Description

Technical Field

[0001] The present invention relates to a method for positioning the track of a combined mobile belt conveyor. More specifically, it relates to a method for accurately and reliably positioning the main mobile belt conveyor for the fermentation bin and the telescopic mobile belt conveyor for entering and exiting the bin in a dynamic tunnel composting process, using a unique track surface structure in conjunction with a universal current monitoring instrument, without manual on-site intervention. Background Art

[0002] As a subsystem of a mechanized composting system, the material distribution system is crucial for achieving unmanned, intelligent composting operations. Currently, material distribution equipment typically utilizes belt spreaders, spiral spreaders, or a combination, depending on the core process. For dynamic tunnel composting, due to its unique characteristics, a combined mobile belt spreader is typically installed in the distribution corridor at the head of the composting area to achieve this goal.

[0003] The combined belt conveyor consists of four belt conveyors and connecting parts, including a main fixed belt conveyor, a main mobile belt conveyor and two telescopic mobile belt conveyors. The operation positioning of the mobile belt conveyor is generally achieved by contact or non-contact travel switches, but in practice there are the following problems:

[0004] (1) Since the material distribution equipment is located at the opening of the closed tunnel, the overflow of high temperature, high humidity, toxic and harmful gases during the material distribution process can easily cause damage to the travel switch, and the system reliability is not high;

[0005] (2) There is a signal lag in the travel switch, especially for the main mobile belt conveyor. Due to its large mass and inertia, it often fails to enter the position accurately.

[0006] In actual engineering projects, when a travel switch is used to position a combined mobile belt feeder track, a manual observation post must be set up at the head of the warehouse, and unmanned operation cannot be truly achieved. Summary of the Invention

[0007] In view of this, the main purpose of the present invention is to provide a combined mobile belt feeder track positioning method, which, through a unique walking track surface structure and in conjunction with a universal current monitoring instrument, can accurately and reliably realize the positioning of the main mobile belt conveyor fermentation bin and the positioning of the telescopic mobile belt conveyor in and out of the bin without manual work on site.

[0008] To achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: a combined mobile belt feeder track positioning method is provided, comprising: a main rail positioning groove, a telescopic rail front positioning groove, and a telescopic rail rear positioning groove, the main mobile belt conveyor carries two telescopic mobile belt conveyors and moves along the main track in a specified direction, at this time, the rear traveling wheel of the telescopic mobile belt conveyor is located in the rear positioning groove of the telescopic rail, when the front traveling wheel of the main mobile belt conveyor enters the main positioning groove corresponding to the target fermentation bin, the current of the main mobile belt conveyor travel motor is significantly reduced compared to when traveling horizontally, at this time, the main mobile belt conveyor travel system stops working, the corresponding telescopic mobile belt conveyor starts the travel system, the telescopic mobile belt conveyor travels along the telescopic track toward the fermentation bin, at this time, the current of the telescopic mobile belt conveyor travel system increases rapidly, when the rear traveling wheel of the telescopic mobile belt conveyor drives out of the rear positioning groove of the telescopic rail, the current of the travel motor returns to a stable state of horizontal travel, when the front traveling wheel of the telescopic mobile belt conveyor drives into the front positioning groove of the telescopic rail After that, the current of the telescopic mobile belt conveyor's travel motor is significantly lower than that of the horizontal travel. At this time, the telescopic mobile belt conveyor's travel system stops working and starts the material distribution process. After the material distribution is completed, the telescopic mobile belt conveyor's travel system is started to move back. At this time, the current of the telescopic mobile belt conveyor's travel system increases rapidly. When the front travel wheel of the telescopic mobile belt conveyor drives out of the front positioning groove of the telescopic rail, the travel motor current returns to a stable state of horizontal travel. When the rear travel wheel of the telescopic mobile belt conveyor enters the rear positioning groove of the telescopic rail, the current of the telescopic mobile belt conveyor's travel motor is significantly lower than that of the horizontal travel. At this time, the telescopic mobile belt conveyor's travel system stops working and the main mobile belt conveyor starts the travel system. At this time, the current of the main mobile belt conveyor's travel system increases rapidly. When the front travel wheel of the main mobile belt conveyor drives out of the main rail positioning groove, the travel motor current returns to a stable state of horizontal travel. At this point, a material distribution process is completed and the combined mobile belt distribution machine drives to the next fermentation bin. The above process achieves the following purposes: (1) The distribution machine realizes true unmanned automatic control. (2) Mechanical positioning increases system reliability while also enabling correlation of current signals. (3) Current signals can be transmitted and collected via the travel motor cable, significantly increasing reliability.

At this time, the rear traveling wheel of the telescopic moving belt conveyor 7 is located in the rear positioning groove 3 of the telescopic rail. When the front traveling wheel of the main moving belt conveyor 6 enters the main positioning groove 1 corresponding to the target fermentation bin, the current of the traveling motor of the main moving belt conveyor 6 is significantly reduced compared to when walking horizontally. At this time, the traveling system of the main moving belt conveyor 6 stops working, and the corresponding telescopic moving belt conveyor 7 starts the traveling system. The telescopic moving belt conveyor 7 travels along the telescopic track 5 toward the fermentation bin. At this time, the current of the traveling system of the telescopic moving belt conveyor 7 increases rapidly. When the rear traveling wheel of the telescopic moving belt conveyor 7 drives out of the rear positioning groove 3 of the telescopic rail, the current of the traveling motor returns to a stable state of horizontal walking. When the front traveling wheel of the telescopic moving belt conveyor 7 drives into the front positioning groove 2 of the telescopic rail, the current of the traveling motor of the telescopic moving belt conveyor 7 is significantly reduced compared to when walking horizontally. Phenomenon, at this time, the telescopic mobile belt conveyor 7 walking system stops working and starts the material distribution process. After the material distribution is completed, the telescopic mobile belt conveyor 7 walking system is started to retreat. At this time, the current of the telescopic mobile belt conveyor 7 walking system increases rapidly. When the front walking wheel of the telescopic mobile belt conveyor 7 drives out of the front positioning groove 2 of the telescopic rail, the walking motor current returns to a stable state of horizontal walking. When the rear walking wheel of the telescopic mobile belt conveyor 7 enters the rear positioning groove 3 of the telescopic rail, the walking motor current of the telescopic mobile belt conveyor 7 is significantly reduced compared to the horizontal walking. At this time, the telescopic mobile belt conveyor 7 walking system stops working and the main mobile belt conveyor 6 starts the walking system. At this time, the current of the main mobile belt conveyor 6 walking system increases rapidly. When the front walking wheel of the main mobile belt conveyor 6 drives out of the main rail positioning groove 1, the walking motor current returns to a stable state of horizontal walking. At this point, a material distribution process is completed and the combined mobile belt distribution machine drives to the next fermentation bin. The above process achieves the following purposes: (1) The distribution machine realizes true unmanned automatic control. (2) While increasing the system reliability through mechanical positioning, the correlation of current signals is realized. (3) The current signal can be transmitted and collected through the traveling motor cable, which greatly increases the reliability.
