Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, specifically to a seedling transplanting mechanism. Background Technology

[0002] A seedling transplanter is a mechanized device specifically designed for agriculture, forestry, and horticulture. Through automated or semi-automated operation, it transplants seedlings from the nursery area to the field or other growing environments, significantly improving transplanting efficiency and accuracy while reducing manual labor intensity. The core structure of a seedling transplanter includes: a seedling picking device, a conveying system, a planting device, and a control system. In the specific operation process, the seedlings are first separated from the seedling tray by the seedling picking device (such as a mechanical claw or vacuum suction cup). Some models require manual assistance in feeding the seedlings, while fully automatic models can complete this independently. Subsequently, the seedlings are transported to the planting port by a conveyor belt or seedling guide tube. The planter opens a trench, places the seedlings, and covers them with soil at a preset plant spacing.

[0003] During transplanting, factors such as soil physical structure, nutrient status, microbial environment, and moisture conditions directly affect the survival rate and growth quality of seedlings. To improve the survival rate, soil fertilization is typically applied before transplanting to optimize soil conditions. However, during actual transplanting, soil often clumps due to poor fertilization or insufficient organic matter content. These compacted soil particles hinder the deep or lateral root development of seedlings, leading to shallow root systems. Furthermore, the low porosity and poor aeration of clumped soil can cause root hypoxia, impacting nutrient absorption and metabolic activity. Therefore, backfilling is necessary during transplanting. If clumps remain in the backfill, they can cause direct physical damage to the seedling pot and negatively affect the growth quality of the seedlings. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The silicone rods break up the clumps of soil on the filter plate surface. The first pair of rods applies force to the load-bearing shaft, ensuring that the silicone rods do not interfere with the movement of the clumps of soil when they reach the filter plate surface. At the same time, the torsion spring continues to deform under the action of the second pair of rods, thereby controlling the force applied by the silicone rods to the filter plate surface. On the one hand, this effectively breaks up the clumps of soil, and on the other hand, the vibration force when the silicone rods come into contact with the filter plate surface helps to clear the filter pores on the filter plate, preventing the pores from being blocked by soil.

[0018] 3. When encountering multiple clumps of soil, this seedling transplanting mechanism can use the resistance provided by the clumps to break up the frame, allowing the frame to adjust its angle and completely break up the soil, thus avoiding physical damage to the base of the seedling pot when the clumps are backfilled.

[0032] 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.

[0033] Please see Figure 1-12This invention relates to a seedling transplanting mechanism. It addresses the technical problems mentioned in the background section by preventing the detachment of the substrate's potting soil and preventing direct physical damage to the seedling pot substrate from clumped soil backfill. The mechanism includes a conveying mechanism 2 mounted on a body 1, with a moving mechanism 4 on one side for moving the seedling tray body 3. The moving mechanism 4 is mounted on the body 1. The body 1 also includes a hydraulic seedling-retrieving mechanism 5. A planting mechanism 6 for planting the seedlings in the pots is located at the bottom of the body 1. It should be noted that the planting mechanism 6 and the "transfer duckbill mechanism 8" mentioned below are both composed of angle-adjustable duckbill mechanisms. During material retrieval, the duckbill mechanism is in a closed state. When the seedling pot enters the duckbill mechanism and planting is required, the angle of the duckbill mechanism 6 is adjusted. During the process, the duckbill in the planting mechanism 6 pries open the soil, and the seedling pot falls into the soil under the action of gravity. The above operations are all existing technologies, and therefore the present invention does not describe them in detail. An extension frame 13 is fixedly installed on the upper end of the machine body 1, and a shovel 14 that penetrates into the soil is also fixedly installed on the extension frame 13. A filter plate 141 for filtering soil is also fixedly installed on the shovel 14. A rotating shaft 131 rotatably connected to the extension frame 13 is also installed on the extension frame 13. A torsion spring 132 is also connected between the end of the rotating shaft 131 and the extension frame 13. An installation plate frame 133 is also fixedly installed on the rotating shaft 131. Multiple silicone rod frames 134 for breaking up clumps of soil are also fixedly installed on the installation plate frame 133. The filter plate 141 is located on the movement trajectory of the silicone rod frame 134. Figure 2 and attached Figure 3 As shown, multiple silicone shafts corresponding to the filter holes on the filter plate 141 are also fixedly installed on the silicone rod frame 134. It should be noted that when the torsion spring 132 is not deformed, the silicone rod frame 134 is in contact with the surface of the filter plate 141. When the silicone rod frame 134 is not in contact with the surface of the filter plate 141, the torsion spring 132 deforms. The extension frame 13 is also equipped with a transmission unit 15 for driving the rotating shaft 131 to move. The transmission unit 15 causes the rotating shaft 131 to drive the mounting plate frame 133 to move, thereby controlling the silicone rod frame 134 to break up the clumps of soil on the filter plate 141.

[0034] As a further limitation of the present invention, the transmission unit 15 includes a motor body 151 fixedly mounted on the extension frame 13, and a transmission shaft 152 rotatably connected to the inner wall of the extension frame 13 is also installed inside the extension frame 13. One end of the transmission shaft 152 is fixedly connected to the output end of the motor body 151, and a circular panel 153 is symmetrically mounted on the transmission shaft 152, wherein a plurality of actuating rods 154 and actuating rods 155 are fixedly mounted on the circular panel 153; in conjunction with the appendix Figure 5As shown, the length of the first action rod 154 in this invention is less than the length of the second action rod 155; and a force-receiving disk 135 is symmetrically mounted on the rotating shaft 131, wherein the force-receiving disk 135 is provided with a slot 136, and a sliding block 137 is installed in the slot 136 and slidably connected to its inner wall. A constant force spring 138 is also connected between the sliding block 137 and the slot 136. A force-receiving shaft 139 is fixedly mounted on one side of the sliding block 137, and the force-receiving shaft 139 is located on the movement trajectory of the first action rod 154 and the second action rod 155. A telescopic part 130 is fixedly mounted on the side of the sliding block 137 away from the force-receiving shaft 139, and a telescopic part 130 is opened on the side wall of the extension frame 13. The guide groove 16 contains a telescopic part 130 that slides within it. The guide groove 16 includes an arc-shaped region 161 and an arc-shaped region 162, where the depth of the arc-shaped region 162 is greater than that of the arc-shaped region 161. Two guide panels 163 are fixedly installed within the arc-shaped region 162, each with an inclined surface on one side and a right-angled surface on the other. The telescopic part 130 is made of magnetic material, and an arc-shaped magnetic block 164 is fixedly installed on the inner wall of the extension frame 13. The arc-shaped magnetic block 164 is located on the movement trajectory of the telescopic part 130. When the telescopic part 130 moves to the position of the arc-shaped magnetic block 164, the arc-shaped magnetic block 164 will exert an attractive force on the telescopic part 130. Figure 8 As shown, in this invention, one of the two guide panels 163 is located at the intersection of arc-shaped region two 162 and arc-shaped region one 161. When entering arc-shaped region one 161 from arc-shaped region two 162, the telescopic part 130 passes through the inclined surface of the guide panel 163 and moves from the attached... Figure 8 As can be seen, the arc-shaped region 161 and arc-shaped region 162 in this invention are similar in shape to an "L-shape". Another guide panel 163 is located at the corner of arc-shaped region 162. When the telescopic part 130 moves from the intersection of arc-shaped region 161 and arc-shaped region 162 to the corner of arc-shaped region 162, the telescopic part 130 will pass through the inclined surface of the guide panel 163. Since there is a height difference between arc-shaped region 161 and arc-shaped region 162, the telescopic part 130 will return from the compressed state to the normal state during the process of moving from arc-shaped region 161 to arc-shaped region 162. That is, the telescopic part 130 is in the compressed state in arc-shaped region 161.

[0035] In actual use, during the process of the hydraulic seedling picking mechanism 5 transferring the seedling pot to the planting mechanism 6, the seedling pot falls into the planting mechanism 6 by gravity. During this process, due to the large height difference between the two, the base of the seedling pot will be subjected to a certain impact force when it comes into contact with the inner wall of the planting mechanism 6, which can easily cause the base to fall off the seedling pot. In order to reduce this impact force, the present invention makes the following design: a chain drive mechanism 7 is also installed on the machine body 1, and multiple transfer duck tongue mechanisms 8 are fixedly installed on the chain drive mechanism 7. After the hydraulic seedling picking mechanism 5 takes out the seedling pot, it is transported into the transfer duck tongue mechanism 8, wherein the planting mechanism 6 is located on the movement trajectory of the transfer duck tongue mechanism 8;

[0036] Combined with appendix Figure 7 As shown, the hydraulic seedling taking mechanism 5 is activated to remove the seedling pot from the seedling tray 3, and then lowers to transfer the seedling pot into the duck tongue transfer mechanism. At this time, the duck tongue on the duck tongue transfer mechanism is in a closed state. Through this design, the impact force between the seedling pot and the inner wall of the duck tongue transfer mechanism is greatly reduced. Then, the duck tongue transfer mechanism is moved above the planting mechanism 6 by the chain rotation mechanism. The planting mechanism 6 moves upward. When it rises to the end, the bottom of the duck tongue transfer mechanism is inside the planting mechanism 6. Then, the duck tongue transfer mechanism adjusts its angle, and the seedling pot inside it falls into the planting mechanism 6. At this time, the height difference between the two is small, which can effectively reduce the impact force when the seedling pot contacts the inner wall of the planting mechanism 6. It should be noted that the planting mechanism 6 in the prior art plants the seedling pot by lifting and lowering, and the planting mechanism 6 is a prior art component. Therefore, this invention does not describe it in detail.

[0037] Following the above, during the transplanting process, small clumps of soil may still remain on the surface of the treated soil. To reduce the impact of these clumps on the growth of the seedlings, this invention further treats the clumps. To address this, the invention is designed as follows: A belt drive mechanism 9 is also installed on the machine body 1. One end of the belt drive mechanism 9 is fixedly connected to the wheel axle of the machine body 1, and a drive shaft 10 is fixedly installed on the other end of the belt drive mechanism 9. The drive shaft 10 is rotatably connected to the machine body 1, and a shaft-shaped magnetic roller 101 is fixedly installed on the drive shaft 10. Below 01, a mechanism 11 for breaking up compacted soil is provided. The axial magnetic roller 101 consists of two N-pole regions 102 and S-pole regions of equal area. A guide shaft 104 is symmetrically fixedly installed on the machine body 1 with the center line of the axial magnetic roller 101 as the axis. A drive plate frame 105 is mounted on the guide shaft 104 and slidably connected to its outer wall. An axial magnet 106 with S-pole magnetism is also fixedly installed on the drive plate frame 105. The axial magnet 106 is located below the axial magnetic roller 101, and a return spring 107 is sleeved on the guide shaft 104. One end is connected to the body 1, and the other end is connected to the drive plate frame 105. The actuating mechanism 11 is mounted on the drive plate frame 105. The actuating mechanism 11 includes an actuating sleeve 111 fixedly mounted on the drive plate frame 105, and an annular plate frame 112 is installed inside the actuating sleeve 111. A telescopic shaft 113 is also installed on the annular plate frame 112. The inner wall of the actuating sleeve 111 has multiple snap-fit ​​grooves 12, which are in a communicating state. The telescopic shaft 113 slides within the multiple snap-fit ​​grooves 12. A connecting shaft 114 is fixedly mounted on the lower surface of the annular plate frame 112. The end of the body 114 penetrates the inner wall of the working sleeve 111 and extends to the outside. A crushing rod frame 115 is fixedly installed at one end of the connecting shaft 114 located outside the working sleeve 111. The crushing rod frame 115 in this invention has a triangular cross-section for crushing clumps of soil. A spring mechanism 116 connects the annular plate frame 112 to the inner wall of the working sleeve 111. The locking groove 12 includes a sliding area 121, a spiral area 122 communicating with the sliding area 121, and a guide plate frame 123. One side of the guide plate frame 123 is an inclined surface, and the other side is a right-angled surface. It should be noted that, in conjunction with the attached... Figure 11 and attached Figure 12 As shown, the guide plate frame 123 is installed at the intersection of the highest point of the sliding area 121 and the spiral area 122. The inclined surface of the guide plate frame 123 is located within the sliding area 121, and the right angle surface is located at the intersection of the sliding area 121 and the spiral area 122.

[0038] Specifically, during the transplanting process, the shovel body 14 comes into contact with the soil, and under the action of the shovel body 14, the soil passes through the filter plate 141. The filter plate 141 filters the soil, leaving clumps of soil on its surface. Then, the operator starts the motor body 151. The output end of the motor body 151 drives the circular panel 153 to rotate via the transmission shaft 152. During the rotation of the circular panel 153, the first and second action rods 154 and 155 on it rotate synchronously. When the silicone rod 134 is in contact with the surface of the filter plate 141, the torsion spring 132 is in its normal state, and at this time, the telescopic part 130... Located at the initial end of the arc-shaped region 161, as the first action rod 154 and the second action rod 155 rotate with the circular panel 153, the force-bearing shaft 139 is located on the motion trajectory of the first action rod 154 and the second action rod 155. As a result, the first action rod 154 and the second action rod 155 will exert a force on the force-bearing shaft 139 during rotation. This allows the force-bearing shaft 139 to drive the force-bearing disc 135 to rotate through the sliding block 137. That is, the force-bearing disc 135 drives the mounting plate 133 and the silicone rod 134 on it to rotate through the rotating shaft 131. At this time, the torsion spring 132 is in a deformed state.

[0039] Since the length of the first actuating rod 154 is less than the length of the second actuating rod 155, when the silicone rod 134 is in contact with the surface of the filter plate 141 (i.e., the torsion spring 132 is in its normal state), the first actuating rod 154 first contacts the force-bearing shaft 139 and applies a force to it. The force-bearing shaft 139 rotates under the force, which in turn causes the sliding block 137 to drive the force-bearing disk 135 to rotate. During the rotation of the sliding block 137, the telescopic part 130 on it moves from the initial end of the arc-shaped region 161. When the telescopic part 130 moves from the arc-shaped region 161 to the arc-shaped region 16... At point 2, the torsion spring 132 is in a deformed state, but the telescopic part 130 returns to its normal state. When the telescopic part 130 moves towards the arc-shaped region 161 under the action of the torsion spring 132, it is obstructed by the intersection of the arc-shaped region 161 and the arc-shaped region 162. When the telescopic part 130 moves from the arc-shaped region 161 into the arc-shaped region 162, the actuating rod 154 separates from the force-bearing shaft 139, meaning that a certain amount of clumps of mud accumulate on the surface of the filter plate 141. It should be noted that the motor body 151 can be a worm gear reducer to ensure that the output end of the motor body 151 is in a slow-moving state. In a slow-rotation state, it facilitates the accumulation of clumps of soil on the surface of the filter plate 141. Subsequently, the second actuating rod 155 contacts the force-bearing shaft 139 and applies force to it, causing the telescopic part 130 to move along the trajectory of the arc-shaped region 162. When the telescopic part 130 moves to the corresponding position of the arc-shaped magnetic block 164, since the telescopic part 130 is made of magnetic material and the arc-shaped magnetic block 164 will generate an attractive force on the telescopic part 130, the telescopic part 130 will move towards the arc-shaped magnetic block 164. During the movement, the sliding block 137 will compress the constant force spring 138, thereby causing the force-bearing shaft 139 to move away from the actuating rod 155. On the trajectory of the second rod 155, under the action of the deformed torsion spring 132, the telescopic part 130 moves along the trajectory of the second arc region 162 to the first arc region 161. During this process, the telescopic part 130 passes through the inclined surface of one of the guide panels 163, that is, the telescopic part 130 is in a compressed state again, while the torsion spring 132 changes from the deformed state to the normal state, so that the multiple silicone rods 134 on the mounting plate 133 can break up the clumps of soil on the surface of the filter plate 141, and the telescopic part 130 will return to the initial end of the first arc region 161 under the action of the compressed constant force spring 138.Furthermore, through the design of this invention, the silicone rod 134 breaks up the clumps of soil on the surface of the filter plate 141. The first actuating rod 154 applies force to the force-bearing shaft 139, ensuring that the silicone rod 134 does not interfere with the movement of the clumps of soil when it reaches the surface of the filter plate 141. Simultaneously, the second actuating rod 155 causes the torsion spring 132 to continue deforming, thereby controlling the force applied by the silicone rod 134 to the surface of the filter plate 141. This effectively breaks up the clumps of soil, and the vibration force from the silicone rod 134 contacting the surface of the filter plate 141 helps to clear the filter holes on the filter plate 141, preventing them from being blocked by soil.

[0040] As described above, during the movement of the machine body 1, the wheel axle on the machine body 1 will drive the drive shaft 10 to rotate through the belt transmission mechanism 9. The shaft-shaped magnetic roller 101 on the drive shaft 10 will rotate synchronously with it, and the N pole region 102 and S pole region 103 of the shaft-shaped magnetic roller 101 will change. When the N pole region 102 is directly above the shaft-shaped magnet 106 with S pole, the shaft-shaped magnet 106 is attracted by the attraction force, which drives the drive plate frame 105 to move upward along the guide shaft 104. At this time, the reset spring 107 is in a compressed state, and the crushing rod frame 115 is not in contact with the soil. When the S pole region 103 moves to directly above the shaft-shaped magnet 106 with S pole, the S pole region 103 will generate a repulsive force on the shaft-shaped magnet 106. Then, under the action of the drive plate frame 105, the crushing rod frame 115 will move downward. During the descent, the crushing rod frame 115 will crush the clumps of soil.

[0041] When the soil still contains a significant amount of compacted soil, the crushing rod 115 only crushes the compacted soil in a single direction. Some of the compacted soil may not be completely crushed. Therefore, when there is a large amount of compacted soil, the crushing rod 115 will encounter resistance during descent. Under the action of the connecting shaft 114, the annular plate 112 will stretch the spring mechanism 116. Preferably, the spring mechanism 116 of this invention has a low spring coefficient. When there is a large amount of compacted soil, the telescopic shaft 113 will move upwards along the sliding area 121. When the crushing rod 115 leaves the soil, the connecting shaft 114 on the annular plate 112 will cause the crushing rod 115 to return to its original position under the action of the spring mechanism 116. At this time, the telescopic shaft 113 will... Under the action of the right-angled surface of the guide plate frame 123, it moves along the trajectory of the spiral region 122, so that the connecting shaft 114 drives the breaking rod frame 115 to adjust its angle. When encountering multiple clumps of soil, the direction of the breaking rod frame 11573 can be changed to completely break up the soil, thereby avoiding physical damage to the base of the seedling pot when the clumps of soil are backfilled. If there are few clumps of soil, the resistance experienced by the breaking rod frame 115 is relatively low, and the telescopic shaft 113 on the annular plate frame 112 will move along the trajectory of the sliding region 121 and will not pass through the inclined surface of the guide plate frame 123. Thus, through the structural design of the present invention, clumps of soil can be effectively treated before planting, avoiding physical damage to the base of the seedling pot when the clumps of soil are backfilled, thereby improving the planting quality.
