Description

Technical Field

[0001] This utility model belongs to the technical field of leaf cutter, specifically relating to a pineapple leaf cutter. Background Technology

[0002] Pineapple is a perennial herbaceous plant belonging to the genus Ananas in the family Bromeliaceae. The leaves of the pineapple grow in a rosette shape, with the base tightly wrapped to form a "water cup" structure, which can collect rainwater for the plant to use. The leaves are narrow and sword-like, usually 30-90 cm long and 3-5 cm wide, with fine serrations on the edges and sharp tips.

[0003] While the unique sword-shaped structure of pineapple leaves gives them strong ecological adaptability, the densely packed sharp serrations along their edges also pose a safety hazard in the production process. Because the leaf tips of some varieties (such as traditional thorny-leaf varieties) are as hard as fine needles, and the serrations along the leaf edges are hooked, manual harvesting remains the mainstream method in production areas where mechanized harvesting technology is not yet fully widespread. However, even with double-layered protective gloves, harvesters still face the risk of being scratched by the leaves, especially during the rainy season when the leaves have high water content and increased toughness, significantly reducing harvesting efficiency. This contradiction drives up labor costs. Utility Model Content

[0004] The purpose of this invention is to provide a pineapple leaf cutting machine to solve the problems mentioned in the background art, which currently rely mainly on manual cutting operations for pineapple leaves, resulting in low work efficiency and high labor costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pineapple leaf-cutting machine, comprising a shaft with a control handle mounted at the top and a handrail (not shown in the figure) mounted on the shaft below the control handle; a horizontally arranged servo motor is mounted at the bottom of the shaft, and a cutting assembly is mounted on the output end of the servo motor, the cutting assembly comprising: a connector fixed to the output end of the servo motor; two cutting pieces, each sleeved on the connector, and the cutting pieces rotating around the axis of the connector in a vertical plane, thereby cutting pineapple leaves through the two vertical cutting pieces; an adjusting component is provided at the connection between the cutting pieces and the connector, thereby adjusting the spacing between the cutting pieces to accommodate the cutting of pineapples of different shapes.

[0006] Preferably, the connector includes a lead screw and a connector fixed to the end of the lead screw; the surface of the connector has a screw hole, the connector is sleeved on the output end of the servo motor, a bolt is screwed into the screw hole, the bolt passes through the inside of the output end of the servo motor, thereby realizing the connection between the lead screw and the output end of the servo motor, so as to achieve the purpose of driving the lead screw to rotate through the servo motor, the cutting part is sleeved on the lead screw, and the lead screw drives the cutting part to rotate at high speed, thereby realizing the cutting of pineapple leaves.

[0007] Preferably, the cutting element is a cutting blade, and the two cutting blades are parallel and rotate in a vertical plane.

[0008] Preferably, the lead screw is also screwed with multiple limiting nuts, and each cutting blade has at least one limiting nut on both sides. The limiting nuts can limit the cutting blade to ensure that the cutting blade will not loosen under high-speed rotation, and the position of the cutting blade can be adjusted by rotating the limiting nuts.

[0009] Preferably, an end plate is fixed at one end of the lead screw, and a connecting plate is formed at the connection between the lead screw and the connector. Protective components are provided between the end plate and the outermost limiting nut at one end, between the two inner limiting nuts, and between the outermost limiting nut at the other end and the connecting plate. The protective components separate the cutting debris from the lead screw, preventing the flying debris from getting stuck in the threads of the lead screw and affecting subsequent rotation.

[0010] Preferably, the protective component is a corrugated pipe, which can be made of high-strength plastic or flexible metal. Connecting rings are connected to both ends of the corrugated pipe, and double-sided adhesive is bonded to the outer end face of the connecting ring. The double-sided adhesive is bonded to the end plate, limit nut and connecting plate at the corresponding position. The installation of the corrugated pipe can be achieved by the double-sided adhesive, and the structure is simple and the connection is convenient.

[0011] Preferably, the inside of the lever is hollow, a removable rechargeable battery is installed at the rear end of the control handle, and the servo motor is connected to the power supply of the control handle via a wire, so that the servo motor can be started by the control handle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention enables automated pineapple leaf cutting, significantly reducing cutting time and improving overall production efficiency compared to manual methods. Furthermore, the device can adjust the blade spacing according to the actual width of different pineapples, perfectly adapting to both smaller, compact pineapples and larger, more expansive varieties. This ensures efficient and precise cutting, minimizing damage to the pineapple fruit and addressing the shortcomings of existing technologies. Attached Figure Description
