Double-flexible asparagus lettuce pulling, cutting and harvesting device

Abstract

The invention discloses a double-flexible asparagus lettuce pulling, cutting and harvesting device which comprises a rack. A righting device, a pulling-up device, a cutting device and a conveying device are sequentially arranged on the rack along a harvesting path, the pulling-up device comprises two clamping soft rollers which are matched with each other, and pulling-up threads are arranged on the outer walls of the clamping soft rollers; and the two clamping soft rollers pull up asparagus lettuce matched between the two clamping soft rollers in the opposite rotating process, the cutting device is used for cutting the pulled-up asparagus lettuce, and the conveying device is used for enabling the asparagus lettuce to sequentially pass through the pulling-up device and the cutting device. According to the asparagus lettuce harvesting device, automatic asparagus lettuce harvesting is achieved, a large amount of manpower is saved, the asparagus lettuce is pulled up in advance through the pulling-up device, the asparagus lettuce is cut as much as possible, waste caused by the fact that part of cut edible asparagus lettuce remains in soil is avoided, and asparagus lettuce integrity is kept to guarantee commodity of the asparagus lettuce.

Description

technical field [0001] The invention relates to a harvesting device, in particular to a double-flexible pulling and cutting harvesting device for lettuce. Background technique [0002] Lettuce is one of the important vegetable crops in China, but field production is a labor-intensive industry. It requires a lot of labor from seedling raising, planting, management and harvesting. The labor intensity is high, the labor efficiency is low, and the labor cost is high. The link is the most labor-intensive and time-consuming. Due to various reasons, the age structure of the personnel currently engaged in agricultural production tends to be aging, and the traditional strong physical field labor has led to a gradual decline in production efficiency. The price is getting higher and higher, and the problem of labor is becoming more and more prominent. The contradiction between the growth of vegetable demand and the increasingly low production efficiency has become prominent. The solut...

Problems solved by technology

[0002] Lettuce is one of the important vegetable crops in China, but field production is a labor-intensive industry. It requires a lot of labor from seedling raising, planting, management and harvesting. The labor intensity is high, the labor efficiency is low, and the labor cost is high. The most labor-intensive and time-consuming link

Due to various reasons, the age structure of the personnel currently engaged in agricultural production tends to be aging, and the traditional strong physical field labor has led to a gradual decline in production efficiency. The price is getting higher and higher, and the problem of labor is becoming more and more prominent. The contradiction between the growth of vegetable demand and the increasingly low production efficiency has become prominent. The solution is to use mechanized operations instead of manual labor to improve labor efficiency and reduce labor costs. Labor intensity, reduce labor cost

[0003] After several years of experiments and demonstrations, the land plowing and transplanting of some vegetables such as lettuce have been mechanized from the technical level, but the harvesting process is still manual, with high labor intensity and low labor efficiency. The biggest bottleneck of production is that there are few experimental demonstrations and related research reports on the mechanized harvesting of lettuce in China, and there are few production and manufacturing of lettuce harvesting equipment. There are almost no lettuce harvesting equipment suitable for the shallow hills and plains of Sichuan.
