Description

Technical Field

[0001] This invention relates to the field of harvesting technology, specifically a portable harvesting device. Background Technology

[0002] Currently, in agricultural, horticultural, or small-scale field crop harvesting operations, commonly used equipment is mainly divided into two categories: large combine harvesters and small handheld harvesting tools. Large combine harvesters are highly efficient, but they are bulky, expensive, and have a large turning radius, making them only suitable for open, large-area farmland. They are difficult to use flexibly in special terrains and scenarios such as hills, terraces, small plots, or greenhouses. Traditional small handheld harvesting tools (such as sickles and handheld lawnmowers) are highly flexible, but they suffer from high labor intensity, low operating efficiency, fixed harvesting width, and operator fatigue. Especially in situations where the cutting width needs to be adjusted according to crop row spacing or harvesting requirements, existing equipment often lacks a convenient and effective adjustment mechanism.

[0003] Furthermore, existing portable harvesting equipment has shortcomings in terms of storage and transportation when not in use. Many devices have fixed structures, occupy a lot of space, and are inconvenient to carry or store. At the same time, adjusting the harvesting height usually relies on overall lifting equipment or simple manual adjustment, which is not precise or convenient enough to adapt to different crop heights or uneven ground.

[0004] Therefore, there is an urgent need for a miniaturized harvesting device that is lightweight, flexible, adjustable, and highly efficient, adaptable to diverse operating scenarios, and easy to store and transport. Summary of the Invention

[0017] The present invention has the following advantages:

[0018] 1. Flexible and adjustable harvesting width with strong adaptability: By controlling the synchronous deflection of the two synchronous deflection frame mechanisms through the first drive mechanism, the distance between the first harvesting mechanism and the second harvesting mechanism on both sides can be continuously and accurately adjusted, thereby adapting to different crop row spacing or harvesting width requirements, significantly improving the equipment's adaptability to different operating scenarios.

[0019] 2. Foldable structure, excellent portability: The synchronous deflection frame mechanism not only adjusts the cutting spacing but also serves as a folding joint for the main body of the equipment.

[0021] 4. Convenient and Adjustable Harvesting Height: The unique linkage lifting wheel mechanism mechanically links the posture change of the deflection frame with the height adjustment of the support wheels. When adjusting the equipment's unfolded state or encountering uneven ground, this mechanism can automatically or with the assistance of a linear motor adjust the ground clearance of the equipment chassis, thereby indirectly or directly adjusting the working height of the harvesting mechanism to maintain a suitable cutting position at all times. It is convenient to operate and highly intelligent.

[0022] 5. Flexible operation and excellent ergonomics: The equipment is equipped with a handle and controller, allowing operators to easily push and control the equipment's movement, harvesting width adjustment, height adjustment, and power start / stop, reducing labor intensity and improving the operating experience.

[0023] 6. Sturdy structure and convenient adjustment: The components are connected by rigid transmission components such as gears, bevel gears, and shafts, ensuring reliable transmission. Key adjustment parts, such as the position plate, are fixed with locking bolts, allowing for easy adjustment of the position of the second harvesting mechanism on the mounting slot as needed, further increasing layout flexibility.

[0043] The fixed base 1 is equipped with a storage battery, which is used to power multiple motors.

[0044] In an embodiment of the present invention, the workflow is as follows:

[0045] Step 1: Equipment Status Transition and Initial Deployment

[0046] Transport status lifted: will be in Figure 5 The device, in its folded and stowed state, is pushed to the work site. At this time, the two deflection frames 204 are close to both sides of the fixed base shell 1, the overall width is at its minimum, the chassis is supported by the rear wheel 904 and the front wheel 909, and the ground clearance is low.

[0047] The unfolding procedure is initiated by issuing an unfolding command via the controller 11 on the handle 10. The first motor 301 of the first drive mechanism 3 starts, driving the second gear 302 to rotate.

[0048] Synchronous deflection motion: The second gear 302 drives the right first gear 203, which meshes with it, to rotate. Since the left first gear 203 and the right first gear 203 mesh with each other, they rotate synchronously in opposite directions. Each first gear 203 drives the rotating sleeve 202 fixed with it to rotate on the first deflection seat 201, thereby driving the two left and right deflection frames 204 to unfold outward synchronously like wings.

[0049] Step 2: Precise setting and adjustment of operating parameters

[0050] Infinitely adjustable width setting: Observe the crop row spacing or determine the required harvesting width. The controller 11 precisely controls the operation of the first motor 301 (jogging or continuous), causing the deflection frame 204 to continue expanding or slightly retract until the lateral distance between the first harvesting mechanism 7 mounted on the end of the first rotating shaft 402 and the second harvesting mechanism 8 mounted on the outermost displacement rotating mechanism 6 perfectly meets the requirements. The symmetrical movement of the two deflection frames 204 ensures that the cutting centerline remains unchanged.

[0051] Personalized Auxiliary Blade Position Layout: The positions of one or more second harvesting mechanisms 8 can be independently adjusted based on the local crop density or special boundary shapes in the field. Specifically: Loosen the first locking bolt 602 on the target displacement rotating mechanism 6, allowing the displacement plate 601 to slide freely within the mounting groove 205 of the deflection frame 204. Move the displacement plate 601, along with its integral vertical plate 603, third rotating shaft 607, and second harvesting mechanism 8, to the desired position. Then, retighten the first locking bolt 602, pressing its end against the deflection frame 204, thereby firmly fixing the entire displacement rotating mechanism 6. This adjustment ensures that power is effectively transmitted through the sliding sleeve 604 and the drive groove 407-drive bar pair of the second rotating shaft 406, unaffected by positional changes.

[0052] Accurate Harvesting Height Calibration: Observe the crop stalk height or ground flatness. The linear motor 919 in the linkage lifting wheel mechanism 9 is controlled by the controller 11. The extension or retraction of the linear motor 919 push rod drives the first synchronous plate 912 connected to it to rotate around its hinge point with the fixed base shell 1. This rotation drives the second synchronous plate 914 through the fourth rotating shaft 913, which in turn pushes or pulls the second synchronous rod 917 through the cooperation of the slider groove 915 and the slider 916. The movement of the second synchronous rod 917 forces the second deflection rod 906 to swing accordingly, and ultimately precisely controls the deflection angle of the first deflection rod 902 through the aforementioned linkage system. The change in the angle of the first deflection rod 902 directly determines the final height of the axle 903 and the rear wheel 904, thereby raising and lowering the fixed base shell 1 and all harvesting mechanisms mounted on it to the most suitable cutting height.

[0053] Step 3: Power System Start-up and Synchronous Disconnection

[0054] Active power activation: After all geometric parameters are set, the second drive mechanism 5 is started via controller 11. The second motor 502 begins to rotate, and its output shaft directly drives a third gear 403 fixed to it to rotate.

[0055] Lateral synchronous power distribution: The two meshing third gears 403 ensure that the power is transmitted instantaneously and synchronously to the first rotating shafts 402 on the left and right sides, so that they rotate at the same speed and in the same direction.

[0056] Main cutting area operation: The rotating first shaft 402 directly drives the harvesting blade sleeve 701, which is fixed to its end by the second locking bolt 702, to rotate at high speed. Multiple harvesting blades 703 evenly distributed on the harvesting blade sleeve 701 form a circular cutting area to carry out the main harvesting operation on the crop directly in front of the equipment.

[0057] Extended cutting zone power transmission and operation:

[0058] The rotation of the first shaft 402 on each side is transmitted to the second shaft 405, which meshes perpendicularly with it, through the first bevel gear 404 on it, thereby changing the direction of power and driving the second shaft 406 to rotate around its own axis.

[0059] The rotation of the second rotating shaft 406 transmits power to each sliding sleeve 604 through the meshing of its axially opened drive groove 407 with the drive bar inside each sliding sleeve 604. Since the drive groove 407 is a straight groove or a spiral groove, it allows the sliding sleeve 604 to slide axially along the second rotating shaft 406 while transmitting torque, so as to adapt to the position changes of the displacement rotating mechanism 6 under different unfolding angles of the deflection frame 204.

[0060] The rotation of each sliding sleeve 604 causes the third bevel gear 605 fixed on its outer side to rotate, and the third bevel gear 605 drives the fourth bevel gear 606 that meshes with it, thereby driving the third rotating shaft 607 to rotate.

[0061] Finally, the second harvesting mechanism 8 (with the same structure as the first harvesting mechanism 7) fixed at the end of each third rotating shaft 607 begins to rotate at high speed. As a result, all the second harvesting mechanisms 8 distributed along the deflection frame 204 rotate in strict synchronization with the first harvesting mechanism 7, forming a continuous and uniform auxiliary cutting band over the expanded width.

[0062] Step 4: Movement and Continuous Operation

[0063] Equipment pushing: The operator holds the handle 10 and pushes the equipment forward smoothly.

[0064] Continuous cutting: As the equipment moves forward using the rear wheel 904 and the front wheel 909, the high-speed rotating first harvesting mechanism 7 and second harvesting mechanism 8 continuously and efficiently cut the crop stalks that enter their cutting range. The adjustable width ensures that the cutting range matches the crop rows, while the appropriate height setting ensures the consistency of the stubble.

[0065] Step 5: End of work and restoration

[0066] Stop cutting: After the field harvesting operation is completed, the second motor 502 of the second drive mechanism 5 is turned off by the controller 11. All first harvesting mechanisms 7 and second harvesting mechanisms 8 quickly stop rotating.

[0067] Start the folding process: Control the first motor 301 of the first drive mechanism 3 to reverse through the controller 11.

[0068] Synchronous retraction: The first motor 301 drives the two deflection frames 204 to retract synchronously towards the inside of the fixed bottom shell 1 through gear transmission.

[0069] Equipment storage: When the deflection frame 204 is fully retracted and tightly attached to both sides of the fixed base shell 1, the first motor 301 stops. The equipment returns to a compact folded form, making it easy to load into a transport vehicle or store in a confined space. Finally, the main power supply to the equipment can be disconnected via the controller 11 or a physical switch.
