Description

Technical Field

[0001] This utility model relates to the field of stacker technology, and in particular to a stacker cantilever material dropping control device. Background Technology

[0002] During the operation of a stacker, materials are piled up into a hillside structure. To ensure the stability of the pile and facilitate subsequent material handling, the two sides of the pile need to be neatly stacked to maintain an isosceles triangle shape in cross-section. However, the height of the pile changes constantly, and the stacker's discharge angle also changes. Therefore, it is crucial to ensure that the discharged material lands in the center of the pile. To achieve this, the discharge angle of the hopper needs to be adjusted according to the actual situation of the pile to control the discharge angle and thus precisely control the material falling from both sides of the pile. The traditional control method usually involves connecting a steel wire rope to the hopper and installing a handwheel at the rear. Workers turn the handwheel to wind and control the length of the steel wire rope, thereby controlling the angle of the hopper by pulling the hopper. However, this control method has some drawbacks, such as being labor-intensive, having low control precision, and being inefficient. Utility Model Content

The scraper is rotatably disposed between the fixing plates on both sides through the round holes, and a spring adjusting rod is also provided between the scraper and the fixing plates.

[0006] The beneficial effects of this utility model are: it can conveniently and quickly control the feeding angle of the hopper, reduce the labor intensity of workers, and improve control accuracy and efficiency. Attached Figure Description

Detailed Implementation

[0009] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0010] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0011] according to Figures 1-3As shown, the stacker cantilever material discharge control device includes a cantilever 1, on which a hopper 2 is mounted. The hopper 2 has an inlet end 21 and an outlet end 22, positioned between the frame sections of the cantilever 1. The cross-section of the section at the inlet end 21 of the hopper 2 is concave, with one opening side close to the feeding belt 3 to allow material to enter the hopper 2. The feeding belt 3 is also mounted on the cantilever 1, with one end aligned with the inlet end 21. Bearing seat bases 4 are mounted on both sides of the cantilever 1, and bearing seats 5 are mounted on the bearing seat bases 4. The hopper 2 is rotatably mounted on the cantilever 1 via the bearing seats 5. A hydraulic cylinder base 6 is also mounted on the cantilever 1, and a material control cylinder 7 is mounted on the hydraulic cylinder base 6. An eccentric frame 8 is mounted on one side of the hopper 2, and the movable end of the material control cylinder 7 is connected to the eccentric frame 8 to control the material discharge. The bottom of the hydraulic cylinder 7 is connected to the hydraulic cylinder base 6; a scraper 9 is also provided below the feeding belt 3; during the process of material being conveyed by the feeding belt 3, due to the high speed, the material enters the hopper 2 by rushing out of the feeding belt 3 when it reaches the end of the belt, and is then blocked by the hopper 2, and then discharged from the hopper 2 along the inner wall of the hopper. In this process, due to the high feeding speed or the viscosity of the material itself, the material on the upper layer of the feeding belt 3 is more likely to be thrown out of the feeding belt 3 than the material on the lower layer. Therefore, a small portion of the material will flow back along the lower side of the feeding belt 3 and fall to one side of the material pile under the action of gravity, thereby aggravating the uneven stacking of the material on both sides of the material pile. Therefore, it is necessary to set up a scraper 9 to block the backflowing material and allow the material to be discharged through the hopper 2, which facilitates the control of the stacking of the material pile.

[0012] The cantilever 1 has fixing plates 10 on both sides, and round holes are provided in the fixing plates 10. The scraper 9 is rotatably disposed between the fixing plates 10 through the round holes. The cantilever 1 has a fixed side plate, and the fixing plate 10 is fixedly disposed on the side plate. The two ends of the scraper 9 are disposed in the round holes of the fixing plate 10. The spring adjusting rod 11 is connected to the fixing plate 10 on both sides of the fixing plate 10. The scraper 9 is configured with an L-shaped structure, and one end is connected to the spring adjusting rod 11. The spring adjusting rod 11 presses against one end of the scraper 9 by adjusting the spring tension, so that the scraper 9 is tightly attached to the feeding belt 3.

[0013] In practical application, the material control cylinder can be used to push and pull, which can control the rotation of the hopper 2 around the bearing seat 5, thereby controlling the orientation angle of the discharge end 22 and controlling the material drop. When the feeding belt 3 is working, the tension of the spring adjusting rod 11 is adjusted to make the scraper 9 rotate, so that the scraper 9 contacts the bottom of the feeding belt 3 and scrapes off the backflowing material.

[0014] This design is ingenious. By setting up a material control cylinder, the feeding angle of the hopper can be controlled conveniently and quickly, reducing the labor intensity of workers, improving control accuracy and efficiency, and ensuring that the material falls to the center of the material pile.

[0015] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
