Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of seedling tray conveying, and particularly relates to an automatic seedling tray conveying device. BACKGROUND

[0002] Automatic seedling raising needs to spread seeds in seedling trays, facilitates the transfer between various process steps, and the initial preparation steps mainly include soil covering, water spraying, seeding, secondary water spraying and secondary soil covering.

[0003] The above steps are generally divided into five processes in the prior art and arranged on a flow line, which not only causes the flow line to be too long and occupy a large space, but also makes it difficult to share a storage system due to the long distance between two same processes, further increasing the complexity of the equipment; therefore, the application proposes a folding line layout scheme of the flow line based on the characteristics of the above processes, which can significantly reduce the space occupation and simplify the supporting system, but how to realize the folding line movement of the rimmed seedling tray is the core problem to be solved by the application. SUMMARY

[0004] In view of the above situation, in order to overcome the defects of the prior art, the application provides an automatic seedling tray conveying device, and the folding line movement on the flow line generally needs two sets of independent driving mechanisms alternately, and since the two sets of mechanisms need to alternately contact the workpiece, at least one set of action mechanism is needed to control whether the workpiece is contacted or not; in order to simplify the above mechanism, the application first proposes a support assembly composed of a transverse shaft and a Mecanum wheel, which is no different from an ordinary roller when driven to move, but can exert a force to move the rimmed seedling tray when actively rotating, so that the folding line driving of the rimmed seedling tray is realized without too many action structures.

[0005] Furthermore, in order to automatically control the power connection and interruption of the transverse shaft without setting up machine vision and sensors and without increasing the driving unit, the application further proposes a clamping and synchronization assembly, which can automatically start to move the rimmed seedling tray when the longitudinal movement of the rimmed seedling tray is limited by the baffle, by being connected to the grooved rotating wheel and the sliding combination block through mutual clamping, thereby greatly simplifying the structure design and software control logic.

[0006] The technical scheme adopted by the application is as follows: the application provides an automatic seedling tray conveying device, which comprises a folding line transmission mechanism, an inductive fluid release mechanism and a straight line transmission mechanism, the folding line transmission mechanism is arranged at one end of the straight line transmission mechanism, and the inductive fluid release mechanism is arranged on the straight line transmission mechanism.

[0007] The folding line transmission mechanism comprises an end roller, a clamping synchronization assembly, a tension transmission assembly and a position sensing plate, the linear transmission mechanism comprises a rack, the end roller is rotatably arranged in the rack, the clamping synchronization assembly comprises a sliding combination block, a flange sleeve, a synchronization dial and a reset torsion spring, the flange sleeve is rotatably arranged on the end roller, a grooved rotating wheel is arranged on the end roller, the sliding combination block in sliding engagement with the grooved rotating wheel is clamped on the flange sleeve, the synchronization dial is rotatably arranged on the flange sleeve, the rotation of the synchronization dial can control the expansion and contraction of the sliding combination block, and the reset torsion spring is arranged between the flange sleeve and the synchronization dial.

[0008] Under the elastic force of the reset torsion spring, the synchronization dial has a tendency to expand the sliding combination block, and the sliding combination block will only be synchronously contracted when it is pressed by the transmission belt, so that the combination with the grooved rotating wheel is realized.

[0009] Further, the grooved rotating wheel is annularly and uniformly provided with a clamping groove portion, the sliding combination block is provided with a clamping boss portion matched with the clamping groove portion, the sliding combination block is further provided with a sliding strip, and the flange sleeve is provided with a sliding groove.

[0010] The sliding direction of the sliding combination block relative to the flange sleeve is limited by the limiting of the sliding groove on the sliding strip, so that the movement direction of the sliding combination block always points to the axis position of the end roller.

[0011] As preferred, the sliding strip is clamped and slid in the sliding groove, the end of the sliding strip is further provided with a dialing pin, the synchronization dial is annularly and uniformly provided with an inclined sliding groove, and the dialing pin is slidably arranged in the inclined sliding groove.

[0012] The synchronous sliding of each sliding combination block can be controlled by the annularly and uniformly distributed inclined sliding grooves, so that the external contour of the clamping synchronization assembly can be maintained in a circular shape whether it is expanded or contracted.

[0013] Further, the tension transmission assembly comprises a transmission belt, a driven wheel, a horizontal moving shaft and a Mecanum wheel, the rack is provided with a waist-shaped sliding groove, one of the horizontal moving shafts is slidably arranged in the waist-shaped sliding groove, the driven wheel is fixedly connected to the horizontal moving shaft, the transmission belt is arranged outside the sliding combination block and the driven wheel, the other of the horizontal moving shafts is rotatably arranged in the rack, and the Mecanum wheel is arranged on the horizontal moving shaft.

[0014] When the fluted seedling tray is pressed against the position sensing plate, the horizontal moving shafts and the Mecanum wheels are driven to rotate, and at this time, the fluted seedling tray moves longitudinally under the action of the linear transmission mechanism; after the fluted seedling tray is pressed against the position sensing plate, a group of horizontal moving shafts and Mecanum wheels close to the linear transmission mechanism are connected with the end roller through the clamping synchronization assembly and rotate, and at this time, the fluted seedling tray cannot continue to move longitudinally, and thus moves transversely under the drive of the Mecanum wheels until the fluted seedling tray leaves the baffle.

[0015] When the Mecanum wheels rotate, a diagonal driving force can be generated on the fluted seedling tray, and at this time, if the longitudinal movement is limited, the fluted seedling tray moves transversely.

[0016] As a further preferred embodiment of the present application, the position sensing plate comprises a sliding frame and a baffle, the sliding frame is slidably arranged on the rack, and the baffle is fixedly connected to the sliding frame; the inductive fluid release mechanism comprises a fluted seedling tray, and the fluted seedling tray and the baffle are in sliding contact.

[0017] The baffle is made of a material or coated with a coating (such as Teflon) having low friction, which can effectively reduce the sliding resistance between the fluted seedling tray and the baffle.

[0018] Further, the inductive fluid release mechanism further comprises a feeding assembly and an automatic valve assembly, the feeding assembly is arranged on the rack, and the automatic valve assembly is arranged in the feeding assembly.

[0019] As a preferred embodiment, the feeding assembly comprises a feeding support, a feeding pipe and a feeding cylinder, the feeding support is arranged on the rack, the feeding pipe is arranged in the feeding support, and the feeding cylinder is fixedly connected to the rack, and the feeding pipe and the feeding cylinder are through.

[0020] As a further preferred embodiment of the present application, the bottom of the feeding cylinder is provided with a discharging inclined opening, the automatic valve assembly comprises a plug strip, a fork frame and an inductive roller, the plug strip is slidably arranged in the discharging inclined opening, the fork frame is fixedly connected to both ends of the plug strip, and the inductive roller is rotatably arranged at the bottom of the fork frame, and the inductive roller and the edge of the fluted seedling tray are in rolling contact.

[0021] Through the cooperation of the flange on the fluted seedling tray and the inductive roller, when the storage area of the fluted seedling tray moves below the discharging inclined opening, the valve is automatically opened by the rising of the plug strip, thereby achieving the technical purpose of automatic feeding at a specified position.

[0022] Since the nutrient soil, water and seeds are all in a flowing state, the main structure of the feeding cylinder and the automatic valve assembly is similar, and only the details of the discharging inclined opening and the plug strip need to be adaptively matched.

[0023] Further, the linear transmission mechanism further comprises a conveyor belt and a transmission roller, the transmission roller is rotatably arranged in the rack, and the conveyor belt is rollingly arranged on the transmission roller.

[0024] The beneficial effects achieved by the present invention using the above structure are as follows:

[0025] (1) Under the elastic force of the reset torsion spring, the synchronous dial has a tendency to open the sliding engagement block. When the sliding engagement block is squeezed by the transmission belt, the sliding engagement block will shrink synchronously, thereby realizing the engagement with the grooved wheel.

[0026] (2) By limiting the position of the sliding bar by the sliding groove, the sliding direction of the sliding joint block relative to the flange sleeve can be limited, so that the movement direction of the sliding joint block always points to the axial position of the end roller.

[0027] (3) The synchronous sliding of each sliding joint block can be controlled by the circularly distributed inclined grooves, so that the outer contour of the locking synchronous component can be maintained in a circular shape regardless of whether it is opened or contracted.

[0028] (4) Before the flanged seedling disc touches the position sensing plate, the transverse shaft and the Mecanum wheel will rotate drivenly, and the flanged seedling disc will move longitudinally under the action of the linear transmission mechanism; after the flanged seedling disc touches the position sensing plate, a set of transverse shafts and the Mecanum wheel close to the linear transmission mechanism will establish a connection with the end roller through the engaging synchronization component and rotate. At this time, since the flanged seedling disc can no longer move longitudinally, it will move laterally under the drive of the Mecanum wheel until it leaves the baffle.

[0029] (5) The Mecanum wheel can generate an oblique driving force on the flanged seedling tray when rotating. At this time, if the longitudinal movement is restricted, the flanged seedling tray will move laterally.

[0030] (6) The baffle is made of a low-friction material or coating (such as Teflon, etc.), which can effectively reduce the sliding resistance between the edged seedling tray and the baffle.

[0031] (7) By cooperating with the flange on the fringe seedling tray and the induction roller, when the storage area of ​​the fringe seedling tray moves to the bottom of the unloading bevel, the valve is automatically opened by the rising of the plug strip, thereby achieving the technical purpose of automatic feeding at the specified position.

[0032] (8) Since the nutrient soil, water and seeds are all in a fluid state, the main structures of the feed barrel and the automatic valve assembly are similar, and only the details of the discharge bevel and the plug strip need to be adaptively matched. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0047] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0048] As shown in Figures 1-10 The present application provides an automatic seedling raising tray conveying device, which comprises a broken line conveying mechanism 1, an inductive fluid releasing mechanism 2 and a straight line conveying mechanism 3. The broken line conveying mechanism 1 is arranged at one end of the straight line conveying mechanism 3, and the inductive fluid releasing mechanism 2 is arranged on the straight line conveying mechanism 3.

[0049] The broken line conveying mechanism 1 comprises an end roller 4, a clamping synchronization assembly 5, a tension transmission assembly 6 and a position sensing plate 7. The straight line conveying mechanism 3 comprises a rack 35, and the end roller 4 is rotatably arranged in the rack 35. The clamping synchronization assembly 5 comprises a sliding clamping block 9, a flange sleeve 10, a synchronization dial 11 and a reset torsional spring 12. The flange sleeve 10 is rotatably arranged on the end roller 4, and a grooved rotating wheel 8 is arranged on the end roller 4. The sliding clamping block 9, which is matched with the grooved rotating wheel 8, is clamped and slidably arranged on the flange sleeve 10. The synchronization dial 11 is rotatably arranged on the flange sleeve 10, and the rotation of the synchronization dial 11 can control the sliding clamping block 9 to expand and contract. The reset torsional spring 12 is arranged between the flange sleeve 10 and the synchronization dial 11.

[0050] Under the elastic force of the reset torsional spring 12, the synchronization dial 11 has a tendency to make the sliding clamping block 9 expand. When the sliding clamping block 9 is subjected to the extrusion force of the transmission belt 13, the sliding clamping block 9 will synchronously contract, so as to realize the combination with the grooved rotating wheel 8.

[0051] The slotted runner 8 is provided with a plurality of annularly distributed engaging recesses 17, the sliding combination block 9 is provided with a plurality of annularly distributed engaging protrusions 20 matched with the engaging recesses 17, and the sliding combination block 9 is further provided with a sliding strip 21, and the flange sleeve 10 is provided with a sliding groove 23.

[0052] The sliding strip 21 is limited in the sliding groove 23, so that the sliding direction of the sliding combination block 9 relative to the flange sleeve 10 is limited, and the movement direction of the sliding combination block 9 is always directed to the axis position of the end roller 4.

[0053] The sliding strip 21 is engaged and slid in the sliding groove 23, and the sliding strip 21 is further provided with a pushing pin 22, the synchronous dial 11 is provided with a plurality of annularly distributed inclined sliding grooves 24, and the pushing pin 22 is slid in the inclined sliding grooves 24.

[0054] The plurality of annularly distributed inclined sliding grooves 24 can control the synchronous sliding of the plurality of sliding combination blocks 9, so that the external contour of the engaging synchronous assembly 5 can be maintained in a circular shape whether the engaging synchronous assembly 5 is expanded or contracted.

[0055] The tension transmission assembly 6 includes a transmission belt 13, a driven wheel 14, a horizontal moving shaft 15 and a Mecanum wheel 16, the horizontal moving shaft 15 is slid in a waist-shaped sliding groove 38 provided in the frame 35, the driven wheel 14 is fixed to the horizontal moving shaft 15, the transmission belt 13 is arranged outside the sliding combination block 9 and the driven wheel 14, the other end of the horizontal moving shaft 15 is rotatably arranged in the frame 35, and the Mecanum wheels 16 are arranged on the horizontal moving shaft 15.

[0056] When the flange seed tray 25 abuts against the position sensing plate 7, the horizontal moving shaft 15 and the Mecanum wheel 16 are rotated, at this time, the flange seed tray 25 is longitudinally moved under the action of the linear transmission mechanism 3; after the flange seed tray 25 abuts against the position sensing plate 7, a group of horizontal moving shafts 15 and Mecanum wheels 16 close to the linear transmission mechanism 3 are connected with the end roller 4 through the engaging synchronous assembly 5 and are rotated, at this time, since the flange seed tray 25 cannot continue to move longitudinally, the flange seed tray 25 is driven to move transversely by the Mecanum wheel 16 until the flange seed tray 25 is separated from the baffle 19.

[0057] The Mecanum wheel 16 can generate a diagonal driving force on the flange seed tray 25 when the Mecanum wheel 16 is rotated, at this time, if the longitudinal movement is limited, the flange seed tray 25 will move transversely.

[0058] The position sensing plate 7 includes a sliding frame 18 and a baffle 19, the sliding frame 18 is slidably arranged on the frame 35, and the baffle 19 is fixed to the sliding frame 18, the sensing type fluid releasing mechanism 2 includes the flange seed tray 25, and the flange seed tray 25 is in sliding contact with the baffle 19.

[0059] The baffle 19 is made of a low-friction material or coating (such as Teflon), which can effectively reduce the sliding resistance between the edged seedling tray 25 and the baffle 19 .

[0060] The inductive fluid release mechanism 2 further includes a feeding assembly 26 and an automatic valve assembly 27 . The feeding assembly 26 is disposed on the frame 35 , and the automatic valve assembly 27 is disposed in the feeding assembly 26 .

[0061] The feeding assembly 26 includes a feeding bracket 28, a feeding pipe 29 and a feeding barrel 30. The feeding bracket 28 is arranged on the frame 35, the feeding pipe 29 is arranged in the feeding bracket 28, the feeding barrel 30 is fixed to the frame 35, and the feeding pipe 29 and the feeding barrel 30 are connected.

[0062] A discharge bevel 34 is provided at the bottom of the feeding barrel 30. The automatic valve assembly 27 includes a plug strip 31, a fork frame 32 and a sensing roller 33. The plug strip 31 is slidably arranged in the discharge bevel 34. The fork frame 32 is fixed to both ends of the plug strip 31. The sensing roller 33 is rotatably arranged at the bottom of the fork frame 32. The sensing roller 33 is in rolling contact with the edge of the edged seedling tray 25.

[0063] Through the cooperation between the flange on the edged seedling tray 25 and the induction roller 33, when the storage area of ​​the edged seedling tray 25 moves to the bottom of the unloading bevel 34, the valve is automatically opened by the rising of the plug strip 31, thereby achieving the technical purpose of automatic feeding at the specified position.

[0064] Since the nutrient soil, water and seeds are all in a fluid state, the main structures of the feeding barrel 30 and the automatic valve assembly 27 are similar, and only the details of the design of the discharge bevel 34 and the plugging rod 31 need to be adaptively matched.

[0065] The linear transmission mechanism 3 further includes a transmission belt 36 and a transmission roller 37 . The transmission roller 37 is rotatably disposed in the frame 35 , and the transmission belt 36 is rollingly disposed on the transmission roller 37 .

[0066] like Figure 11 As shown, the arrows indicate the movement direction and trajectory of the edged seedling tray 25, A, B, and C respectively indicate the workstations for covering the soil, sprinkling water, and sowing, and the dotted boxes indicate the locations of the workstations. A feeding barrel 30 and an automatic valve assembly 27 are provided on each workstation.

[0067] In specific use, first, the user needs to place the strip-rim seedling tray 25 on the conveying belt 36 through an external feeding device, and then transport the strip-rim seedling tray 25 through the movement of the conveying belt 36. When the strip-rim seedling tray 25 is moved to the soil covering station for the first time, the front end of the strip-rim seedling tray 25 will not contact the sensing roller 33, which can avoid the sliding caused by impact on one hand, and can also avoid the embarrassing situation that the soil falls on the edge or outside of the strip-rim seedling tray 25 on the other hand. Then the sensing roller 33 will contact the flange of the strip-rim seedling tray 25 and push the sensing roller 33 to rise through the inclined surface. At this time, the plug strip 31 will rise and unblock the discharge inclined mouth 34, so as to allow the material to fall.

[0068] Since the amount of material required by each station and the fluidity of the material are different, the design height of each group of fork frames 32 is different, so that the opening and gap between the plug strip 31 and the discharge inclined mouth 34 are different when discharging, thereby controlling the amount of feeding.

[0069] After the strip-rim seedling tray 25 passes the soil covering station for the first time, about three-quarters of the nutrient soil has been filled in the strip-rim seedling tray 25. Then when passing the subsequent watering station, the watering device will also be automatically opened to spray the surface soil of the strip-rim seedling tray 25.

[0070] When the strip-rim seedling tray 25 moves to the end of the conveying belt 36, it will be pushed onto the Mecanum wheel 16. Before the strip-rim seedling tray 25 abuts against the position sensing plate 7, the horizontal moving shaft 15 and the Mecanum wheel 16 will rotate with the movement of the strip-rim seedling tray 25. At this time, the strip-rim seedling tray 25 still maintains longitudinal movement under the action of the linear transmission mechanism 3. After the strip-rim seedling tray 25 abuts against the position sensing plate 7, the group of horizontal moving shaft 15 and Mecanum wheel 16 close to the linear transmission mechanism 3 are connected with the end roller 4 through the clamping synchronization assembly 5 and rotate actively. At this time, since the strip-rim seedling tray 25 cannot continue to move longitudinally, the strip-rim seedling tray 25 will move horizontally under the drive of the Mecanum wheel 16.

[0071] After the strip-rim seedling tray 25 abuts against the position sensing plate 7, it will push the sliding frame 18 to slide and slide together with the horizontal moving shaft 15 close to the linear transmission mechanism 3, thereby increasing the shaft spacing between the horizontal moving shaft 15 and the end roller 4. At this time, the transmission belt 13 changes from a relaxed state to a tensioned state, and through its own extrusion, the sliding combination block 9 is synchronously retracted towards the flange sleeve 10. The synchronous dial 11 ensures the synchronization of the movement of each group of sliding combination blocks 9, and the reset torsional spring 12 makes the sliding combination block 9 have a tendency to open in a free state.

[0072] Before the sliding combination block 9 and the slotted runner 8 are combined, the rotation of the slotted runner 8 will not bring the sliding combination block 9 and the flange sleeve 10 to rotate, after the sliding combination block 9 and the slotted runner 8 are combined, due to the cooperation of the engaging convex platform 20 and the engaging concave groove 17, the end roller 4 will also rotate synchronously with the engaging synchronous assembly 5, and then the horizontal moving shaft 15 will be driven to rotate through the transmission belt 13 and the driven wheel 14.

[0073] Before the horizontal movement, the strip-ridge seedling tray 25 will keep pressing the position sensing plate 7 through the driving force of the conveyor belt 36, after the horizontal movement starts, the contact area of the conveyor belt 36 and the strip-ridge seedling tray 25 and the maximum static friction will decrease, at this time, the pressing of the position sensing plate 7 can be kept through the stop of the edge of the frame 35, until leaving the baffle 19, the baffle 19 is made of low-friction material or coating (such as Teflon, etc.), which can effectively reduce the sliding resistance between the strip-ridge seedling tray 25 and the baffle 19.

[0074] During the horizontal movement of the strip-ridge seedling tray 25, uniform sowing will be completed, after the strip-ridge seedling tray 25 leaves the baffle 19, the reset of the synchronous dial 11 will bring the transmission belt 13 and the horizontal moving shaft 15 to reset, and the sliding combination block 9 will also be opened and separated from the slotted runner 8, at this time, the horizontal moving shaft 15 loses power, the strip-ridge seedling tray 25 will be moved under the driving of the conveyor belt 36 on the other side, and secondary watering and soil covering will be carried out when passing through the watering and soil covering stations for the second time, the amount of secondary watering and soil covering is less than that of the first time, and the strip-ridge seedling tray 25 can be taken away by the external feeding device after moving to the end of the conveyor belt 36.

[0075] It is to be noted that the relative terms such as first and second and the like are used herein solely to distinguish one entity or action from another, without necessarily requiring or implying any such actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0076] The above describes the present application and its embodiments, which are not limited, and the drawings only show one of the embodiments of the present application, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired by it, without departing from the purpose of the present application, without creative design, similar structure and embodiments of the technical solution can be designed, which should belong to the protection scope of the present application.
