The invention relates to a method in a seedling planting machine and to a seedling planting machine, in which, seedlings are extracted from a seedling storage. In the method, the seedling storage is held in its place on a storage track of the planting machine with first holding elements by a first toothed bar. The seedling storage is transferred on the storage track of the planting machine by moving second holding elements by a second toothed bar, in relation to the first holding elements and to the storage track, so that the seedling storage comes into contact with the second holding elements. The seedling storage is transferred by the second holding elements a transfer distance forward on the storage track. The seedling storage is transferred by the first holding elements, and the seedling storage is detached from the second holding elements.

The present invention relates to an apparatus for planting and treating seedlings of an agricultural plant. In particular, the apparatus is adapted for planting and treating sugar cane seedlings. The apparatus comprises means for moving the apparatus over a field with soil in which the seedlings are to be planted. Further, it comprises a tray for holding a plurality of seedlings and a furrow opener for automatically creating a furrow in the field when the apparatus is moved over the field. Moreover, the apparatus comprises a spraying device for applying a fertilizer, an insecticide, a fungicide, and/or a nutrient to the furrow. Furthermore, the apparatus comprises a furrow compactor that is adapted to close the furrow with soil and to compact the soil surrounding the seedling in the closed furrow. Moreover, the invention relates to the use of this apparatus for planting a seedling of a graminaceous plant, in particular the seedling of a sugar cane plant.

According to some embodiments of the present invention, an automated planter may be comprised of a series/sequence of automated sub-systems. The sequence of sub-systems may be designed to receive trays/cartridges of seedlings, withdraw the seedlings from the trays and plant the seedlings one by one as the automated planter advances, all in an automated fashion

A planting apparatus of nursery tree includes an auger, a guide member having a hollow tube shape, a blade member, sliders, and motors The auger, the guide member and the blade member form the nested structure of the three-layer which are centered upon the auger, and the auger and the blade member are rotation members rotating on the same vertical axis line. By such a constitution, desired planting hole can easily be excavated, and the ground around the excavated hole and a root clump of the nursery tree can be leveled, covered and pressed by the blade member without forming a gap while holding the nursery tree by the guide member not to be inclined.

Disclosed is a high-speed transplanting mechanism having a laterally openable/closable duckbill, the mechanism comprising: a duckbill soil penetration angle adjusting arm (5) disposed on a duckbill transplanting portion (9), the duckbill soil penetration angle adjusting arm (5) has a rear arm (52) and a front arm (54) with one end each thereof connected by means of a reverse-threaded adjusting screw rod (8), and other ends thereof hingedly connected to an adjusting arm support shaft (102) and the duckbill transplanting portion (9) respectively. A length of the reverse-threaded adjusting screw rod (8) enables the duckbill to tilt in a direction opposite to a driving direction of a transplanting machine, and a vertical central straight line of the duckbill makes an angle with the ground capable of being adjusted between 65-85. By adjusting the reverse-threaded adjusting screw rod, the duckbill transplanter can be tilted in a direction opposite to a driving direction of the transplanting machine, and a seedling can be supported and pushed upright by a forward inertia thereof and the action of a rolling wheel, overturning the conventional notion that seedling delivery and transplanting must be stationary, and increasing the efficiency and quality of transplanting.

There is provided a seedbed holding unit capable of reliably and firmly holding a seedbed with a simple structure, causing no damage to a plant. A seedbed holding unit 160 that holds a seedbed B used in plant cultivation includes a first holding member 170 and a second holding member 180 that are rotatable relative to each other about a predetermined rotation axis A, the first holding member 170 is provided with a first claw part 173 in a fixed state, the second holding member 180 is provided with a second claw part 183 in a fixed state, and the seedbed B is held between the first claw part 173 and the second claw part 183 by rotating the first holding member 170 and the second holding member 180 relative to each other.

A plant dispensing unit for planting plants may include a set of ejectors for engaging and retaining plant balls of a row of plant balls in a tray having a plurality of rows. Each ejector may be configured to eject the engaged plant ball with force. A plant dispensing unit may include a funnel assembly configured to receive an ejected plant ball and direct it to a shoe configured to receive the ejected plant ball from the funnel and position the plant ball for planting. A plant dispensing unit may include a control system coupled to an ejector drive system a shoe drive system, for operatively coordinating actions of the plant dispensing unit. A plant dispensing unit may include a flat feeder for operating a tray feeding system of the plant dispensing unit to index rows of the tray for engagement by the ejectors.

A seedbed supporting member and a panel supporting member are configured such that, in a state where a seedbed held in a first seedbed holding member and a through hole portion of a first panel overlap with each other, a seedbed held in a second seedbed holding member and a through hole portion of a second panel, which correspond to this seedbed and this through hole portion, respectively, overlap with each other. An arrangement spacing in a first direction between the through hole portion of the first panel and the through hole portion of the second panel corresponding to each other is equal to an arrangement spacing in the first direction between a first transplantation arm and a second transplantation arm.

The present invention provides a plant transplanting device that achieves rapid and stable transplantation with a simple structure and at low cost, prevents damage to the plants, and can be automated easily. A plant transplanting device 100 that transplants a seedbed B from a plant holder 110 to a growing pallet 120 includes a holder holding mechanism 130 for holding the plant holder 110, a pallet holding mechanism 140 for holding the growing pallet 120 above a holder holding position in which the holder holding mechanism 130 holds the plant holder 110, and a push-up mechanism 150 for pushing the seedbed B held in the holder seedbed-holding hole 111 upward so as to insert the seedbed B into the pallet seedbed-holding hole 121.

A tractor suspension type automatic transplanting machine for plug tray seedlings includes land wheels, a machine frame, a three-point linkage, a seedling pickup mechanism, a plug tray conveying device, a plug tray recovery device, seedling separating and planting devices driven by land wheels, and a watering device. Through front and rear drive cylinders, the seedling pickup mechanism is driven to move front and back to pick up seedlings above plug trays and release seedlings above a seedling guide device. Juxtaposed left and right seedling pickup modules in the seedling pickup mechanism are driven by left and right drive cylinders, to move left and right and pick up seedlings after combing, and to release seedlings after separating towards left and right. Plug trays fall onto a plug tray conveyor belt of the plug tray recovery device and slides into a plug-tray-recovery stacking box.
