Description

Technical Field

[0001] This utility model relates to the field of forestry transplanting technology, and more specifically, to a forestry seedling transplanting device. Background Technology

[0002] The forestry seedling transplanting device is a mechanized tool specifically designed for seedling cultivation and transplantation. It is mainly used to improve transplanting efficiency, reduce labor intensity, and ensure seedling survival rate. It is especially suitable for complex terrains such as hilly and mountainous areas. The forestry seedling transplanting device solves the problems of high labor input, many terrain restrictions, and low survival rate in traditional forestry transplanting through mechanization, and provides key technical support for modern intensive forestry production.

[0003] Traditional forestry seedling transplanting equipment lacks an effective shock absorption system. When traveling in rugged forest environments such as hills and mountains, the vehicle often experiences severe vibrations. This continuous and intense vibration causes serious physical damage to the seedlings inside the vehicle. The vibration can easily cause the root ball of the seedlings to loosen or even break, destroying the integrity of the root-soil bond. At the same time, the stems and leaves collide with each other or rub against the container due to frequent shaking, causing mechanical damage. This directly affects the physiological state and survival ability of the seedlings, seriously restricting the survival rate after transplanting.

[0004] In summary, to improve the survival rate of transplanted seedlings, it is necessary to address the problem that traditional forestry seedling transplanting equipment lacks an effective shock absorption system, which leads to loose or even broken root clumps, affecting the physiological state and survival ability of seedlings. The goal is to enable transplanting devices to adapt to various terrains and carry out stable transplanting operations. Utility Model Content

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Refer to the instruction manual appendix Figures 1 to 5A forestry seedling transplanting device includes a frame 1, with multiple hinged supports 2 fixedly connected to the frame 1. A mounting frame 3 is fixedly connected to the hinged supports 2, and a first motor 4 is fixedly connected to the mounting frame 3. The output end of the first motor 4 is fixedly connected to a wheel 5 via a shaft. The wheel 5 is rotatably connected to the mounting frame 3 via a shaft. The first motor 4 drives the wheel 5 to rotate. Two symmetrical hydraulic dampers 6 are fixedly connected between the mounting frame 3 and the frame 1. Shock-absorbing springs 7 are sleeved on the outer side of the hydraulic dampers 6 and fixedly connected between the mounting frame 3 and the frame 1. A multi-layer seedling tray frame 12 and a seedling guide tube 18 are fixedly connected to the frame 1. Micro motors 19 are fixedly connected to both sides of the bottom of the seedling guide tube 18. A duckbill clip 20 is fixedly connected to the output end of the micro motor 19 via a shaft. The duckbill clip 20 is rotatably connected to the bottom of the seedling guide tube 18, and the micro motor 19 drives the duckbill clip 20 to rotate.

[0024] It should be noted that the articulated supports 2 are located at the four corners of the frame 1, and then the wheels 5 controlled by individual motors are installed on the articulated supports 2 to enable the free movement of the frame 1. The frame 1 has high rigidity and strength to withstand various loads. The multi-layer seedling tray rack 12 is installed on the frame 1, which allows seedlings to be taken layer by layer or continuously during operation, reducing the downtime of adding seedlings in the middle, and is suitable for large-scale transplanting operations.

[0025] It is worth noting that the articulated support 2 and the mounting bracket 3 together form a suspension rocker arm. The articulated support 2 connects the mounting bracket 3 to the frame 1 and allows the mounting bracket 3 to swing up and down within a certain range around the articulation point, thus realizing the basic structure for shock absorption. The shock absorber spring 7 supports the weight and buffers the impact. When the wheel 5 encounters a bump or dent, the shock absorber spring 7 is compressed or stretched, absorbing most of the impact energy. At the same time, the hydraulic damper 6 is used to suppress the repeated bouncing of the shock absorber spring 7. Through the damping effect of the hydraulic oil, the impact energy absorbed by the shock absorber spring 7 is converted into heat energy and dissipated, so that the vehicle can quickly return to stability after bumps and avoid the body from shaking continuously.

[0026] Refer to the instruction manual appendix Figure 3 A lifting assembly is installed at one end of the frame 1. The output end of the lifting assembly is connected to a first slider 9. The lifting assembly is used to drive the first slider 9 to perform vertical linear motion. A third motor 10 is fixedly connected to the first slider 9. A screw rod 11 is fixedly connected to the output end of the third motor 10. The screw rod 11 is rotatably connected to the first slider 9. The third motor 10 is used to drive the screw rod 11 to rotate.

[0027] It should be noted that the lifting assembly is located at the front end of the frame 1 in the direction of travel. The third motor 10 drives the screw rod 11 to rotate, which, in conjunction with the lifting assembly, drives the screw rod 11 to move downward to open a hole, thus preparing for subsequent transplanting.

[0028] Refer to the instruction manual appendix Figure 3 The lifting assembly includes a guide rail 801 fixedly connected to the frame 1, a second motor 802 fixedly connected to the guide rail 801, a threaded rod 803 fixedly connected to the output end of the second motor 802, and two guide rods 804 symmetrically fixedly connected to the guide rail 801. The threaded rod 803 is rotatably connected to the guide rail 801, and the threaded rod 803 is threadedly connected to the first slider 9. The guide rods 804 are slidably connected to the first slider 9. The second motor 802 is used to drive the threaded rod 803 to rotate.

[0029] It should be noted that the two guide rods 804 are symmetrically located on both sides of the threaded rod 803. The first slider 9 has a threaded hole in the center and through holes on both sides of the threaded hole. The size of the threaded hole is adapted to the threaded rod 803 to realize the linear movement of the first slider 9. The size of the through holes is adapted to the guide rod 804 to limit the movement of the first slider 9.

[0030] Refer to the instruction manual appendix Figure 6 The other end of the frame 1 is equipped with a soil compaction assembly. The output end of the soil compaction assembly is connected to two symmetrical soil compaction wheels 22. The soil compaction assembly is used to drive the two soil compaction wheels 22 to change their angle.

[0031] It should be noted that the soil compaction assembly is located at the rear end of the frame 1 in the direction of travel. After the seedlings have been placed into the transplanting holes, the soil compaction assembly is used to control the angle between the two soil compaction wheels 22, so that the soil compaction wheels 22 compact the soil, so that the roots are in full contact with the soil and the plants remain upright.

[0032] Refer to the instruction manual appendix Figure 6 The soil compaction assembly includes an electric push rod 2101 fixedly connected to the frame 1, a connecting rod 2102 fixedly connected to the output end of the electric push rod 2101, and two connecting frames 2103 with one end rotatably connected to both ends of the connecting rod 2102. The other end of the connecting frame 2103 is rotatably connected to a soil compaction wheel 22. The connecting frame 2103 is rotatably connected to the frame 1. The electric push rod 2101 is used to drive the connecting rod 2102 to move in a preset direction.

[0033] It should be noted that the electric push rod 2101 is installed at the rear end of the frame 1 and is used to push the connecting rod 2102 to move linearly. The connecting frames 2103 on both sides of the connecting rod 2102 are symmetrical about the center of the electric push rod 2101, so that the power is synchronously distributed to the left and right connecting frames 2103, ensuring that the soil compaction wheels 22 on both sides move in unison and rise or pressurize synchronously.

[0034] It is worth noting that the connecting frame 2103 is an L-shaped or V-shaped rigid rod, which essentially constitutes a lever mechanism. The extension and retraction of the electric push rod 2101 changes the connection position between the connecting frame 2103 and the connecting rod 2102. Through the lever principle, the connecting frame 2103 is driven to make an arc motion with the connection position between the connecting frame 2103 and the soil compaction wheel 22 as the center, thereby realizing its lifting and lowering and changing the pressure on the ground.

[0035] Refer to the instruction manual appendix Figure 4 A cross module 13 is fixedly connected to the frame 1. A second slider 14 is fixedly connected to the output end of the cross module 13. The cross module 13 is used to drive the second slider 14 to move in a preset direction.

[0036] It should be noted that the cross module 13 is a precision motion platform that integrates the X and Y axes, forming a two-dimensional planar motion system, which is used to control the second slider 14 to move linearly in both the vertical and horizontal directions of the frame 1 at the same time.

[0037] Refer to the instruction manual appendix Figure 4 The bottom of the second slider 14 is fixedly connected to a fourth motor 15. The output end of the fourth motor 15 is fixedly connected to a linear module 16 via a shaft. The fourth motor 15 is used to drive the linear module 16 to rotate. The output end of the linear module 16 is fixedly connected to an electric gripper 17. The linear module 16 is used to drive the electric gripper 17 to move along a preset direction.

[0038] It should be noted that the fourth motor 15 is used to drive the linear module 16 to rotate, so that the linear module 16 will not cause motion interference when transplanting seedlings of different heights. The electric gripper 17 is a two-finger gripper of a small motor. Its fingertips are specially designed according to the size and shape of the seedling pot, such as having tapered, corrugated or soft pads, to ensure that it can firmly grip the seedling pot, while not squeezing it excessively to prevent it from falling apart or damaging the stem.

[0039] Working principle: The first motor 4 drives the wheels 5 to rotate, causing the frame 1 to move in the field. During the movement, the independent suspension damping system, composed of the articulated support 2, mounting frame 3, hydraulic damper 6, and shock absorber spring 7, effectively buffers bumps and ensures vehicle stability. Simultaneously, the second motor 802 drives the threaded rod 803 to rotate, causing the first slider 9 to move linearly downwards along the guide rod 804. At the same time, the third motor 10 drives the auger 11 to rotate, drilling it into the soil to create planting holes. Then, the cross module 13 on the frame 1 drives the second slider 14 to the target seedling pot layer height. Then, the fourth motor 15 drives the linear module 16 to rotate, changing the linear module 16 from being parallel to the multi-layer seedling tray frame 12 to being perpendicular to the multi-layer seedling tray frame 12. Through the linear module 16 and the cross module 13, the second slider 14 is positioned at the target seedling pot layer height. The cooperation of the letter module 13 enables the electric gripper 17 on the straight module 16 to be precisely positioned above the target seedling pot on the multi-layer seedling tray frame 12 in the horizontal plane. Then, the electric gripper 17 is driven to descend vertically and grab the seedling pot. After grabbing, the seedling pot is moved to the top of the guide tube 18 through the cooperation of the straight module 16 and the cross module 13. The electric gripper 17 releases the seedling, and the seedling pot slides down the guide tube 18. When the seedling pot slides down to the bottom of the guide tube 18, the micro motors 19 on both sides drive the duckbill clip 20 to open the duckbill clip 20 and insert the seedling pot into the hole. Finally, the electric push rod 2101 pushes the connecting rod 2102 to operate the two connecting frames 2103 to rotate, so that the soil covering and compacting wheel 22 covers and compacts the soil on both sides of the planted seedling at a suitable angle and pressure, completing the entire transplanting operation.

[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
