Variable-speed transverse box movement double-spiral shaft of pot seedling transplanting machine

Abstract

The invention relates to a variable-speed transverse box movement double-spiral shaft of a pot seedling transplanting machine, and belongs to the field of agricultural machinery. Two groups of spiral grooves with reverse spiral directions, equivalent pitches, continuity and same width are formed on the surface of a shaft body, the difference between phase angles of the two groups of the spiral grooves is 180 degrees, the two groups of the spiral grooves are in head-to-tail connection, the smooth transition is formed at the joint, and the spiral line of each group of the spiral groove can form a rotated half-cycle variable trigonometric function curve, a parabola or a double-curve periodic curve after expansion. The variable-speed transverse box movement double-spiral shaft disclosed by the invention can realize the purposes of reducing the box movement speed and reducing the box movement quantity when a transplanting mechanical part of the transplanting machine is used for taking a seedling plate from a seedling pot, as well as accelerating the box movement speed and increasing the box movement quantity after the seedling plate is taken out, further improve the success rate of taking out the seedling plate, and reduce the damage to the seedling plate.

Description

technical field [0001] The invention belongs to agricultural machinery, and in particular relates to a pot seedling transplanting machine with double helical shafts with variable speed and horizontal moving box. Background technique [0002] At present, in the field of transplanting machines, there are mainly four methods of large-scale electromechanical-hydraulic integrated control transplanting, rotary transplanting, semi-automatic transplanting, and manual transplanting. Among them, the large-scale electro-hydraulic integrated control machinery has complex structure and high cost; the semi-automatic transplanting machine is a relatively common transplanting method at present, but its labor intensity is still relatively high; and the rotary transplanting machine combines dexterity and low labor Strength, low cost, etc., but the process of the rotary transplanter entering the pot or clamping the seedlings should stably remove the pot seedlings from the pot, and it is necess...
