Description

Technical Field

[0001] This invention relates to the field of tobacco planting technology, and more specifically, to a multifunctional tobacco planter. Background Technology

[0002] Tobacco seedling cultivation is a crucial step in the tobacco planting process. The quality of seedlings directly determines the survival rate of transplanted tobacco, its growth status, and ultimately the yield and quality of the tobacco leaves. In tobacco seedling cultivation, most small-scale growers still rely on manual methods, manpower-only for tasks such as substrate filling, hole pressing, and sowing. This not only consumes a large amount of manpower and resources, resulting in high labor intensity and extremely low efficiency, but also suffers from strong subjectivity, making it difficult to guarantee the precision of each step. The sowing stage, in particular, has become the core bottleneck affecting seedling quality. Manual sowing relies entirely on the operator's experience to control the number of seeds per hole, making it impossible to accurately achieve the double-seed sowing pattern required for scientific seedling cultivation. This easily leads to problems such as missed sowing, over-sowing, and inconsistent sowing depth.

[0003] To address the drawbacks of manual seedling cultivation, some tobacco sowing equipment has emerged on the market. However, existing equipment generally suffers from problems such as limited functionality, poor process integration, and insufficient sowing precision. The design of sowing components in existing technologies is unreasonable, and there is a lack of effective linkage and coordination between components, making it impossible to stably achieve double-seed sowing. Either the seed quantity cannot be controlled, or seed loss, multiple seeds, or missing seeds are prone to occur, making it difficult to guarantee the scientific seedling standard of two seeds per hole. In addition, existing technologies mostly use adsorption spraying for seed dispensing, which is unreliable during use. Furthermore, existing technologies are inconvenient for replenishing water to the substrate and seeds, resulting in poor functionality. Existing technologies do not have an effective structure for recovering scattered substrate, which cannot be recycled and leads to resource waste.

[0004] Therefore, we have made improvements to this and proposed a multi-functional tobacco planter to solve the problems mentioned above. Summary of the Invention

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Please refer to Figures 1-10This embodiment proposes a multi-functional tobacco planter, including a frame 1. Two first conveyor rollers 2 are rotatably connected to one end of the frame 1, and a first conveyor belt 3 is driven between the two first conveyor rollers 2. A first reduction motor 4 is fixedly connected to the side wall of one end of the frame 1, and the output end of the first reduction motor 4 is fixedly connected to the shaft end of the outer first conveyor roller 2. Two second conveyor rollers 5 are rotatably connected to the other end of the frame 1, and a second conveyor belt 6 is driven between the two second conveyor rollers 5. A second reduction motor 7 is fixedly connected to the rear side wall of the other end of the frame 1, and the output end of the second reduction motor 7 is fixedly connected to the shaft end of the outer second conveyor roller 5. The planter also includes: The substrate addition component 8 is located on the outer side of the first conveyor belt 3 and is used to add substrate to the seedling tray; The pressing component 9 is located on the inner side of the first conveyor belt 3 and is used to press the substrate in the seedling tray into holes. The collection component 10 is located on the lower side between the inner ends of the first conveyor belt 3 and the second conveyor belt 6, and is used to collect the scattered substrate. The seeding component 11 is located on the inner side of the second conveyor belt 6 and is used to add tobacco seeds into the holes. The spray assembly 12 is located on the outer side of the second conveyor belt 6 and is used to add moisture to the tobacco seeds after sowing. The limiting component 13 is located on the upper side of the first conveyor belt 3 and the second conveyor belt 6, and is used to guide and transport the seedling trays.

[0021] The first conveyor belt 3 serves as the transport carrier for the seedling trays during the substrate addition and hole-pressing processes, driving the seedling trays to move continuously and smoothly. The first geared motor 4 serves as the power source for the first conveyor belt 3. During operation, the first geared motor 4 starts, and its output shaft drives the outer first conveyor roller 2 to rotate at a uniform speed. Through the coordinated transmission of the two first conveyor rollers 2, the first conveyor belt 3 is driven to move at a uniform speed along a preset direction, thereby achieving stable transport of the seedling trays. The transport speed can be adjusted by the first geared motor 4 according to the efficiency requirements of the seedling operation to ensure matching with the rhythm of the subsequent substrate addition and hole-pressing processes; the second conveyor... Belt 6 serves as the conveyor for the seedling trays during the sowing and spraying processes. It receives the seedling trays from the first conveyor belt 3 and continues to drive the seedling trays to complete subsequent operations. The second reduction motor 7 serves as the power source for the second conveyor belt 6. When working, the second reduction motor 7 starts, and the output shaft drives the outer second conveyor roller 5 to rotate at a constant speed. Through the coordinated transmission of the two second conveyor rollers 5, the second conveyor belt 6 is driven to move at a constant speed along the preset direction. The conveying speed is synchronized with the first conveyor belt 3, ensuring that the seedling trays smoothly transition from the first conveyor belt 3 to the second conveyor belt 6, and preventing the seedling trays from tilting, falling, or the substrate from scattering.

[0022] like Figures 1-5As shown, in a preferred embodiment, based on the above method, the matrix addition component 8 further includes a bracket 801 disposed on the outer side of the first conveyor belt 3. The bracket 801 is fixedly connected to the frame 1. Two third conveyor rollers 802 are symmetrically and rotatably connected inside the bracket 801. A third conveyor belt 803 is drively connected between the two third conveyor rollers 802. A matrix box 804 is fixedly connected to the upper end face of the bracket 801. A discharge port 805 is opened at the bottom of the inner side wall of the matrix box 804. A baffle 806 is provided on the outer side of the discharge port 805. Two connecting plates 8 are symmetrically and fixedly connected to the upper end face of the baffle 806. 07. Guide openings 808 are provided on both connecting plates 807. Limiting posts 809 are slidably connected in both guide openings 808. The inner end of the limiting post 809 is fixedly connected to the substrate box 804. A connecting plate 8010 is fixedly connected at the center of the upper end face of the baffle 806. A support 8011 is fixedly connected to the side wall of the substrate box 804 near the connecting plate 8010. An electric telescopic rod 8012 is fixedly connected to the support 8011. The driving end of the electric telescopic rod 8012 passes through the support 8011 and is fixedly connected to the end of the connecting plate 8010. A leveling frame 8013 is fixedly connected to the inner side wall of the bracket 801.

[0023] The third conveyor belt 803 can deliver the substrate from the substrate box 804 outwards, allowing the substrate to fall into the seedling tray. The telescopic movement of the electric telescopic rod 8012 drives the connecting plate 8010 to move horizontally, which in turn causes the baffle 806 to slide along the limiting post 809, achieving precise adjustment of the opening of the discharge port 805: when the electric telescopic rod 8012 extends, the baffle 806 moves away from the substrate box 804, increasing the opening of the discharge port 805 and increasing the substrate discharge; when the electric telescopic rod 8012 retracts, the baffle 806 moves closer to... As the substrate box 804 moves, the opening of the outlet 805 decreases, reducing the amount of substrate discharged, thus achieving quantitative addition of substrate to meet the substrate requirements of different sizes of seedling trays. When the seedling tray containing substrate moves with the first conveyor belt 3 to below the leveling frame 8013, the leveling frame 8013 can scrape off the excess substrate in the seedling tray and level the substrate surface at the same time, ensuring that the substrate thickness in the seedling tray is uniform. This lays the foundation for the precise pressing of the hole by the subsequent hole pressing component 9, and avoids inconsistent hole depth due to uneven substrate thickness, which would affect the subsequent sowing quality.

[0024] like Figures 1-5As shown, in a preferred embodiment, based on the above method, a first pulley 8014 is fixedly connected to one end of the rear third conveying roller 802, and a second pulley 8015 is provided on the lower side of the first pulley 8014. The first pulley 8014 is connected to the second pulley 8015 through a first synchronous belt 8016. The second pulley 8015 is fixedly connected to the end of the outer first conveying roller 2 away from the first reduction motor 4. A first housing 8017 is provided on the outer side of the first pulley 8014 and the second pulley 8015, and the first housing 8017 is fixedly connected to the frame 1.

[0025] During operation, the first geared motor 4 drives the first conveyor roller 2 to rotate, which in turn drives the second pulley 8015 to rotate. Through the transmission action of the first synchronous belt 8016, the first pulley 8014 and the rear third conveyor roller 802 are driven to rotate, ultimately driving the third conveyor belt 803 to rotate at a uniform speed. This ensures that the conveying speed of the third conveyor belt 803 is completely synchronized with that of the first conveyor belt 3, preventing the substrate from being added too quickly or too slowly, which could lead to substrate accumulation in the seedling tray or insufficient addition. The first outer shell 8017 protects the first pulley 8014, the second pulley 8015, and the first synchronous belt 8016, preventing external dust and substrate particles from entering the transmission area, preventing wear and jamming of transmission components, ensuring the stable operation of the transmission system, and also preventing operators from accidentally contacting the transmission components, thus improving the safety of equipment operation.

[0026] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the cavitation assembly 9 further includes a mounting frame 901 disposed on the inner side of the first conveyor belt 3. The mounting frame 901 is fixedly connected to the frame 1. A first telescopic cylinder 902 is fixedly connected to the center of the upper end face of the mounting frame 901. The driving end of the first telescopic cylinder 902 passes through the mounting frame 901 and is fixedly connected to a lifting plate 903. A set of cavitation heads 904 are evenly fixedly connected to the lower end face of the lifting plate 903.

[0027] During operation, when the seedling tray filled with uniform substrate moves along the first conveyor belt 3 to directly below the pressing hole assembly 9, the driving end of the first telescopic cylinder 902 extends downward, driving the lifting plate 903 and the pressing hole head 904 to move downward. The pressing hole head 904 inserts into the substrate in the seedling tray, forming uniform holes. After pressing the holes, the driving end of the first telescopic cylinder 902 retracts upward, driving the lifting plate 903 and the pressing hole head 904 to reset and detach from the substrate surface. Then, the first conveyor belt 3 continues to drive the seedling tray forward to enter the next process, realizing continuous pressing hole operation. It is worth noting that detection sensors can be set at the working part of this equipment and used in conjunction with the control system. The control system is existing technology and will not be described in detail here.

[0028] like Figure 1 and Figure 9 As shown, in a preferred embodiment, based on the above method, the collection component 10 further includes a guide seat 1001 disposed on the lower side between the inner ends of the first conveyor belt 3 and the second conveyor belt 6. A base 1002 is provided on the lower side of the guide seat 1001. The base 1002 is fixedly connected to the frame 1. A collection box 1003 is slidably connected inside the base 1002. There is a gap between the inner ends of the first conveyor belt 3 and the second conveyor belt 6.

[0029] During the transition of the seedling tray from the first conveyor belt 3 to the second conveyor belt 6, as well as during the pressing and substrate addition processes, the substrate scattered will fall through the gap between the first conveyor belt 3 and the second conveyor belt 6 into the guide seat 1001. Guided by the guide seat 1001, it will fall into the collection box 1003. When the substrate in the collection box 1003 accumulates to a certain amount, the operator can pull the collection box 1003 out of the base 1002 and pour the collected substrate back into the substrate box 804 to achieve substrate recycling, save seedling costs, and keep the surrounding environment of the equipment clean, avoiding substrate accumulation from affecting the normal operation of the equipment. This gap provides space for the smooth transition of the seedling tray and also provides a channel for the collection component 10 to collect the scattered substrate.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, in a preferred embodiment, based on the above method, the seeding assembly 11 further includes an assembly frame 1101 disposed on the inner side of the second conveyor belt 6. A set of seed tubes 1102 are uniformly fixedly connected to the upper end face of the assembly frame 1101. A drop opening 1103 communicating with the top end of the seed tubes 1102 is opened on the upper end face of the assembly frame 1101. A rotating shaft 1104 is provided on one side of each seed tube 1102. The rotating shafts 1104 are rotatably connected to the top wall of the assembly frame 1101. A turntable 1105 is fixedly connected to the top of the shaft 1104. A set of seed storage holes 1106 are evenly distributed on the turntable 1105. A driven bevel gear 1107 is fixedly connected to the bottom of the shaft 1104. Two mounting ears 1108 are symmetrically and fixedly connected to the lower end face of the top plate of the mounting frame 1101. A rotating rod 1109 is rotatably connected between the two mounting ears 1108. A set of driving bevel gears 1110, which mesh with the driven bevel gear 1107, are evenly and fixedly connected to the rotating rod 1109. One end of the assembly frame 1101 is fixedly connected to a third pulley 1111. A fourth pulley 1112 is located below the third pulley 1111. The third pulley 1111 is connected to the fourth pulley 1112 via a second synchronous belt 1113. The fourth pulley 1112 is fixedly connected to the end of the inner second conveying roller 5 near the second reduction motor 7. A second outer casing 1114 is located outside the third pulley 1111 and the fourth pulley 1112. The second outer casing 1114 is fixedly connected to the frame 1. A type of assembly frame 1101 is located on its upper side. Seed storage box 1115 has two fixed rods 1116 symmetrically and fixedly connected on it. The bottom ends of the two fixed rods 1116 are fixedly connected to the upper end face of the assembly frame 1101 respectively. A set of seed lowering covers 1117 connected to the lower end face of the seed storage box 1115 are evenly fixedly connected. The bottom end of the seed lowering cover 1117 is fixedly connected to a guide tube 1118 that cooperates with the turntable 1105 and the seed storage hole 1106. The bottom end of the guide tube 1118 is in contact with the upper end face of the turntable 1105.

[0031] During operation, the second reduction motor 7 drives the second conveyor roller 5 to rotate, which in turn drives the fourth pulley 1112 to rotate. Through the transmission action of the second synchronous belt 1113, the third pulley 1111 and the rotating rod 1109 rotate, ultimately driving the driving bevel gear 1110, the driven bevel gear 1107, the rotating shaft 1104, and the turntable 1105 to rotate synchronously. The rotation speed of the turntable 1105 is precisely matched with the conveying speed of the second conveyor belt 6, ensuring that when each seed storage hole 1106 rotates to the drop outlet 1103, the seedling tray hole below is exactly aligned with the seeding tube 1102, achieving precise sowing. The seeding cover 1117 is funnel-shaped, and the guide tube 1 118 facilitates the smooth falling of seeds into the seed storage holes 1106. Each seed storage hole 1106 can ensure that exactly two seeds are received. During operation, the seeds in the seed storage box 1115 are guided by the seed release cover 1117 and fall into the seed storage holes 1106 of the turntable 1105 through the guide tube 1118. Each seed storage hole 1106 accurately receives two seeds. When the turntable 1105 rotates to above the drop outlet 1103, the two seeds in the seed storage holes 1106 fall into the seed release tube 1102 under the action of gravity, and then fall accurately into the holes of the seedling tray from the seed release tube 1102, completing the double seed sowing. like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, in a preferred embodiment, based on the above method, the upper end face of the assembly frame 1101 is further provided with a set of sliding grooves 1119 that communicate with the drop opening 1103. A stop frame 1120 is slidably connected in the sliding grooves 1119. Each of the multiple support arms of the stop frame 1120 has a limit port 1121. A limit head 1122 is slidably connected in the limit port 1121. The limit head 1122 is fixedly connected to the assembly frame 1101 by an internal hex bolt. A bearing seat 1123 is fixedly connected to the upper end face of the assembly frame 1101. A second telescopic cylinder 1124 is fixedly connected to the bearing seat 1123. The driving end of the second telescopic cylinder 1124 is fixedly connected to the outer end of the stop frame 1120.

[0032] During operation, the extension and retraction of the second telescopic cylinder 1124 causes the baffle 1120 to slide outward along the slide groove 1119, thereby removing the obstruction of the drop opening 1103 and facilitating sowing. When not sowing, the baffle 1120 blocks the drop opening 1103 to prevent the seeds from falling.

[0033] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, the spray assembly 12 further includes a gantry frame 1201 disposed on the outer side of the second conveyor belt 6. The gantry frame 1201 is fixedly connected to the frame 1. Two guide sleeves 1202 are symmetrically and fixedly connected to the inner top wall of the gantry frame 1201. A spray pipe 1203 is fixedly connected between the two guide sleeves 1202. Atomizing nozzles 1204 are uniformly and fixedly connected to the output end of the spray pipe 1203. A fixing plate 1205 is fixedly connected to the bottom of the frame 1. A water storage tank 1206 is fixedly connected to the upper end face of the fixing plate 1205. A conveying pump 1207 is fixedly connected to the upper end face of the fixing plate 1205. The input end of the conveying pump 1207 is connected to and fixedly connected to the water storage tank 1206 through a first connecting pipe 1208. A second connecting pipe 1209 is fixedly connected to the output end of the conveying pump 1207. The top end of the second connecting pipe 1209 is fixedly connected to the input end of the spray pipe 1203.

[0034] When the delivery pump 1207 is started, it draws clean water from the water storage tank 1206 through the first connecting pipe 1208. After being pressurized by the delivery pump 1207, the water is delivered to the spray pipe 1203 through the second connecting pipe 1209. The clean water is evenly distributed in the spray pipe 1203, and then atomized by the atomizing nozzle 1204 and evenly sprayed onto the seedling trays moving on the second conveyor belt 6 to replenish the water for the seeds after sowing. The amount of water sprayed can be controlled by adjusting the output power of the delivery pump 1207 to ensure that the water content meets the requirements for seed germination and to avoid excessive water causing seed rot or insufficient water affecting seed germination.

[0035] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a strip-shaped opening is further provided on the outer wall of the water storage tank 1206, and a transparent plate is fixedly connected inside the strip-shaped opening. A water filling head is provided on the outer wall of the water storage tank 1206.

[0036] The transparent panel allows for easy viewing of the remaining water level in the water storage tank 1206, facilitating timely refilling of the tank.

[0037] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, two guide plates 1301 are symmetrically provided on the first conveyor belt 3 and the second conveyor belt 6. A set of connecting blocks 1302 are fixedly connected to the outer side wall of each of the two guide plates 1301. A locking seat 1303 is slidably connected to each connecting block 1302. The locking seat 1303 is fixedly connected to the frame 1. A locking bolt 1304 for pressing and locking the connecting block 1302 is threadedly connected at the center of the upper end face of the locking seat 1303.

[0038] When it is necessary to adapt to the width of the seedling tray, loosen the locking bolt 1304, push the connecting block 1302 to drive the guide plate 1301 to slide, adjust to the appropriate distance, and then tighten the locking bolt 1304 again. The operation is convenient and improves the versatility of the device.

[0039] Specifically, when using this multi-functional tobacco seeder: First, loosen the locking bolt 1304, push the connecting block 1302 to drive the guide plate 1301 to slide, adjust to a suitable distance, and then tighten the locking bolt 1304 again. Start the first reduction motor 4 and the second reduction motor 7. Place the empty seedling tray at the input end of the first conveyor belt 3. The first reduction motor 4 drives the first conveyor roller 2 to rotate, driving the first conveyor belt 3 to move at a uniform speed. The seedling tray moves with the first conveyor belt 3 towards the substrate adding component 8. At the same time, the second reduction motor 7 drives the second conveyor roller 5 to rotate, driving the second conveyor belt 6 to move at a uniform speed, keeping pace with the first conveyor belt 3. The electric telescopic rod 8012 controls the baffle 806 to move upward, and the substrate in the substrate box 804... The substrate falls onto the third conveyor belt 803 through the outlet 805. Driven by the first pulley 8014, the second pulley 8015, and the first synchronous belt 8016, the third conveyor belt 803 rotates synchronously with the first conveyor belt 3, evenly conveying the substrate into the seedling tray. The seedling tray continues to move, and the substrate is leveled by the leveling frame 8013 to ensure uniform substrate thickness. The seedling tray containing the uniform substrate moves to below the pressing assembly 9, and the first telescopic cylinder 902 drives the pressing head 904 downwards, inserting it into the substrate to form holes of uniform depth. The pressing head 904 then resets, and the seedling tray continues to move forward. During the transition from the seedling tray to the second conveyor belt 6, the scattered substrate falls into the guide seat 10 through the gap between the first conveyor belt 3 and the second conveyor belt 6. 01. Guided by guide seat 1001, the seeds enter collection box 1003 and are recycled after a certain amount is collected. The seedling tray transitions to the second conveyor belt 6 and moves towards the sowing component 11. Simultaneously, the second conveyor roller 5 drives the rotating rod 1109 to rotate via the third pulley 1111, the fourth pulley 1112, and the second synchronous belt 1113. This, in turn, drives the rotating shaft 1104 and the turntable 1105 to rotate synchronously via the driving bevel gear 1110 and the driven bevel gear 1107. At this time, the seeds in the seed storage box 1115 fall precisely into the seed storage hole 1106 of the turntable 1105 through the seed cover 1117 and the guide tube 1118. Due to the precise design of the seed storage hole 1106, only two seeds can be stably stored at a time, and any excess seeds will be blocked. The system uses a barrier to strictly ensure the sowing standard of two seeds per hole. Subsequently, the seed storage hole 1106 rotates with the turntable 1105 to the drop outlet 1103. Under the action of gravity, two seeds fall precisely into the holes of the seedling tray through the seeding tube 1102, achieving double-seed precision sowing. This takes into account both seed germination rate and seedling growth space. During sowing, the extension and retraction movement of the second telescopic cylinder 1124 drives the barrier 1120 to slide outward along the slide groove 1119, thereby removing the obstruction to the drop outlet 1103 and facilitating sowing. After sowing, the seedling tray continues to move to the bottom of the spray assembly 12. The delivery pump 1207 pressurizes the clean water in the water storage tank 1206 and sprays it through the spray pipe 1203 and the atomizing nozzle 1204 to replenish the seeds with water and ensure seed germination.After being sprayed, the seedling trays move to the output end via the second conveyor belt 6. Operators then remove the trays for further cultivation, thus automating the entire seedling and sowing process.
