Technical Field

[0001] The invention belongs to agricultural machinery, specifically to parts of crop transplanting machinery, and in particular to an automatic seedling-dropping intelligent seedling tray. Background Art

[0002] The transplanting of crops such as vegetables has evolved from primitive manual transplanting to mechanical transplanting step by step. Both manual and mechanical transplanting require the cultivation of seedlings, and most of the current seedling cultivation is carried out in seedling trays. After the seedlings are grown in the seedling trays currently used, the seedlings need to be taken out of the seedling trays manually, which is not only time-consuming and laborious, but also not conducive to the mechanical transplanting of seedlings. Summary of the invention

[0003] In order to reduce the steps of manually taking the seedlings out of the seedling tray, save the time and manpower of manually taking the seedlings out of the seedling tray, and make the seedlings more conducive to mechanical transplanting, the present invention provides an automatic seedling-dropping intelligent seedling tray, which consists of a left half tray, a right half tray, a left stopper, a right stopper, a tension spring, a mounting hole, a connecting strip, a connecting plate, a supporting groove, a supporting strip, a left push block, a right push block, a longitudinal gear rod, longitudinal teeth, a longitudinal drive motor, an active buckle, a transverse gear rod, transverse teeth, and a transverse drive motor; the seedling tray is generally round Cone-shaped, the whole seedling tray is split into a left half tray and a right half tray along the center line of the cone, the two half trays are designed with a sealed connection interface at the splitting line, a left stopper is designed at the upper end of the left half tray, and a right stopper is provided in the middle of the right half tray, a tension spring is connected at the middle position of the left half tray and the right half tray, and a mounting hole is designed at the upper part of the splitting line of the left half tray and the right half tray, and the mounting holes must overlap when the left half tray and the right half tray are combined, and bolts are inserted in the mounting holes, and the left half tray and the right half tray can rotate around the bolts inserted in the mounting holes.

[0004] The seedling tray connecting frame is composed of two groups of connecting strips, connecting plates and supporting grooves. The connecting strip is a rectangular strip, and mounting holes corresponding to the left half tray and the right half tray are designed on the rectangular strip. The connecting plate is connected between the supporting groove and the rectangular strip, and a clamping strip protrudes inward from one of the sides of the connecting plate; the protruding parts of the connecting strip, supporting groove and clamping strip all face the inner side of the seedling tray connecting frame, and the outer side of the seedling tray connecting frame must be flat; the seedling tray is installed on the seedling tray connecting frame as a whole, and is movably fixed in the mounting holes designed on the rectangular strip by two bolts.

[0005] The push frame is composed of two groups of support bars, a left push block and a right push block. The upper part of the push frame is designed with support bars, the middle part is designed with a left push block, and the lower part is designed with a right push block. The left push block and the right push block both protrude toward the inside of the push frame; the contact parts of the left push block and the right push block with the left stop block and the right stop block need to be rounded.

[0006] The left block and the right block are both designed to be movable. When the left block and the right block are pushed forward toward the left push block and the right push block, the left block and the right block are both in an upright state; when the left block and the right block are pulled back in the opposite direction along with the left half disk and the right half disk, the left block and the right block become fallen down and bent due to the blocking effect of the left push block and the right push block, and the left push block and the right push block must be able to return and pass.

[0007] A plurality of seedling trays are integrally installed on a seedling tray connecting frame, and the plurality of seedling trays and the seedling tray connecting frame form a row of seedling tray integral units, and the propulsion frame can be inserted into the inner side of the seedling tray connecting frame, and the plurality of rows of seedling tray integral units are close to each other in the width direction to form a seedling tray combination, and each row of seedling tray integral units in the seedling tray combination can be displaced in the length and width directions.

[0008] A transverse gear rod is designed at the end position of a clamping strip in the connection plate of the seedling tray connecting frame, a transverse gear rod fixing sleeve is designed on the periphery of the transverse gear rod, a movable buckle is designed at one end of the transverse gear rod close to the clamping strip of the connection plate, the movable buckle movably connects the transverse gear rod with the connection plate, transverse teeth are designed at the lower part of the transverse gear rod, the transverse teeth are installed on the output shaft of the transverse drive motor, and the transverse drive motor is a stepping motor which can change the winding power-on sequence and can realize forward and reverse rotation.

[0009] A longitudinal gear rod, longitudinal teeth and a longitudinal drive motor are designed on the side of the seedling tray combination and the side position of the connecting strip of the seedling tray connecting frame. A longitudinal gear rod fixing sleeve is designed on the periphery of the longitudinal gear rod. The longitudinal gear rod acts on the side of the connecting strip. Longitudinal teeth are designed under the longitudinal gear rod. The longitudinal teeth are installed on the output shaft of the longitudinal drive motor.

[0011] The whole of the seedling tray assembly is placed on the frame, and then the longitudinal driving motor is started, the longitudinal driving motor drives the longitudinal teeth, the longitudinal teeth drive the longitudinal gear rod, and the longitudinal gear rod is pushed to the side of the connecting strip, so that the seedling tray assembly is advanced longitudinally, and the supporting groove of the seedling tray connecting frame is aligned with the supporting strip of the propulsion frame, so that the supporting strip is supported in the supporting groove, and the left stopper and the right stopper are respectively aligned with the left push block and the right push block, and then the transverse driving motor is started, the transverse driving motor drives the transverse teeth, and the transverse teeth drive the transverse gear rod, and the transverse gear rod acts on the connecting plate of the seedling tray connecting frame to advance the seedling tray assembly toward the left push block and the right push block; at this time, the left push block acts on the left stopper on the left half tray to lift the left half tray, and at the same time, the right push block acts on the right stopper on the right half tray to lift the right half tray, and the left half tray and the right half tray of the seedling tray as a whole are all opened downward, and the seedlings placed in the seedling tray as a whole naturally fall down due to the force of the left half tray and the right half tray being lifted and the gravity of the seedlings themselves, and are planted in the field or automatically by the transplanter. When the seedlings of the whole row of seedling tray units have all fallen, the transverse driving motor performs a reverse action, the movable buckle clamps the clamping strip on the connecting plate, and the seedling tray unit is pulled back, and the left stopper and the right stopper are respectively acted in the opposite direction by the left push block and the right push block, and the movable left stopper and the right stopper fall down, so that the left push block and the right push block return through; when the transverse gear rod is pulled back to one end of the clamping plate on the movable buckle and enters the transverse gear rod fixing sleeve, the clamping plate on the movable buckle is separated from the clamping strip on the connecting plate, and the transverse driving motor continues to reverse, and the transverse gear rod continues to pull back, so that the whole of the movable buckle completely leaves the connecting plate. At this time, the transverse driving motor stops running, and the longitudinal driving motor starts to push the adjacent row of seedling tray units to a position where the support groove of the seedling tray connecting frame is aligned with the support strip of the pushing frame; the above action process is repeated and implemented in a cycle to complete the task of dropping all seedlings in the entire seedling tray combination.

[0012] The empty seedling tray after the seedlings fall can be pulled together by the tension spring installed in the middle of the left half tray and the right half tray, so that the left half tray and the right half tray of the seedling tray as a whole return to their original positions.

[0013] The seedling tray combination can be placed in layers and stacked in multiple layers through the support of the connecting plate of the seedling tray connecting frame, so as to save the placement space of the seedling tray combination and facilitate the moving and transportation of the seedling tray combination.

[0014] The beneficial effects of the present invention are: the seedlings can be automatically dropped from the seedling tray, which saves time and manpower and is more conducive to the mechanical transplanting of the seedlings. BRIEF DESCRIPTION OF THE DRAWINGS
