Abstract

The utility model discloses a picking device of a cotton harvester. The picking device comprises comb teeth (1) arranged side by side. The key point is that the comb teeth (1) are arranged on a transverse oscillating rod (5), an oscillating rod driving mechanism is arranged on the oscillating rod (5), and a shift-prevention roller (2) is arranged at the lower parts of the comb teeth (1) arranged side by side. Compared with the prior art, the comb teeth arranged side by side are matched with the shift-prevention roller while vibrating vertically accordingly in the walking process of a cotton harvesting machine and can comb cotton off from a cotton stem under the condition of not pulling up the cotton stem, and simultaneously the vibrating comb teeth apply a backward throwing force to the picked cotton, so as to avoid blockage of the cotton at the front sections of the comb teeth; and simultaneously, the vibrating comb teeth can discharge part of impurities in the cotton from clearances between the adjacent comb teeth while conveying the cotton backwards.

Description

The picker of cotton harvesting machine

Technical field

The utility model relates to the picker of a Cotton Harvesters.

Background technology

In the cotton planting of dry area in north china, substantially adopted the mulching planting pattern at present, under this cropping pattern, cotton plant is taken root generally more shallow in process of growth, so cotton stalk is more easily lifted.

Progressively popularization along with the mechanical harvest cotton, a problem also is exposed: namely in the cotton harvesting process, cotton plant is easy to be pulled up by cotton harvesting machinery, common comb-tooth-type cotton picker is when carrying out cotton harvesting, its broach is easy to cotton stalk be uprooped and together be incorporated into cotton, and the one, the impurity content of cotton greatly promotes, and the 2nd, bring difficulty to the follow-up cleaning work of cotton, particularly the residual film in the mulching film planting is brought in the unginned cotton, had serious consequences for later cleaning.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of under the present mulching planting pattern, the picker of the cotton harvesting machine that in the time of can preventing from gathering cotton stalk be pulled up, particularly a kind of picking head of comb-tooth-type cotton picker.

The purpose of this utility model realizes by following structure: comprise broach (1) side by side, its main points are that described broach (1) is arranged on the horizontal swing arm (5), swing arm (5) is provided with the swing arm driving mechanism, described driving mechanism is eccentric mechanism, comprise eccentric wheel (3), connecting rod (4) and swing arm (6), swing arm (6) is connected with swing arm (5) also so that swing arm (5) generation radially wobbles, and then so that broach swing take swing arm (5) as axle, described broach (1) bottom side by side is provided with the anti-roller (2) that pulls out, should anti-pull out roller (2) and comprise axis body (2-2), axis body (2-2) is provided with axial plate body (2-1), and the edge of plate body (2-1) is provided with jagged ripple.

As improvement, above-mentioned broach (1) preferably structure is as follows: comprise denticle (1-2), the cross section of denticle (1-2) is " V " type, and it is contraction-like and be provided with finger-type column (1-1) gradually that denticle (1-2) leading section is.

As further improvement, above-mentioned denticle (1-2) bottom preferably is provided with cutter shape riser (1-3)

Compared with prior art, when the utility model broach is side by side done up-down vibration in being accompanied by the process of cotton picker walking with prevent that pulling out roller matches, can in the situation about cotton stalk not being pulled up with cotton from the cotton stalk under the combing, the broach of vibration throws power for one in the cotton that picks backward on the other hand, avoided cotton to stop up at the broach leading portion, simultaneously, the broach of vibration can be discharged a part of impurity in the cotton when carrying cotton backward in the middle of the slit of adjacent fingers.
