Peanut harvester

Abstract

The invention discloses a peanut harvester which comprises a frame, an inner rack is arranged in the frame, the rear end of the inner rack is hinged to the front end of the inner rack, the inner rack can be adjusted up and down, and a first conveying belt and a second conveying belt are arranged in the inner rack, the upper side and the lower side of the first conveying belt and the upper side and the lower side of the second conveying belt are used for conveying vines and part of fruits backwards respectively, a first vine pulling roller, a second vine pulling roller and a scraper knife are sequentially arranged at the front end of the inner rack from top to bottom, the first vine pulling roller and the inner rack are rotationally installed, the included angle between the connecting line of the first vine pulling roller and the second vine pulling roller and the horizontal plane is adjustable, and the shaft distance between the first vine pulling roller and the second vine pulling roller is adjustable. According to the peanut harvester, vines and fruits are separated from soil together in the mode that soil is loosened first and then vines are pulled out, soil loosening is promoted through the design of the shaking scraper knife, separation of the fruits and the soil is facilitated, and the fruit loss rate is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery automation, in particular to a peanut harvester. Background technique [0002] Traditional peanut harvesting is mostly done manually. With the advent of agricultural mechanization, automated peanut harvesters have begun to appear. When the existing peanut harvesters are operating, there will be relatively large dust, which is no less than a small sandstorm. It has a great impact on the local environment and does not conform to the existing green development concept. For some areas, the use of this type of equipment has been banned. The root cause is that the harvester collects peanut seedlings and fruits from the soil. The existing The harvester adopts the method of directly entering the ground with a shovel, scoops up the fruits, seedlings, and soil together, and sends them to the conveyor belt. During the transmission process, the soil is crushed and screened. And in the process ...

[0002]Traditional peanut harvesting mostly uses manual extraction. With the emergence of agricultural mechanization, automated peanut harvesters have begun to appear. When the existing peanut harvesters are operating , there will be larger dust, which is no less than a small sandstorm, which has a great impact on the local environment and does not conform to the existing green development concept. For some areas, the use of this type of equipment has been banned. The root cause is that the harvest The machine collects peanut seedlings and fruits from the soil. The existing harvester adopts the method of directly entering the ground with a spatula, scoops up the fruits, seedlings, and soil together, and sends them to the conveyor belt. During the transmission process, the soil is crushed. Screening, the process is supplemented by wind for winnowing, causing dust to fly, and in the process of sorting seedling fruits and soil, most of them are carried out by rolling. One piece was screened out, resulting in an increase in the fruit loss rate; and for some plots, there were many stones inside, and the front end of the shovel touched the stones during the feeding process, which could easily cause the blade to collapse and cause equipment damage; at the same time Although the existing vehicles have been light-weighted and the driver will selectively avoid rolling over the unharvested plots during harvesting, it is still unavoidable that some areas will be rolled over, resulting in serious soil compaction, and the soil will be scooped up by the shovel Finally, the fruit and the soil are tightly combined due to rolling and are not easy to separate, which also makes it more difficult to harvest the fruit and is not easy to reduce the fruit loss rate
