Description

Technical Field

[0001] This invention relates to a combined harvester for both stems and leaves of Artemisia argyi, belonging to the field of agricultural harvesting machinery and equipment. Background Technology

[0002] Artemisia argyi is a traditional, high-quality medicinal herb in my country. It is a perennial herb or slightly shrubby plant belonging to the Artemisia genus of the Asteraceae family. Both the leaves and stems of Artemisia argyi can be used medicinally, and it is widely used for warming the meridians, dispelling dampness, dispelling cold, stopping bleeding, reducing inflammation, relieving asthma, and stopping coughs. It has extremely high medicinal value.

[0003] With the continuous expansion of the Artemisia argyi industry, the area of ​​large-scale Artemisia argyi cultivation has increased rapidly. Currently, the machine harvesting of Artemisia argyi is mostly a two-stage harvesting process, and manual defoliation is often required, which results in problems such as long harvesting time and high labor intensity. There are few dedicated combined harvesters for Artemisia argyi, and other crop harvesters are mostly used instead, but this still fails to achieve the goal of harvesting both stems and leaves, which is not conducive to maximizing the value of Artemisia argyi and the subsequent growth of Artemisia argyi.

[0004] Therefore, a combined harvester for Artemisia argyi with both stem and leaf harvesting was designed to adapt to Artemisia argyi of different plant heights. This machine can complete the harvesting, leaf removal, and sorting and collection of Artemisia argyi leaves and stems in one operation, maximizing the value of the harvested products while saving manpower and resources, improving labor productivity, and supporting the high-quality development of the Artemisia argyi industry. Summary of the Invention

[0005] The purpose of this invention is to provide a combined harvester for Artemisia argyi with both stem and leaf harvesting, which can adapt to Artemisia argyi of different plant heights and complete the harvesting, defoliation, and classification and collection of Artemisia argyi leaves and stems in one go, thereby maximizing the value of Artemisia argyi harvest products, saving manpower and material resources, improving labor productivity, and supporting the high-quality development of the Artemisia argyi industry.

[0022] (2) The harvesting device of the present invention adopts a two-stage cutting harvesting method. The first cutting is performed by a reciprocating cutter located at the bottom of the front end of the frame to cut the stem of Artemisia argyi near the ground. The second cutting is performed after the leaves on the main stem of Artemisia argyi have been removed. The tip of Artemisia argyi is then transported to the disc cutter group at the top of the rear end of the frame by the clamping conveyor belt. The disc cutter group cuts the tip of Artemisia argyi and the tip enters the leaf collection bin. The stem after the leaves have been removed enters the stem collection box. The harvesting, leaf removal, and classification and collection of Artemisia argyi leaves and stems are completed in one go, maximizing the value of the harvested Artemisia argyi products.

[0023] (3) The present invention adopts a harvesting lifting platform to realize the lifting of the harvesting device, ensuring that the stem and leaf double harvesting artemisia can adapt to artemisia at different growth heights. Attached Figure Description

[0064] When the stem and leaf double-harvest Artemisia argyi combine harvester of the present invention operates in the Artemisia argyi field, firstly, the lifting platform drive turntable is rotated to adjust the harvesting device to a height equivalent to the tip of the Artemisia argyi; then, the harvester is started, and under the drive of the transmission system, the reciprocating cutter, the toothed roller, the clamping conveyor belt, and the disc cutter group begin to operate, and the harvester moves forward; immediately afterward, the reciprocating cutter cuts the stems of the Artemisia argyi near the ground, and at the same time, the divider divides and guides the tip of the Artemisia argyi into the clamping conveyor belt. The mugwort is clamped and conveyed backward. When it reaches the toothed roller, the leaves below the tip of the mugwort fall off in reverse due to the centrifugal force of the toothed roller. The fallen leaves are then conveyed to the mugwort leaf collection box by the conveyor auger. The mugwort continues to be conveyed backward by the conveyor belt and reaches the disc cutter group. The disc cutter cuts off the tips of the mugwort that have not yet shed leaves, and the mugwort stems fall directly into the stem collection box. The tips of the mugwort are conveyed to the end of the conveyor belt and fall into the mugwort leaf collection box through the "7"-shaped feed inlet, thus completing the double harvesting of the stems and leaves of the mugwort.
