An intelligent controllable magnetorheological elastomer peanut fruit picking equipment

Abstract

The invention relates to intelligent controllable magnetorheological elastomer peanut fruit-picking equipment. The intelligent controllable magnetorheological elastomer peanut fruit-picking equipmentcomprises a fruit picking roller which is mounted on a machine frame, wherein a pair of parallel mounting shafts are fixedly mounted in the fruit picking roller; a primary fruit picking roller and a secondary fruit picking roller are separately and movably mounted on the parallel mounting shafts; a plurality of long and short magnetorheological elastomer elastic tooth groups are circumferentiallyarranged on the outer walls of the primary fruit picking roller and the secondary fruit picking roller at equal intervals; fruit picking roller steel bushings, with elastic tooth holes formed in surfaces, are arranged on the outer walls of the primary fruit picking roller and the secondary fruit picking roller in a sleeving manner; the long and short magnetorheological elastomer elastic tooth groups separately pass through the elastic tooth holes. According to the intelligent controllable magnetorheological elastomer peanut fruit-picking equipment disclosed by the invention, the magnetorheological elastomers can be designed into peanut fruit picking elastic teeth, by utilizing the characteristics of the magnetorheological elastomers in a peanut fruit-picking process, forms and rigidity ofthe magnetorheological elastomers can be changed by utilizing the size of a magnetic field of an electromagnet, so that the rigidity and the hardness of the fruit picking rollers can be changed in a 360-degree rotation process, and thus, the mechanical peanut fruit-picking efficiency is maximized and a breakage ratio of fruit picking is minimized.

Description

technical field [0001] The invention relates to an intelligent controllable magneto-rheological elastomer peanut picking device, which belongs to the field of agricultural machinery. Background technique [0002] At present, the peanut fruit-picking rollers used in agricultural production are composed of different forms such as helical rods with fixed intervals welded with bow teeth or elastic teeth, but the principle of fruit picking is roughly similar. The peanut pods are thrown out to the outside, and the peanut pods are separated from the stalks by impact, friction, pulling, rubbing, etc. between the peanut seedlings and the concave screen to achieve peanut picking. First of all, in the fruit picking method of this mechanical principle, the shell of the peanut pods will be damaged due to the impact of the spring teeth of the fruit picking roller on the peanut pods during the fruit picking process, which will increase the damage rate of peanut picking, make the harvested ...

Problems solved by technology

First of all, in the fruit picking method of this mechanical principle, the shell of the peanut pods will be damaged due to the impact of the spring teeth of the fruit picking roller on the peanut pods during the fruit picking process, which will increase the damage rate of peanut picking, make the harvested peanuts difficult to store, and directly or indirectly affect the peanut productivity. and economic value, reducing revenue

Secondly, if the rotating speed of the fruit picking roller is reduced to reduce the impact force between the peanut pods and the spring teeth to reduce the damage rate during the fruit picking process, the fruit picking will be dirty, which will directly affect the fruit picking efficiency of peanuts, thus increasing the labor time and cost.

Then, during the fruit-picking operation of the original fruit-picking roller, the fruit-picking roller entrains the seedlings and tendrils during the rotation operation, forming multiple rotations and cannot enter the lower roller or entangles the seedlings, which will block the fruit-picking roller and reduce the feeding of peanut seedlings.
