Definitions

  • Hothouses of every kind are substan- tially heated by firing of oil and especially in northern countries where solar heat is rather sparce large amounts of energy are consumed to maintain a constant and rather high heating temperature in hothouses.
  • the applicant has considered it possible to save energy by heating only say half the space of a hothouse and bring together and keep the plants there during the darkest and coldest period of the day and night. Then when the solar heat and the higher outer temperature help to increase the heat in the hothouses, the plants are uniformly distributed over the entire interal hothouse space.
  • the plants are usually placed in clay pots or containers of other material and are then set out closely spaced on benches or tables in the hothouses where they are rapidly forced into suitable sizes.
  • the plant tables or benches are fixedly arranged along the internal spaces of the hot ⁇ houses in long rows with suitable passages between the rows of plant tables to leave the appropriate room for work and transport.
  • the entire areas of the hothouses are exploited day and night and in order to attain good cultivation results the hothouses must be heated to a suitable and uniform temperature.
  • the object of the present invention is, as will appear from the foregoing, to realize a large reduction of the consumption of heat energy by bringing together the plants by simple means and maintaining them within a partitioned-off and heated area of the hothouse during
  • the apparatus comprises a plurality of posts driven into the ground on a straight line longitudinally of the hothouse and spaced a couple of meters apart, and an equal number of posts driven into the ground along a parallel line, all of said posts being provided with an upper and a lower, fixedly arranged rotatable wheel, each of said upper and lower wheels being adapted to carry a panel or plant table top and said plant table tops being longitudinally movable.
  • each panel or plant table top corresponds to - approximately half the length of the hothouse.
  • the panels or plant table tops are driven and operated electrically in both longitudinal directions.
  • the height distance beween the plant table tops corresponds to the heights of a full-grown pot-plant and can thus vary according to different plant species.
  • each row of stationary plant tables there are provided at the so-called work passages posts carrying wheels. These posts are also arranged along straight parallel lines in the other half of the hot- house. These posts with their wheels carry the movable plant tables which in the daytime are stationed in one half of the hothouse, that is that part of the houthouse which is devoid of stationary plant tables. In the night ⁇ time the movable plant tables with the plants thereon are moved in between the stationary plant tables to bring the plants together in the heated part of the hothouse.
  • Fig. 1 is a perspective view of an apparatus accord- ing to the invention, in which the two plant table tops are moved into superimposed relation and occupy the posx- tion which the plant table tops with the plants thereon shall occupy in the partitioned-off and heated hothouse area in the night-timey
  • Fig. 2 is a perspective view of the plant table top in protracted position, in which the lower table top is entirely protracted to the position in which the apparatus shall function in the daytime;
  • Fig. 3 is a diagrammatic plan view of the location of the plant tables in a hothouse where use is made of alternately stationary and movable plant tables.
  • the full lines designate stationary plant tables and the broken lines movable plant tables according to the invention.
  • the movable table tops are transferred to the other part of the hothouse, where they have been marked by full lines;
  • Fig. 4 is a diagrammatic view of the location of movable plant tables having upper and lower table tops according to the invention.
  • the right-hand part shown by full lines represents the principle according to Fig. 1
  • the part shown by full lines together with the part shown by broken lines represents the principle according to Fig. 2.
  • Fig. 1, 3 designates the posts which shall prefer ⁇ ably be embedded in the cement floor of the hothouse. Said posts 3 shall be arranged in pairs in parallel rows throughout the inner hothouse area.
  • the posts 3 are pro ⁇ vided with an upper movable wheel 4 and a lower, likewise movable wheel 6, which are secured to the posts 3 by the fastenings 5 and 7.
  • These wheels 4 and 5 serve as movable holders for the table tops 1 and 2, the upper wheels 4 being holders for the upper table top 1 and the lower wheels 6 being holders for the lower table
  • the table tops 1 and 2 extend longitudinally of the hothouse and are provided in the outer parts of their lower sides with parallel grooves 8 which serve as guides for the wheels 4 and 6 at the movements of the table tops 1 and 2 in the two longitudinal directions.
  • the movements of the table tops 1 and 2 shall preferably be realized by means of electric motors and all plant tables are operated simultaneously by controls, if use is made of several different rows of such tables, but it shall also be possible for certain controls to operate each table top separately.
  • the part of the hothouse to be heated in the night-time should suitably be parti ⁇ tioned-off with the aid of special Venetian blinds or like means. Fig.
  • FIG. 1 shows the table tops 1 and 2 rolled to their end positions within the heated area of the hothouse, as shown by full lines in Fig. 4.
  • 13 designates the spaces for work and transport passages.
  • 10 designates the stationary plant tables which are placed within that area of the hothouse which is to be heated in the night ⁇ time.
  • 11 designates the movable plant tables and 14 the spaces for work and transport passages. In the night-time the table top 11 is moved over to the heated part of the hothouse into the passage 14 to position 12, etc.

Abstract

Dispositifs mobiles sous forme de tables pour plantes (1, 2) destines a etre utilises dans des serres et des locaux analogues dans le but de permettre le deplacement des plantes, par exemple pendant l'annee, dans une zone adjacente, separee et chauffee de la serre, permettant ainsi de realiser des economies d'energie en concentrant la chaleur necessaire a une partie reduite des locaux. Les tables pour plantes sont concues de maniere a pouvoir etre poussees vers la zone chauffee l'une sur l'autre ou cote a cote, les plantes restant sur les tables, et a pouvoir etre ensuite redistribuees dans toute la serre pendant le jour et le temps de la croissance pour la culture, la recolte et l'emballage.
