[0001] The utility model relates to the technical field of wood processing equipment, and specifically discloses a wood chipping device. Background Art

[0002] A wood chipper is a special equipment for producing wood chips. Its basic working principle is to cut round wood into required wood chips through an internal rotor and blades, and it is mostly used in forestry processing and wood recycling and other fields. According to different working methods, wood chippers can be divided into disc wood chippers and drum wood chippers.

[0003] Chinese Patent No. CN211389248U discloses an efficient wood chipper. For this efficient wood chipper, the end of the discharge pipe is a horizontal pipe, and an outer edge is provided at the end of the discharge pipe. The end of the discharge pipe is connected with a quick-installation diversion mechanism. The quick-installation diversion mechanism includes a transverse pipe, a longitudinal pipe, a diversion cover, a fixed edge and a locking mechanism. One end of the transverse pipe extends into the inner cavity of the end of the discharge pipe, and the other end is communicated with the upper end of the longitudinal pipe. The lower end of the longitudinal pipe is communicated with the diversion cover. A fixed edge is provided on the outer wall of the end of the transverse pipe extending into the inner cavity of the end of the discharge pipe. The length of the fixed edge is greater than the length of the outer edge, and the width of the fixed edge is greater than the width of the outer edge. Long strip-shaped openings are provided at the four corners of the fixed edge, and locking mechanisms are installed in the long strip-shaped openings. The utility model conducts unified diversion and collection of the wood chips after slicing, which is convenient for realizing rapid and unified treatment on the premise of preventing the wood chips from being contaminated.

One end of the ash collection tank 31 is provided with a second discharge port 311, and a second baffle 32 is arranged inside the second discharge port 311. Both ends of the second baffle 32 are clamped and connected to both sides of the second discharge port 311 respectively. The end of the ash collection tank 31 far from the second discharge port 311 is connected with a handrail 34. A plurality of second universal brake wheels 33 are connected below the ash collection tank 31. One end of the ash collection tank 31 abuts against the second limiting plate 23.

[0029] As Figure 1 and Figure 2 shown, two first limiting plates 11 are symmetrically connected to one end of the chipper body 1 close to the screening mechanism 2, which is convenient for the position of the idle screening mechanism 2 and saves the time for aligning the screening mechanism 2 and the chipper body 1.

[0030] As Figure 1 , Figure 3 and Figure 4 shown, both sides of one end of the bracket 21 abut against the two first limiting plates 11 respectively, which helps to accurately limit the position of the screening mechanism 2. A through hole 211 is formed on one side of the bracket 21 to facilitate the output end of the motor 28 to pass through. First long holes 212 and second long holes 213 are formed on both sides of the bracket 21 to facilitate the first connecting shaft 242 and the second connecting shaft 243 to pass through. A plurality of first universal brake wheels 22 are connected below the bracket 21 to facilitate the adjustment and fixation of the position of the screening mechanism 2. A second limiting plate 23 is connected below one end of the bracket 21 close to the chipper body 1, which can limit the position of the ash collection mechanism 3 and save the alignment time of the ash collection mechanism 3 and the screening mechanism 2. A screening basket 24 is arranged inside the bracket 21 to facilitate the temporary storage of wood chips and the cleaning of wood chips mixed with sawdust.

[0031] As Figure 1 , Figure 3 and Figure 5As shown, a first discharge port 241 is provided at one end of the sieve basket 24 away from it, facilitating the discharge of sufficient wood chips in the sieve basket 24 through the first discharge port 241. A first baffle 25 is provided inside the first discharge port 241, which can prevent wood chips from falling out of the sieve basket 24 during the screening process, so as to concentrate the wood chips in the sieve basket 24. Both ends of the first baffle 25 are snap-connected to both sides of the discharge port, facilitating the disassembly and assembly of the first baffle 25. First connecting shafts 242 and second connecting shafts 243 are provided on both sides of the sieve basket 24. The first connecting shafts 242 and second connecting shafts 243 respectively penetrate into the first long holes 212 and second long holes 213. The first connecting shafts 242 and second connecting shafts 243 are respectively slidably connected to the first long holes 212 and second long holes 213, providing support for the sieve basket 24 while restricting the moving direction of the sieve basket 24.

[0032] As Figure 1 , Figure 3 and Figure 6 As shown, a connecting rod 26 is rotatably connected to the outside of one of the first connecting shafts 242.

During the movement, the second connecting shaft 243 reciprocates in the second long hole 213, so that the screening basket 24 reciprocates smoothly. Put the wood to be chipped into the chipper body 1 from the feeding end of the chipper body 1. The crushed wood chips mixed with sawdust are discharged into the screening basket 24 from the discharge pipe. During the reciprocating movement of the screening basket 24, the sawdust with a smaller diameter leaks into the dust collecting tank 31 through the sieve holes, and the wood chips with a larger diameter remain in the screening basket 24.

[0034] When a sufficient amount of wood chips are collected in the screening basket 24, turn off the chipper body 1, use the controller 29 to turn off the motor 28, release the brake of the second universal brake wheel 33, pull out the dust collecting tank 31 from under the screening mechanism 2, move it to the sawdust storage place, pull out the second baffle 32 from the second discharge port 311, clean the sawdust out of the dust collecting tank 31 from the second discharge port 311, then reset the second baffle 32 and move the dust collecting mechanism 3 to the end close to the first baffle 25. Pull out the first baffle 25 from the first discharge port, discharge the wood chips from the first discharge port and let them fall into the dust collecting tank 31, and transfer them to the wood chip storage point through the dust collecting tank 31. Or directly release the brake of the first universal brake wheel 22, transfer the screening mechanism 2 together with the wood chips to the wood chip storage point, and then pull out the first baffle 25 from the first discharge port 241 to clean the wood chips to the wood chip storage point.
