[0012] In use, the seedling tray is placed on the seedling release board. Under the action of gravity, the seedling tray slides down the seedling release board. After the seedlings are sorted and arranged by the seedling separation board, they slide between the first ends of two adjacent guide rails. At the same time, the clamping component, which rotates to the bottom of the conveyor sprocket, separates its left and right clamps to the sides under the action of the guide rails, thereby clamping the seedlings between the guide rails and driving the seedling tray to move along the length of the guide rails. When the first end of the seedling tray moves to the bottom of the arc groove of the guide rail, the rotating ratchet pushes the seedling tray downwards, so that the seedling tray and the seedlings are separated in an orderly manner. The seedlings move to the end of the guide rails, and the left and right clamps of the clamping component come together under the action of the tension spring to restore their original shape. Thus, the seedlings are released from the clamps and fall freely, thus completing the seedling removal.

[0013] The features of this utility model are that the seedlings are picked up accurately and orderly without missing any seedlings, and the clamping components are made of rubber material so as not to damage the seedlings when picking them up. The seedling detachment mechanism can stably and reliably separate the seedlings and seedling trays. The device is simple to operate and has high work efficiency. Attached Figure Description

In the unclamped state, the distance between two adjacent clamping chains is 10 mm. This distance is suitable for the stem of the seedling above the soil to enter between two adjacent clamping pieces (510). The clamping pieces (510) are made of rubber material, the purpose of which is to prevent damage to the seedling when clamping and contacting it.

[0031] Further optimization of the scheme: the seedling guiding mechanism includes a seedling guiding plate (17). The arc-shaped structure of the seedling guiding plate (17) on the side near the active shaft (1) is coaxial with the axis of the active shaft (1). The top of the arc-shaped structure of the seedling guiding plate (17) is fixed to the fixed crossbeam (19). The front end of the arc-shaped structure of the seedling guiding plate (17) is fixed to a seedling separating plate (16). Two supports (20) are fixed to the bottom of both ends of the fixed crossbeam (19). The two supports (20) are parallel and symmetrically arranged on the upper surface of the two side support plates. The planar structure of the seedling guiding plate (17) on the side away from the active shaft (1) is parallel to the upper surface of the two side support plates, and the lower end is fixed to the inner side of the two side support plates. Several guide rails (18) are fixed to the upper surface of the planar structure of the seedling guiding plate (17). The several guide rails (18) are arranged sequentially at intervals along the length direction of the active shaft (1). The arc groove of the guide rail (18) is located directly above the square opening of the seedling guiding plate (17).

When the clamping assembly (5) moves to the first end of the guide rail (18), the two rollers (507) roll tangentially with the guide rail (18) and separate to both sides, thereby driving the left and right clamping plates to clamp the seedlings between the two guide rails (18). At the same time, the clamping assembly (5) continues to move along the length direction of the guide rail (18). When the clamping assembly (5) moves to the end of the guide rail (18), the two rollers (507) retract under the action of the tension spring (509), causing the two clamping plates (510) to separate.

The contact surface of the seedling release plate (15) supporting the seedling tray is provided with several grooves along the downward direction of the seedling tray. The grooves match the lower end of the seedling tray body. This setting is to ensure that the seedling tray will not shift to the sides during the downward movement, so as to smoothly enter between the seedling separating plates (16). When the seedling tray slides down to the lowest end of the seedling release plate (15), the seedling tray is located between the seedling guide plate (17) and the seedling release plate (15), and the stem part of the seedling is located on the upper end surface of the seedling guide plate (17).

[0034] In a further optimized scheme, the seedling removal mechanism is located below the seedling guiding mechanism, including two third-row rhomboid bearings (10) fixed to the outer side of the two side support plates.

The several dial ratchet wheels (12) are arranged sequentially along the length direction of the second driven shaft (9), and the several dial ratchet wheels (12) are located directly below the arc grooves opened on the several guide rails (18).

[0035] The double sprocket (3) drives the dial sprocket (11) to rotate, the dial sprocket (11) drives the second driven shaft (9) to rotate, the second driven shaft (9) drives the dial ratchet (12) to rotate, the dial ratchet (12) is set one-to-one with the guide rail (18), and the dial ratchet (12) and the arc groove opened on the guide rail (18) are set coaxially. The end of the teeth of the dial ratchet (12) penetrates the square hole opened on the seedling guide plate (17). The seedling tray moves towards the tail end along the length direction of the guide rail (18). When the head end of the seedling tray enters the arc groove opened on the guide rail (18), the teeth of the rotating dial ratchet (12) press down on the upper end of the seedling tray, so that the seedling tray and the seedling are separated in an orderly manner.
