The specific embodiment
Shown in Figure 1, a kind of Miniature ground sweeper of the present invention includes chassis of vehicle body 105, be provided with limit brush 17 at chassis of vehicle body, round brush 19 and round brush motor 18, driving wheel 16, trailing wheel 21, chassis of vehicle body top are equipped with the electric pushrod 103 of control round brush lifting and the limit brush electric pushrod of control limit brush lifting, are separately installed with round brush device of wear compensation 13 and limit brush wear compensation device 14 at two electric pushrods.Limit brush dustcollecting system 15 places the top of limit brush 17.Dustbin 2 places chassis of vehicle body 105 rear portions.Dustbin top and dust cleaning case 4 are fixing, are provided with a large garbage inlet 5 on the outer wall of dust cleaning case.Be disposed with resistance dirt Turbogrid plates 6 in the dust cleaning case 4 from bottom to top, dust suction filter 7, dust absorption fan 8 and shake dirt motor 9.
In embodiment illustrated in fig. 4,2.4 meters of the car body axial lengths of road-sweeper, wherein dust cleaning case 4 length are 81 ㎝.1.6 meters of heights of the carbody, dust cleaning case height are 80 ㎝, and the dust cleaning case height here refers to clear height, but not the setting height(from bottom) of dust cleaning case on car body.The dust cleaning case width is identical with width of the carbody.Adopt so large dust cleaning case structure, the airborne dust that produces when road-sweeper is worked can enter rapidly in the dust cleaning case and by high efficiency filter, and unlikelyly can hold any more because dust cleaning case is too little, causes the secondary pollution of environment.
The dustbin bottom is in cleaning or be closure state at ordinary times, bottom switching electric pushrod 10 position that remains retracted.When dumping rubbish, by lifting device dustbin is lifted, when rising to certain altitude, start bottom and open and close electric pushrod 10, the expansion link of push rod stretches out, and connecting rod 602 promotes flipping side 605 rotations two lids of dustbin bottom 1 are opened, and the rubbish in the casing is poured out rapidly by the bottom.Then start bottom and open and close the electric pushrod Closing Switch, two lids are resetted namely close the dustbin bottom.
The lifting device of dustbin mainly is comprised of the column 12 of dustbin elevating ram 22, lifting principal arm 11, registration arm 23 and ∏ shape structure, on two cylinders of column 12, respectively be hinged with a lifting principal arm 11 and a registration arm 23, the telescopic end of two dustbin elevating rams 22 is hinged with two lifting principal arms 11 respectively, and the other end of lifting principal arm 11 and registration arm 23 is hinged on the both sides of dustbin/dust cleaning case casing.Dustbin elevating ram 22 state that remains retracted at ordinary times, lifting principal arm 11 is received for 23 times with registration arm, dustbin/dust cleaning case is between two crossbeams of chassis of vehicle body, garbage inlet is that the airborne dust entrance is near round brush 19, there are weather strip 20 sealings the entrance both sides, guarantee that airborne dust all enters in the dust cleaning case in cleaning process.In the time of need to dumping rubbish, start dustbin elevating ram 22, the oil cylinder telescopic arm is with lifting principal arm 11 jack-up and drive dustbin/dust cleaning case and released and be increased to two openable height of lid by the chassis of vehicle body horizontal level, the dustbin bottom of this moment can be opened and dumps rubbish, or opens after being raised to correct position according to outside refuse container height.
Shown in Figure 2, road-sweeper of the present invention limit brush dust exhaust apparatus comprises the past case 310 that is fixed on the chassis of vehicle body, and dust absorption fan 301 before the rear wall of past case 310 is fixed with, and past case front portion is tiltedly installed with a front filter 304.Front filter anterior corresponding dust absorption passage 309.These dust absorption passage 309 tops link to each other with past case, bottom entering-dust mouth and limit brush are at a distance of 15-30 ㎝, the entering-dust mouth of dust absorption passage place limit brush 17 directly over, when the limit dataller does, start simultaneously limit brush dustcollecting system, dust absorption fan 301 generation negative pressure suck dust absorption passage 309 with airborne dust and after front filter 304 filtered, clean air was discharged by bellows 302.The dust that is collected at filter cotton/online during dust removal and filtration is more, thus vibrating motor 303 work before starting after work a period of time, the dust cleaning case that dust is shaken and drops down onto dust absorption passage and fall into the bottom.
Among Fig. 3, the chassis of vehicle body bottom is provided with the round brush assembly, by support brace 106, and round brush 19, regulating wheel 108, round brush adjustable plate 109, round brush motor 18 and belt 111 form.The device of control round brush lifting is electric pushrod 103.Be fixed with an adjustment seat 104 at chassis of vehicle body 105, electric pushrod 103 places in the adjustment seat, upper bottom surface central spot in adjustment seat 104 is shaped with an adjustment hole, adjusting screw(rod) 102 passes adjustment hole and enters in the adjustment seat 104, and the base 112 of electric pushrod 103 is fixed on the bottom of adjusting screw(rod) 2.Cover has a butterfly adjusting nut 101 on the top of adjusting screw(rod) 2, by adjusting nut 101 controllable adjustable screw rods 102 up and down so that the height of control electric pushrod 103, realized thus the purpose of round brush/limit brush bristle compensation.
Shown in Figure 5 is another embodiment of dust cleaning case 4, dust absorption fan 8 sides wherein, filter adopts V-arrangement filter cloth 427, and above-mentioned V-arrangement filter cloth is fixed on dust cleaning case top by a support 423 usefulness nuts, is fixed with vibrating grid 424 and shake dirt motor 9 on the top of V-arrangement filter cloth.For the wedge angle that prevents V-arrangement filter cloth 427 gathers dust, between the V-arrangement wedge angle at filter cloth back, be provided with circularoscillations bar 425.During work, can start at any time shake dirt motor 9, it will attach on the V-arrangement filter cloth by vibrating grid 424 and circularoscillations bar 425 and the dust of sharp corner shakes and drops in the dustbin of bottom in 2.
Shown in Figure 6 is that dustbin/dust cleaning case is at low level lifting state.
