Description

Technical Field

[0001] The utility model relates to the field of rice planting, in particular to a sowing device for rice planting. Background Art

[0002] Broadcast rice planting is a method of spreading rice seeds evenly across the field. This method is commonly used for sowing seeds of crops, including rice, to ensure that the seeds are evenly distributed in the soil, thereby promoting uniform growth.

[0003] At present, in most small and medium-sized farmlands, in order to save sowing costs, storage barrels and hoppers are usually used to sow rice seeds. During the sowing process, the hopper needs to be repeatedly used to load and unload the seeds, and then evenly spread them in the fields. Generally, this operation method often requires the cooperation of multiple people to complete. The frequent use of the hopper to load and unload seeds will increase labor intensity and may also cause accumulated fatigue of the operators, reducing work efficiency. In addition, it is difficult to ensure the uniformity of seed distribution by relying on manual sowing of seeds, which may lead to intensified competition between rice plants and affect the final yield.

Rollers 2 are symmetrically and rotatably provided on both sides of the base plate 1 so that the device can move on the field. A discharge frame 3 is provided on the top of the base plate 1 for storing seeds to be sown. A connecting frame 4 is provided on the top of the discharge frame 3. The connecting frame 4 is tilted as a whole to facilitate the flow of seeds. A loading frame 5 is provided on the top of the connecting frame 4 to store a large amount of seeds. A spacer rack 6 is provided on the upper inner part of the loading frame 5. The spacer rack 6 is provided with several equally spaced partition rods to prevent seed accumulation and evenly distribute seeds. A quantitative unloading group is provided on the connecting frame 4, and a feeding group is provided on the discharge frame 3.

[0024] like Figure 1-Figure 2 As shown, the quantitative feeding group includes a sliding plate 7, a connecting rod 8, a mounting frame 9 and a screw 10. Sliding plates 7 are slidingly provided on both sides of the upper inner part of the connecting frame 4 to control the seed flow rate and realize quantitative seeding. The ends of the sliding plates 7 on both sides are in contact with each other, and connecting rods 8 are rotatably provided in the middle of the sliding plates 7 on both sides. A mounting frame 9 is provided on the outer side of the middle of the connecting frame 4, and the lower parts of the connecting rods 8 on both sides are rotatably connected to the middle of the mounting frame 9. A screw 10 is provided on one side of the outside of the connecting frame 4. The position of the sliding plate 7 is adjusted by rotation, and one side of the mounting frame 9 is threadedly connected to the screw 10.

[0025] like Figures 1-4As shown, the feeding group includes a dual-axis motor 11, a connecting tube 12, a rotating plate 13, a channel tube 14 and an air pump 15. The dual-axis motor 11 is provided on the left side of the discharging frame 3 to drive the connecting tube 12 to rotate. A connecting tube 12 is provided in the middle of the discharging frame 3 for rotation. A number of evenly distributed air outlets are provided on the connecting tube 12. The connecting tube 12 is connected to the output shaft on one side of the dual-axis motor 11. A rotating plate 13 is symmetrically provided on the outside of the connecting rod. The rotating plate 13 is in rotational contact with the inner wall of the discharging frame 3. A channel tube 14 is provided in the middle of the discharging frame 3. The front side of the channel tube 14 is open. The open mouth of the channel tube 14 allows air to be discharged from the air outlet of the connecting tube 12. The channel tube 14 is located on the inner side of the connecting tube 12. An air pump 15 is provided on the right side of the discharging frame 3 to generate airflow to blow the seeds into the discharging frame 3. The air pump 15 is connected to the channel tube 14.

[0026] like Figure 1 、 Figure 2 and Figure 4 As shown, it also includes a pulley 16, a synchronous belt 17 and a rotating frame 18. A pulley 16 is provided on the other side of the dual-axis motor 11 and the left side of the loading frame 5. A synchronous belt 17 is rotated between the two pulleys 16. A rotating frame 18 is provided at the lower part of the loading frame 5. The left end of the rotating frame 18 is connected to the outer pulley 16. The pulley 16 and the synchronous belt 17 are linked to drive the rotating frame 18 to rotate, which helps to evenly distribute the seeds in the loading frame 5.

[0027] During use, the operator first pours the rice seeds into the loading frame 5. The spacer rack 6 in the loading frame 5 disperses the seeds through the equidistant separation rods arranged thereon to prevent the seeds from piling up and ensure that the seeds can smoothly enter the next-level mechanism. In the startup phase, when the device starts working, the roller 2 follows the push rod to make the device move stably under different terrains. When the device moves, the seeds pass through the spacer rack 6 and enter the quantitative feeding group in the connecting frame 4. The sliding plate 7 in the quantitative feeding group adjusts its position under the drive of the screw 10. By changing the position of the sliding plate 7, the flow rate of the seeds is controlled to achieve accurate quantitative sowing. This process enables the number of seeds falling each time to be controlled, ensuring the uniformity of sowing. After passing the quantitative feeding group, the seeds fall into the discharge frame 3. At this time, the dual-axis motor 11 starts to drive the connecting pipe 12 to rotate. There is a passage in the connecting pipe 12 The airflow generated by the channel pipe 14 and the air pump 15 enters the connecting pipe 12 through the channel pipe 14 and is discharged from the air outlet holes evenly distributed on the connecting pipe 12. The seeds are blown to the discharge frame 3 under the action of the airflow and evenly sown in the field. The open mouth design on the front side of the channel pipe 14 ensures that the airflow can effectively deliver the seeds to the field. The dual-axis motor 11 also drives the rotating frame 18 in the feeding frame 5 to rotate through the linkage of the pulley 16 and the synchronous belt 17. The rotating frame 18 helps to evenly distribute the seeds in the feeding frame 5, ensuring that the seeds can smoothly flow into the quantitative feeding group, further improving the smoothness and uniformity of the sowing process. At the end stage, as the sowing work progresses, the operator can adjust the screw 10 according to the actual situation to adapt to different sowing density requirements. The entire sowing process is completed during the continuous movement of the device, realizing efficient and uniform sowing operations.
