[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0026] See also Figure 1-3 The utility model discloses a two-row light corn seeder, which comprises a supporting mechanism and a transmission mechanism, wherein the transmission mechanism is arranged on the supporting mechanism.

[0027] In this embodiment, the support mechanism includes a support frame 1, and fixed gear groups 2 are fixedly installed on the left and right sides of the front end of the support frame 1. The top of the outer wall of the fixed gear group 2 is rotatably connected to a connecting rod 3. A drive assembly box 4 is provided on the top of the two connecting rods 3, and a transmission gear 5 is rotatably connected to the outer wall of the drive assembly box 4 and the connecting rod 3.

[0028] It should be noted that the support frame 1 serves as the main structure of the entire seeder, supporting and connecting all other components, providing a solid foundation, and ensuring the stability and reliability of the seeder during operation. The fixed gear set 2 cooperates with the connecting rod 3 and the transmission gear 5 to transmit the power of the drive assembly box 4 to the transmission mechanism and other related components, realizing effective power transmission and conversion, and providing power guarantee for the normal operation of the seeder. The drive assembly box 4 serves as the power source of the seeder, providing the necessary driving force, and providing a stable and continuous power output for the entire seeder, ensuring the smooth progress of the sowing operation. The transmission gear 5 cooperates with the fixed gear set 2 to realize power transmission and speed adjustment.

[0029] In this embodiment, the transmission mechanism includes a first transmission rod 6 and a second transmission rod 7 installed between two fixed gear sets 2. A double parallel three-link rod 8 is fixedly installed at the front end of the fixed gear set 2.

[0030] It should be noted that the first transmission rod 6 and the second transmission rod 7 connect the two fixed gear sets 2 and transmit power to the first furrowing wheel 10 and other components, ensuring the continuous transmission of power inside the seeder, providing necessary power support for operations such as furrowing and sowing. The double parallel three-link rod 8 connects the support frame 1 and the second furrowing wheel 17 and other components to achieve adjustment and stabilization of the sowing depth. By adjusting the angle and length of the double parallel three-link rod 8 to change the force of the adjustment spring 16, precise control of the sowing depth can be achieved, thereby improving the accuracy and uniformity of sowing.

[0031] In this embodiment, the middle of the left and right outer walls of the support frame 1 are both rotatably connected to the ground wheels 9, and the middle of the left and right inner walls of the support frame 1 are both rotatably connected to the first trenching wheel 10 and the depth limiting wheel 11.

[0032] It should be noted that the ground wheel 9 supports the seed drill and guides it forward. At the same time, it is connected to the fixed gear group 2 through the chain group 12 to provide power for the ground wheel 9. The first furrowing wheel 10 is used to open a sowing furrow in the soil, and the depth limiting wheel 11 is used to control the sowing depth, realizing the dual functions of furrowing and depth limiting, ensuring that the depth and width of the sowing furrow meet the requirements and improving the sowing quality.

[0033] In this embodiment, a chain set 12 is sleeved between the fixed gear set 2 and the ground wheel 9 , and a circle of chain set 12 is also provided between the first ditching wheel 10 and the depth limiting wheel 11 .

[0034] It should be noted that the chain group 12 connects the fixed gear group 2, the ground wheel 9, the first trenching wheel 10 and the depth limiting wheel 11 and other components to achieve power transmission and coordination, ensure the coordinated operation and continuity of power transmission between the various components, and improve the overall performance and efficiency of the seeder.

[0035] In this embodiment, the second transmission rod 7 passes through the two first ditching wheels 10, and the left and right sides of the rear end of the support frame 1 are rotatably connected to the pressure wheels 13.

[0036] It should be noted that the pressing wheel 13 compacts the soil after sowing to ensure close contact between the seeds and the soil, thereby improving the germination rate and survival rate of the seeds and contributing to the healthy growth of crops.

[0037] In this embodiment, brackets are fixedly installed on both left and right ends of the top of the support frame 1, seed storage boxes 14 are fixedly installed on the top of the brackets, and pedals 15 are fixedly installed on the outer walls of the double parallel three-link rods 8.

[0038] It should be noted that the seed storage box 14 facilitates the storage and management of seeds, while ensuring the continuous delivery and uniform distribution of seeds. The pedal 15 provides a stepping platform for the operator to facilitate the adjustment of the state of the seed drill and the operation.

[0039] In this embodiment, an adjustment spring 16 is installed in the middle of the double parallel three-link rod 8, and the bottom of the double parallel three-link rod 8 is rotatably connected to the second groove opening wheel 17, and the adjustment spring 16 is set on the top of the second groove opening wheel 17.

[0040] It should be noted that the second furrowing wheel 17 pre-treats the soil before handing it over to the first furrowing wheel 10 at the rear for secondary furrowing, which improves the quality and efficiency of the furrowing operation and provides good soil conditions for subsequent sowing operations.

[0041] Working principle: Pour an appropriate amount of seeds into the seed storage box 14 to ensure that the seeds can be continuously released, adjust the angle and length of the double parallel three-link rod 8, set the required sowing depth by changing the force of the adjustment spring 16, start the drive assembly box 4, and start the seeder to run, observe the rotation of the ground wheel 9 to ensure that the seeder can move forward smoothly, check the furrowing effect of the first furrowing wheel 10 and the second furrowing wheel 17, and ensure that the depth and width of the sowing furrow meet the requirements. As the seeder moves forward, the first furrowing wheel 10 and the second furrowing wheel 17 will perform furrowing operations on the soil in turn, and the seeds will be continuously released from the seed storage box 14 and fall into the opened sowing furrow through the sowing mechanism. The pressure wheel 13 compacts the soil after sowing to ensure that the seeds are in close contact with the soil. When the seeder reaches the end of the farmland, the drive assembly box 4 is closed to stop the seeder.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
