Description

Technical Field

[0001] The invention belongs to the technical field of forest seedling cultivation, and in particular relates to a forest seedling cultivation and pruning device. Background Art

[0002] To ensure healthy growth and ideal tree shape during the tree nursery process, periodic pruning is required during the growing season and the winter shaping period. Currently, two main pruning methods are used in the industry: manual pruning, which requires operators to work from high altitude using tools such as pruning shears and high-branch saws; and mechanized pruning devices, which typically use an arc-shaped pruning blade assembly that moves in a circular motion around the seedling, achieving batch pruning through rotary cutting.

[0003] In the prior art (Announcement No. CN222263715U, Patent Name: A Patent Application for a Forest Seedling Pruning Device), the output end of the drive motor is rotated to drive the hydraulic rod to rotate, which in turn drives the arc-shaped pruning knife to perform circular motion around the green plant, thereby quickly pruning the crown of the green plant into a spherical shape. This ensures the neatness of the pruning, avoids uneven crowns after pruning, improves the aesthetics of the green plant, and replaces traditional manual pruning, greatly reducing the workload of workers and significantly improving pruning efficiency and quality. In the process of implementing this technical solution, it was found that the prior art has at least the following problems:

[0004] In order to maintain better growth and shaping requirements for forest seedlings, it is necessary to prune their branches during the growing season and winter. During this period, pruning is either done manually with the help of knives, or with a "one-size-fits-all" pruning method using an arc-shaped pruning knife that makes a circular motion around the green plants. The latter uses an arc-shaped pruning knife to rotate around the seedlings, which cannot effectively prune, resulting in thicker and thinner branches remaining. It is also relatively rough and simple, and cannot achieve high-precision and high-quality pruning effects on forest seedlings by the method of lifting and rotating at the same time. The remaining branches not only absorb nutrients from the mother plant, but also cause it to lose its ornamental value. Summary of the Invention

[0046] The lifting assembly also includes a base 51 fixed to the bottom of the driving gear 42, and a clamping head 52 is provided below the base 51. The bottom of the clamping head 52 is fixedly connected to a first electric push rod 53 that rotates with the fixed cover 2 and is fixedly connected to the threaded rod 54. After the first electric push rod 53 adjusts the clamping stroke between the clamping head 52 and the base 51 to the right position, the stepping motor 41 drives the threaded rod 54 to rotate through the clamping head 52 and the base 51 that are clamped in place on the driving gear 42, and the threaded rod 54 is threadedly connected to the clamping head 52 and the base 51.

[0047] The fixed cover 2 is provided with vertical slots 13 on all sides, and the lifting plate 56 is provided with arc-shaped ports that slide with the vertical slots 13 on all sides near the threaded sleeve 55, which play a role of sliding limit for the threaded sleeve 55 and the lifting plate 56.

[0048] The rotating assembly also includes a bottom of the placement seat 57 fixedly connected to a slave gear 61 that rotates with the lifting plate 56 through a fixed rod, and a main gear 62 is meshed with the outside of the slave gear 61. Four sets of brackets 67 fix one end of the four steel wires 66, and then the four steel wires 66 pulled out successively drive the main gears 62 on the four rotating rods 63 to rotate synchronously through four sets of winding wheels 64. The inner cavity of the main gear 62 is fixedly connected to the rotating rod 63, and the outer side of the rotating rod 63 is fixedly connected to the winding wheel 64.

At the same time, the redundant branches in other positions of the four tree seedlings are also exposed to the pruning area of the electric mechanical arm 46 and the electric pruning knife 47, further improving the pruning accuracy and efficiency of the tree seedlings to avoid missing areas.

[0049] like Figure 12-14As shown, during the pruning of tree seedlings, water or nutrient fertilizer cannot be injected into the roots of the tree seedlings, resulting in its single function. It is necessary to add water and fertilizer separately, which is more troublesome. The transposition component is provided with a titration component used in conjunction with the liquid storage pot 3 on all four sides, and the titration component includes a differential gear 71 rotating at the four corners of the fixed cover 2, and the bottom of the differential gear 71 is fixedly connected to a second electric push rod 72 that rotates with the fixed cover 2. The four second electric push rods 72 first adjust the meshing stroke between the four sets of differential gears 71 and the double-sided gear ring 44 to the right position, and the bottom of the second electric push rod 72 is fixedly connected to a stirring blade 73 that rotates with the liquid storage pot 3, and the bottom of the stirring blade 73 is fixedly connected to a disrupting blade 74, and the bottom of the disrupting blade 74 is connected to a burette 76 with an electric control valve 75. The burette 76 adopts a hose design, and the bottom end of the burette 76 is connected to There is a titration head 77 embedded in the fixed frame 1 and with a pinch ear, and a quantitative sensor 17 is embedded on the electric control valve 75. Before this, the titration heads 77 on the four titration tubes 76 are pulled out from the fixed frame 1 and inserted into the root soil of the four tree seedlings in the four groups of placement seats 57, and then the double-sided gear ring 44 drives the stirring blades 73 and the disturbing blades 74 on the four second electric push rods 72 through the four groups of differential gears 71 engaged in place to stir and prepare the liquid nutrient fertilizer in the four groups of liquid storage pots 3, and with the auxiliary pressure cooperation of the disturbing blades 74, after quantitative detection is carried out by the quantitative sensor 17 on the opened four groups of electric control valves 75, the titration heads 77 on the four titration tubes 76 inject a quantitative amount of nutrient fertilizer into the root soil of the four tree seedlings, thereby achieving the effect of injecting water and nutrient fertilizer, which not only saves time and effort, but also is beneficial to the growth of the tree seedlings after pruning.

[0050] The working principle of a forest seedling pruning device is as follows: first, four forest seedlings to be pruned are placed in four groups of placement seats 57 on the lifting plate 56, and the titration heads 77 on the four burettes 76 are inserted into the soil at the roots of the four forest seedlings in the four groups of placement seats 57, first, the four second electric push rods 72 are controlled to drive the four groups of differential gears 71 to move up and be stuck to the outer meshing part of the double-sided gear ring 44, and then the stepping motor 41 is controlled to start and drive the driving gear 42 to rotate, the driving gear 42 drives the four groups of planetary gears 43 to rotate accordingly, the four groups of planetary gears 43 drive the double-sided gear ring 44 to rotate linearly, and the linearly rotating double-sided gear ring 44 drives the four groups of differential gears 71 engaged in place to rotate differentially, and the four groups of differential gears 71 drive the four stirring blades 73 and the spoiler blades 74 to rotate in the four groups of liquid storage pots 3, and lift them. The nutrient solution and nutrient fertilizer added before are mixed evenly, and with the auxiliary pressure cooperation of the four spoiler blades 74, the liquid nutrient fertilizer prepared in the four groups of liquid storage pots 3 is quantitatively regulated by the quantitative sensors 17 on the four groups of electric control valves 75 in the open state, and the liquid nutrient fertilizer is then quantitatively delivered to the root soil of the four tree seedlings by the burette heads 77 on the four burettes 76. During this period, the double-sided gear ring 44 drives the electric mechanical arm 46 and the electric pruning knife 47 to rotate linearly around the four tree seedlings through the slide 45, and the four tree seedlings are pre-detected by the industrial camera 11. After the roots of the four tree seedlings are nutrient-filled, the stepper motor 41 is first controlled to pause, and then the four second electric push rods 72 are controlled to close and drive the four groups of differential gears 71 to move down and disengage from the outer meshing part of the double-sided gear ring 44 to the initial position;

[0051] Next, the stepper motor 41 is controlled to start again and the double-sided gear ring 44 on the four sets of planetary gears 43 is driven to rotate linearly through the driving gear 42. The double-sided gear ring 44 drives the electric mechanical arm 46 and the electric pruning knife 47 to rotate linearly around the four tree seedlings through the slide 45 to trim the redundant branches in the outer area of the four tree seedlings. After the redundant branches in the outer area of the four tree seedlings are trimmed, the stepper motor 41 is controlled to pause first, and then the first electric push rod 53 is controlled to start and drive the clamping head 52 to move up and be clamped in the clamping seat 51. Then the stepper motor 41 is controlled to start again and the clamping seat 51 and the clamping head 52 that are clamped in place are driven by the threaded rod 54 to rotate forward. The threaded rod 54 drives the lifting plate 56 on the threaded sleeve 55 to move upward. The lifting plate 56 drives the four tree seedlings in the four sets of placement seats 57 to move upward. One end of the wire rope 66 is fixed, and as the four tree seedlings in the four groups of placement seats 57 continue to move upward, the four wire ropes 66 are pulled up by the lifting plate 56. As the four wire ropes 66 are pulled up, the four wire ropes 66 with shortened lengths also drive the four groups of winding wheels 64 to rotate accordingly. The four groups of winding wheels 64 drive the four groups of main gears 62 to rotate through the four rotating rods 63, and the four groups of springs 65 reversely tighten the four rotating rods 63. Then the four groups of main gears 62 drive the placement seats 57 on the four groups of slave gears 61 to rotate in the lifting plate 56, and drive the four tree seedlings therein to move up and rotate at the same time, and use the industrial camera 11 to shoot the pruning picture, and with the help of the displacement sensor 12 to locate the arrival position, the branches on the other side of the four tree seedlings are exposed to the pruning area of the electric mechanical arm 46 and the electric pruning knife 47, and their excess branches are trimmed.

[0052] It should be noted that the specific models and specifications of the stepper motor 41, electric robotic arm 46, electric trimming knife 47, electric push rod, industrial camera 11 and various sensors and valves need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0053] The power supply circuits of the stepping motor 41 , the electric robotic arm 46 , the electric trimming knife 47 , the electric push rod, the industrial camera 11 , and various sensors and valves are clear to those skilled in the art and will not be described in detail here.
