[0035] Please refer to Figure 1 A base soil laying device includes a conveying device 1, a sowing component 2 is installed on the top of the conveying device 1, and two soil laying components 3 are also installed on the top of the conveying device 1. The two soil laying components 3 are respectively located at the two ends of the sowing component 2, and the two soil laying components 3 are symmetrically arranged. A stirring component 4 is installed on the inner side of the sowing component 2.

[0036] The conveying device 1 serves to carry the sowing assembly 2 and the soil spreading assembly 3, and also serves to convey the cultivation tray;

[0037] The sowing component 2 plays the role of evenly sowing the seeds, thereby improving the cultivation effect of rapeseed;

[0038] The soil laying component 3 plays the role of laying the base soil. Through the setting of the soil laying component 3, the laying thickness of the base soil can be adjusted, so that the base soil laying device is suitable for cultivation trays of more specifications, thereby improving the working efficiency of the base soil laying device;

[0039] The stirring component 4 is used to stir the seeds inside the sowing component 2, thereby preventing the seeds from being accumulated inside the sowing component 2 and being damaged, thereby improving the subsequent effect of rapeseed cultivation;

[0040] During the process of laying the base soil, the cultivation tray can be placed on the top of the conveying device 1, and the conveying device 1 drives the cultivation tray to pass through the first soil-laying component 3 to lay the base soil for the first time, and then continues to drive the cultivation tray to move to the bottom of the sowing component 2, and the inner side of the cultivation tray is evenly sown through the setting of the sowing component 2, and then the conveying device 1 continues to drive the cultivation tray to move to the bottom of the second soil-laying component 3 to lay the base soil for the second time, covering the sown seeds, thereby completing the work of laying the base soil inside the cultivation tray.

[0041] Embodiment 2:

[0042] This embodiment 2 is used to further disclose the specific structure of the sowing component 2 and the soil-laying component 3 on the premise of the above-mentioned embodiment. Through the coordination of the sowing component 2, the soil-laying component 3 and the structures in the above-mentioned embodiment, the base soil laying device can perform continuous laying operations during operation, thereby improving the working efficiency of the base soil laying device. At the same time, the seeds can be automatically scattered evenly, thereby further improving the working efficiency of the base soil laying device.

[0043] The base soil laying device provided in Example 1 is further optimized. Specifically, Figure 2-7 As shown, the sowing assembly 2 includes a seed collecting box 5 and a leakage plate 6. A filter plate is fixedly connected to the inner bottom of the seed collecting box 5. Two leakage plates 6 are arranged at the inner bottom of the seed collecting box 5. The two leakage plates 6 are both located below the filter plate, and the two leakage plates 6 are symmetrically arranged, and the two leakage plates 6 are respectively arranged with a gap fit at both ends of the inner bottom of the seed collecting box 5.

[0044] The sowing component 2 also includes a fixed plate 7, a spring 8 and a semi-arc extrusion block 9. The ends of the two leakage plates 6 located on the outside of the seed collecting box 5 are fixedly connected to the fixed plate 7, and the fixed plate 7 is located at the ends of the two leakage plates 6 away from each other. The end of the fixed plate 7 close to the seed collecting box 5 is fixedly connected to a plurality of springs 8, and the ends of the springs 8 away from the fixed plate 7 are fixedly connected to the seed collecting box 5. The center position of the end of the fixed plate 7 away from the seed collecting box 5 is fixedly connected to a semi-arc extrusion block 9.

[0045] The sowing component 2 also includes a support vertical plate 10, a support horizontal plate 11, a first motor 12 and an elliptical extrusion disk 13. The support vertical plates 10 are fixedly connected on both sides of the top ends of the conveying device 1, and the support vertical plates 10 are located between the seed collecting box 5 and the soil spreading component 3. A support horizontal plate 11 is arranged between every two support vertical plates 10. Both sides of the support horizontal plate 11 are fixedly connected to every two support vertical plates 10. The first motor 12 is fixedly connected to the top of the support horizontal plate 11. The elliptical extrusion disk 13 is fixedly connected to the top of the first motor 12, and the elliptical extrusion disk 13 is extrusion-fitted with the semi-arc extrusion block 9.

[0046] Specifically: by turning on the first motor 12, the elliptical extrusion disk 13 can be driven to rotate, so that the setting of the elliptical extrusion disk 13 can cause an extrusion effect on the semi-arc extrusion block 9, and the semi-arc extrusion block 9 can be moved toward one end close to the seed collecting box 5, so that the semi-arc extrusion block 9 can cause a pushing effect on the fixed plate 7, and the connection setting of the fixed plate 7 can drive the leakage plate 6 to slide in the gap at the bottom of the seed collecting box 5, so as to achieve the intermittent blocking and leakage effect on the filter plate at the bottom of the inner side of the seed collecting box 5, and then the seeds inside the seed collecting box 5 can be made to fall evenly to the inner side of the cultivation disk;

[0047] When the fixed plate 7 approaches the seed collecting box 5, it can cause an extrusion effect on the spring 8 and make the spring 8 produce an elastic deformation effect. Subsequently, when the elliptical extrusion disk 13 rotates to an angle that is out of the extrusion effect on the semi-arc extrusion block 9, the elastic action of the spring 8 can push the fixed plate 7 toward the end away from the seed collecting box 5, and make the fixed plate 7 drive the semi-arc extrusion block 9 to move to the position before the elliptical extrusion disk 13 pushes it, thereby preparing for the next time the elliptical extrusion disk 13 pushes the semi-arc extrusion block 9.

[0048] The soil laying assembly 3 includes a first support plate 14, a second support plate 15, a fixed connecting plate 16 and a soil collecting box 17. The first support plates 14 are fixedly connected to both sides of the top of one end of the conveying device 1, and the two first support plates 14 are located at the end of the support vertical plate 10 away from the seed collecting box 5. The second support plates 15 are fixedly connected to both sides of the top of the other end of the conveying device 1, and the two second support plates 15 are located at the end of the other group of support vertical plates 10 away from the seed collecting box 5. The fixed plate 7 is fixed on both sides of the end away from the seed collecting box 5. A fixed connecting plate 16 is connected, and one end of each two fixed connecting plates 16 away from the fixed plate 7 is fixedly connected to a soil collecting box 17. The two soil collecting boxes 17 are symmetrically arranged, and the two soil collecting boxes 17 are respectively arranged with clearance fit between the two first support plates 14 and the two second support plates 15. Movable grooves are provided on the inner sides of the first support plate 14 and the second support plate 15 on the same side, and the movable grooves correspond to the bottom positions of the soil collecting boxes 17 and are arranged through both ends of the first support plate 14 and the second support plate 15.

[0049] The soil paving assembly 3 also includes a rotating closing plate 18, a first rotating rod 19, a second rotating rod 20, a transmission belt 21, a gear 22 and a second motor 23. The bottom of each soil collecting box 17 is rotatably connected to two rotating closing plates 18, and both ends of each rotating closing plate 18 close to the movable groove are fixedly connected to the first rotating rod 19, and the first rotating rod 19 is located on the inner side of the movable groove. The middle part of the bottom of each soil collecting box 17 close to the movable groove is rotatably connected to two second rotating rods 20, and two transmission belts 21 are provided on the inner side of the movable groove, and each first rotating rod 19 and each second rotating rod 20 are Through each transmission belt 21, a gear 22 is fixedly connected to the outer side of each second rotating rod 20, and the two gears 22 are meshingly arranged. Each first support plate 14 and the second support plate 15 with a movable groove are slidably connected to a second motor 23 through a slideway on the side away from the soil collecting box 17. The first support plate 14 and the second support plate 15 with a movable groove are both provided with a sliding groove on the side away from the soil collecting box 17, and the sliding groove and the movable groove are connected. The output end of each second motor 23 passes through the sliding groove and is fixedly connected to the corresponding first rotating rod 19.

[0050] Through the linkage setting of the fixed connecting plate 16, when the elliptical extrusion plate 13 pushes the semi-arc extrusion block 9 to drive the fixed plate 7 to move back and forth, the soil collecting box 17 is driven to slide back and forth between the first support plate 14 and the second support plate 15, thereby vibrating and loosening the base soil inside the soil collecting box 17, so that the subsequent base soil laying effect is more uniform;

[0051] When the cultivation tray moves to the bottom of the soil collecting box 17, the second motor 23 can be turned on to drive the first rotating rod 19 to rotate. At the same time, through the setting of the transmission belt 21, the second rotating rod 20 connected to the first rotating rod 19 is driven to rotate while the first rotating rod 19 rotates. At this time, the gear 22 outside the second rotating rod 20 will rotate synchronously;

[0052] Because the two gears 22 are gear meshing arrangements, when one of the gears 22 rotates, it will drive the other gear 22 to rotate synchronously in the opposite direction, and then drive the other second rotating rod 20 and the transmission belt 21 to rotate in the opposite direction, thereby driving the other first rotating rod 19 to rotate in the opposite direction. At this time, the two rotating closing plates 18 fixedly connected to the two first rotating rods 19 will produce synchronous opposite rotation through the opposite rotation of the two first rotating rods 19, thereby producing an effect of opening a gap at the bottom of the soil collecting box 17, so that the base soil inside the soil collecting box 17 can flow into the inside of the cultivation tray;

[0053] By controlling the length of time the second motor 23 is turned on, the gap between the two rotating closing plates 18 is controlled to control the flow rate of the base soil flowing out. When cultivation trays of different specifications are placed at the bottom of the soil collecting box 17, the base soil in the cultivation tray can be evenly laid, thereby expanding the application range of the base soil laying device and improving the working efficiency of the laying device.

[0054] Embodiment 3:

[0055] This embodiment 3 is used to further disclose the specific structure of the stirring component 4 on the premise of the above embodiments. Through the coordination of the stirring component 4 and the structure in the above embodiments, the seeds accumulated inside the base soil laying device can be stirred, thereby avoiding the phenomenon of damage caused by seed accumulation, thereby improving the subsequent cultivation effect.

[0056] The base soil laying device provided in Example 1 and Example 2 is further optimized. Specifically, Figure 2 As shown, the stirring assembly 4 includes a third rotating rod 24, a stirring blade 25 and a third motor 26. The third rotating rod 24 is rotatably connected to the inner side of the seed collecting box 5, and two stirring blades 25 are fixedly connected to the outer side of the third rotating rod 24. A third motor 26 is arranged on one side of the seed collecting box 5, and the output end of the third motor 26 passes through the side wall of the seed collecting box 5 and is fixedly connected to the end of the third rotating rod 24.

[0057] By turning on the third motor 26, the third rotating rod 24 is driven to rotate, thereby driving the two stirring blades 25 to rotate inside the seed collecting box 5, stirring the seeds inside the seed collecting box 5, reducing damage to the seeds inside the seed collecting box 5 due to accumulation, and reducing the phenomenon of seeds adhering to the inner surface of the seed collecting box 5, thereby reducing the waste of resources.
