Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery automation, and in particular to a seedling grafting and transplanting protection device. Background Technology

[0002] In modern agricultural seedling production, seed grafting is an important technique for improving crop resistance and enhancing growth vigor. Traditional seed grafting operations rely heavily on manual labor, where technicians use knives to cut the rootstock and scion, then manually attach them and secure them with seedling clips. However, manual grafting suffers from drawbacks such as high labor intensity, low grafting efficiency, inconsistent cuts, and poor graft union, severely impacting grafting survival rates and the degree of production standardization.

[0003] In recent years, with the improvement of agricultural automation, some mechanical equipment for assisting grafting has emerged in the market, mainly including pneumatic cutting devices and robotic arm clamping systems. However, existing equipment generally suffers from the following problems: First, the clamping and positioning accuracy is not high, making it difficult to adapt to seedlings of different sizes; second, the cutting action is singular, failing to achieve precise oblique cutting at the interface; third, the seedling clamp installation process still requires manual intervention, affecting overall work efficiency; and fourth, there is a lack of integrated design, with poor linkage between various functional modules, resulting in inconvenient use and complex maintenance of the equipment.

[0004] Therefore, it is necessary to design a seedling grafting and transplanting protection device to solve the above-mentioned technical problems. Utility Model Content

[0027] like Figure 1 , Figure 3 and Figure 6As shown, it also includes an upper clamping assembly 5, which is located on top of the mounting frame I 101.

The mounting plate 52 and the pneumatic grippers III 53 are both located between two vertically arranged electric guide rails II 32, and the rotation path of the two pneumatic grippers III 53 passes below the cutting position of the cutter 47.

The protrusions for placing the baffle 61 are connected to the left and right sides of the support base 1 at the position behind the collection frame 6 by bolts. The collection frame 6 can be fixed by rotating the baffle 61. The collection frame 6 is used to collect the seedlings A that are cut off and not used for the time being. It is held by the pneumatic gripper I 34 and slid to the top of the collection frame 6 by the pneumatic gripper I 34 and then placed inside it. After rotating the baffle 61 to make it disengage from the protrusion, the collection frame 6 can be taken out.

[0029] This utility model provides a grafting and transplanting protection device for seedling A. Before use, it needs to be adapted according to the specific specifications of the seedling A to be grafted. The operator starts the electric guide rail I30 through the controller 102, which drives the mounting blocks I31 on both sides to slide up and down in the vertical direction, thereby adjusting the height position of the electric guide rail II32 and the pneumatic gripper I34 to adapt to seedlings A of different lengths. Then, the operator can install the seedling clamping roller B of the required specifications onto the feeding roller 41 and fix it by tightening the fixing bolts 42. Pull out the outer end of the seedling clamping roller B and guide it between the two rollers 48 on the rear side to ensure smooth feeding during the subsequent cutting process. Start the bidirectional motor 45 to drive the lead screws 46 on both sides to drive the cutter 47 to slide along the limiting slide groove to precisely cut the seedling clamping roller B and cut a suitable length of seedling clamp for later use.

[0030] After the above basic preparations and program debugging are completed, the operator can start the entire equipment into automatic operation through the controller 102. First, the conveyor component 2 is started. The motor I20 drives the front conveyor roller 21 to rotate, which drives the two conveyor belts I22 on both sides to rotate synchronously. The two sets of seedlings A to be grafted or placed on the conveyor belts I22 by hand or through the previous process are respectively transported to the rear end of the equipment. The two conveyor belts I22 correspond to the pneumatic grippers I34 on the left and right sides, respectively. When the seedling A reaches the designated position, the upper and lower pneumatic grippers I34 clamp the upper and lower ends of the seedling A to achieve stable clamping. Then, the pneumatic gripper II35 located between the two pneumatic grippers I34, through the inclined blades that cooperate with each other on the inner side of its gripper, performs a precise oblique cut on the middle of the seedling A in the clamped state. After the cut is completed, the pneumatic gripper II35 resets, preparing for the next round of operation. Similarly, the seedling A on the other side is also cut.

[0031] Next, the two electric guide rails II32 drive the corresponding mounting blocks II33 to move towards the center of the equipment. One side of seedling A retains the upper half, and the upper mounting block II 33 is conveyed to the conveyor belt II 24 in the middle of the equipment. The lower mounting block II 33 is conveyed to the corresponding collection boxes 6 on the left and right sides of the equipment. If the lower half of seedling A is retained, the reverse is true. When the two cut sections of seedling A are transported to the conveyor belt II 24 in the center, the mounting blocks I 31 on both sides can be driven by the electric guide rail I 30 to slide vertically over the cutting part of the mounting block II 33. Then, they continue to slide so that the cutting ends of seedling A held by the mounting blocks I 31 on both sides are at the same height. The upper and lower pneumatic grippers I 34 work together to tightly fit the cutting ends of seedling A, completing the initial docking. Then, the pneumatic gripper III 53 picks up the seedling cut off by the seedling clamping roller B. The pneumatic gripper III 53 rotates under the drive of the motor III 51 to accurately fit the seedling clamp onto the interface of seedling A, completing the final reinforcement operation. When the motor III 51 rotates, the motor in the seedling clamp assembly 4...

[0032] II49 drives the roller 48 to rotate, pushing the remaining material roller portion after shearing forward. Then, the bidirectional motor 45 starts again, driving the cutter 47 to perform the next shearing, preparing for the next clamping of seedling A.

[0033] The grafted seedlings A are transported forward by the central conveyor belt II 24 to the next process or collection area. Unused excess seedlings A or waste are transferred by the corresponding pneumatic grippers I 34 on both sides to the collection frames 6 on both sides of the support base 1 for centralized recycling. The baffle 61 and the protrusion structure can realize the quick locking and replacement of the collection frames 6, which is convenient for cleaning and maintenance.

[0034] The entire process is uniformly scheduled by controller 102, with all actuators coordinating and working together to achieve automated grafting of seedling A, improving grafting efficiency and survival rate, and is suitable for the high-efficiency and standardized grafting needs in modern agricultural seedling production.
