Embodiment mono-:
Referring to Fig. 1, Fig. 2 (Fig. 2 is vertical view), the corn combine harvester header that a kind of line-spacing is adjustable, comprise ceding of Taiwan body 1, described ceding of Taiwan body middle part sets a plurality of transmission cases 2 in a row, described each transmission case is fixedly connected with a harvesting frame 3, is in transmission connection step by step, wherein between two adjacent transmission cases by shaft coupling, the power transmission shaft of upper level transmission case 5 is provided with drive sprocket 6, and the power transmission shaft of next stage transmission case 7 is provided with driven sprocket 8; Described shaft coupling comprises a hollow axis body 9, and the two ends of described hollow axis body are provided with drive sprocket 10,11; The drive sprocket 6 of described upper level transmission case 5 is connected with drive sprocket 10 power of described shaft coupling one end by chain, and the driven sprocket 8 of described next stage transmission case 7 is connected with drive sprocket 11 power of the described shaft coupling other end by chain.
Referring to Fig. 2, in the present embodiment, described ceding of Taiwan body is provided with transmission case 2, harvesting frame 3, and described each transmission case and a harvesting frame are bolted to connection; Bo He mechanism 12, stem pulling roller mechanism 13 are set on harvesting frame, and the interior of said mechanism and annexation can be understood with reference to the ceding of Taiwan of disclosed maize harvesting machine in Chinese patent CN201690790U, are not described in detail herein.
Corn combine is when carrying out operation, and it is capable that corn planting is aimed at harvesting frame center 14, and the distance between two adjacent harvesting frame centers is results line-spacing.Difference due to corn line-spacing when planting, just needs corn combine can adjust corresponding line-spacing when operation, unrestricted while realizing trans-regional operation.In prior art, between two adjacent transmission cases, directly by chain, be in transmission connection step by step, results line-spacing is fixed.
Referring to Fig. 1, Fig. 2, in the present embodiment, between two adjacent transmission cases, by shaft coupling, be in transmission connection step by step, the transmission case of contiguous ceding of Taiwan body both sides is transmission case at the highest level, and the driven sprocket 15 of transmission case at the highest level is connected with the drive sprocket 16 on corn combine main shaft by chain.The power transmission shaft two ends of each transmission case are respectively equipped with drive sprocket, driven sprocket, and drive sprocket is arranged on a side of contiguous its next stage transmission case, and driven sprocket is arranged on a side of contiguous its upper level transmission case.Wherein, the power transmission shaft of upper level transmission case 5 is provided with drive sprocket 6, and the power transmission shaft of next stage transmission case 7 is provided with driven sprocket 8; Described shaft coupling comprises a hollow axis body 9, and the two ends of described hollow axis body are provided with drive sprocket 10,11; The drive sprocket 6 of described upper level transmission case 5 is connected with drive sprocket 10 power of described shaft coupling 4 one end by chain, and the driven sprocket 8 of described next stage transmission case 7 is connected with drive sprocket 11 power of described shaft coupling 4 other ends by chain.Chain described in the present embodiment is double strand chain (not shown).
In the present embodiment, shaft coupling adopts hollow axis body 9, makes the insertion shaft coupling that the power transmission shaft of two adjacent transmission cases can be appropriate inner, realizes the fine setting that reduces to gather in the crops line-spacing.
In the present embodiment, the length of described shaft coupling is 37～97 millimeters.The length of described shaft coupling can be selected at 37 millimeters between 97 millimeters, and the adjustable range of institute's corresponding row distance is 550～650 millimeters.The specification of at present the most frequently used shaft coupling has 37 millimeters, 67 millimeters, 97 millimeters.By that analogy, the shaft coupling that increases other specifications can further expand the adjustable range of line-spacing, but experiment showed, that when results line-spacing surpasses 700 millimeters, the weight causing due to shaft coupling increases, and must use reinforced chain drive, not recommendation.
Solving the adjustable problem while of line-spacing, owing to being subject to the width restriction of corn combine front tread and field-returning machine, occurring that front-wheel overwhelms the hidden danger that straw cannot be gone back field or field-returning machine leaks row.In Fig. 2, use the shaft coupling of a certain specification to regulate after line-spacing, front-wheel center 17 is far away apart from harvesting frame center 14, there will not be the situation that overwhelms straw; In Fig. 3, use the shaft coupling of another specification to regulate after line-spacing, the front-wheel center 17 of a side and a harvesting frame are centered close on same straight line, just exist tire to overwhelm the situation of straw.For solving this kind of pressure market condition, need to before overwhelming straw, tire cut off also field to straw.
Referring to Fig. 4, Fig. 5, for solving the row problem of pressing, further, described ceding of Taiwan body bottom arranges stubble-clearing device, described stubble-clearing device is provided with two mounting bracket plates 18, described two mounting bracket plates are provided with a cutting knife rotating shaft 19, and a plurality of tool rests 20 are equidistantly set in described cutting knife rotating shaft, on described tool rest, along rotation round, a plurality of blades 21 are equidistantly set.
