The walking chassis comprises a walking chassis frame, a walking gearbox, a waling wheel train and driving wheels installed on the walking gearbox and a crawler belt of the waling wheel train, wherein the walking chassis frame is divided into an upper frame and a lower frame, the walking gearbox is fixedly arranged on the upper frame, the waling wheel train is fixed on the lower frame, an elevating system is arranged between the upper frame and the lower frame, and the elevating system comprises two sets of swing arm elevating systems which is symmetrically arranged as the crawler belt on the two sides and moves synchronously. Each swing arm elevating system comprises a first swing arm, a second swing arm, a support member, an oil cylinder and a horizontal pull bar, wherein the first swing arm rotates and drives the upper frame to ascend and descend horizontally via the support member, the oil cylinder and the horizontal pull bar. The walking chassis enables the harvester to be adapted to farmlands varied in mud depth, thereby preventing the lower portion of the walking gearbox from pushing mud, and expanding the application scope of the harvester.
Description
Technical field
The utility model relates to field of agricultural machinery, particularly a kind of walking chassis of rice combine.
Background technology
Grain header is the machinery of integrated harvesting crops, can disposablely complete harvesting, threshing, and grain is focused on to collection granary, and then by conveyer belt, grain is transported on transport vehicle.Can say in modern agriculture harvesting and be widely used, and result of use is also very good.
But in the triple cropping of rice, the double cropping rice area of China, the mud pin of paddy field is generally deep, the operation of generally can not normally going to the field of larger rice combine.Because the mud pin of paddy field is deep, rice combine sink serious, causes moving gear box to land, and rice combine occurs that moving gear box pushes away mud phenomenon when walking.Walk very difficult, occur sometimes situation about cannot walk.In the triple cropping of rice, double cropping rice area, use small-sized rice combine (swath is the 1.2 meters of left and right) operation of going to the field, and small-sized rice combine harvesting efficiency is low, harvesting cost is relatively high.At present, in order to allow the larger rice combine can operation at the triple cropping of rice, double cropping rice area, the way of producer be the way that directly adopts Widened track, reduces the grounding pressure of rice combine, prevents from sinking serious.Consider from the angle of complete machine but lack comprehensively, caused the inharmonious of some complete machine aspects.The most obvious, make machine steering drag increase, dumb, while turning to, moving gear box load strengthens.
Utility model content
The purpose of this utility model is to provide one can make grain header adapt to the various mud pin degree of depth, avoids moving gear box to push away the walking chassis of the rice combine of mud phenomenon appearance.
The technical scheme that realizes the utility model object is: the utlity model has walking chassis main frame, moving gear box, walking wheel and be arranged on the crawler belt on driving wheel and the walking wheel on moving gear box; Described walking chassis main frame is divided into upper and lower two-layer, and upper strata is upper spider, and lower floor is lower bearing bracket; Described moving gear box is fixedly installed on upper spider, and walking wheel is fixedly installed on lower bearing bracket; Between described upper spider and lower bearing bracket, be provided with elevating mechanism; Described elevating mechanism is made up of the Liang Zu swing arm lifting mechanism being symmetrical arranged and be synchronized with the movement the same as both sides crawler belt; Described swing arm lifting mechanism comprises the first swing arm, the second swing arm, support member, oil cylinder and girt; One end and the lower bearing bracket of described the first swing arm are movably hinged, and the other end is fixedly connected with one end of support member, and the push shaft end of the other end of support member and oil cylinder is movably hinged, and oil cylinder is fixedly installed on upper spider; One end and the lower bearing bracket of described the second swing arm are movably hinged, and the other end and upper spider are movably hinged; In described gripper shoe, between two ends, be provided with anchor point, one end and the upper spider of girt are movably hinged, and the other end and anchor point are movably hinged; Two tie points of two tie points of described the first swing arm and the second swing arm form parallelogram, and the tie point place of the tie point of the first swing arm and lower bearing bracket and the second swing arm and lower bearing bracket in the same horizontal line.
Above-mentioned the second swing arm is arranged on the side near moving gear box.
Above-mentioned the first swing arm and the second swing arm equal in length.
The utlity model has positive effect: (1) the utility model can improve the height on moving gear box and ground, therefore can adapt to the farmland of the various mud pin degree of depth; (2) the utility model is simple in structure, low production cost, but can play lifting effect very stably; (3) the utility model can improve the scope of application of grain header greatly, improves the crop harvesting efficiency of certain areas; (4) the utility model has avoided moving gear box to push away the generation of mud phenomenon effectively, has not only improved production efficiency, and can increase to a certain extent the service life of moving gear box.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, the utlity model has walking chassis main frame, moving gear box 1, walking wheel 2 and be arranged on the crawler belt 3 on driving wheel 1-1 and the walking wheel 2 on moving gear box 1; Described walking chassis main frame is divided into upper and lower two-layer, and upper strata is upper spider 4, and lower floor is lower bearing bracket 5; Described moving gear box 1 is fixedly installed on upper spider 4, and walking wheel 2 is fixedly installed on lower bearing bracket 5; Between described upper spider 4 and lower bearing bracket 5, be provided with elevating mechanism; Described elevating mechanism is made up of the Liang Zu swing arm lifting mechanism being symmetrical arranged and be synchronized with the movement the same as both sides crawler belt 3; Described swing arm lifting mechanism comprises the first swing arm 6, the second swing arm 7, support member 8, oil cylinder 9 and girt 10; One end of described the first swing arm 6 and lower bearing bracket 5 are movably hinged, and the other end is fixedly connected with one end of support member 8, and the push shaft end of the other end of support member 8 and oil cylinder 9 is movably hinged, and oil cylinder 9 is fixedly installed on upper spider 4; One end of described the second swing arm 7 and lower bearing bracket 5 are movably hinged, and the other end and upper spider 4 are movably hinged; In described gripper shoe 8, be provided with anchor point 8-1 between two ends, one end of girt 10 and upper spider 4 are movably hinged, and the other end and anchor point 8-1 are movably hinged; Two tie points of two tie points of described the first swing arm 6 and the second swing arm 7 form parallelogram, and the tie point place of the tie point of the first swing arm 6 and lower bearing bracket 5 and the second swing arm 7 and lower bearing bracket 5 in the same horizontal line; Described the second swing arm 7 is arranged on the side near moving gear box 1; Described the first swing arm 6 and the second swing arm 7 equal in length.
When grain header when operation, can reduce upper spider 4 at smooth road traveling or in the not dark paddy field of mud pin, the center of gravity of grain header is declined, increase its stability; When grain header runs into special circumstances and need to improve trafficability characteristic on road surface, the upper spider 4 that can raise, moving gear box 1 also raises simultaneously, guarantees passing through of grain header; When grain header is in the paddy field of dark mud pin when operation, can be by the elevating mechanism upper spider 4 that raises, moving gear box 1 also raises simultaneously, thereby has avoided affecting the phenomenon of harvesting because the bottom of moving gear box 1 pushes away mud.
