[0041] In order to guarantee the stability of the operation of the device and the convenience of use, in the embodiment, it is realized by the frame 1, and specifically, as Figure 3 , Figure 5As shown, in frame 1, the horizontal support 1-1 is composed of the first horizontal support 1-1-1 and the second horizontal support 1-1-2; the vertical frame 1-2 is composed of the first vertical frame 1-2-1 and the second vertical frame 1-2-2; the base frame 1-3 is located at the bottom of the entire frame, and the first vertical frame 1-2-1 and the second vertical frame 1-2-2 are symmetrically installed along the center of the base frame 1-3. The first horizontal support 1-1-1 and the second horizontal support 1-1-2 are located between the first vertical frame 1-2-1 and the second vertical frame 1-2-2; the first horizontal support 1-1-1 is located above the second horizontal support 1-1-2, and the two are parallel to each other.

[0042] To ensure that seeds are collected evenly and guided into the sowing rows, thereby precisely controlling seed distribution and sowing accuracy, this embodiment achieves this by setting up a conveying unit 2. Specifically, as shown in the example... Figure 2 As shown, the conveying unit 2 consists of a seed inlet 2-1, a seed retaining cylinder 2-2, a seed dividing head 2-3, a rotating shaft 2-4, a flexible hose 2-5, a seed dividing grid 2-6, a seed dividing grid disc 2-7, and a conveying cover 2-8. The seed dividing grid disc 2-7 is fixedly connected to the frame. The seed retaining cylinder 2-2 is fitted over the outside of the seed dividing grid disc 2-7. The seed inlet 2-1 is located on top of and communicates with the seed retaining cylinder 2-2. The seed dividing head 2-3 is fixedly connected to the rotor 3-4 of the seed-spinning motor 3-3 and is located directly below the seed inlet 2-1, rotating with the seed-spinning motor 3-3. The seed dividing grid 2-6 is arranged along the circumference of the seed dividing grid disc 2-7. The upper end of the flexible hose 2-5 communicates with the seed dividing grid 2-6, and the lower end communicates with the through hole 1-3-1. The conveying cover 2-8 is fixedly connected to the inner ring of the seed dividing grid.

[0043] To provide stable and controllable power to the conveying unit 2 for an automated, uniform, and efficient wheat seed sowing process, this embodiment employs a power unit 3. Specifically, as shown in the example... Figure 3 , Figure 5 As shown, the power unit 3 consists of a power supply 3-1, a power cord 3-2, and a seed-spinning motor 3-3. The power supply 3-1 is mounted on the second horizontal support 1-1-2, and the seed-spinning motor 3-3 is mounted on the first horizontal support 1-1-1. The power supply 3-1 is connected to the seed-spinning motor 3-3 via the power cord 3-2. After the power unit 3 is turned on, the conveying unit 2 operates accordingly. The seeds pass through the conveying unit 2, reach the base frame 1-3, and finally fall into the target sowing row.

[0044] Example 2

[0045] To ensure that seeds are sown at a uniform spacing and density, thereby improving sowing accuracy and crop growth quality, this embodiment achieves this by setting through holes 1-3-1, specifically, as follows: Figure 3 As shown, the base frame 1-3 is provided with through holes 1-3-1 at even intervals, and the number of through holes 1-3-1 is 24.

[0046] To ensure that the seeds are effectively and evenly thrown towards the seed-retaining cylinder 2-2 by centrifugal force, this embodiment achieves this by setting a seed-distributing head 2-3 and a baffle 2-3-1. Specifically, as follows... Figure 2 As shown, the seeding head 2-3 is a thin disc-type part, with baffles 2-3-1 evenly distributed on its surface, and there are 8 baffles 2-3-1.

[0047] To ensure that the seeds are smoothly flung outwards by the seeding heads 2-3 and slide stably down the slope into the seeding grids 2-6, this embodiment uses a conveyor cover 2-8. Specifically, as shown... Figure 2 As shown, the conveyor cover is fixed on the seeding grid 2-7, and the rotating shaft 2-4 passes through the upper and lower bottom surfaces of the conveyor cover 2-8 and is rotatably connected to the seeding head 2-3. The conveyor cover 2-8 is an isosceles frustum structure, and the side angle of the frustum is 60°.

[0048] To facilitate cleaning and maintenance of the device and ensure stable operation of the entire device, this embodiment achieves this through the cooperation of the seed-blocking cylinder 2-2 and the seed-dividing grid plate 2-7. Specifically, as follows... Figure 1 As shown, the seed retaining cylinder 2-2 and the seed dividing plate 2-7 are in a clearance fit.

[0049] To ensure consistent seed distribution and achieve uniform sowing, this embodiment controls the number of seed dividers 2-6, flexible tubes 2-5, and through holes 1-3-1. Specifically, as follows... Figure 1 As shown, the number of seed cells 2-6, hoses 2-5, and through holes 1-3-1 are the same.

[0050] The conveyor cover is fixed on the seeding grid 2-7, and the rotating shaft passes through the upper and lower bottom surfaces of the conveyor cover 2-8 and is rotatably connected to the seeding head 2-3.

[0051] To facilitate user movement of the device and enhance its convenience and stability, this embodiment achieves this by providing a carrying handle 1-4 and support legs 1-5. Specifically, as follows... Figure 3 As shown, the upright frame 1-2 is provided with handles 1-4 on both sides; the base frame 1-3 is provided with legs 1-5 on both sides of the bottom surface.

[0052] To facilitate real-time monitoring of seed flow and distribution, and to ensure visibility and continuity during the sowing process, this embodiment utilizes a structure consisting of a seed-blocking cylinder 2-2 and a flexible tube 2-5. Specifically, as shown... Figure 2 As shown, the seed retaining cylinder 2-2 and the flexible tube 2-5 have transparent structures.

[0053] like Figures 1-5 As shown, the method of using a portable wheat row-planting device is as follows:

[0054] Turn on the power switch to start the seed-distributing motor. The motor will drive the seed-distributing head to rotate at a constant speed. Then, pour the pre-prepared wheat seeds into the seed inlet. The seeds fall from the inlet onto the rotating seed-distributing head, are flung outwards by centrifugal force, collide with the transparent seed-retaining cylinder, and then bounce back to the conveyor cover, finally falling evenly into the seed-distributing grids in the seed-distributing tray. The seeds then fall evenly through the transparent flexible tubes connected to the seed-distributing grids into the through-holes on the base frame, entering the sowing rows.

[0055] When operating this device, one person moves the seeder to ensure it follows the predetermined planting rows. Another person monitors the seed dispensing and replenishes seeds as needed. Once one row is completed, move the seeder to the next row and repeat the process. After use, simply turn off the power.
