Description

Straw recycling system

Technical Field

The invention belongs to the technical field of straw recycling, and particularly relates to a straw recycling system.

Background

Nowadays, various circles of society advocate environmental protection, and China is used as a big agricultural country and pays more attention to environmental protection; in the rural areas in the past, crop straws can not be reused, so most farmers select to burn on the spot, the environmental pollution is great, along with the development of the society, environment protection is advocated today, various crop straw recycling equipment is more and more, but most of the currently adopted straw recycling equipment smashes the straws, and the straws can be directly returned to the field after being smashed or used as feed and the like; for example, patent application No. CN201811439094.7 discloses a method for recycling crop straws, which cuts crop straws by a material cutting hob of a straw recycling device, and divides the whole straws into small straw sections; the straw sections fall in front of the material pushing plate along the steel plate, and the material pushing plate is driven by the first air cylinder to push the straw sections to the lower part of the material grinding module; after the straw section reachd the material module below of grinding, the shovel flitch rolls the straw section in sending to the material module of grinding with the straw section shovel, and then thoroughly pulverizes the straw, improve still field efficiency through improving crushing degree, nevertheless smash still the field with the straw, the straw after smashing on the one hand is easily raisd and then the polluted air by the wind, and cause the conflagration easily, the straw still field will be degraded through very long period of time after, obviously this is that the cultivation of crops is relatively delays.

In silicate report 34, fourth phase 2015.4, a document of "current research situation of straw resource application in concrete" is proposed, which indicates that the straw doped in concrete can play a role in toughening and improving the compressive strength of concrete, and can play a role in improving the frost resistance and durability of concrete, and obviously, the recovery and application of the straw in concrete is a good choice; however, when ordinary directly segmented straws are mixed into concrete, on one hand, the binding capacity of binding materials in the concrete and the straws can be influenced due to the fact that the surfaces of the straws are too smooth, and further the workability and the water retention of the concrete are poor, on the other hand, if the straws are large in diameter and inevitably large in hardness, the straws cannot be well filled in the concrete, but the straws play a role in building similar to coarse aggregates, so that the consumption of sand and stone is reduced, or the consumption of cement is greatly increased, obviously, the former can reduce the strength of the concrete, and the latter is not economical.
