[0002] The seed meter is an important component of the seeder. There are many types of existing dryland crop seed meters, which can be divided into precision and semi-precision types based on the number of seeds planted, and can be divided into socket type, groove wheel type, air suction type, etc. based on the structural principle. However, most of the existing seed meters are single-port seeding, and due to their structural limitations, they cannot meet the requirements of coaxial small-pitch seeding. Utility Model Content

[0003] The utility model provides a spoon-type double-chamber 36-clamp one-hole multi-plant precision sowing and metering device, wherein two seed guide chambers are used to sow seeds through respective sowing ports, thereby realizing the precision sowing requirement of double rows and equal distances.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spoon-type double-bin 36-clamp one-hole multi-plant precision sowing seed meter, which includes: a middle shell, wherein the two opposite sides of the middle shell are respectively provided with a seed guide chamber, and a main shaft running through the center of the two seed guide chambers, wherein the main shaft cooperates with the middle shell through a bearing, and the bottom of each seed guide chamber is respectively provided with a sowing port; a seed guide disc, wherein the seed guide disc is respectively arranged in the corresponding seed guide chamber and cooperates with the main shaft, and the outer edge of each seed guide disc is respectively provided with 18 seed guide grooves in a circumferential direction; a spoon disc, wherein the spoon disc is arranged in pairs and is respectively fixedly connected to the outer side of each seed guide disc, and each A truncated cone is provided on one side of the spoon plate corresponding to the seed guide plate, and 18 seed scoops are provided circumferentially of the spoon plate, and each seed scoop corresponds to the seed guide groove one by one; an isolation ring, the isolation rings are arranged in pairs and are respectively sleeved on the corresponding truncated cone, each isolation ring isolates the seed guide groove and the seed scoop, and the isolation ring is provided with a seed guide window corresponding to the top of the middle shell; an outer cover, the outer covers are arranged in pairs and respectively close the corresponding seed guide chambers, and a feed hopper is provided on the outer side wall of each outer cover, a feed port is provided at the bottom of the feed hopper, and the main shaft passes through one of the outer covers and extends to the outside.

[0005] Preferably, the edge ring of the isolation ring corresponding to one side of the outer cover is circumferentially provided with a concentric groove, and the edge of the seed scoop is adapted to the concentric groove.

[0006] Preferably, each of the seed guide chambers is provided with an adjustment groove along the circumferential direction on the outer side, and the isolation ring is provided with a positioning adjustment arm extending to the outside of the seed guide chamber through the adjustment groove.

[0007] Preferably, a brush is provided on the top of each outer cover corresponding to the seed guide window.

[0008] The beneficial effects of the utility model are as follows: the main shaft is used to connect the power device to drive the two seed guide discs and their respective spoon discs to rotate. During the sowing process, the seeds enter the seed guide chamber through the feed hopper, and the rotating seed scoop scoops up the seeds until they reach the seed guide window. The seeds fall into the corresponding seed guide groove through the seed guide window and continue to rotate with the seed guide disc until they are discharged through the sowing port to complete the sowing operation. The two seed guide chambers sow seeds through their respective sowing ports, respectively, so as to achieve the double-row equidistant precision seeding requirements. The concentric grooves are used to constrain the seeds scooped up by the seed scoop, so as to avoid too many seeds being scooped up or failing to accurately enter the seed guide window. By changing the position of the positioning adjustment arm, the isolation ring is driven to rotate, thereby changing the position of the seed guide window to achieve different sowing requirements. The brush cleans the smaller seeds to ensure that the seeds can correctly enter the seed guide window. BRIEF DESCRIPTION OF THE DRAWINGS
