Definitions

• the invention relates to a circular transport system mainly for cultivating plants.
• the transport system which is capable of advancing the plants while imparting to them an even, continuous distance during the process of growth, consists of two horizontal rotor bodies located about a common vertical axis as well as a number of transport baskets for the plants.
• One of the rotor bodies is helical whereas the other one has a number of radial guide rails, which forcibly conduct the plants every one of which is located within its basket along the helical track from the centre to the periphery, with either one or both of the rotor bodies rotating.
• the transport systems for plant cultivation known today where while imparting a distance during the process of growth an attempt is made to make optimal use of the area, consist as a rule of channels in which the plants are placed at the mutual final distances of the plants. By moving these channels from one another during the process of growth the area is utilised but only in one direction.
• the transport system according to the invention has the special feature that it can advance the plants during their process of growth while increasing the distance evenly and continuously in several horizontal directions, inasmuch as the system consists of two horizontal rotor bodies capable of rotating separately or jointly about a common vertial axis so that the plants located each in its transport basket are carried away from one another in the course of such rotation.
• the transport system acts in such a way as to cause the transport baskets with plants to be carried from the centre towards the periphery, inasmuch as the helical rotor body conveys them in an outward direction at the same time as the rotor body with the radial guide rails ensures the required mutual distance between the transport baskets.
• a simple embodiment of the assembled transport system according to the invention consists in that the helical body is located within a vessel in which water with nutrient added can circulate or the level of water may be raised and lowered entirely in accordance with the requirements of the plants.
• Another embodiment may consist in designing the helical body in such a way as to ensure that it both forms a channel or is equipped with such water supply devices as to enable water to be supplied to the plants either in a continuous flow or subdivided into sections.
• a third embodiment consists in that such water supply devices are provided along the radial guide rails or when designing the guide rails themselves as are able to ensure that the plants are supplied with the requisite amount of water.
• a fourth embodiment consists in that the helical body and the transport baskets are provided with tooth-type devices so that the baskets are rotated about their own axes, inasmuch as the said devices actuate the transport baskets to cause such a rotation when the system is working.
• Fig. 1 shows a system seen from above with the various main components of which the system can consist shown partly.
• Fig. 2 shows the system as seen from the side.
• Fig. 3 shows a round transport basket with tooth-type devices.
• Fig. 4 shows a square transport basket.
• Fig. 5 shows a detail of the system seen in perspective, indicating various embodiments.
• the system as installed in a vessel is illustrated at item 14.
• the helical body and the radial guide rails are located about a common vertical axis item 15.
• Holders for the helical body are shown as item 18, and the tooth-type devices which can act on the transport baskets are shown on the helical body as item 19.
• fig. 2 which is the system seen from the side are shown, in addition to the item nos. illustrated in fig. 1 a water inlet for the vessel item 22 and a drain item 24 as well as a system raised above ground level with supports item 23.
• Fig. 3 shows a transport basket item 13 provided with tooth-type devices item 19.
• the figure is a view from the side and from above.
• Fig. 4 shows a square transport basket item 13a.
• the figure is a view from the side and from above.
• the transport baskets have that common characteristic that they are available in innumerable forms, and an attempt must be made to use transport baskets already available.
• Fig. 5 shows a detail of the system seen in perspective, and apart from the item nos. shown in the preceding figures this figure shows water supply devices along the helical body item 20 and the supply of water to the helical body designed as a channel item 20a. Also water supply devices are shown along the radial guide rails item 21.
