Description

Technical Field

[0001] The invention relates to a seed and seedling cultivation technology, in particular to a soilless cultivation stacked integrated planting device. Background Art

[0002] As is known to all, soilless cultivation technology has become the main cultivation technology for greenhouse cultivation due to its sterile and low-cost characteristics. Soilless cultivation is mostly achieved in greenhouses, that is, the roots of vegetables are placed in a substrate, and the substrate is filled with nutrients by irrigation with nutrient solution. The vegetables then absorb the nutrients to achieve vegetable cultivation.

[0003] The shortcoming of the prior art is that when using the existing soilless cultivation stacked integrated planting device, there is a problem, that is, the planting tray placed in the middle position of the planting rack cannot be taken out individually. In the traditional planting rack design, the planting tray can usually only be fed in from one end and taken out from the other end. This design makes it necessary for the operator to take out all the planting trays in front of it one by one when it is necessary to spot check, redistribute or deal with abnormal planting trays planted in the middle position. The operation process is cumbersome and inefficient. Therefore, how to achieve separate operation of the planting tray in the middle position of the planting rack without interfering with other planting trays has become a technical problem that needs to be solved urgently in the current soilless cultivation stacked integrated planting device. Summary of the invention

[0004] The purpose of the present invention is to provide a soilless culture stacked integrated planting device to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: comprising: a multi-layered planting frame for soilless stacking cultivation of seeds and seedlings to be cultivated, wherein a plurality of groups of crossbeams are arranged in the planting frame for support to improve the firmness of the planting frame, and a plurality of independent conveying members are installed in the planting frame for automatically conveying the planting trays of the seeds and seedlings to be cultivated in the planting frame;

[0006] The conveying members are arranged in multiple layers and are independent of each other. The conveying members installed on each layer are arranged in multiple groups, and each group of conveying members is composed of a main rail and an adjustment rail. One end of the adjustment rail in each group of conveying members that is rotatably connected to the main rail is the rotation end, and the other end of the adjustment rail that is detachably connected to the main rail arranged in the previous group of conveying members is the conveying end.

[0007] A rotating structure is provided at the connection between the main rail and the adjusting rail in each group of the conveying members, which facilitates the downward rotation of one end of the adjusting rail. The adjusting rail is rotated to rotate the conveying end of the adjusting rail downward to contact the surface of the conveying member of the lower layer, thereby directly transmitting the planting trays conveyed on the conveying member of the lower layer to the upper layer, thereby realizing the early removal of the planting trays with problems in the middle position of the planting rack, the redistribution and random inspection of the planting trays, etc.

[0008] As a further description of the above technical solution: when the conveying member is arranged on the inner side of the column of the planting rack and the planting rack will not restrict the displacement of the movable frame at the bottom of the beam, a group of movable frames is arranged on each layer of the conveying member, and when the conveying member is arranged between the columns of the planting rack, the columns in the planting rack will restrict the movement of the movable frame. At this time, a group of movable frames is arranged between every two groups of columns to realize the sliding of the movable frame on the surface of the conveying member and to rotate and adjust the adjustment guide rail in the conveying member.

[0009] As a further description of the above technical solution: the movable structure includes a plurality of conveying members composed of a main rail and an adjusting rail, and a movable frame that slides on the conveying members and the surface of the beam. The sliding of the movable frame on the beam, the main rail and the adjusting rail connects the interference structures adaptively arranged on both sides of the movable frame and the main rail, and rotates and adjusts the adjusting rails at the corresponding positions.

[0010] The movable structure includes a main rail and an adjusting rail in an upper and lower multi-layer structure, a conveying member is formed between each main rail and the adjusting rail, and the main rail and the adjusting rail are rotatably connected. A sliding track is provided at the bottom of the beam, and a movable frame is connected to the sliding track through roller sliding. The movable frame is L-shaped to adapt to the position between the beam and the conveying member, and the beam and the conveying member are connected through the movable frame. A movable groove with a size matching the main rail and the adjusting rail is provided at the position where the bottom of the movable frame is connected to the conveying member, and interference structures matching the two sides of the main rail are provided on both sides of the movable groove.

[0011] As a further description of the above technical solution: the interference structure is arranged on both sides of the connection between the movable frame and the conveying member, and the transmission blocks arranged on both sides of the bottom end of the movable frame are connected with the surfaces of the rotating columns arranged on both sides of one end of the main guide rail by sliding and contacting each other. When the limiting structure is contracted, the restriction on the rotating column is released, and at the same time, the power generated by the servo motor installed in the movable frame is transmitted to the conveying member through the transmission structure, thereby providing a power source for the rotation of the adjusting guide rail.

[0012] The interference structure includes transmission blocks arranged on both sides of the movable groove, and the transmission blocks are arranged to have an isosceles trapezoidal cross-section. The transmission block arranged on one side of the movable groove is connected through a bearing, and the transmission block on the other side is installed through the transmission structure. The transmission block is slidably connected to both sides of the main rail and the adjustment rail and is in contact with an elastic sheet arranged on the surface of the rotating column. The elastic sheet is recessed into the rotating column and fixedly connected to the interference plate. The bottom end of the interference plate is connected to the inner side wall of the bottom end of the rotating column through a reset spring, so that the elastic sheet contracts into the rotating column after being subjected to the interference extrusion force of the transmission block, driving the inward insertion of the interference plate and compressing the reset spring, and the transmission block is inserted in the position of the elastic sheet, and the rotating column is rotated in cooperation with the transmission structure.

[0013] As a further description of the above technical solution: the transmission structure is installed at the bottom end of the movable frame, and includes a servo motor that provides a power source. The power source of the servo motor is transmitted to the rotating structure through a telescopic rod and a telescopic sleeve to realize the rotation of the adjustment guide rail.

[0014] The transmission structure includes a servo motor arranged in a movable frame for providing a power source for the rotation of the adjusting guide rail. The power output end at the top of the servo motor is fixedly connected to the telescopic sleeve. The telescopic rod is telescopically plugged into the telescopic sleeve through an electric push rod. The telescopic rod is plugged into the telescopic sleeve and fixedly connected to limit plates on both sides. The limit plates are slidably connected to limit grooves on both side walls of the telescopic sleeve, so that the telescopic rod can be extended and retracted in the telescopic sleeve through the extension and retraction of the electric push rod. At the same time, the rotation of the telescopic sleeve can be driven by the servo motor to drive the transmission block connected to the top of the telescopic rod to rotate under the restriction of the limit plates and the limit grooves, thereby realizing the rotation adjustment of the adjusting guide rail through the rotating structure.

[0015] As a further description of the above technical solution: the rotating structure is installed on the rotating end of the adjusting guide rail and connected with the main guide rail when rotating, so as to realize the rotation of the adjusting guide rail and at the same time be able to divide the power of the rotation into two parts: front and rear parts:

[0016] The first part: by adjusting the guide rail to rotate downward, the gear arranged in the support structure drives the meshing rack below to retract into the folding groove, thereby canceling the interference force between the top of the rack and the rotating end surface of the adjusting guide rail;

[0017] The latter part: the rotating column drives the rotating plate arranged at the rotating end of the adjusting guide rail to rotate in the rotating groove of the main guide rail, so as to realize the downward rotation of the conveying end of the adjusting guide rail.

[0018] The rotating structure includes a transmission rod connected between two groups of rotating columns. The rotating column and the transmission rod are rotatably fixedly inserted between the two groups of rotating plates and rotatably inserted in a through hole opened at one end of the main guide rail. The rotating plate is simultaneously rotatably connected in a rotating groove opened at one end of the main guide rail. The rotating column is rotatably connected in the through hole through inner and outer ring bearings, thereby realizing the rotation of the rotating column and driving the rotation of the adjusting guide rail through the transmission rod and the rotating plate.

[0019] As a further description of the above technical solution: a limiting structure is arranged in the rotating column, which is used to cooperate with the interference connection between the transmission block arranged in the interference structure to provide restriction or release on the rotation of the rotating column in the through hole, thereby realizing auxiliary restriction on the adjustment guide rail during daily conveying work.

[0020] The limiting structure includes a resistance slideway provided on both sides of the tapered resistance plate, a sliding ball slidably connected in the resistance slideway, and the sliding ball is arranged at the bottom end of the limiting rod, and the top end of the limiting rod passes through the outside of the rotating column and is detachably inserted in the limiting hole provided on the inner side wall of the through hole, and the bottom end of the limiting rod is connected to the inner side wall of the rotating column through a buffer spring, and the change of its own size is utilized by sliding the tapered resistance plate, and the sliding of the sliding ball in the resistance slideway is cooperated to realize the insertion and withdrawal of the limiting rod in the rotating column, and the rotating column is limited by the limiting rod being inserted in the limiting hole. At the same time, the limiting rod can be pulled out of the limiting hole to rotate the rotating column to realize the rotation adjustment of the adjusting guide rail, and the surface of the rotating column away from the limiting rod is recessed inwardly and is connected to the card ball through the limiting spring, and the card ball is slidably carded in the card hole provided on the inner side wall of the through hole, so as to provide an auxiliary limiting effect for the rotating column.

[0021] As a further description of the above technical solution: the supporting structure includes a rack whose top end abuts against the bottom of the rotating end surface of the adjusting guide rail for fixed support, thereby limiting the position of the adjusting guide rail in daily horizontal conveying work.

[0022] The supporting structure includes a gear rotatably mounted on the surface of the transmission rod through a one-way bearing, a rack meshingly connected to the bottom of the gear, and the rack is slidably inserted in a folding groove through a compression spring. The folding groove is arranged at the bottom of one end of the main rail rotationally connected to the adjusting guide rail. The one-way gear can only rotate clockwise, and will be stuck and unable to rotate when rotating counterclockwise. When the adjusting guide rail is rotated counterclockwise downward, the gear and the transmission rod are rotated counterclockwise synchronously to drive the gear to mesh with the rack arranged below, and when the adjusting guide rail is lifted upward, it can rotate clockwise and will not limit the upward lifting and rotation movement of the adjusting gear.

[0023] As a further description of the above technical solution: the material guiding structure is arranged at the conveying end of the adjusting guide rail and is arranged to have a triangular cross-section, so as to be able to rotate to the surface of the lower conveying member at the conveying end of the adjusting guide rail, and cooperate with the material guiding structure to convey the planting tray along the adjusting guide rail to the surface of the upper conveying member.

[0024] The material guiding structure comprises a material guiding plate and an elastic guide plate with a triangular cross section arranged at the conveying end of the adjusting guide rail, so that the top end of the adjusting guide rail is placed on the surface of the conveying member of the next layer and the planting tray can be conveyed upward without hindrance.

[0025] In the above technical scheme, the present invention provides a soilless cultivation stacked integrated planting device, and the barrier structure is arranged at the bottom end of the main rail surface in each group of conveying parts, so that when the adjusting rail of the latter group of connections rotates downward, the baffle is automatically popped up to block the planting trays conveyed on the surface.

[0026] The blocking structure includes a baffle plate which is telescopically installed on the surface of one end of the main rail away from the rotationally connected adjusting guide rail. The bottom end of the baffle plate is movably inserted in the main rail through an extrusion spring and is rotatably connected to one end of a lever on one side through a hinge. The lever is rotatably connected to a storage groove opened in the main rail through a rotating rod near the other end. The other end of the lever is rotatably connected to an extrusion plate through a hinge. The extrusion plate is movably installed on the top of the storage groove. A material guide plate and an elastic guide plate arranged at the conveying end of the adjusting guide rail are detachably inserted in the storage groove. The material guide plate and the elastic guide plate squeeze the extrusion plate in the storage groove, and the baffle plate is driven to descend in the main rail by the lever. At the same time, when the adjusting guide rail is rotated and lowered, the material guide plate and the elastic guide plate release the squeezing of the extrusion plate, and cooperate with the rebound of the extrusion spring and the lever to drive the baffle plate to be lifted on the surface of the main rail, so as to block the planting disc transported on the surface of the main rail of the rotating adjusting guide rail to prevent it from falling off.

[0061] The first part: by adjusting the guide rail 9 to rotate downward, the gear 14 provided in the support structure drives the meshing rack 16 below to retract into the folding groove 19, thereby canceling the interference force between the top of the rack 16 and the rotating end surface of the adjusting guide rail 9;

[0062] The latter part: the rotation of the rotating column 8 drives the rotating plate 15 provided at the rotating end of the adjusting guide rail 9 to rotate in the rotating groove 18 of the main rail 2, so as to realize the downward rotation of the conveying end of the adjusting guide rail 9.

[0063] The rotating structure includes a transmission rod 17 connected between two groups of rotating columns 8.

[0069] The material guiding structure includes a material guiding plate 10 and an elastic guide plate 11 with a triangular cross section arranged at the conveying end of the adjusting guide rail 9, so that the top of the adjusting guide rail 9 can be placed on the surface of the conveying member of the next layer to transport the planting tray 5 upward without hindrance.

[0070] In the above technical scheme, the present invention provides a soilless cultivation stacked integrated planting device, and the barrier structure is arranged at the bottom end of the surface of the main rail 2 in each group of conveying parts, so that when the adjusting rail 9 of the latter group is rotated downward, the baffle 32 is automatically popped up to block the planting tray 5 transported on the surface.

[0071] The barrier structure includes a baffle 32 which is telescopically mounted on the surface of one end of the main rail 2 away from the rotation connection adjustment rail 9. The bottom end of the baffle 32 is movably inserted into the main rail 2 through an extrusion spring 35 and is rotatably connected to one end of a lever 37 through a hinge 36 on one side. The lever 37 is rotatably connected to a storage groove 34 opened in the main rail 2 through a rotating rod 38 near the other end. The other end of the lever 37 is rotatably connected to an extrusion plate 33 through a hinge 36. The extrusion plate 33 is movably mounted on the top of the storage groove 34. The storage groove 34 is detachably plugged with an adjustment rail 9. The material guide plate 10 and the elastic guide plate 11 arranged at the conveying end, through the material guide plate 10 and the elastic guide plate 11 squeezing the extrusion plate 33 in the storage groove 34, use the lever 37 to drive the baffle plate 32 to descend in the main rail 2. At the same time, when the adjustment guide rail 9 is rotated and lowered, the material guide plate 10 and the elastic guide plate 11 release the squeezing of the extrusion plate 33, and cooperate with the rebound of the squeezing spring 35 and the lever 37 to drive the baffle plate 32 to be lifted on the surface of the main rail 2, so as to achieve the purpose of blocking the planting tray 5 transported on the surface of the main rail 2 of the group in front of the rotating adjustment guide rail 9 to prevent it from falling off.

[0072] After the planting rack 1 is fixed and installed, and the external power supply is turned on, the seeds and seedlings to be cultivated are planted in the planting tray 5, and the planting tray 5 is transported to the surface of the conveying member at the corresponding height where it is needed to be stored by the conveying device, and the planting tray 5 is transported and stored in the planting rack 1 by starting the main rail 2 and the adjustment rail 9. Each layer in the planting rack 1 can store more planting trays 5. When the seeds and seedlings to be cultivated planted in the planting tray 5 set in the middle position are abnormal or the seeds and seedlings to be cultivated in the middle position need to be sampled and inspected, the current planting rack 1 can only load the seeds and seedlings to be cultivated from one end and unload them from the other end. When the planting tray 5 of the seeds and seedlings to be cultivated in the middle is sampled, only the planting tray 5 in the front can be transported outward until the required planting tray 5 is removed for sampling and other operations, which is inconvenient to use. In the present planting rack 1, when sampling the planting tray 5 in the middle:

[0073] The movable frame 4 of the upper layer of the planting tray 5 to be sampled is started to slide on the outside of the crossbeam 3, the main guide rail 2 and the adjusting guide rail 9, and slides to a group of main guide rails 2 and the adjusting guide rail 9 positions in front of the planting tray 5 to be sampled. The rollers 6 arranged inside the movable frame 4 roll, and the movable frame 4 slides to the corresponding position in the sliding track 12. At this time, the movable groove 7 opened at the bottom end of the movable frame 4 also slides to the corresponding position on the surface of the main guide rail 2. At this time, the transmission block 13 is inserted into the surface of the rotating column 8 arranged on both sides of the main guide rail 2, and the transmission block 13 squeezes the elastic sheet 24 arranged on the surface of the rotating column 8 to contract inwardly. At this time, the electric push rod 42 is started to extend the telescopic rod 44 outward in the telescopic sleeve 45, The transmission block 13 squeezes the elastic sheet 24, and the elastic sheet 24 bends into the rotating column 8, squeezing the contact plate 29. The contact plate 29 shrinks into the rotating column 8 and squeezes the return spring 30. At this time, the inward contraction of the contact plate 29 causes the limit rod 21 slidably connected to the contact slideways 31 on both sides of the contact plate 29 through the sliding ball 39 to slide toward the top in the contact slideway 31, so that under the limitation of the shape of the contact plate 29 itself and in cooperation with the rebound of the buffer spring 40, the limit rod 21 shrinks into the rotating column 8. At this time, the limit rod 21 shrinks from the limit hole 26 in the through hole 20 to the rotating column 8. At this time, the rotating column 8 can rotate freely in the through hole 20 under the rotation of the inner and outer ring bearings 25.

[0074] At this time, the servo motor 41 starts to rotate counterclockwise to drive the telescopic sleeve 45 to rotate. While the telescopic sleeve 45 is rotating, the telescopic rod 44 is restricted by the limiting piece 46 and the limiting groove 43 provided inside, thereby driving the telescopic rod 44 to rotate counterclockwise. The telescopic rod 44 drives the rotating column 8 and the transmission rod 17 to rotate counterclockwise through the transmission block 13 inserted in the rotating column 8. At this time, the driving force for the rotation of the transmission rod 17 is divided into two parts: the front and rear parts:

[0075] The front part drives the gear 14 to rotate counterclockwise, and drives the rack 16 meshed at the bottom of the gear 14 to shrink into the folding groove 19 in the main guide rail 2, thereby separating the top of the rack 16 from the rotating end surface of the adjusting guide rail 9, and canceling the restrictive force on the rotation of the adjusting guide rail 9;

[0076] The rear transmission rod 17 rotates counterclockwise to drive the fixedly connected rotating plate 15 to drive the adjusting guide rail 9 to rotate in the rotating groove 18 .

[0077] The conveying end of the adjusting guide rail 9 is rotated downward to lower the height and fit in front of the first layer of the planting tray 5 to be sampled. At this time, the guide plate 10 and the elastic guide plate 11 arranged at the top of the adjusting guide rail 9 will convey the planting tray 5 to the surface of the upper conveying member, so that the planting tray 5 is discharged from the surface of the upper conveying member and the planting tray 5 docking mechanism used outside the planting rack 1 is used to take out the planting tray 5;

[0078] When the conveying end of the adjusting guide rail 9 is separated from the previous group of main guide rails 2 and rotated downward, the guide plate 10 and the elastic guide plate 11 are rotated out of the storage groove 34 opened at the bottom of the main guide rail 2. At this time, the guide plate 10 and the elastic guide plate 11 lose the upward extrusion force on the extrusion plate 33, and the extrusion spring 35 will automatically rebound and slide the extrusion plate 33 downward, and cooperate with the hinge 36 and the lever 37 to make the baffle plate 32 bounce up from the bottom end of the main guide rail 2 under the rotation of the rotating rod 38, thereby blocking the bottom end surface of the main guide rail 2 with a notch at the rear, preventing the planting tray 5 from continuing to be transported on the surface of the main guide rail 2 and falling off from the notch;

[0079] After the sampling is completed, the servo motor 41 rotates clockwise to drive the adjusting guide rail 9 to rotate clockwise to lift the conveying end upward. At this time, the clockwise rotation of the transmission rod 17 causes the gear 14 installed through the one-way gear 14 to slip and rotate automatically, and will not drive the meshing and extension of the rack 16. After the adjusting guide rail 9 is completely flattened, the compression spring 22 pushes the rack 16 out of the folding groove 19 so that it contacts the rotating end surface of the adjusting guide rail 9, and cooperates with the gear 14 to limit the rack 16, thereby fixing the position of the adjusting guide rail 9;

[0080] At the same time, the electric push rod 42 contracts and inserts the telescopic rod 44 into the telescopic sleeve 45, thereby canceling the interference between the transmission block 13 and the elastic sheet 24, and cooperating with the return spring 30 to push the interference block outward. At this time, the limit rod 21 slides in the interference slideway 31 and squeezes the limit rod 21 outward, so that the limit rod 21 is inserted into the limit hole 26, and the position of the rotating column 8 is limited, thereby limiting the position of the adjusting guide rail 9;

[0081] The conveying end of the adjusting guide rail 9 shrinks into the receiving groove 34 opened at the top of the main rail 2, and the extrusion plate 33 is squeezed by the guide plate 10 and the elastic guide plate 11, so that the baffle 32 is retracted into the main rail 2 in cooperation with the lever 37, and the planting tray 5 on the surface of the main rail 2 is released. After the restriction and obstruction, the planting tray 5 can continue to be conveyed normally.

[0082] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
