DETAILED DESCRIPTION

[0022] Please refer to Figures 1 to 8 ;

[0023] This embodiment provides a boiler coal transportation structure provided with a sampling machine, including a primary sampling machine 1, a primary belt feeder 2 is provided below the primary sampling machine 1, a crusher 3 is provided on one side of the primary belt feeder 2, a secondary belt feeder 4 is connected to the bottom output end of the crusher 3, a secondary sampling machine 5 is provided below the output end of the secondary belt feeder 4, and a sample collector 6 is installed at the bottom of the secondary sampling machine 5; Figures 1 to 8 The primary sampling machine 1 is installed on the conveyor belt of the boiler coal by connecting the trestle bottom plate a. The output end of the primary sampling machine 1 realizes material transportation through the material pipe 101 set inwardly and the primary belt feeder 2. The primary sampling machine 1 is a rotary scraper type, the sampling opening width is 204mm, the single sampling amount is 5kg, and the power is 3kw;

[0024] The primary belt feeder 2 is fully enclosed and has a motor power of 1.1kw;

[0025] Crusher speed is 960r / min, feed size is ≤45mm, discharge size is 6mm, power is 5.5kw;

[0026] The secondary belt feeder 4 is fully enclosed, and the motor power is 1.1kw;

[0027] The secondary sampler 5 is a rotary bucket type, the reduction ratio is adjusted by changing the motion cycle, and the motor power is 0.55kw;

[0028] The sample collector 6 is a sealed electric automatic can changer, the capacity of each can is 5L, the number of sample collection cans is 8, the motor power is 0.25kw, and the primary sampler 1, primary belt feeder 2, crusher 3, secondary belt feeder 4, secondary sampler 5 and sample collector 6 are all equipped with a PLC control system;

[0029] In a specific embodiment, the feed of the sampling machine is fuel coal. The primary sampling machine 1 is installed on the bottom plate a of the boiler coal transport trestle. The coal collected by the primary sampling machine 1 enters the primary belt feeder 2 through the material pipe 101. The motor in the primary belt feeder 2 is energized to drive the coal into the crusher 3 to be crushed by the roller. The crushed coal then enters the secondary belt feeder for transmission and is sampled again by the secondary sampling machine 5, and finally enters the sample collector 6 to complete the sampling, thereby realizing the effects of automatic sampling, sample preparation all-in-one machine and remote control.

[0030] Furthermore, the coal material is cuttered by the primary sampling machine 1 at a uniform speed on the belt to directly take the entire cross-section to obtain the sample coal. The sample coal enters the crusher 3 through the belt for crushing. After crushing, it becomes crushed material with a particle size less than 6 mm. The crushed material is sampled by the secondary sampling machine 5. The sampled material is finally collected in the sample collector 6. The discarded material of the secondary sampling machine 5 is returned to the original belt through the bucket elevator and the electric tee. The whole process is completely sealed without coal powder leakage. The explosion-proof motor is used to safely reduce the number of maintenance times, and the built-in PLC control system is used to realize automatic sampling and sample preparation.
