Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a continuous seedling planting device. Background Technology

[0002] With the continuous advancement of science and technology, the level of mechanization and automation in agricultural production has been constantly improving. During this period, significant breakthroughs have also been achieved in the research and development of seedling equipment. Some advanced agricultural machinery companies abroad have begun to increase their investment in the research and development of seedling production equipment, developing relatively complete precision sowing systems that have achieved automation and intelligence in the seedling process. At the same time, new technologies such as satellite positioning systems, geographic information systems, and remote sensing technology have also been applied to the development of seeders, greatly improving their performance, versatility, and practicality. With global population growth and resource scarcity, improving agricultural production efficiency and quality has become even more important.

[0003] In current seedling planting machinery, digging holes and planting are generally accomplished by two separate mechanical structures. This undoubtedly increases the complexity of the entire device and makes it more prone to damage. Furthermore, this separate structure for planting and digging holes easily leads to poor coordination between the two processes, reducing planting efficiency and accuracy, and resulting in low planting continuity.

The seedling grabbing mechanism can grab the seedlings in the seedling conveying mechanism and place them in the rotary seeding mechanism. The rotary seeding mechanism includes a rotating holding mechanism and a placing mechanism. The rotating holding mechanism can drive the placing mechanism to rotate. Under the drive of the rotating holding mechanism, the placing mechanism can complete digging and planting sequentially from top to bottom and from outside to inside.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a continuous seedling planting device, which has the following beneficial effects:

[0019] This continuous seedling planting device utilizes the coordinated operation of a frame, a rotary seeding mechanism, a seedling grabbing mechanism, and a seedling conveying mechanism. The seedling grabbing mechanism picks up the seedlings from the seedling conveying mechanism, which are then received by a seedling receiving cup. At this point, the two pointed nozzles are in a closed state, with the seedling positioned between them. As the motor rotates, the seedling-containing placement mechanism gradually approaches the ground. Due to the conical shape of the nozzles, they press down on the ground, creating a planting pit. One end of the feeding connecting rod is rotatably connected to a triangular plate, while the other end is fixedly connected to a fixed shaft on the seedling receiving cup. Once the feeding connecting rod is fixed to the fixed shaft on the seedling receiving cup, the seedling receiving cup and its nozzles are positioned perpendicular to the ground. As the feeding shaft continues to rotate, the auxiliary arm acts as the driving crank in a crank-slider mechanism, the feeding connecting rod acts as the connecting rod, and the triangular plate acts as the driven crank. This design maintains the angle between the pointed plumb bob and the ground throughout its rotation and contact with the soil, creating a vertical planting pit upon contact. The pit is dug when the plumb bob reaches its lowest point, at which point the connection between the two support rods also contacts the lowest point of the lifting arc surface. As the motor continues to operate, the feeding shaft rotates clockwise, and the rotating seeding mechanism also rotates clockwise, bringing the connection between the two support rods to the lowest point of the lifting arc surface. With the placement mechanism further rotating clockwise, the lifting arc surface continues to press upwards on the connection between the support rods, causing the two pointed plumb bobs connected to the support rods to rotate around the second mounting hole and open outwards, allowing the seedlings between the two plumb bobs to fall into the planting pit. As the placement mechanism continues to rotate, when the connection between the support rods leaves the highest point of the lifting arc surface, the spring between the plumb bobs closes again, initiating the next round of seedling loading and placement. This achieves the effect of completing both digging and planting with a single mechanism, resulting in high planting efficiency, precision, and continuity. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-13 A continuous seedling planting device includes a frame 100, a rotary seeding mechanism 200, a seedling grasping mechanism 300, and a seedling conveying mechanism 400. The rotary seeding mechanism 200, the seedling grasping mechanism 300, and the seedling conveying mechanism 400 are respectively fixedly installed in the frame 100. The seedling conveying mechanism 400 transports seedlings to below the seedling grasping mechanism 300, so that the seedling grasping mechanism 300 can grasp the seedlings in the seedling conveying mechanism 400. The seedling grasping mechanism 300 can grasp the seedlings in the seedling conveying mechanism 400 and place them in the rotary seeding mechanism 200. The rotary seeding mechanism 200 includes a rotating holding mechanism 210 and a placing mechanism 220. The rotating holding mechanism 210 can drive the placing mechanism 220 to rotate. Under the drive of the rotating holding mechanism 210, the placing mechanism 220 can complete the digging and planting sequentially from top to bottom and from outside to inside.

[0036] The rotating holding mechanism 210 includes a feeding shaft 215, with bearing seats 218 mounted at both ends of the feeding shaft 215. The bearing seats 218 are fixedly mounted on the frame 100. One end of the feeding shaft 215 is also equipped with a pulley 217, on which a transmission belt is mounted. The transmission belt is connected to a motor in the frame 100. The feeding shaft 215 can drive the Ferris wheel 216 fixedly mounted on it to rotate, further driving the placement mechanism 220 to rotate, thereby completing the operations of receiving seedlings, digging holes, and placing seedlings. The bearing seats 218 fix the position of the feeding shaft 215. The pulley 217 is used to mount the transmission belt, which is connected to the motor. The pulley 217 transmits the power of the motor to the feeding shaft 215 through the transmission belt, thus realizing a series of operations.

[0037] A fixing plate 212 is provided on the frame 100, which is mounted on the bearing housing 218 away from the pulley 217. The fixing plate 212 includes a mounting plate 2122, a cylinder 2123, and a through hole 2124. The mounting plate 2122 is fixedly connected to the frame 100. A feeding shaft 215 passes through the through hole 2124, and a roller 2121 is mounted on the cylinder 2123. The main function of the fixing plate 212 is to mount the triangular plate 211, allowing the triangular plate 211 to rotate on the fixing plate 212, thereby fixing the direction of the plumb bob 222. The fixing plate 212 is fixed to the frame 100 by the mounting plate 2122. The through hole 2124 is used to pass through the feeding shaft 215, so that both ends of the feeding shaft 215 can be connected to the bearing housing 218. The diameter of the through hole 2124 is larger than the diameter of the feeding shaft 215, so it will not affect the rotation of the feeding shaft 215. A cylinder 2123 is mounted on the surface of the fixed plate 212 near the triangular plate 211. Rollers 2121 are mounted on the cylinder 2123 and can rotate around it. There are three cylinders 2123, forming an equilateral triangle. The triangular plate 211 is fastened to the outer side of each of the three rollers 2121. The three cylinders 2123 are arranged in a circular pattern, allowing the circular holes 2111 on the triangular plate 211 to engage with the three rollers 2121, further enabling the triangular plate 211 to move in a circular motion around the three rollers 2121.

[0038] A round hole 2111 is provided in the middle of the triangle plate 211, which engages with the outer side of the three rollers 2121. The triangle plate 211 can move in a circle around the three rollers 2121. Mounting holes 2112 are provided on the three corners of the triangle plate 211. The round hole 2111 is used to engage with the three rollers 2121, thereby fixing the triangle plate 211 to the inner side of the fixing plate 212. Each of the mounting holes 2112 on the three corners of the triangle plate 211 is equipped with a feeding connecting rod 213 that can rotate around the mounting hole 2112.

[0039] Four Ferris wheels 216 are mounted on the feeding shaft 215. Each Ferris wheel 216 has an auxiliary arm 214, and a placement mechanism 220 is located between the auxiliary arms 214. The placement mechanism 220 includes a seedling cup 221 and two nozzles 222, each rotatably mounted on the outside of the seedling cup 221. Support rods 224 are mounted on the outside of each nozzle 222, and the other ends of the support rods 224 are rotatably connected to each other. A retaining link 223 is also provided between the two nozzles 222. A lifting guide rail 230 is provided at the bottom of the frame 100, and a lifting arc surface 231 is provided on the lifting guide rail 230. Each Ferris wheel 216 has three auxiliary arms 214, which are arranged at 120° intervals. The Ferris wheels 216 are used to mount the auxiliary arms 214, allowing the three placement devices to work in turn, improving work efficiency. The seedling cup 221 can catch the seedlings that slip out of the seedling grasping mechanism 300 when it reaches below the seedling grasping mechanism 300.

[0040] A fixed shaft 2211 is provided on the seedling cup 221. The fixed shaft 2211 near the triangular plate 211 is rotatably connected to the auxiliary arm 214, and the fixed shaft 2211 near the triangular plate 211 passes through the auxiliary arm 214 and is fixedly connected to the corresponding feeding connecting rod 213. The auxiliary arm 214, the feeding connecting rod 213, and the triangular plate 211 form a crank-slider mechanism to control the placement mechanism 220 to always be perpendicular to the ground. When the feeding shaft 215 rotates, the auxiliary arm 214 is equivalent to the driving crank in the crank-slider mechanism, the feeding connecting rod 213 is equivalent to the connecting rod in the crank-slider mechanism, and the triangular plate 211 is equivalent to the driven crank in the crank-slider mechanism. Thus, the angle between the pointed plumb bob 222 and the ground can be maintained at all times during rotation and contact with the ground.

[0041] A trigger rod 219 is fixedly mounted on the fixed shaft 2211 where the two seedling cups 221 are close to each other. The trigger rod 219 controls the picking and placing of the seedling grasping mechanism 300. The trigger rod 219 not only fixes the two seedling cups 221 at the same height together, ensuring that the placement device at the same height remains perpendicular to the ground, but also triggers the seedling grasping mechanism 300 when the rotary seeding mechanism 200 runs to the bottom of the seedling grasping mechanism 300, causing the seedling grasping mechanism 300 to place the seedling in the nozzle 222, completing the subsequent planting.

[0042] Working principle: After the seedling grabbing mechanism 300 grabs the seedling from the seedling conveying mechanism 400, it is received by the seedling receiving cup 221. At this time, the two pointed nozzles 222 are in a closed state, and the seedling is located between the two pointed nozzles 222. As the motor runs, the seedling placement mechanism 220 gradually approaches the ground. Due to the conical shape of the pointed nozzles 222, they can press down on the ground to create a planting pit. Because one end of the feeding connecting rod 213 is rotatably connected to the triangular plate 211, and the other end of the feeding connecting rod 213 is fixedly connected to the fixed shaft 2211 on the seedling cup 221, after the feeding connecting rod 213 is fixedly connected to the fixed shaft 2211 on the seedling cup 221, the seedling cup 221 and its nozzle 222 are positioned perpendicular to the ground. When the feeding shaft 215 continues to rotate, the auxiliary arm 214 is equivalent to the active crank in the crank-slider mechanism, the feeding connecting rod 213 is equivalent to the connecting rod in the crank-slider mechanism, and the triangular plate 211 is equivalent to the driven crank in the crank-slider mechanism. Thus, the angle between the nozzle 222 and the ground can be maintained throughout the rotation and contact with the ground, leaving a vertical planting pit on the ground after contact. When the nozzle 222 reaches the lowest point, the planting pit is dug, and at this time, the connection point of the two support rods 224 also just contacts the lowest point of the lifting arc surface 231. As the motor continues to run, the feeding shaft 215 rotates clockwise, and the rotating seeding mechanism 200 rotates clockwise, causing the connection between the two support rods 224 to contact the lowest point of the lifting arc surface 231. As the placement mechanism 220 rotates further clockwise, the lifting arc surface 231 presses upwards at the connection of the support rods 224, causing the two pointed nozzles 222 connected to the support rods 224 to rotate around the mounting hole 2112 and open outwards, allowing the seedlings between the two nozzles 222 to fall into the planting pit. As the placement mechanism 220 continues to rotate, when the connection of the support rods 224 disengages from the highest point of the lifting arc surface 231, the two nozzles 222 close again due to the tension spring between them, allowing for the next round of seedling loading and placement. This achieves the effect of completing both digging and planting with a single mechanism, resulting in high planting efficiency, high precision, and high continuity.
