All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1 , Figure 3 and Figure 4 As shown, the present invention proposes a coal crushing and conveying device, which includes an equipment frame 1, a crushing and conveying structure 2 and a dust removal structure 3. The crushing and conveying structure 2 is mounted on the equipment frame 1. The equipment frame 1 is arranged in a gate shape and has three sets of horizontal plates in the upper, middle and lower parts. The dust removal structure 3 is mounted on the equipment frame 1. The crushing and conveying structure 2 includes a crushing unit 4 and a conveying unit 5. The crushing unit 4 is located in the middle of the equipment frame 1, and the conveying unit 5 is located in the lower part of the equipment frame 1 and below the crushing unit 4.
[0021] The crushing unit 4 includes a jaw crusher 6, a feeding hopper 7, a toothed roll crusher 8, and a hammer crusher 9. The jaw crusher 6 is fixedly mounted on the top plate above the equipment frame 1. The moving jaw and stationary jaw of the jaw crusher 6 are made of special alloy material, which has high wear resistance and high strength and can withstand large crushing forces. The feeding hopper 7 is fixedly mounted above the jaw crusher 6. The toothed roll crusher 8 is fixedly mounted on the middle horizontal plate of the equipment frame 1, and its feed inlet is located below the discharge port of the jaw crusher 6. The toothed roll surface of the toothed roll of the toothed roll crusher 8 is provided with specially shaped crushing teeth, and the crushing teeth are combined with different tooth shapes to make the coal particle size more uniform. The hammer crusher 9 is fixedly mounted on the lower horizontal plate of the equipment frame 1, and its feed inlet is located below the discharge port of the toothed roll crusher 8. The hammer head of the hammer crusher 9 is made of a new composite material, which is lightweight but has strong impact toughness and can crush coal to the required particle size under high-speed rotation.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the crushing unit 4 includes a closed shell 10 and a conveyor 11. The closed shell 10 is fixedly installed below the equipment frame 1 and the feed inlet is located below the discharge port of the hammer crusher 9. The conveyor 11 is installed inside the closed shell 10. The closed shell 10 is only provided with a feed inlet at the front end and a discharge port at the rear end. The conveyor 11 is seamlessly fitted inside the closed shell 10.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the dust removal structure 3 includes a dust collection hood 12, a dust suction pipe 13, and a dust collector 14.

[0024] In practical use, the jaw crusher 6, toothed roll crusher 8, hammer crusher 9, conveyor 11, and dust suction pipe 13 are started simultaneously. First, the mined coal is placed into the feeding hopper 7, where it falls into the feed inlet of the jaw crusher 6. The jaw crusher 6 then performs initial coarse crushing, breaking larger coal pieces into suitable medium sizes. The crushed coal pieces fall from the discharge outlet of the jaw crusher 6 into the feed inlet of the toothed roll crusher 8. The toothed roll crusher 8 then further crushes the coal from the first stage, and the crushed coal pieces fall from the discharge outlet of the toothed roll crusher 8 into the hammer crusher. At the feed inlet of the hammer crusher 9, the coal is finely crushed by the impact of the hammer head and the rebound action of the impact plate, improving crushing efficiency and quality. The crushed coal blocks fall into the feed inlet of the closed shell 10 and onto the conveyor belt of the conveyor 11 for transport to the destination position, and then are discharged from the discharge outlet at the rear end of the closed shell 10. At the same time, during crushing, the dust collector 14 sucks up the dust generated by the jaw crusher 6, toothed roll crusher 8 and hammer crusher 9 through the dust collection pipe 13 and the dust collection hood 12 to avoid harming the environment. The above is the entire operation process of the coal crushing and conveying device.
