Longitudinal poking wheel type corncob picking device

Abstract

The invention relates to a longitudinal poking wheel type corncob picking device which is a device used for being installed on a corn harvester for realizing a corncob picking function and belongs to the technical field of agricultural machinery. The corncob picking device comprises two groups of corncob picking mechanisms which are symmetrical on the left and the right and is characterized in that each group of corncob picking mechanism comprises poking wheel mechanisms, baffle plates and stem pulling rolls, and the poking wheel mechanisms and the stem pulling rolls are longitudinally arranged and respectively positioned at the upper ends and the lower ends of the baffle plates. When the corncob picking device works, the harvester transmits power to a transmission shaft, the transmission shaft rotates to drive poking wheel discs, poking teeth and poking fingers to rotate together, the stem pulling rolls convey corn plants downwards, and when corncobs are conveyed to the baffle plates, the poking wheel mechanisms pick the corncobs from top to bottom through the rotating poking fingers. The corncob picking device overcomes the defects of complex structure, great weight, large power consumption, low work efficiency and the like of a conventional roll type corncob picking device, provides a corncob picking mechanism simulating the operation of manually picking the corncobs, and has the advantages of simple structure, low cost, low power consumption, strong adaptability, and easiness for popularization and the like.

Description

technical field [0001] The invention relates to a corn ear picking principle and a corn ear picking device suitable for being installed on a corn harvester, belonging to the technical field of agricultural machinery. Background technique [0002] The ear picking device is the main working part of the corn harvester. At present, the main ear picking device is a roller-type ear picking device. The principle of this type of device is different from that of manual ear picking. The corn stalks are stretched, and the corn ears are forced to be squeezed to separate the stalks and ears. The method of picking ears is very unreasonable. The disadvantages of this type of ear picking device are that the structure of the ear picking device is complicated, the device is heavy, the power consumption is large, and the work efficiency is low, so the cost of corn harvesting remains high; Grain loss, although compared with the ear plate type, has the advantages of better ear picking effect an...
