Corn harvester based on visual detection technology

Abstract

The invention discloses a corn harvester based on a vision detection technology. The corn harvester based on the vision detection technology comprises a trailer mechanism, an ear treatment mechanism,a straw treatment mechanism, a kernel filtering mechanism, an orientation adjusting mechanism and a CCD image acquisition assembly. According to the corn harvester based on the vision detection technology, the growth position information of corn ears can be collected through the CCD image collecting assembly, and the ear treatment mechanism is horizontally conveyed to the growth position of the corn ears in cooperation with a horizontal position sensing assembly which controls the orientation adjusting mechanism; the ear treatment mechanism sequentially carries out operations such as ear picking, conveying and threshing on the corn ears, and finally, dropped corn kernels are conveyed to the kernel filtering mechanism through a kernel conveying pipe. The corn harvester based on the vision detection technology is compact in structure, high in degree of automation and high in harvesting efficiency, the ears can be accurately picked and threshed, the threshed kernels can be purified and processed, the corn straws can be chopped and returned to the field, and the corn harvester is favorable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of corn harvesting equipment, in particular to a corn harvester based on visual detection technology. Background technique [0002] Corn is one of the four major food crops in China and is widely planted in my country. The traditional corn harvesting process usually consists of a series of processes, such as manually picking the ear from the stalk, cutting down the stalk and moving it away from the harvest area, and sending the ear to the threshing device for operation. With a lot of manpower. As a result, a large number of corn harvesters have emerged to solve the above problems. However, during the corn harvesting process, due to differences in the growth height of corn ears, the harvester will miss the corn ears in the operation process, resulting in low corn yields, resulting in Loss of grain sources; the existing corn harvester cannot cut off the stalks after picking the ears, and the machine will ove...

The traditional corn harvesting process usually consists of a series of processes, such as manually picking the ear from the stalk, cutting down the stalk and moving it away from the harvest area, and sending the ear to the threshing device for operation. with a lot of manpower

As a result, a large number of corn harvesters have emerged to solve the above problems. However, during the corn harvesting process, due to differences in the growth height of corn ears, the harvester will miss the corn ears in the operation process, resulting in low corn yields, resulting in Loss of grain sources; the existing corn harvester cannot cut off the stalks after picking the ears, and the machine will overwhelm the stalks after picking the ears to the ground during the harvesting process, which will cause a large power consumption of the harvesting device and have no effect of returning the straws to the field; In addition, the existing harvester lacks the grain cleaning function, and the grain is mixed with a large amount of sundries after being threshed, and the purity is poor
