Description

Technical Field

[0001] This invention relates to the field of transplanting machinery technology, specifically to a seedling separation device for a strip-type potted seedling transplanter for heading vegetables. Background Technology

[0002] Currently, most commonly used transplanting machinery is semi-automatic. The process requires manual sorting, arrangement, and feeding of seedlings, resulting in high labor intensity and a low operating speed of only about one seedling per second, leading to low efficiency and high operating costs. Due to significant differences in the characteristics and transplanting agronomical requirements of different crop varieties, existing transplanting machinery is often highly specialized and has poor general applicability. The mechanization and automation levels in the transplanting of heading vegetables remain low, severely restricting the improvement of production efficiency and quality in this field.

[0003] CN206078057U discloses an adjustable seedling separation mechanism for a single-row paper pot seedling transplanter, which uses a disc cutter to cut the single-row paper pot seedlings to achieve the seedling separation function; however, in the technology disclosed in this patent, the disc cutter is set directly above the end of the pot running channel. When the seedlings of heading vegetables grow to a suitable size for transplanting, the seedling leaves are large and spread out, and the movement trajectory of the disc cutter will damage the seedlings of heading vegetables.

[0004] CN110447361A discloses a chain-type paper pot transplanter and its usage method. During transplanting, a paper connector is pulled out from the seedling tray, and then the folded connecting paper strips between the seedling pots are sequentially stretched to form a chain of seedling pots connected by these paper strips. Guided by a seedling pot straightening guide plate, the chain of seedling pots slides into the transplanting trough and falls into the prepared seedbed. This patented technology can be used for transplanting crops with a plant spacing equal to the length of the connecting paper strips between the seedlings and small seedling weight, such as scallions. When the planting spacing of crops is greater than the length of the connecting paper strip between the seedlings, the lack of a seedling separation device in the technology disclosed in this patent limits the planting spacing of the seedlings, making it impossible to transplant them according to the agronomic requirements. The transplanter disclosed in this patent lacks a device or structure for actively controlling the speed of transporting the seedlings, making it impossible to control the planting spacing after separation. When the seedlings are heavy, such as the seedlings of heading vegetables, their own weight and inertia are large, and the friction between the seedlings and the device is also large, which can lead to excessive tension on the seedlings during transplanting, resulting in unpredictable damage to the seedling pots.

[0005] When transplanters operate in the field, vibrations caused by the terrain, surface conditions, and the tractor itself can alter the posture of the seedlings, affecting successful transplanting. The technologies disclosed in the two patents, which use tracks or vertical baffles to straighten the seedlings, are insufficient to guarantee a proper seedling posture. Summary of the Invention

[0006] The purpose of this invention is to provide a seedling separation device for a seedling transplanter of heady vegetables, which solves the problems of seedling damage caused by the seedling separation device and poor seedling posture caused by the vibration of the transplanter in the prior art.
