Problems solved by technology

The brush is easy to wear when the air pressure is low, and the seed cleaning sheet and the meshing toothed wheel rely on extrusion and sliding cutting to clear the seeds, and the depth of pressure feeding is limited, so it is easy to scratch the seeds when sowing the viscous seeds The seeds in the wheel cannot be removed, resulting in knocking and missed sowing

Embodiment Construction

[0024] Below in conjunction with the embodiment shown in accompanying drawing, further illustrate specific content of the present invention and working process thereof.

[0025] The inner side of the seed wheel 11 has a seed cleaning groove connected with the bottom of the hole. The through hole formed by the seed cleaning groove and the hole forms a diversion channel to guide the seed filling, which can speed up the seed filling process and improve the working speed of the seed meter. Finally, the local swirling airflow formed above the hole can bring out the redundant seeds in the hole to complete automatic seed cleaning. The seed clearing spring 14 is installed on the seed meter cover 2 through the fixed shaft 16 and the adjusting shaft 13, and engages with the through hole at the bottom of the seed clearing groove and the hole. During the seeding process, the seed clearing spring 14 pushes the seeds that do not automatically fall out of the hole from the through hole at th...

Abstract

The invention relates to a universal blowing-type precision seed-metering device for soy beans and corn, which belongs to an agricultural machine. The universal pneumatic precision seed-metering device for the soy beans and the corn comprises a seed shell (1), an inoculated tube (5), an upper cover (6), a seed cleaner (10), a seed wheel (11) and a seed tube (15). The universal pneumatic precision seed-metering device for the soy beans and the corn is characterized in that: the seed wheel (11) is arranged in the seed shell (1); an inner side of the seed wheel (11) is provided with a seed cleaning groove communicated with the bottom of a shaped hole; the top of the upper cover (6) is provided with the inoculated tube (5) and a seed guide plate (7); the seed guide plate (7) is positioned above the seed wheel (11); a front end and the top of the upper cover (6) are provided with blowing nozzle mounting holes; a blowing nozzle (3) is arranged in one of the mounting holes and the other blowing nozzle mounting hole is sealed by a cover board (4); and a seed-metering device cover (2) is provided with a seed cleaning mechanism. The seed-metering device can overcome the defects of sowing leakage and seed blocking of the blowing-type seed-metering device and improve the universality of the seed-metering device.

Description

technical field [0001] The invention belongs to agricultural machinery and relates to a universal pneumatic seed metering device for soybeans and corns. Background technique [0002] The air blowing seed meter is a high-efficiency and precise seed metering component. How to remove the redundant seeds in the hole during the seed filling process and the seeds that are not discharged from the hole during the seeding process are the main factors affecting the seed metering performance. In order to solve the problems such as seed knocking and missing seeding in the work of the seed metering device, a brush, a seed cleaning sheet and a meshing toothed wheel have been used to clean the seeds in the past. The brush is easy to wear when the air pressure is low, and the seed cleaning sheet and the meshing toothed wheel rely on extrusion and sliding cutting to clear the seeds, and the depth of pressure feeding is limited, so it is easy to scratch the seeds when sowing the viscous seeds...
