[0002] When conducting a corn seed germination experiment, the sowing depth should not be too deep according to the germination conditions of the corn seeds. Sowing too deep can easily extend the germination time and increase the experimental period. If the soil moisture is too high and the sowing is too deep, the seeds may have difficulty breathing, rot and fail to germinate. At the same time, in order to ensure normal growth conditions for corn, the corn seeds need to be sown at a fixed spacing to ensure the nutrient absorption of each seed.

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.
[0026] A seed germination experimental device, such as Figure 1 , Figure 2 As shown, it includes an experimental cabinet 10, in which a plurality of mounting plates 13 are fixedly installed in the cavity of the experimental cabinet 10, a seedling box 12 is placed above each mounting plate 13 and on the bottom wall of the cavity of the experimental cabinet 10, and experimental soil is added in the seedling box 12, and air-permeable nets 11 for ventilation and exhaust are installed on the side walls of the experimental cabinet 10; a plurality of mechanical arm assemblies 20 for guiding movement are arranged on the bottom wall of the mounting plate 13, and a trenching assembly 30 for trenching, sowing and covering soil is arranged below each mechanical arm assembly 20, and the trenching assembly 30 includes a shovel block 31 for inserting into the experimental soil, and a sowing structure for directional sowing of seeds is arranged on the shovel block 31.
[0027] like Figure 3 , Figure 4 As shown, the mechanical arm assembly 20 includes a guide frame 21 fixedly mounted on the bottom wall of the mounting plate 13, a threaded rod 22 is rotatably mounted in the bottom cavity of the guide frame 21, a first motor 23 for driving the threaded rod 22 to rotate is fixedly mounted on one side wall of the guide frame 21, a threaded sleeve 24 is threadedly connected to the threaded rod 22, the threaded sleeve 24 is engaged in the cavity of the guide frame 21, and a connecting plate 25 is fixedly arranged at the bottom of the threaded sleeve 24. The bottom of the connecting plate 25 is fixedly connected to a cylinder 26, and the bottom of the piston rod of the cylinder 26 is fixedly mounted with a bracket 33 for connecting a shovel block 31, and the bottom of the shovel block 31 is conical. Two symmetrical soil guide plates 32 are also fixedly mounted on one side wall of the shovel block 31, and the soil guide plates 32 are in a multi-section curved state.
[0028] like Figure 5 , Figure 6 and Figure 7 As shown, the sowing structure includes a seed barrel 36 fixedly mounted on the shovel block 31, the bottom of the seed barrel 36 is conical, and a vertical downward guide pipe 37 is fixedly connected to the conical bottom of the seed barrel 36, the guide pipe 37 vertically penetrates the shovel block 31, and a discharge pipe 39 is fixedly connected to the bottom of the guide pipe 37, and the discharge pipe 39 is located on the bottom wall of the shovel block 31; an end cap 42 is threadedly connected to the seed barrel 36. A second motor 34 is fixedly mounted on the top wall of one side of the shovel block 31, and a rotating disk 35 is fixedly connected to the output end of the second motor 34. A notch 38 is opened at the position corresponding to the rotating disk 35 of the guide pipe 37, and the notch 38 is arc-shaped. A discharge port 40 corresponding to the size of the notch 38 is opened on one side wall of the rotating disk 35. The seed barrel 36 and the guide pipe 37 are transparent.
[0029] When in use, the experimental soil is added flatly into the corresponding seedling box 12. The first motor 23 is a forward and reverse rotating motor. Before trenching, sowing and covering the experimental soil, the trenching assembly 30 needs to be adjusted as a whole to one side of the cavity of the experimental cabinet 10, and the soil guide plate 32 of the shovel block 31 is also located on this side of the cavity of the experimental cabinet 10. Unscrew the end cover 42 on the seed barrel 36, put the corn seeds into the seed barrel 36, and the corn seeds will be arranged one by one through the guide tube 37.
[0030] By controlling the working switch of the first motor 23, the first motor 23 drives the threaded rod 22 to rotate slowly, so that the threaded sleeve 24 drives the connecting plate 25 to move slowly and uniformly. Before this, the working switch of the cylinder 26 is turned on, and the piston rod of the cylinder 26 drives the shovel block 31 to move downward. The conical bottom of the shovel block 31 is inserted into the experimental soil. The working state of the cylinder 26 can be adjusted according to the depth of the experiment.
[0031] After the shovel block 31 is inserted into the experimental soil, the shovel block 31 is driven by the connecting plate 25 to move at a uniform speed, so that the shovel block 31 can dig a groove in the soil, so that a planting groove can be dug out in the soil through which the shovel block 31 passes. At the same time, the working switch of the second motor 34 is turned on, and the second motor 34 drives the turntable 35 to rotate when it rotates. When the edge of the turntable 35 is located in the notch 38, the seeds in the guide pipe 37 can be blocked. When the discharge port 40 rotates into the notch 38, the seeds at this time will fall down, and the fallen seeds can fall into the grooved soil through the guide pipe 37 and the discharge pipe 39, thereby realizing automatic and uniform sowing.
[0032] At the same time, after the sowing is completed, the shovel block 31 will continue to move. The further movement of the shovel block 31 in the soil, under the guidance of the soil guide plate 32, allows the soil turned up on both sides of the shovel block 31 to be guided by the soil guide plate 32 to the ditch where the seeds have just been sown, so that the seeds are automatically covered with soil. After completion, all preparations for the seed germination experiment can be completed, and finally appropriate moisture is sprayed on the soil so that the seeds can germinate better.
