Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural harvesting machinery technical field, concretely relates to a kind of telescopic wire harness structure for corn harvesting machinery granary secondary lifting. BACKGROUND

[0002] Corn harvesting machinery, header completes ear picking, and chain rake lifter is used to push ear to bract peeling mechanism, and after completing bract removal, it is sent to granary, and the harvesting process is completed.In the process of grain collection, due to the special situation of grain transport vehicle, the main machine for large land operation often uses large truck to transport grain, and the rear hopper of the truck needs to increase the baffle, and the unloading height is generally between 4.0 and 4.5 meters.The corn harvesting machine factory generally releases the secondary high unloading device of granary, and the unloading height is increased to about 4.5 meters.

[0003] With the increase of unloading height, the video detection line, grain full alarm line (or increased lighting or other auxiliary electrical devices) required by the grain lifting device during lifting also moves up and down with the lifting device, and the wire harness is repeatedly folded during movement, which causes early wear of the wire harness, and even causes wire harness jamming or breakage, causing interruption of electrical detection signal, and some positive and negative power lines are adhered and short-circuited, causing failure of other related electrical appliances.

[0005] As a preferred scheme: the C end telescopic wire has elastic elongation, which can compensate the distance difference caused by the change of the height position of the granary.

[0006] As a preferred scheme: when the granary is lifted to the highest point of unloading position, the elasticity of the C end telescopic wire can meet the maximum extension limit requirement.

[0007] As a preferred solution: when the grain bin drops to the lowest point, the C-end telescopic wire restores to the smallest original size.

[0008] As a preferred solution: it also includes auxiliary electrical element connecting wire, which realizes synchronous movement with the grain bin secondary lifting device through the telescopic wire harness.

[0009] As a preferred solution: the bottom bin sensor and the bottom bin camera are arranged on the grain bin secondary lifting cylinder mounting bracket, so that the signal transmission stability at different heights is ensured.

[0010] Due to the adoption of the above technical scheme, compared with the prior art, the utility model has the advantages of:
