Crawler type two-stage straw pulverizer

Abstract

The invention discloses a crawler type two-stage straw pulverizer. The crawler type two-stage straw pulverizer comprises a rack, a cut-off device, a double-screw feeding device, a dewatering device, afirst-stage smashing device, a second-stage smashing device, a transmission device, a walking device, an engine and a cab. The cut-off device, the double-screw feeding device, the dewatering device,the first-stage smashing device and the second-stage smashing device are arranged between the cab and the walking device, and sequentially arranged from the head end of the rack to the tail end of therack. The engine is fixed to the top of the walking device, and power of the engine is transferred to the cut-off device, the double-screw feeding device, the dewatering device, the first-stage smashing device and the second-stage smashing device through the transmission device. Straw sequentially passes through the cut-off device, the double-screw feeding device, the dewatering device, the first-stage smashing device and the second-stage smashing device, the procedures of cutting off, feeding, dewatering, first-stage smashing and second-stage smashing are completed, the smashing particle size of the thick straw can be increased, the crawler type two-stage straw pulverizer is suitable for banana straw smashing and mulching of main producing areas of banana and promotion of income increaseof banana farmers.

Description

Technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a crawler-type secondary straw crusher. Background technique [0002] In 2014, the total area of ​​banana plantation in China was about 402,300 ha 2 , Banana stalks are a large amount of agricultural waste after banana harvest. If the mass ratio of banana stalk waste to banana production is 2.4, about 21 million tons of banana stalk waste will be generated every year. Due to the high moisture content of the banana stems, the thick and scattered stems, the high cost of manual treatment and the lack of suitable mechanized stem processing equipment, the disposal of banana stem waste has become a major problem. In addition to part of the banana stem waste can be used as fertilizer, it is mostly piled up in the field for incineration or natural decay. This not only takes up valuable land resources and causes serious environmental pollution, it affects the re-cultivation of b...

Problems solved by technology

[0004] The traditional straw grinder pushes down the straw and pulls it with a tractor, and crushes the straw with a knife at the bottom. It has a better crushing effect on small stems, such as corn straw, but the crushing effect on banana straw with thick stems is not good. Not very good, thick stalks have higher requirements for crushing tools, and one-time crushing cannot completely cut off the banana stalks, resulting in most stalks being broken and connected, making the straws completely rot in the ground for a long time, which has a certain impact on soil fertilization , and the tractor engine power is limited
