Description

Technical Field

[0001] The utility model relates to the technical field of seeding devices, in particular to a collecting and rowing drum type seeding body. Background Art

[0002] The collective seeding drum type seeding body has the advantages of fast seeding speed, low missed seeding rate, and good adaptability to different seeding modes. Its working principle is that after the fan blows air, part of the airflow blows the seeds upward from the wind plate, and the other part of the airflow is used to blow the seeds into the seed guide tube. Please refer to the Chinese utility model patent with announcement number CN222827658U applied by our company earlier. However, the current wind force cannot be accurately controlled. If the wind force is too low, the seeding operation cannot be carried out smoothly, so the wind force can only be set higher to ensure the operation. However, after such a setting, when the wind force is relatively strong, the seeds will be blown higher. Under the joint action of the two parts of the airflow, some seeds will be blown to the other side of the seeding drum, but these seeds cannot fall back on the wind plate, resulting in rapid consumption of seeds. It is important to mention here that even if the air volume is set for a certain area of ​​seeds, the seed varieties need to be changed during large-scale planting services, and even seeds of the same variety have different sizes and specifications. Therefore, even if the air volume is adjustable, how to achieve the desired seeding effect still needs to rely on experience and judgment. Therefore, when adjusting the air volume, the air volume has to be appropriately increased, which will cause seed consumption to a certain extent. In addition, the recovery of the seeds that are blown away is also very inconvenient. Currently, the seeding drum needs to be removed before the seeds can be picked up manually, which is very troublesome. In view of this, a targeted improvement plan is proposed. Utility Model Content

[0018] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0019] See Figures 1 to 3 , the present utility model proposes a collective row roller type seed metering body, including a box body 1, a seed box 12 is provided at the top of the box body 1 and an observation port 11 is opened, and a transparent cover plate is provided at the observation port 11. Since it is transparent, the cover plate is not shown in the drawings. The inside of the box body 1 can be observed through the observation port 11.

[0020] Inside the box body 1, there are a seed metering drum 2 and an air duct 14. The observation port 11 is located above the seed metering drum 2. In addition, there is a rotating shaft 3 which is rotatable. The rotating shaft 3 and the air duct 14 are respectively located on both sides of the seed metering drum 2. The rotating shaft 3 is connected to a receiving plate 4. The receiving plate 4 is used to receive the dropped seeds between the seed metering drum 2 and the inner wall of the box body 1, and can place the received seeds below the receiving plate 4 after the rotating shaft 3 rotates. In other words, by rotating the rotating shaft 3, the receiving plate 4 can be rotated to different positions. The receiving plate 4 can block the relative space between the seed metering drum 2 and the inner wall of the seed box 12, just as Figure 3 shown.

[0021] Furthermore, the rotating shaft 3 is connected to a handle 5. The handle 5 is arranged outside the box body 1. The handle 5 is a triangular plate. An arc-shaped limiting groove 51 is arranged on the handle 5. A setscrew 6 connected to the box body 1 is arranged in the limiting groove 51, so that the handle 5 can be fixed by the setscrew 6. The arc angle range of the limiting groove 51 is the same as the rotation angle range of the receiving plate 4. This means that the two ends of the limiting groove 51 limit the extreme positions of the rotation range of the rotating shaft 3, avoiding excessive rotation of the receiving plate 4 and damaging the seed metering drum 2. At the same time, the position of the receiving plate 4 can be quickly and accurately adjusted based on the end positions of the limiting groove 51.

[0022] The specific application process is that in actual operation, due to too large air volume setting, some seeds will be blown to the side of the seed metering drum 2 away from the air duct 14. In this way, the seeds will directly fall on the receiving plate 4. Through the observation of the observation port 11, this situation can be directly observed. Without the receiving plate 4, the seeds will directly fall below the seed metering drum 2, but the operators outside cannot know whether this situation occurs. They can not only not adjust the air volume more accurately, but also after long-term operation, the seeds will accumulate below the seed metering drum 2, causing seed damage and equipment abnormality. In addition, it is possible to adjust the air volume by observing whether there are seeds above the receiving plate 4 and the speed of seed accumulation. After the air volume is adjusted properly, in the normal use state of the collective and row-type seed metering body, the process of seed accumulation on the receiving plate 4 should be slow, and it can be cleaned regularly. When cleaning is required, rotate the rotating shaft 3 to make the seeds on the receiving plate 4 fall. A seed dropping port is arranged below the seed metering drum 2. A baffle 13 is arranged at the seed dropping port. The baffle 13 is fixed by bolts to prevent air leakage. After opening the baffle 13, the seeds can be cleaned out.
