Description
Technical Field
The invention relates to the technical field of agricultural machinery, in particular to a novel peanut picking harvester.
Background
With the rapid development of automation technology, more and more automation devices are applied to the production fields of industry, agriculture and the like, in particular to the agricultural production field. And the automation of agricultural mechanical equipment greatly improves the yield and the working efficiency of agricultural production.
The automatic peanut picking harvester can sequentially finish the operations of digging or pulling out peanuts, separating soil, picking fruits, cleaning and the like, and the specific operation process is generally as follows: the peanut seedling after being aired for a period of time is automatically fed into a picking chamber through a picking table and a bridge, the peanut is separated from stems by rotating and striking a roller picking rod, fruits and sundries fall onto a vibrating screen through a concave plate hole, and the working procedures of screening fans, fruit augers, fruit throwing impellers, re-threshing augers, stem cutting devices, grass discharging fans and the like are carried out to complete the work of separating the peanut seedling, crushing the seedling rods, cleaning, harvesting, collecting and the like.
When the existing peanut picking harvester is in actual use, the cleaned peanuts can be conveyed into the peanut storage box in a pressed mode through the peanut throwing cylinder in an air flow pressing mode. Under the action of specific air flow and air pressure, the fruit shell can be instantly thrown out by the fruit throwing cylinder at a certain speed and in a certain direction, so that fruit particles in the fruit shell are crushed; moreover, the cleaned peanuts are conveyed into the peanut storage box in a pressing mode through air flow generated by the peanut throwing fan, the air quantity generated by the conventional peanut throwing fan is fixed, but the peanut storage box is easy to cause high peanut shell and seed crushing rate if the peanuts are conveyed into the peanut storage box in a pressing mode through air flow generated by the fixed air quantity due to different varieties of peanuts and different specific gravities of the peanuts in the yield and the dryness and humidity degree. That is, the existing peanut picking harvester has a high breaking rate.
The working process of the grass discharging fan of the existing peanut picking harvester is as follows: the stalks and the crushed leaves after picking and cleaning are further crushed by the cutter and then sucked out by the grass discharging barrel and discharged into the grass box under the action of the grass discharging fan. When the existing peanut picking harvester is actually used, the wind speed of a grass discharging fan of a grass discharging barrel is easy to be reduced and the grass discharging barrel is easy to be blocked due to various reasons such as dry and wet conditions of stalks, fruit seedlings, feeding quantity and the like; in addition, whether the rotation speed of the grass discharging fan can rotate at a constant speed reaches a preset rotation speed is related to whether the whole peanut picking harvester can work normally, otherwise, the phenomena of blocking the grass discharging cylinder and the like caused by seedling grass can be caused. When the triangular belt of the grass discharging fan of the existing peanut picking harvester is loosened, the wind speed of the grass discharging fan is reduced, so that the preset rotating speed cannot be reached, and the normal work of the peanut picking harvester is affected. That is, the grass discharging tube of the existing peanut picking harvester is easy to be blocked, and the normal use of the peanut picking harvester is affected.
