Technical Field

[0001] This utility model belongs to the field of automobile unloading technology, specifically relating to an enclosed automatic unloading system for automobiles. Background Technology

[0002] With the continuous development of automation control technology, the degree of automation in unloading is getting higher and higher. However, with the popularization of intelligent and unmanned processes, as well as enterprises' demand for green and environmentally friendly practices, higher requirements have been put forward for the efficiency and environmental protection of unloading materials such as ores, ferroalloys, and alloys.

[0003] Currently, to replenish underground silos, dump trucks are used to transport materials to the replenishment port, where the truck bed is tilted and the materials are poured into the unloading port. The materials are then transported to the corresponding silos by a belt conveyor. However, materials such as ores, ferroalloys, and lime generate a large amount of dust during the tilting and unloading process, which has an adverse impact on the work site and the surrounding environment.

[0015] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings. Example 1

[0016] Reference Figures 1-2 An enclosed automatic unloading system for automobiles includes a dust hood 2, a dust removal duct 1 at the top of the dust hood 2 connected to an existing dust collector, an air outlet control valve 7 inside the dust removal duct 1, a roller shutter door 3 on one side of the dust hood 2, compressed air nozzles 4 inside the left and right sides of the dust hood 2 adjacent to the roller shutter door 3, an infrared sensor 5 below the compressed air nozzles 4, and a first limit 6, a second limit 8, a third limit 9 and an unloading port 10 of an underground silo sequentially arranged at the bottom of the dust hood 2 away from the roller shutter door 3, and a belt conveyor below the unloading port 10.

[0017] The roller shutter door 3 is equipped with an upper limit stop device at its top.

[0018] The dust hood 2 has an external control box 11 on its side. The control box 11 contains switches for controlling the air vent control valve 7, the roller shutter door 3, the automatic unloading device, the belt conveyor start / stop, and the compressed air nozzle 4. The control box is electrically connected to the infrared sensor 5. The automatic unloading device uses a manual pneumatic control valve to open and close the lifting hydraulic distribution valve, adjusting the flow and direction of the hydraulic oil. When the truck bed needs to be raised, the driver initiates the lifting operation via a button in the cab, allowing the cargo to be unloaded. When the truck bed tilts to its limit, the limit valve automatically cuts off the oil circuit, keeping the truck bed in the tilted position. The automatic unloading device has three switches for lifting, lowering, and slow lowering. Three Bluetooth remote-controlled finger robots (Xiaomi) are installed at the corresponding positions of these three buttons. Bluetooth is installed in the control box 11. By connecting the finger robots to the control box 11 via Bluetooth, the automatic unloading device can be remotely controlled via Bluetooth.

[0019] The compressed air nozzle 4 is connected to the air compressor via a pipe and is used for cleaning after unloading.

[0020] When using, such as Figure 3 As shown, when the car arrives, the infrared sensor 5 determines that the car has arrived and transmits a signal to the control box 11 to control the opening of the roller shutter door 3. The car reverses into the dust hood 2, and the first limit switch 6, the second limit switch 8, and the third limit switch 9 open and determine whether the car is in position. After the car stops, the driver goes outside the dust hood 2 to operate the control box 11, activate the automatic unloading device, and simultaneously open the air vent control valve 7 and the belt conveyor. The roller shutter door 3 is closed, and the automatic unloading device automatically flips the truck bed. After unloading is completed, the compressed air nozzle 4 is opened after the roller shutter door 3 is opened to blow the car. Because the air vent control valve 7 of the dust hood 2 is not closed at this time, the unloading position is in a slightly negative pressure state, and the blowing angle is also inward. Therefore, a small amount of dust will be sucked into the dust removal system and will not overflow. 30 seconds after the blowing ends, the driver enters and drives away. With the first limit switch 6, the second limit switch 8, and the third limit switch 9 all closed, press the automatic unloading end button in the control box 11, close the air outlet control valve 7 and the belt conveyor, and close the roller shutter door 3 after a 60-second delay. The entire process is now complete.

[0021] The embodiments described herein are 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 included within the scope of protection of this utility model.
