Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a folding and unfolding device for harvesting seabuckthorn fruit branches. Background Art

[0002] Seabuckthorn is a plant with important economic and ecological value. Its fruit is rich in a variety of beneficial ingredients and is widely used in medicine, food, health products and cosmetics. At the same time, as an ecological tree species, seabuckthorn also plays an important role in soil and water conservation, desertification control and other aspects. my country has a wide range of seabuckthorn planting areas, especially in Xinjiang and other places where large-scale concentrated planting areas have been formed. Although the seabuckthorn industry has broad prospects, its picking process still relies on traditional manual operations, which is inefficient and labor-intensive. With the expansion of the scale of seabuckthorn planting, traditional manual picking can no longer meet the needs of large-scale and efficient harvesting. There is an urgent need for a mechanized equipment to improve harvesting efficiency and reduce labor costs.

[0003] At present, although there are some sea buckthorn picking machinery and equipment on the market, they generally have the problems of being too large, difficult to adapt to complex terrain and limited working space. Most of the existing equipment is suitable for single-row operation and cannot efficiently cover large areas of planting areas. In addition, the volume of the equipment during operation is too large, which makes transportation and storage inconvenient. This makes it difficult to move or transfer the equipment after field operation, which seriously limits the efficiency of the equipment. At the same time, the existing equipment lacks sufficient flexibility during the operation process, cannot freely adjust the harvesting angle and operating range, and cannot fully adapt to the needs of different sea buckthorn planting row spacing and terrain.

[0004] In order to solve the problem that the current sea buckthorn picking equipment is too large and lacks flexibility, the present invention provides an innovative folding and unfolding device. The device solves the problem of equipment transportation and operation flexibility through the coordinated movement of different mechanisms, can adapt to different sea buckthorn planting environments, improve operation efficiency and facilitate storage and transportation.

In addition, the folding and unfolding device also has a flexible adjustment function, which enables the equipment to adjust the angle and working state of the harvesting device according to changes in the sea buckthorn planting row spacing and terrain, thereby improving the adaptability and flexibility of the equipment, solving the problem that the existing equipment cannot be freely adjusted, and meeting the needs of large-scale and high-efficiency harvesting.
