Description

Technical Field

[0001] The utility model belongs to the technical field of chippers, in particular to a drum chipper. Background Art

[0002] Drum chipper is a traditional product. It has been widely used by domestic and foreign merchants for many years due to its superior performance, high quality and high cost performance. Drum chipper is a special equipment for preparing high-quality wood chips. It is suitable for paper mills, particle board mills, fiberboard mills, wood chip production bases and wood chip export bases. It can cut logs and small-diameter wood into high-quality industrial wood chips with uniform length, smooth cut and uniform thickness. It can also cut branches, boards, etc.

[0003] The wood is fed into the chipper through the feed port. When the wood touches the chipping blade, it is chipped as the chipping disc rotates at high speed. The cutting mechanism is a rotating drum with several flying knives installed on it. The flying knives process the wood into wood chips as they rotate. There are multiple square through holes on the outer edge of the drum. The qualified chips cut down fall through the mesh holes and are discharged from the bottom. The large chips will be cut again in the machine.

[0004] The Chinese utility model patent with publication number: CN216578390U discloses an efficient drum chipper for cutting wood, and its scheme includes: a chipper body and a discharging device, the discharging device is installed at the discharging port of the chipper body, the discharging device includes a mounting plate, a discharging pipe, a discharging plate and a telescopic rod, the mounting plate is fixedly mounted on the discharging port, and the lower part of the mounting plate is fixedly connected to the discharging pipe and the telescopic rod, the discharging pipe and the telescopic rod are arranged in parallel, and the discharging pipe is communicated with the discharging port, the bottom of the discharging pipe is fixedly connected to the discharging plate, the bottom of the telescopic rod is fixedly connected to the positioning block, and the side of the discharging plate close to the telescopic rod is provided with an adjusting block, the adjusting block is rotatably connected to the positioning block, and is locked by bolts, and the discharging plate is buckled on the receiving barrel; the technology can guide the cut wood into the receiving barrel through the discharging device, avoid wood ash flying out of the discharging port, and the discharging device can adjust the length and angle.

[0005] However, in actual use, after the wood is cut, it will be mixed with wood ash and enter the receiving barrel. In the receiving barrel, the wood and the wood ash cannot be separated. In this way, the wood ash will be carried out in the subsequent process of taking the wood out of the receiving barrel, which will still affect the health of the workers. Therefore, the technology needs to be improved. Utility Model Content
