Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a three-link mechanism of a seeder. Background Art

[0002] At present, seeding machines at home and abroad mainly operate individually. A tractor pulls a seeding machine for operation. When sowing large areas of cultivated land, the tractor needs to pull the seeding machine back and forth many times to complete the cultivation of all cultivated land.

[0003] However, during the reciprocating movement of the tractor, the cultivated land soil will be repeatedly rolled, which easily leads to excessive compaction of the soil, affecting the air permeability of the seeds and making it difficult for the seeds to break through the soil, which is not conducive to the germination and growth of the seeds, resulting in a reduction in grain output. In addition, the working efficiency of a single seeding machine is low, increasing the working hours of the tractor and the staff, wasting labor and fuel, and increasing the planting cost. Summary of the Utility Model

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a three-link mechanism of a seeder. By adding a sub-frame body, the number of hanging points is increased. Three seeding machines operate simultaneously. During a single forward movement of the tractor, three rows of ditches are sown at the same time, greatly improving the seeding efficiency, reducing the planting cost, reducing the number of round trips of the tractor, reducing the waste of labor and fuel, avoiding excessive compaction of the soil, being conducive to the germination and growth of seeds, and ensuring the grain output.

[0005] The specific technical solution adopted by the utility model is as follows:

[0006] A three-link mechanism of a seeder includes a main frame body in a triangular structure. The tip of the main frame body is connected to a tractor. Hook hanging points for cooperating with a traction frame are respectively arranged at both ends of the tail of the main frame body. A sub-frame body is also arranged at the tail of the main frame body. Hook hanging points for cooperating with the traction frame are also arranged at the tail of the sub-frame body. The hook hanging points at the tail of the sub-frame body and the tip of the main frame body are on the same straight line and this straight line coincides with the forward direction of the tractor. Three groups of hook hanging points at both ends of the tail of the main frame body and at the tail of the sub-frame body are respectively connected with working units by means of traction frames. The three groups of working units are arranged in an inverted product shape along the forward direction of the tractor.

[0007] The hook hanging points include U-shaped bolts and fixed hooks. The fixed hooks form a detachable fixed connection with the main frame body by means of the U-shaped bolts. The fixed hooks have the freedom to adjust left and right along the tail of the main frame body by means of the tightness and looseness of the U-shaped bolts.

[0008] The traction frame is in a Y-shaped structure. The bifurcated end of the Y-shaped structure is fixedly connected to the working unit. A hook hanging plate is arranged at the tip of the Y-shaped structure. Hook hanging holes for hooking and fixing with the fixed hooks are arranged on the hook hanging plate.

[0009] The auxiliary frame body has a V-shaped structure. A reinforcing beam is also connected between the two sides of the auxiliary frame body. A universal wheel is also arranged below the auxiliary frame body by means of the reinforcing beam, and the universal wheel is located at the midline of the reinforcing beam.

[0010] The main frame body includes inclined beams on both sides and a main cross beam between the ends of the inclined beams on both sides. A reinforcing cross beam and a reinforcing longitudinal beam are also arranged between the two inclined beams on both sides. The reinforcing cross beam and the reinforcing longitudinal beam are coplanar with the plane formed by the main frame body respectively. The reinforcing cross beam is arranged parallel to the main cross beam, and both ends of the reinforcing cross beam are fixedly connected to the inclined beams on both sides respectively. The reinforcing longitudinal beam is perpendicular to the reinforcing cross beam and is arranged along the midline of the reinforcing cross beam.

[0011] Two groups of walking wheels are symmetrically arranged on the main frame body along the advancing direction of the tractor left and right.

[0012] The beneficial effects of the present utility model are as follows:

[0013] On the basis that two hook hanging points are arranged at both ends behind the main frame body in the present utility model, the hook hanging points are increased by means of the auxiliary frame body. Three groups of seeders are arranged in an inverted product shape by means of the hook hanging points. During operation, the seeders can work independently without mutual influence. When turning, they can rotate concentrically without mutual interference. When turning, each seeder turns independently with different radii to ensure flexible turning. The three seeders operate simultaneously, and during a single forward movement of the tractor, three rows of ditches are sown at the same time, greatly improving the seeding efficiency, reducing the planting cost, at the same time reducing the number of round trips of the tractor, reducing the waste of labor and fuel, avoiding excessive compaction of the soil, being beneficial to the germination and growth of seeds, and ensuring the grain yield.

Detailed Embodiment

[0017] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0018] Specific embodiment, such as Figure 1-2As shown in the figure, the utility model provides a three-link mechanism for a seeder, which includes a main frame body in a triangular structure. The tip of the main frame body is connected to a tractor 2. Hook hanging points for cooperating with a traction frame 3 are respectively arranged at both ends of the tail of the main frame body. A sub-frame body 4 is also arranged at the tail of the main frame body. A hook hanging point for cooperating with the traction frame 3 is also arranged at the tail of the sub-frame body 4. The hook hanging point at the tail of the sub-frame body 4 and the tip of the main frame body are located on the same straight line, and this straight line coincides with the advancing direction of the tractor 2. Three groups of hook hanging points at both ends of the tail of the main frame body and at the tail of the sub-frame body 4 are respectively connected with working units 13 by means of the traction frame 3. The three groups of working units 13 are arranged in an inverted character shape along the advancing direction of the tractor 2.

[0019] Currently, seeding machines at home and abroad mainly operate individually. When sowing large areas of cultivated land, the tractor 2 needs to tow the seeding machine back and forth many times to complete the cultivation of all cultivated land. However, during the reciprocating movement of the tractor 2, the cultivated land soil will be repeatedly rolled, which easily leads to excessive compaction of the soil, affecting the air permeability of the seeds and making it difficult for the seeds to break through the soil, which is not conducive to the germination and growth of the seeds, resulting in a reduction in grain output. In addition, the working efficiency of a single seeding machine is relatively low, increasing the working hours of the tractor 2 and the staff, wasting labor and fuel, and increasing the planting cost.

[0020] Therefore, on the basis of setting two hook hanging points at both ends behind the main frame body in the utility model, the hook hanging points are increased by means of the sub-frame body 4. The working unit 13 in the utility model is a seeding machine. The three groups of seeding machines are arranged in an inverted character shape by means of the hook hanging points. During operation, the seeding machines can work independently without interference. When turning, they can rotate concentrically without interference. When turning, each seeding machine turns independently at different radii to ensure flexible turning. The three seeding machines operate simultaneously. During a single forward movement of the tractor 2, sowing is carried out on three rows of ditches at the same time, greatly improving the seeding efficiency, reducing the planting cost, while reducing the number of round trips of the tractor 2, reducing the waste of labor and fuel, avoiding excessive compaction of the soil, being conducive to the germination and growth of the seeds, and ensuring the grain output.

[0021] The hook hanging point includes a U-shaped bolt and a fixed hook 5. The fixed hook 5 forms a detachable fixed connection with the main frame body by means of the U-shaped bolt. The fixed hook 5 has the freedom to adjust left and right along the tail of the main frame body by the tightness of the U-shaped bolt. By tightening or loosening the bolt, the position of the fixed hook 5 can be adjusted, and thus the positional relationship between the seeding machines can be adjusted. The distance between the seeding machines at both ends of the tail of the main frame body is slightly larger than the effective sowing width of the seeding machine behind the sub-frame body 4, which can ensure the space utilization rate of the soil. If the seeds need more growth space, the distance between the seeding machines at both ends of the tail of the main frame body can be increased. In addition, the sub-frame body 4 in the utility model is in an inverted triangle shape. The tip of the sub-frame body 4 is the fixed hook 5. The bifurcated ends of the sub-frame body 4 respectively form a detachable fixed connection with the main frame body by means of the U-shaped bolt.

[0022] The towing frame 3 is in a Y-shaped structure. The bifurcated ends of the Y-shaped structure are fixedly connected to the working unit 13. A hook plate 1 is provided at the tip of the Y-shaped structure. Hook holes for hooking and fixing with the fixed hook 5 are provided on the hook plate 1. The towing frame 3 in the present utility model is a hook in a Y-shaped structure similar to a triangle, and the structure of this hook is more firm.

[0023] In addition, a hook plate 1 is also provided at the tip of the main frame body, and a fixed hook 5 is provided at the tail of the tractor 2. The tip of the main frame body forms a hooking and fixing with the fixed hook 5 of the tractor 2 through the hook hole of the hook plate 1.

[0024] The auxiliary frame body 4 is in a V-shaped structure. A reinforcing beam 6 is also connected between the two sides of the auxiliary frame body 4. A universal wheel 7 is further provided below the auxiliary frame body 4 by means of the reinforcing beam 6. The universal wheel 7 is located at the midline of the reinforcing beam 6. The reinforcing beam 6 can improve the structural strength of the auxiliary frame body 4. At the same time, the universal wheel 7 provided at the bottom of the auxiliary frame body 4 ensures turning and supporting walking.

[0025] The main frame body includes inclined beams 8 on both sides and a main cross beam 9 located between the ends of the inclined beams 8 on both sides. A reinforcing cross beam 10 and a reinforcing longitudinal beam 11 are also provided between the inclined beams 8 on both sides. The reinforcing cross beam 10 and the reinforcing longitudinal beam 11 are coplanar with the plane formed by the main frame body respectively. The reinforcing cross beam 10 is arranged parallel to the main cross beam 9, and both ends of the reinforcing cross beam 10 are fixedly connected to the inclined beams 8 on both sides respectively. The reinforcing longitudinal beam 11 is perpendicular to the reinforcing cross beam 10 and is arranged along the midline of the reinforcing cross beam 10. By adding the reinforcing cross beam 10 and the reinforcing longitudinal beam 11, the structural strength of the main frame body is further increased, and damage to the main frame body is avoided when it is subjected to a large torque during the turning process.

[0026] Two groups of walking wheels 12 are symmetrically arranged on the main frame body along the advancing direction of the tractor 2. The walking wheels 12 are used for support and walking.
