Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 6 As shown, a remote control system for quantitative loading of coke includes a coke storage bin 1, a dust hood 2, a camera 3, a radar level meter 4, a DCS control system 5, a display 6, and an electric bell 7. The dust hood 2 is fixedly provided on the outer side of the discharge pipe of the coke storage bin 1, and a pipe on the dust hood 2 is directly connected to a negative pressure pipe for dust removal and adsorption.

[0029] A gate valve 8, a lifting mechanism 9 and a lifting chute 10 are provided in the dust removal cover 2. The gate valve 8 is provided on the discharge pipe of the coke storage bin 1. The fixed end of the lifting mechanism 9 is fixed to the top of the dust removal cover 2. The movable end of the lifting mechanism 9 is fixed to the fixed end of the lifting chute 10. The lifting chute 10 is placed below the discharge pipe of the coke storage bin 1.

[0030] According to the height of the cargo box of different trucks, the distance from the lifting chute 10 to the cargo box is adjusted by the lifting mechanism 9, the gate valve 8 is opened, and the discharge pipe of the coke storage bin 1 discharges the coke.

[0031] The lifting mechanism 9 is an electric hoist or a hydraulic cylinder. The fixed end of the lifting mechanism 9 is the casing of the electric hoist or the cylinder body of the hydraulic cylinder. The movable end of the lifting mechanism 9 is the hook of the electric hoist or the telescopic end of the hydraulic cylinder. The lifting mechanism 9 is an electric hoist, and the height of the lifting chute 10 is adjusted by lifting and lowering the electric hoist. The lifting mechanism 9 is a hydraulic cylinder, and the height of the lifting chute 10 is adjusted by lifting and lowering the telescopic end of the hydraulic cylinder. A dust cover can be put on the outside of the electric hoist or the hydraulic cylinder.

[0032] The lifting chute 10 includes a bracket 11, a drop hopper 12, and a telescopic cylinder 13. The bracket 11 is composed of two parallel support rods 11.1 and an n-shaped rod 11.2 fixed between the ends of the two support rods 11.1. The fixed end of the lifting chute 10 is the n-shaped rod 11.2; the drop hopper 12 is rotatably connected to the bottom of the support rod 11.1 through a rotating shaft 14. The telescopic cylinder 13 can be a hydraulic cylinder and also has a dust cover. The cylinder body of the telescopic cylinder 13 is rotatably connected to the support rod 11.1, and the telescopic end of the telescopic cylinder 13 is rotatably connected to the side plate 15 fixed to the rotating shaft 14. Material troughs 16 are symmetrically fixed on both sides of the top of the drop hopper 12.

[0033] The telescopic end of the telescopic cylinder 13 is extended and retracted, pushing and pulling the side plate 15, causing the rotation shaft 14 to rotate, thereby driving the bottom of the drop hopper 12 to tilt left and right, which can change the coke discharge direction and make the coke laid relatively evenly in the cargo hopper. The material trough 16 prevents material from leaking from the side when the drop hopper 12 is tilted.

[0034] A camera 3 and a radar level meter 4 are also fixed in the dust cover 2. The camera 3 is connected to the display 6 by signal. The signal output end of the radar level meter 4 is connected to the signal input end of the DCS control system 5. The DCS control system 5 is electrically connected to the bell 7, the gate valve 8, the lifting mechanism 9 and the driving end of the lifting chute 10 respectively. The driving end of the lifting chute 10 is a telescopic cylinder 13.

[0035] The image of the cargo box of the truck is transmitted to the display 6 through the camera 3 for presentation. It is manually judged that the cargo box of the truck is parked in place and is under the dust hood 2. The dust hood 2 and the truck are not completely closed, so the camera 3 is not affected by dark light. The dust hood 2 absorbs dust under negative pressure, reduces flying dust, and also reduces the influence of the camera 3. The radar level meter 4 collects the information that the cargo box is loaded in place, gives it to the DCS control system 5 and controls the gate valve 8 to close, and the lifting mechanism 9 lifts the lifting chute 10.

[0036] The speaker 17 is also included. The speaker 17 is connected to the microphone by a wire. The speaker 17 is arranged near the coke storage bin 1 .

[0037] Working principle: When the utility model is in use, the truck moves to the bottom of the coke storage bin 1, and the truck cargo box image is transmitted to the display 6 through the camera 3 for presentation. When the truck cargo box is stopped, the microphone can be used to give voice to the on-site speaker 17 to prompt the driver to adjust the position;

[0038] The lifting mechanism 9 and the gate valve 8 are started in sequence, and the lifting mechanism 9 adjusts the bottom of the drop hopper 12 of the lifting chute 10 to the cargo bucket, and the gate valve 8 is opened, and the discharge pipe of the coke storage bin 1 discharges the coke for loading. During this period, the side plate 15 can be pushed and pulled by the telescopic cylinder 13, so that the rotating shaft 14 rotates and drives the bottom of the drop hopper 12 to tilt left and right, so that the coke is laid relatively evenly in the cargo bucket;

[0039] The radar level meter 4 senses that the loading of the cargo bucket is in place and gives information to the DCS control system 5. The DCS control system 5 first controls the gate valve 8 to close, then controls the telescopic cylinder 13 of the lifting chute 10 to reset, and finally lifts the lifting chute 10 through the lifting mechanism 9;

[0040] The electric bell 7 sounds to remind the driver that the special car has been completed and the driver can leave, or the speaker 17 can also give a voice prompt.

[0041] The technology of this application has the following effects:

[0042] 1. Remotely monitor the arrival of trucks and control feeding and loading, reducing the number of on-site operators and preventing harmful gases and dust from harming the human body.

[0043] 2. The material level meter senses the loading amount, realizing remote and accurate quantitative coke loading without manual visual judgment, preventing coke dust from affecting the line of sight, avoiding repeated loading and unloading of coke by vehicles, and improving work efficiency.

[0044] 3. No personnel are required on site, loading is automatic, and one person can control the loading of multiple vehicles at the same time. It has a high degree of automation, is fast and convenient, shortens loading time, reduces labor intensity, and reduces labor costs.
