Description

Technical Field

[0001] This utility model belongs to the field of artificial grassland establishment technology, specifically a strip seeder for establishing artificial grassland. Background Technology

[0002] Artificial grassland establishment refers to the process of cultivating suitable grass seeds into grasslands with certain productivity and utilization value through human planning, land preparation, sowing, and management. When it is necessary to establish artificial grasslands in areas suitable for grass growth (such as riverbanks and meadow grasslands in temperate and cold regions), and to ensure accurate and uniform sowing of grass seeds, and to guarantee appropriate sowing depth and row spacing to improve germination rate and grassland establishment quality, grass seed sowers are used.

[0003] The existing utility model with authorization announcement number CN209072884U discloses an integrated small-area row seeder, including a connecting rod, a seed box, a plow head, and a soil covering device. During the process of driving the connecting rod forward, it can realize the entire process of turning the soil, sowing, and covering the soil. The whole process is time-saving and labor-saving, which can significantly improve the sowing efficiency and thus save sowing costs. Moreover, the entire row seeder has a simple structure, is easy to operate, and is lightweight, making it suitable for small-area sowing.

[0004] While the above-mentioned technical solution can realize the entire process of tilling, sowing, and covering, it is inconvenient to adjust the tilling depth and lacks a convenient tilling depth adjustment structure, which makes it difficult to flexibly control the sowing depth and thus difficult to adapt to different soil conditions in different regions.

[0005] To address these issues, we propose a strip seeder for establishing artificial grasslands. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the existing technology lacks a convenient structure for adjusting the plowing depth, which makes it inconvenient to flexibly control the sowing depth and thus difficult to adapt to different soil conditions in different regions. Therefore, this invention proposes a strip seeder for establishing artificial grassland.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a strip seeder for establishing artificial grassland, comprising a counterweight trolley, a shaped frame fixedly connected to the front end of the counterweight trolley, a sowing mechanism fixedly connected to both sides of the upper end of the shaped frame via mounting seats, a soil covering plate fixedly connected to one side of the bottom surface of the shaped frame, a support frame fixedly connected to the inner side of the shaped frame, a hand-tightening adjusting threaded rod threadedly connected to the inner wall of the support frame, a limiting lifting slide plate slidably connected inside the support frame, an auxiliary bearing fixedly connected to the inner wall of the limiting lifting slide plate, four plowshares fixedly connected to the bottom surface of the limiting lifting slide plate, and the inner ring of the auxiliary bearing fixedly connected to the outer surface of the hand-tightening adjusting threaded rod. The limiting lifting slide plate, the sowing mechanism, and the soil covering plate are sequentially arranged on the shaped frame in a direction gradually moving away from the counterweight trolley.

[0008] Furthermore, the sowing mechanism includes a sowing box, a conical funnel, and a seed outlet head. The two sides of the sowing box are fixedly connected to the top of the mounting base. The bottom surface of the sowing box is fixedly connected to four conical funnels, which are arranged vertically downwards. Each conical funnel has a seed outlet head threadedly connected to its bottom end.

[0009] Furthermore, the top of the seeding box has strip-shaped insertion holes on opposite sides, and a transparent baffle is slidably disposed in the strip-shaped insertion holes, the size of which matches the seeding box.

[0010] Furthermore, a limiting tray is fixedly connected to the upper surface of the counterweight trolley, and a storage box is provided above the counterweight trolley. The storage box is placed inside the limiting tray, and the outer surface of the storage box is in contact with the inner wall of the limiting tray.

[0011] Furthermore, a pull rod is fixedly connected to the upper end of the counterweight trolley on the side away from the irregular frame, and an anti-slip sleeve is fixedly connected to the outer surface of the pull rod.

[0012] This utility model has the following advantages compared with the prior art:

[0013] By coordinating a counterweight trolley, a custom-shaped frame, a soil covering plate, a support frame, a hand-tightened adjusting threaded rod, a limiting lifting slide plate, an auxiliary bearing, and a plow head, the auxiliary bearing prevents the limiting lifting slide plate from rotating synchronously with the threaded rod when the hand-tightened adjusting threaded rod is turned. Instead, the limiting lifting slide plate slides only along the inside of the support frame, thereby adjusting the height of the plow head and achieving flexible control of the plowing depth. This structure requires no complex electronic control components; the purely mechanical adjustment method is convenient to operate and highly stable. It can quickly adapt to the sowing depth requirements of different regional soil conditions (such as soft soil in riverbanks in temperate and cold regions and compact soil in meadow steppes), ensuring that grass seeds are at the appropriate depth to improve germination rate. At the same time, the soil covering plate fixed by the custom-shaped frame can cover the soil promptly after sowing, eliminating the need for additional soil covering steps and improving row sowing efficiency. This effectively solves the problem of poor adaptability caused by the lack of a convenient plowing depth adjustment structure in existing technologies, avoiding the inconvenience of flexibly controlling the sowing depth due to the lack of a convenient plowing depth adjustment structure, thus preventing the adaptation of grass to different regional soil conditions.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 6The illustrated row seeder for establishing artificial grassland includes a counterweight trolley 1, which is a common flatbed trolley. A special-shaped frame 2 is fixedly connected to the front end of the counterweight trolley 1. The special-shaped frame 2 has a frame structure. Seeding mechanisms are fixedly connected to both sides of the upper end of the special-shaped frame 2 via mounting seats 17. Two mounting seats 17 are symmetrically arranged. A soil covering plate 3 is fixedly connected to one side of the bottom surface of the special-shaped frame 2. A support frame 4 is fixedly connected to the inner side of the special-shaped frame 2. A hand-tightening adjusting threaded rod 5 is threadedly connected to the inner wall of the support frame 4. A limit lifting slide plate 6 is slidably connected to the inside of the support frame 4 via a sliding groove slider structure. The inner wall of the limit lifting slide plate 6 is fixedly connected to the outside of the auxiliary bearing 7. Four plowshares 8 are fixedly connected to the bottom surface of the limit lifting slide plate 6. The inner ring of the auxiliary bearing 7 is fixedly connected to the outer surface of the hand-tightening adjusting threaded rod 5. The limit lifting slide plate 6, the seeding mechanism, and the soil covering plate 3 are arranged sequentially on the special-shaped frame 2 in a direction that gradually moves away from the counterweight trolley 1.

[0023] The sowing mechanism includes a sowing box 13, a conical funnel 15, and a seed outlet head 16. The top of the sowing box 13 is open, and both sides of the sowing box 13 are fixedly connected to the top of the mounting base 17. The bottom of the mounting base 17 is fixedly connected to the top of the irregular frame 2. Four conical funnels 15 are fixedly connected to the bottom surface of the sowing box 13. The conical funnels 15 are set vertically downwards, and the bottom of each conical funnel 15 is threadedly connected to the seed outlet head 16. The conical funnel 15 is funnel-shaped with a structure that is wider at the top and narrower at the bottom, which can guide the seeds in the sowing box 13 to flow precisely to the seed outlet head 16. The seed outlet head 16 is threadedly connected to the bottom of the conical funnel 15 for easy disassembly. Different diameter seed outlet heads 16 can be replaced to adapt to the sowing of seeds of different sizes.

[0024] The top of the seed box 13 has strip-shaped insertion holes on opposite sides. The size of the strip-shaped insertion holes is adapted to the outer circumference of the transparent baffle 14. The transparent baffle 14 is slidably installed inside the strip-shaped insertion holes. The length and width of the transparent baffle 14 match the internal length and width of the seed box 13. The transparent baffle 14 can temporarily seal the top of the seed box 13 to prevent the seeds inside from spilling out due to shaking. When adding seeds to the seed box 13, grasp one side of the transparent baffle 14 and pull it outward to add seeds from the top of the seed box 13. After adding seeds, reinsert the transparent baffle 14 into the strip-shaped insertion holes to seal the top of the seed box 13.

[0025] A limiting tray 9 is fixedly connected to the upper surface of the counterweight trolley 1. A storage box 10 is provided above the counterweight trolley 1, and the storage box 10 is placed inside the limiting tray 9. The outer surface of the storage box 10 is in contact with the inner wall of the limiting tray 9. The storage box 10 provides a large seed storage space, reducing the number of trips between the seed warehouse and the planting area. The limiting tray 9 can surround and position the storage box 10, preventing it from shifting or tipping over when the trolley is moved, ensuring stable seed storage, improving sowing continuity, and making it easy to remove the storage box 10 for subsequent cleaning or maintenance.

[0026] A pull rod 11 is fixedly connected to the upper surface of the counterweight trolley 1, and an anti-slip sleeve 12 is fixedly connected to the outer surface of the pull rod 11. The pull rod 11 provides a force point for the operator, making it easy to pull the counterweight trolley 1 to move. It is suitable for small-area artificial turf planting scenarios. The anti-slip sleeve 12 can increase the friction between the hand and the pull rod 11, prevent the hand from slipping when pulling, and at the same time improve the grip comfort and reduce hand fatigue during long-term operation.

[0027] The specific working process of this utility model is as follows:

[0028] Before use, adjust the depth of the plow head 8 according to the soil conditions of the planting area. The operator turns the hand-tightening adjusting threaded rod 5. With the help of the thread, the hand-tightening adjusting threaded rod 5 drives the limiting lifting slide plate 6 to slide smoothly along the inside of the support frame 4, which drives the plow head 8 to move up and down. Adjust the position of the plow head 8 until the plow head 8 reaches the appropriate depth. At this time, stop turning the hand-tightening adjusting threaded rod 5. The sliding cooperation between the limiting lifting slide plate 6 and the support frame 4 can keep the position of the plow head 8 fixed and prevent the plow head 8 from shifting during the sowing process. At the same time, the counterweight trolley 1 provides stable support for the entire equipment, and the irregular frame 2 fixes the support frame 4 and the soil covering plate 3 to ensure the stability of each structure position.

[0029] Next, prepare for sowing by pouring the grass seeds into the storage box 10. The storage box 10 is fixed above the counterweight trolley 1 by the limiting tray 9 to prevent the storage box 10 from shifting when the equipment moves. Select a seed outlet head 16 with a suitable diameter and fix it to the bottom of the conical funnel 15 by threading it. Then, pour an appropriate amount of grass seeds from the storage box 10 into the sowing box 13. Two operators work together to start sowing.

[0030] One operator holds the anti-slip sleeve 12 on the outside of the lever 11 and pulls the counterweight trolley 1 to move it. At the same time, another operator quickly adds an appropriate amount of grass seeds into the seeding box 13 through a handheld small shovel until the seeds are about two-thirds full. The transparent baffle 14 is then inserted. The operators continue to pull the counterweight trolley 1 to sow the seeds.

[0031] The seeds in the seeding box 13 fall downwards into the conical funnel 15, and then through the seed outlet 16 precisely fall into the furrow opened by the plow head 8. As the counterweight trolley 1 continues to move, the soil covering plate 3 at the bottom of the irregular frame 2 scrapes and pushes the soil on both sides of the furrow into the furrow, completing the soil covering operation. This achieves an integrated operation of furrow opening, sowing, and soil covering. The design of the entire strip seeder for establishing artificial grassland effectively solves the problem that the lack of a convenient structure for adjusting the plowing depth makes it inconvenient to flexibly control the sowing depth, thus making it difficult to adapt to different soil conditions in different areas.
