Abstract
The utility model discloses a balance device of a lawn mower, which comprises a draw bar, a first connecting plate, a second connecting plate and a tension spring, wherein the first connecting plate is articulated with front wheels of the lawn mower by a front articulated shaft, and the second connecting plate is articulated with back wheels of the lawn mower by a back articulated shaft; one end of the draw bar is articulated with the first connecting plate by a front hinge pin and the other end is articulated with the second connecting plate by a back hinge pin; both ends of a front shaft of the lawn mower are symmetrically provided with elastic buffer gears, both ends of which are respectively connected with a housing and the front shaft of the lawn mower. The balance device of the lawn mower has simple structure and convenient operation. The upturned moment generated by tensile force causes an original turnup front wheel to move upwards, thus realizing the landing of the four wheels and reaching a new balance.
Description
Technical field
The utility model relates to a kind of hay mower, and especially a kind of bascule of hay mower belongs to the graden machine technical field.
Background technology
Along with the growth in the living standard and the needs of beautifying the environment, no matter usable floor area rapid growth in lawn is municipal administration, residential quarters or football field, golf course or the like, and lawn maintenance work is doubled and redoubled.Hay mower plays an important role in lawn maintenance work as greening installation.The mowing height of mower is decided by the liftoff distance of cutter, normally used mowing height adjustment mechanism is to regulate by the handle of heightening that is installed in the wheel side, rotate regulating handle during adjusting, the handle downside and the position of engagement that is fixed on the sector rack on the case are heightened in adjustment, thereby regulate the height of the ceding of Taiwan apart from ground, but, variation has taken place in the relative altitude by the ceding of Taiwan and front and back wheel shaft behind the handle adjustment ceding of Taiwan height, the common four wheels in front and back is easy to generate three wheels and lands, the phenomenon of a liftoff perk of front-wheel, cause when promoting the hay mower mowing, fuselage tilts, rock, unstability, hay mower is carried out difficulty, not only influences the pruning quality on lawn, also has potential safety hazard.
The utility model content
The purpose of this utility model provides hay mower bascule a kind of simple in structure, easy to operate, and this device can be regulated the balance of complete machine automatically after regulating the mowing height.
The utility model is achieved by the following technical programs:
A kind of hay mower bascule, comprise pull bar, first connecting plate, second connecting plate, described first connecting plate is hinged by the front-wheel of preceding jointed shaft and described hay mower, and described second connecting plate is hinged by the trailing wheel of back jointed shaft and described hay mower; One end of described pull bar is hinged by preceding bearing pin and described first connecting plate, and the other end is hinged by rear pin shaft and described second connecting plate; The front axle two ends of described hay mower are provided with elastic buffering mechanism symmetrically, and the two ends of described elastic buffering mechanism are connected with front axle with the hay mower case respectively.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid a kind of hay mower bascule, wherein said elastic buffering mechanism comprises the extension spring that connects horizontal side of case and front axle one end, one end hook of described extension spring is connected on the case of hay mower, and other end clasp joint is on the front axle otic placode of hay mower.
The utility model is simple in structure, and is easy to operate.When heightening the ceding of Taiwan apart from the height on ground with handle, rotating counterclockwise of first connecting plate, driving second connecting plate by pull bar rotates counterclockwise, case is moved to the front upper place of front-wheel, being connected extension spring between case and the front axle is subjected to the tension that case moves forward and extends, the resupinate moment that this pulling force produces moves up a front-wheel of perk originally, thereby realizes that four wheels all lands, and reaches new balance.In like manner, when turning down the ceding of Taiwan apart from the height on ground with handle, under the Flexible Reset power effect of extension spring, case moves to the back lower place of front-wheel, because the direction of gravity is identical with the direction of extension spring elastic force, makes that to turn down operation more easily laborsaving.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Fig. 2 is the front and back wheel connection diagram in Fig. 1 left side;
Fig. 3 is an extension spring extended state schematic diagram of the present utility model;
Fig. 4 is the I portion enlarged drawing of Fig. 3;
Fig. 5 is a perspective view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 5, the utility model comprises pull bar 1, first connecting plate 2, second connecting plate 3, two extension springs 4; First connecting plate 2 and second connecting plate 3 are the set square structure, and first connecting plate 2 is hinged with the front-wheel 14 of hay mower by preceding jointed shaft 21, and second connecting plate 3 is hinged with the trailing wheel 13 of hay mower by back jointed shaft 31.Pull bar 1 is a bow-shaped structural, the one end is hinged by the preceding bearing pin 23 and first connecting plate 2, the other end is hinged by the rear pin shaft 33 and second connecting plate 3, like this, pull bar 1 just couples together front-wheel 14 and trailing wheel 13 by first connecting plate 2, second connecting plate 3, the front and back four wheels of mower can be linked.The lower end of regulating handle 12 and second connecting plate 3 are hinged by bearing pin 32, when regulating handle 12 rotates, drive L shaped winning in succession and 16 rotate around bearing pin 32, make 3 rotations of second connecting plate, by pull bar 1, first connecting plate 2 front-wheel 14 and trailing wheel 13 are moved up and down synchronously.
As shown in Figure 3, heighten the ceding of Taiwan and ground apart from the time, pull regulating handle 12 counterclockwise, the lower end of regulating handle 12 turns to new position after sector rack 15 on the case 11 breaks away from engagement with being fixed on, drive L shaped connecting plate 16,3 rotations of second connecting plate, and first connecting plate 2 is rotated by pull bar 1, make front-wheel 14, trailing wheel 13 move down synchronously as shown in phantom in Figure 3.When turn down the ceding of Taiwan and ground apart from the time, pull regulating handle 12 clockwise, the linkage process of front-wheel 14, trailing wheel 13 as hereinbefore, front-wheel 14, trailing wheel 13 moves synchronously.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
