Corn harvesting device capable of changing harvesting line spacing and preventing jamming

Abstract

The invention relates to the technical field of corn harvesting, and discloses a corn harvesting device capable of changing harvesting line spacing and preventing jamming. The corn harvesting device comprises a support frame, first motors are fixedly mounted at the top end in the support frame, rotating shafts are fixedly connected to the top ends of the first motors, pulley blocks are fixedly connected to the top ends of the rotating shafts, fixed plates are fixedly mounted at the bottom ends of the pulley blocks, the surfaces of the pulley blocks are in transmission connection with belts, and the outer sides of the belts are fixedly connected with limiting blocks. The positions of third belt wheels, fourth belt wheels and fifth belt wheels are changed by manually adjusting the positionsof the fixed plates, then the distance between the two pulley blocks is changed, the corn harvesting device adapts to corn with different planting distances in different areas, second threaded rods are manually adjusted, the second threaded rods drive sliding blocks to move, the sliding blocks drive ear picking rollers rotationally mounted on the surfaces to move, the distance between the ear picking rollers is changed according to the sizes of separated corn, the harvesting efficiency is greatly improved, and the probability of equipment jamming is reduced.

Description

technical field [0001] The invention relates to the technical field of corn harvesting, in particular to a corn harvesting device capable of changing the harvesting line spacing and preventing jamming. Background technique [0002] my country is a big corn producing country in the world, but the corn harvester is not popular, the main reason is that the price of the corn harvester is high, it cannot adapt to the corn grown in different origins at the same time, and the maintenance is troublesome. For the planting of different varieties of corn, people Grain dividers of different specifications are required, and the cost is high. When the corn harvester is stuck, not only maintenance is troublesome but also time-consuming. [0003] In order to solve the above problems, the inventor provides a corn harvesting device that can change the harvesting line spacing and prevent jamming. By manually adjusting the position of the fixed plate, the positions of the third pulley, the fourt...
