The technical solution of the present invention will be further described below in conjunction with the drawings of the embodiments of the present invention, and the present invention is not limited to the following specific implementation methods.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0020] In a specific embodiment of the present invention, there is a moisture conservation seeder, a ridger can open ridges, and the moisture conservation seeder can be driven by the ridger to sow on the ridges while covering with film to conserve moisture, comprising: A frame 1 and a furrowing roller 2, a sowing mechanism 3, a soil covering and moisture conservation roller 4, and a film covering mechanism 5 are sequentially arranged on the frame 1. The furrowing roller 2 can be rotatably mounted on the frame 1. The furrowing roller 2 can adjust its position up and down along the frame 1. The furrowing roller 2 is provided with a furrowing protrusion 21. The furrowing roller 2 can drive the furrowing protrusion 21 to roll and compact the ridge and form a cavity A for seeding. The seeder The mechanism 3 can sow in the seeding cavity A, the soil covering and moisture conservation roller 4 can be rotatably mounted on the frame 1, and the soil covering and moisture conservation member 41 is provided on the soil covering and moisture conservation roller 4. The soil covering and moisture conservation roller 4 drives the soil covering and moisture conservation member 41 to rotate to cover the soil in the seeding cavity A and compact it, and form a moisture conservation ridge C. The film covering mechanism 5 can cover the moisture conservation ridge C with a film, so that the moisture conservation ridge C forms a moisture conservation cavity through the film covering.

[0021] In a specific embodiment, the moisture conservation seeder can drive the ditching protrusion 21 through the ditching roller 2 to initially compact and press out the seeding cavity A and the virtual ridge B on the ridge, and can drive the soil covering and moisture conservation roller 4 to rotate the soil covering and moisture conservation member 41 to cover and compact the seeding cavity A and form a moisture conservation ridge C, and finally the film covering mechanism 5 can cover the moisture conservation ridge C with a film, so that the moisture conservation ridge C forms a moisture conservation cavity through the film covering. The moisture conservation cavity can better make the moisture in the soil hang on the film on the top of the moisture conservation cavity after evaporation, so that the moisture does not lose, and the moisture conservation cavity can serve as a thermal insulation layer between the film and the soil, so as to achieve the effect of heat preservation in cold weather and heat insulation in hot weather.

[0022] In another specific embodiment, the longitudinal position of the adjusting mounting frame 24 on the frame 1 can be controlled by the adjusting mechanism. When the seeding cavity A and the virtual ridge B are initially compacted and pressed out on the ridge, the amount of soil buried above the seeds can be adjusted by adjusting the longitudinal position of the furrowing roller 2 to adapt to the different soil burial depths required for various seeds.

[0023] The trenching protrusion 21 can be a protrusion of any shape that can be rotated to press out the seeding cavity A, and the soil covering and moisture conservation member 41 can press out any moisture conservation ridge C with a top parallel to the film covering top.

[0024] Furthermore, the trenching protrusion 21 includes a cylindrical base 22 and a trenching protrusion ring 23, and the trenching protrusion ring 23 is sleeved on the cylindrical base 22. The cylindrical base 22 can preliminarily compact the ridge, and there is a certain gap between the cylindrical bases 22, which can press out the virtual ridge B with a rectangular cross section on the ridge, providing a prerequisite for the next step of the soil covering and moisture conservation member 41.

[0025] Furthermore, at least one trenching convex ring 23 is installed on the cylindrical base 22. When the cylindrical base 22 preliminarily compacts the ridge and presses out the virtual ridge B, the trenching convex ring 23 can press out the seeding cavity A between the virtual ridges B on the basis of the preliminarily compacted ridge.

[0026] Furthermore, the ditching convex ring 23 is arranged at a position close to the edge of the cylindrical base 22, so that the seeding cavity A is close to the virtual ridge B. When the virtual ridge B and its accessories are squeezed, the soil of the virtual ridge B and its accessories will collapse into the seeding cavity A, thereby achieving the effect that the initially compacted ridge is squeezed to backfill the seeding cavity A well, so that the seeds sown by the sowing mechanism 3 can be buried under the soil collapsed into the soil seeding cavity A, avoiding the problem that the seeds cannot be well buried in the soil after the initially compacted ridge is suppressed, thereby exposing the seeds to the surface.

[0027] Furthermore, there are a plurality of groove opening protrusions 21, and a first gap a is reserved between two adjacent groove opening protrusions 21, and the first gap a can press out virtual ridges B on both sides of the seeding cavity A. The virtual ridges B provide the necessary pre-material basis for the subsequent soil covering and moisture conservation member 41 to press out the moisture conservation ridges C.

[0028] Furthermore, the soil-covering and moisture-retaining member 41 is cylindrical. The cylindrical soil-covering and moisture-retaining member 41 can apply uniform pressure to the soil surface near the seeding cavity A when the moisture-retaining seeder performs soil-covering and moisture-retaining operations, and the presence of the seeding cavity A causes the pressure on the soil near the seeding cavity A to collapse into the seeding cavity A under the mutual squeezing of the soil, thereby achieving an excellent soil backfilling effect and a better moisture-retaining effect for seeds.

[0029] Furthermore, the soil-covering and moisture-retaining roller 4′ is provided with a plurality of soil-covering and moisture-retaining members 41, and a second gap b is reserved between two soil-covering and moisture-retaining members 41. The soil-covering and moisture-retaining members 41 can use the second gap b to press the virtual ridge B′ into the moisture-retaining ridge C by rolling and rotating. The soil-covering and moisture-retaining roller 4′ is lower than the top of the virtual ridge B′, so the second gap b can press the relatively loose virtual ridge B′ into the more compact moisture-retaining ridge C, and between the moisture-retaining ridges C is soil compacted by the cylindrical soil-covering and moisture-retaining members 41.

[0030] In a further embodiment, there are a plurality of sowing mechanisms 3, and the distribution positions of the plurality of sowing mechanisms 3 are aligned with the furrowing convex ring 23, and the sowing mechanisms 3 can sow in the sowing cavity A. The sowing mechanism 3 can be any intermittent sowing mechanism 3 such as an automatically rotating duckbill seeder, a direct insertion seeder, and a hole seeder.

[0031] Further, the sowing mechanism 3 includes a seed guide plate 31, which is arranged on both sides of the lower end of the sowing mechanism 3 and can discharge the seeds sown by the sowing mechanism 3 into the sowing cavity A. The seed guide plate 31 can block the deviated seeds back to the sowing cavity A when the initial speed direction of the seeds deviates from the sowing cavity A when sowing from the sowing mechanism 3. The seed guide plate 31 can also block the seeds that bounce up after being sown into the sowing cavity A and then return them to the sowing cavity A.

[0032] Further, such as Figure 5 As shown, the soil moisture conservation seeder further includes a scraper 6, which is arranged on one side of the furrowing roller 2 and is used to remove the soil on the outer surface of the furrowing roller 2 and the furrowing protrusion 21. The scraper 6 is preferably arranged between the furrowing roller 2 and the soil-covering and moisture conservation roller 4, and the shape of the scraping part of the scraper 6 is preferably an equidistant shape of the cross-section of the furrowing roller 2 and the furrowing protrusion 21 installed on the furrowing roller 2. The scraper 6 removes the soil carried on the outer surface of the furrowing roller 2 and the furrowing protrusion 21 when the ridge is initially compacted, so as to prevent the soil from falling in front of the movement of the furrowing protrusion 21, thereby affecting the compaction of the soil during the subsequent furrowing operation.

[0033] Furthermore, a longitudinal adjustment mounting frame 24 is provided between the grooving roller 2 and the frame 1, and the adjustment mounting frame 24 is connected to the frame 1 through an adjustment mechanism. The adjustment mechanism can make the longitudinal adjustment mounting frame 24 move longitudinally relative to the frame 1, and the grooving roller 2 can be rotatably mounted on the adjustment mounting frame 24.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
