Abstract

The present application relates to the technical field of forage water culture device, in particular to a three-dimensional circulation type forage water culture device, which comprises a bearing mechanism, a control mechanism installed on the bearing mechanism and a water culture mechanism installed on the control mechanism. The bottom shell is fixed to the bottom of the containing assembly by combined bolts, and a screw rod is arranged at the bottom of the bottom shell to stabilize the horizontal movement of the protective main shell plate. When the outer end of the screw rod rotates counterclockwise, the protective main shell plate will extend outward along the outer part of the screw rod until it provides stretching to the horizontal plate under the auxiliary traction of the two reset pullers and the reinforcing tension springs. Finally, the window door plate can cooperate with the two cables and the optional defroster to provide a rated growth environment for the seed storage tray.

When it is necessary to adjust the horizontal movement of the load-bearing outer frame 210 along the sliding grooves in the inside of the adjacent two tracks 150, the stretching of the two traction rods 160 outward can be controlled to realize the horizontal stretching of the load-bearing outer frame 210 and the plurality of fixed water culture mechanisms 300, so as to ensure that the plurality of water culture mechanisms 300 storing the water culture tray can fully receive the light source in the rated space, thereby reducing the energy consumption.

[0045] Embodiment 3:

[0046] In combination Figures 7-11 As shown in the embodiment, the window door plate 381 and the defogger 400 are both made of transparent glass.

[0047] According to the number of top shell 311, two fender 400 are arranged outside the outermost two top shell 311, and the two fender 400 are fixed to the outermost two protective main shell plate 350. At this time, the water culture tray provides an independent production environment for the pasture in the water culture tray, so as to avoid the water mist from spreading to the environment outside the water culture tray, and to ensure that the environment outside the water culture equipment can be kept dry and clean, and to avoid the problem of excessive humidity in the room.

[0048] Embodiment 4:

[0049] In combination Figures 6-11 As shown in embodiment one, the screw rod 330 is composed of a lengthened threaded rod, an eccentric turntable, a handle, a washer and a bolt, and the washer is fixed and installed on one end of the lengthened threaded rod away from the eccentric turntable by the bolt, and the handle is movably installed on the outer side of the eccentric turntable away from the center, the inner side of the protective main shell plate 350 and the bottom of the horizontal plate 360 are respectively provided with clamping seats distributed in the horizontal direction, and one end of the reset pull piece 370 penetrates into the clamping seat on the inner side of the protective main shell plate 350 and is fixed by the bolt, and the rod body of the reset pull piece 370 penetrating into the clamping seat on the bottom of the horizontal plate 360 is connected with a reinforcing tension spring, and the bottom of the horizontal plate 360 is provided with two U-shaped sheaths, and the horizontal plate 360 bottom clamping seat and the reinforcing tension spring are located inside the U-shaped sheath.

[0050] One end of the lengthened threaded rod is movably installed in the horizontal hole at the bottom of the backing plate, and the washer and the bolt are installed at one end of the lengthened threaded rod away from the eccentric turntable, so that the end plate at the bottom of the protective main shell plate 350 can be movably installed on the lengthened threaded rod to stabilize the horizontal movement, and the washer fixed on the lengthened threaded rod by the bolt can also avoid the problem of falling off of the end plate at the bottom of the protective main shell plate 350. At this time, the combined protective main shell plate 350, window door plate 381 and two reset pull pieces 370 can provide stable pushing force, and the butt joint of the rectangular groove at the top of the horizontal plate 360 and the top plate slot of the protective main shell plate 350 can be protected by the two U-shaped sheaths. The two reset pull pieces 370 protected by the two U-shaped sheaths can provide stable support force for the horizontal movement of the protective main shell plate 350 under the elastic support force of the reinforcing tension spring, and the two cables 383 can provide the traction force for the lateral turning of the window door plate 381 by the horizontal movement of the protective main shell plate 350. At this time, the device can not only facilitate the quick loading and unloading of the pasture tray, but also can avoid the overflow of the water mist from the space inside the protective main shell plate 350, the window door plate 381 and the fender 400.

[0051] The working principle and use process of the present application: two vertical plates 382 are fixed and installed on the two side walls of the top shell 311 by bolts in advance, and the gasket 312 is fixed and installed on the inner side of the top shell 311, then the window door plate 381 and the horizontal plate 360 are movably installed between the two vertical plates 382 by the insertion rod, then the outer ends of the two reset pullers 370 are fixed on the clamping seat on the inner side of the protective main shell plate 350 by bolts, and the ends of the two reset pullers 370 away from the protective main shell plate 350 movably penetrate into the clamping seat at the bottom of the horizontal plate 360, at this time, the two reset pullers 370 are connected between the clamping seats at the bottom of the horizontal plate 360 by two reinforcing tension springs, and the two reinforcing tension springs are located in the two U-shaped sheaths at the bottom of the horizontal plate 360, then the water supply pipe 341 is installed in the gap between the inner sides of the top shell 311 and the bottom shell 320, the end of the bottom of the shunt conduit 342 is movably installed in the inner cavity of the water supply pipe 341, and the combined sealing washer 344 and the two covers 343 are fixed and installed on the end of the L-shaped end pipe at the bottom of the water supply pipe 341 by bolts, and the top end of the L-shaped end pipe penetrates into the inner side of the protective main shell plate 350, at this time, the end plate at the bottom of the protective main shell plate 350 is movably installed outside the lead screw 330, and the lead screw 330 fixed on the bottom of the bottom shell 320 by the pad can provide stable transmission force for the horizontal movement of the protective main shell plate 350, and the end of the lead screw 330 away from the pad is connected with the washer and the bolt preventing the protective main shell plate 350 from being separated, then a plurality of top shells 311 are movably assembled with a plurality of end columns 270 by a plurality of end rods, and the plurality of end columns 270 can lift the three groups of water culture mechanisms 300 in a fixed state to the top of the load-bearing outer frame 210.

[0052] When the device is put into a sunlight greenhouse or a continuous greenhouse, and an old factory building with additional light supplementing lamps, as the device like Figure 1When the middle state is used, the operator needs to connect the external water supply pipeline with the outer end of the water conveying pipe 341 in advance, and then control the grip at the outer end of the lead screw 330 to rotate counterclockwise. At this time, the protective main shell plate 350 can expand outward along the lead screw 330. With the expansion of the protective main shell plate 350 outward from the top of the top housing 311, the horizontal plate 360 connected by the two reset tensioners 370 and the reinforcing tension spring can provide a slight side overturning thrust to the window door plate 381, while cooperating with the two cable 383 to fix the protective main shell plate 350 and the window door plate 381. At this time, the window door plate 381 can be side overturned when the protective main shell plate 350 expands to the maximum state. Then install the atomizing nozzle on the end pipe of the shunt conduit 342 penetrating into the inside of the protective main shell plate 350, and then place the seed storage tray inside the top housing 311 and the cushion 312. Then rotate the grip at the outer end of the control lead screw 330 clockwise until the protective main shell plate 350 and the window door plate 381 can quickly reset. At this time, the protective main shell plate 350, the window door plate 381 and the horizontal plate 360 can cooperate with the optional fog baffle 400 to provide the seed storage tray with an inherent growth environment. The water mist sprayed by the nozzle will always diffuse in the rated space, and will not interfere with the environment outside the seed storage tray. According to the arrangement of the device in a specific space, the operator needs to preset the length of the load-bearing outer frame 210 in advance to ensure the controllable number of water culture mechanisms 300 assembled, and the support plate 140 and the track 150 can be optionally installed in the same vertical direction.

[0053] When it is necessary to improve the growth state of the observed water culture plants, the operator can also choose to adjust the two screw discs 220. At this time, the two first core rods 230 will contract or expand horizontally inside the two screw discs 220 until the multiple end columns 270 fixed by the cross bar 280 provide inclined support for the top housing 311. At this time, the seed storage tray can adjust the angle of its inclined placement according to the operation and observation needs to facilitate the operator to monitor quickly while walking along the equipment. According to the light in the sunlight greenhouse or the multi-span greenhouse and the added light supplementing lamp in the abandoned factory building, the operator can also reversely expand the two traction rods 160 distributed vertically. At this time, the two load-bearing outer frames 210 distributed vertically can form a ladder structure. At this time, the two load-bearing outer frames 210 staggered in position can provide full light for the seed storage trays in multiple water culture mechanisms 300, and also facilitate the efficient operation of the operator in the rated space.

[0054] Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and scope of the application, which are defined by the claims and their equivalents.
