Abstract
Description
- The present invention relates to a crushing machine pulverizing the asphalt layer (RAP), which is desired to be recycled by being removed from the place thereof, such that the RAP has dimensions which will be utilized in recycled asphalt concrete (RAC) production.
- As known, asphalt concrete obtained from the aggregate and bitumen mixture is utilized as different layers like corrosion layer, binder, straightening layer and base layers on road's upper structure. Each of these layers is produced according to recipes prepared in laboratory according to the methods of international standards in order to meet different performance requirements. Different performances expected from each layer are provided by means of recipes prepared by different maximum particle dimension, different gradation and different bitumen proportions. These performance requirements are also valid for the layers to be realized utilizing the recycled asphalt concrete (RAC).
- Asphalt concrete applied to roads should be removed after certain usage duration. Today, because of the environmental conditions, removed asphalt concrete should be recycled and utilized in the production of new asphalt concrete. Moreover, recycling of the removed asphalt concrete (hereafter it will be called RAP) and the usage thereof in the production of new asphalt concrete provides economic advantages. As the proportion of removed asphalt utilized in the production of new asphalt concrete increases, the economic advantage provided increases more.
- Thus, in the related technical field, recycling can be realized by the usage of removed asphalt concrete (RAP) in the production of new asphalt concrete (RAC). After the RAP is removed, because of the bitumen inside the RAP having aggregate granules, the RAP is in the form of small and big blocks in an adherent manner to each other. Therefore, the utilized RAP should be pulled to pieces, crushed and granulized after it is removed. After the RAP is granulized, it is added to aggregate or to other asphalt materials.
- Whatever the recycling method, the RAP shall be granulized in the best manner. In order to provide this, the RAP is poured between two rotary wheels and the RAP is broken to pieces between the teeth of the rotary wheel.

On said pulley (366), there are teeth similar to the tooth structure of the chain gears (331, 350). The support plates (363) are connected to each other by means of intermediate pieces (364) provided in between. The support plates (363) are connected by means of a bottom hinge (361) to a connection plate (327) connected to the movable bearing (322) at the bottom unit (32) from the bottom part. The bottom hinge (361) is passing through the hinge opening (28) formed on the front and rear panels (23, 24) in order to be connected to the movable bearing (322). The connection plate (327), provided for connecting the bottom hinge (361) to the movable bearing (322), is passing through at least one movement slot (273) provided on the guide wall (271). The bottom hinge (361) is connected to the connection plate (327) so as to realize a rotation movement. At the upper part, it is reclined to an upper hinge (362) fixed between the front and rear panels (23, 24). The pulleys (366) are bedded, by means of at least one bearing (368), onto the bearing shaft (367) fixed, by means of at least one assembly member (369), to the crescent flap (365) provided on the edges of the support plates (363) facing the other crushing unit (30). By means of said bedding type, the pulleys (366) are provided to realize a rotary movement on the bearing shaft (367).
- On the external wall of the crushing unit (30), there is at least one chain (50) supported by the pulleys (346) provided in the support unit (36) provided between the bottom unit (32) and the upper unit (34) and encircled by the chain gear (331) provided in the bottom unit (32) and encircled by the chain gear (350) provided in the upper unit (34). The geared palette (40) is assembled onto the chain (50) by means of connection flaps (52) embodied in L form and connected to said chain (50). Said connection flaps (52) are provided on both sides of the chain (50). As can be seen in
Figure 6 , said geared palette (40) is provided in a rectangular plate form. There is a bottom wing (43) provided as a bent part along a long edge of the geared palette (40) and there is an upper wing (44) provided as a bent part towards the other side on the opposite long edge. When the geared palettes (40) are fixed on said chain (50) in a parallel manner with respect to each other, said bottom and upper wings (43, 44) are overlapping and prevent piece passage through between. There are assembly holes (45) on the geared palette (40) for providing connection to the connection flap (52). Moreover, there is at least one crushing tooth (41) embodied in a tab form having a triangular cross section and extending from a long edge to the other edge on the opposite face connected to the connection flaps (52) of the geared palette (40). By means of the tooth gaps (47) provided between said crushing teeth (41), the crushing teeth (41) of the mutual geared palettes (40) are provided to enter into the tooth gaps (47) of each other. At least two types of teeth (41 a, 41 b) are obtained since there is at least one recess (46) on said crushing teeth (41) and since said recesses (46) are provided at different points of the crushing teeth (41). Thus, by means of the recesses (46) provided on the crushing teeth (41), the overheating and the abrasion of the crushing teeth (41) are prevented by preventing exit of the RAP thrown into the body (20) without being crushed and by preventing uninterrupted friction by the RAP at the upper parts of the crushing teeth (41). Moreover, at the upper part of the crushing teeth (41), there is at least one chamfered part (42) so as to face the tooth gaps (47). Since said chamfered part (42) faces different directions on both sides of the recess (46), the pieces are crushed more by means of this saw-like structure. The crushing tooth (41), provided in the first crushing unit (31 a), is corresponding to the tooth gap (47) provided in the second crushing unit (31 b) provided on the opposite thereof. The chain (50) comprises chain links (51) between which the teeth, provided on the chain gears (331, 350) and the pulleys (366), will enter. - There is at least one drive unit (60) connected to the drive shaft (321) for providing movement to the first crushing unit (31a). Said drive unit (60) comprises at least one engine (61) and at least one reducer (62). The reducer (62) connected to the drive shaft (321) and the reducer (62) provided in the opposite crushing unit (31 b) are bedded on at least one shaft (63) by means of at least one bearing (65) from the sides thereof facing the ground. It provides the movement together with the crushing unit (31 a, 31 b) connected to the reducer (62) by means of at least one spring (64) connected to the bearing (65) on said shaft (63). Moreover, since the two reducers (62) are bedded on the same shaft (63), the reducers (62) are prevented from rotating in an uncontrolled manner in the axis of the drive shafts (321).
- By means of the movement received by the drive unit (60), the crushing units (31 a, 31 b) realize rotary movement towards each other however at different speeds in a manner that the pieces thrown in between are guided to the outlet (22). Alternatively, the crushing units (31 a, 31 b) can be rotated in the same direction. In the preferred embodiment of the present invention, there are three chain gears (331, 350) in the bottom and upper units (32, 34). Thus, the geared palette (40) extending between the front panel (23) and the rear panel (24) is supported from the vicinity of the two edges and from the middle part thereof. The RAP, thrown into the body (20) through the inlet (21), is entering between the crushing units (31 a, 31 b). Since the RAP in the crushing units (31a, 31b) is more in amount in the inlet (21) of the distance and it is less in amount at the vicinity of the outlet (22), as the RAP thrown in pieces is lowering, the RAP is crushed between the geared palettes (40) and exits the outlet (22) in granule/particle form. Since the bottom units (32) are connected such that they are movable inside the horizontal guide (27) through the movable bearing (322), the crushing units (31 a, 31 b) are diverging from each other in case the piece, entering between the crushing units (31 a, 31 b), is very hard or very big. During this movement, the bottom units (32) are diverging from each other and the upper units (34) are performing a movement towards the inlet (21). By means of the bending arm (344), provided at the upper unit (34), and by means of the spring (348), and by means of the bending arm (324) provided at the bottom unit (32) and by means of the spring (329), when the piece, entering between the crushing units (31 a, 31 b), is removed, the crushing units (31 a, 31 b) return to the prior positions thereof. Moreover, thanks to the adjustment slots (262, 272) provided in the connection of the connection pieces (324, 349), utilized in the assembly of the springs (329, 348), to the body (20), the movement hardness of the crushing units (31 a, 31 b) and the distance in between can be adjusted by means of the tightening amount of the springs (329, 348). As the distance between the crushing units (31 a, 31 b) is changed, the piece size to be obtained is adjusted.
In an alternative embodiment of the present invention, the drive unit (60) can be connected to the upper unit (34). - The protection scope of the present invention is set forth in the annexed Claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
