Description

Technical Field

[0001] The utility model relates to the technical field of wood chipper rotors, and specifically discloses a wood chipper rotor. Background Art

[0002] Wood chipper is a special equipment used to produce wood chips. It is also called wood slicer and belongs to one of the wood processing equipment series. This equipment is widely used in the material preparation section of the production process of textile, papermaking, pulping, wood-based panels and other industries. Wood chipper is mainly composed of feeding device, pressing device, cutting system, discharging device, electronic control system and other parts. The working principle is to cut the wood into thin slices through the high-speed rotating blade contact with the wood to be processed. The feeding device pushes the wood into the cutting system, and the pressing device pushes the wood down at a certain speed to ensure that the wood keeps a certain distance from the cutting machine head. The cutting system uses high-speed rotating blades to cut the wood into thin slices, which are then pushed out of the machine by the discharging device.

[0003] The cutting system of the existing chipper, such as the patent announcement number CN208323687U, discloses a new chipper, mainly to provide a chipper of a new structure, in which the cutting rotor assembly includes a central axis connecting sleeve arranged on the central axis of the cutting rotor assembly, and a plurality of adjustable cutter disc bodies are arranged on the central axis connecting sleeve.

[0004] The material storage chamber of the adjustable cutter disc body is arranged in front of the chipper, but the wood is easy to hit the inner wall of the material storage chamber when feeding. In this process, the wood is easy to break and then cut by the chipper, which affects the wood chip yield and causes more broken materials. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a wood chipper rotor to solve the problem that the material storage chamber of the adjustable cutter disc body is arranged in front of the chipper moving knife, but the wood is easily rubbed against the inner wall of the material storage chamber during feeding. In this process, the wood is easily broken and then cut by the chipper moving knife, which affects the wood chip yield and causes a lot of broken materials.

[0006] To achieve the above purpose, the technical solution of the utility model is:

When wood is fed, it can enter the material storage chamber, reducing the breakage of the wood and ensuring that the wood is cut by the chipper blade group. The cut wood chips are thrown out from the rear end of the chipper blade group, thereby improving the wood chip yield rate and reducing the broken materials.

[0008] Preferably, the material storage chamber includes a plurality of partitions evenly arranged between two mounting plates; the partitions are fixedly arranged on the main shaft; a housing is fixedly arranged between two adjacent partitions and between the partition and the mounting plate; the housing cross section is generally concave; and the open end of the housing is arranged below the chipping knife group. The arrangement of the partitions reduces the collision of the cut wood chips in the housing, avoids the movement of the wood chips along the axial direction of the main shaft, further ensures the wood chip yield rate, and reduces the fragmentation.

[0009] Preferably, an arc-shaped baffle is fixedly arranged between two adjacent shells along the circumferential direction, so as to prevent the cut wood chips from entering between the two shells and ensure the wood chip yield.

[0010] Preferably, the partition plate is provided with a clearance groove in cooperation with the chipping knife set, so as to facilitate the arrangement of the chipping knife set on the mounting plate.

[0011] Preferably, a side plate on one side of the housing is arranged at an angle, and the side plate is arranged at the blade head end of the chipping knife group, so as to facilitate the wood chips to enter the housing.

[0012] Preferably, the chipping knife group includes a knife seat plate; the knife seat plate has an overall L-shaped cross-section; a blade is arranged on the knife seat plate; the blade is fixed to the knife seat plate by bolts; a threaded hole is arranged on the knife seat plate; a screw is arranged in the threaded hole; and the end of the screw contacts the blade.

[0013] Preferably, a pressure plate is arranged on the blade, and the bolt passes through the pressure plate and the blade and then is threadedly arranged on the blade seat plate, so as to ensure the stability of the blade arrangement.

[0014] Preferably, a protective plate is fixedly arranged on the knife seat plate; the protective plate is arranged in cooperation with the end of the screw to avoid damage to the wood chips by the screw, thereby further ensuring the yield rate of the wood chips.

[0015] The beneficial effects of the utility model are as follows: when wood is fed, it can enter the material storage chamber, reducing the breakage of the wood and ensuring that the wood is cut by the chipper group. The cut wood chips are thrown out from the rear end of the chipper group, thereby improving the wood chip yield rate and reducing broken materials. BRIEF DESCRIPTION OF THE DRAWINGS
