DETAILED DESCRIPTION
[0018] The utility model will be further described in connection with the drawings and specific embodiment:
[0019] Specific embodiment such as Figures 1-4 As shown in the figure, a front seedbed compression seeding machine, including frame 1, key, still including by the ditching unit 2, front compression unit 3, seeding unit 4 and covering unit 5 that are sequentially arranged on frame 1 from first to rear along working order, the ditching unit 2 forms first groove 6 on plot, the front compression unit 3 and first groove 6 form compression cooperation, the seed outlet end of seeding unit 4 is located above first groove 6, and the ditching unit 2 is ditching shovel.
[0020] In operation, the first trench 6 is formed on the ploughed field by the trenching unit 2, and then the surface of the first trench 6 is compacted by the front compacting unit 3, which only compacts the soil in the first trench 6, so that the soil under the seedbed is formed into a compacted soil structure, preventing the seed from being in a "vacant" state, and enabling the moisture in the soil under the first trench 6 to rise along the capillary, promoting the crop emergence and seedling root growth.
[0021] Further, the front compacting unit 3 comprises a compacting shaft 7, a set of convex rings 8 arranged on the compacting shaft 7, and a pressure pit protrusion 14 arranged on the convex ring 8, the convex ring 8 is in compacting cooperation with the bottom of the first trench 6, and the pressure pit protrusion 14 rolls on the bottom of the first trench 6 to form a front compacting trench 9, the width of the front compacting trench 9 is smaller than that of the first trench 6, and the seed outlet end of the seeding unit 4 is arranged in cooperation with the front compacting trench 9. The compacting shaft 7 is higher than the height of the soil raised by the first trench 6. Specifically, the seed outlet end of the seeding unit 4 is located above the front compacting trench 9
[0022] The upper layer of dry soil is first pushed to both sides by the trenching unit 2 to form the first trench 6 on the field, and then the front compacting unit 3 passes through the first trench 6, the convex ring 8 compacts the soil at the bottom of the first trench 6, and the pressure pit protrusion 14 extrudes and slides on the soil at the bottom of the first trench 6 to form the front compacting trench 9 for receiving seeds, which is located in the wet soil layer, being beneficial to the growth of seeds; the soil at the bottom of the first trench 6 is compacted, improving the continuity of the capillary in the soil under the seeds, and ensuring the depth of the front compacting trench 9, i.e. the uniformity of the sowing depth, the seeds are sown into the front compacting trench 9 by the seeding unit 4 to make the seeds contact with the wet soil in the compacting chamber, preventing the seeds from being "vacant". The trenching is sequentially performed by the trenching unit 2 and the front compacting unit 3, reducing the resistance of trenching, and separating the dry soil from the wet soil generated by the trenching, the dry soil raised by the first trench 6 is backfilled by the covering unit 5 after sowing, reducing the wet soil contained in the soil backfilled above the seeds, ensuring that the soil backfilled above the seeds is the loose and fine soil after ploughing, forming a loose soil layer above the seeds, destroying the capillary structure on the surface of the soil, weakening the evaporation speed of the water on the surface of the soil, effectively reducing the evaporation amount of the soil, increasing the permeability and water retention of the soil, and providing a better growing environment for crops.
[0023] Further, the cross section of the pressure pit protrusion 14 is triangular, and the corner of the pressure pit protrusion 14 slides on the bottom of the first trench 6, facilitating the formation of the front compacting trench 9.

The seed metering device 11 is a mature product in the market.
[0025] The earthing unit 5 is a pair of earthing blades arranged on the frame 1, which is used to scrape the raised soil after the trenching unit 2 to make the soil fall into the first groove 6 and the front pressing groove 9, and complete the backfilling.
[0026] The frame 1 is also provided with a rear pressing roller 13 arranged behind the earthing unit 5, which is used to press the soil according to the soil condition. The rear pressing roller 13 and the earthing unit 5 form an earthing and pressing unit.
