DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings:

[0017] like Figures 1 to 3The corn-soybean composite planter shown includes a frame 1 provided with a traction frame 11, a gearbox, a rotary tillage device 2 and a sowing device 3. The rotary tillage device 2 includes a rotary tillage shaft and a rotary tillage blade. The rotary tillage blade is provided on the rotary tillage shaft. The traction frame 11 is provided above the frame 1. The rotary tillage device 2 is installed at the lower front part of the frame 1 and is connected to the gearbox. The traction frame 11 is used to be connected to the tractor. The tractor is connected to the gearbox through the power output shaft. The gearbox drives the rotary tillage shaft to rotate and drives the rotary tillage blade to operate. The sowing device 3 is installed in the lower middle part of the frame 1. A soil covering device is installed at the lower rear part of the frame 1. The soil covering device includes two soil covering plates 4 that are wide inside and narrow outside, narrow at the bottom and wide at the top. The sowing device 3 includes a storage box 31, a seed meter 32, a seed metering tube 33 and a furrow opener 34. The storage box 31 is connected to the seed meter 32, and the seed meter 32 is connected to the seed metering tube 33. A crossbeam 5 is provided at the lower rear part of the frame 1, and the crossbeam 5 is provided with a support 51. The front part of the support 51 is connected to the furrow opener 34, and the middle part of the support 51 is connected to the lower part of the seed metering tube 33. The furrow opener 34 is used to dig furrows in the field to form field furrows. Corn or soybean seeds flow into the seed meter 32 through the storage box 31, and the seed meter 32 drops the seeds one by one along the seed metering tube 33 into the field furrow, and then covers the seeds with the raised soil on both sides of the field furrow through two covering plates 4. The two covering plates 4 are connected to one end of the bracket 6, and the other end of the bracket 6 is hinged to the tail of the support 51, so that the bracket 6 can float up and down. A limit rod 52 is provided below the tail of the support 51, and a connecting plate 61 is provided in the middle of the bracket 6. A torsion spring 7 is provided between the support 51 and the bracket 6. The torsion foot of the torsion spring 7 is pressed on the support 51, and the torsion arm 71 of the torsion spring 7 is pressed on the connecting plate 61 so that the bottom of the bracket 6 is tightly pressed against the limit rod 52. When walking and rotary tilling and sowing, when the covering plate 4 encounters harder soil, it will be lifted up. After walking, the covering plate 4 will be pressed back to its original position by the torsion spring 7. The cover plate 4 is provided with a cylinder 41 having a through-hole at its head end. The bracket 6 is provided with a circular tube 62 having a ring 42 at its head end. The cylinder 41 is inserted into the tube 62, with the through-hole of the cylinder 41 passing through the ring 42. A cotter pin 43 is inserted into the through-hole of the cylinder 41. The cover plate 4 is shaped like an arc-shaped circular plate. The diameter of the cylinder 41 is smaller than the inner diameter of the tube 62, while the outer diameter of the ring 42 is larger than the outer diameter of the tube 62. The inner diameter of the ring 42 is larger than the diameter of the cylinder 41 but smaller than the inner diameter of the tube 62. This provides a relatively loose connection between the cover plate 4 and the bracket 6, preventing deformation and damage caused by long-term contact with hard objects. The support 51 is provided with a fixing sleeve, into which the seed pipe 33 is inserted. Scraper plates 12 are provided on both sides of the frame 1.
