Technical Field

[0001] This utility model relates to a seeder and belongs to the field of agricultural machinery and equipment. Background Technology

[0002] When sowing rice, seeds are usually soaked a few days in advance to ensure they absorb enough water. Moist seeds tend to clump together when left to stand, and during machine sowing, clumps can clog the seeder's outlet, significantly impacting sowing efficiency and quality. Utility Model Content

[0003] The purpose of this invention is to provide a seeder that can limit the size of the seeder inlet by adjusting the sliding of the plate, preventing clumped seeds from entering the seeder through the inlet and ensuring smooth sowing; furthermore, by changing the size of the inlet, the flow rate of seeds entering the seeder can be adjusted, achieving precise adjustment of the sowing flow rate to meet different agronomic needs.

[0004] This utility model is achieved through the following technical solution.

[0005] A seeder includes a seed storage bin for holding seeds, multiple seed conveying pipes connected to the seed storage bins and for conveying seeds, and multiple seeders for sowing seeds that are connected to the seed conveying pipes one-to-one. The seeder includes a rotating chamber and a rotating element, the rotating element being disposed in the rotating chamber. The rotating chamber has an inlet and an outlet. Rotation of the rotating element causes seeds entering the rotating chamber through the inlet to be ejected from the outlet. The conveying pipes are connected to the inlet. An adjusting plate is provided at the inlet and can slide along the extension direction of the inlet. The adjusting plate is slidable to adjust the size of the inlet to regulate the seed flow rate entering the rotating chamber.

[0006] As a further improvement of this utility model, the inlet extends vertically and is located inside the conveying pipe. The conveying pipe is provided with a vertically extending groove above the inlet. The adjusting plate is slidably embedded in the groove and is at least partially located outside the conveying pipe.

[0007] As a further improvement of this utility model, it also includes a drive mechanism for driving multiple adjustment plates to move synchronously; the drive mechanism includes a first driver, a rotating shaft driven by the first driver, and multiple gears mounted on the rotating shaft corresponding one-to-one with the adjustment plates. The adjustment plates are provided with racks that mesh with the corresponding gears, and the racks extend along the sliding direction of the adjustment plates; when the rotating shaft rotates, it drives multiple adjustment plates to move synchronously.

[0008] As a further improvement of this utility model, the portion of the adjusting plate that extends above the conveying pipe is in close contact with the seed storage bin. A positioning part is provided on the side of the adjusting plate facing the seed storage bin. The seed storage bin is provided with a plurality of inwardly recessed positioning grooves that cooperate with the positioning part. The plurality of positioning grooves are closely arranged in the vertical direction. The movement of the adjusting plate causes the positioning part to be embedded in one of the positioning grooves.

[0009] As a further improvement of this utility model, the positioning part is arranged in a hemispherical shape.

[0010] As a further improvement of this utility model, both horizontal ends of the seed storage bin are fixedly connected to mounting plates, the rotating shaft is rotatably positioned on the two mounting plates, and the first driver is mounted on one of the mounting plates.

[0011] As a further improvement of this utility model, it also includes a drive shaft that passes through multiple rotary chambers and is connected to multiple rotary components. The rotary components are fixedly sleeved on the drive shaft, and the rotation of the drive shaft drives the multiple rotary components to rotate synchronously. The drive shaft is driven to rotate by a second driver.

[0012] As a further improvement of this utility model, the bottom of the seed storage bin is provided with multiple seed outlets that correspond one-to-one with the conveying pipe; the seed storage bin has a structure that is wider at the top and narrower at the bottom.

[0013] As a further improvement of this utility model, the inner wall of the conveying pipe located directly below the chute forms a horizontally extending support surface. When the support surface abuts against the lower end face of the adjusting plate, the adjusting plate completely blocks the inlet.

[0014] As a further improvement of this utility model, the inlet is formed on the side of the rotary cavity, and the outlet is formed at the bottom of the rotary cavity.

[0015] The beneficial effects of this utility model are:

[0016] 1. When clumped seeds enter the delivery pipe, the size of the inlet can be limited by the sliding of the adjusting plate to prevent clumped seeds from entering the seeder and ensure smooth sowing.

[0017] 2. By changing the position of the adjusting plate to control the size of the inlet, the number of seeds entering the seeder can be adjusted, thereby achieving precise adjustment of the seeding flow rate to meet different agronomic needs.

[0018] 3. By controlling the first driver, all adjustment plates can be moved synchronously. On the one hand, this avoids errors caused by manually adjusting the flow rate of each seeder one by one, ensuring the consistency of the flow rate of each seeder. On the other hand, compared with adjusting each adjustment plate one by one, efficiency is significantly improved. Attached Figure Description

[0019] The preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings to help understand the purpose and advantages of this utility model, wherein:

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0025] This embodiment provides a seeder, referring to... Figures 1-2 The system includes a seed storage bin 1 for holding seeds, multiple seed conveying pipes 2 connected to the seed storage bins 1 and used for conveying seeds, and multiple seeders 3 connected to the conveying pipes 2 for sowing seeds. The seeder 3 includes a rotating chamber 32 and a rotating element 31. The rotating element 31 is disposed in the rotating chamber 32. The rotating chamber 32 has an inlet 33 and an outlet 34. The rotation of the rotating element 31 will push the seeds that enter the rotating chamber 32 through the inlet 33 out of the outlet 34. The conveying pipe 2 is connected to the inlet 33. Furthermore, an adjusting plate 4 is provided at the inlet 33 that can slide along the extension direction of the inlet 33. The adjusting plate 4 slides to adjust the size of the inlet 33 so as to adjust the seed flow rate entering the rotating chamber 32.

[0026] When clumped seeds enter the interior of the delivery pipe 2, the size of the inlet 33 can be limited by the sliding of the adjusting plate 4, thereby preventing clumped seeds from entering the seeder 3 through the inlet 33 and ensuring smooth sowing.

[0027] Furthermore, by changing the position of the adjusting plate 4 to control the size of the inlet 33, the number of seeds entering the seeder 3 can be adjusted, thereby achieving precise adjustment of the seeding flow rate to meet different agronomic needs.

[0028] The design of the rotating part 31 rotating in the rotating cavity 32 to release seeds quickly from the seeder 3, avoiding seed blockage in the seeder 3.

[0029] In this embodiment, the inlet 33 extends vertically and is located inside the conveying pipe 2. The conveying pipe 2 is provided with a vertically extending groove 21 above the inlet 33. The adjusting plate 4 is slidably embedded in the groove 21, and the adjusting plate 4 is at least partially located outside the conveying pipe 2, so that the operator can directly slide the adjusting plate 4 from the outside for convenient operation.

[0030] Furthermore, the slide 21 extends vertically and the adjusting plate 4 moves vertically, which simplifies the control of the adjusting plate 4 and simplifies the structure.

[0031] In this embodiment, the driving mechanism includes a first driver (not shown in the figure), a rotating shaft 51 driven by the first driver, and multiple gears 52 mounted on the rotating shaft 51 corresponding to the adjustment plates 4. The rotating shaft 51 extends horizontally, and the gears 52 are fixedly sleeved on the rotating shaft 51. When the rotating shaft 51 rotates, it can drive the multiple gears 52 to rotate synchronously. The adjustment plate 4 is provided with a rack 53 that meshes with the corresponding gear 52. The rack 53 extends vertically. When the rotating shaft 51 rotates, the multiple gears 52 rotate synchronously, thereby driving the multiple adjustment plates 4 to move vertically synchronously. Therefore, by controlling the first driver, all adjustment plates 4 can be controlled to move synchronously. On the one hand, this avoids errors caused by manually adjusting the flow rate of each seeder 3 one by one, ensuring the consistency of the flow rate of each seeder 3. On the other hand, compared with adjusting each adjustment plate 4 one by one, it significantly improves efficiency.

[0032] It should be noted that the first driver here can be a servo motor, and the first drive motor and the rotating shaft 51 can be connected by a coupling or a pulley or other transmission components.

[0033] In this embodiment, mounting plates 6 are fixedly connected to the horizontal sides of the seed storage bin 1. The two ends of the rotating shaft 51 are respectively rotatably positioned on the two mounting plates 6. The first driver is installed on one of the mounting plates 6. The rotating shaft 51 can be rotatably connected to the mounting plate 6 through bearings to ensure the stability of the rotating shaft 51 when rotating.

[0034] Furthermore, in some other embodiments, reference is made to Figure 3 When the drive mechanism is not installed, the adjusting plate 4 can also be adjusted manually by pushing and pulling. Specifically, the part of the adjusting plate 4 that protrudes above the conveying pipe 2 is close to the seed storage bin 1. The side of the adjusting plate 4 facing the seed storage bin 1 is provided with a positioning part 41. The seed storage bin 1 is provided with multiple positioning grooves 11 that cooperate with the positioning part 41. The multiple positioning grooves 11 are closely arranged in the vertical direction. The movement of the adjusting plate 4 causes the positioning part 41 to be embedded in one of the positioning grooves 11. Here, the positioning part 41 is hemispherical, and correspondingly, the positioning groove 11 is hemispherical. When the hemispherical positioning part 41 is embedded in the positioning groove 11, the contact area between the two is large, so that the adjusting plate 4 can be positioned on the outer wall of the seed storage bin 1.

[0035] In this embodiment, the inlet 33 is formed on the side of the rotating cavity 32 and the outlet 34 is formed at the bottom of the rotating cavity 32, so that the movement path of the seed in the rotating cavity 32 is shorter, thereby avoiding the seed from being blocked in the rotating cavity 32 and reducing the collision damage of the seed in the rotating cavity 32, thus ensuring the seed quality.

[0036] The seeder 3 in this embodiment also includes a drive shaft 7, which extends horizontally and passes through multiple rotating chambers 32. The drive shaft 7 is connected to multiple rotating components 31, which are fixedly sleeved on the drive shaft 7. The rotating components 31 can be connected to the drive shaft 7 via bushings. Rotation of the drive shaft 7 drives the multiple rotating components 31 to rotate synchronously, while the drive shaft 7 is driven to rotate by a second driver (not shown in the figure). When the second driver operates, it drives the drive shaft 7 to rotate, thereby driving the multiple rotating components 31 to rotate simultaneously, ensuring that the actions of each seeder 3 are consistent and avoiding uneven plant spacing after sowing.

[0037] It should be noted that the two ends of the drive shaft 7 are rotatably positioned on two mounting plates 6 respectively. The drive shaft 7 and the mounting plates 6 can be mounted together via bearings. The second driver is mounted on one of the mounting plates 6. The second driver can also be a servo motor, which is connected to the drive shaft 7 via a coupling or other transmission components.

[0038] In this embodiment, the inner wall of the conveying pipe 2 located directly below the chute 21 forms a horizontally extending support surface. When the support surface abuts against the lower end surface of the adjusting plate 4, the adjusting plate 4 completely blocks the inlet 33. Therefore, seed playback can be stopped or seed leakage can be avoided when turning to prevent seed waste.

[0039] In this embodiment, the bottom of the seed storage bin 1 has multiple seed outlets 12 that correspond one-to-one with the conveying pipe 2. These multiple seed outlets 12 correspond to multiple rows of sowing. One end of the conveying pipe 2 is connected to the seed outlet 12. During sowing, the seeds in the seed storage bin 1 fall into the conveying pipe 2 under gravity. Furthermore, the seed storage bin 1 has a structure that is wider at the top and narrower at the bottom, resulting in a larger volume and the ability to store more seeds, thus reducing the frequency of manual seed replenishment.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
