Description

Technical Field

[0001] The invention relates to the field of seedling transplanting, and in particular to a seedling transplanting device for fruit trees and gardens. Background Art

[0002] Traditional seedling transplanting mainly relies on manual operations, including digging, handling, and planting. There are problems such as high labor intensity, low efficiency, and poor transplanting consistency. In particular, the high root damage rate directly affects the survival rate of seedlings. With the development of mechanization, semi-automatic transplanting devices have gradually been used, but most of them use general-purpose digging tools, which are difficult to adapt to the root protection needs of seedlings of different specifications. They also have complex structures and high energy consumption. In recent years, transplanting equipment based on automated control has begun to emerge, but there are still deficiencies in adaptability to complex terrain, precise positioning, and the flexibility of the clamping mechanism, resulting in frequent problems such as seedling tilting and loose soil balls. In addition, existing equipment generally lacks intelligent control modules, making it difficult to dynamically adjust transplanting parameters according to soil moisture conditions and seedling types, limiting the application effect in large-scale planting scenarios. Therefore, there is an urgent need to develop transplanting equipment that is both efficient, adaptable, and eco-friendly to improve the level of industry standardization.

[0003] In the prior art, for example, Patent Publication No. CN114424736A discloses a forest seedling cultivation device and a method of use that facilitates transplantation. The device uses an inscribed ring to keep the soil on one side of the seedling in the tree pit. Patent Publication No. CN212087372U discloses a forestry seedling transplanting device that can replace different cutting tools, effectively ensuring the integrity of the soil near the plant root system and avoiding excessive damage to the root system. Conventional transplanting processes are limited to how to remove the seedling roots from the soil at one time. Studies have shown that the root cutting process during seedling transplantation can be optimized through segmented root cutting, which can reduce the damage to the root system caused by a single root cutting, thereby extending the root repair time, making the growth recovery of the transplanted seedlings better, and improving their growth potential. Existing segmented root cutting processes all rely on manual labor, and existing transplanting devices are difficult to complete multiple-stage root cutting processes. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a device for transplanting fruit trees and garden seedlings, which can assist in the segmented root cutting and transplanting process.

[0005] In order to achieve the above-mentioned object, the technical solution of the present invention is as follows: A device for transplanting fruit trees and garden seedlings comprises a ring body, a first driving member and a pump body, wherein a plurality of soil-breaking claws are provided at the bottom of the ring body, and the first driving member is used to drive the ring body downward;

[0006] The earth-breaking claw includes a nested shell, a driving chamber is provided in the shell, and the pump body is used to inject and extract fluid into the driving chamber to control the extension and contraction of the shell;

[0007] The pump body is used to control the extension of the ground-breaking claws at the bottom of the ring body according to the number of segmented root cutting and transplanting stages when performing segmented root cutting and transplanting, and to change the position of the extended ground-breaking claws according to the execution stage of the segmented root cutting and transplanting.

[0008] The above scheme has the following beneficial effects:

[0009] 1. This solution is used to perform segmented root pruning and transplanting. Segmented root pruning is to split the original full root pruned, and the root system of the seedlings is pruned multiple times within 0-2 years. The number of root pruned times ranges from 2-4 times, and 1 / 2-1 / 4 of the root system of the seedlings is pruned each time. The seedlings are pruned and transplanted at the last root pruned time. This can reduce the damage to the root system caused by a single root pruned, thereby extending the root repair time and making the growth recovery of the transplanted seedlings better.

[0010] 2. In this solution, the user plans the number and duration of root pruning attempts, places the ring around the seedling, and sets the number and position of extended claws. After the claws are extended, the first actuator drives them into the soil, breaking the soil and severing part of the seedling's roots, completing a single stage of root pruning. In subsequent stages, as root pruning has already been completed in some locations in the previous stage, the claws in other locations are controlled to extend to complete the next stage of root pruning.

[0011] 3. In this plan, after the final stage of segmented root cutting is completed, the roots along a circle of the seedlings are completely broken and transplanting can be carried out.

[0012] Furthermore, the ring body is rotatably connected to the first driving member, and the first driving member is provided with a second driving member for driving the ring body to rotate.

[0013] Beneficial effect: Theoretically, in the subsequent root cutting stage, it is only necessary to change the position of the extended soil-breaking claws. However, due to the passage of a certain period of time, there may be a certain position offset during the installation of the ring body, and there may be a certain gap. At this time, the second driving member can be used to drive the ring body to rotate so that the root cutting positions of each root cutting stage can be better connected.

[0014] Furthermore, one end of the earth-breaking claw away from the ring body is inclined toward the center of the ring body, and the first driving member is also used to drive the ring body to lift up.

[0015] Beneficial effects: The soil-breaking claws can break the roots around the seedlings, but there are still roots at the bottom of the seedlings. The end of the soil-breaking claws away from the ring body is inclined toward the center of the ring body and can cut into the bottom of the seedlings, and lift the seedlings by lifting them up, making it easier to dig the seedlings out of the soil.

[0016] Furthermore, it also includes a vehicle body, and the first driving member and the pump body are both fixedly connected to the vehicle body.

[0017] Beneficial effect: The vehicle body can move the ring body, the first driving member and the pump body for flexible deployment.

[0018] Furthermore, the second driving member includes a motor, a gear is provided on the output shaft of the motor, and a tooth pattern that meshes with the gear is provided on the top of the ring body.

[0019] Beneficial effect: the motor can drive the gear to rotate, and the rotation of the gear will drive the ring body to rotate, thereby changing the position relationship of the ground-breaking claws at the bottom of the ring body.

[0020] Furthermore, a plurality of support frames are fixedly connected to both sides of the ring body, and one end of the support frame away from the ring body is rotatably connected to a soil pressing wheel, and the other end of the soil pressing wheel away from the ring body is inclined toward the direction of the soil breaking claw.

[0021] Beneficial Effects: After severing the roots of seedlings, the wounded surface of the roots is exposed, making them more susceptible to disease. The press wheel is deployed on the ring body. The user retracts the soil-breaking claws and lowers the ring body to contact the soil. The ring body is then driven to rotate, causing the press wheel to roll. Because the end of the press wheel away from the ring body is tilted toward the soil-breaking claws, as the press wheel rolls, it pushes soil on both sides of the pit created by the soil-breaking claws toward the pit, thereby covering the pit opening and reducing root exposure.

[0022] Furthermore, a water tank is provided on the vehicle body, and a syringe is provided on the water tank. The syringe is used to inject additives into the water tank, and an electric stirring paddle is provided in the water tank.

[0023] Beneficial Effects: Because the seedlings are still growing in situ after segmented root removal, they need to be watered immediately after early root removal to thoroughly irrigate the soil around the root removal site, allowing for faster recovery. The water tank can store clean water for convenient irrigation. Furthermore, additives such as growth enhancers and healing agents can be added to the clean water and stirred with an electric agitator to create a solution that promotes seedling recovery.

[0024] Furthermore, a first nozzle is provided on the vehicle body, and the nozzle is connected to the water tank through a first water pipe.

[0025] Beneficial effect: The user can use the first sprinkler head to sprinkle irrigation on the vehicle body, so as to carry out the sprinkler irrigation work conveniently.

[0026] Furthermore, a plurality of second nozzles are provided on the ring body, the spraying direction of the second nozzles is toward the soil-breaking claws, and the second nozzles are connected to the water tank through a second water pipe.

[0027] Beneficial effects: The second nozzle can spray clean water directly in the direction of the soil-breaking claws, which can effectively clean the soil-breaking claws, soften the soil at the site of the soil-breaking claws, complete watering, or allow the root wound surface to better contact with additives such as healing agents.

[0028] Furthermore, the vehicle body is a tracked vehicle.

[0029] Beneficial effect: Tracked vehicles can better adapt to mountainous environments, making it easier to operate in mountainous areas.

[0030] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0041] The following is further described in detail through specific implementation methods:

[0042] Example 1:

[0043] As attached Figures 1-6 The figure shows a device for transplanting fruit trees and garden seedlings, comprising a tracked vehicle with a drive member and a pump body 3 bolted to the vehicle. The drive member is a hydraulic cylinder, and the pump body 3 is a hydraulic pump, typically using hydraulic oil as the fluid. A ring body 1 is rotatably connected to the output shaft of the drive member. The bottom of the ring body 1 is provided with a plurality of ground-breaking claws 4. A first drive member 2 is used to drive the ring body 1 downward.

[0044] The ring body 1 is rotationally connected to a first drive member 2. A second drive member 5, which is bolted to the first drive member 2 and drives the ring body 1 in rotation, is bolted to the first drive member 2. The second drive member 5 comprises a motor with a gear 7 bolted to its output shaft. The top of the ring body 1 is provided with teeth 8 that mesh with the gear 7. Because the hydraulic pump transports hydraulic oil through a pipeline, which constrains the rotation angle of the ring body 1, the second drive member 5 is driven to drive the ring body 1 in a reciprocating rotation within a certain angle.

[0045] One end of the ground-breaking claw 4 away from the ring body 1 is inclined toward the center of the ring body 1 , and the first driving member 2 is also used to drive the ring body 1 to lift up.

[0046] Several support frames 9 are fixed with bolts on both sides of the ring body 1. The end of the support frame 9 away from the ring body 1 is rotatably connected to the soil pressing wheel 10, and the end of the soil pressing wheel 10 away from the ring body 1 is inclined toward the soil breaking claw 4.

[0047] Segmented root pruning is to split the original full root pruned, and sever the root system of the seedlings multiple times within 0-2 years. The number of root pruned times ranges from 2-4 times, and each time 1 / 2-1 / 4 of the root system of the seedlings is severed. The seedlings are pruned and transplanted during the last root pruned. This can reduce the damage to the root system caused by a single root pruned, thereby extending the root system's repair time and making the transplanted seedlings grow and recover better. Studies have shown that multiple root pruned times are more beneficial to the crown width of full-crown transplanted seedlings than single root pruned times. This is especially true for seedlings that are rooted during the growth period. In particular, within one year after transplantation, the growth potential has increased significantly.

[0048] The user can complete segmented root removal with the help of the soil-breaking claws 4. First, the user needs to plan the number and time of root removal. This embodiment adopts three segmentation, dividing the area around the seedling into three equal parts, removing one-third of the roots during the first year of vigorous growth, one-third of the roots after the leaves fall in the first year, and one-third of the roots during the vigorous growth period of the second year.

[0049] When rooting during the first year of vigorous growth, drive a crawler vehicle to the seedlings, place the ring body 1 on the seedlings, and lower it to near the ground. Select one-third of the soil-breaking claws 4, control the pump body 3 to pump hydraulic oil into the driving chamber of the soil-breaking claws 4, and the soil-breaking claws 4 will be pressed into the soil, breaking the soil and cutting off part of the seedling roots. Then, the hydraulic oil in the soil-breaking claws 4 will be pumped out and the soil-breaking claws 4 will be retracted. Continue to lower the ring body 1 so that the soil-breaking wheel 10 contacts the soil. The second drive member 5 drives the ring body 1 to rotate, causing the soil-breaking wheel 10 to roll. The second drive member 5 includes a motor that can drive the gear 7 to rotate. The rotation of the gear 7 will drive the ring body 1 to rotate, thereby changing the position relationship of the soil-breaking claws 4 at the bottom of the ring body 1. Because the end of the pressing wheel 10 away from the ring body 1 is tilted toward the soil-breaking claws 4, as the pressing wheel 10 rolls, it pushes the soil on both sides of the hole created by the soil-breaking claws 4 toward the hole, thereby covering the hole opening and reducing the exposure of the root system. This completes the first stage of root removal. The ring body 1 is then lifted and separated from the seedlings, awaiting the second stage.

[0050] The first stage of root pruning will repair itself before the second stage arrives to alleviate the damage caused by root pruned.

[0051] After the leaves fall in the first year, the second stage of root pruning is carried out. The crawler vehicle is driven to the seedlings, and the ring body 1 is placed on the seedlings and lowered to near the ground. The traces of the first root pruning on the ground are observed, and one-third of the soil-breaking claws 4 are selected. The second driving member 5 is controlled to drive the ring body 1 to rotate so that the selected soil-breaking claws 4 are staggered from the traces of the first root pruning and are as close to the traces of the first root pruning as possible. The pump body 3 is controlled to pump hydraulic oil into the driving cavity of the soil-breaking claws 4. The soil-breaking claws 4 will be pressed into the soil, breaking the soil and cutting off part of the root system of the seedlings. The hydraulic oil in the soil-breaking claws 4 is then pumped out, and the soil-breaking claws 4 are retracted. The soil-pressing operation of the soil-pressing wheel 10 is then repeated. The ring body 1 is lifted up and separated from the seedlings, waiting for the arrival of the third stage.

[0052] The roots in the second stage will repair themselves before the third stage arrives to alleviate the damage caused by the root pruning.

[0053] The third stage of root removal occurs during the next year's peak growth period. The crawler vehicle is driven to the seedlings, and the ring body 1 is placed over them and lowered to near the ground. Without selecting the breaking claws 4, all are pressed into the ground and extended until they are sufficient to sever the majority of the roots at the base of the seedlings. Without retracting the breaking claws 4, the first drive member 2 drives the ring body 1 upward, freeing the seedlings and the soil surrounding their roots from the ground. The freed seedlings can then be transplanted.

[0054] The soil-breaking claws 4 can break the roots around the seedlings, but there are still roots at the bottom of the seedlings. The end of the soil-breaking claws 4 away from the ring body 1 is inclined toward the center of the ring body 1 and can cut into the bottom of the seedlings and lift the seedlings by lifting them up, making it easier to dig the seedlings out of the soil.

[0055] Example 2:

[0056] The difference from the above embodiment is that a water tank 11 is bolted to the vehicle body 6, and a syringe 12 is installed on the water tank 11 for injecting additives into the water tank. An electric stirring paddle 13 is installed in the water tank 11. A first nozzle 14 is provided on the vehicle body 6, and the nozzle is connected to the water tank 11 through a first water pipe.

[0057] Because the seedlings are still growing in situ before being transplanted, it is necessary to replenish water promptly after early root removal to thoroughly water the soil at the root-cut site to help the seedlings recover faster. The water tank 11 can store clean water for convenient irrigation. In addition, additives such as growth agents and healing agents can be added to the clean water and stirred and mixed by the electric stirring paddle 13 to prepare a solution to promote seedling recovery.

[0058] The user can use the first nozzle 14 on the vehicle body 6 for sprinkler irrigation to conveniently carry out sprinkler irrigation work. Since the first nozzle 14 is on the vehicle body 6, it can be directly controlled by the user, and the first nozzle 14 can be controlled more accurately to irrigate the root-cutting part.

[0059] Example 3:

[0060] The difference from the above embodiment is that a plurality of second nozzles 15 are provided on the ring body 1 , the spraying direction of the second nozzles 15 is toward the soil-breaking claws 4 , and the second nozzles 15 are connected to the water tank 11 through a second water pipe.

[0061] The second nozzle 15 can spray clean water directly toward the soil-breaking claws 4, which can effectively clean the soil-breaking claws 4, soften the soil at the soil-breaking claws 4, complete watering, or allow the root wound surface to better contact with additives such as healing agents.

[0062] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
