Below in conjunction with accompanying drawing, embodiments of the invention are further described.
As shown in Figure 2, the seedbed adopts conventional square pipe to assemble, and puts the seedbed net on the bed surface, is convenient to place cave dish or potted plant.When the seedbed is set, the width that requires the seedbed according to condition of service with the people bend over semi-girder can the easy manipulation seedbed on crop decide, length according to greenhouse length and seedbed in the greenhouse deployment scenarios and decide.In the present embodiment, the seedbed specification tentatively is defined as: long 2000 millimeters, wide 500 millimeters, high 100 millimeters.The seedbed berth planning number of plies is complied with then, and the height in greenhouse needs with actual plantation and decides, every interlamellar spacing is according to the design of plant intolerance of shade, and the present embodiment berth is planned to three layers, and longitudinal pitch is made as 300 millimeters, the berth transverse pitch is 20 millimeters, has improved cultivated area and space availability ratio greatly.
As shown in Figure 3, vertical track 17 left and right sides are raised brim, move up and down along it for the track adjusting wheel 3 on the carriage 14, and in the present embodiment, track adjusting wheel 3 adopts rubber rolls, with reduce and vertical track 17 between friction.Quantity and the spacing setting of determining hole 4 according to fore-and-aft distance and the number of plies of the planning of above-mentioned seedbed berth on the vertical guide rail 17, hole 4 quantity equate with the berth number of plies at least.In the present embodiment, beaten 7 holes 4 on the vertical guide rail 17, each hole be spaced apart 100 millimeters, then three of carriage shown in the figure 14 positions are first, second and third layer position of berth correspondence.The ascending velocity of setting the seedbed is 0.8 meter per second, and then electromagnetic braking brake deceleration motor 8 selection power are the electromagnetic braking brake deceleration motor that applies to lifting transportation occasion of 3kw.The LOAD CELLS selected range is the LOAD CELLS of 500kg.
As shown in Figure 4, the three-high berth position all is fixedly mounted on the assigned position place in greenhouse by the transverse and longitudinal spacing of setting, berth is planned to 9 districts, is numbered among the figure 1,2,3,4,5,6,7,8,9.At berth the transverse axis of being controlled lifting by air cylinder is installed, the length of transverse axis is shorter than the width in each seedbed slightly, is convenient to lifting.Simultaneously install push pedal chain-type driver train on limit, the leftmost side and the limit, the rightmost side of every layer of berth, be used for to promote the seedbed on horizontal surface to the right or be moved to the left, this horizontal logistics system only is used for the mobile successively of seedbed, namely the berth district of process be the room district, if not the room district, namely to move on to desired location to the seedbed that hinders previously earlier.
In this example, suppose to have only 2 districts that the seedbed is arranged, all the other are vacant berth, and the demonstration seedbed is described below from the process that 2 districts move to 7 districts:
At first rise the every transverse axis in ground floor (1,2,3 district), make it on same horizontal surface, then this moment the seedbed by frame on transverse axis.The lifting structure of space, three-dimensional seedbed logistics system is fixed on the ground in whole berth left side, makes the distance 5～10mm of carriage 14 and berth, be convenient to carriage 14 and dock with the transverse axis of berth.Open the master cock of electromagnetic braking brake deceleration motor 8 in the control housing, make the carriage 14 of lifting structure be down to the transverse axis that rises with 3 districts berths and align, the master cock of disconnection electromagnetic braking brake deceleration motor 8 is locked in carriage 14 on this height.Start the push pedal chain-type driver train of the ground floor leftmost side, when push pedal moved to right side, seedbed, 2 district, the transverse axis that rise in its effect lower edge in the seedbed moved to 3 districts, because carriage 14 and 3 districts are horizontal
AxleButt joint, then the seedbed continues to be moved on the carriage 14, shown in Fig. 4 (a).When whole seedbed steadily is placed on the carriage 14, LOAD CELLS 2 receives measurable electric signal, and whether detect the seedbed overweight, then sends overweight signal as overweight, manually takes off part cave dish or potted plant.Forward is opened electromagnetic braking brake deceleration motor 8 master cocies of lifting structure then, driving driving chain sprocket 5 after electromagnetic braking brake deceleration motor 8 slows down rotates, driving chain sprocket 5 drives conduction chain 10 and moves up, because conduction chain 10 is connected with the carriage 14 that the seedbed is housed, the carriage 14 that the seedbed is housed rises to the left side, 4 districts of the second layer.When position transduser 11 receives electrical signal detection to carriage 14 during by the hole 4 on the vertical guide rail 17 of second layer berth correspondence, control unit 1 sends signal and reduces electromagnetic braking brake deceleration motor 8 rotating speeds, makes the seedbed slowly near the 3rd layer.During the vertical guide rail upper opening by three-high berth position correspondence, disconnect the master cock of electromagnetic braking brake deceleration motor 8 in the control housing to carriage when position transduser 11 receives electrical signal detection, make the carriage that the seedbed is housed be still in the 3rd layer.The every transverse axis that rise the 3rd floor (7,8,9 district) this moment docks carriage with 9 district's transverse axis.Open the master cock of air lift pump 15 in the control housing, the air pressure manipulator system that then is installed on the carriage is activated, and the seedbed is pushed on 9 district's berths from carriage, shown in Fig. 4 (b).Start the push pedal chain-type driver train of the leftmost side, three-high berth position, the seedbed is moved to 7 districts along transverse axis, fall the 3rd layer of transverse axis, last seedbed is accurately dropped on 7 district's berths.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and not breaking away from the improvement that category of the present invention makes and revise all should be within protection scope of the present invention.
