Detailed Description
The following specific examples are intended to be illustrative of the utility model and are not intended to be limiting, as modifications of the utility model will be apparent to those skilled in the art upon reading the specification without inventive contribution thereto, and are intended to be protected by the patent law within the scope of the appended claims.
The scheme is realized by the following technical means:
example 1: in this embodiment, a plant three-dimensional cultivation system is provided, which can realize continuous cyclic movement of a carrying tray 1 with a plurality of different positions for cultivating plants on a three-dimensional conveying and transporting frame 2 so as to reduce the difference degree of sunlight exposure of the plants in each carrying tray 1, and the system mainly comprises two parts, namely the carrying tray 1 for carrying the plants and the substrates for cultivating the plants, and the three-dimensional conveying and transporting frame 2 for realizing continuous cyclic movement of the carrying tray 1 at different horizontal and height positions.
For the bearing tray 1, specifically, the bearing tray 1 includes a tray main body, and the tray main bodies are connected with each other by using steel materials with an L-shaped cross section and are connected by welding to form a main frame 1a with an overall shape of a Chinese character kou. Since the L-shaped steel material used as the raw material includes a portion extending in the horizontal direction and a portion extending in the vertical direction, an upwardly protruding lateral abutment portion 101 is formed on the upper surface of the main frame portion 1a, and a centrally extending bottom surface receiving portion 102 is formed on the inner side surface of the main frame portion 1a. At this time, the lateral abutting portion 101 and the bottom supporting portion 102 formed on the main frame portion 1a may surround and form an upwardly open accommodating cavity 11, a panel made of foam material or hollow structure may be placed in the accommodating cavity 11, and then a substrate such as soil or granular sand with different sizes for fixing and culturing plants may be laid on the panel, and the plant is fixed therein. With this structure, the bottom supporting portion 102 performs a bearing function on plants, substrates and panels thereon, and the lateral abutting portion 101 can peripherally surround the substrates and panels, so as to define the positions of the panels and prevent the substrates from falling out. Further, an L-shaped steel material with an inclined side abutting portion 101 extending upward may be selected, so that the enclosed accommodating cavity 11 has a shape structure with a large top and a small bottom, and the panel between the bottom supporting portion 102 and the substrate may be more stably and accurately fixed during installation.
Considering that when water or other nutrient solution is added into the matrix, the condition that the matrix can be fixed is exceeded, the bottom of the tray main body is not completely sealed, but a through opening which penetrates up and down is formed, so that excessive water or nutrient solution can be discharged outwards, and the rot of the plant root is avoided. Because the base plate adopts foam material or fretwork shape material to make, have more spaces, consequently this switch-on opening can also cooperate with the base plate, ensures that the matrix has good gas permeability, promotes the growth of plant. Considering that the weight of plants and substrates is large, a pressure panel may occur, and thus an auxiliary supporting rib connected between opposite side wall surfaces is further provided at a central position of the bottom of the tray, so that the lower portion of the tray body takes a grid-like structure.
The two sides of the main body of the bearing tray 1 are symmetrically and fixedly provided with the connecting parts 1b protruding upwards, and the distance between the installation position points between the two connecting parts 1b and the main body of the tray is equal to the distance between the two adjacent side edges, so that the connecting line between the two connecting parts 1b is always positioned at the middle position right above the gravity center of the tray, and the main body of the tray can be ensured to be always stable in a horizontal state anyway, and the falling and overturning of plants in the bearing tray 1 or the tilting and spilling leakage of matrixes are avoided.
For the three-dimensional conveying transportation frame 2 part, the three-dimensional conveying transportation frame comprises a main frame body 2a fixedly placed on the ground, the main frame body 2a can be formed by splicing and building I-shaped steel pieces or cylindrical steel pipes, and a multi-layer structure for placing plants at different height positions is formed in the main frame body 2 a. The main frame body 2a is provided with a conveying system 3 for driving the bearing trays 1 carrying plants and matrixes needed by plant cultivation to move on the main frame body 2a so as to facilitate the cyclic reciprocating lifting and translational movement of plants at different horizontal and height positions, and the effect that the plants in each bearing tray 1 can receive the same sunlight irradiation is achieved. Specifically, the conveying system 3 further includes two parts, namely a vertical transferring unit 4 for driving the carrying tray 1 to perform lifting motion and a horizontal transferring unit 5 for performing translational motion, and the plurality of vertical transferring units 4 and the horizontal transferring unit 5 are arranged in a manner of continuously and alternately mutually and form a closed annular conveying system 3 around the carrying tray.
Specifically, the formed main frame body 2a is in a cuboid shape, and a plurality of vertical transfer units 4 and horizontal transfer units 5 are integrally arranged in the main frame body 2 a; viewed from the side, the middle portion of each height layer of the main frame body 2a is provided with a horizontal transfer unit 5 extending in the horizontal direction, and both ends of the main frame body 2a are provided with vertical transfer units 4 for connecting two adjacent horizontal transfer units 5 in the vertical direction.
Taking the example that the stereoscopic transport and transferring rack 2 for raising seedlings is divided into five height layers from bottom to top, attention should be paid to the fact that a horizontal transferring unit 5 is provided for each height layer in order to install and arrange the equipment, and when the vertical transferring unit 4 is provided, the arrangement should be made between the first and second layers located at the front end, the arrangement should be made between the second and third layers located at the rear end, the arrangement should be made between the third and fourth layers returning to the front end again, and the arrangement should be made between the fourth and fifth layers located at the rear end. With this structure, no matter which position of the main frame body 2a is used as the entrance for placing the carrying tray 1, plants can be distributed in the whole internal space of the three-dimensional conveying and transporting frame 2 through the cooperation operation of each horizontal transporting unit 5 and each vertical transporting unit 4.
In order to realize the cyclic transportation function of the bearing tray 1 and plants therein, a vertical transportation unit 4 which is lengthened in the height direction is arranged at the front end or the rear end of the main frame body 2a and is used for connecting two horizontal transportation units 5 at the highest position and the lowest position, so that all the horizontal transportation units 5 and the vertical transportation units 4 are alternately connected, and the translation conveying chain segments 5a and the lifting conveying chain segments 4a are alternately connected with each other in turn in an alternating manner, so that the conveying chain 8 forms a closed annular structure. At this time, only one driving disc driven by a motor and provided with teeth matched with the conveying chain 8 is arranged at the lower part of the conveying chain 8 in a closed ring shape, the conveying chain 8 is driven to move, so that the bearing tray 1 can be driven to move circularly through the movement of the conveying chain 8, plants in the bearing trays 1 can be observed and treated in sequence at a fixed safe position, and the device is safe and efficient.
Under this structure, will plant three-dimensional cultivation system is placed in outdoor environment, carries out the cyclic motion through motor drive conveying chain 8 with certain speed, can drive each movable mounting and carry tray 1 on conveying chain 8 and pass through each high position on the three-dimensional transport transportation frame 2 in proper order. At this time, considering that the external illumination condition is approximately stable and unchanged in the period of one motion cycle, each bearing tray 1 and plants in the bearing trays stay at a specific position on the three-dimensional conveying transportation frame 2 for the same time, so that the illumination conditions of the plants in different trays can be ensured to be approximately consistent, the influence of the illumination factor on the cultivation condition of the plants of different groups in a test state is avoided, more accurate observation and research on the growth condition of the plants are facilitated, and more reliable data are obtained.
Example 2: on the basis of the plant stereoscopic cultivation system described in embodiment 1, considering that the position of the carrying tray 1 in the horizontal direction and the vertical direction needs to be continuously changed when the carrying tray 1 is moved, a transition reversing device 6 capable of realizing smooth transition between different movement modes of the carrying tray 1 in the two-part units should be provided between the horizontal transfer unit 5 and the vertical transfer unit 4. In particular, a conveyor chain 8 formed by a plurality of link units 8a connected in a hinged manner to each other may be employed as a member for mounting the carrying tray 1 to drive its movement. Since the hinge center at the junction between the two link units 8a on the conveyor chain 8 is relatively stable with respect to the single link unit 8a, the influence on the movement of the conveyor chain 8 itself can be minimized if the carrying tray 1 is installed there. For example, a central coupling part 801 may be provided at the hinge center, which central coupling part 801 is formed by the pin position on the link unit 8a continuing to protrude toward the loading tray 1 side and is also cylindrical. The conveying chain 8 is symmetrically arranged on two sides on the main frame body 2a by taking the bearing tray 1 as a center, correspondingly, connecting parts 1b provided with circular mounting holes are formed on two sides of the bearing tray 1 for allowing cylindrical protrusions on the central connecting part 801 to pass through to form a hinge structure, and at the moment, the bearing tray 1 can be mounted on the conveying chain 8 and swings around the center of the hinge structure. The transition reversing device 6 is specifically a fluted disc which is mounted on the main frame 2a and is located at the front end or the rear end of the main frame 2a and can rotate freely, and meshing teeth on the circumference of the fluted disc can be embedded into a gap between two chain link units 8a on the conveying chain 8 and stably abutted against and attached to the gap. When the angle of the partial arc of the conveyor chain 8 around the toothed disc with respect to the centre of the toothed disc is approximately 1/4 round, the conveyor chain 8 is guided by the toothed disc as a transitional switching device 6 to separate the two functional parts for the translation conveyor chain segment 5a and the lifting conveyor chain segment 4 a. The fluted disc is arranged at the transition position of each required vertical transfer unit 4 and horizontal transfer unit 5 on the main body frame, so that the complete conveying chain 8 can be divided into a plurality of lifting conveying chain segments 4a and shifting conveying chain segments 5a, and meanwhile, each fluted disc has a stable and reliable supporting effect on the conveying chain 8. At this time, through the movement of the conveying chain 8, the position of the bearing tray 1 can be changed between the two units, and meanwhile, the balance state of the main body part of the bearing tray 1 playing a bearing role can not be damaged, so that the phenomenon that the internal plants topple or the matrix is scattered outwards in the moving process is effectively avoided.
Preferably, the circular mounting hole on the mating connection portion 1b may be downwardly opened with an open slot extending in the vertical direction, and a bottom portion of the open slot on the upper side may be still in a circular arc shape. At this time, the cylindrical protrusions on the conveying chains 8 at two sides are directly guided into the opening groove, and the bearing tray 1 can move downwards under the action of self weight until the cylindrical protrusions are abutted against the bottoms of the opening groove, so that the stable and reliable movable connection between the bearing tray 1 and the conveying chains 8, which is convenient for disassembly and assembly adjustment, is completed.
The stereoscopic conveying and transferring frame 2 for seedling raising is preferable, and because the distance between the two ends of the main frame body 2a is larger, the conveyor chain 8 and substances such as the bearing tray 1, plants, matrixes and the like on the conveyor chain 8 are supported only through a plurality of fluted discs serving as the transition reversing devices 6 at the two ends, so that the condition that the conveyor chain 8 sags to cause operation jam and even equipment damage is likely to happen. Therefore, a support rail extending in the horizontal direction is provided in the main frame body 2a at a lower position of the carrying tray so as to play a main supporting role on the carrying tray 1 in a translational state to share the acting force on the conveying chain 8. Further, in order to keep the translational conveyor chain segment 5a in the conveyor chain 8 as straight as possible, a plurality of auxiliary supporting wheels 201 for further supporting the bottom surface of the conveyor chain 8 may be mounted on the main frame 2a in a horizontal direction, or a tensioning mechanism 7 for providing a horizontal force may be mounted between the toothed plates at both ends and the main frame 2 a. The tensioning mechanism 7 comprises a spring component which is arranged along the horizontal direction, and can allow the fluted disc to reciprocate by a certain amplitude when the conveying chain 8 is subjected to the action of excessive impact, so that the damping effect is achieved, and the damage to the conveying chain 8 is avoided.
Preferably, the circular mounting hole on the mating connection portion 1b may be downwardly opened with an open slot extending in the vertical direction, and the bottom portion of the open slot may be still circular arc-shaped. At this time, the cylindrical protrusions on the conveying chains 8 at two sides are directly guided into the opening groove, and the bearing tray 1 can move downwards under the action of self weight until the cylindrical protrusions are abutted against the bottoms of the opening groove, so that the stable and reliable movable connection between the bearing tray 1 and the conveying chains 8, which is convenient for disassembly and assembly adjustment, is completed.
Further, the structure of the carrying tray 1 is preferable in that, in consideration of the fact that the carrying chain 8 carries the entire weight of the carrying tray 1 when carrying and transferring in the horizontal direction, this part of the load is unnecessary and liable to cause damage to the connecting portion 1b of the link unit 8a on the carrying chain 8 with respect to carrying and transferring in the vertical direction, and therefore, a carrying guide assembly 9 is also provided in the mechanism. The load guide assembly 9 mainly comprises a guide rail frame 9a for improving the stability of the load tray 1 when moving along the horizontal direction and supporting the bottom of the load tray 1 so as to share the acting force of the load tray on the conveying chain 8. In order to reduce friction between the seedling raising carrying tray 1 and the guide rail frame 9a, a roller assembly for reducing resistance at the time of movement is mounted on the bottom of the seedling raising carrying tray 1.
Further, since the lower part of the seedling-raising carrying tray 1 is supported by the rail frame 9a during the horizontal movement, it does not shake; in the vertical lifting and moving process, the bearing tray 1 for seedling raising is completely suspended and lifted on the conveying chain 8, and at this time, shaking inevitably occurs. Therefore, a movable lifting structure 10 is arranged between the tray main body and the connecting portion 1b, so that the tray main body can lift and move in the vertical direction relative to the connecting portion 1b, and the gravity center is far away from the connecting point after the tray is integrally moved downwards when the tray is suspended, so that the shaking amplitude in the state is effectively reduced, and the operation and conveying process is more stable. Specifically, the connecting portions 1b located at two sides of the tray main body are movably connected with the outer side faces of the tray main body, for example, a guide groove extending along the vertical direction is formed in the connecting portion 1b, and the tray main body protrudes outwards to form a guide portion penetrating through the guide groove, so that the movable mode can be achieved. In order to be more stable when the conveying chain 8 drives the seedling raising carrying tray 1 to move onto the guide rail frame 9a or separate from the guide rail frame 9a, the tray can also gradually extend downwards near the tail end of the guide rail frame 9a, so as to form a guide transition section 901 for driving the tray main body to stably lift relative to the connecting part 1b in the process of ascending or descending the tray to separate from the guide rail frame 9a.
While the utility model has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
