It should be understood that the following text is intended to describe only one or more specific embodiments of the utility model and does not limit the scope of the utility model strictly as claimed.

As shown in fig. 1-6, embodiments of the present utility model provide a seed metering device that is designed to improve seed efficiency and precision while reducing labor intensity. The main component of the seed metering mechanism 1 is a storage bin 11, wherein a material shoveling part 112 is fixedly connected to the inner side wall of the storage bin 11 and is used for shoveling and throwing seeds in the running process of the device. The outside of the storage bin 11 is penetrated with a plugging through groove 111, a blanking pipe 12 is inserted into the plugging through groove 111, one end of the blanking pipe 12 is provided with an expanding opening 121 (as shown in fig. 2-3), and seeds can be smoothly discharged through the expanding opening 121 after being scooped up and fall into the ground through the blanking pipe 12.

The side surface of the storage bin 11 of the seed metering mechanism 1 is fixedly connected with a hatch 13 for preventing seeds from splashing or losing in the moving process. The side of hatch 13 and the one end of storage silo 11 are all fixedly connected with location axle 14, and the one end of location axle 14 is connected with gyro wheel 2 for equipment can be on subaerial steady removal.

The driving shaft 22 is positioned at the center of the side surface of the roller 2, and the scraping assembly 3 and the traction frame 4 are rotatably connected to the driving shaft 22. When the roller 2 rotates, the driving shaft 22 drives the scraping assembly 3 and the traction frame 4 to move together. Wherein the scraping assembly 3 comprises a scraping plate 31, and the scraping plate 31 can carry out scraping treatment on the ground after seed sowing, so that seeds are scattered in the soil more uniformly.

The traction frame 4 includes a cross bar 41 and second pulling plates 42 fixed to both ends of the cross bar 41. The lower end surface of the second pulling plate 42 is fixedly connected with a plough claw 43, and when the seed metering device moves, the plough claw 43 can plough a gully, so that seeds can be sowed to the soil depth suitable for growth. In addition, in order to improve stability and anti-slip property of the device, anti-slip grooves 21 are formed in the outer side of the roller 2, and the anti-slip grooves 21 are distributed at equal intervals around the central axis of the roller 2.

The working principle of the utility model is as follows:

1. the user first needs to add seeds into the interior of the discharge tube 12 through the expansion port 121, and finally the seeds fall into the storage bin 11.

2. When the roller 2 rotates, the driving shaft 22 and the positioning shaft 14 cooperate to drive the storage bin 11 to synchronously rotate.

3. When the storage bin 11 rotates, the shoveling member 112 contacts and scoops up seeds in the storage bin 11.

4. As the shovel 112 moves to a high position, the seeds on the shovel 112 slide down due to the gravity, and the sliding seeds fall into the discharging tube 12 and are discharged through the expansion opening 121.

5. During movement, the plow claw 43 plows the ground into the ravines, and the seeds discharged from the expansion port 121 fall into the ravines.

6. The scraper 31 is provided to smooth the ravines where the seeds are scattered, so that the seeds are scattered more uniformly in the soil.

The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
