Description
Technical Field
[0001] This utility model belongs to the field of material handling technology, and specifically relates to a tipper receiving hopper. Background Technology
[0002] With industrial development, the demand for transporting bulk materials such as coal and ore has increased significantly. Tippers, as efficient bulk material unloading equipment, are widely used in various large-scale bulk material handling enterprises, such as ports, thermal power plants, and steel mills. As the workload of tippers continues to increase, the problem of material blockage in the receiving hoppers during frequent unloading has become increasingly prominent. Bulk materials from different sources and for different purposes have very different characteristics. In modern industry, the moisture content, viscosity, and particle size distribution of bulk materials have become more complex. Some ores may contain large amounts of moisture and sticky substances during mining, and coal may also become damp and deteriorate during storage and transportation. These complex material characteristics increase the difficulty of unloading from the receiving hopper, making material blockage more common. When handling high-moisture, high-viscosity materials, the material easily adheres to the inner wall of the receiving hopper, forming accumulations. If frequent material blockage occurs in the tipper receiving hopper during unloading, it will not only lead to material leakage and environmental pollution, but may also cause safety accidents during the clearing of blockages.
[0003] Conventional measures to prevent material blockage in receiving hoppers include installing air cannons or electric vibration devices, or both, at appropriate locations on the hopper body, in conjunction with manual hammering. However, the effectiveness varies depending on seasonality and material moisture content, affecting production efficiency and posing safety hazards. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a tipper receiving hopper to solve the problem of material blockage at the discharge port of the receiving hopper.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A tipper receiving hopper is provided, which is set above a conveyor belt and includes a hopper body. The inner wall of the hopper body is provided with an agitation device, which includes an agitation arm 1 and an agitation arm 2 arranged opposite to each other. The upper ends of the agitation arm 1 and the agitation arm 2 are movably hinged to the hopper body. The lower ends of the agitation arm 1 and the agitation arm 2 are respectively driven by a telescopic drive device set outside the hopper body to move up and down inside the hopper body. When the agitation arm 1 and the agitation arm 2 intersect, they are inserted into each other. The tail of the telescopic drive device is connected to the base bracket through a drive base.
[0007] The agitator arm one and agitator arm two are respectively connected to the two opposite inner walls of the hopper body 1.
[0008] The upper end of the stirring arm is hinged to the support by a pin. The support is fixedly connected to the inner wall of the hopper body. The lower part of the stirring arm is provided with a groove. The push rod head is connected to the groove by a pin. The push rod head passes through the hopper body and is connected to the movable rod of the telescopic drive device.
[0009] The upper end of the stirring arm 2 is hinged to the support 2 by a pin. The support 2 is fixedly connected to the inner wall of the hopper body. The lower part of the stirring arm 2 is provided with a sliding groove 2. The push rod head 2 is connected to the sliding groove 2 by a pin. The push rod head 2 passes through the hopper body and is connected to the movable rod of the telescopic drive device.
[0010] Both the first and second agitators include multiple inserts, and there are slots between the inserts that can accommodate the inserts. The number of slots in the first agitator is the same as the number of inserts in the second agitator.
[0011] The lower part of the outer wall of the hopper body is connected to a sealing cover, and the movable rod of the telescopic drive device passes through the cover to keep the telescopic drive device in a horizontal state.
[0012] The telescopic drive device is a hydraulic cylinder or a pneumatic cylinder.
[0013] Compared with existing technologies, the beneficial effects of this utility model are:
[0014] 1) The first and second stirring arms move up and down within the hopper body, which can stir the material in the receiving hopper, loosen the material, and prevent blockage.
[0015] 2) The first and second stirring arms can cross each other, and the insert teeth of the second stirring arm are inserted into the slot of the first stirring arm to shear the material, cutting large pieces of material into small pieces of fragments, further solving the problem of material blockage.
[0016] This invention employs mechanical agitation, ensuring reliable operation, preventing material blockage, and resulting in a low failure rate. It extends the service life of the receiving hopper and related equipment, reducing equipment maintenance and replacement costs. Furthermore, it improves the working efficiency of the tipper, reduces production interruptions, and increases the material throughput per unit time. Attached Figure Description
