Abstract
Description
Technical Field
[0001] This utility model relates to the field of planting equipment technology, and in particular to a seedling-planting robot with a slow-descent device. Background Technology
[0002] During seedling transplantation, a root ball is formed around the seedling's roots, effectively reducing root damage. Furthermore, after transplanting, the root ball provides nutrients and water to the seedling for a period of time, helping it adapt to its new growing environment. Therefore, damage to the root ball should be avoided as much as possible during transplantation.
[0003] Currently, in fully automated mechanical planting, seedlings are often directly dropped into the planting pit. The soil ball at the bottom of the seedling is easily damaged by hitting the pit wall during the fall. The impact force can easily damage the root system of the seedling. At the same time, the damaged soil ball will also reduce the supply of nutrients and water to the seedling, resulting in a low survival rate. Utility Model Content
[0004] The purpose of this invention is to solve the problems in the prior art by proposing a seedling-dropping slow-descent device for a seedling planting robot, which buffers and protects the soil ball at the bottom of the seedling during transplanting, avoids damage to the seedling, and improves the survival rate of the seedling.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A seedling-dropping slow-descent device for a seedling planting robot, used to drop seedlings into planting pits, comprising:
[0007] Vehicle body;
[0008] The belt storage mechanism is located on one side of the bottom of the vehicle body;
[0009] The telescopic mechanism is located on the other side of the bottom of the vehicle body;
[0010] The deceleration belt is wound inside the storage belt mechanism and extends to the outside of the storage belt mechanism at one end;
[0011] The belt pressing mechanism is located at one end of the telescopic mechanism. The belt pressing mechanism is used to clamp one end of the deceleration belt. The telescopic mechanism can pull the belt pressing mechanism to pull out the deceleration belt and place it above the planting pit. It also includes a mounting frame, which is located at the bottom of the vehicle body. The belt storage mechanism is located on the mounting frame.
[0012] Furthermore, the belt storage mechanism includes a housing and a rotating shaft. The housing is fixedly connected to the mounting frame, and the rotating shaft is rotatably connected to the inside of the housing. One end of the deceleration belt is fixedly connected to the rotating shaft so that the rotating shaft rotates and the deceleration belt is wound onto the rotating shaft.
[0013] Furthermore, the belt storage mechanism also includes a spring, which is located at one end of the rotating shaft and is used for automatically winding the slow-descent belt.
[0014] Furthermore, the belt storage mechanism also includes a servo drive motor, the output shaft of which is fixedly connected to the rotating shaft to control the winding and unwinding of the slow-fall belt.
[0015] Furthermore, it also includes a limiting mechanism, which is mounted on the mounting frame and used to limit the slow-descent belt. The limiting mechanism includes a first roller and a second roller, the center lines of the first roller and the second roller are parallel to each other, the slow-descent belt passes between the first roller and the second roller, and the first roller has an annular limiting groove in the middle, and the slow-descent belt is located inside the annular limiting groove.
[0016] Furthermore, the telescopic mechanism is an electrically operated telescopic pole.
[0017] Furthermore, the belt pressing mechanism includes a mounting plate, a lower pressing plate, an upper pressing plate, and a driving component. The mounting plate is mounted on the telescopic mechanism. The lower pressing plate and the driving component are both fixedly connected to the mounting plate. The driving rod of the driving component is fixedly connected to the upper pressing plate to drive the upper pressing plate to press down and clamp the slow-descent belt between the lower pressing plate and the upper pressing plate.
[0018] Furthermore, the descent band is an elastic band.
[0019] The beneficial effects of this utility model are as follows:
[0020] In this invention, the seedling-dropping slow-descent device of the seedling planting robot controls the movement of the pressing belt mechanism through a telescopic mechanism. The pressing belt mechanism clamps and fixes one end of the slow-descent belt. Then, the telescopic mechanism pulls the slow-descent belt out from the storage belt mechanism and places it above the planting pit. The seedling is then placed on the slow-descent belt. When the seedling comes into contact with the elastic slow-descent belt, the descent speed of the seedling is reduced under the action of the elastic belt, so that the seedling can fall slowly into the planting pit, avoiding damage to the soil ball at the bottom of the seedling due to rapid falling and improving the survival rate of the seedling.

[0033] Reference Figure 1-7 A seedling-type plant planting robot with a slow-descent device is used to slowly lower the seedling 8 into the planting pit, avoiding damage to the soil ball at the bottom, thereby improving the survival rate of the seedling 8.
[0034] The seedling planting robot's seedling lowering device includes a vehicle body 1, a storage belt mechanism 4, a telescopic mechanism 7, a lowering belt 3, and a pressing belt mechanism 6.
[0035] The vehicle body 1 is provided with a through hole for the seedlings 8 to fall through. The mounting frame 2 is fixedly installed on one side of the through hole at the bottom of the vehicle body 1. The storage belt mechanism 4 is set on the mounting frame 2, and the telescopic mechanism 7 is installed on the other side of the through hole at the bottom of the vehicle body 1.
[0036] The tape storage mechanism 4 includes a housing 401 and a rotating shaft 403. The housing 401 is fixedly connected to the mounting bracket 2, and the rotating shaft 403 is rotatably connected to the inside of the housing 401. One end of the decelerating tape 3 is fixedly connected to the rotating shaft 403, and one end of the decelerating tape 3 extends to the outside of the tape storage mechanism 4, facilitating the clamping mechanism 6 to hold the end of the decelerating tape 3. Rotation of the rotating shaft 403 can rewind the decelerating tape 3 onto the rotating shaft 403.
[0037] In some embodiments, the belt storage mechanism 4 further includes a spring 402, which is mounted on one end of the rotating shaft 403 and is used to provide torque to automatically wind up the deceleration belt 3. The elasticity of the spring 402 can cause the rotating shaft 403 to rotate, thereby automatically winding the deceleration belt 3 onto the rotating shaft 403.
[0038] In order to improve control over the descent zone 3 and facilitate the slow descent of the seedlings on the descent zone 3;
[0039] In some embodiments, the storage belt mechanism 4 is equipped with a servo drive motor, and the rotating shaft 403 is connected to the output shaft of the servo drive motor. The servo drive motor can cause the slow-fall belt 3 to be wound up or unwound, thereby facilitating the control of the slow-falling seedlings 8 on the slow-fall belt 3 to fall slowly.
[0040] In some embodiments, the descent buffer 3 is an elastic band. When the seedling 8 comes into contact with the elastic band, the descent speed of the seedling 8 is reduced by the action of the elastic band, so as to prevent the soil ball of the seedling 8 from being damaged by strong impact.
[0041] The belt pressing mechanism 6 is located at one end of the telescopic mechanism 7. The belt pressing mechanism 6 includes a mounting plate 601, a lower pressing plate 602, an upper pressing plate 603, and a driving component 604. The mounting plate 601 is mounted on the telescopic mechanism 7. The lower pressing plate 602 and the driving component 604 are both fixedly connected to the mounting plate 601. The driving rod of the driving component 604 is fixedly connected to the upper pressing plate 603. The driving component 604 can drive the upper pressing plate 603 to press down, clamping the slow-descent belt 3 between the lower pressing plate 602 and the upper pressing plate 603.
[0042] In some embodiments, the top of the lower pressure plate 602 and the bottom of the upper pressure plate 603 are provided with protruding clamping blocks to increase the friction of the clamping surface and facilitate the stable clamping and fixing of the end of the descent belt 3.
[0043] In some embodiments, the telescopic mechanism 7 is an electrically operated telescopic rod. The electrically operated telescopic rod can drive the pressing mechanism 6 to move, thereby pulling the deceleration belt 3 out from the inside of the storage mechanism 4, so that the deceleration belt 3 is positioned above the planting pit.
[0044] In some embodiments, the drive element 604 is an electric actuator.
[0045] To improve the stability of the pull-out of the descent belt 3 and prevent its displacement;
[0046] In some embodiments, the seedling planting robot's slow-descent device further includes a limiting mechanism 5, which is mounted on the mounting frame 2 and used to limit the slow-descent belt 3. The limiting mechanism 5 includes a first roller 501 and a second roller 502, with the center lines of the first roller 501 and the second roller 502 parallel to each other. The slow-descent belt 3 passes between the first roller 501 and the second roller 502. The first roller 501 has an annular limiting groove in its middle, and the slow-descent belt 3 is located inside the annular limiting groove. The second roller 502 can press the slow-descent belt 3 into the annular limiting groove, which can limit the sides of the slow-descent belt 3, preventing it from shifting to the sides when moving. This ensures that when the slow-descent belt 3 is pulled out, it is always directly above the planting pit, facilitating the accurate falling of the seedling 8 into the planting pit.
[0047] The working principle of the seedling planting robot's slow descent device is as follows: First, the vehicle body 1 is moved above the planting pit, and the through hole on the vehicle body 1 is aligned with the planting pit.
[0048] Then, the pressing mechanism 6 is moved by the telescopic mechanism 7. The pressing mechanism 6 comes to one side of the deceleration belt 3, and the end of the deceleration belt 3 is inserted between the open lower pressure plate 602 and the upper pressure plate 603.
[0049] At this time, the upper pressure plate 603 is driven to press down by the drive component 604, clamping one end of the deceleration belt 3 between the lower pressure plate 602 and the upper pressure plate 603. Then, the belt pressing mechanism 6 is reset by the telescopic mechanism 7, and the belt pressing mechanism 6 pulls the deceleration belt 3, so that it is pulled out from the inside of the belt storage mechanism 4 and placed above the planting pit.
[0050] Next, place the seedling 8 on the slow-descent belt 3. When the seedling 8 comes into contact with the elastic slow-descent belt 3, the elastic belt reduces the descent speed of the seedling 8, allowing the seedling 8 to fall slowly into the planting pit, avoiding damage to the soil ball at the bottom of the seedling 8 due to rapid falling.
[0051] After the seedling 8 falls into the planting pit, the upper pressure plate 603 is driven to rise by the drive component 604, which loosens one end of the slow descent belt 3. At this time, the slow descent belt 3 can be wound into the storage belt mechanism 4 by the spring 402 or the servo drive motor, so that the next seedling 8 can be placed and planted.
[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
