[0002] With the rapid development of modern agricultural technology, the requirements for sowing accuracy and efficiency are increasing day by day when sowing corn. As one of the important food crops in my country, corn's sowing method and technical level directly affect the yield and quality of corn. The existing spoon seeder cannot sow seeds of different specifications. It must be disassembled and replaced with a spoon wheel, which is very cumbersome. In addition, the existing seeder can only sow one seed at a time, and the corresponding seed guide wheel needs to be replaced to sow other quantities of seeds.

[0003] In view of the problems of the prior art, the utility model is improved and designed. When the utility model is in use, the number of particles of seed feeding can be adjusted. Each seed taking spoon corresponds to a grid on the seed guide wheel. The number of grids corresponding to the seed taking spoon can be controlled by adjusting the distance between the partitions I, II and III. When the partition I is adjusted to coincide with the partition II, and the partition III and the partition below the partition III coincide with each other, each two seed taking spoons correspond to one grid, that is, two seeds are fed. When the partitions I, II and III are adjusted to coincide with the partition below the partition III, each four seed taking spoons correspond to one grid, that is, four seeds are fed. Therefore, there is no need to replace the guide wheel to achieve the control of the number of seeds planted, especially four seeds, which is to achieve dense planting on the basis of sparse planting, and can achieve the optimal planting mode; the utility model can also control the depth of the seed taking spoon by controlling the lifting of the bottom film in the seed taking spoon, so as to achieve adaptation to seeds of different specifications, and the utility model can remove excess seeds on the seed taking spoon to ensure that there is only one seed in the seed taking spoon, to achieve precise control, and directly connected to the external power through the transmission shaft, through the precise control of the PLC, the sowing spacing can be accurately controlled at 40-50CM.

[0038] In an optional implementation of the present utility model embodiment, as Figure 6 As shown, a plurality of through holes are provided below the seed taking spoon 4 to allow impurities to leak out.

[0039] In an optional implementation of the present utility model embodiment, as Figure 2 As shown, each grid on the seed guide wheel 19 is aligned with each seed taking spoon 4.

[0040] Working principle: When the utility model is used, firstly, the seeds are loaded into the transparent shell 30 through the feed port 32, and the transmission shaft 34 is driven to rotate by external power, thereby driving the synchronous rotation of the spoon wheel 1 and the seed guide wheel 19, and the seed taking spoon 4 on the spoon wheel 1 takes up the seeds in the transparent shell 30 when rotating, and each seed taking spoon 4 rotates to a horizontal position, and the push plate 13 behind the spoon wheel 1 just passes the inclined surface protrusion 16, and the inclined surface protrusion 16 squeezes the push plate 13, so that the push plate 13 takes the seeds Any excess seeds on the spoon 4 are pushed down, so as to ensure that there is only one seed on each seed taking spoon 4. After the push plate 13 passes the inclined protrusion 16, it is reset under the action of the flat spring 15. When the seed taking spoon 4 rotates to the spring piece 3, the spring piece 3 passes through the notch on the seed taking spoon 4 and pushes the seeds inside to the corresponding grid on the seed guide wheel 19. The seeds fall into the grid. When the grid with seeds falling on the seed guide wheel 19 rotates to the bottom, the seeds will fall into the sowing ground through the outlet hole at the bottom of the main shell 31.

[0041] The device can adapt to different seed specifications by adjusting the depth of the film 6 in the seed taking spoon 4. Specifically, before use, open the transparent shell 30, manually move the round rod on the telescopic rod 10, so that the telescopic rod 10 slides out of the original notch of the gear slot 9, and then move the round rod on the telescopic rod 10 to rotate the lever II 11, so that the telescopic rod 10 is stuck in the other notch of the gear slot 9, and the rotation of the lever II 11 drives the ring 7 to rotate, and the ring 7 drives the lever I 5 to rotate, so that the film 6 is driven by the lever I 5 to slide and rise in the seed taking spoon 4, so as to adjust the depth in the seed taking spoon 4, so that seeds of different specifications can adapt to the space of the seed taking spoon 4;

[0042] The utility model can also adjust the width of the grid on the seed guide wheel 19 to achieve the number of seeds that can fall from each grid. Before use, the telescopic plate 27 is manually pulled out, and then the telescopic plate 27 is pulled to drive the partition I 20 to rotate in the slide groove of the seed guide wheel 19. When the partition I 20 moves to the partition II 21 and stops, the notch on the partition II 21 passes through the convex plate II 29, and then the telescopic plate 27 is reset in the slide groove of the partition I 20, and the telescopic plate 27 will jam the convex plate II 29 to prevent the partition I 20 from retreating. When the partition I 20 moves to the partition II 21, the spring I 23 on the partition I 20 is compressed to generate elastic force. At this time, the spring I 23 will squeeze the partition III 22 to move, so that the partition III 22 contacts the next adjacent partition of the partition III 22, and the spring III 25 is compressed, and the elastic force of spring Ⅰ23 after compression is much greater than the elastic force of spring Ⅲ25; in this way, the two partitions overlap with the other two adjacent partitions, and the four grids become two, and each grid will have two seeds; similarly, continue to move partition Ⅰ20, so that partition Ⅰ20, partition Ⅱ21, and partition Ⅲ22 can overlap with the next partition adjacent to partition Ⅲ22, so that the previous two grids become a large grid, and this large grid changes from four to one, so that four seeds can fall. When one seed is needed, partition Ⅰ20 can be reset. When resetting, under the action of spring Ⅰ23, spring Ⅱ24, and spring Ⅲ25, partition Ⅰ20, partition Ⅱ21, and partition Ⅲ22 are moved to the original position, and when resetting, Fig. 9 As shown, partition I 20 is shorter than partition II 21, and partition II 21 is shorter than partition III 22. There are protrusions at the initial positions of partition II 21 and partition III 22 that can clamp partition II 21 and partition III 22 accordingly, thereby preventing partition II 21 and partition III 22 from being over-reset.
