一种湿烂田压沟宽幅播种机
By using left and right rotary tillers to cover the soil in a wide-width seeder with furrows in wet fields, and combining this with outer and inner shovels to remove soil, the problems of high seed exposure and inconsistent sowing depth in wet fields have been solved. This has resulted in consistent sowing depth and uniform soil covering, thus improving the germination rate.

AI Technical Summary
In wet and sludge conditions, existing dual-shaft rotary tillage and fertilization seeders have problems with high seed exposure rate and inability to control seeding depth. In addition, conventional seeders have difficulty opening furrows and covering soil in wet and sludge conditions.
Using left and right rotary tillers, the soil is tilled and covered on the left and right sides of the furrow, respectively. The outer and inner shovels are used to remove the adhering soil, ensuring consistent sowing depth and uniform soil coverage.
It achieves consistent sowing depth and uniform soil covering under wet conditions, reducing the rate of exposed seeds and increasing the germination rate.

Abstract
Claims
1. A wide-row seeder for wet and rotten fields, comprising a frame, the frame including a left side plate, a right side plate, and a support frame with one end fixedly connected to the left side plate and the other end fixedly connected to the right side plate, characterized in that, The left end of the ditching roller is rotatably connected to the left side plate, and the right end is rotatably connected to the right side plate. A dual-output shaft reducer is fixedly installed on the support frame. The front end of the dual-output shaft reducer has an input shaft, the right side has a first output shaft, and the left side has a second output shaft. The right end of the ditching roller is driven to the first output shaft, and the second output shaft is driven to the rotary tillage and covering mechanism installed on the frame. The rotary tillage and covering mechanism is located behind the ditching roller. A seed box is fixedly installed on the frame. The seed discharge port of the seed box is located between the rotary tillage and covering mechanism and the ditching roller. The ditching roller includes a roller body and several ditching sections that are evenly and spaced apart axially on the roller body. The rotary tillage and covering mechanism includes a rotary tillage blade shaft with several sets of rotary tillage blades on the rotary tillage blade shaft. Each set of rotary tillage blades corresponds to one ditching section.
2. The wet field press wheel wide row planter of claim 1 wherein, The two ends of the rotary tiller shaft are rotatably connected to the rotary tiller shaft seats fixed on the left and right sides via bearings. Each set of rotary tillers includes a left rotary tiller and a right rotary tiller. The left rotary tiller is located on the left side of the corresponding furrow, and the right rotary tiller is located on the right side of the corresponding furrow. The left and right rotary tillers are arranged with opposite rotation directions.
3. The wetland furrow width planter of claim 1, wherein, Each pressing groove corresponds to a seed discharge port. The pressing groove is circular, and the roller is cylindrical.
4. The wetland press wheel furrow width planter of claim 1 wherein, One end of the outer ring shovel plate bracket is fixed to the left side plate and the other end is fixed to the right side plate. Its length direction is parallel to the axial direction of the grooving roller. Several outer ring shovel plates are fixedly installed on the outer ring shovel plate bracket. Each outer ring shovel plate corresponds to a grooving part. The width of the outer ring shovel plate is the same as the width of the grooving part. The end of the outer ring shovel plate is fitted with the grooving part with a clearance.
5. The wetland press wheel furrow width planter of claim 1 wherein, One end of the inner ring shovel plate bracket is fixed to the left side plate, and the other end is fixed to the right side plate. Its length direction is parallel to the axial direction of the grooving roller. Several inner ring shovel plates are fixedly installed on the inner ring shovel plate bracket. Each inner ring shovel plate corresponds to a notch formed between the grooving part and the roller body. The width of the inner ring shovel plate is slightly smaller than the width of the corresponding notch. The end of the inner ring shovel plate is fitted with the notch with a clearance.
6. The wet field furrow width planter of claim 5 wherein, The first output shaft is connected to the first drive shaft rotatably mounted on the right side plate via an intermediate connecting shaft. The first output shaft and the intermediate connecting shaft, as well as the intermediate connecting shaft and the first drive shaft, are fixedly connected via Y-type joints. The first drive shaft is connected to the first drive shaft seat fixed on the right side plate via a bearing. The first drive shaft extends to the first extended section on the outside of the right side plate and a first sprocket is fixedly mounted thereon.
7. The wet field furrow width planter of claim 6 wherein, A second drive shaft seat is fixedly installed on the right side plate. A second drive shaft is rotatably mounted on the second drive shaft seat via bearings.
