Description

Technical Field

[0001] This invention relates to the field of water film planting technology, specifically to a self-propelled sunflower air-suction precision sand-covering planter for water film planting. Background Technology

[0002] Through years of practical experience, farmers have developed a method for planting sunflowers in water-film fields. This method involves covering the soil with film before sowing and then irrigating. Sowing is then carried out when the field humidity is suitable, and the seed holes are covered with sand. Currently, this planting method relies entirely on manual labor, lacking specialized sowing machinery. This mismatch between agricultural machinery and agronomy in water-film planting severely restricts the level of mechanized sunflower cultivation in saline-alkali land. Summary of the Invention

[0017] As a further technical solution, the unloading component also includes:

[0018] An elastic element is provided at both ends on the two swinging elements, and the elastic element is used to provide a closing force for the two swinging elements.

[0028] As a further technical solution, the seeding component also includes:

[0029] Interval sand-falling assembly, the interval sand-falling assembly comprising:

[0030] A housing is mounted on a frame, with the inlet end of the housing connected to the outlet end of the sand box; two first discharge plates are arranged at an angle relative to each other inside the housing, forming a first discharge port, which is connected to the outlet end of the sand box.

[0031] The second feeding plate has two plates, which form a second feeding port. The second feeding port is connected to the first feeding port and is also connected to the sand-feeding cavity.

[0045] The working principle and beneficial effects of this invention are as follows:

[0046] In this invention, sand is used to cover the seeds in the seed holes during sowing in a wet film field. The loose sand allows the seeds to come into contact with air, promoting germination and preventing the soil from hardening and hindering seedling emergence. This avoids problems such as decreased germination rate and bird damage during the seedling stage caused by soil compaction. However, existing equipment cannot achieve spot sowing and sand covering on film in sunflower wetland conditions. The frame moves at a constant speed in the wet film field under the action of the walking component. The roller of the sowing component contacts the ground. The sand box is pre-filled with sand. The roller has a feeding component, and the sand feeding cavity and the seed feeding cavity of the roller are connected. The seeds can be fully mixed in the roller. Then, under the action of the feeding component, the seeds are sown into the wet film field, so that the seeds are mixed with the sand seeds, avoiding the situation where the seeds are exposed. This solves the problem that existing equipment cannot achieve spot sowing and sand covering on film in sunflower wetland conditions. Attached Figure Description

[0059] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0060] Example

[0061] like Figures 1-2 As shown, this embodiment proposes...

[0062] A self-propelled sunflower air-suction precision sand-covering seeder for water-film planting includes:

[0063] Rack 1;

[0064] The seeding component 2 is a plurality of such components, which are arranged at intervals and rotate on the frame 1.

[0065] Walking component 3 is mounted on frame 1;

[0066] Seeding component 2 includes:

[0067] Roller 4 is rotatably mounted on frame 1. Roller 4 has a seeding cavity 5 and a sand-feeding cavity 6.

[0068] Sand box 7 is installed on frame 1 and is connected to sand chamber 6;

[0069] The feeding component 8 is a plurality of components, which are arranged circumferentially on the roller 4. The seeding cavity 5 and the sand-feeding cavity 6 are both connected to the feeding component 8 for sowing seeds.

[0070] In this embodiment, when sowing in a wet film field, sand is covered over the sowing holes to cover the seeds. The loose sand allows the sown seeds to come into contact with air, promoting germination, and also prevents the soil from hardening and obstructing seedling emergence. This avoids problems such as decreased germination rate and bird damage during the seedling stage caused by soil compaction. However, existing equipment cannot achieve spot sowing and sand covering on film under sunflower wetland conditions. The frame 1 moves at a constant speed in the wet film field under the action of the walking component 3. The roller 4 of the sowing component 2 contacts the ground. The sand box 7 is pre-filled with sand. The roller 4 has a feeding component 8, and the sand feeding cavity 6 and the seed feeding cavity 5 of the roller 4 are connected. The seeds can be fully mixed in the roller 4, and then sown into the wet film field under the action of the feeding component 8, so that the seeds can be mixed with the sand seeds, avoiding the situation where the seeds are exposed. This solves the problem that existing equipment cannot achieve spot sowing and sand covering on film under sunflower wetland conditions.

[0071] Furthermore, the inner wall of the roller 4 has protrusions 9, and the unloading component 8 includes:

[0072] Two swinging members 10 are respectively hinged on both sides of the drum 4. The two swinging members 10 form a feeding cavity. After swinging, they are used to open or close the feeding cavity.

[0073] There are two opening and closing devices 11, which are respectively disposed above the swing member 10. The opening and closing devices 11 cooperate with the protrusion 9 to open and close.

[0074] In this embodiment, the feeding component 8 includes two swinging components 10. The swinging components 10 are hinged on both sides of the drum 4. After the swinging components 10 come into contact with the soil as the drum 4 rotates, the protrusion 9 and the opening and closing device 11 on the swinging component 10 cooperate. Both swinging components 10 rotate around the hinge point, and the feeding cavity opens, thereby sowing the seeds and sand from the feeding cavity into the soil.

[0075] Furthermore, after one end of the two swinging parts 10 is closed, a cone-shaped ground-breaking end 12 is formed.

[0076] In this embodiment, after the two swinging components 10 of this solution are closed, they form a pointed cone-shaped soil-breaking end 12, which can directly break the film and then sow seeds under the film through the feeding cavity opened by the swinging component 10. The traditional film-breaking component and sowing component 2 are integrated into one, making the structure simpler, more practical and convenient, and greatly reducing the error rate.

[0077] Furthermore, component 8 also includes:

[0078] The elastic element 13 has two ends respectively disposed on the two swinging elements 10. The elastic element 13 is used to provide the closing force of the two swinging elements 10.

[0079] In this embodiment, the two swinging members 10 are provided with elastic members 13. After the swinging member 10 breaks the film, it opens under the action of the opening and closing device 11 and the protrusion 9, and seeds are sown inside the film. After the swinging member 10 no longer contacts the soil, the swinging member 10 closes under the action of the elastic member 13.

[0080] Furthermore, the roller 4 has a feed inlet 14, which is connected to the seeding cavity 5. The seeding assembly 2 also includes:

[0081] Storage bin 15 is mounted on frame 1;

[0082] An intermittent seeding assembly 16 is mounted on the frame 1. The feed end of the intermittent seeding assembly 16 is connected to the storage bin 15, and the discharge end of the intermittent seeding assembly 16 is connected to the feed inlet 14 of the roller 4. The intermittent seeding assembly 16 includes:

[0083] Seed dispensing chamber 17 is mounted on frame 1;

[0084] The air intake component 18 is mounted on the frame 1 and is connected to the seed dispensing chamber 17;

[0085] A rotating disk 19 is rotatably mounted on the seed dispensing chamber 17. The rotating disk 19 has a number of adsorption holes 39, which are used to sequentially adsorb the seeds in the seed dispensing chamber 17.

[0086] A paddle 20 is installed on the seed dispensing chamber 17. The paddle 20 is used to move the seeds adsorbed on the adsorption holes 39.

[0087] In this embodiment, the solution includes an intermittent seeding component 16, which is connected to a storage bin 15. The storage bin 15 is used to hold seeds, and the seed discharging chamber 17 of the intermittent seeding component 16 is used to hold seeds. The suction component 18 adsorbs the seeds in the seed discharging chamber through the adsorption holes 39 of the rotating disk 19. The rotating disk 19 is rotatably mounted on the seed discharging chamber 17. After rotation, the paddle 20 moves the seeds adsorbed on the adsorption holes 39, causing the seeds to fall into the roller 4, thereby realizing intermittent seed discharging and avoiding multiple seeds being discharged from the discharging component 8 at the same time, which would cause waste.

[0088] Furthermore, the seeding component 2 also includes:

[0089] Scraper 21 is mounted on frame 1 and is used to clean the soil attached to swinging component 10.

[0090] In this embodiment, since the feeding part 8 will come into contact with the soil during the sowing process, in order to avoid the oscillating part 10 from getting stuck with soil and affecting the opening and closing of the oscillating part 10, this solution provides a scraper 21 on the frame 1, which can scrape off the soil on the oscillating part 10 after the oscillating part 10 rotates with the roller 4.

[0091] Furthermore, the seeding component 2 also includes:

[0092] Interval sand-falling component 23, the interval sand-falling component 23 includes:

[0093] The housing 36 is mounted on the frame 1, and the feed end of the housing 36 is connected to the discharge end of the sand box 7.

[0094] There are two first feeding plates 24, which are arranged at an angle to each other inside the box 36. The two first feeding plates 24 form a first feeding port 38, which is connected to the discharge end of the sand box 7.

[0095] The second feeding plate 25 has two parts, and the two second feeding plates 25 form a second feeding port 22. The second feeding port 22 is connected to the first feeding port 38 and is also connected to the sand discharge cavity 6.

[0096] There are two mounting plates 26, both of which are disposed on the second feeding plate 25 and are located at both ends of the second feeding port 22 respectively.

[0097] Mounting component 27 is mounted on the second feeding plate 25 and located at the second feeding port 22;

[0098] The rotating shaft 28 is rotatably mounted on the mounting part 27 with the mounting part 27 as the center, and the two ends of the rotating shaft 28 have external threads in opposite directions;

[0099] There are two rotating sleeves 29, and the two rotating sleeves 29 are respectively symmetrically threaded on both sides of the rotating shaft 28;

[0100] Two skateboards 30 are slidably mounted on two mounting plates 26 respectively.

[0101] The hinge rod 31 has several parts, one end of which is hinged to one of the two slide plates 30, and the other end is hinged to one of the two rotating sleeves 29.

[0102] The drive unit 32 is located at one end of the rotating shaft 28 and is used to drive the rotating shaft 28 to rotate. After rotation, the rotating sleeve 29 drives the slide plate 30 to slide through the hinge rod 31.

[0103] In this embodiment, since the amount of sand is relatively large, to prevent the sand from sinking to the bottom and leaving the seeds exposed on the sand, this solution is equipped with an interval sand feeding component 23 to feed sand in a quantitative manner. Each time a seed is dropped, the next batch of sand can cover the seed. This solution is equipped with a first feeding plate 24, and the sand is fed through the first feeding port 38 formed by the first feeding plate 24. The sand fed by the first feeding plate 24 reaches the slide plate 30 of the second feeding plate 25. The slide plate 30 is slidably mounted on the mounting plate 26. This solution is equipped with a pressure sensor below the mounting component 27. When a certain amount of sand falls onto the second mounting plate 26, the pressure sensor transmits a signal to the drive unit 32. The drive unit 32 drives the rotating shaft 28 to rotate, and the rotating sleeve 29 slides with the rotation of the rotating shaft 28, thereby driving the hinge rod 31. The hinge rod 31 drives the slide plate 30 to slide, so that the second feeding port 22 opens. The sand falling on the second feeding plate 25 falls into the sand feeding cavity 6 of the roller 4 as the second feeding port 22 opens.

[0104] Furthermore, the interval sand component 23 also includes:

[0105] The rotating roller 33 is rotatably disposed inside the housing 36 and located at the first discharge port 38;

[0106] There are several rake rods 34, and all of the rake rods 34 are arranged on the rotating roller 33.

[0107] In this embodiment, to prevent sand from clogging during the process of feeding from the first discharge port 38, a rotating roller 33 is provided above the first discharge port 38, and a rake 34 is provided on the rotating roller 33 to loosen the sand and prevent clogging.

[0108] Furthermore, the walking component 3 includes:

[0109] There are several traveling wheels 35, and all of the several traveling wheels 35 are mounted on the frame 1;

[0110] Steering wheel 37 is used to control the direction of travel of the walking wheels 35.

[0111] In this embodiment, the device is equipped with a walking component 3 on the frame 1 to control the device to walk at a constant speed in the water film, and the direction of the device's movement is controlled by the steering wheel 37.

[0112] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
