Description
Technical field
The utility model relates to a kind of chippings spreader that is used to pave the way, and specifically, it is that a kind of dump truck is carried out the formula chippings spreader.
Background technology
In prior art, Chinese patent ZL02224914 provides a kind of " pushing-type spreader of bulk materials ", it comprises frame, be located at receiving hopper on the frame, be located at the distributing roller in the receiving hopper, the bin gate that is located at the receiving hopper bottom and the governor motion of bin gate, the bin gate of this technology is made of material toggling roller that is located at double as walking under the frame and the limit flitch that is located at material toggling wheel both sides, the side of rolling on, form discharging opening between material toggling roller and the limit flitch, by adjusting the size that two limit flitch folding degree can be regulated discharging opening.
The bin gate of this spreader has adopted the bin gate structure one time, and this bin gate structure fails to form the jogging of discharging preferably path between bin gate and material toggling, cause spreading inhomogeneous easily.Moreover, the thickness of spreading can only lean on this single bin gate to control, the thinner thickness of spreading if desired, the bin gate aperture will be transferred lessly, and in this case, spreader just requires higher to the uniformity of aggregate chips granular size, if there is bigger particle in the material, be easy to form the bin gate jam, not only influential to the uniformity of spreading, but also may cause damage to the bin gate and the transmission mechanism of spreader.In addition, the width of this spreader spreading can only be widened on the basis of frame width, and can not dwindle in the frame width range, and therefore, it can not finish the less spreading of width.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming in the prior art, provide a kind of spreading evenly, strong and can be implemented in the dump truck that the spreading reduced width is adjusted in the frame width range and carry out the formula chippings spreader to the inhomogeneities compliance of material.
For achieving the above object, solution of the present utility model is as follows:
It has a frame, the frame below is provided with road wheel, frame is provided with receiving hopper, in receiving hopper, be provided with a horizontal distributing roller, its special character is: the axle of described distributing roller links by chain drive and clutch and live axle, connect a pair of Wheel gripping device that links with dump truck of being used at the tail end of frame, be provided with the manually-operated platform in the front portion of frame; Be provided with a bin gate and a bin gate governor motion in the bottom of receiving hopper, a described bin gate is arranged side by side along the frame transverse horizontal by a plurality of segmentation drawing and pulling type bin gate structures and constitutes, and a described bin gate governor motion constitutes by driving the hand screw governor motion that slides before and after each segmentation drawing and pulling type bin gate; Below a described bin gate, be provided with secondary bin gate and secondary bin gate governor motion, described secondary bin gate constitutes with vertical striker plate with the horizontal positioned opposite of this material toggling roller along the material toggling roller of frame lateral arrangement by one, described secondary bin gate governor motion is made of the threaded adjusting mechanism that moves forward and backward of material toggling roller, and described material toggling roll shaft links by chain drive and sub-material roll shaft.
Above-mentioned vertical striker plate laterally is arranged side by side along frame by a plurality of segmentation striker plates and constitutes, and each segmentation striker plate all has elastic displacement self-adjusting mechanism separately.
The circumferential surface of above-mentioned material toggling roller is provided with the axial fin of uniformly-spaced arranging, and is used to force material toggling.
Be provided with the support wheel of a frame below frame front, this support wheel is installed in a vertically wheel hack lever lower end of telescopic adjustment, and the described hack lever bottom of taking turns connects firmly on frame, and the manually-operated platform is stretched out on its top, and adjusting handle is housed in the top.
In receiving hopper, be provided with a descending formula material guide strip on the position relative with distributing roller.
By above-mentioned solution as can be seen, this spreader has adopted upper and lower two adjustable secondary bin gate structures, by the relative adjustment of upper and lower two bin gates, can between bin gate and material toggling, form the jogging of material discharging preferably path, thereby strengthen the spreading uniformity.If the uniformity of material is bad, can suitably transfer a bin gate big, come thickness limited with the secondary bin gate, like this, when bulk materials flows to the secondary bin gate by a bin gate, step down, also can pass through the secondary bin gate through the pressure material toggling of material toggling roller and the elasticity of vertical striker plate, can not form the bin gate jam, make this spreader possess stronger adaptive capacity the inhomogeneities of material.Moreover a bin gate of this spreader has also adopted segmentation structure, and it can sequence closing, thereby is implemented in the width that dwindles spreading in the frame width.
