Embodiment

It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched The embodiment stated is part of the embodiment of the present utility model, rather than whole embodiments.Based on the reality in the utility model Apply example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made, all Belong to the scope of the utility model protection.

As depicted in figs. 1 and 2, the utility model includes vehicle body 1, the collecting box 2 being located on vehicle body 1, is connected to collecting box 2 On vacuum extractor 3, the collection cover 4 that is connected with collecting box 2, pass through some breather pipes 41 between collecting box 2 and collection cover 4 Connected, collection 4 lower ending openings of cover.The utility model also includes first straight line guiding assemblage, mounting bracket 6, lifting device 7 and control Device processed, mounting bracket 6 are vertically slidably connected at through first straight line guiding assemblage on collection cover 4, first straight line guiding assemblage Including the first guide rail 5, the first sliding block 51 and the first driver, the first guide rail 5 is connected on mounting bracket 6, and the first sliding block 51 is fixed In collection cover 4, the first guide rail 5 is connected on the first sliding block 51, and the first driver is used to drive the first sliding block 51 and first to lead Relative motion between rail 5, the first driver are connected with controller.Mounting bracket 6 is connected with an at least lifting device 7, and lifting device 7 is logical Bolt group 78 is crossed to be removably attachable on mounting bracket 6.

As shown in Figures 2 to 4, each lifting device 7 respectively includes plate 71, second straight line guiding assemblage, some combing bars 74 and some bar balladeur trains 75, comb the cross section of bar 74 includes the second guide rail 72, second for circle, second straight line guiding assemblage The driver of sliding block 73 and second, the second driver are used to drive the relative motion between the second sliding block 73 and the second guide rail 72, the Two drivers connect with controller.In same lifting device 7, the second guide rail 72 is located on plate 71 along the longitudinal direction, and second Sliding block 73 is slidably connected on the second guide rail 72, and lifting device 7 is respectively provided with some combs in the opening position at left and right sides of sliding block Bar 74 and some bar balladeur trains 75 are managed, each the inner for combing bar 74 is respectively hinged on the second sliding block 73, and each combing bar 74 is each A bar balladeur train 75 is combined with, bar 74 is combed and is slidably connected on the bar balladeur train 75 coordinated with the combing bar 74, each bar balladeur train 75 It is rotatably connected on respectively on plate 71.Bar balladeur train 75 includes rotating turret 751, the first rod 752 and the second rod 753, rotating turret 751 are rotatably connected on plate 71, and the first rod 752 and the second rod 753 are rotatably connected on rotating turret 751 respectively, and first The side of rod 752 and the side of the second rod 753 are pressed on the side that bar 74 is combed corresponding to the sliding rod frame respectively.This reality Also include the first proximity switch 76 and the second proximity switch 77 with new, the first proximity switch 76 and the second proximity switch 77 are distinguished It is located on the second guide rail 72, the first proximity switch 76 is located at the front side of the second sliding block 73, and the second proximity switch 77 is slided positioned at second The rear side of block 73, the first proximity switch 76 and the second proximity switch 77 electrically connect with controller respectively.

As shown in Figures 1 to 5, the utility model in the course of the work, the dynamic of the first driver is controlled by controller Make, and then control the lifting of mounting bracket 6, and then control the height of lifting device 7, and then control the height for combing bar.Pass through control Device controls the action of the second driver, and then controls between the second sliding block 73 and the second guide rail 74 relative motion, passes through sliding block 73 slidably reciprocating to realize the opening of combing bar and pack up on the second guide rail 74.

When the leaf on lawn is located at using the utility model cleaning, under the using of vacuum extractor 3, collect Negative pressure is produced in case 2, in the presence of this negative pressure, the lower ending opening of the acquired cover 4 of leaf is inhaled into collecting box 2, from And realize the collection work of leaf.When cleaning, reaching combing bar 74 can pass through at the height of thick grass.Then vehicle body 1 advances, and preferably interts in order that combing bar 74 in the gap of thick grass, and for vehicle body 1 when advancing, each bar 74 that combs is in such as Collapsed state shown in Fig. 5, bar 74 is combed in collapsed state, comb 74 oblique front of bar and set.Then vehicle body 1 moves ahead, when When collection cover 4 advances to next purging zone with vehicle body, comb the collapsed state shown in bar from Fig. 5 and change to such as Fig. 4 institutes The open mode shown, bar 74 is combed in open mode, comb bar and set in left-right direction, then combing the open mode of bar Under, controller controls the action of the first driver, combs bar 74 and is pumped in thick grass, so as to be covered by careless strain, blade of grass The leaf for covering or linking separates from thick grass, so as to which the leaf on lawn thoroughly be cleaned out in the very first time, meanwhile, When combing bar is changed to open mode by collapsed state, combing bar can also stir to thick grass, be able to can also incite somebody to action The leaf for being linked or being covered by careless strain, blade of grass separates from thick grass.Structure of the present utility model not only can be by leaf from grass Separated in clump, but also the damage to thick grass can be reduced, avoided blade of grass from breaking to fall from careless strain, keep the integrality on lawn.

The circular in cross-section of bar is combed, this, which can be reduced, combs bar to careless strain or the scuffing of blade of grass, further protects Demonstrate,prove the integrality on lawn.

Second sliding block 73 can preferably be controlled by the first proximity switch 76, the second proximity switch 77 and controller Position on two guide rails 72, preferably control combs the folding and unfolding of bar, so as to ensure that work of the present utility model is more smooth.

When combing bar 74 and being slided on bar balladeur train 75, the first roller 752 and the second roller 753 can ensure this The smooth degree slided, because working environment of the present utility model is thick grass, has the broken leaf in part or careless strain is extruded To the first roller 752 and the tangent opening position of bar 74 is combed, or is extruded to the second roller and combs the tangent position of bar 74 Place, because when combing bar 74 while being slided on bar balladeur train 75, the first roller and the second roller can rotate simultaneously, in the first roller Under the rotary action of son and the second roller, these broken leaves being extruded or careless strain can timely be fallen down, so as to avoid Slip of the bar on bar balladeur train is combed to impact.Meanwhile first roller 752 and the second roller 753 can also play and avoid combing The effect that the side of reason bar is scratched, because the side for once combing bar is scratched, it is sliding on balladeur train not only to influence combing bar Dynamic smooth degree, and cut than it is more serious when, comb bar on cut careless strain or blade of grass may be caused Incised wound, so the first roller 752 and the second roller 753 also act as the effect on protection lawn to a certain extent.

Lifting device 7 is removably attachable on mounting bracket 6 by bolt group 78, and this can facilitate examines to lifting device Repair.
