Pull-cut type white asparagus harvesting end effector and harvesting method

Abstract

The invention relates to a pull-cut type white asparagus harvesting end effector and a harvesting method. The end effector comprises upper and lower fixing plates, supporting plates, left and right stick knives and a pull-cut mechanism; the upper and lower fixing plates are used for supporting the pull-cut type white asparagus end executor so that the white asparagus harvesting end executor can beinserted into and pulled out of soil; the supporting plates have a fixing and supporting effect; the left and right stick knives penetrate into soil; and the pull-cut mechanism is used for cutting the roots of white asparagus. According to the end executor and the method, root cutting, pulling and throwing of the white asparagus are achieved by driving the harvesting end executor to move, and thewhite asparagus harvesting efficiency is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a pull-cut type white asparagus harvesting end effector and a harvesting method, so as to realize root cutting, pulling, and throwing operations of white asparagus without digging and backfilling. [0002] technical background [0003] Asparagus is a highly nutritious and healthy vegetable that is popular with consumers. Asparagus is also known as Shi Diaobo. It is divided into white asparagus and green asparagus. Its taste is more delicious than green asparagus, and it is rich in nutrition. It is known as the "king of vegetables" and "one of the top ten famous dishes in the world". [0004] my country's asparagus industry is developing rapidly, and it is the world's largest asparagus producer and exporter. In 2011, the global asparagus harvested area reached 1.46 million hectares, and my country's asparagus harvested area reached 1.32 million hectares, accounting for 90% of th...

Problems solved by technology

Most of the white asparagus harvesting tools are slender asparagus knives. In addition, the harvesting time of white asparagus is usually before the sun comes out in the morning or after the sun goes down in the evening. The harvesting time is relatively concentrated, and the harvesting process is time-consuming and heavy. Harvesting efficiency of white asparagus is very low

[0005] After searching the literature of the prior art, it was found that the Chinese invention patent "A Device and Method for Harvesting White Asparagus with Clip-cutting" Patent Application No. 201610887545.8 adopts the clamping and cutting method to harvest white asparagus. This harvesting method exists The following aspects need to be improved: ①The design of the mechanical structure is complicated, and there are many steps in the clamping and cutting action; ②The cutting blade needs additional blade protection, and the resistance to entry into the soil is relatively large; ③The splint will cause mechanical damage to the white asparagus during the harvesting process.
