Intermediate conveying device for self-propelled intelligent peanut vine harvester

Abstract

The invention provides an intermediate conveying device for a self-propelled intelligent peanut vine harvester. The harvester comprises a header, the intermediate conveying device, a cutting and throwing device, a chassis with a walking system and an intelligent monitoring system used for monitoring the operation state. The intermediate conveying device is provided with a first roller set comprising a front upper roller and a front lower roller, and a second roller set which is arranged at the rear side of the first roller set and comprises a rear upper roller and a rear lower roller; and peanut vines cut by the header are conveyed to the cutting and throwing device through the first roller set and the second roller set. The intermediate conveying device is compact in configuration, so that when the peanut vines pass through a space between the rollers, the rollers are clamped stably, the working reliability is high, and the conveying stability is high. The feeding device can adapt to the thickness change of a fed material layer, and can ensure that materials have pressing force.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, and more specifically, relates to an intermediate conveying device for a self-propelled intelligent peanut seedling harvester. Background technique [0002] According to the latest statistics from the FAO, in 2018 my country's peanut harvest area was 4.62 million ha 2 , with an output of 17.33 million tons, ranking second and first in the world respectively, accounting for 16.2% and 37.7% of the global total. Generally, the yield of peanut seedlings per mu is equivalent to that of peanut pods. That is to say, 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] According to the data, the crude protein content in peanut seedlings exceeds 12%, the crude fat content reaches 2%, and the carbohydrate content exceeds 45%. Wheatgrass is slightly taller, and its crude protein...

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
