Description

Mower

The utility model relates to a kind of mower that is used to cut the grass on a lawn, and especially a kind ofly is adapted at having the mower that uses in the lawn of barrier.

At present, resemble the median strip of highway and the lawn that the both sides of highway side slope has barrier like this, all adopt artificial method to prune, not only labour intensity is big for this method, inefficiency, and the effect of pruning is also undesirable, and the lawn is uneven, and is very not attractive in appearance.Although it is more to be used to the mower that cuts the grass on a lawn in the prior art, but the opening that often is only limited to clear in the lawn uses, as Granted publication number is that the utility model patent of CN2133128Y is disclosed a kind of by actuating unit, transmission case, hydraulic mechanism, the mower that knife rest constituted, it is power with the tractor, drive three oil pumps by control crank and set up separately independently three hydraulic circuits respectively, to satisfy three groups of knife rest cuttings, lifting, lock isobaric power-actuated needs, have easy and simple to handle, advantages such as swath face width and cutting force are strong, but also the method that can utilize hydraulic mechanism upwards to promote knife rest is hidden a small amount of shorter barrier in the process of advancing.However, this mower does not still satisfy the needs that the median strip that resembles highway and both sides of highway side slope have the turf-mown of barriers such as more fence post and road sign like this.

The purpose of this utility model is to provide to be used in a kind of lawn that is adapted at having barrier, and its cutter mower of avoiding barrier at any time in the process of advancing continuously, so that thoroughly solve a series of problems that manually cut the grass on a lawn and brought at present, the purpose that reach quick, neat to the greatest extent, mechanization cuts the grass on a lawn.

The purpose of this utility model is to realize like this, this mower comprises that mainly the motor vehicle that has hydraulic gear forms, connect a crossbeam to motor vehicle one side horizontal expansion in motor vehicle the place ahead, two hydraulic cylinders are installed on the crossbeam, connect a carriage on two hydraulic cylinders respectively, a gyrator is respectively installed in the lower end of each carriage, and is connected with cutter on the axle of gyrator.

Because former and later two carriages have constituted the straddle type structure in this mower equipment on crossbeam, and each carriage is done horizontal reciprocating motion at the effect lower edge crossbeam of hydraulic cylinder separately, therefore the utility model is in the process of mowing, when having guaranteed that motor vehicle longitudinally travels continuously, cutter gets around barrier in the lawn by the mode of back and forth shuttling back and forth under the drive of hydraulic cylinder, solve a series of problems that manually cut the grass on a lawn and brought, realized the purpose quick, neat, that mechanization cuts the grass on a lawn.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a front view of the present utility model;

Fig. 4 is the vertical view of Fig. 3;

Fig. 5 is the A-A enlarged drawing of Fig. 3.

As shown in Figure 1, 2, the utility model comprises that mainly the motor vehicle 1 that has hydraulic gear forms, connect a crossbeam 4 to motor vehicle one side horizontal expansion in motor vehicle 1 the place ahead, two hydraulic cylinders are installed on the crossbeam 4, connect a carriage 6,5 on two hydraulic cylinders respectively, a gyrator 61,51 is respectively installed in the lower end of each carriage 6,5, and is connected with cutter 8 on the axle of gyrator 61,51.

As shown in Figure 1, 2, the cross section of crossbeam 4 is " T " font, its both sides are installed a hydraulic cylinder (hydraulic cylinder 41 of the front of only having drawn among the figure) separately, each hydraulic cylinder all connects a slide block that is positioned on the T type crossbeam, former and later two carriages 6,5 are connected on the corresponding hydraulic cylinder by the slide block 43,42 of correspondence, cutter 8 connects (also can directly not connecting by cutterhead) on 61,51 of the gyrators of two carriages, 6,5 lower ends, front and back indirectly by cutterhead 62,52, and wherein the quantity of cutter 8 can be determined arbitrarily as required.

Shown in Fig. 3,4,5, contact with barrier and be damaged in the process of work for fear of cutter, the spring steel wire that cutter 8 employings of the present utility model have blade is made.In addition, also can adopt flexible resilient material such as nylon to make.

As shown in Figure 1, 2, under the prerequisite that the front end of guaranteeing crossbeam 4 does not bump with barrier, the utility model is by the mode that the lower end of front rack 6 is outwards stretched its brachium that extends, so that provide condition for the cut coverage that enlarges cutter.

As shown in Figure 2, gyrator 61,51 front and back before and after the utility model on two carriages certain distance that staggers, be installed in cutter (radius that should comprise cutterhead when the connecting indirectly) moderate length on the two gyrator axles simultaneously, can not be long, can not be too short, its condition is: when front and back two carriages nearest, two groups of cutters do not contact in the process of rotation mutually before and after should guaranteeing; When the distance of front and back two carriages farthest the time, two groups of cutters are in rotary course before and after should guaranteeing, its cut coverage slightly repeats.

As shown in Figure 1, 2, apart from no-load running, the utility model is installed a crane 2 in the place ahead of motor vehicle for the ease of long, is fixed with a pair of ear seat 31 in a side of crane 2, by bearing

32,33 and ear seat 31 crossbeam 4 is connected on the crane 2.Be duty shown in the figure, during the no-load running state, bearing pin 33 extracted out, simultaneously crossbeam 4 is horizontally rotated 180 ° around axle 32, again bearing pin 33 is inserted in the hole 311 of ear seat 31.

As shown in Figure 1, 2, reverse driving during for fear of the side slope of pruning both sides of highway, the utility model is installed a crane 2 in the place ahead of motor vehicle, center and both sides at crane 2 are fixed with three pairs of

ear seats

24,25,22 that are positioned at sustained height, ear seat 24 in the middle of being positioned at is connected with an end of a support arm 3 by bearing pin 23, match with an ear seat 22 in the both sides by bearing pin 21 again support arm 3 is fixed on the crane 2, on the vertical plane of support arm 3 other ends, be fixed with a pair of ear seat 31, crossbeam 4 be connected on the support arm 3 by bearing
