Abstract
Abstract Transplanting equipment comprises a line of individual plant pick-up devices, first support means for transversely moving a first row of containers into vertical alignment with the pick-up devices, control means for bringing the pick-up devices into a plant-supporting or plant-releasing mode as appropriate, horizontal drive means operative to bring the pick-up devices into vertical alignment with the containers of a second row having a different center-to-center spacing to the containers of the first row, second support means for transversely moving the second row of containers out of vertical alignment with the pick-up devices, and vertical drive means for moving the pick-up devices towards or away from the first and second support means to allow the support or release of plants by the pick-up devices as determined by the control means.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
Transplanting equipment comprising; a line of individual plant pick-up devices, first support means for transversely moving a first row of containers into vertical alignment with said plant pick-up devices, control means for bringing said plant pick-up devices into one of a plant supporting and plant-releasing mode, horizontal drive means operative to bring said plant pick-up devices into vertical alignment with containers of a second row having a different centre-to-centre spacing than said containers of said first row, second support means for transversely moving said second row of containers out of vertical alignment with said plant pick-up devices, and vertical drive means for moving said plant pick-up devices towards and away from said first and second support means to allow support and release of plants by said plant pick-up devices as determined by said control means.
Claim 2
Dependent Claim
135 words
Transplanting equipment comprising; a line of individual plant pick-up devices, first support means for transversely moving a first row of containers into vertical alignment with said plant pick-up devices, control means for bringing said plant pick-up devices into one of a plant supporting and plant-releasing mode, horizontal drive means operative to bring said plant pick-up devices into vertical alignment with containers of a second row having a different centre-to-centre spacing than said containers of said first row, second support means for transversely moving said second row of containers out of vertical alignment with said plant pick-up devices, and vertical drive means for moving said plant pick-up devices towards and away from said first and second support means to allow support and release of plants by said plant pick-up devices as determined by said control means.
Claim 3
Dependent Claim
23 words
Transplanting equipment as claimed in claim 1 in which each said plant pick-up device comprises a helically-wound probe having a central longitudinal axis.
Claim 4
Dependent Claim
62 words
Transplanting equipment as claimed in claim 2 in which said control means comprises a rotary drive operative to rotate said plant pick-up devices about said longitudinal axes a rotational sense to the helix so that said plant pick-up devices support a respective plant and in a contrary rotational sense to the helix so that said plant pick-up devices release a respective plant.
Claim 5
Dependent Claim
96 words
Transplanting equipment as claimed in claim 1 in which said plant pick-up devices are interconnected by flexible ties, said drive means, being operative to move said plant pick-up devices between a bunched first configuration wherein said flexible ties are slack and said plant pick-up devices are spaced to correspond to a centre-to-centre container spacing in one of said first and second rows and a second spaced configuration wherein said flexible ties are taut and said plant pick-up devices are spaced to correspond to the centre-to-centre container spacing in the other of said first and second rows.
Claim 6
Dependent Claim
54 words
Transplanting equipment as claimed in claim 1 in which adjacent pick-up devices have a predetermined, fixed spacing and said horizontal drive means is operative to move the plant pick-up devices between selected containers in one of said first and second rows and correspondingly spaced containers in the other of said first and second rows.
Claim 7
Dependent Claim
60 words
Transplanting equipment as claimed in claim 1 in which said first support means comprises a first endless conveyor disposed transversely to said line of plant pick-up devices at one extreme of horizontal travel and the second support means comprises a second endless conveyor disposed transversely to said line of plant pick-up devices when at the other extreme of horizontal travel.
Claim 8
Dependent Claim
49 words
Transplanting equipment as claimed in claim 1 for transplanting plants from containers in said first row into larger sized containers in said second row and includes supply means for introducing particulate material into gaps between root portions of plants and walls of said larger-size containers in said second row.
Claim 9
Dependent Claim
41 words
Transplanting equipment as claimed in claim 7 in which said supply means comprises a conveyor operative to convey particulate material over containers in said second row, and displacement means operative to displace particulate material into said containers in said second row.
Claim 10
Dependent Claim
36 words
Transplanting equipment as claimed in claim 7 in which said supply means comprises means for introducing a mixture of particulate materials into gaps between root portions of plants and walls of containers of said second row.
Claim 11
Dependent Claim
33 words
Transplanting equipment as claimed in claim 7 in which said supply means includes hinged loading chutes which pivot to allow horizontal withdrawal of said second row of containers after receipt of plants therein.
Claim 12
Dependent Claim
24 words
Transplanting equipment as claimed in claim 1 in which said containers in each of said first and second rows have a uniform centre-to-centre spacing.
Claim 13
Dependent Claim
143 words
Transplanting equipment as claimed in claim 1 including a pot dispenser system comprising a first support means defining a space for a first, bottom pot of a stack of pots, a second support means defining a space for a second, penultimate pot of said stack of pots, and control means operative sequentially to effect engagement of a first bottom pot by said first support means, engagement of the second, penultimate pot by said second support means, disengagement of said first support means from said first, bottom pot to allow said first, bottom pot to fall away from said stack, return of said first support means to a pot-engaging position and release by said second support means of said second, penultimate pot of the stack allowing the stack of pots to drop until said second, penultimate pot is engaged by said first support means.
