Description

Technical Field

[0001] This utility model belongs to the field of strip seeding technology, specifically relating to a seed strip seeding machine. Background Technology

[0002] A row seeder is an agricultural seeding machine primarily used for the uniform sowing of crop seeds in rows in farmland. Row seeders are suitable for a variety of crops, such as wheat, corn, soybeans, and grass seeds, and their sowing parameters can be adjusted according to the characteristics and planting requirements of different crops. Compared to traditional manual or animal-powered sowing methods, row seeders significantly improve sowing efficiency and reduce the labor intensity of farmers, making them an indispensable tool in the process of modern agricultural mechanization.

[0003] The existing row seeder mainly consists of a furrow opener, a soil covering device, a transmission system, and a seeding device. During operation, the furrow opener first opens a seeding furrow of a certain depth and width in the soil. The seed metering device evenly sows the seeds into the furrows according to the set plant spacing or the number of seeds per hectare. Then, the soil covering device covers the seeds and gently compacts the soil, completing one full sowing cycle.

[0004] However, existing row seeders have relatively limited functions, and these seeding structures often cannot adjust the depth of the furrows during the furrowing process, making it impossible to furrow according to the planting depth requirements of different crops. At the same time, the spacing between the furrows cannot be controlled, and the distance between the furrows cannot be adjusted according to the growth density of the crops. Furthermore, the seed dispensing rate of existing row seeders is not fixed, resulting in uneven sowing, which in turn affects crop production and output value. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a seed row seeder. It utilizes a furrow opener that adjusts the furrow spacing and depth according to the planting density and depth requirements of different crops to create furrows in the land. A drive mechanism rotates the seeding disc, which, in conjunction with the seeding chamber and sealing block, ensures quantitative seed sowing. When the seeding disc rotates until the seeding chamber aligns with the bottom seed outlet, the seeds slide down from the seed outlet along the seeding tube into the furrows created by the furrow opener. A soil-covering roller then covers and flattens the furrows with soil. This machine can perform continuous and quantitative uniform sowing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seed row seeder, including a frame, a seed box mounted on the frame, an adjustable furrowing structure mounted at the front end of the frame, the adjustable furrowing structure including an adjustment mechanism movably mounted on the frame, a furrow opener slidably mounted at the upper limit of the bottom end of the adjustment mechanism, a plurality of seeders mounted at the bottom of the seed box via an mounting plate, a seeding disc rotatably mounted inside the seeder, a drive mechanism for driving the seeding disc to rotate mounted on the frame, and a soil covering roller mounted at the bottom of the rear end of the frame.

[0007] As a preferred embodiment, the adjustment mechanism includes a trenching frame and an adjusting screw. The two ends of the trenching frame pass through the limiting grooves on the frame and are connected to a sliding mounting rod at the bottom of the frame. A row of fastening holes is provided on the mounting rod. The trencher slides on the mounting rod through a mounting sleeve and is fixedly connected to the mounting rod by the fastening screw. The adjusting screw is mounted on the frame through a bracket. The top of the trenching frame is threadedly connected to the adjusting screw through a lifting plate. An operating wheel is connected to the top of the adjusting screw. The lifting plate is sleeved on the limiting guide rod mounted on the frame through the limiting hole.

[0008] As a preferred embodiment, the seeder includes a housing, with a drive shaft passing through the middle of the housing via a bearing. The seeding disc is mounted on the drive shaft inside the housing and rotates inside the housing via the drive shaft. Multiple seeding chambers are evenly distributed on the seeding disc. The seed inlet at the top of the housing is connected to the seed outlet at the bottom of the seed box via a connecting pipe, and the seed outlet at the bottom of the housing is connected to a seeding tube. Sealing blocks for sealing the seed inlet of the housing are provided around the seeding disc between adjacent seeding chambers. Drive gears are installed at both ends of the drive shaft.

[0009] As a preferred embodiment, the drive mechanism includes a drive shaft and a motor. The drive shaft is mounted on the rear end of the frame, and drive gears are mounted on both ends of the drive shaft. The drive gears are connected to the transmission gears via a gear transmission belt, and a motor is connected to one end of the drive shaft.

[0010] As a preferred embodiment, the seed inlet is smaller than the port size of the sowing chamber, and the seed outlet is larger than the port size of the sowing chamber.

[0011] As a preferred embodiment, a traction frame is connected to the front end of the frame.

[0012] As a preferred embodiment, the inside of the seed box is divided into seed cavities for storing different seeds by partitions.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention connects a traction frame to a traction machine head to guide a row seeder across the land. A furrow opener, which allows for easy adjustment of furrow spacing and depth, first creates furrows in the land. Furrowing can be adjusted according to the planting density and depth requirements of different crops, improving crop production and output. The drive mechanism rotates the seeding disc inside the seeder. When the seeding chamber aligns with the seed inlet, seeds enter; conversely, sealing blocks around the seeding disc block the seed inlet of the outer shell, preventing seeds from entering and facilitating quantitative seeding. When the seeding disc rotates until the seeding chamber aligns with the seed outlet at the bottom of the outer shell, the seeds slide down from the seed outlet along the seeding tube into the furrows created by the furrow opener. Finally, the soil-covering roller at the rear of the frame re-covers and flattens the furrows, thus enabling continuous and quantitative uniform seeding. Attached Figure Description

[0035] In this embodiment, the seeder 5 includes a housing 51. A drive shaft 54 ​​passes through the middle of the housing 51 via a bearing 53. A seeding disc 52 is mounted on the drive shaft 54 ​​inside the housing 51. The seeding disc 52 rotates inside the housing 51 via the drive shaft 54. Multiple seeding chambers 55 are evenly distributed on the seeding disc 52. The seed inlet at the top of the housing 51 is connected to the seed outlet 41 at the bottom of the seed box 4 via a connecting pipe 58. A seed outlet 57 at the bottom of the housing 51 is connected to a seeding tube 59. Sealing blocks 56 for sealing the seed inlet of the housing 51 are provided around the seeding disc 52 between adjacent seeding chambers 55. Drive gears 65 are installed at both ends of the drive shaft 54. The bottom of the seed box 4 is connected to... Several seeders 5 are provided. As needed, the connecting pipes 58 connected to several of the seeders 5 are opened, and the seeds enter the seeding chamber 55 through the seed outlet 41 and the connecting pipes 58. As the motor 62 on the drive mechanism 6 drives the drive shaft 61 to rotate, the drive shaft 61 drives the seeding disc 52 to rotate inside the outer shell 51 of the seeder 5 through the drive gear 63 and the gear transmission belt 64 and the transmission gear 65. During the rotation of the seeding disc 52, when the seeding chamber 55 is aligned with the seed inlet at the top of the outer shell 51, the seeds enter the seeding chamber 55. When the seeding chamber 55 is not aligned with the seed inlet of the outer shell 51, the sealing blocks 56 on the periphery of the seeding disc 52 are used to seal the seed inlet of the outer shell 51 to prevent the seeds from entering the outer shell 1.

[0036] In this embodiment, the drive mechanism 6 includes a drive shaft 61 and a motor 62. The drive shaft 61 is mounted on the rear end of the frame 1. Drive gears 63 are mounted on both ends of the drive shaft 61. The drive gears 63 are connected to the transmission gears 65 through the gear transmission belt 64. The motor 62 is connected to one end of the drive shaft 61.

[0037] In this embodiment, the seed inlet is smaller than the port size of the sowing chamber 55, and the seed outlet 57 is larger than the port size of the sowing chamber 55; this facilitates the entry and exit of seeds.

[0038] In this embodiment, a traction frame 11 is connected to the front end of the frame 1; the machine is connected to the traction head of the agricultural machinery through the traction frame 11.

[0039] In this embodiment, the inside of the seed box 4 is divided into seed chambers for storing different seeds by a partition 42; two different crops can be sown alternately according to sowing needs.

[0040] The working principle and usage process of this utility model are as follows: When using this utility model, the operator slides the furrow opener 2 on the mounting rod 32 through the mounting sleeve 21 to adjust the distance between the furrow openers 2, and fixes it to the mounting rod 32 using the fastening screw 22; this allows the distance between the furrows to be adjusted according to the density of crop growth; rotating the operating wheel 36 rotates the adjusting screw 35, which drives the lifting plate 33 to move up and down, thereby adjusting the height of the furrow opener frame 31 and adjusting the depth of the furrow.
