Description

Technical Field

[0001] This application relates to the field of agricultural seedling equipment technology, and more specifically to a soil-filled seedling production line that can be used for both seedling trays and mother seedling pots. Background Technology

[0002] With the development of agricultural economy, agricultural seedling cultivation has become a major industry for social progress. In the existing sowing production line, manual soil filling and seedling planting are mostly used. In addition, planting containers include plug trays and mother seedling pots. A plug tray is a tray with multiple small-capacity substrate cavities arranged in an array, while a mother seedling pot is a pot with a large-capacity substrate cavity.

[0003] Patent document (CN204069914U) discloses a seedling tray filling machine, including a belt conveyor mechanism, a chain scraper lifting mechanism, a substrate pouring hopper, a substrate box, and a substrate conveying mechanism located inside the substrate box. The belt conveyor mechanism transports seedling trays, the substrate box is filled with substrate, and the substrate conveying mechanism sends the substrate to one side of the chain scraper lifting mechanism. The chain scraper lifting mechanism uses chain teeth to scoop up and store the delivered substrate. When the chain teeth move to the top and flip, the substrate placed on the chain teeth falls into the substrate pouring hopper under gravity, and then falls into the seedling tray on the belt conveyor mechanism. However, the above-mentioned seedling tray filling machine only completes the placement of substrate into the seedling tray, without addressing how to facilitate subsequent seedling planting; furthermore, it is not suitable for filling and planting seedlings in mother seedling pots.

[0004] Therefore, there is a need for a soil-filled seedling production line that can be used for both seedling trays and mother seedling pots and is highly efficient in sowing. Summary of the Invention

[0005] The main objective of this application is to provide a soil-filled seedling planting production line that can be used for both seedling trays and mother seedling pots.

[0034] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0035] An illustrative soil-filled seedling planting assembly line that combines seedling trays and mother seedling pots, for reference. Figures 1 to 10 According to a preferred embodiment of the present invention, a soil-filling seedling production line that can be used for both seedling trays and mother seedling pots includes a base 10, two feeding devices 20, and a second transverse conveyor belt 30.

[0036] Specifically, such as Figures 2 to 4 As shown, the two feeding devices 20 are arranged at intervals. Each feeding device 20 includes a substrate hopper 201, a first longitudinal conveyor belt 202, a substrate lifting mechanism 203, a discharge hopper 204, and a first transverse conveyor belt 205. The first longitudinal conveyor belt 202 is provided on the bottom surface of the substrate hopper 201. The first longitudinal conveyor belt 202 is arranged along the width direction of the soil filling and seedling production line that can be used for both seedling trays and mother seedling pots. The substrate lifting mechanism 203 is arranged at an inclination. The lowest point of the substrate lifting mechanism 203 is close to the end of the first longitudinal conveyor belt 202 away from the substrate hopper 201, and the discharge hopper 204 is provided on one side of the top of the substrate lifting mechanism 203. The first transverse conveyor belt 205 is located below the discharge hopper 204. In addition, a baffle is detachably installed at one end of the first transverse conveyor belt.

[0037] In addition, the second transverse conveyor belt 30 is movably mounted on the machine base 10 along the length of the dual-purpose seedling planting line for both seedling trays and mother seedling pots. The second transverse conveyor belt 30 is located between the first transverse conveyor belt 205 and the first longitudinal conveyor belt 202 in the height direction. Seedling trays or mother seedling pots are placed on one end of the second transverse conveyor belt 30 near the feeding device 20.

[0038] It should be noted that a large quantity of soil substrate is poured into the substrate hopper 201. The first longitudinal conveyor belt 202 then transports the soil substrate to the substrate lifting mechanism 203, which lifts it upwards. After reaching its highest position, the soil substrate falls into the discharge hopper 204 and is then moved onto the second transverse conveyor belt 30 by the movement of the first transverse conveyor belt 205. It is important to emphasize that the seedling tray has several rectangular arrayed substrate receiving slots, and the seedling pot has a large-capacity substrate receiving slot. The second transverse conveyor belt 30 transports the seedling tray below the first transverse conveyor belt 205. When the soil substrate falls from the transverse conveyor belt, the seedling tray is positioned at one end of the first transverse conveyor belt 205 and receives the soil substrate, which then falls onto the seedling tray or the seedling pot. It should be noted that the width of the seedling tray is greater than the width of the mother seedling pot. This is why the baffle is removed and installed at one end of the first transverse conveyor belt. When filling the mother seedling pot with soil and planting seedlings, the two baffles are placed at both ends of one side of the first transverse conveyor belt, so that the substrate can only pass between the two baffles and fall into the mother seedling pot with the smaller width. When filling the seedling tray with soil and planting seedlings, the two baffles are removed.

[0039] It should be noted that when the soil substrate falls onto the seedling tray, it may fall onto the surface of the tray in addition to the soil substrate in the substrate receiving groove. Furthermore, the soil substrate is not perfectly flat and compacted after falling into the substrate receiving groove; it should be added that the soil substrate falling into the substrate receiving groove is used for planting seedlings.

[0040] Therefore, in this application, as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the dual-purpose seedling tray and mother seedling pot filling and planting production line also includes a scraping and pressing module and a punching device 303, a seedling placement platform 304 and a spraying device 305 arranged sequentially above the second transverse conveyor belt 30. Each scraping and pressing module includes a leveling mechanism 301 and a compaction mechanism 302. The leveling mechanism 301 is raised and lowered in the height direction of the machine base 10, and the compaction mechanism 302 is detachably installed on the machine base 10. Each feeding device 20 has a scraping and pressing module on one side.

[0041] It should be noted that by setting the leveling mechanism 301 on one side of the feeding device 20, when the seedling tray or the mother seedling pot passes through the leveling mechanism 301, the soil substrate overflowing from the opening of the substrate receiving trough can be scraped off by the leveling mechanism 301. Subsequently, the seedling tray continues to move with the second transverse conveyor belt 30 to the compaction mechanism 302, and the soil substrate in each substrate receiving trough is compacted by the compaction mechanism 302. In addition, since the height of the mother seedling pot is relatively high, when the mother seedling pot is placed on the second transverse conveyor belt 30... When necessary, the compaction mechanism 302 needs to be removed, and the height of the leveling mechanism 301 needs to be increased. Additionally, the purpose of setting up two feeding devices 20 is that after the substrate in the first feeding device 20 is leveled, compacted, or simply leveled by the scraping module, the substrate on the plug tray or seedling pot is replenished by the other feeding device 20. Then, it undergoes another leveling, compacting, or simple leveling process by the leveling module. That is, when placing the plug tray, it needs to be leveled and compacted; when placing the seedling pot, it only needs to be leveled. Afterward, the plug tray or seedling pot continues to follow the second horizontal... The conveyor belt 30 moves to below the punching device 303. It should be noted that if the seedling pot moves to below the punching device 303, the punching device 303 punches holes in the soil substrate in the substrate receiving trough. If the seedling tray moves to below the punching device, the punching device 303 does not operate; that is, the seedling tray simply passes through the punching device 303. Subsequently, the seedling tray or the seedling pot continues to move with the second transverse conveyor belt 30 to one side of the seedling placement platform 304. At this time, the seedling is placed in the platform manually or by a robotic arm. After the seedling is placed into the hole made by the punching device 303, the soil substrate near the hole is filled into the hole (the substrate receiving groove on the seedling tray is shallow, allowing the seedling to be inserted directly). Then, the seedling tray or the mother seedling pot continues to move along the second transverse conveyor belt 30 to the spraying device 305. It should be noted that if the mother seedling pot moves below the spraying device 305, the seedling is pre-wetted by the spraying device 305; if the seedling tray moves below the spraying device 305, the spraying device 305 does not operate. It is evident that, compared to the prior art, this application covers the entire process of filling soil and planting seedlings, offering the advantages of dual-use seedling trays and mother seedling pots, and efficient sowing.

[0042] Furthermore, the matrix lifting mechanism 203 can be specifically implemented as follows: Figure 7As shown, the substrate lifting mechanism 203 includes a sleeve 2031 and a screw feeder 2032. The sleeve 2031 is sleeved on the outside of the screw feeder 2032. The bottom of the screw feeder 2032 is close to the first longitudinal conveyor belt 202. The screw feeder 2032 includes a rotary motor and a shaft. The outer wall of the shaft has helical blades. The rotating shaft of the rotary motor is connected to the shaft. When the rotating shaft of the rotary motor rotates circumferentially, it drives the shaft to rotate circumferentially. When the soil substrate moves to the helical blades at the bottom of the shaft, by rotating the shaft circumferentially, the soil substrate is gradually moved to the discharge port at the top of the screw feeder 2032 and falls into the discharge hopper 204. Alternatively, the substrate lifting mechanism 203 can also be a vertical conveyor belt as disclosed in patent document (CN204069914U). The vertical conveyor belt has spaced soil-shoveling structures, and the soil-shoveling structures are ratchet teeth.

[0043] Furthermore, in order to level the soil matrix outside the opening of the matrix receiving trench, such as... Figure 8 and Figure 9 The scraping mechanism 301 includes a first base 3011, a rotary drive device 3012, and a rotating roller 3013. The rotating roller 3013 is rotatably mounted on the first base 3011, and the rotary drive device 3012 is fixedly mounted on the first base 3011. The rotating shaft of the rotary drive device 3012 is poweredly connected to the rotating roller 3013 through gear transmission.

[0044] It should be noted that when the rotating shaft of the rotary drive device 3012 rotates circumferentially, the rotating roller 3013 also rotates circumferentially, and the lowest point of the rotating roller 3013 is flush with the opening of the substrate receiving groove (which is also the highest point of the seedling tray or the mother seedling pot). When the rotating roller 3013 rolls over the soil substrate at the opening of the substrate receiving groove, it flattens the "peak" of the soil substrate extending from the opening of the substrate receiving groove.

[0045] Furthermore, to improve the leveling effect, the leveling mechanism 301 also includes two cross-arranged scraper plates 3014. Both scraper plates 3014 are fixedly installed on the side of the rotating roller 3013 near the feeding device 20, and the lowest point of the two scraper plates 3014 is higher than the lowest point of the rotating roller 3013.

[0046] It should be noted that in this application, the included angle between the two scraping plates 3014 is an obtuse angle. Before the rotating roller 3013 comes into contact with the soil substrate at the opening of the substrate receiving groove, the soil substrate at a higher position is scraped off by the scraping plate 3014. That is, in this application, the leveling mechanism 301 includes two leveling structures: the scraping plate 3014 and the rotating roller 3013.

[0047] Furthermore, to enable the leveling mechanism 301 to be raised and lowered in the height direction, as follows: Figure 8 and Figure 9 The leveling mechanism 301 is vertically mounted on the machine base 10. Specifically, the leveling mechanism 301 further includes a guide rod, a lead screw 3015, and a turntable 3016. The lead screw 3015 and the guide rod are both vertically arranged. The lead screw 3015 is rotatably mounted on the machine base 10. The guide rod passes through the first seat body 3011. The lead screw 3015 is connected to the first seat body 3011 via a slider. The guide rod is fixedly mounted on the machine base 10. The turntable 3016 is fixedly connected to the top of the lead screw 3015, and the fixed connection method includes, but is not limited to, welding. It should be noted that when the height of the rotating roller 3013 needs to be adjusted, the turntable 3016 can be held and rotated, causing the first seat body 3011 to move upward or downward under the principle of the lead screw 3015 slider.

[0048] Furthermore, after the soil substrate placed at the opening of the substrate receiving groove is leveled, in order to achieve compaction of the soil substrate, such as... Figure 5 and Figure 8 As shown, the compaction mechanism 302 includes a second base 3021 and a roller 3022. The roller 3022 is rotatably mounted on the second base 3021. The side wall of the roller 3022 has a plurality of protrusions 3023. The second base is detachably connected to the machine base.

[0049] It should be noted that the number of protruding pillars 3023 arranged along the central axis of the roller 3022 is the same as the number of substrate receiving grooves in the width direction of the seedling tray. When the seedling tray is placed on the second transverse conveyor belt 30, the protruding pillars 3023 and the substrate receiving grooves are directly opposite each other in the width direction. When the seedling tray is driven by the second transverse conveyor belt 30 and comes into contact with the protruding pillars 3023 on the roller 3022, the protruding pillars 3023 are subjected to a counterclockwise force, causing the roller 3022 to rotate circumferentially. When the protruding pillars 3023 move to the lowest point of the roller 3022, that is, when the protruding pillars 3023 are vertically arranged and close to the second transverse conveyor belt 30, the protruding pillars 3023 compact the soil in the substrate receiving groove. When placing the seedling pot, the compaction mechanism 302 is removed.

[0050] Furthermore, since the protruding post 3023 is in full contact with the soil matrix in the matrix receiving groove, the soil matrix may adhere to the protruding post 3023. Therefore, as... Figure 8 As shown, the compaction mechanism 302 also includes a cleaning component 3024, which is detachably mounted on the machine base 10. The cleaning component 3024 is located above one side of the roller 3022. When the roller 3022 rotates, the cleaning component 3024 removes the soil from the protrusion 3023.

[0051] It should be noted that the cleaning component 3024 can be implemented as a soft brush fixed to one side of the roller 3022. When the roller 3022 rotates circumferentially, the soft brush contacts the protrusion 3023 and scrapes off the dirt on the protrusion 3023. The cleaning component 3024 can also be implemented as an air gun. When the roller 3022 rotates circumferentially, the airflow blows onto the protrusion 3023 to remove the dirt on the protrusion 3023.

[0052] Furthermore, the punching device 303 includes a lifting drive device and several inserts. The lifting drive device is fixedly installed on the base 10. The push rod of the lifting drive device is fixedly connected to the inserts. When the push rod of the lifting drive device moves, the inserts move closer to or further away from the second transverse conveyor belt 30 in the height direction.

[0053] It should be noted that, in order to enable the lifting drive device to simultaneously move multiple inserts up and down, each insert can be connected by a connecting rod, and the connecting rod can be fixedly connected to the push rod of the lifting drive device. The fixed connection method includes, but is not limited to, bolt connection. The push rod of the lifting drive device moves downward and drills holes in the compacted soil base, providing favorable conditions for planting seedlings. It should be added that the drilling device 303 only works when the mother seedling pot is placed.

[0054] Furthermore, to facilitate the retrieval of seedlings placed in trays on the seedling placement platform 304, the seedling placement platform 304 is located on one side of the second transverse conveyor belt 30, as shown in the reference. Figure 10 Each of the seedling placement platforms 304 has an inclined L-shaped platform surface.

[0055] It should be noted that after holes are punched in the soil substrate placed in the substrate receiving trough, the seedling tray or the mother seedling pot moves along the second transverse conveyor belt 30 to one side of the seedling placement platform 304. The operator or robot can grab the seedling placed on the seedling placement platform 304 and put its roots into the soil substrate in the substrate receiving trough. If there are holes in the soil substrate, the seedling is put into the holes. Then, a pushing force is applied to the soil near the holes to fill the holes and cover the roots of the seedling.

[0056] In addition, the spraying device 305 includes several nozzles connected to an external water source. These nozzles can be atomizing nozzles, and the spraying device 305 is used to pre-wet the seedling trays after planting. Since the spraying device 305 is a mature technology, its specific structure and model will not be described in detail here. The spraying device 305 includes, but is not limited to, the device for spraying seedlings disclosed in patent document (CN212464260U). The spraying device 305 only operates when the mother seedling tray is placed in the tray.

[0057] In summary, the soil-filled seedling production line that combines seedling trays and mother seedling pots, as described in the embodiments of this application, has been clarified, providing advantages such as efficient sowing.

[0058] It is worth mentioning that, in this embodiment, the dual-purpose seedling tray and mother seedling pot soil-filling planting line has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the dual-purpose seedling tray and mother seedling pot soil-filling planting line provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0059] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
