the use and working principle is as follows:
1) starting a hub motor of the front wheel 20 to drive the whole vehicle to move forward;
2) when the trencher 60 moves to the side of one corn, controlling the hub motor of the front wheel 20 to stop the whole corn from moving forwards;
3) a force is applied to the sensor 160 by hand once.
The servo motor 80 drives the trencher 60 to rotate for a circle, and the trencher 60 digs the soil in the process of rotating for a circle. During the rotation process, as shown in fig. 3(c), when the trencher 60 rotates to the opening facing upwards, the fertilizer containing cavity 131 is opened downwards, and the fertilizer falls onto the soil in the trencher 60; continuing to rotate, as shown in fig. 3(d), the soil and fertilizer in the trencher 60 preferentially roll down to the upper right of the trench surface; as the trencher 60 continues to rotate, the soil in the trencher 60 rolls completely down into the trench;
4) after one-time ditching and fertilizing is completed, a hub motor of the front wheel 20 is started to enable the whole vehicle to move forward;
the rear wheel 30 shaped as a roller rolls the casing soil of the fertilizing groove in the forward rolling process.
Since the soil and fertilizer in the trencher 60 preferentially roll to the upper right of the trench surface if the trencher 60 is coaxially arranged with the trencher shaft 70, some fertilizer may be exposed at the uppermost side, resulting in insufficient soil coverage and easily losing nutrients through rain wash or sun exposure.

as shown in FIG. 4d, when the trencher 60 rotates more than 180 degrees, because the side surface of the semi-cylindrical plate 61 far from the blade is not attached to the trench surface, part of the soil in the trencher 60 begins to roll down to the upper right of the trench and then rolls down to the bottom of the trench through the gap between the side surface of the semi-cylindrical plate 61 and the trench surface, which is beneficial to storing all the fertilizer in the soil.
Further, the soil supporting cover 100 is also included;
the soil supporting cover 100 is a semi-cylindrical side surface, the soil supporting cover 100 is positioned above the trencher 60, the arc-shaped surface of the soil supporting cover 100 is protruded upwards, namely the open cavity of the soil supporting cover 100 faces downwards, and the soil supporting cover 100 is fixed on the frame 10; the earth-supporting shroud 100 serves to prevent the trencher 60 from throwing soil outside the trench while rotating;
the lower end of the fertilizer leaking pipe 110 penetrates through the thickness of the soil supporting cover 100.
Furthermore, the radian of the fertilizer applicator 130 corresponding to the opening of the fertilizer containing cavity 131 is at least less than 180 degrees.
Further, the axial length of the semi-cylindrical plate 61 is 10-35cm, and the radius of the semi-cylindrical plate 61 is 10-15 cm.
Further, the axis of the trencher 60 is spaced from the ground a distance 1/7-2/7 of the radius of the semi-cylindrical plate 61.
The present application includes at least the following advantages:
because the rotatable ditcher 60 is arranged at the lower side of the frame 10 and the fertilizer leaking pipe 110 is arranged above the ditcher 60, the ditcher 60 can be conveyed to the position near the corn seedlings by moving a vehicle, the ditcher 60 is controlled to dig the ditches in a rotating mode, meanwhile, the fertilizer leaking pipe 110 leaks the fertilizer and rolls into the ditches, the accurate fertilization of the single corn is realized, and the ditching and the fertilization of the single corn are simultaneously performed efficiently.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
