When the vibration motor 10 is energized, it drives the cultivation tray 3 to vibrate left and right. A sink cavity 11 is provided on the top of the cultivation tray 3. The top of the cultivation trough 4 coincides with the bottom of the sink cavity 11 on the same plane. The left and right ends of the sink cavity 11 are connected. A cultivation bucket 12 is installed on the right end of the sink cavity 11 through a hinge shaft 23. The length of the cultivation bucket 12 is greater than the opening range of the cultivation trough 4. The cultivation bucket 12 is located above the cultivation trough 4, and the top opening of the cultivation bucket 12 faces upward. The bottom surface of the cultivation bucket 12 is sealed with a screen 14. The cultivation bucket 12 is filled with cultivation materials. When the free end of the cultivation bucket 12 rotates into the sink cavity 11, the screen 14 is under the action of the gravity of the cultivation material, so that its bottom surface coincides with the top opening of the cultivation trough 4.

[0032] An installation area 15 is provided in the middle of the cultivation tray 3, and the cultivation tanks 4 are distributed on the left and right sides of the installation area 15 in a left-right symmetrical manner. The vibration motor 10 is fixed on the bottom surface of the installation area 15. When the vibration motor 10 is installed, its vibration direction is left-right vibration.

[0033] The cultivation groove 4 is a trapezoidal deep groove which gradually narrows downwards.

[0034] The rotating rod 6 is a cylindrical tube, the top of which is closed and fixed with a turntable 16. The bottom of the turntable 16 rotates and contacts the bottom of the cultivation tank 4. There are at least three uniform rods 8, which are fixed on the turntable 16 in a circular array and extend vertically along the depth direction of the cultivation tank 4. A drainage hole 17 is provided in the middle position of the rotating rod 6. The drainage hole 17 is communicated with the tubular cavity of the rotating rod 6, and the bottom end of the rotating rod 6 is communicated with the drainage hole 17 through the tubular cavity.

[0035] A stepped hole 20 is provided at the bottom of the cultivation tank 4, and the top end of the rotating rod 6 enters into the cultivation tank 4 through the stepped hole 20. The turntable 16 rotates in the stepped hole 20, and the top surface of the turntable 16 coincides with the bottom of the cultivation tank 4, and the outer cylindrical surface of the turntable 16 coincides with the hole wall of the stepped hole 20 through rotation.

[0036] Tread wheels 13 are installed on some of the cultivation troughs 4 on both sides through rotating shafts, and pedals 18 are provided on the outer sides of the racks 9 on both sides. The tread wheels 13 roll in contact with the pedals 18. When the cultivation tray 3 vibrates left and right with the cultivation trough 4, the tread wheels 13 also move left and right along the pedals 18.

[0037] Working principle and effect: Rotate the cultivation bucket 12 around the hinge shaft 23 into the sink cavity 11, and cover the cultivation groove 4 with the screen 14 at the same time, fill the bottom nutrient soil into the cultivation bucket 12, and smooth it along the screen 14, start the vibration motor 10, the vibration motor 10 generates vibration, and transmits the vibration effect to the cultivation plate 3, and the cultivation plate 3 transmits the vibration effect to the spring seat 2, and the spring seat 2 amplifies the vibration and transmits the vibration effect to the cultivation plate 3, so that the cultivation plate 3 vibrates left and right with the cultivation bucket 12, and the cultivation bucket 12 vibrates left and right with the screen 14 (screening), so that the bottom nutrient soil is evenly screened through the screen 14 and falls into each cultivation groove 4, and the cultivation bucket 12 is rotated upward around the hinge shaft 23 to expose all the cultivation grooves 4 on the cultivation plate 3, and the vibration motor 10 is turned off. Then, the improved varieties are placed in each cultivation tank 4 in groups of two, and then the cultivation bucket 12 is rotated into the sink cavity 11 again, the screen 14 is covered on the cultivation tank 4 again, the upper nutrient soil is filled into the cultivation bucket 12 and smoothed, and the vibration motor 10 is started. The vibration motor 10 vibrates again and transmits the vibration effect to the cultivation tray 3, and the cultivation tray 3 transmits the vibration effect to the spring seat 2, and the spring seat 2 amplifies the vibration and transmits the vibration effect to the cultivation tray 3, so that the cultivation tray 3 vibrates left and right with the cultivation bucket 12, and the cultivation bucket 12 vibrates left and right with the screen 14 (screening), so that the upper nutrient soil is sieved and falls into each cultivation tank 4 to cover the improved varieties, and the cultivation is completed. In summary, when the bottom nutrient soil and the upper nutrient soil are put into the cultivation tank 4, the soil layer is evenly distributed to all the cultivation tanks 4 by the vibration of the cultivation bucket 12, which not only improves the cultivation quality and efficiency of the soil layer, but also reduces the labor intensity during the soil application process.

[0038] When the cultivation tray 3 vibrates left and right, it will also move the cultivation trough 4 left and right, and the cultivation trough 4 will move the tread wheel 13 left and right, and the tread wheel 13 will roll left and right along the pedal 18 to ensure that the cultivation tray 3 vibrates left and right stably, so that the soil layer in the cultivation bucket 12 is filled into each cultivation trough 4 in the form of a vibrating screen. The cultivation trough 4 will also move left and right with each rotating rod 6, and the rotating rod 6 will move left and right with the gear 7. Since the gear 7 is meshed with the rack 9, the gear 7 will rotate with the rotating rod 6, and the rotating rod 6 will rotate the turntable 16, and the turntable 16 will rotate with the uniform rod 8. The top of the uniform rod 8 reaches one-third of the depth of the cultivation trough 4. The rotation of the uniform rod 8 is used to stir the bottom nutrient soil that falls into the cultivation trough 4 evenly, and ensure that the upper surface of the bottom nutrient soil tends to be horizontal. When the improved varieties are placed in the cultivation trough 4, it can be ensured that the improved varieties fall on the upper surface of the bottom nutrient soil. When the nutrient soil falls into the cultivation trough 4 in a vibrating manner, it is ensured that the nutrient soil covers the improved varieties.

[0039] like Figure 1 , Figure 2 as well as Figure 7 As shown, a mixing rod 21 is installed on the cultivation bucket 12, and the middle part of the mixing rod 21 is located in the cultivation bucket 12 and fixed with a mixing screw 24, and the two ends of the mixing rod 21 extend to the front and rear sides of the cultivation bucket 12, and a large tread wheel 22 is fixed to the front and rear ends of the mixing rod 21. When the free end of the cultivation bucket 12 rotates into the sinking cavity 11, the large tread wheel 22 falls on the pedal 18. When the cultivation plate 3 vibrates left and right with the cultivation trough 4, in addition to moving the cultivation bucket 12 left and right, it also moves left and right along the pedal 18 with the large tread wheel 22 through the cultivation bucket 12. There are multiple mixing rods 21, and the multiple mixing rods 21 are equidistantly distributed along the length direction of the cultivation bucket 12, and the mixing screws 24 on the two mixing rods 21 are adjacent.

[0040] When the cultivation bucket 12 vibrates left and right (when vibrating and screening the soil toward the cultivation trough 4), it drives the large tread wheel 22 to vibrate left and right along the pedal 18. Under the friction of the pedal 18, the large tread wheel 22 will drive the mixing rod 21, and the mixing rod 21 will drive the mixing screw 24 to rotate, so as to loosen the soil layer in the cultivation bucket 12. As the cultivation bucket 12 vibrates left and right, the soil in the cultivation bucket 12 is facilitated to pass through the screen 14 evenly into each cultivation trough 4, ensuring smooth screening.

[0041] After completing the above-mentioned soil layer cultivation, water is sprayed into the cultivation bucket 12. The cultivation bucket 12 vibrates left and right so that the water can be evenly distributed in each cultivation groove 4. As the water volume increases, excess water seeps into the tubular cavity of the rotating rod 6 through the drainage hole 17 and is discharged downward from the bottom end of the tubular cavity of the rotating rod 6.

[0042] The present invention also provides a breeding method of the composite corn breeding device, comprising the following breeding steps:

[0043] Step S01, mixing field mud and wood ash into nutrient soil to obtain a mixture, placing the mixture into a cultivation bucket 12 and smoothing it, and rotating the cultivation bucket 12 into the sink cavity 11 above the cultivation tank 4;

[0044] Step S02, start the vibration motor 10 to drive the cultivation plate 3 and the cultivation bucket 12 to vibrate left and right, and the mixture falls evenly into each cultivation tank 4 after being vibrated by the screen 14;

[0045] Step S03, placing corn seeds into each cultivation slot 4 of the cultivation tray 3, and cultivating two corn seeds in each cultivation slot 4;

[0046] Step S04, evenly sprinkle a layer of soil into the cultivation bucket 12 to cover the corn seeds;

[0047] Step S05, spray water into the cultivation bucket 12 to increase the humidity, start the vibration motor 10 again, drive the cultivation tray 3 and the cultivation bucket 12 to vibrate left and right, so that the soil and water are evenly distributed above the breeding.
