Description

Technical Field

[0001] This utility model relates to the field of seeder technology, specifically to a horizontal discharge mechanism for a fertilizer box of a seeder and a triangular seeder. Background Technology

[0002] A seed drill is a planting machine that sows crop seeds. Seed drills can accurately deliver seeds and fertilizers to the seedbed according to agronomic requirements. They not only greatly reduce the labor intensity of farmers but also save seeds, seize planting time, and improve sowing quality, providing a reliable guarantee for increased production and income for farmers.

[0003] Delivering fertilizer to the seedbed requires fertilization equipment, which is typically mounted on agricultural machinery such as seeders. This equipment applies fertilizer as the seeder moves along with the planter. In large seedbeds, primarily using raised beds or ridges, the area is relatively large, necessitating horizontal fertilization equipment to facilitate multi-point fertilization and improve efficiency. For example, Chinese patent document CN217363795U discloses a high-efficiency fertilization device for vegetables, including a fertilizer bin with a screw feeder inside and a fertilizer outlet pipe at the bottom. The screw feeder is horizontal and rotatable to prevent fertilizer blockage within the bin; however, this device does not allow adjustment of the fertilizer output. Utility Model Content

[0004] The purpose of this utility model is to provide a horizontal discharge mechanism for the fertilizer box of a seeder and a triangular seeder, which solves the problem that the fertilizer discharge amount cannot be adjusted in the existing technology.

[0005] To achieve the above objectives, this utility model provides a horizontal discharging mechanism for a fertilizer box of a seeder, installed on the fertilizer discharging side of the fertilizer box. It includes a fertilizer discharging box with a fertilizer cavity inside, the fertilizer cavity communicating with the discharge port of the fertilizer box. It also includes a rotating body that passes through the fertilizer discharging box and rotates relative to it, located between the fertilizer inlet and outlet of the fertilizer box. The rotating body includes a first fertilizer discharging area and a second fertilizer discharging area, each with a first fertilizer trough and a second fertilizer trough, the first and second fertilizer troughs having different volumes and both located on the rotation surface of the rotating body. The positions of the first and second fertilizer discharging areas within the fertilizer cavity are adjustable.

[0006] Furthermore, the rotating body is connected to an adjusting device, which causes the rotating body to move linearly relative to the fertilizer outlet box.

[0007] Furthermore, the adjusting device includes an adjusting rod, on which multiple rotating bodies are mounted along the length direction. The adjusting rod and the rotating bodies are coaxially arranged, and the rotating bodies remain fixed relative to the adjusting rod. The fertilizer dispensing box is provided with multiple rotating bodies.

[0008] Furthermore, one end of the adjusting rod is provided with an external thread, and a rotating nut is fitted on the adjusting rod at the position corresponding to the external thread, and the rotating nut is connected to the rotating handle.

[0009] Furthermore, the first fertilizer discharge zone and the second fertilizer discharge zone each occupy half of the space along the length of the rotating body.

[0010] Furthermore, the first fertilizer trough is semi-cylindrical and occupies half of the volume of the first fertilizer outlet area; the second fertilizer trough is a strip-shaped trough and there are multiple second fertilizer troughs, which are dispersed on the surface of the second fertilizer outlet area.

[0011] Furthermore, the adjusting rod is provided with latching components at both ends of the rotating body along its length direction, and the latching components keep the rotating body and the adjusting rod relatively fixed.

[0012] Furthermore, the rotating bodies on both sides of the center in the length direction of the adjusting rod are symmetrically arranged about the center.

[0013] Furthermore, the adjusting rod is provided with a driven member, which is connected to the driving mechanism. The driving mechanism drives the adjusting rod to rotate around its own central axis through the driven member.

[0014] Furthermore, the fertilizer outlet of the fertilizer box is connected to a fertilizer application pipe, which extends towards the ground.

[0015] This utility model also provides a triangular seeder, including the above-mentioned horizontal fertilizer box discharge mechanism.

[0016] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects:

[0017] This invention relates to a horizontal fertilizer discharge mechanism for a seeder. The fertilizer discharge box receives fertilizer from the fertilizer chamber. A rotating body passes through the fertilizer discharge box and is located between the fertilizer inlet and outlet. As fertilizer falls from the fertilizer chamber, it passes over the rotating body, which acts as a buffer, slowing down the fertilizer's descent. During the fertilizer's descent, the rotating body continues to rotate. The rotating body is rotatably positioned relative to the fertilizer discharge box, with a first fertilizer trough and a second fertilizer trough positioned on the rotating surface. The first and second fertilizer troughs have different volumes, resulting in different descent amounts of fertilizer as they pass through them. The amount of fertilizer discharged can be controlled by adjusting the positions of the first and second fertilizer discharge areas within the fertilizer chamber.

[0018] It is obvious that the elements or features described in the above individual embodiments can be used alone or in combination in other embodiments. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on the preferred embodiments, and such other ways also fall within the scope of the present invention.

[0028] Reference Figures 1-5This embodiment provides a horizontal fertilizer discharge mechanism for a seeder, installed on the fertilizer discharge side of the fertilizer box 100, specifically the lower side of the fertilizer box 100. Under gravity, the fertilizer moves downwards and is discharged from the fertilizer box 100. The discharge mechanism includes a fertilizer discharge box 200 and a rotating body 310. The fertilizer discharge box 200 has a fertilizer cavity inside, which communicates with the discharge port of the fertilizer box 100. When the fertilizer is discharged from the fertilizer box 100, it first passes through the fertilizer discharge box 200 and transitions within it. The rotating body 310 passes through the fertilizer discharge box 200 and rotates relative to it. The rotating body 310 is located between the fertilizer inlet and outlet of the fertilizer discharge box 200. As the fertilizer falls from the fertilizer box 100, it passes through the rotating body 310, which acts as a buffer, slowing down the falling speed of the fertilizer. During the fertilizer's descent, the rotating body 310 maintains its rotation to prevent the stationary rotating body 310 from slowing down the fertilizer's descent and causing blockages. The rotating body 310 includes a first fertilizer outlet area 311 and a second fertilizer outlet area 312. The first fertilizer outlet area 311 and the second fertilizer outlet area 312 are respectively provided with a first fertilizer trough 314 and a second fertilizer trough 313. The first fertilizer trough 314 and the second fertilizer trough 313 have different volumes and are both located on the rotation surface of the rotating body 310. Therefore, the amount of fertilizer falling is different when passing through fertilizer troughs of different volumes. The positions of the first fertilizer outlet area 311 and the second fertilizer outlet area 312 within the fertilizer chamber are adjustable. By adjusting the positions of the first fertilizer outlet area 311 and the second fertilizer outlet area 312, the amount of fertilizer dispensed can be controlled.

[0029] Furthermore, adjusting the positions of the first fertilizer dispensing zone 311 and the second fertilizer dispensing zone 312 requires displacing the rotating body 310 relative to the fertilizer dispensing box 200, so that the fertilizer falls through different fertilizer troughs, thereby adjusting the fertilizer dispensing rate. For example... Figure 2 and Figure 3 As shown, in some embodiments, the rotating body 310 is connected to the adjusting device 300, which causes the rotating body 310 to move linearly relative to the fertilizer dispensing box 200. Specifically, the adjusting device 300 includes an adjusting rod 320, on which multiple rotating bodies 310 are mounted along its length. The adjusting rod 320 and the rotating bodies 310 are coaxially arranged, and the rotating bodies 310 remain fixed relative to the adjusting rod 320. When the adjusting rod 320 rotates, it can simultaneously drive multiple rotating bodies 310 to rotate. It is understood that there are many ways to keep the rotating bodies 310 relatively fixed relative to the adjusting rod 320. They can be fixedly connected together, such as by adhesive bonding or bolt fixing, or other methods can be used. The fertilizer dispensing box 200 has multiple rotating bodies 310. Having multiple fertilizer dispensing boxes 200 and rotating bodies 310 can improve fertilization efficiency, enabling fertilization of a larger area of ​​land within a unit of time.

[0030] It is understandable that to achieve the linear motion of the rotating body 310, thereby changing the positions of the first fertilizer discharge area 311 and the second fertilizer discharge area 312, a linear motion mechanism is required. There are many structural forms of linear motion mechanisms, such as threaded drive structures, eccentric wheel structures, linear guide and lead screw combination structures, and cylinder or hydraulic cylinder driven structures. For structural simplicity and reliable transmission, in some embodiments, such as... Figure 2 As shown, one end of the adjusting rod 320 is provided with an external thread, and a rotating nut 330 is fitted to the adjusting rod 320 at the corresponding position of the external thread. The adjusting rod 320 passes through the rotating bearing 390 and is connected to the rotating nut 3301. The rotating nut 330 is connected to the rotating handle 340. When the rotating nut 330 is rotated by rotating the handle 340, the adjusting rod 320 will move axially (i.e., along its length) under the action of the thread, thereby driving the rotating body 310 to move and adjusting the position of the first fertilizer outlet zone 311 and the second fertilizer outlet zone 312 within the fertilizer chamber.

[0031] Furthermore, to prevent the adjusting rod 320 from undergoing axial linear motion during rotation, which could cause the rotating body 310 to shift position, after the rotating body 310 is adjusted, a limiting structure is used to hold the rotating nut 330 in place, preventing the rotating nut 330 from rotating. This prevents the adjusting rod 320 from undergoing axial linear motion and thus avoids the rotating body 310 from shifting. It should be noted that the limiting structure here uses a wing nut 370 and a locking nut 380. The rotating bearing 390 is positioned between the rotating nut 330 and the wing nut 370, the locking nut 380 is positioned outside the rotating handle 340, and the wing nut 370 is positioned inside the rotating bearing 390. In other words, the rotating handle 340 and the wing nut 370 are located on either side of the rotating nut 330. Before the fertilizer shaft 240 rotates, the adjusting handle 252, together with the rotating nut 251, is pressed against the outside of the rotating bearing 255 by rotating the locking nut 254, and the inside of the rotating bearing 255 is locked by the wing nut 253, so that the axial direction of the fertilizer shaft 240 can be kept fixed.

[0032] In some embodiments, the first fertilizer outlet area 311 and the second fertilizer outlet area 312 each occupy half of the space along the length direction of the rotating body 310. The first fertilizer outlet area 311 and the second fertilizer outlet area 312 are evenly proportioned, and when the rotating body 310 moves axially, the proportion of the first fertilizer outlet area 311 and the second fertilizer outlet area 312 within the fertilizer chamber of the fertilizer outlet box 200 can change with the movement of the rotating body 310. Further, as... Figure 3 , Figure 4 and Figure 5As shown, the first fertilizer trough 314 is semi-cylindrical and occupies half the volume of the first fertilizer outlet area 311. The first fertilizer trough 314 has a relatively large volume and can hold more fertilizer. Multiple second fertilizer troughs 313 are strip-shaped and are distributed on the surface of the second fertilizer outlet area 312. The volume of a single second fertilizer trough 313, or even the sum of the volumes of multiple second fertilizer troughs 313, is no greater than the volume of the first fertilizer trough 314. In this embodiment, three second fertilizer troughs 313 (i.e., strip-shaped troughs) are provided, and the length direction of the strip-shaped troughs is consistent with the length direction of the rotating body 310.

[0033] In some embodiments, in order to allow individual adjustment of the position of a single rotating body 310 relative to the fat box 200 without changing the positions of other rotating bodies 310, such as Figure 3 As shown, locking components 350 are provided at both ends of the adjusting rod 320 corresponding to the length direction of the rotating body 310. The locking components 350 keep the rotating body 310 and the adjusting rod 320 relatively fixed. At this time, the rotating body 310 is movably sleeved on the adjusting rod 320, and the locking components 350 cooperate with the adjusting rod 320. The two sets of locking components 350 are respectively engaged with the adjusting rods 320 at both ends of the rotating body 310. When the position of the rotating body 310 needs to be adjusted, the locking components 350 at both ends can be released to move the rotating body 310. Furthermore, the rotating bodies 310 on both sides of the center of the adjusting rod 320 are symmetrically arranged about this center. This symmetrical arrangement ensures that the initial positions of the fertilizer troughs before rotation of the rotating bodies 310 on both sides are different, facilitating corresponding triangular fertilization when the seeder performs triangular sowing. Figure 2 As shown, four rotating bodies 310 are provided on the adjusting rod 320, and the first fertilizer outlet area 311 of the two rotating bodies 310 on the same side are both set towards the center of the adjusting rod 320.

[0034] Understandably, the adjusting rod 320 needs to be driven by power to rotate. In some embodiments, the adjusting rod 320 is provided with a driven member 360, which is connected to a drive mechanism. The drive mechanism drives the adjusting rod 320 to rotate around its central axis through the driven member 360. Specifically, the driven member 360 is a driven gear or pulley, fixedly sleeved on the outside of the adjusting rod 320, and connected to the drive mechanism through a chain or transmission belt. The drive mechanism can be a motor, and the rotation of the motor causes the driven gear or pulley to rotate, driving the adjusting rod 320 to rotate around its central axis. It should be noted that the fertilizer outlet of the fertilizer box 200 is connected to a fertilizer application pipe 400, which extends towards the ground. The fertilizer application pipe 400 can be a straight pipe or a curved pipe, and its outlet leads to the ground, allowing the fertilizer to fall onto the ground.

[0035] Another aspect of this application provides a triangular seeder, including the aforementioned horizontal fertilizer box discharge mechanism, which can adjust the amount of fertilizer applied while the seeder is working.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Thanks to the teachings of this utility model, those skilled in the art will readily recognize that alternative structures to the disclosed structure can be used as feasible alternative implementations, and that the disclosed implementations can be combined to produce new implementations, which also fall within the scope of the appended claims.
