Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] Such as Figure 2 to Figure 6 As shown, a wear-resistant knife drum used in a drum chipper provided in the figure includes four circumferentially evenly distributed lining plates 40 connected to each other, four circumferentially uniformly distributed flying knife support seats 100 and fixed on the lining plate 40 The end plates 80 at both ends have a shaft hole 81 in the center of the end plate 80 , wherein each flying knife support seat 100 is connected between two adjacent lining plates 40 . An arc-shaped cutting groove 51 is also provided on the lining plate 40 of the knife drum adjacent to the flying knife support seat 100 .

[0021] Each flying knife support seat 100 is L-shaped, which has a straight portion 110 and a transverse port...

Abstract

The invention discloses a method for preventing a knife drum from being abraded. A sunken abrasion-resisting plate installation plane is placed on an inclined plane part corresponding to length direction of an arc-shaped cutting groove, wherein the inclined plane part is placed at the outer end of a fly-cutter support seat. A bolt hole is formed in the fly-cutter support seat corresponding to vertical direction of the abrasion-resisting plate installation plane, and an abrasion-resisting plate fixing bolt is placed in the bolt hole and is in threaded connection with an abrasion-resisting plate. The abrasion-resisting plate is installed on the abrasion-resisting plate installation plane, the surface of the abrasion abrasion-resisting plate is aligned to the inner surface of the arc-shaped cutting groove to jointly form a cutting groove. When timber enters the cutting groove, the timber scrapes and rubs the abrasion-resisting plate and is not directly contacted with the fly-cutter support seat. The method for preventing the knife drum from being abraded has the advantages of protecting the knife drum from not being abraded under a situation of not affecting cutting processes, effectively prolonging service life of the knife drum and saving labor power and material resources. The invention further discloses a knife drum structure capable of preventing abrasion of a drum type chipping machine.

Description

technical field [0001] The invention relates to a knife drum of a drum chipper, in particular to a method for preventing the wear of the knife drum and an anti-wear knife drum structure of the drum chipper. Background technique [0002] Drum chipper is a special equipment for preparing wood chips, widely used in paper mills, particleboard factories, fiberboard factories and wood chip production bases. It can cut logs, branch wood, small-diameter wood, etc. into industrial wood chips of certain specifications; the drum chipper is composed of a frame, a knife drum, a feed roller group, a casing, an electric control system and other parts. The overall structure is compact and reasonable, the operation is simple, the production capacity is large, and the raw material adaptability is strong. It is an ideal equipment for producing high-quality wood chips. [0003] The working principle of the drum chipper is that the motor drives the knife drum to rotate through the belt drive. T...
