[0031] Reference Figures 1 to 6 This utility model proposes a woody raw material crushing device 100.

[0032] In this embodiment of the utility model, the woody raw material crushing equipment 100 includes a frame 10; a mounting housing 20 installed on the frame 10, forming a crushing chamber 20a and a feed and discharge port 20c communicating with the crushing chamber 20a; a crushing assembly including a driving component 31, a driving shaft 32, multiple baffles 33 and multiple moving blade groups 34, the driving shaft 32 being disposed in the crushing chamber 20a and rotatably connected to the mounting housing 20, the driving component 31 being installed on the frame 10 and being drively connected to the driving shaft 32, the multiple baffles 33 being spaced apart along the length direction of the driving shaft 32, the multiple moving blade groups 34 being connected to the multiple baffles 33 and spaced apart along the circumference of the driving shaft 32; and a fixed blade assembly including multiple fixed blade edges 41, the multiple fixed blade edges 41 being evenly spaced along the sidewall of the crushing chamber 20a.

[0033] Specifically, the frame 10 is formed by splicing metal profiles, and the mounting housing 20 is made of sheet metal material, which is welded or fixed to the frame 10 with screws. The mounting housing 20 has a cavity structure, forming a crushing chamber 20a and a feed inlet 20b and a discharge outlet 20c that connect to the crushing chamber 20a. Two mounting bearings are provided on opposite sides of the mounting housing 20, and the opposite ends of the drive shaft 32 are respectively inserted into the bearing holes of the mounting bearings.

[0034] The driving component 31 of the crushing assembly (not shown) includes a drive motor 311, a driving wheel 312, a driven wheel 313, and a transmission belt. The drive motor 311 is fixed to the frame 10 by screws or other means and is spaced apart from the mounting housing 20. The driving wheel 312 is driven by the output shaft of the drive motor 311. The driven wheel 313 is fitted onto one end of the drive shaft 32. The transmission belt connects the driving wheel 312 and the driven wheel 313. Driven by the drive motor 311, the driving wheel 312 drives the driven wheel 313 to rotate via the transmission belt. The structure is simple and easy to install and maintain. Multiple baffles 33 are spaced apart along the extension direction of the drive shaft 32.

[0035] Please see again Figure 6 Multiple moving blade assemblies 34 are connected to multiple baffles 33 and are spaced apart circumferentially along the drive shaft 32. Specifically, this application provides four moving blade assemblies 34, each consisting of a mounting rod 341, multiple straight-moving blades 342, and multiple curved-moving blades 343. The mounting rod 341 is detachably connected to the multiple baffles 33, and the multiple straight-moving blades 342 and multiple curved-moving blades 343 are staggered along the extension direction of the mounting rod 341. It should be noted that in this application, both the straight-moving blades 342 and the curved-moving blades 343 are rotatably connected to the mounting rod 341. That is, when the mounting rod 341 rotates, under the action of centripetal force, the straight-moving blades 342 and the curved-moving blades 343 rotate relative to the mounting rod 341, striking the woody raw material to achieve a crushing effect. The end of the curved-moving blade 343 is inclined towards the discharge port 20c, which can delay the residence time of the woody raw material in the crushing chamber 20a, thereby improving the crushing effect.

[0036] In this application, woody raw materials are fed into the crushing chamber 20a through the feed inlet 20b. The drive unit 31 drives the drive shaft 32 to rotate, so that multiple baffles 33 and multiple moving blade groups 34 rotate within the crushing chamber 20a. The moving blade groups 34 continuously strike the woody raw materials to crush them. During the striking process, since multiple fixed blade edges 41 are provided in the crushing chamber 20a, as the woody raw materials rotate and are crushed, the multiple fixed blade edges 41 can also simultaneously react on the woody raw materials. Thus, without increasing the power or expanding the crushing chamber 20a, the crushing of the woody raw materials is more complete and fine, and the crushing effect is better.

[0037] Furthermore, the fixed blade assembly includes multiple connectors (not shown in the figure), which can be screws or pins. The fixed blade edge 41 has multiple connecting holes, and the sidewall of the crushing chamber 20a has multiple mounting holes. Correspondingly, the connecting holes and mounting holes are set as screw holes or pin holes. The connectors pass through the connecting holes and mounting holes to connect the fixed blade edge 41 and the mounting housing 20. In this application, the cross-section of the fixed blade edge 41 is rectangular or triangular, and it is made of metal profile. It is machined to have connecting holes, and the fixed blade edge 41 and the mounting housing 20 are connected by the connectors, which provides a stable connection and facilitates disassembly and assembly. Of course, the fixed blade edge can also be integrally formed with the mounting housing 20 or welded to the mounting housing 20, which is not specifically limited here.

[0038] Furthermore, the moving blade assembly 34 also includes fastening screws (not shown in the figure). The baffle plate 33 has limiting holes that penetrate its opposite side surfaces. The diameter of the limiting holes is adapted to the diameter of the mounting rod 341, so that the mounting rod 341 can pass through multiple limiting holes on multiple baffle plates 33. The opposite ends of the mounting rod 341 are machined with fastening threaded holes. Two fastening screws are connected to the fastening threaded holes and abut against the surface of the baffle plate 33 to fix the mounting rod 341 and the baffle plate 33.

[0039] In one embodiment of this utility model, a material control rib 21 is further formed on the side wall of the crushing chamber 20a, and the material control rib 21 is disposed adjacent to the discharge port 20c. In this application, the material control rib 21 is used to stop the larger particle size of the woody raw material after crushing, allowing it to continue to be crushed. By setting the material control rib 21, the crushing effect of the woody raw material crushing equipment 100 is further improved.

[0040] Furthermore, the crushing assembly also includes an impeller 35, which is drivenly connected to the drive shaft 32 and corresponds to the discharge port 20c. When the impeller 35 rotates, an airflow is formed in the crushing chamber 20a. This airflow guides the crushed woody raw material from the feed port 20b to the discharge port 20c, thus completing the discharge of the woody raw material. In this application, the impeller 35 is connected to the drive shaft 32, eliminating the need for additional drive structures and simplifying the structure of the woody raw material crushing equipment 100.

[0041] In this invention, the feed inlet 20b is flared outwards from the side of the mounting housing 20 to facilitate the user in feeding woody raw materials into it; the mounting housing 20 includes a magnet 22, which is located at the discharge port 20c to attract metal substances when woody raw materials are fed in, thereby preventing metal substances from damaging the equipment.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
