Description

Technical Field

[0001] The invention relates to the field of seedling transplanting, and in particular to a seedling transplanting device and method for agricultural planting. Background Art

[0002] At present, agricultural planting has all achieved mechanized agricultural production, and seedling transplanting devices for agricultural planting will be used. The seedling transplanting device for agricultural planting is an agricultural machinery equipment used to transfer crop seedlings from nurseries or seedling containers to planting sites. It can greatly improve transplanting efficiency, reduce labor intensity and improve planting quality.

[0003] In traditional agricultural planting, seedling transplanting is mostly done by manual drilling or with the help of other equipment, and then transplanting through transplanting machinery. During the planting process, it is not easy to ensure that the size of the holes is consistent. At the same time, when faced with the need to deeply plant agricultural seedlings, traditional devices usually do not have a special depth adjustment function. If the planting depth needs to be adjusted, it is often necessary to disassemble and replace the components. At the same time, the traditional simple seedling throwing structure lacks effective control over the seedling posture, and the seedlings often fall to one side of the pit when they fall from the transplanting machinery into the planting pit.

[0004] The existing transplanting devices usually carry out fertilization and pit digging operations separately, requiring operators to operate different equipment multiple times, and lack a mechanism to control the amount of fertilizer. Most of them rely on adjusting the opening size of the fertilization equipment or need to disassemble, replace or re-debug multiple parts to control the amount of fertilizer, resulting in obvious differences in the amount of fertilizer applied each time, making it difficult to meet the precise fertilizer requirements of different crops and different growth stages. At the same time, after the fertilizer is spread out from the storage device, there is a lack of fertilizer dispersion and guidance mechanism, and it falls directly into the planting pit in a block or concentrated form, making the fertilizer distribution in the pit uneven. If the fertilizer concentration in some areas is too high, it is easy to burn the roots of the seedlings, resulting in stunted growth or even death of the seedlings. When there is insufficient fertilizer in some areas, the seedlings cannot obtain enough nutrients, grow slowly, and develop poorly. This uneven fertilizer distribution will cause uneven growth of seedlings planted in the same batch, bring great difficulties to subsequent field management, and ultimately affect the overall yield and quality of crops.

[0005] Therefore, it is necessary to provide a seedling transplanting device and method for agricultural planting to solve the above problems. Summary of the invention

[0013] Preferably, the worm is rotatably connected to the inside of the first positioning block.

[0014] An operating method of a seedling transplanting device for agricultural planting, the seedling transplanting device method comprising the following steps: Step 1: Prepare a punching head that matches the size of the target hole and install the appropriate punching head at the bottom of the limit head; Step 2: Select a suitable size of rotary chuck for replacement according to the required pit depth; Step 3: Start the servo motor. During the movement of the transplanter, the limit head and the punching head automatically dig holes of the same size according to the rotating chuck during the rotation and lifting process. Step 4: When the seedling dropping group drops the agricultural seedlings, check whether the arc-shaped straightening slide is in a vertical state to ensure that the agricultural seedlings fall at a vertical angle; Step 5: When the fertilizer inside the storage barrel is exhausted, put the fertilizer into the storage barrel to ensure that there is enough fertilizer. After the punching head punches a hole, the fertilizer discharge plate is triggered to release the fertilizer at the same time; Step 6: Use the L-shaped adjustment rod to adjust the height of the arc-shaped clamping ring and the lower plate to control the amount of fertilizer added.

[0016] Preferably, before each seedling planting in step 4, it is also necessary to check whether the surface of the arc-shaped straightening slide plate is smooth and whether there is any debris attached to avoid scratching the seedlings.

[0017] The present invention provides a seedling transplanting device and method for agricultural planting. Compared with the prior art, the present invention has the following beneficial effects: Through the setting of the driving component and the depth adjustment component, compared with the traditional seedling transplanting device for agricultural planting, the traditional device requires manual cooperation of multiple tedious steps, such as manually turning or pushing a complex mechanical structure to achieve operations such as punching holes, while this structure only requires the staff to start the servo motor, and the subsequent power transmission and execution actions can be automatically and continuously completed. At the same time, the consistency of the size of each hole can be ensured, which improves the overall efficiency of agricultural seedling transplanting, and does not require excessive manual intervention, reducing the difficulty of operation for operators; When facing the need for deep planting of agricultural seedlings, you only need to pull out the pin rods at both ends of the worm gear and replace them with a larger diameter rotating chuck. By changing the diameter of the rotating chuck, the up and down movement range of the connecting rod can be changed. Then, the up and down movement range of the limit head and the punching head can be accurately increased through the Y-shaped lever and the fitting block, so as to achieve flexible and accurate adjustment of the pit depth and meet the diverse needs of different agricultural seedlings for planting depth. Through the setting of the fertilization component and the quantity control component, and through the linkage of the synchronous wheel 1, the synchronous wheel rod, the upper plate and other components, the frequency matching of fertilization and digging is achieved. When the limit head and the punching head make holes, the fertilizer can be accurately sprinkled in. And through the precise control of the lower plate by the L-shaped adjustment rod, the amount of fertilizer put in each time can be accurately adjusted according to the needs of different crops and soil fertility. In the seedling throwing stage, the traditional seedling transplanting device for agricultural planting mostly relies on a simple seedling throwing structure, which makes it difficult to ensure that the seedlings can fall vertically into the pit after being raised. The setting of the arc-shaped straightening slide can guide the seedlings to slide down along a specific trajectory, ensuring that they fall vertically into the pit. In addition, during the fertilizer spreading process, the fertilizer is first gradually dispersed through the dividing blocks, and then evenly spread into the pits along the spreading blocks according to a fixed path, which helps the roots of the seedlings to absorb nutrients evenly.

[0024] A driving assembly is arranged above the transplanter 11, and the driving assembly includes two servo motors 23. The two servo motors 23 are installed on the top of the inner cavity of the dustproof shell 22. A synchronous wheel 24 is fixedly connected to the output shaft of each servo motor 23.

The bottom of the limiting head 28 is threadedly connected with a punching head 210.

[0026] like Figures 10 to 15As shown, a fertilization assembly is arranged inside the dustproof shell 22, and the fertilization assembly includes two upper plates 41, and the two upper plates 41 are rotatably connected to the bottom of the inner cavity of the dustproof shell 22, and a synchronous wheel rod 42 is fixedly connected to the top of the upper plate 41, and the synchronous wheel rod 42 is composed of a synchronous wheel and a straight rod fixedly connected to its end face, and a synchronous belt 411 is sleeved between the synchronous wheel rod 42 and the synchronous wheel 24, and two storage barrels 410 are fixedly connected to the top of the dustproof shell 22, and the bottoms of the two storage barrels 410 are fixedly connected to the positioning drop-off port 43, and the tops of the two upper plates 41 are symmetrically provided with discharge ports 44, and the middle part of the upper plate 41 is slidably connected to the lower plate 45, and the top of the lower plate 45 is symmetrically provided with columnar grooves 46, and the bottom of the upper surface of the lower plate 45 is symmetrically rotatably connected to a fertilizer discharge plate 47, and the top of the fertilizer discharge plate 47 is fixedly connected to a material dividing block 48, and the bottom of the dustproof shell 22 is symmetrically fixedly connected to a spreading block 49.

[0027] A quantity control component is provided at the bottom of the upper plate 41, and the quantity control component includes two arc-shaped snap rings 51, and the two arc-shaped snap rings 51 are both clamped on the bottom of the lower plate 45. An arc-shaped groove 52 is provided on the top of the arc-shaped snap ring 51, which is used to trigger the fertilizer discharge plate 47 to rotate and discharge fertilizer. The bottom of the arc-shaped snap ring 51 is rotatably connected to an L-shaped adjusting rod 53, and the bottom of the dustproof shell 22 is symmetrically fixedly connected to a gear block 54, and the L-shaped adjusting rod 53 is rotatably connected to the inside of the gear block 54, and the gear block 54 can slide vertically inside the gear block 54.

[0028] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows: When working, the device can achieve drilling and fertilizing at the same time, and finally put the seedlings into the pit. The staff first needs to start the servo motor 23, and then the servo motor 23 drives the synchronous wheel 24 at the bottom to rotate, and the synchronous wheel 24 drives the worm 25 to rotate inside the first positioning block 27, and during the rotation of the worm 25, the limit head 28 and the punching head 210 are driven to rotate through the limit block 26; During the rotation of the worm 25, the worm 25 is meshed with the worm wheel 32, and the worm 25 drives the worm wheel 32 to rotate. The worm wheel 32 drives the rotating chucks 33 eccentrically installed at both ends to rotate synchronously, so that during the rotation of the rotating chuck 33, the Y-shaped lever 36 and the second positioning block 31 are pulled by the connecting rod 35 to rotate up and down, and the end of the second positioning block 31 away from the Y-shaped lever 36 drives the fitting block 37 to reciprocate and move the limit head 28 up and down, and then the limit head 28 and the punching head 210 move up and down during the rotation, so that the punching head 210 can quickly dig the holes required for seedling transplanting when it contacts the soil; When it is necessary to deeply plant agricultural seedlings, since the rotating chuck 33 is clamped at the two ends of the worm gear 32, the rotating chuck 33 with a larger diameter can be replaced after the pin rods 34 at the two ends of the worm gear 32 are pulled out, so that the rotating chuck 33 drives the connecting rod 35 to move up and down with a larger amplitude. At the same time, the connecting rod 35 will reciprocate the upper and lower amplitude of the limit head 28 through the Y-shaped lever 36 and the fitting block 37, so that the limit head 28 and the punching head 210 can dig deeper holes, which is convenient for deep planting of seedlings.

[0029] Secondly, during the rotation of the seedling group 12, the agricultural seedlings will be vertically aligned with the arc-shaped straightening slide plate 21 in turn, so that the agricultural seedlings will fall downward along the inside of the arc-shaped straightening slide plate 21. During this process, the agricultural seedlings will slide along the inner wall of the arc-shaped straightening slide plate 21 until they fall vertically into the planting pit, thereby achieving the effect of vertical landing of the seedling transplanting, avoiding the situation of tipping over and falling into the pit, thereby achieving the purpose of straightening; at the same time, when the arc-shaped straightening slide plate 21 is on the raised ground of the path, the arc-shaped straightening slide plate 21 will slide upward on the transplanter 11 and then stretch the reset spring 211. When placed on the concave ground, the arc-shaped straightening slide plate 21 moves downward so that the reset spring 211 is compressed, and then the elastic force of the reset spring 211 will cause the arc-shaped straightening slide plate 21 to automatically reset. At the same time, it can adapt to the uneven ground so that the seedlings can fall vertically into the planting hole smoothly and achieve the purpose of stabilizing and straightening the seedlings.

[0030] During the rotation of the synchronous wheel 24, the synchronous wheel 24 drives the synchronous wheel rod 42 to rotate through the synchronous belt 411, and the synchronous wheel rod 42 drives the upper plate 41 to rotate along the bottom of the dust cover 22 during the rotation. Every time the upper plate 41 rotates 180 degrees, the discharge port 44 at the top coincides with the positioning drop port 43 at the bottom of the storage barrel 410, so that the fertilizer inside the storage barrel 410 falls into the discharge port 44 through the positioning drop port 43. When the discharge port 44 does not coincide with the positioning drop port 43, the upper plate 41 blocks the positioning drop port 43 to prevent leakage. The fertilizer falling into the discharge port 44 will fall to the top of the fertilizer discharge plate 47 through the columnar groove 46. During the rotation of the upper plate 41, since the upper plate 41 and the lower plate 45 overlap, the upper plate 41 will drive the lower plate 45 to rotate synchronously, and then the lower plate 45 will drive the fertilizer and the fertilizer discharge plate 47 to rotate synchronously. When the end of the fertilizer discharge plate 47 away from the lower plate 45 is displaced into the arc groove 52, the space for the end of the fertilizer discharge plate 47 away from the lower plate 45 to move upward becomes larger, and then the fertilizer discharge plate 47 will rotate along the lower plate 45, so that the fertilizer between the upper plate 41 and the lower plate 45 slides along the dividing block 48 to the inside of the spreading block 49. Subsequently, the synchronous wheel rod 42 drives the upper plate 41 to rotate continuously, and then the upper plate 41 drives the lower plate 45 at the bottom to rotate synchronously, so as to achieve the purpose of intermittent feeding. At the same time, according to the combination of the frequency of the holes punched by the limit head 28 and the punching head 210, the fertilizer is sprinkled in while the holes are punched. In this process, the fertilizer is first gradually dispersed by the material dividing block 48, and then the dispersed fertilizer is sprinkled into the inside of the hole along the spreading block 49 according to a fixed path, so that the fertilizer is evenly distributed in the hole. Finally, the staff can rotate the L-shaped adjustment rod 53 located inside the gear block 54 so that during the process of the L-shaped adjustment rod 53 sliding up and down, the L-shaped adjustment rod 53 can drive the arc-shaped clamping ring 51, the lower plate 45, and the fertilizer discharge plate 47 to slide vertically along the upper plate 41. The larger the overlapping area between the cylindrical groove 46 inside the lower plate 45 and the discharge port 44, the less fertilizer is put in during the rotation of the upper plate 41. Conversely, the smaller the overlapping area between the cylindrical groove 46 inside the lower plate 45 and the discharge port 44, the more fertilizer is put in, thereby achieving the purpose of controlling the amount of fertilizer put in.

[0031] Another embodiment provided by the present invention: An operating method of a seedling transplanting device for agricultural planting, the seedling transplanting device method comprising the following steps: Step 1: Prepare a punching head 210 that matches the size of the target hole, and install the appropriate punching head 210 on the bottom of the limiting head 28; Step 2: According to the required pit depth, select a suitable size of the rotating chuck 33 for replacement. When replacing the rotating chuck 33, pay attention to its installation direction to ensure that the eccentric position is correct. After the installation is completed, check again whether the bayonet rod 34 is firmly inserted to prevent the rotating chuck 33 from shifting during the rotation process; Step 3: Start the servo motor 23. During the movement of the transplanter 11, the limit head 28 and the punching head 210 automatically dig holes of the same size according to the rotating chuck 33 during the rotation and lifting process. Step 4: When the seedling group 12 is released, check whether the arc-shaped straightening slide plate 21 is in a vertical state to ensure that the seedlings fall at a vertical angle. Before each seedling release, check whether the surface of the arc-shaped straightening slide plate 21 is smooth and whether there is any debris attached to avoid scratching the seedlings; Step 5: When the fertilizer inside the storage barrel 410 is exhausted, the fertilizer is put into the storage barrel 410 to ensure that the fertilizer is sufficient. After the punching head 210 punches a hole, the fertilizer discharge plate 47 is triggered to put the fertilizer; Step 6: The height of the arc-shaped clamping ring 51 and the lower plate 45 is adjusted by the L-shaped adjusting rod 53 to control the amount of fertilizer put in.
