[0022] Reference Figure 1-Figure 3As shown, the present embodiment provides a sowing depth control device for peanut planting, comprising a first connecting plate 1, one end of the first connecting plate 1 is connected to the vehicle body, a plurality of ditching mechanisms are evenly spaced at the bottom of the first connecting plate 1 close to one end of the vehicle body, a seed box 2 is fixedly connected to the top surface of the first connecting plate 1 away from the vehicle body, a plurality of sowing mechanisms are evenly spaced at the bottom of the seed box 2, the sowing mechanism is located at the bottom of the first connecting plate 1, the sowing mechanism comprises a first connecting pipe 3 connected to the seed box 2, a first adjusting portion is provided on the first connecting pipe 3, a second adjusting portion is provided below the first connecting pipe 3, the second adjusting portion is fixedly connected to the first connecting plate 1, a plurality of soil covering mechanisms are evenly spaced at the bottom of the first connecting plate 1 away from the seed box 2, and a walking mechanism is fixedly connected to the four corners of the bottom surface of the first connecting plate 1.

[0023] When the device is used, the vehicle body pulls the first connecting plate 1 to move. When the sowing depth needs to be adjusted, the furrowing depth is first adjusted by the furrowing mechanism. After the adjustment is completed, the sowing depth is adjusted by the second adjusting part. At the same time, the sowing amount can be adjusted by the first adjusting part. After the sowing is completed, the soil after furrowing is restored by the soil covering mechanism. The present invention can not only adjust the planting depth of peanut seeds, but also adjust the sowing amount of peanut seeds, thereby improving the survival rate of peanut seeds.
