AI Technical Summary
The seedling picking mechanism of existing transplanters uses cylinder transmission, which requires two steps to complete the descent and clamping action, resulting in low work efficiency and increased equipment size and manufacturing cost.
The innovative structure of active and passive sliding tables allows the seedling picking mechanism to complete four actions in one step: lowering, pressing, clamping the seedling pot, and lifting, by moving the active sliding table downwards to block the passive sliding table. Electric drive transmission replaces pneumatic transmission.
It improves work efficiency, reduces equipment size and manufacturing costs, and enhances the stability of seedling trays.

Abstract
Claims
1. A one-step seedling picking mechanism for a transplanter, characterized in that: The system includes an up-and-down transmission assembly (1), on which an active slide (2) is slidably mounted. A passive slide (3) is mounted on the vertical line of the active slide (2). A seedling-picking actuator assembly (4) is mounted on the active slide (2), and a seedling-picking clamp assembly (5) is mounted on the passive slide (3). The up-and-down transmission assembly (1) provides the active slide (2) with the power for linear motion, so that when the active slide (2) moves downward, it abuts against the passive slide (3) to make it move downward passively. The seedling-picking actuator assembly (4) is plugged into the seedling-picking clamp assembly (5) and moves together with the active slide (2) and the passive slide (3). A seedling-pressing tray assembly (6) is mounted on both the seedling-picking actuator assembly (4) and the seedling-picking clamp assembly (5).
2. The one-step seedling plucking mechanism for a transplanter according to claim 1, characterized in that: The upper and lower transmission assembly (1) includes an upper and lower transmission slide rail (101). A transmission motor (102) is installed at the upper end of the upper and lower transmission slide rail (101). The motor shaft of the transmission motor (102) is connected to a transmission screw (103). The active slide (2) and the passive slide (3) are installed on the transmission screw (103). A slide rail cover plate (104) is installed at the lower end of the upper and lower transmission slide rail (101). A baffle (105) is connected to the lower side of the slide rail cover plate (104).
3. The one-step seedling plucking mechanism for a transplanter according to claim 2, characterized in that: The active slide (2) is hinged to the transmission screw (103) and slidably connected to the upper and lower transmission slide rails (101); a slider slide rail module (106) is installed on the top of the slide rail cover plate (104), and the passive slide (3) is fitted into the transmission screw (103) and slidably connected to the slider slide rail module (106).
4. The one-step seedling plucking mechanism for a transplanter according to claim 1, wherein: The seedling-taking actuator assembly (4) includes a first seedling-taking needle mounting plate (401) mounted on the active slide (2).

A pair of seedling-taking needles (403) are symmetrically mounted on each seedling-taking needle flap (402). An upper buckle (404) is mounted on one side of the inner side of the first seedling-taking needle mounting plate (401).
5. The one-step seedling plucking mechanism for a transplanter according to claim 4, characterized in that: The four seedling-taking needle flaps (402) are divided into two groups, left and right. Each group consists of two seedling-taking needle flaps (402). The two seedling-taking needle flaps (402) in each group are inclined relative to each other, and the corresponding seedling-taking needles (403) connected and installed on them are also inclined relative to each other. A protruding pusher head (4021) is machined on the mounting plate (401) between the two seedling-taking needle flaps (402) in each group.
