Dust suppression device of peanut pick-up harvester

Abstract

The invention provides a dust suppression device of a peanut pick-up harvester. The peanut pick-up harvester is provided with a vine collecting box, a riddling wind riddle and a fruit picking device,wherein an upward exhaust opening is formed in a top surface of the vine collecting box. The dust suppression device is composed of a fugitive dust recovering pipe and a wind leveling device, whereinone end of the fugitive dust recovering pipe is connected with the exhaust opening, and the other end of the fugitive dust recovering pipe is connected with the riddling wind riddle and / or fruit picking device through the wind leveling device; and the wind leveling device is provided with a tubular shell, a plurality of wind guiding pipes which are of concentric-circle distribution are fixed in the tubular shell, the smaller the diameter of each wind guiding pipe, the longer the length of each wind guiding pipe, end faces of the wind guiding pipes close to a wind inlet side are level, an annular step, which is abutted against the internal wall of the tubular shell, is arranged at the end face of the other end of each wind guiding pipe, and a wind outlet groove is divided into a plurality of air outlets by the annular steps. According to the dust suppression device of the peanut pick-up harvester, height of fugitive dust is lowered through changing an exhaust gas emission direction of the vine collecting box of the peanut pick-up harvester, meanwhile, an air exhaust volume of an air blower of the riddling wind riddle can be reduced, and probability of interaction between fruit picking spike teeth and peanut vines is increased.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a dust suppression device for a peanut picking and harvesting machine. Background technique [0002] As an important oil crop and high-quality protein resource, peanut is in the forefront of the world in terms of planting area and output in my country. According to statistics from the Food and Agriculture Organization of the United Nations (FAO), in 2016 China's peanut planting area was 4.75×10 6 hm 2 , accounting for 16.68% of the world; output 1.7×107 t , accounting for 40.26% of the world. Peanut seedlings are rich in crude protein, crude fat and carbohydrates, and are excellent feed for livestock and poultry. Generally, the output of peanut vines per mu is equivalent to that of pods, that is, the annual output of peanut vines in my country is nearly 17 million tons. [0003] my country's peanut planting is widely distributed, mainly concentrated in Henan, Shandong, Guangdong, He...

Problems solved by technology

In addition, the soil entrained on the peanut seedlings caused a lot of dust from the exhaust port of the seedling collection box during harvesting, which sprayed into the air like a chimney, up to 20 to 30 meters; if there was wind during harvesting, the dust would stretch for hundreds of meters, increasing Air PM2.5 content around nearby villages, causing environmental pollution
