[0064] Specifically, refer to Figure 14 In the illustrated embodiment, the covering mechanism 900 includes a covering device 901 and a covering frame 902. The upper end of the covering frame 902 is connected with the bottom of the wheel chassis 100, and the lower end is connected with the covering device 901.

[0065] It should be noted that the multifunctional vacuum seeder further comprises a controller (not shown in the figure), and the controller is electrically connected with the driving motor 102c, the speed reduction motor air pump set 205, the rotary motor 501, the pesticide switch and the infrared detection device 1000.

[0066] The working principle of the multifunctional vacuum seeder is as follows:

[0067] In use, the seeds are first introduced into the air-suction seed metering mechanism 200 through the feeding opening 300, and then the seeds are sequentially adsorbed by the air-suction seed metering mechanism 200 by using negative pressure, and move to the guide chute 400 together with the air-suction seed metering mechanism 200, and then fall into the guide chute 400 under the blocking action of the guide chute 400, and then fall into the wheel chassis 100 through the guide chute 400 and are arranged on the disc distributing mechanism 500;

[0068] When the through hole 503 on the rotating baffle 502 of the disc distributing mechanism 500 is aligned with the seed, the seed will fall along the feeding rod 600 into the soil opened by the seedling cultivating mechanism 800, and at the same time, the infrared detection device 1000 will monitor the seed falling from the rotating baffle 502 in real time, and transmit the monitoring signal to the controller, and at this time, the controller will control the switch of the pesticide output mechanism 700 to open and release the pesticide to the seed sown into the soil.

[0069] When the seed in the soil receives the nutrient, the soil is covered on the seed by the soil covering mechanism 900, so that the seed is buried in the soil, and finally the soil is flattened by the rear roller 103a of the wheel chassis 100.

[0070] In the disc distributing mechanism 500, the rotating speed of the rotating baffle 502 is unchanged, and the rotating speed of the vacuum seed suction wheel 203 in the air-suction seed metering mechanism 200 is adjusted to be faster, so that more seeds enter the disc distributing mechanism 500, and vice versa, the rotating speed of the vacuum seed suction wheel 203 in the air-suction seed metering mechanism 200 is adjusted to be slower, so that the number of seeds entering the disc distributing mechanism 500 is reduced, so that the number of seeds in each seed hole can be accurately controlled.

[0071] In the case that the rotating speed of the vacuum seed suction wheel 203 is unchanged, the rotating speed of the rotating baffle 502 in the disc distributing mechanism 500 is adjusted to be faster, so that the seed falls faster, and in the case that the advancing speed of the seeder is unchanged, the distance between the front and rear seeds will be smaller, so that the seeding distance is reduced, and vice versa, the rotating speed of the rotating baffle 502 in the disc distributing mechanism 500 is adjusted to be slower, so that the seed falls slower, and in the case that the advancing speed of the seeder is unchanged, the distance between the front and rear seeds will be larger, so that the seeding distance is increased.

[0072] In addition, it should be noted that although there are currently vacuum seeders on the market, they are not widely used because the vacuum pump interface is easily damaged and the maintenance cost is high. In view of this, the applicant optimizes the connection mode of the vacuum pipe, significantly improves the durability of the vacuum seeder, and reduces the maintenance cost.

[0073] Finally, it should be noted that the above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
