Description

Technical Field

[0001] The utility model relates to the field of furrow openers for seeders, in particular to a grassland seeder for mixed seeding. Background Art

[0002] The grasslands in alpine regions of our country are facing serious ecological problems. Taking the grasslands in Ganzi Prefecture as an example, according to the investigation and statistics, about 78% or more of the grasslands in Ganzi Prefecture have varying degrees of degradation. In particular, the grasslands that are convenient for transportation, flat in terrain, and convenient for grazing have generally degraded. Severely degraded grasslands will evolve into rat wasteland, sandy land, hardened land, and areas densely distributed with miscellaneous poisonous weeds, and then completely lose their utilization value. Therefore, it has become extremely urgent to take necessary measures to solve the ecological problems. In recent years, Ganzi Prefecture has done a lot of work in the ecological restoration of alpine pastoral grasslands, but the progress is relatively slow because there are prominent problems such as low mechanization level and lack of suitable machinery for no-till reseeding. The Chinese invention patent with the publication number of CN2781735Y discloses a direct seeder that uses a rotary tillage method to open furrows. This direct seeder mainly consists of four major parts: a strip rotary tillage and furrow opening device, a fertilizer and seed discharging device, a seedbed treatment device, and a soil covering and pressing device. This direct seeder cannot well adapt to the natural environment of the grasslands in Ganzi Prefecture during production operations. When encountering stones on the ground surface and in the soil during the working process, the strip rotary tillage and furrow opening device cannot bounce up, which will affect the seeding operation.

The cantilever beam 11 is arranged at the lower part of the frame 1, the seed bin 2 is arranged above the frame 1, a plurality of the ditching assemblies 3 are arranged on the cantilever beam 11, and the driving device 4 is arranged at both ends of the cantilever beam 11, wherein:

[0024] Seed discharging ports 5 are arranged on both sides of the bottom of the seed bin 2 along the traveling direction of the ditching assembly 3. The seed discharging ports 5 are multiple and arranged at intervals, and the multiple seed discharging ports 5 are arranged perpendicular to the traveling direction of the ditching assembly 3. A seeder 6 is correspondingly arranged at each seed discharging port 5. The seeder 6 is connected to the ditching assembly 3 through a seed discharging hose. A seed mixing roller 7 is arranged in the feeding port direction of the seed discharging port 5, and a plurality of stirring rods 8 are arranged at intervals on the seed mixing roller 7.

[0025] When the utility model is in use, seeds are put into the seed bin 2 and stirred by the mixing roller 7 driving the stirring rod 8. The stirring rod 8 can destroy the stacking state of the seeds in the seed bin 2, effectively solving the problems of seed blockage and uneven mixing. The stirred seeds are discharged from the furrowing component 3 through the seed discharging hose. The furrowing component 3 realizes furrowing of the ground, and the seeds then fall into the plot with furrows opened, and then the subsequent covering wheel realizes automatic seeding of the seeds.

[0026] Embodiment Two

[0027] This embodiment is developed on the basis of the above embodiment. Specifically, this embodiment discloses the specific structure of the seed bin 2, as Figures 1-4 shown, the side cross-section of the seed box is in a W shape, the seed discharging ports 5 are in two rows and are respectively located on the outer sides of the bottom of the seed box, and the two rows of the seed discharging ports 5 are arranged staggeredly.

[0028] Furthermore, the seed bin 2 further includes a seeding rate adjusting device 9. The seeding rate adjusting device 9 includes: an adjusting handle 91, a seeding shaft 92 and a slider 93. The slider 93 is fixed on the seeding shaft 92, the bottom end of the adjusting handle 91 is hinged to the slider 93, and the middle and lower part of the adjusting handle 91 is hinged to the side wall of the seed box;

[0029] The seeding shaft 92 sequentially passes through each seeder 6, and a seeding wheel 94 is sleeved on the seeding shaft 92 at a position inside the seeder 6. A damping ring 95 is also sleeved on the seeding shaft 92. The damping ring 95 is arranged adjacent to the seeding wheel 94, and the damping rings 95 are all located on the same side of the seeding wheel 94.

[0030] The seeding rate adjusting device 9 is mainly used to adjust the seeding rate. Specifically, it includes: an adjusting handle 91, a seeding shaft 92, a slider 93, a seeding wheel 94 and a damping ring 95. The slider 93 is fixed at the leftmost side of the seeding shaft 92, and the bottom end of the adjusting handle 91 is hinged to the slider 93. The seeding shaft 92 sequentially passes through each seeder 6, and a seeding wheel 94 is sleeved on the seeding shaft 92 at a position inside the seeder 6. At the same time, a damping ring 95 is also sleeved on the seeding shaft 92. The damping ring 95 is arranged adjacent to the seeding wheel 94, and the damping rings 95 at each seeder 6 are all located on the same side of the seeding wheel 94. By the lateral movement of the seeding shaft 92, the damping ring 95 and the seeding wheel 94 alternately appear inside the seeder 6. When the slider 93 is at the initial position on the left side, all the outer groove wheels of the seeding wheel 94 are inside the seeder 6. At this time, the working width of the seeding wheel 94 is the largest and the seeding rate is the largest. When the slider 93 moves horizontally to the right, the working width of the outer groove wheel of the seeding wheel 94 becomes smaller, and at this time the seeding rate decreases.

[0031] Embodiment Three

[0032] This embodiment is developed on the basis of the above embodiment. Specifically, this embodiment discloses the specific structure of the ditching assembly 3, as Figures 1-4 shown. The ditching assembly 3 includes a ditching disc 33, a shock-absorbing assembly 35, a mounting seat 31, a chuck 34, and a connecting plate 32. The mounting seat 31 is fixed on the seeding frame 1. The mounting seat 31 is connected to the ditching disc 33 through the connecting plate 32. Both ends of the central rotating shaft of the ditching disc 33 are movably connected to the connecting plate 32 and the chuck 34 respectively. The mounting seat 31 has an L-shaped portion 36 extending forward along the ditching direction of the ditching disc 33. When the seeding machine moves forward and the ditching assembly 3 hits a stone or other uneven places on the road surface, the ditching assembly 3 bounces upward, driving the connecting plate 32 to rotate around the movable connection point between the connecting plate 32 and the mounting seat 31. The rotation of the connecting plate 32 drives the shock-absorbing assembly 35 to compress, and the compression of the shock-absorbing assembly 35 generates a resilience force to offset the impact force generated when the ditching assembly 3 hits a stone.

[0033] Furthermore, the shock-absorbing assembly 35 includes a screw 351, a compression member 352, and a retaining ring 353. The screw 351 is horizontally arranged along the ditching direction of the ditching disc 33. One end of the screw 351 is connected to the L-shaped portion 36. The retaining ring 353 is arranged at the other end of the screw 351 away from the L-shaped portion 36. The compression member 352 is wound around the screw 351 located between the L-shaped portion 36 and the retaining ring 353. The connecting plate 32 is rotatably connected to one side of the mounting seat 31. Both ends of the connecting plate 32 are rotatably connected to the central rotating shaft of the ditching assembly 3 and one end of the screw 351 close to the L-shaped portion 36 respectively. When the ditching assembly 3 bounces upward, the connecting plate 32 drives the screw 351 to move, and the compression member 352 is compressed to generate a resilience force to offset the impact force.

[0034] Furthermore, the part of the ditching disc 33 in contact with the ground is wavy. The connecting plate 32 is L-shaped, and its middle part is rotatably connected to one side of the mounting seat 31. Both ends of the connecting plate 32 are closer to the front in the ditching direction than its middle part.
