Description

Technical Field

[0001] This utility model belongs to the field of agricultural harvesting machinery technology, specifically relating to a pineapple leaf-removing roller structure and a leaf-removing machine. Background Technology

[0002] Pineapple leaves are the waste product after pineapple harvesting. my country has abundant resources of pineapple leaves, producing approximately 10 million tons annually. The fiber extracted from them (pineapple leaf fiber) is a high-quality textile material and can also be used in papermaking or as an industrial filler. The leaf residue obtained from fiber extraction can be used to make animal feed, produce biogas and organic fertilizer, or extract chlorophyll. Currently, the Philippines and India have begun comprehensive development and utilization of pineapple leaves. my country is also conducting industrial demonstration projects for comprehensive development and utilization.

[0003] Currently, pineapple leaf harvesting is mainly done manually. During harvesting, the leaf is firmly grasped at the base with both hands, twisted along its circumference, and then torn off with downward force. Alternatively, the plant is manually cut, one hand holding the plant while the other peels off the leaves one by one. Because pineapples are densely planted, the leaves are crisscrossed and have thorns along the edges, making it very easy to injure hands, resulting in a very harsh working environment. This manual method is labor-intensive and inefficient. According to surveys, a single laborer can only harvest 400-500 kg of leaves per day. Assuming 5 tons of leaves per acre, harvesting one acre of pineapple leaves requires approximately 10-13 laborers. Especially in recent years, with the rapid pace of urbanization, the shortage of agricultural labor has increased, making the labor cost for harvesting pineapple leaves reach 120-140 yuan / ton. In order to meet the planting season, many pineapple leaves are even shredded and returned to the field before harvesting, resulting in a complete waste of pineapple leaf resources. It can be said that the lagging development of pineapple leaf harvesting machinery technology has restricted the large-scale application of pineapple leaves.

[0004] Chinese patent CN201153393Y discloses a handheld pineapple leaf cutter that uses a high-speed rotating cutting blade to cut the pineapple leaves along the roots, making it easier for manual collection. Although the harvesting efficiency is improved, it still cuts one plant at a time, which cannot be done continuously, resulting in low efficiency and difficulty in promotion. Summary of the Invention

[0005] The purpose of this utility model is to provide a pineapple leaf-removing roller structure and a leaf-removing machine, which mechanically knocks off the leaves from upright pineapple plants in the field, so as to facilitate manual collection.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: On one hand, this utility model discloses a pineapple leaf-removing blade roller structure, characterized in that: it includes a roller shaft and a swivel blade, and multiple blade holders are distributed on the outer circumference of the roller shaft, with one swivel blade connected to each blade holder; the swivel blade includes a blade handle movably connected to the blade holder and a tubular blade head fixedly connected to the blade handle.

[0007] Furthermore, a connecting hole is provided on the handle, and the swivel knife is mounted on the knife holder by a pin passing through the connecting hole.

[0008] Furthermore, the handle is a steel strip, with the front end of the steel strip embedded in the tubular cutter head and welded and fixed thereto.

[0009] On the other hand, this utility model also discloses a pineapple defoliating machine, characterized in that it includes a frame, a gearbox and a pineapple defoliating roller structure. The frame is equipped with a three-point suspension bracket for connecting to a tractor. The gearbox and the pineapple defoliating roller structure are respectively mounted on the frame. The input shaft of the gearbox is used for transmission connection with the power output shaft on the tractor, and the output shaft of the gearbox is transmission connection with the roller shaft of the pineapple defoliating roller structure.

[0010] Furthermore, the output shaft of the gearbox is connected to a drive shaft via a coupling, and a drive wheel is connected to the end of the drive shaft. One end of the roller is connected to a drive wheel, and the drive wheel and the drive wheel are connected by a belt.

[0011] Furthermore, a movable rear cover is hinged to the rear end of the frame, with the lower end of the movable rear cover 20-30cm from the ground.

[0012] Furthermore, the movable rear cover is connected to the frame via a pin.

[0013] Furthermore, the frame is also equipped with a top cover plate, a left side plate, and a right side plate.

[0014] The beneficial effects of this utility model are: when the roller shaft of the pineapple leaf-removing roller structure of this utility model rotates, it can drive the sling to rotate, thereby knocking off the leaves of the pineapple plant.

[0015] Specifically, in actual production, the pineapple leaf remover is driven forward by a tractor, which simultaneously drives the roller shaft to rotate at high speed. The rotation direction is the same as the direction of the tractor wheels. The rotating blades strike the pineapple leaves of the pineapple plant located in front of the blade roller structure, thereby causing the leaves to detach from the stem and scatter on the ground for easy manual collection; the productivity is high.

[0016] The front of the blade of this invention is tubular with a smooth, non-sharp surface, making it less likely to damage or break pineapple leaves. The knocked-off pineapple leaves meet the requirements for processing by a hemp scraping machine. Furthermore, this invention does not require high-powered tractors and has a wide range of applications. Attached Figure Description
