Description
Technical field
The utility model relates to a kind of chain-drive mechanism, in particular to a kind of centre of sprocket is away from adjustable chain-drive mechanism.
Background technique
Cold recycling on spot of asphalt pavement has become China to the main side of asphalt concrete road maintenance and renovation at present
One of method.Cement or lime are as a kind of additive, it is necessary to equably be spread on road surface in advance, it is necessary to carry out powder spreading
Operation.Secondly, in highway construction, frequently with stable native reinforcement roadbase and underlayment, lime, cement and Industry Waste ground-slag
Equal powders are the important components for stablizing soil.The spreading of above-mentioned powder is the important operation together before stabilized soil road construction, powder
Whether material is dispensed uniformly, directly affects and stablize the native mix uniformity, be related to the construction quality and service life of highway, powder is spread
Cloth vehicle comes into being under such demand.
The conveying spiral of powder truck spreader be used for by the powder carry in feed bin to dispense position, for spreading system by its
It is dispensed on road surface.Existing powder truck spreader is usually mostly chain conveyer connection between conveying spiral and driving motor；So
And in practice, influence and chain due to factors such as machining accuracy and rigging errors after a period of use, can fluff
Etc. factors influence, center between driven sprocket and drive sprocket away from it is difficult to ensure that, lead to chain sprocket engagement not enough, transmission
Efficiency, which reduces, even to fail.
Summary of the invention
The purpose of the utility model is to provide a kind of centre of sprocket away from adjustable chain-drive mechanism, to solve existing truck spreader
The driven sprocket that chain conveyer connects between upper conveying spiral and driving motor, away from being difficult to ensure, leads to chain with drive sprocket center
Sprocket engagement is inadequate, and transmission efficiency reduces the technical issues of even failing.
The utility model is the technical scheme adopted is that a kind of centre of sprocket away from adjustable chain-drive mechanism, including is constituted
Chaindriven drive sprocket and driven sprocket；The drive sprocket is connect with driving motor output shaft；The driven sprocket with it is defeated
Expect that spiral is coaxially connected；It is characterized in that
It further include mounting plate and adjustment mechanism；
The driving motor is mounted on feed bin by mounting plate；It is bolted between the mounting plate and feed bin,
And in two mounting holes passing through of same bolt, one of them is strip-shaped hole；
The adjustment mechanism is screw thread jackscrew mechanism；
Transmission nut and feed bin in the screw thread jackscrew mechanism are connected；
The axis of drive lead screw in the screw thread jackscrew mechanism is parallel with the length direction of the strip-shaped hole, passes through transmission
Screw rod pushing installation plate, adjust drive sprocket and driven sprocket center away from.
Further, in the screw thread jackscrew mechanism axis of drive lead screw and drive sprocket and driven sprocket center company
Line is parallel.In this way, adjust between an equal amount of drive sprocket and driven sprocket center away from, need that drive lead screw advances away from
From minimum.
The beneficial effects of the utility model are:
(1) centre of sprocket of the utility model passes through the driving wire in screw thread jackscrew mechanism away from adjustable chain-drive mechanism
The mounting plate of bar pushing installation driving motor, the length for the strip-shaped hole for passing through mounting plate along the bolt of connection plate and feed bin
Direction is mobile, adjusts the installation site of driving motor, drives the position change for the drive sprocket connecting with driving motor output shaft,
And then achieve the purpose that adjust the center between drive sprocket and driven sprocket away from；Center distance regulation in place and then passes through spiral shell
Mounting plate is connect by bolt with feed bin；In this way, the center between adjustment drive sprocket and driven sprocket is away from very quick and easy, when
Center between drive sprocket and driven sprocket away from it is improper when, can be adjusted at any time；Therefore, the utility model solves existing spread
The driven sprocket that chain conveyer connects between conveying spiral and driving motor on cloth vehicle, away from being difficult to ensure, causes with drive sprocket center
Not enough, transmission efficiency reduces the technical issues of even failing for chain sprocket engagement.
(2) centre of sprocket of the utility model is away from adjustable chain-drive mechanism, preferably driving wire in screw thread jackscrew mechanism
The axis of bar is parallel with the line of drive sprocket and driven sprocket center, in this way, adjusting an equal amount of drive sprocket and driven
Center is away from the distance for needing drive lead screw to advance is minimum between sprocket wheel.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Each label is described as follows in figure:
1- drive sprocket, 2- driven sprocket, 3- adjustment mechanism, 31- transmission nut, 32- drive lead screw, 4- mounting plate, 5-
Driving motor, 6- conveying spiral, 7- feed bin.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
Referring to Fig. 1, for a kind of centre of sprocket of the utility model away from adjustable chain-drive mechanism, structure includes constituting chain conveyer
Drive sprocket 1 and driven sprocket 2, mounting plate 4 and adjustment mechanism 3.
The output axis connection of above-mentioned drive sprocket 1 and driving motor 5, in the present embodiment, driving motor 5 is mounted on installation
On plate 4, it is mounted on feed bin 7 by mounting plate 4；It is bolted between mounting plate 4 and feed bin 7, and same bolt passes through
Two mounting holes in, one of them is strip-shaped hole.Driven sprocket 2 and conveying spiral 6 are coaxially connected.
Above-mentioned adjustment mechanism 3 is screw thread jackscrew mechanism；Transmission nut 31 and feed bin 7 in screw thread jackscrew mechanism are connected；Spiral shell
The axis of drive lead screw 32 in line jackscrew mechanism is parallel with the length direction of above-mentioned strip-shaped hole, is pacified by 32 pushing tow of drive lead screw
Loading board 4, adjust drive sprocket 1 and 2 center of driven sprocket away from；In this embodiment, it is preferred that driving wire in screw thread jackscrew mechanism
The axis of bar 32 is parallel with the line at 2 center of drive sprocket 1 and driven sprocket, in this way, adjust an equal amount of drive sprocket and
Center is away from the distance for needing drive lead screw to advance is minimum between driven sprocket.
Its adjust center away from process are as follows: unclamp connection plate 4 and feed bin 7 bolt, rotary drive screw rod 32, be driven
Screw rod 32 is advanced, pushing installation plate 4, mounting plate 4 is along connection plate under the action of transmission nut 31 along own axes direction
The length direction of 4 strip-shaped holes passed through with the bolt of feed bin 7 is mobile, after being adjusted in place, then by connection plate 4 and feed bin 7
Bolt and nut is tightened, and adjustment is completed.
The centre of sprocket of the utility model can be widely applied to need to adjust drive sprocket 1 away from adjustable chain-drive mechanism
Between driven sprocket 2 center away from chain-drive mechanism in.
