Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a pressure-adjustable seeding leg and a tillage machine equipped with the seeding leg. Background Technology

[0002] The double-disc furrow seeder assembly is used for furrowing, seeding, backfilling, and compacting soil on rotary-tilled land. During operation, the seeds must be compacted to prevent air leakage and avoid affecting germination. Depending on the soil type, the compaction roller applies varying forces to press the seedbed during compaction.

[0003] The existing seeder assembly can only open furrows and backfill soil, but cannot adjust the pressure according to the soil or compact the seedling strip. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-adjustable sowing method that allows for adjusting the compaction pressure according to soil hardness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable pressure double-disc furrow seeder, the seeder includes a main support leg, a furrow-opening double disc is installed at the bottom of the main support leg, and a pair of rotating connecting parts are rotatably connected to the front end of the main support leg; a pressing mechanism is installed at the rear end of the main support leg, and a telescopic part is provided between the main support leg and the pressing mechanism.

[0006] This utility model also provides another technical solution: a land reclamation and seeding machine, which further includes front and rear support beams and transverse support beams connected to each other. The front end of the front and rear support beams is rotatably connected to the land reclamation machine, and a plurality of clamping seats are installed on the transverse support beam. The other end of a pair of rotating connecting parts is rotatably connected to the clamping seats.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] By incorporating a compaction mechanism with telescopic components, operators can adjust the compaction force of a single compaction wheel on the ground according to the soil conditions.

[0009] The combination of a single-wheel compactor and a double-disc furrowing system ensures that each seed receives stable furrowing and compaction, guaranteeing sowing quality. Furthermore, the front-to-back double-disc furrowing system prevents soil from getting trapped, achieving effective soil separation.

[0010] Meanwhile, the elastic components installed between the rotating connectors can also allow the main support leg to return to its initial position in a timely manner after changes in soil level. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-2 This utility model provides a technical solution: an adjustable pressure double-disc furrow seeder, the seeder including a main support leg 6, the bottom of which is equipped with a furrow-opening double disc 7 for furrowing the soil, facilitating backfilling after seed sowing. A pair of rotating connectors 8 are rotatably connected to one end of the front end of the main support leg 6. The rotating connectors 8 are used to mount the entire seeder leg. Since there is a pair of rotating connectors 8, the main support leg 6 connected to them can form a four-bar linkage structure, allowing the main support leg 6 to move freely up and down to adapt to different ground conditions.

[0018] A compaction mechanism is installed at the rear end of the main support leg 6 for backfilling the soil after sowing. The compaction mechanism includes a support frame 11, one end of which is rotatably connected to the main support leg 6, and a compaction wheel 12 is installed at the other end of the support frame 11. A soil-covering spring 17 is installed on the side wall of the support frame 11 to level the compacted soil. A scraper 19 is installed on the support frame 11 via a bridge to scrape off the compaction wheel 12.

[0019] A telescopic component 3 is provided between the main support leg 6 and the compaction mechanism. While ensuring elasticity, it allows for adjustment of the telescopic length as needed, thereby adjusting the compaction pressure for different soil conditions. The telescopic component includes a first screw 301, a second screw 302, a mounting cylinder 303, and a mounting cap 304. A first nut 305 is screwed onto the first screw 301, and the first screw 301 passes through the mounting cap 304, with the first nut 305 locking inside the mounting cap 304. A second nut 306 is provided on the inner wall of one end of the mounting cylinder 303, and an external thread is provided on the outer wall of the other end of the mounting cylinder 303. The mounting cap 304 has an internal thread, and the internal thread of the mounting cap 304 mates with the external thread of the mounting cylinder 303, allowing for adjustment of the screwed-in position. The second screw 302 is screwed onto the second nut 306. A spring 307 is fitted onto both the first screw 301 and the second screw 302, with both ends of the spring 307 abutting against the first nut 305 and the second nut 306, respectively. Since the screwed positions of the mounting cap 304 and the mounting sleeve 303 are adjustable, the distance between the first screw 301 and the second screw 302 is adjustable. Due to the elasticity of the spring 307, its expansion and contraction can reduce the impact on the compaction effect when the soil height changes.

[0020] Meanwhile, the first screw 301 is rotatably connected to the main support leg 6, and the second screw 302 is rotatably connected to the bracket 11, so that the angle between the main support leg 6 and the pressing wheel 12 is adjustable.

[0021] To allow the main support leg 6 to return to its initial position, an elastic element is provided between the pair of rotating connecting parts 8. This elastic element includes a second spring 13 and a connecting rod 14 connected to each other. The connecting rod 14 has several openings 15. One side of the rotating connecting part 8 is connected to the second spring 13, and the other side is connected to the openings 15 via a pin. By adjusting the connection position between the rotating connecting part 8 and the openings 15 on the connecting rod 14, the extension length of the second spring 13 changes. This changes the elastic force of the second spring 13 between the pair of rotating connecting parts 8, thereby altering the return speed of the main support leg 6.

[0022] Working principle: When in use, a pair of rotating connectors 8 connected to the main support leg 6 are rotatably connected to the reclamation equipment. At this time, the reclamation equipment moves continuously, driving the ditching double discs 7 to move continuously. Seeds are placed at the ditching position, and then the seeds will be compacted by the compaction single wheel 12.

[0023] When it is necessary to adjust the pressing force of the single pressing wheel 12, only the overall length of the telescopic component 3 needs to be adjusted. At this time, the mounting cap 304 needs to be rotated to change its position on the mounting cylinder 303. Due to the limiting effect of the mounting cap 304 on the first nut 305 and the elasticity of the spring 307, the distance between the first screw 301 and the second screw 302 changes, thus allowing the pressing force of the single pressing wheel 12 to be adjusted.

[0024] Please see Figures 3-4 This utility model also provides another technical solution: a land reclamation and seeding machine, which further includes front and rear support beams 1 and a transverse support beam 5 connected to each other. The front end of the front and rear support beams 1 is rotatably connected to a land reclamper 2. One end of a hydraulic cylinder 16 is rotatably connected to the land reclamper 2, and the other end of the hydraulic cylinder 16 is rotatably connected to the cylinder pull beam of the front and rear support beams 1. When the machine is in an unloaded state, the output end of the hydraulic cylinder 16 is shortened so that the land reclamper 2 does not contact the ground. When the land reclamper 2 is in a working state, the hydraulic cylinder 16 is extended so that the land reclamper 2 contacts the ground, at which time the land reclamper 2 is working normally.

[0025] Several clamping seats 9 are installed on the transverse support beam 5, and the other end of a pair of rotating connectors 8 is rotatably connected to the clamping seats 9. In order to ensure that the trenching double discs 7 can be staggered, the clamping seats 9 include long clamping seats and short clamping seats, and the long clamping seats and short clamping seats are staggered. This achieves the effect of preventing soil from getting trapped and effectively separating the soil.

[0026] The tillage seeder also includes a seed box 4 and a standing platform 18. Support plates 20 are provided at both ends of the transverse support beam 5. The seed box 4 is mounted on the support plates 20 and is used to hold seeds. One end of the seeding tube 10 is installed in the seed box 4, with the other end of the seeding tube 10 facing the furrowing disc 7, enabling sowing after tillage. Step mounting plates 21 are installed on both sides of the standing platform 18, and the step mounting plates 21 are mounted on the support plates 20, allowing operators to stand directly on them.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
