Abstract
Abstract This invention relates to a planting machine for depositing plants in planting furrows (28). The machine includes a frame (10), rotatable wheels (11, 12) and plant holding or storage stations (15, 16), one or more plant conveyor paths (21, 21′), and means for ensuring that the plants are deposited singly. With the intension of improving the planting rate of such a machine it is proposed in accordance with the invention that the conveyor paths (21, 21′) discharge into a plant-feed chute (23); and in that a device (29) arranged for linear movement in the chute (23) contributes towards feeding the plants singly into the feed chute (23) and also to depositing the plants singly in the planting furrow.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
221 words
A planting machine for depositing plants in planting furrows (28) formed in the soil, ground or earth, said machine comprising a frame carried by a number of rotatable wheels (11, 12, 13); one or more plant holding stations (15, 16) which are localized at a distance from the ground surface; one or more conveyor paths (21, 22) for moving plants transferred to said conveyor path or paths (21, 22) sequentially towards the ground in a manner to plant said plants singly in said planting furrows (28); and further comprising means which ensure that only one plant at a time is deposited in a furrow, characterized in that said conveyor path or paths (21, 21′) discharge into a chute (23) which extends substantially in the axial direction of the machine in the proximity of the ground surface and in which there is arranged a linearly displaceable device (29) which in one position of movement uncovers the opening of a conveyor path to permit a plant to be moved into said chute (23) and in another position of movement is intended to move in a manner to transfer said plant in a direction towards the free end of the chute (23) and deposit the plant in the planting furrow (28) while simultaneously covering the outlet or discharge end of the conveyor path (21′).
Claim 2
Dependent Claim
221 words
A planting machine for depositing plants in planting furrows (28) formed in the soil, ground or earth, said machine comprising a frame carried by a number of rotatable wheels (11, 12, 13); one or more plant holding stations (15, 16) which are localized at a distance from the ground surface; one or more conveyor paths (21, 22) for moving plants transferred to said conveyor path or paths (21, 22) sequentially towards the ground in a manner to plant said plants singly in said planting furrows (28); and further comprising means which ensure that only one plant at a time is deposited in a furrow, characterized in that said conveyor path or paths (21, 21′) discharge into a chute (23) which extends substantially in the axial direction of the machine in the proximity of the ground surface and in which there is arranged a linearly displaceable device (29) which in one position of movement uncovers the opening of a conveyor path to permit a plant to be moved into said chute (23) and in another position of movement is intended to move in a manner to transfer said plant in a direction towards the free end of the chute (23) and deposit the plant in the planting furrow (28) while simultaneously covering the outlet or discharge end of the conveyor path (21′).
Claim 3
Dependent Claim
31 words
A machine according to Claim 1, characterized in that the free end of the chute (23) discharges beneath ground level (25) but above the bottom (27) of the planting furrow (28).
Claim 4
Dependent Claim
30 words
A machine according to Claim 1, characterized by means (33, 36) which subsequent to depositing a plant in said furrow causes foil to embrace the lower part of the plant.
Claim 5
Dependent Claim
17 words
A machine according to Claim 1, characterized in that the displaceable member is an elongated plunger (29).
Claim 6
Dependent Claim
43 words
A machine according to Claim 3, characterized by blades (35, 36) which are located on both sides of the deposited plant and connected with a moveable arm (31), said blades being intended to cause soil to embrace the root end of the plant.
Claim 7
Dependent Claim
40 words
A machine according to Claim 5, characterized in that the arm (31) extends parallel with the feed tube (23); and in that the blades (35, 36) are carried and localized by a system of pivotal arms (32, 33, 34, 35).
Claim 8
Dependent Claim
55 words
A machine according to one or more of the preceding claims and intended to be towed by a towing vehicle, characterized in that the movement of the displaceable member (29) and movement of the blades (35, 36) is transmitted via a system of arms initially from the rotatable shaft (37) carrying the wheels (11, 12).
Claim 9
Dependent Claim
40 words
A machine according to one or more of the preceding claims, characterized in that the blades (35, 36) can be adjusted in a manner to set the angle of the blades in relation to the forward movement of the machine.
