Description
The utility model relates to a kind of pair of charging aperture spreading machine for pavement substrate, is mainly used in road surface base layer material is evenly entirely paved on the ground.
As everyone knows, present road surface base layer material is laid, and except that adopting manually, also adopts land leveller, bulldozer etc. to pave, and this mode subject matter is inefficiency, poor flatness.When adopting asphalt paver to pave, subject matter is the equipment price costliness, and the another one problem is that equipment attrition is serious.
A kind of paver that China Patent No. " 99115805.9 " " 99115897.0 " proposes is quoted the land leveller principle, and subject matter is that structure is comparatively complicated, and cost is higher relatively.The another kind of paver that China Patent No. " 93108953.0 " proposes, quote the ironing plate of asphalt spreader principle, behind screed, be provided with one and press muller, the problem of this scheme is press to grind operation not resemble the asphalt paver in dull and stereotyped the place ahead but because structural limitations can only be located at the screed rear, press the raising of grinding the back planeness to be very limited like this, this scheme practical effect also illustrates, adds to press behind the muller planeness not improve to greatly reduce on the contrary.Be exactly that this scheme weight is excessive in addition, complex structure is because drive not itself is used quite inconvenience.In addition, the problem of above-mentioned several schemes also has paving width too narrow.
The purpose of this utility model provides a kind of pair of charging aperture spreading machine for pavement substrate, and it has the following advantages: (1) is simple in structure; (2) in light weight; (3) easy to use; The planeness height; (5) paving width is big.
For achieving the above object, a kind of pair of charging aperture spreading machine for pavement substrate that the utility model proposes is such: the both sides at a support assembly of being made up of two groups of pushing tow rollers, crossbeam, support wheels respectively are provided with a height adjustable sliding guide sleeve.Cover lower end and support assembly are hinged in this sliding guide sleeve, and articulated manner is for swinging, and the sliding guide sleeve overcoat then is connected with the promotion side arm, and slip between the interior outer bush and difference in height adjustment are realized by the hydraulic jack that is placed in one; Above-mentioned promotion side arm extands rearward to dozer both sides and affixed with dozer, and this dozer lower plane is plate, and this flat board fore-and-aft direction length can be 40-80 centimetre, generally make with high-abrasive material, and available bolt is connected on the dozer.Directly be placed on the scope of operation during operation.Form between frame and the dozer left and right sides width be about short greater than the wide front and back of two dump trucks, about long feeder hopper type open slot.The dozer rear portion is equipped with the power source of adjusting oil cylinder: oil pump-engine system, the dozer afterbody is provided with a linkage, this linkage is used for installing different model and promotes machinery, crawler dozer commonly used is particularly suitable for, like this, when linking to each other with dozer by linkage, bulldozer promotes dozer forward, dozer then promotes frame by promoting side arm by sliding guide sleeve, and then advance by two dump trucks that the pushing tow roller on the frame promotes the front, these two dump trucks are to pour material on the ground of the funnel type open slot that forms between frame and the dozer into while walking, the material that enters under the dozer is shakeout by dozer, and the material of dozer front portion presses to the both sides certain width by dozer and paves.
Enter material under the dozer what by the angle of elevation alpha decision of dozer lower plane, it is just many that the elevation angle greatly then enters under the dozer material, on the contrary the material that the elevation angle is little then to be entered below the dozer is just few, and then decision shop layer thickness.The change of dozer angle of elevation alpha then realizes that to change promotion side arm leading portion height the power source of oil cylinder is then provided by the oil pump-engine system behind the dozer by the variation of oil cylinder height in the sliding guide sleeve.
Above-mentioned funnel type open slot left and right directions width is generally 5-7 rice by general dump truck double-width.
Above-mentioned two groups of pushing tow rollers can be directly installed on the frame, also can be installed in certainly on two pushing tow turning rollss, and each pushing tow turning rolls and housiung separator are hinged, and the pushing tow turning rolls can be swung on horizontal plane around pin joint.
For making the turning to of paver can be with promoting turning to and adjusting of machinery, the wheel carrier front portion that support wheel can be set to support wheel be hinged by a vertical shaft and crossbeam, thus formation everything wheel construction.
For preventing in two dump truck batch turning processes frame and dozer to be produced unbalance loading, support wheel can be arranged to the structure that hydraulic control turns to.
Above-mentioned dozer for material is pressed to both sides smoothly, can be arranged to dozer minor face isosceles trapezoidal structure forward except that itself paves material.
When dozer presses to two rear flank with material, for reaching certain paving width, can an additional stops be set in the dozer both sides, be used for material is wipeed off.
Certain above-mentioned additional baffle plate can be arranged to adjustable, and regulative mode can be the door leaf formula, also can be bolt and connects.
The motor of the oil pump-engine system of dozer back can adopt the motor that has clutch to be beneficial to start.
Several porous junction plates of the linkage that the dozer tail end face is provided with are used for installing the connector that is connected with bulldozer.
The linkage of dozer afterbody can directly place the dozer tail end face.
Certainly, above-mentioned linkage also can be arranged on the rear end face of a connector that is hinged with the dozer afterbody, and the jointed shaft of this connector and dozer is that horizontal pin is gone into, when the side is seen, but free bend between connector and the dozer.
Be the low crown of pavement requirement in high both sides in the middle of adapting to, about flat board under the dozer can being arranged to two, two avris of two flat boards are hinged with dozer respectively about this, also be hinged between two flat boards, be provided with between middle hinge place and the dozer one regulate about the adjusting device of angle between the flat board, this adjusting device is generally the screw type structure.
In sum, a kind of spreading machine for pavement substrate that the utility model proposes has following advantage: (1) itself carries motor, and is easy to use; (2) simple in structure, in light weight, with low cost; (3) planeness is easy to adjust accurately; (4) promoting mechanical link succinctly makes things convenient for; (5) paving width is big.
Be further described below in conjunction with accompanying drawing.
