[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1As shown, in embodiment 1, a connector for connecting a seed box and a seed metering device comprises a transition piece 1 and a connector 2, wherein a seed box is disposed on the transition piece, the seed box is connected to the transition piece by plugging, and the seed metering device connector is connected to the seed metering device by bolts below the transition piece, and the seed metering device connector is connected to the seed metering device as a whole by bolts. The transition piece 1 is provided with a plug hole 1-1 for plugging and matching with the seed box 3, and the plug hole matches the shape of the seed box, which can ensure stable plugging with the box body and ensure the sealing of its connection to prevent seed leakage. The seed metering device connector 2 is formed by integral forging of cast aluminum and is connected to the seed metering device as a whole by bolts. The connector 2 comprises a main housing 2-1, and the interior of the main housing 2-1 is hollow to form a seeding channel. In this embodiment, an upper flange 2-2 connected to the transition piece 1 is provided at the upper end of the main housing 2-1 to realize bolted connection between the two. A lower flange 2-3 is provided at the lower end of the main housing 2-1 for connection with the seed metering device. Bolt holes are provided on the upper flange and the lower flange; the outer perspective window 2-4 of the main housing 2-1 is convenient for observing the seed residue. A guide plate 2-5 is provided inside the main housing 2-1 and near the upper seeding port to avoid accumulation and blockage during the seeding process and ensure smooth seeding.

[0019] The bolt holes on the flange of the seed meter connector 2 can be used as pressure plate connection holes. When the seed meter is connected to the seed meter connector 2, the pressure plate can be used to clamp the seed meter first, and then the bolt holes at the bottom of the seed meter connector 2 can be used to fix the seed meter. The advantage of this structure is that it prevents the situation where only the upper and lower connections are ensured when installing the seed meter, while ignoring the close fit between the seed meter connector 2 and the arc surface of the seed meter, thereby affecting the seeding accuracy of the seed meter.

[0020] In this embodiment, the transition piece 1 is a steel plate welded frame or a rubber frame, and is connected to the connector 2 by bolts. The seed box is connected to the transition piece 1 by plugging. The advantage of this structure is that it eliminates the installation error of the upper and lower connections of the transition connector 1, and can maximize the installation accuracy requirements of the seed box and the seed meter, making the entire structure both firm and flexible. At the same time, it is fixedly connected with the connector 2 by bolts to improve the stability of the entire device. If the transition piece is made of rubber material, it can buffer the vibration impact on the seed box caused by uneven terrain during sowing in one step, effectively extending the service life of each component and reducing the user's use and maintenance costs.

[0021] Example 2: Figure 2 , 3 As shown, based on Example 1, this embodiment is optimized as follows: an integrally formed wide-mouthed semicircular cover body 2-6 is provided at the lower part of the main shell 2-1, that is, the semicircular cover body and the main shell are integrally formed, and the semicircular channel of the wide-mouthed semicircular cover body 2-6 is connected to the seeding channel in the main shell 2-1 to ensure smooth seeding.

[0022] In this embodiment, a connecting plate 2-7 is provided at the internal connection between the main housing 2-1 and the semicircular cover 2-6, and a connecting hole 2-8 is provided on the connecting plate. In addition, a connecting block 2-9 is provided at the top of the wide-mouth semicircular cover 2-6 located outside the main housing 2-1, and a connecting hole 2-8 is provided on the connecting block 2-9. The above structural design is designed for the finger-clamping seed metering device and the air-suction seed metering device, so that it is applicable to both seed metering devices, providing the versatility of the connecting body.

[0023] As a preferred solution, the top of the wide-mouthed semicircular cover 2-6 extends into the seeding channel of the main housing 2-1 and corresponds to the guide plate 2-5 up and down. The seeds falling from the guide plate fall on the top of the wide-mouthed semicircular cover 2-6 located in the seeding channel, which slows down the impact of the seeding process and protects the seeds. The guide plate 2-5 is an arc plate or an angle plate, which diverts the seed flow and effectively prevents seed accumulation and blockage; this design can not only reduce the impact damage to the falling seeds caused by the height difference, but also play a diversion role for the falling seeds, avoiding the blocking of the seed metering device inlet due to the adhesion of seeds caused by reasons such as seed moisture, affecting the efficiency of sowing operations. In this embodiment, the seeding channel in the main housing 2-1 includes a slope channel, a vertical channel and a wide-mouth channel that are connected in sequence, and the guide plate 2-5 is located in the vertical channel. The seeds pass through the slope channel, the vertical channel and the wide-mouth channel in sequence to realize the feeding of seeds from the seed box to the seed metering device.

[0024] As a preferred solution, the main housing 2-1 is provided with a connecting ear seat 2-10 to improve the connection stability of the connector. The perspective window 2-4 is a high-strength transparent plastic window or a high-strength transparent glass window, which ensures its own strength and facilitates timely understanding of the seed usage.

[0025] The utility model has a simple structure and a unique appearance. The entire design can ensure that the installation and replacement are convenient and quick, and the entire seeding mechanism can be tightly connected, thereby ensuring the installation precision and matching requirements, greatly saving labor costs and improving seeding efficiency.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
