Abstract

The invention belongs to the technical field of a biomass crushing machine, in particular relates to a device for finely crushing biomass suitable for branches and straws, and solves the problem that the prior device for crushing biomass discharges rough material and has high energy consumption and low yield. The device for finely crushing biomass comprises a bracket assembly, a feeding mechanism and a crushing mechanism. The crushing mechanism comprises a strip hard stationary knife and a movable knife combined knife roll with the axial line in parallel with knife-edge line of the hard stationary knife. The included angle between the knife-edge line of the hard stationary knife and the feeding direction of the feeding mechanism is 20-30 degrees. The invention has the beneficial effects that 1, the device has a simple structure, low manufacturing cost and convenient maintenance; 2, the device has strong applicability and is capable of crushing all straws and finely discharging material once only no matter the straws are dry or wet; 3, the device is environment-friendly, saves energy and has high yield, and the cutter has long service life.

Description

technical field [0001] The invention belongs to the technical field of biomass pulverizing machinery, in particular to a biomass fine pulverizing device suitable for branches and straws. Background technique [0002] my country has a vast land and abundant biological straw resources. A large number of straw green resources are produced every year, but they are not well utilized. People burn a large amount of straw, which not only pollutes the environment, but also may cause fires sometimes. However, grassland animal husbandry and dairy cattle breeding require a large amount of straw fine powder as feed. The use of fine straw raw materials in various wood-based panels and papermaking industries can greatly reduce costs. At present, there are only grass cutters in the domestic and foreign markets. The output is rough, high energy consumption and low output, which is far from meeting the needs of people and society. Contents of the invention [0003] In order to solve the p...
