Embedded differential double-helix type green feed straw crushing and conveying device

Abstract

The invention discloses an embedded differential double-helix type green feed straw crushing and conveying device. The device comprises a stander, an auger mechanism, a spraying mechanism and a throwing mechanism, wherein the auger mechanism is fixed at the front part of the stander, the spraying mechanism is fixed above the rear part of the stander, the throwing mechanism is fixed below the rear part of the stander, rigid crushing blades are fixed outside the radial direction of a roller, flexible conveying blades are fixed on the inner side of the rigid crushing blades so as to form an external helix auger, rigid conveying blades fixed on the roller form an internal helix auger, and the rotation speeds of the internal helix auger and the external helix auger are different, so that the grading crushing and conveying of straws are realized; discharging holes are formed in the rigid crushing blades and the flexible conveying blades according to the same vortex path line, so that the probability of adhesion and blockage in the conveying process is lowered; and arc-shaped stirring fingers are formed in throwing blades, so that the grabbing capacity and the throwing capacity are enhanced. According to the embedded differential double-helix type green feed straw crushing and conveying device, the synchronous differential crushing and conveying of green feed straws are realized, the probability of winding and blockage of the straws is reduced, and the crushing efficiency and the conveying efficiency are improved.

Description

Technical field [0001] The invention relates to an agricultural machine, in particular to a nested differential double spiral green forage straw crushing and conveying device. Background technique [0002] Green forage straw is an important target of the national strategy for reforming grain and is also a key link to improve the comprehensive value of crop solid waste; the green forage straw crushing and conveying device is used to crush and transport high-moisture straw, and it is the key equipment for the entire mechanization of agricultural production. . Existing green forage straw production equipment is mainly divided into cutting, feeding, crushing, conveying, etc., and each type of equipment has a single function, resulting in a complex production and harvesting process, high harvesting costs, and long harvesting cycles for green forage straw. The main purpose of the forage straw after harvest is animal husbandry feed. Due to the high water content and incomplete crushing...

Problems solved by technology

The existing green forage straw production equipment is mainly divided into cutting, feeding, crushing, conveying and other types, and each type of equipment has a single function, which leads to complex harvesting process, high harvest cost and long harvest cycle for green forage straw production. In addition, green forage straw production The main purpose of feed straw after harvest is animal husbandry feed. Due to the high moisture content and incomplete crushing, the harvested green feed straw will become moldy during short-term storage and transportation, reducing its feed application value.

The main problem of the green straw crushing device is that the crushing is not complete, and it is easy to cause entanglement and blockage. The main problem of the green straw conveying device is that the material travels fast, the feeding and throwing speed is slow, and the green straw is inside the conveying device. prone to clogging

From the perspective of technical characteristics, the existing green straw conveying device still uses the traditional screw auger structure, and the crushed straw and unground straw are conveyed at the same speed, resulting in uneven crushing; the crushing mechanism and conveying mechanism of green straw Distributed in different parts of the whole machine, which increases the production cost and the volume of the whole machine, and limits the development of green forage straw combined harvesting machinery
