Description

Technical Field

[0001] The utility model relates to the technical field of slag scrapers, in particular to a conveyor belt jacking type material receiving port of a slag scraper. Background Art

[0002] A scraper, also known as an excavator loader, is a vital piece of machinery widely used in mining, tunnel excavation, and civil engineering. Its primary function is to efficiently and continuously remove and transport ore, providing strong support for modern construction. The basic structure of a traditional scraper consists of key components such as the scraper claw, conveyor belt, hydraulic system, and frame. The scraper claw is responsible for grabbing and removing the ore, and through a series of complex movements, it transports the ore into the collection hopper in front of the conveyor belt.

[0003] In actual operation, each time a scraper removes material, the scraper claw pushes the previously removed material onto the conveyor belt. However, during this process, material that falls circumferentially during the pushing process accumulates in the hopper. While most material successfully falls onto the conveyor belt for transport, a small amount, located far from the conveyor belt, cannot reach the conveyor belt and remains in the hopper. Even if pushed by the scraper claw, material can still accumulate on either side. Therefore, after the scraper claw has repeatedly removed material from the hopper, the operator must perform a separate material transfer operation to transfer the material circumferentially within the hopper to the conveyor belt. Otherwise, material will accumulate around the hopper, requiring subsequent secondary collection.

[0004] Furthermore, because the claws are hydraulically controlled, operators are prone to improper operation when shifting materials, causing the claws to excessively contact the hopper wall, resulting in displacement or scratches in the hopper, affecting subsequent use. This problem has not been effectively addressed in existing scrapers, seriously affecting their operating efficiency and service life. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. As long as the effect of the utility model can be played, various changes can be made to the implementation scheme.

[0026] Through the personnel in the art, the parts in the case are connected in sequence, and the specific connection and operation sequence should refer to the following working principle, and the detailed connection means is the technology known to the art, and the following mainly introduces the working principle and process.

[0027] Refer to Figure 1-5 A conveyor belt lifting material receiving port of a slag scraper according to this embodiment is described.

[0028] like Figure 1 As shown, the scraper includes a frame 1 and a conveyor belt 2 arranged in the frame 1, and a collecting hopper is provided at the feeding end of the frame 1.

[0029] In this embodiment, if Figure 2 and Figure 3 As shown, an inner base 4 is provided at the bottom of the collecting hopper 3, and a bottom plate member is provided on the inner base 4, and the bottom plate member includes a front bottom plate member 7 and a rear bottom plate member 5. One end of the front bottom plate member 7 and the rear bottom plate member 5 are rotatably connected by a connecting shaft 8, and the other end of the rear bottom plate member 5 is rotatably connected to the inner base 4 through a rotating shaft 12. A thrust assembly is provided at the bottom of the bottom plate member, which pushes the rear bottom plate member 5 to flip toward the conveyor belt 2 with the rotating shaft 12 as the axis, so that the front bottom plate member 7 and the rear bottom plate member 5 at the bottom of the collecting hopper 3 that receive the mineral material are bent at the connecting shaft 8, so that the rear bottom plate member 5 is tilted toward the conveyor belt 2 with the rotating shaft 12 as the axis, so that the mineral material accumulated on the surface of the rear bottom plate member 5 falls into the conveyor belt 2.

[0030] Further, such as Figure 2 and Figure 3 As shown, in order to ensure the consistency of the bending position of the front bottom plate 7 and the rear bottom plate 5 each time, a wall slide groove 6 is opened on the inner wall of the collecting hopper 3, and the outer side of the connecting shaft 8 extends outward and extends into the wall slide groove 6. When the front bottom plate 7 and the rear bottom plate 5 are bent by the connecting shaft 8, the connecting shaft 8 moves in the wall slide groove 6 to limit the bending of the front bottom plate 7 and the rear bottom plate 5.

[0031] In this embodiment, the inner base 4 is used to support the front bottom plate 7 and the rear bottom plate 5. Figure 5 As shown, it specifically includes a base 44, which is fixed to the bottom of the aggregate hopper 3. A gusset plate 41 and a cavity portion 42 are respectively provided at both ends of the inner side of the base 44, wherein the front bottom plate 7 is located above the gusset plate 41, the rear bottom plate 5 is located at the cavity portion 42, and the thrust assembly is located in the cavity portion 42. When the front bottom plate 7 and the rear bottom plate 5 are bent, the gusset plate 41 is exposed to receive the mineral material dropped by the front bottom plate 7, and when the front bottom plate 7 returns to a horizontal state, a part of the mineral material is shoveled to its surface, and a part of the mineral material is pushed down. The pushed down mineral material will enter the aggregate hopper 3 with the next scraping operation of the slag bucket. The cavity portion 42 is used to accommodate the thrust assembly.

[0032] Furthermore, side strips 43 are fixed on both sides of the cavity portion 42 , and the rear bottom panel 5 is overlapped on the side strips 43 to provide support for the rear bottom panel 5 when it is restored to a horizontal position.

[0033] In addition, if Figure 3As shown, a transverse groove 13 is opened on the inner wall surface of the base 44 located at the buckle plate 41, and sliders are provided at both ends of the front bottom plate 7 close to the feeding end of the collecting hopper 3. When the front bottom plate 7 is bent and tilted and restored to the horizontal, the sliders on both sides are slidably connected in the transverse groove 13 to assist the sliding movement of the front bottom plate 7.

[0034] like Figure 2 and Figure 3 As shown, the above-mentioned thrust assembly includes a telescopic rod 10 and a hydraulic cylinder 9, the hydraulic cylinder 9 is tiltedly arranged in the cavity portion 42, and the telescopic rod 10 is tiltedly arranged in the cavity portion 42, wherein the tilt directions of the hydraulic cylinder 9 and the telescopic rod 10 are oppositely arranged.

[0035] The telescopic rod 10 is a hollow cylinder with a rod body that can be extended and retracted within the hollow cylinder. The bottom of the hollow cylinder is the fixed end, and the rod body is the output end. The fixed end of the telescopic rod 10 is hinged to the base 44, and the output end of the telescopic rod 10 is hinged to the rear bottom plate 5, near the connecting shaft 8. The output end of the hydraulic cylinder 9 is hinged to the output end of the telescopic rod 10.

[0036] During the advancing work, the hydraulic cylinder 9 advances and pushes the output end of the telescopic rod 10 outward, and the front bottom plate 7 and the rear bottom plate 5 are bent during the advancing work; the hydraulic cylinder 9 retracts and pulls the output end of the telescopic rod 10 back into the fixed end, and the front bottom plate 7 and the rear bottom plate 5 are restored to the level during the pulling back work.

[0037] In one embodiment, Figure 4 As shown, the rear bottom panel 5 has several strip-shaped slots 14, within which strip plates 11 are movably mounted, with the tops of the strip plates 11 extending beyond the top surfaces of the strip slots 14. Side plates 16 are provided at the bottom edges of the strip plates 11, the tops of the side plates 16 being connected to the bottom surface of the rear bottom panel 5 via springs 17, which are tension springs. Several protrusions 15 are provided on the top surface of the strip plates 11.

[0038] When the rear bottom plate 5 is in an inclined state and the mineral material on the surface falls along its inclined surface, the change in the weight of the mineral material on the surface of the rear bottom plate 5 during the falling process and the contact with the protrusion 15 on the top surface of the strip plate 11 cause the strip plate 11 to vibrate through the spring 17, preventing the mineral material from sticking to the rear bottom plate 5 and facilitating the separation of the mineral material from the rear bottom plate 5.

[0039] 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
