[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] Example: Figure 1-4 As shown, this utility model provides a technical solution, an electric drive pneumatic seed suction box seed metering device connection structure, including a seed box 1, and a bottom three-dimensional connection mechanism 2 is provided at the bottom of the seed box 1;

[0033] The bottom three-dimensional connecting mechanism 2 includes a seed metering box 201, a connecting rib plate 202, a connecting plate 203, a connecting corner hole 204, a connecting side hole 205, and a supporting spacer column 206;

Connecting bolts are installed through the interior of the machine. The connecting plate 203 is installed on the top of the seed metering box 201 through the connecting rib plate 202. Then, the connecting corner hole 204 and the connecting side hole 205 are aligned with the bottom of the seed box 1. The bolts are then used to engage with the connecting corner hole 204 and the connecting side hole 205 to achieve initial fixation between the seed metering box 201 and the connecting rib plate 202. Then, the gap at the top of the connecting side hole 205 is filled by the supporting spacer column 206, which effectively improves the stability of the connection between the seed metering box 201 and the seed box 1. This effectively prevents the seed box 1 and the seed metering box 201 from separating during the sowing process, thus effectively improving the stability of the sowing equipment.

[0035] The seed box 1 is equipped with a side elastic mounting mechanism 3 on its outer side;

[0036] The side elastic mounting mechanism 3 includes a mounting slot 301, a connecting crossbar 302, a mounting side hole 303, a mounting bend 304, a mounting bottom hole 305, a connecting diagonal bar 306, and a connecting diagonal hole 307;

Both ends of the connecting crossbar 302 have mounting side holes 303. One end of each connecting crossbar 302 is fixedly connected to a mounting bend 304. A bottom hole 305 is drilled through the center of the bottom end of the mounting bend 304. The other end of the connecting crossbar 302 is fixedly connected to a connecting diagonal bar 306. A connecting diagonal hole 307 is drilled through one side of the bottom of the connecting diagonal bar 306. The outer side of the connecting crossbar 302 slides tightly against the inner wall of the mounting slot 301. A connecting crossbar is installed through the mounting side hole 303.

The front of the seed box 1 is fixed through the engagement between the connecting oblique rod 306 and the connecting oblique hole 307. This optimizes the installation method of the seed box 1 and improves the stability and convenience of the installation of the seed box 1.

[0038] The outside of the seeding box 1 is equipped with a multi-angle tilting material guiding mechanism 4;

[0039] The multi-angle tilting material guiding mechanism 4 includes a material guiding ramp 401, a material guiding inner ramp 402, a material guiding arc ramp 403, an installation inclined block 404, and a sealing top cover 405;

The bottom of the sealing top cover 405 is fitted with the top opening of the seed box 1. The seed flow is optimized by using the guide slope 401 to guide the seeds on one side of the bottom of the seeding box 1, the guide inner slope 402 to guide the seeds inside the seeding box 1 laterally, and the guide arc slope 403 to guide the seeds on the other side of the bottom of the seeding box 1. The sealing top cover 405 is installed on the top of the seeding box 1 by the installation of the inclined block 404, and the sealing top cover 405 seals the top of the seeding box 1. This optimizes the smoothness of seed flow inside the seeding box 1 and effectively improves the sealing performance of the top of the seeding box 1.

[0041] The working principle and usage process of this utility model are as follows: In actual application, when it is necessary to install the seed metering box 201 to the bottom of the seeding box 1, the connecting plate 203 is installed to the top of the seed metering box 201 through the connecting rib plate 202. Then, the connecting corner hole 204 and the connecting side hole 205 are aligned with each other with the bottom of the seeding box 1. Then, the bolts are used to cooperate with the connecting corner hole 204 and the connecting side hole 205 to achieve the initial fixation between the seed metering box 201 and the connecting rib plate 202.

[0042] Then, the gap at the top of the connecting edge hole 205 is filled by the supporting spacer column 206, which effectively improves the stability of the connection between the seed metering box 201 and the seeding box 1, and effectively avoids the phenomenon of separation between the seeding box 1 and the seed metering box 201 during the seeding process, thereby effectively improving the stability of the seeding equipment.

[0043] When the seed box 1 needs to be installed, the connecting crossbar 302 is snapped onto the side of the seed box 1 through the mounting slot 301. Then, the connecting crossbar 302 is fixedly connected to the seed box 1 through the cooperation between the bolt and the mounting side hole 303. The tail of the seed box 1 is fixed through the cooperation between the mounting bent rod 304 and the mounting bottom hole 305. The front end of the seed box 1 is fixed through the cooperation between the connecting diagonal rod 306 and the connecting diagonal hole 307. This optimizes the installation method of the seed box 1 and improves the stability and convenience of the installation of the seed box 1.

[0044] When it is necessary to assist in the seeding of seeds inside the seeding box 1, the seeds on one side of the bottom of the seeding box 1 are guided by the guide slope 401, the seeds inside the seeding box 1 are guided laterally by the guide inner slope 402, and the seeds on the other side of the bottom of the seeding box 1 are guided by the guide arc slope 403. The sealing top cover 405 is installed on the top of the seeding box 1 by the installation of the inclined block 404, and the top of the seeding box 1 is sealed by the sealing top cover 405. This optimizes the smoothness of seed flow inside the seeding box 1 and effectively improves the sealing performance of the top of the seeding box 1.
