Description

Technical Field

[0001] This utility model relates to the field of rice planting technology, specifically a rice transplanter with dual positioning capability. Background Technology

[0002] Rice is one of the most important food crops for humankind, with a long history of cultivation and consumption. Rice cultivation is a complex agricultural production process involving multiple stages, including breeding and sowing, land preparation and transplanting, field management, harvesting and processing. In the process of rice cultivation, rice transplanters are needed to transplant rice seedlings into suitable soil.

[0003] A rice transplanter is an agricultural machine used to plant rice seedlings into paddy fields. Its main function is to use mechanical claws to remove rice seedlings from the seedbed and plant them into the soil in the field. The main components of a rice transplanter include the frame, transplanting assembly, and transmission system. The quality of rice transplanting is closely related to the efficiency of the rice transplanter.

[0004] In the process of realizing this utility model, the following problems were found in the existing technology: 1. Most of the transplanting components in common rice transplanters are fixed structures. During transplanting, the spacing between seedlings is mostly fixed, and it is not possible to accurately position the spacing between seedlings according to the soil conditions. This results in an excessive number of seedlings in the soil, causing insufficient nutrition for the seedlings, which in turn affects the rice planting effect; 2. When transplanting seedlings, the transplanting depth needs to be adjusted according to different soil conditions. However, common rice transplanters are often not convenient for depth positioning, which reduces the adaptability of the rice transplanter and cannot well meet the needs of rice planting. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, multiple rice transplanting rods with adjustable angles are installed on the rice transplanting shaft. As the transplanting shaft rotates, the spacing between seedlings is positioned and controlled by the rice transplanting rods at different angles. This allows for control of the number of seedlings in the soil based on soil conditions, preventing insufficient nutrient supply to the seedlings due to an excessive number of seedlings and improving the rice planting effect.

[0017] In this invention, a hydraulic component is installed in the rice transplanter to drive the entire fixed frame for height adjustment, thereby positioning the depth of the seedlings during transplanting and forming a double positioning structure for the seedlings. Combined with an adjustable seedling feeding plate, this stabilizes the feeding effect of the seedlings, improves the adaptability of the rice transplanter, and thus better meets the needs of rice planting.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, firstly, the rice seedlings to be transplanted are placed into the feeding groove on the feeding plate 603 inside the feeding bin 6; then, the bottom ends of multiple transplanting rods 504 are sequentially aligned with the corresponding positions of the positioning grooves 502 inside the transplanting seat 501, and fixed with the positioning holes 503 using positioning bolts 505 and positioning nuts 506 to fix the angle of the multiple transplanting rods 504, thereby positioning the spacing between the seedlings during transplanting; next, the hydraulic component 104 is activated to drive the fixing frame 2 to rise and fall, positioning the transplanting height, and after positioning, the limit nuts 202 are used in conjunction with the limit grooves 10 on both sides. The limiting screw 201 inside 3 provides auxiliary fixation. After the docking component 101 at one end of the movable bracket 1 is docked with the movable end, the preparation work before transplanting is completed. Finally, the transplanting motor 3 is started to drive the transplanting shaft 4 to rotate, which in turn drives the U-shaped seedling taking port at one end of the transplanting rod 504 to take seedlings from the seedling taking trough 601 and rotate to the bottom for transplanting. At the same time, the adjusting motor 606 is started to drive the adjusting threaded shaft 607 to rotate, which in turn drives the first adjusting block 608 to link with the second adjusting block 610 at one end of the adjusting rod 609 to adjust the angle of the seedling feeding plate 603, thereby controlling the seedling taking of the transplanting rod 504.
