Background

Agriculture and forestry waste, including both tree trunks and branches, and also fallen leaves, weeds and crop stalks, generally requires different crushers for crushing both trunks and branches, as the hardness of the trunks and branches is different from that of the fallen leaves, weeds and crop stalks. Such as wood mills are commonly used for materials with greater wood branch hardness; whereas straw crushers are commonly used for softer materials such as crop straw, fallen leaves and weeds. This requires the prior classification of soft and hard materials such as tree branches and weeds, straw fallen leaves and the like, and then crushing. Otherwise, the soft materials such as fallen leaves, weeds and the like which are encountered by the wood grinder are directly sprayed out of the wood grinder without grinding.

This is mainly caused by the different structures of the crushing cutters of the wood crusher and the straw crusher. At present, a cylindrical rotary knife roller is mainly adopted for fixing two blades which are mutually formed at 180 ℃, hard materials such as wood and the like are cut rapidly, and then the blades which rotate at high speed are continuously collided to achieve the purpose of crushing, so that the structure is suitable for crushing hard and brittle materials such as wood and the like; the crushing cutter of the straw crusher is a group of hammer sheets, soft materials such as leaves, straws, weeds and the like enter the crushing chamber after being cut off by the cutter, after the hammer sheets rotating at high speed are hit and crushed, the crushed materials continuously pass through the hammer sheets, the toothed plate and the sieve sheets along the outer edge of the rotor under the driving of air flow, and the materials are rapidly crushed by the hitting, collision and friction of the hammer sheets, the toothed plate and the sieve sheets. Therefore, in order to obtain a good pulverizing effect, it is necessary to separate hard and soft materials such as agricultural and forestry waste in advance and then pulverize them by using an appropriate pulverizing device.
