Abstract
Abstract An automatic planting machine for planting plants particularly small and/or young trees, specially designed for forestation and/or reforestation and the like. The machine has, in each of its main wheels, at least one planting tube radially movable and capable of projecting through an aperture in the rim of the wheel coincident with the moment at which a plant is set in the furrow opened by the machine. To open the furrow in the soil, a furrow opening blade is provided in front of each main wheel. Behind each main wheel a pair of auxiliary rear wheels are provided which are capable of tamping the soil at the sides of the plant set in the furrow, and each of said auxiliary rear wheels may be sloped. Means are provided which are capable of feeding plants, one at a time, to each planting tube, the operation of said feeding means and the movement of each planting tube being timed with the rotation of the pertinent main wheel. The machine may be provided with means (e.g. hydraulic) for removing the main wheels from contacting the ground for transportation. A water reservoir and water feeding means may be provided for feeding water to the planted plants. Optionally, conveyor means for forwarding plant containing cases, may also be provided.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
170 words
Automatic planting machine for planting in rows, small trees and the like into the bottom of a furrow opened in the soil, said furrow may be opened by the same machine, said machine comprising a chassis having at least a pair of sides, a main wheel at each side of the chassis, independent axles for each main wheel and rotatably supported by said chassis, each main wheel having a rim, at least one through aperture in each rim, a planter having a planting tube slidably mounted in each of said through apertures and timed with the rotation of the corresponding main wheel to project to the outside of said through opening and rim upon said through opening facing the bottom of said furrow, each planting tube having an input end, and means capable of feeding plants, one at a time, into the input end of each planting tube to enable planting of said plant into the bottom of said furrow upon said through opening facing the bottom of said furrow.
Claim 2
Dependent Claim
170 words
Automatic planting machine for planting in rows, small trees and the like into the bottom of a furrow opened in the soil, said furrow may be opened by the same machine, said machine comprising a chassis having at least a pair of sides, a main wheel at each side of the chassis, independent axles for each main wheel and rotatably supported by said chassis, each main wheel having a rim, at least one through aperture in each rim, a planter having a planting tube slidably mounted in each of said through apertures and timed with the rotation of the corresponding main wheel to project to the outside of said through opening and rim upon said through opening facing the bottom of said furrow, each planting tube having an input end, and means capable of feeding plants, one at a time, into the input end of each planting tube to enable planting of said plant into the bottom of said furrow upon said through opening facing the bottom of said furrow.
Claim 3
Dependent Claim
239 words
The automatic planting machine of claim 1, wherein said planter comprises a guiding sleeve rigidly mounted on the inside of said rim and facing said through opening, said planting tube being slidably mounted in said guiding sleeve, said guiding sleeve having at least one slot, a pin connected to said planting tube and emerging through said slot, a lever pivoted to said pin at one end portion and having an opposite end portion pivoted to said rim, a cam roller rotatably mounted on an intermediate portion of said lever, a stationary cam track having a first straight portion and a second curved portion, said cam roller being capable of entering in contact with said first straight portion of the cam track during a first portion of a complete turn of the main wheel, thereby being capable of retracting said planting tube into said through opening, thereafter entering in contact with said second curved portion of the cam track during a second portion of the turn of the wheel thereby being capable of maintaining retracted said planting tube, and thereafter removing from contacting said cam track at the end thereof during the last portion of said complete turn of the main wheel, thereby being capable of projecting again said planting tube through said through aperture due to the existance of resilient means connected to said lever urging said planting tube through said through opening towards the outside of said rim.
Claim 4
Dependent Claim
179 words
The automatic planting machine of claim 1, wherein said means capable of feeding plants comprises a cam follower shaft rotatably supported by said chassis and parallel to one of said independent axles, a cam mounted on said axle, said cam follower shaft rigidly supporting a cam follower in driven relationship with said cam, a lever controlled by said cam follower shaft, a stationary platform defining a deposit for plants to be planted and an exit, and a pivotable platform located below said stationary platform, a gate member pivotally supported by said chassis and connected to said lever, said gate member being capable of opening and closing said exit of said stationary platform, said movable platform being likewise connected to said lever and projecting beyond said stationary platform, and a stop arranged above said pivotable platform ahead of said stationary platform and thereby of its exit, whereby, upon said lever moving from one end position towards the other, said gate becomes opened and the front end portion of said pivotable platform approaches said stationary platform and consequently likewise said stop.
Claim 5
Dependent Claim
81 words
The automatic planting machine of claim 1, wherein said chassis has a front portion and a rear portion, said rear portion having at each corner with said sides a pair of rear auxiliary wheels defining in between them, at the portion of contact with the soil, a space which is at least equal to the maximum cross-sectional area of the plant to be planted, each pair of wheels being capable of tamping the earth of the furrow adjacent the planted tree.
Claim 6
Dependent Claim
26 words
The automatic planting machine of claim 4, wherein the rear wheels of each pair of rear wheels converge towards the point of contact with the soil.
Claim 7
Dependent Claim
55 words
The automatic planting machine of claim 4, wherein the rear portion of said chassis pivotally supports a drawbar having connected thereto, at an intermediate portion thereof, a jack capable of varying the distance between said chassis and said drawbar for raising said main wheels from the soil, to achieve the transport position for said machine.
Claim 8
Dependent Claim
37 words
The automatic planting machine of claim 2, wherein a water feeding arrangement debouches into said guiding sleeve, said water feeding arrangement including timing means adapted to supply water to the soil upon a plant having been planted.
Claim 9
Dependent Claim
38 words
The automatic planting machine of claim 3, wherein said chassis supports additional conveying means for conveying cases containing plants towards an attendant's post for an attendant who will replenish the deposit of plants formed by said stationary platform.
Claim 10
Dependent Claim
16 words
The automatic planting machine of claim 8, wherein said additional conveying means comprises a rotatable platform.
Claim 11
Dependent Claim
37 words
The automatic planting machine of claim 8, wherein said additional conveying means comprises at least a pair of endless conveyors moving in one direction, in between which there is a third endless conveyor moving in opposite direction.
Claim 12
Dependent Claim
66 words
The automatic planting machine of claim 4, wherein between said pair of auxiliary rear wheels and said main wheel, a pair of scoopers is arranged having a distance in between them which is as the minimum equal to the maximum cross-sectional area of the plant to be planted, said scoopers are arranged at a height with regard to the chassis which is located above said soil.
