Description

Blade assembly of drum chipper Technical Field The utility model belongs to the field of chipper blades, and particularly relates to a blade assembly of a drum chipper. Background The drum chipper is a special device for preparing high-quality wood chips, is well known in terms of excellent product performance, can efficiently and stably cut logs, small-diameter wood and the like into high-quality industrial wood chips with uniform length, smooth cut and uniform thickness, and the blade assembly is a key part in the device and is responsible for cutting logs or wood into wood chips with required specifications; The blade subassembly of drum chipper can produce a large amount of heat in the cutting process, consequently can design the heat dissipation groove on the blade generally, increase the area of contact of blade and air, give off heat to the air through natural convection, but this kind of radiating mode radiating efficiency is slower, and when blade operating time is longer, the speed that heat produced is higher than the radiating rate, produces a large amount of heat because of the friction, leads to the blade overheated, influences its hardness and wearability, reduces the life of blade easily. Accordingly, the present utility model provides a blade assembly for a drum chipper to solve the above-mentioned problems. Disclosure of utility model In order to solve the technical problems, the utility model provides the following technical scheme: The utility model provides a blade subassembly of drum chipper, includes the blade body, the fixed frame has all been dismantled to the both sides of blade body, the ventilation hole has all been seted up to the front end and the rear end of fixed frame inner chamber, one side of ventilation hole inner chamber is provided with the fan, the inner chamber of fixed frame is provided with fixed unit, fixed unit includes the mounting hole, the mounting hole is seted up in the front end and the rear end of blade body top both sides, the through-hole has all been seted up to the front end and the rear end of fixed frame bottom, the inner chamber sliding connection of through-hole has the draw-in column, the draw-in groove has all been seted up to the front end and the rear end at fixed frame inner chamber top, the top of draw-in column extends to the inner chamber of draw-in groove to with the inner chamber block of draw-in groove.
