Description

Technical Field

[0001] The utility model relates to the technical field of bamboo shoot harvesting, in particular to an integrated harvester for harvesting, removing leaves and bundling lettuce. Background Art

[0002] In modern agricultural production, lettuce is a widely grown vegetable, and its harvesting has always been a key link in agricultural production. Traditional lettuce harvesting mainly relies on manual operation, which is not only labor-intensive and inefficient, but also costly and difficult to ensure the quality of harvesting. With the advancement of agricultural modernization, the demand for automated and intelligent agricultural machinery is growing, especially for mechanized equipment that improves harvesting efficiency and reduces labor costs.

[0003] At present, most of the lettuce harvesting equipment on the market adopts a simple cutting and leaf stripping method. During the leaf stripping process, the leaf stripping effect is poor due to the single leaf stripping mechanism and action. In addition, the existing equipment is also limited in adapting to lettuces of different growth conditions, and it is difficult to adjust to lettuces of different densities and maturity. These problems lead to a high lettuce damage rate during the harvesting process, serious waste of resources, and high equipment operation complexity and maintenance costs. In addition, most harvesting equipment is not equipped with a bundling mechanism, and the harvested lettuce cannot be effectively collected and bundled. The scattered lettuce takes up a lot of space, is not convenient for storage and transportation, increases logistics costs, and is easily damaged during transportation. Utility Model Content

[0018] The beneficial effects achieved by the utility model are:

[0019] First, the utility model realizes the automation, precision and efficiency of lettuce harvesting through the innovative design of rough peeling harvesting mechanism, transmission mechanism, fine peeling mechanism, discharging mechanism and baling mechanism. The design of this equipment takes into account the growth characteristics of crops and various needs in the harvesting process. Through the optimization of mechanical structure, it significantly improves the harvesting efficiency and reduces energy consumption, while ensuring the quality of the harvested lettuce, meeting the requirements of modern agricultural production for high efficiency, low energy consumption, high safety and low cost.

[0020] Second, the utility model divides the leaf peeling process into two stages: coarse peeling and fine peeling, which are respectively performed by specially designed mechanisms. The coarse peeling mechanism uses a double spiral knife to quickly remove the outer large leaves, while the fine peeling mechanism handles the small leaves and residual leaf veins through delicate operations, thereby realizing the specialization of tasks, reducing damage and improving the quality consistency of the final product. By peeling the leaves in stages, the lettuce is handled more gently, reducing damage to the lettuce during the coarse peeling process, especially before entering the fine peeling stage. Improve leaf peeling efficiency: coarse peeling mechanisms usually use rougher mechanical actions, while fine peeling mechanisms require more delicate operations. Separating these two processes optimizes the efficiency of each stage and avoids the adverse effects of the rough actions of the coarse peeling mechanism on the fine peeling stage. The separate leaf peeling mechanism controls the force and range of leaf peeling more accurately, thereby improving the quality of leaf peeling;

[0021] Third, the rough peeling mechanism is equipped with two rough peeling units, each of which is equipped with a spiral knife. The double spiral knives efficiently remove the large leaves outside the lettuce, laying the foundation for the subsequent fine peeling process and improving the overall leaf peeling efficiency; a synchronous belt and synchronous pulley are installed in the support seat above the spiral knife. The spiral knife is connected to the synchronous pulley through a rotating shaft and driven by a rough peeling motor. The synchronous pulley drive ensures the stable operation of the spiral knife, reduces vibration and noise during the transmission process, and improves the uniformity and reliability of leaf peeling.

[0022] Fourth, a coarse peeling spacing adjustment mechanism is provided between the two coarse peeling units, which is adjusted by a spacing adjustment motor and a screw rod. The coarse peeling spacing adjustment mechanism includes a slide rail and a slider slidably connected to the slide rail. The position of the coarse peeling unit can be precisely adjusted by the slide rail and the slider mechanism. The operation is simple and convenient, and the flexibility and accuracy of the adjustment are improved. The spacing of the coarse peeling units can be adjusted according to the different sizes of lettuces, which enhances the adaptability of the equipment and ensures the quality of leaf peeling of lettuces of different specifications. A coupling is installed under the base, and a rotating seat is rotatably connected to the bottom of the coupling, and the rotating seat is connected to the support seat of the coarse peeling unit through a connecting rod. The coarse peeling unit can be fine-tuned to adapt to lettuces of different shapes, ensuring the stability of the leaf peeling process and the integrity of the lettuce.

[0023] Fifth, the transmission mechanism includes a rough peeling conveyor belt driven by a transmission motor, and a barrier is arranged on the conveyor belt. The rough peeling conveyor belt is responsible for smoothly transmitting the roughly peeled lettuce to the next processing stage, and the barrier design helps to keep the lettuce stable during the transmission process and reduce damage.

[0024] Sixth, the clamping and conveying unit includes a front clamping and conveying unit and a rear clamping and conveying unit, which are used to stably clamp the lettuce and guide it through the fine peeling process, thereby ensuring the stability of the lettuce during the fine peeling process, reducing damage caused by unstable transmission, and improving the accuracy of fine peeling.

[0025] Seventh, the fine peeling circular knife is arranged between the front clamping and conveying unit and the rear clamping and conveying unit, and is used to finely remove the leaves of the lettuce. The design of the circular knife allows for more uniform and delicate peeling of the lettuce, thereby improving the appearance and quality of the final product. A fine peeling unit is provided, including a limit block and a telescopic shaft, and a fine peeling knife block is installed at the end of the telescopic shaft, and a spring is installed on the telescopic shaft. The telescopic design of the fine peeling unit is automatically adjusted according to the size of the lettuce, and the spring provides appropriate force to ensure the consistency of the peeling and the integrity of the lettuce. The end of the fine peeling knife block is an arc structure, and fine peeling knife teeth are installed on the arc structure. The design of the arc structure and the knife teeth helps to achieve a smooth and efficient leaf peeling action and reduce damage to the lettuce.

[0026] Eighth, the front clamping and conveying units and the rear clamping and conveying units are provided with a worm gear mechanism and a precision peeling motor to realize synchronous transmission. The synchronous transmission ensures the stability of the lettuce during the transmission process and avoids uneven peeling or damage caused by uneven speed.

[0027] Ninth, a fine peeling conveyor belt is arranged below the fine peeling ring knife, and fine peeling leaf discharge hoppers are arranged at both ends. The fine peeling conveyor belt removes the peeled leaves in time, keeps the working area clean, and improves the working efficiency.

[0028] Tenth, the baling mechanism includes a baling bin and a rotating mechanism, which can bundle the harvested lettuce. The baling mechanism is compactly designed, occupies little space, and is easy to maintain and overhaul. The baled lettuce is easy to store and transport, reducing logistics costs while protecting the lettuce from damage during transportation. The baling bin position adjustment motor adjusts the baling position as needed. The baling bin position adjustment motor allows the position of the baling bin to be precisely adjusted to accommodate lettuces of different sizes and shapes, thereby improving the flexibility and adaptability of baling. The design on both sides of the baling bin enables the equipment to adapt to the harvesting needs of lettuces with different row spacings, increasing the versatility of the equipment. The baling bins on both sides are connected by a second connecting rod, which enables the synchronous adjustment of the baling bins and ensures the consistency and reliability of the baling operation.

[0029] 11. The design of the rotating mechanism with a curved rod and a baling rotating motor makes the baling process more compact and efficient, while simplifying the mechanical structure. The other end of the curved rod is equipped with a tape, which makes the baling process smoother. At the same time, the use of the tape improves the stability and firmness of the baling. The baling channel opened in the baling bin is specifically used for winding the tape, which ensures the orderly progress of the baling process and improves the quality and efficiency of baling.

[0030] 12. The automated design of the entire baling mechanism reduces manual intervention and labor intensity, while improving operation continuity and production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
