Plug seedling transplanting machine positioning seedling picking device

Abstract

The invention relates to a locating and seedling-taking device for a tray seedling transplanter. The locating and seedling-taking device comprises a rack, a tray locating rocker, a seedling push rocker, an air tap fixing plate, an air tap, a compression spring, an extension spring A, a chuck holder, a tray, a power switch, an electromagnet, a roller A, a roller B, an extension spring B and an initial limiting switch, wherein the tray locating rocker is hinged with the rack; the seedling push rocker is hinged with the rack; the electromagnet is arranged below the rack; the power switch is electrically connected with the electromagnet; the air tap fixing plate and the side part of the rack are connected with each other through the compression spring; the initial limiting switch is arranged on one side of the tray locating rocker; the chuck holder is arranged outside the side part of the rack; the tray is arranged inside the chuck holder. Aiming at the problem of accurate location of the tray of a blowing-type transplanter, locating, seedling pushing, blowing and seedling taking are achieved by adopting a double-rocker mode, accurate locating of the tray can be finished, meanwhile, the binding power between a pot seedling and the tray can be released, the locating and seedling-taking device is simple in structure, and the seedling blowing accuracy can be ensured.

Description

technical field [0001] The invention relates to a positioning seedling picking device for a hole tray seedling transplanting machine. Background technique [0002] At present, the plug seedling technology has the advantages of labor saving, labor saving, energy saving, easy management and protection of the agricultural ecological environment. It is widely used in the production of vegetables and flowers. In order to ensure that the crops have appropriate space to promote rooting and growth, transplanting is required. For a long time, the transplanting of crops in dry land has been mainly done manually, with high labor intensity and low transplanting efficiency. Automatic transplanting machines have emerged as the times require. The current transplanting machines in my country mainly use manipulators to automatically pick seedlings. The clamping speed is fast and the work is reliable, but the manipulator is easy to cause damage to the seedling stem when clamping the seedlings, ...

[0002] At present, the plug seedling technology has the advantages of labor saving, labor saving, energy saving, easy management and protection of the agricultural ecological environment. It is widely used in the production of vegetables and flowers. In order to ensure that the crops have appropriate space to promote rooting and growth, transplanting is required. For a long time, the transplanting of crops in dry land has been mainly done manually, with high labor intensity and low transplanting efficiency. Automatic transplanting machines have emerged as the times require. The current transplanting machines in my country mainly use manipulators to automatically pick seedlings. The clamping speed is fast and the work is reliable, but the manipulator is easy to cause damage to the seedling stem when clamping the seedlings, which reduces the quality of transplanting; the air blowing transplanter adopts pneumatic seedlings, which causes less damage to the seedling body and the accuracy of the plug tray Positioning is the prerequisite for the smooth operation of the air-blown transplanter. Therefore, the positioning device of the tray is an important part of the air-blown transplanter. The current positioning device has a complicated structure.
