Description

Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to a sowing unit which uses a plastic pressing structure to complete the processing of a seed bed and a seed groove before sowing operation. Background Art

[0002] A good quality seedbed seed ditch can provide important basic conditions and guarantees for the germination of crop seeds, root development and crop growth. At present, the seedbed seed ditch processing is mostly completed by a single disc or double disc seedbed seed ditch opener. In many years of production and operation practice, it is found that since the single disc or double disc opener uses a rolling and cutting operation method to form a ditch, the quality of the constructed seedbed seed ditch and the operation effect cannot adapt to and meet the high-level sowing agronomic technical operation requirements. There are many technical defects such as loose and loose soil in the seedbed seed ditch, easy collapse of the soil in the seedbed seed ditch, irregular shape of the seedbed seed ditch, etc., resulting in the seeds after sowing not being able to fully contact with the soil in the seedbed seed ditch, the phenomenon of air leakage due to poor sealing of seeds, and low temperature of the soil in the seedbed seed ditch. At the same time, the loose soil in the seedbed seed ditch affects the siphoning capacity of the soil, reduces the water content of the soil in the seedbed seed ditch, and is not conducive to seed rooting and root growth. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, and in combination with the current actual needs for the construction of seed beds and seed trenches, to study and design a seed bed and seed trench synchronous plastic pressing sowing unit, so as to achieve the purpose of constructing a seed bed and seed trench with compact soil and regular shape, which is conducive to seed germination and plant growth.

[0004] The purpose of the invention is achieved in this way: a Π-shaped frame is hung and installed on the front end of the single frame and located below the single parallel four-bar profiling mechanism through a seed bed seed groove plastic pressing parallel four-bar profiling mechanism; a main shaft is rotatably supported and installed on the vertical wall plates on both sides of the Π-shaped frame through a bearing seat assembly; a conical disc-shaped seed groove plastic pressing wheel is fixedly installed on the main shaft at the middle part of the inner side of the vertical wall plates on both sides of the Π-shaped frame; grooved cylindrical seed bed plastic pressing rollers are symmetrically and rotatably mounted on the main shaft and located on both sides of the conical disc-shaped seed groove plastic pressing wheel; seat plates are relatively rotatably mounted on the main shaft and located between the vertical wall plates on both sides of the Π-shaped frame and the opposite grooved cylindrical seed bed plastic pressing rollers; the seat plate is fixedly connected to the Π-shaped frame through a fastener group; and a grooved cylindrical seed bed plastic pressing roller is mounted on the main shaft and located on both sides of the conical disc-shaped seed groove plastic pressing wheel. A gear shaft support plate is relatively rotatably mounted inside the groove cavity, and gear shaft I and gear shaft II are respectively supported and inserted in parallel on the relatively arranged seat plate and gear shaft support plate, and cylindrical gear I and cylindrical gear II are respectively rotatably mounted on gear shaft I and gear shaft II, and an inner gear ring is fixed on the circumferential inner wall surface of the grooved cylindrical seed bed plastic pressing roller, and cylindrical gear III is fixed on the main shaft, and the cylindrical gear I is respectively meshed with the inner gear ring and cylindrical gear II, and the cylindrical gear III is meshed with cylindrical gear II; the transmission ratio of the cylindrical gear I and the cylindrical gear III is a speed increase ratio; the diameter size of the conical disc-shaped seed groove plastic pressing wheel is larger than the diameter size of the grooved cylindrical seed bed plastic pressing roller; a transverse anti-skid pressing boss is provided on the circumferential outer wall surface of the grooved cylindrical seed bed plastic pressing roller, thereby constituting a seed bed seed groove synchronous plastic pressing sowing unit.

[0005] The invention has a novel, unique and reasonable structure. The seed bed and seed ditch structure constructed by combining rolling and extrusion greatly improves the compactness of the seed bed and seed ditch soil. The shape is standardized and neat, the bed wall and ditch wall soil do not collapse, the seed bed and seed ditch soil temperature and moisture content are high, the seeds are in close and full contact with the seed ditch soil, thereby ensuring and promoting the seed germination rate and the quality of plant growth.

[0017] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. A seed bed seed groove synchronous plastic pressing sowing unit, comprising a unit frame 1, a unit parallel four-bar profiling mechanism 2 and a fixed seed box 15 and a fertilizer box 14 are hingedly installed on the front end and upper end of the unit frame 1, a seed meter 13, a ground wheel 11 and a soil covering and pressing wheel 12 are sequentially installed on the lower side of the unit frame 1, a Π-shaped frame 4 is suspended and installed at the front end of the unit frame 1, located below the unit parallel four-bar profiling mechanism 2, through a parallel four-bar profiling mechanism 3 for plastic pressing of the seed bed seed groove, and on the opposite sides of the Π-shaped frame 4 The main shaft 7 is rotatably supported and installed on the vertical wall plate through the bearing seat assembly 6. The conical disc-shaped seed groove plastic pressing wheel 10 is fixedly installed on the main shaft 7 at the middle part of the inner side of the vertical wall plates on both sides of the Π-shaped frame 4. On the main shaft 7, at the positions on both sides of the conical disc-shaped seed groove plastic pressing wheel 10, grooved cylindrical seed bed plastic pressing rollers 9 are symmetrically and rotatably mounted respectively. On the main shaft 7, at the positions between the vertical wall plates on both sides of the Π-shaped frame 4 and the opposite grooved cylindrical seed bed plastic pressing rollers 9, respectively, the grooved cylindrical seed bed plastic pressing rollers 9 are symmetrically and rotatably mounted respectively. A seat plate 8 is mounted, and the seat plate 8 is fixedly connected to the Π-shaped frame 4 through a fastener group 5. A gear shaft support plate 22 is relatively rotatably mounted on the main shaft 7 at the inner position of the groove cavity of the groove-shaped cylindrical seed bed plastic pressing roller 9. The seat plate 8 and the gear shaft support plate 22 are relatively configured to support the insertion gear shaft I18 and the gear shaft II20 in parallel with each other. The cylindrical gear I17 and the cylindrical gear II19 are rotatably mounted on the gear shaft I18 and the gear shaft II20 respectively. An inner gear ring 16 is fixed on the inner wall surface, and a cylindrical gear III21 is fixed on the main shaft 7. The cylindrical gear I17 is meshed with the inner gear ring 16 and the cylindrical gear II19 respectively, and the cylindrical gear III21 is meshed with the cylindrical gear II19; the transmission ratio of the cylindrical gear I17 and the cylindrical gear III21 is a speed-up ratio; the diameter of the conical disc-shaped seed groove plastic pressing wheel 10 is larger than the diameter of the grooved cylindrical seed bed plastic pressing roller 9; a transverse anti-skid pressing boss is provided on the outer wall surface of the circumference of the grooved cylindrical seed bed plastic pressing roller 9.

[0018] When in use, the single parallel four-bar profiling mechanism 2 is used to suspend the sowing unit as a whole on the frame of the sowing operation tool and move forward. Under the friction resistance of the outer circumferential surface of the grooved cylindrical seed bed plastic pressing roller 9 in close contact with the field soil, the grooved cylindrical seed bed plastic pressing roller 9 drives the inner gear ring 16 fixed thereon to rotate on the main shaft 7. While the grooved cylindrical seed bed plastic pressing roller 9 performs and completes the soil pressing operation at the seed bed, the rotating inner gear ring 16 drives the main shaft 7 to rotate via the cylindrical gear I 17, the cylindrical gear II 19, and the cylindrical gear III 21 in sequence. The rotating main shaft 7 drives the conical disc-shaped seed groove plastic pressing wheel 10 to make contact with the grooved cylindrical seed bed plastic pressing roller 9. The cylindrical seed bed plastic pressing roller 9 rotates in the same direction, and the conical disc-shaped seed groove plastic pressing wheel 10 with a diameter larger than that of the grooved cylindrical seed bed plastic pressing roller 9 presses a triangular seed groove in the middle part of the seed bed. Based on the transmission ratio between the cylindrical gear Ⅰ17 and the cylindrical gear Ⅲ21 being the speed-up ratio, the conical disc-shaped seed groove plastic pressing wheel 10 with a faster rotation speed and linear speed produces a relative translational sliding and smearing effect on the side wall and bottom wall of the seed groove, which not only makes the soil in the seed groove tighter and firmer, but also makes the shape of the seed groove more precise. Afterwards, after the seed meter 13 completes sowing in the seed groove, the soil covering pressing wheel 12 carries out and completes the compaction and sealing processing of the seed bed and the covering soil layer above the seed groove.
