[0027] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0028] In order to deeply understand the distributor device suitable for air-assisted seed metering device provided by the utility model, the application background thereof is discussed first. As the core component of the air-assisted seed metering device, the distributor plays a decisive role in seed metering quality and seeding uniformity. At present, seeding devices are mainly divided into mechanical type and pneumatic type. Although the traditional mechanical precision seeding device such as the hill-drop seed metering device is widely used, its seeding precision is limited, and the seed is easily damaged under high-speed operation. In comparison, the air-assisted seed metering device has become the mainstream direction of the development of seeding technology at home and abroad due to its characteristics of adapting to various crop seed types and high speed and high efficiency.

[0029] However, the existing air-assisted seed metering device still has deficiencies in seed uniform distribution. The uniform distribution quality of the existing air-assisted seed metering device is easily affected by external factors such as vibration and inclination, and it is difficult to meet the high standard requirements of precision seed metering. In addition, once the number and diameter of the seed outlet of the distributor are determined, they cannot be changed, which not only limits the optimization of the internal air flow structure and seed distribution effect, but also makes the seeding method lack flexibility, especially in complex terrain environment, the adaptability is insufficient, and the operation is uneven and not seeded. At the same time, the existing air-assisted seed metering device often faces the problem of seed outlet blockage after the seed is transported into the distributor, which causes the seed to be unable to be discharged smoothly, and further affects the normal operation of the machine.

[0030] Therefore, how to ensure the uniform distribution quality of the seed of each seed outlet of the seed metering device, improve its applicability and reduce the failure rate has become a key problem to be solved in the current seeding technology field.

[0031] Based on the above problems, the utility model provides a distributor device suitable for air-assisted seed metering device, which has uniform distribution of seed quantity of different seed outlets, and the number of seed outlets can be changed according to requirements. At the same time, it has the advantages of automatically removing seed blockage.

[0032] The application relates to a seed distribution device for an air-assisted seed metering device. Figures 1-3 The application relates to a seed distribution device for an air-assisted seed metering device.

[0033] Referring to Figure 1 The application relates to a seed distribution device for an air-assisted seed metering device. The application relates to a seed distribution device for an air-assisted seed metering device.

[0034] In actual application scenarios, the seed tube 10 plays an important role as a channel for seed transmission to the ring-shaped seed planting device 2. With the pushing action of the airflow, the seeds can smoothly pass through the seed tube 10 and finally be accurately discharged from the seed outlet 20 of the ring-shaped seed planting device 2. To ensure the accuracy and efficiency of seed discharge, the system integrates precise sensing and driving technology. Specifically, the sensor 11 is responsible for real-time monitoring of the flow conditions of the seeds inside the seed tube 10. Once it detects that seeds are flowing, the sensor 11 will immediately send a signal to the system controller. As the command center of the entire system, the controller will quickly convey instructions to the rotary drive 3 after receiving this signal, driving the outlet end of the seed tube 10 to make precise angle adjustments. It is worth noting that these preset rotation angles are precisely matched with the angles between adjacent seed outlets 20 on the ring-shaped seed planting device 2. This means that after each rotation of the seed tube 10, its outlet end will be accurately aligned with the next seed outlet 20, ensuring that each seed can be accurately placed in the predetermined position. This process is automatically repeated every time a seed is detected, achieving orderly and accurate seed discharge. By flexibly adjusting the rotation angle of the seed tube 10, the system not only ensures that the seed quantity of each seed outlet remains highly consistent, meeting the strict requirements of precision seed planting, but also easily matches with different numbers of seed outlets according to actual needs. This design greatly improves the applicability and flexibility of the system, providing strong technical support for modern precision seeding operations.

[0035] In one specific example of the present application, as shown in Figure 2 For a clear display, the ring-shaped seed planting device 2 is composed of a circular ring-shaped body 21, which has multiple seed outlets 20 evenly arranged on its side. The seed tube 10 is carefully installed in the internal annular space of the body 21. The design of the seed tube 10 is very ingenious, consisting of a straight tube section and a bent tube section: the straight tube section is coaxial with the body 21, with its axis being the rotation center line of the seed tube 10; the bent tube section is connected to the straight tube section at one end and extends to the seed outlet 20 along the radial direction of the body 21 at the other end. The inlet of the seed tube 10 is located at the end of the straight tube section away from the bent tube section, while the outlet is located at the end of the bent tube section connected to the seed outlet 20. Through the rotation of the straight tube section, the seed tube 10 can drive the bent tube section to rotate together, so that the outlet of the seed tube 10 can be aligned with each seed outlet 20 in turn, achieving accurate seed placement. This design not only ensures that the seed quantity of each seed outlet 20 remains consistent, but also allows the system to flexibly adjust the number of seed outlets according to demand. In order to ensure the stability and smoothness of the seed tube 10 during rotation, the present application also takes an innovative measure. As shown in Figure 3As shown, a ring-shaped limiting groove 22 is arranged in the inner annular space of the body 21, which is accurately arranged along the rotation track of the elbow pipe section. The one end of the seed tube 10 provided with the outlet is ingeniously embedded in this limiting groove and can freely slide therein. In this way, in the process of rotation of the seed tube 10, the limiting groove 22 not only provides stable support for it, but also ensures the accuracy and fluency of its rotation.

[0036] In this specific embodiment of the utility model, in order to adapt to diversified process requirements, the construction mode of the limiting groove has multiple choices. In this example, we specially design a ring-shaped limiting circular platform on the inner side of the ring of the body 21, which is closely embedded with the outlet end of the seed tube 10, thereby ensuring the accurate butt joint between the seed outlet and the seed outlet.

[0037] In actual application, when the sensor 11 detects that the seed passes through the seed tube 10, it will immediately send a signal to the controller. The controller then issues an instruction to the rotary drive 3, driving the straight pipe section of the seed tube 10 to rotate accurately around its axis. This action in turn drives the elbow pipe section to rotate, so that the outlet of the seed tube 10 can be accurately butt jointed with each seed outlet 20 in turn. Such a design not only ensures that the seed amount of each seed outlet remains consistent, meeting the high requirements of precision seed metering, but also through flexible adjustment of the rotation angle of the seed tube 10, flexible matching of different seed outlet numbers can be realized, thereby accurately controlling the outlet number of seeds, greatly improving the applicability of the system.

[0038] The type and installation position of the sensor 11 can be flexibly adjusted according to the actual application scene. For example, infrared sensors or photoelectric sensors can be selected and installed on the straight pipe section or elbow pipe section of the seed tube 10 as long as they can effectively detect whether the seed passes through the seed tube 10. The utility model does not make specific limitations on this to adapt to diversified application requirements.

[0039] Similarly, the type of rotary drive 3 can also be selected according to actual needs. It can be a rotary drive element such as a motor, a hydraulic motor, or a combination of these elements with gear, worm and gear, etc. In this embodiment, we choose a stepper motor as the rotary drive 3, and its output shaft is in transmission connection with the straight pipe section of the seed tube 10.

[0040] In actual work process, when the sensor 11 detects that the seed passes through the seed tube 10, the controller will quickly issue a control instruction to the stepper motor to drive the seed tube 10 to rotate accurately. This operation not only ensures the consistency of the seed amount of each seed outlet, but also realizes the accurate control of the outlet number of seeds.

[0041] At the same time, in order to ensure the orderly discharge of seeds, the system is also equipped with a blocking device. The sensor of the device can monitor whether the seed discharge port is blocked in real time, and feed back the detection signal to the controller in time. Once the blocking condition is detected, the controller will start the unblocking fan immediately to quickly remove the blocking material, so as to ensure the smooth discharge of seeds. This design further improves the stability and applicability of the system.

[0042] It is worth noting that the features in each embodiment of the present application can be combined with each other without conflict to meet more complex and diversified application requirements. Next, we will describe the seeding system corresponding to the above-mentioned distributor device adapted to the air-assisted seed metering device in detail.

[0043] A distributor device adapted to the air-assisted seed metering device, comprising the above-mentioned various devices.

[0044] The new point of the present application is that the seed discharge pipe 10 serves as a channel for the seed to the ring channel seed discharge device 2, ensuring that the seed flows smoothly under the push of the air flow and is discharged through the specific seed discharge port 20. In order to monitor the flow of seeds, the system is equipped with a sensor 11 which can detect whether seeds pass through the seed discharge pipe 10 in real time and transmit this information to the controller in the form of a signal. Once the controller receives the seed passing signal from the sensor 11, it will immediately send an instruction to the rotary drive 3. The rotary drive 3 accurately drives the seed discharge pipe 10 to rotate according to the instruction of the controller. This rotation is based on a series of preset angles, which are not only evenly distributed, but also in a multiple relationship with a reference angle set in the controller, thereby ensuring the accuracy and controllability of the rotation.

[0045] The seed discharge pipe 10 is carefully designed to cooperate with the multiple seed discharge ports 20 evenly distributed on the ring channel seed discharge device 2. By controlling the rotation angle of the seed discharge pipe 10 each time, it can be ensured that it is accurately aligned with different seed discharge ports 20, thereby realizing the one-by-one and orderly delivery of seeds. This accurate delivery process is automatically repeated every time the sensor 11 detects the passage of the next seed.

[0046] In order to ensure the smooth progress of seeding, the system also integrates an intelligent unblocking function. On the opposite side of the seed discharge pipe 10, the sensor 41 is responsible for monitoring the blocking condition of each seed discharge port 21 in real time. Once the sensor 41 detects that a certain seed discharge port is blocked, it will immediately send a signal to the unblocking controller 42. After receiving the signal, the unblocking controller 42 will quickly start the unblocking fan 40 to remove the blocking material through strong air flow, thereby ensuring the smoothness of the seed discharge port 21.

[0047] The design not only ensures that the seed discharge amount of each seed outlet 21 is consistent, meets the high requirement of precision seed discharge, but also can easily realize the matching with different number of seed outlets by flexibly adjusting the rotation angle of the seed shooting pipe 10, greatly improves the applicability and flexibility of the system.

[0048] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
