An efficient and compact straw pressing and coiling device and method

Abstract

The invention discloses an efficient and compact straw compressing and coiling device and method. The device comprises a frame, a power group, a feeding mechanism, a compressing mechanism and a coiling mechanism, wherein the compressing mechanism comprises a driving roll, a pressure belt, a pressure roll, an adjusting roll and a distance adjusting device; the driving roll and the adjusting roll are mounted on the frame; the pressure belt is sleeved to the driving roll and the adjusting roll; the pressure roll is mounted on the frame above the pressure belt; the distance adjusting device is mounted at the two ends of the adjusting roll; the coiling mechanism comprises a coiling bracekt, a coiling shaft, a motor I, a driving belt I and a controller. The device performs compressing through the pressure belt and the pressure roll, ensures that straw pieces are denser and straw rolls are firmer, is convenient for subsequent transportation, realizes the fact that straws are compressed into solid pieces and coiled into rolls, is convenient for subsequent machining and use, and is simple and compact in structure, convenient to mount, low in noise and convenient to use.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a high-efficiency and compact tableting and coiling device and method for rice straw or grass. Background technique [0002] In the past, straw was mainly used as livestock feed, living fuel or accumulated manure. However, with the improvement of living standards and quality of life in vast rural areas, the use of coal and liquefied petroleum gas has gradually become popular, and livestock such as cattle and sheep have also been raised on a large scale. For ordinary farmers, straw has no use, so the phenomenon of burning straw in the field has begun to appear. Straw burning not only causes great pollution to the atmospheric environment, but also is a serious waste of organic resources. The deep processing of straw can be used as pellet feed, edible fungus base material, fuel and industrial utilization of industrial raw materials; at the same time, burning straw ...

Problems solved by technology

The first is to crush the straw and return it to the field when the harvester is harvesting. However, due to the unsatisfactory effect of crushing and the slow degradation rate, it will have an adverse effect on the sowing and growth of the next season's crops. Therefore, the reality is that farmers The land must be sorted out before sowing, and the scattered straw should be cleaned up or burned directly; the second treatment method is to install a baler on the harvester, and bundle the straw at the same time as harvesting. The straw bundles are fluffy and scattered in the field. For subsequent sorting and transportation, because the straw bales occupy a large area and are easy to scatter, it will bring inconvenience to the subsequent centralized transportation

Although there are some straw flaking devices in China, they mainly use the rolling method, the compaction area and compaction time are relatively small, and the compaction quality of straw cannot be guaranteed.
