[0021] Figure 2 yes Figure 1 Enlarged view of the middle part of the structure. DETAILED DESCRIPTION

[0022] The present invention will be further explained below in conjunction with specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] like Figure 1As shown, a wood fiber particle conveying device is characterized in that it includes a shell 1, a first conveying component 2, a second conveying component 3, a fan component 4 and a storage box 6. The shell 1 is a rectangular shell. A feed port is provided above one end of the shell 1, and a discharge port 12 is provided below the other end. A feed hopper 5 is provided on the feed port. The first conveying component 2 and the second conveying component 3 are both arranged in the shell 1. The first conveying component 2 includes a first conveying roller 21 and a first conveying belt 22. The two first conveying rollers 21 drive the first conveying belt 22 to rotate to complete the transportation. The second conveying component 3 includes a second conveying roller 31 and a second conveying belt 32. The two second conveying rollers 31 The second conveyor belt 32 is driven to rotate to complete the transportation. The second conveyor component 3 is arranged in the lower area of ​​the first conveyor component 2 and the head end of the second conveyor component 3 is located below the tail end of the first conveyor component 2. The discharge port 12 corresponds to the tail end position of the second conveyor belt 32, so that the two conveyor components form relay transportation when working. A plurality of first leakage holes are provided on the first conveyor belt 22, and the diameter of the first leakage holes is smaller than the diameter of the wood fiber particles. A second leakage hole is provided on the second conveyor belt 32, and the diameter of the second leakage hole is smaller than the diameter of the wood fiber particles. The material falling from the feed hopper 5 is transported by the first conveyor component 2 and the second conveyor component 3 and then falls from the discharge port 12.

[0024] like Figure 1 As shown, the fan assembly 4 is arranged on the shell 1, and the fan assembly 4 includes a first air duct 41, a second air duct 42 and a fan 43. The fan 43 is arranged on the outer top wall of the shell 1. The first air duct 41 and the second air duct 42 are both connected to the fan 43. When the fan 43 is working, negative pressure is generated at the air suction ports of the first air duct 41 and the second air duct 42, so as to draw the gas of the shell 1 outward. The air suction port position of the first air duct 41 corresponds to the first conveyor belt 22, and the air suction port position of the second air duct 42 corresponds to the second conveyor belt 32. When the airflow passes through the materials on the two conveyor belts, it can dissipate heat and cool the materials. After passing through the two conveyor belts, the temperature of the materials decreases and falls from the discharge port 12.

[0025] like Figure 1 and Figure 2 As shown, a first filter screen 51 is provided in the feed hopper 5, and the mesh diameter of the first filter screen 51 is larger than that of the wood fiber particles. The extruded wood fiber particles enter from the top of the feed hopper 5. The first filter screen 51 can reduce the wood fiber particles from agglomerating into the shell 1, which is convenient for the first conveying component 2 below to convey. The feed hopper 5 is connected to the fan 43 through a connecting pipe 44. The inlet of the connecting pipe 44 is located on the side wall behind the first filter screen 51 on the feed hopper 5. A second filter screen 52 is provided at the inlet of the connecting pipe 44. The filter hole diameter of the second filter screen 52 is much smaller than that of the wood fiber particles. The inlet of the connecting pipe 44 generates negative pressure in the feed hopper 5, thereby reducing the flying dust generated when the wood fiber particles enter the feed hopper 5.

[0026] like Figure 1As shown, the tail end of the first conveying assembly 2 is located in the second air duct 42, and a notch corresponding to the first conveyor belt 22 is provided on the side of the second air duct 42. The tail end of the first conveyor belt 22 enters the second air duct 42 from the notch. The wood fiber particles transported on the first conveyor belt 22 pass through the second air duct 42 and fall onto the second conveyor belt 32. The negative pressure in the second air duct 42 can absorb the dust mixed with the wood fiber particles when they fall. The second air duct 42 is provided with a screen 421, which is located below the first conveyor belt 22 and its height is lower than the first conveyor belt 22. The first conveyor belt 2 2, the wood fiber particles on the second conveyor belt 32 fall onto the second conveyor belt 32 after passing through the screen 421. The mesh holes of the screen 421 are larger than the particle size of the wood fiber particles. The screen 421 can reduce the wood fiber particles from falling in a cluster, which is conducive to the wood fiber particles being evenly spread on the second conveyor belt 32. The second air duct 42 is also provided with a third filter 422, which is located above the screen 421 and has a height higher than the first conveyor belt 22. The filter hole diameter of the third filter 422 is smaller than the particle size of the wood fiber particles, so as to prevent the wood fiber particles from being accidentally sucked away.

[0027] like Figure 1 As shown, a collecting hopper 13 is provided at the bottom of the shell 1, and the collecting hopper 13 is in an inverted cone shape. The collecting hopper 13 is located below the first conveying component 2 and the second conveying component 3. The collecting hopper 13 is connected to the storage box 6. The storage box 6 includes a first storage bin 61 and a second storage bin 62. The collecting hopper 13 is connected to the first storage bin 61. When the first conveying component 2 and the second conveying component 3 convey wood fiber particles, some accidentally dropped particles enter the first storage bin 61 from the collecting hopper 13. The fan 43 is connected to the second storage bin 62. A filter bag 63 is provided in the second storage bin 62. The air drawn from the shell 1 by the fan 43 is filtered by the filter bag 63 and then discharged, and the dust remains in the second storage bin 62 for easy collection.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
