Embodiment a soil sealing compaction device for seeder

The embodiment discloses a soil sealing compaction device for a seeder, as shown in fig. 1 and fig. 2, the soil sealing compaction device comprises a frame 1, a seeding box 2, a rolling crushing mechanism, a soil sealing mechanism and a press roller 15, wherein the seeding box 2, the rolling crushing mechanism, the soil sealing mechanism and the press roller 15 are sequentially arranged along the opposite direction of the movement direction of the seeder (namely the opposite direction of the seeding operation), the seeding box 2 is installed on the frame 1, the rolling crushing mechanism and the soil sealing mechanism are installed on the frame 1 through a first adjusting frame 3, the first adjusting frame 3 is pivoted on the frame 1 and close to one end of the seeding box 2, the first adjusting frame 3 is located below the frame 1, and the rolling crushing mechanism and the soil sealing mechanism are respectively installed at one end of the first adjusting frame 3, which is far away from the pivoting shaft of the first adjusting frame 3. The press roller 15 is installed on the second adjusting frame 14, and the second adjusting frame 14 is pivoted at one end position of the first adjusting frame 3 far away from the sowing box 2. The working principle of the embodiment is as follows: the rolling and crushing mechanism crushes soil blocks with larger volume on one hand, and prepresses the sowed soil on the other hand, and the rolling and crushing mechanism and the soil sealing mechanism are both arranged on a first adjusting frame 3 pivoted with the rack 1, and the adjustment of the rolling and crushing mechanism and the soil sealing mechanism is realized by adjusting the opening and closing angle of the first adjusting frame 3, so that the rolling and crushing mechanism and the soil sealing mechanism adapt to the soil with different gradients and different soft conditions, and the soil blocks are fully crushed and the sowed grooves are fully buried; second alignment jig 14 and the pin joint of first alignment jig 3, the compression roller 15 is installed on second alignment jig 14, and through adjusting second alignment jig 14 and realize the height of compression roller 15 to realize the compaction of the planting soil of different soil property.

The rolling and crushing mechanism in this embodiment is preferably configured such that, as shown in fig. 1, the rolling and crushing mechanism includes disks 4 oppositely disposed on two sides of the first adjusting frame 3, each disk 4 is rotatably connected to a corresponding side of the first adjusting frame 3, a plurality of rod bodies 5 are uniformly and fixedly mounted between the two disks 4 along the circumferential direction of the disks 4, and two axial ends of each rod body 5 are respectively welded to the two disks 4. Soil blocks with larger volume enter the cylindrical structure formed by the two discs 4 and the rod bodies 5 through the gap between the two adjacent rod bodies 5, the crushing is realized through the ceaseless rotation of the cylindrical structure, and the cylindrical structure pre-rolls the soil so as to facilitate the subsequent burying operation. The rotation mode of the cylindrical structure is two, the first one is driven to rotate, namely, the cylindrical structure is contacted with the ground along with the movement of the seeder and rotates under the action of friction force; the second type is active rotation, namely a driving motor 6 is arranged on the first adjusting frame 3, an output shaft of the driving motor 6 is coaxially connected with one of the two discs 4, and the driving motor 6 drives the cylindrical structure to rotate; compared with the second mode, the second mode is superior to the first mode, and mainly the first mode often has the condition that the tubular structure slips, and can not keep rotating all the time to realize smashing clods, and the tubular structure slips and can damage the sowed groove, so that the seed is separated from the groove. And in order to realize that harder bulky clods smoothly get into tubular structure, the body of rod 5 chooses for use the material that has certain deformation, the preferred hard wire rope that is. In order to enhance the strength of the rod 5 and avoid deformation, a support ring is fixedly installed at the middle position of the cylindrical structure formed by the two disks 4 and the rod 5, and the support ring is used for supporting the rod 5.
