Description

Seedling raising bowl plate

Technical Field

The utility model relates to a crops cultivation technical field, more specifically relates to a alms bowl dish of growing seedlings for machinery is transplanted.

Background

The seedling tray is an indispensable seedling container for agricultural mechanical transplanting, the seedling separation and seedling taking can be completed by a machine only after crops are grown by using seedling trays with consistent specifications and are transferred to the machine, and the existing rice transplanter and automatic transplanter are basically based on seedling tray seedling culture. The seedling raising plate is generally divided into a flat bottom plate and a pot body plate, the pot body plate enables crop seedlings to obtain independent growth space in the seedling raising stage, roots are not damaged during transplanting and seedling separating, the seedling recovery after transplanting is quicker, the seedling raising effect is better than that of a flat bottom plate, and the flat bottom plate is only used for raising rice seedlings generally.

The existing seedling raising tray is generally made of traditional plastics such as polyethylene, polyvinyl chloride, polystyrene, polypropylene and the like, because the materials are not degradable, when the pot tray is used for raising seedlings, transplanting machinery or manpower is needed to take the seedlings out of the pot of the seedling raising tray, and generally the machinery is complex, the use cost is high, or the mechanization degree is low. Therefore, patent cn201410745578.x proposes a biodegradable seedling raising tray, which realizes the 'reel transplanting' of pots and seedlings together by utilizing the characteristic that biodegradable materials can be degraded in soil, namely, the pots and the trays do not need to be separated after the seedling raising of the biodegradable pot tray, the seedlings are directly cut into blocks and transplanted in a separated mode, the seedlings are not required to be taken out from the pots in an ejection or clamping mode, and therefore, the seedling separating mechanism of a transplanting machine can be simplified. In order to improve the quality of seedling and transplanting, CN201822099715.3 proposes a pot-bowl type biodegradable seedling raising tray suitable for mechanical transplanting, all the pot bodies of the tray are completely connected, the pot tray has a compact structure, but the pot needs to be cut in two directions respectively during seedling separation, so that a single pot seedling can be separated, and because the longitudinal direction and the transverse direction need to be cut simultaneously during transplanting operation, the mutual interference of longitudinal direction cutting devices and transverse direction cutting devices needs to be avoided, and the design and the structure requirements on the longitudinal direction cutting devices and the transverse direction cutting devices are higher; in order to avoid the mutual influence of longitudinal and transverse slitting devices, patent CN201911218375.4 provides a biodegradable seedling raising tray with transverse slits, the transverse slits are reserved on the tray transversely when the pot tray is prepared, only the longitudinal slitting device is needed to longitudinally slit the pots and the pots, the transverse slitting device is not needed, the interference between the longitudinal and transverse sectioning devices can be completely avoided, however, because the internal slitting lines of the tray are too many, if the seedling raising tray with a long seedling raising period is high in degradation degree, the seedling raising tray can be broken due to the tray splitting and the transferring process after seedling raising, and the incomplete operation effect of the transplanter can be directly influenced by the seedling raising tray.
