However, in the process of crushing wood chips in the crusher in the prior art, there will still be some incompletely crushed wood chips, which may easily lead to the wood chips being unable to be crushed more completely. The incompletely crushed wood chips will be mixed with the crushed wood chips, which may easily affect the later processing efficiency of the wood chips. For this reason, we propose a wood chip processing crusher. Utility Model Content

[0021] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.
[0022] Example:
[0023] like Figure 1-Figure 4 As shown, a wood chip processing crusher comprises a crushing box 1 and a driving box 2 fixedly connected to one side, a driving assembly is arranged inside the driving box 2, a No. 1 rotating rod 3 and a No. 2 rotating rod 4 are rotatably connected inside the crushing box 1, a plurality of No. 1 crushing blades 5 are fixedly sleeved on the surfaces of the No. 1 rotating rod 3 and the No. 2 rotating rod 4 for crushing wood chips, a discharge port 6 is provided on one side of the crushing box 1, a crushing box 7 is fixedly connected to one side of the crushing box 1, two rotating shafts 8 are rotatably connected inside the crushing box 7, one end of the two rotating shafts 8 are both arranged inside the crushing box 7 and fixedly connected to gears 9, a pair of No. 2 crushing blades 10 are fixedly connected on the surfaces of the two rotating shafts 8 for crushing wood chips, and the crushing A screening net 11 is fixedly connected to the inner wall of the crushing box 1. The driving assembly includes a driving motor 15 fixedly connected to one side of the driving box 2 for providing power. The output shaft of the driving motor 15 is fixedly connected to two worms 16 through a coupling. One end surface of the No. 1 rotating rod 3 and the No. 2 rotating rod 4 are fixedly sleeved with a worm wheel 17, which serves as a transmission. The spiral grooves on the surfaces of the two worms 16 are opposite, and one side of the two worm wheels 17 is meshed with the worm 16. The surfaces of the worm 16 and one of the rotating shafts 8 are fixedly sleeved with a pulley 18, and a belt 19 is provided between the two pulleys 18. A discharge pipe is fixed and connected to one side of the crushing box 1, and the inclination angle of the screening net 11 is 35 degrees.
[0024] The working principle of the above technical solution is as follows:
[0025] After placing the wood chips inside the crushing box 1, the driving motor 15 is started to drive the worm 16 to rotate, and the worm 16 drives the two meshing worm wheels 17 to rotate, so that the No. 1 rotating rod 3 and the No. 2 rotating rod 4 can be driven to rotate in opposite directions, so that it is convenient to drive multiple No. 1 crushing blades 5 to rotate, and the wood chips are initially crushed. Then the crushed wood chips fall onto the surface of the screening net 11, and the completely crushed wood chips are filtered through the screening net 11, so that the larger crushed wood chips pass through the inclination of the screening net 11 and fall into the crushing box 7. Through the rotation of the worm 16, the rotating shaft 8 is driven to rotate under the action of the pulley 18 and the belt 19, and the two rotating shafts 8 and the No. 2 crushing blade 10 can be rotated under the action of the two gears 9, so that the incompletely crushed wood chips can be repeatedly crushed, thereby improving the crushing efficiency of the wood chips.
[0026] In another embodiment, if Figure 2 As shown, the internal thread of the driving box 2 is connected with an adjusting screw 12, one end of the adjusting screw 12 is fixedly connected with a swivel 13, one end surface of the No. 2 rotating rod 4 is rotatably sleeved with a mounting sleeve 14, one end of the adjusting screw 12 is rotatably connected to one side of the mounting sleeve 14, the interior of the crushing box 1 is fixedly connected with a sliding rod 20, the surface of the sliding rod 20 is slidably sleeved with two sliding sleeves 21, and one end of the No. 1 rotating rod 3 and the No. 2 rotating rod 4 are both rotatably connected to one side of the sliding sleeve 21.
[0027] By rotating the rotating ring 13, the adjusting screw 12 is driven to rotate, and the installation sleeve 14 and the No. 2 rotating rod 4 are pushed to move under the action of the thread, so that the distance between the No. 1 rotating rod 3 and the No. 2 rotating rod 4 can be adjusted. At the same time, the No. 2 rotating rod 4 drives the sliding sleeve 21 to slide on the surface of the sliding rod 20, which limits the No. 2 rotating rod 4, so that the distance between the multiple No. 1 crushing blades 5 can be adjusted according to the degree of crushing.
[0028] In another embodiment, if Figure 3 As shown, a feeding pipe 22 is fixed and connected to the bottom of the crushing box 7, and an inclined plate 23 is fixedly connected to the inner wall of the crushing box 1.
[0029] The discharge pipe 22 facilitates the discharge of repeatedly crushed wood chips in the crushing box 7, and the inclined plate 23 can be used to improve the discharge of crushed wood chips by an inclined angle.
[0030] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
