Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1 to 3, in the present embodiment, the soybean seeder includes a frame 4, the frame 4 has a front end connected to a power tractor such as a tractor, a furrowing device and a seeding device are sequentially disposed on the frame 4 from front to back, and in the process of advancing, the soybean seeder firstly forms a groove on each field area through the furrowing device, and then seeds are sown in the groove through the seeding device.

In this embodiment, the ditching device comprises a plurality of first ditching cutters 7 which are transversely arranged, distributed and fixedly installed on the rack 4; the seeder includes seed case 2, pinch roller 1 and seed metering ware (not shown in the figure), seed case 2 and pinch roller 1 all have a plurality ofly and with 7 quantity of first ditching swoves are the same, pinch roller 1 rotates and installs in frame 4, and the seed metering ware is with the seed blanking in seed case 2 in proper order and arrange in the slot, and then realize the seeding. Preferably, the sowing machine further comprises a plurality of second ditching knives 3 fixedly mounted on the machine frame 4, the second ditching knives 3 are positioned between the pressing wheel 1 and the first ditching knife 7, secondary ditching can be carried out on the grooves before sowing through the arrangement of the second ditching knives 3, the sowing device and the ditching device are improved on the basis of the prior art, the sowing device and the ditching device are the same as the Chinese patent application with the publication number of CN111788889A, and the ditching and sowing processes of the sowing machine can be better understood after the prior art patent application documents are read.

The improved part of the invention is that the invention also comprises a ditching device arranged at one lateral side of the frame 4 and used for ditching the trench between the field areas and a rotary pushing device arranged between the ditching device and the seeding device and used for leveling soil piled after ditching the trench towards the inner side of the field areas.

The rotary pushing device comprises a rotating shaft 9 rotatably installed on the rack 4 and a spiral plate 6 fixedly installed on the rotating shaft 9, the rotating shaft 9 is in transmission connection with a power device 5, the power device 5 is installed on the rack 4, the spiral radius of the spiral plate 6 is gradually reduced from one side of the grooving device to the other side, in other words, the height of the spiral plate 6 close to one side of the grooving device from the ground is maximum, the height of the spiral plate 6 far from one side of the grooving device from the ground is minimum, therefore, when the grooving device conducts trench digging, accumulated soil is pushed to the other side along with the rotation of the spiral plate 6, and the soil leveling effect is achieved.

Referring to fig. 2 again, the trenching device comprises a trenching shovel 10 and a plowshare 8, the trenching shovel 10 is rotatably mounted on the frame 4 and located behind the rotary pushing device, the plowshare 8 is longitudinally slidably arranged on the frame 4 and located in front of the rotary pushing device, the plowshare 8 is driven to longitudinally move by a jacking cylinder 11 fixedly mounted on the frame 4, so as to adjust the distance between the plowshare 8 and the ground, in addition, the top of the trenching shovel 10 is hinged to a connecting rod 12, the other end of the connecting rod 12 is hinged to the top of the plowshare 8, and in the process that the plowshare 8 longitudinally slides, the trenching shovel 10 is pulled by the connecting rod 12 to rotate around a connecting shaft of the trenching shovel, so that the trenching shovel 10 and the plowshare 8 synchronously lift or fall. In the advancing process of the soybean seeder, the plowshare 8 firstly turns over the trench to loosen the soil, then the ditching shovel 10 pushes the loosened field to shovel and form the trench, the soil accumulated on the ditching shovel 10 is pushed to the other side along with the rotation of the spiral plate 6, and then the soil leveling effect is achieved, so that the integrated operation of sowing and trench opening is realized.
