Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically, it relates to an anti-blocking seeding structure and its agricultural seeder. Background Technology

[0002] The core component of a seeder is the seed metering wheel, which is usually designed with seed metering chambers. During the rotation of the seed metering wheel, the seed metering chambers first rotate to the top to receive seeds from the hopper, and then rotate to the bottom to allow the seeds to fall and be sown.

[0003] A document with publication number (CN222366619U) discloses an anti-clogging seed metering wheel for a seeder, which includes: a wheel axle, a seed metering ring, and impact columns. The seed metering ring is concentrically arranged on the wheel axle, and an annular cavity is left between the inner wall of the seed metering ring and the outer circle of the wheel axle. Seed storage holes are arranged at intervals on the seed metering ring. The impact columns are arranged in the annular cavity and correspond one-to-one with the seed storage holes. The front end of the impact column extends into the corresponding seed storage hole, and the tail end of the impact column is provided with a limit plate.

[0004] The seeder of the above device uses an anti-clogging seed metering wheel that reciprocates in the seed storage hole along with the rotation of the seed metering ring via an impact column. The impact force when the impact column falls actively pushes the seeds out of the seed storage hole, thus avoiding the problem of seeds getting stuck and blocked in the seed storage hole.

[0005] The aforementioned device uses the impact column to knock the seeds out of the seed metering ring under the action of gravity, but the impact force generated by the rotating seed metering ring is limited, and it does not effectively solve the problem of seed blockage.

[0006] In view of this, this utility model is hereby proposed. Utility Model Content

[0007] To solve the problem of seed clogging, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A seed-discharging anti-clogging structure includes seed-discharging tubes, with multiple seed-discharging tubes for seed discharging; and an anti-clogging component, which is disposed on one side of a corresponding seed-discharging tube and is used to prevent seeds from clogging inside the seed-discharging tube. The anti-clogging component includes a mounting frame, a drive wheel, a drive shaft, and a swing block. The drive wheel is rotatably connected to the middle of the mounting frame, and the drive wheel is drivenly connected to the drive shaft. The swing block is drivenly connected to the drive wheel, and both sides of the swing block are respectively inserted into the seed-discharging tubes.

[0009] In a preferred embodiment of this utility model, a movable frame is rotatably connected to the mounting frame, and a fixed column is fixedly connected to one end of the movable frame that is rotatably connected to the mounting frame.

[0012] In a preferred embodiment of this utility model, each of the fixed blocks is rotatably connected to a baffle at its end, and each baffle is slidably connected to the seeding pipe, with a distance between the two baffles.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] Please see Figure 1-5A seed-discharging structure for preventing clogging includes seed-discharging tubes 3, with multiple seed-discharging tubes 3 for seed discharging; and an anti-clogging component, which is disposed on one side of a corresponding seed-discharging tube 3 to prevent seeds from clogging inside the seed-discharging tube 3. The anti-clogging component includes a mounting frame 2, a transmission wheel 21, a transmission shaft 4, and a swing block 5. The transmission wheel 21 is rotatably connected to the middle of the mounting frame 2, and the transmission wheel 21 is driven by the transmission shaft 4. The swing block 5 is driven by the transmission wheel 21, and its two sides are inserted into the seed-discharging tubes 3 respectively. The transmission shaft 4 drives the components inside the anti-clogging component to work together. The transmission shaft 4 drives the transmission wheel 21 to rotate, and the transmission wheel 21 drives the swing block 5 to swing. During the swing, the swing block 5 intermittently closes the middle of the seed-discharging tube 3, and the seeds in the seed-discharging tube 3 are intermittently discharged through intermittent direct discharge, avoiding the problem of seeds getting stuck and clogging due to friction between the seed-discharging ring and the inner wall during rotation, as is the case with traditional seed-discharging rings.

[0030] The mounting frame 2 is rotatably connected to a movable frame 24. One end of the movable frame 24, which is rotatably connected to the mounting frame 2, is fixedly connected to a fixed column 25. A transmission block 22 is rotatably connected to the periphery of the transmission wheel 21. A support rod 23 is fixedly connected to the other end of the movable frame 24. The transmission block 22 and the support rod 23 are slidably connected. When the transmission wheel 21 rotates, it drives the transmission block 22. The transmission block 22 rotates and slides with the support rod 23, causing the support rod 23 to swing. The swing of the support rod 23 drives the movable frame 24. The movable frame 24 drives the fixed column 25 to rotate back and forth. Through the back and forth swing, the seeding tube 3 is intermittently seeded.

[0031] The fixed column 25 has a swing block 5 fixedly connected to its middle part. The swing block 5 is Y-shaped and has a bracket extending from the other end. Both ends of the swing block 5 are fixedly connected to fixed blocks 51. Each fixed block 51 has a baffle 52 rotatably connected to its end. Each baffle 52 is slidably connected to the seed metering tube 3. There is a distance between the two baffles 52. The fixed column 25 swings back and forth, driving the swing block 5. The swing block 5 drives the fixed block 51 to move along with it. The fixed block 51 moves, driving the baffle 52 to move. The baffle 52 is slidably connected to the seed metering tube 3. During the movement of the baffle 52, because the baffle 52 is rotatably connected to the fixed block 51, the movement of the baffle 52 is not interfered with by the movement of the fixed block 51. The baffle 52 intermittently closes the middle part of the seed metering tube 3 during the reciprocating movement. The seeds in the seed metering tube 3 are intermittently discharged through the intermittent direct discharge, avoiding the problem of seeds getting stuck and blocked by friction between the seed metering ring and the inner wall during rotation.

[0032] like Figure 5As shown, a connecting rod is provided between each fixed block 51 and baffle 52. The two ends of the connecting rod are rotatably connected to the corresponding fixed block 51 and baffle 52, and the rotatable connection positions of the two ends of the connecting rod are staggered. When the fixed block 51 rotates, it drives one end of the connecting rod, and the other end of the connecting rod drives the baffle 52 to move. Because the baffle 52 slides with the seeding pipe 3, under the arc-shaped movement tendency of the fixed block 51, and with the intervention of the movement of the connecting rod and the seeding pipe 3, the baffle 52 moves horizontally.

[0033] It is worth noting that the swing amplitude of the fixed column 25 is affected by the size of the transmission wheel 21. The smaller the size of the transmission wheel 21, the smaller the swing amplitude of the fixed column 25; the larger the size of the transmission wheel 21, the larger the swing amplitude of the fixed column 25. In this device, the transmission wheel 21 can be replaced. The swing amplitude of the swing block 5 is affected by the swing amplitude of the fixed column 25. The moving distance of the baffle 52 is affected by the swing amplitude of the swing block 5, so as to control the amount of seeds emitted.

[0034] The transmission shaft 4 is fixedly connected to a first bevel gear 41, which meshes with a second bevel gear 42. A transmission belt 44 is provided between the second bevel gear 42 and the transmission wheel 21. The two ends of the transmission belt 44 are respectively connected to the transmission wheel 21 and the end of the second bevel gear 42. The transmission shaft 4 is driven by the moving wheel on the main body 1 of the agricultural seeder. When the transmission shaft 4 rotates, it drives the first bevel gear 41. The first bevel gear 41 meshes with the second bevel gear 42. The second bevel gear 42 drives the transmission belt 44, which drives the transmission wheel 21. The rotation of the moving wheel drives the components inside the anti-blocking assembly, and the operation of the machine drives the internal components.

[0035] An agricultural seeder includes a main body 1, with a seed storage box 11 fixedly connected to the upper end of the main body 1, a seed discharging pipe 3 fixedly connected to the seed storage box 11, a mounting frame 2 fixedly connected to the top of the main body 1, and the bottom of the main body 1 equipped with all the aforementioned anti-clogging seed discharging structures. A movable wheel is mounted on the bottom of the main body 1, and a drive shaft 4 is fixedly connected to the middle of one end of the movable wheel. A mounting rod 43 is fixedly connected to the bottom of the main body 1, and a second bevel gear 42 is rotatably connected to the mounting rod 43. The drive shaft 4 drives the components within the anti-clogging assembly to work together. The drive shaft 4 drives the drive wheel 21 to rotate through the components, and the drive wheel 21 drives the swing block 5 to swing. The swing block 5 intermittently closes the middle of the seed discharging pipe 3 during swinging, intermittently discharging the seeds from the seed discharging pipe 3. This intermittent direct discharge avoids the problem of seeds getting stuck and blocked by friction between the traditional seed discharging ring and the inner wall during rotation.

[0036] Working principle: The transmission shaft 4 drives the components within the anti-clogging assembly to work together. The transmission shaft 4 drives the transmission wheel 21 to rotate, and the transmission wheel 21 drives the swing block 5 to swing via the transmission belt 44. During the swing, the swing block 5 intermittently closes the middle of the seed metering tube 3, intermittently discharging the seeds in the seed metering tube 3. This intermittent direct discharge avoids the problem of seeds getting stuck and blocked by friction between the traditional seed metering ring and the inner wall during rotation. The rotation of the transmission wheel 21 drives the transmission block 22, which slides against the support rod 23 and causes the support rod 23 to swing. The oscillating motion of the 23rd element drives the movable frame 24, which in turn drives the fixed column 25 to rotate reciprocally. This reciprocating motion intermittently dispenses seeds into the seed metering tube 3. The reciprocating motion of the fixed column 25 drives the oscillating block 5, which in turn drives the fixed block 51 to move. As the fixed block 51 moves, it drives the baffle 52 to move. The baffle 52 is slidably connected to the seed metering tube 3. During the movement of the baffle 52, because of the rotational connection between the baffle 52 and the fixed block 51, the movement of the baffle 52 is not interfered with by the movement of the fixed block 51. The reciprocating motion of the baffle 52 intermittently closes the middle section of the seed metering tube 3. The seeds in the seed metering tube 3 are intermittently discharged through intermittent closure. This intermittent direct discharge avoids the problem of seed jamming caused by friction between the seed metering ring and the inner wall during rotation, a common issue in traditional seed metering systems. The swing amplitude of the fixed column 25 is affected by the size of the transmission wheel 21; a smaller transmission wheel 21 results in a smaller swing amplitude, and a larger transmission wheel 21 results in a larger swing amplitude. In this device, the transmission wheel 21 is replaceable. The swing amplitude of the swing block 5 is affected by the swing amplitude of the fixed column 25, and the moving distance of the baffle 52 is also affected by the swing amplitude of the swing block 5. The amount of seeds discharged is controlled by the drive shaft 4, which is driven by the moving wheel on the main body 1 of the agricultural seeder. The drive shaft 4 drives the first bevel gear 41 during rotation. The first bevel gear 41 meshes with the second bevel gear 42. The second bevel gear 42 drives the transmission belt 44, which drives the transmission wheel 21. The rotation of the moving wheel drives the components inside the anti-clogging assembly. The operation of the machine drives the internal components. This optimization scheme is mainly for round or curved seeds. Of course, this optimization scheme is not only for round or curved seeds. Seeds of other shapes can still be sown.
