Description

Technical Field

[0001] The present invention relates to the technical field of seedling separating machines, specifically an automatic peony seedling separating machine. Background Art

[0002] Peony is a special economic crop in Anhui that combines traditional Chinese medicine, health care and ornamental functions. Cortex Moutan is one of the top ten traditional Chinese medicines in Anhui, and peony seed oil is a unique healthy oil in China. With the development of its medical and health care functions, the demand has been steadily increasing, and the market prospect is broad.

[0003] Conventional peony seedling separation usually adopts a single-stage vibration mode. Although its mechanical structure is relatively simple, due to the limited energy distribution of single-stage vibration, the seedling separation task may require multiple repeated operations to complete during the seedling separation process, which takes a long time. And when encountering relatively sticky or difficult-to-vibrate peony bare seedlings, single-stage vibration may not be able to effectively handle them. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an automatic peony seedling separating machine to solve the problem that the seedling separating machine with a single-stage vibration mode is difficult to effectively handle relatively sticky seedlings as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An automatic peony seedling separating machine, including a workbench. A vibration seedling separating mechanism is arranged at the rear side of the workbench. A linear vibration structure, a circular vibration structure and a seedling rolling mechanism are successively arranged on the top surface of the workbench from back to front. A mechanical control mechanism is also arranged on the top surface of the workbench. The vibration seedling separating mechanism, the linear vibration structure and the circular vibration structure jointly form a multi-stage vibration effect on the peony seedlings;

[0006] The vibration seedling separating mechanism includes an elastic frame. A bearing frame is installed at the top of the elastic frame. A feeding frame is arranged above the bearing frame. A vibration motor is arranged at the bottom of the bearing frame. Two intercepting components arranged front and back are detachably installed on the bearing frame. The distance between the bottom of the two intercepting components and the bottom wall of the bearing frame decreases successively from back to front, and the distance is greater than the diameter of a single peony seedling.

[0007] Preferably, the intercepting component includes cross strip plates installed on both sides of the top of the bearing frame. An upper intercepting plate is arranged at the rear side of the cross strip plate. An extension plate is installed on the front side of the upper intercepting plate. An adjusting rod passing through the cross strip plate is rotatably connected to the extension plate. When rotating the adjusting rod, the extension plate is driven to adjust the distance between it and the cross strip plate up and down.

[0008] Preferably, an elastic structure is connected to the back surface of the upper intercepting plate, and a wave plate is connected to the tail end of the elastic structure.

[0009] Preferably, the bottom of the wave plate is at the same height as the bottom of the upper intercepting plate, and it is arranged obliquely. A plurality of grooves arranged vertically are provided on the back of the wave plate, and the cross-sectional shape of the groove is triangular.

[0010] Preferably, the bottom wall of the bearing frame is inclined downward from back to front. A filter screen plate located below the blanking frame is fitted in the bottom wall of the bearing frame, and the front end of the filter screen plate is located between the two intercepting components. A discharge port is installed at the bottom of the bearing frame.

[0011] Preferably, the width of the discharge end of the bearing frame is smaller than the width of the linear vibration structure, and its discharge end is located above the linear vibration structure. The width of the discharge end of the linear vibration structure is smaller than that of the circular vibration structure, and its discharge end is located above the circular vibration structure.

[0012] Preferably, the seedling rolling mechanism includes a guiding frame installed on the top surface of the workbench. A rolling film is sleeved at one end of the guiding frame, a winding structure is installed at the other end of the guiding frame, and a sensor electrically connected to the winding structure is installed in the middle of the guiding frame.

[0013] Preferably, the mechanical control mechanism includes a robotic arm provided on one side of the circular vibration structure. A lifting structure is installed at the free end of the robotic arm, and a grasping structure and a visual recognition structure are installed at the free end of the lifting structure.

[0014] By means of the above technical solutions, the present invention provides a peony automatic seedling separating machine, which has at least the following beneficial effects:

[0015] 1. By combining multi-stage vibrations and combining mechanical control structures and visual recognition related technologies, the present invention realizes the effective dispersion and orderly arrangement of the seedling group.

[0016] 2. By the intercepting components added to the bearing frame, and using the set gap formed between the upper intercepting plate and the bottom wall of the bearing frame, the larger clumped peony bare seedlings are made to be not only affected by the vibration but also by the multiple collision effects with the upper intercepting plate, so that the upper and lower layers of the clumped peony bare seedling pile are dispersed, thereby achieving an expanded dispersion effect of the vibration seedling separating mechanism on the clumped peony bare seedling pile.

[0017] 3. By adding a wave plate and an elastic structure to the back of the upper intercepting plate, when the relatively clumped peony bare seedling pile contacts the back of the wave plate, the upper part of the peony bare seedling pile can be driven to fluctuate back and forth, forming an additional vibration disturbance, thereby accelerating the dispersion efficiency of the peony bare seedling pile in contact with the wave plate.

[0018] 4. The present invention can effectively separate the peony bare seedlings from impurities at the initial vibration dispersion stage. Description of the Drawings

[0028] Embodiment 1

[0029] See also Figures 1-6 , this embodiment proposes an automatic peony seedling separator, which can ensure the dispersion effect of peony seedlings. The peony seedling separator is based on a workbench 1, and a vibration seedling separator 2 is arranged on the rear side thereof to perform preliminary vibration dispersion of peony seedlings. Then, a linear vibration structure 3 and a circular vibration structure 4 are arranged from back to front on the top surface of the workbench 1, and secondary and tertiary vibration dispersions are performed in sequence. Then, the mechanical control mechanism 6 and the seedling rolling mechanism 5 arranged on the top surface of the workbench 1 cooperate to grasp and transfer the finally dispersed peony seedlings to the seedling rolling mechanism 5. Among them, the vibration seedling separator 2 includes an elastic frame 201, a bearing frame 202 is installed on the top of the elastic frame 201, a feeding frame 203 is arranged above the bearing frame 202, and a vibration motor 204 is arranged at the bottom of the bearing frame 202. In actual application, by centrally placing a large number of peony seedlings into the feeding frame 203, the bottom outlet of the feeding frame 203 is relatively small, which meets the requirement that the peony seedlings inside the vibration seedling separator 2 are not easy to fall down when the entire vibration seedling separator 2 is not in operation. Afterwards, the vibration motor 204 is intermittently started according to the set program, and the vibration generated by it controls the bearing frame 202 and the blanking frame 203 above it to follow and produce resonance, so that the peony seedlings in the blanking frame 203 are subjected to vibration and fall into the bearing frame 202. At this time, the fallen peony seedlings are usually in an adhered state. And the bearing frame 202 is supported by its bottom wall being tilted from back to front and downward, and the peony seedlings on its bottom wall are gradually dispersed under the vibration, gradually changing from an adhered state to a stacked state, and moving from back to front, and finally falling into the linear vibration structure 3 through its discharge end, and falling into the circumferential vibration structure 4 through the discharge end of the linear vibration structure 3 for re-vibration and dispersion, so that the state of the peony seedlings on the circumferential vibration structure 4 is finally scattered. Then cooperate with the seedling rolling mechanism 5 to grab a single peony seedling into the seedling rolling mechanism 5 to form a seedling belt roll.

[0030] Specifically, in this embodiment, the peony seedlings that are relatively sticky when initially placed are transformed into a stacked state through the vibrating seedling separation mechanism 2, and then the peony seedlings are migrated and separated through the linear vibration structure 3, and on this basis, the peony seedlings placed from the discharge end of the linear vibration structure 3 to the middle of the circular vibration structure 4 are spread to the surrounding areas in cooperation with the circumferential vibration structure 4. The multi-stage vibration is used in combination to form a multi-stage vibration effect on the peony seedlings, and ultimately ensure the effective dispersion of the peony seedlings.

[0031] More specifically, the mechanical control mechanism 6 includes a robotic arm 601 provided on one side of the circular vibration structure 4. The free end of the robotic arm 601 is equipped with a lifting structure 602, and the free end of the lifting structure 602 is equipped with a grasping structure 603 and a visual recognition structure 604. The robotic arm 601, the lifting structure 602, and the grasping structure 603 are all prior arts, so no detailed description will be given here. In this embodiment, they are intended to grab the scattered bare peony seedlings on the circular vibration structure 4 one by one and transfer them to the seedling rolling mechanism 5. Among them, in cooperation with the visual recognition structure 604, the cameras or visual sensors therein are used to identify the position, size, and shape of the bare peony seedlings. Through image processing technology, the machine can identify and locate each bare peony seedling, thereby improving the accuracy of the grasping structure 603 in grasping the bare peony seedlings.

[0032] Continuing from the above, as Figure 1 shown, the width of the discharge end of the carrying frame 202 is smaller than the width of the linear vibration structure 3, and its discharge end is located above the linear vibration structure 3. The width of the discharge end of the linear vibration structure 3 is smaller than that of the circular vibration structure 4, and its discharge end is located above the circular vibration structure 4. This effectively ensures that when the bare peony seedlings are transferred sequentially between the carrying frame 202, the linear vibration structure 3, and the circular vibration structure 4, there is no situation of spilling outwards.

[0033] Embodiment 2

[0034] Two intercepting components 205 arranged front and back are detachably installed on the carrying frame 202. The distance between the bottoms of the two intercepting components 205 and the bottom wall of the carrying frame 202 decreases sequentially from back to front, and their distances are all greater than the diameter of a single peony seedling. The intercepting component 205 includes cross bar plates 2051 installed on both sides of the top of the carrying frame 202, and an upper intercepting plate 2052 is provided on the rear side of the cross bar plate 2051. Continuing from the above Embodiment 1, during the process of the vibration motor 204 running to cause the bare peony seedlings in the carrying frame 202 to move from back to front, among them, for the adhered or stacked bare peony seedlings, the upper half layer will be intercepted and cooperated by the intercepting component 205 to block the overall flow of the bare peony seedlings. And for the adhered bare peony seedlings, under the continuous action of the vibration force, they will be forced to contact the narrow gap between the bottom of the upper intercepting plate 2052 and the bottom wall of the carrying frame 202. And because the bottom wall of the carrying frame 202 is inclined downward from back to front, it will cause a natural downward sliding force on the bare peony seedlings. The two combined will cause the upper and lower layers of the agglomerated bare peony seedling pile to disperse, thereby achieving the effect of expanding the dispersion of the vibration seedling separating mechanism 2 on the agglomerated bare peony seedling pile. And among them, the slightly larger agglomerated bare peony seedling pile will stay slightly in front of the upper intercepting plate 2052 and further receive the dispersion effect of the vibrating screen, while the qualified-sized bare peony seedlings can smoothly pass through the gap between the upper intercepting plate 2052 and the bottom wall of the carrying frame 202 and be discharged.

[0035] In addition, the presence of the upper interception plate 2052 will impose a certain obstruction to the flow of the bare peony seedlings, prolonging the residence time of the bare peony seedlings at the outlet end of the vibrating screen. This extended residence time allows the bare peony seedlings to be subjected to more vibration force at the outlet end, thereby further dispersing and preventing the bare peony seedlings from exiting too quickly.

[0036] Continuing from the above, an extension plate 2053 is installed on the front surface of the upper interception plate 2052. A regulating rod 2054 that passes through the cross bar plate 2051 is rotatably connected to the extension plate 2053. When the regulating rod 2054 is rotated, it drives the extension plate 2053 to adjust the distance between it and the cross bar plate 2051 up and down. By rotating the regulating rod 2054 upward or downward to adjust the length of its bottom passing through the cross bar plate 2051, the upper interception plate 2052 can be driven to move upward or downward by the extension plate 2053 accordingly, so as to adjust the size of the gap between its bottom and the bottom wall of the bearing frame 202 as needed.

[0037] Embodiment Three

[0038] An elastic structure 2055 is connected to the back surface of the upper interception plate 2052. The tail end of the elastic structure 2055 is connected to a wave plate 2056. The bottom of the wave plate 2056 is at the same height as the bottom of the upper interception plate 2052, and it is arranged in an inclined shape. A number of grooves arranged up and down are provided on the back surface of the wave plate 2056, and the cross-sectional shape of the grooves is triangular. On the basis of Embodiment Two, after the entire vibrating seedling separating mechanism 2 operates, when the relatively cohesive pile of bare peony seedlings behind the upper interception plate 2052 in the bearing frame 202 collides with the back surface of the interception assembly 205, the pile of bare peony seedlings first contacts the wave plate 2056, generating a forward extrusion force on the wave plate 2056. Under the action of the vibration of the entire vibrating seedling separating mechanism 2 and the elasticity and resetting properties of the elastic structure 2055, the wave plate 2056 will drive the upper part of the pile of bare peony seedlings to fluctuate back and forth, forming an additional vibration disturbance, thereby accelerating the dispersion efficiency of the pile of bare peony seedlings in contact with the wave plate 2056.

[0039] Regarding the setting of a number of grooves on the wave plate 2056, it can increase the contact area between the wave plate 2056 and the intercepted bare peony seedlings, improving the interception effect on them.

[0040] Embodiment Four

[0041] Continuing from Embodiment One above, as Figure 1 and Figure 2As shown, a filter plate 2021 located below the blanking frame 203 is fitted into the bottom wall of the bearing frame 202, and the front end of the filter plate 2021 is located between the two intercepting components 205. A discharge port 2022 is installed at the bottom of the bearing frame 202. The bare peony seedlings dropped into the bearing frame 202 through the blanking frame 203 will first enter the range where the filter plate 2021 is located. With the vibration effect generated by the vibration motor 204 on the bearing frame 202, it can cause the bare peony seedlings on the filter plate 2021 to fluctuate up and down. With the characteristics of the filter plate 2021 itself, during the up and down fluctuation of the bare peony seedlings, the impurities shaken off from them will fall along the filter plate 2021 into the discharge port 2022 and then be discharged outwards along the discharge port 2022, thereby achieving the effective separation of the bare peony seedlings and the impurities.

[0042] As Figure 1 and Figure 6 shown, the seedling winding mechanism 5 includes a guiding frame 501 installed on the top surface of the workbench 1. A winding film 502 is sleeved at one end of the guiding frame 501, a winding structure 503 is installed at the other end of the guiding frame 501, and a sensor 504 electrically connected to the winding structure 503 is installed in the middle of the guiding frame 501. The overall seedling winding mechanism 5 is an existing technology, so it will not be described in detail here. Its purpose is to intermittently wind the winding film 502 sleeved at one end of the guiding frame 501 through the winding structure 503. And during this process, in cooperation with the mechanical control mechanism 6, the single bare peony seedlings scattered on the circumferential vibration structure 4 are grabbed and placed on the winding film 502 in the middle of the guiding frame 501. At this time, when the sensor 504 senses the presence of a single bare peony seedling in the front, the winding structure 503 operates in cooperation to realize the winding operation of this single bare peony seedling.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
