Description

Technical Field

[0001] The utility model relates to the field of bulk material transportation and stacking, and in particular to stacking and reclaiming equipment for large bulk material storage yards. Background Art

[0002] In order to realize the inherent retrieving and stacking functions of the stockyard and satisfy the direct-through function of the ground belt conveyor on the existing stacker-reclaimer, two methods are usually adopted: one method is to adopt a movable double-tail car structure. When the direct-through function needs to be satisfied, the movable tail car is operated to descend to realize the direct passage of the ground belt conveyor; the other method is to switch the unloading chute so that the material enters the cantilever belt conveyor or falls directly on the ground belt conveyor.

[0003] There are generally two ways to switch the unloading chute: one is to set up a unloading chute in the central cylinder of the stacker-reclaimer, and through the gate switch valve, the bulk materials sent by the tail car are either transported forward through the cantilever belt conveyor and then unloaded to the yard, or pushed to the unloading chute and then fall back to the ground belt conveyor; the other is to install two sets of chutes leading to the cantilever belt conveyor or the ground belt conveyor respectively at the front and back, and by shortening or removing the distance from the tail car, the materials fall into chutes at different positions.

[0004] The above methods all have common disadvantages, that is, complex structure, higher cost and cumbersome operation. Utility Model Content

[0005] According to the problems existing in the prior art, the utility model provides a stacker, aiming to solve the problems of the existing stacker with a straight-through function having a complex structure and a complex operation mode.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a stacker, including a gantry and a traveling mechanism, a main structure, a tail car and a ground belt conveyor; the ground belt conveyor passes around the tail car; the main structure is installed on the gantry and the traveling mechanism; the main structure is provided with a front cantilever frame, and the front cantilever frame is equipped with a cantilever belt conveyor; the head of the tail car is equipped with a discharge hopper located above the cantilever belt conveyor, the cantilever belt conveyor adopts a forward and reversible belt conveyor, the tail of the cantilever belt conveyor extends beyond the rear of the discharge hopper, and the tail of the cantilever belt conveyor is equipped with a collecting hopper located above the straight-through part of the ground belt conveyor.

[0007] Preferably, the tail car is connected to the main structure or the gantry and the traveling mechanism; the gantry and the traveling mechanism support the weight of the entire machine and can drive the tail car to move along the ground track.

[0008] Preferably, the main structure includes a slewing mechanism and a pitching device.

[0009] Preferably, a counterweight is installed at the rear of the main structure to balance the front cantilever frame, the cantilever belt conveyor and the front offset load.

[0010] The utility model has the following beneficial effects: simple structure, convenient operation and broad application prospects. The installation position of the front cantilever frame and the cantilever belt conveyor is moved backward, and a collecting hopper, i.e. a material discharge chute structure, is adopted at the tail of the cantilever belt conveyor; when the cantilever belt conveyor runs forward, the material is transported to the yard; and when it runs backward, the material passes through the chute and then falls back to the ground belt conveyor, realizing the straight-through function; and when there are two conveyor belts on the ground, the function of conveying across the belt conveyors can also be realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 This is a schematic diagram of cross-belt conveyor transportation. DETAILED DESCRIPTION

[0013] like Figure 1 , 2 As shown, a stacker comprises a gantry and a traveling mechanism 1, a main structure 2, a tail car 3 and a ground belt conveyor 6; the ground belt conveyor passes around the tail car 3; the main structure 2 is installed on the gantry and the traveling mechanism 1; the main structure 2 is provided with a front cantilever frame 4, and the front cantilever frame 4 is installed with a cantilever belt conveyor 5; the head of the tail car 3 is installed with a discharge hopper 8 located above the cantilever belt conveyor 5, the cantilever belt conveyor 5 adopts a reversible belt conveyor, the tail of the cantilever belt conveyor 5 extends beyond the rear of the discharge hopper, and the tail of the cantilever belt conveyor 5 is installed with a collecting hopper 9 located above the straight-through part of the ground belt conveyor 6; the tail car 3 is connected to the main structure 2; the rear of the main structure 2 is installed with a counterweight 7 for balancing the front cantilever frame 4 and the cantilever belt conveyor 5 and the front overload.

[0014] The main structure 2 of the utility model includes a slewing mechanism and a pitching device, and the cantilever belt conveyor 5 installed on the front cantilever frame 4 can unload the materials transported by the ground belt conveyor 6 to any position in the yard through the joint operation of slewing, pitching and walking. The rear counterweight 7 is used to balance the front eccentric load of the front cantilever frame 4 and the cantilever belt conveyor 5.

[0015] The ground belt conveyor 6 runs upward along the tail car 7, and then goes back to the ground belt bracket from the bottom of the gantry; the bulk materials are transported upward along the tail car 7 to the top discharge hopper 8 along the ground belt conveyor 6, which is consistent with the existing structure; then they slide down to the cantilever belt conveyor 5 below. The tail of the cantilever belt conveyor 5 exceeds the rear of the discharge hopper, which is convenient for the installation of the collection hopper 9 located above the straight-through part of the ground belt conveyor 6 at the tail of the frame; the discharge hopper 8 and the collection hopper 9 are generally used for material collection and diversion like the existing collection chute.

[0016] At this time, there are two working conditions to choose from. One is that the cantilever belt conveyor 5 turns forward and the materials are sent to the front end of the front cantilever frame 4 for unloading. Through the single or combined operation of the whole machine's rotation, pitching and walking, the materials can be stored at any designated position in the yard. The other is that after the cantilever belt conveyor 5 turns in the opposite direction, the cantilever belt conveyor 5 and the materials from the tail car are transported backward and fall into the collecting hopper 9, and then slide down to the ground belt conveyor 6 below, completing the straight-through working condition.

[0017] When there are other belt conveyors on the ground, the collecting hopper 9 can be aimed at other belt conveyors on the ground through the rotation operation, so that the cross-belt conveyor transportation is realized. Compared with the existing stacking machine, the function is enriched.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
