TECHNICAL FIELD

[0001] The utility model relates to a novel seed metering device support belongs to agricultural machinery technical field. BACKGROUND

[0002] The ridge distance in different regions is mainly affected by local climate conditions, soil types, crop types and agricultural management techniques. If the ridge distance is too large, it cannot be reasonably densely planted. If the ridge distance is too small, it is not resistant to drought and waterlogging, and it is easy to be washed away. In the selection and application of ridge distance in different regions, various factors need to be considered comprehensively, including but not limited to climate conditions, soil types, crop types and agricultural management techniques, to ensure the sustainability and efficiency of agricultural production. At present, in many areas of soybean and corn planting, large-ridge double-row and large-ridge three-row planting modes are promoted, and the planting of wheat adopts wide-narrow row planting mode. Therefore, there are different requirements for the transverse planting distance of the seeding equipment. In particular, within a proper range, reducing the distance of narrow rows can ensure that the plants in large-ridge double-row planting are as much as possible in the middle position of the ridge, avoiding damage to the root system of the crops during the mid-term management process of the crops, such as removing weeds on the ridge or loosening the soil. Therefore, a new type of seed metering device support with adjustable row spacing range and convenient adjustment is needed. SUMMARY

The right-side bracket includes a vertical plate 1, a right-side wing plate 2, a left-side wing plate 3, a right-side lower support pipe 4, a seed metering device mounting plate 5, and a right-side upper support pipe 6. The left-side bracket includes a vertical plate 1, a right-side wing plate 2, a left-side wing plate 3, a seed metering device mounting plate 5, a left-side upper support pipe 7, and a left-side lower support pipe 8.

[0017] The right-side support is characterized by the seed metering device mounting plate 5 being vertically welded symmetrically to the upright plate 1; the right-side lower support pipe 4 passing through the circular hole below the upright plate 1 and being vertically welded together, with its exposed left side portion being smaller than its exposed right side portion; the right-side wing plate 2 and the left-side wing plate 3 being welded to the opposite sides of the upright plate 1, with the circular holes on the right-side wing plate 2 and the left-side wing plate 3 passing through and being welded together, and their lower end planes being perpendicular to the mounting plane of the seed metering device mounting plate 5; and the right-side upper support pipe 6 passing through the circular hole above the upright plate 1 and being vertically welded together, with the right-side upper support pipe 6 being parallel to the right-side lower support pipe 4, and the exposed left side portion of the right-side upper support pipe 6 being smaller than its exposed right side portion.

[0018] The left support is characterized in that the seed metering device mounting plate 5 is vertically welded to the upright plate 1 symmetrically on both sides; the left lower support pipe 8 passes through the circular hole below the upright plate 1 and is vertically welded together, with its right exposed portion being smaller than its left exposed portion; the right wing plate 2 and the left wing plate 3 are welded to the two sides of the upright plate 1 respectively, the circular holes on the right wing plate 2 and the left wing plate 3 pass through the left lower support pipe 8 and are welded together, and their lower end planes are perpendicular to the mounting plane of the seed metering device mounting plate 5; the left upper support pipe 7 passes through the circular hole above the upright plate 1 and is vertically welded together, the left upper support pipe 7 and the left lower support pipe 8 are parallel to each other, and the right exposed portion of the left upper support pipe 7 is smaller than its left exposed portion;
