Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery, and in particular relates to a spot-planting no-till seeder. Background Technology

[0002] Conservation tillage is an advanced agricultural technique that reduces field operations, mitigates soil erosion by wind and water, improves topsoil structure, and increases crop yields. It includes no-till and reduced tillage. No-till involves direct seeding under conditions where the surface is covered with straw and crop stubble is present underground. Current no-till seeders are used for ridge tillage, also known as ridge cultivation, which involves artificially creating raised, ridge-like structures on a level surface.

[0003] Point-planting no-till technology refers to loosening the soil, applying fertilizer, and sowing at the designated planting points in the field. This further reduces fieldwork compared to existing ridge-planting no-till technology. It also allows for precise fertilization and sowing. Existing point-planting seeders sometimes cause some of the drilled soil to flow back into the holes, requiring deeper drilling to meet planting depth requirements. Furthermore, existing seeders typically perform soil filling and fertilization in a single operation, unable to perform multiple fillings and fertilizations, and still require manual operation, resulting in high labor intensity. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a spot-planting no-till seeder. The seeder has a drilling mechanism with anti-backfilling function, which can prevent the soil drilled out from falling back into the hole when the drill bit is pulled out of the hole. At the same time, the seeder also has a soil filling mechanism and a fertilization mechanism that can fill soil multiple times, which improves the scope of use of the seeder and eliminates the need for manual labor.

[0005] Specifically, this invention discloses a spot-planting no-till seeder, including a vehicle body, characterized in that it further includes:

[0006] A drilling mechanism is connected to the vehicle body and to the fertilization mechanism. The drilling mechanism includes a base and a drill bit. The drill bit is connected to the base, and the base and / or the drill bit can move up and down.

[0007] A backfilling mechanism for filling the holes drilled by the drill bit;

[0008] Fertilization facilities, sowing facilities, and irrigation facilities.

[0009] By adopting the above scheme, the liftable base and the liftable drill bit work together to drill holes in the land. Then, the fertilization mechanism, the sowing mechanism, the soil filling mechanism, and the irrigation mechanism carry out the first fertilization, the first soil filling, the sowing, the second fertilization, the second soil filling, and the irrigation.

[0010] Furthermore, the drilling mechanism also includes an anti-backfilling mechanism.

[0011] Furthermore, the anti-backfilling mechanism includes an elastic damper and an anti-backfilling frustum. The top of the elastic damper is connected to the base, and the bottom is connected to the anti-backfilling frustum. A through hole matching the drill bit is opened in the center of the anti-backfilling frustum.

[0012] By adopting the above scheme, the elastic damping makes the anti-backfilling truncated cone abut against the bottom surface, avoiding excessive pressure on the ground from the anti-backfilling truncated cone, which could damage the mechanism and the bottom surface. The drilled soil slides down the slope of the anti-backfilling truncated cone and is blocked by the anti-backfilling truncated cone, so it will not flow back into the hole.

[0013] Furthermore, the soil filling mechanism includes a first soil filling mechanism and a second soil filling mechanism. The first soil filling mechanism is located between the fertilization mechanism and the sowing mechanism, and the second soil filling mechanism is located at one end of the seeder.

[0014] By adopting the above scheme, multiple sets of filling mechanisms can carry out multiple filling operations to meet different filling needs and usage scenarios.

[0015] Furthermore, both the first and second filling mechanisms include an installation plate, a lifting plate, a lifting and rotating part, a soil scraper, a rotating shaft, a slide rail, and a guide shaft. The lifting plate is disposed in the installation plate, and a guide groove is provided at the bottom of the lifting plate. The lifting and rotating part is installed on the installation plate, and the rotating shaft is connected to the lifting and rotating part. A slider is connected to the bottom of the rotating shaft. The soil scraper is fixedly connected to the slide rail, and one end of the guide shaft is fixedly connected to the slide rail, while the other end is slidably connected to the guide groove.

[0016] Furthermore, the outline of the guide groove is an Archimedean spiral.

[0017] By adopting the above scheme, the lifting and rotating part drives the lifting plate and the rotating shaft to move up and down, while controlling the rotation of the rotating shaft. The rotating shaft drives the slider, and the slide rail moves in the slider, causing the guide shaft and the soil scraper to rotate along the guide groove. The soil scraper gathers the soil into a pile and then fills the hole.

[0018] Furthermore, the fertilization mechanism is provided in two sets, namely a first fertilization mechanism and a second fertilization mechanism. The first fertilization mechanism is located between the drilling mechanism and the first filling mechanism and is used to apply base fertilizer. The second fertilization mechanism is located between the sowing mechanism and the second filling mechanism and is used to apply top dressing fertilizer.

[0019] By adopting the above scheme, two sets of fertilization units are used to apply different fertilizers in different processes.

[0020] Furthermore, the sowing mechanism is located between the first soil filling mechanism and the second fertilization mechanism.

[0021] Furthermore, the irrigation mechanism is located on one side of the second backfilling mechanism and includes a water storage tank and a water pipe. The water storage tank is connected to the water pipe, and the water pipe is connected to the rotating shaft through a water trough.

[0022] By adopting the above scheme, water flows along the water channel to the rotating shaft, and then flows downward along the rotating shaft to the soil slab.

[0023] Furthermore, the surface of the soil sheet is provided with an arc-shaped groove for water to flow through.

[0024] By adopting the above scheme, the arc-shaped trough restricts the direction of water flow, preventing water dispersion and affecting irrigation effect. Attached Figure Description

[0033] The reference numerals in the attached drawings are as follows: vehicle body 1, drilling mechanism 2, base 21, drill bit 22, anti-backfill mechanism 23, elastic damping 231, anti-backfill truncated cone 232, fertilization mechanism 3, first fertilization mechanism 31, second fertilization mechanism 32, filling mechanism 4, first filling mechanism 41, lifting and rotating part 411, mounting plate 412, lifting plate 413, guide groove 4131, soil scraper 414, arc groove 4141, slide rail 415, slider 416, rotating shaft 417, guide shaft 418, second filling mechanism 42, sowing mechanism 5, irrigation mechanism 6, water storage tank 61, water pipe 62, water trough 63, connecting plate 7. Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035] like Figure 1-7 As shown, this invention discloses a spot-planting no-till seeder, including a vehicle body 1, characterized in that it further includes:

[0036] Drilling mechanism 2 is connected to vehicle body 1 and fertilizer application mechanism 3. Drilling mechanism 2 includes base 21 and drill bit 22. Drill bit 22 is connected to base 21, and base 21 and / or drill bit 22 move up and down.

[0037] The soil filling mechanism 4 fills the holes drilled by the drill bit 22.

[0038] Fertilization mechanism 3, sowing mechanism 5, irrigation mechanism 6.

[0039] Among them, the fertilization mechanism 3, the sowing mechanism 5, and the irrigation mechanism 6 are all fixedly connected to the vehicle body 1 through the connecting plates 7 on both sides.

[0040] The drilling mechanism 2 also includes an anti-backfilling mechanism 23.

[0041] When both the base 21 and the drill bit 22 can move up and down, the base 21 drives the anti-backfill mechanism 23 to descend, and the drill bit moves up and down in the anti-backfill mechanism 23. When the base 21 moves up and down, the height of the drill bit 33 is lower than the height of the anti-backfill mechanism 23, and the base 21 drives the drill bit and the anti-backfill mechanism 23 to move downward. When the drill bit moves up and down, the drill bit 33 first drives the anti-backfill mechanism 23 to move downward. After contacting the ground, the anti-backfill mechanism 23 stops moving, and then only the drill bit 33 moves downward.

[0042] The anti-backfilling mechanism 23 is connected to the base 21. The anti-backfilling mechanism 23 includes an elastic damper 231 and an anti-backfilling frustum 232. The top of the elastic damper 231 is connected to the base 21, and the bottom is connected to the anti-backfilling frustum 232. The center of the anti-backfilling frustum 232 has a through hole that matches the drill bit 22.

[0043] The lifting and lowering of the drilling mechanism 2 is controlled by a hydraulic cylinder. When the drilling mechanism 2 moves downward, the bottom surface of the anti-backfilling truncated cone 232 contacts the ground, and the elastic damper 231 contracts under force. The anti-backfilling truncated cone 232 can make better contact with the ground, and the drilled soil slides down the slope of the anti-backfilling truncated cone 232 and is blocked by the anti-backfilling truncated cone 232, so it will not flow back into the hole.

[0044] The soil filling mechanism 4 includes a first soil filling mechanism 41 and a second soil filling mechanism 42. The first soil filling mechanism 41 is located between the fertilization mechanism 3 and the sowing mechanism 5, and the second soil filling mechanism 42 is located at one end of the seeder.

[0045] Both the first filling mechanism 41 and the second filling mechanism 42 include a mounting plate 412, a lifting plate 413, a lifting and rotating part 411, a soil scraper 414, a rotating shaft 417, a slide rail 415, and a guide shaft 418. The lifting plate 413 is located in the mounting plate 412, and a guide groove 4131 is provided at the bottom of the lifting plate 413. The lifting and rotating part 411 is mounted on the mounting plate 412. The rotating shaft 417 is connected to the lifting and rotating part 411, and a slider 416 is connected to the bottom of the rotating shaft 417. The soil scraper 414 is fixedly connected to the slide rail 415. One end of the guide shaft 418 is fixedly connected to the slide rail 415, and the other end is slidably connected to the guide groove 4131.

[0046] The lifting and rotating part 411 is existing technology, which can control both the lifting and lowering movement of the lifting plate 413 and the rotation of the rotating shaft 417.

[0047] The outline of the guide groove 4131 is an Archimedean spiral.

[0048] The lifting and rotating part 411 drives the lifting plate 413, the rotating shaft 417, and the soil scraper 414 to move downwards, so that the soil scraper 414 contacts the ground. Then, the lifting and rotating part 411 drives the rotating shaft 417 to rotate, and at the same time drives the soil scraper 414 to rotate, so that the guide shaft 418 slides in the guide groove 4131, and the slide rail 415 moves in the slider 416 below the rotating shaft 417. Since the outline of the guide groove 4131 is an Archimedean spiral, the rotation radius of the soil scraper 414 gradually decreases, gathering the drilled soil and filling the drilled hole with soil.

[0049] The fertilization mechanism 3 has two sets, namely the first fertilization mechanism 31 and the second fertilization mechanism 32. The first fertilization mechanism 31 is located between the drilling mechanism 2 and the first filling mechanism 41 and is used to apply base fertilizer. The second fertilization mechanism 32 is located between the sowing mechanism 5 and the second filling mechanism 42 and is used to apply top fertilizer.

[0050] Fertilizer applicator 3 is used to apply different fertilizers, and the amount of fertilizer applied can be adjusted according to the type of fertilizer. Setting up multiple fertilizer applicators 3 can expand the application scenarios of the seeder, allowing adjustments based on the type of seed. Fertilizer applicator 3 is existing technology and will not be described in detail here.

[0051] The sowing mechanism 5 is installed between the first soil-filling mechanism 41 and the second fertilization mechanism 32. The sowing quantity can be adjusted according to the seed type. Sowing is carried out after applying base fertilizer and covering part of the soil; the base fertilizer provides nutrients to the seeds. The sowing mechanism 5 is also existing technology and will not be described in detail here.

[0052] The irrigation mechanism 6 is located on one side of the second backfilling mechanism 42, and includes a water storage tank 61 and a water pipe 62. The water storage tank 61 is connected to the water pipe 62, and the water pipe 62 is connected to the rotating shaft 417 through a water flow channel 63. The surface of the backfilling sheet 414 is provided with evenly distributed arc-shaped channels 4141 through which water flows.

[0053] Water flows along the water channel 63 to the rotating shaft 417, then flows downward along the rotating shaft 417, passes through the gap between the rotating shaft 417 and the lifting plate 413, flows to the soil scraper 414, and flows to the ground along the arc-shaped channel 4141.

[0054] The working principle of this invention is as follows: The drilling mechanism 2 moves downward, the bottom surface of the anti-backfill truncated cone 232 contacts the ground, the liftable drill bit 22 moves downward to drill a hole in the ground, the drilled soil slides down the slope of the anti-backfill truncated cone 232 and is blocked by the anti-backfill truncated cone 232, after drilling is completed, the drill bit 22 retracts, and the drilling mechanism 2 rises; the seeder moves forward, aligning the first fertilization mechanism 31 with the hole in the ground, the first fertilization mechanism 31 applies base fertilizer in the hole, and at the same time the drilling mechanism 2 continues to drill; the seeder moves forward... The forward movement aligns the axis of the rotating shaft 417 of the first backfilling mechanism 41 with the hole where base fertilizer has been applied. The lifting and rotating part 411 drives the lifting plate 413, the rotating shaft 417, and the soil scraper 414 to move downward, so that the soil scraper 414 contacts the ground. The lifting and rotating part 411 drives the rotating shaft 417 to rotate, which in turn drives the soil scraper 414 to rotate. Under the action of the guide shaft 418 and the guide groove 4131, the rotation radius of the soil scraper 414 decreases, gathering the drilled soil together and filling part of it into the hole. At the same time, the drilling mechanism 2 continues drilling. The first fertilization mechanism 31 continues to apply base fertilizer to the holes; the seeder moves forward, aligning the sowing mechanism 5 with the holes that have been partially filled with soil, and sowing mechanism 5 sows seeds in these holes. Simultaneously, the drilling mechanism 2 continues drilling, the first fertilization mechanism 31 continues to apply base fertilizer, and the first soil-filling mechanism 41 continues to fill soil. The seeder moves forward, aligning the second fertilization mechanism 32 with the holes after sowing, and applies top dressing fertilizer. Simultaneously, the drilling mechanism 2 continues drilling, the first fertilization mechanism 31 continues to apply base fertilizer, and the first soil-filling mechanism 41 continues to fill soil. Sowing... Mechanism 5 continues sowing; the seeder moves forward, aligning the axis of the rotating shaft 417 of the second filling mechanism 42 with the hole for applying the base fertilizer. The second filling mechanism 42 fills the excavated soil. When the soil scraper 414 rotates to a position close to the center, the arc-shaped soil scraper 414 can compact the freshly filled soil. The irrigation mechanism 6 delivers water to the soil scraper 414 for irrigation. At the same time, the drilling mechanism 2 continues drilling, the first fertilization mechanism 31 continues to apply base fertilizer, the first filling mechanism 41 continues to fill soil, and the sowing mechanism 5 continues sowing.

[0055] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
