Abstract

An asymmetric corn header belongs to agricultural mechanical design technology. The invention is characterized in that a plurality of fixed bars in-line project vertically on the housing with a divider is mounted on the lower part of each fixed bar, while there being a channel between fixed bar, back of divider and housing; two strips of transport chains which can roll circulating housing are mounted on the housing for transporting plant with an installation of tooth-like part on said transport chains to fix plant and a snapping device is mounted on the back part of housing. Two said headers can further be paralleled to form broad corn header sharing one snapping device. The method provided can make a corn header have a plurality of small dividers which are far from ground and share one snapping device, therefore plant sloping slightly can be harvested while avoiding missing pressed plant; the short body of said corn header is operated flexibly to harvest various arrangements of planted corn mechanically.

Description

The non line composition type corn header

Technical field

The non line composition type corn header belongs to the Agricultural Machinery Design technical field, particularly the design of corn picker.

Background technology

The corn machine is received and has been classified national Tenth Five-year plan agricultural machanization tackling key problem emphasis problem as.The reaping machine of developing at present is parallel type, and promptly the nearside divider width of reaping machine is corresponding with the line width of milpa, plucks otherwise plant will be pushed over to cause Lou.Accompanying drawing 1 is the typical structure of existing maize harvesting machine, and 10 is nearside divider among the figure, and 11 is the dynamic power machine trailing wheel, and 12 is front-wheel; Its nearside divider is slightly grown, and the passage afterbody between per two nearside dividers all has an ear-picking unit; Its course of work is to allow milpa enter along the passage between nearside divider, and plant is cut off from root simultaneously by cant forward when plant arrives the passage afterbody, and the fringe pair roller of plucking that revolves is involved in, pulls back, and fruit ear is plucked the fringe guide groove and blocked, and separates with the stem stalk.If plant is compiled when the position of passage or passage and plant mismatches, plant can be pushed over by the nearside divider front end, and can not arrive the passage afterbody, can not be plucked fringe pair roller volume and live, and plucks thereby cause Lou.Because not matching of passage and plant position, two row or two strains enter a passage simultaneously sometimes, form triangular supports, also can't the admission passage afterbody, and cause two capable all being pushed over and leak and pluck.

One of unmatched reason of passage and plant position is position or the line-spacing irregularity of milpa; Another reason is because nearside divider and fuselage are long, add that dynamic power machine commonly used or tractor are rear-axle steering (are trailing wheel as 11 among Fig. 1), with front-wheel is a move left and right, machine is difficult for straight advancing in advancing, but about ceaselessly adjust direction, the nearside divider front end ceaselessly waves, and causes nearside divider passage and plant position not to match.In addition, fracture and leak and pluck if nearside divider front end rocking tendency when excessive, can cause the plant that just contacted to be caused by horizontal cant.Therefore, existing machine not only requires the plant line-spacing regular, and driver's driving technology is required very high, otherwise is exactly that the leakage situation of plucking can compare seriously for the regular plant of the line-spacing results of can not realizing ideal.Both made the very high driver of driving technology also can't realize the harvest corn at the edge of a field and turning.

The line-spacing of China's each department corn planting differs bigger, and the line-spacing on every ground is also not necessarily identical; The corn line-spacing of particularly interplanting pattern is just more lack of standardization, because of interplanting corn adopts wheat artificial planting in the ranks more.Utilize existing reaping machine to be difficult to realize corn is carried out ideal results, it is more serious that situation is plucked in leakage.This causes machine to be received and can not extensively implement, and the corn machine is received 2% of the not enough cultivated area of area at present.Therefore, developing well behaved non line composition type maize harvesting machine is one of key issue of large tracts of land popularization machine receipts.

Summary of the invention

The object of the present invention is to provide a kind of non line composition type maize harvesting machine and header, this header can be realized the corn of any arrangement plantation is carried out the machine receipts, solves the key technical problem of non line composition type maize harvesting machine.The scheme that is adopted is that a plurality of small size feed-type nearside dividers are set, and nearside divider is higher apart from ground, avoids plant is overwhelmed; Cooperating the plant chain then, the plant that all nearside dividers obtain concentrated, send in the ear-picking unit and finish fringe--bar separates.

The basic structure of non line composition type corn header as accompanying drawing 2 (a) (b) shown in.The invention is characterized in that stretch out the vertical dead lever (2) of a row on support, the lower end of each dead lever (2) is fixed with a nearside divider (1); Form an interconnection between described dead lever (2) and the support (6) and between the rear portion of nearside divider (1) and the support (6); A rotatable tooth guide wheel (4) that is used for plant is imported described interconnection is housed on described each nearside divider (1).On described support (6), have two can be around the chain that is used to carry plant (3) of support (6) rotation; The rice pressing tooth (5) that is used for firm plant is housed on described chain (3); In the lower end of described support (6) cutter (7) is housed; At the rear portion of described support (6) ear-picking unit (8) is housed.Cutter (7) and ear-picking unit (8) are prior art.

Another program of the present invention is characterised in that, contain two above-mentioned sub-headers placed side by side (its structure as shown in Figure 3), but an ear-picking unit (8) is housed at the rear portion of described header, it is relative that the chain of described two sub-headers (3) is carried the direction of plant, all towards ear-picking unit (8).

Compare with existing parallel type reaping machine, advantage of the present invention is:

Can realize the milpa of any arrangement is carried out the machine receipts more satisfactoryly.Required ear-picking unit is few because the parallel type machine each to nearside divider be exactly one independently get standing grain, pluck fringe, row's standing grain process, the machine of gathering in the crops several row just must have several ear-picking units.And the present invention sums up in the point that the plant that all nearside dividers obtain to pluck fringe and the processing of row's standing grain in the ear-picking unit.Fuselage is short, and nearside divider of the present invention will be lacked (little) nearside divider in existing machine far away.Because fuselage is short and need not the row results be cut, turn-take and cut so can be realized tilted direction, and radius of turn is little, it is convenient to turn, thereby the head of need not manually ceding territory, and opens inclined to one side road etc., can realize that more satisfactory diji receives.And the driving technology to the driver is not strict with.

Embodiment

Side feed-type non line composition type corn header structure is shown in Fig. 2 (a) and Fig. 2 (b), and each nearside divider (1) is hung fixing by vertical nearside divider dead lever (2), make the passage that forms a lateral direction penetrating between dead lever (2) and the support (6); One chain (3) is arranged around support (6) rotation (anterior chain direction of rotation is a right-to-left) in the passage, a same chain is also arranged at the bottom; Have the moon dentition formula rice pressing tooth of arranging by certain distance (5) on the chain; The rotatable sector guide wheel (4) of a horizontal positioned is housed on the nearside divider; A cutter (7) is equipped with in the lower end of support (6); There is an ear-picking unit (8) at header rear portion and nearside divider co-altitude place, straw chopping apparatus are housed below the ear-picking unit.Cutter (7), ear-picking unit (8) and straw chopping apparatus can adopt prior art.

Operation principle: header moves forward, milpa (9) is moved to the nearside divider rear portion by nearside divider (1) guiding earlier, sector guide wheel (4) on the nearside divider rotates under the drive of chain (3), plant is further pushed backward, and by rice pressing tooth (5) it is close to up and down and fixes on two chains, this moment, plant was cut off by the cutter sweep of root (7), on end plant is moved to a side (left side) under the drive of chain after cutting off, turn through the end, plant on end moves on to the rear portion of support (6), enters ear-picking unit (8) and plucks fringe.

Middle feed-type non line composition type corn header structure is shown in Fig. 3 (a) and Fig. 3 (b), by two side feed-type headers (being called sub-header) formation placed side by side, two sub-headers are reverse to the carriage direction of plant, at last plant are transported in the same ear-picking unit.Can be with two ear-picking units for accelerating harvesting speed.Promptly directly that two sub-headers are arranged side by side.This structure is suitable for wide cut reaping machine or header.By that analogy, also can increase a plurality of sub-headers according to the width of desire harvesting.

Key technology and innovative point: the passage of lateral direction penetrating is one of key of the present invention between the suspension fixed form of (1) nearside divider and nearside divider that forms thus and the support, it makes plant not only can resemble existing machine upper edge nearside divider and moves backward, and can realize laterally moving, can realize converging of plant thus, thereby a plurality of nearside dividers can be set and only use an ear-picking unit; Also be, exactly because can realize converging of plant, a plurality of undersized nearside dividers just can be set, make the line number of the quantity of nearside divider greater than corn, thereby realize that the plant that distributes does not arbitrarily need transition to tilt just can enter the afterbody of nearside divider, and realize results.Obviously, the quantity of nearside divider is many more in certain width, can adapt to more to arrange unordered harvest corn.(2) two chains up and down that rotate around support are another key points of the present invention, and it is to make the plant break-in move, and realize the specific implementation technology that plant is converged.
