The tree planting machine includes a vehicle main unit, a beam, and a plurality of planting devices. The beam is attached to the vehicle main unit along the vehicle width direction, and is longer than the vehicle width of the vehicle main unit. The plurality of planting devices are attached to the beam.

The present invention discloses a mobile operating platform for a paddy field, including a body, a power generating device, a movement control system, a draft control system and an automatic leveling system, where the power generating device, the movement control system, the draft control system and the automatic leveling system are all mounted on the body. The present invention has a compact overall structure, and utilizes the pressure of a water flow to realize the movement of the platform, and can fully utilize the characteristics of the water flow to reduce power consumption, and avoid the use of a heavy and complicated traditional walking device, the entire mobile operating platform for a paddy field does not contact the ground, saving mechanical power and avoiding damage to an aquatic crop; the draft control system adjusts a draft by the amount of water filled in a closed cavity in the body.

A furrow opener on an agricultural ground working implement has an opener body supported on a tool supporting shank of the implement and a replaceable furrowing tip body on the opener body. A delivery passage extends through the opener body and the tip body to deposit granular material in a furrow formed in the ground by the furrow opener. The tip body has a vertical knife portion and laterally protruding wings. Each wing further includes a soil shield portion projecting upwardly from the inner edge of the respective wing alongside the corresponding side surface of the opener body so as to resist penetration of soil into the chamber through a seam between the inner edge of the wing and the corresponding side surface of the opener body.

A sapling retrieval apparatus coupled to a chassis, which extends in a fore-aft direction, includes ground-engaging supports to facilitate propelling the chassis. The sapling retrieval apparatus comprises a gripping unit for retrieving a linear row of saplings from a tray and releasing the row of saplings, a transfer unit, and an indexing unit. The transfer unit moves the released linear row of saplings to the indexing unit for individual delivery of a sapling for planting as the chassis is propelled.

A sapling planting apparatus coupled to a chassis wherein the chassis includes a ground-engaging supports to facilitate propelling the chassis. The sapling planting apparatus comprises a screw; a nut in threaded engagement with the outer surface of the screw; a motor operatively coupled to the screw to rotatably drive the screw wherein rotation of the screw translates the nut; a tube for delivering the sapling towards the ground; and a spade for penetrating the ground for planting the sapling. The tube may be coupled to the nut and is telescopically extendable in a downward direction from a rest position wherein translating the nut in a first direction coincides with extending the tube in a downward direction.

A method of operating a sapling hydrating system for a planting apparatus. The method comprising determining a release pressure of hydrating fluid for a release valve to hydrate a sapling based on a target distribution rate of the hydrating fluid, wherein the target distribution rate is received via an input signal. The method further comprising controlling a supply pressure of the hydrating fluid from a pump to be greater than or equal to the release pressure, and controlling an unloading valve fluidly disposed between the pump and a hydrating fluid storage tank. The unloading valve regulating a maximum supply pressure. The method further includes controlling the release valve to provide a first portion of the hydraulic fluid to the release valve at an unloading pressure greater than or equal to the release pressure, and directing the remainder of the hydrating fluid back to the storage tank.

An automated planter apparatus for inserting a rootstock, rooting stock or plantings into the ground, especially useful in hop yards, vineyards and orchards, the planter apparatus mountable to a tractor or trailer, and with grapes as a preferred rooting stock. Apples, or any other type of grafted tree or vine may be planted in the alternative. The planter apparatus includes a chain driven grabber mechanism, attached to a chain loop and driven by sprockets at each end, the grabber mechanism able to grasp and insert the rooting stock into the soil at precisely predetermined points, preferably aided by GPS (Global Positioning System). The grabber mechanism includes a pair of grabbers that receive the rooting stock at a pick-up, and then rotate from an open position to a closed position as the chain loop proceeds around a forward sprocket, rotating the grabber mechanism to a planting release.

A first machine of a tree planting system includes: a cultivator cultivating soil where a plant for tree planting is to be planted; a first traveling device traveling with the cultivator; and a cultivated position detector obtaining and outputting actual cultivated positions corresponding to positions of the cultivator while the cultivator travels with the first traveling device and cultivates the soil. A management device of the tree planting system stores actual cultivated positions. A second machine of the tree planting system includes: a planting device planting a plant in the soil; a second traveling device traveling with the planting device; a planting device position detector obtaining a position of the planting device; and a controller controlling a position of the planting device based on: actual cultivated positions acquired from the management device; and the position of the planting device at the timing when a plant is planted.
