The frame 11, the metering bucket 5, the spreading plate 6, the seed drill 7, the pressing plate 8, and the nozzle 9 are arranged at equal intervals. The beaming photoelectric switch 15 can detect whether the tray 2 has moved to the position directly below the frame 11. When the tray 2 moves to the position of the beaming photoelectric switch 15, the tray 2 blocks the light of the beaming photoelectric switch 15. The beaming photoelectric switch 15 transmits a corresponding electrical signal to the controller 16, which controls the conveyor 1 to pause. During the pause of the conveyor 1, the paper padding, soil pouring, leveling, sowing, pressing down, and watering processes are performed simultaneously. The aforementioned controller 16 can be a PLC controller. The controller 16 can realize automatic control of the entire equipment, which is conducive to improving production efficiency.

[0038] In the present invention, the seed drill 7 includes a seed box 701, a second electric push rod 703, and a sealing plate 704.

In a preferred embodiment, the width of the sowing opening 7011 is approximately 1.5 times the average particle size of the sprout seeds. The upper end of the seed box 701 is provided with an open feeding port 7012, through which sprout seeds can be added to the seed box 701. One end of the first electric push rod 702 is connected to the seed box 701, and the other end of the first electric push rod 702 is connected to the mounting bracket 13.

Figure 4 As shown, the second electric push rod 703 can drive the sealing plate 704 to move to the right to open the sowing port 7011.

[0039] In the present utility model, the soil covering and bean sowing device also includes a first clamping plate 17, a second clamping plate 18, a first top cylinder 19 and a second top cylinder 20. The first clamping plate 17 and the second clamping plate 18 are located above the conveyor 1 and are respectively located on both sides of the spreading plate 6. The first top cylinder 19 and the second top cylinder 20 are respectively fixedly connected to the two side walls of the conveyor 1 and are electrically connected to the controller 16. The first clamping plate 17 is connected to the first top cylinder 19, and the second clamping plate 18 is connected to the second top cylinder 20. The first top cylinder 19 and the second top cylinder 20 can drive the first clamping plate 17 and the second clamping plate 18 to move closer to or away from each other. The first top cylinder 19 and the second top cylinder 20 can both use electric push rods. When the pallet 2 is located below the spreading plate 6, the first top cylinder 19 and the second top cylinder 20 drive the first clamping plate 17 and the second clamping plate 18 to approach each other, so that the pallet 2 is clamped between the first clamping plate 17 and the second clamping plate 18. The first clamping plate 17 and the second clamping plate 18 can clamp the pallet 2 to prevent the position of the pallet 2 from moving during the movement of the spreading plate 6. At the same time, the pallet 2 can also be positioned to prevent the push plate from being inserted into the outside of the pallet 2.

[0040] In the present invention, the pallet 2 has six stations on the conveyor 1. The six stations correspond to six different processes. The conveyor 1 transfers the pallet 2 between the six stations. The six processes are as follows:

[0041] Paper padding process: The tray 2 is located directly below the frame 11 (the first station). The third lifting cylinder 1002 drives the frame 11 down and places the padding paper sucked by the suction cup 12 into the tray 2. The third lifting cylinder 1002 then drives the frame 11 up. The third electric slide 1001 then drives the frame 11 to move above the loading platform 21. The third lifting cylinder 1002 then drives the frame 11 down and the suction cup 12 sucks the padding paper from the loading platform 21. The third lifting cylinder 1002 then drives the frame 11 up. The third electric slide 1001 then drives the frame 11 back to the top of the conveyor 1.

[0042] Soil pouring process: Tray 2 is located directly below the measuring hopper 5 (at the second station), the measuring hopper 5 is opened and a certain amount of culture soil is added into tray 2;

[0043] Leveling process: Tray 2 is located below the spreading plate 6 (the third station), the first lifting cylinder 302 drives the spreading plate 6 to descend and insert into the tray 2, and then the first electric slide 301 drives the spreading plate 6 to move horizontally to level the culture soil in the tray 2;

[0044] Sowing process: Tray 2 is located below the seeder 7 (the fourth station). The second electric push rod 703 drives the sealing plate 704 to move, so that the sowing port 7011 is opened, and the seeds in the seed box 701 fall from the sowing port 7011. Then the first electric push rod 702 pushes the seed box 701 to move, so that the sprout seeds are evenly sown on the culture soil of tray 2.

[0045] Pressing process: the tray 2 is located below the pressing plate 8 (the fifth station), the second driving assembly 4 drives the pressing plate 8 down to press the sprout seeds into the culture soil, and then the second driving assembly 4 drives the pressing plate 8 up and back to the initial position;

[0046] Watering process: Tray 2 is located below the sprinkler 9 (the sixth station), and water is poured into the tray 2 by the sprinkler 9, thus completing the entire soil covering and sowing process.

[0047] It is worth noting that trays 2 can be placed simultaneously at the six aforementioned workstations, allowing the six processes to proceed simultaneously, thereby ensuring high production efficiency of the soil-covered bean-sowing device. Furthermore, the paper padding process is optional; the paper padding placed inside the tray 2 is primarily for ease of cleaning. In some embodiments, the paper padding may not be placed inside the tray 2. The electric actuators used in this utility model can also be replaced by pneumatic actuators.

[0048] The soil covering and bean sowing device provided by the utility model can realize the full mechanization of soil cultivation of sprouts, reduce the number of workers, help reduce the planting cost of soil-cultivated sprouts, and promote the large-scale production of soil-cultivated sprouts. In addition, the utility model is conducive to realizing the standardized production of soil-cultivated sprouts and improving the stability of the quality of the sprouts.
