Embodiment
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
As depicted in figs. 1 and 2, this hay mower comprises frame 1, road wheel 2, stationary knife 3 and hobboing cutter 4, frame 1 comprises baffle plate 1b and divides the framework lateral plate 1a being located at both sides, the front end of framework lateral plate 1a is provided with the straw basket 6 for splendid attire grass bits, the rear end of framework lateral plate 1a is connected with hand-pushing handle 7 and rear tugboat 8, two road wheels 2 points are located at mower both sides and are rotationally connected by the framework lateral plate 1a of main shaft 9 with corresponding side.
As shown in Figure 3, connect one to one with above-mentioned two road wheels 2 after the two ends of a cutter shaft 5 are each passed through the framework lateral plate 1a of frame 1 both sides, hobboing cutter 4 is arranged on cutter shaft 5.Stationary knife 3 between two pieces of framework lateral plate 1a, and is all fixed with stationary knife fixed head 10 at two, and described stationary knife fixed head 10 is fixed on the framework lateral plate 1a of corresponding side by securing member such as screw 11 grade, forms shear gap between stationary knife 3 and hobboing cutter 4.
Each stationary knife fixed head 10 is equipped with " U " shape adjustment seat 12 of one, this adjustment seat 12 is stretched out from the adjustment hole 13 corresponding side frame side plate 1a, and opening is just just to adjustment apertures 13.The medial surface of framework lateral plate 1a is also equipped with an adjustment flap 14, one end of flap 14 is regulated to be rotationally connected with framework lateral plate 1a by rotating shaft 15, the other end is provided with adjusting portion 16, and adjusting portion 16 is inserted in " U " shape adjustment seat 12 after the adjustment hole 13 framework lateral plate 1a stretches out.An adjusting rod 17 passes two sides of adjusting portion 16 and adjustment seat 12, and the two ends of exposing all are fixed with a limit screw cap 20, and limit screw cap 20 is resisted against in adjustment seat 12, and the middle part of adjusting rod 17 is threaded with adjusting portion 16.
As shown in Figure 4, the connecting hole 22 that flap 14 offers two arc guide grooves 21 and allows cutter shaft 5 pass through is regulated.In use procedure, the vibration of whole mower is frequent, be shifted in order to avoid regulating flap 14, some holding screws 23 can be arranged at gathering sill 21 place adjustment flap 14 and framework lateral plate 1a are tightened together, when needing to regulate shear gap, unclamp holding screw 23, holding screw 23 is due to the existence of arc guide groove 21, the adjustment action regulating flap 14 can not be hampered, after having adjusted, again screw holding screw 23.
As shown in Figure 5, road wheel 2 is provided with concentric inner ring gear 24, inner ring gear 24 is engaged with the less planetary gear of size 25, planetary gear 25 with through regulating the cutter shaft 5 of connecting hole 22 on flap 14 to be coaxially connected.When keeping regulating flap 14 position immobilizing, the connecting hole 22 of planetary gear 25 and the modulated flap 14 of cutter shaft 5 limit, and can only rotate in original place, so realize the shear action of hobboing cutter 4 under the drive of inner ring gear 24.
During use, gardener promotes the walking of whole mower by hand-pushing handle 7, road wheel 2 rotates in walking process and drives inner ring gear 24 together to rotate, and then driving the planetary gear 25 of engagement and cutter shaft 5 to rotate backward by inner ring gear 24, hobboing cutter 4 rotates with cutter shaft 5 and coordinates with stationary knife 3 and cut off by the green grass entering shear gap place.The grass bits cut are taken advantage of a situation by the hobboing cutter 4 rotated and are swept in the straw basket 6 in front, and the baffle plate 1b of frame 1 plays and prevents grass from considering the object flashed to be worth doing.
When needs regulate shear gap, first with instrument, the holding screw 23 etc. regulated on flap 14 is unscrewed, turn adjusting rod 17 again, the adjusting portion 16 of adjustment flap 14 is moved along adjusting rod 17, thus drive adjustment flap 14 to do circular motion centered by rotating shaft 15, be inconjunction with cutter shaft 5, hobboing cutter 4 and planetary gear 25 and together do circular motion, the shear gap between hobboing cutter 4 and stationary knife 3 is changed.In this process, road wheel 2 also needs to rotate certain angle to coordinate the change in location of planetary gear 25 around main shaft 9, the hole size in addition framework lateral plate 1a supplying cutter shaft 5 to pass and the motion needs of shape demand fulfillment cutter shaft 5.After adjustment completes, screw and regulate holding screw 23 on flap 14, for convenience of adjustment, can in the end opens of adjusting rod 17 hexagonal.
Because adjusting rod 17 is straight-bar, adjusting portion 16 also does circular motion while moving along adjusting rod 17 centered by rotating shaft 15, and circular motion is easily conditioned bar 17 and keeps off.For this reason, in the present embodiment, adjusting portion 16 is arranged on and regulates flap 14 as far as possible away from rotating shaft 15 place, and increased radius allows the side-play amount of adjusting portion 16 minimize.Meanwhile, make adjusting rod 17 and the tangent setting of movement locus of adjusting portion 16, impact is reduced to minimum.Moreover, perforation 18 aperture that adjustment seat 12 is passed for adjusting rod 17 can also be made comparatively to be greater than the external diameter of adjusting rod 17, to allow adjusting rod 17 realization deflection to a certain degree when regulating flap 14 to move.
As shown in Figure 6, the adjustable plate 28 that the rear end part of frame 1 is also provided with turning cylinder 26, bracing frame 27 and is fixedly connected with framework lateral plate 1a, adjustable plate 28 is hinged with and regulates spanner 29, bracing frame 27 is fixedly installed on turning cylinder 26, the two ends of described turning cylinder 26 are rotationally connected with the framework lateral plate 1a of both sides respectively, wherein one end is fixedly connected with regulating the articulated section of spanner 29 through after adjustable plate 28, above-mentioned contact to earth after tugboat 8 be arranged on bracing frame 27 by hind axle 19 rotation.
As shown in Figure 7, adjustable plate 28 is disposed on some chuck 28a, chuck 28a with regulate the pin joint of spanner 29 and adjustable plate 28 for the center of circle be that arc-shaped distributes, regulate on spanner 29 and offer the button hole 29a matched with chuck 28a, be provided with elasticity between adjustment spanner 29 and adjustable plate 28 and press part.
In lawn care process, for the growing way on different physical features and lawn, need to adjust cutting range in good time.Under normality, regulate spanner 29 press part effect by elasticity and be resisted against on adjustable plate 28, one of them the chuck 28a on adjustable plate 28 is inserted in the button hole 29a on adjustment spanner 29.When needs carry out adjustment cutting range, pull laterally and regulate spanner 29, overcome elasticity to press part chuck 28a is extracted out from button hole 29a, and rotate around pin joint under adjustment spanner 29 remains on flare state, drive turning cylinder 26 and bracing frame 27 to rotate simultaneously.Mower rear portion can be raised by the words that bracing frame 27 erects, if lie low and can reduce rearward height, the front and back in conjunction with hobboing cutter 4 and stationary knife 3 arrange relation, and the height achieving shear gap regulates change.After adjustment completes, the adjustment spanner 29 unclamped can be close to adjustable plate 28 automatically, and the chuck 28a of corresponding position is inserted in button hole 29a and completes locking.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
