Be connected by bolt between described casing 17 and the frame 18.
Below in conjunction with a description of drawings use of the present invention:
Before the use, regulate cutting-height earlier and push rod is adjusted to suitable position.
As Fig. 1～shown in Figure 6, when regulating cutting-height, because front-wheel 22 is supported on ground, rotate the handle 23 of turning handle 15, turning handle 15 height can rise or descend, and the casing 17 that is connected with turning handle 15 also changes along with turning handle 15 change in location, and frame 18 positions that are fixed on casing 17 bottoms change thereupon, therefore the upper cutter 21 that is connected frame 18 front ends is highly regulated with following knife section 20, and namely cutting-height is regulated.Because the distance between 14 of internal thread bar 28 and the road wheels is greater than the cutting-height adjustable range, so the angle on upper and lower knife section and ground remains unchanged substantially.
As Fig. 1, Fig. 3, Fig. 4, Fig. 7～Figure 11 and shown in Figure 15, regulate transfer bar mechanism 54 to the method for correct position: the pin button mechanism 9 between king-rod 8 and lower beam 10 is in the lock state, be that springs 13 in the pin 11 are when being in release conditions, spring 13 ejects pin 11, match with shoulder hole 61 until it, at this moment, the gear teeth 57 of pin 11 are meshed with the gear grooved 56 of king-rod 8 and the gear blind hole 60 of pin support 12 simultaneously, king-rod 8 can't rotate, and namely king-rod 8 is with respect to pin support 12 fixed-site.Pin button mechanism 9 between king-rod 8 and lower beam 10 is in adjustment state, and when namely the spring 13 in the pin 11 was in compressive state, the gear teeth 57 of pin 11 only were meshed with the gear blind hole 60 of pin support 12, and at this moment, king-rod 8 can freely rotate around pin 11.In order to reach the purpose of quick cooperation, can be at the arranged outside dial of pin support 12, by observing the dial adjusting angle.When king-rod 8 turns to proper angle, for example 30 ° the time, unclamp pin 11, spring 13 ejects pin 11, pin 11 gear teeth 57 are meshed with the gear grooved 56 of king-rod 8 and the gear blind hole 60 of pin support 12 simultaneously, king-rod 8 is namely fixed, and at this moment, king-rod 8 is finished with the angular adjustment of lower beam 10.Because the second pin button mechanism 65 is identical with the principle of pin button mechanism 9, lower beam 10 is adopted the adjusting that uses the same method with the angle of casing 17, namely regulates pusher grip 1 height off the ground or folding transfer bar mechanism 54.
As Fig. 7 and Figure 12～shown in Figure 14, when pressing 5 times positioning convex 48 of backstay, button 51 is depressed, and upper boom 2 is relative with king-rod 8 positions movable, and at this moment, upper boom 2 can move axially along king-rod 8, transfer bar mechanism 54 can be drawn in.During work, when upper boom 2 is drawn out to the extreme higher position, button 51 ejects from king-rod locating hole 7, to push up the following positioning convex 48 of backstay 5 simultaneously, backstay 5 rotates, the last positioning convex 46 of backstay 5 is pressed on the upper boom 2 in the hole 3, and namely by button 51 and backstay 5 lockings, upper boom 2 is with respect to king-rod 8 fixed-site simultaneously in upper boom 2 positions.
As Fig. 1～shown in Figure 4, during use, by promoting pusher grip 1 lawn mower of the present invention is moved ahead, in advancing, road wheel 14 rotates and drives 14 rotations of road wheels, and by the be increased rotating speed of 35 of second gears of the transmission between first gear 33 and second gear 35.The crank 38 that is fixed on 35 of second gears rotates with 35 of second gears and drivening rod 39 motions, the other end of connecting rod 39 is connected with poke rod 40 hinges, the two can relatively rotate, because poke rod 40 lower ends are arranged in the guide rail of rocking bar guide rail pole 41, make it can only be perpendicular to rocking bar guide rail pole 41 along guide rail movement, therefore, connecting rod 39 1 ends that link to each other with poke rod 40 finally can only move at the straight line parallel with frame 18.Rocking bar guide rail pole 41 is fixed in the rocking bar rotating shaft 42 with 90 ° of angles with rocking bar poke rod 43, and rocking bar rotating shaft 42 is arranged in the rocking bar shaft hole of frame 18, and is free to rotate.Drive 30 motions of knife section guide rail pole when being arranged on the interior driving lever 29 of rocking bar poke rod 43 through holes with 43 motions of rocking bar poke rod, knife section guide rail pole 30 is fixed on the upper and lower knife section, the driving lever 29 of stirring upper cutter 21 directly is connected with the knife section guide rail pole 30 of frame 18 tops, stirs down the driving lever track hole 50 that the driving lever 29 of knife section 20 need pass on the frame and is connected with the knife section guide rail pole 30 of frame 18 belows.Upper and lower knife section is arranged on frame 18 front ends by upper and lower pressuring blade device respectively, can move along upper and lower groove respectively.Therefore endplay device can be converted into the reciprocating motion of toggle on the lawn mower direction of advance upper and lower knife section perpendicular to the reciprocating motion on the direction of advance, makes upper and lower knife section to carry out and cuts grass.Because both sides crank 38 is parallel to each other, the upper cutter 21 when therefore working is just in time opposite with following knife section 20 directions of motion.
