Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural mechanical equipment, in particular to a straw softening and crushing integrated machine. Background Art
[0002] The existing straw crusher can crush wheat straw, grass straw, bean straw, flower firewood and other combustible crop straws, avoiding the wasteful burning of these crop straws, thus protecting the environment well and effectively developing renewable energy.
[0003] At present, the pulverizers on the market generally have a blade shaft inside. A single pulverization can only simply pulverize the straw. The lengths and sizes of the pulverized straw vary. The pulverization of the straw is completely dependent on the inertia of the blade. The pulverization force is relatively small. For materials with harder straws such as corn stalks and tall grass, there is no pre-softening function. This will lead to incomplete pulverization, which brings great trouble to the pulverization work and may require re-pulverization. If these hard grass straws can be softened in advance during pulverization, they can be fully pulverized to achieve the best effect of straw pulverization. The existing pulverizers increase the workload, reduce the efficiency of pulverization, and cannot meet the needs of the majority of farmers. Summary of the invention
[0004] The utility model aims to provide a straw softening and pulverizing machine with a reasonable structure, which can soften and coarsely pulverize straw before finely pulverizing it, and combines the softening and coarse pulverizing with the fine pulverizing in structure, thereby achieving sufficient pulverizing, good straw pulverizing effect and high efficiency.
