CULTIVATING APPARATUS
This invention relates to a cultivating system, more particularly to an improved cultivating apparatus which comprises a conveyor to hold and shift a plurality of sowing pans.
Some solution-culture plants, such as vegetables, are cultivated and protected in greenhouses. In this way, the vegetables are prevented from being damaged by pests without using insecticides. These vegetables are popular because they are nonpoisonous and sanitary.
The solution-culture sowing pans are generally arranged in a single layer or in a multi-layer wherein an upper sowing pan does not cover a lower sowing pan so that the plants can obtain sufficient light for photosynthesis. Therefore, the maximum sowing pan space is limited by the available floor area.
On the other hand, some sowing pans are fixedly stacked in a multi-layer arrangement wherein the sowing pans overlap one another so as to utilize the floor area sufficiently. However, there are drawbacks to this arrangement: a lower sowing pan ordinarily cannot obtain sufficient light for photosynthesis.
Furthermore, the lower sowing pan usually receives excess water and fertilizer dropped from an upper --2-- ~55~3 sowing pan, thereby increasing the chance that plants cultivated thereat rot Because the sowing pans are fixedly stacked, there must be many passageways for people to place and remove plants from the sowing pans.
Thus, such an arrangement utilizes much space and is not economical.
Therefore, a feature of this invention is to provide an improved cultivating apparatus with a moving mechanism to move a plurality of sowing pans so that the sowing pans can be interchanged from a lower position to an upper position or vice versa for sufficient exposure to light: for photosynthesis or for receiving care such as watering, fertilizing, etc.
Another feature of this; invention is to provide a three-dimensional cultivating apparatus with a plurality of sowing pans mechanically movable to a desired location so that the passageways needed for workmen to handle plants in the sowing pans can be minimized and the space required is reduced.
Accordingly, a cultivating apparatus of this invention includes a supporting frame having a top, a bottom and two opposite sides and a plurality of pairs of coaxial wheel members where each of the pairs of coaxial wheel members are respectively mounted to the opposite sides. A driving means is connected to the wheel members to rotate the wheel members. Two I
opposite endless elongated conveying members are trained on the wheel members respectively on the opposite sides. Each of the two conveying members moves alternatingly upwards and downwards between the top and the bottom and extends a certain length in a lower horizontal position adjacent to the bottom.
A plurality of sowing pans are movably and removably mounted between the two conveying members at intervals. The sowing pans are arranged in terraced I rows between the top and the bottom and a horizontal row adjacent to the bottom.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:

Two opposite endless sprocket chains (34) are respectively trained on the first, second and third sprocket wheels (31, 32, 33). Each of the two sprocket chains (34) moves alternatingly upwards and downwards in a wavy fashion between the horizontal upper and lower bars (14, 16) and extends a certain horizontal length below the horizontal lower bar (16). A plurality ox sowing pans ~40) are movably and removably mounted between the two sprocket chains (34) at intervals. The sowing pans (40) are arranged in terraced rows (35) between the horizontal upper and lower bars (14, 16) and a horizontal row (36~ below the horizontal lower bar (16).
Two elongated U-shaped support members (37) are respectively connected to the horizontal lower bars (16) to provide guide rails for receiving the sprocket chains (34) so that the sprocket chains (34) can be kept substantially straight when they are moved under the horizontal lower bars (16). A spraying device (70) is located below the horizontal row (36) of the sowing pans (40) to spray liquids, including water and fertilizer, upwards onto the horizontal row (36) of the sowing pans (40). A controlling means (600) is connected to the driving means So and to the spraying device ~70) to control the movement of the sprocket chains (34) and the operation of the spraying device (70), respectively.
Referring to figure 4, each of the sowing pans (40) is substantially rectangular and has two opposite transverse end plates (42) and three interconnected gridiron modules (42') forming a U-shaped channel between the end plates (42). Each of the gridiron modules (42') has two opposite longitudinal flank portions (43) and a base portion (44) welded to the two flank portions (43). Each of the flank portions (43) has two ends respectively welded with two connecting plates (431). Each of the connecting plates (431) has three screw holes (aye) formed thereon. The connecting plates (431) of each of the gridiron modules (42') are screwed to the connecting plates (431) of an adjacent one of the gridiron modules (42') by means of screws (45) and nuts. Each of the end plats (42) has screw holes to be screwed to the connecting plates of one of the gridiron modules (42') by means of screws and nuts. Additional gridiron modules (42') can be provided in order to increase the length of the sowing pan (40). Each of the end plates ~42) has a hanging I
cord (41) attached thereto.
Referring to Figures 5 and 6, each of the sprocket chains (34) has a plurality of pairs of chain pins (341) radially extending therefrom, a plurality of pairs of cylindrical members (381) respectively sleeved on the chain pins (34), and a plurality of pan mounting units t38).

Referring to Figure 7, each of the sowing pans (40) has a corrugated gridiron (90) therein to define rows of grooves (90'). Each of the grooves (90') receives a root retaining medium such as gravel. Plants are cultivated on the gravel. Referring to Figures 2 and 3 again, each of the plants on the terraced rows (35) of the sowing pans (40) can obtain sufficient light when the sprocket chains (34) are actuated by the controlling means (600) to circulate at a desired speed. The spraying device (70) is simultaneously actuated by the controlling means (600) to upwardly spray liquids onto the horizontal row (36) OX the sowing pans (4 0). The sowing pans (4 0) on the horizontal row (36) are moved upward to the terraced I
rows ~35) after the water and fertilizer sprayed thereon stop dripping. This prevents the lower sowing pans (40) from receiving water or fertilizer drippings from the upper sowing pans (40). Therefore, all of the plants which are cultivated in the cultivating apparatus of this invention can obtain sufficient light and the proper balance of water and fertilizer.
Since the sprocket chains (34) can move the sowing pans (40) to a desired location, a workman who enters the greenhouse (15) by the door (21) may work on every sowing pan (40) without changing positions. Therefore, the passageways needed for the workman to work as in prior arts can be eliminated, and the space required is reduced.
The cultivating apparatus of this invention can further include a netted sun-shield member provided on the greenhouse (15) to cultivate plants which should be cultivated in a darker environment. Furthermore, referring to Figure 8, the sowing pan (40) may be lined with a liquid proof plastic sheet (80) to retain a nutrient solution Luke) so as to cultivate a solution-culture plant therein.
While the present invention has been described in connection with what is considered the must practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment, but is intended to cover various arrangements included _ 9__ 2~s~3 within the spirit and scope of the broadest interpretations and equivalent arrangements.
