A material crushing and screening device 3 is installed between the two installation grooves 25. Installation blocks 22 are fixedly connected to the upper left and right inner walls of the feeding processing box 2. The inner wall of the feeding processing box 2 is located between the two installation blocks 22. A crushing roller 23 is rotatably connected between the two parts. The surface area of ​​the crushed biomass particles is increased, which is conducive to the pyrolysis reaction and more complete contact with oxygen, thereby improving the carbonization efficiency. A transmission mechanism is set at the rear end of the crushing roller 23. An inclined feeding plate 24 is fixedly connected to the bottom side of the right mounting block 22. A feeding hopper 26 is fixedly connected to the bottom side of the feeding box 2. An auger conveyor 27 is installed at the bottom through hole of the feeding hopper 26. The outlet of the auger conveyor 27 is connected to the inlet of the carbonization furnace 1. The inclined feeding plate 24 faces the higher end of the screen plate 33.

[0029] like Figure 3 and Figure 4As shown, the material crushing and screening device 3 includes spring telescopic rods 31, which are arranged in multiple sets within the mounting groove 25. Each spring telescopic rod 31 has a fixed plate 32 on its top side, and a screen plate 33 is fixedly connected between two fixed plates 32. A motor 34 is installed at the rear end of the feeding box 2. The output end of the motor 34 passes through the feeding box 2 and is fixedly connected to a rotating rod. The rotating rod extends below the screen plate 33 and is fixedly connected to an eccentric wheel 35. The eccentric wheel 35 impacts the screen plate 33 upon rotation. The screen plate 33 is inclined, and a baffle 36 is fixedly connected to the outside of the right fixed plate 32. The baffle 36 covers the outside of the fixed plate 32 arranged on the right end. The inclined feeding plate 24 makes the crushed material fall to the upper end of the screen plate 33, so that the crushed material has a longer screening time. The spring telescopic rod 31, motor 34 and eccentric wheel 35 can vibrate the screen plate 33 in the filtration process, speed up the screening speed of the material, and make the material that meets the specifications enter the carbonization furnace through the auger conveyor 27 for pyrolysis reaction.

[0030] like Figure 2 and Figure 3 As shown, a secondary crushing and conveying device 4 is fixedly installed at the end of the feeding box 2 away from the carbonization furnace 1 and at the outlet of the material crushing and screening device 3. A collection frame 41 is fixedly connected to the outer wall of the end of the feeding box 2 away from the carbonization furnace 1. The collection frame 41 is located next to the right mounting slot 25. A discharge channel 42 is fixedly connected to the bottom of the collection frame 41. A housing 43 is fixedly connected to the outlet of the discharge channel 42. A spiral conveying blade 44 is rotatably connected to the inside of the housing 43. A second motor 45 is installed on the top side of the spiral conveying blade 44. Both the second motor 45 and the first motor 34 are connected to an external control system.

Through screening, materials that do not meet the specifications are collected and fall into the collection frame 41 through the mounting groove 25 on the right end. Through the feeding channel 42 and the spiral conveyor blades 44, the materials are conveyed upward until they return to the feed hopper 21 through the discharge pipe 46, ready for secondary crushing. This avoids manual return or discarding of materials, reduces raw material loss, and improves carbonization efficiency and quality.

[0031] This utility model provides a low-temperature biomass pellet charcoal production device. The specific working principle is as follows: Carbonized raw materials are fed into the feed hopper 21 for crushing. A transmission structure causes the crushing roller 23 to rotate, crushing the raw materials. The crushed materials roll onto the upper end of the screen plate 33 via the inclined discharge plate 24. The screen separates materials that meet specifications from those that do not. Simultaneously, motor 34 is started, driving the eccentric wheel 35 to rotate. The rotating eccentric wheel 35 continuously impacts the screen plate 33, causing it to vibrate under the action of the spring extension rod 31. Materials that meet specifications are conveyed to the feed inlet of the carbonization furnace 1 via the auger conveyor 27, while materials that do not meet specifications fall into the collection frame 41 through the mounting groove 25 and enter the machine casing 43 through the discharge channel 42. Simultaneously, motor 45 is started, driving the spiral conveyor blades 44 to rotate. The rotating spiral conveyor blades 44 transport the incoming raw materials upwards until they fall back into the feed hopper 21 through the discharge pipe 46 for secondary crushing, ensuring uniform particle size and meeting the carbonization process requirements.
