A spring tooth drum type peanut picking device

Abstract

The invention relates to a spring tooth roller type peanut pickup device and belongs to the technical field of agricultural machinery. The spring tooth drum type peanut pickup device comprises an open pickup roller, a roller slideway, pickup spring teeth and side plates, wherein the pickup spring teeth are uniformly fixed on a spring tooth shaft at intervals; a center shaft of the pickup roller passes through the left and the right side plates on the two sides and is connected with a bearing pedestal; the roller slideway is fixedly mounted in one of the side plates; one end of the spring tooth shaft is connected with the roller slideway through a crank cam mechanism; a roller of the crank cam mechanism is embedded into the roller slideway and is limited to roll in the slideway; the center shaft rotates and simultaneously drives the pickup roller to rotate; the shape of the roller slideway corresponding to each phase angle ensures the swing posture of each spring tooth on each station in the pickup process, so that the action on spring tooth pickup, lifting, pushing and backlash stations can be realized. According to the peanut plant pickup requirements, the initial posture and the swing rule of each pickup spring tooth on each station are determined. In the pickup process, the spring teeth gradually swing back, so that the strike of the spring teeth for peanut plants is reduced, and the pickup area is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a spring tooth drum type peanut picking device. Background technique [0002] In world oil production and international trade, peanut is one of the main foreign exchange-earning agricultural products, second only to soybean. In recent years, with the continuous increase of peanut planting area and output, the development of peanut production mechanization is particularly important. Our country started research on peanut combine harvesters at the beginning of this century, but due to agronomic influences such as plant traits, harvesting environment and planting methods, it has not been widely promoted. At present, small-scale machinery and manual segmental harvesting are still the mainstay, and the mechanization level of peanut harvesting is only 23.3%. [0003] At present, the knapsack peanut harvester with toothed belt pick-up device and the peanut harvester wit...

Problems solved by technology

However, these mechanical field experiments all have the problems of high missed picking rate and high fruit drop rate, which have become the key issues restricting the two-stage mechanical harvesting of peanuts.

[0004] Based on the comprehensive analysis of the principle of combining agricultural machinery and agronomy, it is found that the root cause is that various types of peanut picking and harvesting machines being developed in my country mainly use spring tooth picking devices suitable for rice, wheat and pasture or toothed belt picking suitable for rape However, the peanut picking device suitable for segmental or two-stage harvesting has not been studied in depth; while the American KMC peanut picking and harvesting machine is suitable for local creeping peanuts that form continuous strips after harvesting, it is difficult to meet the quality of laying after harvesting in my country. Poor upright peanuts, so there are serious problems of "stacking" and "throwing" of plants during the picking and harvesting process, and the loss of peanut machinery and fruit drop is very serious.
