[0001] This utility model relates to the field of agricultural technology, specifically to a seedling 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] Currently, in most automated seedling planting devices, the seedling placement mechanism is prone to jamming when placing the seedling into the planting pit, resulting in the seedling not being placed in the planting pit or being placed inaccurately, indicating structural instability. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a seedling device with a placement mechanism that can stably and accurately place seedlings in the planting pit. This structure is more stable and reliable, solving the problem in most current automatic seedling planting devices where the placement mechanism is prone to jamming when placing seedlings in the planting pit, resulting in seedlings not being placed in the planting pit or being placed inaccurately.

[0006] (II) Technical Solution

[0007] To achieve the goal of making the above-mentioned placement mechanism more stable and reliable in accurately placing seedlings in the planting pit, the present invention provides the following technical solution: A seedling device, comprising a frame, a seedling placement mechanism, a seedling grasping mechanism, and a seedling conveying mechanism. The seedling placement mechanism, the seedling grasping mechanism, and the seedling conveying mechanism are respectively fixedly assembled in the frame. The seedling conveying mechanism transports the seedlings to below the seedling grasping mechanism, so that the seedling grasping mechanism can grasp the seedlings in the seedling conveying mechanism. The seedling grasping mechanism can grasp the seedlings in the seedling conveying mechanism and place them in the seedling placement mechanism. The seedling placement mechanism includes a transmission mechanism and a placement mechanism. The transmission mechanism can drive the placement mechanism to rotate, so that the placement mechanism places the seedlings in the placement mechanism into the planting pit from top to bottom. The placement mechanism can be opened and closed to realize the placement of the seedlings.

[0008] Preferably, the transmission mechanism includes a feeding shaft, with bearing seats at both ends of the feeding shaft, the bearing seats being fixed to the frame, and a pulley being provided on the inner side of the bearing seat at one end of the feeding shaft, with a transmission belt mounted on the pulley, and the transmission belt being connected to a motor inside the frame.

[0009] Preferably, the feeding shaft is provided with a toothed groove, a Ferris wheel is mounted on the toothed groove, a toothed hole is provided in the middle of the Ferris wheel, the toothed hole and the toothed groove are connected to fix the Ferris wheel on the feeding shaft, and the Ferris wheel is also provided with a mounting slot, in which an attachment arm is fixedly connected.

[0010] Preferably, a placement mechanism is installed between the two attached arms. The placement mechanism includes a seedling cup and a nozzle. The seedling cup can catch the seedlings that slip from the seedling grasping mechanism. The nozzle can hold the seedlings when closed and can place the seedlings in the planting pit when open.

[0011] Preferably, the seedling cup is a trumpet shape with openings at both the top and bottom, with the trumpet opening facing upwards to catch the seedlings. The outer side of the seedling cup is symmetrically provided with mounting bases, and the outer side of the seedling cup is also symmetrically provided with fixing shafts. The fixing shafts are rotatably connected to the attachment arm.

[0012] Preferably, the two tips are combined in a conical shape, and the top of each tip is provided with two support bars. The top of each support bar is provided with a retaining seat. The support bar is provided with mounting hole one and mounting hole two from bottom to top. The two tips are directly provided with tension springs.

[0013] Preferably, the second mounting hole and the mounting base are rotatably connected, allowing the tip to rotate around the mounting base.

[0014] Preferably, a support rod is rotatably mounted on each of the two nozzle mounting holes, and the other ends of the two support rods are rotatably connected together.

[0015] Preferably, a retaining rod is provided on the retaining seat of one of the tips, and the other end of the retaining rod is rotatably connected to the mounting hole of the other tip.

When the connection of the two support rods is separated from the highest point of the lifting arc surface, the tension spring closes the two tips back together.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a seedling device with the following beneficial effects:

[0019] This seedling device utilizes a frame, a seedling placement mechanism, a seedling gripping mechanism, and a seedling conveying mechanism working together. The seedling gripping mechanism picks up the seedlings from the seedling conveying mechanism and receives them in a receiving cup. At this point, the two pointed nozzles are closed, with the seedling positioned between them. As the motor rotates, the feeding shaft rotates clockwise, causing the placement mechanism to rotate clockwise until the connection between the two support rods contacts the lowest point of the lifting arc surface. With further clockwise rotation of the placement mechanism, the lifting arc surface continues to press upwards on the connection between the support rods, causing the two pointed nozzles connected to the support rods to rotate around the mounting hole and open outwards, allowing the seedling between the two nozzles to fall into the planting pit. As the placement mechanism continues to rotate, when the connection between the support rods moves away from the highest point of the lifting arc surface, the two nozzles close again due to the tension spring between them, allowing for the next round of seedling loading and placement. This achieves a more stable and reliable structure, ensuring the placement mechanism can accurately and stably place the seedlings within it into the planting pit. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Please see Figure 1-10 A seedling device includes a frame 100, a seedling placement mechanism 200, a seedling gripping mechanism 300, and a seedling conveying mechanism 400. The seedling placement mechanism 200, the seedling gripping mechanism 300, and the seedling conveying mechanism 400 are respectively fixedly assembled in the frame 100. The seedling conveying mechanism 400 transports seedlings to below the seedling gripping mechanism 300, so that the seedling gripping mechanism 300 can grip the seedlings in the seedling conveying mechanism 400. The seedling gripping mechanism 300 can grip the seedlings in the seedling conveying mechanism 400 and place them in the seedling placement mechanism 200. The seedling placement mechanism 200 includes a transmission mechanism 210 and a placement mechanism 220. The transmission mechanism 210 can drive the placement mechanism 220 to rotate clockwise, so that the placement mechanism 220 places the seedlings in the placement mechanism 220 into the planting pit from top to bottom. The placement mechanism 220 can be opened and closed to realize the placement of seedlings.

[0033] The transmission mechanism 210 includes a feeding shaft 212, which drives the Ferris wheel 215 mounted on it to rotate. Bearing seats 211 are respectively provided at both ends of the feeding shaft 212, and the bearing seats 211 are fixed to the frame 100, fixing the feeding shaft 212 in place. A pulley 213 is provided on the inner side of one end of the bearing seat 211 of the feeding shaft 212, and a transmission belt 216 is mounted on the pulley 213. The transmission belt 216 is connected to a motor inside the frame 100. The pulley 213 is used to mount the transmission belt 216, and it converts the rotational motion of the motor into the rotation of the pulley 213. The pulley 213 transmits the power of the motor to other moving parts through the transmission belt 216, realizing power transmission and speed control. The motor provides the necessary rotational power to drive the pulley 213 and the transmission belt 216 to move, thereby driving the unloading shaft 212 and other components to work.

[0034] The feeding shaft 212 is provided with a toothed groove 2121, on which a Ferris wheel 215 is mounted. A toothed hole 2151 is provided in the middle of the Ferris wheel 215, which mates with the toothed groove 2121 to fix the Ferris wheel 215 onto the feeding shaft 212. The Ferris wheel 215 is also provided with a mounting slot 2152, in which an auxiliary arm 214 is fixedly connected. The toothed groove 2121 and the toothed hole 2151 mate to fix the Ferris wheel 215 onto the feeding shaft 212, and the fit between them provides a more secure and reliable installation. The mounting slot 2152 on the outer side of the Ferris wheel 215 makes the installation of the auxiliary arm 214 more convenient.

[0035] A placement mechanism 220 is installed between the two attachment arms 214. The placement mechanism 220 includes a seedling cup 221 and a nozzle 222. The seedling cup 221 can catch the seedlings that slide down from the seedling grabbing mechanism 300. The nozzle 222 can hold the seedlings when closed and can place the seedlings in the planting pit when open.

[0036] The seedling cup 221 is a trumpet shape with openings at both the top and bottom, with the trumpet facing upwards to catch the seedling. A mounting base 2211 and a fixing shaft 2212 are symmetrically arranged on the outer side of the seedling cup 221. The fixing shaft 2212 is rotatably connected to the auxiliary arm 214. The mounting base 2211 and the second mounting hole 2222 are rotatably connected together by screws and nuts. The screws are passed sequentially through the second mounting hole 2222, the mounting base 2211, and the second mounting hole 2222. A nut is screwed onto the other end of the screw, allowing the nozzle 222 to rotate around the screw installed in the mounting base 2211 through the second mounting hole 2222, thus closing and opening the nozzle 222. The fixing shaft 2212 is rotatably connected between the two auxiliary arms 214, ensuring that the seedling cup 221 remains perpendicular to the ground.

[0037] The two pointed nozzles 222 are combined into a conical shape. Two support bars 2223 are provided at the top of the nozzles 2222, and a retaining seat 2224 is provided at the top of each support bar 2223. From bottom to top, the support bars 2223 have mounting holes 1 2221 and 2222 respectively. Tension springs are directly mounted on the two nozzles 222. The conical shape facilitates placing the seedling in the planting pit, reducing placement resistance. The support bars 2223 at the top of the nozzles 222 provide a base for the installation of other parts. The retaining seat 2224 at the top of the support bars 2223 is used to install the retaining rod 223. Mounting hole 1 2221 on the support bar 2223 is rotatably connected to the support rod 224 by screws and nuts, and mounting hole 2222 is rotatably connected to the mounting seat 2211 by screws and nuts. This allows the two nozzles 222 to be opened and closed by the support rod 224.

[0038] Support rods 224 are rotatably mounted on the mounting holes 2221 of the two pointed nozzles 222, and the other ends of the two support rods 224 are rotatably connected together. The other ends of the two support rods 224 are connected together by ball bearings.

[0039] A retaining rod 223 is provided on the retaining seat 2224 of one nozzle 222. The other end of the retaining rod 223 is rotatably connected to the mounting hole 2221 of the other nozzle 222. The two ends of the retaining rod 223 are rotatably connected to the retaining seat 2224 on the top of one nozzle 222 and the mounting hole 2221 of the other nozzle 222, respectively, so that the seedling cup is always in a plumb line relative to the axis of the frame. Furthermore, when the lifting guide rail 230 presses on the connection between the two support rods 224, it will not change the angle of the entire placement mechanism 220, so that the angle of the placement mechanism 220 is always downward, and the seedlings are placed in the placement pit more accurately.

[0040] A lifting guide rail 230 is provided at the bottom of the frame 100. The lifting guide rail 230 includes an upper mounting platform 2302 and a side plate 2303. The upper mounting platform 2302 and the side plate 2303 fix the lifting guide rail 230 to the bottom of the frame 100. A lifting arc surface 2301 is provided on the lifting guide rail 230. The unloading shaft 212 rotates clockwise, driving the placement mechanism 220 to rotate clockwise, so that the placement mechanism 220 rotates from the outside to the inside and from high to low until it reaches the lifting guide rail 230. At this time, when the connection of the two support rods 224 moves from the lowest point of the lifting arc surface 2301 to the highest point of the lifting arc surface 2301, the lifting arc surface 2301 will press the support rods 224 upward, thereby separating the two tips 222 to realize the placement of the seedling. When the connection of the two support rods 224 is separated from the highest point of the lifting arc surface 2301, the tension spring will close the two tips 222 together again.

[0041] Working principle: After the seedling grabbing mechanism 300 grabs the seedlings from the seedling conveying mechanism 400, they are received by the seedling receiving cup 221. At this time, the two pointed nozzles 222 are in a closed state, and the seedlings are located between the two pointed nozzles 222. As the motor runs, the feeding shaft 212 rotates clockwise, driving the placement mechanism 220 to rotate clockwise so that the connection of the two support rods 224 contacts the lowest point of the lifting arc surface 2301. As the placement mechanism 220 rotates clockwise further, the lifting arc surface 2301 will continue to rotate clockwise and press the connection of the support rods 224 upward, causing the two pointed nozzles 222 connected to the support rods 224 to rotate around the second mounting hole 2222 and open outward, so that the seedlings between the two pointed nozzles 222 fall into the planting pit. As the placement mechanism 220 continues to rotate, when the connection of the support rod 224 disengages from the highest point of the lifting arc surface 2301, the two tips 222 close again due to the tension spring action between them, allowing for the next round of seedling loading and placement. This achieves the effect of the placement mechanism 220 stably and accurately placing the seedlings in the planting pit, resulting in a more stable and reliable structure.
