DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a rice transplanter with adjustable planting spacing, comprising a rice placing plate 1 and a fixed rice transplanting head 9 located at the lower side of the front end of the rice placing plate 1, and a movable rice transplanting head 13 located at the outer side of the left end of the mounting shaft 8, and also comprising a baffle 2 integrally fixedly installed at the side of the rice placing plate 1, and a first mounting plate 3 is welded on the outer end of the baffle 2, and a second mounting plate 4 which is also located on the outer side of the baffle 2 is arranged directly below the first mounting plate 3, a driving motor 5 is arranged on the outer side of the right arm of the second mounting plate 4, and a transmission shaft 6 is arranged at the output end of the driving motor 5;

[0025] At the same time, the connecting plate 7 is fixedly installed on the outer end of the transmission shaft 6, and the left side of the end of the connecting plate 7 away from the transmission shaft 6 is fixedly installed with a mounting shaft 8 that runs through the fixed transplanting head 9, the outer side of the rear end of the fixed transplanting head 9 is fixedly installed with a mounting frame 10 by screws, and the outer sides of the left and right ends of the mounting frame 10 are connected to support plates 11, the outer side of the rear end of the movable transplanting head 13 is fixedly installed with a connecting block 14 located in the mounting frame 10, and the connecting block 14 and the mounting frame 10 are both provided with fixing bolts 15, the upper end of the support plate 11 is internally rotatably penetrated by a limiting rod 12, the front end of the mounting frame 10 is provided with a threaded groove 16 that matches the fixing bolt 15, and the lower end of the connecting block 14 is fixedly installed with a limiting block 17, which is combined to form a rice transplanter with adjustable planting spacing.

[0026] When using the rice transplanter with adjustable planting spacing, the specific Figure 1 and Figure 2 As shown in the figure, first, the seedling placing plate 1 is fixedly installed on the front outer side of the walking mechanism by screws, and then the rice seedlings required for transplanting are placed on the outer side of the upper end of the seedling placing plate 1, so that the rod-shaped structure arranged on the inner side of the lower end of the seedling placing plate 1 can shield the seedlings to prevent them from falling, and at the same time, the roots of the rice seedlings can extend out of the rod-shaped structure under the action of gravity, so that the subsequent fixed transplanting head 9 and the movable transplanting head 13 can transplant the rice seedlings.

[0027] Combination Figure 3As shown in the figure, since the mounting shaft 8 is connected to the fixed transplanting head 9 in a rotating manner, and the mounting frame 10 forms a rotating structure with the support plate 11 through the hinge shaft, the driving motor 5 is started, so that the driving motor 5 and the transmission shaft 6 drive the connecting plate 7 and the mounting shaft 8 to rotate. At this time, the mounting shaft 8 can drive the fixed transplanting head 9 and the mounting frame 10 to rotate outside thereof, so that the front end of the fixed transplanting head 9 can be rotated to the front lower end of the seedling placing plate 1 and the rice seedlings are inserted downward into the rice field. After the transplanting is completed, the fixed transplanting head 9 is driven by the mounting shaft 8. The class rotates to the original position, and then reciprocates the movement. Similarly, when the fixed transplanting head 9 rotates again, it can drive the multiple groups of movable transplanting heads 13 arranged on its left side to move synchronously with it, so as to improve the overall transplanting effect. When the fixed transplanting head 9 rotates, the mounting frame 10 rotates with the support plate 11 through the hinge shaft, and drives the upper end of the support plate 11 to rotate outside the limiting rod 12. At this time, the support plate 11 and the limiting rod 12 can limit and support the fixed transplanting head 9 and the mounting frame 10, so as to facilitate better transplanting work.

[0028] Specific as Figure 1 and Figure 4 As shown in the figure, since the interior of the mounting frame 10 is provided with a groove structure adapted to the connecting block 14, and the connecting block 14 is connected to the mounting frame 10 in a sliding manner through the groove structure, when the planting spacing needs to be adjusted, the fixing bolt 15 can be rotated to make the fixing bolt 15 threadedly connected and separated with the connecting block 14 and the threaded groove 16, and then the position of the movable transplanting head 13 is adjusted, so that the movable transplanting head 13 drives the connecting block 14 and the limit block 17 to move in the mounting frame 10 for adjustment. After the adjustment is completed, the fixing bolt 15 is inserted into the threaded groove 16 relative to the position, so as to facilitate the fixing of the positions of the connecting block 14 and the movable transplanting head 13 by the fixing bolt 15, and then facilitate the more flexible adjustment of the planting spacing of the rice seedlings. This is the method of using the rice transplanter with adjustable planting spacing.
