No-till seeders usually include two parts: a fertilizer discharge and furrowing mechanism and a sowing and furrowing mechanism. For example, a no-till seeder is disclosed in the Chinese utility model patent with the authorization announcement number CN204014455U. The fertilizer discharge and opening mechanism of the no-till seeder includes a fertilizer discharge and furrowing device, a fertilizer box, a fertilizer discharge pipe, a fertilizer discharger and other structures. The sowing and furrowing mechanism of the no-till seeder includes a sowing and furrowing device, a seed box, a seed discharger and other structures. For another example, a two-row anti-blocking no-till seeder is disclosed in the Chinese utility model patent with the authorization announcement number CN206413391U. The two-row anti-blocking no-till seeder includes a stubble-killing device, a fertilizer furrowing device, a depth-limiting wheel, a driving wheel, a seed discharge furrowing device, a seed discharger, a contoured four-bar mechanism, a fertilizer box and other structures. When the two-row no-till seeder is working, the tractor pulls the two-row no-till seeder forward and drives the stubble-killing device to rotate at high speed to cut off the straw. The power for fertilizing and sowing is provided by the driving wheel. The Chinese invention patent with publication number CN102385318A discloses a method and device for controlling the sowing amount of a no-till planter, which is equipped with a special seeding motor controller and seeding servo motor as well as a fertilizer motor controller and fertilizer servo motor to replace the traditional method of using a driving wheel to provide fertilization and seeding power, so as to cooperate with an on-board computer, an on-board GPS positioning navigation system, a variable sowing feedback device, a precision fertilization control device and other devices to achieve the purpose of precise sowing and fertilization.

The utility model can use the same method to achieve control of the above-mentioned first servo motor 301 and the second servo motor 201. In this way, the utility model can achieve precise output of a single type of fertilizer according to actual needs, and can also achieve mixed output of two fertilizers, thereby improving the scope of application and flexibility of use of the utility model.

[0036] The working principle of the utility model is:

[0037] When the utility model is working, different fertilizer cavities in the fertilizer box 1 can hold different types of fertilizers according to actual needs. For example, the left and right fertilizer cavities of the first fertilizer cavity 101 hold organic fertilizers, and the left and right fertilizer cavities of the second fertilizer cavity 102 hold chemical fertilizers. In this way, the utility model can control the corresponding fertilizer discharge shaft to rotate and apply fertilizers according to needs, and the use is more flexible.

Due to the spiral of the left conveying spiral piece 1501 and the right conveying spiral piece 1601, the fertilizer in the fertilizer box 1 can be directly delivered to the fertilizer box 1. The rotation directions are opposite, so the utility model can drive the corresponding left conveying spiral piece 1501 and the right conveying spiral piece 1601 to rotate synchronously through a fertilizer discharge shaft, thereby ensuring that the fertilizer applied to the furrows on both sides of the two-row no-till seeder is equal. In addition, the utility model uses the first drive component and the second drive component to respectively control the rotation of the corresponding fertilizer discharge shaft, which is convenient for control and also conducive to subsequent system upgrades and use. For example, the utility model can adopt the control method in the CN102385318A authorized invention patent, which is used to control the precise output of seeds and fertilizers. The utility model can adopt the above method to control the precise output of two fertilizers, thereby further improving the accuracy of fertilization.
