Detailed Implementation
[0022] The portable, manually driven precision seeder for wheat ears in this embodiment, such as Figure 1-2 As shown, the device includes a storage hopper 2, a metering roller 4, a drive wheel 7, and a transmission wheel 8. The drive wheel 7 is in contact with the ground. A connecting rod 13 is rotatably connected to one end of the metering roller 4. The transmission wheel 8 is installed on the other end of the metering roller 4. The drive wheel 7 is rotatably connected to the other end of the connecting rod 13. The drive wheel 7 and the transmission wheel 8 are connected in a transmission manner. The discharge port of the storage hopper 2 is in contact with the roller surface of the metering roller 4. A metering groove 15 is opened on the roller surface of the metering roller 4. The metering groove 15 corresponds to the position of the discharge port of the storage hopper 2. That is, when the metering roller 4 rotates, it drives the metering groove 15 to pass through the discharge port of the storage hopper 2. Seed particles enter the metering groove 15 through the discharge port of the storage hopper 2. The drive wheel 7 drives the transmission wheel 8 to rotate the metering roller 4. Multiple metering grooves 15 are used to quantitatively separate wheat seeds and sow them, improving the uniformity and efficiency of sowing.
[0023] like Figure 4 As shown, fixed flanges 16 are fixedly connected to both sides of the frame 1. The two ends of the quantitative roller 4 are rotatably connected to the two fixed flanges 16 respectively. A fixed shaft is coaxially fixedly connected inside the quantitative roller 4. The two ends of the fixed shaft are rotatably connected to the two fixed flanges 16 respectively. One end of the fixed shaft passes through one of the fixed flanges 16 and is coaxially fixedly connected to the transmission wheel 8.
[0024] A handrail 6 is fixedly connected to the connecting rod 13. A fixing frame 12 is installed on both ends of the shaft of the drive wheel 7. The end of the fixing frame 12 is fixedly connected to the handrail 6. A feeding hopper 5 is provided directly below the quantitative roller 4. The feeding port area of the feeding hopper 5 is larger than the area of the axial tangent of the quantitative roller 4. The feeding hopper 5 is fixedly connected to the connecting rod 13.
[0025] like Figure 1As shown, a drive sprocket is coaxially fixedly connected to the drive wheel 7, and the transmission wheel 8 is a transmission sprocket. The drive sprocket and the transmission sprocket are connected by a chain 9. The drive wheel 7 is composed of two or more circular pieces with gradually decreasing diameters and coaxially fixedly connected. There is a gap between adjacent circular pieces. The circular pieces are provided with toothed grooves, which are evenly arranged along the circumference of the circular pieces. By setting the drive wheel 7, on the one hand, it can provide the driving force for the rotation of the seeding, and on the other hand, it can ensure a good contact effect with the ground, avoid the situation of asynchronous rotation, and improve the uniformity of seeding.
[0026] like Figure 2-3 As shown, a frame 1 is fixedly connected to the side of the connecting rod 13. A stop block 3 is installed inside the frame 1. The side wall of the stop block 3 is in contact with the side wall of the quantitative roller 4, and the stop block 3 is located in front of the quantitative roller 4 in the rotation direction. An adjusting bolt 14 is provided on the side of the stop block 3 away from the quantitative roller 4. The adjusting bolt 14 is threadedly connected to the frame 1, and the end of the adjusting bolt 14 is pressed against the side wall of the stop block 3.
[0027] like Figure 1-2 As shown, a first fixing rod 10 and a second fixing rod 11 are fixedly connected to both sides of the frame 1. The first fixing rod 10 and the second fixing rod 11 are arranged crosswise and fixedly connected to each other. The side wall of the storage hopper 2 is fixedly connected to the ends of the first fixing rod 10 and the second fixing rod 11.
[0028] Working principle: When in use, hold the handle 6 to make the drive wheel 7 contact the ground, put the seeds into the storage hopper 2, and push the seeder forward. The drive wheel 7 rolls along the ground and drives the transmission wheel 8 to rotate through the chain 9. The transmission wheel 8 drives the quantitative roller 4 to rotate synchronously. When the quantitative roller 4 rotates, the quantitative trough 15 will enter the discharge port of the storage hopper 2. The seeds enter the quantitative trough 15 under the action of gravity. With the rotation of the quantitative roller 4, the seeds in the quantitative trough 15 are moved forward until the quantitative trough 15 flips and the seeds fall into the discharge hopper 5 and fall into the soil through the discharge hopper 5, completing the seeding.
[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
