Description

Technical Field

[0001] This utility model relates to the field of transplanter technology, specifically to a vegetable planting transplanter. Background Technology

[0002] With the continuous improvement of modern agricultural mechanization, vegetable transplanters, as important equipment for automating the process from seedling cultivation to field planting, have received widespread attention and application. Traditional vegetable transplanters replace manual labor in planting seedlings through mechanization, significantly improving planting efficiency, reducing labor intensity, and promoting the modernization of agricultural production. Especially against the backdrop of increasingly widespread large-scale planting and refined management, the performance and operational efficiency of vegetable transplanters have become important indicators for measuring the level of agricultural mechanization.

[0003] However, most existing vegetable transplanting machines still have many shortcomings in practical applications. Typically, these machines require operators to manually remove seedlings from the placement tray and place them into the feeding pipe, after which the machine completes the seedling transport and implantation. This semi-automated operation not only increases manual labor, leading to high labor intensity, but also introduces instability and low efficiency due to human factors. Furthermore, the intermittent nature of manual operation restricts the smoothness of continuous mechanical operation and overall production efficiency, making it difficult to meet the demands of modern agriculture for efficient, precise, and automated production.

[0004] Therefore, this solution proposes a vegetable planting and transplanting machine to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a vegetable planting and transplanting machine.

[0006] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: A vegetable planting and transplanting machine includes a frame and a transplanting box installed at its front end. Several feeding pipes are equidistantly arranged on the top of the transplanting box. A side rotating disc is rotatably installed on both the left and right sides of the rear of the frame. Ten seedling placement trays are evenly installed along the circumference between the two side rotating discs. A motor is also installed on the rear side of the frame to drive the side rotating discs to rotate intermittently at a specific angle. Seedling clamping components are arranged at the front end of the frame, directly above the feeding pipes and in front of the foremost seedling placement tray. A material picking drive component that cooperates with the seedling clamping components is installed on the top of the transplanting box.

[0007] Preferably, each seedling tray has several inclined guide grooves that are equidistant from front to back, and several seedlings with soil are placed in each inclined guide groove from front to back.

[0008] Preferably, a counterweight is installed at the bottom of each seedling tray.

[0009] Preferably, the seedling clamping component includes a fixed beam, grippers, and a clamping drive component. Several grippers are equidistantly distributed laterally at the bottom of the fixed beam, and the clamping drive component is mounted on the fixed beam.

[0010] The gripper includes a fixed base, gripping arms, and arc-shaped protrusions. The fixed base is fixed to the bottom of the fixed beam. Four gripping arms are evenly installed on the bottom of the fixed base along its circumference. Four arc-shaped protrusions are correspondingly distributed at the center position of the outer side of each gripping arm.

[0011] Preferably, the clamping drive component includes a drive ring, a U-shaped connecting frame, a fixed frame, and a stepping cylinder. The number of drive rings is the same as the number of grippers. Each drive ring is sleeved on the outside of four gripping arms and located below four arc-shaped protrusions. The U-shaped connecting frame connects each drive ring, and its left and right ends slide through the inside of both ends of the fixed beam. The fixed frame is located directly above the fixed beam and connected to the top of both ends of the U-shaped connecting frame. The bottom end of the stepping cylinder housing is fixed at the center position of the fixed beam, and the rod end of the stepping cylinder is abutted at the center position of the fixed frame.

[0012] Preferably, the material handling drive includes a rotary cylinder, a first swing arm, a second swing arm, a connecting rod, and a fixed plate. The fixed plate is installed on the left and right sides above the transplanting box. The rotary cylinder is installed at the center of the left fixed plate. The connecting rod is vertically distributed and its bottom end is fixedly connected to the end of the fixed beam inside the seedling clamp. One end of the inner side of the first swing arm is connected to the output shaft of the rotary cylinder, and the other end is connected to the bottom end of the connecting rod through a bearing. The second swing arm is located above the first swing arm. One end of the inner side of the second swing arm is hinged to the fixed plate and located directly above the inner end of the first swing arm. The other end of the second swing arm is hinged to the top of the connecting rod.

[0013] The beneficial effects of this utility model are reflected in:

[0014] This invention achieves highly efficient and automated transplanting of vegetable seedlings through innovative structural design, significantly improving operational stability and accuracy. The use of a double-sided rotating disc and an intermittently driven seedling conveyor chain ensures orderly transport and positioning of the seedling trays, avoiding the operational interruptions and reduced efficiency caused by uneven seedling transport or positional deviations in traditional transplanters. The seedling trays are equipped with inclined guide grooves, utilizing the seedlings' own weight for natural sliding replenishment, simplifying the seedling replenishment process and reducing mechanical complexity and failure rate.

[0015] The seedling gripper features a multi-claw design combined with elastic gripping arms and an arc-shaped protrusion pressing mechanism, ensuring flexibility and reliability in the gripping action. It can adapt to seedlings of different sizes and soil conditions, reducing damage and improving survival rates. A stepping cylinder controls the opening and closing of the grippers, achieving precise synchronization between gripping and releasing the seedlings, further enhancing operational stability and repeatability. The material handling drive uses a rotary cylinder in conjunction with a swing arm linkage mechanism, converting rotational motion into a complex forward and backward composite motion trajectory, ensuring smooth and stable gripping and releasing actions.

[0016] The overall system achieves efficient linkage between seedling conveying and gripping through coordinated control of motors and cylinders, ensuring accurate timing of each action and greatly improving the automation level and production efficiency of transplanting operations. Meanwhile, the structural design emphasizes modularity and mechanical rigidity, enhancing the equipment's durability and ease of maintenance, and adapting to different operating environments and crop types.

[0017] In summary, this utility model not only automates and improves the efficiency of vegetable seedling transplanting, but also effectively ensures the stability of operations and the survival rate of seedlings through reasonable mechanical structure design and precise motion control. It significantly reduces the intensity of manual labor, improves the level of intelligent agricultural production, and has broad application value and good market prospects.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0033] Example 1:

[0034] like Figures 1 to 6 As shown, this utility model provides a vegetable transplanting machine, including a frame 1 and a transplanting box 2 fixedly installed at its front end. Several feed pipes 3 are equidistantly arranged on the top of the transplanting box 2 along its length for guiding seedlings into the interior of the transplanting box 2. Its main structure is consistent with the internal structure of conventional transplanting machines on the market.

[0035] Two side rotating disks 4 are symmetrically mounted on the left and right sides of the rear of the frame 1 via bearings or shafts. Ten seedling trays 6 are evenly fixedly connected between the two side rotating disks 4 along their circumference, forming a rotatable seedling conveyor chain. A motor 5 is mounted on the side of the rear end of the frame 1, and the output shaft of the motor 5 is connected to one of the side rotating disks 4. The motor 5 is configured to receive control signals and drive the side rotating disks 4 to rotate intermittently, with each rotation being 36 degrees (i.e., 360° / 10), so that with each rotation, a new seedling tray 6 is conveyed to the working position.

[0036] At the front end of the frame 1, directly above all the feeding pipes 3 and in front of the seedling placement tray 6 at the foremost working position, there is a set of seedling clamping components 7. A set of material picking drive components 8 is installed on the top of the transplanting box 2. This drive component is used to drive the seedling clamping components 7 to complete the combined movement of picking up and placing seedlings.

[0037] Each seedling tray 6 has several forward-sloping and downward-sloping guide grooves 61 inside. These guide grooves are used to accommodate and guide the seedlings with soil attached, so that after the seedlings in the previous row are taken out, they can slide to the front by their own weight under the influence of the guide grooves 61 to wait for the clamping operation.

[0038] To increase the stability of the entire rotating mechanism and prevent it from remaining horizontal while rotating with the side disc 4, a counterweight 6 is installed at the bottom of each seedling placement tray 6.

[0039] Example 2:

[0040] Based on Example 1, this example refines the seedling clamping component 7 and the material handling drive component 8.

[0041] The seedling clamping component 7 includes a horizontal fixed beam 71, several grippers 72, and a clamping and placing drive unit 73. The fixed beam 71 is horizontally positioned, and the grippers 72 are distributed horizontally at equal intervals and fixedly installed at the bottom of the fixed beam 71, with their number and spacing corresponding to the feed pipe 3. The clamping and placing drive unit 73 is installed on the fixed beam 71 and is used to synchronously control the opening and closing of all grippers 72.

[0042] Each gripper 72 includes a fixed base 721, four gripping arms 722, and four arc-shaped protrusions 723. The upper end of the fixed base 721 is fixedly connected to the bottom of the fixed beam 71. The four gripping arms 722 are arranged vertically, and their upper ends are circumferentially and evenly fixed to the bottom of the fixed base 721. The gripping arms 722 are made of elastic metal, allowing their lower ends to open outward or retract inward. The four arc-shaped protrusions 723 are respectively fixedly installed at the center position of the outer side wall of each gripping arm 722.

[0043] The clamping drive component 73 includes a drive ring 731, a U-shaped connecting frame 732, a fixing frame 733, and a stepping cylinder 734. The number of drive rings 731 matches the number of grippers 72. Each drive ring 731 is sleeved on the outside of the four gripping arms 722 of the corresponding gripper 72 and located below the four arc-shaped protrusions 723. When the drive ring 731 rises, it squeezes the four arc-shaped protrusions 723, thereby causing the bottom ends of the four gripping arms 722 to retract, achieving the clamping operation. The two sides of the U-shaped connecting frame 732 are fixedly connected to the two sides of all the drive rings 731, and its left and right ends slide through the guide holes at both ends of the fixing beam 71, allowing it to slide up and down. The fixing frame 733 is located directly above the fixing beam 71, and its two ends are fixedly connected to the top ends of the U-shaped connecting frame 732. The bottom of the cylinder body of the stepping cylinder 734 is fixed to the center position of the fixing beam 71, and the top end of its piston rod is aligned with the center position of the fixing frame 733.

[0044] When the piston rod of the stepping cylinder 734 extends, it pushes the fixed frame 733 and the U-shaped connecting frame 732 upward. The U-shaped connecting frame 732 drives all the drive rings 731 to move upward synchronously. During the upward movement, the inner wall of the drive ring 731 squeezes the arc-shaped protrusion 723 on the clamping arm 722. Since the protrusion is an arc-shaped inclined surface and the middle of the clamping arm 722 is the force point, this squeezing force forces the lower ends of the four clamping arms 722 to retract inward, thereby achieving the clamping action. When the piston rod retracts, the drive ring 731 moves downward, the pressure on the arc-shaped protrusion 723 is released, and the clamping arm 722 automatically springs back to the open state under its own elasticity, completing the seedling release.

[0045] The material handling drive unit 8 includes a rotary cylinder 81, a first swing arm 82, a second swing arm 83, a connecting rod 84, and a fixed plate 85. The two fixed plates 85 are respectively fixedly installed on the left and right sides above the transplanting box 2 via brackets. The rotary cylinder 81 (whose rotation angle is set between -180° and 0° and performs intermittent reciprocating rotation) is installed at the center of the left fixed plate 85. The connecting rod 84 is vertically arranged, and its bottom end is fixedly connected to the end of the fixed beam 71 in the seedling clamping component 7. One inner end of the first swing arm 82 is directly fixedly connected to the output shaft of the rotary cylinder 81, and its other outer end is connected to the bottom end of the connecting rod 84 via a bearing or hinge. The second swing arm 83 is located above the first swing arm 82, and its inner end is hinged to the fixed plate 85 via a pin, with this hinge point located directly above the output shaft of the rotary cylinder 81 (i.e., the inner end of the first swing arm 82). The other end of the outer side of the second swing arm 83 is connected to the top of the connecting rod 84 via a bearing or hinge.

[0046] When the rotary cylinder 81 starts, it drives the first swing arm 82 to perform circular motion. Due to the constraint of the second swing arm 83, the rotation of the first swing arm 82 is converted into a specific motion trajectory of the connecting rod 84, thereby enabling the entire seedling clamping component 7 to perform the operations of picking up and placing seedlings. By reasonably designing the lengths of the first swing arm 82 and the second swing arm 83, the motion path of the end of the connecting rod 84 can be controlled. This path is designed as follows: first, it moves obliquely forward and downward from the seedling placement tray 6 at the rear to the seedling picking point, where the gripper 72 picks up the seedling; then it is lifted and moves horizontally forward to directly above the feeding pipe 3; finally, it moves downward to put the seedling into the feeding pipe 3. After completion, it returns along the original trajectory to perform the next seedling picking. The rotary cylinder 81 and the motor 5 work in coordination through the control system to ensure that the seedling placement tray 6 has intermittently rotated to the correct position and is in a stationary state when picking up seedlings.

[0047] Working principle:

[0048] During operation, motor 5 intermittently drives the side rotary disk 4 to rotate, sequentially conveying the seedling tray 6 filled with seedlings to the foremost working position. Simultaneously, the rotary cylinder 81 of the material-picking drive 8 operates continuously, driving the seedling clamping component 7 along a predetermined trajectory via a swing arm mechanism. When it reaches the front of the inclined guide groove 61 of the seedling tray 6, the stepping cylinder 734 of the clamping drive 73 actuates, causing the grippers 72 to open and insert between the seedlings and soil. Then, the cylinder reverses its action, closing the grippers 72 and clamping several seedlings at the foremost position. Subsequently, the material-picking drive 8 moves the clamped seedlings to directly above the feed pipe 3 of the transplanting box 2. The stepping cylinder 734 actuates again, opening the grippers 72, and the seedlings fall into the feed pipe 3 under gravity, ultimately being planted in the soil. This cycle repeats continuously, achieving efficient and automated vegetable seedling transplanting operations.
