Description

Technical Field

[0001] This utility model relates to the field of building materials machinery technology, and in particular to an intelligent walking environmentally friendly unloading machine. Background Technology

[0002] Currently, the equipment used for unloading bulk materials such as coal, ore, and limestone at docks and other locations is mostly bridge-type grab unloaders, which operate in an open manner and easily generate a large amount of fugitive dust during material transfer. Existing water spray dust suppression technology is difficult to adapt to special materials such as limestone and gypsum that are prone to caking when exposed to water, and the equipment relies on trailers or rail traction for movement, requires external power supply, and has a low level of intelligence. Although similar unloading equipment abroad can achieve basic unloading functions, they are mostly customized products, with high procurement costs and long delivery cycles.

[0003] Furthermore, existing unloading machines generally lack windproof and securing structures, making them prone to tipping over during typhoons or sudden gusts of wind due to their large overall structure. Therefore, there is an urgent need for a specialized unloading device that combines green dust removal, autonomous movement, independent power supply, intelligent control, safety protection, and ease of maintenance to address the shortcomings of existing technologies.

[0026] The following combination Figures 1-4 The present invention will be described in further detail below.

[0027] This utility model discloses an intelligent walking environmentally friendly unloading machine. The intelligent walking environmentally friendly unloading machine includes a frame 1, a dry dust collection device 2, a remote-controlled walking and turning drive system 3, a generator power supply system 4, an automatic lifting hydraulic control system 5, an electrical control system 6, and a windproof fixing system 7.

[0028] The dry dust collection device 2 is installed on the top of the frame 1. The dry dust collection device 2 includes a hopper 21, a discharge grid 22, and an insertion pulse flat bag dust collector. The hopper 21 includes an upper chamber 211 and a lower chamber 212. The discharge grid 22 is installed in the upper chamber 211. The insertion pulse flat bag dust collector is placed obliquely in the lower chamber 212. The outer surface of the filter bag captures dust. The dust collector is equipped with a back-blowing nozzle, which is connected to a compressed air source. The pulse cycle can be adaptively adjusted in real time according to the dust concentration in the hopper 21. During the back-blowing operation, the dust falls into the hopper 21 and mixes with the material before being discharged.

[0029] The material discharge grid 22 includes an elastic sealing baffle 221, which is a rubber plate. A guide plate 222 is bolted to the top of the elastic sealing baffle 221. The guide plate 222 is inclined and welded to the inner wall of the upper hopper 211 on both sides. The guide plate 222 guides the material to fall and has a dust sealing effect. When the material falls, it pushes the elastic sealing baffle 221 to lift up. An upper support rod 223 is horizontally fixed to the top of the guide plate 222 and horizontally fixed to the bottom of the guide plate 222. The lower support rod 224 is fixedly installed inside the material discharge grid 22 with multiple rows of longitudinal support plates. The ends of the upper support rod 223 and the lower support rod 224 are welded to the longitudinal support plates. The upper support rod 223 and the lower support rod 224 are both made of round steel, which provides stable support for the guide plate 222 and ensures the structural stability of the guide plate 222 under working conditions such as material impact. At the same time, after the material is discharged, the lower support rod 224, together with the elastic sealing baffle 221, achieves reset and closure by its own tension, ensuring the dustproof sealing effect.

[0030] The remote-controlled walking and turning drive system 3 is installed at the bottom of the frame 1. The remote-controlled walking and turning drive system 3 includes a wireless remote control handle, a walking wheel set, and a drive motor. The wireless remote control handle integrates control buttons for forward, backward, left and right turns, lifting, and emergency stop. The drive motor and the walking wheel set are connected by a steering drive reducer. After receiving the remote control signal, the drive motor outputs power to drive the walking wheel set to achieve stepless speed regulation. The walking wheel set uses wear-resistant rubber wheels, which are suitable for concrete operation scenarios such as docks.

[0031] The generator power supply system 4 is located inside the frame 1. The generator power supply system 4 includes a diesel generator fixedly installed on the frame 1. The diesel generator is electrically connected to the drive motor, hydraulic pump, insertion pulse flat bag dust collector, PLC controller and other components through wires. It is also equipped with an overload protection module. The diesel generator outputs a stable voltage to meet the rated power requirements of each electrical component.

[0032] The automatic lifting hydraulic control system 5 is installed at the bottom of the frame 1. The automatic lifting hydraulic control system 5 includes four sets of liftable hydraulic cylinders, a hydraulic pump, a hydraulic valve group, and an oil tank. The four sets of liftable hydraulic cylinders are fixedly installed at the four corners of the bottom of the frame 1. The piston rod of the hydraulic cylinder is connected to a support foot. The hydraulic pump controls the extension and retraction of the hydraulic cylinder through the hydraulic valve group, which is adapted to the height requirements of receiving equipment such as dock conveyor belts and material tank trucks. The system is equipped with a pressure relay and a hydraulic gauge to monitor the hydraulic system pressure and hydraulic oil level in real time. In case of abnormality, the electrical control system 6 is triggered to alarm.

[0033] The electrical control system 6 is located inside the frame 1 and includes a PLC controller, a touch screen, and a wireless remote control receiver. The PLC controller is electrically connected to the diesel generator start / stop switch, the hydraulic valve group solenoid coil, the dust collector backflushing module, and the drive motor speed control module, respectively, to monitor the drive motor status, the hydraulic cylinder extension / retraction height, and the dust collection system resistance value in real time. It is equipped with an emergency stop button and an audible and visual alarm system. In case of a fault, the touch screen displays the fault type (such as motor overload, abnormal hydraulic system pressure, etc.), and the audible and visual alarm system is activated at the same time. The wireless remote control receiver communicates wirelessly with the wireless remote control handle (including the emergency stop button) to meet the remote operation needs of large-span operation areas such as docks.

[0034] The windproof fixing system 7 includes lifting lugs, high-strength windproof cables, and ground anchor connectors installed at the four corners of the frame 1. When the equipment is not in operation or encounters strong winds, the high-strength windproof cables fix the equipment to the ground anchor connectors pre-set at the dock to prevent the equipment from shifting or overturning.

[0035] The implementation principle of the intelligent walking environmentally friendly unloading machine of this utility model embodiment is as follows: The operator starts the diesel generator and moves the equipment to the designated working position below the ship unloader through the wireless remote control handle. It is fixed to the ground anchor connected to the dock through the high-strength windproof cable. The extension length of the hydraulic cylinder is set to the required working height through the touch screen. The PLC controller controls the hydraulic pump to start working. After the hydraulic cylinder extends to the target height, the pressure relay provides real-time feedback signal and the hydraulic pump automatically stops running.

[0036] The unloader's grab bucket feeds bulk materials into hopper 21. The elastic sealing baffle 221 of the material drop grid 22 opens due to the impact of the material, and the material falls to the bottom of hopper 21. At the same time, the insertion-type pulse flat bag dust collector starts, and dust is captured on the outer surface of the filter bag. The fan discharges clean air to the atmosphere. According to the preset pulse cycle of 1.5 minutes, the PLC controller controls the back-blowing nozzle to spray compressed air, and the dust on the surface of the filter bag falls into hopper 21. Together with the material, it is transported to the dock conveying equipment through the discharge port. After the operation is completed, the equipment is moved to the designated storage area by the wireless remote control handle, the hydraulic cylinder is controlled to retract to the lowest stroke position, the diesel generator is turned off, and it is fixed again by the high-strength windproof cable and the ground anchor connection.

[0037] The intelligent walking environmentally friendly unloading machine of this utility model adopts a dry dust collection device 2, which eliminates the need for water spraying, avoids material caking or blockage of conveying pipelines when exposed to water, and achieves a dust collection efficiency of over 95%, meeting the emission limits required by docks and other facilities. It eliminates the reliance on trailers or rail traction, and features multi-wheel drive and wireless remote control for 360° turning, adapting to irregular operating areas at docks. The equipment utilization rate is significantly improved compared to traditional fixed unloading machines. The diesel generator enables operation without external power supply, making it suitable for scenarios such as newly built ports and open-pit mines without power supply infrastructure. The unloading capacity meets the daily transfer needs of tens of thousands of tons at medium and large-sized docks.

[0038] The dual control mode of "wireless remote control handle + touch screen" allows operators to start working without professional training. The audible and visual fault alarms and precise touch screen display reduce the difficulty of operation and troubleshooting. The emergency stop and high-strength windproof fixing system effectively prevent equipment tipping and misoperation risks. Each system has clearly marked lubrication points (such as reducer lubrication ports and bearing grease nipples) and maintenance cycle markings. Hydraulic / electrical faults can be quickly located via the touch screen, and the annual maintenance cost is significantly lower than that of similar foreign equipment. The production and procurement of equipment parts are controllable, and the manufacturing cost per unit is significantly lower than that of similar customized foreign products. The short delivery time makes it highly competitive in the market.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
