Description
Technical field
The invention belongs to cotton harvesting machinery, particularly a kind of combined comb-tooth-type cotton picker with self-cleaning function.
Background technology
Xinjiang is the important cotton planting base of China, at present, and about 2,250 ten thousand mu of full boundary sown areas of cotton.Conventional adopt manually that cotton production efficiency is low, harvest time is long, the amount of labour used is big, condition is arduous, labour intensity is big, and every adopting cotton season not only mobilized government functionary, worker, student to participate in together and gathered, and must adopt cotton every year from employing 1,000,000 labourers help outside the province.However, the labour gathers and loses to still have a large amount of later stages to spend for want of.In addition, other provinces labour participates in cotton and gets the harvest in quickly work, brings problems for traffic, lodging, social security.Therefore, the growth requirement of the current Cotton Production of incompatibility of manually gathering, it is extremely urgent to greatly develop and promote mechanical harvesting.
The general main cotton trailer of picking desk, conveying plant, device for pre-cleaning and storage that comprises of conventional comb-tooth-type cotton picker, its operation principle is to utilize the cotton picker on the picking desk that the cotton comb is taken off, utilize conveying plant that the cotton of plucking is transported to device for pre-cleaning, will clear up back unginned cotton again and be delivered in the cotton trailer of storage.The comb-tooth-type cotton picker is in the course of work of plucking, general easy cotton leaf, cotton fruit spur, boll hull etc. are plucked together, cotton and cotton leaf are being delivered between the device for pre-cleaning from cotton-picker head, owing to be subjected to the repeatedly strike and the kneading action of external force, make cotton leaf more frangible and and cotton mix, very be difficult to cleaning, make cotton quality be subjected to very big influence, therefore, using comb-threshing-type mechanical picking cotton is that the requirement that reaches cotton ginning mill need increase the blowing dynamics, this not only can cause the cotton degradation, waits operating cost but also can increase cotton processing.
In addition, also have the blowing device is installed on the cotton picker, as ZL 200620008594.1, ZL 200710180035.8, ZL 200820103447.1, these patents all are to be the split configuration at picking head and blowing device, but this makes complete machine structure comparatively complicated, machine volume is also comparatively huge, and the facility cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of " modularization " combined comb-tooth-type cotton picker with self-cleaning function, because will comb off-type adopts cotton platform and moves the entire combination of " integrated " with cleaning plant, not only kept such and adopted that cotton platform is original not to have specific (special) requirements to cotton planting pattern line-spacing, the cropping pattern that can adapt to any line-spacing, and the cotton picker after the combination is carried out " zero distance " conveying, so have novel structure, compact, flow chart is simple and direct, maintaining is convenient, the facility cost is low, long service life, the operation fault rate is low, unginned cotton contains assorted advantage such as low, and can design by modular arrangements, also easily carry out the configuration of adopting cotton operation unit of " deflective traction " and " the contrary type of sailing " mode and self-propelled drum-type cotton picker is adopted cotton platform changing the outfit, reach the assembling form of different work facility with existing different big-powered tractor, the cotton fabric width of different mining, the apolegamy effect of different facility prices.
The object of the present invention is achieved like this: a kind of combined comb-tooth-type cotton picker with self-cleaning function, being included in front end on the frame is installed with by power-actuated chain-and-harrow type conveying plant and the blowing device that is made of U type sawtooth drum and steel wire cotton brushing roller, the cotton stalk pressure is installed on the frame of picking desk front portion leads device, uniform affixed the broach that is parallel to each other on crossbeam, the front end of broach is inclined upwardly, the power-actuated anti-roller of dialling is being set in the back lower place of broach, the chain-and-harrow type conveying plant that matches with broach is being set above broach, hello flower roller is being set at the discharging opening place of chain-and-harrow type conveying plant, the below of feeding the flower roller is being provided with the blowing device that is made of U type sawtooth drum and steel wire cotton brushing roller, and the cotton chamber of collection is being set at the rear portion of blowing device.
The present invention generally can with the supporting use of large-scale wheel tractor, also can with the use that changes the outfit of self-propelled cylinder type cotton picker.During work, when facility travelled forward, cotton plant was pressed to lead by cotton stalk and is successively entered into the broach gap that the picking desk upper comb dent forms from bottom to top by cotton plant middle and lower part to middle and upper part after device is pressed tiltedly, and moves along the carding tooth surface direction that is tilted to.Because the cotton boll diameter is bigger than cotton stalk diameter, littler than the spacing between the adjacent fingers, so by by force from the cotton plant combing get off.The anti-roller that pulls out of broach bottom can effectively avoid facility in operation process cotton to be eradicated.And collected cotton is transported to hello the flower roller place that its rear portion is provided with by the scraper plate on the chain-and-harrow type conveying plant that matches with carding tooth surface, and cotton reaches even, loose entering in the blowing device under the effect of feeding the flower roller at gravity.The unginned cotton of being drawn by the sawtooth hook travels forward with U type sawtooth drum, and when walking to wire brush, wire brush is evenly brushed unginned cotton and is attached to U type sawtooth drum surface, and impurity breaks away from U type sawtooth drum under centrifugal force and dirt rod iris action, directly be discharged in the cotton field.And the unginned cotton on the cylinder is brushed down when going to the cotton brushing roller place, drops down onto in the cotton chamber of collection.
The invention provides a kind of " modularization " combined comb-tooth-type cotton picker with self-cleaning function, because will comb off-type adopts cotton platform and moves the entire combination of " integrated " with cleaning plant, not only kept such and adopted that cotton platform is original not to have specific (special) requirements to cotton planting pattern line-spacing, the cropping pattern that can adapt to any line-spacing, and the cotton picker after the combination is carried out " zero distance " conveying, so have novel structure, compact, flow chart is simple and direct, maintaining is convenient, the facility cost is low, long service life, the operation fault rate is low, unginned cotton contains assorted advantage such as low, and can design by modular arrangements, also easily carry out preposition suspension type with existing different big-powered tractor, the deflective traction formula, contrary sail suspension type and the equipped formula of self-propelled type etc. mode be supporting articulate, reach the assembling form of different work facility, the cotton fabric width of different mining, the apolegamy effect of different facility prices.
