Alfalfa layering parting harvester and harvesting method

Abstract

The invention discloses an alfalfa layering parting harvester and an alfalfa layering parting harvesting method, and belongs to the field of agricultural mechanical manufacturing. The harvester mainly comprises a self-propelled base plate, a machine frame, an upper mowing platform, an upper conveyor, a storage box, a leaf detacher, a lamina conveyor, a lower mowing platform, a modulator, a strip collector, an upper mowing platform hydraulic rod and a machine frame hydraulic rod. During operation, the harvester completes alfalfa layering parting harvesting by the following three main steps of:harvesting alfalfa top layers, performing parting harvesting of stems and leaves, and harvesting the stems. The method for harvesting the alfalfa is not influenced by the weather, the loss of flowersand the leaves in the collection and storage process can be reduced, the separation harvesting of the stems and the flowers and leaves of alfalfa is realized, and high-quality primary grass products are provided.

Description

technical field [0001] The invention belongs to the field of agricultural machinery manufacturing, and in particular relates to an alfalfa layered fractal harvester and a harvesting method thereof. Background technique [0002] Alfalfa is a perennial leguminous herb with a plant height of up to 100cm. The leaves of the whole alfalfa plant account for about 45%-55% of the weight of the whole fresh grass. The leaves in the flowering stage are the most nutritious, and the crude protein content accounts for about 75% of the total plant. Harvest at the right time to reduce the loss of leaves during drying and transportation, and prevent Spoilage is an important measure to improve the nutritional content of grass products. [0003] When the alfalfa is harvested, the water content of the fresh alfalfa is about 75%. The existing methods for harvesting the alfalfa include: 1. After the alfalfa is harvested by a lawn mower or a grass flattener, it is dried in the field to make it rea...

Problems solved by technology

The disadvantage of this method is: the harvest time is greatly affected by the weather, and timely harvest cannot be guaranteed, especially the first crop harvest season coincides with the season of concentrated rainfall, which is easily caused by rain and temperature. During the process, the petioles, inflorescences and leaves are fragile under pressure, easy to fall, and the loss is large; during the drying process, the oxidation is intensified, the loss of carotene is intensified, and the loss of nutrients is greater

2. After the alfalfa is harvested, it is directly transported to the factory for industrial dehydration and drying. This method is characterized by fast drying speed and high protein content. The disadvantage is that the required equipment is expensive, consumes a lot of energy, and the aroma of grass products is poor.

This modulation method inevitably produces the phenomenon of loss of flowers and leaves, and has higher requirements on working tools

All these have seriously limited the deep processing channels of alfalfa and restricted the development of alfalfa industry in our country
