Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a soybean quantitative seeder. Background Technology

[0002] A soybean planter is a mechanical device used for planting soybeans and other crops. It is driven by electricity or human power to transport soybean seeds from a container to the planting device, and then places the seeds into the soil by rotation or movement, thereby improving planting efficiency and harvest quality. Existing planters often use seed metering devices to achieve quantitative seed metering. Depending on their function and structure, seed metering devices include horizontal disc type, eye wheel type, spoon disc type, perforated belt type, and pneumatic seed metering devices, thus realizing quantitative sowing of soybeans.

[0003] Existing quantitative soybean planters can precisely distribute soybeans, but due to the presence of weeds and other debris in the soil causing uneven soil distribution, soybeans often bounce when they land on the soil, resulting in uneven distribution and poor planting effect. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a soybean quantitative planter. The soil cutting wheel makes the soil more uniform, the furrowing and planting mechanism makes the furrows in the soil more neat, the pressing wheel makes the soybeans covered with soil more evenly and densely, and the perforated nails improve the soil aeration, thereby improving the soybean planting effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a soybean quantitative planter, including a frame, two cutting wheels symmetrically arranged on the front side of the frame, two pressing wheels arranged on the rear side of the frame, a furrowing and sowing mechanism arranged between the cutting wheels and the pressing wheels, and a seed metering device connected to the furrowing and sowing mechanism. The inlet of the seed metering device is connected to a seed box. Both the furrowing and sowing mechanism and the seed metering device are arranged on the frame.

[0006] The cutting wheel includes a wheel axle rotatably mounted on the frame, two cutting discs rotatably mounted on the wheel axle, and several cross-cutting plates arranged in an array between the two cutting discs. The side of the pressing wheel is provided with several perforated nails.

[0009] The furrowing and sowing mechanism includes a vertical support mounted on the frame, a furrowing blade and a soil retainer that are detachably connected to the vertical support, the furrowing blade being positioned toward the cutting wheel, and the soil retainer being positioned toward the pressing wheel.

[0010] The bottom end of the upright is provided with a seed dropping groove. The soil retainer includes soil retaining soft plates on both sides of the seed dropping groove and a connecting block that can be detachably connected to the upright. The soil retaining soft plates are all connected to the connecting block. The discharge port of the seed metering device is connected to the seed dropping groove through a seed metering pipe.

[0011] A first synchronous belt pulley is provided on the axle, and a second synchronous belt pulley is provided on the output shaft of the seed metering device. A first synchronous belt is tensioned between the first synchronous belt pulley and the second synchronous belt pulley.

[0017] (2) Equipped with a geared motor, on the one hand, when the seeder is connected to the tractor, the geared motor does not run, and the press wheel and the cutting wheel drive the seed metering device to sow soybeans. On the other hand, when the seeder is not connected to the tractor and runs independently, the geared motor drives the seed metering device, and at the same time, the synchronous belt pulley connected to the seed metering device drives the cutting wheel and the press wheel to rotate, thereby realizing the forward movement of the seeder. Soybean sowing can be achieved without connecting to the tractor. The seeder has strong adaptability. Furthermore, when the seeder is connected to the tractor, if no soybeans are placed in the seed box, the speed of the geared motor is started and adjusted, and the tractor drives the seeder forward.

The inlet of the seed metering device 5 is connected to a seed box 51. Both the furrowing and sowing mechanism 4 and the seed metering device 5 are arranged on the frame 1.

[0027] The cutting wheel 2 includes a wheel axle 21 rotatably mounted on the frame 1, two cutting discs 22 rotatably mounted on the wheel axle 21, and several cross-cutting plates 23 arranged in an array between the two cutting discs 22. The side of the pressing wheel 3 is arranged with several perforated nails 31.

[0028] The side of the press roller 3 is provided with a concave surface for piling soil, and the perforated nail 31 is provided on the concave surface. The side of the press roller 3 is provided with a steel brush 32 for cleaning the perforated nail 31.

[0029] The cutting disc 22 has a serrated edge, and the outer edge of the cross-cutting plate 23 is provided with a blade 231.

[0030] The furrowing and sowing mechanism 4 includes a support 41 mounted on the frame 1, a furrowing blade 42 and a soil retainer 43 that are detachably connected to the support 41, the furrowing blade 42 facing the cutting wheel 2, and the soil retainer 43 facing the pressing wheel 3.

[0031] The bottom end of the support 41 is provided with a seed drop trough 44. The soil retainer 43 includes soil retaining soft plates 431 on both sides of the seed drop trough 44 and connecting blocks 432 that can be detachably connected to the support 41. The soil retaining soft plates 431 are all connected to the connecting blocks 432. The discharge port of the seed metering device 5 is connected to the seed drop trough 44 through the seed metering pipe 45.

[0032] A timing pulley 211 is provided on the axle 21, and a timing pulley 52 is provided on the output shaft of the seed metering device 5. A timing belt 6 is tensioned between the timing pulley 211 and the timing pulley 52.

[0033] The press wheel 3 is coaxially equipped with a timing pulley 33, and a timing belt 7 is tensioned between the timing pulley 33 and the timing pulley 52.

[0035] A drawbar 9 is installed on the frame 1, and the frame 1 is connected to the tractor through the drawbar 9.

[0036] The specific working process of this utility model:

[0037] In use, the seeder is connected to the tractor via the drawbar 9. The seed box 51 is filled with soybeans. The tractor drives the seeder across the ridges. First, the cutting wheel 2 rolls on the soil, and the cutting disc 22 and cross-cutting plate 23 of the cutting wheel 2 break up the soil and initially cut long weeds and other debris, making the soil more uniform. Then, the furrowing knife 42 cuts furrows into the soil surface, further cutting weeds and making the furrows neater. Subsequently, soybean seeds from the seed metering device 5 pass sequentially through the seed metering tube 45. The seed trough 44 is dropped into the pre-dug trench. Then, the two retaining plates 431 of the soil retainer 43 cover the soybeans with the soil from both sides of the trench, completing the initial soil covering operation. Subsequently, the concave surface of the compaction wheel 3 gathers the soil covering, making it more abundant, denser, and more uniform, thus improving the soybean sowing effect. The perforation nail 31 makes ventilation holes in the soil covering, preventing the soil covering from being too dense. At the same time, it can further break up the soil, making the soil more breathable and uniform, further improving the soybean sowing effect.

[0038] The soil cutting wheel 2 makes the soil more uniform, the furrowing and sowing mechanism 4 makes the furrows in the soil more neat, the pressing wheel 3 makes the soybean covering soil more uniform and dense, and the hole nail 31 makes the soil more breathable, thus improving the soybean planting effect.

[0039] On the one hand, when the seeder is connected to the tractor, the reduction motor 8 does not run, and the seed metering device 5 is driven by the press wheel 3 and the soil cutting wheel 2 to sow soybeans. On the other hand, when the seeder is not connected to the tractor, the reduction motor 8 drives the seed metering device 5, and at the same time, the synchronous belt pulley 52 connected to the seed metering device 5 drives the soil cutting wheel 2 and the press wheel 3 to rotate, thereby realizing the forward movement of the seeder. Soybean sowing can be achieved without connecting to the tractor. The seeder has strong adaptability. At the same time, when the seeder is connected to the tractor, if there are no soybeans in the seed box 51, the speed of the reduction motor 8 is started and adjusted, and the tractor drives the seeder forward. The rapid rotation of the soil cutting wheel 2 and the press wheel 3 can achieve the effect of loosening the soil, which has a multi-functional effect.

[0040] The seed metering device 5 in this utility model is implemented using existing technology, and will not be described in detail here.

[0041] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
