Intermediate conveying device for self-propelled intelligent peanut seedling harvester

Abstract

The invention provides an intermediate conveying device for a self-propelled intelligent peanut seedling harvester. The harvester includes a header, an intermediate conveying device, a cutting and throwing device, a chassis with a traveling system, and an intelligent monitoring system for monitoring the working status. The intermediate conveying device has a first roller set comprising a front upper roller and a front lower roller; and a second roller set comprising a rear upper roller and a rear lower roller arranged on the rear side of the first roller set, by the The peanut seedlings cut by the header are transported to the cutting and throwing device via the first and second roller sets. The intermediate conveying device of the present invention is compactly configured to ensure stable clamping of each roller when peanut seedlings pass through the roller space, high working reliability and high conveying stability. It can adapt to the change of the thickness of the feeding material layer and ensure the pressing force on the material.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, and more particularly, to an intermediate conveying device for a self-propelled intelligent peanut seedling harvester. Background technique [0002] According to the latest statistics from FAO, the peanut harvesting area in my country in 2018 was 4.62 million hectares. 2 , with an output of 17.33 million tons, ranking second and first in the world, accounting for 16.2% and 37.7% of the world's total. Generally, the output of peanut seedlings per mu is equivalent to the output of peanut pods, that is, the annual output of peanut seedlings in my country is 17.33 million tons. If converted into fresh seedlings, the annual output is about 34 million tons. [0003] The data shows that the crude protein content of peanut seedlings exceeds 12%, the crude fat content reaches 2%, and the carbohydrate content exceeds 45%. The wheat grass is slightly higher, and the crude protein conten...

AI Technical Summary

Problems solved by technology

Discarded peanut seedlings have caused serious environmental pollution and waste of resources, and peanut seedlings used as feed are basically dried and then processed

Dried peanut seedlings will cause nutrient loss and are not easy to be digested by livestock and poultry. It is easy to cause forestomach relaxation or rumen food accumulation in animals, thus affecting the growth and development of animals.

Since the main peanut producing areas in my country generally adopt a two-stage method to harvest peanut pods (the first stage digging harvester digs the peanut plants, clears the soil, and lays them in strips to dry, and after drying to a certain moisture content, the second stage uses a pick-up combine harvester) Picking and picking fruit, or using field-type fruit picking machine to pick fruit after manual picking and collecting), because the picking-up combine harvester and field-type fruit picking machine are both full-feeding, that is, the entire peanut plant is fed into the fruit-picking device, resulting in Impurities such as soil are easily mixed in the peanut seedlings after picking up the combine harvester or fruit picking machine, which seriously affects the quality of peanut seedling feed

At the same time, due to the widespread use of film-covered peanuts in major production areas in my country, after two-stage harvesting, a large amount of plastic film is likely to be mixed in the peanut seedlings, which cannot be digested by livestock and poultry, and will accumulate in the stomach, resulting in digestion of livestock and poultry. bad or even death

[0005] In summary, there are four problems in the feed utilization process of peanut seedlings in my country: ① discarding peanut seedlings causes environmental pollution and waste of resources; ② dried peanut seedlings lose nutrients and are not easily digested by livestock; , The peanut seedlings are mixed with soil and other impurities, which reduces the feed quality. ④ The peanut seedlings planted with plastic film are harvested in the traditional way. The peanut seedlings are mixed with a large amount of plastic film and cannot be used as feed for livestock and poultry.

However, the existing intermediate conveying device for harvesting peanut seedlings has the problem of easy omission and accumulation of materials, and the work reliability is not high
