The overall frame is composed of a wheel (20), a wheel motor (25), an upper bottom plate (5), a lower bottom plate (21) and a support column (16), the plowshare (1) is installed at the front end of the frame, and the plowshare structure is driven by a connecting rod (2) device to move up and down. The motor (22) is connected to the driving shaft (15) through a coupling (23) to drive the active dial (14) to rotate. The storage bin (7), the feeding groove wheel (8), the feeding screen plate (9), and the feeding shaft (24) realize the feeding function, and the fertilizer storage bin (10), the fertilizer groove wheel (12), the fertilizer screen plate (13), and the fertilizer shaft (19) complete the fertilization work. The covering plate (18) and the support plate (17) fill the soil turned over by the plowshare back into the farm ditch.

[0025] In order to adjust the height of the furrowing plowshare to meet different working requirements, a crank slider mechanism is adopted. The plowshare (1) is loaded on a connecting rod (2) and driven by a steering gear. When the connecting rod (2) rotates, the slider (3) is driven to perform linear motion on a linear guide rail (4).

[0026] In order to realize the functions of feeding and fertilizing, a double groove wheel structure is used. A cylindrical pin is arranged on the active dial (14), and when rotating, the cylindrical pin is driven to mesh with the feeding groove wheel (8) and the fertilizing groove wheel (12) in turn, so that the groove wheels rotate.
