In addition, in this disclosure, the terms "first," "second," etc. are used to distinguish one element from another without sequence or importance. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated.
It should be noted that, the bucket-wheel stacker-reclaimer is a high-efficiency loading and unloading machine for continuous conveying of large-scale dry bulk cargo storage yards (for example, in the present disclosure, for coal yards), which is composed of a cantilever belt capable of pitching and horizontally swinging, bucket wheels at the front end of the cantilever belt, a frame body and other mechanisms, the cantilever belt can run bidirectionally, the bucket wheels take materials and send out the materials through the cantilever belt during material taking, and the goods conveyed by the main conveyor are thrown to the storage yards through the cantilever belt during material piling, because the structure and principle of the bucket-wheel stacker-reclaimer are well known to those skilled in the art, and excessive description is not made here.
In the present disclosure, in order to avoid the complexity of description, a simple description is used for all the mentioned "belt structures", such as the cantilever belt 20, the climbing belt 30, the first conveyor belt 50, etc., which will be mentioned below, all refer to a complete belt transmission mechanism including a pulley frame for transmission and a conveyor belt body mounted on the pulley frame.
Referring to fig. 1, the present disclosure provides a blending system of coal, including a bucket-wheel stacker-reclaimer, the bucket-wheel stacker-reclaimer comprising: the frame body 10, one end is fixed on the frame body 10, and the cantilever belt 20, the climbing belt 30 and the wheel bucket 40 that the other end is unsettled to stretch out horizontally. The climbing belt 30 is obliquely arranged, the lower end is used for connecting a first coal source, and the upper end is fixed on the frame body 10 and is positioned above the cantilever belt 20 so as to convey the coal of the first coal source onto the cantilever belt 20 through the climbing belt 30 (the conveying direction of the coal is the direction shown by an arrow B in the figure); a bucket 40 is mounted at the free end of the cantilever belt 20 for scooping coal from the second coal source onto the cantilever belt 20. Wherein the bucket 40, the ramp belt 30, and the cantilever belt 20 are operated in synchronization, the cantilever belt 20 is configured to discharge coal from the first and second coal sources thereabove from an end of the cantilever belt 20 remote from the bucket 40 (a direction of conveyance of the coal on the cantilever belt 20 is shown by arrow C in the figure).
In the embodiment of the disclosure, the running speeds of the bucket 40, the climbing belt 30 and the cantilever belt 20 can be adaptively adjusted according to the proportion requirement of the blended coal, and in addition, the accuracy of the proportion of the blended coal can be ensured by adjusting the angle position of the bucket wheel 40 and the speed of supplying the climbing belt 30 with the coal at the first coal source.
When the mixing system is started, the wheel bucket 40 and the climbing belt 30 are required to be started in an idle mode, but the starting sequence of the wheel bucket 40 and the climbing belt 30 is not required to be limited, and only the wheel bucket 40, the climbing belt 30 and the cantilever belt 20 are required to be ensured to keep synchronous operation when the wheel bucket 40, the climbing belt 30 and the cantilever belt 20 start to convey coal for mixing, wherein the synchronous operation does not mean that the speeds of the wheel bucket 40, the climbing belt 30 and the cantilever belt are the same, but the wheel bucket, the climbing belt and the cantilever belt can be in an operation state at the same time.
In addition, in order to avoid coal flowing out to both sides in the cantilever belt 20 or the climbing belt 30, the belts (e.g., the cantilever belt 20, the climbing belt 30, etc.) in the present disclosure are each configured in a U-shaped structure with a cross section that is concave in the middle and has both sides higher. In addition, in other embodiments, risers may be added to both sides of the belt perpendicular to the direction of movement, as this disclosure is not limited.
To increase the efficiency of the drive of coal (e.g., to avoid slippage) on a belt (e.g., cantilever belt 20, climbing belt 30, etc.), in some embodiments, the surface of the belt may be provided with raised bars at equidistant intervals to increase the belt drive force on the coal.
Through the technical scheme, the climbing belt 30 and the wheel bucket 40 can respectively convey two different coals to the cantilever belt 20 for mixing, and the cantilever belt 20 can move to discharge the coals which are mixed on the cantilever belt from one end far away from the wheel bucket 40 for standby, so that the coal mixing which can be completed by the cooperation of two bucket-wheel stacker-reclaimers can be completed by only one bucket-wheel stacker-reclaimer.

In order to enable the coal scooped up by the bucket 40 to slide onto the cantilever belt 20, referring to fig. 2, in some embodiments, the cantilever belt 20 may be further provided with a coal chute plate 100 engaged with the bucket 40, one end of the coal chute plate 100 being fixed to the cantilever belt 20, and the other end being inclined to extend upwardly below the downward opening of the bucket 40, so that the coal in the bucket 40 slides onto the cantilever belt 20 through the coal chute plate 100, wherein the bucket 40 is installed at a position near the suspended end and on one of both sides of the extension direction of the cantilever belt 20.
The bucket 40 may include a plurality of claws disposed about a circular path and each of the claws may be rotated in a circular path when the bucket 40 is in operation to scoop coal into the claw when the claw is in a lower position and the coal therein may fall under the claw due to gravity onto the chute plate 100 when the claw is rotated to a higher position and then slide down onto the cantilever belt 20 through the chute plate 100, the construction and principle of the cantilever belt 20, the bucket 40 and the chute plate 100 on the bucket-wheel stacker are well known to those skilled in the art and will not be described further herein. Of course, the different bucket wheel stacker-reclaimers may be somewhat different in construction, nor is the disclosure limited thereto so long as the bucket wheel 40 is capable of scooping coal onto the boom belt 20.
Further, in order to prevent coal sliding down from the chute plate 100 from sliding off the other side of the cantilever belt 20 opposite the bucket 40 due to inertia, referring to fig. 2, in some embodiments, the other side of the cantilever belt 20 opposite the bucket 40 near the suspended end may be fitted with a second liftable baffle 92 for withstanding coal sliding off the chute plate 100. Similar to the first shutter 91 described above, in this embodiment, the second shutter 92 may be mounted on the pulley frame of the cantilever belt 20, and the second shutter 92 is in a raised state (not affecting the normal transfer of coal by the cantilever belt 20) when the bucket-and-wheel stacker is stacking at ordinary times, and the second shutter 92 is lowered to a position on the side of the cantilever belt 20 for resisting coal (when the lower end of the second shutter 92 may be in moving contact with the cantilever belt 20) when the material is taken or mixed (i.e., when the bucket 40 supplies coal to the cantilever belt 20), preventing coal from slipping out from the side of the cantilever belt 20 opposite to the bucket 40.
