Counter-rotating double-roller anti-winding banana straw crushing and returning machine

Abstract

The invention provides a heterodromous double-roller anti-twining banana straw smashing and returning machine. The heterodromous double-roller anti-twining banana straw smashing and returning machine comprises a machine frame, a suspension device hinged to the machine frame, a transmission device installed on the front side of the machine frame, a smashing device located in the machine frame, and a depth limiting device installed at the bottom of the machine frame. The smashing device comprises a front smashing knife roller and a rear smashing knife roller which are heterodromous. The front smashing knife roller and the rear smashing knife roller are provided with flail knives, and the flail knives are provided with rotatable double-blade straight knives with wavy-line-shaped blades. The heterodromous double-roller anti-twining banana straw smashing and returning machine is simple and compact in overall structure, fewer in twined fiber and high in smashing efficiency, and smashing and returning of banana straw can be efficiently finished with low energy consumption.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an anti-wrapping double-roller banana straw crushing and returning machine. Background technique [0002] Banana straw is the main by-product of banana production areas, and the annual production of banana straw in the country is as high as more than 30 million tons. At present, the vast majority of banana planting areas still use the traditional method to deal with banana pseudostems: first remove the leaves and tail tips, and then manually cut them down and transport them to open fields to rot naturally or burn them after drying up after about 2 months. The mode of processing banana pseudostem like this is not only labor-intensive, production efficiency is low, production cost is high, and can cause environmental pollution, resource waste. [0003] At present, the main factor limiting the low utilization rate of banana straw is the lack of efficient ...

Problems solved by technology

The mode of processing banana pseudostem like this is not only labor-intensive, production efficiency is low, production cost is high, and can cause environmental pollution, waste of resources

[0003] At present, the main factor limiting the low utilization rate of banana straw is the lack of efficient banana straw processing equipment

Due to the characteristics of thick banana stalks, high moisture content and rich fiber, the existing banana straw crushing and returning machines can only achieve relatively thorough crushing of banana straws through multiple operations, and the crushing knife roller and the crushing knife are easy to wind up a lot during the operation. of banana stalk fibers, resulting in increased energy consumption and reduced efficiency
