Wherein in the working process of the spiral distributor of carrying the material, because bituminous mixture stirs inadequately, the installation of preventing the segregation board at present does not possess adjustable function, and the large granule can form at the both ends of road and pile up under the effect that receives great centrifugal force simultaneously, all can cause the segregation phenomenon. Such road surface construction is not conform to the quality requirement, very big influence operation flow and efficiency, so the utility model provides a paver spiral material distributor that can prevent educing solves the above-mentioned problem of proposing.
SUMMERY OF THE UTILITY MODEL
The utility model provides a paver spiral material distributor, can effectual solution large granule raw materials to the accumulational problem in road both sides, make simultaneously prevent that the segregation baffle has possessed adjustable advantage, can improve the segregation phenomenon in the spiral material distributor transportation process at to a great extent.
In order to solve the problem explained above, the spiral distributing device adopts a structure of a double-spiral rotating shaft, and comprises a spiral distributing device body and is characterized in that: including two spiral rotating shafts that are distribution from top to bottom, top spiral rotating shaft is first spiral rotating shaft, and below spiral rotating shaft is second spiral rotating shaft, and half forward direction rotating vane is installed on first spiral rotating shaft right side, and half reverse direction rotating vane is installed on the left side, and the epaxial rotating vane installation of first spiral rotating shaft and second spiral rotating is revolved to opposite. The connecting shafts are installed on two sides of the two spiral rotating shafts through bolt connection, the gear and the plate frame are installed on the connecting shafts respectively, and the asphalt mixture is stirred more uniformly through relative rotation of the two spiral rotating shafts.
Two symmetrical first gears are arranged at the left end and the right end of the first spiral rotating shaft, two symmetrical second gears are arranged at the left end and the right end of the second spiral rotating shaft, the first spiral rotating shaft is driven by the plunger variable pump to work, the torque of the second spiral rotating shaft is transmitted by the first spiral rotating shaft through the external engagement of the two gears, the transmission ratio of the first gears to the second gears is 1:1, the rotating directions of the first spiral rotating shaft and the second spiral rotating shaft are opposite, the central distance of the two gears is approximately equal to 1/2 of the distance between the highest position of the blade on the first spiral rotating shaft and the lowest position of the blade on the second spiral rotating shaft, the asphalt mixture is stirred more uniformly under the action of the two spiral rotating shafts, meanwhile, in the process of conveying the mixed materials by the first spiral rotating shaft, the large particle grids free from two sides can be blocked back to the middle position by the reverse rotation of the second spiral rotating shaft. The problem of large granule raw materials gathering in road both sides is effectual improved.
Connecting shafts are arranged on the left side and the right side of the two spiral rotating shafts and used for installing gears and fixedly installing plate frames. The plate frame is installed on the outer side of the gear on the connecting shaft, and the installation mode of the plate frame and the connecting shaft is as follows: the connecting shaft left end and the right-hand member are all fixedly mounted with bearings, the outer portion of each bearing is fixedly provided with a mounting block, the top of the mounting block on the left side is fixedly connected with the left end of the bottom of the upper plate frame, the top of the mounting block on the right side is fixedly connected with the right end of the bottom of the upper plate frame, and the mounting mode of the lower plate frame is the same as that of the upper plate frame. Therefore, under the condition that the rotation directions of the upper spiral shaft and the lower spiral shaft are opposite, the angle between the two plate frames can be adjusted, so that the adjustable function of the separation-preventing baffle plate is realized.

The invention is further described with reference to the following figures and examples.
Fig. 1 is a schematic structural view of an auger.
Fig. 2 is a schematic structural diagram of the first spiral rotating shaft.
Fig. 3 is a schematic structural view of a mounting mode of the plate frame.
In the figure: 1 a first spiral rotating shaft, 2 a positive rotating blade, 3 a connecting shaft, 4 a first gear,
5 second gear, 6 plate frames, 7 anti-segregation baffle plates, 8 reverse rotating blades, 9 second spiral rotating shafts, 10 connecting shafts, 11 plate frames, 12 mounting blocks and 13 bearings
Detailed Description
The first spiral rotating shaft 1 is driven by a plunger variable pump to drive an inclined shaft motor to rotate through the transmission of a chain. The positive rotating blades 2 are arranged on the right half part of the first spiral rotating shaft 1, the reverse rotating blades 8 are arranged on the left half part of the first spiral rotating shaft 1 and are responsible for uniformly stirring and paving the asphalt mixture on the whole pavement, the connecting shafts 3 are respectively arranged on the left side and the right side of the first spiral rotating shaft 1, the first gear 4 is arranged on the connecting shafts 3 and is externally meshed with the second gear 5 to transmit the torque to the second spiral rotating shaft 9, the rotation directions of the second spiral rotating shaft 9 and the first spiral rotating shaft 1 are opposite, and the transmission ratio of the first gear 4 to the second gear 5 is 1: 1. The reverse rotating blade 8 is installed on the right half part of the second spiral rotating shaft 9, the forward rotating blade 2 is installed on the left half part of the second spiral rotating shaft, 1/2 of the distance between the highest position of the blade on the first spiral rotating shaft and the lowest position of the blade on the second spiral rotating shaft is approximately equal to the size of the center distance between the two gears is selected, and therefore the asphalt mixture can be stirred more uniformly under the action of the two spiral rotating shafts. Because centrifugal force's influence in the transportation process of mixture can make the large granule gather to road both sides, because turning to of second spiral pivot 9 is opposite with first spiral pivot 1, and the rotating vane of installation revolves to opposite in two pivots, so the rotating vane on the second spiral pivot 9 can block great granule to a certain extent and free to the distributing device both ends, has improved the mixture at the accumulational phenomenon in road both sides to a great extent.
The position that the gear again leans on outside on connecting axle 3 is fixed to be installed with sheet frame 6, takes the mounting means of sheet frame as an example: and bearings 13 are respectively arranged on the left end connecting shaft and the right end connecting shaft, and mounting blocks 12 are fixedly arranged outside the bearings 13. The top of the left mounting block is fixedly connected with the left end of the bottom of the upper plate frame, the top of the right mounting block is fixedly connected with the right end of the bottom of the upper plate frame, and the mounting mode of the lower plate frame is the same as that of the upper plate frame. Because the first spiral rotating shaft 1 and the second spiral rotating shaft 9 are opposite in direction, the plate frame can adjust the angle between the upper plate frame and the lower plate frame in the feeding process of the distributor, and the adjustable function of the anti-segregation baffle is realized. Therefore, the distributor can better play a role in preventing segregation under different working conditions and conveyed mixed materials.
Finally, it is noted that the above examples are only for illustrating the technical solutions of the present invention and not for limiting, and although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principle and spirit of the present invention, and all shall be covered by the scope of the claims of the present invention.
