[0027] Please also refer to Figures 1 to 4 , a wood chip pre-wetting device according to a preferred embodiment of the present utility model, includes a conveying mechanism and a stirring mechanism. The conveying mechanism and the stirring mechanism are fixedly arranged in the vertical direction through a bracket 1, and the conveying mechanism is arranged above the stirring mechanism. In this embodiment, universal wheels 101 are arranged at the bottom of the bracket 1 to facilitate moving the device to the required position.
[0028] The conveying mechanism includes a conveying shell 21 and conveying rods 22. The conveying shell 21 is fixedly connected to the bracket 1. One side of the conveying shell 21 away from the stirring mechanism is provided with a shell opening, and one end of the conveying shell 21 facing the stirring mechanism is provided with a discharge port; the conveying rods 22 are spiral conveying rods, and there are two conveying rods 22. The conveying rods 22 are rotatably arranged in the conveying shell 21, and the conveying rods 22 are driven by a first power mechanism so that the two conveying rods 22 rotate in opposite directions and the material is conveyed to the discharge port.
[0029] The stirring mechanism includes a stirring shell 31 and stirring rods 32. One end of the stirring shell 31 is connected to the discharge port through a connecting pipe 4, and the other end is provided with a discharge port 311; there are two stirring rods 32. The stirring rods 32 are rotatably arranged in the stirring shell 31. Both ends of the stirring rods 32 are spiral blades 321, and the middle part of the stirring rods 32 is a paddle stirring piece 322. The paddle stirring pieces 322 of the two stirring rods 32 are engaged with each other. The two stirring rods 32 are driven by a second power mechanism so that the two stirring rods 32 rotate in opposite directions and the material is conveyed to the discharge port 311.
[0030] The connecting pipe 4 is provided with a water adding pipe 41, and the water adding pipe 41 is communicated with the connecting pipe 4.
[0031] Add wood chips at the shell opening. Under the action of the two conveying rods 22, the wood chips can be evenly discharged through the discharge port and enter the connecting pipe 4. At the same time, the water adding pipe 41 injects water into the connecting pipe 4, realizing the uniform presetting of the wood chips in the connecting pipe 4. When the wood chips enter the stirring mechanism, under the action of the spiral blade 321 at the front end of the stirring rod 32, the wood chips move along the direction close to the discharge port 311. When the wood chips move to the middle of the stirring shell 31, the paddle stirring piece 322 stirs the wood chips, making the wood chips fully combine with the water and ensuring that the wood chips can be completely pre-wetted. When the wood chips move to the rear end of the stirring shell 31, under the thrust of the spiral blade 321, the pre-wetted wood chips are discharged from the discharge port 311.
[0032] The overall structure of this embodiment adopts a high-length and low-width structure.

[0033] As Figure 1 、 Figure 2 As shown in the figure, a feeding frame 5 is arranged at the shell opening. Both ends of the feeding frame 5 are open structures. One end of the feeding frame 5 is fixedly connected to the conveying shell 21 and communicates with the shell opening. A screen 51 is arranged at the other end of the feeding frame 5, and the screen 51 is inclined. When the diameter of the sundries is larger than the aperture of the screen 51, the sundries will slide out of the feeding frame 5 along the screen 51, thereby screening the wood chips and preventing large sundries from damaging the equipment.
[0034] As Figure 3 As shown in the figure, a sweeping brush 6 is arranged at one end of the feeding frame 5 close to the screen 51. A brush head 601 is arranged on the side of the sweeping brush 6 facing the screen 51, and the brush head 601 abuts against the screen 51. Both ends of the sweeping brush 6 are slidably connected to the inner wall of the feeding frame 5 through slide rails 61 respectively. A ball screw 62 is fixedly penetrated through the middle of the sweeping brush 6, and both ends of the ball screw 62 are rotatably connected to the inner wall of the feeding frame 5 respectively. The ball screw 62 is driven by a cleaning motor 63 so that the sweeping brush 6 can reciprocate in the feeding frame 5. The cleaning motor 63 drives the ball screw 62 to rotate, so that the sweeping brush 6 can reciprocate along the inclined direction of the screen 51, and at the same time, the brush head 601 cleans the mesh holes of the screen 51.

[0036] Although the screen 51 can limit large impurities from falling into the feed frame 5, wood chips can also clog the screen 51. When the screen 51 is clogged, the speed at which wood chips enter the feed frame 5 will be reduced, or even wood chips cannot enter the feed frame 5. In this embodiment, the cleaning motor 63 drives the ball screw 62 to rotate, so that the sweeping brush 6 can reciprocate along the tilt direction of the screen 51, and the brush head 601 cleans the mesh of the screen 51. The cleaning motor 63 of this embodiment is tilted and has the same tilt as the screen 51. The cleaning motor 63 is fixed to the outer wall of the feed frame 5 through a fixing plate.

[0039] The first power mechanism drive and the second power mechanism drive respectively include a driving motor 71 and a reducer 72. The driving motor 71 is connected to the reducer 72 through a transmission belt 711. The reducer 72 is connected to the corresponding any conveying rod 22 or any stirring rod 32. By driving any conveying rod 22 or any stirring rod 32 to rotate, under the action of the transmission gear 7, the other conveying rod 22 or stirring rod 32 rotates in the opposite direction, thereby realizing that the two conveying rods 22 and the two stirring rods 32 can rotate in opposite directions.
[0040] The transmission gear 7 of this embodiment is located outside the corresponding conveying shell 21 or stirring shell 31, and each conveying rod 22 and stirring rod 32 is provided with a coupling 73, and the coupling 73 is located outside the corresponding conveying shell 21 or stirring shell 31. For the conveying rod 22 and stirring rod 32 directly connected to the reducer 72, the driving motor 71, the reducer 72, the transmission gear 7, and the coupling 73 are sequentially arranged in the direction close to the corresponding conveying shell 21 or stirring shell 31; for the driven conveying rod 22 and stirring rod 32, the transmission gear 7 and the coupling 73 are sequentially arranged in the direction close to the corresponding conveying shell 21 or stirring shell 31.

The connecting pipe 4 is provided with a plurality of liquid discharge holes 401, and the liquid discharge holes 401 communicate with the liquid storage tank 8; the water adding pipe 41 is conductively connected to the liquid storage tank 8. The water adding pipe 41 of this embodiment is provided with a regulating valve 411 to control the water addition amount according to the material flow rate of the connecting pipe 4. The liquid storage tank 8 is a hollow ring-shaped structure. After the water discharged from the water adding pipe 41 enters the liquid storage tank 8, it is discharged into the connecting pipe 4 through the liquid discharge holes 401.
[0042] A heating pipe 81 is fixedly arranged in the liquid storage tank 8. Under the action of the heating pipe 81, the water in the liquid storage tank 8 can be heated to avoid the inability to produce due to low temperature during production in winter in the north.
[0043] In this embodiment, the feeding conveyor belt 11, the discharging conveyor belt 12, the regulating valve 411, the cleaning motor 63, the driving motor 71, and the heating pipe 81 can be controlled by a PLC controller to complete the automatic pre-wetting process of the wood chips.
[0044] The operation process of the wood chip pre-wetting device in this embodiment is as follows:
[0045] The wood chips are conveyed to the screen 51 through the feeding conveyor belt 11. After the impurities are removed, the wood chips enter the conveying shell 21 through the feeding frame 5. The two conveying rods 22 push the wood chips towards the discharge port. The wood chips are evenly discharged through the discharge port and enter the connecting pipe 4. At the same time, the water discharged from the water adding pipe 41 enters the liquid storage tank 8 and is then discharged into the connecting pipe 4 through the liquid discharge holes 401 to uniformly pre-wet the wood chips in the connecting pipe 4.
[0046] After the wood chips enter the stirring mechanism, under the action of the spiral blade 321 at the front end of the stirring rod 32, the wood chips move along the direction close to the discharge port 311.
