Specific implementation method:

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] like Figure 1-Figure 5 As shown, an automatic sampling device for the tail of a coke belt is used in production, comprising a pair of tracks 1 and a moving vehicle 2, a sample receiving bucket device 3, and a sample collecting bucket device 4;

[0024] The sample receiving bucket device 3 is fixed at the front end of the mobile vehicle 2, and the mobile vehicle 2 is slidably placed between a pair of rails 1, and a column 20 is fixed at the bottom of the pair of rails 1, and the pair of rails 1 are two symmetrically arranged channel steels;

[0025] The belt conveyor operates normally, the material-dropping end of the belt conveyor is above a pair of rails 1, coke drops from between the pair of rails 1, the mobile vehicle 2 moves on the rails 1, and drives the sample receiving bucket device 3 to move to the material-dropping end of the belt conveyor to receive the sample.

[0026] The sample receiving hopper device 3 includes a hopper 5 and a concave arc-shaped bottom plate 6 that pass through the upper and lower parts. The concave arc-shaped bottom plate 6 is placed under the hopper 5 and covers the bottom of the hopper 5. Side plates 7 are fixed on both sides of the concave arc-shaped bottom plate 6. The middle part of the side plate 7 is rotatably connected to the side of the hopper 5 through a rotating shaft 8. The concave arc-shaped bottom plate 6 is rotatably connected to the hopper 5 through the middle part of the side plate 7, so that the concave arc-shaped bottom plate 6 is in a balanced posture directly below the hopper 5. When the sample receiving hopper device 3 receives the sample, the sample passes through the hopper 5 and falls to the middle part of the concave arc-shaped bottom plate 6. The concave arc-shaped bottom plate 6 is impacted by the falling sample and will shake slightly, but will not flip over, and will not cause an excessively large opening between the concave arc-shaped bottom plate 6 and the bottom of the hopper 5 to prevent the sample from falling out. The side bottom of the hopper 5 is also adapted to the concave arc-shaped bottom plate 6 to be made into an arc structure, and a shift rod 9 is fixed to the side of any side plate 7.

[0027] The mobile vehicle 2 includes a U-shaped headstock 10, a moving plate 11, rollers 12, an electric hydraulic push rod 13, and a support plate 14. The U-shaped headstock 10, the moving plate 11, and the electric hydraulic push rod 13 are arranged in sequence from front to back. The concave surface of the U-shaped headstock 10 is the front end of the mobile vehicle 2. The hopper 5 of the sampling hopper device 3 is fixed to the concave surface of the U-shaped headstock 10. Two moving plates 11 are fixed to the outer side surface of the U-shaped headstock 10. Two rollers 12 are respectively rotatably connected to the side surfaces of the two moving plates 11. The rollers 12 roll within the channel steel of the track 1. The telescopic end of the electric hydraulic push rod 13 is fixed to the outer side surface of the U-shaped headstock 10, and the fixed end of the electric hydraulic push rod 13 is fixed to the support plate 14. The end of the support plate 14 is fixed to the bottom of the track 1. The rod body of the electric hydraulic push rod 13, that is, the fixed end, is fixed to the track 1 through the support plate 14. The telescopic movement of the telescopic end of the electric hydraulic push rod 13 drives the U-shaped headstock 10 to move reciprocally. When the U-shaped headstock 10 moves, it rolls and contacts the track 1 through the rollers 12 on the moving plate 11.

[0028] A push plate 15 is fixed to one side of the column 20. The stop rod 9 is movably abutted against the push plate 15. When the sampling hopper device 3 withdraws and pours the sample after receiving the sample, it can drive the stop rod 9 on the side plate 7 of the lower concave arc-shaped bottom plate 6 to abut against the push plate 15 and be blocked by the push plate 15. As a result, the hopper 5 is still moving, while the lower concave arc-shaped bottom plate 6 is limited and receives an opposite force, so that it flips along the rotating shaft 8, and the opening between the lower concave arc-shaped bottom plate 6 and the bottom of the hopper 5 expands, so that the sample can be automatically dropped out.

[0029] The sample receiving hopper device 4 is placed below between a pair of tracks 1 and is adjacent to the push plate 15. The sample receiving hopper device 4 includes a receiving chute 16 and a receiving pipe 17. The opening at the top of the receiving pipe 17 is in a flared shape. The receiving chute 16 is inclined and its bottom is fixed at the opening of the receiving pipe 17. The sample dropped out from the expanded opening between the lower concave arc-shaped bottom plate 6 and the bottom of the hopper 5 slides down the receiving chute 16 into the receiving pipe 17 to complete the sample collection.

[0030] It further includes two proximity switches 18. The two proximity switches 18 are respectively arranged at the bottom of the track 1. The proximity switches 18 are connected in series with the circuit of the electric hydraulic push rod 13. The distance between the two proximity switches 18 is the stroke of the telescopic end of the electric hydraulic push rod 13. A dial 19 is fixed to the moving plate 11. The dial 19 movably contacts any one of the proximity switches 18. When the electric hydraulic push rod 13 drives the mobile vehicle 2 to move for receiving or pouring the sample, the moving distance from receiving the sample to pouring the sample is realized by the dial 19 movably contacting the two proximity switches 18. When the proximity switch 18 is triggered, the electric hydraulic push rod 13 is powered off, and thus the mobile vehicle 2 can stop at the sample receiving position or the sample pouring position.

[0031] Working principle: One end of a pair of tracks 1 is placed below the dropping end of the belt conveyor. When the belt conveyor operates normally, coke drops from between the pair of tracks 1.

[0032] When taking samples, Figure 1 As shown, the telescopic end of the electric hydraulic push rod 13 extends to drive the mobile vehicle 2 to move toward the belt conveyor, and the U-shaped headstock 10 places the hopper 5 of the sample receiving hopper device 3 below the dropping end of the belt conveyor. The paddle 19 contacts the corresponding contact switch 18, the electric hydraulic push rod 13 is powered off and stops, and the sample passes through the hopper 5 and falls to the middle of the concave arc bottom plate 6.

[0033] When pouring the sample, Figure 5 As shown, the telescopic end of the electric hydraulic push rod 13 retracts and drives the mobile vehicle 2 to move away from the belt conveyor. The shift rod 9 of the concave arc-shaped bottom plate 6 of the sample receiving hopper device 3 presses against the push plate 15 and is blocked by the push plate 15, so that the hopper 5 is still moving, while the concave arc-shaped bottom plate 6 is limited and subjected to opposite forces, thereby flipping along the rotating shaft 8, and the opening between the concave arc-shaped bottom plate 6 and the bottom of the hopper 5 is expanded. The paddle 19 contacts the corresponding contact switch 18, and the electric hydraulic push rod 13 is powered off and stops. At this time, it slides from the concave arc-shaped bottom plate 6, automatically falls out through the expanded opening, and then slides down the receiving trough 16 to the receiving tube 17 to complete the sample collection.

[0034] In the process of conveying and dropping materials by the belt conveyor, the present application uses the mobile vehicle 2 to drive the sample receiving bucket device 3 to move to complete the whole process of receiving and pouring samples, replacing manual sampling. A fixed amount of samples can be taken within a certain period of time. The sampling is highly representative and can also avoid the safety risks of personnel sampling being contaminated by dust and being hit by falling coke.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
