羊肚菌精量播种机具设计与试验

Design and Experiment of a Precision Seeding Implement for Morel Mushroom

  • 摘要: 针对羊肚菌人工播种过程中劳动强度大、播种均匀性差及菌种易堆积等技术难点,该文设计了一种基于电动控制技术的轻型精量播种机具。该机械装置采用双层式结构,核心部分包括翻料机构、下料装置、链轮传动系统与行走机构,通过两级翻料装置(一级翻料机构与二级旋转盘)协同作用,有效克服了高湿度环境(60%~65%)下菌种易粘连、堵塞及下料不均匀等问题。田间试验结果表明:在15 m/min的作业速度下,机具播种整体表现良好,播种均匀性误差小于10%,未发生堵塞现象;下料口全开状态下,播种量稳定维持在1.0±0.1 kg/m2,各项性能指标均符合羊肚菌精量播种的农艺技术要求。该机具显著降低了人工操作强度,作业效率较传统人工播种方式提高5倍以上,为羊肚菌的规模化种植提供了高效、可靠的机械化解决方案。

     

    Abstract: To address the technical challenges in the artificial sowing of morel mushroom, such as high labor intensity, poor seeding uniformity, and easy accumulation of spawn, a lightweight precision seeding machine based on electric control technology was designed. This mechanical device adopts a double-layer structure, with its core components comprising a stirring mechanism, a metering device, a sprocket device system, and a traveling mechanism. Through the coordinated action of a two-stage stirring device (a primary stirring barrel and a secondary stirring disc), it effectively overcomes issues like spawn adhesion, blockage, and uneven seeding under high-humidity conditions (60%~65%). Field test results show that the implement performs well at an operating speed of 15 m/min, with the sowing uniformity error less than 10 % and no blockage occurring. When the feeding outlet is fully opened, the sowing rate is stably maintained at 1.0±0.1 kg/m2. All performance metrics met the agronomic requirements for precision sowing of morel mushroom. This machine significantly reduces manual labor intensity and improves operational efficiency by more than five times compared with traditional manual sowing methods, providing an efficient and reliable mechanized solution for the large-scale cultivation of morel mushroom.
