Abstract

The utility model relates to a sand return machine for sand road maintenance, composed of a sealing frame (2) supported by two wheels, a sand return machine (10) and a sand combing machine (15). The utility model is characterized in that the sand return machine (10) and the sand combing machine (15) are fixed on the four-connecting rod mechanism of the inner side of the sealing frame. The thickness of the sand return layer can be conveniently adjusted through the adjustment of the mechanism. Sand return and sand combing processes can be once accomplished by the machine. The work efficiency is obviously raised. Compared with manual sand return, the efficiency is raised by more than forty one time. Moreover, a dynamic dust removal means is not required, and thus, the dust pollution status can be reduced. Approximate 70% of flying dust can be recycled. The machine has the advantages of simple structure, convenient maintenance, low failure rate and much lower manufacturing cost.

Description

Sand return machine for sand road maintaince

The present invention is the equipment that highway maintenance is used, the particularly sand highway maintenance invention of sand sweeping equipment.

The sand mode of returning that prior art medium sand God in charge of the Earth road maintenance is used, what major part adopted all is the comb sand homogenizing device and artificial way of combining of motor traction, the sand sweeping equipment of doing in the past has plenty of installs two driving drums in the middle of frame, two conveyer belts are installed on cylinder, on conveyer belt, fixing sand-back device, another kind is the sand sweeping equipment of disc type, sand-back device is installed on disk is reached back Grains.Because this machine complex structure, it is little to return the sand effective width, and what take is to force transmission, and the dust sandstone flies upward terrible, and environment pollution is serious, so result of use is unsatisfactory.

Task of the present invention is in order to provide a kind of simple in structure, high efficiency, the highway maintenance sand sweeping equipment that minimizing is polluted.This sand sweeping equipment can be adjusted back sand thickness easily, returns sand comb sand two procedures and once finishes, and greatly reduces the situation of the contaminated environment that stirs up a cloud of dust.

Task of the present invention can realize by following measure:

It is the frame (2) by the two-wheeled supporting, sand-back device (10), sandstone combing device (15) is formed, it is characterized in that sand-back device (10), sandstone combing device (15) is fixed on the framework (4) of a quadric chain, connecting rod (3) one ends and frame (2) hinge joint, the hinge joint of the other end and framework (4) front end, soft connecting rod (16) (can be a wire rope, iron chains or non-metal rope) end is connected with framework (4) rear end, the other end of soft connecting rod (16) is connected with frame (2), formed quadric chain, determined back sand layer thickness by the length of regulating soft connecting rod (16).

Because the bar in the quadric chain of the present invention is soft connecting rod, so it is easy especially to regulate back sand thickness, when mixing up thickness simultaneously almost the total weight of framework all act on the sand layer of highway pavement, it is higher to return sand efficient, simultaneously owing to take simple and reliable quadric chain, sand-back device can be arranged arbitrarily and be unrestricted, thereby can take segmentation to return sand, select for use best angle to improve back the operating efficiency of sand, fabricating cost can reduce greatly, equipment failure rate also obviously reduces, and this machine can improve 40 times of work efficiency with artificial time sand comparison, because the frame of sealing has been taked in this invention, stir up a cloud of dust so limited, controlled the air pollution situation effectively, helped improving the operating efficiency of sand sweeping equipment, reclaiming airborne dust can be about 70 percent.

Figure has described a most preferred embodiment of the present invention.

Fig. 2: the vertical view of sand sweeping equipment

Fig. 3: the left view of sand sweeping equipment

Below in conjunction with accompanying drawing embodiment is described in detail:

Fig. 1 has described sand sweeping equipment, it has wheel (5) supporting frame (2) in known manner by axletree (13), pull round mechanism (1) and be hinged on the front portion of frame (2), and can in horizontal plane, rotate with respect to frame (2), connecting rod (3) one ends and frame (2) hinge joint, the hinge joint of the other end and framework (4) front end, wire rope (16) is fixedlyed connected with framework (4) rear end, the other end of wire rope is fixedlyed connected with cylinder (17), has formed quadric chain like this.Sandstone combing device (15) is fixed on the framework by bolt, adjusting pad (8), and soft skirt section (7) form enclosed construction by screw in frame lower and ground.Fore-stock (9) is hinged on frame (2) front, and can rotate in vertical plane, and when parking, swinging mounting contacts with ground, sand sweeping equipment can be parked.

Fig. 2: sand-back device (10), (11), (12) are to become 35-55 ° of angle by the front end of bolt fixed interval in framework (4) with the frame central line, form segmentation and returned the sand structure, seal cover (14), (19), (6) are by being bolted to the top of frame, with the sealing of frame upper end, cylinder (17) is by being bolted on the frame, shake the length that handle (18) can be regulated wire rope (16), thus the convenient sand thickness of regulating back.

Fig. 3: seal cover (20) seals on frame and with the frame front/rear end by screw, thereby has avoided fully stirring up a cloud of dust.
