of first circular rods 37, and both sixth bevel gears 38 mesh with the fifth bevel gear 36; a set of dispersing rods 39 are fixedly connected to the outer wall of the first circular rods 37; a sealing shell 40 is rotatably connected to the outer wall of the circular rod 24, and the sealing shell 40 is rotatably connected to the pair of first circular rods 37; the fifth bevel gear 36 and the pair of sixth bevel gears 38 are both located inside the sealing shell 40.

[0039] The circular rod 24 drives the fifth bevel gear 36 to rotate. Since both sixth bevel gears 38 mesh with the fifth bevel gear 36, the rotation of the fifth bevel gear 36 drives the first circular rod 37 to rotate via the sixth bevel gears 38, which in turn drives the two sets of dispersing rods 39 to rotate. Together with the impact rods, these rods break up the adhered materials. Because the impact rods 27 and dispersing rods 39 strike laterally and longitudinally respectively, they form a three-dimensional, intersecting breaking network, providing multi-dimensional intervention to material clumps. The laterally rotating impact rods 27 primarily target and break up larger clumps, while the longitudinally rotating dispersing rods 39 further refine the initially broken material. Through the crisscrossing shearing and impact forces, irregular clumps that are difficult to handle with traditional single-direction impacts are thoroughly decomposed into uniform particles. This results in more complete material dispersion and a more uniform particle size distribution, not only avoiding the risk of pipe blockage caused by large pieces of material but also increasing the contact area between the material and the hot airflow in the subsequent micro-dehydration stage, improving dehydration uniformity and efficiency.

[0040] In use, the present invention drives the rotating shaft 7 to rotate via the driving device 6, which in turn drives the first gear 8 to rotate. Since the first gear 8 meshes with the first annular rack 9, the first gear 8 moves along the tooth groove of the first annular rack 9 as it rotates, thereby driving the driving device 6 and the auxiliary pipe 4 to rotate. The auxiliary pipe 4 drives the grain suction nozzle 5 to rotate, so that the grain suction nozzle 5 is in a dynamic sweeping state, covering all directions of the grain pile, eliminating the blind spots in the traditional fixed suction nozzle, and performing continuous and uniform grain suction.

[0041] The auxiliary pipe 4 drives the fourth annular rack 20 to rotate, which in turn drives the fourth gear 21 to rotate. The fourth gear 21 drives the rotating rod 19 to rotate. The rotating rod 19 drives the circular rod 24 to rotate via the first sprocket 25 and the first chain 26. The circular rod 24 drives a set of striking rods 27 to rotate, causing any sticky material in the suction to be broken up by the striking rods 27 upon entry. This gives the present application the ability to actively break up easily agglomerated, damp, or sticky materials. When there are sticky clumps in the suction material, the striking rods 27 mechanically intervene before the material enters the main conveying pipe 2. The striking force generated by the rotation breaks up the agglomerates, effectively avoiding the problem of conveying interruption or sudden increase in fan load caused by large pieces of material clogging the pipe. This not only improves the continuity and stability of the conveying process, but also increases the contact area between the material and the airflow, which is conducive to more uniform and efficient subsequent micro-dehydration. At the same time, it reduces the local blockage of the suction port caused by material caking and reduces the frequency of manual cleaning.

[0042] The circular rod 24 drives the fifth bevel gear 36 to rotate. Since both sixth bevel gears 38 mesh with the fifth bevel gear 36, the rotation of the fifth bevel gear 36 drives the first circular rod 37 to rotate via the sixth bevel gears 38, which in turn drives the two sets of dispersing rods 39 to rotate. Together with the impact rods, these rods break up the adhered materials. Because the impact rods 27 and dispersing rods 39 strike laterally and longitudinally respectively, they form a three-dimensional, intersecting breaking network, providing multi-dimensional intervention to material clumps. The laterally rotating impact rods 27 primarily target and break up larger clumps, while the longitudinally rotating dispersing rods 39 further refine the initially broken material. Through the crisscrossing shearing and impact forces, irregular clumps that are difficult to handle with traditional single-direction impacts are thoroughly decomposed into uniform particles. This results in more complete material dispersion and a more uniform particle size distribution, not only avoiding the risk of pipe blockage caused by large pieces of material but also increasing the contact area between the material and the hot airflow in the subsequent micro-dehydration stage, improving dehydration uniformity and efficiency.

[0043] The rotation of the circular rod 24 drives the cleaning rod 28 to rotate. The rotation of the cleaning rod 28 cleans the inner wall of the circular pipe 3, scraping off the material adhering to the inner wall of the circular pipe 3. This prevents the scale formed by long-term accumulation from affecting the inner diameter of the pipe, thereby maintaining a stable cross-sectional area of ​​the airflow channel. When the cleaning rod 28 rotates at high speed with the circular rod 24, it can not only scrape off the statically adhering material, but also throw the scraped fine particles into the mainstream airflow area through centrifugal force, and transport them along with the conveying airflow. This not only ensures the output environment of the circular pipe 3, but also reduces material waste. Combined with the breaking function of the striking rod 27, it reduces the risk of pipe blockage and extends the continuous operation time.

[0044] The cleaning rod 28, comprising a square shell 281 and a rod body 282, utilizes the elastic force of a spring 283 to compress the rod body 282, ensuring that one side of the outer wall of the rod body 282 remains in contact with the inner wall of the circular tube 3. This prevents the cleaning rod 28 from scratching the tube wall or deforming the rod body 282 due to rigid contact. The damper provides controllable buffer resistance, preventing the spring 283 from bouncing violently during equipment start-up, shutdown, or speed changes, maintaining stable flexible contact between the rod body 282 and the tube wall. This ensures continuous cleaning effectiveness, reduces mechanical wear rate, and even when the cleaning rod 28 wears, the elastic force of the spring 283 still keeps the rod body 282 in contact with the inner wall of the circular tube 3. This eliminates the need for frequent adjustments or replacements during long-term use, reducing maintenance costs. Simultaneously, it ensures that the inner wall of the circular tube 3 remains clean, guaranteeing stable airflow and subsequent micro-dehydration. The rotating shaft 7 drives the second bevel gear 13 to rotate, which in turn drives the third bevel gear 14 to rotate. The third bevel gear 14 then drives the double-segment threaded rod 11 to rotate. Since the double-segment threaded rod 11 is threadedly connected to a pair of threaded blocks 12, the rotation of the double-segment threaded rod 11 causes the pair of threaded blocks 12 to move simultaneously toward the center or to both sides. This causes the threaded blocks 12 to move the expansion shell 502. The forward and reverse rotation of the drive device 6 not only causes the suction nozzle 5 to rotate but also deforms it, increasing the suction range and enabling the suction nozzle 5 to dynamically rotate and sweep during the process. Adjusting the suction port width, when the drive device 6 rotates forward, the double-segment threaded rod 11 drives a pair of threaded blocks 12 to move to both sides, and the expansion shell 502 slides outward along the side wall of the shell 501, increasing the lateral span of the suction port and covering a wider grain pile area; when rotating in reverse, the threaded blocks 12 move towards the center, and the expansion shell 502 retracts and resets, adapting to the suction needs of narrow corners or dense grain piles, so that the suction nozzle 5 can quickly sweep and suck up large areas of grain piles, and can also accurately clean up residues in narrow spaces such as the corners of the carriage, effectively solving the problem of insufficient adaptability of traditional suction nozzles in different operating scenarios.

[0045] When the pair of expansion shells 502 move to both sides, they drive the connecting rod 17 to move. Since the connecting rod 17 and the connecting block 18 are hinged, the connecting rod 17 drives the connecting block 18 to move. As the connecting block 18 slides on the air guide plate 16, it pulls the air guide plate 16, causing the air guide plate 16 to change its angle until the pair of air guide plates 16 form a V-shape. At this time, the pair of air guide plates 16 block the center of the shell 501, causing the air force to move along the air guide plate 16 to both sides. When the expansion shells 502 open, the air force draws in grain from both sides. When the expansion shells 502 retract, the air force... The force draws grain from the center. When the expansion shell 502 is in a half-open state, the air guide plate 16 is tilted at a transition angle, so that the wind force forms a gradient distribution between the center and the sides. This ensures the efficiency of the main grain suction and also provides auxiliary suction for the edge areas, realizing dynamic airflow distribution during the grain suction process. Sometimes the grain is sucked from the center, and sometimes from the sides, making the grain suction more uniform. At the same time, when cleaning narrow areas such as the corners of the truck bed, the tilt angle of the air guide plate 16 can guide the airflow to form a directional vortex, which can suck up the remaining grain in the gaps to the suction port, reducing the amount of manual auxiliary cleaning work.

[0046] The rotating rod 19 rotates, driving a set of vibrating rods 29 to rotate. The vibrating rods 29 drive the vibrating balls 30 to rotate, causing the vibrating balls 30 to strike the circular tube 3, generating vibration. This effectively breaks the adhesion between the material and the inner wall of the circular tube 3. Especially for grain particles with high moisture content or stickiness, it can promote their detachment from the tube wall. This, combined with the scraping action of the cleaning rod 28, forms a synergistic cleaning effect, ensuring that the material is transported evenly under the action of airflow.

[0047] The rotating rod 19 drives a pair of linkage rods 31 to rotate via the second sprocket 32 ​​and the second chain 33. The linkage rods 31 drive the auxiliary rod 34 to rotate, and the auxiliary rod 34 drives the auxiliary ball 35 to rotate. This causes the auxiliary ball 35 to strike the outer wall of the circular tube 3, generating vibration. Together with the vibrating ball 30, this forms three vibration points distributed in a circular array. The vibrating ball 30 and the auxiliary ball 35 impact the circular tube 3 from different angles, ensuring that the circular tube 3 is subjected to uniform force. The vibration waves form superimposed interference within the tube wall, effectively avoiding the vibration dead zones and uneven energy distribution problems that are prone to occur with a single vibration source. This improves the anti-sticking and anti-clogging effect. Furthermore, since the rotating rod 19 and the pair of linkage rods 31 share the same power source, the overall energy consumption is lower than the sum of multiple independent vibrators, resulting in energy-saving effects.
