Abstract

The invention discloses a double-disk type automatic reseeding metering device, which relates to the technical field of agricultural machinery. The invention includes a frame, on which there are internally filled seeding discs and spoon-clip re-seeding discs which can be rotated in opposite directions. A number of variable-volume holes are set in the direction. In the seed-discharging work area, the volume of the hole decreases with the rotation of the seed-discharging disc, so that the type holes receive the seed grains put in the seed inlet in the seed-discharging work area and flow toward the seed-discharging area. Compulsory seeding at the seed opening; the re-seeding disc is provided with at least two scoop clips that can hold and release seeds along its circumference, and the scoop clips of the re-seeding disc hold the seeds put in the seed inlet and cooperate with the seeding disc to discharge seeds Oral supplementation. When there is a cavity in the hole of the seed metering disc, the reseeding disc can reseed in real time, thereby improving the reseeding accuracy and working stability of the seed metering device.

Description

technical field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a double-disc automatic reseeding device. Background technique

[0002] Precision sowing has many advantages such as seed saving, high yield, and economy. However, due to the limitation of the design of the seeding system and the conditions of use, the phenomenon of missing seeding inevitably occurs in the sowing operation. If artificial replanting or manual transplanting is performed at the missed sowing position after emergence, the growth will not be able to grow normally due to growth differences. Therefore, it is necessary to use a missed sowing and reseeding device to automatically replant with high quality when sowing. Until today, many scholars have carried out research on this. conducted research and achieved objective results.

Embodiment Construction

[0038] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0039] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0040] The double-disc type automatic reseeding device disclosed in this embodiment includes a frame 100, on which a rotatable seeding disk 200 and a reseeding disk 300 are arranged, and the reseeding disk 300 is eccentrically arranged in a hollow seeding table. In the disk 200, and the reseeding disk 300 and the seeding disk 200 rotate in opposite directions. There are a number of holes 220 whose volumes change with the rotation of the seeding disk 200. The hole 220...
