[0019] The specific contents of the present invention are further described below: The pulverizer for processing biomass fuel raw materials of the present invention comprises a bottom sliding seat 1, a feeding box 2, a crushing box 3 and a conveyor 4, wherein the feeding box 2, the crushing box 3 and the conveyor 4 are arranged on the sliding seat; a pair of feeding rollers 21 are arranged in the feeding box 2, and a steel mesh 22 is arranged between adjacent feeding rollers 21 for connection, the feeding box 2 and the crushing box 3 are arranged in front and back sequence, the opening of the crushing box 3 is connected to the outlet of the feeding box 2, the lower part of the crushing box 3 is provided with a funnel outlet, the lower end of the conveyor 4 is arranged on the side of the funnel outlet, and the other end of the conveyor 4 is inclined upward, the crushing box 3 is provided with a crushing power mechanism, and the feeding box 2 is provided with a conveying power mechanism.

[0020] In this device, the feeding box 2 is connected to the feeding base through a spring 23. The feeding base is set on the bottom sliding seat 1 and arranged in pairs at the bottom of the feeding box 2. The lower part of the feeding box 2 is provided with holes for the leakage of soil and dust. A soil discharge inclined plate inclined to one side is provided on the downward side for conveying and extends to the outside of the bottom sliding seat 1.

[0021] Further explanation of the present device is that the conveying power mechanism includes a feeding motor 24, a reduction gear box and a transmission chain structure 25. The feeding motor 24 and the reduction gear box are fixed at the bottom of the feeding box 2. The conveying roller extends out of the feeding box 2 to set a driven sprocket. The output shaft of the reduction gear is provided with a driving sprocket, and a chain is provided between the driven sprocket and the driving sprocket.

[0022] In this device, the feeding box 2 is provided with a vibration mechanism, which includes a vibration motor 27, an eccentric wheel 28 and a flexible belt. The vibration motor is arranged on the feeding base, and the eccentric wheel 28 is arranged on the output shaft. The edge of the eccentric wheel 28 is connected to one end of the flexible belt, and the other end of the flexible belt is connected to the feeding box 2.

[0023] In this device, the crushing box 3 has a crushing shaft 31 and a crushing blade built therein, the crushing shaft 31 is provided with a mounting circular plate 32, the mounting circular plate 32 is provided with a pin, and the crushing blade opening is provided on the pin and can rotate.

[0024] In the device, the two groups of feeding rollers 21 rotate in opposite directions, from the incoming direction of the adjacent side to the feeding side. The feeding box 2 is closed at the top and opened at the front end, and a conveying plate is arranged in front of the opening.

[0025] The device is provided with an air selection mechanism for sweeping away debris attached to the surface of the wood feed, specifically including an air inlet cylinder, an internal air duct and a purge air outlet. The air inlet is introduced from the position of the feed box. An internal air duct is arranged inside the feed box. The end of the internal air duct is connected to a plurality of purge air outlets. The purge air outlets are directed toward the rear of the feed roller and downward, and the air inlet cylinder is connected to a high-pressure fan.

[0026] The sweeping air outlet blows the stones, stainless steel, furniture waste components, aluminum alloy, etc. carried by the wood or bamboo raw materials and other metals that cannot be removed by the iron removal device to the steel mesh at the bottom to prevent them from mixing into the crushing mechanism. This structure can increase the service life of the crusher and reduce the maintenance frequency, thereby improving production efficiency and economic benefits.

[0027] The damaged wood or bamboo raw materials are fed into the front opening of the feeding box, and the raw materials enter the pairs of feeding rollers, which press the wood or bamboo to realize feeding. At the same time, the dust on the surface falls during the pressing process. At the same time, the feeding box vibrates in the process and leaks out through the steel mesh and the hollows at the bottom of the feeding box.

[0028] After the material enters the crushing box from the feeding box, the crushing box crushes the wood and bamboo, and then leaks out from the discharge port at the bottom and enters the conveyor. This device can crush waste wood and bamboo before processing them into bio-particles to avoid the problem of shapelessness caused by coarse fibers; the wood and bamboo materials are pressed before crushing to avoid safety problems caused by splashing during crushing; the feeding pressing vibration can remove the soil on the material to avoid mixing with the bio-particle raw materials and causing a decrease in the combustion value.
