Ejection and seedling fetching device of vegetable pot seedling transplanting machine

Abstract

The invention discloses an ejection and seedling fetching device of a vegetable pot seedling transplanting machine. An existing rotary seedling fetching mechanism of the vegetable pot seedling transplanting machine often adopts a pulling-out type seedling fetching way that a seedling fetching claw is inserted into pot soil for clamping and fetching a seedling or directly clamping and fetching the rootstalks of seedlings, so that the root systems of the seedlings and the soil structure of pot soil are easily injured and a certain growth recovery period is required for the seedlings. The ejection and seedling fetching device disclosed by the invention comprises a cam swing link component, an ejection rod support component, an ejection rod component, a flexible cable transmission component and a rotary seedling fetching mechanism, wherein the cam swing link component inputs power, transmits part of the power to the ejection rod component through the flexible cable transmission component and transmits the other power to the rotary seedling fetching mechanism through a variable speed transmission mechanism; the ejection rod support component is fixed on a rack and supports the ejection rod component; and the rotary seedling fetching mechanism fetches out the pot seedlings in a seedling tray while the ejection rod component ejects the pot seedlings. The ejection and seedling fetching device disclosed by the invention is in the seedling fetching way of firstly ejecting the pot seedlings from the seedling tray by the ejection rod component and further clamping and fetching the pot soil by the rotary seedling fetching mechanism, and the seedlings are prevented from being injured.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a device for picking seedlings, in particular to a device for ejecting seedlings from a vegetable pot seedling transplanter. Background technique [0002] Pot seedling transplanting technology is a modern agricultural production increase measure. Seedling cultivation and transplanting have good effects on resisting drought, cold, salinity, pests and diseases, etc., ensuring that the seedlings are complete, uniform, uniform and strong, and shortening the field production period, especially Multi-crop planting is of great significance to increase the yield per unit area and develop high-yield and efficient agriculture. [0003] The existing vegetable pot seedling transplanting machine rotary seedling picking mechanism often adopts the pull-out seedling picking method of inserting the seedling claws into the pot soil to pick up the seedlings or directly clamping the roots and ste...

AI Technical Summary

Problems solved by technology

[0003] The existing vegetable pot seedling transplanting machine rotary seedling picking mechanism often adopts the pull-out seedling picking method of inserting the seedling claws into the pot soil to pick up the seedlings or directly clamping the roots and stems of the seedlings, which is easy to damage the root system of the seedlings and the pot soil. Soil structure, so that seedlings need a certain growth recovery period
