Detailed description of the invention
The embodiment of combined harvester foot pedal accelerator device of the present invention: as shown in Figure 1 and Figure 2, comprise combining Rack Body 1, Das Gaspedal 6, transmission device, acceleration cable 8 and returning pull-spring 10, Das Gaspedal 6 is obliquely installed and is hinged on the upper surface of combining Rack Body 1, and the upper surface of combining Rack Body 1 is the upper face of bottom plate of driving cab; End is trampled for its power in the upper end of Das Gaspedal 6, and power is trampled end and is connected by the power intake of transmission device with acceleration cable 8, and one end of returning pull-spring 10 is connected on acceleration cable 8, the other end is connected on combining Rack Body 1.In the process of lower accelerator pedal 6, Das Gaspedal 6 drives the power intake of acceleration cable 8 to move with open the throttle wide by transmission device, and throttle extension spring 10 is simultaneously extended and applies opposite effect power to Das Gaspedal 6; Unclamping the process of Das Gaspedal 6, Das Gaspedal 6 return under the elastic force of throttle extension spring 10.Take upper part as prior art or can be realized by prior art.Described transmission device comprises connecting lever 2 and throttle push rod 5, the two ends of connecting lever 2 are respectively power intake and clutch end, its flex point 4 is arranged on combining Rack Body 1 to realize the rotation of connecting lever 2, the clutch end of connecting lever 2 is connected with the power intake of acceleration cable 8, and one end of throttle push rod 5 and the power of Das Gaspedal 6 are trampled and held the power intake of hinged, the other end and connecting lever 2 hinged.The below that the upper surface of combining Rack Body 1 is positioned at Das Gaspedal 6 is fixed with a position limiting structure, and in the present embodiment, position limiting structure is caging bolt 7, and the upper end of caging bolt 7 is higher than the upper surface of combining Rack Body 1; In addition, be also provided with a return force application structure at the lower end position of Das Gaspedal 6, return force application structure is the return stampeding section 9 be fixed in Das Gaspedal, and the lower end of Das Gaspedal 6 is stretched out in one end of return stampeding section 9.
Das Gaspedal 6 under the process stepped on comprise one by the process of start bit to maximum throttle position: start bit state as shown in Figure 1, Das Gaspedal 6 is in maximum inclination state, and returning pull-spring 10 keeps normal; Lower accelerator pedal 6, Das Gaspedal 6 applies application force by the power intake of throttle push rod 5 pairs of connecting levers 2, thus connecting lever 2 is rotated around flex point 4, meanwhile, the elastic force that the clutch end of connecting lever 2 overcomes returning pull-spring 10 pulls the power intake of acceleration cable 8 to circle together around flex point 4, thus realizing open the throttle wide gradually, throttle extension spring 10 is also extended gradually; Das Gaspedal 6 under the process stepped on, acceleration cable 8 is drawn close to flex point 4 gradually, until when acceleration cable 8 intersects with flex point 4, Das Gaspedal 6 is in maximum throttle position.If accelerator pedal 6 under continuing when maximum throttle position, acceleration cable 8 will cross flex point 4, and connecting lever 2 can apply a drop-down active role power to Das Gaspedal 6 under the effect of throttle extension spring 10 and acceleration cable 8, state as shown in Figure 2, now Das Gaspedal 6 is pressed on caging bolt 7, caging bolt 7 pairs of Das Gaspedals 6 play block, thus achieve the self-locking of Das Gaspedal 6, and make Das Gaspedal 6 be in maximum functional throttle.The unblock of Das Gaspedal 6 relies on return stampeding section 9 to realize, and when needing to unlock, what step on return stampeding section 9 stretches out Das Gaspedal 6 part.
In the present embodiment, consider that this application of installation is on combined harvester, combined harvester has again normal walking operation and harvest operation two states, also be provided with one end in the below of Das Gaspedal 6 and be hinged on throttle limit base 3 on combining Rack Body 1 upper surface, throttle limit base 3 has vertically-arranged and keeps flat two working positions.When operation normally walked by combined harvester, throttle limit base is in vertically-arranged working position, now its height is higher than the height of caging bolt 7, trespass in journey 6 times in Das Gaspedal like this, Das Gaspedal 6 first contacts with throttle limit base 3, under the block effect of throttle limit base 3, Das Gaspedal 6 self-locking can be prevented; When combined harvester harvesting operation, throttle limit base 3 is in and keeps flat working position, and now its height is lower than the height of caging bolt 7, and can't interfere Das Gaspedal 6, Das Gaspedal 6 also can self-locking smoothly.
When above-described embodiment is particularly applicable on combined harvester, when combined harvester is normally walked on highway, throttle limit base 3 is gone to vertically-arranged state, just normally can control throttle size by Das Gaspedal 6; When combined harvester is at harvest operation, throttle limit base 3 is gone to flat condition, then directly step on to maximum throttle place by Das Gaspedal 6, now Das Gaspedal 6 is locked, and chaufeur also need not continue accelerator pedal; When needing to unlock, step on return stampeding section 9 downwards with pin, Das Gaspedal 6 can unlock.
In above-described embodiment, position limiting structure is arranged on the below of Das Gaspedal, coordinates and realizes the self-locking of Das Gaspedal, in other embodiments during to cross the flex point of connecting lever at acceleration cable with Das Gaspedal block, position limiting structure also can coordinate with connecting lever block, also can realize the self-locking of Das Gaspedal.
Due to a kind of form that connecting lever is lever, its flex point is the lever hinged support of lever, in other embodiments, also can adopt the lever of linearity.
In above-described embodiment, return stampeding section is arranged on the lower end of Das Gaspedal, what be namely arranged on Das Gaspedal deviates from one end that power tramples end, return stampeding section and power trample the two ends of holding the Das Gaspedal hinge-point that is placed in, in other embodiments, the power that return force application structure also can be connected to Das Gaspedal for one end tramples the return bracing wire on end, by upwards pulling return bracing wire to apply torque reaction to Das Gaspedal, also can realize the unblock of Das Gaspedal.
In other embodiments, also throttle limit base can not be set, if during Das Gaspedal locking, Das Gaspedal unlocked by return force application structure.
The embodiment of combined harvester of the present invention: the foot pedal accelerator device comprising combining Rack Body and be arranged on combining Rack Body, the structure of foot pedal accelerator device as shown in Figure 1 and Figure 2, consistent with the structure of the combined harvester foot pedal accelerator device of above-described embodiment, its content does not repeat them here.
